Description

Technical Field

[0001] The utility model relates to the technical field of mine support auxiliary equipment, and particularly relates to an automatic cable anchor feeder for roof support. Background Technique

[0002] During the tunneling operation, while the coal shearer excavates the roadway, it is also necessary to support the roof. The main support methods for the roof are bolt support and cable anchor support. Since the bolt is relatively short in length, a professional bolt machine operator can complete the bolt support alone. However, the cable anchor itself is relatively long (about 8m). When carrying out cable anchor support, usually two bolt machine operators cooperate to complete it. The specific cooperation method is that one bolt machine operator operates the equipment to complete the drilling operation. Subsequently, another bolt machine operator stands on the roof of the coal shearer. First, resin (usually three pieces) is loaded into the drill hole. Then, the bolt machine operator under the roof hands the cable anchor to the operator above. The operator holds the resin at the drill hole with the left hand and receives the cable anchor with the other hand, and then pushes the cable anchor and the resin together into the drill hole (often there will also be a phenomenon that the resin is scratched because the cable anchor and the resin are not aligned). After the exposed cable anchor reaches a certain length, the operator under the roof inserts the stirrer into the bottom of the cable anchor, and then installs the stirrer on the drill rig, and uses the drill rig to push the cable anchor to move upward continuously until the cable anchor reaches the standard of the exposed length and then stirs.

[0003] In the above process, when the operator on the roof manually pushes the cable anchor into the drill hole, due to the long length of the cable anchor, as the cable anchor continuously enters the drill hole, it will be more and more laborious for the operator to manually push, and it is also extremely unsafe, and the labor intensity of the workers is high. Summary of the Utility Model

[0004] The utility model provides an automatic cable anchor feeder for roof support to improve the convenience of cable anchor installation and reduce the installation difficulty.

Any support plate has two relative guide slots, and the two guide slots extend radially along the shell. The two rotating shafts respectively pass through the two guide slots of the same support plate. The articulated frame is located between the two guide slots. Any rotating shaft is hinged to the articulated frame through the articulated rod. The push-pull rod is arranged at the bottom of the articulated frame and passes through the bottom of the shell. The push-pull rod drives the articulated frame to be raised and lowered to drive the rotating shaft to slide in the corresponding guide slot and make the extrusion wheel enter and exit the corresponding avoidance port.

Thereafter, the operator inserts the anchor cable from the end of the feeding tube protruding from the bottom of the shell into the feeding channel, and the anchor cable moves upward in the feeding channel until it passes through the one-way limit piece and pushes the resin to slide upward together, thereby realizing the push installation of the anchor cable.

[0017] In this way, the feeding channel is fixed by the detachable installation of the shell and the insertion of the embedded tube, and the limited installation of the resin is achieved by the setting of the embedded tube and the one-way limit piece, avoiding the situation in the prior art that at least two operators are required to install the anchor cable.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Such as Figures 1 to 7As shown, an embodiment of the utility model provides an automatic anchor cable loader for roof support, including a loading shell and a one-way limiter 9, the loading shell includes a shell 1 and a loading tube and an embedded tube 2 coaxially arranged on the shell 1, the shell 1 is detachably installed under the roof, the embedded tube 2 is fixedly arranged on the top of the shell 1 and is pluggable in the anchor cable hole, the cavity of the embedded tube 2 is connected with the cavity of the shell 1, the loading tube at least partially penetrates into the shell 1 from the bottom of the shell 1 and is connected to the bottom of the shell 1, the inner diameter of the loading tube is adapted to the inner diameter of the embedded tube 2 and constitutes a loading channel; the one-way limiter 9 is arranged in the embedded tube 2 and divides the cavity in the embedded tube into an upper cavity and a lower cavity, the one-way limiter 9 is used to limit the movement of resin entering the upper cavity from the opening on the side of the embedded tube 2 away from the shell 1 to the lower cavity, the direction of the lower cavity toward the upper cavity is the loading direction of the anchor cable, the anchor cable moves along the loading direction and can pass through the one-way limiter 9.

[0030] In this embodiment, when it is necessary to install the anchor cable, the operator first inserts the resin into the drilled anchor cable hole, and then the operator inserts the embedded tube 2 into the drilled anchor cable hole and installs the shell 1 under the top plate. The resin penetrates into the embedded tube 2 from the opening at one end of the embedded tube 2 away from the shell 1 and is stopped in the area above the feeding channel by the one-way limiter 9, completing the installation of the resin and the feeding shell. Thereafter, the operator inserts the anchor cable from the end of the feeding tube protruding from the bottom of the shell 1 into the feeding channel, and the anchor cable moves upward in the feeding channel until it passes through the one-way limiter 9 and pushes the resin to slide upward together, thereby realizing the push installation of the anchor cable.

[0031] In this way, the feeding channel is fixed by the detachable installation of the shell 1 and the insertion of the embedded tube 2, and the limited installation of the resin is achieved by the setting of the embedded tube 2 and the one-way limit member 9, avoiding the situation in the prior art that at least two operators are required to install the anchor cable. The installation of the anchor cable can be completed by one person, which improves the convenience of installation and reduces the installation difficulty and the labor intensity of the operator. At the same time, it avoids the safety problems that may occur when the anchor cable is installed by manually supporting the anchor cable or the resin in the prior art, which is beneficial to ensuring the construction safety of the workers.

[0032] On the other hand, the feeding tube and the embedded tube 2 are coaxially arranged to achieve coaxial contact between the anchor cable and the resin during installation, avoiding the situation where the resin is easily squeezed and rotten due to uneven force when the anchor cable and the resin are not coaxial. This not only provides convenience for operators, but also eliminates the worry of the resin being squeezed and damaged, which is conducive to improving the installation efficiency and reliability of the anchor cable. It can be understood that the number of resins can be adjusted according to actual conditions, and in this embodiment, there are 3 resins.

[0033] It should be noted that the principle of the one-way limiter in this embodiment is the same as that of the one-way valve.

[0034] likeFigures 3 to 5 As shown, the automatic feeding device for the anchor cable used for roof support further includes an anchor cable driving part arranged in the housing 1. The feeding pipe has two oppositely arranged avoidance openings 8 on the side wall inside the housing 1. The anchor cable driving part includes two pressing wheels 10 respectively corresponding to the two avoidance openings 8. Part of the pressing wheel 10 extends into the cavity of the feeding pipe from the avoidance opening 8 and abuts against the outer periphery of the anchor cable in the feeding channel. The two pressing wheels 10 are rotatably arranged to drive the anchor cable in the feeding channel to move towards the drilling hole along the feeding direction.

[0035] In this embodiment, one side of the two pressing wheels 10 close to each other can respectively extend into the inner embedded pipe 2 from the two avoidance openings 8 and press the internal anchor cable. Through the frictional extrusion of the two pressing wheels 10 on the anchor cable extending into the feeding channel and the rotation of the two pressing wheels 10, the rotational drive of the anchor cable is realized, and then the anchor cable is driven to move into the drilling hole. It can be understood that the rotation directions of the two pressing wheels 10 are opposite to ensure the reliability of the drive of the anchor cable. Such a setting is conducive to realizing the automatic filling of the anchor cable, reducing labor and improving the installation efficiency, and at the same time is conducive to ensuring the construction safety of the operator.

[0036] Specifically, the anchor cable driving part further includes a rotating shaft 11, a support plate group and a driving component. There are two rotating shafts 11. The two pressing wheels 10 are respectively fixedly sleeved on the two rotating shafts 11. The support plate group includes support plates 12 distributed on both sides of the feeding pipe along the extension direction of the rotating shaft 11. The two support plates 12 respectively support the two ends of the rotating shaft 11. The driving component is arranged on one side of the support plate group and is drivingly connected to the ends of the two rotating shafts 11 on the same side to drive the two pressing wheels 10 to rotate simultaneously. Such a setting realizes the simultaneous drive of the two rotating shafts 11 through one driving component, and then realizes the simultaneous drive of the two pressing wheels 10, which is conducive to ensuring the reliability and stability of the pressing wheels 10 for the rotational drive of the anchor cable by extrusion.

[0037] As Figure 5 shown, the driving component includes a double-shaft motor 16, a first worm 17, a second worm 18, a first worm gear 19 and a second worm gear 20. The first worm 17 and the second worm 18 are coaxial and located on both sides of the double-shaft motor 16. The two driving shafts of the double-shaft motor 16 are respectively drivingly connected to the first worm 17 and the second worm 18. The helix directions of the first worm 17 and the second worm 18 are opposite. The first worm gear 19 and the second worm gear 20 are respectively fixedly sleeved on the ends of the rotating shaft 11. The first worm gear 19 meshes with the first worm 17, and the second worm gear 20 meshes with the second worm 18. Such a setting facilitates the setting of the driving component and the rotational drive of the two rotating shafts 11. Among them, the driving component is arranged on one side of the support plate group and is supported in the housing 1 by a support member such as a support seat.

[0038] As Figure 5 and Figure 6As shown in the figure, the automatic feeding device for anchor cables used in roof support further includes an adjusting part. The adjusting part includes a hinge frame 21, a hinge rod 15 and a push-pull rod 6. Each support plate 12 has two opposite guiding chutes 13. The two guiding chutes 13 extend along the radial direction of the housing 1. The two rotating shafts 11 respectively pass through the two guiding chutes 13 of the same support plate 12. The hinge frame 21 is located between the two guiding chutes 13. Any one of the rotating shafts 11 is hinged to the hinge frame 21 through the hinge rod 15. The push-pull rod 6 is arranged at the bottom of the hinge frame 21 and passes through the bottom of the housing 1. The push-pull rod 6 drives the hinge frame 21 to be arranged in a liftable manner, so as to drive the rotating shaft 11 to slide in the corresponding guiding chute 13 and make the pressing wheel 10 enter and exit the corresponding avoidance opening 8. The hinge frame 21 is in a stop fit with the bottom wall of the cavity of the housing 1. Specifically, the hinge frame 21 in this embodiment is a U-shaped frame.

[0039] In this embodiment, the operator can adjust the position of the pressing wheel 10 by pulling the push-pull rod 6, so as to ensure the reliability of the pressing of the anchor cable in the feeding channel by the pressing wheel 10. At the same time, it can also avoid the situation that the anchor cable cannot extend in when the radial dimension of the anchor cable is larger than the gap between the two pressing wheels 10. Specifically, the guiding chute 13 is a strip-shaped groove parallel to the radial direction of the housing 1 and perpendicular to the axial direction of the rotating shaft 11. The operator drives the hinge frame 21 to lift in the housing 1 by pulling the push-pull rod 6. Due to the limiting cooperation between the rotating shaft 11 and the guiding chute 13, the rotating shaft 11 can only slide along the extending direction of the guiding chute 13. Combining that each rotating shaft 11 is hinged to the hinge frame 21 through the hinge rod 15, the rotating shaft 11 will move along the guiding chute 13 as the hinge frame 21 lifts and the two rotating shafts 11 will move relatively, thereby driving the two pressing wheels 10 to approach or move away from each other relatively. Such a setting ensures the reliability of the pressing and driving of the anchor cable by the pressing wheel 10, and at the same time ensures the reliability of the installation of the anchor cable.

[0040] As Figure 7 shown in the figure, the adjusting part further includes a stop plate 22 and a nut member 23. The stop plate 22 is arranged at one end of the push-pull rod 6 located outside the housing 1. The stop plate 22 is in a stop fit with the outer wall of the bottom of the housing 1. The outer periphery of the end of the push-pull rod 6 close to the hinge frame 21 has an external thread 24. The setting height of the external thread 24 is greater than the thickness of the bottom of the housing 1. The nut member 23 is sleeved on the outer periphery of the push-pull rod 6 and is located between the outer wall of the bottom of the housing 1 and the stop plate 22. The nut member 23 is detachably threadedly connected to the external thread 24.

[0041] Such a setting realizes the limitation of the end of the push-pull rod 6 through the stop plate 22, avoiding the situation that the push-pull rod 6 completely extends into the housing 1. The pressing of the hinge frame 21 is realized through the nut member 23, avoiding the situation that the hinge frame 21 and the push-pull rod 6 will move by themselves, and ensuring the reliability and stability of the position adjustment of the pressing wheel 10.

[0042] Specifically, the adjusting part in this embodiment has an initial state and a squeezing state. When the adjusting part is in the initial state, the two squeezing wheels 10 are located on both sides of the feeding pipe and are spaced from the feeding pipe, avoiding the situation that the two squeezing wheels 10 extend into the feeding pipe and cause the gap for installing the anchor cable to become smaller, thus affecting the passing of the anchor cable through the connecting pipe 7. The push-pull rod 6 extends into the housing 1 and is stopped and limited outside the bottom of the housing 1 by the stop baffle 22, preventing the push-pull rod 6 from entering the housing 1 completely and making it impossible to pull it. The two hinge rods 15 are on the same straight line and are 180°. After the operator fixes the housing 1 of the feeding shell on the roof and inserts the head of the anchor cable into the feeding channel corresponding to the positions of the two avoidance openings 8, the operator can pull the push-pull rod 6 downward. The push-pull rod 6 drives the hinge frame 21 and the two hinge rods 15 to move, causing the angle between the two hinge rods 15 to continuously decrease and rotate towards each other with the hinge points of the two with the hinge frame 21 as the rotation centers, thereby driving the two rotating shafts 11 to slide towards each other, so as to drive the two squeezing wheels 10 to extend into the corresponding two avoidance openings 8 and squeeze the anchor cable in the feeding channel. When the push-pull rod 6 is pulled downward until the external thread 24 at its top protrudes outside the bottom of the housing 1, the operator can adjust the nut member 23 so that the nut member 23 is threadedly connected to it. Then, the nut member 23 can be twisted by hand or a wrench, and the push-pull rod 6 will continue to move downward as the threaded connection deepens until the two rotating shafts 11 slide relatively close to the ends of the two guiding chutes 13 on the side where they are close to each other. At this time, the distance between the two squeezing wheels 10 is the shortest, and the squeezing force on the anchor cable is the largest. The nut member 23 is tightened outside the bottom of the housing 1 to keep the two squeezing wheels 10 stationary at this position, realizing the conversion of the adjusting part from the initial state to the squeezing state.

[0043] Preferably, when the two rotating shafts 11 slide relatively close to the ends of the two guiding chutes 13 on the side where they are close to each other and the nut member 23 is tightened outside the bottom of the housing 1, the bottom of the hinge frame 21 abuts against the bottom wall of the cavity of the housing 1.

[0044] Further, in this embodiment, the extension directions of the dual-axis motor 16, the first worm 17, and the second worm 18 are parallel to the extension direction of the guiding chute 13. During the process of the two rotating shafts 11 sliding towards each other in this embodiment, since the dual-axis motor 16, the first worm 17, and the second worm 18 do not rotate, the first worm gear 19 will cause the rotating shaft 11 to roll and move along the extension direction of the guiding chute 13 rather than simply move due to its meshing with the first worm 17. The same applies to the second worm gear 20, and the first worm gear 19 and the second worm gear 20 roll relatively closer. After the rotating shaft 11 rolls and moves to the limit position, the adjusting part switches to the extrusion state. At this time, the position of the rotating shaft 11 cannot roll along the guiding chute 13 but can only rotate itself because the push rod 6 is restricted by the nut member 23. At this time, the dual-axis motor 16 can be driven to rotate to simultaneously drive the first worm gear 19 and the second worm gear 20 to rotate, and make the two groups of rotating shafts 11 and the extrusion wheels 10 rotate relative to each other, realizing the driving of the cable anchor extruded between the two extrusion wheels 10. It can be understood that since the rotation directions of the rotating shafts on both sides of the dual-axis motor 16 are the same, the helix directions of the first worm 17 and the second worm 18 in this application are kept opposite, so the rotation directions of the second worm 18 and the first worm gear 19 are also opposite, and in this way, the extrusion wheels 10 distributed on both sides of the cable anchor can be driven to slide upward by keeping different rotation directions.

[0045] As Figures 2 to 6 shown, there are at least two adjusting parts, and multiple adjusting parts are spaced apart along the extension direction of the rotating shaft 11 on both sides of the support plate group.

[0046] In this embodiment, there are two adjusting parts, and the two adjusting parts are respectively arranged on both sides of the support plate group. With such an arrangement, the supporting effect and the movement guiding effect on the two rotating shafts 11 are improved, ensuring the reliability and stability of the movement of the rotating shaft 11 and the extrusion wheel 10 in the housing 1.

[0047] As Figure 1 and Figure 2 shown, the cable anchor automatic feeding device for roof support further includes a plurality of hanging components. The plurality of hanging components are spaced apart along the circumferential direction of the housing 1. The hanging component has a hanging end to detachably hang the housing 1 under the roof and make the top of the housing 1 closely attached to the roof. With such an arrangement, it is convenient to disassemble and assemble the housing 1, and thus convenient for the fixed installation of the feeding channel, which is beneficial to improving the installation efficiency and reliability of the cable anchor.

[0048] Specifically, the hanging assembly includes a chain 3 and a hook member 4 connected to each other. The end of the chain 3 away from the hook member 4 is fixedly connected to the outer wall of the housing 1, and the hook of the hook member 4 away from the end of the chain 3 forms a hanging end. In this embodiment, there are four hanging assemblies, and the four hanging assemblies are evenly distributed along the circumference of the housing 1. The housing 1 is hung on the steel mesh of the top plate through the four hook members 4. The four chains 3 are straightened to make the housing 1 close to the bottom of the top plate. At this time, the operator can completely release his hands. The operator can independently align the anchor cable with the feeding pipe and insert it and drive the anchor cable to move upward inside the feeding channel.

[0049] like Figure 2 and Figure 3 As shown, the feeding pipe partially extends into the shell 1, the part of the feeding pipe extending into the shell 1 is the connecting pipe 7, the part of the feeding pipe protruding from the shell 1 is the guide pipe 5, the end of the connecting pipe 7 abuts against the top wall of the shell 1 cavity and docks with the embedded tube 2, and the sum of the height of the guide pipe 5 and the thickness of the shell 1 is the exposed length of the anchor cable.

[0050] This embodiment controls the thickness of the shell 1 and the length of the guide tube 5 and makes the sum of the two values just equal to the exposed length of the anchor cable, ensuring that the exposed lengths of all anchor cables are consistent and no longer rely on the workers' experience to control, which is conducive to the standardization of anchor cable support.

[0051] Specifically, when the operator operates the drilling rig to push the anchor cable upward, the operator stops pushing the anchor cable upward when the agitator moves upward to the bottom of the guide tube 5. At this time, the drilling rig starts to rotate and drives the agitator to stir and anchor the anchor cable. In this way, the exposed length of the anchor cable can be well controlled, and workers do not need to rely on their own experience to judge. At the same time, it can also ensure that the exposed lengths of all anchor cables are consistent.

[0052] Preferably, the connecting pipe 7 in this embodiment is integrally formed inside the shell 1, and the embedded pipe 2 and the guide pipe 5 are respectively welded to the top and bottom of the shell 1 and coaxially communicated with the connecting pipe 7 to form a feeding channel. Furthermore, the inner diameters of the connecting pipe 7, the embedded pipe 2 and the guide pipe 5 are consistent and slightly larger than the diameter of the anchor cable.

[0053] In summary, the present utility model provides an automatic loader for anchor cables used in roof support, which includes a cylindrical housing 1. A connecting pipe 7 is formed at the center inside the housing 1. An embedded pipe 2 communicating with the connecting pipe 7 is welded to the top of the housing 1, and a guiding pipe 5 communicating with the connecting pipe 7 is welded to the bottom. The inner diameters of the connecting pipe 7, the embedded pipe 2, and the guiding pipe 5 are the same and slightly larger than the diameter of the anchor cable. Four chains 3 are connected to the periphery of the housing 1, and a hook member 4 is connected to the end of each chain 3. Before using the automatic loader for anchor cables used in roof support, the operator of the rock bolt machine has already completed the drilling operation. Another operator on the ceiling loads three resins into the anchor cable hole, and then inserts the embedded pipe 2 at the top of the housing 1 into the drilled anchor cable hole. Since a one-way limiting member 9 is installed in the middle of the inner part of the embedded pipe 2, the three resins can be kept stable under the supporting action of the one-way limiting member 9. Then, the four chains 3 are straightened and hung on the steel mesh of the roof through the hook members 4, so that the whole loader can "adhere" to the roof. At this time, the operator can completely release both hands. After the operator below the ceiling hands up the anchor cable, the operator above can directly insert it into the guiding pipe 5. The anchor cable moves upward inside the loader until it passes through the one-way limiting member 9 and then slides upward against the three resins. Since the resin and the anchor cable are coaxial and concentric inside the embedded pipe 2, the situation of squeezing and damaging the resin due to the non-concentricity of the anchor cable and the resin can be avoided. During the process of loading the anchor cable, the operator can adjust the positions of the two pressing wheels 10 by pulling and pushing the push rod 6, so that the two pressing wheels 10 press the anchor cable, and drive the two pressing wheels 10 to rotate and drive the anchor cable to rise along the loading direction in the loading channel under the drive of the double-shaft motor.
