Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction, and specifically to an anchor rod library for automatically feeding rods 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 anchor rod grouting support. 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 operation.

[0003] For example, the Chinese patent document with the publication number CN 209308720 U discloses a rod changing device for an anchor rod machine, including a propulsion beam and a hydraulic rock drill. One side of the propulsion beam is provided with an anchor rod bin for storing drill rods or anchor rods, and a sliding guide rail is arranged on the propulsion beam in the front-back direction; the rock drill is slidably connected to the sliding guide rail; a rod loading device is arranged on the propulsion beam, and a rod grasping device is arranged on the anchor rod bin. The rod loading device transfers the drill rod or anchor rod in the anchor rod bin to the front end of the rock drill, and the rod grasping device grabs the drill rod on the caliper device through a gripper; the anchor rod bin includes a protective cover, a motor, a front rod storage disc and a rear rod storage disc. A central shaft is connected between the front rod storage disc and the rear rod storage disc. Grooves for accommodating drill rods or anchor rods are arranged on the circumferences of the front rod storage disc and the rear rod storage disc, and the motor drives the front rod storage disc and the rear rod storage disc to swing. This rod changing device enables the anchor rod machine to switch between anchor rod and rock drilling operations, realizing the multi-functionality of the anchor rod trolley. Among them, the rod grasping device is fixedly installed on the side of the propulsion beam, between the propulsion beam and the anchor rod bin. When conveying rods, the conveyance of the rods is achieved through multi-axis motion changes and the opening and closing of the gripper, achieving the purpose of automatic rod conveyance, improving the operation efficiency and production safety compared with the traditional manual method. However, since the rod grasping device occupies a certain volume, it extends the installation distance between the anchor rod bin and the propulsion beam, resulting in the amplification of vibration during operation and affecting the working stability of the anchor rod bin.

[0004] Moreover, the rod grasping device has at least two-dimensional changes. For example, the opening and closing at the gripper, and the rotation of the swing arm relative to the base. Multiple dimensions require different driving mechanisms (cylinders or motors) to be configured, increasing the weight of the whole machine. And as long as the accuracy of one dimension is insufficient, it will cause the inability to grasp the rod or the rod to be not installed in place, and the equipment stability is poor.

[0005] Similarly, the Chinese patent document with publication number CN 207863988 U discloses an anchor drilling rig operation system, in which the fixed part is also a gripper structure, and the gripper structure is generally equipped with a corresponding cylinder or motor to realize opening and closing. If it is set nearby, the volume is too large, and the opening and closing of the gripper itself also occupies part of the volume; if it is remotely controlled by pipelines or wires (wires), a large space needs to be reserved for the pipelines or wires for arrangement. Dust or other particles are easily generated during tunnel construction, which can easily cause the gripper to get stuck or other failures. Once the gripper fails, during the transportation process, the rods cannot be installed correctly or the rods are pushed out of the anchor warehouse, which seriously affects the operation efficiency.

[0055] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0056] 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 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.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used 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.

[0058] In this application, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity or order of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0059] As Figure 1 shown, this application provides an anchor rod storage 1 for storing and transporting anchor rods. The anchor rod storage 1 is installed on the operating arm of an anchor rod trolley, and the operating arm further includes at least a grouting assembly 3 and a propulsion beam 2. Among them, the propulsion beam 2 extends in 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 storage 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. The grouting assembly 3 is docked and installed with the anchor rod 4, and the anchor rod 4 is sent into the hole in the rock wall, and then grouting operation is carried out, eliminating manual replacement of the anchor rod 4 and improving the operation efficiency.

[0060] Please refer to Figures 1 to 11 , the anchor rod storage 1 includes a support rod 11, a turntable 12 and a rod feeding assembly 13. Among them, the support rod 11 is a straight rod member, extends in the first direction, and is fixedly installed on one side of the propulsion beam 2.

[0061] The turntable 12 is annular and there are several of them, and they are sleeved on the support rod 11 at intervals. The turntable 12 can rotate along an axis parallel to the first direction, and it is used to store various rod members, such as drill rods, etc. These rod members are all made of cast iron or other magnetic materials. In this embodiment, the rod member is the anchor rod 4. The detailed storage structure is that multiple anchor rods 4 are clamped on the outer peripheral side of the turntable 12. A locking device for preventing the anchor rod 4 from detaching is provided on the outer peripheral side of the turntable 12, and multiple turntables 12 are cooperated to stably fix the longer anchor rod 4.

[0062] The rod feeding assembly 13 is movably installed on the support rod 11. The rod feeding assembly 13 can be a multi-link mechanism or a scissor mechanism. It includes a magnetic push block 134. The push block 134 is located inside the anchor rod 4 and can move radially away from or close to the support rod 11 and has a working state and a waiting state. Specifically:

[0063] Please refer to with emphasis Figure 7 and Figures 9 to 11 . In the working state, the pushing block 134 moves 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, an anchor rod 4 on the turntable 12 is picked up and fixed by magnetic attraction. Continuing to move, the anchor rod 4 is pushed away from the turntable 12 until it reaches the limit position of the rod feeding assembly 13, and this limit position is the final installation position, which is convenient for subsequent docking and installation.

[0064] . In the waiting state, the pushing block 134 is close to the support rod 11 and is between the anchor rod 4 and the support rod 11. The pushing block 134 switches between the working state and the waiting state. Among them, after the anchor rod 4 is docked and installed, when the pushing 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, which is convenient for the pushing block 134 to suck and fix when pushing.

[0065] The movement trajectory of the pushing block 134 of the rod feeding assembly 13 in the anchor rod library of this application is a plane, and this plane coincides with the axis of the anchor rod 4 and the final installation position. The entire movement and change process is on this plane, with changes in a single dimension. And there is a limit position in the movement process of the rod feeding assembly 13, and this limit position is the final installation position of the anchor rod 4. Compared with the traditional gripper structure perpendicular to the anchor rod 4, the accuracy is higher, the dimensional change is less, and the working stability is higher. And because the movement trajectory is in the same plane as the anchor rod 4, and the anchor rod 4 is fixed by magnetic attraction, the existing gripper opening and closing structure and the operation of adjusting the relative position between the gripper and the anchor rod are omitted, avoiding the anchor rod falling off or not being installed in place due to gripper failure, and further improving the working stability.

[0066] . And when the rod feeding assembly 13 in the anchor rod library is in the waiting state, it is between the anchor rod 4 and the support rod 11. Compared with the structure of the existing rod gripping device arranged outside the anchor rod library, the installation distance from the propulsion beam is shortened, the force arm is shortened, and under the same vibration, the force is smaller, improving the connection stability between the anchor rod library and the propulsion beam, and reducing the volume of the operating arm.

[0067] Please refer to Figures 4 to 8, in one embodiment, the rod feeding assembly 13 includes a lifting frame for driving the pushing block 134. The lifting frame includes a first swing rod 131 and a second swing rod 132, one end of which is hinged to the support rod 11 and the other end is hinged to the pushing block 134, and a driving rod 133, one end of which is hinged to the first swing rod 131 and the other end is slidably engaged with the support rod 11. The first swing rod 131, the second swing rod 132, the pushing block 134 and the support rod 11 form a four-bar linkage mechanism. When the pushing block 134 moves from the waiting state to the working state, the driving rod 133 is urged by a driving device provided on the bolt magazine 1 to slide along the support rod 11, causing the first swing rod 131 to rotate, and driving the pushing block 134 away from the support rod 11 through the four-bar linkage mechanism. During the entire movement process, the pushing block 134 always remains parallel to the bolt 4. After the bolt 4 is butt-mounted, the driving rod 133 slides in the reverse direction, causing the rod feeding assembly 13 to change from the working state to the waiting state. Since one end of both the first swing rod 131 and the second swing rod 132 is fixed, the movement process of the bolt 4 is to push obliquely forward, so that the bolt magazine 1 can be arranged as close to the rear end of the propulsion beam 2 as possible. Compared with the existing bolt magazine, more space is left at the front end, avoiding collision with the rock wall during operation.

[0068] In one embodiment, a slider 111 driven by an oil cylinder 113 is provided on the support rod 11, and the slider 111 is hinged to the driving rod 133. Wherein, the slider 111 slides along the first direction on the support rod 11, causing the driving rod 133 to move and change. In a preferred embodiment, the support rod 11 is a hollow rod, the slider 111 is slidably installed inside the support rod 11, and the corresponding 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.

[0069] Please refer to again Figure 2 and Figure 5 , in one embodiment, there are at least two sets of rod feeding assemblies 13, and 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 or bending under gravity during transportation and being unable to be accurately butt-mounted.

[0070] The pushing block 134 has magnetism, and its specific structure is as follows:

[0071] Please refer to Figure 17 , Embodiment 1: The pushing 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 bolt 4. Since the bolt 4 is cylindrical, the contact is a line contact at this time. Whether it is fixed to pick up or detach from the bolt 4, compared with the traditional clamping structure, there is no other action, the structure is simple, and the stability is high.

[0072] 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:

[0073] 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;

[0074] In the separated state, the core block 1343 is rotated by the lever 1344, and forms a certain angle with the axial direction of the anchor rod 4, and the contact is point contact.

[0075] Only after the anchor rod 4 is pushed and docked, the core block 1343 is partially separated from the anchor rod 4 and is in a separated state by the rotation of the lever 1344, which weakens the magnetic attraction of the anchor rod 4 and makes it easier to separate. The core block 1343 will not exert a strong force on the anchor rod 4 to bend it at the moment when the push block 134 is separated. In other states, the core block 1343 is reset and in an attracted state, and can be attracted and fixed to the anchor rod 4 at any time. In this embodiment, the detailed structure is as follows: a notch 1345 is provided on the core block 1343 at the second rocker arm 132, a nut 1346 is threadedly connected to the lever 1344 and always extends into the notch 1345, a pull wire 1347 is also fixedly connected to the lever 1344, the pull wire 1347 passes over the top of the lever 1344 and is arranged in the second rocker arm 132, and pulls and rotates the lever 1344 by means of a driving element (such as a cylinder or an oil cylinder) provided on the anchor rod depot 1; a torsion spring (not shown) for returning the core block 1343 to the attracted state is provided at the first rocker arm 131.

[0076] The specific working principle is: the core block 1343 is always in the attracted state by the torsion spring. When the anchor rod 4 is docked and installed in place, the pull 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, causing it to rotate and be in a separated state.

[0077] Please refer to Figure 15 and Figure 17, on the basis of the first and second embodiments, two clamping plates 1342 form a groove 1348 for accommodating the anchor rod 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 rod 4, making the fixation of the anchor rod 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 rod 4, and providing a part of the supporting force to offset gravity. The extended part of the clamping plate 1342 is fixedly installed with a magnetic steel 1349, so that a 1 / 4 outer circular surface of the anchor rod 4 is subjected to a 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.

[0078] As Figures 18 to 21 shown, in one of the embodiments, a plurality of notches 121 for accommodating the anchor rod 4 and a locking mechanism for preventing the anchor rod 4 from disengaging from the notch 121 are provided on the outer peripheral side of the turntable 12. The locking mechanism includes a locking member 122 rotatably installed 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 locking state that restricts the anchor rod 4 from disengaging by relying on the elastic member 123 to extend into the notch 121, and a release 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 disengaging except on the movement track of the push block 134, avoiding the anchor rod 4 from falling off during the operation of the operating arm.

[0079] Please refer to again Figures 19 to 21 , in one of the embodiments, the support rod 11 has a circumferential surface that cooperates with the turntable 12. A relief groove 1121 for accommodating the braking arm 1222 is provided at the position corresponding to one of the notches 121 on the circumferential surface. The relief groove 1121 is used to leave an activity gap for the braking arm 1222, facilitating the locking member 122 to cooperate with the push block 134 to complete the unlocking operation; and the braking arm 1222 and the outer circumferential surface of the support rod 11 always abut except at the relief groove 1121, causing 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.

[0080] In one of the embodiments, the support rod 11 is eccentrically arranged relative to the turntable 12. A positioning seat 112 that rotates in cooperation with the turntable 12 is provided on the support rod 11, leaving an installation space for the rod feeding assembly 13, and the mechanism or assembly for driving the turntable to rotate can be installed on the positioning seat 112, making the structure of the anchor rod library 1 more compact.

[0081] In the bolt storage of the present application, the rod feeding assembly is arranged between the turntable and the support rod. Compared with the traditional rod grasping device arranged outside the bolt storage, the installation distance from the propulsion beam is shortened, the influence caused 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, which 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, with the rods being interconnected. Only one driving device is required to achieve the rod feeding operation. Compared with the traditional multi-dimensional gripper mechanism, the structure is simpler and the stability is higher. In addition, a pusher block 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 fixing method is simple and reliable, improving the operation stability.

[0082] 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 there is no contradiction in the combination of these technical features, 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 respective embodiments involved at the same time.

[0083] The above embodiments only represent several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
