Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction, specifically relating to an installation 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, it may lead to uncontrolled release of surrounding rock pressure after support is installed, causing 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 surrounding rock displacement. However, the integrated drilling and anchoring machine has highly integrated and multifunctional characteristics, with relatively compact modules and limited operating space, so it cannot simultaneously perform functions such as grabbing, translation, and lifting. Utility Model Content

[0011] Preferably, the slewing assembly includes: a slewing support, which is rotatably connected to the bottom of the first telescopic rod, and the slewing support is fixedly connected to the base plate.

[0012] Preferably, when the pulley is located at the bottom of the base plate, there are at least two pulleys, which are evenly distributed at the bottom of the base plate.

[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 7As shown, this utility model provides an installation device, including: a lifting device 1, which lifts the arch frame to a preset height; a jacking device 2, which is located on one side of the lifting device 1 and includes: a jacking frame 21 for gripping the arch frame; a support arm 22, one end of which is connected to the bottom of the jacking frame 21, and the support arm 22 has an extended state or a retracted state; a rotating assembly 23, which is rotatably connected to the other end of the support arm 22; and a first sliding assembly 4, which is located at the bottom of the rotating assembly 23. In the embodiments provided in this application, the lifting device 1 first raises the arch frame to a preset height, and the jacking device 2 moves the entire jacking frame 21 to the bottom of the lifting device 1. At this time, the support arm 22 switches to the extended state and grabs the arch frame onto the jacking frame 21. The support arm 22 then switches to the retracted state, and the rotary component 23 rotates towards the working face. The first sliding component 4 slides the entire arch frame to a preset position on the working face. After reaching the installation position, the telescopic arm extends to a high position to install the arch frame. After installation, the telescopic arm retracts to a low position, and the first sliding component 4 retracts back to the opposite direction on the working face to start the next cycle. In this embodiment, a composite structure of the telescopic arm and the rotary component 23 is used to realize the rotation function, and the first sliding component 4 realizes the movement function. In this way, through phased motion control, the grabbing-rotation-translation-jacking-resetting is completed, which solves the inefficiency problem of traditional manual adjustment. On the other hand, the separate design of rotation and translation functions means that only the telescopic arm moves during rotation, while the arch frame and lifting frame 21 remain stable, solving the problem of easy swaying of the rotating arch frame during traditional arch frame installation. Therefore, the installation device provided by this application can simultaneously complete gripping, translation, and lifting in confined spaces.

[0030] The first sliding assembly 4 includes a base plate 241 mounted on the frame of the trolley; and a pulley 242 located on the side or bottom of the base plate 241, forming a sliding pair with the guide rails on the frame. The base plate 241 is fixed to the frame of the trolley, serving as the basic structure of the sliding assembly. The pulley 242, mounted on the side or bottom of the base plate 241, forms a sliding pair with the guide rails on the trolley frame. This sliding pair structure allows the base plate 241 to slide freely on the guide rails, achieving a translation function. The sliding pair structure between the pulley 242 and the guide rails ensures stability during translation, reduces friction and wear, and improves the stability and service life of the installation device. Furthermore, by precisely controlling the sliding of the pulley 242, the lifting device 2 can be accurately translated, ensuring that the arch frame can be installed in the designated position. The design of the first sliding assembly 4 allows the lifting device 2 to translate at different positions, demonstrating strong adaptability and meeting various installation requirements.

[0031] In the embodiments provided by this utility model, the installation device includes a second sliding component 25, which is disposed between the lifting frame 21 and the support arm 22. The second sliding component 25 includes: a first slide rail 251, the bottom of which is connected to the support arm 22; and a first slider 252, which is disposed at the bottom of the lifting frame 21, forming a sliding pair with the first slide rail 251. This application mainly integrates four functions—grabbing, rotating, translating, and lifting—in a confined space through a nested structure of the telescopic arm, the rotating component 23, and the first sliding component 4. Compared with the traditional split structure, it saves a significant amount of installation space. First, the layered rotating design of the support arm 22 and the rotating component 23 ensures that only the telescopic arm moves during rotation, while the arch remains stationary, eliminating the problem of inertial offset in traditional overall rotation. Second, the dual sliding components work together, forming an orthogonal motion plane through the first sliding component 4 (bottom) and the second sliding component 25 (top). Horizontal translation and vertical telescopic movement do not interfere with each other, resulting in a significant improvement in motion accuracy.

[0032] The support arm 22 includes: a first telescopic rod 221, one end of which is connected to the base plate 241, and the other end of which is connected to the first slide rail 251; and a first drive assembly 222, one end of which is fixedly connected to the telescopic end of the first telescopic rod 221, driving the first telescopic rod 221 to switch between an extended state and a retracted state. More preferably, a three-stage nested sleeve can be used, shortening the retracted length while significantly increasing the extended length. The retracted volume is reduced compared to a traditional single-machine telescopic arm, adapting to the compact layout of the drilling and anchoring machine, while increasing rigidity; for example, the sleeve can use a conical fit to improve bending strength. Furthermore, the first drive assembly 222 is directly fixed to the telescopic end, simplifying the structure and improving response time. Therefore, in this embodiment, through the three-stage sleeve direct drive structure and the rigid connection design of the first sliding assembly 4 and the second sliding assembly 25, a reduced volume, increased load-bearing capacity, and improved maintenance efficiency are achieved under the same functional conditions, perfectly solving the rigid requirements of heavy-duty, high-frequency telescopic operations in a confined space for the drilling and anchoring machine.

[0033] The slewing assembly 23 includes a slewing support 231, which is rotatably connected to the bottom of the first telescopic rod 221 and fixedly connected to the base plate 241. The slewing support 231 can be designed with an upper flange and a lower flange. The upper flange is rotatably connected to the bottom of the first telescopic rod 221, while the lower flange is rigidly fixed to the base plate 241. This way, the slewing motion only acts on the first telescopic rod 221, while the base plate 241 remains stationary, eliminating the vibration transmission problem of traditional integral slewing. Simultaneously, the center of rotation is lowered to the plane of the base plate 241, significantly improving the anti-overturning capability. Therefore, through this split-type slewing support 231 and high-rigidity flange connection design, a significant improvement in anti-overturning capability is achieved under the same functional requirements, while reducing space occupation and improving positioning accuracy, thus solving the heavy-load, high-frequency slewing operation requirements of the drilling and anchoring integrated machine.

[0034] In the embodiments provided in this application, when the pulleys 242 are located at the bottom of the base plate 241, at least two pulleys 242 are provided and are evenly distributed at the bottom of the base plate 241. This symmetrical arrangement of the double pulleys 242 forms a statically determinate support system, and at the same time, this symmetrical arrangement can also generate a reverse torque, further improving the anti-overturning capability.

[0035] Alternatively, when the pulleys 242 are located on the side of the base plate 241, the number of pulleys 242 is even, and they are symmetrically arranged on the side of the base plate 241. This even-numbered symmetrical layout, such as four sets of pulleys 242, two sets on each side, forms a two-way constraint structure, significantly improving lateral stiffness and providing more balanced force distribution. Side mounting of the pulleys 242 frees up space below the base plate 241, providing height space for facilitating the arrangement of pipelines or other transmission mechanisms. It also ensures that the pulleys 242 on both sides of the base plate 241 can be driven independently, allowing for real-time compensation for track deviations and preventing deviation of the movement path.

[0036] In the embodiments provided by this utility model, there are two first sliders 252, which are symmetrically arranged. The cross-section of the first slider 252 is formed into an arc shape. The first slide rail 251 is provided with a first groove, which cooperates with the first slider 252. The two first sliders 252 are spaced apart to form a statically determinate support system, which can improve the service life of the first sliders 252 and the first slide rail 251. By setting the first slider 252 as an arc-shaped slider, a bidirectional constraint is formed with the first groove, which improves the lateral stiffness, enhances the resistance to eccentric load, and reduces frictional resistance. Therefore, through this structure of symmetrical double sliders and arc-shaped guide surface, the technical effects of doubling the load-bearing capacity, improving the lateral stiffness, and improving the positioning accuracy are achieved in the same space, solving the problem of eccentric load and wear in heavy-load, high-precision sliding scenarios of the drilling and anchoring machine.

[0037] Preferably, the installation device includes a lifting device 1, which 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 lifting frame 21 of the lifting device 2. 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 lifting frame 21 of the lifting device 2. The support arm 22 of the lifting device 2 then extends to grab and transport the arch frame.
