Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic supports, and in particular relates to a side guard plate structure used for a hydraulic support. Background Art

[0002] The shielded hydraulic support is an important equipment for comprehensive mechanized coal mining. It is used to maintain the roof of the coal mining face and isolate the goaf, providing a safe working space for coal mining machines, conveyors and workers. It can also push the working face conveyor to move toward the coal wall. At the same time, the conveyor can be used as a fulcrum to achieve self-movement of the support, thereby realizing comprehensive mechanized coal mining, solving the contradiction that the roof management lags behind the coal mining face in mechanized coal mining work, and further improving and enhancing the efficiency of coal mining and transportation equipment.

[0003] The top beam is an important component of the hydraulic support, and the top beam side guard plate is an important component of the top beam, which makes the top beams of two adjacent frames fit closely together. The existing side guard plates are generally fixed on the side walls of the top beam by a large number of bolts, which makes installation and disassembly more troublesome. In addition, the setting of the bolts makes it easy for the outer ends of the side guard plates to bulge, so that when the side walls of two hydraulic supports are butt-jointed, gaps are easily generated at the joints, causing gangue to fall from the gaps, affecting the safety of underground workers. For this reason, we propose a side guard plate structure for a hydraulic support. Utility Model Content

[0004] The purpose of the utility model is to provide a side guard plate structure for a hydraulic support to solve the problems raised in the above background technology.

[0006] Preferably, a surface of the plug-in plate located inside the top beam and a corner of the locking plate close to the side guard plate are both provided with arc-shaped surfaces.

[0007] Preferably, an ejection mechanism is provided inside the top beam, and the ejection mechanism includes threaded rod one and threaded rod two, and threaded rod one and threaded rod two are rotatably installed inside the top beam, the lower end of threaded rod one is connected to the upper end of threaded rod two, and the circumferential surfaces of threaded rod one and threaded rod two are threadedly connected with ejection plates, and the ends of the two ejection plates away from the threaded rods are in the same vertical plane with the limiting plate.

[0009] Preferably, sealing plates are hinged inside both left and right ends of the top beam, and four sealing plates are provided, and the four sealing plates are respectively abutted against upper and lower sides of the two plug-in plates.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) The side guard plate structure for the hydraulic support can quickly install or remove the side guard plate through the plug-in mechanism, without the need to install and fix the side guard plate with a large number of bolts. The operation is simple and quick. At the same time, the side wall of the side guard plate will not have bulges, so that when multiple hydraulic supports are docked with each other, it is not easy to produce gaps at the docking points, which prevents gangue from falling from the gaps and improves safety during work.

[0012] (2) The side guard plate structure for the hydraulic support can be equipped with an ejection mechanism. When the side guard plate is disassembled, after the locking plate is moved out of the plug-in plate, the ejection mechanism can eject the plug-in plate and the side guard plate from the inside of the top beam, thereby facilitating the staff to take out the side guard plate from the inside of the top beam.

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1 - Figure 4 The utility model provides a side guard plate structure for a hydraulic support, including a top beam 1, and side guard plates 2 are plugged into the left and right sides of the top beam 1 through a plug-in mechanism 4. The plug-in mechanism 4 includes a plug-in plate 401 and a locking plate 402, and two locking plates 402 are symmetrically arranged up and down. One end of the plug-in plate 401 is fixedly connected to the inner surface of the side guard plate 2. The locking plate 402 can limit and fix the plug-in plate 401 after the plug-in plate 401 is plugged into the inside of the top beam 1, so that the side guard plate 2 is fixed to the top beam 1 through the plug-in plate 401. The other end of the plug-in plate 401 is plugged into the inside of the top beam 1, and one end of the two locking plates 402 is respectively plugged into the upper and lower ends of the plug-in plate 401. The surfaces of the upper and lower ends of 1 are provided with slots matching the locking plates 402, so that the locking plates 402 can be smoothly plugged into the inside of the plug-in board 401, and the other ends of the two locking plates 402 are movably installed in the inside of the top beam 1 through the compression springs 403. The setting of the compression springs 403 enables the locking plates 402 to move vertically, thereby facilitating the plug-in board 401 to be inserted into or removed from the inside of the top beam 1. Limiting plates 404 are provided on the left and right sides of the locking plates 402 away from one end of the plug-in board 401. The limiting plates 404 can limit the plug-in board 401, so that the plug-in board 401 can move vertically stably, and avoid the position deviation of the plug-in board 401 affecting its use;

[0020] Among them, a side of the plug-in plate 401 located inside the top beam 1 and a corner of the locking plate 402 close to the side guard plate 2 are both provided with an arc surface 405. The setting of the arc surface 405 on the surface of the plug-in plate 401 and the locking plate 402 enables the plug-in plate 401 to push the locking plate 402 toward the inside of the top beam 1 after the plug-in plate 401 is inserted into the inside of the top beam 1. Then, after the plug-in plate 401 is inserted into the inside of the top beam 1 as a whole, the locking plate 402 is plugged into the inside of the plug-in plate 401 under the action of the compression spring 403. Due to the setting of the vertical surface on the other side of the locking plate 402, the locking plate 402 can be stably clamped in the inside of the plug-in plate 401, thereby achieving the fixing effect of the plug-in plate 401.

[0021] The top beam 1 is provided with an ejection mechanism 3, which includes a threaded rod 1 301 and a threaded rod 2 302, and the threaded rod 1 301 and the threaded rod 2 302 are both rotatably mounted inside the top beam 1, the lower end of the threaded rod 1 301 is connected to the upper end of the threaded rod 2 302, and the circumferential surfaces of the threaded rod 1 301 and the threaded rod 2 302 are both threadedly connected with an ejection plate 303, and the threads on the surfaces of the threaded rod 1 301 and the threaded rod 2 302 are arranged in opposite directions, so that the ejection mechanism 3 can be rotated between the threaded rod 1 301 and the threaded rod 2 When the two 302 rotate synchronously, the two ejector plates 303 on the surface can move vertically in opposite directions. The ends of the two ejector plates 303 away from the threaded rods are in the same vertical plane as the limiting plate 404, so that when the ejector plates 303 move toward the limiting plate 404, they can approach and abut the limiting plate 404, thereby driving the limiting plate 404 away from the plug-in board 401, and then pushing the locking plate 402 out of the plug-in board 401, so that the locking plate 402 loses the limiting and fixing effect on the plug-in board 401;

[0022] Among them, ejection springs 6 are arranged inside the left and right sides of the top beam 1, and push plates 5 are arranged at the outer ends of the two ejection springs 6. The outer ends of the two push plates 5 are respectively abutted against the two plug-in plates 401. After the plug-in plates 401 are fully plugged into the top beam 1 and the locking plates 402 are plugged into the plug-in plates 401, the ejection springs 6 are in a compressed state. The ejection springs 6 will apply a thrust to the push plates 5, so that the push plates 5 apply a thrust to the plug-in plates 401, thereby making the contact between the plug-in plates 401 and the locking plates 402 closer, further improving the clamping and limiting effect of the locking plates 402.

[0023] Sealing plates 7 are hinged inside the left and right ends of the top beam 1, and there are four sealing plates 7, which are respectively abutted against the upper and lower sides of the two plug-in plates 401. The setting of the sealing plates 7 can close the slots on both sides of the top beam 1 when the side guard plates 2 have not yet been installed on the side walls of the top beam 1, thereby preventing external dust and impurities from entering the interior of the top beam 1, and then clogging the slots and affecting the subsequent installation of the side guard plates 2.

[0024] The working principle and use process of the utility model are as follows: when the side guard plate 2 is deformed and needs to be replaced, the threaded rod 1 301 and the threaded rod 2 302 are first rotated to make the two ejection plates 303 move away from each other, and then the left and right ends of the ejection plate 303 respectively approach and abut the limit plates 404 on the left and right sides, and then the ejection plate 303 continues to move to drive the limit plates 404 away from the plug-in plate 401, and the limit plates 404 move to drive the locking plates 402 to move out from the inside of the plug-in plate 401, so that the locking plates 402 lose the limiting and fixing effect on the plug-in plate 401, and at this time, the elastic force of the ejection spring 6 is released, and the plug-in plate 401 is pushed out from the inside of the top beam 1 through the push plate 5, and then the side guard plate 2 is removed from the top beam 1, and then the threaded rod 1 301 and the threaded rod 2 302 are rotated in the opposite direction to reset the ejection plate 303;

[0025] Then, the new side guard plate 2 is plugged into the side wall of the top beam 1 through the plug-in plate 401. During the process of inserting the plug-in plate 401 into the top beam 1, the locking plate 402 will be pushed into the top beam 1 first. Then, after the plug-in plate 401 is completely inserted into the top beam 1, the locking plate 402 is inserted into the plug-in plate 401 under the elastic force of the compression spring 403, thereby completing the installation of the side guard plate 2.

[0026] 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.
