[0023] Preferably, the second height adjustment assembly 10 includes a second height adjustment box 21, which is provided with a threaded hole 22 and two positioning holes 23. The threaded hole 22 is threadedly connected to the threaded rod 17, and the two positioning rods 18 are respectively slidably connected to the two positioning holes 23. A second height adjustment groove 24 is provided on the side wall of the second height adjustment box 21 away from the first height adjustment box 13. A positioning rod 25 arranged in a vertical direction is fixedly connected in the second height adjustment groove 24. The connecting block assembly 11 is slidably connected to the positioning rod 25.

[0024] The working principle and beneficial effects of the above technical solution are: During use, the first joint 1 and the second joint 2 are respectively installed on different carriages. By connecting the first joint 1 and the second joint 2, the connection of adjacent carriages of a mining locomotive can be achieved. Before connecting the first joint 1 and the second joint 2, the motor 16 is first used to drive the threaded rod 17 to rotate, thereby adjusting the height of the second height adjustment box 21 to an appropriate height. Then, by moving one of the carriages, a collision occurs between the first joint 1 and the second joint 2, and the connection block assembly 11 enters between the upper pressure plate 6 and the joint body 4. Then, by lowering the upper pressure plate 6, the upper pressure plate 6 and the joint body 4 clamp the connection block assembly 11. Finally, the locking pin 8 is inserted into the connection hole 1 7 and the connection hole 2 12 to complete the locking of the connection state of the first joint 1 and the second joint 2, thereby achieving the function of connecting and traction of adjacent carriages.
[0025] By setting the first height adjustment component 9, the first joint 1 and the second joint 2 with a large height difference can be matched; by setting the second height adjustment component 10, the first joint 1 and the second joint 2 can be accurately matched; by setting the upper pressure plate 6 that can be moved up and down, the distance between the upper pressure plate 6 and the joint body 4 is enlarged, which facilitates the entry of the connecting block component 11, reduces the difficulty of matching the first joint 1 and the second joint 2, and thereby improves the efficiency of the connection action; by raising and lowering the upper pressure plate 6, the connecting block component 11 can be clamped by the upper pressure plate 6 and the joint body 4, thereby facilitating the locking component to complete the locking, improving the stability of the connection, and further improving the efficiency of the connection action; by setting the isolation cloth 1 20 and the isolation cloth 2 28, the first height adjustment slot 14 and the second height adjustment slot 24 are separated from the external environment, preventing dust, debris, etc. in the environment from entering the first height adjustment slot 14 and the second height adjustment slot 24 and causing damage to the mechanical structure, thereby extending the service life of the traction connector.
[0026] Example 2: Based on Example 1, the connecting block assembly 11 includes a first connecting block 29 and a second connecting block 30. The first connecting block 29 is slidably connected to the positioning rod 25 in the up and down directions. The first connecting block 29 is fixedly connected to a center rod 31 in the front and back directions. The second connecting block 30 is rotatably connected to the center rod 31. The upper and lower side walls of the second connecting block 30 away from the first connecting block 29 are both provided with an inclined surface 32. The connecting hole 2 12 is provided on the second connecting block 30. A rotation control assembly is provided inside the second connecting block 30. The rotation control assembly is used to control the relative rotation of the second connecting block 30 and the center rod 31.

[0028] Preferably, two mounting cavities 41 corresponding to the second control slot 36 are provided in the second connecting block 30, and two locking slots 1 42 are provided in the second connecting block 30. The two locking slots 1 42 are respectively located on the upper and lower sides of the center rod 1 31. A locking block 1 43 is slidably connected in each locking slot 1 42 along the up and down directions. Each locking slot 1 42 is respectively connected to a mounting cavity 41. The locking control assembly includes a control plate 1 44. The control plate 1 44 is fixedly connected to the side wall of the control block 1 38 away from the second connecting hole 12. The control plate 1 44 is slidably connected in the horizontal direction to the control slot 2 36. A slope four 45 is provided on the side wall of the control plate 1 44 away from the control block 1 38 and away from the center rod 1 31. A control block 2 46 is connected to the mounting cavity 41 in a sliding manner along the up and down directions. The control block 2 46 includes a disk 47. A mounting plate 1 48 is fixedly connected to the circular surface of the disk 47. A spring three 49 is fixedly connected between the mounting plate 1 48 and the top surface of the mounting cavity 41. The disk 47 contacts the side wall of the control plate 1 44 away from the center rod 1 31. A connecting plate 1 50 is fixedly connected to the end of the mounting plate 1 48 close to the center rod 1 31. The other end of the connecting plate 1 50 is fixedly connected to the locking block 1 43.
[0029] The working principle and beneficial effects of the above technical solution are: In the initial state, a portion of the control block 38 is in the connecting hole 2 12. When the locking pin 8 is inserted into the connecting hole 2 12, the inclined surface 2 33 contacts the inclined surface 39, thereby squeezing the control block 38 to slide toward the mounting groove 1 35, thereby driving the control plate 1 44 to move toward the control groove 2 36, so that the disc 47 changes from contact with the inclined surface 45 to contact with the surface of the control plate 1 44 away from the center rod 1 31, so that the control block 2 46 moves away from the center rod 1 31, and then drives the locking block 1 43 to be withdrawn from the control groove 37 through the connecting plate 1 50, so that the second connecting block 30 can rotate relative to the first connecting block 29.
[0030] When the locking pin 8 is pulled out from the second connecting hole 12, the control block 38 returns to its initial position under the action of the second spring 40. At the same time, the control block 46 moves toward the center rod 31 under the action of the third spring 49, so that the locking block 43 is reinserted into the locking groove 42, so that the second connecting block 30 remains in a horizontal state and cannot rotate relative to the first connecting block 29, thereby facilitating the connection between the first connecting block 29 and the second connecting block 30 and avoiding the second connecting block 30 not being in a horizontal state and failing to engage with the first joint 1 smoothly.
[0031] When the locking pin 8 is inserted into the second connecting hole 12, the relative rotation function of the first connecting block 29 and the second connecting block 30 is unlocked, which facilitates the carriage to pass through slopes, deep pits and other sections; when the locking pin 8 is pulled out from the second connecting hole 12, the rotation function of the first connecting block 29 and the second connecting block 30 can be automatically locked, thereby facilitating the connection action of the first connecting block 29 and the second connecting block 30.

The lower surface of the mounting plate 2 80 is fixedly connected to an extrusion plate 96 through several groups of springs 95.
[0036] The working principle and beneficial effects of the above technical solution are: When the connecting block assembly 11 enters between the connector body 4 and the upper pressure plate 6, the trigger block 1 57 is squeezed and slides in the direction of entering the trigger cavity 1 55. During the sliding process of the trigger block 1 57, the spring 4 58 is set to buffer the impact of the trigger block 1 57, thereby reducing the impact force of the connecting block assembly 11 on the connector body 4, thereby improving the service life of the connector body 4; as the trigger block 1 57 is squeezed into the trigger cavity 1 55, under the action of the inclined surface 5 60, the trigger rod 62 is squeezed in the direction away from the center rod 2 51, so that the locking block 2 54 is withdrawn from the control groove 4 53, thereby realizing the connection between the connector body 4 and the installation body 4. The relative rotation function between the mounting frame 3 is unlocked; when the second connecting block 30 is separated from the trigger block 1 57, the trigger block 1 57 is automatically reset under the action of the spring 4 58. At the same time, after the squeezing effect of the trigger block 2 59 is lost, the trigger rod 62 moves toward the direction close to the center rod 2 51 under the action of the spring 5 63, so that the locking block 2 54 is reinserted into the control groove 4 53, thereby realizing the relative rotation locking between the joint body 4 and the mounting frame 3. The entire process does not require manual control by the staff, which reduces the work intensity of the staff and improves the efficiency of the connection and separation process of the first joint 1 and the second joint 2.
[0037] As the trigger block 57 is squeezed into the trigger chamber 55, the lower end of the control rod 66 changes from contact with the second horizontal section 573 to contact with the inclined section 572, and finally changes to contact with the first horizontal section 571, thereby realizing the downward movement of the upper pressure plate 6 under the action of gravity; when the upper pressure plate 6 drops to the low position, under the action of spring six 71 (the spring six 71 is in a compressed state when the locking plate one 69 is inserted into the locking groove three 64), the locking plate one 69 is pulled out from the locking groove three 64 and enters the inclined groove 73, so that the locking effect between the locking pin 8 and the upper pressure plate 6 disappears, and the locking pin 8 falls under the action of gravity and passes through the connecting hole one 7 and the connecting hole two 12, completing the connection between the first joint 1 and the second joint 2.
[0038] By setting the locking plate 69, the locking pin 8 and the upper pressure plate 6 are locked, which prevents the locking pin 8 from falling when the first joint 1 and the second joint 2 are not connected, thereby causing the locking pin 8 to be damaged by impact. Furthermore, by setting the inclined slot 73, when the upper pressure plate 6 falls to the specified position, the locking pin 8 is automatically released, thereby realizing the automatic connection action, further reducing the operation content of the staff, reducing the work intensity of the staff, and improving the execution efficiency of the connection action.
[0039] As the locking pin 8 falls, the mounting plate 2 80 is driven to fall, causing the extrusion plate 96 to squeeze the control rod 2 91, causing the control rod 2 91 to move downward. Through the cooperation of the inclined surface 86 and the inclined surface 92, the locking plate 2 85 is squeezed out of the locking hole 2 83 and inserted into the locking groove 4 89, thereby achieving the locking of the relative displacement of the locking pin 8 and the upper pressure plate 6 again, avoiding the locking pin 8 from falling out due to the bumps during the use of the traction connector, and improving the stability of the connection.
[0040] When the first joint 1 and the second joint 2 need to be separated, the motor 2 76 drives the threaded rod 2 77 to rotate, thereby driving the reset block 79 to move upward, first squeezing the spring 95 to make the squeezing plate 96 move upward, and under the action of the spring 8 94, the control rod 2 91 moves upward, and then under the action of the spring 6 71, the locking plate 2 85 leaves the locking groove 4 89, so that the locking pin 8 can move relative to the upper pressure plate 6, and then, under the pushing action of the reset block 79, it is driven by the mounting plate 2 80 to move upward and leave the connecting hole 1. 7 and connecting hole two 12 until it returns to its initial position; when the first joint 1 and the second joint 2 are separated, the trigger block one 57 returns to its initial position under the action of the spring four 58, and then the upper pressure plate 6 is pushed upward by the trigger block one 57 to return it to its initial position, and under the interaction of the inclined groove 73 and the inclined surface seven 72, the locking plate one 69 is reinserted into the locking groove three 64 to lock the locking pin 8, and then the reset block 79 is returned to the mounting groove two 75 by the operation of the motor two 76, so as to prevent the reset block 79 from affecting the falling of the mounting plate two 80.
