DETAILED DESCRIPTION
[0025] To make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.
[0026] As Figures 1-5As shown, a thin coal seam mining with multi-functional support, including base 1, the left and right sides of base 1 are both fixedly connected with support plate one 2, the upper part of the opposite side of two support plate one 2 is commonly fixedly connected with support plate two 3, the upper surface of support plate one 2 and support plate two 3 is both fixedly connected with support seat 4, the lower part of support plate two 3 is movably connected with support mechanism 5;
[0027] Support mechanism 5 includes support frame 51, the upper surface of support frame 51 is fixedly connected in the middle of support plate two 3 lower surface, the front side of support frame 51 is fixedly connected with motor 52, the output end of motor 52 is fixedly connected with threaded rod 53, the outer periphery of threaded rod 53 is threadedly connected with two sliders one 54 distributed in front and back, the left and right sides of slider one 54 are both rotatably connected with connecting rod 57, the middle of support plate two 3 lower part is slidably connected with two sliders two 55 distributed in left and right, the left and right sides of sliders two 55 are respectively rotatably connected with connecting rod 57 far away from slider one 54, the opposite side of two sliders two 55 is both fixedly connected with support plate three 56.
[0028] It needs to be explained that base 1 is the support foundation of the whole support, which ensures the stability of the support in the process of mining. Support plate one 2 connects base 1 and support plate two 3, providing additional support force to ensure the stability of the support structure. Support plate two 3 is used to support the upper structure, including support seat 4 and support mechanism 5, and at the same time as a bridge connecting support plate one 2 and support mechanism 5. Support seat 4 provides additional support points for supporting the top of the mine. Support mechanism 5 is mainly used to stably support the two sides of the inner wall of the mine during the mining process to prevent the collapse of the mine and ensure the safe operation of the mining work. Support frame 51 is the main frame of support mechanism 5, which is fixedly connected to the middle of the lower surface of support plate two 3, providing a basis for the installation and support of other elements. Motor 52 is the power source, which drives threaded rod 53 to rotate, and slider one 54 moves on threaded rod 53, thereby driving the linkage of connecting rod 57 and slider two 55. Threaded rod 53 is a transmission element in support mechanism 5, which drives slider one 54 to move linearly through rotation. Slider one 54 is connected to threaded rod 53 through threads and moves linearly with the rotation of threaded rod 53. Connecting rod 57 connects slider one 54 and slider two 55, and through the transmission action of connecting rod 57, the movement of slider one 54 is converted into the movement of slider two 55, thereby driving support plate three 56 to adjust the support force. The movement of slider two 55 drives support plate three 56 to adjust and transmit the support force. Support plate three 56 is the final support surface of support mechanism 5, which transmits the support force through its contact with the inner wall of the mine, bears the pressure of the inner wall of the mine and prevents collapse.
[0029] As Figure 1As shown, the upper surface of the third support plate 56 is fixedly connected with a connecting plate 58, the middle part of the upper part of the second support plate 3 is fixedly connected with a protective net 7, and the opposite sides of the two protective nets 7 are fixedly connected with the opposite sides of the two connecting plates 58, respectively.
[0030] It should be noted that the connecting plate 58 is used to connect the third support plate 56 and the protective net 7, so that the protective net 7 moves with the third support plate 56. The protective net 7 prevents coal blocks or gravel produced during mining from splashing and injuring people, thereby improving the safety of the mining process.
[0031] As shown in the Figure 4 As shown, the inner cavity of the base 1 is movably connected with a fixing mechanism 6, the fixing mechanism 6 includes a sliding plate one 61, the outer periphery of the sliding plate one 61 is slidably connected in the inner cavity of the base 1, the lower surface of the sliding plate one 61 is fixedly connected with a plurality of anchor columns 62 distributed in a rectangular shape, the middle parts of the left and right sides of the sliding plate one 61 are fixedly connected with a sliding plate two 64, the lower part of the first support plate 2 is fixedly connected with an electric push rod 65, and the output end of the electric push rod 65 is fixedly connected with the upper surface of the sliding plate two 64.
[0032] It should be noted that the fixing mechanism 6 pushes the anchor columns 62 to insert into the ground through the electric push rod 65, so as to realize the stable fixation of the support on the ground and ensure the safe operation of the mining work. The sliding plate one 61 is slidably connected in the inner cavity of the base 1, so as to realize the movement in the vertical direction, and the plurality of anchor columns 62 fixedly connected with the lower surface of the sliding plate one 61 can provide fixing force after being inserted into the ground. The anchor columns 62 are inserted into the ground and deep into the soil layer, so as to realize the stable fixation of the support. The anchor columns 62 are designed in a sharp conical shape, so as to be easily inserted into the ground. The electric push rod 65 serves as a power source, and moves downward by pushing the sliding plate one 61 and the anchor columns 62, so as to realize the fixation of the support. The sliding plate two 64 serves as a fixed point of the output end of the electric push rod 65.
[0033] As shown in the Figure 5 As shown, the inner cavity of the base 1 is fixedly connected with two limiting rods 66 distributed left and right, the sliding plate one 61 is slidably connected with the outer periphery of the limiting rod 66, the lower surface of the limiting rod 66 is fixedly connected with a limiting plate 67, and the middle part of the bottom of the inner cavity of the base 1 is fixedly connected with a baffle 63.
[0034] It should be noted that the limiting rod 66 and the limiting plate 67 are used to limit the movement range of the sliding plate one 61, so as to ensure the stability and accuracy of the fixing mechanism 6 during the movement. The baffle 63 is used to prevent the sliding plate one 61 from being separated and limit the movement range of the sliding plate one 61.
[0035] As shown in the Figure 2 As shown, the front and rear sides of the lower part of the base 1 are rotatably connected with a plurality of moving wheels 8 distributed in a rectangular shape.
[0036] It should be noted that the moving wheels 8 facilitate the movement and position adjustment of the support in the mining site.
[0037] As Figure 1 shown, the base 1 is isosceles trapezoidal, and the front and rear sides of the base 1 are inclined downward.
[0038] It should be noted that the base 1 is isosceles trapezoidal, and the front and rear sides are inclined downward, which helps the support to remain stable on uneven ground, and is convenient for moving and adjusting the position.
[0039] As Figure 4 shown, a sliding groove is formed in the middle of the upper part of the support plate 1, and the outer periphery of the sliding block 2 is slidingly connected in the sliding groove.
[0040] It should be noted that the sliding groove in the upper part of the support plate 1 is used to limit the movement trajectory of the sliding block 2, and to ensure that the sliding block 2 stably slides on the upper part of the support plate 1.
[0041] The working principle of the utility model is as follows: first, when the inner wall of the mine needs to be supported, the motor 52 is started to drive the threaded rod 53 to rotate, and this rotating action is transmitted to the sliding block 1 through the threaded connection, so that the sliding block 1 moves linearly along the threaded rod 53. The movement of the sliding block 1 further transmits the action of the connecting rod 57, which drives the sliding block 2 to move linearly in the opposite direction in the sliding groove in the upper part of the support plate 1. The movement of the sliding block 2 ultimately causes the support plate 3 to tightly adhere to the inner wall of the mine, realizing a stable supporting effect and effectively bearing the pressure from the inner wall of the mine and preventing collapse. In order to enhance the stability of the support on the ground, the electric push rod 65 is started to push the sliding plate 1 and the anchor column 62 thereon to move downward until the anchor column 62 penetrates into the soil layer, realizing the stable fixation of the ground. In this process, the limiting rod 66 and the limiting plate 67 work together to ensure the stable sliding of the sliding plate 1 in the inner cavity of the base 1 and prevent it from exceeding the predetermined movement range. The baffle 63 further enhances the stability of this fixation mechanism. The connecting plate 58 connects the protective net 7 with the support plate 3, ensuring that the protective net 7 can move with the support plate 3, effectively blocking the flying of coal or gravel that may be generated during the mining process, thereby avoiding harm to the workers. The front and rear sides of the lower part of the base 1 are rotatably connected with a plurality of moving wheels 8, so that the entire support can be easily transferred and adjusted between different positions.
[0042] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
