[0037] With the rapid economic development, enterprises are constantly pursuing higher production efficiency, and mining enterprises are no exception. However, in the mining industry, the manually operated car arrester / automatic non-adjustable car arrester used in mine transportation not only has low operation efficiency, but also has a small application range and cannot adapt to the changing on-site conditions.

[0038] To solve the above technical problems, the present application provides an adjustable automatic car arrester in the tank. The car arrester uses a motor to drive the arrester claw to rotate and horizontally move along the lead screw to the working position. At the same time, the induction plate at the bottom of the arrester claw cooperates with two vertically placed in-place sensors fixed on one side of the spacer sleeve to detect the position of the arrester claw and control the stop of the motor. In this way, the working position of the arrester claw can be adjusted according to the body length of the vehicle during operation, and it can adapt to the transportation of various types of mine cars / flatbed trucks.

[0039] Please refer to Figures 1 to 6As shown in the figure, the adjustable automatic vehicle arrester in the tank provided by the present application includes a base 3. Along the long side of the base 3, a motor 10, a reducer 11, a coupling 12, a lead screw 8, a spacer 18, and a buffer device 19 are sequentially arranged. The output shaft of the motor 10 is connected to the reducer 11. The output shaft of the reducer 11 is connected to one end of the lead screw 8 through the coupling 12. The other end of the lead screw 8 is movably connected to the spacer 18. The spacer 18 is connected to the buffer device 19. The mating shaft of the buffer device 19 is connected to the second bearing block 22. A lead screw nut 7 is sleeved outside the lead screw 8. A retaining claw 6 is sleeved outside the lead screw nut 7. A first bearing block 13 is arranged between the lead screw 8 and the coupling 12. A sensing device 16 is arranged on one side of the spacer 17.

[0040] Further, in this embodiment, the adjustable automatic vehicle arrester in the tank further includes a housing 5 covering the upper part of the base 3. An opening for the retaining claw 6 to extend out is provided at the top of the housing 5. A limiting groove for the retaining claw 6 to translate along the lead screw 8 is arranged on the side surface of the housing 5. The extending direction of the limiting groove is parallel to the extending direction of the lead screw 8. The opening is communicated with the limiting groove. The edge of the limiting groove is wrapped with a nylon strip 9 to prevent the retaining claw 6 from wearing the housing 5 during movement.

[0041] Further, in this embodiment, a limiting plate 15 is further arranged on the base 3. The limiting plate 15 is located below the opening of the housing 5.

[0042] Further, in this embodiment, an induction plate 25 fixedly connected to the retaining claw 6 is arranged at the bottom of the retaining claw 6. The retaining claw 6 is connected to the lead screw nut 7. In practical applications, the motor 10 drives the lead screw 8 to rotate through the reducer 11 and the coupling 12. The lead screw nut 7, the retaining claw 6, and the induction plate 25 can be regarded as a whole and rotate along with the lead screw 8 and translate along the lead screw 7 in the direction close to / away from the motor 10.

[0043] Further, in this embodiment, the sensing device 16, the induction plate 25, and the limiting plate 15 are located on one side of the lead screw 8, and the limiting groove is located on the other side of the lead screw 8.

[0044] Further, in this embodiment, the sensing device 16 includes a first in-place sensor 23 and a second in-place sensor 24. The first in-place sensor 23 is located above the second in-place sensor 24. The first in-place sensor 23 is used to detect whether the retaining claw 6 moves in place, and the second in-place sensor 24 is used to detect whether the retaining claw 6 rotates back to the initial position.

[0045] For the convenience of understanding, the direction in which the retaining claw 6 rotates towards the limiting groove side is defined as the first direction, and the direction in which the retaining claw 6 rotates towards the limiting plate 15 side is defined as the second direction.

[0046] In practical applications, in the initial state, the pawl 6 is placed on the limit plate 15, and the induction plate 25 is located at the front end of the signal emission hole of the second in-place sensor 24; in the working state, the motor 10 drives the lead screw 8 to rotate in the first direction. The lead screw 8 simultaneously drives the lead screw nut 7, the pawl 6, and the induction plate 25 to rotate from the initial position in the first direction and move along the lead screw 8 in the direction close to the motor 10. The pawl 6 rotates to the bottom edge of the limit groove and is restricted from further rotation. At this time, the induction plate 25 is located at the front end of the signal emission hole of the first in-place sensor 23, blocking the signal emitted by it. The pawl 6 continues to translate in the limit groove in the direction close to the motor 10. When the first in-place sensor 23 detects that the predetermined distance is reached between it and the induction plate 25, the motor 10 automatically cuts off the power, and the pawl 6 stops moving and is locked, that is, the pawl 6 reaches the working position.

[0047] Further, in this embodiment, chamfers of 0 - 5° are respectively provided on the lead screw nut 7 and the spacer sleeve 18. The chamfer on the lead screw nut 7 is provided between the lead screw nut 7 and the lead screw 8, and the chamfer on the spacer sleeve 18 is provided between the spacer sleeve 18 and the lead screw nut 7; the angle of the chamfer is preferably 3°.

[0048] The purpose of setting the chamfer is to enable the pawl to rotate and return to its original position by self-locking after the vehicle blocking operation is completed. In practical applications, after the vehicle blocking operation is completed, the motor 10 drives the lead screw 8 to rotate in the second direction. The lead screw 8 simultaneously drives the lead screw nut 7, the pawl 6, and the induction plate 25 to rotate from the initial position in the second direction and move along the lead screw 8 in the direction away from the motor 10. However, affected by the self-weight of the pawl 6 and the restriction of the upper edge of the limit groove, the pawl 6 can only first move horizontally to the side of the spacer sleeve 18. After the edge of the lead screw nut 7 is caught inside the spacer sleeve 18, the chamfers on the lead screw nut 7 and the spacer sleeve 18 are self-locked by friction, overcoming the influence of the self-weight of the pawl 6 and causing the pawl 6 to rotate in the second direction back to the initial position, that is, above the limit plate 15. At this time, the induction plate 25 is located at the front end of the signal emission hole of the second in-place sensor 24, blocking the signal of the second in-place sensor 24. When the second in-place sensor 24 detects that the predetermined distance is reached between it and the induction plate 25, the motor 10 automatically cuts off the power.

[0049] Further, in this embodiment, the buffer device 19 further includes a disc spring 20 and a rubber pad 21. In the buffer device 19, multiple disc springs 20 and a single rubber pad 21 are connected in series to reduce the impact force caused when the car pusher pushes the mine car into the cage 26, and avoid deformation and cracking of the pawl 6. For special operating conditions with relatively large impact forces, other buffer devices 19 can be added at appropriate positions on the lower plate of the cage 26 to assist the operation.

[0050] Further, in this embodiment, the bottom of the outer shell 5 is fixedly connected to the base 3 through the fixed angle steel 4 and bolts 2, and the base 3 is fixedly connected to the lower plate of the cage 26 through the fixed plate 1 and bolts 2.

[0051] Further, in this embodiment, both the first bearing block 13 and the second bearing block 22 are provided with copper sleeves inside, and an oil filling port 14 is provided on the upper part of the copper sleeve, which can be used in cooperation with a grease gun for oil injection lubrication to ensure the smoothness of the operation.

[0052] Further, the adjustable automatic car arrester in the tank provided by the present application can be linked with the car pusher to achieve automatic car arrest, or be remotely controlled by remote control.

[0053] The working principle of the present application will be described below:

[0054] Please refer to Figures 5 to 6 As shown, for the convenience of understanding, the moving direction of the mine car / flatbed car is defined as forward, and its opposite direction is defined as backward. The adjustable automatic car arrester 27 provided by the present application can adjust the working position of the arrester claw according to the body length of the operating vehicle. Figure 5 This is a working simulation diagram of the adjustable automatic car arrester 27 provided by the present application for fixing double mine cars 28. Figure 6 This is a working simulation diagram of the adjustable automatic car arrester 27 provided by the present application for fixing a single mine car / flatbed car 29.

[0055] It can be seen that four adjustable automatic car arresters 27 are installed on the lower plate of the cage 26, and two of the adjustable automatic car arresters 27 are located on both sides of the front end of the track, and two of the adjustable automatic car arresters 27 are located on both sides of the rear end of the track.

[0056] First, the two adjustable automatic car arresters 27 at the front end of the track rotate and translate the arrester claws 6 to the working position. The car pusher pushes the mine car or flatbed car into the cage 25, and the vehicle is blocked from moving forward by the two front arrester claws 6. After all the single-operation vehicles have entered, the two adjustable automatic car arresters 27 at the rear end of the track are started, so that their arrester claws 6 rotate and translate behind the rear wheels of the operating vehicle, and the operating vehicle is fixed in the central area of the lower plate of the cage 25 to ensure the smooth transportation of the cage 25.

[0057] Please refer to Figures 1 to 4 As shown, in the initial state, the arrester claw 6 is placed on the limit plate 15, and the induction plate 25 is located in front of the signal emission hole of the second in-place sensor 25.

[0058] When the vehicle-blocking operation starts, the motor 10 is powered on and starts. The output shaft of the motor 10 rotates in the first direction. After the torque is increased by the speed reducer 11, the output shaft of the speed reducer 11 drives the lead screw 8 to rotate in the first direction through the coupling 12. At the same time, the lead screw 8 drives the lead screw nut 7, the blocking claw 6, and the induction plate 25 to rotate in the first direction from the initial position and move along the lead screw 8 in the direction close to the motor 10. The blocking claw 6 rotates to the bottom edge of the limit groove and is restricted from further rotation. At this time, the induction plate 25 is located at the front end of the signal emission hole of the first in-place sensor 23, blocking the signal emitted by it. And the blocking claw 6 continues to translate in the limit groove in the direction close to the motor 10. When the first in-place sensor 23 detects that the distance between it and the induction plate 25 reaches a predetermined distance, the motor 10 automatically cuts off the power, and the blocking claw 6 stops moving and locks, that is, the blocking claw 6 reaches the operation position.

[0059] After the vehicle-blocking operation ends, the motor 10 starts again. The output shaft of the motor 10 rotates in the second direction. After the torque is increased by the speed reducer 11, the output shaft of the speed reducer 11 drives the lead screw 8 to rotate in the second direction through the coupling 12. The lead screw 8 simultaneously drives the lead screw nut 7, the blocking claw 6, and the induction plate 25 to rotate in the second direction from the initial position and move along the lead screw 8 in the direction away from the motor 10. However, affected by the self-gravity of the blocking claw 6 and the restriction of the upper edge of the limit groove, the blocking claw 6 can only first move horizontally to the side of the spacer sleeve 18. After the edge of the lead screw nut 7 is caught inside the spacer sleeve 18, the chamfers on the lead screw nut 7 and the spacer sleeve 18 are self-locked by friction, overcoming the influence of the self-gravity of the blocking claw 6 and making the blocking claw 6 rotate back to the initial position in the second direction, that is, above the limit plate 15. At this time, the induction plate 25 is located at the front end of the signal emission hole of the second in-place sensor 24, blocking the signal of the second in-place sensor 24. When the second in-place sensor 24 detects that the distance between it and the induction plate 25 reaches a predetermined distance, the motor 10 automatically cuts off the power.

[0060] It should be noted that this application is not limited to the above embodiments. The above embodiments are only examples. Embodiments having the same structure and the same function and effect as the technical idea within the technical solution scope of this application are all included in the technical scope of this application. In addition, within the scope of not departing from the main idea of this application, various deformations that can be thought of by those skilled in the art are applied to the embodiments, and other ways constructed by combining some constituent elements in the embodiments are also included in the scope of this application.
