Description

Technical Field

[0001] This utility model relates to the field of pillar shoe technology, specifically to a single pillar shoe with adjustable angle. Background Technology

[0002] Before mining underground deposits, the roadways in the mining area are arranged in a reasonable manner. In order to avoid instability of the surrounding rock, it is necessary to use individual props for support. When using individual props, prop shoes are needed to provide auxiliary support for the props.

[0003] However, the orientation and angle of the grooves on the existing single-prop support shoes are fixed, which can only be adapted to flat ground. In actual mining, the coal seam occurrence conditions are complex and varied. The coal seam is not always flat and often presents a slope. At this time, because the orientation of the grooves on the support shoes is fixed, in order to ensure the vertical force and stable support of the single prop, the construction workers have to manually excavate and level the position of the support shoes first. This extra process not only consumes a lot of manpower and time, but also prolongs the preparation cycle of the support operation and affects the work efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an angle-adjustable single-support column shoe to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle-adjustable single-piece support column shoe, including a chassis, an mounting component fixed in the middle of the top of the chassis, and a connecting seat connected to the inner side of the mounting component via a connecting shaft, sliding sleeves fixed on both sides of the top of the chassis, a sliding rod slidably connected inside the sliding sleeve, and wedge blocks fixed at both ends of the sliding rod, a positioning hole opened on one side of the sliding rod, and a positioning bolt extending into the inner side of the positioning hole threadedly connected to one side of the sliding sleeve.

[0006] Furthermore, the connecting seat is provided with a column groove, and a stiffening plate is fixed between the connecting seat and the column groove.

[0007] By adopting the above technical solutions, the stiffening plates can enhance the connection strength, ensure the structural stability between the column groove and the connecting seat, and improve the load-bearing capacity and durability of the overall device.

[0008] Furthermore, a chain is connected to one side of the chassis, and a hook is fixed to one end of the chain.

[0009] By adopting the above technical solution, the iron chain is usually fixed to the support by hooks. During the erection, movement or recycling of the support, the support shoe may separate from the support due to vibration, collision or other reasons. The iron chain can bind the two together, which solves the problem of the support shoe of a single support being easily lost.

[0010] Furthermore, the positioning holes are provided in several groups, and the several groups of positioning holes are distributed at equal intervals.

[0011] By adopting the above technical solution, several sets of equidistantly distributed positioning holes can provide multiple fixed positions for positioning bolts, realize graded adjustment of column groove angle, meet the adaptation requirements of different coal seam dip angles, and the adjustment accuracy is uniform and controllable.

[0012] Furthermore, a slider is fixed to the bottom of the wedge block, and a groove is provided on the top of the chassis, with the wedge block slidingly engaging with the groove via the slider.

[0013] By adopting the above technical solution, the sliding cooperation between the slider and the groove provides guidance for the displacement adjustment of the wedge block, ensuring its smooth and stable movement.

[0014] Furthermore, the bottom of the chassis is provided with several sets of anti-slip teeth, and all the anti-slip teeth are conical.

[0015] By adopting the above technical solution, the anti-slip teeth increase the friction, effectively preventing the device from slipping on slopes and other working conditions, and further improving the overall stability.

[0016] Furthermore, the wedge blocks are provided in two sets, and one side of each set of wedge blocks is sloped.

[0017] By adopting the above technical solution, both sets of wedge blocks have a sloping side. The cooperation of the sloping surfaces allows the other set to smoothly retract when one set is squeezed, providing stable support for the angle adjustment of the connecting seat.

[0018] In summary, this utility model has the following beneficial effects: By incorporating two sets of wedge blocks, positioning bolts, positioning holes, sliding rods, sliding sleeves, connecting shafts, and connecting seats, when dealing with sloping coal seams, workers place the chassis on the coal seam and then adjust the displacement of the two sets of wedge blocks. One set of wedge blocks can compress the bottom of the connecting seat, while the other set of wedge blocks will retract. Simultaneously, the sliding rod slides within the sliding sleeve, causing the connecting seat to change its angle around the connecting shaft. After adjustment, the positioning bolts are screwed into the corresponding positioning holes to complete the fixation. This allows for flexible adjustment of the column groove angle according to changes in the coal seam dip angle, ensuring that the single support column remains vertical during operation, guaranteeing the efficiency and stability of the single support column. It eliminates the tedious process of pre-leveling the coal seam, saving manpower and time costs, and significantly improving the safety and economy of operations in complex coal seam environments.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Example 1: An angle-adjustable single-support column shoe, such as Figures 1-5 As shown, the device includes a chassis 1. A mounting component 2 is fixed to the top center of the chassis 1. The inner side of the mounting component 2 is connected to a connecting seat 4 via a connecting shaft 3. The connecting seat 4 has a column groove 5, and a stiffening plate 16 is fixed between the connecting seat 4 and the column groove 5. The stiffening plate 16 can enhance the connection strength, ensure the structural stability between the column groove 5 and the connecting seat 4, and improve the load-bearing capacity and durability of the overall device. Sliding sleeves 6 are fixed to the top two sides of the chassis 1. A sliding rod 10 is slidably connected inside the sliding sleeve 6, and wedge blocks 9 are fixed to both ends of the sliding rod 10. A positioning hole 15 is opened on one side of the sliding rod 10, and a positioning bolt 13 extending to the inner side of the positioning hole 15 is threadedly connected to one side of the sliding sleeve 6.

[0024] See Figure 1 In the above embodiment, a chain 11 is connected to one side of the chassis 1, and a hook 12 is fixed to one end of the chain 11. The chain is usually fixed to the support through the hook 12. During the erection, movement or recycling of the support, the support shoe may separate from the support due to vibration, collision or other reasons. The chain can bind the two together, which solves the problem that the support shoe of a single support is easy to lose.

[0025] See Figure 1 and Figure 4In the above embodiment, the positioning holes 15 are provided in several groups, and the several groups of positioning holes 15 are equidistantly distributed. The several groups of equidistantly distributed positioning holes 15 can provide multiple fixed positions for the positioning bolts 13, realize the graded adjustment of the column groove 5 angle, meet the adaptation requirements of different coal seam dip angles, and the adjustment accuracy is uniform and controllable.

[0026] See Figures 1-2 In the above embodiment, the bottom of the chassis 1 is provided with several sets of anti-slip teeth 14, and the anti-slip teeth 14 are all conical. The anti-slip teeth 14 increase the friction and effectively prevent the device from slipping on slopes and other working conditions, thereby further improving the overall stability.

[0027] See Figure 1 , Figure 2 and Figure 4 In the above embodiment, the wedge block 9 is provided in two sets, and one side of each set of wedge blocks 9 is sloping. The slope surfaces cooperate with each other, so that when one set is squeezed, the other set can smoothly retreat, providing stable support for the angle adjustment of the connecting seat 4.

[0028] Example 2: To make the wedge block displacement more stable, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 , Figure 4 and Figure 5 The bottom of the wedge block 9 is fixed with a slider 8, and the top of the chassis 1 is provided with a sliding groove 7. The wedge block 9 slides with the slider 8 and the sliding groove 7. The sliding cooperation between the slider 8 and the sliding groove 7 provides guidance for the displacement adjustment of the wedge block 9, ensuring that its movement is smooth and stable.

[0029] The implementation principle of this utility model is as follows: First, the device is placed and the chain 11 is fixed. The worker places the chassis 1 stably in the predetermined position of the sloping coal seam. At this time, the conical anti-slip teeth 14 at the bottom of the chassis 1 are embedded in the coal seam to prevent the chassis 1 from sliding. At the same time, the chain 11 is fixed to the single support through the hook 12 to prevent the support shoe from separating or shifting due to movement or collision in subsequent operations. Next, the wedge blocks 9 are adjusted. According to the actual dip angle of the coal seam, the workers push the two sets of wedge blocks 9 so that the wedge blocks 9 slide in the groove 7 at the top of the chassis 1 through the bottom slider 8. Since one side of both sets of wedge blocks 9 is sloping, during the sliding process, one set of wedge blocks 9 will squeeze the bottom of the connecting seat 4, while the other set of wedge blocks 9 will move back accordingly. At the same time, the slide rod 10 slides synchronously inside the sliding sleeve 6, driving the connecting seat 4 to rotate around the connecting shaft 3, thereby adjusting the angle of the column groove 5 on the connecting seat 4. Then, fix the angle. When the angle of the column groove 5 is adjusted to make the single support column vertical, the staff stops adjusting the wedge block 9 and screws the positioning bolt 13 from one side of the sliding sleeve 6 into the corresponding positioning hole 15 on the sliding rod 10. Through the cooperation of the positioning bolt 13 and the positioning hole 15, the position of the wedge block 9 is fixed, thereby locking the angle of the column groove 5.
