Abstract
An unfolded type tunnel construction lining trolley comprises a lining trolley frame, wherein a U-steel base is welded to the bottom of the lining trolley frame in a fixed mode, and operating platforms are arranged on the lining trolley frame in a four-layer mode. A rebar mesh piece is distributed on each operating platform. Ladder stands, a guardrail, a wind pipeline and a water pipeline are distributed on the outer side of each operating platform. The lining trolley frame is made by adopting of H-shaped steel and is composed of parts such as longitudinal beams, crossbeams, bottom holding beams, inclined supports and support cross bars. The constituent parts are connected in a welding mode. The unfolded type tunnel construction lining trolley has the advantages of being simple in structure, light in weight, low in manufacturing price, convenient to install, move and dismantle, and suitable for the characteristic of a tunnel construction that mechanical equipment moves frequently. The working methods that 'the lining trolley is unfolded when a construction is processed', 'the lining trolley is folded back before being moved' and 'a loading machine is lifted and moved to a place' are adopted, the operating platforms can be folded and unfolded freely, operation that the construction lining trolley is moved to a place is easy, safe, fast and convenient, moving time of the lining trolley is shortened, construction cost is reduced, and construction schedule is accelerated. The unfolded type tunnel construction lining trolley is applicable to excavating, retaining and protecting constructions of tunnel projects such as a road, a railway and a water conservancy project.
Description
Technical field
The utility model relates to the tunnel excavation construction equipment, particularly a kind of expansion tunnel construction trolley.
Background technology
In tunnel construction, because the construction chassis moves frequently, be subjected to construction environment and spatial constraints, usually the construction chassis moves comparatively difficulty in place, take the long period, and vehicle body is easily impaired, has certain construction safety risk, particularly in the location of features as poor geologic condition, convenient and practical, safe and reliable construction chassis is the necessary condition that tunnelling works carries out smoothly.
Summary of the invention
The utility model is to move easily impaired problem of difficulty in place, vehicle body in order to solve tunnel construction trolley, and a kind of expansion tunnel construction trolley is provided.
The purpose of this utility model is achieved in that
A kind of expansion tunnel construction trolley, it comprises bogie frame, and the bogie frame bottom welding is fixed with the channel-section steel base, and minute four layers of setting operation platform are laid with reinforced mesh on the bogie frame on the operating platform, and the outside is laid with cat ladder, guardrail and wind, water pipeline.
Above-mentioned bogie frame adopts i iron to make, and is comprised of longeron, crossbeam, backing beam, diagonal brace, supporting bar, and each ingredient connected mode is welding.
Above-mentioned backing beam adopts to tie up about two i iron to weld and is formed by connecting, and is welded in the bottom surface of bogie frame.
Above-mentioned supporting bar divides three layers of setting, by the D100 steel pipe that is welded in crossbeam i iron inboard, and the D80 steel pipe of interior insertion formation, supporting bar is scalable, lay reinforced mesh on it and form operating platform, operating platform outwards launches by regulating supporting bar length.
Above-mentioned base adopts channel-section steel to make, and two ends are arcuate structure, and is upwards crooked.
The utility model has been obtained following technique effect:
The expansion tunnel construction trolley that the utility model provides, simple structure, weight is lighter, and cost is lower, installs, moves and convenient disassembly, is fit to frequently characteristics of tunnel construction machinery equipment moving; By the telescopic adjustment of supporting bar, each layer operation berm width of chassis arranged on left and right sides is realized adjustable, and constructability is guaranteed safety; After by the supporting bar that shrinks arranged on left and right sides the operating platform that launches being shunk, adopt loader to lift in the backing beam of bogie frame bottom, make chassis realize safety, mobile in place fast; Construction is laid along the chassis outside with wind, water pipeline and is fixed to each layer operation platform, wind, water pipeline installation, dismounting and easy to use; The outside of each layer operation platform adopts reinforced mesh to be layed on the supporting bar, and deployable to the country rock face, but up and down scope of operation personnel cross-operation in the time of the Effective Raise construction safety, has also reduced construction cost, has accelerated construction speed.

Described bogie frame adopts i iron to make, and partly is comprised of longeron 2, crossbeam 3, backing beam 4, diagonal brace 5, supporting bar 6 etc., and each ingredient connected mode is welding.Described backing beam adopts to tie up about two i iron to weld and is formed by connecting, and is welded in the bottom surface of bogie frame.Described supporting bar divides three layers of setting, by the D100 steel pipe that is welded in crossbeam i iron inboard, and the D80 steel pipe of interior insertion formation, supporting bar is scalable, lay reinforced mesh on it and form operating platform, operating platform outwards launches by regulating supporting bar length.Described base adopts channel-section steel to make, and two ends are arcuate structure, and is upwards crooked.
Implementation step of the present utility model is as follows:
1, adopts three groups of steel structures of i iron welding production ∏ type support, two groups of backing beams, at inboard minute three layers of welding D100 steel pipe of the crossbeam at every group of steel structure ∏ type support two ends, and by longeron, backing beam, diagonal brace and channel-section steel base, it is in aggregates to adopt welding manner that three groups of steel structure ∏ type supports are connected, and forms bogie frame;
2, in the D100 steel pipe, insert the D80 steel pipe, form telescopic supporting bar;
3, lay fixedly reinforced mesh at the supporting bar of bogie frame and both sides, form operating platform;
4, be welded and fixed cat ladder, guardrail and wind, water pipeline in the bogie frame outside;
5, adopt loader to lift on the backing beam of bogie frame bottom, in place by will the construct movement of chassis of loader;
6, transfer the supporting bar of long both sides after, lay fixedly reinforced mesh, each layer operation platform is expanded to the country rock face, connect wind, water pipeline can drop into tunnel excavation and construct;
7, after construction is finished, remove the reinforced mesh on the two-side supporting cross bar, shrink supporting bar, and remove wind, water pipeline can move the construction chassis by loader.
