Description

A height-adjustable clamp cart Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a liftable clamp table cart. Background Technology

[0002] In industrial production, equipment maintenance, and logistics handling, the demand for workbenches and material lifting equipment is increasing. Traditional fixed workbenches or simple lifting devices suffer from problems such as a contradiction between stability and flexibility, fixed height that cannot be adjusted, and complex structures that are inconvenient to disassemble, making them difficult to adapt to the needs of different working heights or complex scenarios. In addition, ordinary clamping carts have limited functions and cannot balance stability and portability, especially performing poorly in confined spaces or frequent movement conditions.

[0003] In recent years, detachable and lifting technologies have been gradually applied to the field of tooling equipment. For example, lifting platforms that achieve height adjustment through hydraulic or mechanical transmission, or tool tables with modular designs for easy assembly and disassembly. However, these solutions often suffer from drawbacks such as complex structures, high costs, or insufficient load-bearing capacity. In particular, some height-adjustable lifting platforms are equipped with sliding wheels, which are constrained in the sliding grooves and serve as the connecting structure for driving the platform's lifting. They bear the load and reciprocating sliding motion, making them vulnerable parts. When damaged, replacement requires disassembling or cutting open the sliding grooves, which is extremely inconvenient. Summary of the Invention

[0039] Please refer to Figures 1-4, which are schematic diagrams of the overall structure of the height-adjustable clamp table cart according to an embodiment of the present invention; schematic diagram of the lifting component structure according to an embodiment of the present invention; enlarged schematic diagram of the sliding wheel structure according to an embodiment of the present invention; and enlarged schematic diagram of the foot pedal loading component structure according to an embodiment of the present invention.

[0040] This utility model provides a height-adjustable clamp cart, comprising:

[0041] The upper frame 1 is a rectangular frame. A groove 11 is provided on the inner side of the upper frame 1 along the long direction. An installation notch 12 is provided on the ground of the rear edge of the groove 11. The installation notch 12 is completely connected to the groove 11.

[0042] The lower frame 2 is symmetrical to the upper frame 1 in plane.

[0043] The lifting assembly 3, used to limit the distance between the upper frame 1 and the lower frame 2, includes an inner support unit 31 and an outer support unit 32 that are hinged together, and a lifting drive unit 33 for limiting the relative angle between the inner support unit 31 and the outer support unit 32. The top end of the inner support unit 31 is hinged to the inner side of the rear end of the upper frame 1, and the bottom end of the inner support unit 31 is slidably disposed in the slide groove 11 of the lower frame 2. The bottom end of the outer support unit 32 is hinged to the inner side of the rear end of the lower frame 2, and the top end of the outer support unit 32 is slidably disposed in the slide groove 11 of the upper frame 1. Compared with the prior art, the installation notch 12 reserved in the slide groove 11 facilitates the replacement of the inner support unit 31 and the outer support unit 32. Thus, when the vulnerable sliding wheel is damaged, it can be disassembled and replaced through the installation notch 12, thereby improving the service life of the vise table cart.

[0044] Specifically, in this embodiment, each hinge can be connected using bolts and nuts, or using hinge rods. There are no specific limitations. For example, the hinge between the inner support unit 31 and the outer support unit 32, the hinge between the top of the inner support unit 31 and the rear end of the upper frame 1, the hinge between the bottom of the outer support unit 32 and the rear end of the lower frame 2, and the hinges at various points of the lifting drive unit 33 are not shown in the figure.

[0045] Specifically, the inner support unit 31 includes two parallel inner hinge rods 311, an upper hinge seat 312, an inner sliding rod 313, and a sliding wheel 314.

[0046] The inner hinge rod 311 is hinged to the upper hinge seat 312. Two upper hinge seats 312 are fixedly mounted on the inner side of the rear end of the upper frame 1. The inner sliding rod 313 is fitted through the bottom end of the inner hinge rod 311 with a clearance, and its function is to adjust the distance between the upper frame 1 and the lower frame 2. Since the inner sliding rod 313 has sliding wheels 314 at both ends, and the outer diameter of the sliding wheels 314 is smaller than the width of the slide groove 11, it facilitates the movement of the inner sliding rod 313 within the slide groove 11. This reduces the mechanical wear of the inner support unit 31.

[0047] Specifically, the outer support unit 32 includes two parallel outer hinge rods 321, a lower hinge seat 322, an outer sliding rod 323, and a sliding wheel 314;

The outer sliding rod 323 is fitted through the top end of the outer hinge rod 321 with clearance, and its function is to adjust the distance between the upper frame 1 and the lower frame 2. Sliding wheels 314 are respectively provided at both ends of the outer sliding rod 323. The outer diameter of the sliding wheels 314 is smaller than the width of the sliding groove 11. This facilitates the movement of the outer sliding rod 323 within the sliding groove 11, thereby reducing the mechanical wear of the outer support unit 32.

[0049] Specifically, the lifting drive unit 33 includes a loading rod 331, a loading base 332, a loading hydraulic cylinder 333, a hydraulic cylinder fixing base 334, and a foot pedal loading assembly 335.

[0050] The loading rod 331 is fixedly positioned between the two inner hinge rods 311 and below the junction between the inner hinge rod 311 and the outer hinge rod 321. The loading base 332 is vertically fixedly mounted on the loading rod 331. One end of the loading hydraulic cylinder 333 is connected to the top of the loading base 332, and the other end of the loading hydraulic cylinder 333 is hinged to the hydraulic cylinder fixing base 334. The hydraulic cylinder fixing base 334 is fixedly connected to the bottom end face of the lower frame 2. The load input end of the loading hydraulic cylinder 333 is connected to the foot pedal loading assembly 335. This facilitates the lifting drive unit 33 to drive the inner support unit 31 and the outer support unit 32 to slide towards each other. This meets the practical need of the pliers table carriage in actual working conditions where multi-level height adjustment is not possible.

[0051] Specifically, the foot pedal loading assembly 335 includes a foot pedal 3351, a rotating shaft 3352, a loading top block of the rotating shaft 3352, and a loading hinge block 3354;

[0052] The rotating shaft 3352 is hinged to the hydraulic cylinder mounting base 334. The foot pedal 3351 is fixedly mounted at the end of the rotating shaft 3352 away from the hydraulic cylinder. The top end of the loading top block of the rotating shaft 3352 is fixedly mounted on the rotating shaft 3352. The bottom end of the loading top block is hinged to one end of the loading hinge block 3354. The other end of the loading hinge block 3354 is connected to the load input end of the loading hydraulic cylinder 333. This configuration facilitates the transmission of power from the foot-operated loading assembly 335 to the lifting drive unit 33, reducing the difficulty for the user.

[0053] Specifically, the top of the upper frame 1 is provided with a perforated worktable 4, which is used to improve the functionality of the clamp table cart.

[0054] Specifically, the lower frame 2 is provided with casters 21 at the four corners of its bottom end.

[0055] Specifically, brake pedals 22 are provided on the two omnidirectional wheels 21 near the lifting assembly 3, which can control the braking of the clamping table carriage and solve the practical need for the clamping table carriage to have both stability and flexibility in actual working conditions.

[0056] Specifically, the bottom end of the porous worktable 4 is provided with reinforcing ribs 41, which enhances the stability of the porous worktable 4.

[0057] Specifically, a handle 42 is inserted into the side of the upper frame 1 near the lifting component 3. It can be understood that this arrangement facilitates the user's movement of the clamp table cart.

[0058] Specifically, a bakelite locking bolt 43 is provided on the bottom side of the upper frame 1 near the handle 42. The top of the bakelite locking bolt 43 abuts against the handle 42 to fix the handle 42 and prevent the user from pulling the handle 42 off when moving the pliers cart.

[0059] Specifically, a lowering and releasing pedal 44 is provided at the bottom of the lower frame 2 near the loading hydraulic cylinder 333. This arrangement facilitates the user's quick release of force from the loading hydraulic cylinder 333 and makes it convenient for the user to adjust the height of the clamp table carriage.

[0060] For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
