Description

Technical Field

[0001] This invention relates to the field of transportation, and more particularly to a transportation device for pile foundation steel cages. Background Technology

[0002] The fabrication and installation of reinforcing cages is an essential step in pile foundation construction. The reinforcing cages are fabricated uniformly in the reinforcing shed using a rolling welding machine, and then transported to the site via a transportation device.

[0003] A search revealed Chinese patent application CN218289129U, which discloses a transportation device for pile foundation reinforcement cages. The device includes a rectangular, welded steel frame support frame. Multiple sets of roller assemblies are arranged laterally along the length of the support frame. Universal wheels are installed at the bottom of the four corners of the rectangular support frame, and limiting structures are installed at the top of the four corners. Each roller assembly consists of a roller body and roller shafts. The roller shafts are welded and fixedly installed on the two long sides of the support frame, and the roller bodies are fitted onto the roller shafts for rolling cooperation. This utility model transportation device allows workers to move the reinforcement cage freely after processing without the need for hoisting equipment. It also enhances the protection of the finished reinforcement cage, ensuring that it does not deform during movement. The application of this utility model device requires no special skills from construction personnel and solves the problem of rework due to inadequate protection of the finished product during the transfer of reinforcement cages, thus saving on personnel, equipment, and construction materials, and reducing construction costs.

[0004] In existing equipment, when transporting and handling reinforcing cages, the cages are usually placed on the equipment and secured by a fixing mechanism. However, during transportation, road bumps can cause the reinforcing cages to move due to vibration, which can change the center of gravity of the cages on the equipment and lead to the cages falling off. Summary of the Invention

A pull-out opening is provided through one side of the support frame. The pull-out opening is slidably connected to the top rods. The two ends of the top rods are hinged to the other ends of the side plates and the swing plates respectively. A third spring is bolted to one side of the clamping plate and the side plates.

[0011] Preferably, an airbag is bonded between one side of the clamp and the side plate, a cavity is opened inside the clamp, a guide hole is opened through one side of the cavity and the airbag, a plurality of anti-slip grooves are opened through one side of the cavity, and an anti-slip pad is provided on the inner wall of the anti-slip groove.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention, through its supporting and fixing mechanisms, allows for the adjustment mechanism to be activated based on the length of the pile foundation reinforcement cage during transportation. This mechanism moves two auxiliary support plates towards one side of the main support plate. After adjustment, the pile foundation reinforcement cage is placed between the two auxiliary support plates and the main support plate, supported on the limiting seat. At this time, the pad plate moves downwards under the weight of the pile foundation reinforcement cage, squeezing the two push plates. The squeezed push plates push the slider to one side, which in turn pushes the push rod to one side. This movement causes one end of the swing plate to deflect to one side, while the other end deflects to the other side under the action of the swing frame. This deflection causes the top rod to slide to one side, pushing the side plate to one side. As the side plates move, they simultaneously move the clamping plates. The clamping plates act on both sides of the pile foundation reinforcement cage, clamping and fixing it while simultaneously compressing the airbags. The compressed gas inside the airbags is then transported through guide holes into the cavity, increasing the air pressure. This causes the anti-slip pads to bulge under the pressure, adhering tightly to the surface of the pile foundation reinforcement cage, thus increasing the friction between the cage and the clamping plates. The cooperation between the support and fixing mechanisms effectively secures the pile foundation reinforcement cage, improving its stability during transport and preventing movement due to vibrations during transport. This prevents the cage from shifting its center of gravity on the device and potentially detaching during transport.

[0017] 2. This invention, through the setting of a fixing mechanism and a limiting mechanism, when the pile foundation reinforcement cage is fixed during transportation by the fixing mechanism, the connecting seat moves synchronously with the movement of the side plate. The moving connecting seat drives the gear to move, and the gear meshes with the first rack during movement. The gear rotates under the action of meshing, and during rotation, the meshing causes the second rack to slide the extension plate to one side. Because the second rack and the extension plate are inclined, the extension plate moves downwards at an angle under the action of the gear and the second rack. At this time, one end of the extension plate acts on one side of the top of the pile foundation reinforcement cage as it moves downwards, thus facilitating the limiting treatment of the pile foundation reinforcement cage during transportation. The cooperation between the fixing mechanism and the limiting mechanism effectively fixes the pile foundation reinforcement cage, thereby improving the stability of the pile foundation reinforcement cage during transportation.
