As shown in a special mobile lifting platform vehicle for narrow aisles (publication number CN216336461U) disclosed by the Chinese Patent Network, such a device improves the moving stability of the lifting platform vehicle by installing a pulley damper device on the lifting platform vehicle, and uses the extension of the scissor link group to push the lifting platform to lift and displace to perform high-altitude tasks.

[0003] However, for the above-mentioned disclosed patents and the lifting platforms adopted in the existing market, there are still some deficiencies: the existing form of the scissor link group assembled by multiple sets of winches, due to the integral linkage form between the scissor links, when the components are worn, it is extremely easy to loosen as a whole, resulting in poor lifting stability of the lifting platform and reduced safety of high-altitude operations. Therefore, the technical personnel in this field provide a highly stable lifting platform with an attachment reinforcement structure to solve the problems raised in the above background art. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a highly stable lifting platform with an attachment reinforcement structure, which solves the problem of poor linkage stability of the lifting components of the existing lifting platform raised in the above background art.

[0016] The utility model provides a high and stable lifting platform with an attached reinforcement structure, which has the following beneficial effects compared with the prior art:

[0017] The lifting platform of this design is based on the horizontal combination of a bottom support frame, a braking frame, and a top support frame. Under the telescopic support of two independent sets of telescopic jibs, by using a braking mechanism as the driving source, the two sets of telescopic jibs are driven to expand and contract in an independent operation mode, pushing the workbench to lift and displace.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution for a highly stable lifting platform with an attachment reinforcement structure: A highly stable lifting platform with an attachment reinforcement structure includes a bottom support frame 1, a braking frame 2, and a top support frame 3 that are horizontally arranged opposite to each other. At both ends of the brackets of the bottom support frame 1, support casters 5 are arranged in a pairwise symmetric form, and at the bottom of the brackets of the bottom support frame 1, a foot support positioning mechanism is arranged in a symmetric form. The foot support positioning mechanism includes lifting electric push rods 14 that are pairwise symmetrically installed on both sides of the brackets of the bottom support frame 1. The telescopic ends of the lifting electric push rods 14 are provided with guide rail frames 15, and at both ends of the slide rails of the guide rail frames 15, telescopic guide rails 16 are slidably connected in a symmetric form. One end of the bracket of the telescopic guide rail 16 is installed with a support foot seat 6. The track length of the telescopic guide rail 16 is half of the slide rail length of the guide rail frame 15. After pushing the lifting platform to the designated position by using the support casters 5, based on the sliding combination of the telescopic guide rail 16 and the guide rail frame 15, the support foot seat 6 can be extended out by an appropriate length, and then based on the telescopic braking of the lifting electric push rod 14, the support foot seat 6 is pushed downward to contact the ground, replacing the support casters 5 to provide fixed-point support for the lifting platform, so as to improve the support stability of the lifting platform when standing on site.

[0025] The bottom support frame 1 and the braking frame 2 are connected by first telescopic hinge frames 7 arranged in a pairwise symmetric arrangement. On both sides of the brackets of the bottom support frame 1, first guide rail frames A9 that are in guiding adaptation with the first telescopic hinge frames 7 are arranged in a pairwise symmetric form. On both sides of the bottom frame of the braking frame 2, first guide rail frames B10 that are in guiding adaptation with the first telescopic hinge frames 7 are arranged in a pairwise symmetric form. Based on the first guide rail frames on the bottom support frame 1 and the braking frame 2 as the extension slide rails of the first telescopic hinge frames 7, the first telescopic hinge frames 7 are kept in a stable and firm state during extension and contraction, improving the lifting stability of the lifting platform.

[0026] The braking frame 2 and the top support frame 3 are connected by second telescopic hinge frames 8 arranged in a pairwise symmetric arrangement. On both sides of the top frames of the braking frame 2, second guide rail frames A11 that are in guiding adaptation with the second telescopic hinge frames 8 are arranged in a pairwise symmetric form. On both sides of the frames of the top support frame 3, second guide rail frames B12 that are in guiding adaptation with the second telescopic hinge frames 8 are arranged in a pairwise symmetric form. Based on the second guide rail frames on the braking frame 2 and the top support frame 3 as the extension slide rails of the second telescopic hinge frames 8, the second telescopic hinge frames 8 are kept in a stable and firm state during extension and contraction, improving the lifting stability of the lifting platform.

[0027] Inside the frame of the brake frame 2, a braking mechanism 13 for driving the first telescopic jib 7 and the second telescopic jib 8 is provided. At the upper end of the frame of the top support frame 3, a workbench 4 is installed. The braking mechanism 13 includes a braking lead screw 131 rotatably connected to the middle of the frame of the brake frame 2 and a braking motor 132 installed on the brake frame 2 along the axial direction of the braking lead screw 131. And between the braking motor 132 and the braking lead screw 131, they are drivingly connected through a transmission belt 133. On the outer side of the shaft of the braking lead screw 131, two groups of guiding sliders 137 are symmetrically sleeved. On both sides of the frames of the two groups of guiding sliders 137, arm force struts 134 are symmetrically arranged. And at the top of the arm of each group of arm force struts 134, a fixed shaft seat 135 is connected. Inside the support of the fixed shaft seat 135, an arm force support rod 136 connected to the first telescopic jib 7 and the second telescopic jib 8 is installed through. Taking the midline as the boundary, on both sides of the midline of the braking lead screw 131, positive and reverse threads adapted to the two groups of guiding sliders 137 are symmetrically arranged. By controlling the operation of the braking motor 132 and using the intermediate transmission of the transmission belt 133, the braking lead screw 131 is driven to rotate. By using the combined transmission of the positive and reverse threads on its shaft, the two groups of guiding sliders 137 are pushed to slide symmetrically along its shaft direction. Then the arm force struts 134 are driven to rotate symmetrically, converting the vertical braking force into a horizontal braking force. Through the combination of the fixed shaft seat 135 and the arm force support rod 136, the first telescopic jib 7 and the second telescopic jib 8 are driven to synchronously expand and contract and rotate, so that the combination of the bottom support frame 1, the brake frame 2, and the top support frame 3 expands and lifts at equal intervals, pushing the workbench 4 to lift and displace, providing a stable high-altitude work platform.

[0028] The working principle of the present utility model is as follows: When using the lifting platform as a high-altitude work platform for workers, based on the support casters 5, the lifting platform is pushed to the designated position. Then, according to the on-site environment, the telescopic guide rail 16 is pulled out from the guide rail frame 15 by an appropriate length, and the support foot seat 6 extends outward by an appropriate length to ensure the stability of the vertical placement center of gravity of the lifting platform. Then, based on the telescopic braking of the lifting electric push rod 14, the support foot seat 6 is pushed downward to contact the ground, replacing the support casters 5 to perform fixed-point support on the lifting platform, and stably fixing the vertical placement support of the lifting platform.

[0029] Further, after the staff member steps onto the workbench 4, control the braking motor 132 to work, and drive the braking lead screw 131 to rotate by means of the intermediate transmission of the transmission belt 133. Utilize the positive and reverse thread transmission combination on its shaft to push the two groups of guiding sliders 137 to slide symmetrically along the direction of its shaft, and then drive the arm force struts 134 to rotate symmetrically, converting the vertical braking force into a horizontal braking force. Through the combination of the fixed shaft seat 135 and the arm force support rod 136, drive the first telescopic bracket 7 and the second telescopic bracket 8 to synchronously expand and rotate along the corresponding guide rail brackets, and push the combination of the bottom support frame 1, the braking frame 2, and the top support frame 3 to lift and expand at equal intervals. Then, push the workbench 4 to lift and displace, and smoothly lift and displace the workbench 4 for high-altitude operation work.

[0030] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and defined, are implemented according to the conventional means in this field.
