Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a curbstone transfer device for road and bridge construction. Background Art

[0002] The laying of curbstones is a crucial step in road and bridge construction. Curbstones serve to separate the road surface from the shoulder and protect the road edge. Currently, the transportation of curbstones faces several challenges: Traditional methods of transporting curbstones often rely on manual handling or simple carts. Manual handling is not only labor-intensive and inefficient, but can also pose a risk of injury to construction workers. Consequently, a number of curbstone transport devices have emerged on the market to facilitate efficient curbstone transport.

[0003] For example, Chinese patent number CN201821386651.9 discloses a curbstone handling device, which includes a frame, wheels are provided below the frame to form a trolley, a support rod is provided above the frame along the front and rear directions of the trolley, and the support rod forms a lever structure that can rotate back and forth; the rear end of the support rod is an operating end, and a downward clamping mechanism is provided below the front end of the support rod. The lower end of the clamping mechanism is a clamping opening for the curbstone to enter and clamp, and the clamping mechanism is installed at the front end of the support rod through a front and rear adjustment mechanism. This curbstone handling device is convenient for hoisting curbstones of different weights and can more conveniently adjust the angle of the curbstone to facilitate curbstone installation.

[0004] The curbstone transport device provided by the above patent requires the worker to press down one end of the transport device when in use before the curbstone can be pushed to move. This method requires the worker to bend over to operate when transporting the curbstone, and the worker also needs to continuously apply downward pressure on the transport device, which consumes a lot of physical strength of the worker and is not conducive to the worker's efficient work.
