Abstract
Description
Technical Field
[0001] This invention relates to the field of mining auxiliary equipment, and more specifically to a mobile device for safe conveying and blocking in mine ore chutes. Background Technology
[0002] Once a mine pass becomes blocked for any reason, it will seriously affect the normal operation of mine production, and may even cause a shutdown. Currently, the main methods for dealing with mine pass blockages include mechanical prying, drilling and blasting, blasting with explosive charges suspended by bamboo poles, blasting with explosive charges suspended by hydrogen balloons, and mining rockets. These methods can effectively deal with mine pass blockages to a certain extent, but they still have significant safety risks and limitations.
[0003] Due to the explosive nature of blasting, there are certain safety hazards in the actual dredging process of mine ore chutes. The mechanical prying method is limited by the adjustment arm of the pneumatic hammer, which makes it impossible to dredge the mine ore chutes further. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] Reference Figures 1 to 3As shown, this embodiment provides a mobile safety device for clearing blockages in a mine chute, including a frame 1. Two drive wheels 2 are installed at one end of the frame 1, and two tension driven wheels 4 are installed at the other end of the frame 1. Tracks are wound around the drive wheels 2 and tension driven wheels 4 on the same side. A turntable 6 is rotatably connected to the top surface of the frame 1. An adjusting arm 7 is fixedly connected to the top surface of the turntable 6. A multi-stage telescopic mechanism 9 is installed at the movable end of the adjusting arm 7, and a pneumatic hammer 10 is installed at the movable end of the multi-stage telescopic mechanism 9.
[0023] This invention increases the depth of the air hammer 10 during the hammering process by installing a multi-stage telescopic mechanism 9 at the movable end of the adjusting arm 7. This ensures that the air hammer 10 travels as much as possible during the dredging of the ore pass. The angle of the air hammer 10 is adjusted by the adjustment arm 7 in conjunction with the rotation of the turntable 6 to adjust the dredging position of the air hammer 10. The movement of the entire device is achieved through the combined action of the drive wheel 2, the tension driven wheel 4, and the track, which allows the entire device to move in the ore pass, making the dredging of the ore pass more convenient and faster.
[0024] The scheme is further optimized. The multi-stage telescopic mechanism 9 includes a first lifting sleeve 901, a second lifting sleeve 902 that is slidably connected to the inner side of the first lifting sleeve 901, a third lifting sleeve 903 that is slidably connected to the inner side of the second lifting sleeve 902, a fourth lifting sleeve 904 that is slidably connected to the inner side of the third lifting sleeve 903, the top of the fourth lifting sleeve 904 that is fixedly connected to one side of the bottom of the lifting plate 2, a vertical conveying part that is slidably connected to the outer wall of the first lifting sleeve 901 away from the lifting plate 2, and a lifting drive part that is provided between the first lifting sleeve 901, the second lifting sleeve 902, the third lifting sleeve 903, and the fourth lifting sleeve 904.
[0025] The scheme is further optimized. The lifting drive unit includes a second threaded block 9021 fixedly connected to the inner sidewall of the bottom of the second lifting sleeve 902, a third threaded block 9031 fixedly connected to the inner sidewall of the bottom of the third lifting sleeve 903, and a fourth threaded block 6031 fixedly connected to the inner sidewall of the bottom of the fourth lifting sleeve 904. The center thread of the second threaded block 9021 is threadedly connected to a first lead screw sleeve 905. The outer side of the bottom of the first lead screw sleeve 905 is fixedly connected to a first sliding sleeve 9051. The inner side of the first sliding sleeve 9051 is rotatably connected to the outer side of the third threaded block 9031. The inner side of the first lead screw sleeve 905 is vertically slidably connected to a second... The second lead screw sleeve 906 has a second sliding sleeve 9061 fixedly connected to its bottom outer side. The inner side of the second sliding sleeve 9061 is rotatably connected to the outer side of the second threaded block 9021. The outer side of the second lead screw sleeve 906 is threadedly connected to the inner side of the third threaded block 9031. The inner side of the second lead screw sleeve 906 is vertically slidably connected to a third lead screw 907. The outer side of the third lead screw 907 is threadedly connected to the inner side of the second threaded block 9021. The bottom of the third lead screw 907 is rotatably connected to the bottom center of the first lifting sleeve 901. The third lead screw 907 is shaft-connected to a telescopic motor 8, which is fixedly connected to the first lifting sleeve 901.
[0026] By controlling the rotation of the telescopic motor 8, the telescopic motor 8 drives the third lead screw 907 to rotate. Since the third lead screw 907, the second lead screw sleeve 906, and the first lead screw sleeve 905 are vertically slidingly connected, the fourth lifting sleeve 904 and the first lead screw sleeve 905 will also rotate accordingly, thereby driving the corresponding first lifting sleeve 901, second lifting sleeve 902, third lifting sleeve 903, and fourth lifting sleeve 904 to achieve relative displacement, thereby driving the air hammer 10 to clear the blockage at a deeper depth. This connection method is more robust than other connection methods, which can further ensure that the air hammer 10 can stably break up the blockage.
[0027] The scheme is further optimized so that the drive wheel 2 shaft is connected to the drive motor 201, and the drive motor 201 is mounted on the frame 1.
[0028] By controlling the forward and reverse rotation and different speeds of different drive motors 201, the entire device can be controlled to perform steering operations.
[0029] In a further optimized design, a support wheel 102 is attached to the inner side of the track, and a support rod 101 is rotatably connected to the support wheel 102. The support rod 101 is fixedly connected to the frame 1.
[0030] The scheme is further optimized. A top mounting plate 103 is installed on the top surface of the frame 1. A ring guide rail 601 is coaxially fixedly connected to the bottom surface of the turntable 6. The ring guide rail 601 is rotatably engaged with the top mounting plate 103. A rotary motor 11 is installed on the top mounting plate 103. The output shaft of the rotary motor 11 passes through the top mounting plate 103 and is connected to a gear 1101. The gear 1101 meshes with the side wall of the turntable 6.
[0031] By controlling the operation of the rotating motor 11, the turntable 6 can be driven to rotate on the mounting plate 103, thereby achieving the purpose of adjusting the position of the entire adjusting arm 7. In this embodiment, the adjusting arm 7 can be a robotic arm or the loading robotic arm of an excavator.
[0032] In a further optimized design, two tension driven wheels 4 are connected to a rotating shaft 401. One end of a shock absorber 5 is rotatably connected to the rotating shaft 401, and the other end of the shock absorber 5 is rotatably connected to the frame 1. Driven wheels 3 are attached to the inner side of the track and are distributed at the front and rear ends of the frame 1.
[0033] The combination of shock absorber 5 and rotating shaft 401 ensures that the entire device adapts to the uneven terrain when moving in the ore pass, improving the adaptability of the device during travel.
