Q:What are the mixing arms of the concrete mixer?

Mixing arm concrete mixer is a component of the mixing arm itself and divided into lateral mixing arm (positive and negative points), stirring arm (also have positive and negative points), stirring arm below is the bearing seat connected, connected with 4 sets of high strength bolts with stirring arm. The top is equipped with wear-resistant mixing blades, connecting with mixing blades, high-strength bolts 2 sets. In addition, some manufacturers have designed mixing side bonded shaft swivel, is installed in the interval between the stirring arm fixed and rotated in two ways.

Q:Construction Engineering, moving equipment and stationary equipment, respectively

Moving equipment refers to the rotating equipment driven by a drive (i.e., equipment with energy consumption), such as pumps, compressors, fans, etc. the energy can be electric power, pneumatic power, steam power and so on. Moving equipment refers to the main components of the movement of machinery, such as various filters, crushers, centrifuges, rotary kiln, mixer, rotary dryer and fluid conveying machinery

Q:Where are the hanging baskets for the building?

It is forbidden to take a stool or put a ladder on a hanging basket to work higher; it is not allowed to work alone in a basket, and no electric machinery or equipment can be placed in the basket;

Q:Where are the mechanical pressurization air supply facilities set up?

The purpose of setting up a mechanical pressurization air supply smoke prevention system is to provide evacuation routes and shelters without smoke interference in the event of a fire in the building. Therefore, in the closed door, pressing position, and the fire floor must maintain a certain pressure difference, the position of the air pressure value is a relative positive pressure); at the same time, in the open part of the pressure when the door can have enough air velocity in the opening section, to effectively prevent the intrusion of flue gas, the safety of personnel ensure evacuation and refuge.

Q:What measures can effectively reduce the construction accident rate?

Hefei construction workers training _ limited energy or hazardous substances: conditions of actual technical and economic constraints, some risk sources can not be eradicated, then they should try to limit with energy or hazardous substances, reduce the risk of. Reduce the amount of energy or dangerous substance.

Q:What type of industry does the machinery and building accessories processing belong to?

Q:What functions should be achieved in mechanical structure design?

Mechanical structure design plays an important role in mechanical design. This chapter mainly discusses the characteristics, steps and mode of thinking of mechanical structure design. The working principle and design requirements of the machine assembly is a major factor in determining the structure and shape of the parts, followed by the selection of materials, manufacturing process requirements, which has the advantages of good manufacturability (processing and assembly). In addition, the perfection of the structure and shape of the parts has a great influence on the strength and stiffness.
