Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of ultra-high voltage switch housing transfer equipment, specifically an ultra-high voltage switch housing transfer and placement rack. Background Technology
[0002] As the name suggests, ultra-high voltage switchgear is equipment that connects high-voltage or low-voltage cables. Power supply bureaus and substations generally use ultra-high voltage switchgear, which is then stepped down by transformers to low-voltage switchgear, and then to various power distribution boxes. Inside, it is nothing more than an electrical device that assembles some switches, circuit breakers and other protective devices into one unit.
[0003] When ultra-high voltage switchgear is taken out of the workshop, it needs to be moved. The current method is for workers to place the ultra-high voltage switchgear on a flatbed truck, then tie bandages around the switchgear before moving it.
[0004] This method not only wastes workers' time and energy when moving and binding the switch cabinet, but also poses a risk of the switch cabinet tilting and falling over. Utility Model Content
[0005] This utility model provides an ultra-high voltage switch housing transfer and placement rack to solve the defects in the prior art.
[0006] This utility model is achieved through the following technical solution:
[0007] A transfer and placement rack for ultra-high voltage switch housings includes a movable plate. The four corners of the bottom surface of the movable plate are provided with casters with locking function. The movable plate has two longitudinal slide grooves and one transverse slide groove located on the same longitudinal line. The longitudinal slide groove and the transverse slide groove are respectively provided with a longitudinal slider and a transverse slider that can slide and lock. The top surface of the longitudinal slider and the transverse slider is provided with a movable blind hole. The movable plate is provided with a fixed blind hole located on the same transverse line as the movable blind hole on the transverse slider. Both the transverse blind hole and the fixed blind hole are provided with internal threads and are threadedly connected to limit rods.
[0008] The movable plate of this application is equipped with casters, which can drive the switchgear to move. When the switchgear is placed on the base plate, a limit rod is first rotated into the fixed blind hole. Then, the switchgear is aligned with the limit rod. The horizontal and vertical sliders are moved according to the length and width of the switchgear and locked after being moved. The limit rod is then rotated into the corresponding movable blind hole, thereby limiting the switchgear in four directions (front, back, left, and right). This effectively prevents the ultra-high voltage switchgear from tilting during movement. At the same time, since rotating the limit rod saves time and effort, it saves workers' time and energy.
[0009] Preferably, both the transverse and longitudinal sliders are provided with threaded holes, and screws are threaded into the screw holes. The screws extend out of the moving plate and are rotatably connected to the moving plate via bearings. Rotating the screws causes the corresponding transverse and longitudinal sliders to move.
[0010] Preferably, the transverse and longitudinal sliders are provided with several movable blind holes evenly distributed along their length. The multiple movable blind holes allow for the adaptation to ultra-high voltage switch housings of varying lengths and widths, increasing their applicability.
[0011] Preferably, the base plate also has two limiting slots located on the same longitudinal line. A U-shaped limiting plate slides within each slot, and the limiting plate has a threaded hole with a threaded rod threaded into it. The rod passes through the base plate and is rotatably connected to it via a bearing. The base plate also has two grooves located on the same transverse line as the corresponding limiting slots. The U-shaped limiting plate can hold two wheels on the bottom surface of the ultra-high voltage switch housing, while the grooves ensure that the other two wheels are on the same transverse plane as the restrained wheels, guaranteeing the horizontal placement of the switchgear. The limiting plate, driven by the rod, can move to accommodate ultra-high voltage switch housings of different sizes, further increasing the stability of the switchgear during movement.
[0012] Preferably, one side of the base plate is hinged to a ramp, the top surface of which is an upward sloping surface from left to right, and the uppermost side is on the same horizontal plane as the top surface of the base plate. The ramp ensures that the switch cabinet can be quickly pushed onto the moving plate, while the ramp hinge ensures that the ramp is placed on the moving plate and moves synchronously when the moving plate moves, avoiding the ramp affecting the movement.
[0013] Preferably, the base plate has several placement holes in the horizontal direction, and the limiting rod is inserted into the placement holes, which facilitates the placement of the limiting rod.
[0014] The beneficial effects of this utility model are as follows: The use of this application not only limits the front, back, left, and right sides of the ultra-high voltage switch housing via the limiting rod, preventing the ultra-high voltage switch housing from tilting and falling over when moved, but also saves more physical effort compared to the binding method. Furthermore, this application can be applied to ultra-high voltage switch housings of different sizes, thereby increasing its range of applications. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] A transfer and placement rack for ultra-high voltage switch housings, such as Figure 1 As shown. It includes a movable plate, with four corners of its bottom surface equipped with locking casters. The movable plate has two longitudinal grooves and one transverse groove on the same longitudinal line. The longitudinal and transverse grooves respectively house a sliding and locking longitudinal slider 3 and a transverse slider 2. The top surfaces of the longitudinal slider 3 and transverse slider 2 have movable blind holes 4. The movable plate has a fixed blind hole 5 on the same transverse line as the movable blind hole 4 on the transverse slider 2. Both the transverse blind hole and the fixed blind hole 5 have internal threads and are threadedly connected to a limit rod 6. The transverse slider 2 and longitudinal slider 3 each have threaded holes with internal threads fitted to screws. The movable plate has a circular hole that extends from the outside to the corresponding transverse and longitudinal grooves. The screw passes through the circular hole and is rotatably connected to the circular hole via a bearing.
[0021] This application features casters on the movable plate, enabling the switchgear to move. When placing the switchgear on the base plate 1, a limiting rod 6 is first rotated into the fixed blind hole 5. The switchgear is then aligned with the limiting rod 6. Next, the horizontal slider 2 and vertical slider 3 are moved according to the length and width of the switchgear and locked after movement. Specifically, a screw is rotated; the rotation of the screw moves the corresponding horizontal slider 2 and vertical slider 3, ensuring they remain stationary when not rotating. The limiting rod 6 is then rotated into the corresponding movable blind hole 4, thus limiting the switchgear in four directions (front, back, left, and right). This effectively prevents the ultra-high voltage switchgear from tilting during movement. Furthermore, rotating the limiting rod 6 is time-saving and labor-saving, thus reducing the time and effort required for workers.
[0022] The horizontal slider 2 and the vertical slider 3 are evenly provided with several movable blind holes 4 along their length. The multiple movable blind holes 4 can accommodate ultra-high voltage switch housings of different lengths and widths, increasing the range of applications.
[0023] The base plate 1 also has two limiting slots located on the same longitudinal line. A U-shaped limiting plate 7 slides within each limiting slot. The limiting plate 7 has a threaded hole with a threaded screw threaded into it. The screw passes through the base plate 1 and is rotatably connected to it via a bearing. The base plate 1 also has two grooves 8 located on the same transverse line as the corresponding limiting slots. The U-shaped limiting plate 7 can hold two wheels on the bottom surface of the ultra-high voltage switch housing, while the grooves 8 ensure that the other two wheels are on the same transverse plane as the restrained wheels, guaranteeing the horizontal placement of the switchgear. The limiting plate 7, moved by the screw, can accommodate ultra-high voltage switch housings of different sizes, further increasing the stability of the switchgear during movement.
[0024] One side of the base plate 1 is hinged to a ramp 9. The top surface of the ramp 9 is an upward sloping surface from left to right, and its uppermost side is on the same horizontal plane as the top surface of the base plate 1. The ramp 9 ensures that the switch cabinet can be quickly pushed onto the moving plate, and the hinge of the ramp 9 ensures that the ramp 9 is placed on the moving plate and moves synchronously when the moving plate moves, thus avoiding the ramp 9 affecting the movement.
[0025] The base plate 1 has several placement holes 10 opened laterally, and the limiting rod 6 is inserted into the placement hole 10. The placement hole 10 facilitates the placement of the limiting rod 6.
[0026] The use of this application not only limits the front, back, left, and right sides of the ultra-high voltage switch housing via the limiting rod 6, preventing the ultra-high voltage switch housing from tilting and falling over when moved, but also saves more physical effort for workers compared to the binding method. Furthermore, this application is applicable to ultra-high voltage switch housings of different sizes, thereby increasing its range of applications.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
