Description

Technical Field

[0001] This utility model relates to the technical field of mining weighing devices, specifically to a weighing and monitoring device for a tracked mining car. Background Technology

[0002] Mining trucks are mainly used for transportation in various fields such as mines, quarries, large-scale engineering construction, and special environments. They have strong load-bearing capacity and the ability to adapt to harsh environments. After loading, the mining trucks need to be parked in the weighing area on the weighing track for weighing to check the load weight. Due to the large load capacity and inertia of the mining trucks during travel, a longer braking distance is required to stop them. In actual operation, mining trucks often slide out of the weighing area when parking, causing part of the truck body to fall into the non-weighing area, resulting in a deviation between the parking position and the set position. When the parking position of the mining truck is deviated, it will lead to inaccurate weighing. In order to make the weighing more accurate, the driver often needs to spend more time and effort to control the speed in advance to park the mining truck in the set weighing position, resulting in low weighing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a track-mounted mine car weighing and monitoring device that enables the mine car to stop more accurately at the set position, making the weighing more accurate and improving the weighing efficiency.

[0004] This utility model includes a weighing track connected in series with a regular track. A weighing platform for weighing mine cars on the weighing track is installed at the lower part of the weighing track. An indicator light for indicating that the mine car has reached its destination is provided on one side of the weighing track. An installation groove is provided on the weighing track and the weighing platform, and a monitoring mechanism for monitoring whether the mine car has reached its destination is installed in the installation groove. The monitoring mechanism includes a car-stopping plate installed on one side of the installation groove, and a trigger plate installed on the opposite side of the car-stopping plate. The car-stopping plate and the trigger plate are connected in series in the circuit of the indicator light.

[0005] Preferably, the wheel stop plate is movably installed in the mounting groove, with the upper end of the wheel stop plate extending out of the mounting groove and the lower end of the wheel stop plate rotatably mounted on the rotating pin; a load spring is fixedly connected to the lower part of the wheel stop plate.

[0006] Preferably, the upper surface of the wheel stop plate, in the area exposed above the mounting groove, is provided with an anti-slip mechanism.

[0007] Preferably, the upper end of the wheel stop plate has a rounded chamfer.

[0008] Preferably, the weighing track is located above the vehicle stop plate and is provided with a clearance ramp for avoiding the vehicle stop plate.

[0009] Preferably, the trigger plate is rotatably installed in the mounting groove on the side opposite to the vehicle stop plate, and a compression spring is fixedly connected to the lower part of the trigger plate, with the other end of the compression spring fixedly connected to the inner wall of the mounting groove.

[0010] Preferably, a limiting step is formed on the inner wall of the mounting groove, above the trigger plate, to limit the movement of the trigger plate.

[0011] Preferably, the trigger plate has a rounded chamfer on one side of the vehicle stop plate.

[0012] In summary, this utility model has the following beneficial effects:

[0013] A monitoring mechanism is installed on the weighing track. The monitoring mechanism includes a stop plate and a trigger plate arranged opposite each other. The stop plate, trigger plate, and indicator light form a series circuit. When the mine car travels to the weighing area, the mine car wheels press against the stop plate. The resistance of the stop plate stops the mine car in the designated weighing area. At the same time, the stop plate rotates downward and contacts the trigger plate. The series circuit formed by the stop plate, trigger plate, and indicator light is closed, and the indicator light illuminates, indicating to the driver that the mine car has arrived at the designated position and can be weighed. This device ensures that the mine car stops at the predetermined position before weighing each time, making the weighing more accurate. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] The orientations mentioned in this specification are based on the orientation of the track mine car weighing and monitoring device of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0022] like Figures 1 to 5 As shown, a track-mounted mine car weighing monitoring device includes a weighing track 1 connected in series with a regular track 7. A weighing platform 6 is installed at the lower part of the weighing track 1 to weigh the mine car 5 on the weighing track 1. When the mine car 5 stops at a specific position on the weighing track 1, the weighing platform 6 can weigh the corresponding weight. An indicator light 2 is provided on one side of the weighing track 1 to indicate that the mine car 5 has reached its position. An installation groove 3 is provided on one side of the weighing track 1 and the weighing platform, and a monitoring mechanism 4 for monitoring whether the mine car 5 has reached its position is installed in the installation groove 3.

[0023] The monitoring mechanism 4 includes a car stop plate 401 installed on one side of the mounting groove 3, and a trigger plate 402 installed on the opposite side of the car stop plate 401. The car stop plate 401 and the trigger plate 402 are connected in series in the circuit of the indicator light 2. Only the contact surfaces of the car stop plate 401 and the trigger plate 402 are conductors, and the rest are covered with insulating material. When the car stop plate 401 rotates downward under the pressure of the mine car 5 wheel 501 and comes into contact with the trigger plate 402, the conductor parts between the two come into contact and form a closed circuit.

[0024] The wheel stop plate 401 is movably installed in the mounting slot 3. The upper end of the wheel stop plate 401 is inclined upward and extends out of the mounting slot 3, while the lower end of the wheel stop plate 401 is rotatably mounted on the rotating pin 403. A load spring 404 is fixedly connected to the lower part of the wheel stop plate 401, and the other end of the load spring 404 is fixedly mounted on the weighing platform 6. Under the action of external force, the wheel stop plate 401 can rotate downward around the rotating pin 403. When the external force is removed, the wheel stop plate 401 springs back to its initial position under the action of the load spring 404. The upper surface of 01, in the area exposed above the mounting groove 3, is provided with an anti-slip mechanism 405; the upper end of the car stop plate 401 is provided with an arc-shaped chamfer; the weighing rail 6 is located on the upper side of the car stop plate 401 and is provided with a clearance ramp 406 for avoiding the car stop plate 401. The clearance ramp 406 does not hinder the movement of the car stop plate 401 on the one hand, and restricts the car stop plate 401 within a specific movement space on the other hand, so that after the car stop plate 401 rebounds, it can maintain a suitable tilt angle, which is convenient for the wheels 501 of the mine car 5 to run over.

[0025] The trigger plate 402 is rotatably installed in the mounting groove 3 on the side opposite to the vehicle stop plate 401. A compression spring 407 is fixedly connected to the lower part of the trigger plate 402, and the other end of the compression spring 407 is fixedly connected to the inner wall of the mounting groove 3. Under the action of external force, the trigger plate 402 can rotate downward. When the external force is removed, it will spring back to the initial position under the action of the compression spring 407. On the inner wall of the mounting groove 3, above the trigger plate 402, a limiting step 408 is formed to limit the trigger plate 402. The limiting step 408 restricts the trigger plate 402 within a specific movement space, so that the trigger plate 402 can maintain a horizontal state after springing back, which is convenient for the next contact with the vehicle stop plate 401. The trigger plate 402 has an arc-shaped chamfer on one side of the vehicle stop plate 401. When the vehicle stop plate 401 contacts the trigger plate 402, the arc-shaped chamfer makes the contact surface between the two larger.

[0026] Working principle: When the mine car 5 travels to the vicinity of the monitoring mechanism 4, the mine car 5 decelerates, and the wheels 501 of the mine car 5 slowly press against the car stop plate 401. The resistance of the car stop plate 401 causes the mine car 5 to stop. At the same time, the car stop plate 401 rotates downward and contacts the trigger plate 402. The series circuit formed by the car stop plate 401, the trigger plate 402 and the indicator light 2 is closed, and the indicator light 2 lights up, indicating that the mine car 5 has traveled to the correct position and the mine car 5 has stopped. The mine car 5 is then accurately weighed. After the weighing is completed, the mine car 5 continues to travel forward, and the wheels 501 gradually move away from the car stop plate 401. The car stop plate 401 rebounds under the action of the load spring 404 and leaves the contact surface with the trigger plate 402, causing the series circuit of the indicator light 2 to break and the indicator light 2 to turn off. It should be noted that the size of the mounting groove 3 is much smaller than the diameter of the wheel 501, and it is set on the weighing rail 1 on one side. Furthermore, the car stop plate 401 always provides support under the wheel 501. Therefore, the mounting groove 3 will not affect the movement of the mine car 5.

[0027] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
