Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a hydraulically driven integrated tunneling device for coal mines. Background Technology

[0002] Coal mining refers to the process of extracting coal resources from underground or open-pit coal mines. It is a complex and dangerous job that requires strict safety regulations and high technical requirements. With the continuous advancement of technology, the level of automation and intelligence in the coal mining process is constantly improving in order to reduce casualties and the incidence of mine accidents. Coal mining also poses challenges to environmental protection, requiring corresponding measures to reduce its impact on the environment and achieve the sustainable development and utilization of mineral resources. In the entire tunneling process of coal mining, the self-propelled tail section plays an important role in the transportation link.

[0003] Existing self-propelled conveyor tails cannot adjust their levelness in time after movement, which can easily cause the conveyor belt to deviate during subsequent coal transportation, thus affecting the service life of the conveyor belt. To address this, we propose a hydraulically driven integrated tunneling device for coal mines. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulically driven integrated tunneling device for coal mines, which can automatically adjust the level of the tunneling equipment to solve the problem that the existing self-moving tail cannot adjust its level in time after moving, and the conveyor belt is prone to deviate during subsequent coal transportation, thus affecting the service life of the conveyor belt.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal mine hydraulically driven integrated tunneling device, comprising a mobile host A, a connecting host, and a mobile host B, wherein connecting columns are installed at the four corners of the bottom of the connecting host, a hydraulic cylinder is installed at the bottom of the connecting column, a sliding column is installed on the output shaft of the hydraulic cylinder, the sliding column is sleeved on the outer surface of the connecting column, a horizontal seat is installed in the middle of the bottom of the connecting host, a steel ball is installed at the top of the horizontal seat via a pull rope, and an infrared ranging sensor is installed on the inner surface of the horizontal seat.

[0006] Preferably, a mobile host A is installed on one side of the connecting host, and a mobile host B is installed on the side of the connecting host away from the mobile host A. Mobile tracks are installed on the front and rear surfaces of both the mobile host A and the mobile host B.

[0007] Preferably, an anti-slip plate is installed at the bottom of the sliding column, and the lower surface of the anti-slip plate is provided with anti-slip teeth.

[0011] Preferably, the rotating shaft and the slider are connected by a threaded connection, and the slider is in frictional contact with the support frame.

[0012] Preferably, there are eight infrared ranging sensors, and the eight infrared ranging sensors are evenly distributed on the inner surface of the horizontal seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves the effect of automatically adjusting the level of the tunneling equipment by setting up a level seat, an infrared ranging sensor, a hydraulic cylinder and a steel ball. This solves the problem that existing self-propelled tail machines cannot adjust their level in time after moving, and the conveyor belt is prone to deviation during subsequent coal mine transportation. This reduces the probability of conveyor belt deviation and thus improves the service life of the conveyor belt.

[0015] 2. This utility model achieves the effect of adjusting the position of the machine body centerline by setting up a support frame, a transparent cover and an infrared sensor, so as to solve the problem that the existing machine tail centerline and the conveyor belt centerline are misaligned, which leads to conveyor belt misalignment, which in turn causes conveyor belt wear and affects the service life of the conveyor belt. It reduces the probability of conveyor belt misalignment, thereby improving the service life of the conveyor belt.

[0016] 3. This utility model achieves the effect of cleaning the transparent cover by setting up cleaning cotton, rotating shaft and moving frame, so as to solve the problem that the dust generated in the coal mining process is large and can easily contaminate the transparent cover, affecting the normal use of the infrared sensor. It reduces the probability of the transparent cover being contaminated, thereby ensuring the normal use of the infrared sensor. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, to achieve the above objectives, this utility model provides the following technical solution: a coal mine hydraulically driven integrated tunneling device, including a mobile host A1, a connecting host 2, and a mobile host B4. Connecting columns 12 are installed at the four corners of the bottom of the connecting host 2. A hydraulic cylinder 18 is installed at the bottom of the connecting column 12. A sliding column 19 is installed on the output shaft of the hydraulic cylinder 18. The sliding column 19 is sleeved on the outer surface of the connecting column 12. An anti-slip plate 20 is installed at the bottom of the sliding column 19. The lower surface of the anti-slip plate 20 is provided with anti-slip teeth. A horizontal seat 13 is installed in the middle of the bottom of the connecting host 2. A steel ball 16 is installed at the top of the horizontal seat 13 through a pull rope 15. An infrared ranging sensor 17 is installed on the inner surface of the horizontal seat 13. There are eight infrared ranging sensors 17 in total, and the eight infrared ranging sensors 17 are evenly distributed at the positions on the inner surface of the horizontal seat 13. The steel ball 16 is located by measuring the distance through the eight infrared ranging sensors 17.

[0027] The working principle of a coal mine hydraulically driven integrated tunneling device based on Embodiment 1 is as follows: After the device is installed, when it needs to be moved, the hydraulic cylinder 18 is activated, which drives the sliding column 19 upward, placing the moving track 5 on the ground. The moving track 5 then drives the moving host A1 and the moving host B4, thereby moving the device. After the device is moved to the place of use, the hydraulic cylinder 18 is activated, which drives the sliding column 19 downward, thus supporting the device. At the same time, the position of the steel ball 16 is measured by the infrared ranging sensor 17. When the steel ball 16 shifts to one side, the hydraulic cylinder 18 on the shifted side is controlled to adjust the level of the device, thus facilitating its use. Thus, the working process of the device is completed.

[0028] Example 2

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the coal mine hydraulically driven integrated tunneling device proposed in this utility model, compared with Embodiment 1, further includes: a mobile host A1 installed on one side of the connecting host 2, a mobile host B4 installed on the side of the connecting host 2 away from the mobile host A1, mobile tracks 5 installed on the front and rear surfaces of both the mobile host A1 and the mobile host B4, a support frame 3 installed on the top of the mobile host B4 near both the front and rear surfaces, infrared sensors 14 installed on both sides of the bottom of the support frame 3 for positioning the mobile tracks 5, a transparent cover 9 installed on the bottom of the support frame 3 on the outer surface of the infrared sensors 14, connecting plates 8 installed on both sides of the support frame 3, a rotating shaft 21 installed in the gap between the connecting plates 8, a micro motor 7 installed at one end of the rotating shaft 21, a slider 6 sleeved on the outer surface of the rotating shaft 21, a moving frame 11 installed at the bottom of the slider 6, a cleaning cotton 10 installed on the top of the moving frame 11 for cleaning the transparent cover 9, the rotating shaft 21 and the slider 6 are connected by a threaded connection, the slider 6 is in frictional contact with the support frame 3 to facilitate the movement of the slider 6.

[0030] In this embodiment, during movement, the edge of the coal mine conveyor belt is located by the infrared sensor 14. After the infrared sensor 14 detects the offset of the center line of the conveyor belt and the mobile host B4, the mobile track 5 drives the mobile host A1 and the mobile host B4 to rotate and move, thereby adjusting the usage angle of the connecting host 2 until the center line of the connecting column 12, the mobile host A1 and the mobile host B4 are in a straight line with the center line of the conveyor belt. Before use, the micro motor 7 is started, which drives the rotating shaft 21 to rotate. The rotating shaft 21 drives the slider 6 to move, the slider 6 drives the moving frame 11 to move, and the moving frame 11 drives the cleaning cotton 10 to move. The cleaning cotton 10 cleans the transparent cover 9 to prevent the transparent cover 9 from being contaminated, which would affect the performance of the infrared sensor 14.

[0031] The above specific embodiments are merely several preferred embodiments of this utility model.
