Description

Technical Field

[0001] The present invention relates to the technical field of coal mine safety detection, and in particular to a high-precision multi-point roof separation instrument and an installation method thereof. Background Art

[0002] The roof separation meter is a special monitoring instrument for monitoring the movement of roof rock layers. Through comprehensive roof separation observations of various anchor network tunnels, it is generally recognized that roof separation observations play a certain guiding and warning role in the support and reform of anchor network tunnels. According to the data analysis observed by the roof separation meter, different geological conditions, rock property changes, etc. are obtained, and the separation amount within the anchor network range of the anchor network tunnel is summarized, and effective support measures are taken in time to prevent the occurrence of roof collapse accidents and ensure safe production. At the same time, it provides technical means to study the distribution and transfer law of support pressure in the mining area, the deformation law of tunnel surrounding rock, identify tunnel stability, study and determine the critical value of roof instability and separation, study the movement status of tunnel surrounding rock, and analyze the stability of surrounding rock.

[0003] The roof separation meter currently used on the market mainly works by extending anchor claws connected to steel wire ropes into drill holes in the roof, anchoring them in rock layers at different depths, and predicting roof separation accidents by monitoring the displacement between different rock layers. Generally speaking, the more anchor claws anchored in the borehole, the more anchor points, and the more rock layers monitored, the more accurate the prediction of roof separation accidents, and the higher the accuracy of the roof separation meter. However, the current roof separation meter has more anchor claws, and the steel wire ropes connected to the anchor claws will interfere with each other. Therefore, basically only two anchor claws are set at the shallow base point and the deep base point. There is still a big problem in the prediction accuracy. At the same time, the anchor head of the roof separation meter in the existing technology generally adopts a barb-like structure, which can only be pushed into the borehole and cannot be moved outside the borehole. The roof separation meter cannot be reused after one installation, which makes the coal mine safety detection cost high. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a high-precision multi-point roof separation meter and an installation method thereof. The high-precision multi-point roof separation meter and the corresponding installation method realize the recyclable and stable installation of the high-precision multi-point roof separation meter through an air-controlled anchoring assembly and an air-controlled installation assembly, and during use, the steel wire ropes at each point will not be interfered with.

[0005] The technical solutions of the present invention are as follows:

[0006] A high-precision multi-point roof separation instrument includes a detection part, a mounting part and an anchoring part. The mounting part is fixedly connected to the detection part, and the anchoring part is connected to the detection part by a steel wire rope passing through the mounting part. The anchoring part is composed of a circular ring part and a flat plate part. At least two air-controlled anchoring components are evenly arranged on the circular ring part. A piston hole II is provided on the circular ring part. The air-controlled anchoring component includes a piston rod II. The piston rod II is airtightly slidably installed in the piston hole II. A spring II is provided between the piston portion of rod II and the bottom of piston hole II. A cover plate II is airtightly mounted at the opening of piston hole II. The insertion portion of piston rod II airtightly passes through cover plate II, and the end of the insertion portion of piston rod II is pointed. An air path II is provided on the anchoring portion, and the air path II connects the air inlet and outlet II provided at the bottom of the flat plate portion with the air cavity between piston rod II and cover plate II. A plurality of rope holes I are provided on the flat plate portion, and one end of a steel wire rope is fixedly connected to rope hole I.

[0007] When compressed air is passed through air circuit II, the compressed air causes the piston rod II to slide toward the bottom of the piston hole II, and the rod portion of the piston rod II does not exceed the circular ring portion. When the compressed air in air circuit II is exhausted, the spring II causes the piston rod II to slide toward the outside of the piston hole II, and the rod portion of the piston rod II extends out of the circular ring portion.

[0008] Furthermore, the extending direction of the piston rod II is obliquely downward.

[0009] Furthermore, the mounting portion is composed of several sections of mounting tubes, transverse partitions and longitudinal partitions fixedly connected, the transverse partition is arranged between two mounting tubes, the longitudinal partition is arranged in the mounting tube to divide the interior of the mounting tube into several rope cavities, and the transverse partition is provided with a rope cavity corresponding to the mounting tube;

[0010] The lower end of the mounting portion is inserted into the detection box of the detection portion;

[0011] At least two air-controlled mounting assemblies are evenly distributed on the transverse diaphragm. A piston hole I is provided on the transverse diaphragm. The air-controlled mounting assembly includes a piston rod I, which is airtightly and slidably mounted in the piston hole I. A spring I is provided between the piston portion of the piston rod I and the bottom of the piston hole I. A cover plate I is airtightly mounted at the opening of the piston hole I. The rod portion of the piston rod I airtightly passes through the cover plate I, and the rod portion of the piston rod I is pointed. An air circuit I is provided on the mounting portion, which connects the air inlet and outlet I provided on the longitudinal diaphragm at the bottom end of the mounting portion with the air cavity between the piston rod I and the cover plate I.

[0012] When compressed air is passed through air circuit I, the compressed air causes the piston rod I to slide toward the bottom of the piston hole I, and the rod portion of the piston rod I does not extend beyond the mounting tube body. When the compressed air in air circuit I is exhausted, the spring I causes the piston rod I to slide out of the piston hole I, and the rod portion of the piston rod I extends out of the mounting tube body.

[0013] Furthermore, a plug is installed at the upper end of the installation portion, and rope holes II matching the number of rope cavities are provided on the plug.

[0014] A method for installing a high-precision multi-point roof separation instrument comprises the following steps:

[0015] S1: Fix one end of the wire rope to the anchoring part;

[0016] S2: Installing several anchoring parts in the anchoring holes in sequence;

[0017] S3: Install the mounting part into the mounting hole.

[0018] Furthermore, a special installation tool is required in steps S2 and S3. The installation tool includes a portable air compressor and a mounting rod. The mounting rod is connected to the compressed air outlet of the portable air compressor.

[0019] Furthermore, in step S2, the portable air compressor is started, one end of the mounting rod is connected to the compressed air outlet of the portable air compressor, and the other end is connected to the air inlet and outlet II of the anchoring part. The compressed air causes the piston rod II to slide toward the bottom of the piston hole II, and the rod portion of the piston rod II does not exceed the annular portion. The mounting rod pushes the anchoring part into the anchoring hole, and the portable air compressor is stopped. The spring II causes the piston rod II to slide out of the piston hole II, and the rod portion of the piston rod II extends out of the annular portion and is inserted into the wall of the anchoring hole, thereby realizing the anchoring of the anchoring part and the anchoring hole, and the mounting rod is removed from the anchoring part.

[0020] Furthermore, in step S3, the portable air compressor is started, and the compressed air outlet of the portable air compressor is connected to the air inlet and outlet Ⅰ at the bottom end of the mounting part through a hose. The compressed air causes the piston rod Ⅰ to slide toward the bottom of the piston hole Ⅰ, and the rod portion of the piston rod Ⅰ does not exceed the mounting tube body. The mounting part is inserted into the mounting hole, and the portable air compressor is stopped. The spring Ⅰ causes the piston rod Ⅰ to slide out of the piston hole Ⅰ, and the rod portion of the piston rod Ⅰ extends out of the mounting tube body and is inserted into the wall of the mounting hole, thereby fixing the mounting part and the mounting hole.

[0021] Further, the steps of disassembling the high-precision multi-point roof separation instrument include:

[0022] C1: Remove the mounting part from the mounting hole;

[0023] C2: Remove several anchoring parts from the anchoring holes one by one.

[0024] Furthermore, in step C1, the portable air compressor is started, and the compressed air outlet of the portable air compressor is connected to the air inlet and outlet I at the bottom end of the mounting portion through a hose. The compressed air causes the piston rod I to slide toward the bottom of the piston hole I, and the insertion portion of the piston rod I does not extend beyond the mounting tube body. The mounting portion is pulled out of the mounting hole, the portable air compressor is stopped, and the compressed air outlet is disconnected from the air inlet and outlet I at the bottom end of the mounting portion.

[0025] In step C2, one end of the mounting rod is connected to the compressed air outlet of the portable air compressor, and the other end is connected to the air inlet and outlet II of the anchoring part. The portable air compressor is started, and the compressed air causes the piston rod II to slide toward the bottom of the piston hole II. The rod portion of the piston rod II is retracted and does not exceed the annular portion. The mounting rod removes the anchoring part from the anchoring hole. The portable air compressor is stopped, and the mounting rod is removed from the anchoring part.

[0040] like Figure 1 As shown, the high-precision multi-point roof separation instrument includes a detection part 1, a mounting part 2 and an anchoring part 3. The mounting part 2 is fixedly connected to the detection part 1, and the anchoring part 3 is connected to the detection part 1 through a wire rope 4 passing through the mounting part 2. The present technical solution does not limit the specific detection method of the detection part 1. It mainly improves the mounting part 2 and the anchoring part 3. The different specific structures of the detection part 1 will not have a substantial impact on this patent application. Specifically, in the Chinese invention patent application with application number 202111309010.X, the sensor body in the patent is equivalent to the detection part 1 in this solution. For example, in the Chinese utility model patent with application number 202121989008.7, the detection part in the patent is equivalent to the detection part 1 in this solution.

[0041] like Figure 6 and Figure 7As shown, the anchoring portion 3 is composed of a circular ring portion 3a and a flat plate portion 3b, and four air-controlled anchoring components are evenly arranged on the circular ring portion 3a. Preferably, in other embodiments, at least two air-controlled anchoring components are evenly arranged to enable the anchoring portion 3 to be stably anchored in the anchoring hole. A piston hole II3a1 is provided on the circular ring portion 3a, and the air-controlled anchoring component includes a piston rod II3d, and the piston rod II3d is airtightly slidably installed in the piston hole II3a1. A spring II3f is provided between the piston portion of the piston rod II3d and the bottom of the piston hole II3a1. The cover plate II3e is airtightly installed at the orifice of the piston hole II3a1, and the rod portion of the piston rod II3d passes through the cover plate II3e airtightly. The piston rod The end of the insertion rod portion of Ⅱ3d is a pointed tip; an air circuit Ⅱ3c is provided on the anchoring portion 3, and the air circuit Ⅱ3c connects the air inlet and outlet Ⅱ3c1 provided at the bottom of the flat portion 3b and the air cavity between the piston insertion rod Ⅱ3d and the cover plate Ⅱ3e; a plurality of rope holes Ⅰ3b1 are provided on the flat portion 3b, and one end of the wire rope 4 is fixedly connected to the rope hole Ⅰ3b1. The number of rope holes Ⅰ3b1 is consistent with the number of points of the high-precision multi-point delamination instrument. In this embodiment, it is an 8-point delamination instrument, so there are 8 rope holes Ⅰ3b1 evenly distributed; ordinary technicians in this field should pay attention to a design common sense when doing construction design, that is, the air circuit Ⅱ3c cannot interfere with the rope hole Ⅰ3b1, and the position of the rope hole Ⅰ3b1 should be bypassed when arranging the air circuit Ⅱ3c.

[0042] When compressed air flows through air path II3c, the compressed air causes the piston rod II3d to slide toward the bottom of the piston hole II3a1, and the rod portion of the piston rod II3d does not extend beyond the annular portion 3a. When the compressed air in air path II3c is exhausted, the spring II3f causes the piston rod II3d to slide out of the piston hole II3a1, and the rod portion of the piston rod II3d extends out of the annular portion 3a.

[0043] Preferably, the piston rod II 3d extends in an obliquely downward direction. The oblique setting has two advantages. First, the downward direction can make the piston rod II 3d more firmly inserted into the wall of the anchor hole. Second, the piston rod II 3d can be set longer in a limited space.

[0044] like Figure 2 、 Figure 3 and Figure 4 As shown, the mounting portion 2 is composed of several sections of mounting tubes 2a, transverse partitions 2b and longitudinal partitions 2c fixedly connected. The transverse partition 2b is arranged between two mounting tubes 2a, and the longitudinal partition 2c is arranged inside the mounting tube 2a to divide the interior of the mounting tube 2a into several rope cavities. Specifically, in this embodiment, there are 8 rope cavities. The transverse partitions 2b are provided with rope cavities corresponding to the mounting tubes 2a.

[0045] The lower end of the mounting portion 2 is inserted into the detection box 1a of the detection portion 1;

[0046] At least two air-controlled mounting assemblies are evenly distributed on the diaphragm 2b. Specifically, in this embodiment, four air-controlled mounting assemblies are provided. A piston hole Ⅰ2b1 is provided on the diaphragm 2b. The air-controlled mounting assembly includes a piston rod Ⅰ2e. The piston rod Ⅰ2e is airtightly slidably installed in the piston hole Ⅰ2b1. A spring Ⅰ2g is provided between the piston portion of the piston rod Ⅰ2e and the bottom of the piston hole Ⅰ2b1. The cover plate Ⅰ2f is airtightly installed at the opening of the piston hole Ⅰ2b1. The rod portion of the piston rod Ⅰ2e airtightly passes through the cover plate Ⅰ2f. The rod portion of the piston rod Ⅰ2e is pointed. An air path Ⅰ2d is provided on the mounting portion 2. The air path Ⅰ2d connects the air inlet and outlet Ⅰ2d1 provided on the longitudinal diaphragm 2c at the bottom end of the mounting portion 2 and the air cavity between the piston rod Ⅰ2e and the cover plate Ⅰ2f.

[0047] When compressed air flows through the air circuit Ⅰ2d, the compressed air causes the piston rod Ⅰ2e to slide toward the bottom of the piston hole Ⅰ2b1, and the rod portion of the piston rod Ⅰ2e does not extend beyond the mounting tube body 2a. When the compressed air in the air circuit Ⅰ2d is exhausted, the spring Ⅰ2g causes the piston rod Ⅰ2e to slide out of the piston hole Ⅰ2b1, and the rod portion of the piston rod Ⅰ2e extends out of the mounting tube body 2a.

[0048] like Figure 2 and Figure 5 As shown, a plug 5 is installed at the upper end of the installation portion 2. The plug 5 is preferably made of rubber material, and 8 rope holes II 5a are evenly distributed on the plug 5 to match the number of rope cavities.

[0049] The installation method of the high-precision multi-point roof separation instrument includes the following steps:

[0050] S1: Fix one end of the wire rope 4 to the anchoring portion 3;

[0051] S2: Install several anchoring parts 3 in the anchoring holes in sequence;

[0052] S3: Install the mounting portion 2 in the mounting hole.

[0053] Furthermore, in steps S2 and S3, a special installation tool is required, which includes a portable air compressor and a mounting rod. The mounting rod is hollow and ventilated, and the mounting rod is connected to the compressed air outlet of the portable air compressor.

[0054] The eight anchoring parts 3 are installed sequentially. In step S1, the rope hole Ⅰ3b1 of the bottom anchoring part 3 is passed through the seven steel ropes 4 extending from the detection part 1. Another steel rope 4 is fixed to the rope hole Ⅰ3b1. Then, it passes through 6, 5, 4, 3, 2, 1, and 0 in sequence. At the same time, another steel rope 4 is fixed to the rope hole Ⅰ3b1 different from the rope hole Ⅰ3b1 of the anchoring part 3 below.

[0055] In step S2, the portable air compressor is started, one end of the mounting rod is connected to the compressed air outlet of the portable air compressor, and the other end is connected to the air inlet and outlet Ⅱ3c1 of the anchoring part 3. Specifically, the air inlet and outlet Ⅱ3c1 is provided with a sealing pipe thread, and one end of the mounting rod is provided with a sealing pipe thread that matches the air inlet and outlet Ⅱ3c1. The mounting rod is detachably connected to the air inlet and outlet Ⅱ3c1 through the pipe thread, and the compressed air causes the piston rod Ⅱ3d to slide to the bottom of the piston hole Ⅱ3a1, and the rod portion of the piston rod Ⅱ3d does not exceed the annular portion 3a. The mounting rod pushes the anchoring part 3 into the anchoring hole, and the portable air compressor is stopped. The spring Ⅱ3f causes the piston rod Ⅱ3d to slide outside the piston hole Ⅱ3a1, and the rod portion of the piston rod Ⅱ3d extends out of the annular portion 3a and is inserted into the wall of the anchoring hole, thereby realizing the anchoring of the anchoring part 3 and the anchoring hole, and the mounting rod is removed from the anchoring part 3.

[0056] In step S3, start the portable air compressor, connect the compressed air outlet of the portable air compressor to the air inlet and outlet Ⅰ2d1 at the bottom end of the mounting part 2 through a hose, and the compressed air causes the piston rod Ⅰ2e to slide to the bottom of the piston hole Ⅰ2b1, and the rod portion of the piston rod Ⅰ2e does not exceed the mounting tube body 2a. Insert the mounting part 2 into the mounting hole, stop the portable air compressor, and the spring Ⅰ2g causes the piston rod Ⅰ2e to slide out of the piston hole Ⅰ2b1. The rod portion of the piston rod Ⅰ2e extends out of the mounting tube body 2a and is inserted into the wall of the mounting hole, thereby fixing the mounting part 2 to the mounting hole.

[0057] The steps to disassemble the high-precision multi-point roof separation instrument include:

[0058] C1: Remove the mounting portion 2 from the mounting hole;

[0059] C2: Remove several anchoring parts 3 from the anchoring holes one by one.

[0060] In step C1, the portable air compressor is started, and the compressed air outlet of the portable air compressor is connected to the air inlet and outlet port I2d1 at the bottom end of the mounting portion 2 via a hose. The compressed air causes the piston rod I2e to slide toward the bottom of the piston hole I2b1, and the insertion portion of the piston rod I2e does not extend beyond the mounting tube body 2a. The mounting portion 2 is then removed from the mounting hole, the portable air compressor is stopped, and the compressed air outlet is disconnected from the air inlet and outlet port I2d1 at the bottom end of the mounting portion 2.

[0061] In step C2, one end of the mounting rod is connected to the compressed air outlet of the portable air compressor, and the other end is connected to the air inlet and outlet Ⅱ3c1 of the anchoring part 3. The portable air compressor is started, and the compressed air causes the piston rod Ⅱ3d to slide toward the bottom of the piston hole Ⅱ3a1. The insertion rod portion of the piston rod Ⅱ3d is retracted and does not exceed the annular portion 3a. The mounting rod removes the anchoring part 3 from the anchoring hole, stops the portable air compressor, and removes the mounting rod from the anchoring part 3.

[0062] The high-precision multi-point roof separation instrument and the supporting installation method realize the recyclable and stable installation of the high-precision multi-point roof separation instrument through the air-controlled anchoring component and the air-controlled installation component, and during use, the steel wire ropes at each point will not be interfered with.
