Problems solved by technology

[0002] Traditional construction trestles are divided into simple trestles and integral trestles. Simple trestles are just two separate bridge plates, and other equipment is needed for movement; integral trestles include trestle main girders, front and rear ladders, and self-walking systems, but there is no Inverted arch formwork, central ditch trolley, and front-end telescopic trestle and other components, the functions of the application are also difficult to meet the requirements
The above-mentioned traditional trestle bridges require a lot of templates in use, and require a lot of manpower to complete the corresponding construction operations. When excavating the soil in the inverted arch section, it needs to be excavated first, and then backfilled after the excavation, which is convenient for tunnel construction. The slag-discharging trucks pass through, and when the inverted arch operation reaches the position, the backfilled soil needs to be excavated and transported out of the hole again. The process is repeated, complicated, and inefficient, resulting in low construction efficiency and cumbersome operations, and poor construction quality

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as Figure 1-Figure 4 As shown, the multifunctional telescopic inverted arch trestle of the present invention comprises trestle main girder 5, front climbing ladder 16, rear climbing ladder 1, walking trolley 8, telescopic trestle 17, inverted arch formwork 26 and center ditch formwork 22, and walking trolley 8 installs It is placed under the trestle main girder 5 and can walk forward and backward. The front end of the trestle main girder 5 is placed on the main beam 29, and the main beam 29 is installed on the walkable main crawler chassis through the vertical main lifting hydraulic cylinder 30 and the main movable column 31. 28, the telescopic trestle 17 is positioned at the front portion below the trestle main girder 5 and can move forward and backward. The front portion of the telescopic trestle 17 is placed on the telescopic trestle crossbeam 18, and the re...

Abstract

The invention discloses a multifunctional stretchable inverted-arch trestle. The multifunctional stretchable inverted-arch trestle comprises a trestle girder, a front ladder stand, a back ladder stand, a walking cart, a stretchable trestle body, an inverted-arch formwork and a central furrow formwork; the walking cart is installed below the trestle girder, the stretchable trestle body is located at the front portion below the trestle girder, the front portion of the stretchable trestle body is arranged on a stretchable trestle body beam, the back portion of the stretchable trestle body is movably installed on the trestle girder through connecting plates, and the stretchable trestle body beam is installed on a walking auxiliary caterpillar band chassis through vertical auxiliary lifting hydraulic cylinders and auxiliary movable stand columns; the inverted-arch formwork and the central furrow formwork are sequentially installed in the middle and at the back portion below the trestle girder from front to back and move back and forth through the walking cart. According to the multifunctional stretchable inverted-arch trestle, the trestle girder, the stretchable trestle body, the inverted-arch formwork, the central furrow formwork and end sealing plates are designed into an integrated device, multiple working procedures can be carried out at the same time, the construction period is greatly saved, the construction efficiency is improved, the labor intensity of workers is reduced, the construction quality is guaranteed, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a construction trestle, in particular to a multifunctional telescopic inverted arch trestle. Background technique [0002] Traditional construction trestles are divided into simple trestles and integral trestles. Simple trestles are just two separate bridge plates, and other equipment is needed for movement; integral trestles include trestle main girders, front and rear ladders, and self-walking systems, but there is no Inverted arch formwork, center ditch trolley, and telescopic trestle at the front end are also difficult to meet the requirements in application. The above-mentioned traditional trestles require a lot of templates in use, and a large amount of manpower is required to complete the corresponding construction operations. When excavating the soil in the inverted arch section, it is necessary to excavate first, and then backfill after the excavation, so as to facilitate the excavation in the tunnel. The slag trucks ...
