Description

Technical Field

[0001] The invention belongs to the technical field of supporting brackets, and in particular relates to a novel stable anchor supporting bracket. Background Art

[0002] Roadheaders are key and efficient equipment used in coal mine tunnel excavation. During the mining operation underground in a coal mine, after the roadheader completes coal cutting, temporary support and anchor operations must be implemented on the newly exposed roof in a timely manner, which is crucial to ensuring the construction safety of coal mine mining operations.

[0003] At present, temporary support of tunnels generally adopts staggered self-moving advance support devices, among which the walking support is the most common form. The walking support has a strong initial support force and can support the entire tunnel section. Through the mechanism of descending and moving in sequence, it can effectively support the tunnel roof of the working surface, providing a solid safety guarantee for construction personnel. However, the walking support also has some limitations. For example, its relatively large size not only occupies a lot of underground space, but also has a high manufacturing cost, which brings certain pressure to coal mining enterprises. In addition to the walking support, the stacking support is also widely used in temporary support of tunnels. The stacking support usually needs to be used in conjunction with a handling robot or a hanging rail lifting system to improve the handling efficiency of the stacking support. For the consideration of space utilization, the stacking support is more inclined to be used with the hanging rail lifting system. The hanging rail lifting system installs the hanging rail on the tunnel roof in advance. As the tunnel is continuously excavated, the hanging rail is used to move the stacking support at the rear to the newly excavated tunnel in front in sequence to support the newly exposed roof. Compared with the walking support, the stack support has significantly improved work efficiency, and is smaller in size and has lower manufacturing costs. However, this support method also faces a key problem. For newly excavated tunnels, there are no hanging rails installed on the newly exposed roof. Therefore, before hoisting the stack support, it is necessary to install the hanging rails on the working surface. Since the newly excavated tunnel is in an unsupported state for a period of time after the roof is exposed, stability is difficult to guarantee. For some construction workers who are not aware of safety, they may directly install the hanging rails without taking any safety measures. Once a safety accident such as roof collapse or block falling occurs, it will pose a serious threat to the lives of the construction workers.

[0004] Therefore, in response to the problems existing in the existing temporary support methods, we propose a new type of stable anchor support bracket to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 5The present invention provides a new type of stable anchor support bracket, including two groups of support devices arranged in parallel, the support device includes a plurality of stack-type brackets and a stepping assembly, the stack-type bracket includes a support base 1, a lifting seat 2, a first hydraulic telescopic rod 3 and a support top plate 4, the support base 1 is connected to the support top plate 4 through the first hydraulic telescopic rod 3, a second hydraulic telescopic rod 5 is provided below the support base 1, the lifting seat 2 is located below the support base 1 and is fixedly connected to the second hydraulic telescopic rod 5, the support base 1 is connected to a pulley 7 through a third hydraulic telescopic rod 6 on all four sides, and two adjacent support bases 1 are connected through a stepping assembly, and the stepping assembly includes a plurality of fourth hydraulic telescopic rods 8, and the two ends of the fourth hydraulic telescopic rod 8 are respectively hinged to the two adjacent support bases 1.

[0032] Two sets of support devices are arranged in parallel in the new type of stable anchor support bracket, which are symmetrically arranged on the left and right sides of the tunnel to provide stable temporary support. The specific working principle is as follows:

[0033] The height adjustment of each stack support depends on the telescopic action of the first hydraulic telescopic rod 3 configured between the support base 1 and the support top plate 4. In order to take into account both the support effect and cost-effectiveness, in this embodiment, four stack supports are configured in each support device. When not in use, all the hydraulic telescopic rods in the support device remain retracted, so that the entire support device has a compact structure and is easy to store and transport. In the early stage of mining operations underground in a coal mine, due to the limited length of the tunnel, it is difficult for the support device to be fully deployed. At this time, only the first hydraulic telescopic rod 3 is extended to make the support top plate 4 close to the tunnel roof, achieving preliminary temporary support, and bolting operations are performed after the temporary support is completed. As the tunneling machine continues to advance in cutting the coal body, the working surface gradually extends, and the support device begins to gradually unfold: first, the first stack support located in the front of the two groups of support devices, by retracting the first hydraulic telescopic rod 3, lowers the support top plate 4 and no longer supports the tunnel roof. Subsequently, the second hydraulic telescopic rod 5 is extended to lift the support base 1. Next, the third hydraulic telescopic rod 6 is extended to make the pulley 7 contact the ground, in preparation for the next moving step. After that, the second hydraulic telescopic rod 5 is retracted, and the fourth hydraulic telescopic rod 8 is extended to push the first stacking support forward until the fourth hydraulic telescopic rod 8 is fully extended. Finally, the third hydraulic telescopic rod 6 is retracted, the pulley 7 is raised, the lifting seat 2 is in contact with the ground, and the first hydraulic telescopic rod 3 is extended at the same time, so that the supporting top plate 4 supports the tunnel top plate again. At this time, the maximum spacing is reached between the first stacking support and the second stacking support, while the minimum spacing is still maintained between the second stacking support and the third stacking support, and between the third stacking support and the fourth stacking support. Therefore, the entire support device needs to be fully extended to achieve the maximum spacing between each stacking support and the maximum support length. It is also necessary to move the second stacking support and the first stacking support forward in turn according to the above-mentioned moving method as the working surface continues to advance, so that the maximum spacing is reached between the second stacking support and the third stacking support. Then, move the third stack support, the second stack support and the first stack support forward in sequence, so that the third stack support and the fourth stack support also reach the maximum spacing. At this point, each stack support reaches the maximum spacing, and the entire support device is fully deployed. After that, as the working face advances, the moving mechanism of the support device becomes a lowering and moving mechanism in sequence from back to front, effectively supporting the roadway roof of the working face and providing a solid safety guarantee for the construction personnel. It is worth mentioning that after each working face advances and completes temporary support, bolt operations are required on the newly exposed roof to reinforce the roadway roof and ensure the safety of coal mining operations.Compared with the traditional temporary support method of the tunnel, this new type of stable anchor support bracket combines the advantages of the walking bracket and the stacking bracket, improves the comprehensive excavation efficiency, and effectively protects the life safety of the construction personnel. Its small size avoids occupying more underground space like the walking bracket, while reducing the equipment cost and alleviating the economic pressure brought by the equipment cost to the coal mining enterprises. In addition, this new type of stable anchor support bracket does not need to be transported by a handling robot or a hanging rail hoisting system to transport the stacking bracket, thereby avoiding the safety hazards in the hanging rail installation operation, and providing an efficient and safe support solution for coal mining operations.

[0034] In a specific embodiment, see Figure 1 and Figure 5 There are two first hydraulic telescopic rods 3, and the top ends of the two first hydraulic telescopic rods 3 are each provided with a through groove 9, in which a first connecting rod 10 is provided, and two second connecting rods 11 are rotatably provided inside the support top plate 4, the two second connecting rods 11 are arranged in parallel, and the first connecting rod 10 vertically penetrates the middle part of the second connecting rod 11 and is rotatably connected to the second connecting rod 11.

[0035] Through the two first hydraulic telescopic rods 3, a more stable supporting force can be provided for the supporting top plate 4, thereby enhancing the supporting effect of the supporting structure. In addition, the first hydraulic telescopic rod 3 and the supporting top plate 4 are connected by the first connecting rod 10 and the second connecting rod 11, realizing the rotation function of the supporting top plate 4 in four directions of front, back, left and right. Specifically, the second connecting rod 11 and the supporting top plate 4 are rotatably connected. By accurately controlling the telescopic length of the two first hydraulic telescopic rods 3, the two first hydraulic telescopic rods 3 are made to present different heights, so that the tilt adjustment of the supporting top plate 4 in the front and back directions can be realized. When the supporting top plate 4 is uneven in the left and right directions, the second connecting rod 11 will rotate around the first connecting rod 10 during the process of the first hydraulic telescopic rod 3 raising the supporting top plate 4, so that the supporting top plate 4 can be tilted and adjusted in the left and right directions. This mechanism enables the supporting top plate 4 to effectively fit the contour of the roadway roof, ensure the supporting effect, and thus better adapt to various complex and changeable roadway conditions, providing a safer and more reliable support guarantee for coal mining operations.

[0036] In a specific embodiment, see Figure 1 , Figure 2 and Figure 3 The support base 1 is provided with an auxiliary fixing assembly, and the auxiliary fixing assembly includes a reinforcing bracket 12 and a fixed support rod 13. The reinforcing bracket 12 is fixedly sleeved on the first hydraulic telescopic rod 3, and the two ends of the fixed support rod 13 are fixedly connected to the fixing frame and the support base 1 respectively.

[0037] The auxiliary fixing assembly not only effectively disperses the load of the first hydraulic telescopic rod 3 during the pressure-bearing process by strengthening the synergistic effect of the bracket 12 and the fixed support rod 13, but also improves its ability to resist bending deformation, thereby effectively enhancing the overall bearing capacity of the support device, so that it can maintain a more lasting and stable support effect when facing the pressure of the tunnel roof, which not only helps to extend the service life of the support device, but also reduces the risk of safety accidents that may be caused by support failure.

[0038] In a specific embodiment, see Figure 1 , and also includes a fifth hydraulic telescopic rod 14, both ends of which are respectively hinged to the reinforcing brackets 12 on the two adjacent stack-type brackets.

[0039] If the pulling operation is only carried out by relying on the fourth hydraulic telescopic rod 8 at the bottom, the stacking support may deflect due to the low position of the force point, thereby increasing the risk of tipping over, which poses a potential threat to the safety of the support operation. In order to effectively avoid this safety hazard, by adding a fifth hydraulic telescopic rod 14 and hingedly connecting it with the reinforcing brackets 12 on the two adjacent stacking supports, when the stacking support moves, the fifth hydraulic telescopic rod 14 at the top can cooperate with the fourth hydraulic telescopic rod 8 at the bottom to provide a stable and balanced support force for the movement of the stacking support, which not only significantly improves the stability of the movement of the stacking support, but also greatly reduces the safety risk of the stacking support tipping over due to uneven force.

[0040] In a specific embodiment, see Figure 2 The fixed end of the first hydraulic telescopic rod 3 of the front stack-type bracket is rotatably sleeved with a rotating ring 15, and a sixth hydraulic telescopic rod 16 is fixedly connected to the rotating ring 15. The movable end of the sixth hydraulic telescopic rod 16 is provided with a fixing ring 17, and an anchor drill 18 is arranged in the fixing ring 17.

[0041] Since the anchor drill 18 has a large weight, if the traditional anchor operation method is used, after the tunneling machine completes the excavation, the drilling support workers need to carry the anchor drill 18, anchors and other support materials from the rear of the tunneling machine to the working surface for support and anchoring. This method is not only labor-intensive and time-consuming, but also seriously restricts the improvement of production efficiency. In order to solve these problems, the new stable anchor support bracket is designed with a combination of a rotating ring 15, a sixth hydraulic telescopic rod 16 and a fixed ring 17 to install the anchor drill 18 on the fixed end of the first hydraulic telescopic rod 3 of the frontmost stack bracket. In actual use, the anchor drill 18 can achieve rapid and flexible adjustment of the working position with the help of the rotation of the rotating ring 15 and the extension of the sixth hydraulic telescopic rod 16, effectively avoiding the cumbersome process of manually carrying the anchor drill 18, reducing the labor intensity of the anchor operation, shortening the working time, and effectively improving the production efficiency.

[0042] In a specific embodiment, see Figure 2 The rotating ring 15 is provided with a seventh hydraulic telescopic rod 19 on the opposite side of the sixth hydraulic telescopic rod 16 , and the movable end of the seventh hydraulic telescopic rod 19 and the end of the fixed ring 17 are both provided with an anti-skid plate 20 .

[0043] In the design of the new type of stable anchor support bracket, the sixth hydraulic telescopic rod 16, the seventh hydraulic telescopic rod 19, and the anti-slip plate 20 located at the movable end of the seventh hydraulic telescopic rod 19 and the end of the fixed ring 17 together constitute a deviation adjustment mechanism. When the new type of stable anchor support bracket deviates during operation, the position can be adjusted quickly and effectively to ensure the stability and normal operation of the new type of stable anchor support bracket. Specifically, the operator can control the seventh hydraulic telescopic rod 19 in the two groups of support devices to extend the anti-slip plate 20 at the movable end and tightly abut against the side of the lane. At the same time, the anti-slip plate 20 at the end of the fixed ring 17 also abuts against each other. By accurately controlling the telescopic coordination of the sixth hydraulic telescopic rod 16 and the seventh hydraulic telescopic rod 19 in the support devices on both sides, the operator can flexibly adjust the position of the front stack support to move it outward or inward, thereby completing the position adjustment of the support device.

[0044] In a specific embodiment, see Figure 4 A plurality of cavities 21 are provided below the support base 1 , and a second hydraulic telescopic rod 5 is provided in each of the cavities 21 .

[0045] The second hydraulic telescopic rod 5 is arranged in the cavity 21 below the support base 1. After the second hydraulic telescopic rod 5 is fully retracted, it can be stored in the cavity 21, so that the support base 1 and the lifting seat 2 can achieve stable contact when the second hydraulic telescopic rod 5 is retracted, thereby forming a stable and reliable "base" together, effectively enhancing the overall support stability of the stacking bracket. It is worth mentioning that the second hydraulic telescopic rod 5 only bears the load when in use, and no longer bears the load in the retracted state, which effectively increases the service life of the second hydraulic telescopic rod 5 and reduces the cost of maintenance and replacement.

[0046] In a specific embodiment, see Figure 1 and Figure 3 Auxiliary support components are provided on the left and right sides of the support base 1, and the auxiliary support components include an auxiliary support base plate 22 and two eighth hydraulic telescopic rods 23. The two ends of the eighth hydraulic telescopic rod 23 are respectively hinged to the auxiliary support base plate 22 and the support base 1.

[0047] The auxiliary support assembly cooperates with the support base plate and the eighth hydraulic telescopic rod 23. During operation, the eighth hydraulic telescopic rod 23 can share part of the load borne by the support base 1 and transfer this part of the load to the ground through the support base plate, thereby achieving load dispersion, reducing the load-bearing burden of the support base 1, and improving the supporting capacity of the stack-type bracket, thereby effectively enhancing the overall performance of the support bracket.

[0048] In a specific embodiment, see Figure 1 and Figure 3 The support base 1 is provided with guard plates 24 on the outer sides of the third hydraulic telescopic rod 6 at the front and rear sides, and the end of the fourth hydraulic telescopic rod 8 is hinged to the guard plate 24.

[0049] The design of the guard plate 24 covers the third hydraulic telescopic rod 6 and the pulley 7 areas on the front and rear sides of the support base 1, which can effectively reduce the risk of direct impact of debris, rocks and other debris that may be generated during operation on the third hydraulic telescopic rod 6 and the pulley 7, thereby extending the service life of the third hydraulic telescopic rod 6 and the pulley 7, reducing downtime and maintenance costs caused by accidental damage, and effectively ensuring the mobility of the stacking bracket.

[0050] In a specific implementation, the supporting top plates 4 are each provided with an illumination lamp.

[0051] By arranging lighting lamps on the supporting top plate 4, the lighting conditions at the work site are improved, so that the operator can observe the work environment more clearly, ensure the safety and accuracy of the work, and help improve the work efficiency and quality.
