Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment maintenance technology, and in particular to a coal mine electromechanical auxiliary fixing structure. Background Technology

[0002] The electrical control boxes or hydraulic stations of underground coal mine equipment, such as coal mining machines and tunneling machines, are usually large and heavy. During routine maintenance or troubleshooting, they need to be moved to a dedicated maintenance platform and securely fixed.

[0003] In existing maintenance operations, maintenance platforms are usually equipped with clamping devices, which clamp and fix the main body of the electromechanical equipment through clamping plates on both sides to prevent it from shaking or shifting during maintenance, thereby ensuring the smooth progress of maintenance work and the safety of operators.

[0004] The structure of coal mine electromechanical equipment is often not a regular cube. Many pieces of equipment may have irregular extended parts or their own center of gravity may be off-center. When the above-mentioned method of clamping only the main body of the equipment is used, those extended, suspended parts are prone to swaying or even sagging under the vibration generated by maintenance work due to the lack of effective support, resulting in the entire equipment being unstable.

[0005] This unstable fixed state not only affects the accuracy of maintenance operations, but also poses a potential threat to the safety of maintenance personnel, making it difficult for existing fixing structures to meet the needs of safe and stable fixing of all types of electromechanical equipment.

[0006] Therefore, this utility model proposes a coal mine electromechanical auxiliary fixing structure to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of instability and safety hazards caused by the lack of effective auxiliary support when fixing irregular or off-center electromechanical equipment in the existing coal mine electromechanical auxiliary fixing structure, this utility model aims to provide a coal mine electromechanical auxiliary fixing structure with improved structure that can effectively solve the above problems.

[0008] This utility model provides a coal mine electromechanical auxiliary fixing structure, including: a base, a platform, a limiting column, ball bearings, and a clamping plate; and an auxiliary support mechanism disposed between the base and the platform.

[0009] The auxiliary support mechanism includes an installation block, an L-shaped folding block, a second fixing block, a lifting column, a limiting block, and a support plate.

[0010] Furthermore, the mounting block is fixedly connected to the bottom of the platform, the second fixing block is fixed to the inner wall of the bottom of the base, the L-shaped folding block is rotatably connected to the second fixing block, and one end of the L-shaped folding block is pressed by the mounting block; the limiting block is fixed to the outer wall of the dust cover; the bottom end of the lifting column is hinged to the other end of the L-shaped folding block, and the lifting column slides through the base and is guided by the limiting block. The top end of the lifting column is fixedly connected to a support plate. Through the linkage of the platform pressing down, auxiliary support for the electromechanical equipment is automatically achieved.

[0011] Preferably, the coal mine electromechanical auxiliary fixing structure further includes a cleaning mechanism, which is installed on the limiting post 1 and is used to actively remove coal slag and dust from the ball bearings and the limiting post 1. The cleaning mechanism consists of a pneumatic cleaning part, a scraping cleaning part, and a sewage discharge part. The pneumatic cleaning part includes an air outlet installed on the outer wall of the limiting post 1, as well as an air supply pipe and a gas distribution box connected to the air outlet. The scraping cleaning part includes a carbon scraper plate installed inside the limiting post 1 and located below the ball bearings, as well as a water spray pipe penetrating the outer wall of the limiting post 1 and having its water outlet facing the carbon scraper plate and the ball bearings, and a water source distribution box. The sewage discharge part includes a sewage discharge port connected to the bottom of the limiting post 1, as well as a transmission pipe and a sewage collection box connected to the sewage discharge port.

[0012] Preferably, in order to provide effective cushioning protection when the electromechanical equipment is lowered, a plurality of buffer bars are provided between the bottom of the platform and the base. The buffer bars can absorb impact energy when the platform is lowered under weight, preventing the equipment and structure from being damaged by hard collision.

[0013] Preferably, in order to precisely limit the final descent position of the platform, a limiting plate is fixedly connected to both sides of the platform. When the platform descends to the predetermined height, the end face of the limiting plate can contact and abut against the inner wall of the base, thereby achieving stable positioning of the platform.

[0014] Preferably, in order to prevent large external particles from entering the movement gap and affecting the normal rotation of the ball bearings, a dust cover is also provided on the base. The dust cover covers the gap between the ball bearings and the platform, forming a physical barrier; and the clamping plate is provided on top of the dust cover.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the ball bearings used in mobile electromechanical equipment are easily jammed in coal mine dust and slag environments, leading to positioning difficulties and mechanism failure. It actively and continuously removes slag and dust from the ball bearings, ensuring that the ball bearings rotate flexibly, so that the electromechanical equipment can move smoothly and be positioned accurately.

[0016] 2. This utility model solves the problem of instability when facing irregularly shaped or offset electromechanical equipment by setting up an auxiliary support mechanism that links the mounting block, L-shaped folding block, lifting column and support plate. The existing technology only clamps the middle of the electromechanical equipment, which leads to instability when facing electromechanical equipment. The support plate is automatically lifted by the weight of the electromechanical equipment itself, providing additional auxiliary support points for the equipment and greatly improving the stability of the fixation.

[0017] 3. This utility model solves the problem that heavy electromechanical equipment may be damaged by impact when it is lowered by setting a buffer bar between the platform and the base. It provides effective buffering during the equipment placement process and protects the equipment and platform from impact damage. Attached Figure Description

[0027] Working principle: When the coal mine electromechanical equipment is placed on top of the platform 5, the platform 5 is lowered under pressure, and the mounting block 301 at the bottom of the platform 5 also falls down. The mounting block 301 presses against one end of the L-shaped folding block 302, and the L-shaped folding block 302 rotates around the fixed block 303 that is rotatably connected. The other end of the L-shaped folding block 302 pushes the bottom end of the lifting column 304. The lifting column 304 slides up under the guidance of the limiting block 305 fixed to the outer wall of the base 1. The support plate 306 at the top of the lifting column 304 rises up accordingly, thereby providing auxiliary support for the part of the electromechanical equipment that extends out. During the descent of the platform 5, the buffer rod 9 at the bottom of the platform 5 is compressed to provide a buffering effect until the limiting plates 10 on both sides of the platform 5 contact the inner wall of the base 1. The platform 5 stops falling and is placed securely. When the electromechanical equipment is lowered and moved, the cleaning mechanism 2 is activated. The gas provided by the gas distribution box 206 is sprayed out through the air supply pipe 205 to the air outlet 204 set on the outer wall of the limiting column 7, blowing away the dust on the surface of the limiting column 7. If there is still coal slag inside the limiting column 7, the scraper plate 202 located below the ball bearing 6 will scrape it off first. At the same time, the water source provided by the water distribution box 207 is sprayed through the water spray pipe 201 onto the scraper plate 202 and the ball bearing 6 to wash away the coal slag. The wastewater after washing flows along the scraper plate 202 into the drain port 203 at the bottom of the limiting column 7, and then is collected in the wastewater collection box 208 through the transmission pipe 209 for unified treatment. The dust cover 8 covers the gap between the ball bearing 6 and the platform 5 to prevent large debris from entering. When the platform 5 is in place, the clamping plate 4 set on the top of the dust cover 8 is activated to clamp and fix the electromechanical equipment.
