A truck used on a construction site

Abstract

The invention belongs to the technical field of conveyor trucks, in particular to a transporter for use at a construction site, It includes a handbrake, a L-shaped panel, a star wheel mechanism, Support shafts and gear disks, etc. wherein the conveyor of the invention utilizes the rotation of the Y-shaped bracket when climbing the stairs, such that the first gear revolves around the outer circularsurface of the toothed disk, the first gear can rotate the second gear counterclockwise through the telescopic rod under the action of the first one-way clutch ring, The second gear drives the outersleeve of the torque-type telescopic plate to move toward the direction of the second unidirectional clutch ring, and the arc-shaped plate tightly presses the outer ring of the second unidirectional clutch ring, so that the rotation of the planetary wheel in the advancing direction is completely restricted, thereby avoiding the dangerous phenomenon that the planetary wheel rolls when climbing thestairs due to the slip of the planetary wheel. In addition, the strip-type telescopic plate outer cover, the first strip-type telescopic inner cover and the second strip-type telescopic inner cover are designed so as to disengage the second wheel from the engagement relationship with the rectangular-type telescopic plate outer cover, thereby removing the rotation restriction on the planetary wheel.

Description

technical field [0001] The invention belongs to the technical field of transport vehicles, in particular to a transport vehicle used in a construction site. Background technique [0002] At present, many building materials in construction sites are transported by trucks. Trucks are not only convenient for transporting building materials on flat roads, but also use slopes to transport building materials from low places to high places; however, when it is necessary to use When the truck transports building materials from a low place to a relatively high position, the slope is also difficult for the truck to reach a relatively high height, especially when transporting building materials in a building with stairs, traditional trucks cannot climb Stairs: Although there are star-wheeled trucks for climbing stairs in reality, traditional star-wheeled trucks are prone to misalignment and slipping when climbing stairs, which poses certain safety hazards.

[0002] At present, many building materials in construction sites are transported by trucks. Trucks are not only convenient for handling building materials on flat roads, but also use slopes to transport building materials from low places to high places; however, when it is necessary to use When the truck transports building materials from a low place to a relatively high position, the slope is also difficult for the truck to reach a relatively high height, especially when transporting building materials in a building with stairs, traditional trucks cannot climb Stairs: Although there are star-wheeled trucks for climbing stairs in reality, traditional star-wheeled trucks are prone to misalignment and slippage when climbing stairs, and there are certain safety hazards

Since the traditional star-wheel truck does not have the anti-skid brake function, human traction is required to prevent it from sliding down when going up and down the stairs. Once it slips, it will be difficult to control
