Description

Technical Field

[0001] The utility model application relates to the technical field of connection devices, in particular to a hard connection device for narrow-gauge mining vehicles. Background Art

[0002] The hard pull rod device for mining flatbed cars is suitable for connecting various types of mining cars and flatbed cars for transporting coal, gangue, materials, etc. It is also suitable for connecting mining personnel cars. Among them, narrow-gauge electric locomotives are electric locomotives with a track gauge smaller than the standard track gauge. Such locomotives are usually used in specific areas or for specific purposes, such as forest railways, enterprise dedicated lines or local railways.

[0003] The traditional hard connection device for narrow-gauge mining vehicles has a relatively complex connection structure when connected, which is not convenient for adapting to the complex and changeable transportation conditions such as uphill, downhill and turning transportation of flatbed trucks in underground tunnels. It is easy to fall off when going up and downhill and turning. After the narrow-gauge vehicles adopt soft connections, it is easy for the front and rear vehicles to collide with each other when multiple vehicles are transported at the same time, which reduces the firmness and safety of the connection. Summary of the Invention

[0004] In order to solve the problem that the existing hard connection device of narrow-gauge mining vehicles is easy to fall off on uphill and downhill and curved road conditions, and the soft connection is easy to cause mutual collision when multiple vehicles are transported, the utility model provides a hard connection device for narrow-gauge mining vehicles to solve the above problems.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A hard connection device for a narrow-gauge mining vehicle comprises a connector and a connecting rod, wherein both ends of the connecting rod are movably connected with a connecting sleeve, both ends of the connecting rod are threadedly fixed with a ball head, the two connecting sleeves are slidably sleeved on the outside of the ball head, the inside of the connecting sleeves outside the two ball heads are slidably sleeved with a universal ring, and the inside of the connecting sleeves outside the universal ring are both threadedly fixed with a connector.

[0007] Furthermore, the outer surfaces of the two connecting heads, the connecting sleeve and the connecting rod are coated with asphalt paint, and the outer surface of the asphalt paint of the connecting rod is coated with black and yellow warning paint.

[0008] Furthermore, movable holes cooperating with the connecting rod are formed at the opposite ends of the two connecting sleeves, and the diameters of the movable holes are smaller than the outer ring diameter of the ball head.

[0009] Furthermore, the outer side of the connecting sleeve is rotatably connected to a handle via a fixing bolt for lifting the connecting head, and the distance between the connecting sleeve and the inside of the handle is greater than the distance between the fixing bolt and the edge of the connecting sleeve.

[0010] Furthermore, the handle is configured to be U-shaped with the opening facing the connecting sleeve, and both ends of the handle are rotatably sleeved on the fixing bolt, and the fixing bolt is threadedly fixed inside the connecting sleeve.

[0011] Furthermore, both connecting sleeves on the side of the handle are embedded with grease nipples, and the grease nipples are connected to the interior of the connecting sleeve on the outside of the ball head. Sealing rubber is fixed inside the grease nipples for injecting grease to lubricate the ball head.

[0012] Furthermore, the inner sides of the ends of the two universal rings away from the connector are both configured to be arc-shaped to match the outer surface of the ball head, and the outer ring diameter of the universal ring is equal to the outer ring diameter of the ball head.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model solves the problem that the front and rear vehicles collide with each other due to the soft connection of multiple vehicles in transportation, and solves the problem that the conventional hard connection is prone to tilting and pressing when going uphill and downhill and causing accidents when turning, and solves the problem that the hard connection device of the existing narrow-gauge mining vehicle is easy to fall off when going uphill and downhill and in curved road conditions, and the soft connection is easy to collide with each other when multiple vehicles are transported. Combined with the handles at both ends, the connection device is more convenient and labor-saving to install and move. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Reference Figure 1 and Figure 2 A hard connection device for narrow-gauge mining vehicles includes a connector 1 and a connecting rod 6. Both ends of the connecting rod 6 are movably connected with a connecting sleeve 2. Both ends of the connecting rod 6 are threadedly fixed with a ball head 5. The two connecting sleeves 2 are slidably sleeved on the outside of the ball head 5. The inside of the connecting sleeves 2 outside the two ball heads 5 are both slidably sleeved with a universal ring 4, and the inside of the connecting sleeves 2 outside the universal ring 4 are both threadedly fixed with a connector 1.

[0021] Specifically, the outer surfaces of the two connecting heads 1, the connecting sleeve 2 and the connecting rod 6 are coated with asphalt paint, and the outer surface of the asphalt paint of the connecting rod 6 is coated with black and yellow warning paint. The opposite ends of the two connecting sleeves 2 are provided with movable holes that cooperate with the connecting rod 6, and the diameters of the movable holes are smaller than the outer ring diameter of the ball head 5, which is convenient for the connecting sleeve 2 to move on the connecting rod 6. The outer sides of the connecting sleeves 2 are rotatably connected to the handle 3 through the fixing bolt 7, which is used to lift the connecting head 1. The distance between the connecting sleeve 2 and the inside of the handle 3 is greater than the distance between the fixing bolt 7 and the edge of the connecting sleeve 2. The handle 3 is set to face the connecting sleeve 2 with the opening The sleeve 2 is "U"-shaped, and both ends of the handle 3 are rotatably sleeved on the fixing bolts 7, and the fixing bolts 7 are threadedly fixed inside the connecting sleeve 2. The two connecting sleeves 2 on the side of the handle 3 are both embedded with grease nipples 8, and the grease nipples 8 are connected to the inside of the connecting sleeve 2 on the outside of the ball head 5. A sealing rubber is fixed inside the grease nipple 8 for injecting grease to lubricate the ball head 5. The inner sides of the two universal rings 4 at one end away from the connecting head 1 are both set to an arc shape that matches the outer surface of the ball head 5, which facilitates the sliding fit between the universal ring 4 and the ball head 5. The outer ring diameter of the universal ring 4 is equal to the outer ring diameter of the ball head 5, which facilitates the insertion of the universal ring 4 into the interior of the connecting sleeve 2.

[0022] Working principle: When it is necessary to install a hard connection device for a narrow-gauge mining vehicle, first sleeve the two connecting sleeves 2 on the connecting rod 6 in opposite directions, then push the connecting sleeve 2 to expose the end of the connecting rod 6, screw the ball head 5 to the end of the connecting rod 6 and fix it, then push the connecting sleeve 2, sleeve the connecting sleeve 2 on the outside of the connecting rod 6, and then insert the universal ring 4 into the inside of the connecting sleeve 2, and make the side of the universal ring 4 slide and fit with the outer side of the ball head 5, and finally screw the connecting head 1 to the inside of the connecting sleeve 2 and fix it. When it is necessary to move the hard connection device for a narrow-gauge mining vehicle, pull the handle 3 to rotate the handle 3 perpendicular to the connecting sleeve 2, and the hard connection device for the narrow-gauge mining vehicle can be moved by pulling the handle 3. When it is necessary to lubricate the ball head 5, pass the needle with butter through the sealing rubber of the grease nipple 8, and inject the butter into the outer surface of the ball head 5 inside the connecting sleeve 2 through the grease nipple 8 to achieve lubrication of the ball head 5.
