DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the following further describes the utility model in conjunction with specific embodiments.

[0026] As Figure 1 - Figure 5As shown in the figure, a thin coal seam hydraulic support pushing mechanism, including support seat 1, the upper part of the inner side of support seat 1 is fixedly connected with two front and rear distribution of the connecting block 2, the lower part of the inner side of support seat 1 is slidably connected with support plate 6, the upper surface of support plate 6 is fixedly connected with two front and rear distribution of the connecting plate 3 on the right side, the opposite side of two connecting blocks 2 and the opposite side of two connecting plates 3 are movably connected with connecting mechanism 4, the outer periphery of the opposite side of two connecting mechanisms 4 is fixedly connected with hydraulic cylinder 5;

[0027] Connecting mechanism 4 includes sleeve 41, the inner cavity of sleeve 41 is slidably connected with two front and rear distribution of the slide rod 42, the opposite side of two slide rods 42 is fixedly connected with the limiting plate 43, the inner cavity of the opposite side of two slide rods 42 is fixedly connected with compression spring 45, the outer periphery of the upper slide rod 42 is slidably connected in the inside of connecting block 2, the outer periphery of the lower slide rod 42 is slidably connected in the inside of connecting plate 3, the left and right ends of hydraulic cylinder 5 are fixedly connected with the outer periphery of sleeve 41.

[0028] It should be noted that support seat 1 is the basic support structure of the whole pushing mechanism, bearing various elements connected on the upper part and the inner side, ensuring the stability of the whole mechanism. Connecting block 2 is movably connected with connecting mechanism 4, which plays a role in transmitting the pushing force or pulling force generated by hydraulic cylinder 5. Support plate 6 is slidably connected on the lower part of the inner side of support seat 1, which serves as the support platform of connecting plate 3 and slide plate 7, and can be slid to adjust the position as needed to adapt to different working scenes. Connecting plate 3 is also movably connected with connecting mechanism 4, which works together with connecting block 2 to ensure that the pushing force or pulling force of hydraulic cylinder 5 can be evenly transmitted to support plate 6. Sleeve 41 is used to accommodate and support the sliding of slide rod 42, and the outer periphery of sleeve 41 is fixedly connected with hydraulic cylinder 5 to ensure that the power generated by hydraulic cylinder 5 can be stably transmitted to connecting mechanism 4. Slide rod 42 slides in the inside of connecting block 2 and connecting plate 3, thereby fixing connecting mechanism 4 in the middle of two connecting blocks 2 and two connecting plates 3. Limiting plate 43 is used to limit the sliding range of slide rod 42 in sleeve 41. Hydraulic cylinder 5 serves as the power source of the pushing mechanism, generating pushing force or pulling force through telescopic movement to push connecting mechanism 4 and support plate 6 to move.

[0029] As shown in the figure, Figure 4 The side of limiting plate 43 away from hydraulic cylinder 5 is fixedly connected with push block 44, the side of sleeve 41 away from hydraulic cylinder 5 is fixedly connected with baffle 46, push block 44 is slidably connected with the outer periphery of baffle 46, the inside of push block 44 is provided with sliding groove, and baffle 46 is slidably connected in the inside of sliding groove.

[0030] It needs to be explained that the dial block 44 is used to manually adjust the position of the slide rod 42 when needed. The compression spring 45 is fixedly connected in the inner cavity on the opposite side of the two slide rods 42, which plays a role of resetting, and is used to press the slide rod 42 to make it clamped in the inside of the connecting block 2 and the connecting plate 3. The baffle 46 is fixedly connected to the side of the sleeve 41 away from the hydraulic cylinder 5, which is used to limit the movement range of the dial block 44 and the limiting plate 43, and prevent damage caused by excessive sliding or impact.

[0031] As shown in Figure 3 , the inside of the support plate 6 is slidingly connected with the sliding plate 7, the left side of the sliding plate 7 is fixedly connected with the sliding rail 8, the right side of the sliding rail 8 is slidingly connected with the left side of the support plate 6, and the inside of the sliding rail 8 is movably connected with the fixing mechanism 9.

[0032] It needs to be explained that the sliding plate 7 is used to further support and fix other elements or structures. The fixed sliding rail 8 on the left side is slidingly connected with the left side of the support plate 6, which ensures that the sliding plate 7 can slide smoothly. The sliding rail 8 serves as a guide structure of the fixing mechanism 9, and the fixing mechanism 9 movably connected inside is used to fix and support other elements or structures.

[0033] As shown in Figure 5 , the fixing mechanism 9 comprises a threaded rod 92, the front and rear ends of the threaded rod 92 are rotatably connected inside the sliding rail 8, the inside of the sliding rail 8 is slidingly connected with two sliding blocks 93 distributed in front and back, the middle part of the sliding block 93 is threadedly connected with the outer periphery of the threaded rod 92, the left side of the sliding block 93 is fixedly connected with a clamping plate 94, and the opposite sides of the two clamping plates 94 are fixedly connected with shaft bodies 95.

[0034] It needs to be explained that the rotation of the threaded rod 92 can drive the sliding block 93 to slide inside the sliding rail 8, so as to realize the function of clamping and fixing other structures. When the threaded rod 92 rotates, the sliding block 93 will slide along the threaded rod 92, and the sliding position of the sliding block 93 determines the clamping position and force of the clamping plate 94, so as to realize the fixation of structures of different sizes. The clamping plate 94 serves as a clamping element for clamping and fixing other structures. The shaft body 95 can be inserted into the inside of the connected structure to enhance the stability of the connection.

[0035] As shown in Figure 3 , the middle part of the right part of the support seat 1 is rotatably connected with two rollers 10 distributed upward and downward.

[0036] It needs to be explained that the rollers 10 are used to reduce the frictional resistance of the pushing mechanism during movement, improve the moving efficiency and stability.

[0037] As shown in Figure 5 , the front and rear ends of the threaded rod 92 are fixedly connected with knobs 91.

[0038] It should be noted that the knob 91 is used as an interface for user operation, for manually rotating the threaded rod 92.

[0039] As shown in Figure 4 The recess 47 is arranged on the side of the push block 44 away from the limiting plate 43.

[0040] It should be noted that the recess 47 is used for facilitating the movement of the push block 44.

[0041] The working principle of the utility model is as follows: when the support is not started, the hydraulic cylinder 5 is in the contraction state, the slide rod 42 in the connecting mechanism 4 is clamped in the inside of the connecting block 2 and the connecting plate 3 under the action of the compression spring 45, the stability of the whole pushing mechanism is kept. When the support needs to be pushed, the hydraulic cylinder 5 starts to lengthen, the sleeve 41 and the slide rod 42 connected therewith move together, the roller 10 starts to roll, and the frictional resistance in the pushing process is reduced. When the hydraulic cylinder 5 needs to be replaced, the slide block 44 is slid through the recess 47 to make the slide rod 42 separate from the connecting block 2 and the connecting plate 3, then the hydraulic cylinder 5 is taken down to be replaced and maintained. When the pushing mechanism and other mechanisms are connected, the clamping plate 94 is placed on the two sides of the mechanism to be connected, then the knob 91 is rotated to make the slide block 93 drive the clamping plate 94 to move towards each other, so that the shaft body 95 is inserted into the inside of the other mechanism, and the connection stability between the mechanisms is ensured.

[0042] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by the person skilled in the art that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and the description in the specification are only used to illustrate the principle of the utility model, under the premise of not departing from the spirit and scope of the utility model, the utility model can have various changes and improvements, and these changes and improvements all fall into the scope of the utility model claimed for protection.
