Description
Technical Field
[0001] The utility model relates to the field of power grid GIS platform maintenance devices, in particular to a power grid GIS platform maintenance device. Background Art
[0002] The maintenance of the power grid GIS platform is an important part of ensuring the safe and stable operation of equipment. It has the advantages of compact structure, strong resistance to pollution and external interference, and is widely used in power systems such as substations, high-voltage lines, and power plants. With the reform and development of the power industry, the safety and reliability of power grid facilities have been put forward higher requirements, which also requires the improvement of GIS maintenance technology and management level.
[0003] When inspecting and repairing a power grid platform with existing technology, it is often necessary to dismantle it first and then use a lifting device to move it to an area where it is convenient to operate for inspection and maintenance. This lifting device usually has the ability to move, but its movement lacks a good restriction mechanism. Since the power grid platform facilities are heavy, they are likely to move uncontrollably due to the weight of the facilities during the lifting process, which may cause the lifted facilities to fall, and in serious cases, it may cause accidents, resulting in immeasurable losses and casualties. Some devices with restriction capabilities require manual control each time they are restricted, which is time-consuming and labor-intensive, and once the staff forgets the restrictions, there are still safety hazards.
[0004] Therefore, those skilled in the art provide a power grid GIS platform maintenance device to solve the problems raised in the above background technology. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings of the existing technology and to propose a power grid GIS platform maintenance device. The device is stable during the hoisting process and is not prone to shaking. The entire device can only be moved after it is hoisted to the top. The rope hoisting has a buffer structure, which can reduce the impact of sudden falls or other factors, and has high safety.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a power grid GIS platform maintenance device, comprising two supporting mechanisms, the two supporting mechanisms comprising two brackets, both of which are provided with a limiting rod slidingly therethrough, both of which are provided with a sliding groove on the inner side, a sliding rod being provided for sliding engagement between the two brackets, a return spring being provided at the front and rear positions between the upper ends of the two limiting rods and the interior of the brackets, a load-bearing mechanism being provided at the upper end of the supporting mechanism, the load-bearing mechanism comprising a top plate, a pressure plate being provided slidingly therethrough inside the top plate, and a plurality of dampers being provided between the lower end of the pressure plate and the interior of the top plate;
[0007] A lifting mechanism is provided at one side of the upper end of the load-bearing mechanism, and the lifting mechanism includes a crane. A rope is provided at the output end of the crane. A moving mechanism is provided at the lower end of each of the two supporting mechanisms. The two moving mechanisms include two rotating bodies. Rollers are provided for rotation between the front and rear sides of the two rotating bodies, and a gear column is fixed around the rod body part inside the two rollers.
[0008] Furthermore, the two limiting rods are both fixedly sleeved with square rings near their upper ends, and the parts of the sliding rods located inside the bracket on both sides are both located below the square rings.
[0009] Furthermore, a clamping block is fixedly provided at the lower end of each of the two limiting rods, and the size of the grooves provided inside the two clamping blocks is consistent with the size of the teeth around the gear column.
[0010] Furthermore, a hook is provided at the lower end of the rope, and the sliding rod is fixedly provided at the upper part of the hook at the lower end of the rope.
[0011] Furthermore, the middle part of the pressure plate is a cylinder, and the two side parts thereof are rectangular parallelepipeds, and the rope is wound around the middle cylindrical part of the pressure plate.
[0012] Furthermore, the two rotating bodies are both rotatably arranged at the lower end of the bracket, and the two limiting rods are both rotatably arranged at the center of the upper end of the rotating body.
[0013] Furthermore, the dimensions of the lower portions of the two limiting rods are consistent with the dimensions of the lower portion of the interior of the bracket, and the dimensions of the upper rectangular portions of the two limiting rods are consistent with the dimensions of the upper portion of the interior of the bracket.
[0014] Furthermore, push handles are fixedly provided at the lower outer sides of the two support mechanisms, and protective shells are fixedly provided at the lower ends of the two support mechanisms.
[0015] The utility model has the following beneficial effects:
[0016] 1. The utility model proposes a power grid GIS platform maintenance device, which is hoisted by a crane and a hook of a rope. Since the hook of the rope is fixedly connected to the sliding rod, under the restriction of the slide, the hoisting process is a linear motion, and the rising process is relatively stable and not prone to shaking. Once the hoisted power grid equipment suddenly drops, it is subjected to the tension of the rope. With the cooperation of the pressure plate and the damper, the impact force can be buffered, thereby reducing damage and further improving the stability and safety of the maintenance hoisting.
[0017] 2. The utility model proposes a power grid GIS platform maintenance device. Only when the sliding rod rises to the maximum height will the limiting rod move up to the maximum height. At this time, the restriction on the gear column on the roller will be released. Through the above design, the entire equipment can be moved and the transfer work can be completed only after the lifting is completed. When the rope is still performing the lifting work below, the limiting rod will restrict the gear column, and the transfer cannot be performed at this time. It is more stable and controllable. This type of restriction method does not require manual control, is simple to operate, and saves manpower and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Reference Figure 1The utility model provides an embodiment: a power grid GIS platform maintenance device, comprising two supporting mechanisms 1, a load-bearing mechanism 2 is provided on the upper end of the supporting mechanism 1, a lifting mechanism 3 is provided at one side of the upper end of the load-bearing mechanism 2, a push handle 4 is fixedly provided at the lower outer side of the two supporting mechanisms 1, a protective shell 5 is fixedly provided at the lower end of the two supporting mechanisms 1, and a moving mechanism 6 is provided at the lower end of the two supporting mechanisms 1.
[0028] Specifically, the handle 4 is pushed to move the entire device, and the hoisting mechanism 3 can cooperate with the moving mechanism 6. The moving mechanism 6 can only move after the hoisting is completed to prevent it from moving around during the hoisting process.
[0029] Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , the two supporting mechanisms 1 include two brackets 101, both brackets 101 are provided with a limiting rod 104 that slides through them, both brackets 101 are provided with a sliding groove 102 on the inside, a sliding rod 103 is provided between the two brackets 101, and a return spring 105 is provided between the upper ends of the two limiting rods 104 and the front and rear parts of the brackets 101. The two moving mechanisms 6 include two rotating bodies 603, and rollers 601 are provided between the front and rear sides of the two rotating bodies 603. The rod parts inside the two rollers 601 are fixedly sleeved with gear columns 602.
[0030] The two limiting rods 104 are fixedly sleeved with a square ring near the upper end, and the parts of the sliding rod 103 on both sides of the bracket 101 are located below the square ring. The lower ends of the two limiting rods 104 are fixedly provided with a clamping block, and the size of the grooves opened in the two clamping blocks is consistent with the size of the teeth on the gear column 602. The two rotating bodies 603 are rotatably set at the lower end of the bracket 101. The two limiting rods 104 are rotatably set at the center of the upper end of the rotating body 603. The size of the lower part of the two limiting rods 104 is consistent with the size of the lower part of the bracket 101. The size of the upper rectangular part of the two limiting rods 104 is consistent with the size of the upper part of the bracket 101.
[0031] Specifically, when the sliding rod 103 moves to the top, the two limiting rods 104 are also at the maximum height. When the sliding rod 103 moves downward, the two limiting rods 104 are reset by the reset spring 105, and can move downward and wrap the gear column 602 through the protrusion at the bottom, so that it cannot rotate.
[0032] Reference Figure 2 、 Figure 3 and Figure 4The load-bearing mechanism 2 includes a top plate 201, a pressure plate 202 is slidingly provided inside the top plate 201, a plurality of dampers 203 are provided between the lower end of the pressure plate 202 and the inside of the top plate 201, a hoisting mechanism 3 is provided at one side of the upper end of the load-bearing mechanism 2, and the hoisting mechanism 3 includes a crane 301, a rope 302 is provided at the output end of the crane 301, a hook is provided at the lower end of the rope 302, and a sliding rod 103 is fixedly provided at the upper part of the hook at the lower end of the rope 302. The middle part of the pressure plate 202 is a cylinder, and the two side parts thereof are rectangular parallelepipeds. The rope 302 is wound around the middle cylindrical part of the pressure plate 202;
[0033] Specifically, when the rope 302 suddenly lifts a heavy object, the multiple dampers 203 can play a buffering role, making the lifting operation more stable. Since the lower end of the rope 302 is fixedly connected to the sliding rod 103, when the rope 302 is lowered, the sliding rod 103 will also drop.
[0034] Working principle: Before the device is hoisted, the sliding rod 103 is at the maximum height, and the two limiting rods 104 are also at the maximum height. The gear column 602 will not be restricted, and the entire equipment can move freely through the roller 601. After moving to the maintenance position, the crane 301 can be started. At this time, the rope 302 and its hook will carry the sliding rod 103 and move downward steadily along the slide 102. At this time, the two limiting rods 104 lose their restriction and move downward under the influence of the return spring 105, wrapping the gear column 602. At this time, the gear column 602 cannot move, so the roller 601 cannot rotate. During the hoisting, the entire device will not move. After the rope 302 and its hook lift the power grid equipment to the highest point, it can be moved to other areas for maintenance. If it is affected by bumps during the transfer, since the rope 302 is also wrapped around the pressure plate 202, it will cause the pressure plate 202 to press down multiple dampers 203, which can cushion the impact force and make the transfer and hoisting process more stable.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
