Description

Technical Field

[0001] The present invention relates to the technical field of mining equipment, and more specifically, to an anchor cable installation device with uniform grouting for coal mine roadways. Background Art

[0002] Through-anchor cable reinforcement is a type of anchor cable reinforcement, which is very different from ordinary anchor cable reinforcement. Ordinary anchor cable reinforcement fixes one end of the anchor cable in the rock formation and fixes the other end of the anchor cable outside the rock formation through nuts, anchor cable plates, etc. to achieve the reinforcement of the rock mass. Through-anchor cable reinforcement is aimed at the reinforcement of the rock mass between adjacent roadways. It is necessary to drill a through-hole in the rock formation between the two roadways, pass the anchor cable through the through-hole, fix both ends, and grout the through-hole to fix it to achieve the reinforcement of the rock mass. During the construction of through-anchor cable reinforcement, it is necessary to manually push the anchor cable into the penetrated anchor cable hole. The length of the penetrated anchor cable hole is about 35 meters. It is necessary to pass one end of the anchor cable through the anchor cable hole and fix it. After applying prestress to the anchor cable, grout is injected into the anchor cable hole. When using the existing anchor cable installation equipment to install the anchor cable, if the anchor cable is blocked by the protrusion of the anchor cable hole, the end of the anchor cable cannot continue to move along the anchor cable hole. If the anchor cable installation equipment is not stopped in time, resulting in the continuous delivery of the rear anchor cable into the anchor cable hole, it will cause the local bending of the anchor cable in the anchor cable hole, making the anchor cable unable to penetrate the entire anchor cable hole. Summary of the Invention

[0003] In order to overcome the above technical problems, the present invention provides an anchor cable installation device with uniform grouting for coal mine roadways with a stable anchoring layer.

[0004] The technical solution adopted by the present invention is as follows:

[0009] Preferably, the grouting mechanism includes a first sliding plate which is slidably connected to the upper side of the support plate. The first sliding plate is fixedly connected with a sealing column. A circular through-hole is arranged in the middle of the sealing column. The axis line of the sealing column coincides with the axis line of the rotating ring. The support plate is fixedly connected with a second push rod electrically connected to the control panel. The telescopic end of the second push rod is fixedly connected with the first sliding plate. The sealing column is axially and equidistantly and penetratingly fixedly connected with grouting pipes. The adjacent grouting pipes are communicated with an annular connecting pipe at one end close to the rotating ring. The annular connecting pipe is communicated with the liquid outlet of the grouting equipment through a conduit.

[0010] Preferably, a soft rubber for increasing the sealing property is arranged on the outer side surface of the sealing column, and the right middle part on the outer side of the sealing column gradually increases from the right side straight down.

[0011] Preferably, an annular groove is arranged on the inner ring surface of the sealing column. The sealing and clamping assembly includes a sealing film which is fixedly connected to the annular groove of the sealing column. The sealing film and the sealing column cooperate to form a cavity which is filled with hydraulic oil. The sealing film is made of an elastic and wear-resistant material. The sealing column is penetratingly fixedly connected with a liquid inlet pipe. One end of the liquid inlet pipe is communicated with the cavity, and the other end of the cavity is connected with a hydraulic pump electrically connected to the control panel.

[0012] Preferably, a cable rotating mechanism is further included.

[0013] Preferably, the guiding pipe is arranged in an arc shape to change the moving direction of the cable, and the inner wall of the guiding pipe is arranged as a smooth surface to reduce the friction force received by the cable in the guiding pipe.

The telescopic end of the reciprocating telescopic device is fixedly connected with the second sliding plate.

[0015] The beneficial technical effects of the present invention are:

[0016] 1. This cable anchor installation device drives the cable anchor to move leftward along the guide rod through the clamping jaws of the moving frame and inserts it into the cable anchor, improving the manual pushing of the cable anchor into the cable anchor hole and reducing the labor intensity of the staff; the rotating ring drives the cable anchor to twist reciprocally through the clamping jaws, avoiding the obstruction of the cable anchor end during the movement due to the unevenness of the cable anchor hole, resulting in the cable anchor bending in the cable anchor hole and shortening the distance between the two ends of the cable anchor, causing the cable anchor end to not pass through the cable anchor hole.

[0017] 2. The soft rubber on the outer side of the sealing column is extruded and deformed, improving the sealing performance between the sealing column and the cable anchor hole. At the same time, the conical surface on the right part of the sealing column increases the extrusion force between the sealing column and the cable anchor hole, preventing the grouting material from overflowing between the sealing column and the cable anchor hole during the grouting process.

[0018] 3. The sealing film is wrapped around the outside of the cable anchor, and at the same time, pressure is provided by the hydraulic pump to tightly clamp and seal the cable anchor with the sealing film. Using the sealing film to tightly clamp and seal the cable anchor can prevent the cable anchor from rubbing against the moving frame during the reset process of the moving frame, resulting in the cable anchor moving to the right after being subjected to the frictional force generated by the moving frame, causing the cable anchor end to fall out of the cable anchor hole and affecting the normal operation of this cable anchor installation device; at the same time, it can prevent the grouting material from overflowing from the circular through-hole of the sealing column during the grouting process.

[0019] 4. Four grouting pipes are used to simultaneously pour the grouting material into the cable anchor hole, enabling the grouting material to be evenly distributed up and down and poured into the cable anchor hole, preventing air bubbles from being generated in the cable anchor hole and causing voids in the solidified mud layer.

[0020] 5. The guide pipe drives the cable anchor to swing up and down, overcoming the torsion generated during the rotation of the cable anchor itself and preventing the cable anchor from slipping due to excessive self-torsion with the clamping jaws.

[0021] 6. The second sliding plate quickly impacts on the cable anchor, causing the cable anchor to vibrate. During the process of grouting into the cable anchor hole, the vibration of the cable anchor is used to increase the moving speed of the grouting material in the cable anchor hole. At the same time, the vibration generated by the cable anchor can also make the grouting material evenly distributed in the cable anchor hole and flow uniformly to the left along the cable anchor hole, preventing the grouting material from being unevenly distributed in the cable anchor hole and causing voids, resulting in a reduction in the reinforcement effect of the cable anchor on the rock mass.

[0036] Example 1

[0037] In an embodiment of the present invention, a cable anchor installation device with uniform grouting for coal mine tunnels is provided, such as Figures 1 - 7 As shown, it includes a driving vehicle 101, the driving vehicle 101 is bolted with an electric lifting frame 102, the driving vehicle 101 is bolted with a control panel 103, the upper part of the electric lifting frame 102 is bolted with a support plate 104, the rear side of the support plate 104 is welded with a guide rod 105 through a mounting plate, the front side of the support plate 104 is rotatably connected with a threaded rod 106 through a mounting plate, the right side of the support plate 104 is bolted with a first driving motor 107 through a mounting seat, the output shaft of the first driving motor 107 is welded with the threaded rod 106, a moving frame 108 is arranged between the guide rod 105 and the threaded rod 106, the guide rod 105 is slidably connected to the moving frame 108, the threaded rod 106 is threadedly connected to the moving frame 108, the threaded rod 106 drives the moving frame 108 to move back and forth through the thread, so that the anchor cable is intermittently inserted into the anchor cable hole, and the moving frame 108 is rotatably connected with a rotating ring 1 09. The inner ring surface of the rotating ring 109 is welded with fixed seats 110 at equal intervals in the circumferential direction. The fixed seats 110 are rotatably connected with a rotating shaft 111. The rotating shaft 111 is fixedly connected with a connecting rod 112. A torsion spring 113 is fixedly connected between the connecting rod 112 and the adjacent fixed seat 110. A claw 114 for clamping the anchor cable is hinged on the left end of the connecting rod 112. A rotating assembly is arranged on the right side of the movable frame 108. The rotating assembly is coordinated with the rotating ring 109 to make the anchor cable reciprocate in the circumferential direction of the anchor cable hole. The rotating assembly is used to drive the anchor cable to reciprocate. A clamping assembly is arranged on the right side of the movable frame 108. The clamping assembly is used to drive the adjacent claws 114 to clamp the anchor cable. A grouting mechanism is arranged on the left side of the support plate 104. The grouting mechanism is used to evenly grout the anchor cable hole in the tunnel. The electric lifting frame 102, the first driving motor 107, the rotating assembly and the clamping assembly are all electrically connected to the control panel 103.

[0038] like Figure 2As shown in the figure, the rotating assembly includes a second driving motor 115. The second driving motor 115 is bolted to the right side of the moving frame 108 through a mounting seat. The second driving motor 115 is electrically connected to the control panel 103. A first gear 116 is key-connected to the output shaft of the second driving motor 115. The first gear 116 is in transmission with the rotating ring 109. The rotating ring 109 drives the anchor cable to twist reciprocally through the claw 114. The connecting rod 112 rotates along the outer side surface of the extrusion shell 203 through a ball, avoiding the blockage during the movement of the end of the anchor cable due to the unevenness in the anchor cable hole, resulting in the bending of the anchor cable in the anchor cable hole and the shortening of the distance between the two ends of the anchor cable, so that the end of the anchor cable cannot pass through the anchor cable hole. A circle of teeth is provided on the outer ring surface of the rotating ring 109, and the first gear 116 meshes with the rotating ring 109.

[0039] As Figure 5 As shown in the figure, the clamping assembly includes symmetrically distributed first fixing plates 201. The symmetrically distributed first fixing plates 201 are both bolted to the right side of the moving frame 108. A chute is provided in the middle of the first fixing plate 201. A sliding rod 202 is slidably connected in the chute of the first fixing plate 201. An extrusion shell 203 is welded between adjacent sliding rods 202. The left side of the extrusion shell 203 is tapered. The connecting rod 112 is in extrusion fit with the outer side surface of the extrusion shell 203. A ball is rotatably connected to the end of the connecting rod 112 away from the claw 114. The outer side surface of the extrusion shell 203 is a smooth surface, reducing the wear between the extrusion shell 203 and the connecting rod 112 and improving the service life of the anchor cable installation device. The first fixing plate 201 is bolted with a first push rod 204 electrically connected to the control panel 103 through a mounting seat. The telescopic end of the first push rod 204 is welded to the adjacent sliding rod 202. The extrusion shell 203 moves to the left, making the claw 114 connected to the left end of the connecting rod 112 approach the anchor cable, so that the claw 114 fixes the anchor cable.

[0040] As Figures 6 - 7As shown in the figure, the grouting mechanism includes a first sliding plate 301. The first sliding plate 301 is slidably connected to the upper side of the support plate 104. The first sliding plate 301 is bolted with a sealing column 302. The outer side of the sealing column 302 is provided with soft rubber for enhancing the sealing performance. And the outer side of the sealing column 302 gradually increases from the middle to the right side in a straight-down manner. The soft rubber on the outer side of the sealing column 302 is extruded and deformed, increasing the contact area between the sealing column 302 and the anchor cable hole, improving the sealing performance between the sealing column 302 and the anchor cable hole, and preventing the grouting material from overflowing between the sealing column 302 and the anchor cable hole during the grouting process. A circular through-hole is provided in the middle of the sealing column 302. The axis of the sealing column 302 coincides with the axis of the rotating ring 109. The support plate 104 is bolted with a second push rod 303 electrically connected to the control panel 103 through a mounting plate. The telescopic end of the second push rod 303 is welded to the first sliding plate 301. The grouting pipes 304 are axially and equidistantly welded through the sealing column 302. One end of the adjacent grouting pipes 304 close to the rotating ring 109 is communicated with an annular connecting pipe 305. The annular connecting pipe 305 is communicated with the liquid outlet of the grouting equipment through a conduit.

[0041] As Figure 7 shown in the figure, an annular groove is provided on the inner ring surface of the sealing column 302. The sealing and clamping assembly includes a sealing film 306. The sealing film 306 is fixedly connected to the annular groove of the sealing column 302. The sealing film 306 and the sealing column 302 cooperate to form a cavity 307. The cavity 307 is filled with hydraulic oil. The sealing film 306 is made of an elastic and wear-resistant material, increasing the contact area between the sealing film 306 and the anchor cable, improving the sealing effect between the sealing film 306 and the anchor cable. The sealing column 302 is fixedly connected with a liquid inlet pipe 308 in a through manner. One end of the liquid inlet pipe 308 is communicated with the cavity 307. The other end of the cavity 307 is connected with a hydraulic pump electrically connected to the control panel 103. The hydraulic pump injects hydraulic oil into the cavity 307 along the liquid inlet pipe 308. The volume of the hydraulic oil in the cavity 307 continuously increases. The hydraulic oil extrudes the sealing film 306 to make it deformed. The sealing film 306 wraps around the outer side of the anchor cable. At the same time, the hydraulic pump provides pressure to seal and clamp the anchor cable with the sealing film 306.

[0042] When using this anchor cable installation device, the staff first pass one end of the anchor cable through the extrusion shell 203 and the rotating ring 109. Subsequently, the staff input the height position of the anchor cable hole into the control panel 103. The control panel 103 then activates two first push rods 204. The telescopic ends of the two first push rods 204 drive the adjacent sliding rods 202 to move leftward along the sliding grooves of the first fixing plate 201. The two sliding rods 202 drive the extrusion shell 203 to move leftward. The balls of the connecting rod 112 roll along the inclined surface of the extrusion shell 203, causing the right end of the connecting rod 112 to move away from the anchor cable, and at the same time, the left end of the connecting rod 112 to move closer to the anchor cable. As the extrusion shell 203 moves leftward, the torsion spring 113 is tightened, and at the same time, the adjacent claw 114 is pressed against the outside of the anchor cable to fix the anchor cable. The control panel 103 then closes the first push rod 204. The control panel 103 activates the electric lifting frame 102 according to the position of the anchor cable hole. The electric lifting frame 102 drives the support plate 104 and other components thereon to move upward. When the axis line of the sealing column 302 coincides with the axis line of the anchor cable hole, the control panel 103 closes the electric lifting frame 102. The control panel 103 then activates the second push rod 303. The telescopic end of the second push rod 303 drives the first sliding plate 301 to move leftward. The first sliding plate 301 drives the sealing column 302 to insert into the anchor cable hole. As the sealing column 302 moves leftward, the soft rubber on the outer surface of the sealing column 302 is squeezed and deformed, increasing the contact area between the sealing column 302 and the anchor cable hole, improving the sealing performance between the sealing column 302 and the anchor cable hole, and preventing the grouting material from overflowing between the sealing column 302 and the anchor cable hole during the grouting process.

[0043] The control panel 103 then starts the first drive motor 107. The output shaft of the first drive motor 107 drives the threaded rod 106 to rotate clockwise. The threaded rod 106 drives the moving frame 108 and its components to move leftward along the guide rod 105 through the thread. The claw 114 drives the anchor cable to move leftward. The left end of the anchor cable is inserted into the circular through-hole of the sealing column 302. Then the control panel starts the hydraulic pump. The hydraulic pump injects hydraulic oil into the cavity 307 along the liquid inlet pipe 308. The volume of the hydraulic oil in the cavity 307 continuously increases. The hydraulic oil squeezes the sealing film 306 to make it deform. The sealing film 306 wraps around the outside of the anchor cable. At the same time, the pressure provided by the hydraulic pump makes the sealing film 306 seal and clamp the anchor cable, preventing the anchor cable from moving rightward due to the frictional force generated by the moving frame 108 on it during the reset process of the moving frame 108, which may cause the end of the anchor cable to fall out of the anchor cable hole and affect the normal operation of this anchor cable installation device. The control panel 103 starts the first push rod 204 again. The first push rod 204 drives the extrusion shell 203 to move to the right through the sliding rod 202. The extrusion shell 203 releases the extrusion on the connecting rod 112. Under the torsion of the torsion spring 113, the claw 114 moves away from the anchor cable. The control panel 103 then controls the output shaft of the second drive motor 115 to rotate counterclockwise. The threaded rod 106 rotates counterclockwise and drives the moving frame 108 and its components to reset through the thread. When the moving frame 108 is reset, the hydraulic pump discharges the hydraulic oil in the cavity 307. The sealing film 306 resets and loses contact with the anchor cable. Repeat the above steps to insert the anchor cable into the anchor cable hole. During the process of inserting the anchor cable into the anchor cable hole, the control panel 103 starts the second drive motor 115. The output shaft of the second drive motor 115 drives the first gear 116 to rotate reciprocally. The first gear 116 drives the rotating ring 109 and its other components to rotate reciprocally along the moving frame 108. The rotating ring 109 drives the anchor cable to twist reciprocally through the claw 114. The connecting rod 112 rotates along the outer side surface of the extrusion shell 203 through the ball, so that the end of the anchor cable rotates reciprocally in the anchor cable hole, avoiding the convex parts of the anchor cable hole. This prevents the unevenness in the anchor cable hole from blocking the movement of the end of the anchor cable during the movement of the anchor cable along the anchor cable hole, causing the anchor cable to bend and resulting in a shorter distance between the two ends of the anchor cable, so that the end of the anchor cable cannot pass through the anchor cable hole. If the end of the anchor cable is inserted into the gap of the anchor cable hole, the control panel 103 will control the first drive motor 107 to move reciprocally along the guide rod 105 to prevent the end of the anchor cable from being inserted into the gap of the anchor cable hole, which may cause obstruction when the anchor cable moves along the anchor cable hole. When the end of the anchor cable passes through the other side of the anchor cable hole, stop the above steps and turn off the first drive motor 107.

[0044] The staff fixes the left end of the anchor cable. Subsequently, the control panel 103 starts the first driving motor 107, so that the moving frame 108 drives the anchor cable to pull to the right through the claw 114, applying prestress to the anchor cable. Then the staff starts the grouting equipment, and the grouting equipment injects the grouting material into the annular connecting pipe 305. The grouting material is poured into the anchor cable hole along the four grouting pipes 304. By using the four grouting pipes 304 to pour the grouting material into the anchor cable hole simultaneously, the grouting material is evenly distributed up and down into the anchor cable hole, avoiding the generation of air bubbles in the anchor cable hole and causing voids in the solidified mud layer. As the grouting material is continuously poured into the anchor cable hole, the grouting material flows to the left along the anchor cable hole. The sealing film 306 is wrapped around the outside of the anchor cable to increase the contact area between the sealing film 306 and improve the sealing between the sealing film 306 and the anchor cable, preventing the grouting material from overflowing from the circular through-hole of the sealing column 302. When the anchor cable hole is filled with the grouting material, the staff then turns off the grouting equipment. Subsequently, the control panel 103 releases the fixation of the anchor cable by the claw 114, then resets this anchor cable installation equipment and conducts subsequent use. The staff applies stress to the right end of the anchor cable again and fixes it.

[0045] Embodiment 2

[0046] Based on Embodiment 1, as Figure 1 and Figure 8 shown, it further includes an anchor cable rotation mechanism. The anchor cable rotation mechanism is arranged on the right side of the support plate 104. The anchor cable rotation mechanism is used to overcome the torsion generated during the rotation of the anchor cable. The anchor cable rotation mechanism includes a second fixing plate 401, and the second fixing plate 401 is welded to the support plate 104. The second fixing plate 401 is welded with a first fixing frame 402. The first fixing frame 402 is rotatably connected with a guiding pipe 403 for guiding the anchor cable. The guiding pipe 403 drives the anchor cable to swing up and down, overcoming the torsion generated during the rotation of the anchor cable itself, and preventing the anchor cable from slipping with the claw 114 due to excessive self-torsion. The guiding pipe 403 is set to be arc-shaped for changing the moving direction of the anchor cable. The inner wall of the guiding pipe 403 is set to be a smooth surface for reducing the friction force received by the anchor cable in the guiding pipe 403. A gear ring 404 is fixedly connected to one side of the guiding pipe 403 close to the first fixing frame 402. The first fixing frame 402 is fixedly connected with a third driving motor 405 electrically connected to the control panel 103. The output shaft of the third driving motor 405 is fixedly connected with a second gear 406 meshing with the gear ring 404.

[0047] First, the staff passes the anchor cable through the guiding tube 403. The anchor cable moves along the guiding tube 403 to change the placement position of the anchor cable in the roadway, avoiding the inconvenience of installing the overly long anchor cable in the roadway. By means of the guiding tube 403, the moving direction of the anchor cable is changed, so that the end of the anchor cable moves along the roadway direction. During the movement of the moving frame 108, the control panel 103 activates the third driving motor 405. The output shaft of the third driving motor 405 drives the second gear 406 to rotate reciprocally. The second gear 406 drives the guiding tube 403 to swing reciprocally along the first fixing frame 402 through transmission with the toothed ring 404, making the reciprocating rotation angle and rotation speed of the guiding tube 403 the same as those of the rotating ring 109. The guiding tube 403 drives the anchor cable to swing up and down, overcoming the torsion generated during the rotation of the anchor cable itself and avoiding excessive self-torsion of the anchor cable from slipping with the claw 114.

[0048] As Figure 9 and Figure 10 shown, it also includes a vibration mechanism. The vibration mechanism is arranged on the left side of the moving frame 108 and is used to improve the grouting efficiency of the anchor cable hole. The vibration mechanism includes a second fixing frame 501. The second fixing frame 501 is bolted to the moving frame 108. The second fixing frame 501 is symmetrically provided with sliding grooves. A second sliding plate 502 is slidably connected in the sliding grooves of the second fixing frame 501. A through hole is provided in the middle of the second sliding plate 502. One side of the second fixing frame 501 is fixedly connected with a reciprocating expander 503 electrically connected to the control panel 103. The telescopic end of the reciprocating expander 503 is connected to the second sliding plate 502. The second sliding plate 502 quickly impacts on the anchor cable, causing the anchor cable to vibrate. During the process of grouting the anchor cable hole, the vibration of the anchor cable is utilized to increase the moving speed of the grouting material in the anchor cable hole. At the same time, the vibration generated by the anchor cable can also eliminate the air bubbles in the grouting material, enabling the grouting material to flow uniformly along the anchor cable hole to the left, avoiding uneven distribution of the grouting material in the anchor cable hole to form voids, resulting in a reduction in the reinforcement effect of the anchor cable on the rock mass.

[0049] When the claw 114 fixes the anchor cable, the end of the anchor cable passes through the through hole of the second sliding plate 502. When the claw 114 applies prestress to the anchor cable, the anchor cable is in a taut state. Subsequently, the control panel 103 activates the reciprocating expander 503. The telescopic end of the reciprocating expander 503 drives the second sliding plate 502 to move reciprocally quickly, causing the second sliding plate 502 to quickly impact on the anchor cable, making the anchor cable vibrate. During the process of grouting the anchor cable hole, the vibration of the anchor cable is utilized to increase the moving speed of the grouting material in the anchor cable hole. At the same time, the vibration generated by the anchor cable can also make the grouting material evenly distributed in the anchor cable hole and flow uniformly along the anchor cable hole to the left, avoiding uneven distribution of the grouting material in the anchor cable hole to form voids, resulting in a reduction in the reinforcement effect of the anchor cable on the rock mass.
