Description
Technical field
The present invention relates to the underground construction technical field, be specifically related to a kind of job practices that is used for deep pit digging.
Background technology
Along with the continuous development of urban construction, various types of underground constructions, deep foundation engineering get more and more.Efficiently, the construction method of deep foundation ditch of economy, energy-saving and environmental protection seems particularly important.At present, there is following problem in the excavation construction that uses conventional method to carry out deep foundation ditch:
(1) servicing unit such as foundation ditch support influences the function performance of conventional digging machine, particularly digs deeply greater than after 20 meters, cut the earth below foundation ditch supports and fetch earth, and conventional digging machine is subjected to the restriction of swing arm height, and is very difficult even can not bring into play usefulness;
(2) existing hand control digging machine potential safety hazard is many, and digging has a lot of uncertain factors under deep foundation ditch, influences personal safety;
(3) conventional digging machine economy, the feature of environmental protection is poor, fuel consume is big, blowdown is serious problem are inevitable;
(4) existing digging machine function singleness, deep foundation pit construction are except that digging muck haulage, and it is quite big to set up the support works amount.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, special requirement at underground construction diggings such as deep foundation ditch, pneumatic caissons, a kind of job practices that is used for deep pit digging is provided, this job practices utilizes the excavation part of digging machine to cut the earth freely below its brace summer and brace summer such as sets up at work, make digging machine itself possess walking function simultaneously, realize the full-automation of excavating.
The object of the invention realizes being finished by following technical scheme:
A kind of job practices that is used for deep pit digging adopts digging machine to excavate, and digging machine comprises bucket assembly and brace summer thereof, it is characterized in that this job practices is by being provided with the selection that running gear realizes finishing the excavation position in the digging machine bottom; Digging machine is arranged to along vertical supporting beam can be along vertical flexible vertical extensible canopy, to realize the adjustment to the working depth of digging machine; Digging machine is arranged to along horizontal supporting beam can be along the horizontal extensible canopy of transversal stretching, to realize the adjustment to the bucket working range of digging machine; After finishing above-mentioned selection adjustment, finish excavation, above crawler belt, install and fix vertical extensible canopy, the two ends of horizontal extensible canopy are connected and fixed with vertical extensible canopy respectively.
Described vertical extensible canopy is made up of sleeve and oil cylinder, realizes this beam stretching in vertical direction by oil cylinder control.
Described horizontal extensible canopy is made up of sleeve and oil cylinder, realizes in the horizontal direction flexible of this beam by oil cylinder control.
Be provided with vertically telescopic outrigger below digging machine, this supporting leg is used to support digger, so that the adjustment of running gear, maintenance.
By the revolution rotating disk being set, drive the 360 degree rotations on horizontal plane of bucket assembly by this rotating disk in bucket assembly bottom.
Advantage of the present invention is safety: adopt telecontrol engineering, make operating personnel not need to enter tens meters dark underground work, avoided the generation of personal safety accident;
Multi-functional: can be comprehensive, multi-angle excavates, because the bucket assembly can 360 degree rotations,, can make bucket function such as realize that crowd shovel, backhoe and side are dug according to the actual job situation at scene, effectively dead angle earth is removed.Telescopic working arm can be regulated the shoveling scope automatically under the situation that does not change the working arm height, so just can greatly reduce operation height, and traditional digging machine must lift big arm is high when closely cutting the earth, so just increase operation height, can be subjected to the restriction of supporting facility such as brace summer.
High efficiency: owing to the digging machine of the equal dipper capacity of the little ratio of dynamic moment of inertia is compared, about efficient doubles;
Energy saving: adopt the electric-powered cell arrangement of a cover, drive the operation of flexible bucket, more save the energy than internal combustion engine formula digging machine.According to initial estimate, adopt the industrial electricity charge of time-sharing ammeter, energy-conservation about 40%;
The feature of environmental protection: adopt driven by power to avoid the exhaust pollution that digging machine produced and the noise pollution of internal combustion engine formula.
