Description

Technical Field

[0001] This utility model relates to the field of tunneling support technology, specifically a coal mine tunneling support device. Background Technology

[0002] Coal mine tunneling support is a core measure to ensure the safety of underground operations and the continuity of production. Its function is to effectively resist the deformation, cracking and collapse of the surrounding rock during tunneling by scientifically arranging support structures such as anchor bolts, anchor cables, steel frames and shotcrete, and prevent accidents such as roof falls and spalling. At the same time, the support system can reasonably disperse and transfer ground stress, maintain the stability of the surrounding rock in the roadway, and provide a safe and reliable space for personnel and equipment passage and subsequent mining operations, thereby ensuring the efficient advancement and long-term stable operation of coal mine production.

[0003] Most coal mine tunneling support equipment uses a single support method, making it difficult to form a stable support system from multiple angles. This leads to stress imbalance when dealing with ground stress in different directions, and the equipment cannot effectively disperse and resist pressure from the top, increasing the risk of support structure instability. In addition, traditional support operations generate a lot of dust during drilling, blasting, and anchoring. Coupled with the lack of effective dust suppression measures in some equipment, the dust concentration at the work site exceeds the standard. This not only seriously pollutes the underground working environment, reduces visibility, and affects construction efficiency, but also causes long-term health damage to the respiratory system and eyes of workers, becoming an important hidden danger for the prevention and control of occupational diseases in coal mines.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 As shown, a coal mine tunneling support device includes a coal mine tunneling device body 1, a water pump 2 fixed on the surface of the coal mine tunneling device body 1, a water spraying mechanism 3 provided on the surface of the water pump 2, a fixing block 4 provided on the surface of the water spraying mechanism 3, a support mechanism 5 provided on the surface of the coal mine tunneling device body 1, a support rod 6 rotatably provided on the surface of the coal mine tunneling device body 1, and an embedding groove 7 opened in the inner cavity of the support rod 6.

[0016] The coal mine tunneling device body 1 includes a first hydraulic rod 111 disposed on its own surface, and a second hydraulic rod 112 disposed on the surface of the coal mine tunneling device body 1. The second hydraulic rod 112 is located 10 cm in front of the rotation axis of the support plane, and the thrust of the second hydraulic rod 112 is used to support the support plane to a horizontal position.

[0017] The first hydraulic rod 111 is disposed on the surface of the coal mine tunneling device body 1 to provide support for the equipment and provide linkage capability for some of its internal parts. It also includes a support panel that contacts the rock and provides large-area support through its wide area.

[0018] The second hydraulic rod 112 is installed on the surface of the coal mine tunneling device body 1, and is also used to provide support for the internal parts and provide linkage capability for the internal parts.

[0019] The water pump 2 is fixed to the surface of the coal mine tunneling device body 1, providing water source for the water spraying mechanism 3 and providing the power required for spraying.

[0020] The water spraying mechanism 3 is installed on the surface of the coal mine tunneling device body 1. When the machine is fully operational, it will generate a large amount of dust. In a confined environment, the spread of dust may reduce internal visibility, which may cause danger and even harm to the workers.

[0021] The water spraying mechanism 3 includes a folded water pipe 31 connected to the output end of the water pump 2. The other end of the folded water pipe 31 is connected to a flat pressure water pipe 32. Both ends of the flat pressure water pipe 32 are connected to connecting water pipes 33. The other end of the connecting water pipe 33 is connected to a water tank 34. Several nozzles 35 are connected to the surface of the water tank 34.

[0022] The folded water pipe 31 is connected to the output end of the water pump 2. It is a water pipe whose length and shape can be controlled by folding. Through its variable characteristics and the adjustment of the support mechanism 5, it can change in real time without causing damage, and transmit the liquid output by the water pump 2 to the inside of the flat pressure water pipe 32.

[0023] The flat-pressure water pipe 32 is fixed to the inner wall of the fixing block 4. The water is transported in a split manner through the straight water pipe, so that the water pipes 33 on both sides can receive water resources.

[0024] The connecting water pipe 33 is a rubber water pipe with uniform and aging-resistant properties. Due to its softness, it can move and adjust the internal parts without affecting the adjustment when the support mechanism 5 is adjusted.

[0025] The water tank 34 is connected to one end of the water pipe 33 and is used to store and distribute the liquid, so as to deliver the incoming liquid into all the nozzles 35, thereby ensuring that the spraying is uniform and that the dust suppression capability is guaranteed.

[0026] The nozzles 35 are arranged in an array connected to the surface of the water tank 34, with a total of six nozzles. By spraying liquid above the drill bit, the dust generated is caused to settle, thereby reducing the degree of dust stirring and protecting the working environment and the workers.

[0027] The nozzle 35 is a venturi tube with an atomizing filter fixed on its surface. It can atomize the incoming liquid, thereby improving its ability to adsorb dust and ensuring that the required dust suppression capacity is provided with a certain number of nozzles 35.

[0028] The fixing block 4 is fixed to the surface of the support rod 6, which serves to fix the flat water pipe 32 and ensure that it will not fall off due to vibration when the support mechanism 5 is folded.

[0029] The support mechanism 5 is set on the surface of the coal mine tunneling device body 1. Without affecting its folding ability, it provides support to one end of the support panel at the upper end, ensuring the balance of its support force, thereby preventing the unsupported end from overturning or deforming due to excessive force.

[0030] The support mechanism 5 includes a first rotating shaft 51 fixed to the inner wall of the support rod 6, a hydraulic groove 52 rotating on the surface of the first rotating shaft 51, a hydraulic push rod 53 sliding on the inner wall of the hydraulic groove 52, a second rotating shaft 54 ​​rotating on the inner wall of the hydraulic push rod 53, and a sliding groove 55 sliding on the surface of the second rotating shaft 54.

[0031] The first rotating shaft 51 is fixed to the inner wall of the support rod 6, providing support for the rotation of the hydraulic tank 52.

[0032] The hydraulic groove 52 rotates on the surface of the first rotating shaft 51, providing support for the sliding of the hydraulic push rod 53, providing support for the advancement of the hydraulic push rod 53, and cooperating with the hydraulic push rod 53 to provide support for the support panel.

[0033] The hydraulic push rod 53 slides on the inner wall of the hydraulic groove 52 to bear the force brought by the support panel, and the angle of the support panel can be controlled by adjusting its length.

[0034] The second rotating shaft 54 ​​slides on the inner wall of the support panel, and its position is adjusted by sliding each time the equipment is opened and closed. The sliding adjustment is achieved through the cooperation of the first hydraulic rod 111 and the second hydraulic rod 112.

[0035] The sliding groove 55 is formed on the inner wall of the coal mine tunneling device body 1 to limit the sliding trajectory of the second rotating shaft 54 ​​and guide it to prevent it from suddenly slipping and causing equipment damage.

[0036] The support rod 6 rotates on the surface of the coal mine tunneling device body 1 to provide support for the upper support panel and to provide storage space for the support mechanism 5.

[0037] The support rod 6 is made of titanium alloy and has high corrosion resistance, ensuring that it can support the upper support block without being corroded or aged due to excessive humidity.

[0038] The embedded groove 7 is opened in the inner cavity of the support rod 6 to facilitate the folding of the support mechanism 5 and to store some parts of the support mechanism 5, thereby reducing its occupied area.

[0039] Working principle: When it is necessary to excavate in the coal mine, the support rod 6 gradually unfolds under the push of the first hydraulic rod 111 until it stops at 45°. At this time, the second hydraulic rod 112 pushes, acting on the non-axis rotation vertical line, pushing the support panel to a horizontal angle of 45° and stopping. At this time, the hydraulic groove 52 is inclined upward. Then, the PLC controls the hydraulic groove 52 to start pushing the hydraulic push rod 53 to advance. Under the action of the angle, the second rotating shaft 54 ​​continuously slides on the surface of the sliding groove 55, eventually reaching the highest point. At this time, the first hydraulic rod 111 starts again to push the support rod 6 to the next position. In a vertical position, the second hydraulic rod 112 is also continuously pushed until the support panel is pushed to a horizontal position, thus completing the unfolding. Under the support of the support mechanism 5, a more balanced support force can be provided for the support panel. The water pump 2 is turned on, and under the pressure of the water pump 2, the liquid enters the flat pressure water pipe 32 through the folded water pipe 31. Under the distribution of the flat pressure water pipe 32, the liquid enters the corresponding water tank 34 and is squeezed into a mist by the nozzle 35, thereby ensuring its dust settling ability. While ensuring the equipment support strength, it also reduces the degree of dust rising.
