Description

Technical Field

[0001] This application relates to the field of engineering equipment, and in particular to a multi-functional construction trolley. Background Technology

[0002] In tunnel construction, arch frames are a crucial component of initial support, primarily used to support the surrounding rock, prevent collapse, and, together with anchor bolts, steel mesh, and shotcrete, form a combined support system to ensure the stability of the tunnel structure. Arch frames (including steel arch frames and grid arch frames) are installed immediately after tunnel excavation, providing early support stiffness and preventing rock loosening and expansion of the plastic zone. Steel arch frames are rigid supports, effectively distributing most of the pressure from the surrounding rock, controlling deformation, and ensuring tunnel clearance. Modern tunnel construction widely utilizes trolleys equipped with robotic arms for arch frame installation. After the arch frames are installed, the subsequent anchoring process requires drilling holes in the tunnel wall and manually inserting anchor bolts into these holes. Since support is being installed at the work site, this poses a high safety risk to workers, and manual operation is inefficient. Utility Model Content

[0033] This application proposes a multi-functional construction trolley, referring to... Figures 1 to 4 The multi-functional construction trolley includes: a trolley body 10; a robotic arm 20, one end of which is mounted on the trolley body 10, and the free end of the robotic arm 20 is movable relative to the trolley body 10; a clamping mechanism 30, located at the free end of the robotic arm 20, for gripping the arch frame; and a conveying mechanism 40, located at the free end of the robotic arm 20 and on one side of the clamping mechanism 30, for driving the anchor rod to move along its own length.

[0034] In this embodiment, one end of the robotic arm 20 is mounted on the trolley body 10. It can be driven by hydraulic cylinders located inside or outside the robotic arm 20 to perform actions such as yaw, pitch, and extension. Thus, the free end of the robotic arm 20 can move relative to the trolley body 10 to adjust the position and orientation of the clamping mechanism 30 and the conveying mechanism 40. Furthermore, the clamping mechanism 30 at the free end of the robotic arm 20 can also use hydraulic cylinders to drive the jaws to open and close, grasping the arch frame. The free arm then drives the arch frame to move, allowing for arch frame installation inside the tunnel. The conveying mechanism 40 is used to drive the anchor bolts, automatically conveying them to holes in the tunnel wall during installation. The anchor bolt conveying process can be achieved using linear motor drive, hydraulic cylinder drive, or winch mechanism drive. Therefore, the multi-functional construction trolley can accommodate both arch frame installation and anchor bolt installation, improving equipment performance and solving the problem of low efficiency in manual anchor bolt installation.

[0035] In this embodiment, for anchor bolts of 6 meters, 9 meters or even longer, where traditional manual construction would be extremely difficult, the conveying mechanism of this application can convey longer anchor bolts more quickly and safely, replacing manual labor with fewer personnel. This allows for lifting, adjusting the direction of the anchor bolt, and pushing it into the drilled hole, significantly improving construction efficiency, quality, and safety.

[0036] In some embodiments, the conveying mechanism 40 includes: a base 41; an anchor rod guide assembly including a limiting seat 42 disposed on the base 41, the limiting seat 42 being used to install the anchor rod and being slidably connected to the anchor rod, and the sliding direction being along the length direction of the anchor rod; a drive assembly including a drive member disposed on one side of the anchor rod guide assembly and a connecting seat 45 connected to the drive end of the drive member, the connecting seat 45 being used to abut one end of the anchor rod, and the drive member being used to drive the anchor rod to slide along its own length direction.

[0037] In this embodiment, the anchor guide assembly includes a limiting seat 42 disposed on the base 41. When installing the anchor rod into the hole in the tunnel wall, the anchor rod can first be placed in the limiting seat 42. By controlling the movement of the robotic arm 20, one end of the anchor rod is aligned with the hole. Then, the connecting seat 45 is connected to the other end of the anchor rod. The driving assembly drives the connecting seat 45 to move, thereby pushing the anchor rod to slide along its own length and insert into the hole, realizing automatic insertion of the anchor rod. In this embodiment, the limiting seat 42 can be an annular limiting seat 42, and the anchor rod can be inserted into the annular limiting seat 42 to achieve radial limiting. The driving assembly can be driven by a motor, or by a hydraulic cylinder or a winch 43, etc., depending on the specific construction environment.

[0038] Furthermore, one end of the base 41 is hinged to the free end of the robotic arm 20; the conveying mechanism 40 also includes a first drive cylinder 51 connecting the robotic arm 20 and the base 41, the first drive cylinder 51 being used to drive the base 41 to rotate around the hinge point. The first drive cylinder 51 can be a hydraulic cylinder, which can drive the entire conveying mechanism 40 to rotate, increasing the degree of freedom of the conveying mechanism 40 to adjust the angle between the anchor rod and the tunnel wall, making it suitable for inclined drilling holes.

[0039] Furthermore, the robotic arm 20 includes a telescopic arm 21 with one end hinged to the trolley body 10, and an angle-adjusting arm 22 hinged to the end of the telescopic arm 21 away from the trolley body 10. The telescopic arm 21 is mainly used to lift the arch frame and anchor rods, while the angle-adjusting arm 22 can be used to adjust the posture of the arch frame and anchor rods. The telescopic arm 21 and the arch frame can be driven by external hydraulic cylinders. A leveling arm 23 can also be provided between the telescopic arm 21 and the angle-adjusting arm 22. The leveling arm 23 is L-shaped, with one end hinged to the free end of the telescopic arm 21. A basket (not marked in the figure) is mounted on the upper side of the leveling arm 23. This is mainly used to keep the basket flat. The angle-adjusting arm 22 is hinged to the end of the leveling arm 23 away from the telescopic arm 21, and can be considered as the free end of the robotic arm 20. The clamping mechanism 30 and the conveying mechanism 40 are respectively located on both sides of the angle adjusting arm 22, and can adjust their posture as the angle adjusting arm 22 swings. They can also be positioned on opposite sides of the angle adjusting arm 22 to maintain balance and ensure sufficient installation space. Furthermore, the multi-functional construction trolley includes a second drive cylinder 52 connecting the clamping mechanism 30 and the angle adjusting arm 22. The second drive cylinder 52 is used to drive the clamping mechanism 30 to rotate. The second drive cylinder 52 can also be used to adjust the posture of the clamping mechanism 30.

[0040] In some embodiments, the clamping mechanism 30 is located on the side of the angle adjusting arm 22 away from the center of the trolley body 10, and the conveying mechanism 40 is located on the side of the angle adjusting arm 22 closer to the center of the trolley body. During arch frame installation, the first drive cylinder 51 drives the conveying mechanism 40 to retract to the side of the angle adjusting arm 22, preventing the conveying mechanism 40 from interfering with the gripping and installation of the arch frame. During anchor bolt installation, the second drive cylinder 52 drives the clamping mechanism 30 to retract to the side of the angle adjusting arm 22, preventing the clamping mechanism 30 from interfering with the gripping and installation of the anchor bolt, and preventing the clamping mechanism 30 from touching the tunnel wall or the arch frame; in general, this avoids motion interference.

[0041] In some embodiments, the driving component includes a winch 43 mounted on a base 41 and a traction cable 44, one end of which is partially wound around the winch 43 and the other end of which is connected to a connecting seat 45. Through the cooperation of the winch 43 and the traction cable 44, stable traction or pushing of the anchor bolt can be achieved, suitable for the installation requirements of long-distance or large-diameter anchor bolts. The winch 43 has a simple structure, is easy to maintain, and has controllable traction force, making it suitable for various construction scenarios. The aforementioned traction cable 44 can also be made of steel cable to suit high-humidity construction environments, while also possessing strong mechanical properties.

[0042] Furthermore, multiple anchor guide assemblies are spaced apart on the base 10, with the anchor guide assembly closest to the winch 43 having a height higher than the winch 43. Two anchor guide assemblies can be spaced apart on the base 41, arranged along the length of the base 10. Using the base 10 as a reference, the limiting seat 42 near the winch 43 is positioned higher than the winch 43, allowing the anchor bolt to be higher than the winch 43, providing the winch 43 with a higher installation space to avoid obstructing the anchor bolt and facilitating construction. The two anchor guide mechanisms are spaced apart, ensuring the anchor bolt can only slide along its length, and facilitating accurate alignment with the hole.

[0043] In some embodiments, the conveying mechanism 40 further includes a rope guide assembly 46. The winch 43 is located at one end of the base 41, the rope guide assembly 46 is located at the other end of the base 41, and the anchor rod guide assembly is located in the middle section of the base 41. The rope guide assembly 46 guides the traction cable 44. The rope guide assembly 46 effectively adjusts the angle between the traction cable 44 and the anchor rod to less than 30 degrees, thereby allowing the tension applied by the traction cable 44 to have a larger axial component, which is used to push and pull the anchor rod, improving traction efficiency.

[0044] In some embodiments, one end of the traction cable 44 is connected to the winch 43, and the other end passes through two supports and the rope guide assembly 46 in sequence, and is connected to the connecting seat 45. This arrangement makes the anchor bolt and the traction cable 44 coplanar, resulting in more balanced force distribution and preventing the anchor bolt from tilting or jamming due to eccentric force. At the same time, the traction cable 44 is also protected by the supports and the rope guide assembly 46, reducing wear and extending its service life.

[0045] In some embodiments, the rope guiding assembly 46 includes a guide wheel and a guide roller disposed outside the guide wheel, with the traction cable 44 disposed between the guide wheel and the guide roller. The outer periphery of the guide wheel is provided with a rope groove, which enables bidirectional limiting of the traction cable 44, preventing the traction cable 44 from deviating or jumping out of the groove during traction, thereby improving the stability and reliability of the entire drive system.

[0046] In some embodiments, the connecting seat 45 includes a sleeve with one open end for docking with the anchor rod and the other closed end; the sleeve is also connected to the end of the traction cable 44. The open end of the sleeve can fit tightly with the end of the anchor rod to ensure that the anchor rod will not fall off during traction, while the closed end is connected to the traction cable 44, resulting in a stable structure and uniform stress distribution, suitable for high-intensity operation scenarios. Furthermore, a sea serpent welded connecting ring is provided on the outer wall of the sleeve for connecting the steel cable. The steel cable and the connecting ring can be connected by a locking hook, allowing for quick assembly and disassembly. Anti-loosening screws can also be provided through the outer wall of the sleeve. Specifically, threaded holes can be provided radially on the side wall of the sleeve. After screwing in the anti-loosening screw, it can be inserted into the radial through hole at the tail end of the anchor rod or directly abut against the anchor rod, forming a secondary safety measure to prevent the anchor rod from falling off during the advancement process.

[0047] In some embodiments, the conveying mechanism 40 further includes a docking portion 48 and a protective plate 47 disposed at one end of the base 41. The docking portion 48 is used to dock with the end of the anchor rod. The protective plate 47 is disposed between the docking portion 48 and the driving member. In this embodiment, the driving member can be a winch 43. When the docking portion 48 faces upward and docks with the exposed section of the anchor rod, the protective plate 47 is used to protect the winch 43 below, preventing the anchor rod from touching the winch and causing damage to the winch 43 when the docking portion 12 deviates from docking. In addition, the protective plate 48 can also prevent sand and gravel on the upper rock wall from falling into the winch 43 and causing damage. Of course, the above-mentioned protective plate 48 can also be configured as a shell structure to further improve the protective effect on the winch 43.

[0048] In some embodiments, the limiting seat 42 includes a first semi-ring member disposed on a bracket, and a second semi-ring member with one end hinged to the first semi-ring member, the first and second semi-ring members being joined to form a ring; the other ends of the first and second semi-ring members are detachably connected. The other ends of the first and second semi-ring members can be locked with screws. When the anchor rod is disengaged from the limiting seat 42, the locking of the first and second semi-ring members can be released, and the second semi-ring member can be flipped to open the limiting seat 42, facilitating the separation of the anchor rod. This structure facilitates quick assembly and disassembly of the anchor rod, improving construction efficiency. Alternatively, rollers can be installed on the inner walls of the two semi-ring members to guide the anchor rod and reduce friction.

[0049] It is worth noting that the conveying mechanism 40 can be mounted on the angle adjustment arm 22 of the arch frame / arch anchor trolley, or on the boom of other tunnel construction trolleys. Adding this mechanism to the arch frame and arch anchor makes better use of the installation space and adds new functions to the arch frame / arch anchor trolley. This mechanism can replace manual labor more quickly and safely with less personnel to lift the anchor rod, adjust its direction, and push it into the drilled hole.

[0050] In some embodiments, the multi-functional construction trolley includes multiple robotic arms 20, each robotic arm 20 having at least one of a clamping mechanism 30 and a conveying mechanism 40 at its free end. Specifically, two robotic arms 20 can be provided, namely, a first robotic arm 201 and a second robotic arm 202. Both the first robotic arm 201 and the second robotic arm 202 have a clamping mechanism 30 and a conveying mechanism 40 at their free ends. The clamping mechanism 30 is located on the inner side of the first robotic arm 201 and the second robotic arm 202 when they are close to each other, and on the outer side of the first robotic arm 201 and the second robotic arm 202 when they are far apart from each other. The first robotic arm 201 and the second robotic arm 202 can be used to clamp the arch frame respectively, completing the assembly and installation of the arch frame. This is suitable for two-section arch frame installation conditions. The clamping mechanism 30 and conveying mechanism 40 on the first robotic arm 201 are mirror images of the clamping mechanism 30 and conveying mechanism 40 on the second robotic arm 202. This layout is more reasonable, as the inner conveying mechanism 40 still has room to move after the arch frame installation is completed, allowing for anchor bolt conveying. The coordinated operation of multiple robotic arms 20 can improve the installation efficiency of both the arch frame and the anchor bolts.

[0051] Of course, a third robotic arm (not shown in the figure) can be added based on the previous embodiment. The third robotic arm is located between the first robotic arm 201 and the second robotic arm 202, and a clamping mechanism 30 is provided at the free end of the third robotic arm. This structure is suitable for the installation of a three-section arch frame, with the third robotic arm used to install the top arch frame. The free end of the third robotic arm does not need to be equipped with a conveying mechanism 40. After the arch frame is fixed, the anchor bolts near the top of the tunnel can be conveyed through the conveying mechanisms 40 on the other two robotic arms 20. The coordinated operation of multiple robotic arms 20 can improve the installation efficiency of the arch frame and the anchor bolts.

[0052] In this embodiment, the workflow of the tunnel construction equipment is as follows:

[0053] The quick installation method for anchor bolts involves lowering the telescopic boom 21 to its lowest position, leveling the angle adjusting arm 22, loosening the screws to allow the two semi-rings to flip relative to each other, thus opening the two limiting seats 42. The anchor bolt is then manually inserted radially into the limiting seats 42, and the screws are tightened to assemble the two semi-rings, completing the anchor bolt's positioning. The connecting seat 45 at the head of the wire rope is then fitted onto the tail end of the anchor bolt. The winch 43 pre-tensions the wire rope. At this point, the anchor bolt is radially limited (guided) by the two limiting seats 42 and axially limited by the wire rope of the winch 43, effectively making the anchor bolt fully positioned.

[0054] At this point, by using the swaying, pitching, and telescopic movements of the telescopic boom 21, and the swaying and pitching movements of the angle adjusting boom 22, the anchor rod can be positioned ideally aligned with the anchor hole. Then, the winch 43 is driven to retract the wire rope, and the tail end of the anchor rod is lifted upwards through the connecting seat 45, thus conveying the anchor rod into the anchor hole.

[0055] When the connecting seat 45 approaches the wire rope guide wheel, further lifting will be impossible. At this point, personnel inside the suspended platform manually open the limiting seat 42 to release the anchor rod. The platform is then lowered, and the tail of the anchor rod is held in place by the limiting groove on the protective top plate. Finally, the telescopic boom 21 pushes the last section of the anchor rod into the hole to complete the construction. During this process, only minimal manual assistance is required, significantly reducing workload and manpower compared to fully manual construction. The effect is even more pronounced for longer anchor rods.

[0056] Especially for longer anchor bolts, such as 6 meters, 9 meters, or even longer, the bolts are heavier and require more personnel to assist in lifting, guiding, and pushing them into the hole. When using this conveyor mechanism, the lifting, guiding, and pushing of the anchor bolts into the hole are all done mechanically. Compared to existing manual construction methods, this significantly improves construction efficiency, quality, and safety, reduces the number of personnel, and greatly reduces the workload of manual labor.

[0057] The above are only some or preferred embodiments of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
