Description

Technical Field

[0001] This utility model relates to the field of rock mass clearing in mine roadways, and in particular to a device for clearing unstable rock mass in mine roadways. Background Technology

[0002] Due to geological tectonic movements and mining stress, roadway walls often exhibit phenomena such as crack development and rock loosening, forming safety hazards such as hanging rock blocks and unstable rock masses. During the construction and maintenance of mine roadways, the clearing of unstable rock masses (such as fractured rock layers, loose gravel, weathered rock layers, etc.) is a core link to ensure operational safety. How to safely and effectively remove loose or hanging rock blocks has become a major challenge.

[0003] Existing technologies mainly rely on equipment such as hydraulic breakers to directly impact or break rock masses to remove unstable rocks. However, the high-frequency vibration caused by the equipment's reliance on impact force or high pressure to break the rock mass can easily induce secondary loosening of the surrounding rock mass. This vibration increases the loosening rate of roadway support structures such as anchor bolts, requiring additional support costs and reducing the safety of mine production. Moreover, operators need to operate the equipment at close range, facing risks such as rock collapse and flying debris. The equipment also has poor stability in complex roadway terrain and is prone to overturning due to ground tilting or vibration. Therefore, a mine roadway unstable rock mass clearing device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device for cleaning unstable rock masses in mine roadways, which aims to improve the problem in the prior art that "vibration can easily induce secondary loosening of the surrounding rock mass, leading to an increase in the loosening rate of the roadway support structure".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for cleaning unstable rock masses in mine roadways, comprising a base, a support column fixedly connected to the top of the base, a friction mechanism provided on the top of the base, the friction mechanism comprising a round rod and a long rod, the round rod being slidably connected to the inner wall of the support column, a connecting rod hinged to the right side surface of the round rod, the middle part of the long rod being hinged to the middle part of the connecting rod, a disc fixedly connected to the right side of the long rod, a friction block fixedly connected to the right side of the disc, and an auxiliary mechanism provided on the left side of the disc.

[0012] As a further description of the above technical solution:

[0013] The support frame is L-shaped, and the inner wall of the support frame is slidably connected to the outer wall of the round rod.

[0014] As a further description of the above technical solution:

[0015] The sleeve is fitted onto the outer wall of the round rod, and the central axis of the sleeve coincides with the central axis of the round rod.

[0016] As a further description of the above technical solution:

[0019] The auxiliary mechanism also includes an electric cylinder, which is fixedly connected to the left side of the support column, and the right side of the output shaft of the electric cylinder is fixedly connected to the left side of the round rod.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by setting up a friction mechanism, the electric cylinder works to make the friction block reciprocate on the rock wall.

The operator can adjust the position of the tracked vehicle in real time through wireless remote control, reducing the risk and labor intensity of manual cleaning and improving cleaning efficiency and safety.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a mine roadway unstable rock mass clearing device, including a base 1. A tracked vehicle 15 is fixedly connected to the bottom of the base 1. The tracked vehicle 15 is of model 350-1200t, providing the device with mobility to adapt to uneven terrain in the roadway. The height is adjusted by a hydraulic system to ensure the stability of the device. The tracked vehicle 15 has a built-in wireless transmission module for wireless remote control. A bucket 16 is fixedly connected to the right side of the tracked vehicle 15. The bucket 16 is welded from high-strength wear-resistant steel and is used to load the cleared rock fragments, enabling simultaneous clearing and transportation in conjunction with the tracked vehicle 15. A support column 2 is fixedly connected to the top of the base 1. The base 1 and the support column 2 form the foundation of the overall structure, supporting the friction mechanism 11 and the auxiliary mechanism 10. The friction mechanism 11 is provided on the top of the base 1.

[0031] Reference Figures 2-4The friction mechanism 11 includes a round rod 111 and a long rod 113. The round rod 111 is slidably connected to the inner wall of the support column 2. A connecting rod 112 is hinged to the right side surface of the round rod 111. The middle part of the long rod 113 is hinged to the middle part of the connecting rod 112. A disc 114 is fixedly connected to the right side of the long rod 113. A friction block 115 is fixedly connected to the right side of the disc 114. The friction block 115 is made of tungsten carbide alloy, and staggered grooves are formed on the surface of the friction block 115 to increase the friction with the rock. The friction force of the body causes the output shaft of the electric cylinder 104 to directly drive the round rod 111 to slide along the inner wall of the support column 2. The sliding of the round rod 111 drives the connecting rod 112 to swing through the hinge point. The motion is further transmitted to the disc 114 through the lever effect of the long rod 113, driving the friction block 115 to approach or move away from the rock surface, applying periodic friction force to the rock, enhancing the gripping force on the loose rock, and gradually peeling off the unstable rock layer. An auxiliary mechanism 10 is provided on the left side of the disc 114.

[0032] Reference Figures 1-3 The auxiliary mechanism 10 includes a support frame 101, which is fixedly connected to the right side of the support column 2. A sleeve 102 is fixedly connected to the right side of the support frame 101, and a circular plate 103 is fixedly connected to the right side of the sleeve 102. The support frame 101 is L-shaped, and the inner wall of the support frame 101 is slidably connected to the outer wall of the circular rod 111 to ensure the guiding stability of the circular rod 111 when it slides.

[0033] Reference Figures 2-4 The sleeve 102 is fitted onto the outer wall of the round rod 111. The central axis of the sleeve 102 coincides with the central axis of the round rod 111. The right side of the round plate 103 is hinged to the left side of the connecting rod 112. The round rod 111 passes through and is slidably connected to the inner wall of the round plate 103. When the round rod 111 slides, the round plate 103 moves synchronously with the round rod 111 to maintain the swing trajectory of the connecting rod 112 and avoid the mechanism from jamming due to uneven force on the friction block 115.

[0034] Reference Figures 2-4 The auxiliary mechanism 10 also includes an electric cylinder 104, which is fixedly connected to the left side of the support column 2. The right side of the output shaft of the electric cylinder 104 is fixedly connected to the left side of the round rod 111, and the left side of the round rod 111 is rigidly connected to the output shaft of the electric cylinder 104, transmitting thrust and limiting the radial displacement of the round rod 111.

[0035] Working principle: In use, the device is moved along the mine roadway to the area to be cleaned by the tracked vehicle 15. Then, the electric cylinder 104 is started, which drives the round rod 111 to slide to the right, so that the friction block 115 contacts the rock surface. The electric cylinder 104 continuously outputs power, and the output shaft of the electric cylinder 104 pushes the round rod 111 to slide back and forth on the inner wall of the support column 2. The movement of the round rod 111 is transmitted to the long rod 113 through the connecting rod 112. The long rod 113 drives the disc 114 and the friction block 115 to move left and right. The friction block 115 contacts the unstable rock mass, so that the friction block 115 makes reciprocating friction motion on the rock wall. The high hardness grooves of the tungsten carbide alloy of the friction block 115 break the protruding parts and unstable structures on the surface of the rock mass.

[0036] When different locations need to be cleared, the operator uses a wireless remote control to move the tracked vehicle 15. The bucket 16 moves synchronously under the drive of the tracked vehicle 15, collecting the stripped gravel into the bucket 16. This prevents the gravel and rock in the mine roadway from blocking the tracked vehicle 15's progress. The operator can adjust the position of the tracked vehicle 15 in real time via wireless remote control, reducing the risk of personnel being exposed to dangerous areas. Through the coordinated action of the friction mechanism 11 driven by the electric cylinder 104 and the auxiliary guidance system, the stripping and clearing of unstable rock in the mine roadway is achieved, reducing the risks and labor intensity of manual clearing and improving clearing efficiency and safety.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
