Description

Technical Field

[0001] The utility model relates to the technical field of tooling trolley devices, in particular to a contour tooling trolley. Background Art

[0002] It refers to a small mobile work platform with a specific height adjustment function used in industrial production or maintenance fields. It is generally used for the transportation of objects or for operations at different heights. The use of a height-adjustable work trolley can provide different height supports for workers to facilitate their work. In addition, the work trolley is very convenient for transporting objects because of its ability to change height. When working on high buildings, it is often necessary to deliver different materials from the bottom to the top. The use of a work trolley can effectively save manpower expenses.

[0003] For example, a multifunctional tooling trolley with the announcement number CN117720048A includes a base, and folding plates are fixedly connected to the left and right sides of the top middle part of the base, the tops of the two folding plates are fixedly connected to a platform, the bottom middle part of the platform is fixedly connected to an accelerator, the left and right ends of the base are fixedly connected to fixed blocks, the two fixed blocks are fixedly connected to telescopic rods at the ends away from each other, the two telescopic rods are fixedly connected to legs at the ends away from each other, the top middle parts of the two fixed blocks are fixedly connected to guardrails, the tops of the adjacent sides of the two guardrails are fixedly connected to support rods, the bottom ends of the two support rods are fixedly connected to the left and right sides of the top middle part of the base, the top middle part of the base is fixedly connected to a sensor, and the bottom ends of the two legs are fixedly connected to anti-slip pads.

[0004] The above-mentioned device can directly transport surveyors and measuring equipment to the designated location through the coordinated use of the base, folding plate and platform, which not only effectively ensures the work safety of surveyors, but also saves the time of climbing up and down and transporting equipment, greatly improving work efficiency. However, the design of the above-mentioned device has defects. Although there is bottom support in the longitudinal direction, there are no other components to fix or support it in the lateral direction. Once it is subjected to other forces or the force distribution at the upper end is uneven, the upper folding plate may become skewed and collapse. In addition, the stacked folding plate design cannot withstand large forces, which can easily cause damage to the connecting parts. Utility Model Content

[0023] refer to Figure 2The main body is a rotating end 6, one side of the rotating end 6 is provided with a perforation, and a brake pad 4 is assembled inside the perforation, and a friction surface is provided on the surface of the brake pad 4. The brake pad 4 is installed at the upper end of the rotating wheel 5. When in use, it is only necessary to step on the brake pad 4 to give the rotating wheel 5 a huge friction, so that the rotating wheel 5 stops, which gives the device a greater degree of convenience when in use, so that the device can be stopped at any time and remain stable. The outer side of the bearing structure is equipped with an external frame rod 1, and the inner side of the external frame rod 1 is equipped with an inlay end, and a bearing plate 12 is assembled inside the inlay end. The inlay block is riveted to the inner surface of the external frame rod 1, so that it can move laterally on the external frame rod 1, and the bearing plates 12 of the internal device are evenly distributed, which can carry both material objects and operators;

[0024] refer to Figure 3 The main body is a connecting rod, the lower end of the connecting rod is assembled with an assembly block 8, and the lower end of the assembly block 8 is installed with a tension spring 7, the upper end of the connecting rod is assembled with a connecting block, the upper end of the connecting block is assembled with a steel wire rope 11, and the surface of the support rod 2 is assembled with a reversing wheel 15, and the outer surface of the load-bearing structure is assembled with a connecting block 14.

After completion, the connecting rod is moved to the upper end, and the design of the wire rope 11 and the steering wheel is used to move the upper end of the bearing structure to the lower end, so that the materials or workers can stand on the upper end of the bearing structure. Then, the height of the connecting rod is adjusted by manpower or the assistance of other machines, and changes are made from time to time according to the needs of the operation, which is convenient for the operator to continue working, and the position of the device can be changed at any time while ensuring stability.
