Description

Technical Field

[0001] This invention relates to the field of downhole sealing technology, specifically a sealing device for downhole tunnel filling. Background Technology

[0002] In recent years, with the continuous development of coal resources, more and more old mines are facing resource depletion and the urgent situation of mine closure. Therefore, backfilling technology to solve this problem has developed rapidly. In order to ensure that the backfill can be properly connected to the roof and completely replace the remaining coal pillar, a simple and reliable sealing device is needed to seal the entrance of the backfilling roadway during backfilling. The existing sealing method usually uses scaffolding steel pipes + wooden boards + nylon woven bags. This method has disadvantages such as high labor intensity for workers, large personnel occupation, long erection time, low reliability, large material loss, and long recovery and dismantling time, which affects the backfilling efficiency; and it cannot achieve effective monitoring, resulting in low safety.

[0016] Example: Please refer to Figure 1-10 In this embodiment of the invention, a sealing and plugging device for underground tunnel filling is provided, comprising: Floor plate 1, which is detachably fixed to the roadway floor plate; Multiple vertically connected lower sealing components 2; The upper sealing assembly 3 is connected to the uppermost lower sealing assembly 2; and Monitoring and reinforcement components 5 are configured on the lower sealing component 2 and / or the upper sealing component 3; Since both the lower sealing component 2 and the upper sealing component 3 are mounted on the base plate 1, and the base plate 1 is detachably fixed to the roadway floor, the device can be quickly disassembled and removed after use, meaning that the device can be reused multiple times. in addition, Figure 1The image only shows a portion of the monitoring and reinforcement components 5 provided on the lower sealing assembly 2 and / or the upper sealing assembly 3; Of course, adjustments can be made during actual construction. For example, detection and reinforcement components 5 can be set for stress concentration areas, or even multiple detection and reinforcement components 5 can be set in stress concentration areas. In this embodiment, the monitoring and reinforcement component 5 is movable and has at least a monitoring end and a reinforcement end. Therefore, in practice, mobile monitoring can be achieved using the monitoring and reinforcement component 5. The monitoring end is used to monitor the deformation of the lower sealing component 2 and / or the upper sealing component 3, and when the deformation exceeds a first threshold, the reinforcement end reinforces the part.

[0017] Specifically, the monitoring and reinforcement component 5 includes: The movable seat 52 is movably disposed on the lower sealing assembly 2 and / or the upper sealing assembly 3; The movable plate 51 is fixed on the movable base 52; Telescopic cylinder 55 is fixedly embedded in the movable plate 51; Reinforcing component 53, which serves as the reinforcing end and is fixed to the output end of the telescopic cylinder 55; and The displacement sensor 54 is fixedly embedded in the movable plate 51 as the monitoring end, and the input end of the displacement sensor 54 is connected to the reinforcement component 53. The reinforcement component 53 is also embedded with a pressure sensor. When the monitoring reinforcement component 53 is used for monitoring, when the pressure sensor detects that the pressure is greater than the pressure threshold, the telescopic cylinder 55 will retract. At this time, the displacement sensor 54 records the displacement of the reinforcement component 53, that is, at this time the displacement sensor 54 records the deformation of the lower sealing component 2 and / or the upper sealing component 3.

[0018] Additionally, the reinforcement component 53 includes: Connecting seat 531, which is fixed to the output end of the telescopic cylinder 55; Four circumferentially distributed rotating arms 532 are rotatably mounted on the connecting seat 531 and can make way for each other to achieve aggregation or dispersion. The first reinforcing head 533 is fixed to the rotating arm 532; and A second reinforcing head 534 is fixed to the middle of the connecting seat 531.

[0019] Based on this, the reinforcement component 53 also includes a microcontroller for controlling the rotating arm 532. The microcontroller is configured to: when the displacement sensor 54 detects that the deformation of the lower sealing component 2 and / or the upper sealing component 3 is greater than a first threshold and less than a second threshold, control the reinforcement component 53 to reinforce the part in an aggregated manner; when the displacement sensor 54 detects that the deformation of the lower sealing component 2 and / or the upper sealing component 3 is greater than the second threshold, control the reinforcement component 53 to reinforce the part in a dispersed manner.

[0020] It should be explained that, in the initial state, the reinforcing components 53 are clustered together, which provides better throughput. When the displacement sensor 54 detects that the deformation of the lower sealing component 2 and / or the upper sealing component 3 is greater than a first threshold but less than a second threshold, the reinforcing components 53 are controlled to remain clustered together to reinforce that part. When the displacement sensor 54 detects that the deformation of the lower sealing component 2 and / or the upper sealing component 3 is greater than the second threshold, the reinforcing components 53 are controlled to be dispersed to reinforce that part, thereby achieving large-area reinforcement of the lower plate 8 or the upper plate 9 and ensuring its overall strength. like Figure 10 The rotating arm 532 includes a first end 5321 and a second end 5322. There is a first clearance space a below the first end 5321 and a second clearance space b above the second end 5322. The first clearance space a can accommodate the second end of another rotating arm (which also has a second clearance space b above its second end).

[0021] In this embodiment, both the lower sealing component 2 and the upper sealing component 3 include: Connector 7; and Multiple lower plates 8 and upper plates 9 are connected to one side of the connecting frame 7. The multiple lower plates 8 and multiple upper plates 9 are arranged in a horizontally adjacent array, and the lower plates 8 and upper plates 9 are in close contact with each other. The two adjacent lower sealing components 2 are connected by a connecting frame 7, and the uppermost lower sealing component 2 is connected to the upper sealing component 3. The movable seat 52 is movably mounted on the connecting frame 7.

[0022] It is worth mentioning that in this embodiment, multiple lower plates 8 and upper plates 9 can be connected by configuring the connecting frame 7, and the connecting frame 7 can also serve as the moving track of the monitoring and reinforcement component 5; More specifically, the connecting frame 7 has multiple connecting holes, while the lower plate 8 and upper plate 9 each have multiple through holes 10 corresponding to the connecting holes. During installation, the bolt passes through the lower plate 8 and the connecting frame 7 in sequence to connect with the nut, which is housed in the connecting frame 7; or, the bolt passes through the upper plate 9 and the connecting frame 7 in sequence to connect with the nut, which is housed in the connecting frame 7. Although the nut is located in the connecting frame 7, it does not interfere with the movable seat 52 because the connecting frame 7 includes: Vertical plate 71, which is detachably connected to the lower plate 8 and the upper plate 9 by bolts; Horizontal plates 72 are connected to both ends of the vertical plate 71; A rear support plate 73 and a front support plate 74 are connected to one side of the horizontal plate 72. The front support plate 74 is hook-shaped. The horizontal plate, the front and rear support plates 73, and the front support plate 74 form a limiting sliding space for sliding connection of the movable seat 52.

[0023] That is, the movable seat 52 is slidably disposed in the sliding space, while the nut is located on one side of the sliding space; In addition, when the monitoring and reinforcement component 5 is used to support and reinforce the upper plate 8 and the lower plate 9, the reaction force generated during reinforcement will be concentrated on the front support plate 74. In this embodiment, the front support plate 74 is configured as a hook, which can improve the overall strength. In this embodiment, both the lower plate 8 and the upper plate 9 located at the edge are provided with side hinge grooves 11. A side hinge plate 12 is hinged in the side hinge groove 11 by a side hinge shaft. A side return spring is connected between the side hinge shaft and the side hinge groove 11.

[0024] The side return spring is a high-strength return spring. In the initial state, the side hinge plate 12 is flush with the lower plate 8 and the upper plate 9. During implementation, in order to adapt to the side length of the roadway, the side hinge plate 12 may deflect. The upper plate 9 of the upper sealing assembly 3 is provided with an upper hinge groove 13. An upper hinge plate 14 is hinged in the upper hinge groove 13 by an upper hinge shaft. An upper return spring is connected between the upper hinge shaft and the upper hinge groove 13. Similarly, the upper return spring is a high-strength return spring. In the initial state, the upper hinge plate 14 is flush with the lower plate 8 and the upper plate 9. During implementation, in order to adapt to the height of the tunnel, the upper hinge plate 14 may deflect. In this embodiment, a reinforcing plate 75 is fixed on the upper horizontal plate 72. The reinforcing plate 75 has multiple threaded holes for threaded connection to the support plate 6. The support plate 6 is supported on the base plate 1. The support plate 6 includes: Horizontal plate 61; and Inclined plate 62 fixed to the horizontal plate 61; One end of the horizontal plate 61 is connected to a screw, which is threaded into a threaded hole. The length of the other end of the horizontal plate satisfies the condition that there is no interference between the inclined plate 62 and the monitoring and reinforcement component 5.

[0025] In other words, the connecting frame 7 can not only connect the lower plate and the upper plate, serving as a guide rail for the detection and reinforcement component 5, but also connect the support plate 6, thereby providing better support for the connecting frame 7 through the support plate 6. In this embodiment, the movable seat 52 includes: The base 521 is slidably disposed in the sliding space, and a power wheel 522 is rotatably disposed on the upper part of the base 521. The power wheel 522 has rotational power, which will not be described in detail here. The lower part of the base 521 is rotatably provided with two symmetrically arranged support wheels 523; and An extension seat 524 is fixed to the base 521, extends out of the sliding space, and is connected to the movable plate 51.

[0026] During implementation, multiple intermittent filling operations are required to ensure the effectiveness of the roof connection. Therefore, the lower sealing component 2 is first built layer by layer. After each layer of lower sealing component 2 is built, grouting is performed until the filling material to be solidified reaches or is about to reach the top of the layer. Then the next layer of lower sealing component 2 is built, and so on. Finally, the upper sealing component 3 is built. At the same time, the spaces in the upper left and upper right corners are sealed with movable wooden boards, but the positions of the filling pipe and the vent pipe must be left. After the assembly is completed, the filling operation can begin, and the roof connection of the filling material in the tunnel is finally completed.

[0027] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
