Therefore, timely maintenance and servicing of electromechanical equipment is crucial to reduce the occurrence of failures and ensure the normal operation of highways. Usually, staff are required to regularly maintain and repair the electromechanical systems of highways. Since some electromechanical systems such as monitoring systems and lighting systems are installed at higher locations, lifting frames are required when repairing some electromechanical systems.

[0003] The existing highway electromechanical maintenance auxiliary lifting frame is usually composed of a motor, a lifting platform, a spiral lifting mechanism and other parts. This mechanism consists of a spiral rod and a nut. By starting the motor to drive the spiral rod to rotate, the nut moves up and down along the spiral rod, and the spiral lifting mechanism rotates, thereby making the lifting platform rise or fall, to operate and realize the lifting function.

[0004] The existing lifting frame has a single structure and uses a screw to drive the platform to rise and fall. Under a large load, the connection between the screw and the platform is subjected to a large force, which will cause instability for a long time. Therefore, a highway electromechanical maintenance auxiliary lifting frame is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 2 The utility model provides an embodiment: an auxiliary lifting frame for electromechanical maintenance of a highway, including a lifting shell 2, a foot pad 1 is fixedly connected to the lower surface of the lifting shell 2, a lifting strip 3 is slidably connected inside the lifting shell 2, a lifting platform 4 is fixedly connected to the upper surface of the lifting strip 3, an auxiliary component is arranged on the upper surface of the lifting platform 4, a base 10 is fixedly connected between the lifting shells 2, a protective shell 6 is fixedly connected to the upper surface of the base 10, a rotating column 7 is rotatably connected inside the protective shell 6, a worm wheel 8 is fixedly connected to the side wall of the rotating column 7, a worm 9 is rotatably connected inside the base 10, and the worm 9 and the worm wheel 8 The motor 11 is meshed with each other, and the output end of the motor 11 is fixedly connected to the side wall of the worm 9. The upper surface of the base 10 is fixedly connected to the fixed seat 12. The side wall of the rotating column 17 is rotatably connected to the inside of the fixed seat 12. The side wall of the rotating column 17 passes through the fixed seat 12 and is fixedly connected to the rotating column 2 13. The side wall of the rotating column 2 13 is fixedly connected to the connecting plate 14. The inside of the connecting plate 14 is slidably connected to the fixing column 15. The side wall of the fixing column 15 is fixedly connected to the inside of the lifting strip 3. The auxiliary components include a protective column 5, and the lower surface of the protective column 5 is fixedly connected to the upper surface of the lifting platform 4.

[0033] When using the equipment to perform electromechanical maintenance work on highways, the staff stands on the surface of the lifting platform 4, ready to perform maintenance and repair work. In order to increase the height of the lifting platform 4, the staff starts the motor 11, drives the worm 9 to rotate, and the worm 9 meshes with the worm wheel 8, so the worm wheel 8 also starts to rotate. The movement of the worm wheel 8 is not just a simple rotation, it also drives the rotation of the rotating column 17. This movement acts on the rotating column 2 13, which in turn causes the fixed column 15 to slide inside the connecting plate 14, so that the lifting bar 3 starts to push up and slides upward inside the lifting shell 2. This process changes the height of the lifting platform 4, allowing the staff to operate at the required height. When it is necessary to lower the height of the lifting platform 4, the motor 11 is reversed to rotate the worm 9 in the opposite direction. This movement in turn causes the fixed column 15 to drive the lifting bar 3 downward during the sliding process inside the connecting plate 14, so that the lifting platform 4 slides downward inside the lifting shell 2. Through the operation of the above equipment, the staff can easily adjust the height of the lifting platform 4 to adapt to maintenance work with different height requirements, providing a safe and reliable working platform for the staff.

[0034] Reference Figure 3-Figure 4 A storage box 16 is fixedly connected to the lower surface of the lifting platform 4, and a fixed block 17 is fixedly connected to the side wall of the storage box 16. A fixed column 18 is rotatably connected to the side wall of the fixed block 17. A hydraulic rod 19 is fixedly connected to the side wall of the fixed column 18. A connecting column 20 is fixedly connected to the output end of the hydraulic rod 19. A fixed plate 21 is rotatably connected to the side wall of the connecting column 20. A rotating column 3 22 is fixedly connected to one side of the fixed plate 21. One end of the rotating column 3 22 is rotatably connected to the side wall of the fixed block 17. A connecting plate 23 is fixedly connected to the side wall of the rotating column 3 22. A connecting plate 3 24 is rotatably connected to the side wall of the fixed block 17. A platform 25 is rotatably connected between the connecting plates 3 24, and one side of the connecting plate 23 is rotatably connected to the side wall of the platform 25.

[0035] When the staff needs to get off the lifting platform 4, they can start the hydraulic rod 19. The contraction movement of the hydraulic rod 19 causes the connecting column 20 to move upward. The movement of the connecting column 20 causes the fixed plate 21 to drive the rotating column three 22 to rotate. This action causes the connecting plate two 23 and the connecting plate three 24 to move downward. At the same time, this also drives the platform 25 to move downward. The effect of this movement is to create a step that is convenient for the staff to go up and down, providing a convenient and safe path for the staff, so that they can easily get off the lifting platform 4 and continue to carry out maintenance work, ensuring safety and efficiency during the operation.

[0036] Working principle: When using the equipment to carry out electromechanical maintenance work on highways, the staff stands on the upper surface of the lifting platform 4. When the height of the lifting platform 4 needs to be increased, the motor 11 is started to drive the worm 9 to rotate. Since the worm wheel 8 is meshed with the worm 9, the worm wheel 8 will also rotate, and at the same time drive the rotating column 7 to rotate, so that the rotating column 2 13 rotates, so that the fixed column 15 pushes the lifting bar 3 upward during the sliding process inside the connecting plate 14, so that it slides upward inside the lifting shell 2, thereby achieving the effect of lifting the lifting platform 4 upward to change the height. When the height needs to be lowered, the motor 11 is started to drive the worm 9 to rotate in the reverse direction, so that the fixed column 15 drives the lifting bar 3 downward during the sliding process inside the connecting plate 14, so that it slides downward inside the lifting shell 2, thereby achieving the effect of lowering the height of the lifting platform 4. When the staff needs to get off the lifting platform 4, the hydraulic rod 19 is started to shrink, driving the connecting column 20 to move upward, so that the fixed plate 21 drives the rotating column three 22 to rotate, so that the connecting plate two 23 and the connecting plate three 24 move downward, and at the same time drive the platform 25 to move, so as to achieve the effect of a step that is convenient for the staff to go up and down.
