Description

Bridge type screw car unloader

Technical Field

The utility model mainly relates to a train coal unloading device field especially relates to a bridge type spiral car unloader.

Background

The screw unloader is divided into a bridge type and a door type according to the whole structure. The bridge type screw unloading machine consists of a metal bridge frame, an operation room, a screw rotating mechanism, a screw lifting mechanism, a cart traveling mechanism and the like. The structure is simpler, the equipment is light, and the operating condition is better when the coal receiving pit with the room cover is arranged. The gate-type screw unloader is heavy, generally works in the open air, and the operating environment is poor. The screw unloader has the advantages of reliable operation, simple structure, easy manufacture, convenient maintenance, no damage to vehicles and the like.

However, the flow is extremely uneven in the unloading process, a large amount of materials flow out in the initial stage after the car door is opened, the difference between the flow and the flow of the materials which are completely pushed out of the car by the spiral in the final stage is large, the car stops running due to excessive accumulated materials during unloading operation, and the operation condition is severe because the dust is difficult to control.

Preferably, the bridge frame 1 comprises two main metal beams 7, and the end of each main metal beam 7 is rigidly welded to an end beam of the bridge frame 1.

Preferably, the lifting device 2 is fixedly arranged on the bridge frame 1 through a trolley metal frame.

Preferably, the lifting device 2 is composed of a motor, a reducer and a brake, the motor outputs torque, and the spiral rotating mechanism 3 and the cleaning device 4 are driven by the reducer and the chain wheel assembly to spirally lift.

Preferably, the running mechanism 6 is composed of a motor and a speed reducer, and adopts a double-side driving mode.

Preferably, a closed cab 8 is welded between channel steels at the lower end of the bridge frame 1.

Preferably, the closed cab 8 is connected with an electrical device 9 through a cable, and the unloading operation is performed by operating the electrical device 9.

The utility model has the advantages that:

through at the crane span structure four corners department installation polyurethane buffer, can avoid because of long-pending too much and overload stall, through installation cleaning device, function when spiral rotating mechanism work, effectively reduce the dust that produces in the working process, improve operational environment's comfort level.
