[0030] 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.

[0031] See also Figure 1-6 , the utility model provides a technical solution:

[0032] Embodiment 1:

[0033] A novel coal mine plugging device comprises a transport vehicle 1 and a plugging support assembly 6, a support plate 3 is rotatably arranged on the chassis of the transport vehicle 1, a first hydraulic oil cylinder 4 is rotatably arranged between the transport vehicle 1 and the support plate 3, and the support plate 3 can achieve angle change on the transport vehicle 1 through the extension and contraction of the first hydraulic oil cylinder 4, a second hydraulic oil cylinder 5 is fixedly arranged on the support plate 3, and a mounting plate 2 is fixedly arranged on the movable end of the second hydraulic oil cylinder 5;

[0034] The transport vehicle 1 in this embodiment is a crawler transport vehicle 1. The transport vehicle 1 is the basic structure of the new coal mine plugging device, which carries the mobile function of the entire device. The operator can move it by remote control. The transport vehicle 1 is made of sturdy and durable materials to adapt to the harsh environment of underground mines. The chassis is designed with a low center of gravity to improve driving stability, and is equipped with a high-performance drive system and suspension system to ensure smooth driving even in uneven mine tunnels. The transport vehicle 1 is also equipped with lighting equipment to facilitate operations in dark mines. Ensure that the plugging device can adapt to tunnels of different heights.

[0035] The blocking bracket assembly 6 includes a movable baffle 601, a fixed baffle 602 and a load-bearing oil cylinder 6023. The movable baffle 601 is slidably arranged on the fixed baffle 602. The load-bearing oil cylinder 6023 is arranged between the movable baffle 601 and the fixed baffle 602. Through the extension and retraction of the load-bearing oil cylinder 6023, the movable baffle 601 can slide between the fixed baffle 602.

[0036] The plugging support assembly 6 is the core part of the plugging device, and is composed of a movable baffle 601, a fixed baffle 602, and a load-bearing oil cylinder 6023. The movable baffle 601 can slide on the fixed baffle 602 as needed to form an adjustable plugging surface to adapt to lane openings of different widths. The fixed baffle 602 provides a stable fulcrum, and the mounting hole 6024 opened thereon matches the mounting plate 2, so that the plugging support assembly 6 is matched with the support plate 3 on the transport vehicle 1. The load-bearing oil cylinder 6023 serves as a power source, and controls the sliding of the movable baffle 601 through its extension and contraction to achieve rapid and accurate plugging.

[0037] The fixed baffle plate 602 is provided with a mounting hole 6024 that matches the mounting plate 2 , and the mounting plate 2 is detachably disposed in the mounting hole 6024 .

[0038] The operator installs the blocking bracket assembly 6 on the transport vehicle 1 through the mounting plate 2 and the mounting hole 6024. In the transport state, the blocking bracket assembly 6 is in a horizontal or inclined state to facilitate passing through lanes with different heights. When the transport vehicle 1 carrying the blocking bracket assembly 6 arrives at the blocking position, the operator opens the third hydraulic cylinder 7, and the third hydraulic cylinder 7 extends to support the front end of the transport vehicle 1 to prevent the transport vehicle 1 from overturning during operation;

[0039] After the third hydraulic cylinder 7 is in place, the operator starts the first hydraulic cylinder 4 to make the blocking bracket assembly 6 vertical, and then starts the load-bearing cylinder 6023. The load-bearing cylinder 6023 extends to drive the movable baffle 601 to extend to block the tunnel. After the movable baffle 601 is in place, the operator starts the second hydraulic cylinder 5, and the second hydraulic cylinder 5 contracts to disengage the mounting plate 2 from the mounting hole 6024, and withdraw the transport vehicle 1.

[0040] The design of the T-slot 6021 and the slider 6022 further enhances the sliding accuracy and stability of the movable baffle 601 on the fixed baffle 602. The T-slot 6021 is on the fixed baffle 602, and the slider 6022 is fixed on the movable baffle 601. The cooperation of the two makes the movable baffle 601 move smoothly without derailment, ensuring the reliability of the blocking process.

[0041] The rectangular design of the mounting plate 2 and the mounting hole 6024 provides a good mechanical fit, ensuring a secure connection between the plugging support assembly 6 and the transport vehicle 1. This design allows for quick installation and removal, facilitating maintenance and replacement of the plugging device.

[0042] Embodiment 2:

[0043] In this embodiment, in order to ensure the stability of the device in use, a third hydraulic cylinder 7 and other devices are added in this embodiment to support the body of the transport vehicle 1 during work;

[0044] The combination of the third hydraulic cylinder 7 and the ball head 701 supporting foot 702 increases the stability of the device. The extension of the third hydraulic cylinder 7 can adjust the height of the supporting foot 702, and the design of the ball head 701 allows the supporting foot 702 to rotate within a certain range to adapt to the unevenness of the ground. The anti-skid pad 703 on the supporting foot 702 increases the friction with the ground to prevent the device from shifting during the blocking process.

[0045] The support baffle 8 at the bottom of the fixed baffle 602 and the vertically arranged reinforcing ribs 9 together enhance the structural strength of the fixed baffle 602 to prevent deformation caused by load bearing or external pressure. The support baffle 8 provides additional support, while the reinforcing ribs 9 disperse the load to ensure the durability of the device under complex geological conditions.

[0046] The design of the connection ear 10 and the connection hole 1001 is to facilitate the fixing of the plugging device to other equipment or the tunnel wall. The connection ear 10 is made of high-strength material, and the connection hole 1001 can accommodate bolts of various sizes to meet different fixing requirements.

[0047] The sealing strips 11 surround the fixed baffle 602 and the movable baffle 601 and are the key to ensuring long-term effective sealing performance. These sealing strips 11 are made of wear-resistant and corrosion-resistant materials and can maintain a good sealing effect in the wet and dusty environment of the mine to prevent coal dust, water or other substances from leaking from the sealing gap.

[0048] Through the coordinated work of the above components, the new coal mine plugging device can effectively cope with the plugging task under complex geological conditions. The flexible adjustment capability of the first hydraulic cylinder 4 and the third hydraulic cylinder 7 enables the device to adapt to different tunnel environments; the precise matching of the T-slot 6021 and the slider 6022 ensures the stable sliding of the movable baffle 601; and the sealing strip 11 ensures the tightness of the plugging. In addition, the enhanced structural design and anti-skid measures ensure that the device can still maintain its sealing performance after long-term use, thereby meeting the requirements of safe operation in coal mines.

[0049] Working principle: During the use of the utility model, through remote control operation, the crawler transport vehicle 1 carries the blocking bracket assembly 6 and moves in the mine. With its sturdy and durable structure and low center of gravity design, it can travel smoothly on uneven mine roads and is equipped with lighting equipment to adapt to dark environments.

[0050] The operator installs the blocking bracket assembly 6 on the support plate 3 of the transport vehicle 1 through the mounting plate 2 and the mounting hole 6024. During transportation, the blocking bracket assembly 6 remains in a horizontal or inclined state, which is convenient for passing through lanes of different heights.

[0051] When the transport vehicle 1 carrying the blocking bracket assembly 6 reaches the blocking position, the third hydraulic cylinder 7 extends to support the front end of the transport vehicle 1 to prevent it from overturning during operation.

[0052] The operator starts the first hydraulic cylinder 4 to transform the blocking support assembly 6 from a horizontal or inclined state to a vertical state, so as to prepare for the blocking operation.

[0053] The load-bearing oil cylinder 6023 is started to control the sliding of the movable baffle 601 on the fixed baffle 602 through its extension and contraction. The movable baffle 601 adjusts its position according to the height of the lane to achieve rapid and accurate blocking of the lane.

[0054] After the movable baffle 601 is in place, the operator starts the second hydraulic cylinder 5 to disengage the mounting plate 2 from the mounting hole 6024, and then withdraws the transport vehicle 1 to complete the blocking operation.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
