Problems solved by technology

When there are many tunnels in the curved section, and the tunnel is widened from 0 to 50cm, the clear width difference of the lining section is 40cm, and the clear height difference is up to 18cm. In this case, if the conventional lining trolley is still designed, It will cause an increase in the number of lining trolleys, and it will take a long time to reassemble the trolleys in the tunnel at the same time, which will affect the excavation progress of the tunnel face, resulting in the inability to carry out lining construction for about one month, causing the construction process steps to exceed the standard, resulting in The excavation of the face is stagnant, and the cost of tunnel construction is increasing

Embodiment 1

[0031] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the main frame 1 of the trolley, and the vertical frame 3 and the beam 2 are arranged on the upper end of the main frame 1 of the trolley. figure 2 It is a structural schematic diagram of the section widening value W=50+5cm, combined with figure 2 As shown, the integral self-propelled hydraulic lining trolley of the present invention includes an integral formwork, a trolley main frame 1 supporting the integral formwork, a vertical framework 3 supporting the integral formwork and a beam 2, arched at the left and right sides of the integral formwork The first hinge 13 and the second hinge 11 are arranged respectively at the position of 19-20 degrees; Figure 4 , the mark 18 is the radian of the position of the second hinge 13 .

[0032] Also, combine Figure 4 , the lining trolley of the present invention also includes a vertical adjustment block 19 for adjusting the height of the vertical f...

Embodiment 2

[0042] as attached image 3 Shown is the structural representation of the present invention at section widening value W=30+5cm, and the attached figure 2 The difference is that hydraulic system one 5 and hydraulic system two 4 are used to adjust the trolley to the design elevation and width of the changed section, and the hydraulic cylinder 16 and mechanical screw 17 are used to adjust the distance between the overall formwork and the main frame of the trolley. distance, and replaced the horizontal adjustment block and vertical adjustment block suitable for the changed section, and made full use of the directional rotation function of the hinge to adjust the overall formwork angle of the lining trolley, so that the outer contour radian of the lining trolley formwork is consistent with the designed lining The clear section is consistent, and the trolley is positioned and reinforced after meeting the design size.

Embodiment 3

[0044] as attached Figure 4 Shown is the structural representation of the present invention at section widening value W=10+5cm, and attached figure 2 And attached image 3 The difference is that hydraulic system one 5 and hydraulic system two 4 are used to adjust the trolley to the design elevation and width of the changed section, and the hydraulic cylinder 16 and mechanical screw 17 are used to adjust the distance between the overall formwork and the main frame of the trolley. distance, and replaced the horizontal adjustment block and vertical adjustment block suitable for the changed section, and made full use of the directional rotation function of the hinge to adjust the overall formwork angle of the lining trolley, so that the outer contour radian of the lining trolley formwork is consistent with the designed lining The clear section is consistent, and the trolley is positioned and reinforced after meeting the design size. Figure 4 The angle of the middle mark 18 is...

Abstract

The invention relates to the field of single track railway tunnel construction, in particular to an overall self-propelled hydraulic lining trolley. The overall self-propelled hydraulic lining trolley comprises an overall formwork, a trolley main framework supporting the overall formwork, a vertical framework supporting the overall formwork, and a beam, wherein the vertical framework and the beam are arranged at the upper end of the trolley main framework, and a first hinge and a second hinge are in the 19-20 degree positions of haunches on the left side and the right side of the overall formwork respectively. The lining trolley is good in integrality, easy to operate, high in adaptability and capable of meeting the requirement of construction of a plurality of clearance fracture surfaces of a single track railway, and one lining trolley can be applicable to a plurality of lining fracture surfaces.

Description

Technical field [0001] The present invention involves the field of single -line railway tunnel construction, and specifically involves an overall self -propelled hydraulic lining building and its modification methods. Background technique [0002] When the railway tunnel is located in the curve segment or part of the curve segment, the orbit of the curve segment must be widened, and the net empty surface of the tunnel changes with different width values.The continuous length of each lining section is relatively short, which causes multiple lining vehicles when fabrication is performed. [0003] The width value of the conventional tunnel lining surface is 0cm, 10cm, and 20cm. The second -lined building car is generally used in the basic model of W = 10cm. A hinge is set on the arched line.The system adjusts the panel, but the section will be reduced by 2-3cm at the arches. When the trolley is processed, the trolley lining surface will be considered and increased by 5cm. Barely can...
