Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding technology for inductive proximity switches, and in particular to a mine support reinforcement device. Background Technology
[0002] Mine pillars are a portion of the ore body left behind during mining operations to protect personnel safety and the integrity of the tunnels. They are divided into permanent pillars and temporary pillars. To ensure stability, mine pillars sometimes need to be further reinforced.
[0003] Therefore, a mine support reinforcement device, with publication number CN218522325U, is used in which the support body is installed and fixed in a suitable position, and then the left and right locking rings are fastened to the lower end of the support body surface. The contact area between the support body and the ground is increased by the left and right support plates, and the reinforcement plate and anti-slip plate are set to increase the contact friction with the ground, thereby increasing its bearing area. At the same time, by turning the crank, the threaded rod is driven to rotate. The threaded engagement between the threaded rod and the threaded block, and the sliding of the slider in the groove, make the barbed rivets descend more smoothly and lock into the soil, thereby improving the support stability of the support body.
[0004] However, since the base of the pillar is partially embedded in the ground, its stability is relatively good. Therefore, the existing technology further reinforces the base area of the pillar, but does not protect the middle or even the upper part of the pillar. As a result, cracks are likely to appear in the middle or upper part of the pillar when it is impacted. Utility Model Content

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] like Figure 1-5As shown, a mine support reinforcement device includes a support body 1. A detachable fixed seat 2 is fitted onto the support body 1 near its bottom edge. Several detachable movable seats 8, fitted onto the support body 1, are stacked on the fixed seat 2. Both the fixed seat 2 and the movable seats 8 are composed of two semi-circular rings, with connecting bolts 13 embedded in the opposite end faces of the two semi-circular rings. The connecting bolts 13 are used to combine the symmetrically arranged semi-circular rings into a complete ring, which is then installed on the support body 1, thus enabling the installation of either the fixed seat 2 or the movable seats 8. A screw rod 9, corresponding to the number of movable seats 8, is rotatably connected through the upper surface of the fixed seat 2. The screw rods 9 are vertically arranged and pass through the end faces of the stacked movable seats 8. Each movable seat 8 mates with one of the screw rods 9 and is threadedly connected to the mating screw rod 9; that is, one screw rod 9 corresponds to one movable seat 8. The movable seats 8 are fitted onto the support body 1 and cannot be rotated due to the connecting bolts 13. When the movable seat 8 cannot rotate due to its connection with other lead screws 9, rotating the corresponding lead screw 9 allows the movable seat 8 to rise along the surface of the support body 1. This facilitates the installation of the movable seat 8 on the support body 1, enabling further reinforcement at different heights of the support body 1. In actual operation, the movable seats 8 are driven to rise to the corresponding heights sequentially from top to bottom. The bottom surface of the fixed seat 2 is fixedly connected to several support seats 4 arranged in a circular array around the support body 1. The upper surface of the support seat 4 is provided with a groove 5, and the same number of sliders 6 as the movable seats 8 are slidably connected in the groove 5. The sliders 6 in the same groove 5 correspond one-to-one with the movable seats 8 and are used to pull the movable seat 8 at an angle. In this scheme, the sliders 6 of the several support seats 4 arranged in a circular array are distributed at equal distances from the support body 1. Figure 2 and Figure 3 According to the distance from the support body 1, a number of sliders 6 are distributed in a circular pattern from the inside to the outside with the support body 1 as the center. Therefore, the outermost sliders 6 correspond to the uppermost movable seat 8, the innermost sliders 6 correspond to the lowermost movable seat 8, and so on. Each circle of sliders 6 corresponds to a certain layer of movable seat 8. Therefore, it is possible to achieve diagonal support for the movable seat 8, and thus achieve diagonal support for different height areas of the support body 1.
[0025] Additionally: Expansion bolts 11 for connecting to the ground are provided through the corners of the upper surface of the support base 4, and the support base 4 is fixed to the ground by means of the expansion bolts 11; a fixing pin 12 for threaded connection with the inner wall of the slide groove 5 is provided through the side of the slider 6, and the fixing pin 12 is used to fix the slider 6 in a fixed position inside the support base 4 to ensure that the slider 6 will not slide.
[0026] Additionally: A winding wheel 7 is provided on the upper surface of the slider 6. Each movable seat 8 corresponds to one of the winding wheels 7 on any support seat 4. A pull rope 3 is wound on each winding wheel 7, and one end of the pull rope 3 is connected to a sliding seat 10. The sliding seat 10 is installed on the side of the movable seat 8 at the position corresponding to the winding wheel 7. When the movable seat 8 rises, the pull rope 3 is released under the action of the sliding seat 10, simultaneously driving the winding wheel 7 to rotate. After the movable seat 8 rises to the corresponding position, the pull rope 3 is straightened and tightened by rotating the winding wheel 7. The pull rope 3 is used to provide diagonal support for the movable seat 8, i.e. the support body 1. In addition, the reel 7 used in this solution is an existing product, and any model of reel with locking function can be selected from the market. The outer side of the movable seat 8 is fixedly connected to the rail 15, which is set with the same center as the movable seat 8. The sliding seat 10 is inserted into the rail 15 and is connected to the side of the movable seat 8 by a fixing nail 14. The position of the sliding seat 10 can be adjusted by the rail 15, and then the fixing nail 14 is used to fix the sliding seat 10 to the side of the movable seat 8.
[0027] The working principle is as follows: after the support body 1 is constructed, the fixed seat 2 is fixed to the support body 1 using connecting bolts 13. Similarly, the several movable seats 8 above are combined and fixed using connecting bolts 13. One end of the pull rope 3 on the winding wheel 7 is fixed to the sliding seat 10 on the corresponding movable seat 8. Then, according to the order from top to bottom, the corresponding movable seat 8 is raised to the specified height by rotating the corresponding screw 9. After that, the winding wheel 7 is reversed to straighten and tighten the pull rope 3, thereby achieving the diagonal support of the movable seat 8, i.e., the support body 1.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
