Air-controlled fence control group for comprehensive tunneling

Abstract

This invention provides a pneumatically controlled fence control group for tunnel boring machines, relating to the field of control group technology, including road passages. After the centralized control system is implemented, personnel control the opening and closing of the fence from a fixed, safe position, eliminating the need for frequent movement along vehicle auxiliary transport routes, thus ensuring the safety of personnel operating the fence and achieving "safety without human intervention." With the centralized control system, shift leaders can closely monitor the on-site safety production situation, ensuring smooth and safe production. This solves the problem of personnel being easily collided with vehicles during operation, which increases the risk of vehicle accidents. Furthermore, manually opening the fence is inefficient, and automatically opening the fence using sensors is prone to errors, leading to lower safety. During use, collisions between vehicles and the fence can cause damage, increasing maintenance costs.

Description

Technical Field

[0001] This invention relates to the field of control group technology, and particularly to a pneumatically controlled fence control group for tunnel boring machines. Background Art

[0002] The tunneling team is currently working on the head chamber excavation project. According to statistics from the actual production situation on site, an average of 32 muck removal trips are required per shift. The frequent entry and exit of auxiliary transport vehicles pose a greater challenge to the safety management of the working face.

[0003] However, regarding the current pneumatic fence control group for fully mechanized tunneling:

[0004] Personnel are easily collided with by vehicles during operation, which increases the risk of vehicle accidents. Furthermore, opening the fence manually is inefficient, and automatically opening the fence using an electric sensor is prone to failure due to sensor malfunction, resulting in low safety. During use, when a vehicle collides with the fence, it can damage the fence, leading to increased maintenance costs. Summary of the Invention

[0005] In view of this, the present invention provides a pneumatic fence control group for tunneling, which includes an activation fence A. By activating fence A, the pneumatic fence A allows for initial fixation via ground stakes. To ensure the base's stability, a first fixing seat is pulled to unfold it and then secured with ground stakes. This first fixing seat enhances the base's stability and improves its practicality. Simultaneously, controlling the opening and closing of the first fence involves rotating a motor. The meshing of the first and second gears enables the opening and closing of the first fence. When a vehicle collides with the second fence, a spring provides cushioning, and two elastic blocks also contribute to the cushioning effect, thus enhancing the overall cushioning performance.

[0006] With the auxiliary part, after the base is installed, it can be fixed again by connecting the connecting seat to the base, and then fixing the second fixing seat to the surrounding wall. Then, rotating the threaded tube can tighten the base and ensure the strength of the base.

[0007] The purpose and effectiveness of the pneumatically controlled fence control group used in fully mechanized tunneling are achieved by the following specific technical means:

[0008] This invention provides a pneumatically controlled fence control group for tunneling, specifically including: a road passage; the road passage consists of a main retreat passage A, a main retreat passage B, a transport passage, a return passage, an auxiliary retreat passage A, and an auxiliary retreat passage B, wherein the main retreat passage A, main retreat passage B, transport passage, return passage, auxiliary retreat passage A, and auxiliary retreat passage B are arranged in a grid pattern.

[0009] The road passage is equipped with pneumatic fence A, ordinary fence, pneumatic fence B, and control components.

[0010] The pneumatic fence A consists of a base, a first guide rod, a first fixed seat, a connecting rod, a first gear, a motor, a second gear, a first fence, a second guide rod, a second fence, a spring, and an elastic block. The base is fixed to the ground, and four first guide rods are slidably connected to the base. A first fixed seat is welded to each of the two first guide rods on the left and the two first guide rods on the right. The two first fixed seats are auxiliary fixing structures for the base.

[0011] Two connecting rods are rotatably connected to the base, and both connecting rods are welded to the first fence.

[0012] The first gear is mounted on one of the connecting rods at the top;

[0013] A motor is mounted on the base, and a second gear is mounted on the motor's rotating shaft. The second gear meshes with the first gear.

[0014] The first fence is slidably connected to four second guide rods, one end of each second guide rod is welded to the second fence, and each second guide rod is fitted with a spring for the second fence to return to its forward position.

[0015] The second fence has two elastic blocks symmetrically attached to its front end, both of which are made of rubber.

[0016] When fixing, the base can first be fixed with ground nails. To ensure the stability of the base, the first fixing seat needs to be pulled out and then fixed with ground nails. The fixing of the first fixing seat can strengthen the fixing effect of the base, thus improving the stability and practicality of the base.

[0017] When controlling the opening and closing of the first fence, the motor can be rotated. The opening and closing of the first fence can be achieved through the meshing transmission of the second gear and the first gear.

[0018] When a vehicle collides with the second fence, the spring provides cushioning, and at the same time, the two elastic blocks also provide cushioning, thus improving the cushioning effect through double cushioning.

[0019] Two auxiliary parts are installed on the base;

[0020] The auxiliary part consists of a second fixed seat, a connecting shaft, a threaded pipe, and a connecting seat, with the connecting seat rotatably connected to the base.

[0021] The second fixing seat is fixed to the wall. A connecting shaft is welded to the second fixing seat. A threaded pipe is rotatably connected to the connecting shaft. The threaded pipe is threadedly connected to the connecting seat.

[0022] After the base is installed, it can be fixed again through the auxiliary part. Connect the connecting seat to the base, then fix the second fixing seat to the surrounding wall, and then rotate the threaded tube to tighten the base and ensure the strength of the base.

[0023] The control unit consists of control ball A, control ball B, control ball C, control ball D, speaker A, speaker B, speaker C and controller. Control ball A, control ball B, control ball C, control ball D, speaker A, speaker B, speaker C and controller are all installed on the road passage.

[0024] The control ball A is located at the position of the main retraction channel A.

[0025] The control ball B is located in the loading area.

[0026] The control ball C is located at the position of the pneumatic fence A, and a speaker A is also located at the position of the pneumatic fence A.

[0027] The control ball D is located at the position of the ordinary fence, and a speaker B and a speaker C are installed at the control ball D.

[0028] The auxiliary retreat channel B is equipped with a loading area; a safety zone is set up on the road channel, where the operator is located. A controller is installed in the safety zone, and the controller is electrically connected to control ball A, control ball B, control ball C, control ball D, speaker A, speaker B and speaker C. The controller is also electrically connected to the motor.

[0029] Beneficial effects

[0030] Through the settings in the control section:

[0031] 1. Economic benefits: Based on 32 loading trips per shift, using ordinary safety barriers requires at least 0.5 minutes to open and close each time, and at least 48 times per shift, which takes about 24 minutes. Using pneumatic safety barriers can save this time, reduce wasted time, and improve work efficiency.

[0032] 2. Safety benefits: After the centralized control system is used, personnel can control the opening and closing of the fence from a fixed safe position, without having to frequently walk in the auxiliary transportation route of the vehicle, which ensures the safety of personnel opening and closing the fence and realizes "safety without personnel"; after using the centralized control system, the shift leader can closely monitor the on-site safety production situation and ensure the smooth progress of safe production.

[0033] 3. It has formed a prototype of automated and intelligent management of tunneling faces, laying the foundation for further development of automation and intelligence.

[0034] By setting up pneumatic fence A, the base can first be fixed with ground stakes during installation. To ensure the base's sturdiness, the first fixing seat needs to be pulled out and then fixed with ground stakes. This fixation of the first fixing seat strengthens the base's stability and improves its practicality. Simultaneously, controlling the opening and closing of the first fence involves rotating the motor. The meshing of the first and second gears enables the opening and closing of the first fence. When a vehicle collides with the second fence, a spring provides cushioning, and two elastic blocks also contribute to the cushioning effect. This double cushioning enhances the overall buffering performance.

[0035] With the auxiliary part, after the base is installed, it can be fixed again by connecting the connecting seat to the base, and then fixing the second fixing seat to the surrounding wall. Then, rotating the threaded tube can tighten the base and ensure the strength of the base. Attached Figure Description

[0060] Example 2:

[0061] Based on Example 1, such as Figure 3 and Figure 4As shown, it also includes: a pneumatic fence A4, which is composed of a base 401, a first guide rod 402, a first fixed seat 403, a connecting rod 404, a first gear 405, a motor 406, a second gear 407, a first fence 408, a second guide rod 409, a second fence 410, a spring 411, and an elastic block 412. The base 401 is fixed to the ground, and four first guide rods 402 are slidably connected to the base 401. A first fixed seat 403 is welded to each of the two first guide rods 402 on the left and the two first guide rods 402 on the right. The two first fixed seats 403 are auxiliary fixing structures for the base 401.

[0062] Two connecting rods 404 are rotatably connected to the base 401, and both connecting rods 404 are welded to the first fence 408.

[0064] A motor 406 is mounted on the base 401, and a second gear 407 is mounted on the rotating shaft of the motor 406. The second gear 407 meshes with the first gear 405.

[0065] The first fence 408 is slidably connected to four second guide rods 409. The front end of each of the four second guide rods 409 is welded to the second fence 410. Each of the four second guide rods 409 is fitted with a spring 411 for the second fence 410 to return to its forward position.

[0066] Among them, two elastic blocks 412 are symmetrically attached to the front end of the second fence 410, and both elastic blocks 412 are made of rubber.

[0067] When fixing, the base 401 can first be fixed with ground nails. In order to ensure the stability of the base 401, the first fixing seat 403 needs to be pulled. After the first fixing seat 403 is unfolded, it is fixed with ground nails. The fixing effect of the base 401 can be strengthened by fixing the first fixing seat 403, which improves the stability of the base 401 and makes it highly practical.

[0068] When controlling the opening and closing of the first fence 408, the motor 406 can be rotated. At this time, the opening and closing of the first fence 408 can be achieved through the meshing transmission of the second gear 407 and the first gear 405.

[0069] When a vehicle collides with the second fence 410, the spring 411 can provide cushioning, and at the same time, the two elastic blocks 412 can also provide cushioning. The double cushioning can improve the cushioning effect.

[0070] Example 3:

[0071] Based on Example 2, such as Figure 3 and Figure 8 As shown, it also includes: auxiliary parts 8, with two auxiliary parts 8 mounted on the base 401;

[0072] The auxiliary part 8 consists of a second fixed seat 801, a connecting shaft 802, a threaded tube 803 and a connecting seat 804, with the connecting seat 804 rotatably connected to the base 401;

[0073] The second fixing seat 801 is fixed to the wall. A connecting shaft 802 is welded to the second fixing seat 801. A threaded pipe 803 is rotatably connected to the connecting shaft 802. The threaded pipe 803 is threadedly connected to the connecting seat 804.

[0074] After the base 401 is installed, it can be fixed again by the auxiliary part 8. The connecting seat 804 is connected to the base 401, and then the second fixing seat 801 is fixed to the surrounding wall. Then, the threaded tube 803 is rotated to tighten the base 401, thus ensuring the strength of the base 401.

[0075] The specific usage and function of this embodiment are as follows:

[0076] During production, the team leader stands at 3 safety zones; during normal production, pneumatic fence A4 and ordinary fence 5 are closed, and pneumatic fence B6 is open.

[0077] The loader moves the excavated material from the roadheader to the loading area 2;

[0078] When loading is required, the engineering vehicle enters the pneumatic fence A4 on the working face. After the team leader sees the engineering vehicle through the monitoring video display terminal, he announces through the loudspeaker B706 that the loader should park in loading area 2. He then closes the pneumatic fence B6 by operating the controller 708, and then closes the pneumatic fence A4 by operating the controller 708. The engineering vehicle turns around in the shunting area and reverses into loading area 2 for loading.

[0079] During loading, the pneumatic barrier A4 is closed by the control unit 708, and other vehicles are not allowed to enter the work area during loading.

[0080] After loading is completed, the engineering vehicle drives to the video monitoring area of ​​the control ball C703 and sounds its horn to signal; after the team leader sees the engineering vehicle come to a complete stop through the monitoring video display terminal, he operates the controller 708 to open the pneumatic barrier A4, and the engineering vehicle drives away from the working face; after the team leader sees the engineering vehicle leave through the monitoring video display terminal, the controller 708 closes the pneumatic barrier A4, and then operates the controller 708 to open the pneumatic barrier B6 to allow the loader to enter the production area to dump the slag; this cycle is repeated until the tunneling operation is completed;

[0081] When personnel need to enter the working face for inspection, the personnel must first notify the shift leader via the speaker A705 controlled by the controller 708. After receiving the signal, the shift leader will notify the loader driver and the roadheader driver via the speaker B706. The loader driver will park the loader at loading area 2, stop the engine, and set up the wheel stopper and tripod. The roadheader driver will stop the roadheader and lock it. After that, the shift leader will open the pneumatic fence A4 via the controller 708. Only then can the personnel enter the working face.

[0082] When installing and using the pneumatic fence A4, the base 401 can be fixed first with ground nails. To ensure the stability of the base 401, the first fixing seat 403 needs to be pulled out and then fixed with ground nails. The fixing effect of the base 401 can be strengthened by the fixing of the first fixing seat 403, which improves the stability of the base 401 and makes it more practical.

[0083] At the same time, when controlling the opening and closing of the first fence 408, the motor 406 can be rotated. At this time, the opening and closing of the first fence 408 can be realized through the meshing transmission of the second gear 407 and the first gear 405.

[0084] When a vehicle collides with the second fence 410, the spring 411 can provide cushioning, and at the same time, the two elastic blocks 412 can also provide cushioning. The double cushioning can improve the cushioning effect.
