DETAILED DESCRIPTION
[0023] 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.
[0024] Example
[0025] See also Figure 1-4 A supporting and reinforcing device includes a bottom supporting structure and a top supporting structure, wherein the bottom supporting structure includes a supporting plate 1, a plurality of hydraulic cylinders 2 are fixedly mounted on the top of the supporting plate 1, and a plurality of universal wheels 3 are fixedly mounted on the bottom of the supporting plate 1.
[0026] By providing the universal wheels 3, the device can be easily moved, thus improving the convenience of using the device.
[0027] The top supporting structure includes a supporting plate 2 4, which is fixedly connected to the top of the hydraulic cylinder 1 2. The top of the supporting plate 2 4 is fixedly connected to two fixed blocks 5. The side ends of the fixed blocks 5 are rotatably provided with rotating blocks 6. A limiting structure is provided between the rotating blocks 6 and the fixed blocks 5. The top of the rotating block 6 is fixedly installed with a hydraulic cylinder 2 7, and the output end of the hydraulic cylinder 2 7 is fixedly connected to a supporting plate 3 8.
[0028] The staff can stand on the top of the support plate 2 4 to carry out backfilling operations. At the same time, starting the hydraulic cylinder 1 2 can drive the support plate 2 4 to move, which makes it convenient to transport the workers to a suitable working height, which is beneficial to improving work efficiency. At the same time, starting the hydraulic cylinder 2 7 can move the support plate 3 8 so that the support plate 3 8 contacts the surrounding rock, which can provide a supporting effect on the surrounding rock and facilitate subsequent backfilling operations. At the same time, since the rotating block 6 can rotate, it is convenient to adjust the angle of the support plate 3 8, which is beneficial to increasing the scope of use and thereby improving the applicability of the device, wherein the limiting structure is responsible for fixing the angle of the support plate 3 8.
[0029] The limiting structure includes a slide plate 9 and a socket 10. The socket 10 is opened on the outer wall of the fixed block 5. The slide plate 9 is slidably set inside the rotating block 6. The bottom end of the slide plate 9 is fixedly connected with an insertion rod 11, and the insertion rod 11 is plugged into the socket 10. A spring 12 is arranged between the slide plate 9 and the inner wall of the rotating block 6. The top end of the slide plate 9 is fixedly connected with a connecting rod 13, and the top end of the connecting rod 13 is fixedly connected with a handle 14.
[0030] By pulling the handle 14, the slide plate 9 can be driven to move under the connection action of the connecting rod 13, so that the insertion rod 11 is disengaged from the socket 10, thereby facilitating the rotation of the rotating block 6. At the same time, after loosening the handle 14, the slide plate 9 can drive the insertion rod 11 to be reinserted into the socket 10 under the action of the spring 12, thereby fixing the rotating block 6, thereby achieving the effect of fixing the angle of the support plate 3 8.
[0031] See also Figure 2 A plurality of jacks 10 are evenly arranged on the outer wall of the fixing block 5 .
[0032] Since there are multiple jacks 10, it is convenient to fix the support plate 3 8 at multiple angles.
[0033] See also Figure 4 The bottom end of the slide plate 9 is fixedly connected to a limiting block 15 , and the limiting block 15 is plugged and matched with the rotating block 6 .
[0034] During the upward movement of the slide plate 9, the limit block 15 moves accordingly until it is no longer connected with the rotating block 6. Thereafter, the handle 14 can be rotated at a certain angle to allow the limit block 15 to rotate under the connection between the connecting rod 13 and the slide plate 9. When the handle 14 is released, the limit block 15 can be pressed against the inside of the rotating block 6 under the action of the spring 12 and will not be inserted into the inside of the rotating block 6, thereby preventing the insertion rod 11 from being inserted into the inside of the socket 10, making it convenient to rotate the rotating block 6 in practice.
[0035] See also Figure 3 A slide bar 16 is slidably arranged inside the support plate 3 8 , a support plate 4 17 is fixedly connected to the side wall of the slide bar 16 , and a handle 2 18 is fixedly connected to the bottom end of the slide bar 16 .
[0036] By moving the handle 2 18, the support plate 4 17 can be driven to move under the connection of the slide rod 16, which can increase the support range, thereby improving the applicability of the device and making the device more convenient to use.
[0037] See also Figure 3 A limiting rod 19 is fixedly connected to the side wall of the supporting plate 4 17 , and the limiting rod 19 is slidably arranged inside the supporting plate 3 8 .
[0038] The limiting rod 19 can provide a limiting support effect on the support plate four 17, making the support plate four 17 more stable.
[0039] See also Figure 1 A guardrail 20 is fixedly installed on the top of the supporting plate 24.
[0040] The guardrail 20 provides good protection for the staff at the top of the support plate 24, which is beneficial to improving the safety of the device.
[0041] In summary, the working principle and working process of the support and reinforcement device are as follows: when in use, the support and reinforcement device is first moved to the desired location, and then the staff can stand on the top of the support plate 2 4, and then start the hydraulic cylinder 1 2 until the staff rises to a suitable working height, and then move the handle 14 upward, and then rotate the rotating block 6 until the support plate 3 8 is rotated to a suitable angle, release the handle 14, and slide the handle 2 18 until the support plate 4 17 moves to a suitable position, and finally start the hydraulic cylinder 2 7, so that the support plates 3 8 and the support plates 4 17 support and reinforce the surrounding rocks, and then the subsequent backfilling operation can be carried out. The device is relatively convenient to use, has high applicability, is convenient for backfilling operations, and has high practicality.
[0042] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
