Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction equipment, specifically relating to a muck removal device and a trolley. Background Technology

[0002] In the construction of some long tunnels, in order to shorten the construction period, inclined shafts are set up to increase the number of working faces. Originally a single construction direction can be opened up to new construction points through inclined shafts, and multiple working faces can be constructed at the same time, which greatly speeds up the tunnel breakthrough and effectively shortens the overall construction time.

[0003] Inclined shafts are inclined adit tunnels excavated during the construction of hydroelectric power station shafts (ventilation shafts, outlet shafts, drainage shafts, transport shafts), tunnels, and the laying of pressure pipelines. Due to the harsh underground construction environment and the significant inclination of the shaft, excavating inclined shafts is more difficult than excavating horizontal tunnels. Drilling and blasting methods are commonly used, with the most common method currently being the reverse shaft enlargement method. This method involves drilling a pilot hole from top to bottom, using a reverse shaft drilling rig to enlarge the hole through the pilot hole using an "up-down drilling" method, and then using pneumatic drills or rock drilling rigs to drill and blast in sections. After blasting, the excavated rock debris is shoveled into the pilot shaft. To efficiently excavate and clean up the rock debris and soil generated after blasting or mechanical excavation, a muck removal device is typically used. Besides cleaning up the rock debris and soil generated after blasting or mechanical excavation, the muck removal device can also transport the excavated materials to transport vehicles via a conveyor system, enabling rapid loading and facilitating material transportation, improving muck removal efficiency, and ensuring the smooth progress of tunnel construction. It can also operate flexibly in tunnel environments with narrow spaces and complex geological conditions, such as soft soil layers or strata containing a large amount of gravel, avoiding excessive damage to the surrounding environment and ensuring construction safety.

[0004] Existing muck-loading devices, due to the inherent limitations in the working range and angle of their robotic arms and buckets, struggle to cover all areas, such as the bottom edge and corners of tunnels, creating blind spots. These blind spots require manual labor or other equipment for supplementary work, increasing time and costs and reducing overall efficiency. Furthermore, manual handling of blind spots increases safety risks for operators due to the complex environment and lack of mechanized protection. Additionally, compensating for blind spots may lead to overuse of certain joints or components, accelerating wear and shortening equipment lifespan. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a slag removal device and trolley that can minimize the occurrence of blind spots in operation, have a large coverage of slag removal operation, remove slag accurately, and adapt to slag piles with different inclination angles in inclined shafts.

[0006] The technical solution of this utility model is as follows:

[0007] A slag removal device includes a frame, a first rotating mechanism disposed above the frame and rotating about a first axis; a second rotating mechanism connected to the first rotating mechanism and rotating about a second axis; and a boom connected to the other end of the second rotating mechanism for slag removal operations; the first axis and the second axis are perpendicular to each other in the same plane.

[0008] Preferably, the first slewing mechanism includes: a first base connected to the top of the frame; a first slewing drive assembly, one end of which is connected to the first base; and a conversion elbow connected to the first slewing drive assembly.

[0009] Preferably, the second slewing mechanism includes: a second slewing drive assembly, one end of which is connected to the conversion elbow, and the other end of which is connected to the boom.

[0010] Preferably, the boom includes: a first curved boom connected to the second slewing drive assembly; and a second curved boom hinged to the other end of the first curved boom.

[0011] Preferably, the device includes a telescopic mechanism, which comprises: a first drive mechanism that drives the frame to reciprocate along the second axis; a first pulley located below the frame; and a second pulley located above the frame.

[0012] Preferably, it includes a lifting mechanism for providing auxiliary support to the slag removal device.

[0013] Preferably, at least two lifting mechanisms are provided and installed on the frame.

[0014] Preferably, the lifting mechanism includes a hydraulic cylinder connected to the frame.

[0015] The second base is connected to the telescopic end of the hydraulic cylinder;

[0016] A top block, which is connected to the other end of the second base.

[0017] A trolley, including the aforementioned slag-removing device.

[0018] This utility model provides a slag removal device and trolley, including a frame, a first rotating mechanism located above the frame and rotating around a first axis; a second rotating mechanism connected to the first rotating mechanism and rotating around a second axis; and a boom connected to the other end of the second rotating mechanism, used for slag removal operations; the first axis and the second axis are perpendicular to each other in the same plane. The slag removal device provided in this application adopts a dual-rotating mechanism spatial motion logic. The first rotating mechanism is installed above the frame and rotates around the first axis (e.g., the Z-axis), driving the second rotating mechanism and the boom to achieve rotation in the horizontal plane (e.g., left-right swing); the second rotating mechanism is perpendicularly connected to the first rotating mechanism and rotates around a second axis perpendicular to the first axis (e.g., the X / Y axis), driving the boom to achieve pitching motion in the vertical plane (e.g., up-down swing). Because the first and second axes are perpendicular in the same plane (the Z-axis forms a rectangular coordinate system with the X / Y axes), the boom can achieve a combined action of "horizontal rotation and vertical pitch" in three-dimensional space through the coordinated movement of the double slewing mechanism, thereby covering any angle of the slag removal position within the inclined shaft. Existing slag removal devices can only operate in a single plane, and "slag removal dead angles" are easily formed at locations such as corners of the inclined shaft rock wall and edges of the guide tunnel. This application provides a slag removal device that, through the combined rotation of the Z-axis and X / Y-axis, allows the boom to flexibly extend into the angle between the inclined shaft rock wall and the guide tunnel, or adjust the slag removal angle along the inclined direction of the inclined shaft, significantly improving the coverage of dead angles. At the intersection of the inclined shaft and the guide tunnel, the boom can first rotate horizontally to align with the slag pile, and then adjust the bucket angle vertically to efficiently remove the slag into the guide tunnel. Therefore, the muck-removing device provided in this application, through its innovative design of a dual vertical rotary mechanism, upgrades planar motion to multi-degree-of-freedom spatial motion. Its core advantages lie in its strong ability to cover blind spots, flexible operating range, and stable structural rigidity. It is particularly suitable for complex working conditions such as pumped storage inclined shafts, which have narrow spaces and large inclination angles, providing an efficient solution for the multi-arm collaborative operation of integrated blasting and excavation trolleys. Thus, the muck-removing device and trolley provided in this application can minimize blind spots, achieve a large muck-removing coverage rate, precisely remove muck, and adapt to muck piles with different inclination angles in inclined shafts.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0028] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Figures 1 to 6As shown, this utility model provides a slag removal device, including a frame 1, a first rotating mechanism 2, which is located above the frame 1 and rotates around a first axis; a second rotating mechanism 3, which is connected to the first rotating mechanism 2 and rotates around a second axis; and a boom 4, which is connected to the other end of the second rotating mechanism 3 and is used for slag removal operations; the first axis and the second axis are perpendicular to each other in the same plane. The slag removal device provided in this application adopts a double rotating mechanism spatial motion logic. The first rotating mechanism 2 is installed above the frame 1 and rotates around the first axis (e.g., the Z-axis), driving the second rotating mechanism 3 and the boom 4 to achieve rotation in the horizontal plane (e.g., left and right swing); the second rotating mechanism 3 is perpendicularly connected to the first rotating mechanism 2 and rotates around a second axis (e.g., the X / Y axis) perpendicular to the first axis, driving the boom 4 to achieve pitching motion in the vertical plane (e.g., up and down swing). Since the first and second axes are perpendicular in the same plane (the Z-axis forms a rectangular coordinate system with the X / Y axes), the boom 4 can achieve a combined action of "horizontal rotation and vertical pitch" in three-dimensional space through the coordinated movement of the double rotary mechanism, thereby covering any angle of the slag removal position in the inclined shaft. Existing slag removal devices can only operate in a single plane, and "slag removal dead angles" are easily formed at the corners of the inclined shaft rock wall and the edges of the guide tunnel. The slag removal device provided in this application can flexibly extend into the angle between the inclined shaft rock wall and the guide tunnel through the combined rotation of the Z-axis and the X / Y-axis, or adjust the slag removal angle along the inclination direction of the inclined shaft, greatly improving the coverage of dead angles. At the intersection of the inclined shaft and the guide tunnel, the boom 4 can first rotate horizontally to align with the slag pile, and then adjust the bucket angle vertically to efficiently remove the slag into the guide tunnel. Therefore, the slag removal device provided in this application upgrades planar motion to spatial multi-degree-of-freedom motion through the innovative design of the dual vertical rotation mechanism. Its core advantages are strong dead angle coverage, flexible operating range, and stable structural rigidity. It is especially suitable for complex working conditions such as pumped storage inclined shafts with narrow spaces and large inclinations, and provides an efficient solution for multi-arm 4-cooperative operation of the blasting and excavation integrated trolley.

[0030] Furthermore, please see Figures 1 to 4As shown, the first slewing mechanism 2 includes: a first base 21, which is connected to the top of the frame 1; and a first slewing drive assembly 22, one end of which is connected to the first base 21 via a bend 23. The first base 21 serves as a basic support component, fixed to the top of the frame 1 by bolts or welding, providing an installation reference for the entire first slewing mechanism 2. Its structural design must meet torsional and compressive strength requirements to ensure that the first base 21 does not deform during rotation. The first slewing drive assembly 22 is connected to the first base 21 at one end, and to a bend joint via a shaft or flange at the other end. The drive assembly typically includes a hydraulic motor, a reducer, and transmission gears (such as worm gears or cylindrical gears). The motor is driven to rotate by hydraulic oil, and the speed is reduced and torque increased by the reducer before being transmitted to the output shaft. The turning joint has an L-shaped or right-angle structure. One end is fixed to the output shaft of the drive assembly, and the other end is connected to the second slewing mechanism 3 (or boom 4). Its function is to change the direction of power transmission, so that the second slewing mechanism 3 can rotate around a direction perpendicular to the first axis. The first base 21 is fixed to the top of the frame 1 by high-strength bolts. During operation, the slag removal reaction force conversion bend 23—drive assembly—first base 21 transmits the power to the frame 1, and then through the lifting and fixing mechanism to the inner wall of the trolley, forming a complete transmission path to prevent the mechanism from swaying. The output end of the conversion bend 23 is perpendicularly assembled to the input shaft of the second slewing mechanism 3 (i.e., the first axis is perpendicular to the second axis), so that the boom 4 can rotate horizontally while tilting vertically, realizing multi-degree-of-freedom movement in space. The first base 21 adopts a box-type structure or a reinforcing rib design, forming a surface contact fixation with the top of the frame 1. Compared with single-point support, the torsional stiffness is greatly improved, which can withstand the horizontal reverse conversion elbow 23 during slag removal. The elbow is connected to the drive component through a precision-machined shaft hole, ensuring that the power transmission has no significant loss and the rotation is smooth and without jamming. Therefore, in the embodiment provided in this application, the first slewing mechanism 2, through the mechanical structure design of the first base 21 supporting the drive transmission conversion elbow 23, realizes the full range coverage and precise control of the horizontal rotation of the boom 4. Its core advantages are strong rigid support capacity, high transmission efficiency, and good spatial adaptability. Especially when it is combined with the second slewing mechanism 3, it can significantly improve the multi-degree-of-freedom operation capability of the slag removal device, providing mechanical structural protection for the coordinated operation of multiple booms 4 and slag removal under complex working conditions in inclined shaft construction.

[0031] Preferably, the second slewing mechanism 3 includes: a second slewing drive assembly 31, with one end of the second slewing drive assembly 31 connected to a conversion elbow 23, and the other end of the second slewing drive assembly 31 connected to the boom 4. One end of the second slewing drive assembly 31 is vertically connected (perpendicular to the first axis) via a flange or shaft conversion elbow 23, and the other end is hinged or fixed to the root of the boom 4. The input end of the second slewing drive assembly 31 is vertically assembled with the output end of the conversion elbow 23, ensuring that the rotation axis (second axis) of the second slewing mechanism 3 is orthogonal to the axis (first axis) of the first slewing mechanism 2 in the same plane, forming a vertical degree of freedom in space. The vertical pitch of the second slewing mechanism 3 is linked with the horizontal rotation of the first slewing mechanism 2, allowing the boom 4 to be positioned arbitrarily in three-dimensional space. For example, the boom 4 can be horizontally rotated to the right side of the inclined shaft by the first slewing mechanism 2, and then the pitch angle can be adjusted by the second slewing mechanism 3 to insert the bucket into the slag heap at different heights. The second slewing mechanism 3, in conjunction with the horizontal rotation of the first slewing mechanism 2, allows the boom 4 to operate within a 360° horizontal and vertical spatial range. Compared to traditional muck-removing devices, this expands the three-dimensional operating range and improves muck-removing efficiency. Therefore, in the embodiments provided in this application, the second slewing mechanism 3, through its mechanical structure design of vertical drive, rigid support, and precise control, enables the boom 4 to flexibly pitch in the vertical plane. Its core advantage lies in solving the dead angle in the height direction, increasing the three-dimensional operating range, enhancing load-bearing capacity, and forming a dual-axis orthogonal rotation spatial degree of freedom with the first slewing mechanism 2. This provides key mechanical structural support for efficient muck-removing under complex conditions in inclined shafts, with significant advantages, especially in multi-boom 4 collaboration and high-angle environments.

[0032] In the embodiments provided in this application, the boom 4 includes: a first curved boom 41, which is connected to a second rotary drive assembly 31; and a second curved boom 42, which is hinged to the other end of the first curved boom 41. One end of the first curved boom 41 is fixedly connected to the output end of the second rotary drive assembly 31 via a flange or pin, and the other end is connected to the second curved boom 42 via a hinge shaft. The boom 4 has an overall L-shaped or arc-shaped structure, and its bending angle (e.g., 90° or 120°) is designed according to the space requirements of the inclined shaft construction, with the aim of avoiding interference from the trolley frame and expanding the working range. The second curved boom 42 is hinged to the first curved boom 41, and a shovel or other working component is installed at the other end of the second curved boom 42. A bearing or bushing is usually provided at the hinge point to allow the second curved boom 42 to rotate relative to the first curved boom 41, forming a foldable or extendable articulated structure. The hinge point can be driven by a hydraulic cylinder 61, an electric push rod, or a mechanical linkage to achieve the pitching motion of the second curved arm 42 relative to the first curved arm 41, or it can be fixed at a specific angle by a locking mechanism. This articulated structure provided in this application overcomes spatial limitations. Existing straight-arm muck-removing devices are limited by the size of the trolley frame and cannot penetrate deep into the recesses of the inclined shaft rock wall or the narrow areas of the guide tunnel, easily creating blind spots for muck removal. However, in this embodiment, the curved arm hinge structure allows the bending design of the first curved arm 41 to bypass other equipment in front of the trolley (such as the drilling boom 4), avoiding interference. The second curved arm 42 achieves a folding-extending motion through the hinge, reaching corners that the straight arm cannot reach. For example, at the T-shaped intersection of the inclined shaft and the guide tunnel, the boom 4 can first fold through the narrow passage and then extend to remove muck, further improving the coverage of blind spots. Therefore, the double-bend articulated boom structure of the boom 4 provided in this embodiment, through innovative mechanical design, upgrades the single pitch motion of the traditional straight boom to a combined rotation-articulation motion. Its core advantage lies in overcoming spatial limitations, expanding the operating range, and enhancing structural rigidity. This design, in conjunction with the first rotation mechanism 2 and the second rotation mechanism 3, achieves a technological leap from planar slag removal to three-dimensional, all-area operation.

[0033] Furthermore, the slag removal device includes a telescopic mechanism 5, which comprises: a first drive mechanism that drives the frame 1 to reciprocate along the second axis; a first pulley 51 located below the frame 1; and a second pulley 52 located above the frame 1. The first drive mechanism is typically a hydraulic cylinder 61 or a winch hoist, installed at the bottom of the frame 1 or on the trolley frame. The piston rod of the cylinder 61 or the wire rope of the winch is rigidly connected to the frame 1, driving the frame 1 to move along the second axis (X / Y axis) via hydraulic pressure or winch traction. The first pulley 51, located below the frame 1 and fixed to the trolley track or support structure, guides the wire rope or chain to prevent friction with the frame 1. The second pulley 52, located above the frame 1 and also fixed to the trolley frame, forms an upper and lower guide structure with the first pulley 51, ensuring the straightness of the frame 1 during telescopic movement. The telescopic mechanism 5 drives the frame 1 to move, cooperating with the vertical / horizontal rotation of the first slewing mechanism 2 to position the boom 4 in three-dimensional space. The first pulley 51 (below) and the second pulley 52 (above) form a vertical guiding constraint, controlling the lateral offset of the frame 1 during telescopic movement within a certain range to avoid collision with the trolley frame. The rigid support of the first pulley 51 and the second pulley 52 ensures smooth telescopic movement of the frame 1. Compared with the telescopic mechanism 5 without a guiding device, the vibration amplitude is reduced, ensuring the connection accuracy between the first slewing mechanism 2, the second slewing mechanism 3 and the boom 4. In the embodiment provided in this application, the mechanical design of the first drive mechanism and the upper and lower guide pulleys enables the slag removal device to flexibly telescopic in the horizontal direction. The advantages are that it expands the operating height range, ensures the stability of telescopic movement, and optimizes the collaborative work of multiple booms 4. This mechanism, in conjunction with the slewing mechanism and the curved boom structure, upgrades the slag removal device from fixed-height operation to full-area coverage, which is especially suitable for complex working conditions such as pumped storage inclined wells with large height variations and narrow spaces.

[0034] In the embodiments provided by this utility model, please refer to Figure 2As shown, the slag removal device includes a lifting mechanism 6, which provides auxiliary support for the slag removal device. After the telescopic mechanism 5 adjusts the frame 1 to the target position, the lifting mechanism 6 starts to tighten, forming a positioning-fixing operation process. In the tightened state, the reaction force of the slewing mechanism and the boom 4 is transmitted to the trolley through the lifting mechanism 6, preventing the slag removal device from shaking. When not in operation, the lifting mechanism 6 is retracted, cooperating with the telescopic mechanism 5, the first slewing mechanism 2, and the second slewing mechanism 3 to complete the slag removal device retraction, reducing spatial interference. Existing slag removal devices use single-point bolt fixing or simple supports, which are prone to swaying under force, thus affecting the slag removal accuracy. However, the slag removal device provided in this application has a slag removal reaction force—boom 4—first slewing mechanism 2, second slewing mechanism 3—lifting mechanism 6—trolley inner wall, with no flexible links throughout the entire process, greatly improving the force transmission efficiency. Compared with traditional cantilever support, the lifting mechanism 6 converts concentrated force into surface support force, avoiding local deformation of the trolley under force. On the other hand, when the reaction force of the cutting material increases suddenly, it can absorb the impact energy and protect the mechanical parts from damage. Therefore, in the embodiments provided in this application, the design of the double lifting mechanism 6 upgrades the traditional single-point support to a rigid surface support, significantly improving the stability of the cutting material removal device, optimizing the transmission path, and adapting to complex rock wall conditions. Especially in the construction of inclined shafts with large inclinations, it can effectively solve the problem of the cutting material removal device shaking during cutting, and provide reliable support for multi-arm collaborative operations. The linkage between this mechanism and the telescopic mechanism 5, the first rotating mechanism 2, and the second rotating mechanism 3 realizes the optimization of the entire process from rapid positioning to rigid fixing to efficient operation.

[0035] Specifically, at least two lifting mechanisms 6 are provided and installed on the frame 1. The lifting mechanism 6 includes: a hydraulic cylinder 61 connected to the frame 1; a second base 62 connected to the telescopic end of the hydraulic cylinder 61; and a top block 63 connected to the other end of the first base 21. The double-acting hydraulic cylinder 61 has its cylinder barrel fixed to the frame 1 via a flange or pin, and its piston rod extends and retracts in a direction perpendicular to the frame 1, providing power for the tightening action. The second base 62 is rigidly connected to the telescopic end (piston rod) of the hydraulic cylinder 61 and is typically a rectangular steel plate or box-shaped structure, used to transmit the thrust of the hydraulic cylinder 61 and support the top block 63. The top block 63 is installed at the other end of the second base 62 and can have its surface hardened (e.g., quenched or welded with a wear-resistant layer) and directly contact the inner wall of the trolley to form a support surface. The lifting mechanism 6, through the symmetrical arrangement of the double hydraulic cylinders 61, the second base 62 and the top block 63, upgrades the traditional single-point support to a rigid surface support system, which can significantly improve the stability of the slag removal device, optimize the force transmission path, and adapt to complex rock wall working conditions.

[0036] This application also provides a trolley, which includes the above-mentioned slag removal device and also possesses all the technical advantages of the slag removal device, which will not be described in detail here.
