Description

Technical Field

[0001] This utility model relates to the field of safety equipment technology, specifically to an anti-slip device for storage compartments. Background Technology

[0002] The 2.5-meter diameter full-face hard rock tunnel boring machine at Zhangji Mine achieved remarkable results: a single-shift advance of 14.7 meters, a round-shift advance of 30 meters, and a total monthly advance of 516 meters. This not only increased the single-shift advance and production efficiency of rock tunnel excavation by more than five times but also generated significant economic benefits. However, this high efficiency necessitates the output of a large volume of material from the tunnel boring machine. The output primarily consists of small-particle, sticky gangue that requires water cooling, resulting in a high-moisture, low-material sticky gangue. This high-moisture, low-material sticky gangue is collectively referred to as "water coal." This water coal enters the gangue bin and is then discharged via a coal feeder. Existing coal feeders are prone to bin overflow when encountering large water coal flows, which can damage equipment, bury workers, and cause safety accidents.

[0003] Chinese utility model patent document CN204489946U discloses a coal feeder anti-coal hopper device, including a device body connected to the coal feeder. The device body includes a cylinder connected to the side wall of the coal bin of the coal feeder via a piston rod. A gate is connected to the side wall of the cylinder, and a gate control device is also connected to the cylinder. Using this utility model, the opening and closing of the gate is controlled by the extension and retraction of the cylinder. When coal hopper leakage occurs, the opening and closing degree of the gate can be adjusted according to the amount of coal leakage, thereby controlling the water-coal flow and preventing accidents that could harm personal safety or damage equipment. This ensures safety, improves work efficiency, and saves maintenance costs. The gate control device connected to the cylinder can quickly and promptly close the gate when coal hopper leakage occurs, further enhancing safety and improving work efficiency.

[0004] However, if the above-mentioned anti-slip device for the coal feeder encounters a large flow of water and coal, the pressure of the water and coal will force the gate open, making it uncontrollable; furthermore, the anti-slip device only targets the outlet of the coal feeder and cannot target the entire coal feeder or other equipment, thus failing to provide comprehensive and effective anti-slip measures. Utility Model Content

[0005] The technical problem to be solved by this utility model is how to ensure that the gate is stable and not blown open when the water and coal flow is large, and how to effectively and comprehensively prevent crossflow.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] This utility model provides an anti-slip device, which is connected to a coal feeder and includes a baffle, a slide rail, and a sealing baffle. The slide rail is fixed on both sides of the coal feeder outlet, the baffle can move in the slide rail, the baffle is connected to a telescopic mechanism, and the sealing baffle is fixed on the upper part of the coal feeder.

[0008] Beneficial effects: This utility model, through the cooperation of a baffle, a slide rail, and a telescopic mechanism, ensures that the baffle moves along the slide rail, preventing it from affecting the normal operation of the coal feeder and simultaneously preventing cross-contamination. The slide rail ensures the flexible movement of the baffle and can withstand the impact force of cross-contamination, ensuring stable baffle operation even with large water and coal flow rates, preventing it from being blown open. The height of the baffle is adjusted via the telescopic mechanism, both preventing cross-contamination and meeting normal equipment operation requirements. To completely prevent cross-contamination, a sealing baffle is fixed to the upper part of the coal feeder. The sealing baffle is easy to install and remove, preventing cross-contamination at the upper part of the coal feeder, which would cause the coal feeder to malfunction and affect coal delivery.

[0009] Preferably, the telescopic mechanism is fixed on the top aisle, and the telescopic end of the telescopic mechanism is connected to the baffle.

[0010] Preferably, the telescopic mechanism is a cylinder or a hand chain hoist.

[0011] Preferably, the sealing baffle is provided with an observation hole, which is located on the side of the sealing baffle.

[0012] Beneficial effects: This utility model has an observation hole in the sealing baffle, which makes it easy to observe the internal condition of the coal feeder.

[0013] Preferably, the baffle is made of 10mm thick wear-resistant steel plate, with a length of 1250mm and a height of 1000mm.

[0014] Preferably, the sealing baffle is made of 10mm thick wear-resistant steel plate, with a length of 1400mm and a width of 400mm.

[0015] Preferably, the slide rail is made of 7# angle steel and has a length of 600mm.

[0016] Preferably, the cylinder is connected to the controller.

[0017] Preferably, the anti-channeling device further includes a coal chute reinforcement device, which consists of side plates installed on both sides of the coal chute and fixed with steel plates.

[0018] Beneficial effects: This utility model is designed to prevent a small amount of sticky gangue from falling onto the conveyor belt and causing gangue to accumulate below the conveyor belt. It reinforces the coal chute to prevent the sticky gangue from spilling out. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] according to Figure 1 As shown, this embodiment provides an anti-channeling device, which is connected to the coal feeder 7 and the coal chute 5. It includes a baffle 1, a slide rail 2, a cylinder 3, and a controller 6. The cylinder 3 is fixed in the top roadway, and its telescopic end is connected to the baffle 1. The slide rail 2 is fixed on both sides of the coal feeder 7 outlet by bolts. The baffle 1 moves up and down in the slide rail 2. At the coal feeder 7 outlet, the baffle 1 is raised and lowered by the cylinder 3, controlling the opening and closing of the outlet and thus controlling the output of the coal feeder 7 to prevent channeling. The cylinder 3 is connected to the controller 6, which controls the extension and retraction of the cylinder 3. The height of the baffle 1 is adjusted using the cylinder 3. Adjusting the height of the baffle 1 according to the output situation can both prevent channeling and ensure the normal operation of the coal feeder 7.

[0023] In this embodiment, through the cooperation of baffle 1, slide 2 and cylinder 3, baffle 1 moves up and down on slide 2 to ensure that baffle 1 does not affect the normal operation of coal feeder 7 during use, and at the same time plays the role of preventing cross-contamination. Slide 2 can ensure the flexible movement of baffle 1, and can withstand the impact force of baffle 1 when cross-contamination occurs, ensuring that baffle 1 is stable in preventing cross-contamination when the water and coal flow is large, and is not blown open. The height of baffle 1 is adjusted by cylinder 3, which can both prevent cross-contamination and meet the normal operation of coal feeder 7.

[0024] The dimensions of the baffle 1 are set according to the actual amount of coal feeder 7 moving into the bin. In this embodiment, it is used in the No. 2 auxiliary shaft of Zhangji Coal Mine of Huainan Mining Group to ensure that the baffle 1 does not affect the normal operation of the coal feeder 7 when in use, and at the same time can play the role of preventing coal feeder 7 from moving into the bin. Therefore, the baffle 1 is made of 10mm thick wear-resistant steel plate, with a length of 1250mm and a height of 1000mm.

[0025] The slide 2 is designed according to the thickness, angle and height of the baffle 1. The slide 2 can ensure that the baffle 1 can move up and down flexibly, and also ensure that the strength can withstand the impact force of the baffle 1 when the compartment moves. Therefore, the slide 2 uses 7# angle steel and has a length of 600mm.

[0026] The anti-channeling device also includes a sealing baffle 4, which is fixed to the upper part of the coal feeder 7. To completely prevent channeling, the upper part of the coal feeder 7 is also sealed. When sealing, care must be taken to ensure that the material used can withstand a certain amount of impact while facilitating installation and disassembly. The function of the sealing baffle 4 is to prevent channeling from the upper part of the coal feeder 7, which would cause the coal feeder 7 to malfunction and affect its output. Therefore, the sealing baffle 4 is made of 10mm thick wear-resistant steel plate, 1400mm long and 400mm wide, to seal the upper part of the coal feeder, while also providing an observation hole (not shown in the figure) for easy inspection of the internal condition of the coal feeder 7.

[0027] To prevent a small amount of coal and water from falling onto the conveyor belt and causing gangue to accumulate below it, the coal chute 5 also needs to be reinforced to prevent coal and water from spilling out. Therefore, the anti-channeling device also includes a reinforcement device for the coal chute 5, which consists of side plates installed on both sides of the coal chute 5 and fixed with steel plates.

[0028] The working principle of the anti-channel cross-containment device in this embodiment is as follows:

[0029] The operator observes the coal feeder 7's output. If the water-coal flow rate is high, the operator controls the cylinder 3 to extend through the controller 4 and uses the baffle 1 to reduce the water-coal output speed. If the output is normal, the operator controls the cylinder 3 to retract and uses the baffle 1 to increase the water-coal output speed.

[0030] The anti-coal spillage device in this embodiment solves the problem of coal spillage from tunnel boring machines (TBMs) due to the large volume and small particle size of the coal. Previously, spillage occurred on average once every three days, with each spillage involving 6-8 tons. This not only posed a serious safety risk but also required at least two people working a shift to completely clean up the spillage. This anti-coal spillage device can save 70,000 yuan annually in labor costs alone, while also reducing the impact on production time and damage to the coal feeder 7. It significantly improves the safety of production and operations, increases production efficiency, and ensures the smooth operation of the TBM production line.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
