Description

Technical Field

[0001] The utility model relates to the technical field of coal mine supports, in particular to a coal mine anti-collapse support. Background Art

[0002] The existing supporting anti-collapse supports mainly include hydraulic rods and supporting frames, which use the hydraulic rods and the side frames to support the tunnel. However, the existing devices have certain disadvantages. For example, the announcement No. CN221742633U records a coal mine anti-collapse support, which includes a base, a pile pipe is installed on the top of the base, a support pipe is vertically slidably installed in the pile pipe, a support plate is installed on the top of the support pipe, a hydraulic cylinder located in the support pipe is installed on the base, a lifting block that slides with the inner wall of the support pipe is fixed on the top of the hydraulic cylinder, a mounting groove is opened on the top of the lifting block, a lifting assembly is fixed in the mounting groove, a lifting plate is fixed in the support pipe, and the bottom end of the lifting plate conflicts with the top of the lifting end of the lifting assembly;

[0003] Although the above device can be raised without using a hydraulic pump, the support area of ​​the bracket is not adjusted after the ground sinks or rises, resulting in the bracket itself being not stable enough and it being inconvenient to combine the brackets for use, resulting in the bracket being not flexible enough when used. Utility Model Content

[0004] The purpose of the utility model is to provide a coal mining anti-collapse support to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A coal mine anti-collapse support, comprising a column, an extension frame slidably connected to the outer surface of the column, a mounting plate fixedly connected to the outer surface of the column, a jack fixedly connected to the upper surface of the mounting plate, and an interference frame detachably connected to the outer surface of the extension frame;

[0007] The two side surfaces of the column are fixedly connected with sliding rails, and the outer surfaces of the sliding rails are slidably connected with sliding support modules.

[0008] Furthermore, the front surface and the rear surface of the column are both provided with limiting grooves, the extension frame and the limiting grooves are slidably connected, and the upper surface of the column is provided with a base hole.

[0009] Furthermore, the front surface and the rear surface of the interference frame are both threadedly connected with connecting bolts, and the interference frame is detachably connected to the extension frame through the connecting bolts.

[0010] Furthermore, countersunk holes are provided on the lower surface of the interference frame and at positions corresponding to the jack, and the output end of the jack is inserted into the countersunk holes.

[0011] Furthermore, the sliding support module also includes a slider, a mounting block, a fixing frame, a lifting rod and a hinged seat. The slider is slidably connected to the outer surface of the sliding rail, the mounting block is detachably connected to the upper surface of the slider, the upper surface of the mounting block is threadedly connected to two bolts, the fixing frame is fixedly connected to the upper surface of the slider, the upper surface of the fixing frame is embedded with a threaded column rotatably connected, the upper end of the threaded column is fixedly connected to a handwheel, the lifting rod is embedded in the upper surface of the slider, the lifting rod and the threaded column are threadedly connected, the hinged seat is rotatably connected to the end of the lifting rod, and a through hole is opened on the upper surface of the hinged seat.

[0012] Furthermore, a sliding groove is provided on the upper surface of the sliding rail, and the number of the sliding rails is two.

[0013] Furthermore, the upper surface of the extension frame is provided with connection holes near the four corners.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Since the interference frame and the extension frame are connected together by a threaded assembly, the position of the extension frame can be changed by adjusting the support height of the jack through an external crank. This is suitable for when the mounting device partially sinks during bracket installation. The length of this bracket can also be adjusted to improve the flexibility of the device.

[0016] 2. Rotate the threaded column by the hand wheel. The lifting rod rises or falls under the push of the thread. Then use the external threaded components to match the through hole to fix the hinge seat and the ground together. Since there are two sliding support modules, when the angle between one hinge seat and the ground changes, the other hinge seat applies tension to the bracket to increase the stability of the bracket. When multiple brackets are used in combination, such as Figure 1 As shown, the sliding support modules between multiple brackets are connected together by threaded components, so that adjacent columns form a whole, and the bracket is used as a guardrail, thereby increasing the stability of the bracket and making the bracket more flexible when used.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 In an embodiment of the utility model, a coal mine anti-collapse support includes a column 1, an outer surface of the column 1 is slidably connected to an extension frame 6, an outer surface of the column 1 is fixedly connected to a mounting plate 103, an upper surface of the mounting plate 103 is fixedly connected to a jack 3, and an outer surface of the extension frame 6 is detachably connected to a resistance frame 2;

[0024] Sliding rails 4 are fixedly connected to both side surfaces of the column 1 , and sliding support modules 5 are slidably connected to the outer surfaces of the sliding rails 4 .

[0025] Specifically, when in use, the jack 3 is started, and the jack 3 cooperates with the interference frame 2 to lift the extension frame 6, so that the extension frame 6 cooperates with the column 1 to support the position of the coal mine tunnel. Since the extension frame 6 and the column 1 are adjustable, when the installation device partially sinks, the length of the bracket can also be adjusted to improve the flexibility of the device. After the device is installed, the position and shape of the sliding support module 5 can be adjusted to increase the ground contact area and improve the stability of the bracket when used alone. Multiple brackets can also be used simultaneously to connect other brackets to form a protective fence, thereby improving the practicality of the device.

[0026] Example 1

[0027] like Figure 1-4 As shown, the front surface and the rear surface of the column 1 are both provided with limiting grooves 101 , the extension frame 6 is slidably connected to the limiting grooves 101 , and the upper surface of the column 1 is provided with a base hole 102 .

[0028] In this embodiment, the limiting groove 101 limits the extension frame 6 so that the extension frame 6 can slide inside the limiting groove 101, and the base hole 102 is used to cooperate with an external fixing component to fix the bracket inside the coal mine.

[0029] like Figure 1-4 As shown, the front and rear surfaces of the resistance frame 2 are both threadedly connected with connecting bolts 201, and the resistance frame 2 is detachably connected to the extension frame 6 through the connecting bolts 201. Countersunk holes are provided on the lower surface of the resistance frame 2 and at corresponding positions of the jack 3, and the output end of the jack 3 is inserted into the interior of the countersunk hole.

[0030] In this embodiment, the output end of the jack 3 is connected to the countersunk hole and the resistance frame 2, and the output end of the jack 3 and the resistance frame 2 can also be directly connected together by welding. Since the resistance frame 2 and the extension frame 6 are fixed together by a threaded assembly, the position of the extension frame 6 can be changed by adjusting the support height of the jack 3 through an external crank. It is suitable for the case where the installation device partially sinks during the installation of the bracket. The bracket can also be adjusted in length to improve the flexibility of the device.

[0031] Example 2

[0032] On the basis of the first embodiment, in order to make up for the problem in the first embodiment that it is inconvenient to adjust the support surface.

[0033] like Figure 1-4 As shown, the sliding support module 5 also includes a slider 501, a mounting block 502, a fixed frame 503, a lifting rod 506 and a hinge seat 507. The slider 501 is slidably connected to the outer surface of the sliding rail 4, the mounting block 502 is detachably connected to the upper surface of the slider 501, the upper surface of the mounting block 502 is threadedly connected to two bolts, the fixing frame 503 is fixedly connected to the upper surface of the slider 501, the upper surface of the fixing frame 503 is embedded with a threaded column 504 for rotation connection, the upper end of the threaded column 504 is fixedly connected to a handwheel 505, the lifting rod 506 is embedded in the upper surface of the slider 501 for sliding connection, the lifting rod 506 and the threaded column 504 are threadedly connected, the hinge seat 507 is rotatably connected to the end of the lifting rod 506, and a through hole 508 is provided on the upper surface of the hinge seat 507.

[0034] In this embodiment, the position of the sliding support module 5 can be adjusted by sliding the slider 501 along the sliding rail 4. After the adjustment, the threaded column 504 is rotated by the hand wheel 505. Under the push of the thread, the lifting rod 506 rises or falls, and then the external threaded component is used to cooperate with the through hole 508 to fix the hinge seat 507 and the ground together. Since there are two sliding support modules 5, when the angle between one of the hinge seats 507 and the ground changes, the other hinge seat 507 applies tension to the bracket to increase the stability of the bracket. When multiple brackets are used in combination, such as Figure 1 As shown, the sliding support modules 5 between multiple brackets are connected together by threaded components, so that adjacent columns 1 form a whole, and the bracket is used as a guardrail, thereby increasing the stability of the bracket and making the bracket more flexible when used.

[0035] like Figure 1-4 As shown, a sliding groove 401 is provided on the upper surface of the sliding rail 4 , there are two sliding rails 4 , and connection holes 601 are provided on the upper surface of the extension frame 6 near the four corners.

[0036] In this embodiment, the slider 501 is slidably connected with the mounting block 502 and the sliding groove 401, and the connecting hole (601) can be used to cooperate with the threaded assembly to install the external transverse plate, and the support area of ​​the extension frame (6) can be increased by the transverse plate.
