Technical Field

[0002] A mine is a general term for shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Mine development has a significant and far-reaching impact on the overall production and construction of metal mines or coal mines. Before underground construction in a mine, support devices are required to support the inner wall of the mine in order to improve overall safety performance.

[0003] According to a coal mine underground support device disclosed in Chinese Patent Publication No. CN219390847U, the patent sets a laser lamp and a test hole, and can sound an alarm when the light emitted by the laser lamp cannot pass through the test hole to reach the monitoring device, thereby realizing the deformation monitoring function, which is very practical. However, in actual applications, the patent still has certain shortcomings. After the support device is deformed, it is usually repaired and reinforced instead of being scrapped directly. The test plate and the test hole in the patent are fixed to the inner wall of the arched top plate, resulting in the change of the position of the test plate and the test hole after the arched top plate is deformed. After maintenance, renovation and reinforcement, the position of the test hole cannot be conveniently adjusted to a position that is convenient for light to pass through, resulting in low overall applicability and room for improvement in practical performance. In this regard, the present application provides a mine underground support deformation monitoring device to solve the above problems. Utility Model Content

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] See also Figures 1 to 4 The present application provides a technical solution: a mine underground support deformation monitoring device, comprising two main pillars 1, a top guard plate 2 is fixedly installed between the tops of the two main pillars 1, a monitoring mechanism 300 for monitoring deformation is installed between the opposite sides of the two main pillars 1, and a supporting component for support is installed at the bottom end of the main pillar 1; by using the monitoring mechanism 300 between the opposite sides of the two main pillars 1, the position of the test hole can be conveniently adjusted after maintenance, repair and reinforcement of the deformed support structure to facilitate continued monitoring work, thereby improving the adaptability of the overall structure, enabling it to be well adapted to the use of the underground support structure, allowing related work underground in the mine to be carried out safely, and also greatly improving the practicality of the underground support deformation monitoring device.

[0032] In this embodiment, the monitoring mechanism 300 is a structure for monitoring deformation of the supporting structure.

[0033] like Figure 1 As shown, the monitoring mechanism 300 includes a monitoring component installed between opposite sides of two main pillars 1 and an adjusting component installed at the bottom of the roof guard plate 2.

[0034] It should be noted that the adjustment component is used to perform adjustments after deformation occurs so that the monitoring component can continue to perform monitoring work.

[0035] In this embodiment, the adjustment component is a structure used for position adjustment so that the monitoring work can be carried out normally.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, the adjustment assembly includes a plurality of fixed cylinders 306 fixed to the bottom of the top guard plate 2, a connecting rod 307 slidably connected to the inner side of the fixed cylinder 306, a plurality of first locking screws 308 passed through and threadedly connected to the outer side of the fixed cylinder 306, a ball joint 309 fixedly installed on the end of the connecting rod 307 away from the top guard plate 2, a plurality of second locking screws 310 passed through and threadedly connected to the outer side of the ball joint 309, a monitoring plate 311 hinged to the end of the connecting rod 307 away from the top guard plate 2 through the ball joint 309, and a monitoring hole 312 opened on the left side of the monitoring plate 311.

[0037] It should be noted that the lengths of the fixed tubes 306 are different. Taking the middle of the roof guard plate 2 as the dividing line, the lengths of the fixed tubes 306 on the left and right sides decrease successively, and the ends of the fixed tubes 306 away from the roof guard plate 2 are both located in the same horizontal plane. The side of the fixed tube 306 away from the roof guard plate 2 is open, so that the connecting rod 307 can be normally moved out from the inside of the fixed tube 306.

[0038] It should also be noted that two first locking screws 308 are penetrated and threadedly connected to the outside of each fixing tube 306, and the ends of the first locking screws 308 abut against the outside of the corresponding connecting rod 307, so that the first locking screws 308 can abut and limit the connecting rod 307.

[0039] In addition, the ball joint 309 includes a spherical block fixed to the end of the connecting rod 307 away from the top guard plate 2, a connecting seat fixed to the top of the monitoring board 311, and a spherical cavity opened inside the connecting seat for the corresponding spherical block to be placed and moved; the spherical cavity is open on the side away from the monitoring board 311, and two-thirds of the outer side of the spherical block are located on the inner side of the spherical cavity. The outer side of the spherical block fits with the inner side of the corresponding spherical cavity, so that the monitoring board 311 can be movably connected with the connecting rod 307 under the action of the ball joint 309, allowing the monitoring board 311 to move within a certain range.

[0040] At the same time, two second locking screws 310 are penetrated and threadedly connected to the outside of each ball joint 309, and the ends of the second locking screws 310 abut against the outside of the corresponding spherical block, so that the spherical block can achieve the positioning function through the abutment and limiting action of the second locking screws 310.

[0041] In this embodiment, the monitoring component is a structure used to monitor the deformation of the support.

[0042] like Figure 1As shown, the monitoring component includes an adapter power supply 301 fixedly installed on the left main pillar 1 near the right main pillar 1, an audible and visual alarm 302 fixedly installed on the top of the adapter power supply 301, a laser sensor 303 fixedly installed on the left main pillar 1 near the right main pillar 1, a monitor 304 fixedly installed on the right main pillar 1 near the left main pillar 1, and a laser receiving plate 305 fixedly installed on the monitor 304 near the left main pillar 1.

[0043] It should be noted that the position of the laser sensor 303 corresponds to the position of the laser receiving plate 305, the monitoring plate 311 is located between the laser sensor 303 and the opposite side of the laser receiving plate 305, and the monitoring hole 312 is allowed to allow the laser beam emitted by the laser sensor 303 to pass through, so that the laser beam emitted by the laser sensor 303 can pass through the monitoring hole 312 in turn and be received by the laser receiving plate 305.

[0044] In this embodiment, the support assembly is a structure used to provide auxiliary support to the main pillar 1.

[0045] like Figure 1 As shown, the support assembly includes a bottom plate 401 fixed to the bottom end of the main support 1 , and a plurality of stretch rods 402 fixed between the outer side of the main support 1 and the top of the corresponding bottom plate 401 .

[0046] It should be noted that two stretching rods 402 are provided on the outside of each main pillar 1. The stretching rods 402 are inclined and form a triangle with the corresponding main pillar 1 and the base plate 401, so that the stretching rods 402 can play the role of auxiliary stretching support, thereby improving the compressive resistance and actual bearing strength of the main pillar 1.

[0047] It should also be noted that the electrical components appearing in the text are all electrically connected to the adapter power supply 301 and the monitor 304. At the same time, the adapter power supply 301 is a rechargeable power supply and is electrically connected to the main power supply of the construction site. The provision of power is common knowledge in the field. The monitor 304 is a programmable PLC controller, which can be implemented through simple programming by technicians in the field. They are all existing publicly available power connection technologies and will not be described in detail in the text.

[0048] The working principle of the above embodiment is:

[0049] When performing deformation monitoring, the laser beam emitted by the laser sensor 303 passes through each monitoring hole 312 in turn and is irradiated on the surface of the laser receiving plate 305 to be received. When the top guard plate 2 or the main pillar 1 is deformed, the laser sensor 303 or one or more monitoring plates 311 are displaced, causing the laser beam to be blocked by the monitoring plate 311, so that the laser receiving plate 305 cannot receive the laser signal. The sound and light alarm 302 can be controlled by the monitor 304 to start, which is used to warn nearby staff. After adjusting, maintaining and reinforcing the main pillar 1 or the top guard plate 2, the first locking screw 308 and the second locking screw 310 corresponding to the position offset monitoring plate 311 are loosened, and the height and angle of the monitoring plate 311 are adjusted so that the laser beam can pass through the inside of the monitoring hole 312 again. After tightening the first locking screw 308 and the second locking screw 310, it can continue to perform normal deformation monitoring work.

[0050] Compared with the prior art, the mine underground support deformation monitoring device, through the use of the monitoring mechanism 300 between the opposite sides of the two main pillars 1, can maintain, repair and reinforce the deformed support structure, and conveniently adjust the position of the test hole to facilitate continued monitoring work, thereby improving the adaptability of the overall structure, enabling it to be well adapted to the use of the underground support structure, so that related work in the mine can be carried out safely. At the same time, it also greatly improves the practicability of the underground support deformation monitoring device, and solves the problem that the existing underground support device is inconvenient to adjust the position of the offset test hole after deformation, resulting in low overall applicability.
