Description

Technical Field

[0001] This utility model relates to the field of support equipment technology, specifically to a power support device for power installation. Background Technology

[0002] During power construction, it is often necessary to install various electrical equipment at high positions or to dismantle or replace electrical equipment at heights. Since electrical equipment is often heavy, manual lifting is not only labor-intensive but also dangerous. Existing power installation support devices may sway during the lifting process, affecting work efficiency and potentially creating safety hazards.

[0003] Therefore, we propose a power support device for power installation. Utility Model Content

One end of the second chain is fixedly installed to the top of the counterweight block, and the other end of the second chain is fixedly installed to the top of the connecting frame.

[0006] Optionally, a synchronous pulley is fixedly installed at the same end of the two rotating shafts, and the two synchronous pulleys are connected by a synchronous belt drive. The output end of the drive motor is fixedly installed at one end of one of the rotating shafts.

[0007] Optionally, the counterweight is a cylinder with a diameter smaller than the inner diameter of the fixed cylinder, and anti-collision rollers are provided at the top and bottom of the counterweight, and the anti-collision rollers are in rolling connection with the inner wall of the fixed cylinder.

[0008] Optionally, the sliding frame is fixedly installed at the four corners of one side of the connecting frame, and two symmetrical rolling wheels are rotatably connected to the middle of the sliding frame. The sliding frame is rotatably connected to a clamping wheel located between the two rolling wheels.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This power support device for power installation, by setting a first chain and a second chain, drives a motor to make two rotating shafts and a lower sprocket rotate synchronously through a synchronous belt and a synchronous pulley, thereby causing the first chain to rotate, pulling the counterweight or connecting frame down, and then causing the second chain to rotate in coordination with the first chain. The connecting frame moves smoothly up or down along the guide rail, so that the telescopic placement plate can be raised and lowered smoothly when the power equipment is in use, improving the stability of the support and saving manpower.

[0014] 2. The power support device for power installation is equipped with anti-collision rollers to prevent the counterweight from colliding with the inside of the fixed cylinder during movement, thereby further ensuring the stability of the lifting.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a power support device for power installation, including a movable base 1, with movable wheels 16 at the bottom of the movable base 1, a drive motor 2 fixedly installed inside the movable base 1, fixed cylinders 3 fixedly installed on both sides of the top of the movable base 1, a rotating shaft 4 rotatably connected to the bottom of the fixed cylinders 3 and located inside the movable base 1, guide rails 9 fixedly installed on the front and rear sides of the fixed cylinders 3, an upper sprocket 13 rotatably connected to the top of the fixed cylinders 3, one end of the rotating shaft 4 fixedly installed to the output end of the drive motor 2, a lower sprocket 7 fixedly installed inside the fixed cylinders 3 and driven by a first chain 8, a counterweight 15 fixedly installed inside the fixed cylinders 3 at one end of the first chain 8, and a connecting frame 11 fixedly installed at the other end of the first chain 8, with fixed mounting brackets 11 on both sides of the connecting frame 11. Equipped with a sliding frame 10, which is slidably connected to a guide rail 9, a retractable placement plate 12 is provided in the middle of a connecting frame 11. A second chain 14 is driven by an upper sprocket 13. One end of the second chain 14 is fixedly installed on the top of a counterweight 15, and the other end of the second chain 14 is fixedly installed on the top of the connecting frame 11. By setting a first chain 8 and a second chain 14, the drive motor 2 causes the two rotating shafts 4 and the lower sprocket 7 to rotate synchronously through a synchronous belt 6 and a synchronous pulley 5, thereby causing the first chain 8 to rotate and pull the counterweight 15 or the connecting frame 11 to move down. This causes the second chain 14 to rotate in coordination with the first chain 8. The connecting frame 11 moves smoothly up or down along the guide rail 9, so that the retractable placement plate 12 can be raised and lowered smoothly when using electrical equipment, improving the stability of the lifting and saving manpower.

[0022] Synchronous pulleys 5 are fixedly installed at the same end of two rotating shafts 4. The two synchronous pulleys 5 are connected by a synchronous belt 6. The output end of the drive motor 2 is fixedly installed at one end of one rotating shaft 4. The counterweight 15 is a cylinder with a diameter smaller than the inner diameter of the fixed cylinder 3. Anti-collision rollers 17 are provided at the top and bottom of the counterweight 15. The anti-collision rollers 17 are rolled in contact with the inner wall of the fixed cylinder 3. By setting the anti-collision rollers 17, the counterweight 15 is prevented from colliding with the inside of the fixed cylinder 3 during movement, further ensuring the stability of the lifting. The sliding frame 10 is fixedly installed at the four corners of one side of the connecting frame 11. Two symmetrical rolling wheels 18 are rotatably connected to the middle of the sliding frame 10. A clamping wheel 19 is located between two rolling wheels 18. The rolling wheels 18 and the clamping wheel are respectively connected to the three sides of the guide rail 9 in a rolling contact. The two guide rails 9 are symmetrically installed on the front and rear sides of the fixed cylinder 3. A buffer pad is provided on the top of the guide rail 9. The rolling wheels 18 and the clamping wheel 19 can ensure that the sliding frame 10 slides smoothly with the guide rail 9, so as to ensure the stability of the connecting frame 11 and the placement plate 12 during use. The first chain 8 and the second chain 14 have the same length. The upper sprocket 13 and the lower sprocket 7 have the same size. The four moving wheels 16 are fixedly installed at the four corners of the bottom of the moving base 1. The moving wheels 16 are universal wheels with a brake locking mechanism.

[0023] Working principle:

[0024] The drive motor 2 drives the two shafts 4 and the lower sprocket 7 to rotate synchronously via the synchronous belt 6 and the synchronous pulley 5. This causes the first chain 8 to rotate, pulling the counterweight 15 or the connecting frame 11 downward. Consequently, the second chain 14 rotates in coordination with the first chain 8. The connecting frame 11 moves smoothly up or down along the guide rail 9, allowing the retractable placement plate 12 to rise and fall smoothly when in use with electrical equipment. This improves the stability of the lifting and saves manpower. By setting anti-collision rollers 17, the counterweight 15 is prevented from colliding with the inside of the fixed cylinder 3 during movement, further ensuring the stability of the lifting. The rolling wheels 18 and the clamping wheels 19 ensure that the sliding frame 10 slides smoothly with the guide rail 9, thus ensuring the stability of the connecting frame 11 and the placement plate 12 during use.
