Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction, specifically relating to an arch frame transverse transport device and 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] When erecting arch frames after tunnel blasting, the frames need to be transported to the tunnel face for manual assembly, which is time-consuming, has low time utilization, and involves high labor intensity. Furthermore, workers face significant dangers while operating at the tunnel face. Therefore, some construction projects currently use folding arch frames. However, this presents a new problem: how to transport the folding arch frames to the tunnel face and unfold them without interfering with the already installed arch frames. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an arch frame transverse transport device and trolley that can prevent interference with the installed arch frame during the transport of folded arch frames.

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

[0007] A transverse transport device for an arch frame includes a frame; a lifting device located on one transverse side of the frame for lifting a folded arch frame to a preset height; a guiding mechanism located on the radial side of the frame, the guiding mechanism having a first state of contacting the inner side of the folded arch frame after rotation; a track assembly located in a transverse direction away from the guiding mechanism, the track assembly and the folded arch frame having a sliding pair; a lifting mechanism for lifting and gripping the folded arch frame onto the track assembly; and an unfolding mechanism located at the other end of the track assembly, wherein when the folded arch frame slides through the track assembly to the unfolding mechanism, the unfolding mechanism unfolds the folded arch frame by rotation.

[0008] Preferably, the guiding mechanism includes: a base, which is fixedly disposed; a first rotating shaft, which is disposed on the base; a first support arm, which is connected to the base and rotates through the first rotating shaft; and a guide round end, which is disposed at the end of the support arm away from the first rotating shaft and contacts the inner side of the folding arch frame.

[0009] Preferably, the unfolding mechanism includes: a second rotating shaft rotatably connected to the frame; a second support arm rotatably connected to the second rotating shaft, with an open circular end that contacts the folding arch frame.

[0010] Preferably, the track assembly includes an upper track, the upper track including a first track body fixedly connected to the frame; and a first guide shaft, which is alignable with the guide round end and contacts the inner side of the folding arch frame.

[0011] Preferably, the track assembly includes a lower track, the lower track including a second track body fixedly connected to the frame; and a second guide shaft, the second guide shaft contacting the inner side of the folding arch frame, the second guide shaft being alignable with the guide round end, and the second guide shaft being parallel to the first guide shaft.

[0012] Preferably, two sets of track assemblies are symmetrically arranged on both sides of the frame.

[0013] Preferably, the second guide shaft is aligned with the end of the guide circle and the end of the unfolded circle.

[0014] Preferably, the outer contours of the guide round end and the unfolding round end are adapted to the inner shape of the folding arch frame.

[0015] Preferably, the lifting device includes: a first lifting assembly and a support platform, one end of which is connected to the first lifting assembly, and a sliding pair is provided between the first lifting assembly and the support platform. The support platform is used to lift the arch frame and move it onto the guide mechanism.

[0016] A trolley includes the aforementioned arched transverse transport device.

[0017] This utility model provides a transverse transport device for an arch frame, including a frame; a lifting device located on one transverse side of the frame for lifting the folded arch frame to a preset height; a guiding mechanism located on the radial side of the frame, having a first state of contact with the inner side of the folded arch frame after rotation; a track assembly located in the transverse direction away from the guiding mechanism, with a sliding pair between the track assembly and the folded arch frame; a jacking mechanism for jacking and gripping the folded arch frame onto the track assembly; and a unfolding mechanism located at the other end of the track assembly, which unfolds the folded arch frame by rotation when it slides through the track assembly to the unfolding mechanism. This technical solution addresses the complex scenario of arch frame transport and unfolding in tunnel construction by providing a mechanical structure collaborative control solution. Its core lies in achieving precise path control of the folded arch frame from transport to unfolding state through the cooperation of a rotatable guiding mechanism and a track assembly, thereby improving transport efficiency by replacing manual adjustments with mechanical structures. Secondly, the coordination between the unfolding mechanism and the track assembly enables the arch frame to transform its shape within a limited space. Thirdly, the coordinated action of the lifting mechanism, track assembly, guiding mechanism, and unfolding mechanism allows the arch frame to move along the tunnel side, avoiding the space limitations of the integrated drilling and anchoring machine. The specific working principle is as follows: After the transport vehicle transports the folded arch frame to the designated position, the lifting device is activated to lift the folded arch frame. Simultaneously, the guiding mechanism rotates, switching to the first state of contact with the inner side of the folded arch frame. The lifting device grabs the folded arch frame and moves it along the track assembly until it reaches the unfolding mechanism. Upon reaching the unfolding mechanism, the unfolding mechanism rotates, and the folded arch frame unfolds, completing the transformation of its working shape. The rotation and guidance of the guiding mechanism ensures that the folded arch frame will not interfere with the installed arch frame during transportation. The guiding mechanism's first state of contact with the inner side of the folded arch frame ensures that the folded arch frame moves along the correct path. The track assembly is designed to ensure the stability of the folded arch frame during movement and to ensure that the folded arch frame will not interfere with other structures when unfolded. Furthermore, the unfolding mechanism only rotates and unfolds after the folding arch reaches the designated position, ensuring that the folding arch can be safely unfolded to its working state and avoiding collisions with surrounding structures. Therefore, this technical solution, through the design of the guiding mechanism and track assembly, ensures that the folding arch makes reasonable use of space during transportation and unfolding, avoiding interference with other structures. The coordination of the guiding mechanism, track assembly, lifting mechanism, and unfolding mechanism ensures that the folding arch will not collide with installed arches or other structures during movement and unfolding, improving operational safety. This utility model also provides a trolley, including the aforementioned lateral transport device for the arch, which also possesses the above-mentioned technical effects.

[0029] 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.

[0030] 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.

[0031] Figures 1 to 9 As shown, this utility model provides a transverse transport device for an arch frame, including a frame 1; a lifting device 2, located on one transverse side of the frame 1, used to lift the folded arch frame to a preset height; a guiding mechanism 3, located on the radial side of the frame 1, having a first state of contacting the inner side of the folded arch frame after rotation; a track assembly 4, located in the transverse direction away from the guiding mechanism 3, with a sliding pair between the track assembly 4 and the folded arch frame; a lifting mechanism 5, used to lift and grasp the folded arch frame onto the track assembly 4; and an unfolding mechanism 6, located at the other end of the track assembly 4, which unfolds the folded arch frame by rotation when the folded arch frame slides through the track assembly 4 to the unfolding mechanism 6.

[0032] Please Figures 1 to 3As shown, this technical solution addresses the complex scenario of arch frame transportation and deployment during tunnel construction by providing a mechanical structure collaborative control solution. Its core lies in the precise path control of the folded arch frame from its transportation state to its deployment state through the cooperation of the rotatable guide mechanism 3 and the track assembly 4, thereby improving transportation efficiency by replacing manual adjustments with mechanical structures. Secondly, the cooperation between the deployment mechanism 6 and the track assembly 4 enables the arch frame to transform its shape within a limited space. Thirdly, the coordinated action of the lifting mechanism, track assembly 4, guide mechanism 3, and deployment mechanism 6 allows the arch frame to move along the tunnel side, avoiding the space limitations of the integrated drilling and anchoring machine. The specific working principle is as follows: After the transport vehicle transports the folded arch frame to the designated position, the lifting device 2 is activated, lifting the folded arch frame. Simultaneously, the guide mechanism 3 rotates, switching to the first state of contact with the inner side of the folded arch frame. The lifting device grasps the folded arch frame and moves it along the track assembly 4 until it reaches the deployment mechanism 6. Upon reaching the deployment mechanism 6, the deployment mechanism 6 rotates, and the folded arch frame unfolds, completing the transformation of its working form. The guide mechanism 3, through its rotation and guidance, ensures that the folding arch frame will not interfere with the installed arch frame during transportation. The guide mechanism 3 has a first state of contact with the inner side of the folding arch frame, thus ensuring that the folding arch frame moves along the correct path. The track assembly 4 is designed to ensure the stability of the folding arch frame during movement and to ensure that the folding arch frame will not interfere with other structures when unfolded. Furthermore, the unfolding mechanism 6 only rotates and unfolds the folding arch frame after it reaches the designated position, ensuring that the folding arch frame can be safely unfolded to its working state and avoiding collisions with surrounding structures. Therefore, this technical solution, through the design of the guide mechanism 3 and track assembly 4, ensures that the folding arch frame makes reasonable use of space during transportation and unfolding, avoiding interference with other structures. The synergy of the guide mechanism 3, track assembly 4, lifting mechanism 5, and unfolding mechanism 6 ensures that the folding arch frame will not collide with the installed arch frame or other structures during movement and unfolding, improving operational safety.

[0033] Please Figure 4As shown, the guiding mechanism 3 includes: a base 31, which is fixedly mounted; a first rotating shaft 32, which is mounted on the base 31; a first support arm 33, which is connected to the base 31 and rotates via the first rotating shaft 32; and a guiding round end 34, which is located at the end of the support arm away from the first rotating shaft 32 and contacts the inner side of the folding arch frame. The main function of the guiding mechanism 3 is to ensure the stability of the contact with the folding arch frame. Specifically, the guiding mechanism 3 is improved in the following aspects: First, the guiding round end 34 is designed as an arc shape, which can match the shape of the inner side of the folding arch frame, ensuring that there will be no offset or interaction during the contact process; Second, the first support arm 33 rotates via the first rotating shaft 32, ensuring that the guiding round end 34 can accurately contact the inner side of the folding arch frame. By rotating the first support arm 33, the guiding round end 34 can maintain stable contact with the inner side of the folding arch frame. Third, the base 31 is fixedly installed to ensure the stability of the guiding mechanism 3 during operation. The fixed base 31 allows the guiding mechanism 3 to maintain a stable position and posture, ensuring stable contact between the guiding end 34 and the inner side of the folding arch frame. Fourth, the first rotating shaft 32, mounted on the base 31, supports and rotates the first support arm 33. This support ensures the stability and accuracy of the first support arm 33 during rotation, thereby ensuring stable contact between the guiding end 34 and the inner side of the folding arch frame. Therefore, through the above design, the guiding mechanism 3 can ensure stable contact with the inner side of the folding arch frame during transportation, improving the reliability and safety of the device.

[0034] Please Figure 9As shown, in the embodiment provided by this utility model, the unfolding mechanism 6 includes: a second rotating shaft 51, which is rotatably connected to the frame 1; a second support arm 52, which is rotatably connected to the second rotating shaft 51; and an unfolding circular end 53, which contacts the folding arch frame. In this embodiment, the main function of the unfolding mechanism 6 is to ensure stability during the unfolding process. Specifically, the second rotating shaft 51 is rotatably connected to the frame 1 and is used to support and rotate the second support arm 52. Through the support of the second rotating shaft 51, the stability and accuracy of the support arm during rotation are ensured, thereby ensuring stable contact between the unfolding circular end 53 and the folding arch frame. The rotation of the second support arm 52, which is rotatably connected to the second rotating shaft 51, allows the unfolding circular end 53 to contact the folding arch frame and unfold the arch frame. The rotation of the second support arm 52 ensures that the unfolding circular end 53 can accurately contact the folding arch frame, ensuring stability during the unfolding process. The unfolding end 53 is designed in an arc shape to match the shape of the folding arch frame. This arc design reduces friction and resistance during unfolding, improving stability. Furthermore, the frame 1 is fixed, and the second rotating shaft 51 is connected to the frame 1. The fixed frame 1 ensures the stability of the unfolding mechanism 6 during operation. By fixing the frame 1, the unfolding mechanism 6 can maintain a stable position and posture, ensuring stable contact between the unfolding end 53 and the folding arch frame. Therefore, through the above design, the unfolding mechanism 6 can ensure stable contact with the folding arch frame during unfolding, improving the reliability and safety of the device.

[0035] Please Figures 5 to 6As shown, the track assembly 4 further includes an upper track 41, which includes a first track body 411 fixedly connected to the frame 1; and a first guide shaft 412, which is alignable with the guide round end 34 and contacts the inner side of the folding arch frame. In this embodiment, the upper track 41 includes a first track body 411 fixedly connected to the frame 1. The upper track 41 guides the movement of the folding arch frame during transportation, ensuring that the folding arch frame can move stably along the upper track 41. The first guide shaft 412 contacts the inner side of the folding arch frame, ensuring the stability and accuracy of the folding arch frame during movement through the guidance of the first guide shaft 412. Therefore, the track assembly 4, through the cooperation of the upper track 41 and the first guide shaft 412, can ensure the stability and accuracy of the folding arch frame during transportation, reducing deviation and swaying during movement. The guidance of the track assembly 4 reduces the risk of the folding arch frame during transportation and improves operational safety. The design of track assembly 4 ensures that the folding arch frame can be moved quickly and stably to the designated position, improving transportation efficiency. In addition, the compact design of track assembly 4 occupies little space, enabling it to operate in confined spaces, thus improving the applicability of the entire device. Furthermore, the simple structure of track assembly 4 makes it easy to maintain and replace, reducing maintenance costs.

[0036] Please Figure 6 As shown, the track assembly 4 includes a lower track 42, which includes a second track body 421 fixedly connected to the frame 1; and a second guide shaft 422, which contacts the inner side of the folding arch frame and is parallel to the first guide shaft 412. In this embodiment, the lower track 42 includes the second track body 421, which is fixedly connected to the frame 1. The lower track 42 guides the folding arch frame during transportation, ensuring that the folding arch frame can move stably along the track. The second guide shaft 422 contacts the inner side of the folding arch frame and is parallel to the first guide shaft 412. The second guide shaft 412 can be aligned with the guide round end 34. The guidance of the second guide shaft 422 ensures the stability and accuracy of the folding arch frame during movement. In this embodiment, both the first track body 411 and the second track body 421 are fixedly connected to the frame 1, ensuring the stability and accuracy of the track assembly 4 during operation. Furthermore, both the first guide shaft 412 of the upper rail 41 and the second guide shaft 422 of the lower rail 42 are in contact with the inner side of the folding arch frame, and the two guide shafts remain parallel. This design ensures that the folding arch frame can be guided by both the upper rail 41 and the lower rail 42 simultaneously during movement, maintaining stability and accuracy. Thus, the folding arch frame slides along the upper rail 41 and the lower rail 42, with both working together to ensure that the folding arch frame can move quickly and stably to the designated position.

[0037] In the embodiment provided by this utility model, two sets of track assemblies 4 are symmetrically arranged on both sides of the frame 1. The two sets of track assemblies 4 simultaneously guide the folding arch frame. The first guide shaft 412 of the upper track 41 and the second guide shaft 422 of the lower track 42 work together at symmetrical positions on both sides to ensure that the folding arch frame does not shift or sway during movement, maintaining stability. Therefore, this symmetrical design ensures the smoothness and stability of the folding arch frame during transportation.

[0038] The second guide shaft 422 is aligned with the ends of the guide circular end 34 and the unfolded circular end 53. Located between the guide circular end 34 and the unfolded circular end 53, the second guide shaft 422 provides intermediate support and path calibration during the transport of the folding arch frame. When the axis of the second guide shaft 422 coincides with the center lines of the ends of the guide circular end 34 and the unfolded circular end 53, a continuous coaxial channel is formed, ensuring the continuity of the transport trajectory of the folding arch frame. This end alignment creates geometric constraints, allowing the diameters and curvatures of the guide circular end 34, the second guide shaft 422, and the unfolded circular end 53 to be designed to be consistent. Through a smooth transition of the contact surface, this prevents the folding arch frame from jamming or deviating during movement. Therefore, in this embodiment, the second guide shaft 422 serves as an intermediate support point to balance the long-span load of the folding arch frame, reducing vibration and trajectory deviation during sliding. Furthermore, the alignment of the three components forms a continuous guide channel (guide circular end 34—second guide shaft 422—unfolded circular end 53), avoiding the risk of collision with already installed arch frames. It can also solve the spatial constraints of long-distance transportation.

[0039] Furthermore, multi-axis dynamic alignment can be achieved through the linkage mechanism, and the positioning error from the end of the folding arch frame to the unfolding mechanism 6 is controlled within 2mm. It can be seen that the second guide shaft 422 can reduce the friction of the folding arch frame sliding and extend the service life of the overall device.

[0040] Furthermore, the outer contours of the guiding end 34 and the unfolding end 53 are adapted to the inner shape of the folding arch frame. The guiding end 34 is mainly responsible for contacting the inner side of the folding arch frame in the initial stage of transportation, guiding the folding arch frame into the predetermined transportation track through the matching of its outer contours; while the unfolding end 53 contacts the inner side of the folding arch frame at the end of transportation, driving the folding arch frame to unfold to its working state through shape adaptation. The outer contours of both are perfectly matched with the geometry (such as arc curvature and folding angle position) of the inner side of the folding arch frame, forming physical constraints. Therefore, by adapting the contours of the guiding end 34 and the unfolding end 53 to the inner side of the folding arch frame, the transportation and unfolding actions are transformed into a purely mechanical interaction, without the need for external power intervention. This contour adaptation design of the guiding end 34 and the unfolding end 53 enables this scheme to achieve high precision, high stability, and strong reliability in the transportation of the folding arch frame at the mechanical level, providing key technical support for the automation of tunnel construction.

[0041] Please Figure 7 As shown in the embodiment provided by this utility model, the lifting device 2 includes: a first lifting assembly 21 and a support platform 22. One end of the support platform 22 is connected to the first lifting assembly 21, and a sliding pair is provided between the first lifting assembly 21 and the support platform 22. The support platform 22 is used to lift the arch frame and move it onto the guide mechanism 3. The first lifting assembly 21 provides the core mechanism for vertical power output. The first lifting assembly 21 can be a hydraulic cylinder, a gear rack, or a lead screw structure to undertake the lifting function of the folding arch frame. The support platform 22 is a bearing platform that directly contacts the folding arch frame. One end is connected to the guide mechanism 3, and the other end is connected to the first lifting assembly 21 through the sliding pair. The sliding pair is a linear motion mechanism installed between the first lifting assembly 21 and the support platform 22, such as a combination of guide rail and slider, which allows the support platform 22 to move horizontally during the lifting process. This embodiment provides a transverse transport device for the arch frame. Through a sliding pair, the horizontal positioning error is controlled to a very small range, ensuring precise docking between the folded arch frame and the guide mechanism 3. It also enables a combined vertical lifting and horizontal transfer motion path, avoiding the limitations of narrow spaces on the tunnel sides and saving significant longitudinal space compared to traditional linear lifting. Furthermore, this solution uses sequential vertical lifting and horizontal transfer, rather than unidirectional movement, resulting in more precise positioning of the folded arch frame within a limited space. Therefore, the lifting device 2 in this embodiment, through innovative mechanical structure, achieves efficient and stable transport of the folded arch frame within a confined space.

[0042] This utility model also provides a trolley, which includes the arch frame transverse transport device in any of the above embodiments, and also has the advantages of the arch frame transverse transport device, which will not be described in detail here.
