Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a rod changing and raising device. Background Art

[0002] As the main support form for underground projects and rock slopes, anchor rods are widely used in highway and railway tunnels and mining tunnels. With the development of anchor rod support, the forms, types and specifications of anchor rods are becoming more and more diverse. In order to obtain better support effects, the length requirements of anchor rods are also increasing, so the anchor rod holes also need to be drilled deeper.

[0003] The anchor trolley is one of the main equipment for drilling anchor holes. Due to the length of the propulsion beam and the size limitation of the equipment, the drilling depth of common anchor trolleys on the market is 2-4 meters. When deeper holes need to be drilled, several drill rods are often required to connect the holes. That is, the first drill rod is drilled with the anchor trolley, and then the second drill rod is replaced with the first one to continue drilling, and finally the third one is replaced.

[0004] Currently, bolt replacement on anchor rigs is primarily manual, a cumbersome process that requires not only lowering the boom but also repositioning the hole after the change. Furthermore, bolt replacement in tunnels is dangerous and time-consuming, delaying construction schedules and posing significant safety risks.

[0005] In addition to manual rod replacement, some anchor trolleys currently on the market use cage-type anchor rod storage for rod replacement. my country's drilling tool industry has established industry standards for anchor rods and drill rods, with tools of varying cross-sections and lengths. While these anchor rod storage systems can address the issue of continuous anchor rod installation, they cannot accommodate different lengths of propeller beams or anchor rods in the complex and ever-changing tunnel field operating environment. This results in a single operating method and poor versatility and applicability of anchor rod changers. Summary of the Invention

[0052] Example 1

[0053] like Figure 1-6As shown in the embodiment, a rod-changing and rod-raising device is disclosed, which mainly includes a rod-raising mechanism and a rod-changing mechanism. The rod-raising mechanism includes two rod-raising devices 1, which are hinged to the side of the propulsion beam 2 at intervals along the length direction of the propulsion beam 2, and the two rod-raising devices 1 are detachably connected to the propulsion beam 2, that is, the spacing between the two rod-raising devices 1 can be adaptively adjusted according to the length of the anchor rod 3 to adapt to anchor rods 3 of various length specifications. Both rod-raising devices 1 have a rod-mounting structure for respectively accommodating the head end and the tail end of the anchor rod 3, that is, the two ends of the anchor rod 3 can be supported and mounted on the two rod-raising devices 1, and the middle part is suspended, wherein the same rod-raising mechanism can accommodate and support one or more anchor rods 3.

[0054] The rod-changing mechanism is located on the propulsion beam 2 or the upper rod mechanism, and the rod-changing mechanism has a supporting structure capable of supporting the anchor rods 3. That is, the anchor rods 3 are supported by the upper rod mechanism while also supported by the rod-changing mechanism. The rod-changing mechanism has a rotational and / or translational travel relative to the upper rod mechanism. During the process of rotation and / or translation relative to the upper rod mechanism, the rod-changing mechanism can deliver the anchor rods 3 supported by the upper rod mechanism one by one out of the rod-loading structure, so that the anchor rods 3 fall onto the connecting station on the propulsion beam 2. The rock drill on the propulsion beam 2 can then be pushed forward to connect with the anchor rods 3 at the connecting station, thus realizing the rod-changing and upper rod function.

[0055] In this embodiment, one end of the rod-lifting device 1 is hinged to the side of the propulsion beam 2, and the rod-mounting structure is an annular groove 101 provided at the other end of the rod-lifting device 1. A notch 102 is provided on the side of the annular groove 101 for the anchor rod 3 to enter and exit the annular groove 101, that is, Figure 4 and Figure 5 As shown. Specifically, the rod lifter 1 includes: a base frame 4, a side baffle 5 and a curved panel 6 with an arc-shaped structure. Among them, one end of the base frame 4 is hinged to the side of the propulsion beam 2, and the curved panel 6 is fixedly connected to the other end of the base frame 4 by welding. The annular groove 101 is located between the base frame 4 and the curved panel 6, and the notch 102 is opened in the middle of the curved panel 6. The side baffle 5 is welded and fixed to the base frame 4 and the curved panel 6, and the side baffle 5 covers one side of the annular groove 101. The anchor rod 3 extends into the annular groove 101 through the other side of the annular groove 101, that is, the anchor rod 3 is located between the two side baffles 5 on the two rod lifters 1 to prevent the end of the anchor rod 3 from being subjected to additional impact force while preventing the anchor rod 3 from sliding out of the side of the annular groove 101.

[0056] More specifically, the rod-changing and rod-lifting device in this embodiment also includes a rod-lifting cylinder 7. A mounting seat 8 is provided at the position of the rod-lifting device 1 on the side of the propulsion beam 2 by welding or bolt connection. The mounting seat 8 has a first hinge hole and a second hinge hole, and the base frame 4 has a third hinge hole and a fourth hinge hole. The base frame 4 and the mounting seat 8 are hinged by the cooperation of the first pin 9 with the first hinge hole and the third hinge hole. The fixed end of the rod-lifting cylinder 7 is hinged to the second hinge hole of the mounting seat 8 through the second pin 10, and the telescopic end of the rod-lifting cylinder 7 is hinged to the fourth hinge hole of the base frame 4 through the third pin 11. The two rod-lifting devices 1 are rotated around the first hinge hole on the support by pushing out and retracting the piston rod of the rod-lifting cylinder 7. Then, the notches 102 on the two rod-lifting devices 1 can be rotated to the connection position of the propulsion beam 2. During this process, the rod-changing mechanism is kept stationary, that is, during the rotation of the rod-lifting device 1, the position of the anchor rod 3 in the annular groove 101 remains relatively stationary.

[0057] In this embodiment, the rod-changing mechanism has two implementation modes, specifically:

[0058] In a first embodiment of the rod-changing mechanism, the rod-changing mechanism includes a rod-changing driver, a connecting shaft 12, and a holder 13 fixedly mounted on the connecting shaft 12. The holder 13 is a circular pancake-shaped structure and is fixedly mounted on the connecting shaft 12 by welding or key connection. The two ends of the connecting shaft 12 are rotatably connected to the two rod-lifting devices 1 by a clearance fit or a bearing fit. The holder 13 is located between the two rod-lifting devices 1. The supporting structure is a C-shaped bayonet 1301 provided on the side of the holder 13. The C-shaped bayonet 1301 can be used to store the anchor rod 3. The rod-changing driver includes a rod-changing cylinder 14 and a connecting plate 15 provided on any rod-lifting device 1. One end of the rod-changing cylinder 14 is hinged to the corresponding rod-lifting device 1 through a fourth pin 16. The other end of the rod-changing cylinder 14 is hinged to one end of the connecting plate 15 through a fifth pin 17. The other end of the connecting plate 15 is fixedly connected to the connecting shaft 12 through a flat key. The extension and contraction of the rod-changing cylinder 14 can drive the connecting shaft 12 to rotate, and thus drive the anchor rod 3 held by the holding device 13 to rotate in the annular groove 101. Figure 4 and Figure 6 For example, the two C-shaped bayonet holes 1301 on the supporter 13 respectively hold an anchor rod 3. When the rod-changing cylinder 14 works and the piston rod is pushed out, the anchor rod 3 fixed on the C-shaped bayonet hole 1301 of the supporter 1 is driven by the supporter 13 to rotate in the annular groove 101 of the rod-lifting device 1, and stops when it rotates to the notch 102 of the annular groove 101. At this time, the state is Figure 6As shown, the rod-lifting cylinder 7 then works, the piston rod is pushed out, the rod-lifting device 1 rotates, and the anchor rod 3 is turned to the connection position of the central axis of the rock drill. The rock drill is pushed forward to connect with the anchor rod 3, thereby realizing the rod-changing and rod-lifting function. When drilling is completed, the anchor rod 3 can also be recovered by retracting the anchor rod 3 to the annular groove 101 of the rod-lifting device 1 and the C-shaped bayonet 1301 of the holder 13.

[0059] Preferably, the rod-changing driver can be a driving motor, which is fixedly mounted on the side baffle 5 , and the driving end is connected to the connecting shaft 12 to directly drive the connecting shaft 12 to rotate.

[0060] Preferably, there are two support grips 13, one of which is located between the two rod lifters 1 and close to one of the rod lifters 1, and the other support grip 13 is located between the two rod lifters 1 and close to the other rod lifter 1, so as to maintain the consistency of the front and rear ends of the anchor rod 3 during the rod changing process.

[0061] In the second embodiment of the rod changing mechanism, the rod changing mechanism is a clamp provided on the side of the propulsion beam 2, and the supporting structure is a clamp 22 provided on the clamp. The clamp has a first stroke of rotation and / or translation on the propulsion beam 2, and the clamp has a second stroke of rotation relative to the upper rod device 1. Specifically, the anchor rod changing and upper rod device also includes a first driving member and a second driving member, and both the first driving member and the second driving member can adopt oil cylinders. A rotating frame is hinged at the position of the clamp on the side of the propulsion beam 2, and the clamp is hinged on the rotating frame. The hinge method is the same as the above-mentioned mounting seat 8 and base frame 4, so it will not be described in detail. One end of the first driving member is hinged to the side of the propulsion beam 2, and the other end is hinged to the mounting seat 8; one end of the second driving member is hinged to the mounting seat 8, and the other end is hinged to the clamp. When the first drive is activated and the second drive is not activated, the clamp can rotate along with the turret on the side of the propulsion beam 2, thus achieving the first stroke of the clamp; when the upper rod cylinder 7 and the first drive are both not activated, the clamp can rotate alone on the turret, thus achieving the second stroke of the clamp. The upper rod changing process is as follows: the second drive is kept stationary, and the upper rod cylinder 7 and the first drive work synchronously, so that the upper rod device 1 and the turret rotate synchronously until the notch 102 on the upper rod device 1 coincides with the connection position on the propulsion beam 2, then the upper rod cylinder 7 and the first drive are kept stationary, and the second drive is activated, driving the anchor rod 3 fixed on its clamp 22 to rotate in the annular groove 101 of the upper rod device 1, and stopping when it rotates to the notch 102 of the annular groove 101. The rock drill can be pushed forward to connect with the anchor rod 3, and then the clamp is controlled to open the clamp 22, and the upper rod device 1 and the turret are controlled to reset. At this point, the rod changing and rod raising function is realized. When drilling is completed, the anchor rod 3 can also be recovered by retracting the anchor rod 3 to the annular groove 101 of the rod raising device 1 and the clamping mouth 22 of the clamp.

[0062] refer to Figure 7 The clamp includes a pivot 18, a first clamp body 19, a second clamp body 20, and a clamping cylinder 21. Specifically, the first clamp body 19 is hinged on the rotating frame, and the first clamp body 19 and the pivot 18 are fixedly matched by welding or key connection, while the second clamp body 20 is sleeved on the pivot 18 by clearance fit or bearing fit. The first clamp body 19 is provided with at least one first jaw, and the second clamp body 20 is provided with at least one second jaw, and the first jaw and the second jaw correspond one-to-one. The first jaw and the corresponding second jaw constitute a clamp jaw 22. The fixed end of the clamping cylinder 21 is fixedly connected to the first clamp body 19 by a fixing device such as a bolt, and the telescopic end of the clamping cylinder 21 is hinged to the second clamp body 20. When the clamping cylinder 21 performs telescopic movement, since the first clamp body 19 is rigidly connected to the pivot 18, the second clamp body 20 can rotate relative to the first clamp body 19. Driven by the clamping oil cylinder 21 , the first jaw and the corresponding second jaw move closer to or farther away from each other, thereby switching the jaws 22 between open and closed states, thereby achieving a loose or clamped state for the anchor rod 3 .

[0063] Preferably, there are two clamps, one of which is located between the two rod lifters 1 and close to one of the rod lifters 1, and the other clamp is located between the two rod lifters 1 and close to the other rod lifter 1, so as to maintain the consistency of the front and rear ends of the anchor rod 3 during the rod changing process.

[0064] It should be noted that although this embodiment uses a cylinder as the driving component, it is not limited to a cylinder, nor is it limited to the above-mentioned installation location. It only needs to be able to drive the corresponding component to rotate. For example, a motor and a reducer can be used to drive the component to rotate. Here, the motor and reducer can be installed on the corresponding component or arranged separately via a bracket.

[0065] Example 2

[0066] like Figure 8-9 As shown in the embodiment, a rod-changing and rod-lifting device is disclosed, which mainly includes a rod-lifting mechanism and a rod-changing mechanism. The rod-lifting mechanism includes two rod-lifters 1, which are hinged to the side of the propulsion beam 2 at intervals along the length direction of the propulsion beam 2, and the two rod-lifters 1 are detachably connected to the propulsion beam 2, that is, the spacing between the two rod-lifters 1 can be adaptively adjusted according to the length of the anchor rod 3 to adapt to anchor rods 3 of various length specifications. Both rod-lifters 1 have a rod-mounting structure for respectively accommodating the head end and the tail end of the anchor rod 3, that is, the two ends of the anchor rod 3 can be supported and mounted on the two rod-lifters 1, and the middle part is suspended, wherein the same rod-lifting mechanism can accommodate and support one anchor rod 3.

[0067] One end of the rod lifter 1 is hinged to the side of the propulsion beam 2 and is also driven by the rod lifter cylinder 7. The hinge and cylinder connection method are the same as those of the base frame in Example 1, so they will not be described in detail. The rod mounting structure is a first curved plate 23 provided at the other end of the rod lifter 1, with the curved opening of the first curved plate 23 facing downward.

[0068] The rod changing mechanism includes a rod changing cylinder 14 and a second curved plate 24. One end of the second curved plate 24 is hinged to the rod lifter 1 through a sixth pin shaft 25, and the other end is an upward curved opening. The curved opening of the second curved plate 24 is located below the curved opening of the first curved plate 23. An anchor rod 3 can be clamped between the two, wherein the supporting structure is the curved opening of the second curved plate 24.

[0069] One end of the rod-changing cylinder 14 is hinged to the rod-lifting device 1, and the other end is hinged to the bottom of the second curved plate 24. By extending and retracting the rod-changing cylinder 14, the second curved plate 24 can be driven to rotate around the sixth pin 25, thereby tightening or loosening the anchor rod 3 between the first curved plate 23 and the second curved plate 24. The rod-lifting and rod-changing process is as follows: first, the rod-changing cylinder 14 is kept stationary to clamp the anchor rod 3 between the first curved plate 23 and the second curved plate 24; then, the rod-lifting cylinder 7 is activated to cause the two rod-lifting devices 1 to rotate synchronously until the anchor rod 3 between the first curved plate 23 and the second curved plate 24 coincides with the connection position on the propulsion beam 2; then, the rod-lifting cylinder 7 is kept stationary and the rod-changing cylinder 14 is activated to rotate the second curved plate 24 downward, releasing the anchor rod 3 between the first curved plate 23 and the second curved plate 24; finally, the rod-lifting device 1 is controlled to reset. At this point, the rod changing and rod raising function is realized. When drilling is completed, the anchor rod 3 can also be recovered by retracting the anchor rod 3 into the annular groove of the rod raising device 1 and the clamping mouth of the clamp.

[0070] As a preferred embodiment, a set of rod-lifting mechanisms can be provided on both sides of the propulsion beam 2, so that rod-lifting can be achieved on both sides. Not only does it not require rod replacement and has a high fault tolerance rate, but even if a fault occurs on one side, it will not affect the rod-lifting work on the other side.

[0071] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
