An integral self-propelled hydraulic lining trolley and its modification method

A lining trolley, self-propelled technology, applied in shaft lining, tunnel lining, shaft equipment and other directions, can solve the problems affecting the excavation progress of the tunnel face, increasing the number of lining trolleys, and increasing the cost of tunnel construction. The trolley modification process is simple, the trolley investment is reduced, and the effect of the excavation progress is not affected.

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] like figure 1 Show, figure 1 For the structure diagram of the owner skeleton 1, the vertical skeleton 3 and the beam 2 are set on the upper end of the main setting of the owner's skeleton 1. figure 2 The structure diagram of the structure of the section width W = 50+5cm, combined figure 2 Show, the overall self -propelled hydraulic lining car of the present invention, including the overall template, the platform car owner skeleton that supports the overall template 1. The vertical skeleton 3 and beam 2 support the overall template, the left and right sides of the overall template arched waist waist19-20 degrees positioning of the first hinge 13 and the second hinge 11 respectively; Figure 4 , Mark 18, that is, the position of the position of the second hinge 13.

[0032] Also, combine Figure 4 The lining building of the present invention also includes the vertical adjustment block 19 of the vertical skeleton 3 height, and the horizontal adjustment block 20 of the beam 2 wid...

Embodiment 2

[0042] Such as image 3 It is shown in the structural schematic diagram of the structure of the invention on the cross section w = 30+5cm, and figure 2 The difference is that the designs and width of the interchanged section after the use of hydraulic system 1 and hydraulic system 2 4 and the hydraulic system 2 will use the hydraulic oil cylinder 16 and the mechanical screw 17 to adjust the overall template and the platform car owner skeleton.The distance, and replaced the horizontal adjustment block and vertical adjustment block suitable for the cross -section after the change, and make full use of the hinge's directional rotation function to adjust the overall template angle of the lining car, so that the outline of the outline of the lining car template and the design liningThe net empty section is in line to meet the design size and then positioned the trolley.

Embodiment 3

[0044] Such as Figure 4 It is shown in the structural schematic diagram of the structure of the invention on the cross section w = 10+5cm, and figure 2 Concentrate image 3 The difference is that the designs and width of the interchanged section after the use of hydraulic system 1 and hydraulic system 2 4 and the hydraulic system 2 will use the hydraulic oil cylinder 16 and the mechanical screw 17 to adjust the overall template and the platform car owner skeleton.The distance, and replaced the horizontal adjustment block and vertical adjustment block suitable for the cross -section after the change, and make full use of the hinge's directional rotation function to adjust the overall template angle of the lining car, so that the outline of the outline of the lining car template and the design liningClean air breaks in line to meet the design size and then position the car car. Figure 4 The angle of the winning bid is 19 ° 19′45 ″.

Abstract

The invention relates to the field of single-track railway tunnel construction, in particular to an integral self-propelled hydraulic lining trolley, comprising an integral formwork, a main frame of the trolley supporting the integral formwork, a vertical framework and a beam supporting the integral formwork, the vertical framework and the crossbeam It is arranged on the upper end of the main frame of the trolley, and the first hinge and the second hinge are respectively arranged at the positions of 19-20 degrees on the left and right sides of the integral formwork. The lining trolley of the invention has good integrity, simple operation and strong applicability, can satisfy the construction of multiple clearance sections of a single-track railway, and solves the problem that one lining trolley is suitable for multiple lining sections.

Description

Technical field [0001] The present invention involves the field of single -line railway tunnel construction, which 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 c...
