Description

Technical Field

[0001] This utility model relates to the field of underground blasting technology, specifically to an underground blasting post-mining vehicle. Background Technology

[0002] After deep-hole blasting in underground mines, multiple safety hazards exist at the work site: the blasting fumes contain toxic and harmful gases (such as carbon monoxide and nitrogen oxides), high concentrations of dust affect visibility and the respiratory system, loose rock masses may collapse secondary. Traditional hazard removal operations require personnel to enter the mining area to conduct gas detection and water spraying to suppress dust. At this time, the workers are completely exposed to the dangerous environment. If the blasting fumes do not completely dissipate, they may be poisoned and suffocated. Loose cuttings may slide and cause objects to fall. Loose rocks on the roof may fall at any time. This manual hazard removal method is not only inefficient, but also exposes the workers to extremely high safety risks. It is urgent to adopt mechanized methods to replace manual operations.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a mining vehicle for underground blasting, including a tracked chassis 1. A gas detection structure 2 is fixedly installed on one side of the inner wall of the tracked chassis 1, and a water tank 3 is fixedly installed on the other side of the surface of the tracked chassis 1. A water inlet 4 is fixedly connected to the surface of the water tank 3, and a plug 5 is inserted into the inner wall of the water inlet 4. Dust suppression structures 6 are installed through both sides of the inner wall of the water tank 3.

[0018] The tracked chassis 1, as a tracked walking mechanism, is widely used in engineering machinery, tractors and other field operation vehicles. Due to the harsh walking conditions, the walking mechanism is required to have sufficient strength and rigidity, as well as good travel and steering capabilities. The gas detection structure 2, in conjunction with the tracked chassis 1, can replace manual labor to detect the blasting fumes at the site. At the same time, the water tank 3, in conjunction with the dust suppression structure 6, can effectively suppress dust at the blasting site, ensuring the speed of blasting fume treatment. It can also effectively replace manual operation, ensuring the safety of site construction. It is highly practical. When the water tank 3 is short of water, the plug 5 can be pulled out and water can be poured in through the water inlet 4.

[0019] The gas detection structure 2 includes a hydraulic cylinder 21, which is fixedly connected to the inner wall of the tracked chassis 1. The piston rod end of the hydraulic cylinder 21 is fixedly equipped with a mounting groove 22. An insert block 23 is inserted into the inner wall of the mounting groove 22, and a gas detector 24 is mounted on the surface of the insert block 23.

[0020] When the gas detection structure 2 is needed, first insert the gas detector 24 along with the plug 23 that is attached to it into the mounting groove 22 to complete the installation of the gas detector 24. When the tracked chassis 1 enters the blasting smoke field, the hydraulic cylinder 21 can be opened as needed to control the piston rod to move up and down, thereby adjusting the longitudinal position of the gas detector 24, which can ensure a wide detection range and strong practicality.

[0021] The dust suppression structure 6 includes a first water pump 63, which is fixedly mounted on the surface of the water tank 3. One end of the first water pump 63 is fixedly connected to a nozzle 62 through a water outlet pipe 61, and the other end of the first water pump 63 is fixedly connected to an insertion pipe 64. The insertion pipe 64 is inserted into the water tank 3 and extends to the lower end of the inner cavity of the water tank 3.

[0022] Turn on the first water pump 63 to draw water from the water tank 3 through the insertion pipe 64, and then into the water outlet pipe 61 through the first water pump 63, and sprayed out through the nozzle 62. The nozzle 62 can be selected with a large spraying area to ensure the dust suppression effect.

[0023] A spray gun structure 7 is fixedly mounted on the side wall of the water tank 3, and the end of the spray gun structure 7 is connected to the inner wall of the water tank 3.

[0024] The spray gun structure 7 includes a support 71, which is fixedly mounted on the side wall of the water tank 3. A rotating shaft 73 is rotatably mounted through the inner wall of the support 71. A motor 72 is fixedly mounted on the side wall of the support 71. The motor shaft of the motor 72 is inserted into the inner wall of the support 71 and fixedly connected to one end of the rotating shaft 73. The motor shaft of the motor 72 is clearance-fitted with the inner wall of the support 71. A support cylinder 74 is fixedly mounted on the side wall of the rotating shaft 73. A spray gun 75 is tightly inserted into the inner wall of the support cylinder 74. A water supply hose 76 is fixedly connected to the side end of the spray gun 75. The water supply hose 76 is connected to a connecting pipe 78 through a second water pump 77. The second water pump 77 is fixedly mounted on the side wall of the water tank 3. The connecting pipe 78 passes through the water tank 3 and extends to the lower end of the inner cavity of the water tank 3.

[0025] The spray gun structure 7 can shoot out a water jet while maintaining a consistent range. In areas where the dust suppression structure 6 is difficult to handle, the spray gun structure 7 can effectively suppress dust and knock down loose gravel, ensuring safety underground. The motor 72 adjusts the rotation of the shaft 73, which in turn drives the spray gun 75 to rotate via the support cylinder 74. The nozzle orientation of the spray gun 75 is adjusted, and the water supply hose 76 can adaptively adjust with the displacement of the spray gun 75. The motor 72 is a servo motor, which can be programmed to rotate forward and backward or rotate slightly. After adjusting the orientation of the spray gun 75, the second water pump 77 is activated to draw water from the water tank 3 through the pipe 78 and into the water supply hose 76. The water is then sprayed out under high pressure through the spray gun 75, forming a water mist or a water jet. The nozzle of the spray gun 75 can be adjusted as needed to effectively suppress dust at higher altitudes and knock down loose gravel.

[0026] A bracket 8 is fixedly mounted on the side wall of the water tank 3, and a fan 9 is fixedly mounted on the inner wall of the bracket 8.

[0027] The bracket 8 ensures the stability of the fan 9, which can extract dust and send it outdoors with the help of flexible pipes to assist in dust suppression.
