Description

Technical Field

[0001] This invention relates to the field of transfer device technology, specifically to a tool transfer device for construction sites. Background Technology

[0002] During the construction process, it is usually necessary to use transfer devices to transport construction tools. Commonly used transfer devices include towed flatbed trailers. The construction tools are placed on the flatbed trailer, and then the towed flatbed trailer is pulled to the designated location by external towing equipment, thereby realizing the transportation of construction tools.

[0003] However, the above-mentioned towed flatbed trailers still have some shortcomings in use: Since the environment at construction sites is usually poor and the ground is often uneven, when using conventional towed flatbed trailers to transport tools, the flatbed is prone to tilting when encountering uneven ground, which can easily cause tools to fall off the flatbed. This not only easily leads to tool damage, but also wastes a lot of time and manpower to reload the tools. Summary of the Invention

[0034] The traction mechanism 2 includes a fixed plate 25 and a traction frame 26. The fixed plate 25 is fixed to the crossbeam 7, and the traction frame 26 is hinged to the fixed plate 25. The traction frame 26 is provided with a traction ring 29. A sliding rod 27 is slidably provided on the traction frame 26. The traction ring 29 is provided on the sliding rod 27. A third spring 28 is sleeved on the sliding rod 27. The two ends of the third spring 28 are respectively provided on the traction frame 26 and the sliding rod 27.

[0035] The locking mechanism 3 includes a nut sleeve 30, a threaded support column 31, and a support leg 32. The nut sleeve 30 is mounted on the flatbed vehicle body 4. The threaded support column 31 is threadedly connected to the nut sleeve 30. The support leg 32 is rotatably mounted on the bottom of the threaded support column 31. The threaded support column 31 has a through hole, and a rotating rod 33 is slidably mounted in the through hole. Both ends of the rotating rod 33 are provided with anti-detachment balls 34. The bottom of the support leg 32 is provided with an anti-slip pad 38.

[0036] In actual use, the staff places the tool to be transferred on the flatbed 4. Depending on the actual needs, the tool can also be fixed by binding or other methods. Then, the external traction device is connected to the traction ring 29. At this time, the external traction device can drive the transfer device to move and transfer the tool. During the process of the transfer device being pulled by the external traction device, the third spring 28 can play a good buffering function.

[0037] Because construction sites are typically in poor condition with uneven surfaces, using conventional towed flatbed trailers for tool transport can easily cause the trailer body 4 to tilt, leading to tools falling off. This not only damages the tools but also wastes considerable time and manpower reloading them. This transport device effectively solves these problems. When using this device to transport tools, if encountering uneven ground, the self-balancing frame 1 can automatically adjust its balance, reducing the tilt of the flatbed body 4 and preventing tools from falling off due to tilting. The self-balancing process of this transport device is as follows:

[0038] When one of the wheels 12 passes over a pothole, the connected crossbeam 7 will tilt to a certain extent, causing the wheel 12 to move down a certain distance. However, because the longitudinal beam 5 connects the front and rear sets of crossbeams 7 and has a certain rigidity, the degree of tilt (or bending at one end) that the crossbeam 7 can produce is relatively small. This results in the wheel 12 moving down a relatively small distance with the crossbeam 7, which is insufficient to compensate for the depth of the pothole. At this time, the parallelogram formed by the first mounting plate 14, the second mounting plate 15, the first connecting plate 16, and the second connecting plate 17 needs to deform to fill the distance difference (that is, when the wheel 12 slowly passes over the pothole, it will definitely contact the bottom of the pothole and will not be suspended in the air). When the first connecting plate 16 and the second connecting plate 17 tilt, the second mounting plate 15 moves downward, causing the wheel 12 to move downward and contact the ground in the pothole. During the tilting process, the first hydraulic cylinder 18 is compressed, and the hydraulic oil in the first hydraulic cylinder 18 enters the second hydraulic cylinder 19 through the oil pipe 21, pushing the piston rod of the second hydraulic cylinder 19 a certain distance. The piston rod of the second hydraulic cylinder 19 pushes the connected adjusting support rod 10 to rotate, and lifts the tilted side of the flatbed 4, thereby reducing the tilting amplitude of the flatbed 4. This helps to solve the problem of tools falling due to the tilting of the flatbed 4.

[0039] Once the transfer device is moved to the designated position, the rotating rod 33 is rotated, which drives the threaded support 31 to move down. The threaded support 31 then drives the support leg 32 to move down and contact the ground, thereby locking and positioning the transfer device and preventing it from moving during the loading and unloading of tools.

[0040] In summary, this solution includes a self-balancing frame 1. When using this transfer device to transport tools on the construction site, the self-balancing frame 1 can better adapt to uneven ground and can adjust itself according to the ground conditions, thereby reducing the tilt of the flatbed 4 and helping to solve the problem of tools falling off due to the tilt of the flatbed 4. This solution also includes a traction mechanism 2, which facilitates the traction of the transfer device, and the third spring 28 provides a good cushioning effect during traction. Finally, this solution includes a locking mechanism 3, which can lock and fix the transfer device after it has moved to the designated position, thus better ensuring the stability of the transfer device when loading and unloading tools.
