Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction, and specifically to an anchor rod library and an operating arm of an anchor rod trolley with the anchor rod library. Background Art

[0002] An anchor rod trolley is an integrated movable vehicle equipment for drilling and grouting support of anchor rods. Most of the existing anchor rod trolleys are equipped with an anchor rod library for storing and transporting drill rods or anchor rods, which is used to convey drill rods or anchor rods to a drilling assembly or a grouting assembly, replacing the traditional manual operation of replacing rods, improving the safety and operation efficiency during tunnel operations. Most of the anchor rod libraries configured on anchor rod trolleys are in the form of a rotating disk, around which multiple rods are fixed, and the corresponding rod is rotated to the working position by rotation. However, the rotation angle of the existing rotating disk type anchor rod library is not accurate enough or there is no linkage with the corresponding rod feeding assembly. Once there is a misoperation, it is easy to damage the equipment or components and affect the operation efficiency. Summary of the Invention

[0063] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0064] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0066] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0067] like Figure 1 As shown, the present application provides an anchor rod warehouse 1 for storing and transporting anchor rods, and the anchor rod warehouse 1 is matched and installed on the operating arm of the anchor rod trolley, and the operating arm also includes at least a grouting assembly 3 and a propulsion beam 2. Among them, the propulsion beam 2 extends along a first direction, and its front end is used to abut against the rock wall and is relatively fixed; the grouting assembly 3 is slidably installed on the propulsion beam 2 and can slide along the first direction; the anchor rod warehouse 1 is fixedly installed on one side of the propulsion beam 2, and can transport the anchor rod 4 to the front of the grouting assembly 3, and the grouting assembly 3 is then docked and installed with the anchor rod 4, and the anchor rod 4 is sent into the hole of the rock wall, and then the grouting operation is performed, which saves the operation of manually replacing the anchor rod 4 and improves the operation efficiency.

[0068] See also Figures 1 to 3 , Figures 22 to 25 The anchor bar library 1 includes a support bar 11, a turntable 12, a driving device for driving the turntable 12 to rotate, and a rod delivery assembly 13. The support bar 11 is a straight bar, extending along a first direction, and fixedly mounted on one side of the propulsion beam 2.

[0069] The turntable 12 is annular and can rotate around an axis parallel to the first direction. When working normally, it is used to store various rods, such as drill rods, etc. In this embodiment, the rod is an anchor rod 4. The detailed storage structure is that multiple anchor rods 4 are embedded on the outer peripheral side of the turntable 12. There are several turntables 12 and they are inserted into the support rods 11 at intervals, which provide good support and fixation for the longer anchor rods 4 to prevent the anchor rods 4 from bending and deforming due to gravity.

[0070] The rod delivery assembly 13 is arranged on the support rod 11, and includes a push block 134 located on the inner side of the anchor rod for pushing it out of the turntable 12 and delivering it to a set position. When the push block 134 is reset, the drive device drives the turntable 12 to rotate so that the next anchor rod 4 is in place.

[0071] The driving device is used to drive the turntable 12 to rotate, and rotate the anchor rod 4 to the position corresponding to the rod feeding assembly 13. Specifically, the driving device can be a stepping motor cooperating with a turbine and worm structure to drive the turntable 12 to rotate a certain angle, and the return control of the rod feeding assembly 13 can be interlocked through some electrical components. This improves the accuracy of the rotation angle of the turntable 12, realizes the linkage between the turntable 12 and the rod feeding assembly 13, improves the automation level, and avoids accidents such as the rod feeding assembly 13 failing to clamp the anchor rod 4 or hitting the anchor rod 4 and causing it to fall off.

[0072] In one embodiment, the driving device can also include a Geneva drive assembly 14, which includes a Geneva sprocket 141 and a Geneva wheel 142. An internal gear ring meshing with the Geneva wheel 142 is provided on the inner circumference of the turntable 12. The specific transmission process is as follows: when the Geneva sprocket 141 rotates one week, the Geneva wheel 142 rotates a certain angle, such as 90°, and then the rotation angle of the turntable 12 is controlled according to the tooth number ratio between the Geneva wheel 142 and the turntable 12. In a preferred embodiment, as Figure 26 shown, a plurality of Geneva wheels 142 are fixedly connected by a transmission rod 152 to achieve synchronous rotation between several turntables 12. The rotation of the Geneva sprocket 141 can be driven by a motor or linked by other mechanical mechanisms.

[0073] The anchor rod library 1 of the present application is provided with a Geneva drive assembly 14 to accurately index the rotation angle of the turntable 12. Compared with the traditional motor-controlled turntable rotation structure, the gear meshing is combined with the Geneva drive structure, making the single rotation angle accuracy higher. And the corresponding angle control can be achieved by changing the number of slots of the Geneva wheel 142, which is convenient and reliable. Relying on the accurate indexing characteristics of the Geneva drive assembly 14, the consistency of the rotation angle of the turntable 12 each time is ensured. Similarly, the anchor rod 4 can be rotated into place at the position required by the rod feeding assembly 13, and accidents such as the anchor rod 4 being pushed off or the rod feeding assembly 13 failing to pick up the anchor rod 4 are not likely to occur, and the overall operation is more stable.

[0074] In one embodiment, a plurality of positioning seats 112 that cooperate with the rotation of the turntable 12 are spaced on the support rod 11. Specifically, the turntable 12 is sleeved on the outer circumference of the positioning seat 112, and the Geneva drive assembly 14 is fixedly installed on the positioning seat 112. The positioning seat 112 can be eccentric or concentric with the support rod 11. In a preferred embodiment, it is eccentrically arranged. This structure can leave a space between the support rod 11 and the anchor rod 4 for installing the rod feeding assembly 13 and the Geneva drive assembly 14 or other driving devices, saving space.

[0075] Please refer to again Figures 22 to 25, in one embodiment, a ratchet wheel 143 synchronously rotating with the Geneva drive wheel 141 is installed on the positioning seat 112. The ratchet wheel 143 has a rotating shaft 145 rotatably fitted with the positioning seat 112. The rotating shaft 145 is relatively fixed to the Geneva drive wheel 141, and a driving wheel 146 is sleeved on the rotating shaft 145. A reset member 147 (such as a torsion spring) is provided between the driving wheel 146 and the rotating shaft 145, and the driving wheel 146 is linked with the rod feeding assembly 13 through a wire 148; a pawl 144 meshing with the ratchet wheel 143 is provided on the driving wheel 146 to drive the ratchet wheel 143 to rotate only in one direction.

[0076] The linkage mode between the driving wheel 146 and the rod feeding assembly is as follows: an annular groove 149 for the wire 148 to surround and be fixed is formed on the outer periphery of the driving wheel 146. The wire 148 can pull and drive the driving wheel 146 to rotate, or the driving wheel 146 rotates and resets by relying on the reset member 147 to promote the reset of the wire 148. The specific working process is as follows:

[0077] When the rod feeding assembly 13 is about to complete the return, it causes the wire 148 to move in one direction, drives the driving wheel 146 to rotate in one direction, and the pawl 144 on the driving wheel 146 abuts against the ratchet wheel 143 to rotate in the same direction, then drives the Geneva drive wheel 141 to rotate through the rotating shaft 145 and finally drives the turntable 12 to rotate; after the above operations are completed, the reset member 147 is relied on to cause the driving wheel 146 to rotate and reset in the opposite direction relative to the rotating shaft 145 and pull the wire 148 to reset. During this period, both the ratchet wheel 143 and the rotating shaft 145 are fixed, and the cooperation between the pawl 144 and the ratchet wheel 145 can limit the reverse rotation of the Geneva drive wheel 141 to avoid the reverse rotation of the turntable 12 and cause accidents.

[0078] In one embodiment, a pin shaft 150 is fixedly installed through the positioning seat 112 on the side close to the Geneva transmission assembly 14. A double-hook spring 151 for driving the Geneva drive wheel 141 to reset is fixedly installed between the pin shaft 150 and the Geneva drive wheel 141 to assist the Geneva transmission assembly 14 to quickly reset.

[0079] In one embodiment, the ratchet wheel 143 and the Geneva drive wheel 141 are coaxially arranged and are arranged on both sides of the positioning seat 112, maximizing the use of the installation space of the positioning seat 112, reducing the size of the positioning seat 112 in the radial direction, and finally reducing the radial size of the anchor rod library 1, with a compact structure.

[0080] Such as Figures 18 to 21As shown, in one embodiment, a plurality of notches 121 for accommodating the anchor rod 4 and a locking mechanism for preventing the anchor rod 4 from detaching from the notch 121 are provided on the outer peripheral side of the turntable 12. The locking mechanism includes a locking member 122 rotatably mounted on the support rod 11 and an elastic member 123 acting on the locking member 122. The locking member 122 has a clamping arm 1221 that cooperates with one side of the notch 121 to clamp the anchor rod 4 and a braking arm 1222 that abuts against the support rod 11 to prevent the locking member 122 from rotating. Among them, please refer specifically to Figure 19 , the clamping arm 1221 has a locked state that restricts the anchor rod 4 from coming out by relying on the elastic member 123 to extend into the notch 121, and an unlocked state that drives the locking member 122 to withdraw from the notch 121 after the push block 134 pushes the anchor rod 4, while compressing the elastic member 123. This locking device effectively restricts the anchor rod 4 from detaching except on the movement trajectory of the push block 134, avoiding the anchor rod 4 from falling off during the operation of the operating arm.

[0081] Please refer to again Figures 19 to 21 , in one embodiment, the positioning seat 112 has a circumferential surface that cooperates with the turntable 12, and an avoidance groove 1121 for avoiding the braking arm 1222 is provided at a position corresponding to one of the notches 121 on the circumferential surface. The avoidance groove 1121 is used to leave an activity gap for the braking arm 1222, facilitating the unlocking operation of the cooperation between the locking member 122 and the push block 134; and the outer peripheral surfaces of the braking arm 1222 and the positioning seat 112 always abut against each other except at the avoidance groove 1121, prompting the locking member 122 to always be in the locked state, avoiding falling off due to operation vibration or gravity, and further improving the working stability of the device.

[0082] In one embodiment, the rod feeding assembly 13 includes a push block 134 located inside the anchor rod for pushing it away from the turntable 12 and a lifting frame for driving the push block 134. The push block 134 has magnetism, and restricts the anchor rod 4 by magnetic attraction after the anchor rod 4 detaches from the turntable 12; the lifting frame includes a first swing rod 131 and a second swing rod 132 with one end hinged to the support rod 11 and the other end hinged to the push block 134, and a driving rod 133 with one end hinged to the first swing rod 131 and the other end slidably cooperating with the support rod 11. The push block 134 can move radially away from or close to the support rod 11 and has a working state and a waiting state. Specifically:

[0083] Please refer to with emphasis Figure 7 , Figures 9 to 11 , in the working state, the push block 134 moves in a direction away from the support rod 11 and forms a movement trajectory. The plane swept by this movement trajectory coincides with the anchor rod 4 and the final installation position of the anchor rod 4. During the movement, pick up and fix an anchor rod 4 on the turntable 12, continue to move, remove the anchor rod 4 and the turntable 12 until reaching the limit position of the rod feeding assembly 13, and this limit position is the final installation position, facilitating subsequent docking and installation.

[0084] In the waiting state, the push block 134 is close to the support rod 11 and is between the anchor rod 4 and the support rod 11. The push block 134 switches between the working state and the waiting state. After the anchor rod 4 is docked and installed, when the push block 134 moves from the working state to the waiting state and is between the anchor rod 4 and the support rod 11, the turntable 12 rotates to rotate the new anchor rod 4 to the plane corresponding to the working state, so that the push block 134 can pick up and fix the anchor rod 4.

[0085] The first swing rod 131, the second swing rod 132, the push block 134 and the support rod 11 form a four-bar linkage. When the push block 134 moves from the waiting state to the working state, the driving rod 133 causes the driving rod 133 to slide along the support rod 11 through the driving device set on the anchor rod library 1, so that the first swing rod 131 rotates and drives the push block 134 away from the support rod 11 through the four-bar linkage. During the whole movement process, the push block 134 always remains parallel to the anchor rod 4. After the anchor rod 4 is docked and installed, the driving rod 133 slides in the opposite direction, causing the rod delivery assembly 13 to change from the working state to the waiting state. Since the first swing rod 131 and the second swing rod 132 are both fixed at one end, the movement process of the anchor rod 4 is to push obliquely to the front end, so that the anchor rod library 1 can be set as close to the rear end as possible relative to the propulsion beam 2. Compared with the existing anchor rod library, more space is reserved at the front end to avoid collision with the rock wall during operation.

[0086] The magnetic attraction method allows a certain gap error when picking up the anchor rod 4, which is convenient for production and assembly. It also eliminates the opening and closing action of the traditional claw structure, and the structure is simple. The specific structure is as follows:

[0087] See also Figure 17 Embodiment 1: The push block 134 includes two clamping plates 1342 hinged to the first swing rod 131 and the second swing rod 132 and a magnetic core block 1343 located between the two clamping plates 1342. The upper surface of the core block 1343 is always parallel to the axial direction of the anchor rod 4. Since the anchor rod 4 is cylindrical, the contact is line contact at this time. No matter whether the anchor rod 4 is fixedly picked up or detached, compared with the traditional clamping structure, there is no other action, the structure is simple, and the stability is high.

[0088] See also Figures 12 to 16 , Embodiment 2: The push block 134 includes two clamping plates 1342 hinged to the first swing rod 131 and the second swing rod 132 and a magnetic core block 1343 located between the two clamping plates 1342. One end of the core block 1343 is hinged to the second swing rod 132 and the other end is separated from the first swing rod 131. A lever 1344 for moving the core block 1343 to separate it from the anchor rod 4 is provided at the hinge between the two clamping plates and the first swing rod 131. The core block 1343 has:

[0089] In the attracted state, the core block 1343 is kept parallel to the axis direction of the anchor rod 4. Since the anchor rod 4 is cylindrical, it is a line contact at this time;

[0090] In the separated state, the core block 1343 is rotated by the lever 1344, forming a certain angle with the axial direction of the anchor bolt 4, and the contact is a point contact when they touch.

[0091] Only after the anchor bolt 4 is pushed and butt-jointed and installed, the core block 1343 relies on the rotating part of the lever 1344 to disengage from the anchor bolt 4 and is in the separated state, weakening the magnetic attraction force with the anchor bolt 4, making it more convenient to disengage, and not generating a strong acting force on the anchor bolt 4 at the moment when the push block 134 disengages, thus preventing the anchor bolt 4 from bending. In other states, the core block 1343 resets and is in the attracted state, always attracting and fixing the anchor bolt 4. In this embodiment, the detailed structure is as follows: The core block 1343 has a notch 1345 at the second swing rod 132. A nut 1346 that always extends into the notch 1345 is threadedly connected to the lever 1344. A traction wire 1347 is also fixedly connected to the lever 1344. The traction wire 1347 bypasses above the lever 1344 and is arranged through the second swing rod 132, and the lever 1344 is pulled and rotated by a driving element (such as a cylinder or an oil cylinder) provided on the anchor bolt library 1; A torsion spring (not shown in the figure) for returning to the attracted state is provided at the first swing rod 131 of the core block 1343.

[0092] The specific working principle is as follows: The core block 1343 is always in the attracted state by relying on the torsion spring. When the anchor bolt 4 is butt-jointed and installed in place, the traction wire 1347 drives the lever 1344 to rotate under the drive of the driving element, and the nut 1346 abuts against the inner wall of the notch 1345, pulling it to rotate and be in the separated state.

[0093] Please refer specifically to Figure 15 and Figure 17 On the basis of Embodiment 1 and Embodiment 2, two clamping plates 1342 form a groove 1348 for accommodating the anchor bolt 4. A magnetic steel 1349 with magnetic suction force is fixedly installed on the surface of the core block 1343. The groove 1348 covers a part of the outer circumference of the anchor bolt 4, making the fixation of the anchor bolt 4 and the push block 134 more firm. In a preferred solution, the lower clamping plate 1342 extends perpendicular to the core block 1343, causing the groove 1348 to be in an "L" shape, facilitating magnetic attraction and fixation when approaching the anchor bolt 4, and providing a part of the supporting force to offset gravity. A magnetic steel 1349 is fixedly installed on the extended part of the clamping plate 1342, so that 1 / 4 of the outer circular surface of the anchor bolt 4 receives a relatively large magnetic suction force, further improving the connection stability. Among them, the magnetic steel 1349 is fixed on the clamping plate 1342 and the core block 1343 through fasteners, which is convenient for replacement and maintenance.

[0094] In one embodiment, a slider 111 driven by an oil cylinder 113 to move in a first direction is provided on the support rod 11. The slider 111 is hinged to the driving rod 133. One end of the cable 148 is connected to the slider 111. Wherein, the slider 111 slides on the support rod 11 in the first direction, so that the driving rod 133 changes its motion. In a preferred embodiment, the support rod 11 is a hollow rod member, the slider 111 is slidably installed inside the support rod 11, and correspondingly, the oil cylinder 113 can also be installed inside the support rod 11, reducing the volume of the bolt magazine 1, and the support rod 11 can be used as a sliding guide for the slider 111. The cable 148 can be connected to the slider 111 by bypassing a fixing pin (not shown in the figure) provided on the support rod 11. When the rod feeding assembly 13 returns to its original position, the slider 111 moves and pulls the cable 148 to finally drive the turntable 12 to rotate, so that the next bolt 4 is in place.

[0095] Please refer to again Figure 2 and Figure 5 , in one embodiment, there are at least two sets of rod feeding assemblies 13. The adjacent sliders 111 are connected by a connecting rod 114, so that multiple sets of rod feeding assemblies 13 can move synchronously; two sets of rod feeding assemblies 13 provide better support and fixation for the bolt 4, avoiding the bolt 4 from slipping during transportation or bending under gravity and being unable to be accurately docked and installed.

[0096] In the bolt magazine of the present application, the rod feeding assembly is arranged between the storage rack and the support rod. Compared with the traditional gripper device arranged outside the bolt magazine, the installation distance from the propulsion beam is shortened, the influence brought by vibration is reduced, and the working stability of the operating arm is improved. Moreover, the movement trajectory of the rod feeding assembly is a plane, and this plane coincides with the bolt and the final installation position of the bolt, making the rod feeding more accurate. And the rod feeding assembly is a multi-link mechanism, and the rods are interconnected with each other. Only one driving device is required to realize the rod feeding operation. Compared with the traditional multi-dimensional gripper mechanism, the structure is simpler and the stability is higher. And a fixed seat with magnetism is set to attract and pick up the bolt, replacing the existing gripper structure, eliminating the opening and closing actions, and the connection and fixation method is simple and reliable, improving the operation stability.

[0097] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not conflict, it should be considered as the scope recorded in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the various embodiments involved at the same time.

[0098] The above embodiments only represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several variations and improvements can still be made, and these all fall within the protection scope of the present application.
