Description

Technical Field

[0001] The invention relates to a device for overlapping a mine pipeline and a fractured rock mass, belonging to the technical field of mine pipeline installation. Background Art

[0002] Mine pipelines are one of the more important facilities inside a mine. They are mainly used to transport media such as liquids and gases. Mine pipelines are generally installed and fixed in the mine through brackets.

[0003] For example, a Chinese patent document with publication number CN208519321U discloses a coal mine underground pipeline fixing device, which places a base at the position where the pipeline is to be laid in the coal mine, and then stably fixes the base by fixing the drill rod, and then places the pipeline between the fixed jacket and the movable jacket, and then adjusts the handwheel at the outer end of the mounting screw rod, and the handwheel drives the mounting screw rod to rotate in the screw sleeve seat, so that the mounting screw rod drives the movable plate to approach the fixed plate, so that the fixed jacket and the movable jacket are adapted, and then the connecting plates at both ends of the fixed jacket and the movable jacket are connected by bolts, so as to fix the pipeline, facilitate installation and disassembly of the pipeline, and facilitate maintenance.

[0004] However, in the actual construction process, the inner wall of the mine is usually uneven, which leads to inconsistent elevations of the pipeline fixing devices after installation, that is, the movable jackets in the pipeline fixing devices are not coaxial, and it is difficult to use them together to fix the same mine pipeline. Therefore, it is necessary to correct the installation elevation of each pipeline fixing device, which leads to extended mine pipeline installation construction time and slow installation progress. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a device for overlapping a mine pipeline and a fractured rock mass.

[0006] The present invention is achieved through the following technical solutions:

[0007] A device for splicing a mine pipeline and a fractured rock mass comprises a splicing frame, one side of the splicing frame is provided with a plurality of pipeline connectors, and a side of the splicing frame away from the pipeline connectors is provided with a plurality of tightening components.

[0008] The lap joint frame is provided with a plurality of pipe connectors, which are arc-shaped fixing plates or clamps. The lap joint frame is provided with a plurality of tightening assemblies, which include an electric cylinder and a pressing plate, and the pressing plate is arranged on the output shaft of the electric cylinder.

[0009] Two S-shaped extrusion plates are hinged on one side of the pressing plate close to the lap frame, and a torsion spring is provided between the S-shaped extrusion plate and the pressing plate. The two S-shaped extrusion plates are symmetrically arranged, and the middle parts of the two S-shaped extrusion plates are connected by elastic cloth, and the pressing plate is located between the elastic cloth and the electric cylinder.

[0010] An arc-shaped support frame is fixedly provided on one side of the S-shaped extrusion plate close to the elastic cloth, and the arc-shaped support frame is located between the elastic cloth and the pressing plate.

[0011] The middle part of the pressing plate is connected with an air supply pipe, one end of the air supply pipe passes through the pressing plate and points to the elastic cloth, and a plurality of ventilation holes are arranged on the elastic cloth.

[0012] A first elastic rope is connected to the inner side of the ventilation hole on the elastic cloth, and a streamer is connected to the middle part of the first elastic rope.

[0013] A conical guide block is connected to the middle of the streamer, and the small end of the conical guide block is close to the first elastic rope.

[0014] The device also includes a second elastic pull rope, both ends of which are connected to the arc-shaped support frames on the two S-shaped extrusion plates through a counterweight ball and a connecting rope.

[0015] A wavy rubber plate is provided on one side of the elastic cloth close to the second elastic drawstring.

[0016] The device also includes a spring sheet, which is located on a side of the S-shaped extrusion plate away from the elastic cloth, one end of the spring sheet is connected to an end of the S-shaped extrusion plate away from the pressing plate, and the other end is connected to an end of the arc-shaped support frame away from the S-shaped extrusion plate through a third elastic pull rope, and the third elastic pull rope runs through the S-shaped extrusion plate, a plurality of flexible ejector pins are provided on a side of the spring sheet close to the S-shaped extrusion plate, and a through hole is provided on the S-shaped extrusion plate at a position corresponding to the flexible ejector pin.

[0017] The beneficial effects of the present invention are:

[0018] 1. Each electric cylinder moves independently and can be extended to different lengths according to the irregular or uneven inner wall of the mine, ensuring the stability of the mine pipeline after installation in the mine; at the same time, it also reduces the construction steps such as the fixed connection between the device and the inner wall of the mine and the elevation correction of the device, shortens the installation time of the mine pipeline, and improves the installation efficiency of the mine pipeline.

[0019] 2. On the one hand, the gas ejected from the gas pipe impacts the elastic cloth and the inner wall of the mine, which helps to reduce impurities and moisture on the elastic cloth at the contact position with the pressing plate and the inner wall of the mine; on the other hand, when the counterweight ball slides on the wavy surface of the wavy rubber plate, the elastic cloth vibrates to reduce impurities remaining on the surface of the elastic cloth; both help to improve the stability of the elastic cloth when it contacts the pressing plate and the inner wall of the mine, and reduce the risk of slipping.

[0020] 3. When compressed gas passes through the vent hole, the airflow is guided by the conical guide block, so that the swing frequency of the ribbon behind it increases, which further makes the ribbon clean the inner wall of the mine more quickly, reduces the residual amount of impurities on the side wall of the mine where the ribbon contacts, and helps to improve the stability of the contact between the elastic cloth and the pressing plate and the inner wall of the mine.

[0021] 4. The pressing plate uses the roughness of the elastic cloth to increase the friction between it and the inner wall of the mine, so as to increase the stability of the pressing plate pressing on the inner wall of the mine; at the same time, when the arc-shaped support frame approaches the inner wall of the mine, one end of the arc-shaped support frame will contact the elastic cloth, and the elastic cloth can continue to contact the inner wall of the mine, thereby increasing the contact tightness between the elastic cloth and the inner wall of the mine, further improving the friction between the elastic cloth and the inner wall of the mine, and preventing the lap frame and the pressing plate from slipping on the inner wall of the mine.

[0022] 5. As the arc-shaped support frame approaches the inner wall of the mine, it will gradually fit onto the S-shaped extrusion plate. At this time, the spring sheet will be pulled onto the S-shaped extrusion plate through the third elastic pull rope. At the same time, the flexible ejector pin will pass through the through hole and press against the inner wall of the mine, thereby increasing the friction between the S-shaped extrusion plate and the mine and reducing the risk of slipping.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0031] like Figures 1 to 6 As shown, a device for overlapping a mine pipeline and a fractured rock mass described in the present invention comprises a lap frame 1, a plurality of pipe connectors are installed on one side of the lap frame 1, and a plurality of jacking assemblies are installed on the side of the lap frame 1 away from the pipe connectors. When in use, the lap frame 1 is a flat plate. When installing the mine pipeline, first connect the pipe connector to the mine pipeline, then put the mine pipeline and the device into the mine at the same time, and then make each jacking assembly to support the inner wall of the mine respectively, and at the same time, the jacking assembly reacts to the mine pipeline through the lap frame 1 and the pipe connector to install and fix the mine pipeline. Since each jacking assembly works separately and does not affect each other, when the inner wall of the mine is irregular or uneven, the device can still install and fix the mine pipeline normally, reducing the construction steps such as the fixed connection between the device and the inner wall of the mine and the elevation correction of the device, shortening the installation time of the mine pipeline, and speeding up the installation progress.

[0032] The lap joint frame 1 is provided with two pipe connectors, which are arc-shaped fixing plates 11 or clamps. The lap joint frame 1 is provided with two tightening assemblies, which include an electric cylinder 12 and a pressing plate 13 . The pressing plate 13 is provided on the output shaft of the electric cylinder 12 .

[0033] Two S-shaped extrusion plates 2 are hinged on one side of the pressing plate 13 near the bridging frame 1, and a torsion spring is installed between the S-shaped extrusion plate 2 and the pressing plate 13. The two S-shaped extrusion plates 2 are symmetrically arranged, and the middle parts of the two S-shaped extrusion plates 2 are connected by an elastic cloth 21, and the pressing plate 13 is located between the elastic cloth 21 and the electric cylinder 12. When in use, the torsion spring has a tendency to rotate the S-shaped extrusion plate 2 toward the direction close to the counterweight ball 71, and the elastic cloth 21 can also be replaced by an elastic belt. An S-shaped extrusion plate 2 is hinged on the pressing plate 13. When the electric cylinder 12 pushes the pressing plate 13 toward the inner wall of the mine, the end of the S-shaped extrusion plate 2 away from the pressing plate 13 will first contact the inner wall of the mine. When the pressing plate 13 continues to approach the inner wall of the mine, the S-shaped extrusion plate 2 will rotate in the direction away from the counterweight ball 71, and then the elastic cloth 21 will fit on the inner wall of the mine and be located between the pressing plate 13 and the inner wall of the mine. By arranging the elastic cloth 21 between the pressing plate 13 and the inner wall of the mine, the water absorption and roughness of the elastic cloth 21 can be used to increase the friction between the pressing plate 13 and the inner wall of the mine, thereby increasing the stability of the pressing plate 13 pressing on the inner wall of the mine.

[0034] The arc-shaped support frame 3 is fixedly mounted on one side of the S-shaped extrusion plate 2 close to the elastic cloth 21, and the arc-shaped support frame 3 is located between the elastic cloth 21 and the pressing plate 13. When in use, the shape of the arc-shaped support frame 3 is as follows: Figure 2 and Figure 4 As shown, the arc-shaped support frame 3 is elastic. The arc-shaped support frame 3 is installed in the middle of the S-shaped extrusion plate 2. When the S-shaped extrusion plate 2 rotates in a direction away from the counterweight ball 71, one end of the arc-shaped support frame 3 will contact the elastic cloth 21, so that during the rotation of the S-shaped extrusion plate 2, the elastic cloth 21 can continue to contact the inner wall of the mine, increase the contact tightness between the elastic cloth 21 and the inner wall of the mine, further improve the friction between the elastic cloth 21 and the inner wall of the mine, and prevent the bridging frame 1 and the pressing plate 13 from sliding on the inner wall of the mine.

[0035] The middle part of the pressing plate 13 is connected with an air pipe 4, one end of which passes through the pressing plate 13 and points to the elastic cloth 21, and a plurality of vents 41 are processed on the elastic cloth 21. After the device and the mine pipeline are placed in the mine together, the end of the air pipe 4 away from the pressing plate 13 is connected to the air outlet of the blower, or directly connected to a compressed air tank, etc. The gas ejected from the air pipe 4 will impact the elastic cloth 21, and part of the gas will pass through the vents 41 and blow onto the inner wall of the mine, which helps to reduce impurities and moisture at the contact position of the elastic cloth 21 with the pressing plate 13 and the inner wall of the mine, improve the stability of the elastic cloth 21 when it contacts the pressing plate 13 and the inner wall of the mine, and reduce the risk of slipping.

[0036] In addition, a herringbone elastic rope 95 is installed on the inner wall of one end of the gas pipe 4 near the pressing plate 13, and the top end of the herringbone elastic rope 95 extends outside the gas pipe 4 and is connected to a sealing ball 94; when airflow is ejected from the gas pipe 4, the airflow is dispersed by the sealing ball 94 to increase the blowing area and blowing effect of the airflow on the elastic cloth 21 and the inner wall of the mine. In addition, multiple nozzles or multiple gas pipes 4 can be installed on the pressing plate 13 to spray air, so as to improve the blowing effect of the airflow on the elastic cloth 21 and the inner wall of the mine.

[0037] The elastic cloth 21 is connected to a first elastic rope 5 on the inner side of the vent hole 41, and a streamer 51 is connected to the middle of the first elastic rope 5. When compressed gas passes through the vent hole 41, the streamer 51 will float on one side of the elastic cloth 21. When the elastic cloth 21 approaches the inner wall of the mine, the streamer 51 will contact the inner wall of the mine and sweep away impurities on the inner wall of the mine, which helps to improve the stability of the elastic cloth 21 when it contacts the inner wall of the mine.

[0038] The middle of the streamer 51 is connected with a conical guide block 6, and the small end of the conical guide block 6 is close to the first elastic rope 5. When compressed gas passes through the vent hole 41, the conical guide block 6 guides the airflow, so that the swing frequency of the streamer 51 behind it increases, and the streamer 51 further cleans the inner wall of the mine more quickly, reducing the residual amount of impurities on the side wall of the mine where the streamer 51 contacts, which helps to improve the stability of the contact between the elastic cloth 21 and the pressing plate 13 and the inner wall of the mine.

[0039] The device also includes a second elastic pull rope 72, both ends of which are connected to the arc-shaped support frames 3 on the two S-shaped extrusion plates 2 through the counterweight ball 71 and the connecting rope 7. When the S-shaped extrusion plate 2 rotates in a direction away from the counterweight ball 71, the second elastic pull rope 72 will be stretched, and the length of the connecting rope 7 will not change. When the elastic cloth 21 is attached to the inner wall of the mine, the counterweight ball 71 will be separated between the pressing plate 13 and the elastic cloth 21, so that the contact pressure between part of the elastic cloth 21 and the inner wall of the mine is increased, thereby improving the stability of the elastic cloth 21 and the pressing plate 13 attached to the inner wall of the mine.

[0040] A wavy rubber plate 8 is installed on one side of the elastic cloth 21 near the second elastic rope 72. That is, one side of the wavy rubber plate 8 near the weight ball 71 is wavy. The wavy rubber plate 8 is installed on the elastic cloth 21. When the second elastic rope 72 is stretched, the weight ball 71 will slide on the wavy surface of the wavy rubber plate 8, thereby causing the elastic cloth 21 to vibrate, so as to reduce impurities remaining on the surface of the elastic cloth 21, improve the stability of the elastic cloth 21 when it contacts the inner wall of the mine, and prevent the elastic cloth 21 from slipping on the inner wall of the mine.

[0041] The device also includes a spring piece 9, which is located on a side of the S-shaped extrusion plate 2 away from the elastic cloth 21, one end of the spring piece 9 is connected to an end of the S-shaped extrusion plate 2 away from the pressing plate 13, and the other end is connected to an end of the arc-shaped support frame 3 away from the S-shaped extrusion plate 2 through a third elastic pull rope 91, and the third elastic pull rope 91 passes through the S-shaped extrusion plate 2, and a plurality of flexible ejector pins 92 are installed on the side of the spring piece 9 close to the S-shaped extrusion plate 2, and a through hole 93 is processed on the S-shaped extrusion plate 2 at a position corresponding to the flexible ejector pin 92. The spring piece 9 is installed on the S-shaped extrusion plate 2, and during the process of the S-shaped extrusion plate 2 rotating in a direction away from the counterweight ball 71, the arc-shaped support frame 3 will gradually fit onto the S-shaped extrusion plate 2, and at this time, the spring piece 9 will be pulled by the third elastic pull rope 91 to fit onto the S-shaped extrusion plate 2, and at the same time, the flexible ejector pin 92 will pass through the through hole 93 and press against the inner wall of the mine, thereby increasing the friction between the S-shaped extrusion plate 2 and the mine, and reducing the risk of slipping.

[0042] The device for overlapping a mine pipeline and a fractured rock mass of the present invention has the following working principle or use process:

[0043] Install at least two sets of Figure 1 In the device shown, the arc-shaped fixing plate 11 in the device is connected to the mine pipe, and the mine pipe and the device are placed in the mine at the same time, and then each electric cylinder 12 is controlled to extend, and the electric cylinder 12 presses the pressing plate 13 and the elastic cloth 21 against the inner wall of the mine, and at the same time, the pressing plate 13 reacts to the mine pipe through the electric cylinder 12 and the arc-shaped fixing plate 11, so that the mine pipe is installed and fixed. Each electric cylinder 12 acts independently and can be extended to different lengths for irregular or uneven inner walls of the mine, ensuring that the mine pipe is stable after installation in the mine. At the same time, compared with the prior art, it also reduces the construction steps such as the fixed connection between the pipeline fixing device and the inner wall of the mine and the elevation correction of the pipeline fixing device, shortens the mine pipe installation time, and improves the mine pipe installation efficiency.
