Description

Technical Field

[0001] This utility model belongs to the field of power distribution equipment technology, and specifically relates to a lifting device. Background Technology

[0002] Power distribution equipment refers to equipment used for power distribution and control, typically including transformers, circuit breakers, switch cabinets, distribution boxes, etc. These devices play a key role in the power system, ensuring that power can be safely and efficiently transmitted to various power consumption points. Currently, power distribution equipment requires the use of specialized lifting devices during operation.

[0003] Existing lifting devices typically use hydraulic telescopic rods to move the lifting frame upwards to lift the power distribution equipment. While this lifting method is effective, it lacks flexibility and adaptability when dealing with power distribution equipment of different specifications and sizes. It is difficult to quickly adapt to equipment of different sizes and lacks an effective protective structure. As a result, the power distribution equipment is not stable enough during transportation, and it is prone to tipping or tilting, which increases safety hazards and reduces work efficiency. Utility Model Content

[0004] In view of this, the present invention provides a lifting device that can adapt to the lifting needs of power distribution equipment of different sizes through the coordinated cooperation of the lifting mechanism and the limiting component, ensuring the stability and safety of the power distribution equipment during transportation, effectively preventing the equipment from tipping over or tilting, and improving the reliability and efficiency of operation.

[0005] To solve the above-mentioned technical problems, this utility model provides a lifting device, including a frame and a lifting mechanism disposed at the lower end of the frame. The lifting mechanism is characterized in that: the lifting mechanism is used to lift power distribution equipment, and includes a lifting frame slidably connected to one side of the frame. A guide rail groove is provided on the side of the lifting frame away from the frame. Sliding plates are slidably connected to both ends of the inner cavity of the guide rail groove. A bidirectional lead screw is rotatably connected between the two ends of the inner cavity of the guide rail groove. The two ends of the bidirectional lead screw are respectively threaded to threaded holes in the middle of adjacent sliding plates on the same side. The upper end of the frame is also provided with a limiting component for limiting the movement of the power distribution equipment. This adapts to the lifting needs of power distribution equipment of different sizes, ensuring the stability and safety of the power distribution equipment during transportation, effectively preventing the equipment from tipping over or tilting, and improving the reliability and efficiency of operation.

[0006] The lifting mechanism also includes a bevel gear one located on the outside of the double-acting screw near the center of the frame, and a bevel gear two rotatably connected to the upper middle part of the guide rail groove. The bevel gear two meshes with the bevel gear one, thus providing a fast drive function.

[0007] The lifting mechanism also includes a motor located in the middle of the lifting frame. The output shaft of the motor is fixedly connected to the second bevel gear, which provides a drive source for the second bevel gear.

[0008] The lifting mechanism also includes a hydraulic telescopic rod located at the bottom of the frame. The telescopic end of the hydraulic telescopic rod is fixedly connected to the upper end of the lifting frame, thereby enabling the lifting operation of the power distribution equipment.

[0009] The limiting component includes guide grooves on the upper ends of both sides of the frame, a sliding frame slidably connected between the two guide grooves, the sliding frame being fixedly connected to the upper end of the lifting frame, and limiting swing plates rotatably connected to both ends of the inner cavity of the sliding frame. Limiting tooth plates are provided on the opposite inner sides of the two limiting swing plates, which effectively prevents the equipment from tipping over or tilting.

[0010] The limiting assembly also includes a mounting port located at the end of the sliding frame away from the frame. An electric telescopic rod is rotatably connected to the inner cavity of the mounting port near the frame. Mounting seats are provided on opposite outer sides of the two limiting swing plates. The mounting seats are rotatably connected to the telescopic ends of the adjacent electric telescopic rods on the same side, thus providing a driving source for the limiting swing plates and their auxiliary mechanisms.

[0011] The limit tooth plate is a limit ratchet plate, which ensures the limiting effect on the power distribution equipment.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. Move the lifting device next to the power distribution equipment that needs to be transferred, and position the lifting frame at the bottom of the power distribution equipment. Then, start the motor, and its output shaft rotates, driving the second bevel gear to rotate synchronously. When the second bevel gear rotates, it drives the double-acting screw to rotate through the bevel gear first that meshes with it. Due to the influence of the threaded connection between the double-acting screw and the screw hole, the double-acting screw drives the sliding plate to move along the guide rail groove to both sides or towards its center when it rotates, so as to adapt to the lifting needs of power distribution equipment of different sizes. Finally, the extension end of the hydraulic telescopic rod moves upward, driving the lifting frame and the sliding frame to move upward synchronously, thereby realizing the lifting operation of the power distribution equipment.

[0014] 2. The telescopic end of the electric telescopic rod extends and pushes the limiting swing plate inward through the mounting seat, so that the limiting tooth plate on the limiting swing plate contacts the power distribution equipment. The tooth groove of the limiting swing plate cooperates with the edge of the power distribution equipment to achieve the limiting and fixing of the power distribution equipment, ensuring the stability and safety of the power distribution equipment during transportation, effectively preventing the equipment from tipping over or tilting, and improving the reliability and efficiency of operation.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] This embodiment provides a lifting device, such as Figure 1-4 As shown: It includes a frame 100 and a lifting mechanism disposed at the lower end of the frame 100. The lifting mechanism is used to lift the power distribution equipment. The lifting mechanism includes a lifting frame 200 slidably connected to one side of the frame 100. The side of the lifting frame 200 away from the frame 100 is provided with a guide rail groove 201. Both ends of the inner cavity of the guide rail groove 201 are slidably connected with sliding plates 202. A bidirectional lead screw 203 is rotatably connected between the two ends of the inner cavity of the guide rail groove 201. The two ends of the bidirectional lead screw 203 are respectively threadedly connected to the threaded holes provided in the middle of the adjacent sliding plates 202 on the same side. The upper end of the frame 100 is also provided with a limiting component for limiting the power distribution equipment.

[0022] The lifting device is moved next to the power distribution equipment to be transferred, and the lifting frame 200 is positioned at the bottom of the power distribution equipment. Then, the sliding plate 202 is driven to move along the guide rail groove 201 to both sides or towards its center, thereby adapting to the lifting needs of power distribution equipment of different sizes. At the same time, the power distribution equipment is limited by the limiting component, thereby achieving the limiting and fixing of the power distribution equipment, ensuring the stability and safety of the power distribution equipment during transportation, effectively preventing the equipment from tipping over or tilting, and improving the reliability and efficiency of operation.

[0023] like Figure 2-3As shown, the lifting mechanism also includes a bevel gear 204 located outside the bidirectional lead screw 203 near the center of the frame 100. A bevel gear 205 is rotatably connected to the upper middle part of the guide rail groove 201. The bevel gear 205 meshes with the bevel gear 204. When the bevel gear 205 rotates, it drives the bidirectional lead screw 203 to rotate through the bevel gear 204 meshing with it, thus achieving a rapid driving effect.

[0024] like Figure 2-3 As shown, the lifting mechanism also includes a motor 206 located in the middle of the lifting frame 200. The output shaft of the motor 206 is fixedly connected to the second bevel gear 205. The rotation of the output shaft of the motor 206 drives the second bevel gear 205 to rotate synchronously, thereby providing a driving source for the second bevel gear 205.

[0025] like Figure 1-3 As shown, the lifting mechanism also includes a hydraulic telescopic rod 207 disposed at the bottom of the frame 100, and the telescopic end of the hydraulic telescopic rod 207 is fixedly connected to the upper end of the lifting frame 200.

[0026] The upward movement of the extension end of the hydraulic telescopic rod 207 causes the lifting frame 200 and the sliding frame 301 to move upward synchronously, thereby realizing the lifting operation of the power distribution equipment.

[0027] like Figure 1-4 As shown, the limiting component includes guide grooves 300 disposed on the upper ends of both sides of the frame 100, a sliding frame 301 slidably connected between the two guide grooves 300, the sliding frame 301 being fixedly connected to the upper end of the lifting frame 200, and limiting swing plates 302 being rotatably connected to both ends of the inner cavity of the sliding frame 301, and limiting tooth plates 303 being provided on the opposite inner surfaces of the two limiting swing plates 302.

[0028] The mounting base 306 pushes the limiting swing plate 302 to swing inward, thereby causing the limiting tooth plate 303 on the limiting swing plate 302 to contact the power distribution equipment. The tooth grooves of the limiting tooth plate 303 cooperate with the edges of the power distribution equipment to achieve limiting and fixing of the power distribution equipment, ensuring the stability and safety of the power distribution equipment during transportation, effectively preventing the equipment from tipping over or tilting, and improving the reliability and efficiency of operation.

[0029] like Figure 1-4 As shown, the limiting assembly also includes a mounting port 304 located at the end of the sliding frame 301 away from the frame 100. An electric telescopic rod 305 is rotatably connected to the end of the mounting port 304 near the frame 100. Mounting seats 306 are provided on the opposite outer sides of the two limiting swing plates 302. The mounting seats 306 are rotatably connected to the telescopic ends of the adjacent electric telescopic rods 305 on the same side.

[0030] The telescopic end of the electric telescopic rod 305 extends out and pushes the limiting swing plate 302 to swing inward through the mounting base 306, providing a driving source for the limiting swing plate 302 and its auxiliary mechanisms.

[0031] like Figure 1-2 As shown, the limiting tooth plate 303 is a limiting ratchet plate. The ratchet groove of the limiting ratchet plate cooperates with the edges of the power distribution equipment to ensure the limiting effect on the power distribution equipment.

[0032] The working principle of the lifting device provided by this utility model is as follows: First, the lifting device is moved next to the power distribution equipment that needs to be transferred, and the lifting frame 200 is placed at the bottom of the power distribution equipment. Then, the motor 206 is started, and its output shaft rotates, driving the second bevel gear 205 to rotate synchronously. When the second bevel gear 205 rotates, it drives the double-acting lead screw 203 to rotate through the bevel gear 204 that meshes with it. Due to the influence of the threaded connection between the double-acting lead screw 203 and the threaded hole, when the double-acting lead screw 203 rotates, it drives the sliding plate 202 to move along the guide rail groove 201 to both sides or towards its center, thereby adapting to power distribution equipment of different sizes. To meet the equipment lifting requirements, the electric telescopic rod 305 extends its telescopic end and pushes the limiting swing plate 302 inward through the mounting base 306, thereby causing the limiting tooth plate 303 on the limiting swing plate 302 to contact the power distribution equipment. The tooth grooves of the limiting tooth plate 303 engage with the edges of the power distribution equipment to achieve limiting and fixing of the power distribution equipment, ensuring the stability and safety of the power distribution equipment during transportation, effectively preventing the equipment from tipping over or tilting, and improving the reliability and efficiency of operation. Finally, the telescopic end of the hydraulic telescopic rod 207 moves upward, causing the lifting frame 200 and the sliding frame 301 to move upward synchronously, thereby realizing the lifting operation of the power distribution equipment.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
