[0003] In order to improve work efficiency, the existing working arm with only grouting components installed will install an anchor rod warehouse for storing and transporting anchor rods on one side of the propulsion beam. The hydraulic and pneumatic pipelines and power supply pipelines connected to the grouting components on the working arm are coiled and fixed through the coils set on the other side or the rear end, which increases the overall space and is not conducive to tunnel operations.

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art 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.

[0063] 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.

[0064] See also Figure 1 , Figure 2 , Figure 8 and Fig. 9 The present application provides an operating arm of an anchor trolley, including a propulsion beam 1, a first slide plate 21, a grouting assembly 3 and a drag chain 33.

[0065] The propulsion beam 1 is a straight section profile, and its own length direction is the first direction. The propulsion beam 1 extends along the first direction and has a front end and a rear end. The front end is against the rock wall to achieve relative fixation between the operating arm and the rock wall, which is convenient for the equipment installed thereon to operate, such as the grouting operation of the grouting component 3.

[0066] The first slide plate 21 is plate-shaped and is slidably mounted on the propulsion beam 1 and can slide back and forth along a first direction. Generally, a sliding rail and a slideway are provided between the two.

[0067] The grouting assembly 3 is fixedly mounted on the first slide plate 21. The grouting assembly 3 includes a grouting pipe 31 having an inlet end and an outlet end, and a second hose 34 connected to the grouting assembly 3. The grouting pipe 31 is used for grouting into the anchor bolt installation hole. It can be away from or close to the propulsion beam 1. The outlet end is used to dock the installation anchor bolt 7 and transport it into the corresponding anchor bolt installation hole, or directly dock the anchor bolt installation hole for grouting without installing the anchor bolt 7. The second hose 34 is a plurality of pipeline groups for transporting hydraulic oil, compressed air and slurry, as well as power supply, wherein the pipeline for transporting slurry is docked to the inlet end of the grouting pipe 31, and the remaining pipelines are docked to other components on the grouting assembly 3.

[0068] The drag chain 33 is composed of a plurality of unit links to form a long strip, and the whole is laid flat on the side of the propulsion beam 1 by magnetic attraction along the first direction. At the same time, the moving path of the grouting assembly 3 should be avoided. The interior of the drag chain 33 is hollow, and is used to pass the second rubber hose 34. The drag chain 33 has a fixed end fixedly installed near the front end of the propulsion beam 1, and a movable end that bends and moves with the reciprocating sliding of the grouting assembly 3 by relying on the second rubber hose 34. Specifically, the grouting assembly 3 slides forward, and the movable end bends forward and forms a U-shape with the fixed end. The grouting assembly 3 slides back to its original position, and the movable end is quickly attracted to the propulsion beam 1 by magnetism. The drag chain 33 is a steel drag chain, and the corresponding part of the propulsion beam 1 that is attracted by the drag chain 33 is magnetic.

[0069] The drag chain 33 in this embodiment is in the shape of a long strip, and its length is from the front end of the propulsion beam 1 to the rear end, which is roughly the same as the sliding stroke of the grouting assembly 3, and is arranged parallel to the moving path of the grouting assembly 3, so that when the grouting assembly 3 moves forward, compared with the traditional coiled telescopic structure, the force pulling the grouting assembly 3 is reduced or eliminated, and the problem of the winder being stuck and unable to grout will not occur. When the grouting assembly 3 returns to its original position, the drag chain 33 returns to its original position quickly by magnetic attraction, which eliminates the problem of the second hose 34 returning to its original position and slacking compared with the traditional structure, thereby improving the grouting operation efficiency of the grouting assembly 3.

[0070] like Figure 3 As shown, in one embodiment, the operating arm includes an anchor rod warehouse 8 for storing and delivering anchor rods 7 to the grouting pipe 31, which is fixedly installed on one side of the propulsion beam 1 along the first direction, and the drag chain 33 is arranged between the propulsion beam 1 and the anchor rod warehouse 8. The width of the propulsion beam 1 is reduced, making the structure more compact. Specifically, as Figure 8 and Fig. 9 As shown, the push beam 1 is fixedly installed with a magnetic crosspiece 35 on the side wall of the anchor bar 8 in a vertical first direction. The crosspiece 35 extends vertically in the first direction toward one end of the anchor bar 8, so that the drag chain 33 is partially located below the grouting assembly 3. In another embodiment, as shown in FIG. Fig.10 and Fig.11 As shown, the crosspiece 35 is perpendicular to the first direction, and the drag chain 33 is located below the grouting assembly 3 as a whole. The crosspieces 35 of the above two embodiments are used to attract and support the drag chain 33. Preferably, there are multiple crosspieces 35, which are arranged at intervals along the first direction. Compared with the whole piece attracting the drag chain 33, multiple pieces are arranged to reduce the weight of the equipment, and reduce the force required to overcome the magnetic attraction force to bend the drag chain 33 when the grouting assembly 3 moves forward, thereby improving the working efficiency.

[0071] like Figure 4 to Figure 7 As shown, in one embodiment, the operating arm includes a first slide plate 21 slidably mounted on the propulsion beam 1, a drilling assembly 22 slidably mounted on the first slide plate 21 and working alternately with the grouting assembly 3, a hose reel 24 slidably mounted on the propulsion beam 1 and capable of reciprocating along the first direction with the drilling assembly 22 and having a sliding speed half that of the drilling assembly 22, and a first rubber hose 25 having one end connected to the drilling assembly 22 and the other end fixed to the propulsion beam 1, bypassing the hose reel 24 in the middle, and maintaining a tensioned state when the drilling assembly 22 and the hose reel 24 slide along the first direction. The grouting assembly 3 is mounted on the first slide plate 21.

[0072] In one embodiment, the operating arm includes a second slide plate 27, a hose reel 24 and a first rubber hose 25, wherein the second slide plate 27 is slidably mounted on the propulsion beam 1 and can slide along the first direction with the first slide plate 21, and the sliding speed of the second slide plate 27 is half of that of the first slide plate 21; the hose reel 24 is mounted on the second slide plate 27 and has multiple grooves for convenient winding of the first rubber hose 25; the first rubber hose 25 is a pipeline for conveying hydraulic oil or compressed air and power to the hose reel 24, one end of which is connected to the drilling assembly 22, and the other end is fixed on the propulsion beam 1, bypassing the hose reel 24 in the middle, and maintaining a tensioned state when the drilling assembly 22 and the hose reel 24 slide along the first direction. The first rubber hose 25 and the hose reel 24 slide synchronously with the drilling assembly 22 in a similar manner to a movable pulley, and compared with the traditional structure, the length of the first rubber hose 25 is half of the propulsion beam 1 and can always maintain a tensioned state, avoiding loosening and failure when the drilling assembly 22 returns to its original position, and reducing the weight of the operating arm. The grouting assembly 3 and the drilling assembly 22 are separately provided with independent hose moving systems, so that the two can work alternately without interfering with each other. In a preferred embodiment, the fixed end of the first hose 25 and the propulsion beam 1 is arranged on the side of the propulsion beam 1 opposite to the drag chain 33, and the two hose moving systems do not interfere with each other, which is convenient for operation and maintenance.

[0073] like Figure 6 to Figure 18 As shown, in one embodiment, the propulsion beam 1 is provided with a first chain 11 driving the drilling assembly 22 to slide along the first direction and a second chain 14 extending along the first direction, and a follower gear 15 is provided in the gap between the first chain 11 and the second chain 14 to move synchronously with the hose reel 24; at the starting position of the drilling assembly 22, the follower gear 15 only keeps meshing with the first chain 11, and at the starting stage of the drilling assembly 22 sliding along the first direction, the hose reel 24 is driven by the drilling assembly 22 through the first rubber hose 25, so that the follower gear 15 is meshed with the second chain 14. The rear end and the front end of the propulsion beam 1 are respectively provided with a driving gear 12 and a driven sprocket 13, which are tensionally meshed and connected with the first chain 11 to make it present a closed waist shape, and the driving gear 12 is connected to a motor 29 driving it to rotate, and the second chain 14 is a straight chain, which is fixedly connected to the inside of the propulsion beam 1 and is located below the first chain 11. The specific working principle is as follows:

[0074] When the motor 29 is running, the first chain 11 moves driven by the driving gear 12, causing the follower gear 15 to rotate. Since the follower gear 15 is also engaged with the second chain 14, it moves forward or backward relative to the second chain 14, and at the same time, drives the hose reel 24 fixed to the follower gear 15 to slide together.

[0075] like Fig.12 , Fig.13 ,as well as Figure 19 to Figure 21As shown, in one embodiment, the hose reel 24 is slidably mounted on the second slide plate 27, and can slide back and forth along the second direction along with the drilling assembly 22, so as to cause the first hose 25 to move sideways along with the drilling assembly 22, thereby avoiding damage caused by the sideways movement of the drilling assembly 22. Specifically, Figure 12 to Figure 16 As shown, in one embodiment, the first slide plate 21 and the second slide plate 27 are respectively provided with a first mounting seat 2121 and a second mounting seat 2711 that can slide back and forth in the second direction, the drilling assembly 22 and the hose reel 24 are respectively fixed on the first mounting seat 2121 and the second mounting seat 2711, the tail of the first mounting seat 2711 is provided with a coupling member 2122 extending toward the second mounting seat 2711, and the second mounting seat 2711 is provided with a coupling groove 2712 that cooperates with the coupling member 2122. The first mounting seat 2121 and the first slide plate 21 are driven by the oil cylinder to slide in the second direction, and a slide rail and a slide seat are provided between the two mounting seats and the corresponding slide plates to realize sliding in the second direction. When the drilling assembly 22 is in the first working position, the coupling member 2122 and the coupling groove 2712 are coupled to each other, so that the two mounting seats move sideways synchronously. When the drilling assembly 22 moves forward while drilling, the coupling member 2122 and the coupling groove 2712 are separated, and the hose reel 24 moves forward at half the speed of the drilling assembly 22, always keeping the first hose 25 in a tensioned state. The coupling member 2122 is generally a columnar fixing block, which is welded or bolted to the first mounting seat 2121.

[0076] like Figure 10 to Figure 13 As shown, in one embodiment, the grouting assembly 3 includes a lifting frame 32 for moving the grouting pipe 31 so that it can be switched between a second working position and a second standby position; the lifting frame 32 includes a first support rod 321 and a second support rod 322 hinged to the front portion 211 of the first slide plate 21, and the grouting pipe 31 is also hinged to the first support rod 321 and the second support rod 322. The front portion 211 of the first slide plate 21, the first support rod 321, the second support rod 322 and the grouting pipe 31 constitute a foldable four-bar linkage.

[0077] In the second working position, the drilling assembly 22 slides to the first standby position, and the grouting pipe 31 moves close to the propulsion beam 1 until its axis is aligned with the anchor rod installation hole. The grouting pipe 31 can be connected to the anchor rod 7 for grouting, or it can be directly slid to align with the anchor rod installation hole for grouting;

[0078] In the second standby position, the grouting pipe 31 moves away from the propulsion beam 1 until a space is left for the drilling assembly 22 to complete the drilling operation when the drilling assembly 22 is in the first working position.

[0079] Combined with the position change of the drilling assembly 22, the specific operation process is as follows: the drilling assembly 22 is in the first working position. When the operating arm is relatively fixed against the rock wall, the drilling assembly 22 slides forward along the first direction to perform the drilling operation. After the drilling operation is completed, the drilling assembly 22 slides back along the first direction to the rear end of the propulsion beam 1, and at the same time, an anchor rod installation hole is formed on the rock wall. Subsequently, the drilling assembly 22 slides to the first standby position along the second direction, and the grouting pipe 31 of the grouting assembly 3 moves to the second working position, docks with the anchor rod 7, slides forward along the first direction, and delivers the anchor rod 7 into the anchor rod installation hole, and then delivers the slurry. After the grouting operation is completed, the grouting assembly 3 retreats to the original position along the first direction, moves the grouting pipe 31 to the second standby position, and the drilling assembly 22 slides to the first working position. The operating arm moves to the next rock wall for a new round of operations.

[0080] In the first working position, compared with the traditional structure in which the grouting assembly 3 is arranged in parallel and is outside the propulsion beam 1, the grouting assembly 3 and the drilling assembly 22 in the operating arm of the present application are both on the propulsion beam 1, reducing the shaking effect of the grouting assembly 3 itself and the grouting assembly 3 on the operating arm in the case of high-frequency drilling, thereby improving product stability. In the second working position, compared with the traditional structure in which the drilling assembly 22 is entirely outside the propulsion beam 1, only part of the drilling assembly 22 is outside the propulsion beam 1, reducing the load force on the rear end of the propulsion beam 1 and extending the service life of the propulsion beam 1.

[0081] The front part 211 is provided with a driving device 323 (such as an oil cylinder or a gas cylinder) pivotally connected to one of the support rods. The driving device 323 drives the support rod and relies on a four-bar linkage to complete the folding / unfolding operation. The four-bar linkage is to lower the grouting pipe 31 to approach the propulsion beam 1 when folding, and to lift the grouting pipe 31 away from the propulsion beam 1 when unfolding. The plane where the movement path of the grouting pipe 31 is located is always the same plane as the vertical plane of the propulsion beam 1 along the first direction. Compared with the mechanism in which the traditional grouting assembly 3 and the drilling assembly 22 are arranged in parallel and slidably switched, the drilling assembly 22 will appear to be located outside the propulsion beam 1. In this embodiment, the drilling assembly 22 only needs to slide along the second direction to leave space for the grouting pipe 31 to work, so that the sliding stroke along the second direction is reduced, the center of gravity offset of the operating arm due to the movement of the drilling assembly 22 is reduced, and the coaxial accuracy of the anchor rod 7 or the grouting pipe 31 and the anchor rod mounting hole is improved, which is convenient for the subsequent delivery of the anchor rod 7 or direct grouting operation. Among them, the preferred solution is that when the lifting frame 32 moves the grouting pipe 31, the first support rod 321 and the second support rod 322 rotate in the same direction, and always keep the grouting pipe 31 extending along the first direction. The four-bar linkage is a parallelogram structure, so that the grouting pipe 31 is always kept horizontal with the propulsion beam 1, so that when the grouting pipe 31 descends to the second working position toward the front end of the propulsion beam 1, it avoids interference with the drilling assembly 22 at the rear end, and remains coaxial with the anchor rod installation hole, so as to facilitate the horizontal installation of the anchor rod 7.

[0082] like Figure 6 to Figure 13As shown, in one embodiment, the first slide plate 21 is divided into a front portion 211 and a rear portion 212 along a first direction, and the front portion 211 and the rear portion 212 have a combined state that can slide synchronously and a separated state that can slide individually; a part of the first chain 11 is fixedly connected to the front portion 211 to drive the front portion 211 to slide along the first direction; the drilling assembly 22 is slidably installed on the rear portion 212 of the first slide plate 21, and the front and rear portions of the first slide plate 21 are in a combined state when the drilling assembly 22 is in the first working position; the grouting assembly 3 is installed on the front portion 211 of the first slide plate 21, and the front portion 211 and the rear portion 212 of the first slide plate 21 are in a separated state when the grouting pipe 31 is in the second working position. The bottom of the front part 211 is provided with a clamping block 26 fixedly connected by bolts. The clamping block 26 is clamped and fixed on the first chain 11 to realize the fixed connection between the front part 211 and the first chain 11. The mutual connection / separation structure between the front part 211 and the rear part 212 is a connection rod 231 provided on one of them, and a connection hole 232 provided on the other to cooperate with the connection rod 231. When the drilling assembly 22 is in the first working position, the connection rod 231 is inserted into the connection hole 232, and the first chain 11 moves, and the two slide synchronously. Since the anchor rod 7 is not installed in the grouting assembly 3 at this time, it can slide synchronously with the drilling assembly 22. When the drilling assembly 22 is in the first standby position, the connection rod 231 is disengaged from the connection hole 232, and the two are separated. The first chain 11 moves, and only the grouting assembly 3 slides forward alone for grouting operation, so as to prevent the drilling assembly 22 with the drill rod 6 inserted and fixed from sliding forward and hitting the rock wall.

[0083] In one embodiment, the follower gear 15 is always meshed with the first chain 11, and is disengaged from the second chain 14 before the drilling assembly 22 works. At the initial stage of the drilling assembly 22 sliding along the first direction, the drilling assembly 22 slides forward and pulls the first hose 25, and the hose reel 24 is driven to slide forward a short distance through the first hose 25, and the follower gear 15 moves a certain distance accordingly, and then meshes with the second chain 14, and then moves forward at half the speed of the drilling assembly 22. Compared with the traditional structure in which the follower gear 15 is always meshed with the second chain 14, it can be achieved that the grouting assembly 3 keeps idling during the grouting operation.

[0084] The operating arm of the rock drilling trolley of the present application is parallel to the second hose for the grouting assembly. The moving path of the grouting assembly is set on the propulsion beam and is movably installed by magnetic attraction. Compared with the traditional winding telescopic structure of the winding device, it reduces the reaction force acting on the grouting assembly when the grouting assembly moves forward, eliminates the problem of loose pipeline when the grouting assembly returns, ensures stable operation of the equipment, and improves the efficiency of grouting operation. In addition, the first hose moving system of the drilling assembly is set correspondingly to realize the integration of drilling and grouting of the operating arm. The two independent hose moving systems do not interfere with each other, further improving the operation efficiency.
