Description

Technical Field

[0001] The utility model relates to the technical field of fully mechanized mining equipment, in particular to intelligent fully mechanized mining equipment for coal mines. Background Art

[0002] Intelligent comprehensive mining equipment in coal mines includes fully automated coal mining machines, intelligent transportation systems, intelligent monitoring systems and safety devices. The intelligent monitoring system uses sensors, cameras and data analysis systems. The sensors continuously monitor the safety status of the environment, equipment and personnel, and provide real-time and accurate data for the intelligent monitoring system to help prevent accidents, optimize production processes, and ensure efficient and safe coal mine operations.

[0003] However, due to the large amount of dust during coal mining, the gas sensor is prone to clogging at the air inlet after a period of use, resulting in a decrease in the detection performance of the gas sensor, which cannot serve as an early warning for coal mine comprehensive mining. For this reason, we propose a coal mine intelligent comprehensive mining equipment to solve the existing problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model intercepts dust in the comprehensive mining tunnel of the coal mine by sleeve-fitting a filter cover on the outside of the air inlet end of the gas sensor, thereby avoiding the problem that the gas sensor detects the gas content in the comprehensive mining tunnel of the coal mine for a long time because there is a lot of dust inside the comprehensive mining tunnel of the coal mine, which causes blockage and affects the detection effect. The filter is automatically cleaned by a longitudinally moving brush, the equipment is stable in use, and the gas inside the comprehensive mining tunnel of the coal mine is effectively detected.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, the utility model proposes an intelligent comprehensive mining equipment for coal mines, comprising a gas sensor 1, a mounting plate 2, a motor 3, a collar 4 and a screw rod 18. The mounting plate 2 is sleeved on the outer side of the upper end of the gas sensor 1. A symmetrically distributed bearing bracket 14 is arranged on the upper end of the mounting plate 2. A screw rod 18 is rotatably inserted inside the bearing bracket 14. A torsion block 19 is arranged at one end of the screw rod 18. The threads on the outer wall of the screw rod 18 are relatively distributed. A symmetrically distributed nut 17 is rotatably sleeved on the outer wall of the screw rod 18. A slider 15 is arranged on the lower end of the nut 17. A sliding seat 16 is arranged on the upper end of the mounting plate 2. The slider 15 is slidably sleeved on the outer wall of the sliding seat 16. A jacket 1 20 and a jacket 2 21 are respectively arranged on the upper end of the nut 17. The jacket 1 20 and the jacket 2 21 are relatively distributed. The center of the jacket 1 20 is open, and the opening of the jacket 1 20 corresponds to the jacket 21.

[0021] Implementation steps based on Example 1: The gas sensor 1 needs to be fixed in a specified position when in use. During the comprehensive mining of coal mines, structures such as ventilation ducts of crossbeams are generally installed on the top of the underground mine tunnel to assist the comprehensive mining of coal mines. The torsion block 19 is rotated to drive the screw 2 18 to rotate, and the nut is driven to move relative to each other, thereby causing the jacket 1 20 and the jacket 2 21 to move relative to each other, clamping the outer wall of the fixing part on the top of the shaft, and conveniently fixing the gas sensor 1. There is no need to pre-install the base and the corresponding mounting bracket, and the disassembly and assembly process is easy and convenient.

[0022] like Figure 1-Figure 4As shown, compared with the first embodiment, the intelligent comprehensive mining equipment for coal mine proposed by the utility model further includes: a filter cover 5 is arranged at the lower end of the gas sensor 1, a mounting ring 8 is arranged at the upper end of the filter cover 5, the inner wall of the mounting ring 8 is sleeved on the side of the lower end of the gas sensor 1, a collar 4 is sleeved on the outer side of the filter cover 5, a motor 3 is arranged on one side of the gas sensor 1, a screw 6 is arranged at the lower end of the motor 3, a nut 9 is arranged at one end of the collar 4, the lower end of the screw 6 is rotatably inserted into the inside of the nut 9, a limiting ring 10 is arranged at the lower end of the screw 6, a sliding sleeve 13 is arranged at one end of the collar 4, a guide rod 7 is slidably inserted in the inside of the sliding sleeve 13, the upper end of the guide rod 7 is bent at ninety degrees, and the bent end is connected to the mounting plate 2, an air inlet end 12 is arranged at the lower end of the gas sensor 1, the air inlet end 12 is located inside the filter cover 5, and brushes 11 distributed in a ring array are arranged on the inner wall of the collar 4.

[0023] In this embodiment, during the use of the gas sensor 1, the air inlet end 12 inputs gas into the gas sensor 1, and during the process of gas flowing into the filter cover 5, dust in the gas is intercepted by the filter cover 5, thereby preventing dust from entering the air inlet end 12 and ensuring the smooth flow of the air inlet end 12. When the motor 3 is operating, it drives the screw 6 to rotate, and when the screw 6 rotates, it pushes the nut 9, thereby driving the ring 4 to descend, and the brush 11 brushes the outer wall of the filter cover 5 to separate the dust adhered to the outer wall of the filter screen. Moreover, the surface of the filter cover 5 is large, and even if part of it is blocked, it still ensures that the gas in the coal mine tunnel can effectively enter the air inlet end 12, so that the maintenance period of the filter cover 5 is long, and the filter cover 5 is easy to clean, thereby ensuring the stability of the use process of the gas sensor 1 and effectively detecting the gas in the coal mine shaft.
