Abstract
Description
Technical Field
[0001] The utility model relates to the field of lining trolleys, in particular to a multi-section large-diameter variable-diameter tunnel lining trolley. Background Art
[0002] Lining refers to a permanent support structure built with reinforced concrete and other materials along the perimeter of the tunnel to prevent deformation or collapse of the surrounding rock. Lining technology is usually used in tunnel engineering and water conservancy channels. Lining is simply the inner lining, and the most common lining is block lining, which can be prestressed high-pressure grouting plain concrete lining.
[0003] However, the size of the trolley used for tunnel lining is usually fixed, and different sizes of lining arc plates are required for tunnels of different diameters, which makes it impossible to achieve "one trolley for multiple uses". Therefore, those skilled in the art provide a multi-section large-diameter variable-diameter tunnel lining trolley to solve the problems raised in the above background technology.

[0005] The support rod is installed with a first mounting frame, the first mounting frame is installed with a first arc plate, the top of the beam is fixedly connected with a door frame, the top of the door frame is installed with a second mounting frame, the second mounting frame is installed with a second arc plate, the top of the beam is fixedly connected with a fixed block, the fixed block is installed with a third mounting frame, and the third mounting frame is installed with a third arc plate.
[0006] Preferably: a lifting device is installed between the moving vehicle and the support rod.
[0007] Preferably: the disassembly beam and the fixed beam are both fixed by bolts and nuts.
[0008] Preferably: the portal frame is equipped with a first jack.
[0009] Preferably: the first mounting frame, the second mounting frame and the third mounting frame are all provided with a rotating device, and the rotating device is fixedly connected to a second jack.
[0010] Preferably: the rotating part of the rotating device is fixedly connected to a fixing frame, and the fixing frame is fixedly connected to the corresponding arc plate.
[0011] Technical effects and advantages of the utility model:
[0012] When dealing with tunnels of different diameters, the third arc plate can be added or reduced and combined with the original arc plate to form a new total arc plate, making the total arc plate diameter larger or smaller. This allows the tunnel lining trolley to be used for multiple purposes and is suitable for the construction of tunnels of various diameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.
[0021] See also Figures 1-2 In this embodiment, a multi-section large-diameter variable-diameter tunnel lining trolley is provided, including a support rod 8, a moving vehicle 1 is installed at the bottom of the support rod 8, a lifting device 2 is installed between the moving vehicle 1 and the support rod 8, and a cross beam 9 is provided on the top of the support rod 8. The cross beam 9 includes a disassembly beam 91 and a fixed beam 92, and the disassembly beam 91 and the fixed beam 92 are fixed by bolts and nuts;
[0022] The support rod 8 is installed with a first mounting frame 3, the first mounting frame 3 is installed with a first arc plate 4, the top of the crossbeam 9 is fixedly connected with a door frame 11, the top of the door frame 11 is installed with a second mounting frame 6, the second mounting frame 6 is installed with a second arc plate 5, the top of the crossbeam 9 is fixedly connected with a fixing block 13, the fixing block 13 is installed with a third mounting frame 12, and the third mounting frame 12 is installed with a third arc plate 7;
[0023] The gantry 11 is installed with a first jack 14, and the first mounting frame 3, the second mounting frame 6 and the third mounting frame 12 are all provided with a rotating device 32, the rotating device 32 is fixedly connected with the second jack 33, the rotating part of the rotating device 32 is fixedly connected with the fixing frame 31, and the fixing frame 31 is fixedly connected with the corresponding arc plate.
[0024] The working principle of the utility model is:
[0025] The portal frame 11, the beam 9, the support rod 8 and the mobile vehicle 1 together constitute a tunnel masonry trolley. The first jack 14 can drive the mounting frame and the arc plate to retract or extend together. The rotating device 32 can drive the mounting frame and the arc plate to rotate. When the tunnel diameter is changed and becomes larger, the screw and nut at the connection of the disassembly beam 91 or the fixed beam 92 on the current beam 9 are removed, and the disassembly beam is further increased, and then fixed with the screw and nut. If necessary, the portal frame 11 and the beam 9 are disassembled and re-fixed, and finally the width of the beam 9 is increased. After the width is increased, the reinforcement is installed appropriately. The rod body is used to prevent the middle supporting capacity from being reduced due to the increase in the length of the cross beam 9. The fixing block 13 and the third mounting frame 12 are further installed. The third arc plate 7 is set in the gap between the first arc plate 4 and the second arc plate 5. The first jack 14 and the rotating device 32 are used to extend and rotate respectively, so as to adjust the position of the arc plate, so that the first arc plate 4, the second arc plate 5 and the third arc plate 7 together form a new total arc plate, so that the total arc plate diameter becomes larger, thereby making the tunnel lining trolley multi-purpose and suitable for tunnel construction of various diameters;
[0026] When the tunnel becomes smaller, part of the disassembly beams and a number of third arc plates and the third mounting frame 12 are disassembled.
