Technical Field

[0001] The utility model relates to the technical field of electric power maintenance, in particular to an electric power maintenance workbench. Background Art

[0002] Electricity is indispensable in modern life and industrial production. To ensure the normal operation of power equipment, power maintenance personnel need to inspect the power equipment on time and repair any problems found in time to ensure stable power transmission. During power maintenance, some power equipment is installed at high places. Power maintenance personnel usually use a work platform with a lifting function to perform high-altitude maintenance work, and usually use a scissor lift to operate the work platform.

[0003] When the existing power maintenance workbench is in use, the workbench can be raised and lowered by the action of a scissor lift. However, in actual operation, there is usually a safety operator at the bottom to operate, but the operator on the workbench cannot adjust the height of the working step by himself, and thus cannot adjust the appropriate operating height by himself. For this reason, we propose an power maintenance workbench. Utility Model Content

[0025] The working principle of the above technical solution is as follows:

[0026] During use, the fine-tuning lifting mechanism 7 is moved to drive the movable mounting block 6 to move inside the fixed limit guide groove 5 for lateral adjustment, and then the fine-tuning lifting mechanism 7 is controlled by the switch adjustment button 9, and then the height is fine-tuned by the fine-tuning lifting mechanism 7, so that maintenance personnel can perform maintenance on the electricity stably and the operation is convenient.

[0027] In another embodiment, Figure 3 As shown, a fixed protection mechanism 10 is fixedly connected to one side of the fixed mounting seat 8 .

[0028] The fixing protection mechanism 10 can protect the switch adjustment button 9 when the switch adjustment button 9 is not adjusted, thereby avoiding accidental touch during operation, and the operation is convenient.

[0029] In another embodiment, Figure 2 As shown, the fine-tuning lifting mechanism 7 includes two mounting plates 11. The lower mounting plate 11 and the movable mounting block 6 are connected and fixed to each other. A lifting and folding frame 13 is provided between the two mounting plates 11. The ends of the lifting and folding frames 13 close to each other are symmetrically provided with fixed connecting rods 14. A fixed frame 15 is fixedly sleeved on the surface of one of the fixed connecting rods 14. A servo motor 16 is fixedly connected to one side of the fixed frame 15. A rotating threaded rod 17 is fixedly connected to the output end of the servo motor 16. A threaded sleeve rod 18 is fixedly connected to the outer surface of the other fixed connecting rod 14. The threaded sleeve rod 18 and the rotating threaded rod 17 are connected by threads.

[0030] The servo motor 16 can drive the rotating threaded rod 17 so that the threaded sleeve 18 can move outside the surface of the rotating threaded rod 17, adjust the end distance of the lifting and folding frame 13, and then make the lifting and folding frame 13 fold and deflect, and then adjust the distance between the mounting plates 11, which is easy to operate.

[0031] In another embodiment, Figure 1 and Figure 2 As shown, the outer surface of the movable installation block 6 and the inner surface of the fixed limiting guide groove 5 are slidably fitted with each other.

[0032] The movable mounting block 6 can stably move inside the fixed limiting guide groove 5 , and the operation is convenient.

[0033] In another embodiment, Figure 4As shown, the fixed protective mechanism 10 includes a connecting sleeve block 19, the interior of the connecting sleeve block 19 is movably connected to a movable connecting rod 20, the bottom end of the movable connecting rod 20 is fixedly connected to a mounting chassis 21, a force spring 22 is fixedly connected between the top of the mounting chassis 21 and the inner top of the connecting sleeve block 19, the top of the movable connecting rod 20 is fixedly connected to a connecting top block 23, and the top of one side of the connecting top block 23 is fixedly connected to a connecting protective cover 24.

[0034] It is convenient to install the chassis 21, which can limit the position of the movable connecting rod 20 when it is acted upon by the force spring 22, thereby limiting the position of the connecting top block 23 and the connecting protective cover 24, so that the connecting protective cover 24 can stably cooperate with the top of the fixed mounting seat 8, protect the switch adjustment button 9, avoid accidental touch, and facilitate operation.

[0035] In another embodiment, Figure 4 As shown, the bottom end of the connecting protective cover 24 and the top of the fixed mounting seat 8 are fitted together.

[0036] The protective cover 24 can be stably connected to the top of the fixed mounting seat 8 to cover and protect the switch adjustment button 9 to avoid accidental touch, which is convenient for operation.

[0037] In another embodiment, Figure 4 As shown, a connecting handle 25 is fixedly connected to the side of the connecting top block 23 away from the movable connecting rod 20 .

[0038] It is convenient to lift the connecting handle 25, which can quickly drive the connecting top block 23, the connecting protective cover 24, the movable connecting rod 20 and the mounting chassis 21 to move, compressing the force spring 22, thereby quickly adjusting and convenient operation.

[0039] The working principle of the present invention is as follows: during use, the operator can adjust the lateral movement of the fine-tuning lifting mechanism 7 as a whole, so that the connecting roller 12 can move on the top of the platform body 1, and at the same time drive the movable mounting block 6 to move inside the fixed limiting guide groove 5. After the lateral adjustment is completed, the operator can be on the top of the mounting plate 11 and pull the connecting handle 25 upward to drive the connecting top block 23, the connecting protective cover 24, the movable connecting rod 20 and the mounting chassis 21 to move upward, compressing the force spring 22, so that the connecting protective cover 24 and the top of the fixed mounting seat 8 are separated from each other, and the switch adjustment button 9 is pressed and adjusted so that the servo motor 1 6 can drive the rotating threaded rod 17, and the threaded sleeve rod 18 moves outside the surface of the rotating threaded rod 17, so that the lifting and folding frame 13 is deflected and folded, and the distance between the mounting plates 11 is adjusted, thereby fine-tuning the height, which is convenient for the operator to inspect and repair the electricity. After the adjustment is completed, the connecting handle 25 is released, and the mounting chassis 21 is acted upon by the force spring 22 to drive the movable connecting rod 20, the connecting top block 23 and the connecting protective cover 24 to move downward, so that the connecting protective cover 24 and the top of the fixed mounting seat 8 are fitted with each other, thereby covering and protecting the switch adjustment button 9 to avoid accidental touch, thereby improving the safety of use, and the overall structure is simple and easy to operate.

[0040] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
