Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of switch protection devices for mining electrical equipment, and in particular to a self-resetting support device for mining switches. Background Technology
[0002] Because mining workplaces have complex geological conditions and contain harmful media such as gas, dust, and water, the protection and operation requirements for underground electrical equipment are extremely high when extracting materials. A single mistake can cause personal injury or huge economic losses, or even catastrophic consequences. Some current electrical equipment switches do not meet these requirements. Moreover, the underground environment is harsh, with bumps, high temperatures and humidity, or high dust concentrations. Static electricity or sparks can all lead to disastrous consequences.
[0003] To address the aforementioned issues, existing patent (CN206412254U) discloses a protective device for a mine electrical equipment switch, comprising an electrical equipment switch, a sealing lock, and a fuse, as well as a housing. The sealing buckle at the inlet, the cavity, and the inner layer of the housing are made of insulating, fire-resistant, and waterproof material, ensuring the mine electrical equipment switch is in a sealed environment. The use of insulating, fire-resistant, and waterproof material prevents static electricity, water ingress, or high-temperature and humidity, thus avoiding sparks. Due to the harsh underground environment and frequent impacts, a high-strength aluminum alloy frame is used to increase strength. Both the switch mounting bracket and the fuse mounting bracket are made of insulating and fire-resistant material to prevent the electrical equipment switch from contacting the protective device housing. LED lights and temperature sensors accurately monitor the operating status of the electrical equipment switch and provide an alarm function. Switch sensors prevent operators from opening the housing while the equipment is in operation or for unauthorized personnel to open it.
[0004] However, in the aforementioned existing technologies, the support equipment relies on its own installation and manufacturing strength to resist falling ores, materials, etc. When the falling object is small in mass, the support can still play a role. However, when the falling object is fast or large in mass, the impact is greater, which will damage the support equipment and affect the normal use of the switchgear. Utility Model Content
[0005] The purpose of this utility model is to provide a self-resetting mine switch support device, which aims to solve the technical problem that the support equipment in the existing technology relies on its own installation and manufacturing strength to resist falling ore, materials, etc. When the falling object is small, the support can still play a role, but when the falling object is fast or large, the impact is large, which causes damage to the support equipment and affects the normal use of the switch equipment.
[0006] To achieve the above objectives, this utility model employs a self-resetting mine switch support device, comprising a mounting plate, a support frame, a first hook spring, an adjusting frame, an inclined plate, a protective plate, a second hook spring, and a base. The support frame is fixedly connected to the mounting plate and located outside the mounting plate. The first hook spring is movably connected to the support frame and located outside the support frame. The adjusting frame is movably connected to the other end of the first hook spring and located below the first hook spring. The inclined plate is fixedly connected to the mounting plate and located above the first hook spring. The protective plate is fixedly connected to the adjusting frame and located outside the adjusting frame, and the protective plate has a groove. The second hook spring is movably connected to the adjusting frame and located below the protective plate. The base is movably connected to the other end of the second hook spring and located outside the second hook spring, and the base has a second hook hole adapted to the second hook spring.
[0007] The support frame includes a support plate and a reinforcing plate. The support plate is fixedly connected to the mounting plate and is located outside the mounting plate. The support plate has a hook hole adapted to the hook spring. The reinforcing plate is fixedly connected to the support plate and is located above the support plate.
[0008] The adjusting frame includes a fixed base and a fixed shaft. The fixed base is fixedly connected to the mounting plate and is located below the support plate. The fixed shaft is fixedly connected to the fixed base and is located inside the fixed base.
[0009] The adjustment frame further includes an adjustment plate, a hanging bridge, and an L-shaped plate. The adjustment plate is rotatably connected to the fixed shaft and is located below the first hook spring. The adjustment plate has an inclined surface. The hanging bridge is movably connected to the other end of the first hook spring and is located above the adjustment plate. The L-shaped plate is fixedly connected to the protective plate and is located below the adjustment plate.
[0010] The protective plate also includes an insertion plate, an extension plate, and a buffer pad. The insertion plate is detachably connected to the protective plate and is located within the groove. The extension plate is fixedly connected to the insertion plate and is located outside the insertion plate. The buffer pad is fixedly connected to the extension plate and is located above the extension plate.
[0011] This utility model discloses a self-resetting mine switch support device. In practical use, the mounting plate is bolted to the top of the switch equipment. When a falling object impacts the protective plate, the protective plate drives the adjusting frame to rotate, causing the first hook spring to stretch. At the same time, the adjusting frame compresses the second hook spring. Relying on the properties of the springs, after dissipating the impact force, the first hook spring pulls the adjusting frame to reset. The second hook spring assists the adjusting frame in resetting and prevents the adjusting frame from shaking due to the reset of the first hook spring. This allows the entire support function to be restored as quickly as possible. This method can effectively solve the problem that the support equipment is easily damaged by falling ore and materials due to its own installation and manufacturing strength.

Detailed Implementation
[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0019] Please see Figures 1 to 4 This utility model provides a self-resetting mine switch support device, including a mounting plate 1, a support frame 2, a hook spring 3, an adjusting frame 4, an inclined plate 5, a protective plate 6, a hook spring 7, and a base 8. The support frame 2 is fixedly connected to the mounting plate 1 and is located outside the mounting plate 1. The hook spring 3 is movably connected to the support frame 2 and is located outside the support frame 2. The adjusting frame 4 is movably connected to the other end of the hook spring 3 and is located below the hook spring 3. The inclined plate 5 is fixedly connected to the mounting plate 1 and is located above the hook spring 3. The protective plate 6 is fixedly connected to the adjusting frame 4 and is located outside the adjusting frame 4, and the protective plate 6 has a groove 604. The hook spring 7 is movably connected to the adjusting frame 4 and is located below the protective plate 6. The base 8 is movably connected to the other end of the hook spring 7 and is located outside the hook spring 7, and the base 8 has a hook hole 801 adapted to the hook spring 7.
[0020] In this embodiment, the mounting plate 1 is bolted to the top of the switchgear. When a falling object impacts the protective plate 6, the inclined plate 5 protects the hook spring 3 from the impact. The protective plate 6 drives the adjusting frame 4 to rotate, causing the hook spring 3 to stretch. At the same time, the adjusting frame 4 compresses the hook spring 7. Relying on the properties of the spring, after dissipating the impact force, the hook spring 3 pulls the adjusting frame 4 to reset. The hook spring 7 assists the adjusting frame 4 in resetting and prevents the adjusting frame 4 from shaking due to the reset of the hook spring 3. This allows the entire support function to be restored as quickly as possible. This method can effectively solve the problem that the support equipment is easily damaged by falling ore and materials due to its own installation and manufacturing strength.
[0021] Furthermore, the support frame 2 includes a support plate 201 and a reinforcing plate 202. The support plate 201 is fixedly connected to the mounting plate 1 and is located outside the mounting plate 1. The support plate 201 has a hook hole 203 adapted to the hook spring 3. The reinforcing plate 202 is fixedly connected to the support plate 201 and is located above the support plate 201.
[0022] In this embodiment, one end of the hook spring 3 is hooked into the hook hole 203, and the reinforcing plate 202 is used to enhance the load-bearing capacity of the support plate 201.
[0023] Furthermore, the adjustment frame 4 includes a fixed base 401 and a fixed shaft 402. The fixed base 401 is fixedly connected to the mounting plate 1 and is located below the support plate 201. The fixed shaft 402 is fixedly connected to the fixed base 401 and is located inside the fixed base 401.
[0024] In this embodiment, the fixing base 401 is fixed to the outside of the mounting plate 1, and the fixing shaft 402 is fixed inside the fixing base 401.
[0025] Furthermore, the adjustment frame 4 also includes an adjustment plate 403, a hanging bridge 404, and an L-shaped plate 405. The adjustment plate 403 is rotatably connected to the fixed shaft 402 and is located below the hook spring 3. The adjustment plate 403 has an inclined surface. The hanging bridge 404 is movably connected to the other end of the hook spring 3 and is located above the adjustment plate 403. The L-shaped plate 405 is fixedly connected to the protective plate 6 and is located below the adjustment plate 403.
[0026] In this embodiment, the hanging bridge 404 is used to connect to the other end of the hook spring 3. The adjusting plate 403 abuts against the inclined surface provided by the adjusting plate 403, so that the L-shaped plate 405 drives the protective plate 6 to remain horizontal. The lower end of the L-shaped plate 405 is connected to one end of the hook spring 7, and the other end of the hook spring 7 is connected to the base 8 through the hook hole 801.
[0027] Furthermore, the protective plate 6 also has an insertion plate 601, an extension protective plate 602, and a buffer pad 603. The insertion plate 601 is detachably connected to the protective plate 6 and is located within the groove 604. The extension protective plate 602 is fixedly connected to the insertion plate 601 and is located outside the insertion plate 601. The buffer pad 603 is fixedly connected to the extension protective plate 602 and is located above the extension protective plate 602.
[0028] In this embodiment, when the support equipment is used, the extension guard plate 602 can be selected to be installed according to the size of the switch equipment. The insertion plate 601 is inserted into the groove 604 of the protective plate 6, and the insertion plate 601 and the protective plate 6 are connected by bolts, so that the extension guard plate 602 and the protective plate 6 are assembled into one piece. The buffer pad 603 is used to reduce the impact force of falling objects, and the extension guard plate 602 is used to extend the protection of the equipment below.
[0029] The beneficial effects of this utility model are as follows: The mounting plate 1 is bolted to the top of the switchgear. When a falling object impacts the protective plate 6, the inclined plate 5 protects the hook spring 3 from the impact. The protective plate 6 causes the L-shaped plate 405 to tilt downwards. The adjusting plate 403 extends the hook spring 3 via the hanging bridge 404. At the same time, the adjusting plate 403 rotates around the fixed shaft 402. The lower end of the L-shaped plate 405 presses against the hook spring 7. Relying on the properties of the spring, after dissipating the impact force, the hook spring 3 pulls the hook spring 7. The adjusting plate 403 is reset, and the hook spring 2 7 assists the protective plate 6 in resetting by pushing the L-shaped plate 405, preventing the adjusting frame 4 from shaking due to the reset of the hook spring 1 3. This allows the entire support function to be restored as quickly as possible. Since the hook spring 1 3 and the hook spring 2 7 are installed by hooks, it is convenient to quickly replace their spare parts. This can absorb the impact of falling objects, and due to its own spring properties, it can return to its original state after the absorption of force, effectively improving the protection of the switchgear and the service life of the support device.
[0030] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
