Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction, specifically relating to an arch frame transport device and a trolley. Background Technology

[0002] Tunnels can traverse natural obstacles such as mountains and rivers, avoiding the problem of excessively long routes caused by detours, thereby shortening travel distances and improving transportation efficiency. For example, railway tunnels reduce the resistance of trains climbing slopes by using straight tracks, thus increasing operating speeds; while urban tunnels alleviate surface traffic congestion and optimize road network structures.

[0003] Among them, the arch frame plays a crucial supporting and protective role in tunnel construction, and is an important component to ensure tunnel construction safety and structural stability. The main functions of the arch frame include providing support resistance, enhancing support effect, adapting to different surrounding rock conditions, and also providing a platform for tunnel construction, facilitating other operations for workers, such as installing steel mesh and shotcreting.

[0004] As the core structure of the initial support, the arch frame needs to be installed within two hours of excavation to quickly provide rigid support and prevent the surrounding rock from loosening, deforming, or collapsing. If transportation is not timely, the pressure release of the surrounding rock may become uncontrollable after support is installed, leading to safety hazards. On the other hand, after tunnel excavation, the surrounding rock is in a dynamic stress adjustment stage, and the timely installation of the arch frame can effectively suppress the displacement of the surrounding rock. However, traditional manual handling of the arch frame is labor-intensive and inefficient.

[0005] Therefore, how to improve the efficiency of arch frame transportation is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0025] 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.

[0026] 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.

[0027] Figures 1 to 4 As shown, this utility model provides an arch frame transport device. The arch frame transport device is located on one side of the lifting device 1 and is used to transport the arch frame on the lifting device 1. The arch frame transport device includes: a lifting assembly 2, which moves up and down in the vertical direction; a first telescopic assembly 3, which is located on one side of the lifting assembly 2 and extends and retracts along the conveying direction of the arch frame transport device, and extends to below the arch frame on the lifting device 1; and a second telescopic assembly 4, which is located on the other side of the lifting assembly 2 and extends and retracts along the conveying direction of the arch frame transport device.

[0028] The arch frame transport device provided in this application completes the entire process of grabbing, transferring, and positioning the arch frame between the lifting device 1 and the installation position through the coordinated action of the lifting component 2, the first telescopic component 3, and the second telescopic component 4. Specifically, the lifting component 2, as the core module for vertical movement, realizes vertical lifting and lowering, and its main functions include: lifting the arch frame to a safe height and accurately transferring the arch frame to the second telescopic component 4; the first telescopic component 3, as the input side, is located on one side of the lifting component 2 and can achieve horizontal extension and retraction, specifically: extending to grab the arch frame to be transported under the lifting device 1 and retracting to transfer the arch frame to the working range of the lifting component 2; in addition, the second telescopic component 4, as the output side, is located on the other side of the lifting component 2, and can be structurally symmetrical with the first telescopic component 3, undertaking the tasks of: receiving the arch frame below the lifting component 2 and extending to the installation position to complete the release of the arch frame. The entire workflow is as follows: the first telescopic component 3 extends to the underside of the arch frame of the lifting device 1 to complete the arch frame grabbing - the first telescopic component 3 retracts - the lifting component 2 lifts - moves to the target position - the lifting component 2 descends to the height of the second telescopic component 4 and the lifting component 2 releases the arch frame - the second telescopic component 4 extends to the installation position.

[0029] The arch frame transport device provided in this application adopts a three-dimensional spatial layered layout. The first telescopic component 3 and the second telescopic component 4 move upward along the horizontal X-axis, while the lifting component 2 moves along the vertical Z-axis. Through this three-dimensional staggered layout, the overlapping area of ​​projections is reduced, and the total width is compressed. Furthermore, a strict interlocking logic is used, for example, prohibiting the movement of the first telescopic component 3 and the second telescopic component 4 until the lifting component 2 reaches a safe height, thus completely eliminating the risk of collision. Therefore, the arch frame transport device provided in this application not only improves transport efficiency but also, through the core design of dual-platform time-sharing collaboration and the transfer via the lifting component 2, enables efficient transport and installation of arch frames within a compact space, such as a drilling and anchoring integrated machine. It also solves the pain points of mechanical interference and low efficiency in traditional solutions, providing an innovative and efficient construction solution for mechanized tunnel construction.

[0030] Ideally, please refer to Figure 3 As shown, the lifting assembly 2 includes: a translation frame 21, with a sliding pair between the translation frame 21 and the translation guide rail; a lifting platform 22, which is located above the translation frame 21, and a first telescopic assembly 3 and a second telescopic assembly 4 are respectively located on both sides of the lifting platform 22. The technical solution provided in this application achieves a three-dimensional composite motion of horizontal translation, vertical lifting, and bilateral telescopic extension through a vertically layered mechanism consisting of a translation frame 21, a lifting platform 22, and two side first telescopic components 3 and 4. The specific action flow is as follows: 1. Horizontal positioning: The translation frame 21 moves on the translation guide rail via a sliding pair, horizontally transporting the lifting platform 22 to the target area. The sliding pair can be a high-precision linear guide rail. 2. Vertical lifting: The lifting platform 22 achieves vertical lifting and lowering via a hydraulic cylinder or ball screw, grabbing or releasing the arch frame. 3. Bilateral coordinated extension and retraction: The first telescopic component 3 and the second telescopic component 4 can be driven by a gear rack or hydraulic cylinder, extending horizontally from both sides of the lifting platform 22. The first telescopic component 3 is responsible for receiving the arch frame from the lifting device 1; the second telescopic component 4 is responsible for transporting the arch frame to the installation position. The technical solution provided in this embodiment separates horizontal and vertical movements. The translation frame 21 only undertakes the horizontal movement function (X-axis), while the lifting platform 22 independently completes the vertical movement (Z-axis). This layered design eliminates the mechanical interference caused by the combined movements in traditional solutions. Furthermore, the first telescopic component 3 and the second telescopic component 4 are respectively arranged on both sides of the lifting platform 22, with spatial isolation between them. This physical isolation avoids the risk of collision during simultaneous extension. Therefore, in this embodiment, through this layered design and innovative structure of dual-sided collaborative operation, the lifting component 2 successfully solves the problem of transporting the steel frame of the drilling and anchoring machine in a confined space, achieving a leapfrog improvement in core indicators such as operating efficiency, space utilization, and reliability.

[0031] The lifting platform 22 includes: a first base 221, the bottom of which is connected to the translation frame 21; a first telescopic rod 222, the first base 221 being sleeved on the outside of the first telescopic rod 222, the first telescopic rod 222 extending and retracting in the vertical direction; and a first lifting platform 223, the bottom of which is connected to the first telescopic rod 222. In this embodiment, the lifting platform 22 achieves vertical movement through a three-layer nested structure of the first base 221, the first telescopic rod 222, and the first lifting platform 223, as follows: 1. The first base 221 serves as a fixed reference component, with its bottom rigidly connected to the translation frame 21 (bolts or welding). The first telescopic rod 222 is sleeved on the outside of the first base 221, providing vertical movement guidance. In addition, the first base 221 can also bear the overall weight of the lifting platform 22; 2. The first telescopic rod 222 is nested inside the first base 221 and is driven to extend vertically by a hydraulic cylinder / ball screw. The first telescopic rod 222 adopts a multi-stage sleeve structure (such as 3-stage extension, with each stage having a stroke of 0.5m) to improve stability; 3. The first lifting platform 223 is connected at the bottom to the top of the first telescopic rod 222, directly bearing the weight of the arch frame. It can also integrate an tilt sensor to achieve automatic leveling. In the vertical direction, the vertical load transfer path is: arch frame gravity—first lifting platform 223—first telescopic rod 222—first base 221—translation frame 21. In the embodiments provided in this application, the design of the nested sleeve structure and high-precision guidance system improves the space utilization, positioning accuracy and reliability of the lifting platform 22, providing key technical support for mechanized tunnel construction.

[0032] Please Figure 4 As shown in the embodiment provided in this application, the first telescopic component 3 includes a first telescopic platform 31, a first telescopic guide rail 32, one end of the first telescopic guide rail 32 being fixedly connected to the first telescopic platform 31 to drive the first telescopic platform 31 to reciprocate; and a first fixed frame 33, which is disposed above the first telescopic platform 31 and used to fix the arch frame. The first telescopic platform 31 carries the arch frame and completes the horizontal telescopic movement. The first telescopic guide rail 32 can be driven by a hydraulic cylinder or by a rack and pinion transmission. The first fixed frame 33 can be equipped with positioning mechanisms, such as V-shaped slots to adapt to H-shaped arch frames, or hydraulic grippers, etc. Furthermore, it can incorporate anti-deviation designs, such as adjustable limit baffles on both sides and friction coefficient enhancement treatments. Through precise control and space optimization design, the first telescopic component 3 achieves a dual breakthrough in efficiency and reliability in arch frame transportation scenarios.

[0033] The system includes at least two parallel first telescopic guide rails 32. The symmetrical arrangement of these two rails forms a stable triangular support structure, allowing vertical and horizontal loads to be evenly transferred to the next process via the two first telescopic guide rails 32. Furthermore, the dual guide rails create a dual-degree-of-freedom constraint, limiting the lateral offset of the telescopic platform in the transverse direction (Y-axis) and restricting its pitch swing (rotation around the X-axis). Therefore, the parallel design and dynamic synchronous control of the two first telescopic guide rails 32 enable this technical solution to achieve a triple breakthrough in arch frame transportation accuracy, efficiency, and reliability under the extreme spatial constraints of the drilling and anchoring machine, laying a solid technical foundation for mechanized tunnel construction equipment.

[0034] Please Figure 4 As shown in the embodiment provided in this application, the second telescopic component 4 includes a second telescopic platform 41, a second telescopic guide rail 42, one end of which is fixedly connected to the second telescopic platform 41 to drive the second telescopic platform 41 to reciprocate; and a second fixed frame 43, which is disposed above the second telescopic platform 41 and used to fix the arch frame. In this embodiment, the second telescopic platform 41 carries the arch frame and completes horizontal telescopic movement, forming a bidirectional alternating working channel with the first telescopic platform 31. The second telescopic guide rail 42 is rigidly connected to the second telescopic platform 41. In addition, the second fixed frame 43 can adopt an adaptive clamping mechanism to fix arch frames of different specifications (such as H-beams, U-beams, etc.) to prevent the arch frame from shifting during transportation. In this embodiment, through the technical route of bidirectional collaborative operation, the second telescopic component 4 achieves a triple breakthrough in efficiency, accuracy, and reliability in the arch frame transportation scenario, providing basic support for mechanized tunnel construction under complex geological conditions.

[0035] Furthermore, at least two second telescopic guide rails 42 are arranged side by side. The symmetrical arrangement of the two parallel guide rails forms a stable triangular support structure, and vertical and horizontal loads are evenly transferred to the next process through the two second telescopic guide rails 42. On the other hand, the dual guide rails create a dual-degree-of-freedom constraint, limiting the lateral offset of the telescopic platform in the transverse direction (Y-axis direction) and limiting pitch oscillation (rotation around the X-axis). Therefore, the side-by-side design of the dual guide rails and the dynamic synchronous control of the synchronized movement of the two second telescopic guide rails 42 enable this technical solution to achieve a triple breakthrough in arch frame transportation accuracy, efficiency, and reliability under the extreme spatial constraints of the drilling and anchoring integrated machine.

[0036] In the embodiments provided by this utility model, the arch frame transport device includes a drive assembly 5, which drives the first telescopic guide rail 32 and the second telescopic guide rail 42 to reciprocate. The power source for the drive assembly 5 can be a hydraulic pump station or a servo motor unit, selected according to load requirements. The transmission mechanism of the drive assembly 5 can be a gear rack / ball screw (high precision) or a hydraulic cylinder (high thrust). This dual-guide rail coordinated drive, using a rigid synchronous shaft connected to the first telescopic assembly 3 and the second telescopic assembly 4, ensures balanced force on both sides.

[0037] In the embodiments provided by this utility model, a trolley is provided, including the aforementioned arch frame transport device. It also possesses all the technical advantages of the specific embodiments of all the aforementioned arch frame transport devices, which will not be repeated here.

[0038] Preferably, the trolley includes a lifting device 1 located on one side of the arch frame transport device. The lifting device 1 includes a first lifting assembly 11 and a support platform 12. One end of the support platform 12 is connected to the first lifting assembly 11, and a sliding pair is provided between the first lifting assembly 11 and the support platform 12. The support platform 12 is used to lift the arch frame and move it above the first telescopic assembly 3. When the arch frame needs to be transported, the first lifting assembly 11 drives the support platform 12 to rise and fall vertically, lifting the arch frame above the first telescopic assembly 3. The first telescopic assembly 3 extends along the conveying direction to below the lifting device 1, grabbing and transporting the arch frame.
