[0026] Please refer to Figure 1 The embodiment provides a hydraulic support side guard plate rapid direction adjusting tool, which comprises at least one machining unit. The machining unit comprises a base 1, two fixed plates 2 and a jack 3. The base 1 is in the shape of a long strip, and the two ends of the base 1 extend to the two sides of the hydraulic support. The two fixed plates 2 are fixed at the two ends of the base 1 in the length direction. Specifically, the fixed plate 2 is L-shaped, and one side of the fixed plate 2 is connected to the upper surface of the base 1 and locked to the base 1 through a plurality of bolts, so that the other side of the fixed plate 2 is perpendicular to the base 1. In order to ensure that the vertical sides of the two fixed plates 2 have sufficient strength during work, a reinforcing rib 4 is further connected to the fixed plate 2. The jack 3 can be a conventional hydraulic jack 3, and the hydraulic power source thereof can come from a hydraulic pump station in a workshop or a mobile hydraulic pump station. The cylinder body of the jack 3 is fixedly connected to the vertical surface of one of the fixed plates 2, so that the jack 3 is arranged in parallel with the base 1 as a whole. The top rod of the jack 3 is arranged towards the other fixed plate 2, so that the end of the top rod and the vertical surface of the fixed plate 2 form a clamping surface for clamping the side guard plates on the two sides of the hydraulic support. A rubber layer is arranged on the clamping surface to reduce mechanical damage. In order to ensure the stable connection between the jack 3 and the fixed plate 2, a reinforcing rib 4 can also be arranged between the cylinder body of the jack 3 and the fixed plate 2.

[0027] In another embodiment, as shown in Fig. Figure 2 Two walking wheels 5 at one end are fixed wheels, and the other two are universal wheels. The walking wheels 5 make it easier to move the base 1. The support legs 6 are near the corresponding walking wheels 5 and are used to raise or lower the height of the base 1, so that the walking wheels 5 are in contact with or away from the ground. The support legs 6 can be hydraulic cylinders, and the power source is the same as that of the jack 3. Relative to the ground, when the support leg 6 is retracted, the bottom of the support leg 6 is higher than the bottom of the walking wheel 5, and the walking wheel 5 is in contact with the ground; when the support leg 6 is extended, the bottom of the support leg 6 is in contact with the ground, and the base 1 is lifted, so that the walking wheel 5 is away from the ground. The base 1 is placed on the ground by the support leg 6, which is not easy to move relative to the walking wheel 5. When facing uneven ground, by independently adjusting the height of the four support legs 6, the base 1 can be made to tend to be horizontal, making it more stable when working.

[0028] In another embodiment, two lifting lugs 7 are fixed on the side of the two fixed plates 2 away from each other. The lifting lugs 7 can be tied with ropes, chains, etc., to assist in moving the base 1, or to fix the fast steering tool when it is used. For large hydraulic supports, the length of the side guard plate is longer, so that the machining unit can support the side guard plate more stably. At this time, two or more machining units need to be used in cooperation. The spacing between adjacent bases 1 is 100-150 cm. In addition, according to the actual situation on site, the size of the machining unit is not limited. In the machining unit, the length of the base 1 can be set to 2-5 m, the width can be set to 30-50 cm, and the thickness can be set to 4-10 cm. The height of the fixed plate 2 relative to the base 1 can be set to 30-50 cm. The cylinder length of the jack 3 can be set to 30-100 cm.

[0029] The working principle of the utility model is as follows: Figure 3As shown, the base 1 is placed horizontally on the ground. If multiple bases 1 are used, the multiple bases 1 are aligned front to back and left to right, and are spaced 150 cm apart left and right. The hydraulic support roof beam or cover beam that needs to be adjusted or replaced is placed above the base 1, and then the jack 3 is controlled to extend against the movable side guard plate 8 of the hydraulic support. The fixed plate 2 at the end of the base 1 away from the jack 3 is against the fixed side guard plate of the hydraulic support. After confirming that the jack 3 and the fixed plate 2 are against the two side guard plates of the hydraulic support, the limiting pins of the two side guard plates are removed. At this time, the main function of the hydraulic support side guard plate quick adjustment tool is to prevent the side guard plate from being instantly opened under the elastic action of the spring cylinder (the spring cylinder is in a compressed state) after the limiting pins are removed. Then, the corresponding pin shaft, limiting pin, telescopic jack 3 and other parts are removed to remove the movable side guard plate 8 and the fixed side guard plate from the hydraulic support. The removed movable side guard plate 8 and the fixed side guard plate are adjusted, and then the two side guard plates are adjusted against the hydraulic support using the jack 3 and the fixed plate 2, and the limiting pins and other parts are installed. After the installation is completed, the adjustment of the movable side guard plate 8 and the fixed side guard plate is completed. Through the use of the hydraulic support side guard plate quick adjustment tool on site, the efficiency of adjusting the side guard plate is obviously improved, and the safety factor is improved by 80%, the occurrence of accidents is reduced, and the safety and economic benefits are improved.
