Description

Technical Field

[0001] The invention belongs to the technical field of anchor support, and in particular relates to an anchor magazine and an anchor drilling rig. Background Art

[0002] With the continuous improvement of the intelligence level of coal mines and the continuous promotion of technologies such as intelligent rapid excavation, the speed of mine excavation has been greatly improved, and the level of intelligent excavation has also been greatly improved. As one of the construction processes that consumes the longest man-hours in the excavation process, bolt support construction has reduced the impact of bolt support construction on the efficiency of tunnel excavation to a certain extent by adopting a large number of bolt drills in parallel and some bolts lagging support. However, with the use of a large number of bolt drills, the contradiction between the small number of people in coal mines and the large number of equipment to be operated has become prominent again. Some coal mine underground excavation teams have repeatedly encountered the problem of a large number of equipment and a serious shortage of operators.

[0003] In the existing automatic anchor drilling rigs, single-cycle automatic anchor drilling rigs and multi-cycle automatic anchor drilling rigs are generally used to supplement anchor rods. In these two types of anchor drilling rigs, anchor rods and other supporting materials are stored in the anchor rod bin. In order to keep the anchor rods fixed reliably in the anchor rod bin, U-shaped clamps and other forms are often used to clamp and fix the anchor rods, and trays and other forms are used at the lower end of the anchor rods to prevent the anchor rods from falling from the anchor rod bin under the influence of mechanical vibrations. In the process of loading the anchor rods from the anchor rod bin to the anchor box, two sets of manipulators in the form of grippers are generally used at the same time to clamp and remove the anchor rods from the anchor rod bin, and then move the grippers to the axis position of the anchor box, wait for the anchor box to rotate and rise, and align and engage with the nut at the tail of the anchor rod, and drive the anchor rod to rise a certain distance to ensure that the anchor rod and the anchor box are reliably engaged. Only then can the manipulator retreat to avoid the operating space of the anchor box. During the process of installing the above-mentioned anchor rod to the anchor box, when the robot clamps the anchor rod, the anchor box will cause severe rotational friction between the anchor rod and the robot gripper. At the same time, the anchor rod will also slip seriously in the axial direction with the robot gripper under the push of the anchor box, causing serious wear of the robot gripper. After a period of use, its reliability will be seriously reduced. Summary of the invention

[0038] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0040] Reference Figures 1 to 6 As shown, the first aspect of this embodiment provides an anchor bar warehouse, including a swing assembly, a frame 3, a limit assembly 4 and two sets of push assemblies 5, the swing assembly is used to connect with the anchor drilling rig body, the frame 3 includes two sets of slideway assemblies 3.1 and a frame assembly 3.2, the two sets of slideway assemblies 3.1 are respectively arranged at both ends of the frame assembly 3.2, the slideway assembly 3.1 is hingedly connected to the swing assembly and can move relative to the swing assembly, the two sets of push assemblies 5 are respectively slidably arranged in the two sets of slideway assemblies 3.1, and can clamp the anchor 14; wherein the limit assembly 4 is arranged at the top of the frame assembly 3.2 The limit assembly 4 comprises two clamping arms 4.2 and four conical rollers 4.8. The two clamping arms 4.2 are cross-hinged and connected. The clamping arms 4.2 comprise a clamping rod 4.2.1 and a clamping head 4.2.2. The four conical rollers 4.8 are divided into two groups and are symmetrically and movably arranged on the two clamping heads 4.2.2. A clamping space for clamping the anchor rod 14 is formed between the four conical rollers 4.8. The anchor rod 14 passes through the clamping space and moves upward along the extension direction of the frame assembly 3.2. The clamping space generates resistance to the anchor rod 14 when it moves downward along the extension direction of the frame assembly 3.2.

[0041] Specifically, the frame assembly 3.2 is welded with profiles, the slide assembly 3.1 and the frame assembly 3.2 are welded into an integrated structure, the frame 3 can rotate relative to the swing assembly, and the swing assembly is used to connect with the anchor drilling rig body, that is, the anchor bar bin as a whole can rotate relative to the anchor drilling rig body, the push assembly 5 can slide along the extension direction of the slide assembly 3.1, and can clamp the anchor rod 14, so as to drive the anchor rod 14 to move, so as to change the working state of the anchor rod 14, and by arranging a limit assembly 4 on the top of the push assembly 5 relatively located above, the limit assembly 4 adopts two cross-connected clamps The holding arm 4.2 includes a clamping rod 4.2.1 and a clamping head 4.2.2. When the two clamping rods 4.2.1 rotate around the hinge and move away from each other, the two clamping heads 4.2.2 are in an open state. At this time, the anchor rod 14 can be placed between the two opened clamping heads 4.2.2. When the two clamping rods 4.2.1 rotate around the hinge and move toward each other, the two clamping heads 4.2.2 are in a closed state, thereby clamping the anchor rod 14, thereby achieving the positioning of the anchor rod 14 in the axial direction. Two groups of conical rollers 4.8 are symmetrically and movably arranged on the two clamping heads 4.2.2, with a total of four conical rollers 4.8 , a clamping space for clamping the anchor rod 14 is formed between the four conical rollers 4.8, which can ensure the centering accuracy of the anchor rod 14 while limiting the position of the anchor rod 14. At the same time, when the anchor rod 14 passes through the four conical rollers 4.8 and moves upward, the four conical rollers 4.8 rotate, the clamping force on the anchor rod 14 is reduced, and the friction between the anchor rod 14 and the four conical rollers 4.8 is reduced, so that the anchor rod 14 can continue to move upward. When the anchor rod 14 moves downward, since the rollers are conical rollers 4.8, the four conical rollers 4.8 rotate, and the clamping force of the four conical rollers 4.8 on the anchor rod 14 is increased. The addition makes it impossible for the anchor rod 14 to continue to move downward, thereby realizing the unidirectional positioning of the anchor rod 14, and there is no need to add a limiting structure at the bottom of the anchor rod 14, so that the overall structure of the anchor rod magazine is simple, the layout is compact, the space occupied is small, and the overall size is short, which can be significantly smaller than the length of the anchor rod 14. When matched with the anchor drilling rig body, the docking device can have a larger docking space during the docking process with the anchor rod 14, avoiding the problem of docking failure caused by the long docking stroke due to the long structure size of the anchor rod magazine during the docking process between the docking device and the anchor rod 14, thereby improving the docking success rate of the anchor rod 14.

[0042] Further, see Figure 4As shown, the limit assembly 4 also includes four roller mounting seats 4.6 and four second elastic members 4.7. The four roller mounting seats 4.6 are movably arranged on the chuck 4.2.2 relative to the position of the conical roller 4.8, and the conical roller 4.8 is arranged inside the roller mounting seat 4.6; the second elastic member 4.7 is a torsion spring, one end of which is connected to the roller mounting seat 4.6, and the other end is connected to the chuck 4.2.2. Specifically, the four roller mounting seats 4.6 are sleeved on the chuck 4.2.2 and are arranged corresponding to the positions of the four conical rollers 4.8, that is, the distance between two opposite conical rollers 4.8 is adjusted by the clamping arm 4.2, and the distance between two adjacent conical rollers 4.8 is adjusted by the roller mounting seat 4.6. By arranging the second elastic member 4.7 between each roller mounting seat 4.6 and the chuck 4.2.2, and the second elastic member 4.7 is a torsion spring, the conical roller 4.8 can always be kept in a clamped state under the action of the spring force.

[0043] Further, see Figure 5 As shown, the tapered roller 4.8 has a large end and a small end, and the small end is arranged close to the push assembly 5; the four roller mounting seats 4.6 can all rotate along the extension direction of the frame assembly 3.2, so that the center line formed by the surfaces of the two tapered rollers 4.8 are not parallel to the center line of the tapered roller 4.8. Specifically, the large end of the conical roller 4.8 faces upward and the small end faces downward, and is arranged in the roller mounting seat 4.6, and the roller mounting seat 4.6 can rotate along the extension direction of the frame assembly 3.2. When the anchor rod 14 passes through the four conical rollers 4.8 and moves upward, the four conical rollers 4.8 can rotate upward along the axial direction of the chuck 4.2.2. At this time, the two large ends relative to or adjacent to each other gradually move away from each other, and the clamping force of the four conical rollers 4.8 on the anchor rod 14 is reduced, so that the anchor rod 14 can move upward under less resistance. When the anchor rod 14 passes through the four conical rollers 4.8 and moves downward, the four conical rollers 4.8 can rotate downward along the axial direction of the chuck 4.2.2. At this time, the two large ends relative to or adjacent to each other gradually approach each other, and the clamping force of the four conical rollers 4.8 on the anchor rod 14 is increased until the anchor rod 14 can no longer move downward, so that the limit assembly 4 realizes the self-locking function, thereby realizing the unidirectional limitation of the anchor rod 14.

[0044] Continue to refer to Figure 4As shown, the limit assembly 4 also includes a base plate 4.1, a guide slot 4.4 and two guide links 4.5. The base plate 4.1 is connected to the push assembly 5. The guide slot 4.4 is arranged on the base plate 4.1. One end of the two guide links 4.5 is symmetrically arranged on the two clamping rods 4.2.1, and the other end is connected by a hinge pin. The hinge pin is suitable for sliding along the guide slot 4.4. Specifically, the base plate 4.1 is made of steel plate and is used to connect with the push assembly 5. The guide slot 4.4 is machined and arranged on the base plate 4.1, and is used to limit and guide the hinge pin, thereby achieving limit and guide of the two clamping arms 4.2, ensuring that the limit assembly 4 will not be offset and tilted, ensuring the centering accuracy of the anchor rod 14, so that the anchor rod 14 is maintained as follows. Figure 4 Theoretical position of anchor rods in 4.9.

[0045] Continue to refer to Figure 4 As shown, the limit assembly 4 also includes a first elastic member 4.3, which is connected to two clamping rods 4.2.1. The force of the first elastic member 4.3 can be transmitted to the conical roller 4.8 through the clamping rod 4.2.1 to clamp the anchor rod 14, and the two clamping rods 4.2.1 can return to their initial positions under the action of the first elastic member 4.3. The first elastic member 4.3 is a spring. Of course, the first elastic member 4.3 can also be an elastic member that is elastic and can be restored, such as a spring.

[0046] Reference Figure 1 As shown, the anchor rod bin also includes two displacement sensors 6 and two measuring rods 7. The two displacement sensors 6 are both arranged on the outer wall of the frame assembly 3.2 in the vertical direction and are arranged on the same side of the frame assembly 3.2 close to the push assembly 5. The two measuring rods 7 are respectively arranged on the side of the two push assemblies 5 facing the anchor rod 14, and the two measuring rods 7 are provided with electromagnetic sheets on the side close to the displacement sensor 6; the displacement sensor 6 measures the distance between the measuring rod 7 and the frame assembly 3.2; the thickness of the measuring rod 7 is less than the distance between the push assembly 5 and the anchor rod 14. Specifically, the two measuring rods 7 are respectively arranged on the side of the two pushing components 5 facing the anchor rod 14, and can move together with the pushing components 5. Electromagnetic plates are provided on the side close to the displacement sensor 6, so that the displacement sensor 6 can receive the distance signal between the measuring rod 7 and the frame component 3.2, that is, the stroke size of the pushing component 5, thereby ensuring the synchronous movement of the two pushing components 5 to prevent the anchor rod 14 from being offset or broken. At the same time, the stop position can be set by program to ensure that the anchor rod 14 reaches the working position, thereby ensuring the docking accuracy and centering accuracy of the anchor rod 14.

[0047] Reference Figure 3As shown, the slideway assembly 3.1 is in an "L" shape, with a groove inside, and tracks 3.1.4 are arranged on both sides of the groove parallel to the frame assembly 3.2, and a first swing cylinder ear seat 3.1.2 is arranged on the end of the slideway assembly 3.1 close to the swing assembly. Specifically, the end of the slideway assembly 3.1 is a limit plate 3.1.1 with a tip, and the push assembly 5 clamps the anchor rod 14 and slides along the track 3.1.4 to send the anchor rod 14 to the working position.

[0048] Reference Figure 2 As shown, the swing assembly includes a fixed seat 1 and a swing cylinder 2. The fixed seat 1 includes a back plate 1.1, two side plates 1.2, a second swing cylinder ear seat 1.3 and two limit screws 1.4. The two side plates 1.2 are symmetrically arranged on both sides of the back plate 1.1. The back plate 1.1 is connected to the anchor drilling rig body. The second swing cylinder ear seat 1.3 is arranged on the inner wall of the back plate 1.1. The two limit screws 1.4 are respectively arranged on the inner walls of the two side plates 1.2. One end of the swing cylinder 2 is hingedly connected to the second swing cylinder ear seat 1.3, and the other end is hingedly connected to the first swing cylinder ear seat 3.1.2. The end of the slideway assembly 3.1 close to the fixed seat 1 is suitable for rotating inside the fixed seat 1 until it abuts against the limit screws 1.4. Specifically, the back plate 1.1 is connected to the side of the anchor drilling rig body by bolts, and the distance between the two side plates 1.2 is greater than the height of the slide assembly 3.1, so that the limit plate 3.1.1 can rotate inside the fixed seat 1 under the drive of the swing cylinder 2 until the limit plate 3.1.1 abuts against the limit screw 1.4.

[0049] Reference Figure 6 As shown, the push assembly 5 includes a sliding seat 5.1, a pushing cylinder 5.2 and a plurality of anchor rod mounting ear seats 5.3. The sliding seat 5.1 has two opposite sides provided with sliding grooves suitable for sliding along the track 3.1.4. The plurality of anchor rod mounting ear seats 5.3 are equidistantly arranged on one side of the sliding seat 5.1 close to the anchor rod 14. One end of the pushing cylinder 5.2 is connected to the end of the sliding seat 5.1, and the other end is connected to the inner wall of the slideway assembly 3.1. Specifically, the anchor rod mounting ear seat 5.3 is used to install the anchor rod 14, and in this embodiment, three anchor rod mounting ear seats 5.3 are arranged on the side of the sliding seat 5.1 close to the anchor rod 14, and a push cylinder ear seat 3.1.3 is also arranged inside the slideway assembly 3.1, so that one end of the push cylinder 5.2 is hingedly connected to the push cylinder ear seat 3.1.3, and the other end is connected to the sliding seat 5.1. By opening sliding grooves on both sides of the opposite sides of the sliding seat 5.1, the sliding seat 5.1 can slide along the track 3.1.4 driven by the push cylinder 5.2, thereby driving the anchor rod mounting ear seat 5.3 to move, so that the anchor rods 14 in the anchor rod bin are docked with the docking device in turn.

[0050] A second aspect of this embodiment provides an anchor drilling rig, referring to Figure 7As shown, it includes the anchor barrack described in any one of the above items, and also includes a main frame 8, a switching mechanism 9, a drill box 10, an anchor box 11, a feeding mechanism 12 and a top plate assembly 13;

[0051] The switching mechanism 9 is arranged at the bottom of the main frame 8, and the switching mechanism 9 includes a switching cylinder and a switching guide plate. The switching mechanism 9 is suitable for driving the drill box 10 or the anchor box 11 to switch between the working position and the waiting position; the drill box 10 and the anchor box 11 are both arranged on the switching guide plate, and a drill rod is arranged in the drill box 10, and the anchor box 11 is suitable for connecting with the anchor rod 14; the feeding mechanism 12 is suitable for driving the drill box 10 and the anchor box 11 to move axially along the main frame 8 to realize the feeding of the drill box 10 and the anchor box 11. Specifically, the feeding mechanism 12 includes a feeding cylinder, a feeding chain and a feeding guide plate. The feeding guide plate can slide up and down along the feeding guide column under the action of the feeding cylinder, and the switching guide plate is connected to the feeding guide plate, thereby driving the drill box 10 and the anchor box 11 to feed; the top plate assembly 13 is arranged on the top of the main frame 8, including a supporting top plate, a drill clamping connecting rod and a drill clamping cylinder, which is used to support the coal wall and realize the top connection.

[0052] During the specific work, the drill rod and the anchor rod 14 are installed. The anchor rod 14 is fixed in the anchor rod bin under the action of the limit assembly 4. The switching mechanism 9 switches the drill box 10 to the working position. The hydraulic system supplies hydraulic oil to the drill box 10. The drill box 10 drives the drill rod to rotate. At the same time, the feed mechanism 12 drives the drill box 10 to rise and start drilling in the coal seam roof. After the drilling is completed, the resin anchoring agent is put into the drilled hole. The two swing cylinders 2 of the anchor rod bin with the limit assembly 4 are simultaneously introduced with pressure oil to swing the anchor rod bin to the installation position of the anchor rod 14. At this time, the axis of the first anchor rod 14 in the anchor rod bin is aligned with the axis of the anchor box 11, and the displacement sensor The device 6 outputs a signal to the control system of the anchor drilling rig, and the push assembly 5 stops the first anchor rod 14 at this position; the feeding mechanism 12 slowly drives the anchor box 11 to rise slightly, and the anchor box 11 rotates while rising, so as to achieve the docking of the anchor box 11 and the first anchor rod 14. During the docking process, the anchor box 11 drives the first anchor rod 14 to rotate. When the anchor rod 14 rotates, the conical roller 4.8 rotates freely under the drive of the anchor rod 14, so as to avoid the problems of wear and heat caused by the intense friction between the anchor rod 14 and the U-shaped clamp when the U-shaped clamp is used; the feeding mechanism 12 continues to drive the anchor box 11 to rise at a certain amplitude, and the anchor rod 14 is in the anchor box 1 Under the action of the feed thrust, the conical roller 4.8 in the limit assembly 4 is pushed open, so that the conical roller 4.8 rotates upward along the axis of the clamping arm 4.2. At this time, the clamping force of the conical roller 4.8 on the anchor rod 14 is reduced, and the anchor rod 14 can move upward with less resistance until the top of the anchor rod 14 enters the clamping hole of the clamping mechanism; hydraulic oil is supplied to the swing cylinder 2 to make the anchor rod bin swing back to the waiting state.
