Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following examples.

[0033] The structure of the angle-adjustable and laterally adjustable mobile trestle provided by this embodiment is as follows: figure 1 As shown, it includes at least walking wheel set 1, rear outrigger 2, main beam 3, center gutter formwork assembly 4, longitudinal moving trolley 5, inverted arch formwork assembly 6, guide beam 7, middle outrigger 8, front support Leg 9, tug mechanism 10 and electro-hydraulic system.

[0034] The rear outrigger structure is as figure 2 As shown, it includes a rear outrigger crossbeam 21, a rear outrigger cylinder 22, and a sliding connection seat 23. The rear outrigger cylinder 22 is symmetrically fixed on the rear outrigger crossbeam 21, and the main beam 3 is movably connected to the rear outrigger crossbeam 21. The relative sliding between the...

Abstract

The invention provides an angle-adjustable and transverse-adjustable movable trestle. The angle-adjustable and transverse-adjustable movable trestle at least comprises a walking wheel set, a rear supporting leg, a main beam assembly, a central ditch formwork assembly, a longitudinal moving trolley, an inverted arch formwork assembly, a guide beam assembly, a middle supporting leg, a front supporting leg, a tug mechanism and an electro-hydraulic system; the rear supporting leg and the front supporting leg are fixedly installed below the tail end and the head end of the main beam respectively; the middle supporting leg is movably installed below the main beam; a main beam sliding shoe mechanism is installed between the main beam and the middle supporting leg; an auxiliary supporting leg is installed below the head end of a guide beam; and a roller mechanism is arranged at the tail end of the guide beam. According to the movable trestle, the angle of the guide beam can be adjusted according to the specific situation of an inverted arch excavation area in front of a tunnel, use is convenient, and the construction efficiency can be further improved; the extension and retraction of the guide beam are not influenced while the angle is adjusted; and the front supporting leg is used in cooperation with the rear supporting leg in the movable trestle, the overall transverse position of the main beam in the movable trestle can be adjusted, use is convenient, and the construction efficiency can be further improved.

Description

technical field [0001] The invention provides a large-span walking type mobile trestle, in particular relates to a movable trestle with adjustable angle and horizontal direction, which belongs to the technical field of tunnel construction. Background technique [0002] As the tunnel mechanized rapid construction technology system has not yet been completed, many key technical problems have not yet been broken through, resulting in great differences in construction progress and many hidden dangers of accidents. A comprehensive analysis of the main process of tunnel construction (tunnel excavation, initial support, inverted arch construction, waterproof board laying and hanging, secondary lining concrete pouring and trench cable channel construction, etc.) found that the construction process at the mobile trestle took a long time, and some processes The inability to synchronize construction has seriously restricted the progress of tunnel construction and has become a key proce...
