Meanwhile, the stop bolt has a guiding effect in the guide groove of the slide guide, so that the slide guide can operate freely when it extends and retracts. The slide guide is a cylinder, and the end with a large diameter is provided with a fixing hole, which is connected with the guide seat of the movable side guard through the slide guide fixing pin, so as to drive the movable side guard to move back and forth. The other end of the slide guide with a small diameter can extend into the cylindrical spiral spring. The stepped surface formed by the small rod diameter and the large rod diameter is the positioning surface of the cylindrical spiral spring. The purpose of driving the slide guide by the cylindrical spiral spring and driving the spiral spring by the slide guide under the action of the side pushing jack is achieved. The slide guide extending into the spiral spring is provided with a slide at one side. The slide has the fixed position A and the fixed position B at two ends. The elastic steel rod placed at the fixed position A realizes the locking of the extending of the movable side guard, and the elastic steel rod placed at the fixed position B realizes the locking of the retracting of the movable side guard. When the mine is transported, the elastic steel rod is placed at the fixed position B, and the movable side guard is in the retracting locking state. At this time, the width of the hydraulic support beam body is the smallest, so as to facilitate the transportation in the mine. When the mine is produced, the elastic steel rod is placed at the fixed position A. At this time, the control valve for controlling the operation of the side pushing jack is in the middle position. The piston cavity and the piston rod cavity of the side pushing jack are communicated with the liquid return pipeline, and the side pushing jack is in the follow-up state. The side pushing jack basically has no side pushing force. Under the elastic force of the spiral spring, the elastic steel rod can freely slide in the slide according to the different distances between the frames, so as to realize the frame sealing of the hydraulic support. The slide guide has the guide groove, which cooperates with the stop bolt to prevent the rotation of the slide guide and achieve the guiding effect when the slide guide moves back and forth. The elastic steel rod is a cylinder with a certain elasticity and is fixed at one end in the fixed seat.The other end can be hooked to the fixed position A or fixed position B of the slide guide, and can slide freely in the slide, realizing the locking function and back-and-forth action of the slide guide, and realizing the locking and back-and-forth movement function of the movable side guard. The fixed seat has a conical surface which can extend into the spiral spring, and the end of the conical surface is provided with a stepped surface as a positioning surface of the spiral spring. The fixed seat has a fixed hole, and one end of the self-locking elastic steel rod is inserted into the hole to fix the slide guide, and the other end has a thread which passes through the center hole of the sealing plate and is connected by a thread to fix the self-locking elastic steel rod and the spiral spring in the sleeve. The outermost end of the fixed seat with a thread is provided with a fixed hole, and the fixed pin shaft on the beam body passes through the fixed hole of the fixed seat to fix the solid of the one-piece one-way operation self-locking movable side guard fixing device in the beam body. One end of the sleeve is provided with a sealing plate which is fixed to the end of the sleeve by welding. The center of the sealing plate is provided with a thread, and the end of the fixed seat with a thread passes through the sealing plate and is connected by a thread to realize the end packaging of the one-piece one-way operation self-locking movable side guard fixing device. One end of the sleeve is provided with a sealing plate which is fixed to the end of the sleeve. The slide guide, cylindrical spiral spring, self-locking elastic steel rod and fixed seat are all packaged in the sleeve. The sealing plate fixes the fixed seat by thread connection. The other end of the sleeve is provided with a stop bolt which extends into the guide groove of the slide guide to prevent the rotation of the slide guide, realizing the overall packaging of the one-piece one-way operation self-locking movable side guard fixing device. The side pushing jack is separate from the self-locking movable side guard fixing device and is arranged in parallel. The side pushing jack only takes the one-way action of retraction, and the action direction is consistent with the compressible direction of the ordinary cylindrical spiral spring. The maximum stroke of the side pushing jack cannot exceed the maximum compression amount of the cylindrical spring. The length of the slide of the slide guide exceeds the maximum stroke of the side pushing jack. When the movable side guard is retracted and locked, the ordinary cylindrical spiral spring still has a certain compressible amount. The side pushing jack still has a small stroke at this time. If the movable side guard needs to be extended, the operation control valve is operated to make the side pushing jack act. The beam body has a movable side guard limiting device to protect the side pushing jack from over operation. When the movable side guard is retracted to the limiting state, the operation control valve which controls the action of the side pushing jack is placed in the middle position. At this time, when the self-locking elastic steel rod is popped up from the slide fixed position B and the spiral spring is popped out, the side pushing jack is in a follow-up state. The spiral spring pushes the slide guide to move outward, and the slide guide pushes the movable side guard to move outward, realizing the extension action of the movable side guard. If there is no adjacent support for limiting, the slide guide directly runs to the slide fixed position A. If there is an adjacent support for limiting, according to the different distance between the supports, the self-locking elastic steel rod automatically slides in the slide of the slide guide, realizing the inter-support sealing of the hydraulic support.
