[0002] In the hoisting / lowering transportation in a mine, in order to ensure the stability of the cage, a car arrester is often used to fix the position of the mine car / flatbed car in the cage. According to different driving methods, the car arrester can be divided into manual type, hydraulic type, electric type, pneumatic type, etc. At present, most mining enterprises still use manual car arresters, and the operator needs to open or close the car arrester beside the track. Frequent manual operations not only reduce work efficiency, increase the labor intensity of workers, but also easily cause potential transportation safety hazards. Therefore, it is particularly important to design a simple and easy-to-use self-service car arrester inside the cage.

[0003] In the prior art, some technicians install two groups of hydraulic push rods in the track to block the mine car in the cage by raising the hydraulic push rods; some technicians install a position sensor on the car arrester to locate the position of the mine car through the position sensor and send a signal to start the rotating claw to complete the anti-runaway operation. However, there are still problems in the prior art that the structure of the car arrester is not simple enough, the operation is not convenient enough, and it is difficult to adjust the car arresting position according to the length of the mine car.

[0004] In view of this, it is necessary to design an automatic car arrester inside the cage to solve the above problems. Summary of the Invention

[0005] In view of the technical problems existing in the background art, the present application provides an automatic car arrester inside the cage. The automatic car arrester inside the cage realizes car arresting by using a motor to drive the claw to rotate in front of / behind the wheel. At the same time, the rotation of the induction plate is used to block the signal of the position sensor to judge whether the claw rotates to the working position / initial position. This automatic car arrester inside the cage has strong anti-vibration ability, high safety factor, simple structure, can be linked with a car pusher to realize automatic car arresting, or can be remotely controlled by remote control. When maintaining or overhauling, only the outer shell needs to be removed, which is very convenient.

For example, two adjustable in-tank automatic car arresters are installed at the front end of the track in the cage, and two in-tank automatic car arresters provided in this application are installed at the rear end of the track. Before the mine car enters the cage, the two adjustable in-tank automatic car arresters at the front end of the track first rotate the arresting claws to the working position to block the forward movement of the mine car when the car pusher pushes the mine car into the cage. After all the vehicles for a single operation have entered, the two in-tank automatic car arresters at the rear end of the track then rotate the arresting claws to the working position to complete the vehicle fixation.

[0036] To solve the technical problems of cumbersome operation, time-consuming, and waste of labor costs of manual vehicle stoppers, the present application provides an automatic in-tank vehicle stopper. The automatic in-tank vehicle stopper realizes vehicle stopping by driving the blocking claw to rotate in front of / behind the wheel with a motor. At the same time, the rotation of the induction plate is used to block the signal of the in-place sensor to judge whether the blocking claw rotates to the working position / initial position.

[0037] Please refer to Figures 1 to 3 As shown, the automatic in-tank vehicle stopper provided by the present application includes a base 1. Along the central axis of the base 1, a motor 7, a speed reducer 8, a blocking claw 2, a shock absorber 14, an induction plate 17, and two in-place sensors 18 are arranged in sequence. The output end of the motor 7 is connected to the speed reducer 8. The output shaft of the speed reducer 8 is connected to one end of the first mating shaft 12 at the bottom of the blocking claw 2 through a coupling 10, and the blocking claw 2 is fixedly connected to the first mating shaft 12. The other end of the first mating shaft 12 is connected to the second mating shaft 16 of the induction plate 17 through the shock absorber 14, and the second mating shaft 16 is fixedly connected to the induction plate. First bearing seats 11 and second bearing seats 15 are respectively sleeved outside the first mating shaft 12 and the second mating shaft 16.

[0038] Further, in the embodiment of the present application, a cushion block 4 is provided on one side of the first mating shaft 12, and a limiting plate 13 is provided on the other side. In practical applications, the rotation of the first mating shaft 12 drives the blocking claw 2 to swing reciprocally in a direction perpendicular to the long side of the base 1. For the convenience of understanding, the direction in which the blocking claw 2 swings towards the limiting plate 13 is defined as the first direction, and the direction in which the blocking claw 2 swings towards the cushion block 4 is defined as the second direction. When the blocking claw 2 swings in the first direction, it falls above the limiting plate 13 fixedly connected to the base 1, that is, the working position, to achieve vehicle blocking. When it swings in the second direction, it falls above the cushion block 4 fixedly connected to the base 1, that is, the initial position, to achieve release. With such a setting, it is possible to prevent the blocking claw 2 from hitting the base 1 or the outer shell 3 during the swinging process, causing damage.

[0039] Further, in the embodiment of the present application, the two in-place sensors 18 are arranged in parallel with each other, and the signal emission directions of both are perpendicular to the plane where the induction plate 17 is located. Both of the two in-place sensors 18 are connected to the base 1 through a fixing plate 19.

[0040] Further, in the embodiment of the present application, in the initial state, the induction plate 17 is parallel to the plane where the base 1 is located; in the working state, the induction plate 17 is perpendicular to the plane where the base 1 is located. In the initial state, the induction plate 17 is at the same horizontal height as the second mating shaft 16 and the in-place sensors 18.

[0041] With such a setting, in the initial state, the signals emitted by the two in-place sensors 18 are blocked by the induction plate 17, and the operating platform receives a feedback signal, indicating that the blocking claw 2 is in the initial state; in the working state, the second mating shaft 16 drives the induction plate 17 to rotate around the second mating shaft 16 as the axis towards the second direction until the induction plate 17 is perpendicular to the base 1. The signals emitted by the two in-place sensors 18 pass through the two sides of the induction plate 17 respectively, and the operating platform receives a feedback signal, indicating that the blocking claw 2 is in the working state. In this way, the operator can remotely know the operating condition of the vehicle stopper and issue instructions according to the actual situation.

[0042] Further, the automatic in-tank vehicle stopper proposed in the present application further includes an outer shell 3 covering the base 1. An opening for the blocking claw 2 to extend out is provided on the outer shell 3. The bottom of the outer shell 3 is fixedly connected to the base 1 through a fixing angle steel 5 and bolts 6.

[0043] Further, in the embodiment of the present application, a fixing plate 9 fixedly connected to the base 1 is provided between the speed reducer 8 and the coupling 10 for fixing the speed reducer 8 and positioning the speed reducer 8 and the motor 7.

[0044] Further, in the embodiment of the present application, the base 1 is fixedly connected to the lower plate of the cage through bolts 6.

[0045] Furthermore, in the embodiments of the present application, copper sleeves are provided inside both the first bearing block 11 and the second bearing block 15. An oil injection port 20 is provided at 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.

[0046] Furthermore, in the embodiments of the present application, the shock absorption device 14 uses multiple disc springs in series. The series-connected disc springs have strong shock absorption and vibration damping capabilities, can withstand large loads with small deformations, and can achieve the effect of high compensation with low stroke.

[0047] Furthermore, the automatic in-tank car stopper provided in the present application can be linked with the car pusher to achieve automatic car stopping, or can be remotely controlled by remote control.

[0048] The working principle of the present application will be described below:

[0049] Please refer to Figure 4 As shown, two adjustable in-tank car stoppers are installed at the front end of the track inside the cage 23, and two in-tank car stoppers 21 provided in the present application are installed at the rear end of the track. Before the mine car 22 enters the cage 23, the two adjustable in-tank car stoppers at the front end of the track first rotate the blocking claws to the working position. When the car pusher pushes the mine car 22 into the cage 23, it blocks the forward movement of the mine car 22. After all the vehicles for a single operation have entered, the two in-tank car stoppers 21 at the rear end of the track then rotate the blocking claws 2 to the working position to complete the vehicle fixation.

[0050] Please refer to Figures 1 to 3 As shown, in the initial state, the blocking claw 2 is placed at the initial position on the cushion block 4. When the car stopping operation starts, the control console issues an instruction, the motor 7 is powered on and starts. The output shaft of the motor 7 rotates in the first direction. After the speed reducer 8 increases the torque, the output shaft of the speed reducer 8 drives the first mating shaft 12 to rotate through the coupling 10, so that the blocking claw 2 fixed on the first mating shaft 12 rotates together and lands on the limit plate, which is the working position. At the same time, the first mating shaft 12 drives the shock absorption device 14 and the second mating shaft 16 to rotate in the first direction as well, so that the induction plate 17 fixed on the second mating shaft 16 rotates to be parallel to the base 1. The signal of the in-place sensor 18 is blocked, and the blocking claw 2 is detected as being in the working state and a signal is fed back to the control console, and the mine car / flatbed car is fixed in the designated area.

[0051] After the ore car transportation ends, the console issues an instruction, and the motor 7 starts again. The output shaft of the motor 7 rotates in the second direction. Similarly, after the reducer 8 increases the torque, the output shaft of the reducer 8 drives the first mating shaft 12 to rotate through the coupling 10, so that the blocking claw 2 fixed on the first mating shaft 12 rotates back to the initial position. At the same time, the first mating shaft 12 drives the shock absorption device 14 and the second mating shaft 16 to rotate in the second direction as well, so that the induction plate 17 fixed on the second mating shaft 16 rotates to be perpendicular to the plane where the base 1 is located. The signals emitted by the two in-place sensors 18 are no longer blocked by the induction plate 17, and the blocking claw 2 is detected as the initial state and the signal is fed back to the console.

[0052] It should be noted that this application is not limited to the above embodiments. The above embodiments are only examples, and embodiments with the same structure and the same function and effect as the technical idea within the technical solution scope of this application are included in the technical scope of this application. In addition, within the scope of not departing from the gist 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.
