Q:The calculation of the use of electricity in the construction elevator
Use electricity in the field (1) lifting equipment class: tower crane 2, construction elevator 3; According to the table, K = 0.3 cos phi = 0.7 tg phi = 1.02 JC = 40% (temporary load) Pe = 2 times 63 + 3 times 11 = 159 (kW) And then power: PS = 2 times Pe = 2 times 159 = 201 (kW) Pjs1 = K * PS = 0.3 * 201 = 60.3 (kW) Qjs1 = tg phi by Pjs1 = 1.02 times 60.3 = 61.5 (kVA)
Q:Is the construction elevator a special equipment
The construction elevator is a special equipment. Special equipment is related to life safety, greater danger of boilers, pressure vessels (including gas cylinders), pressure pipes, elevators, lifting machinery, passenger ropeway, large-scale amusement facilities and field special motor vehicles (factory) in these eight types of equipment. In order to guarantee the safe operation of the special equipment, the state of all kinds of special equipment, in three stages: from the production, use, the examination has strict rules, is a whole process supervision. According to a 2013-2017 China special equipment inspection testing industry market foresight strategic planning and investment analysis report statistics, by the end of 2011, the national special equipment comprehensive inspection agency has reached 545, including quality inspection department inspection institutions, industry inspection institutions and enterprises self-checking, in addition to type testing institutions, nondestructive testing institutions, cylinder inspection institutions, etc.
Q:Safe use of construction elevator
1. Construction enterprises must establish and improve the construction lifter of all kinds of management system, the implementation of the professional institutions and management personnel, clear the safe use and management responsibility system at various levels. The driver of the elevator should be trained by the competent department of the relevant administrative department for the training of qualified personnel. The driver should do the routine inspection, namely, when the elevator is first run, each class should be free and full of trial operation. 4. Establish and implement the system of regular inspection and maintenance, each week or each ten-day of elevator to conduct a comprehensive inspection, to find out the hidden dangers in accordance with the "armed" principle to carry out the rectification. After the rectification must be checked and confirmed by the relevant personnel, the safety requirement will be used.
Q:Safety device for construction elevator
1. The governor To prevent the hanging basket construction elevator overspeed or fall and set up a safety device, is divided into a unidirectional and bidirectional type two kinds, the one-way speed limiter can only along the direction hoisting cage falling within the speed limit, two-way speed limiter can up and down along the hoisting cage speed effect on two directions. The speed limit shall be tested for performance in accordance with the prescribed time limit. 2. The buffer spring Buffer spring in spring seat connected to the base frame, so that when hanging cage fall accidents, reduce the impact of the hanging basket, at the same time ensure crane cage and weight drops landed into flexible contact, slow down the hoisting cage and the impact of weight landing. The buffer spring has a cone winding spring and a cylindrical spiral spring. Usually, there are two or three cone coiled springs or four cylindrical coils on the base of each cage.
Q:Elevator installation approach, need to give the total package (inspect) what data, come a master to answer the detail point
In ten days: installation company qualification (including business license, qualification certificate, safety production license, organization code certificate and company performance, etc.), installation personnel qualifications (including the principal, special operations personnel, etc.), installation construction scheme (including the construction organization design, safety and civilized construction scheme, construction progress) The installation process: in materials to submit for approval (material inspection report, certificate, etc.), play equipment to submit for approval (mechanical factory qualified certificate, safe use license, etc.) After the construction is completed, the certificate of safety inspection (which needs to be provided by the special security agency)
Q:Why is the construction elevator not so close to the structure?
Isn't there a car? Normally, the center line of the car should be in the same line as the support frame center. If the frame body (standard) get into the building, inevitably cause capsules center, usually the center of gravity and center is not a straight line on the standard section, capsules will force up and down roller, increase and the frame body wear, and certainly not safe.
Q:Do the elevator need to be installed when the main project is in construction
The top brass usually need to install the construction elevator.
Q:What are the requirements for the construction elevator
The anti-drop safety device is an important part of the construction elevator, which can be relied on to eliminate the occurrence of the fall accident and guarantee the safety of the crew. So for safety device factory test is very strict, before delivery by the statutory inspection unit for torque measurement, critical speed measurement, measuring the amount of spring compression, each with the test report, after assembly to the construction lifter for drop test under rated load, and the site to use the elevator must be every three months to conduct a drop test. For safety device to the factory for two years for safety device (delivery date), must also be sent to the statutory inspection unit to carry on the test, after testing once a year. So far few inspection, some sites even once every three months to detect don't do drop test, all think that their is no problem for safety device, but once had an accident, repent at leisure. Why not do regular tests and tests? The use of units blindly thinks that not bad is good. Actually good or bad for safety device can only judge by test and inspection in the daily operation is not sure whether it is good or bad, for those who are serving for safety device, or advice for the earlier inspection and regular test, only accomplish know fairly well, to malignant accident prevention rather than cure.
Q:What is the meaning of double straps in the construction elevator?
With double cage for heavy, namely SCD200/200 series Is the two cages, each cage has a corresponding weight, the weight up and down in the elevator cage rise to energy conservation and reduce the reaction between the up and down, when you imagine front-rear door principle is about the same
Q:How many years does the construction elevator usually use?
In principle, eight years; But for eight years has scrapped section standard of standard section pillar thickness wear to design thickness of 1/4 (like this value) will be scrapped or downgrade use; After eight years, the construction elevator can also be used, but the structural parts need to be broken and the test can be used again. The pendant safety device for the construction elevator is required to be tested every year for five years.
