Description

Technical Field

[0001] The utility model belongs to the technical field of underground mine operation equipment, and in particular relates to a push-off type underground ore transport vehicle. Background Art

[0002] Underground ore trucks are mainly used in underground mines for loading, transporting and dumping operations. They are suitable for working in harsh working conditions and narrow tunnels. Traditional underground ore trucks usually use the method of lifting the bucket to achieve unloading. The problem is that the lifting height of the bucket is limited by the tunnel. When working in low tunnels, there is a problem that the bucket cannot be fully lifted, resulting in incomplete unloading. Even if the bucket is fully lifted, the friction between the material and the bucket still cannot achieve complete unloading.

[0003] Patent CN 115709674A discloses an underground ore transport vehicle for preventing incomplete material discharge, comprising a vehicle body with a hopper, a hydraulic cylinder capable of driving the hopper to tilt and discharge, and an ore-blocking unit for preventing ore in the hopper from falling, a trapezoidal protrusion being arranged on the bottom surface of the inner cavity of the hopper, and two push plate units and a power unit for driving the two push plate units to move relative to or backwards; a power unit and a push plate unit are arranged, and the pulling force generated when the hydraulic cylinder drives the hopper to tilt and discharge is used to drive the two push plate units to move together (i.e., relative movement), and push the ore in the corner to the middle part of the hopper for discharge, and at the same time, in the process of the hopper being restored to a horizontal level by the hydraulic cylinder, the power unit drives the two push plate units to move backwards and return to their original positions by relying on its own gravity, which is conducive to the complete discharge of the underground ore transport vehicle, but it is still necessary to lift and tilt the hopper to discharge the material first, and the unloading problem during operation in low tunnels cannot be solved. Since the expansion of tunnels requires enormous manpower, financial resources and material resources, it is urgent to study an underground ore transport vehicle that can operate in low tunnels and unload materials completely. Utility Model Content

[0004] In order to solve the existing technical problems, the utility model provides a push-unloading underground ore transport vehicle, which drives a push plate to slide on a hopper through an oil cylinder and completes the unloading operation by a push-plate push-unloading method.

[0005] The technical solution of the utility model is: a push-unload type underground ore transport vehicle, comprising a hopper mounted on a vehicle body, the hopper being provided with a push plate and a first oil cylinder for driving the push plate to move, the two ends of the first oil cylinder being respectively hinged on the hopper and the push plate, the push plate being arranged on the inner side of the front wall of the hopper, a material baffle plate being installed at the rear of the hopper, the upper part of the material baffle plate and the hopper being fixedly connected by a hinge, a second oil cylinder being arranged between the hopper and the material baffle plate, the two ends of the second oil cylinder being respectively hinged on the hopper and the material baffle plate.

[0006] Furthermore, the push plate includes a main push plate located in the middle and side push plates located on the left and right sides of the main push plate, which are connected to each other. The side push plates are arranged on the rear side of the main push plate, a slider is arranged on the outer wall of the side push plate, and a groove is arranged on the hopper, the groove is adapted to the slider, and the push plate slides along the groove of the hopper through the slider.

[0007] Furthermore, the push plate is adapted to the shape of the inner wall of the hopper, the push plate is in contact with the bottom and side walls of the hopper, and the front portion of the push plate extends upward to above the front wall of the hopper.

[0008] Furthermore, a scraper is arranged on the lower side of the push plate, the scraper is fixed to the lower end of the main push and separation plate, and the scraper is in contact with the bottom of the hopper.

[0009] Furthermore, a sensor for detecting whether the material baffle plate is in an open state or a closed state is arranged on the material baffle plate.

[0010] The working principle of a push-unloading underground ore transport vehicle of the utility model is as follows: when unloading is required, the operator controls the second oil cylinder to push out the operation, driving the baffle plate to open from the rear of the hopper, realizing the opening of the discharge port of the hopper, and at the same time, the sensor detects whether the baffle plate is fully opened to give the operator a reminder, and then controls the first oil cylinder to push out the operation, driving the push plate to slide toward the rear of the hopper, pushing the material in the hopper to the rear side of the hopper, and then pushing it out from the discharge port to realize the unloading operation of the hopper. When the unloading is completed, the first oil cylinder is controlled to retract the operation, so that the push plate slides from the tail of the hopper to the front of the hopper to reset, so as to prepare for a new hopper loading operation, and the second oil cylinder is controlled to retract the operation, so that the baffle plate is closed, and at the same time, the sensor detects whether the baffle plate is fully closed to give the operator a reminder.

[0011] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0012] (1) The utility model uses a pushing unloading method to unload materials. The material in the hopper is pushed directly to the discharge port of the hopper by a push plate to complete the unloading. The hopper can be unloaded without lifting it, which solves the unloading problem in low tunnels and avoids the problem of incomplete unloading caused by the friction between the material and the hopper in the lifting unloading method. It avoids the high consumption of manpower, material and financial resources for expanding the tunnel, greatly saves costs, has a simple structure, and is easy to operate.

[0013] (2) The utility model provides a scraper on the push plate, which facilitates the complete unloading of the hopper material and reduces the friction between the push plate and the hopper. The scraper is easy to replace after being worn, and the use cost and maintenance cost are low. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Example 1

[0022] Reference Figure 1-5 A push-unloading underground ore transport vehicle comprises a hopper 1 mounted on a vehicle body 2, a push plate 4 and a first oil cylinder 3 for driving the push plate 4 to move are mounted on the hopper 1, two ends of the first oil cylinder 3 are respectively hinged on the hopper 1 and the push plate 4, the push plate 4 is arranged on the inner side of the front wall of the hopper 1, a baffle plate 5 is installed at the rear of the hopper 1, the upper part of the baffle plate 5 and the hopper 1 are fixedly connected by a hinge, a second oil cylinder 6 is arranged between the hopper 1 and the baffle plate 5, and two ends of the second oil cylinder 6 are respectively hinged on the hopper 1 and the baffle plate 5.

[0023] The first oil cylinder 3 drives the push plate 4 to move backward, thereby pushing the material in the hopper 1 to the discharge port at the rear of the hopper 1. The unloading operation of the hopper 1 can be completed without lifting the hopper 1, and the operation is simple. The second oil cylinder 6 drives the baffle plate 5 to open or close. When the baffle plate 5 is opened, the discharge port of the hopper 1 is opened, and the hopper 1 is ready to unload; when the baffle plate 5 is closed, the discharge port is closed, and the material in the hopper 1 is blocked by the baffle plate 5 and cannot be unloaded.

[0024] Further, the push plate 4 includes a main push plate 11 in the middle and side push plates 12 on the left and right sides of the main push plate 11, which are connected to each other. The side push plates 12 are arranged at the rear side of the main push plate 11, and a slider 8 is arranged on the outer wall of the side push plate 12. A groove 9 is arranged on the hopper 1, and the groove 9 is adapted to the slider 8. The push plate 4 slides along the groove 9 of the hopper 1 through the slider 8. Through the cooperation of the slider 8 and the groove 9, the sliding connection between the push plate 4 and the hopper 1 is realized, so that the push plate 4 can slide smoothly along the groove 9 in the front-rear direction inside the hopper 1.

[0025] Furthermore, the push plate 4 is adapted to the shape of the inner wall of the hopper 1 , the push plate 4 is in contact with the bottom and side walls of the hopper 1 , and the front portion of the push plate 4 extends upward to above the front wall of the hopper 1 .

[0026] The push plate 4 is adapted to the shape of the hopper 1, so that when the push plate 4 moves backward to push the material in the hopper 1 to the rear side of the hopper 1, the material will not enter the front side of the push plate 4 from the side and bottom of the push plate 4. On the one hand, the material can be completely unloaded by pushing and unloading, and on the other hand, it can prevent the push plate 4 from being unable to return to its original position after the unloading is completed due to the material entering the front side of the push plate 4, thereby reducing the loading capacity of the hopper 1.

[0027] Furthermore, a scraper 10 is provided at the lower side of the push plate 4, and the scraper 10 is fixed at the lower end of the main push and separation plate 11, and the scraper 10 contacts the bottom of the hopper 1. The scraper 10 reduces the friction between the push plate 4 and the hopper 1, and when the scraper 10 is worn due to excessive pushing of materials, the scraper 10 can be directly replaced, which is convenient to operate and has low maintenance cost.

[0028] Further, a sensor 7 for detecting whether the baffle plate 5 is in an open state or a closed state is provided on the baffle plate 5. The sensor 7 detects the open and closed states of the baffle plate 5 to ensure that the baffle plate 5 is in an open state when the push plate 4 slides to push the material.

[0029] The working principle of a push-unloading underground ore transport vehicle of the utility model is as follows: when unloading is required, the operator controls the second oil cylinder 6 to push out the operation, driving the baffle plate 5 to open from the rear of the hopper 1, realizing the opening of the discharge port of the hopper 1, and at the same time, the sensor 7 detects whether the baffle plate 5 is fully opened to give a reminder to the operator, and then controls the first oil cylinder 3 to push out the operation, driving the push plate 4 to slide toward the rear of the hopper 1, pushing the material in the hopper 1 to the rear side of the hopper 1, and then pushing it out from the discharge port to realize the unloading operation of the hopper 1. When the unloading is completed, the first oil cylinder 3 is controlled to retract the operation, so that the push plate 4 slides from the rear of the hopper 1 to the front of the hopper 1 to reset, so as to prepare for a new loading operation of the hopper 1, and the second oil cylinder 6 is controlled to retract the operation, so that the baffle plate 5 is closed, and at the same time, the sensor 7 detects whether the baffle plate 5 is fully closed to give a reminder to the operator.
