Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering construction machinery, in particular to an anchor rod trolley construction device. BACKGROUND

[0002] Anchor rod support is a crucial reinforcement means in tunnel, slope and foundation pit engineering. In tunnel construction, the worse the surrounding rock condition is, the longer the anchor rod length is required, in order to obtain better reinforcement effect. However, in actual construction, especially in tunnels with small cross section, there is a significant contradiction between the construction length of anchor rod and the operation space of trolley.

[0003] At present, anchor rod installation is generally carried out by anchor rod trolley in tunnel construction. The anchor rod installation mechanism of the anchor rod trolley in the prior art usually adopts a rigid guide beam as a support and guide structure. This design has an inherent defect: in order to ensure that the anchor rod can be pushed to the hole bottom throughout the process, the total length of the guide beam must be significantly greater than the length of the anchor rod being constructed. For example, to install a 4-meter-long anchor rod, the total length of the guide beam may need to be more than 6 meters, of which more than 2 meters of length is wasted invalid space to meet the travel requirements of the anchor rod during pushing. This leads to the fact that in tunnels with limited cross section, either the anchor rod of sufficient length cannot be installed to ensure safety, or a more bulky trolley must be used, which reduces the applicability and flexibility of the equipment, and also increases the manufacturing cost and construction difficulty.

[0004] Therefore, a new anchor rod installation device with compact structure and capable of realizing "short guide beam and long anchor rod" construction is urgently needed to solve the contradiction between the construction length of anchor rod and the construction space in the prior art. SUMMARY

[0005] The purpose of the present application is to provide an anchor rod trolley construction device which significantly shortens the length of the guide beam while ensuring the anchor rod installation function, and solves the installation problem of long anchor rod in a small space.

[0006] The present application is implemented by adopting the following technical scheme: an anchor rod trolley construction device, characterized by a base for being installed on a guide beam and moving along the guide beam; a clamping mechanism installed on the base, the clamping mechanism having an openable and closable clamping part for clamping or releasing an anchor rod; a pushing mechanism installed on the base in front of the clamping mechanism; the pushing mechanism comprising a pushing pipe member capable of pitching and swinging relative to the base and a pushing head provided at the front end of the pushing pipe member; and a connecting rod driving mechanism connected between the base and the pushing pipe member for driving the pushing pipe member and the pushing head thereon to switch between a prone posture for avoiding the anchor rod and a lifted posture for pushing the anchor rod.

[0007] Furthermore, the linkage drive mechanism includes a parallelogram mechanism composed of linkage one and linkage two, one end of linkage one and linkage two is hinged to the push base plate weldment on the base, and the other end is hinged to the push tube.

[0008] Furthermore, the linkage drive mechanism also includes a drive cylinder, one end of which is hinged to a cylinder mounting base fixed on the base, and the other end is hinged to the first linkage. The parallelogram mechanism is driven to move by the extension and retraction of the drive cylinder.

[0009] Furthermore, the clamping mechanism includes a pair of relatively rotatable clamping rods, with the clamping part disposed at the upper end of the pair of clamping rods; and a clamping cylinder for driving the pair of clamping rods to open and close.

[0010] Furthermore, the pair of clamping rods are hinged to the clamping rod weldment fixed on the base by a pin; the clamping cylinder is connected to the lower part of the clamping rod by a pin.

[0011] Furthermore, the device also includes rollers for supporting the anchor bolts, the rollers being positioned in front of the clamping mechanism.

[0012] Furthermore, a wall plate is fixed on the base for fixing hydraulic pipelines.

[0013] The anchor bolt trolley construction device of the present invention has the following advantages: This invention utilizes an innovative parallelogram linkage mechanism to drive the pitching motion of the pushing pipe fitting, combined with the intermittent pushing method of the clamping mechanism, thereby significantly reducing the longitudinal dimension of the entire device. The guide beam length no longer needs to be more than 2 meters longer than the anchor bolt, achieving a near-matching or even shorter length between the guide beam and the anchor bolt, greatly improving the adaptability to construction within narrow tunnel cross-sections.

[0014] The core technology lies in breaking down the long-stroke push into a cyclical process of "clamping-pushing-releasing-retracting," which, combined with the final jacking mechanism, perfectly resolves the contradiction between installing long anchor bolts and limited working space. This allows for the installation of longer anchor bolts on the same machine, enhancing the trolley's performance and application range.

[0015] The entire workflow, including the opening and closing of the clamping mechanism, the pitching of the pushing mechanism, and the forward and backward movement of the entire device, can be programmed and controlled by the hydraulic system. This reduces manual intervention and labor intensity, while ensuring the accuracy and stability of the pushing process, which helps to improve the efficiency and quality of anchor bolt installation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example

[0020] like Figure 1 As shown, this embodiment of the invention provides an anchor bolt trolley construction device, which mainly consists of an installation base plate 1, a wall plate 2, a clamping rod weldment 3, a clamping rod 4, a clamp 5, a clamping cylinder 6, a first pin 7, a second pin 8, a roller 9, a cylinder mounting base 10, a pushing cylinder 11, a third pin 12, a pushing base plate weldment 13, a first connecting rod 14, a second connecting rod 15, a fourth pin 16, a fifth pin 17, an anchor bolt pushing pipe weldment 18, and a pushing head 19.

[0021] The through-wall plate 2, clamping rod weldment 3, hydraulic cylinder mounting base 10, and pushing base plate weldment 13 are all bolted to the mounting base plate 1, forming the basic frame of the device. Two clamping rods 4 are hinged to the clamping rod weldment 3 via pin 7, enabling swinging motion. A clamping hydraulic cylinder 6 is installed at each end of the lower part of the clamping rod 4, connected to the clamping rod 4 via pin 8, and used to drive the opening and closing action of the clamping rod 4. A clamp 5 is bolted to the upper end of the clamping rod 4 for directly clamping the anchor rod. A roller 9 is fixed to the front end of the clamping rod weldment 3 via a mounting plate, serving to support and guide the anchor rod.

[0022] The push base plate weldment 13 and the anchor rod push tube weldment 18 are connected by two connecting rods 14 and 15. Connecting rods 14 and 15 are hinged to the push base plate weldment 13 and the anchor rod push tube weldment 18 by pin 5 17, forming a parallelogram linkage mechanism to ensure motion stability. One end of the push cylinder 11 is hinged to the cylinder mounting base 10 by pin 3 12, and the other end is hinged to connecting rod 14 by pin 4 16. The parallelogram mechanism is driven by the extension and retraction of the push cylinder 11. The push head 19 is installed at the front end of the anchor rod push tube weldment 18 by welding or bolting, and is used to finally push the anchor rod. The entire device is mounted on the guide beam by the mounting base plate 1 and moves back and forth as a whole by an external drive device.

[0023] The working principle of this device is as follows: In its initial state, the device is located at the rear end of the guide beam. When it is necessary to push a long anchor rod, the pushing cylinder 11 is first activated to extend it forward, pushing the connecting rod 14 to rotate around the pin 17, causing the anchor rod pushing tube welded part 18 and the pushing head 19 to swing downward to avoid interference from the anchor rod. At this time, the clamping cylinder 6 is in the contracted state, driving the clamping rod 4 to open outward through the pin 7, so that the clamp 5 is in the open position, making it convenient for manual or mechanical placement and positioning of the anchor rod on the roller 9.

[0024] After the anchor bolt is inserted, the clamping cylinder 6 extends, pushing the clamping rod 4 inward to close, firmly clamping the anchor bolt through the clamp 5. Then, the external drive device propels the entire device forward along the guide beam, and the mounting base plate 1 drives the clamping mechanism to push the anchor bolt forward, gradually inserting it into the anchor bolt hole in the tunnel surrounding rock. After advancing a certain distance, the clamping cylinder 6 retracts again, causing the clamping rod 4 to open, releasing the anchor bolt, and then the entire device retracts to the rear end of the guide beam. This cycle is repeated until the exposed length of the anchor bolt is reduced to a preset range, ensuring that most of the anchor bolt has entered the hole.

[0025] Next, the push cylinder 11 retracts, pulling the connecting rod 14 in the opposite direction, causing the anchor pusher pipe weld 18 and the pusher head 19 to lift upwards. The entire device then moves forward again via the drive mechanism until the tail of the anchor bolt is inserted into the groove of the pusher head 19. The device continues to advance, using the pusher head 19 to finally push the anchor bolt into place, completing the entire installation of the anchor bolt. Finally, the device retracts to the initial position, awaiting the construction of the next anchor bolt.

[0026] Throughout the process, the parallelogram mechanism ensures the smooth movement of the pushing pipe, while the clamping mechanism enables intermittent advancement of the anchor bolt, thus completing the installation of long anchor bolts within the short guide beam space. This compact design effectively resolves the conflict between anchor bolt construction length and working space. The total length of the guide beam can be shortened by more than 2 meters compared to traditional devices; for example, when installing a 4-meter anchor bolt, the guide beam only needs to be about 4 meters, significantly improving space utilization. Simultaneously, the device achieves automated operation through hydraulic drive, improving the efficiency and accuracy of anchor bolt installation, reducing manual intervention, and lowering construction costs. Furthermore, the supporting role of roller 9 prevents anchor bolt bending, and the final pushing of the pusher head 19 ensures accurate anchor bolt placement, resulting in high overall reliability and suitability for narrow working conditions such as tunnels and slopes.

[0027] The above embodiments describe the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
