Description
Technical field
The invention belongs to engineering machinery and make the field, relate in particular to concrete and build engineering machinery manufacturing field, particularly a kind of concrete that carries out concreting in the horizontal tilt tunnel is built chassis.
Background technology
The Hydraulic and Hydro-Power Engineering construction is usually carried out concrete and is built.Usual way is after independent installation fixes template, to carry out concrete to build.Raising along with workmanship and rate request; Requirement to engineering construction equipment also improves constantly; At present existing constructing tunnel chassis can adopt the pumping concrete to carry out the construction or adopt normal concrete to carry out the side wall construction continuously of limit crown to the tunnel, does not build crown with pumping and carries out the equipment that concrete is built simultaneously but also there is to adopt normal concrete to build the tunnel side wall, particularly in tiltedly hole tunnel is constructed; The constructing tunnel condition is various; The gradient and crooked tunnel that continuous variation is usually arranged, construction environment and complicated condition, the normal concrete that does not also have at present to adapt to the various variation in oblique hole convenient, safely, is efficiently built equipment automatically.Chinese patent 200920304405.9 discloses and a kind ofly can carry out the tunnel that side wall builds and build chassis.
The travel mechanism of general tunnel chassis adopts the steel wheel on electric power or the direct drive track of motor to move.No matter be that electric power or motor driven all need be passed through the actuator drives steel wheel usually, little in load-bearing, particularly above-mentioned travel mechanism can also be competent at when moving horizontally state.
But it is huge to formwork jumbo weight; Usually need under complex situations, construct; When there are situations such as horizontal tilt, bending in construction tunnel; Electric power and motor driven chassis can not adapt to the needs of tunneling formwork chassis, have following point: moving just of formwork jumbo just carried out after accomplishing one section construction, do not need to move at any time; Driving power device need be installed on the chassis, increases chassis weight; Under the complicated construction situation, usually occur driving instability, because of chassis need be installed four mobile devices usually, different the moving of each mobile device situation usually can not coordinate to bring potential safety hazard to construction when track moves; When the horizontal tilt state is constructed in the tunnel there be not and basis, ground stationary device the huge chassis of weight, slippage is moved and brought potential safety hazard to construction equally after very easily taking place.
Summary of the invention
The present invention discloses the oblique hole of a kind of hydraulic pressure self-propelled normal concrete according to the deficiency of prior art and has built chassis.
First problem that the present invention will solve is to realize that on the one chassis normal concrete builds tunnel side wall and pumping and build crown and carry out simultaneously; Second problem that the present invention will solve provides a kind of chassis mobile device and moves the safety and the stable problem of appearance to solve chassis; The 3rd problem that the present invention will solve is the back sliding problem of chassis in oblique hole.
The present invention realizes through following technical scheme.
