Abstract
Description
A monorail track protection device Technical Field
[0001] This utility model relates to the field of mining support technology, and in particular to a monorail crane track protection device. Background Technology
[0002] Underground electromechanical transportation in coal mines is a crucial aspect of mine production, and monorail systems are currently widely used for auxiliary transportation in roadways. Monorail tracks are typically installed at the top of the roadway, extending directly to the working face. However, due to the complex underground environment, rocks or debris may fall from the roadway top during long-term operation. These foreign objects can become stuck in the tracks, causing the monorail to jam, malfunction, or even lead to safety accidents, thus impacting production efficiency.
[0003] Currently, underground track protection relies heavily on manual periodic inspections and cleaning, which suffers from problems such as delayed response, large blind spots, and a lack of proactive protection mechanisms. Summary of the Invention
[0004] The purpose of this utility model is to provide a monorail track protection device, which achieves active protection and ensures the safe operation of the monorail system by adding a protective cover to the monorail track.
[0005] To achieve the above objectives, this utility model provides a monorail track protection device, including a track clamp for installing the monorail track and a protective cover disposed above the track clamp; the track clamp includes an upper pressure plate, lower support plates disposed on both sides of the bottom of the upper pressure plate and symmetrically arranged, and a suspension rod fixed above the upper pressure plate and extending upward to be fixed to the hanging anchor rod; the upper pressure plate and the lower support plates are fixedly connected by bolts; the monorail track has an I-shaped structure, with its upper wing plate tightly attached to the upper pressure plate, and its two sides clamped on the upper pressure plate by corresponding lower support plates; multiple suspension rods are evenly arranged along the extension direction of the monorail track; the protective cover is disposed above the track clamp and covers the area above the monorail track; it is provided with through holes; the through holes pass through the suspension rods and are installed on the suspension rods.
[0006] With the above structure, the combination of the upper pressure plate and the double-sided lower support plate achieves precise clamping of the I-shaped rail through high-strength bolts, ensuring the levelness and stability of the rail; the protective cover completely covers the top of the rail, blocking falling rocks and debris from entering, thereby achieving active protection, reducing the risk of rail jamming, and ensuring the safe operation of the monorail system.
[0007] Preferably, the protective cover is slidably mounted on the boom with upper and lower limits; a limit block is provided on the boom above the protective cover, allowing the protective cover to slide vertically on the boom; a compression spring is clamped between the protective cover and the upper pressure plate, pressing the protective cover against the limit block. With this structure, the built-in compression spring and the limit block form an adaptive buffer mechanism, cushioning the impact of falling coal gangue on the protective cover and reducing its stress.
[0008] Preferably, the protective cover has an inverted V-shaped structure. With this structure, the top curvature is optimized through fluid dynamics simulation, which can effectively disperse the impact energy of falling rocks.
[0009] Preferably, reinforcing rods are symmetrically arranged on both sides of the bottom of the protective cover; the reinforcing rods are parallel to the extension direction of the protective cover. Through this structural arrangement, the reinforcing rods are welded to the protective cover to form an integral structure, thereby improving the bending stiffness and meeting the installation requirements of large-span tunnels.
[0010] Preferably, material receiving grooves are provided on both sides of the bottom edge of the protective cover. This structure prevents coal gangue or dust from sliding off the protective cover, causing dust pollution or injuring workers at the bottom.
[0011] Preferably, the receiving trough is a canvas bag; one side of it is installed close to the bottom of the protective cover; the other side is installed on a crossbar; the crossbar is a long bar structure that is parallel to the extension direction of the protective cover and symmetrically arranged on both sides of the protective cover; it is fixed to the top of the tunnel by auxiliary anchor bolts.

[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] The orientations mentioned in this specification are based on the orientation of the monorail track protection device of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.
[0024] As shown in Figures 1-4, a monorail track protection device includes a track clamp 2 for mounting the monorail track 1 and a protective cover 3 disposed above the track clamp 2.
[0025] The track clamp 2 includes an upper pressure plate 21, lower support plates 22 arranged symmetrically on both sides of the bottom of the upper pressure plate 21, and a suspension rod 23 fixed above the upper pressure plate 21 and extending upward to be fixed to the hanging anchor rod.
[0026] The upper pressure plate 21 and the lower support plate 22 are fixedly connected by bolts; the monorail track 1 has an I-shaped structure, with its upper flange tightly attached to the upper pressure plate 21, and its two sides clamped onto the upper pressure plate 21 by corresponding lower support plates 22. The combination of the upper pressure plate 21 and the two lower support plates 22, along with high-strength bolts, achieves precise clamping of the I-shaped track, ensuring its levelness and stability.
[0027] The top of the boom 23 is fixed with an anchor bolt shackle, while the suspended anchor bolt is installed on the top of the roadway with an anchoring depth of ≥1.5m. The exposed end is fixed with an anchor bolt lifting ring, and the anchor bolt shackle is installed on the anchor bolt lifting ring.
[0028] Multiple booms 23 are evenly arranged along the extension direction of the monorail track 1; in this embodiment, three booms 23 are provided for each monorail track 1. In practical applications, the number can be reasonably set according to the length of the monorail track 1 and the mass of the roadway top. Because there are three booms 23, there are also three corresponding hanging anchors.
[0029] The protective cover 3 is installed above the track clamp 2 and covers the area above the monorail track 1; it has through holes 31; the through holes 31 pass through the suspension rod 23 and are installed on the suspension rod 23. The protective cover 3 is made of wear-resistant and impact-resistant material to improve impact resistance and durability. The protective cover 3 has an inverted V-shaped structure; the top curvature has been optimized by fluid dynamics simulation to effectively disperse the impact energy of falling rocks. The inverted V-shaped protective cover 3 completely covers the top of the track, blocking falling rocks and debris from entering and reducing the risk of track jamming.
[0030] Specifically, the protective cover 3 can be fixedly installed on the boom 23 or movably installed on the boom 23. In this embodiment, the protective cover 3 is slidably installed on the boom 23. The specific installation method is as follows: a limiting block 231 is provided on the boom 23 above the protective cover 3; the through hole 31 of the protective cover 3 passes through the boom 23 and can slide up and down along the boom 23; a compression spring 32 is held between the protective cover 3 and the upper pressure plate 21, and the compression spring 32 presses the protective cover 3 against the limiting block 231. The built-in compression spring 32 and the limiting block 231 constitute an adaptive buffer mechanism, which buffers the impact of falling coal gangue on the protective cover 3, reducing the impact on the protective cover 3; the structure of the compression spring 32 can absorb the impact force of falling rocks, preventing the protective cover 3 from rigidly colliding with the track. Furthermore, a dustproof sleeve is fitted around the compression spring 32 to prevent coal dust from entering and affecting the buffering performance.
[0031] Preferably, reinforcing rods 33 are symmetrically arranged on both sides of the bottom of the protective cover 3; the reinforcing rods 33 are parallel to the extension direction of the protective cover 3. The reinforcing rods 33 are welded to the protective cover 3 to form an integral structure, thereby improving the bending stiffness and meeting the installation requirements of large-span tunnels.
[0032] Furthermore, to prevent coal gangue or dust from sliding off the protective cover 3 and causing dust storms or injuring workers at the bottom, material receiving troughs 34 are provided on both sides of the bottom edge of the protective cover 3. In this embodiment, the material receiving troughs 34 are canvas bags used to collect fallen rocks or debris, and also provide a certain degree of shock absorption.
[0033] Specifically, the canvas bag is installed on one side of the protective cover 3, close to the bottom of the protective cover 3; the other side is installed on the crossbar 35. The crossbar 35 is a long rod structure that is parallel to the extension direction of the protective cover 3 and symmetrically arranged on both sides of the protective cover 3. The crossbar 35 is fixed to the top of the tunnel by auxiliary anchor bolts. The specific installation method is as follows: the auxiliary anchor bolt is installed on the top of the tunnel, and a lifting ring is fixed to its exposed end. A lifting hook 351 is suspended at the bottom of the lifting ring. The lifting hook 351 includes a rod body, an auxiliary shackle fixed to one end of the rod body, and a hook set at the other end of the rod body. The lifting ring and the auxiliary shackle are detachably connected, and the crossbar 35 is hooked on the hook. One crossbar 35 is fixed to the top of the tunnel by multiple auxiliary anchor bolts. The auxiliary anchor bolts and the hanging anchor bolts are staggered to avoid force conflict.
[0034] To facilitate the cleaning of debris from inside the canvas bag, the bag is detachably mounted on the protective cover 3 and the crossbar 35 via a hanging loop 341 and a hook 36 structure. The detachable canvas bag design makes cleaning easy, and the hook 36 and hanging loop 341 structure allow for quick assembly and disassembly.
[0035] The specific detachable installation method is as follows: hanging rings 341 are evenly installed on both sides of the canvas bag along the extension direction; the hanging rings 341 are installed on the canvas bag by sewing. Hooks 36 are fixed on the bottom of the crossbar 35 and the protective cover 3 corresponding to the hanging rings 341; in this embodiment, the hooks 36 are welded to the corresponding crossbar 35 or protective cover 3, and the hanging rings 341 are hooked on the hooks 36.
[0036] Working principle: When there are falling rocks on the top of the tunnel, the protective cover 3 is pressed down by the impact, and the compression spring 32 buffers the impact force to avoid damage to the track; the falling rocks slide down the slope of the protective cover 3 into the canvas bag, which can be disassembled and cleaned periodically.
[0037] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
