[0003] However, the related technologies have at least one of the following problems: the installation of electrical equipment in the related technologies usually relies on manual handling and positioning throughout the entire process; during operation, multiple people are required to manually move the heavy electrical equipment to the vicinity of the target installation location, and then still rely on human coordination to lift it. The entire handling and lifting process is entirely dependent on human labor, especially for large and heavy equipment, which requires multiple people to work together, which is time-consuming and labor-intensive. Utility Model Content

[0004] The technical problem solved by this utility model is that the installation of power equipment in related technologies usually relies on manual handling and positioning throughout the entire process. During operation, multiple people are required to manually move the heavy power equipment to the vicinity of the target installation location, and then it still needs to be lifted by human coordination. The entire handling and lifting process is entirely dependent on human power. Especially for large and heavy equipment, multiple people are required to work together, which is time-consuming and labor-intensive.

[0005] To address the aforementioned problems, this utility model provides a lifting device for installing power equipment, comprising: an equipment transfer assembly having a mounting position; a lifting assembly having a mounting position and being rotatably connected to the mounting position; the lifting assembly having a placement position for supporting the power equipment; and a driving member having a mounting position, one end of which is rotatably connected to the mounting position and the other end of which is rotatably connected to the lifting assembly; wherein, when the driving member is in a retracted state, the lifting assembly forms a first height with the ground; during the process of the driving member changing from a retracted state to an extended state, the lifting assembly rotates around the equipment transfer assembly in a first direction to move the lifting assembly away from the ground; when the driving member is in an extended state, the lifting assembly forms a second height with the ground; the second height is greater than the first height.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: Compared with related technologies, this utility model installs the lifting component for lifting power equipment onto the equipment transfer component. The power equipment can be moved to the target installation position through the equipment transfer component. Then, the lifting component is driven to rotate around the equipment transfer component by the telescopic movement of the drive component, which automatically completes the lifting of the power equipment from the first height at a low position to the second height at a high position. The entire process does not require manual handling or lifting.

[0007] In one embodiment of this utility model, the mounting position is provided with a first connecting seat; the lifting assembly includes: a bearing part; a connecting part, one end of which is rotatably connected to the first connecting seat and the other side is rotatably connected to the bearing part; wherein, the driving member is drively connected to the connecting part.

[0008] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the cooperation between the first link and the connecting part clarifies the rotation fulcrum between the lifting component and the installation position, ensuring that the lifting component can rotate around the fixed fulcrum, improving the stability of the lifting process and preventing equipment shaking; and the direct transmission between the drive component and the connecting part avoids the dispersion of driving force and ensures that the extension force of the drive component can be converted into the rotational force of the lifting component.

[0009] In one embodiment of this utility model, the supporting part includes: a supporting plate; a stop member, the stop member is disposed on the supporting plate, and the stop member is provided with a first rotating shaft and a second rotating shaft that cooperate with the connecting part; the first rotating shaft and the second rotating shaft are arranged along the length direction of the stop member.

[0010] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: the bearing plate provides a bearing surface for the power equipment and is adapted to the shape of the power equipment; the stop member forms a double rotation fulcrum with the connecting part through the first and second rotating shafts, which avoids the bearing part from tilting or deforming due to single-point force; in addition, the stop member can suspend the movement of the equipment on the bearing plate and prevent the equipment from slipping off during lifting or transportation.

[0011] In one embodiment of this utility model, the first connecting seat includes a first support and a second support arranged along the height direction of the mounting position; the connecting part includes: a first connecting rod, one end of which is rotatably connected to the first support and the other end of which is rotatably connected to the first rotating shaft; and a second connecting rod, one end of which is rotatably connected to the second support and the other end of which is rotatably connected to the second rotating shaft.

[0012] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the first link connects the first support and the first rotating shaft, and the second link connects the second support and the second rotating shaft, finally forming a parallelogram linkage mechanism. This ensures that the load-bearing part always maintains a parallel posture during the lifting process, avoids equipment tilting, and effectively prevents the power equipment from sliding due to the shift of the center of gravity. Furthermore, the double-link structure distributes the weight of the equipment to two supports, avoiding excessive force on a single point that could lead to structural damage.

[0013] In one embodiment of this utility model, the second connecting rod is provided with a connecting position; the second support is provided with a second connecting seat on the side opposite to the first support; one end of the driving member is rotatably connected to the second support seat, and the other end is rotatably connected to the connecting position.

[0014] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: one end of the driving component is connected to the second connecting seat, and the other end is connected to the rotation fulcrum of the second connecting rod, so that the second connecting rod, the driving component and part of the equipment transfer assembly form a triangular force structure, ensuring that when the driving component extends or retracts, the driving force can directly drive the second connecting rod to rotate, and then synchronously drive the first connecting rod to achieve the coordinated action of the two connecting rods.

[0015] In one embodiment of this utility model, the end of the first connecting rod that is rotatably connected to the first rotating shaft is defined as the first end; the end of the second connecting rod that is rotatably connected to the second rotating shaft is defined as the second end; the equipment transfer assembly includes a first plane and a second plane, the first plane and the second plane being perpendicular to each other; when the driving member is in a retracted state, the first end, the second end and the stop member are located on the first plane; when the driving member is in an extended state, the first end, the second end and the stop member are located on the second plane.

[0016] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: when the driving component is in the retracted state, the first link, the second link, and the stop are all located on the first plane, forming a compact whole to facilitate movement; when the driving component is in the extended state, the first link, the second link, and the stop are located on the second plane, ensuring structural stability when lifted to the maximum height.

[0017] In one embodiment of this utility model, the equipment transfer assembly includes: a frame, with a mounting position disposed on the frame; a backing plate disposed on the frame and extending in the direction of the mounting position; when the drive component is in a retracted state, the bearing plate abuts against the backing plate.

[0018] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: when the driving component is in the extended state, the abutment plate abuts against the bearing plate, forming a double support with the first and second connecting rods, thus dispersing the pressure of the power equipment weight on the bearing plate.

[0019] In one embodiment of this utility model, the equipment transfer assembly further includes a guide, which is disposed at the mounting position and rotatably connected to the frame.

[0020] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the guide is rotatably connected to the frame; when the power equipment needs to be transferred to the load-bearing plate, the guide comes into contact with the ground to form a guide surface for guiding the power equipment; when the power equipment is already on the load-bearing plate, the guide detaches from the ground to realize the transfer of the power equipment.

[0021] In one embodiment of this utility model, the frame is also provided with rotating wheels.

[0022] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: the rotating wheels allow the equipment transfer components to move flexibly, and construction personnel only need to push to move the power equipment to the target location.

[0023] In one embodiment of this utility model, a jack is provided on the side of the frame closest to the ground.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the addition of jacks increases the contact area between the lifting device and the ground, thereby improving the stability of the entire lifting device when the drive component is extending.

[0025] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) This utility model installs the lifting component for lifting the power equipment onto the equipment transfer component. The power equipment can be moved to the target installation position through the equipment transfer component. Then, the lifting component is driven to rotate around the equipment transfer component by the telescopic movement of the drive component, which automatically completes the lifting of the power equipment from the first height at a low position to the second height at a high position. No manual handling or lifting is required throughout the process. (2) The first link connects the first support and the first shaft, and the second link connects the second support and the second shaft, finally forming a parallelogram linkage mechanism. This ensures that the load-bearing part always maintains a parallel posture during the lifting process, avoids equipment tilting, and effectively prevents the power equipment from sliding due to the shift of the center of gravity. In addition, the double link structure distributes the weight of the equipment to two supports, avoiding excessive force on a single point that could cause structural damage. (3) When the drive component is in the retracted state, the first link, the second link and the stop are all located on the first plane, forming a compact whole to facilitate movement; when the drive component is in the extended state, the first link, the second link and the stop are located on the second plane, ensuring structural stability when lifted to the maximum height.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] See Figure 1 , Figure 1 A structural schematic diagram of a lifting device for installing power equipment provided in an embodiment of this utility model; combined with Figures 2 to 7 Specifically, a lifting device 100 for installing power equipment includes: an equipment transfer assembly 10, a lifting assembly 20, and a driving component 30; the equipment transfer assembly 10 has an installation position; the lifting assembly 20 is located at the installation position and is rotatably connected to the installation position; the lifting assembly 20 has a placement position 21 for supporting the power equipment; the driving component 30 is located at the installation position, with one end rotatably connected to the installation position and the other end rotatably connected to the lifting assembly 20; wherein, when the driving component 30 is in a retracted state, the lifting assembly 20 forms a first height with the ground; when the driving component 30 changes from a retracted state to an extended state, the lifting assembly 20 rotates around the equipment transfer assembly 10 in a first direction to move the lifting assembly 20 away from the ground; when the driving component 30 is in an extended state, the lifting assembly 20 forms a second height with the ground; the second height is greater than the first height.

[0032] Preferably, the drive component 30 is either a hydraulic cylinder telescopic rod or an electric telescopic rod.

[0033] In accordance with specific working conditions, the equipment transfer assembly 10 forms the basis of the lifting device 100.

When the drive component 30 is in a retracted state, the lifting assembly 20 is placed vertically relative to the equipment transfer assembly 10, and the placement position 21 forms a first height with the ground. This state facilitates the movement of the equipment transfer assembly 10 and the placement of the electrical equipment on the lifting assembly 20. As the drive component 30 changes from a retracted state to an extended state, its length increases, pushing the lifting assembly 20 to rotate relative to the mounting position of the equipment transfer assembly 10 in a first direction, thereby moving the lifting assembly 20 away from the ground. When the drive component 30 reaches its fully extended state, a second height is formed between the lifting assembly 20 and the ground. This state facilitates lifting the electrical equipment to a predetermined installation height for operation.

[0034] Furthermore, the mounting position is provided with a first connecting seat 111; the lifting assembly 20 includes a supporting part 22 and a connecting part 23; one end of the connecting part 23 is rotatably connected to the first connecting seat 111, and the other side is rotatably connected to the supporting part 22; wherein, the driving member 30 is drively connected to the connecting part 23.

[0035] Specifically, the lifting assembly 20 includes a support part 22 for carrying electrical equipment and a connecting part 23 for connecting the support part 22 to the equipment transfer assembly 10; one end of the connecting part 23 is rotatably connected to the first connecting seat 111 by a pin, and the other end is rotatably connected to the support part 22 by a pin; the telescopic end 31 of the driving member 30 is connected to the connecting part 23 for transmission, and drives the support part 22 to move through the connecting part 23.

[0036] Furthermore, the support portion 22 includes: a support plate 221 and a stop member 222; the stop member 222 is disposed on the support plate 221, and the stop member 222 is provided with a first rotating shaft 2221 and a second rotating shaft 2222 that cooperate with the connecting portion 23; the first rotating shaft 2221 and the second rotating shaft 2222 are arranged along the length direction of the stop member 222.

[0037] Specifically, the support part 22 includes a support plate 221 and stop members 222 fixedly installed on both sides of the support plate 221; a first rotating shaft 2221 and a second rotating shaft are provided on the stop member 222, and the first rotating shaft 2221 and the second rotating shaft 2222 are spaced apart along the length direction of the stop member 222; the connecting part 23 realizes the movement of the support plate 221 by cooperating with the first rotating shaft 2221 and the second rotating shaft 2222.

[0039] Specifically, a quadrilateral linkage lifting mechanism is formed by the cooperation of the first link 231, the second link 232, the first support 1111 and the second support 1112 in the mounting position, and the first rotating shaft 2221 and the second rotating shaft 2222 on the stop plate; the first connecting seat 111 specifically includes the first support 1111 and the second support 1112 arranged along the height direction of the mounting position; correspondingly, the connecting part 23 includes the first link 231 and the second link, with one end of the first link 231 connected to the first support 1111. The first support 222 is rotatably connected to the second support 1112 via a pin, and the other end is rotatably connected to the first rotating shaft 2221. Thus, the first support 1111, the first connecting rod 231, the first rotating shaft 2221, the stop 222, the second rotating shaft 2222, the second connecting rod 232, and the second support 1112 together constitute a parallel four-bar linkage mechanism, ensuring that the bearing plate 221 remains horizontal during the lifting process.

[0040] Furthermore, the second link 232 is provided with a connecting position 2322; the second support 1112 is provided with a second connecting seat 112 on the side opposite to the first support 1111; one end of the driving member 30 is rotatably connected to the second support seat, and the other end is rotatably connected to the connecting position 2322.

[0041] Specifically, in order to optimize the installation of the drive component 30, a connection position 2322 is provided on the second link 232; at the same time, a second connecting seat 112 is provided on the side of the second support 1112 away from the first support 1111, the bottom end of the drive component 30 is rotatably connected to the second connecting seat 112, and its top end, namely the telescopic end 31, is rotatably connected to the connection position 2322 on the second link 232.

[0042] Furthermore, the end of the first connecting rod 231 that is rotatably connected to the first rotating shaft 2221 is defined as the first end 2311; the end of the second connecting rod 232 that is rotatably connected to the second rotating shaft 2222 is defined as the second end 2321; the equipment transfer assembly 10 includes a first plane 121 and a second plane 122, the first plane 121 and the second plane 122 are perpendicular to each other; when the driving member is in a retracted state, the first end 2311, the second end 2321 and the stop member 222 are located on the first plane 121; when the driving member is in an extended state, the first end 2311, the second end 2321 and the stop member 222 are located on the second plane 122.

[0043] Specifically, to define the deterministic motion of the four-bar linkage, the end of the first link 231 connected to the first rotating shaft 2221 is defined as the first end 2311, and the end of the second link 232 connected to the second rotating shaft 2222 is defined as the second end 2321. Based on this, a first plane 121 and a second plane 122 are divided on the equipment transfer assembly 10, and the first plane 121 and the second plane 122 are perpendicular to each other. When the drive member 30 is in the retracted state, the first end 2311, the second end 2321 and the stop member 222 are basically located on the first plane 121. It can be understood that the first end 2311, the second end 2321 and the stop member 222 are horizontally collinear, and the lifting assembly 20 is retracted at this time. When the drive member 30 is in the extended state, the first end 2311, the second end 2321 and the stop member 222 are vertically collinear, and the lifting assembly 20 is extended at this time.

[0044] It should be noted that the first plane 121 and the second plane 122 are the spatial coplanar states that occur when the first link 231, the second link 232, the first rotating shaft 2221 and the second rotating shaft 2222 are vertically collinear and horizontally collinear under two motion conditions.

[0045] Furthermore, the equipment transfer assembly 10 includes: a frame 12 and abutment plate 13; the mounting position is located on the frame 12; the abutment plate 13 is located on the frame 12 and extends in the direction of the mounting position; when the drive member 30 is in the retracted state, the bearing plate 221 abuts against the abutment plate 13.

[0046] Specifically, the mounting position and the first connecting seat 111 are both located on the frame 12 of the equipment transfer assembly 10; a stop plate 13 is also fixedly installed on the frame 12, extending towards the mounting position, but the length of the stop plate 13 should avoid the movement path of the support plate 221 to ensure the normal movement of the support plate 221; when the drive member 30 is in the retracted state, the support plate 221 and the side of the stop plate 13 facing away from the ground abut against each other, providing support for the support plate 221 in the extended state of the drive member 30, preventing the electrical equipment in the support plate 221 from swaying vertically after being lifted.

[0047] Furthermore, the equipment transfer assembly 10 also includes a guide 14, which is located in the mounting position and rotatably connected to the frame 12.

[0048] Specifically, the guide 14 is hinged to the frame 12; when loading electrical equipment, it can be lowered from the frame 12 and placed on the ground to form a ramp to facilitate pushing the electrical equipment onto the support plate 221; after the electrical equipment is loaded, the guide 14 rotates relative to the frame 12 and detaches from the ground.

[0049] Furthermore, the frame 12 is also provided with rotating wheels 15 to enable convenient movement of the frame 12.

[0050] Furthermore, in order to ensure the stability of the lifting device 100 during the lifting operation and prevent it from tipping over, a jack 16 is provided on the side of the frame 12 closest to the ground. When the frame 12 is moved to the target position and the power equipment needs to be lifted, that is, before the drive component 30 changes from the retracted state to the extended state, the jack 16 is first turned to support it on the ground, the entire frame 12 is lifted and locked; then the drive component 30 is changed from the retracted state to the extended state.

[0051] Preferably, there are multiple jacks 16, which are arranged at intervals along the edge of the frame 12.

[0052] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
