Description

Technical Field

[0001] This invention relates to the field of tunnel excavation machinery technology, and in particular to an advanced support platform. Background Technology

[0002] Currently, in my country's tunnel excavation construction, face-to-face excavation is not permitted under an open roof. Therefore, all tunnel excavation equipment must operate under supported tunnels. Existing technologies generally employ pre-support methods, first temporarily supporting the tunnel roof, then drilling anchor bolt or cable holes using an anchor bolt machine, and finally securing the anchor mesh to the tunnel roof and side walls with anchor bolts or cables. Cement grout is then sprayed onto the anchor mesh to form permanent support.

[0003] Most existing advanced support platforms are cantilever structures. These cantilever support platforms have a simple structure and a fixed support height, making them unsuitable for varying roadway heights. Therefore, providing a support platform that can adapt to changes in roadway height is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The purpose of this invention is to provide an advanced support platform that can adapt to changes in the cross-sectional size of the roadway and working conditions through its own deformation.

[0040] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1-14 As shown, this embodiment provides an advanced support platform 100, including a support frame assembly 1, a support base assembly 2, and a support structure 3.

[0042] The support frame assembly 1 includes a top frame 11, a connecting frame 12, a support cylinder 13, a front support cylinder 14, and a front protective net 15. The top frame 11 supports the top of the tunnel. The connecting frame 12 is hinged to the top frame 11, and the first end of the support cylinder 13 is hinged to the connecting frame 12. The rotation axes at both hinge points are horizontal and perpendicular to each other, ensuring the support cylinder 13 remains vertical when suspended. The support cylinder 13 can extend and retract to allow its second end to rest against the bottom of the tunnel. The first end of the front support cylinder 14 is hinged to the connecting frame 12, and the second end of the front support cylinder 14 is hinged to the cylinder body of the support cylinder 13, allowing the angle of the support cylinder 13 to be changed. The front protective net 15 is installed on the cylinder body of the support cylinder 13 and supports the tunnel face when the second end of the support cylinder 13 rests against the bottom of the tunnel. The support seat assembly 2 is connected to the top frame 11 to support the top frame 11. The front part of the support structure 3 is connected to the support seat assembly 2, and the rear part of the support structure 3 is used to connect the main frame 4 of the roadway construction machinery; the support structure 3 can adjust the height and front and rear tilt angle of the support seat assembly 2 so that the top frame 11 fits the top of the roadway.

[0043] In use, the front support cylinder 14 is gradually extended, thereby gradually adjusting the support cylinder 13 to a vertical position. Then, the positions of the top frame 11 and the support cylinder 13 are adjusted through the support structure 3, so that the top frame 11 fits against the top of the roadway, and the support cylinder 13 moves to the vicinity of the roadway face, with the front protective net 15 contacting the roadway face. Afterwards, the length of the support cylinder 13 is adjusted according to the roadway height, so that the second end of the support cylinder 13 rests against the bottom of the roadway. Because the length of the support cylinder 13 is adjustable, it can be adjusted according to the actual height of the roadway, ensuring that the top frame 11 always fits against the top of the roadway, thus providing strong adaptability.

[0044] To allow for adjustment of the top frame 11 according to the width of the tunnel, thus meeting the support requirements of tunnels with different widths, the top frame 11 in this embodiment includes a main frame 111, a secondary frame 112, and a frame telescopic cylinder 113. The main frame 111 is mounted on the support base assembly 2, and the secondary frame 112 is embedded within the main frame 111 and can slide relative to the main frame 111 in the left-right direction. The first end of the frame telescopic cylinder 113 is hinged to the main frame 111, and the second end of the frame telescopic cylinder 113 is hinged to the secondary frame 112 to adjust the left-right position of the secondary frame 112. When the frame telescopic cylinder 113 extends, the portion of the secondary frame 112 embedded within the main frame 111 shortens, increasing the overall width of the top frame 11; when the frame telescopic cylinder 113 shortens, the portion of the secondary frame 112 embedded within the main frame 111 lengthens, decreasing the overall width of the top frame 11.

[0045] In order to adjust the tilt angle of the top frame 11 in the left and right directions according to the inclination of the tunnel top, the support assembly 2 in this embodiment includes a spiral swing cylinder 21 and a first connecting component 22 and a second connecting component 23 connected to the spiral swing cylinder 21. The first connecting component 22 is connected to the top frame 11, and the second connecting component 23 is connected to the support structure 3. The swing axis of the spiral swing cylinder 21 is in the front-to-back direction. When the spiral swing cylinder 21 swings, it can change the relative position of the first connecting component 22 and the second connecting component 23, thereby changing the left and right tilt angle of the top frame 11.

[0046] To further increase the support area for the tunnel roof, this embodiment uses a left top frame and a right top frame to support the tunnel roof. Specifically, the first connecting assembly 22 includes a support base 221, a left support telescopic cylinder 222, a right support telescopic cylinder 223, a left support seat 224, and a right support seat 225. The lower part of the support base 221 is connected to the helical swing cylinder 21. The cylinder bodies of the left support telescopic cylinder 222 and the right support telescopic cylinder 223 are both placed on the support base 221, specifically in the corresponding strip-shaped grooves on the support base 221. The first end of the left support telescopic cylinder 222 is hinged to the support base 221, and the second end of the left support telescopic cylinder 222 is hinged to the left support seat 224. The first end of the right support telescopic cylinder 223 is hinged to the support base 221, and the second end of the right support telescopic cylinder 223 is hinged to the right support seat 225. The top frame 11 is divided into a left top frame and a right top frame. The left top frame is installed on the left support seat 224, and the right top frame is installed on the right support seat 225. Each of the left and right top frames is hinged to a connecting frame 12. When the left support telescopic cylinder 222 extends, the left support seat 224 moves to the left, simultaneously moving the left top frame to the left. When the left support telescopic cylinder 222 retracts, the left support seat 224 moves to the right, simultaneously moving the left top frame to the right. The operation of the right support telescopic cylinder 223 is similar and will not be described further here. When a top frame 11 moves, it will cause the connecting frame 12, support cylinder 13, front support cylinder 14, and front guard net 15 on the same side to move together.

[0047] To facilitate adjustment of the fore-and-aft position of the support frame assembly 1, this embodiment also includes a frame extension cylinder 5, which comprises a left frame extension cylinder and a right frame extension cylinder. A left guide rail 2241 is mounted on the left support seat 224, and a right guide rail 2251 is mounted on the right support seat 225. Both the left and right guide rails 2241 and 2251 are arranged along the fore-and-aft direction. The left top frame is slidably mounted on the left guide rail 2241, and the right top frame is slidably mounted on the right guide rail 2251. The first end of the left frame extension cylinder is hinged to the left support seat 224, and the second end of the left frame extension cylinder is hinged to the left top frame to adjust the fore-and-aft position of the left top frame. The first end of the right frame extension cylinder is hinged to the right support seat 225, and the second end of the right frame extension cylinder is hinged to the right top frame to adjust the fore-and-aft position of the right top frame. When the support frame assembly 1 needs to be moved forward, simply extend the left and right frame forward extension cylinders; when the support frame assembly 1 needs to be retracted backward, simply shorten the left and right frame forward extension cylinders.

[0048] In this embodiment, the left top frame includes a left main frame, a left sub-frame, and a left frame telescopic cylinder. The left main frame is slidably mounted on the left guide rail 2241, and the left sub-frame is embedded in the left main frame and can slide relative to the left main frame in the left-right direction. The first end of the left frame telescopic cylinder is hinged to the left main frame, and the second end of the left frame telescopic cylinder is hinged to the left sub-frame to adjust the left-right position of the left sub-frame. The right top frame includes a right main frame, a right sub-frame, and a right frame telescopic cylinder. The right main frame is slidably mounted on the right guide rail 2251, and the right sub-frame is embedded in the right main frame and can slide relative to the right main frame in the left-right direction. The first end of the right frame telescopic cylinder is hinged to the right main frame, and the second end of the right frame telescopic cylinder is hinged to the right sub-frame to adjust the left-right position of the right sub-frame.

[0049] There are various types of support structures 3, and those skilled in the art can choose according to actual needs. In this embodiment, the support structure 3 includes a support arm assembly 31, a support arm cylinder 32, and a translational cylinder 33. The first end of the support arm assembly 31 is hinged to the support base assembly 2, and the second end of the support structure 3 is hinged to the main frame 4. The first end of the support arm cylinder 32 is hinged to the support arm assembly 31, and the second end of the support arm cylinder 32 is hinged to the main frame 4 to change the angle of the support arm assembly 31. The first end of the translational cylinder 33 is hinged to the second connecting component 23, and the second end of the translational cylinder 33 is hinged to the support arm assembly 31 to change the angle of the second connecting component 23. By controlling the corresponding relationship between the extension and retraction distances of the support arm cylinder 32 and the translational cylinder 33, the top frame 11 can always be kept horizontal during the swinging process of the support arm assembly 31.

[0050] In this embodiment, the support arm assembly 31 is preferably a telescopic support arm assembly, the first end of which is hinged to the support base assembly 2, and the second end of which is hinged to the main frame 4.

[0051] Specifically, the outrigger assembly 31 includes an inner outrigger sleeve assembly 311, a pressure plate assembly 312, an outrigger telescopic cylinder 313, and an outer outrigger assembly 314. The first end of the outrigger telescopic cylinder 313 is hinged to the inner outrigger sleeve assembly 311, and the second end of the outrigger telescopic cylinder 313 is hinged to the outer outrigger assembly 314. The second ends of the second connecting assembly 23 and the translation cylinder 33 are both hinged to the inner outrigger sleeve assembly 311. The second end of the outrigger cylinder 32 and the main frame 4 are both hinged to the outer outrigger assembly 314. The pressure plate assembly 312 is installed on the outside of the outer outrigger assembly 314. When the outrigger telescopic cylinder 313 retracts, the pressure plate assembly 312 can move with the outer outrigger assembly 314 to the inside of the inner outrigger sleeve assembly 311. The size of the pressure plate assembly 312 can be adjusted to change the gap between the outer outrigger assembly 314 and the inner outrigger sleeve assembly 311.

[0052] Typically, the advanced support platform 100 needs to be installed together with the gantry assembly on the main frame 4 of the hydraulic anchor drilling rig. The gantry assembly has a left and a right outrigger for support. To facilitate passing within the roadway, the left and right outriggers of the gantry assembly are preferably foldable and stowed during passing, offset in height from the advanced support platform 100, so as not to occupy the passing height space.

[0053] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
