[0014] In one possible implementation, a limiting assembly is also included, the limiting assembly comprising a limiting seat and a limiting plate, one of the limiting seat and the limiting plate being connected to the bottom end of the fork carriage, and the other of the limiting seat and the limiting plate being connected to the guide frame, the limiting seat and the limiting plate being bolted together.

[0034] As shown in the background art, in related technologies, the grouting machine lifting mechanism generally includes a drive component, a guide component, and a fork carriage. The guide component is slidably connected to the fork carriage that carries the grouting machine. The guide component extends in the vertical direction, and the drive component transmits force to the fork carriage through the guide component, thereby driving the fork carriage to move up and down in the vertical direction to transport the grouting machine.

[0035] However, the drive components or guide components occupy vertical space, increasing the size of the anchor bolt trolley and affecting its effectiveness in confined spaces such as tunnels.

[0036] To address the aforementioned technical problems, this application provides a grouting machine lifting mechanism for an anchor bolt trolley and the anchor bolt trolley itself. The grouting machine lifting mechanism includes a support assembly and a drive structure. The support assembly includes a support frame, a guide frame, and a fork carriage. The guide frame is connected to one end of the support frame, and the fork carriage is slidably connected to the guide frame. The support frame is located on one side of the fork carriage's lifting direction. The drive structure is mounted on the support frame and is used to drive the fork carriage to move up and down along the extension direction of the guide frame. The anchor bolt trolley includes a frame assembly, grouting equipment, and the aforementioned grouting machine lifting mechanism. The grouting machine lifting mechanism is connected to the frame assembly, and the grouting equipment is mounted on the fork carriage of the grouting machine lifting mechanism. This avoids the drive structure occupying vertical space, reducing the volume of the anchor bolt trolley and increasing its usability.

[0037] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0038] Reference Figures 1 to 4 As shown, in a first aspect, embodiments of this application provide a grouting machine lifting mechanism for an anchor bolt trolley, comprising:

[0039] The support assembly 100 includes a support frame 110, a guide frame 120, and a fork carriage 130. The guide frame 120 is connected to one end of the support frame 110, and the fork carriage 130 is slidably connected to the guide frame 120. The support frame 110 is located on one side of the lifting direction of the fork carriage 130.

[0040] The drive structure 200 is mounted on the support frame 110 and is used to drive the fork carriage 130 to move up and down along the extension direction of the guide frame 120.

[0041] Understandably, referring to Figures 1 to 4 As shown, the fork carriage 130 generally includes a base plate 131 and a vertical frame 132 connected to the base plate 131. The base plate 131 is used to support the grouting equipment (described below), and the vertical frame 132 is slidably connected to the guide frame 120 so that the fork carriage 130 supporting the grouting equipment can be raised and lowered vertically, facilitating the adjustment of the grouting equipment's position by the operator. A drive structure 200 can be connected to the fork carriage 130 to drive the fork carriage 130 to move up and down along the extension direction of the guide frame 120. Furthermore, as... Figure 1 As shown, the drive structure 200 can be mounted on the support frame 110, which is located on one side of the lifting direction of the fork carriage 130. That is, the drive structure 200 is located on one side of the lifting direction of the fork carriage 130, preventing the drive structure 200 from occupying the vertical lifting space.

[0042] Specifically, the grouting machine lifting mechanism connects both the support frame 110 and the fork carriage 130 to the guide frame 120 extending vertically. The support frame 110 is positioned on one side of the lifting direction of the fork carriage 130, and the drive structure 200 is mounted on the support frame 110, meaning the drive structure 200 is also located on one side of the lifting direction of the fork carriage 130. The drive structure 200 drives the fork carriage 130 to move vertically, avoiding the drive structure 200 occupying vertical space, reducing the volume of the anchor trolley, and increasing the usable range of the anchor trolley.

[0043] In one possible implementation, combining Figure 1 , Figure 3 and Figure 4 As shown, the guide frame 120 extends vertically, the support frame 110 is vertically connected to one side of the guide frame 120, and the fork carriage 130 is slidably connected to the other side of the guide frame 120.

[0044] Specifically, in combination Figure 1 , Figure 3 and Figure 4As shown, the support frame 110 and the fork carriage 130 are located on opposite sides of the guide frame 120, that is, the support frame 110 and the fork carriage 130 are in the same horizontal direction, and the drive structure 200 is set on the support frame 110, that is, the drive structure 200 is set in the horizontal direction to prevent it from occupying vertical space, thereby avoiding an increase in the overall size of the anchor bolt trolley. When the tunnel is a relatively narrow space, this setting makes it easier for the anchor bolt trolley to enter for work, greatly increasing the usable range of the anchor bolt trolley.

[0045] In one possible implementation, combining Figure 2 and Figure 3 As shown, the drive structure 200 includes a drive component 210 and a transmission assembly 220 connected to the drive component 210. The transmission assembly 220 includes a fixed plate 221, a first pulley 222, a support 223, a second pulley 224, and a wire rope 225. The fixed plate 221 and the support 223 are both fixedly connected to the support frame 110. The first pulley 222 and the second pulley 224 are spaced apart in the horizontal direction. The first pulley 222 is fixedly connected to the support frame 110 through the support 223. The wire rope 225 is sleeved on the outside of the first pulley 222 and the second pulley 224. One end of the wire rope 225 is connected to the fixed plate 221, and the other end of the wire rope 225 is connected to the fork carriage 130.

[0046] Specifically, in combination Figures 1 to 3 As shown, support 223 is mounted on support frame 110. First pulley 222 is pinned to support 223. Second pulley 224 is spaced apart from first pulley 222 in the horizontal direction. Output end of drive member 210 is connected to second pulley 224. Wire rope 225 is wound around first pulley 222 and second pulley 224. One end passes through fixed plate 221 and is fixed with a nut to fix it to fixed plate 221. The other end extends vertically and is connected to fork carriage 130. Output end of drive member 210 can extend and retract in the horizontal direction, which can push second pulley 224 to move in the horizontal direction, thereby driving wire rope 225 to move, and thus lifting fork carriage 130.

[0047] Furthermore, refer to Figure 1 and Figure 3 As shown, at least two first pulleys 222 and at least two second pulleys 224 are provided. Adjacent first pulleys 222 and adjacent second pulleys 224 are arranged in parallel and spaced apart, and are connected to each other by a connecting shaft 226. The output end of the drive unit 210 is connected to the connecting shaft 226 between the two second pulleys 224.

[0048] Specifically, in combination Figure 1 and Figure 3As shown, at least two first pulleys 222 can be provided. Two adjacent first pulleys 222 are arranged in parallel and spaced apart, and two adjacent first pulleys 222 are connected by a connecting shaft 226, which passes through the support 223. Similarly, at least two second pulleys 224 are also provided. The second pulleys 224 and the first pulleys 222 are on the same horizontal line so that the wire rope 225 can be completely wound around the second pulleys 224 and the first pulleys 222. Adjacent second pulleys 224 are also connected by a connecting shaft 226. The output end of the drive unit 210 is connected to the connecting shaft 226 to drive the second pulleys 224 to move in the horizontal direction.

[0049] And, as Figure 2 As shown, the wire rope 225 is connected to the fork carriage 130 through at least one connecting component 300. The connecting component 300 includes a lug 310, a lug plate 320, and a connector. The lug 310 is connected to the end of the wire rope 225, the lug plate 320 is installed on the top of the fork carriage 130, and the lug 310 and the lug plate 320 are connected through the connector.

[0050] Understandably, the end of the wire rope 225 connected to the fork carriage 130 is provided with a lug 310, and a pair of lug plates 320 are provided at opposite positions on the fork carriage 130. The lug 310 is inserted between the pair of lug plates 320, and a connector passes through the lug 310 and the lug plates 320, thus fixing the wire rope 225 to the fork carriage 130. The lug 310, lug plates 320, and connector ensure the stability of the fork carriage 130 and prevent it from falling.

[0051] In one possible implementation, the drive component 210 is a telescopic cylinder, which is used to drive the second pulley 224 to reciprocate in the horizontal direction.

[0052] Specifically, the drive unit 210 can be a telescopic cylinder. When working, the output end of the drive unit 210 is in the horizontal direction and is transmitted to the fork carriage 130 through the wire rope 225, thereby driving the fork carriage 130 to move vertically along the guide frame 120.

[0053] In one possible implementation, combining Figure 3 and Figure 4 As shown, it also includes a sliding assembly 400, which includes a fixing member 410 and an inner roller 420. The fixing member 410 is connected to the fork carriage 130, and the inner roller 420 is connected to the side of the fixing member 410 facing the guide frame 120. The inner side of the guide frame 120 facing the fixing member 410 has a groove 121 extending in the vertical direction, and the inner roller 420 is slidably connected in the groove 121.

[0054] Specifically, in combination Figure 3 and Figure 4 As shown, in order to guide the movement of the guide frame 120 and the fork carriage 130, a slide groove 121 can be opened on the opposite inner side of the guide frame 120. The slide groove 121 extends in the vertical direction, and the fork carriage 130 is raised along the slide groove 121.

[0055] At the same time, such as Figure 4 As shown, in order to ensure smooth movement of the fork carriage 130 during lifting, a fixing member 410 can be provided on the upright frame 132. The fixing member 410 is provided with an inner roller 420. The inner rollers 420 are spaced apart in the vertical direction and roll in the slide groove 121, replacing sliding friction with rolling friction, which effectively improves the smoothness of movement of the fork carriage 130.

[0056] Furthermore, refer to Figure 3 and Figure 4 As shown, the sliding assembly 400 also includes an outer roller 430, which is connected to the fork carriage 130. The outer roller 430 is parallel to the inner roller 420, and the outer roller 430 is disposed on the outer side of the guide frame 120 away from the slide groove 121. The rolling surface of the outer roller 430 is in sliding contact with the outer side of the guide frame 120.

[0057] Specifically, such as Figure 3 and Figure 4 As shown, multiple outer rollers 430 can also be provided on the fixing member 410. The outer rollers 430 are also spaced apart in the vertical direction and are parallel to the inner rollers 420. The rolling surface of the outer rollers 430 slides in contact with the outer side of the guide frame 120 away from the slide groove 121.

[0058] It is understandable that when the fork carriage 130 carries a heavy load, the fork carriage 130 will wobble during the lifting process along the slide 121. In order to avoid relative wobbling between the fork carriage 130 and the guide frame 120, the outer roller 430 can be set to limit the guide frame 120 and enhance the stability of the fork carriage 130 during the lifting process.

[0059] In one possible implementation, such as Figure 3 and Figure 4 As shown, it also includes a limiting assembly 500, which includes a limiting seat 510 and a limiting plate 520. One of the limiting seat 510 and the limiting plate 520 is connected to the bottom end of the fork carriage 130, and the other of the limiting seat 510 and the limiting plate 520 is connected to the guide frame 120. The limiting seat 510 and the limiting plate 520 are bolted together.

[0060] Specifically, refer to Figure 3 and Figure 4As shown, after the fork carriage 130 is raised to the designated position, the height of the fork carriage 130 needs to be fixed. Therefore, a limiting seat 510 and a limiting plate 520 can be set on the upright 132 and the guide frame 120 respectively. The position where the limiting seat 510 and the limiting plate 520 overlap is the position where the fork carriage 130 needs to be raised to a fixed height. At this time, the limiting seat 510 and the limiting plate 520 can be connected by bolts to fix the fork carriage 130.

[0061] There are no specific restrictions on whether the fork carriage 130 is equipped with a limit seat 510 or a limit plate 520, as long as it can fix the fork carriage 130 and the guide frame 120.

[0062] Secondly, this application also provides an anchor bolt trolley, including a frame assembly, grouting equipment and the grouting machine lifting mechanism of the anchor bolt trolley, wherein the grouting machine lifting mechanism is connected to the frame assembly and the grouting equipment is installed on the fork carriage 130 of the grouting machine lifting mechanism.

[0063] Specifically, the anchor bolt trolley may include a frame assembly, which may include a cab and a control device that controls the cab to lift and tilt back. One end of the frame assembly may be connected to the working arm, the propulsion component, and drilling mechanisms such as rock drills, while the other end of the frame assembly may be connected to grouting equipment.

[0064] The system utilizes a control device to raise, lower, and tilt the cab, improving the driver's field of vision, enabling precise operation, and ultimately enhancing construction quality. During operation, the propulsion unit drives the rock drill to the designated drilling position, drills anchor bolt holes, and uses grouting equipment to inject mortar into the anchor bolt holes through grouting pipes. During vehicle movement, the grouting equipment is mounted on the forklift 130 of the grouting machine's lifting mechanism. The drive structure 200 and guide frame 120 of the grouting machine's lifting mechanism work together to raise the grouting equipment, preventing contact and collision with ground obstacles. Furthermore, when it is necessary to add grout to the equipment, the drive structure 200 and guide frame 120 work together to lower the grouting equipment to the ground, facilitating the addition of grout by construction personnel.

[0065] Finally, it should be noted that other embodiments of this application will readily conceive of by those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and alterations may be made without departing from its scope. The scope of this application is limited only by the appended claims.
