Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of mining engineering and tunnel excavation equipment, and specifically relates to a large-angle machine-mounted temporary support. Background Technology
[0002] During tunnel excavation, after the tunneling equipment completes the excavation, anchor mesh support technology is required to permanently support the tunnel and ensure subsequent safe production. The telescopic cylinders inside the left and right telescopic arms of the machine-mounted temporary support can be controlled separately to achieve left and right tilting of the temporary support roof. However, this solution has limited tilting angles and is mainly suitable for slight tilting of the tunnel roof caused by construction errors (generally below 8°). When the tunnel roof already has a large tilt angle (such as 15°), the existing solution cannot meet the requirements.
[0003] Therefore, there is an urgent need for a new solution with a wider range of tilt angle adjustment to address the aforementioned shortcomings of existing technologies. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a large-angle, machine-mounted temporary support system, which has a large inclination angle and is suitable for trapezoidal roadways with a large inclination angle on the roof.
[0005] The technical solution provided by this invention is as follows:
[0006] This invention provides a large-angle onboard temporary support, including a top frame assembly. The top frame assembly includes a fixed frame, an angle adjustment component, and a moving frame with hinged lateral flaps on the left and right sides and a forward extension component on the front side. The left and right sides of the fixed frame are respectively hinged to the top of telescopic adjustment components symmetrically arranged on both sides of the cutting mechanism of the tunneling machine. The bottom of the telescopic adjustment components on both sides is connected to the drive end of a tilting cylinder fixed on the same side of the cutting mechanism. The moving frame and the fixed frame are provided with mounting seat group one and mounting seat group two on the front and rear sides, which make the moving frame tilt to the left or right. According to the inclination direction of the roadway, the moving frame is hinged to the left or right side of the fixed frame, and the angle adjustment component is correspondingly connected to mounting seat group one or mounting seat group two. The moving frame achieves superimposed adjustment of the lateral inclination angle through the independent extension and retraction of the telescopic adjustment components on both sides and the adjustment of the angle adjustment component.

[0011] Furthermore, the lateral flap is arranged in a right-angled trapezoidal shape and includes a first horizontal plate, a vertical plate, a first horizontal plate, and an inclined plate connected in sequence. The length of the first horizontal plate is less than that of the second horizontal plate and is equal in length to the third connecting plate on the side closer to the third connecting plate. The third connecting plate is provided with a second hinge lug. The first horizontal plate is provided with a second hinge lug corresponding to the second hinge lug. Several vertical plates are also provided between the first horizontal plate and the second horizontal plate.
[0012] Furthermore, the forward extension includes a first forward sliding rail, a second forward sliding rail, and a forward extension horizontal tube. The second left fixed tube and the second right fixed tube are respectively provided with a first forward sliding track and a second forward sliding track that slide in cooperation with the first forward sliding rail and the second forward sliding rail.

[0016] Beneficial effects
[0017] This invention utilizes a selectable left-right hinged connection between the moving frame and the fixed frame, along with corresponding angle adjustment components, enabling the roof frame assembly to be rapidly reconfigured according to the actual inclination direction of the roadway. During actual operation, the independent telescopic movement of the two side telescopic adjustment components allows for initial lateral inclination adjustment of the roof frame assembly. Based on this, a secondary fine adjustment is performed using the angle adjustment components, thus achieving a superimposed adjustment function for the lateral inclination angle. This dual adjustment mechanism not only significantly improves the fit between the support roof frame and the inclined roadway roof, ensuring support stability under large inclination conditions, but also greatly enhances the equipment's adaptability to different roadway geological conditions. Simultaneously, the design of the left-right hinged lateral flaps further expands the effective support area, effectively preventing the risk of roof spalling and providing reliable protection for the safety of the tunneling face.
[0018] During assembly and practical application, this invention achieves adjustable and adaptable support structure tilt angles through precise hydraulic system control. Specifically, operators can independently control the extension length of the left and right telescopic adjustment components via the hydraulic system, while simultaneously adjusting the extension amount of the angle adjustment components, thereby realizing the cumulative adjustment function of the moving frame tilt angle. This cumulative adjustment mechanism can superimpose the basic tilt angle and the secondary adjustment tilt angle, allowing the overall lateral tilt angle of the moving frame to reach a wider range, effectively adapting to roadway conditions with larger tilt angles. Furthermore, when the roadway tilt direction changes, simply changing the hinge position between the moving frame and the fixed frame during assembly or disassembly maintenance, and connecting the angle adjustment components to the corresponding mounting bases, allows for flexible switching of the left and right tilt directions of the moving frame. This design enables the same support device to flexibly adapt to the needs of roadways with different left and right tilt directions without replacing core components, greatly improving the equipment's versatility and on-site adaptability, and reducing equipment procurement and maintenance costs.

[0030] like Figure 1As shown, this embodiment of the invention provides a large-angle onboard temporary support, including a top frame assembly. The top frame assembly includes a fixed frame 6-1, an angle adjustment component, and a moving frame 6-2 with a forward extension component on the front side and hinged lateral flaps 6-3 on the left and right sides. The left and right sides of the fixed frame 6-1 are respectively hinged to the top of the telescopic adjustment components symmetrically arranged on both sides of the cutting mechanism 1 of the tunneling machine. The bottom of the telescopic adjustment components on both sides is connected to the drive end of the tilting cylinder 3 fixed on the same side of the cutting mechanism 1. The moving frame 6-2 and the fixed frame 6-1 are provided with mounting seat group one 8-1 and mounting seat group two 8-2 on the front and rear sides, which make the moving frame 6-2 tilt to the left or right. According to the inclination direction of the roadway, the moving frame 6-2 is hinged to the left or right side of the fixed frame 6-1, and the angle adjustment component is correspondingly connected to the mounting seat group one 8-1 or the mounting seat group two 8-2.
