[0011] Furthermore, a step surface corresponding to the upper end surface of the outer arc plate is provided on the upper outer surface of the left support plate and the right support plate, and the auxiliary support mechanism is provided on the outer surface above the step surface.

[0012] Furthermore, distance sensors with outward sensing directions are provided on the upper parts of the left and right support columns.

[0023] by Figure 1 The up, down, left, right, front and back directions of this embodiment are defined.

[0024] As shown in the figure, this embodiment includes a left support column 1, with a right support column 2 positioned to the right of the left support column 1. Universal wheels 3 are installed at the lower ends of both support columns, enabling free movement. The upper portions of the left and right support columns are connected to each other via a transverse telescopic mechanism. This mechanism includes a left support slide 4 and a right support slide 5, each of which has its outer ends fixed to the left and right support columns. The lower portions of the left and right support slides have grooves defined at their outer ends, and the upper ends of the left and right support columns are respectively inserted into the grooves at the outer ends of the left and right support slides and secured by bolts. A connecting base 6 is located above the left and right support slides. Each of the left and right support slides has a slot that matches the connecting base 6, allowing the lower portion of the connecting base 6 to slide with the two support slides during use. An upward-facing column 7 is located at the upper end of the connecting base 6, the lower end of which is bolted to the connecting base 6. Stabilizing brackets 8 are located on either side of the column 7. The upper and lower ends of the stabilizing brackets 8 are bolted to the column 7 and the connecting base 6, respectively, enhancing the stability of the column 7. A vertical first hydraulic cylinder 9 is provided at the upper end of the column 7, and the lower end of the cylinder body of the first hydraulic cylinder 9 is fixedly connected to the column 7. Second hydraulic cylinders 10 are provided on both the left and right sides of the connecting seat 6, and the cylinder bodies of the two second hydraulic cylinders 10 are fixedly connected to the left and right end faces of the connecting seat 6 by bolts. The piston rods of the two second hydraulic cylinders 10 are respectively fixedly connected to the left and right support slides. When in use, starting the second hydraulic cylinders can control the left and right support slides to move outward. In this embodiment, the side of the device close to the column 7 in the left and right directions is defined as the inner side of this embodiment, and the side away from the column 7 is defined as the outer side of this embodiment.

[0025] A cave roof support mechanism is located above the left and right support columns. This mechanism includes inner arc plates 12 positioned relative to the left and right support slides. The lower end of each inner arc plate 12 is fixedly connected to the upper surface of each support slide. An outer arc plate 11 is located on the outer side of each inner arc plate 12, with a gap between each outer arc plate 11 and the inner arc plate 12. The lower end of each outer arc plate 11 is pivotally connected to the upper end of the left and right support slides via a hinge. Adjustment bolts 13 are located between the outer and inner arc plates 11, 12. In this embodiment, two sets of adjustment bolts 13 are provided on each side, symmetrically arranged along the front and back of the outer arc plate 11. The outer side of each adjustment bolt 13 is embedded in and fixedly connected to the outer arc plate 11 to prevent it from interfering with the contact between the outer arc plate 11 and the cave body. The screw of each adjustment bolt 13 extends inward through the inner arc plate 12 and is screwed onto a nut on the inner side of the inner arc plate 12. The nut adopts a different-diameter nut structure, and a T-shaped slot corresponding to the position of the adjustment bolt 13 is provided on the inner side of the inner arc plate 12; the stepped surface structure of the nut matches the T-shaped slot and can slide along the T-shaped slot. In this embodiment, the end of the nut with a smaller diameter is hexagonal and extends to the inner side of the inner arc plate 12 to facilitate the rotation of the nut. During installation, the nut is placed in the T-shaped slot and connected to the adjustment bolt 13 to support the outer arc plate 11. By rotating the nut, the outer arc plate 11 can be moved inward and outward to control the opening angle of the outer arc plate 11, so that the outer arc plate 11 matches the shape of the hole body and increases the contact area with the hole body. The front and rear sides of the left and right support slides are fixedly connected to the upper end of the inner arc plate 12 on the same side by a reinforcement rod 15, which can enhance the support strength of the inner arc plate 12. The gap between the outer arc plate 11 and the inner arc plate 12 forms a guide slot 14. The left and right guide slots 14 are provided with curved left and right support plates 16 and 17, respectively. These left and right support plates 16 and 17 can slide along the guide slots 14 and flexibly engage with the outer arc plate 11 and inner arc plate 12 on the same side. A hinge seat 18 is provided above the piston rod of the first hydraulic cylinder 9 and is fixedly connected to the piston rod of the first hydraulic cylinder 9. A hinge shaft is pivotally connected to the center of the hinge seat 18, protruding forward and backward from the hinge seat 18. The protruding portion is hingedly connected to the upper ends of the left and right support plates. Limiting slots 20 are defined at the lower portions of the left and right support plates. In this embodiment, the size and position of the limiting slots 20 correspond to the respective sets of adjusting bolts 13. When the left and right support plates move within the guide slots 14, the adjusting bolts 13 can limit the movement of the left and right support plates through the limiting slots 20. A top plate 19 is fixedly mounted on the upper end of the articulated seat 18 . The top plate 19 is arc-shaped. When in use, the first hydraulic cylinder 9 is activated to lift the top plate 19 to support the top of the cave body.

[0026] In this embodiment, a step surface corresponding to the upper end surface of the outer arc plate 11 is provided on the upper outer surface of the left support plate 16 and the right support plate 17. When the first and second hydraulic cylinders are recovered, the step surface structure of the left and right support plates contacts the outer arc plate 11, and the parts of the left and right support plates extending to the guide groove 14 can assist in supporting the outer arc plate 11.

[0027] An auxiliary support mechanism is provided on the outer surface of the outer arc plate 11 and the left and right support plates located outside the guide groove 14. The auxiliary support mechanism includes an auxiliary arc plate 23. In this embodiment, four auxiliary arc plates 23 are provided. Each auxiliary arc plate 23 is respectively provided on the outer surface above the upper part of the outer arc plate 11 and the step surface of the left and right support plates. A group of springs 24 are provided at the lower part of each auxiliary arc plate 23, which are fixedly connected to the outer surface above the upper part of the outer arc plate 11 and the step surface of the left and right support plates through the springs 24. When in use, the contact area between the device and the hole body can be increased, thereby playing a role of auxiliary support.

[0028] A spacer 21 is installed on the adjustment bolt 13 between the inner and outer arc plates 12 and 11. This spacer 21 is cylindrical and features a mounting slot 22, wider than the diameter of the adjustment bolt 13 and extending from its center to its circumference. During use, the spacer 21 is inserted into the adjustment bolt 13, positioning the adjustment bolt 13 within the mounting slot 22. This installation enhances the bearing strength of the outer arc plate 11. After installation, the spacer 21 can be rotated so that the mounting slot 22 faces downward, preventing it from falling. After the outer arc plate 11 has been adjusted in angle, if the guide slot 14 is narrow, one or two spacers 21 can be used to adequately support the outer arc plate 11. If the guide slot 14 is wide, a group of spacers 21 may be installed in series on the same adjustment bolt 13. Spacers 21 of varying thicknesses can be designed for use during construction, ensuring that the spacers 21 fill the guide slot 14 as closely as possible to ensure effective support for the outer arc plate 11. In this embodiment, three spacers 21 are mounted in series on the same adjusting bolt 13. The thickness of the spacers 21 on the inner and outer sides matches the thickness of the inner and outer arc plates 12 and 11, respectively. The thickness of the spacer 21 in the middle is greater than that of the spacers 21 on the inner and outer sides. A continuously undulating protrusion structure is provided in the guide groove 14. The spacers 21 on the inner and outer sides are flush with the protrusions, allowing the spacer 21 in the middle to be installed smoothly. When the left and right support plates extend into the guide groove 14, spacers 21 need to be installed on the upper and lower sides of the left and right support plates, respectively. The two support plates are squeezed and fixed, so that the top plate portion is connected to the arc plate structure on both sides to ensure the overall support strength of the device.

[0029] Distance sensors with outward sensing directions are respectively arranged above the left and right support columns. The first distance sensor 25 is fixedly mounted on the front end surface of the left support slide 4, and the second distance sensor 26 is fixedly mounted on the front end surface of the right support slide 5. The detection range is flush with the left and right end surfaces of the left and right support slides, and can determine whether the left and right support slides are in contact with the side of the cave body.

[0030] In this embodiment, two left support columns 1 and right support columns 2 are respectively provided on the left and right sides along the front-to-back direction. Each left and right support column is equipped with a transverse telescopic mechanism and a cave ceiling support mechanism. Each left support column 1 and right support column 2 is provided with a connector 27 with a socket. The left support columns 1 are fixedly connected to each other via a connecting rod 28 passing through the socket of the connector 27; the right support columns 2 are fixedly connected to each other via a connecting rod 28 passing through the socket of the connector 27. This connection of the left and right support columns improves the stability of each support column.

[0031] In this embodiment, the first hydraulic cylinder 9 and the two second hydraulic cylinders 10 are connected in stroke, and each hydraulic cylinder is connected to a hydraulic station 29. The hydraulic synchronous motor on the hydraulic station 29 synchronizes the three hydraulic cylinders to avoid uneven force. The hydraulic station 29 is also wirelessly connected to the first and second distance sensors, which can control the hydraulic station 29 to stop. The hydraulic station 29 adopts existing technology and will not be described in detail here.

[0032] To use this embodiment, first, push a set of left and right support columns equipped with a transverse telescopic mechanism and a cave roof support mechanism into the cave. After aligning the left and right support slides with the left and right sides of the cave, adjust the position and curvature of the outer arc plate 11 using the adjusting bolts 13 according to the shape of the cave roof to ensure it fits the cave. After this, activate the hydraulic station 29. The first hydraulic cylinder 9 pushes the top plate 19 upward, while the second hydraulic cylinders 10 push the left and right support slides outward. The three hydraulic cylinders operate synchronously. When both the first and second distance sensors detect the cave, they generate a signal to stop the hydraulic station 29. At this point, the left and right support slides contact the cave sides with the top plate. The universal wheels are then locked. After the spacers 21 are installed in the guide grooves 14, they are attached to the adjusting bolts 13. After the spacers 21 are installed, push the next set of devices into the cave, and repeat the above steps to support the cave. After this, connect the devices by installing connecting rods 28 in the sockets of the connectors 27 of each device.
