Star-wheeled transporter for construction site

Abstract

The invention belongs to the technical field of conveyor trucks, in particular to a star-wheeled transporter for construction site. The star-wheeled transporter includes a handbrake, an L-shaped panel, a star-wheeled mechanism, a support shaft, and a gear disk. wherein the conveyor of the invention utilizes the rotation of the Y-shaped bracket when climbing the stairs, the first gear on the Y-shaped support revolves around the outer circular surface of the gear plate, 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 limit rack to be inserted into the gap between two adjacent limit plates on the ring sleeve more deeply, the rotation of the planetary wheel, the rotation shaft and the ring sleeve is completely restrict, and the dangerous phenomenon that the planetary wheel slips when climbing the stairs due to the planetary wheel causes the carriage to roll is avoided. In addition, the strip-type telescopic plate jacket, the first strip-type telescopic inner plate and the second strip-type telescopic inner plate are designed so as to disengage the second wheel from the engagement relationship with the limiting rack, 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 star-wheel type transport vehicle used in construction sites. 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
