Description

Technical Field

This includes testing, cleaning, repairing and replacing parts of power equipment such as generators, transformers, switchgear, cable lines, etc., to ensure the safe and reliable operation of the power system, extend the service life of the equipment, and improve the quality of power supply. During the power operation and maintenance process, it is often necessary to perform high-altitude operations or high-altitude maintenance of equipment, and then a lifting device is needed. The lifting device can provide workers with a safe and stable high-altitude working environment, allowing them to easily reach the height where the equipment is located to perform maintenance and repair work.

[0003] When an existing electric power operation and maintenance lifting device is in use, the electric power device is placed on the top surface of the rising plate, and then the rotating columns arranged on the side frames on both sides of the bottom plate are rotated. The rotating columns can rotate on the side frames through the first bearing and the second bearing arranged on the side frames. When the rotating column rotates, the rotating column drives one end of the traction rope arranged on the rotating column to rotate, and one end of the traction rope is wound around the rotating column. At this time, the lifting plate slowly rises, thereby achieving the effect of lifting and repairing the electric power device.

[0004] However, this method cannot play a buffering role for the lifting plate when used. Long-term use of a lifting device that lacks a buffering effect will cause damage to the equipment itself, shorten the service life of the equipment, and increase the frequency and cost of replacing the equipment. The lack of a buffering effect will cause the lifting device to produce a greater impact force, which will cause damage to the lifting device itself and related equipment, leading to equipment repair and replacement, and increased maintenance costs.

[0023] 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.

[0024] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: an electric power operation and maintenance lifting device, comprising a bottom plate 1 and a vertical plate 21, both sides of the upper part of the bottom plate 1 are fixedly connected with positioning plates 13, the opposite sides of the two positioning plates 13 are fixedly connected with limit rods 12, the outer sides of the limit rods 12 are slidably connected with limit blocks 11, the upper parts of the two limit blocks 11 are rotatably connected with adjustment rods 10, the upper parts of the two adjustment rods 10 are rotatably connected with lifting plates 9, the upper parts of the bottom plate 1 are fixedly connected with dampers 15, and the two dampers The upper part of 15 is fixedly connected with the lifting plate 9, the two sides of the bottom plate 1 are fixedly connected with the mounting seat 16, the interior of the mounting seat 16 is provided with a fixing component, the fixing component includes a screw 18, the screw 18 is threadedly connected to the interior of the mounting seat 16, the upper part of the screw 18 is fixedly connected with the turning handle 17, the bottom of the screw 18 is threadedly connected with the fixing seat 19, the outer sleeve of the limiting rod 12 is provided with a buffer spring 14, one end of the buffer spring 14 is fixedly connected with the positioning plate 13, and the other end of the buffer spring 14 is fixedly connected with the limiting block 11.

[0025] When the lifting plate 9 starts to move under the action of the driving force, the adjusting rod 10 connected thereto will also be displaced accordingly. During the movement, the adjusting rod 10 is closely connected with the limit block 11. As the adjusting rod 10 moves, the limit block 11 will slide outside the limit rod 12. The limit rod 12 serves as a sliding track for the limit block 11 to ensure the stability and direction of its movement. During the sliding process of the limit block 11, it will squeeze the buffer spring 14. As an elastic element, the buffer spring 14 has good buffering performance. When the limit block 11 applies pressure to it, the buffer spring 14 will be deformed. Absorb and disperse this part of the impact force. This buffering effect can effectively reduce the impact force generated by the lifting plate 9 when it stops, and protect the lifting device and its surrounding equipment or structures from damage. In addition to the buffer spring 14, the damper 15 also plays an important role. The damper 15 further buffers the movement of the lifting plate 9 through its internal liquid or gas resistance. When the lifting plate 9 moves, the damper 15 will generate a certain resistance to slow down its movement speed, thereby achieving smooth buffering of the lifting plate 9. Through the joint action of the buffer spring 14 and the damper 15, the lifting device can effectively buffer the lifting plate 9.

[0026] Reference Figure 1 , Figure 3 and Figure 4A vertical plate 21 is fixedly connected to one side of the upper part of the bottom plate 1, and a cylinder 2 is fixedly connected to both sides of the right part of the vertical plate 21. A positioning block 3 is fixedly connected to the output end of the cylinder 2. A sprocket 4 is rotatably connected to the inside of the positioning block 3, and a chain 5 is meshedly connected to the outside of the sprocket 4. A lifting plate 9 is fixedly connected to one side of the bottom of the chain 5. Mounting blocks 6 are fixedly connected to both sides of the right part of the lifting plate 9, and a slider 7 is fixedly connected to the right part of the mounting block 6. Slide plates 8 are fixedly connected to both sides of the inside of the vertical plate 21, and the slider 7 is slidably connected to the outside of the slider 8. A placement plate 20 is fixedly connected to the right part of the vertical plate 21, and chain 5 is fixedly connected to both sides of the upper part of the placement plate 20.

[0027] The cylinder 2 is used as a power source to drive the entire lifting process. The positioning block 3 and the sprocket 4 together constitute a transmission mechanism to ensure the smooth lifting movement. The chain 5 connects the sprocket 4 and the mounting block 6 to realize the transmission of force. The mounting block 6 and the slider 7 drive the lifting plate 9 to move up and down to realize the lifting function. During use, the staff first starts the cylinder 2. The output end of the cylinder 2 quickly generates thrust to push the positioning block 3 to move along the preset track. The movement of the positioning block 3 drives the rotation of the sprocket 4. The sprocket 4 rotates inside the positioning block 3. When the sprocket 4 rotates, the chain 5 meshed with it also starts to rotate. The rotation of the chain 5 not only transmits force, but also ensures the continuity and stability of the lifting movement. The other end of the chain 5 is connected to the mounting block 6, so the rotation of the chain 5 drives the movement of the mounting block 6. The movement of the mounting block 6 further drives the slider 7 to slide on the outside of the slider 8. The slider 8 provides a stable motion track for the slider 7 to ensure that the slider 7 will not deviate from the direction during the movement. Under the push of the slider 7, the lifting plate 9 starts to move up and down to realize the lifting function.

[0028] Working principle: When in use, start the cylinder 2, the output end of the cylinder 2 pushes the positioning block 3 to move, the positioning block 3 drives the sprocket 4 to move, the sprocket 4 rotates inside the positioning block 3, and the sprocket 4 rotates to drive the meshing chain 5 to rotate, so that the chain 5 drives the mounting block 6 to move, and the mounting block 6 drives the slider 7 to slide on the outside of the slide 8. Under the action of the slider 7, the lifting plate 9 moves up and down, thereby effectively driving the lifting plate 9 to move up and down, and can quickly and stably drive the lifting plate 9 to move up and down, so that the staff can quickly reach the position where maintenance or overhaul is required, which improves The work efficiency is improved and the maintenance time is shortened. When the lifting plate 9 moves, the adjusting rod 10 is driven to move, so that the adjusting rod 10 drives the limit block 11 to slide outside the limit rod 12. When the limit block 11 slides, the buffer spring 14 is squeezed, and the buffer spring 14 plays a buffering role. At the same time, under the action of the damper 15, the lifting plate 9 can be buffered, thereby achieving effective buffering of the lifting plate 9, being able to absorb and disperse the impact force generated when the lifting plate 9 stops, reducing damage to the lifting device and surrounding equipment or structures, and extending the service life of the equipment and structures.
