DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] Based on the arched structure of the tunnel section, before installing the reinforced corrugated plate on the inner wall of the tunnel, the corrugated plate needs to be prefabricated in advance into a shape that matches the curvature of the tunnel section. Since the curvatures at different positions of the tunnel section are different, corrugated plates with different curvatures need to be processed accordingly. In the prior art, corrugated plates are usually processed by stamping. When processing different curvatures, the stamping die needs to be replaced many times. The equipment cost is high, the process is cumbersome, and a lot of time and human resources are wasted, which can easily delay the construction progress of the tunnel. In addition, a complex scaffolding structure needs to be built when installing the corrugated plate, which further slows down the construction progress, often resulting in a waste of skylight time and delaying the normal operation of the railway. To this end, the present invention provides an online shaping device and installation method for tunnel reinforcement corrugated plates. The shaping curvature is adjusted in real time according to the acquired tunnel section data through a telescopic adjustment component during the processing. Corrugated plates with different curvatures can be processed with only one device, which saves a lot of equipment, manpower and time costs and shortens the construction period. The feeding component cooperates with the shaping component to feed the material, and an arc-shaped corrugated plate support and guide component is arranged at the bottom of the corrugated plate for support. The processing and installation functions are integrated into one device, and the construction process is more compact and convenient for construction personnel to operate. In addition, the arc-shaped corrugated plate support and guide component can cooperate with the corrugated plate feeding and moving, without the need to build a scaffolding, which saves a lot of time in preparation work, further improves construction efficiency, and ensures the normal operation time of the railway.

The tunnel reinforcement corrugated plate online shaping equipment includes a bracket 40, a feeding assembly 70, a shaping assembly 30 and a curved corrugated plate 20 support guide assembly. The feeding assembly 70 is used to drive the corrugated plate 20 to feed into the shaping assembly 30, and the corrugated plate 20 is processed into an arc matching the tunnel section through the shaping guide wheel 31 in the shaping assembly 30. The shaping assembly 30 is provided with a telescopic adjustment assembly 32 for driving the shaping guide wheel 31 to change the shaping curvature. Specifically, the bracket 40 is provided with a feeding end and a discharging end suitable for the corrugated plate 20 to pass through.

The arc-shaped corrugated plate 20 support and guide assembly includes a first telescopic support rod 11 and a second telescopic support rod 12 for supporting the shaped corrugated plate 20, and a slide rail arranged along the feeding direction of the corrugated plate 20, wherein the first telescopic support rod 11 and the second telescopic support rod 12 are respectively slidably assembled with the slide rail. Among them, the profiles of the surfaces of the feed roller 71 and the shaping guide wheel 31 are adapted to the waveform of the corrugated plate 20 .

[0026] In the embodiment of the present application, the shaping guide wheel 31 is driven to change its position and adjust the shaping curvature through the telescopic adjustment component 32, and the corrugated plates 20 with different curvatures can be processed by only one device, which saves a lot of equipment and labor costs and significantly improves the processing efficiency. The corrugated plate 20 can be directly output from the shaping component 30 to the top wall of the tunnel, connecting the shaping and installation processes together. During the output process, the arc-shaped corrugated plate 20 support guide component can move with the corrugated plate 20, and there is no need to install a complex scaffolding structure at the bottom of the corrugated plate 20, which further speeds up the construction progress, avoids the construction period being too long and exceeding the skylight time, and ensures that the construction does not occupy the normal operation time of the railway.

[0027] In an alternative embodiment, see Figure 2 and Figure 4 The telescopic adjustment component 32 is a first hydraulic rod. One end of the first hydraulic rod is assembled on the bracket 40, and the other end is assembled with the axle of the shaping guide wheel 31. The telescopic amount of each first hydraulic rod is adjusted based on the curvature of the top of the tunnel to be reinforced.

[0028] In an optional embodiment, a positioning member 111 suitable for limiting the front end of the corrugated plate 20 is provided at the top of the first telescopic support rod 11.

The upper pressing piece 51 is assembled on the bracket 40 through a second hydraulic rod. When two corrugated plates 20 need to be connected, the upper pressing piece 51 presses down to press the screws on the hinge used to connect the two sections of the corrugated plates 20 onto the corrugated plates 20. A receiving groove 54 is provided on the upper pressing piece 51, and the receiving groove 54 includes a first groove body suitable for accommodating the hinge and a second groove body suitable for accommodating the top of the screw. In this embodiment, based on the characteristics of the plastic material of the corrugated plate 20, the screws are fixed to the corrugated plate 20 by cold pressing, threaded holes are prefabricated on the corrugated plate 20, and the screws are pressed into the threaded holes by the upper pressing piece 51, thereby completing the fixing of the screws.

The pressing rod 531 is suitable for pressing the front end of the pressing block 533 and driving the limiting member 532 to flip toward the direction close to the upper pressing member 51. The upper pressing member 51 is provided with a limiting groove 534 suitable for buckling with the top of the limiting member 532. When the lower pressing member 52 is pressed down, the pressing rod 531 is pressed down accordingly and triggers the pressing block 533 to flip forward. At the same time, the pressing block 533 drives the limiting member 532 to flip toward the upper pressing member 51, so that the top of the limiting member 532 is buckled into the limiting groove 534 of the upper pressing member 51. When the upper pressing member 51 is lifted, the pressing rod 531 releases the pressing block 533 , thereby releasing the restriction on the limiting member 532 . The limiting member 532 flips backward under the action of its center of gravity, and its top part escapes from the limiting groove 534 .
