[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0030] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0031] Combination Figures 1-7As shown in the figure, a portable coal mine underground column quick-assembly and disassembly device in this embodiment includes a connecting component and a fixing component. The connecting component is used to realize the mutual docking between two columns, which respectively form an upper column 100 and a lower column 101. An annular groove 601 is provided on the outer side wall of the upper column 100 along its circumference. The connecting component includes a slidable connecting cylinder 104 disposed in the annular groove 601, and the connecting cylinder 104 is threadedly installed on the lower column 101. The upper column 100 is also provided with a lifting component for lifting the connecting cylinder 104. The fixing component is used to realize the lifting and lowering adjustment of the lower column 101.

[0032] In actual use, the upper end of the upper column 100 is connected to the top plate 102 via a flange 200. The top plate 102 is fixed to the top wall of the tunnel with expansion bolts, so that the top plate 102 can be installed, and thus the upper column 100 can be installed. At this time, by translating the lower column 101 and adjusting the lower column 101 by means of the fixing component, the upper end of the lower column 101 is brought into contact with the lower end of the upper column 100. By means of the connecting component, the connecting cylinder 104 can be threadedly connected to the upper end of the lower column 101, so that the upper column 100 and the lower column 101 can be installed together. At this time, by means of the fixing component, the fixing component can fix the lower end of the lower column 101 to the ground of the tunnel, so that the column can better support and fix the tunnel.

[0033] In order to facilitate the operator to move the lower column 101 horizontally, in this embodiment, a handle 105 is provided on the outer side wall of the lower column 101. The handle 105 facilitates the operator to move the lower column 101 horizontally.

[0034] In actual use, when the connecting cylinder 104 slides to the bottom wall of the annular groove 601, the lower end of the upper column 100 is located inside the connecting cylinder 104. In order to prevent the lower column 101 from being unable to move horizontally, its upper end is attached to the lower end of the upper column 100. Through the setting of the lifting component, the lifting component can lift the connecting cylinder 104, so that the lower end of the upper column 100 can be exposed, thereby making it easier for the operator to move the lower column 101 horizontally, so that its upper end can be attached to the lower end of the upper column 100, so that the connecting cylinder 104 can be connected and installed with the upper column 100 and the lower column 101.

[0035] The annular groove 601 has a lower end with a stop block 203. A threaded post 204 is located on the upper side wall of the stop block 203 at the center. The upper post 100 has a threaded hole with an opening at the lower end. By rotating the stop block 203, the threaded post 204 is loosened, allowing the threaded post 204 to disengage from the threaded hole, thus opening the annular groove 601. At this time, the connecting cylinder 104 is moved upward and slid into the annular groove 601, and is hoisted by a hoisting device to fix the connecting cylinder 104. Then, the threaded post 204 is threaded into the threaded hole, closing the annular groove 601, so that the connecting cylinder 104 can be slidably installed in the annular groove 601.

[0036] The connection components allow the columns to be installed by docking, and the columns can be segmented, making it easier for operators to transport the columns into the tunnel and install them there.

[0037] Combination Figure 7 As shown, in this embodiment, the fixing component includes a mounting plate 107. The upper side wall of the mounting plate 107 is provided with a mounting base 106. The mounting base 106 is provided with a slot for the lower column 101 to be inserted. The side wall of the mounting base 106 is provided with a plurality of positioning holes 108 that communicate with the slots. The lower column 101 is provided with an insertion hole that matches the positioning hole 108 at its lower position. The positioning hole 108 is provided with a positioning shaft 109 for insertion into the insertion hole.

[0038] In actual use, the lower column 101 is inserted into the slot and the positioning shaft 109 is inserted into the corresponding positioning hole 108, so that the lower column 101 can be installed on the mounting base 106. When the lower end of the upper column 100 is in contact with the upper end of the lower column 101, the mounting plate 107 is fixed to the ground of the tunnel by the expansion bolts, so that the column can be fixed and thus the column can better support the tunnel.

[0039] In actual use, when the column needs to be disassembled, the expansion bolts fixing the top plate 102 are released. Then, the positioning holes 108 and positioning shaft 109 are set so that the positioning shaft 109 can be pulled outward and disengaged from the corresponding positioning hole 108. This allows the lower end of the lower column 101 to slide onto the bottom wall of the slot due to its own weight, creating a gap between the top plate 102 and the top wall of the tunnel. Then, the connecting cylinder 104 is rotated to release the connection between the upper column 100 and the lower column 101, allowing the upper column 100 to tilt through the gap. This allows the operator to tilt and remove the upper column 100, facilitating actual operation.

[0040] In this embodiment, a handle is provided at one end of the positioning shaft 109 to facilitate the operator to pull the positioning shaft 109 outward.

[0041] Combination Figures 3-5 As shown, an installation groove 600 is provided on the outer wall of the upper column 100 above the annular groove 601, and the installation groove 600 is arranged around the circumference of the upper column 100; the lifting component includes an installation ring 103 disposed in the installation groove 600, a sliding rod 201 disposed opposite to the installation ring 103, the sliding rod 201 is arranged perpendicular to the installation ring 103, an installation block 303 is provided at the lower end of the sliding rod 201, a nut 301 is provided at the upper end of the sliding rod 201, and a first spring 302 for pushing the sliding rod 201 is sleeved on the sliding rod 201; a cavity 202 is provided inside the connecting cylinder 104, and a notch 500 is provided on the upper side wall of the connecting cylinder 104 that communicates with the cavity 202 and is adapted to the installation block 303.

[0042] In actual use, the cavity 202 is circular. The connecting cylinder 104 is moved upward and rotated so that the notch 500 can be aligned with the mounting block 303. At this time, the sliding rod 201 is pressed down so that the sliding rod 201 can drive the mounting block 303 to move downward and enter the cavity 202 through the notch 500. At this time, the sliding rod 201 is rotated so that the sliding rod 201 can drive the mounting block 303 to rotate and misalign with the notch 500. At this time, the sliding rod 201 is stopped from being pressed down so that the first spring 302 can push the nut 301 to drive the sliding rod 201 to move upward, so that the mounting block 303 can be tightly attached to the upper side wall of the cavity 202, thereby allowing the connecting cylinder 104 to be hoisted.

[0043] In actual use, when the connecting cylinder 104 needs to be threaded to the upper column 100, the rotating slide rod 201 drives the mounting block 303 to rotate. When the mounting block 303 is aligned with the notch 500, the connecting cylinder 104 moves down and detaches from the lifting component due to its own weight.

[0044] Combination Figures 2-3 As shown, in this embodiment, the mounting ring 103 is composed of two interlocking mounting half-rings 300. One end of each mounting half-ring 300 is provided with a rotating plate 304 facing each other, and a fixing post 305 is provided between the opposing rotating plates 304. The two mounting half-rings 300 are rotatably mounted on the corresponding fixing post 305. The other end of each mounting half-ring 300 is provided with a locking member, which is used to realize the mounting ring 103 in the annular groove 601 for assembly and disassembly.

[0045] In practical use, the locking mechanism allows the mounting ring 103 to be installed and removed within the mounting groove 600. When the connecting cylinder 104 completes the docking installation between the upper column 100 and the lower column 101, the locking mechanism releases the mounting ring 103 from the upper column 100, allowing it to be removed. The rotation of the two mounting half-rings 300 allows them to engage with the mounting groove 600 of another upper column 100 and be secured by the locking mechanism, thus enabling the mounting ring 103 to be installed on the other upper column 100, allowing the lifting component to be reused.

[0046] Combination Figures 4-5 As shown, in this embodiment, the locking member includes a locking plate 307 disposed on one of the mounting half-rings 300, the locking plate 307 having a locking hole. The locking member also includes a locking block 306 disposed on the other mounting half-ring 300, the locking block 306 having a locking cavity 402, the locking cavity 402 having a slidable locking rod 400, the upper end of the locking rod 400 extending through the locking cavity 402, the locking rod 400 located in the locking cavity 402 having an abutment plate 403, the locking rod 400 located in the locking cavity 402 having a second spring 401 sleeved on it for pushing the locking rod 400 downward, the locking rod 400 being inserted into the locking hole to achieve closure between the mounting half-rings 300.

[0047] In actual use, the side wall of the locking block 306 is provided with a slot 308 that communicates with the locking cavity 402. The slot 308 is used for the locking plate 307 to be inserted into the locking cavity 402. The side wall of the locking plate 307 is provided with a first inclined surface, and the lower end of the locking rod 400 is provided with a second inclined surface that matches the first inclined surface.

[0048] In actual use, by rotating one of the mounting half-rings 300, the mounting half-ring 300 can drive the locking plate 307 to rotate, so that the locking plate 307 can be inserted into the locking cavity 402 through the slot 308, so that the first inclined surface can fit with the second inclined surface. At this time, by continuing to rotate one of the mounting half-rings 300, the first inclined surface can slide and press the second inclined surface, which in turn can drive the locking rod 400 to move upward and compress the second spring 401. When the lock hole and the locking rod 400 are aligned, under the action of the second spring 401, the second spring 401 pushes the abutment plate 403 to drive the locking rod 400 to move downward and insert into the lock hole, so that the locking plate 307 cannot be disengaged from the locking cavity 402, so that the two mounting half-rings 300 can be closed, thereby allowing the mounting ring 103 to be installed in the mounting groove 600.

[0049] Among them, a limiting groove is formed on the outer side wall of the locking rod 400 along its axial direction, and a limiting block is provided on the side wall of the locking block 306, which slides into the limiting groove. By setting the limiting groove and the limiting block, the locking rod 400 cannot rotate in the locking cavity 402, so that the second inclined surface can fit better with the first inclined surface.

[0050] When the operator lifts the locking rod 400, the locking rod 400 can drive the abutment plate 403 to move upward and compress the second spring 401, so that the lower end of the locking rod 400 can disengage from the lock hole, thereby releasing the locking rod 400 from locking the locking plate 307, and thus releasing the installation ring 103 in the installation groove 600.

[0051] Specifically, a pull post 309 is provided at the upper end of the locking rod 400, which makes it easier for the operator to lift the locking rod 400.

[0052] In actual use, the operator fixes the top plate 102 to the upper end of the upper column 100 using the flange 200. Then, the top plate 102 is fixed to the top wall of the tunnel using expansion bolts. Next, the lower column 101 is moved horizontally so that the upper end of the lower column 101 fits against the lower end of the upper column 100. At this time, the connecting cylinder 104 is released by the lifting device, so that the connecting cylinder 104 can slide along the annular groove 601. The connecting cylinder 104 is rotated so that it can be threadedly connected to the upper end of the lower column 101, so that the upper column 100 can be connected to the lower column 101. Finally, the mounting plate 107 is fixed to the ground of the tunnel using expansion bolts, so that the column can better support and fix the tunnel.

[0053] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
