Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining car technology, specifically to a mining car anti-derailment guidance device. Background Technology
[0002] Mining cars are the core equipment for underground and surface transportation in mines. They are mainly responsible for the transfer of materials such as ore, coal, and waste. Their operational stability directly affects the mine's production efficiency and operational safety.
[0003] Currently, underground mines are affected by geological factors such as mining pressure, rock strata movement, and fault slippage. This makes the track foundation prone to uneven settlement or lateral displacement, resulting in problems such as widening of the track gauge, overall track offset to one side, and lateral misalignment at track joints. Lateral track displacement directly disrupts the normal fit between the wheels and the track. When a mine car travels to a lateral section, the contact force between the wheel flange and the track side increases sharply. If the lateral displacement exceeds the effective constraint range of the wheel flange, the wheel is prone to slipping off the track surface. This can lead to transportation interruptions, material spillage, and potentially equipment collisions, injuries, and other safety accidents, severely restricting the continuity and safety of mine production. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model discloses a mine car anti-derailment guidance device. The technical solution adopted includes two tracks and a car. A frame is fixedly installed at the bottom of the car. Wheels are rotatably installed on the sides of both ends of the frame. The four wheels are located on the two tracks respectively. An installation plate is fixedly installed at the bottom of the frame. Two anti-derailment guidance mechanisms are installed on the sides of both ends of the installation plate. The anti-detachment guiding mechanism includes a support wheel, a bearing seat, a guide wheel, a support column, a moving rod, a spring, and a sleeve. The sleeve is fixedly installed in a through hole on one side of the mounting plate. A moving rod is slidably installed inside the sleeve. One end of the moving rod is fixedly connected to the side of the support column. A spring is sleeved on the outside of the moving rod. The two ends of the spring are fixedly connected to the side of the support column and the side of the mounting plate, respectively. The spring is in a compressed state. A bearing seat is fixedly installed on the side of the support column. A support wheel is rotatably installed on the bearing seat. The side of the support wheel contacts the top of the track. A guide wheel is rotatably installed in a groove on the lower side of the support column. The side of the guide wheel contacts the side of the track.
[0005] As a preferred embodiment of this utility model, the support wheel and guide wheel are made of rolled steel.
[0006] As a preferred embodiment of this utility model, the sleeve is made of stainless steel.
[0007] As a preferred embodiment of this utility model, the side of the upper end of the support column is fixedly connected to one end of the guide rod, and the other end of the guide rod passes through a sliding hole on the side of the mounting plate.
[0008] As a preferred embodiment of this utility model, a steel ball is rotatably installed in the spherical groove on the inner wall of the sleeve. Several steel balls are arranged and evenly distributed along the inner wall of the sleeve. The side of the steel ball contacts the side of the moving rod.
[0009] The beneficial effects of this utility model are: 1. This utility model utilizes a spring that can drive a moving rod to slide along a sleeve through its own elastic deformation. When the track gauge widens, the spring releases its elastic potential energy, pushing the support column towards the track side to ensure that the guide wheel is always in close contact with the track side. When the track gauge narrows, the squeezing force of the track on the guide wheel compresses the spring, causing the support column to move away from the track side, so that the support wheel can remain on the track continuously, providing support for the frame and car body. This prevents the wheels from separating from the track due to changes in track gauge, thus preventing the mine car from derailing and avoiding safety accidents.
[0010] 2. The support and guide wheels are made of rolled steel, which has high hardness and wear resistance. It can withstand frequent contact friction during track lateral movement adjustment and the pressure under heavy loads, preventing frequent replacement due to rapid wear. The sleeve is made of stainless steel, possessing excellent rust resistance. It can resist acidic water vapor and dust corrosion in the humid underground environment, preventing rust on the inner wall of the sleeve from obstructing the sliding of the moving rod and ensuring the long-term stable operation of the anti-detachment guide mechanism.
[0011] 3. The guide rod provides guidance for the support column, preventing it from tilting when moving along the track gauge and improving stability. The steel balls on the inner wall of the sleeve convert the sliding friction between the moving rod and the sleeve into rolling friction, significantly reducing frictional resistance during adjustment.

[0014] Example 1 like Figures 1 to 4 As shown, this utility model discloses a mine car anti-derailment guidance device. The technical solution adopted includes two tracks 1 and a car 2. A frame 3 is fixedly installed at the bottom of the car 2. Wheels 4 are rotatably installed on the sides of both ends of the frame 3. The four wheels 4 are located on the two tracks 1 respectively. An mounting plate 5 is fixedly installed at the bottom of the frame 3. Two anti-derailment guidance mechanisms 6 are installed on the sides of both ends of the mounting plate 5. The anti-detachment guiding mechanism 6 includes a support wheel 61, a bearing seat 62, a guide wheel 63, a support column 64, a moving rod 65, a spring 66, and a sleeve 67. The sleeve 67 is fixedly installed in a through hole on one side of the mounting plate 5. The moving rod 65 is slidably installed inside the sleeve 67. The sleeve 67 is made of stainless steel, which has excellent rust resistance and can resist the corrosion of acidic water vapor and dust in the humid environment downhole. This prevents the moving rod 65 from being obstructed due to rust on the inner wall of the sleeve, ensuring the long-term stable operation of the anti-detachment guiding mechanism 6. Several steel balls 8 are rotatably installed in the spherical groove on the inner wall of the sleeve 67. Several steel balls 8 are evenly distributed along the inner wall of the sleeve 67. The sides of the steel balls 8 contact the sides of the moving rod 65. The steel balls 8 on the inner wall of the sleeve 67 convert the sliding friction between the moving rod 65 and the sleeve 67 into rolling friction, greatly reducing the frictional resistance during the adjustment process. One end of the moving rod 65 is fixedly connected to the side of the support column 64. A spring 66 is sleeved on the outer side of the moving rod 65. The two ends of the spring 66 are fixedly connected to the side of the support column 64 and the side of the mounting plate 5, respectively. The spring 66 is in a compressed state. A bearing seat 62 is fixedly installed on the side of the support column 64. A support wheel 61 is rotatably mounted on the bearing seat 62. The side of the support wheel 61... The support column 64 has a groove on its lower side that contacts the top of the track 1. A guide wheel 63 is rotatably mounted in the groove on the lower side of the support column 64. The upper side of the support column 64 is fixedly connected to one end of the guide rod 7. The other end of the guide rod 7 passes through a sliding hole on the side of the mounting plate 5. The guide rod 7 can guide the support column 64 to prevent it from tilting when moving along the track gauge, thus improving stability. The side of the guide wheel 63 contacts the side of the track 1. The support wheel 61 and the guide wheel 63 are made of rolled steel. Rolled steel has high hardness and strong wear resistance, and can withstand the frequent contact friction during the lateral adjustment of the track 1, as well as the pressure under heavy load conditions. To prevent the wheels from wearing out too quickly and requiring frequent replacement, the spring 66 drives the moving rod 65 to slide along the sleeve 67 through its own elastic deformation. When the track gauge widens, the spring 66 releases its elastic potential energy, pushing the support column 64 to move towards the side of track 1, ensuring that the guide wheel 63 is always in close contact with the side of track. When the track gauge narrows, the squeezing force of track 1 on the guide wheel 63 compresses the spring 66, causing the support column 64 to move away from track 1, so that the support wheel 61 can be kept on track 1 continuously, providing support for the frame 3 and the car 2. This prevents the mine car from derailing due to the separation of the wheels 4 from track 1 caused by changes in track gauge, thus avoiding safety accidents.
[0015] The working principle of this utility model is as follows: When the track gauge of track 1 widens due to geological factors, the pre-compression spring 66 releases its elastic potential energy, pushing the support column 64 to move towards the track 1 side, causing the moving rod 65 to slide along the sleeve 67, so that the guide wheel 63 always keeps in contact with the side of track 1, and the support wheel 61 also continuously contacts the top of track 1 to provide support for the frame 3 and the car 2. When the track gauge narrows, track 1 exerts a squeezing force on the guide wheel 63, pushing the support column 64 to move away from track 1 and compressing the spring 66, and the moving rod 65 slides in the opposite direction, while the support wheel 61 and the guide wheel 63 still maintain contact. The contact between the track 1 and the support wheel 61 maintains normal fit between the support wheel 61 and the track 1. At the same time, the support wheel 61 and the guide wheel 63 are made of high-hardness, wear-resistant rolled steel to cope with friction and heavy load. The sleeve 67 is made of stainless steel to resist underground corrosion. The guide rod 7 at the upper end of the support column 64 passes through the sliding hole of the mounting plate 5 to prevent the support column 64 from tilting. The steel balls 8 evenly distributed on the inner wall of the sleeve 67 convert the sliding friction between the moving rod 65 and the sleeve 67 into rolling friction to reduce adjustment resistance. Finally, through the synergistic effect of these structures, the mine car is prevented from derailing, ensuring the continuity and safety of mine transportation.
