Description

Technical Field

[0001] The utility model relates to the technical field of mining vehicle connection, in particular to a new type of universal hard connection device for mining vehicles. Background Technique

[0002] Special vehicles for mine track transportation. To adapt to the narrow conditions of underground roadways, the external dimensions are compact. There are freight cars, personnel cars, material cars, etc. Mine cars are narrow-gauge railway handling vehicles for transporting bulk materials such as coal, ore, and waste rock in mines, and generally need to be towed by locomotives or winches. Mine cars are divided into 5 categories according to different structures and unloading methods: fixed mine cars (material cars, flat cars), tipping mine cars, single-side curved rail side-dumping mine cars, bottom (side)-dumping mine cars, and shuttle mine cars. Vehicles towed by locomotives or winches to transport coal, gangue, equipment, and personnel. Mine cars are mainly used for track transportation in underground roadways, mine shafts, and on the ground of mines, and are the most widely used transportation equipment in coal mines.

[0003] The existing connection device for narrow-gauge mining vehicles is used for the connection and support between narrow-gauge mining vehicles. However, the existing connection device is not convenient to automatically adjust the running angle according to the undulation of the slope during use, which is likely to cause problems such as difficult turning of vehicle operation and derailment of vehicles on slopes. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the existing connection device is not convenient to automatically adjust the running angle according to the undulation of the slope during use in the existing technology, which is likely to cause problems such as difficult turning of vehicle operation and derailment of vehicles on slopes, and a new type of universal hard connection device for mining vehicles is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a new type of universal hard connection device for mining vehicles, including a towing rod, rotating sleeves are installed at both ends of the towing rod, a connection head is installed at one end of the rotating sleeve, and reinforcing ribs are symmetrically installed on the outer side of the towing rod.

[0006] Preferably, lifting rings are installed at both ends of the top of the towing rod, and an installation hole is opened in the middle of the connection head.

[0007] Preferably, the hole distance between the two installation holes is 2000 mm.

[0008] Preferably, the aperture of the installation hole is 72 mm.

[0009] Preferably, the shaft diameter of the connection head is 40 mm.

[0010] Compared with the existing technology, the advantages and positive effects of the utility model are as follows.

[0011] In the present utility model, the connection between adjacent vehicles is facilitated by the connector. The connector relies on the rotating sleeve to achieve 360-degree rotation. When the material transportation vehicle travels on the track, especially at the curve where the curvature radius of the track changes, the rotating sleeve can automatically adjust the angle of the connector according to the trend of the curve, so that the connection between the front and rear vehicles always remains smooth, without excessive pulling or twisting due to the bending of the track. It is convenient to automatically adjust the running angle according to the curvature radius of the track and the undulation of the slope, ensuring the stability of the connection, preventing uneven stress on the connection part caused by the slope change. The traction rod plays a supporting role, which is beneficial to bearing the tensile and compressive forces generated during the vehicle's driving. At the same time, during vehicle pushing and braking, it plays a buffering role, effectively solving the intense collision generated during vehicle pushing and braking during material transportation, avoiding problems such as difficult turning during vehicle operation and derailment of the vehicle at the slope parting, and preventing excessive instantaneous stress on the connection part caused by sudden braking.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0020] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification. Embodiment

[0021] As Figures 1-6 shown, the present utility model provides a technical solution: a new type of universal rigid connection device for mining vehicles, including a towing bar 4. Rotating sleeves 3 are installed at both ends of the towing bar 4. A connection head 2 is installed at one end of the rotating sleeve 3. Reinforcing ribs 5 are symmetrically installed on the outer side of the towing bar 4. Lifting rings 1 are installed at both ends of the top of the towing bar 4. An installation hole is provided in the middle of the connection head 2. The hole pitch of the two installation holes is 2000 mm, the aperture of the installation hole is 72 mm, and the shaft diameter of the connection head 2 is 40 mm.

[0022] In this embodiment, as Figures 1-6 shown, this device is used for the connection and support between narrow-gauge vehicles in mines. The connection head 2 facilitates the connection of adjacent vehicles. The connection head 2 can achieve 360-degree rotation by relying on the rotating sleeve 3. When the material transport vehicle is traveling on the track, especially at the bend where the radius of curvature of the track changes, the rotating sleeve 3 can automatically adjust the angle of the connection head 2 according to the direction of the bend, so that the connection between the front and rear vehicles always remains smooth, and there will be no excessive pulling or twisting due to the bending of the track. It is convenient to automatically adjust the running angle according to the radius of curvature of the track and the undulation of the slope, ensuring the stability of the connection, preventing uneven stress on the connection part caused by the slope change. The towing bar 4 plays a supporting role, which is beneficial to bearing the tensile force and pressure generated during the vehicle's driving process. At the same time, during the vehicle's pushing and braking, it plays a buffering role, effectively solving the intense collision generated during the vehicle's pushing and braking in material transportation, avoiding problems such as difficult turning of the vehicle during operation and derailment of the vehicle on the slope when changing lanes, and preventing excessive instantaneous stress on the connection part caused by sudden braking. The reinforcing ribs 5 are beneficial to strengthening the strength of the towing bar 4, improving the stability and reliability of the towing bar 4 during use.

[0023] Working principle of this embodiment: During use, first connect adjacent vehicles through the connector 2. During the use of the track, the connector 2 relies on the rotating sleeve 3 to achieve 360-degree rotation. When the material transportation vehicle travels on the track, especially at the bend where the radius of curvature of the track changes, the rotating sleeve 3 can automatically adjust the angle of the connector 2 according to the trend of the bend, so that the connection between the front and rear vehicles always remains smooth. The towing bar 4 plays a supporting role, which is beneficial to bearing the tensile and compressive forces generated during the vehicle's travel. At the same time, when the vehicle is pushing and braking, it plays a buffering role, effectively solving the intense collision generated during the vehicle's pushing and braking during material transportation. The reinforcing rib 5 is beneficial to enhancing the strength of the towing bar 4, improving the stability and reliability of the towing bar 4 during use.

[0024] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
