Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a multi-functional trolley working device that integrates drilling, injection and anchoring on high slopes at multiple workstations. Background Technology

[0002] In the mechanized construction of anchor bolt support for high slopes, integrated drilling, grouting, and anchoring trolleys are widely used because they can integrate multiple processes such as drilling, grouting, and anchoring. However, existing working devices of this type still have some shortcomings: Firstly, during the anchoring operation, especially when pushing long anchor rods, the anchor rod itself has limited rigidity. If only the front gripper and the rear tightening device are used for two-point support, the middle section of the anchor rod is prone to bending and deformation, which can cause it to get stuck when entering the borehole, i.e., the "stuck rod" problem, affecting construction efficiency and success rate.

[0003] Secondly, for continuous operation, the working device is usually equipped with a bolt magazine that stores multiple bolts. For easy bolt retrieval, the bolt magazine is typically located on one side of the working device. This asymmetrical layout causes the center of gravity of the entire working device to shift, generating a large eccentric load moment, which affects the stability of the equipment during operation, especially on rugged slopes where the stability problem is more pronounced.

[0004] Furthermore, the working device of the integrated drilling, injection, and anchoring trolley is usually installed at the end of the trolley boom, which is at a high position. Its structure is complex and has many functional components. When a malfunction occurs or regular maintenance is required, it is difficult for maintenance personnel to access it, which brings great difficulties to the maintenance and troubleshooting of the equipment.

[0005] Therefore, there is an urgent need for an integrated drilling, injection, and anchoring working device that can effectively solve the problems of anchor rod insertion, improve equipment eccentricity, and facilitate high-altitude maintenance. Summary of the Invention

[0006] The technical problem to be solved by this invention is that there is an urgent need in the market for an integrated drilling, injection, and anchoring working device that can effectively solve the problem of anchor rod insertion, improve equipment off-center load, and facilitate high-altitude maintenance.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a multi-functional trolley working device integrating drilling, grouting and anchoring of high slopes, including a grouting device, a rock drilling device, an anchor bolt device, an anchor bolt magazine, a work position switching device, an elevation seat and a support base; The pitch seat is connected to the support base via an amplitude adjustment device; The grouting device, rock drilling device, and anchor bolt device are all installed on the support base; The work position switching device is installed on the support base and is used to drive the rock drilling device, anchor bolt device and grouting device to move to a preset work position. An anchor bolt storage unit is installed on the first side of the support base for storing multiple anchor bolts; The anchor bolt device includes a push beam, a main tray and a secondary tray slidably mounted on the push beam, a tightening device mounted on the main tray, and a clamping device mounted on the secondary tray; the clamping device is used to clamp the bolt body during the bolt pushing process.

[0008] It also includes a maintenance platform, which is installed on the second side of the support base opposite to the anchor bolt library.

[0009] The maintenance platform includes a main platform frame, an adjustable ladder and support brackets located inside the main platform frame, and a sliding door located on its outer side.

[0010] The anchor bolt device also includes an outer grouting pipe, an inner grouting pipe slidably disposed within the outer grouting pipe, a locking device disposed on the main tray, and a gripper disposed at the front end of the propulsion beam; one end of the inner grouting pipe is provided with a locking socket, and the locking device is detachably connected to the locking socket to drive the inner grouting pipe to extend for grouting operations; the tightening device is used to grip and tighten the anchor bolt, and the gripper is used to assist in gripping and supporting the front end of the anchor bolt.

[0011] The rock drilling device includes a propulsion beam, a rock drilling tray and an intermediate tray slidably mounted on the propulsion beam, a rock drill mounted on the rock drilling tray, an intermediate drill bit holder mounted on the intermediate tray, and a front drill bit holder located at the front end of the propulsion beam.

[0012] The anchor bolt magazine includes a rotating shaft, a power source for driving the rotating shaft, and multiple anchor bolt discs coaxially mounted on the rotating shaft, each anchor bolt disc having a workstation for storing anchor bolts.

[0013] It also includes a top-mounted device, which is installed at the front end of the support base and is used to press against the slope working surface during operation.

[0014] The support base includes a main support and brackets a, b, and c, which are spaced apart along the front-back direction and connected to the main support. The rock drilling device and the anchor bolt device can be switched and installed on the left or right mounting positions of brackets a, b, or c, respectively.

[0015] The amplitude adjustment device is a hydraulic cylinder or an electric push rod, used to adjust the pitch angle of the support base relative to the pitch seat.

[0016] The platform's main frame has a bottom mounting frame at its bottom, and the support bracket is welded and fixed to the side wall of the bottom mounting frame. The bottom mounting frame has a built-in adjustable guide rail installed inside, and the platform's main frame is movably mounted inside the built-in adjustable guide rail via a self-stabilizing control base at the bottom. The adjustable ladder is controlled by an electrically controlled adjustment rod linked to the self-stabilizing control base.

[0017] The beneficial effects of this invention are: (1) By setting a clamping device in the middle of the anchor bolt device, the present invention forms a three-point support at the front, middle and rear when pushing the long anchor bolt, which greatly enhances the overall rigidity of the anchor bolt during the pushing process, effectively prevents the phenomenon of the anchor bolt getting stuck due to the bending of the anchor bolt, and improves the success rate and efficiency of the anchoring operation. (2) By setting up a maintenance platform on the side opposite to the anchor bolt magazine on the support base, the platform's own weight is cleverly used to balance the off-center load generated by the anchor bolt magazine, making the center of gravity of the entire working device closer to the center and significantly improving the stability during operation. At the same time, the platform provides operators with a safe and convenient high-altitude working surface, greatly facilitating the daily maintenance and troubleshooting of the working device; (3) The present invention integrates the three major functional modules of rock drilling, grouting and anchoring into a compact working device through the work station switching device, realizing the integrated continuous operation of the whole process, with a high degree of automation, and is particularly suitable for high slope anchor support construction scenarios with limited space and complex environment; (4) By setting a bottom mounting frame at the bottom of the platform main frame and setting a built-in adjustable guide rail in the bottom mounting frame, the self-stabilizing control base at the bottom of the platform main frame is movably installed on the built-in adjustable guide rail. This not only adjusts the horizontal position of the entire platform main frame, but also automatically flips and adjusts according to the angle of the equipment to keep the equipment horizontal. At the same time, the adjustable ladder can be controlled by the electric control adjustment rod to achieve linkage with the self-stabilizing control base, thus making it easier for the operator to have a larger operating range and the operation safety and stability are also better.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figures 1 to 8 As shown in the figure, the multi-functional trolley working device for drilling, grouting and anchoring of high slopes provided in this embodiment of the invention is mainly composed of a support base 7, an elevation seat 6, a rock drilling device 2, an anchor bolt device 3, a grouting device 1, a work position switching device 5, an anchor bolt magazine 4, a maintenance platform 8, a top-mounted device 9, an amplitude adjustment device 10 and a compensation device 11.

[0031] The support base 7 serves as the mounting foundation for the entire working device. For example... Figure 3 As shown, it mainly includes a main support 72 and brackets a71, b73, and c75 connected together along the front-to-back direction via the main support 72 and connecting cylinder 74. Each bracket has two mounting positions, left and right, for mounting the rock drilling device 2 or the anchor bolt device 3. The pitch seat 6 is used to connect with the trolley boom. It is hinged to the support base 7 via an amplitude adjustment device 10, such as a hydraulic cylinder. The pitch angle of the support base 7 relative to the slope can be adjusted by the extension and retraction of the cylinder, so that the working device can adapt to working surfaces with different slopes.

[0032] Rock drilling device 2 is used for drilling operations. For example... Figure 5 As shown, it includes a propulsion beam 27, a rock drill tray 22 that can slide along the propulsion beam 27 under the drive of the propulsion device 23, and an intermediate tray 24. The rock drill 21 is mounted on the rock drill tray 22, and the drill rod 26 is mounted on the output end of the rock drill 21. The intermediate support 25 is mounted on the intermediate tray 24, and the front support 28 is mounted on the front end of the propulsion beam 27, together providing guidance and support for the drill rod 26.

[0033] Anchor bolt device 3 integrates grouting and anchor insertion functions. For example... Figure 4 As shown, its core components include a propulsion beam 313, a main tray 36 driven by a telescopic device 38 and a secondary tray 310 that can slide along the propulsion beam 313. A locking device 34 and a tightening device 35 are installed on the main tray 36. A clamping device 39 is installed on the secondary tray 310. The grouting outer pipe 33 is fixed to one side of the propulsion beam 313 by a bracket 311, and has a slidable grouting inner pipe 31 inside. The tail end of the grouting inner pipe 31 has a locking socket 32. A gripper 312 is installed at the front end of the propulsion beam 313.

[0034] Near the front end gripper 312 of the propulsion beam 313, install a small industrial camera or laser scanner.

[0035] When retrieving the anchor bolt from the bolt magazine 4, the vision system can accurately identify the thread at the end of the anchor bolt and the position of the magazine, guiding the tightening device 35 and the gripper 312 to achieve high-precision automatic alignment and gripping, avoiding bumps and misalignment caused by human operation errors or accumulated mechanical errors. Before inserting the bolt, the grouted borehole can be scanned again for final position fine-tuning to ensure perfect alignment between the anchor bolt and the borehole.

[0036] Anchor bolt storage 4 is used to store spare anchor bolts. For example... Figure 6 As shown, it includes a rotating shaft 43 supported by a rear support 41 and a front support 49. A rod magazine power source 42, such as a swing cylinder, drives the rotating shaft 43 to rotate. Multiple anchor plates 44 are coaxially fixed on the rotating shaft 43, and multiple anchor rods 45 can be circumferentially placed on each anchor plate 44. A support shaft 46 is connected to the rotating shaft 43 via a connecting seat 48, and has multiple brackets 47 for auxiliary support of the anchor rods.

[0037] The maintenance platform 8 is installed on the right side of the support base 7, opposite the anchor bolt magazine 4 on the left. For example... Figure 7 and Figure 8 As shown, it includes a platform main frame 84, an internal adjustable ladder 81 and an external sliding door 83, forming a safe enclosed or semi-enclosed high-altitude work space.

[0038] The platform main frame 84 has a bottom mounting frame 85 at its bottom, and the support bracket 82 is welded and fixed to the side wall of the bottom mounting frame 85. The bottom mounting frame 85 has a built-in adjustable guide rail 86 installed inside. The platform main frame 84 is movably mounted inside the built-in adjustable guide rail 86 through the bottom self-stabilizing control base 87. The adjustable ladder 81 is controlled by the electric control adjustment rod 88 and the self-stabilizing control base 87.

[0039] The self-stabilizing adjustment base 87 consists of a straight lead screw installed inside the built-in adjustment guide rail 86, an internal threaded translation seat threaded onto the straight lead screw, and a flipping support rod hinged to the internal threaded translation seat. The straight lead screw rotates to drive the internal threaded translation seat to translate along the built-in adjustment guide rail 86. Then, the electrically controlled adjustment rod 88 extends and retracts to control the connecting rod installed on one side of the adjustable ladder 81 to adjust, thereby changing the angle of the adjustable ladder 81.

[0040] By adjusting the angle of the support base 7, the maintenance platform 8 can always remain horizontal when someone is operating it, making it convenient for people to operate and move on it, and improving safety.

[0041] like Figure 2 The top device 9 is installed at the front end of the support base 7. During operation, it can extend and press against the rock surface of the slope to provide stable front-end support for the entire working device.

[0042] The top device 9 is designed with a built-in pressure sensor and a miniature hydraulic or piezoelectric ceramic actuator. During rock drilling operations, it can sense and counteract high-frequency vibrations and impacts from the rock surface in real time.

[0043] Traditional drill pins provide only passive support. This improvement transforms them into active vibration damping units, isolating the significant amounts of harmful vibrations generated during rock drilling from the main body of the working device. This greatly improves drilling accuracy, extends the service life of precision components within the device, and enhances operational comfort.

[0044] like Figure 1 , 3 The workstation switching device 5 is mounted on the support base 7 and can drive the rock drilling device 2, the anchor bolt device 3, and the grouting device 1. The grouting function is integrated into the anchor bolt device 3 and can be considered as part of it. It switches between the various support positions on the support base 7, so that the required functional device can be accurately moved to the working position in front. The compensation device 11 is used to connect the rock drilling device 2, the anchor bolt device 3, and the support base 7, providing necessary motion compensation.

[0045] The workflow of this invention is as follows: Positioning and Adjustment: The trolley travels to the work area and the boom delivers the working device to the vicinity of the slope. The operating range adjustment device 10 is used to ensure that the support base 7 and the device on it are basically perpendicular to the slope surface to be worked on. The extended tip device 9 is pressed against the rock surface to achieve positioning of the working device.

[0046] Drilling position: The position switching device 5 is activated, moving the rock drilling device 2 to the forward working position. The rock drill 21 and the propulsion device 23 are started to carry out drilling operations. After completion, the rock drilling device 2 retracts and moves out of the working position.

[0047] Grouting Station: The station switching device 5 activates, moving the anchor bolt device 3 to the working position and aligning the locking device 34 with and connecting it to the locking socket 32 ​​of the grouting inner tube 31. The telescopic device 38 drives the main tray 36 forward, pushing the grouting inner tube 31 into the drilled hole until it reaches the bottom. Grouting begins, while the main tray 36 slowly retracts to achieve retracted grouting, ensuring the hole is filled with grout. After grouting is completed, the device retracts.

[0048] Anchor rod retrieval and insertion station: First, the station switching device 5 moves the anchor rod device 3 to the retrieval position corresponding to the anchor rod magazine 4. The tightening device 35 aligns with the end of the anchor rod 37 to be retrieved on the anchor rod magazine 4 and screws it in partially for pre-tightening, while the gripper 312 grasps the front end of the anchor rod. The two work together to remove the anchor rod 37 from the anchor rod magazine.

[0049] Then, the clamping device 39 closes, clamping the anchor rod 37 from the middle. The inner cylinder of the tightening device 35 rotates, fully tightening its internal thread with the external thread at the tail end of the anchor rod 37. Subsequently, the clamping device 39 can be temporarily released.

[0050] Next, the workstation switching device 5 moves the anchor bolt device 3, which has already gripped the anchor bolt, to the forward anchor insertion position. The tightening device 35 drives the anchor bolt 37 to rotate, while the telescopic device 38 drives the main tray 36, advancing it forward along with the tightening device 35. During this process, the clamping device 39 closes again, providing stable intermediate support for the rotating and advancing anchor bolt 37, forming a stable pushing state with front, middle, and rear three-point support, effectively preventing the long anchor bolt from bending. The anchor bolt 37 is then pushed into the grouted hole until the designed depth.

[0051] Finally, clamping device 39 clamps the anchor bolt, tightening device 35 reverses and disengages from the tail end of the anchor bolt, and main tray 36 retracts. This completes a full cycle of drilling-grouting-anchoring.

[0052] A pressure sensor array is integrated into the jaws or pads of the clamping device 39 and connected to the control system. This allows it not only to "clamp" but also to "sense" the pressure distribution on different sides of the anchor bolt. When uneven pressure is detected, indicating that the anchor bolt is bending or misaligned with the borehole, the control system can dynamically adjust the clamping force of the jaws on both sides or actively correct the anchor bolt by fine-tuning the posture of the auxiliary tray 310. This solves the problem that traditional rigid clamping may exacerbate the jamming of bent anchor bolts, achieving adaptive and flexible pushing, and significantly improving the success rate of implanting ultra-long or easily deformable anchor bolts.

[0053] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
