These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0030] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0031] In the prior art, the installation, maintenance, and replacement of large power equipment, such as transformers, generators, and switchgear, typically requires specialized handling equipment. By rotating the reel drum on the handling equipment, the lifting rope is wound around the reel, thereby changing the position of the power equipment. However, using a single reel to handle power equipment can easily cause shaking during handling, resulting in poor stability.

[0032] In view of this, the embodiment of the present application sets two winding rollers inside the movable seat and connects the two winding rollers through a rotating shaft, so that the two winding rollers can rotate synchronously, thereby ensuring that the winding rope can be tightened synchronously, avoiding the shaking of the power equipment during the rising process, and thus improving the stability of the power equipment during the transportation process.

[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The movable base in the embodiments of the present application can be a box structure for accommodating the winding assembly. For example, the movable base can be a box structure with an open top or a box structure with a removable top cover. The support frame can be a semi-open structure to accommodate and extract power equipment. For example, the support frame can be a frame structure. The fixed block can be a cube, a rectangular parallelepiped, or other structure, and this embodiment will not be further described here.

[0035] Figure 1 Schematic diagram of the structure of the electric equipment handling device provided in this application Figure 1 .like Figure 1 As shown, the power equipment handling device includes a slide frame 1 and two columns 11, the two columns 11 are arranged at both ends of the slide frame 1, and a movable seat 12 is movably connected to the track of the slide frame 1, and a mounting groove 13 is opened on the top of the movable seat 12, and a winding assembly 2 and a rotating shaft 23 are arranged in the mounting groove 13, and the winding assembly 2 is connected to the load-bearing frame 14 through a winding rope 26, and the winding assembly 2 changes the height of the load-bearing frame 14 by tightening or releasing the winding rope 26; wherein, the winding assembly 2 includes two winding rollers 25, and the winding rope 26 is wound around the winding rollers 25. The two winding rollers 25 are separated by a baffle 21, and the rotating shaft 23 is passed through the baffle 21. A winding roller 25 is respectively sleeved on both ends of the rotating shaft 23, and the rotating shaft 23 rotates to drive the winding roller 25 to rotate to change the height of the load-bearing frame 14.

[0036] That is to say, during the transportation of the power equipment, the slide frame 1 plays a guiding role, the movable seat 12 plays a role in power transmission, and the supporting frame 14 plays a role in carrying the power equipment. The movable seat 12 can move on the track of the slide frame 1, and then the movable seat 12 can drive the supporting frame 14 to move through the winding rope 26, thereby realizing the transportation of the power equipment. By arranging two winding rollers 25 inside the movable seat 12 and connecting the two winding rollers 25 through the rotating shaft 23, the two winding rollers 25 can rotate synchronously, thereby ensuring that the winding rope 26 can be tightened synchronously, avoiding the power equipment from shaking during the rising process, thereby improving the stability of the power equipment during transportation. In addition, by arranging a baffle 21 between the two winding rollers 25, the baffle 21 can effectively separate the winding ropes 26 on different winding rollers 25, thereby ensuring the stability of the power equipment during transportation and avoiding the winding ropes 26 on different winding rollers 25 from being entangled with each other.

[0037] Figure 3 This is a schematic diagram of the structure of the winding assembly and guide assembly of the power equipment handling device provided in this application. Figure 3 The winding assembly 2 and the guide assembly 3 of the electric power equipment handling device will be further described.

[0038] In one possible embodiment, a bearing 22 is provided on the baffle 21. The width of the bearing 22 is greater than the width of the baffle 21. The bearing 22 is sleeved on the rotating shaft 23. A motor 24 is provided on the inner wall of the mounting groove 13. One end of the rotating shaft 23 is connected to the motor 24. The motor 24 drives the rotating shaft 23 to rotate, so that the rotating shaft 23 drives the bearing 22 to rotate synchronously. By providing the bearing 22 in the middle of the baffle 21, the bearing 22 can reduce the friction between the rotating shaft 23 and the baffle 21, thereby extending the service life and ensuring the stability of the winding assembly 2. In addition, that is to say, the bearing 22 can also serve as a support member for supporting the rotating shaft 23. The bearing 22 can effectively support the movement of the rotating shaft 23. The addition of the bearing 22 can improve the load-bearing capacity of the winding assembly 2 and improve the stability and reliability of the winding assembly 2.

[0039] Figure 2 Schematic diagram of the structure of the electric equipment handling device provided in this application Figure 2 The following is combined Figure 2 The slide rail frame 1 of the electric power equipment transport device will be further described.

[0040] In one possible embodiment, wheel grooves 119 are provided on both sides of the slide rail frame 1, and auxiliary grooves 121 are further provided at the lower portion of the wheel grooves 119. The wheel grooves 119 and the auxiliary grooves 121 are used to move the movable seat 12. Two rollers 120 are provided on the outer surface of the movable seat 12 relative to each other. The rollers 120 roll in the wheel grooves 119, and the bottom surface of the movable seat 12 contacts the auxiliary grooves 121, and the bottom surface of the movable seat 12 slides in the auxiliary grooves 121. In other words, the wheel grooves 119 and the auxiliary grooves 121 are arranged in a stepped manner on the slide rail frame 1, and the position of the wheel grooves 119 is higher than that of the auxiliary grooves 121. When the movable seat 12 moves on the slide rail frame 1, the rollers 120 of the movable seat 12 can roll in the wheel grooves 119, and the bottom surface of the movable seat 12 can slide in the auxiliary grooves 121. The wheel grooves 119 provide lateral guidance and support for the movable base 12. When the rollers 120 of the movable base 12 roll within the wheel grooves 119, they prevent the movable base 12 from shifting left or right on the slide rail 1, thereby ensuring stable movement of the power equipment. The auxiliary grooves 121 reduce friction between the bottom surface of the movable base 12 and the slide rail 1, making the movable base 12 slide more smoothly on the slide rail 1, reducing frictional losses and improving movement efficiency.

[0041] Optionally, a driving wheel and a driven wheel are provided on the left and right sides of the movable base 12, respectively. Specifically, the roller 120 located on the left side of the movable base 12 is the driving wheel, and the roller 120 located on the right side of the movable base 12 is the driven wheel. The driving wheel passes through the movable base 12 and is connected to the rotating shaft 23, and the driven wheel is connected to the movable base 12. When the motor 24 drives the rotating shaft 23 to rotate, the rotating shaft 23 can drive the driving wheel to roll on the slide rail frame 1, thereby allowing the driven wheel to roll synchronously with the driving wheel.

[0042] Optionally, both the left and right sides of the movable base 12 are driving wheels. Specifically, the motor 24 mounted on the right inner wall of the mounting groove 13 can be a dual-axis synchronous motor 24, so that the rollers 120 located on the left and right sides of the movable base 12 are both driving wheels. One end of the dual-axis synchronous motor 24 is connected to the rotating shaft 23, and the other end of the dual-axis synchronous motor 24 is connected to the roller 120 on the right side of the movable base 12. When the dual-axis synchronous motor 24 rotates, the rollers 120 located on the left and right sides of the movable base 12 can roll synchronously on the slide rail frame 1, thereby ensuring the stability of the power equipment handling process.

[0043] In one possible embodiment, a plurality of guide assemblies 3 are installed on both sides of the mobile seat 12, the guide assemblies 3 are connected to the support frame 14, the guide assemblies 3 are located on the slide rail frame 1, and one side of the guide assemblies 3 is fixedly connected to the mobile seat 12. The guide assemblies 3 are used to limit the descending height of the support frame 14. In other words, the guide assemblies 3 can move on the support frame 14 along with the mobile seat 12. In addition, one end of the guide assemblies 3 is connected to the mobile seat 12, and the other end is connected to the support frame 14. By arranging a plurality of guide assemblies 3 on both sides of the mobile seat 12 and connecting the mobile seat 12 to the support frame 14 through the guide assemblies 3, the guide assemblies 3 can limit the support frame 14, thereby limiting the lowest height to which the support frame 14 can descend.

[0044] In one possible embodiment, the guide assembly 3 includes a fixed block 31 and a guide rod 33. The bottom surface of the fixed block 31 is in contact with the slide rail frame 1. A through hole 32 is provided on the fixed block 31. The guide rod 33 is passed through the fixed block 31 through the through hole 32. A limit block 34 is also provided at one end of the guide rod 33. The limit block 34 is used to limit the position of the guide rod 33 on the fixed block 31. In other words, the bottom of the fixed block 31 is in contact with the slide rail frame 1 and can play a role of fixing and supporting. The guide rod 33 is passed through the fixed block 31 so that it can move in the vertical direction on the fixed block 31. A limit block 34 is provided at one end of the guide rod 33 to limit the position of the guide rod 33 on the fixed block 31. The guide rod 33 plays a guiding and positioning role in the guide assembly 3, ensuring that the power equipment handling device maintains a stable direction and position during movement.

[0045] Figure 5 This is a schematic diagram of the structure of the carrier frame of the power equipment handling device provided in this application. Figure 5 The carrier frame 14 of the electric power equipment transporting device will be further described.

[0046] In one possible implementation, Figure 5As shown, the carrier frame 14 includes a fixed plate 15, multiple fixed rods 16, and a base plate 17. The fixed plate 15 and base plate 17 are connected by the fixed rods 16. The base plate 17 is used to carry electrical equipment. The base plate 17 has a groove 19, on which a load-bearing plate 112 is located. Multiple hydraulic rods 110 are installed in the groove 19. Each hydraulic rod 110 is fitted with a compression spring 111. The load-bearing plate 112 is connected to the groove 19 via the hydraulic rods 110. In other words, space is left between the fixed plate 15 and base plate 17 for the electrical equipment to be placed on the base plate 17, which is supported by the hydraulic rods 110. The design of the hydraulic rods 110 and compression springs 111 allows the load-bearing plate 112 to adjust in height as the hydraulic rods 110 are adjusted, improving the flexibility and adaptability of the electrical equipment handling device. Furthermore, the support of the multiple hydraulic rods 110 ensures a balanced distribution of load capacity on the load-bearing plate 112, ensuring stability during the handling of the electrical equipment.

[0047] In one possible embodiment, notches 113 are formed on both sides of the bottom plate 17. Limiting plates 115 are provided on the surface of the notches 113. Connecting holes are formed on the inner walls of the notches 113. Connecting rods 114 are provided on the limiting plates 115. Connecting rods 114 are inserted into the connecting holes to achieve a rotatable connection between the limiting plates 115 and the notches 113. In other words, the limiting plates 115 can be rotatably engaged with the bottom surface of the notches 113 via the connecting rods 114, making it easier for workers to place or remove electrical equipment into or from the load-bearing plate 112.

[0048] In one possible embodiment, a plurality of slots 118 are formed on the surface of the notch 113, and a plurality of positioning holes 116 are correspondingly formed on the surface of the limiting plate 115. The slots 118 and the positioning holes 116 are connected by positioning pins 117. In other words, when the limiting plate 115 contacts the surface of the notch 113, the positioning pins 117 can pass through the positioning holes 116 on the surface of the limiting plate 115 and the slots 118 on the surface of the notch 113 to fix the position of the limiting plate 115.

[0049] During the specific implementation process, the limiting plate 115 is first rotated outward, and the staff inserts the electrical equipment from the side of the carrier 14 and places it on the load-bearing plate 112. The limiting plate 115 is then rotated inward until it rests on the wall of the notch 113, and the rotational freedom of the limiting plate 115 is fixed using the positioning pin 117. At this time, the upper surface of the limiting plate 115 is higher than the upper surface of the bottom plate 17, preventing the electrical equipment placed on the load-bearing plate 112 from sliding off the side of the bottom plate 17, thereby improving the stability and safety of the handling process.

[0050] Figure 4 This is a schematic diagram of the structure of the fixing assembly of the electric equipment handling device provided in this application. Figure 4The fixing assembly 4 of the electric power equipment transport device will be further described.

[0051] In one possible embodiment, the top of the fixing plate 15 is provided with a plurality of through holes 18, which are used to connect to the fixing assembly 4, which includes an electric push rod 41, a mounting bracket 42, and a pressing plate 43. Each through hole 18 is provided with an electric push rod 41, one end of which is connected to the mounting bracket 42 and the other end is connected to the pressing plate 43, and the fixing plate 15 is disposed between the mounting bracket 42 and the pressing plate 43. In other words, the electric push rod 41 can be inserted into the through holes 18 at the top of the fixing plate 15, thereby enabling the mounting bracket 42 in the fixing assembly 4 to be located at the top of the fixing plate 15 and the pressing plate 43 to be located at the bottom of the fixing plate 15. When the electric push rod 41 is in operation, it can push the pressing plate 43 toward the bottom plate 17, thereby pressing the electrical equipment to ensure its stability and prevent it from shifting during transportation.

[0052] In one possible embodiment, a rubber pad 44 is provided at the bottom of the pressing plate 43, a plurality of first holes 45 are provided on the pressing plate 43, and a plurality of second holes 46 corresponding to the first holes 45 are provided on the rubber pad 44. The first holes 45 and the second holes 46 are used to pass the fixing rod 16. In other words, the pressing plate 43 and the rubber pad 44 can be connected to the fixing rod 16 through the first holes 45 and the second holes 46. That is, when the fixing plate 15 is arranged between the mounting frame 42 and the pressing plate 43, the fixing rod 16 can pass through the first holes 45 of the pressing plate 43 and the second holes 46 of the rubber pad 44, so that when the electric push rod 41 pushes the pressing plate 43 to move downward, the pressing plate 43 can drive the rubber pad 44 to move downward along the fixing rod 16, thereby achieving clamping and fixing of the electrical equipment. By arranging a fixing component 4 on the carrier 14, when transporting the power equipment, the electric push rod 41 in the fixing component 4 can push the pressing plate 43 and the rubber pad 44 in the fixing component 4 to move, thereby squeezing and fixing the power equipment, avoiding the displacement of the power equipment during transportation, and thus improving the stability of the power equipment during transportation.
