Description
Technical field
Large channel side slope bed course spreading machine of the present utility model belongs to hydraulic engineering mechanism field.
Background technology
at present, what the large channel construction adopted is the side slope bedding material that first paves, then lay antiseepage film thereon, on film with the machinery lining concrete that paves, use finally the form of construction work of machine cuts structural joint, the side slope bedding material generally adopts Manual, the mode that loader paves or tipping truck paves is carried out, the complete rear vibrating roller of using paves, vibrating plate or vibro-rammer vibratory compaction, this kind form of construction work speed that paves is slow, artificial operation repeatedly on the face of storehouse often causes the bedding plane structural damage, and because vibration facility construction area is little, make the closely knit lack of homogeneity of bedding material, the bedding plane poor flatness, work efficiency is low, cost of labor is high.Because artificial bedding plane and mechanical lining planeness are often inconsistent, very easily cause the concrete thickness after paving inhomogeneous, the bad control of the structural joint degree of depth, cause cutting brokenly antiseepage film, the generation of the problems such as waste concrete.
through retrieval, existing application number is 88220120.4, denomination of invention is " concrete lining machine for single-slope ditch ", application number is 200620078872.0, denomination of invention is " large channel concrete lining machine ", application number is 200610012975.1, denomination of invention is " large span complex channel concrete casting machine ", application number is 200720200605.0, denomination of invention is " water channel concrete digital automatic lying equipment ", application number is 200920104488.7, denomination of invention is 1 application for a patent for invention of 4 utility models of " a kind of modes of discharging, vibrating and sliding masonry machine ".
Wherein, there is following defect in " concrete lining machine for single-slope ditch ":
1. high, the function imperfection of cost.Its working method is full hydraulic drive, crawler travel, chain scraper formula or spiral cloth, mechanical type concrete vibrating from bottom to top, only is adapted to≤the short slope lining cutting of 7m.Need advanced import of complete machines automatic guide reliably and the automatic capturing system of 120 ~ 1,500,000 yuan of configurations, otherwise can't work, it is helpless for vibrating of the cementing gravel bed of material;
2. the execution conditions requirement is high, and compliance is not good.Must carry out feed with concrete delivery truck at the bottom of canal, and need special-purpose charging equipment, often be subjected to the restriction of canal bottom width degree, builder's road, groundwater table, liner structure and concrete delivery truck to the destroying infection of canal base plinth, almost can't use.
3. main machine structure is complicated, the cloth weak effect.It designs for laying the stream wet concrete from bottom to top, does not conform to convention, make thus that main machine structure is complicated, power is large, cloth not in time, inhomogeneous, very easily cause concrete from clear, to such an extent as to limited main frame lining cutting function.
Rear four by the conveyor feed, is arranged on the horizontal auger of forming cart and carries out sub-material, and forming cart moves up and down the single width fluid concrete molding mode operation that paves along domatic, and not only the closely knit quality of concrete block width and width lap-joint can't guarantee but also work efficiency is low.
Above-mentioned five kinds of coffering machines, casting machine, automatic lying equipment, masonry machine only adapt to the concrete of building thickness≤0.10m, must vibrate and make concrete compaction by vibrating spear, its common problem is that work efficiency is low, can only pave with the concrete of certain fluidity, the discrete materials such as the stiff coarse sand that can not pave, sandy gravel mixture, modified cement soil, other Modified soil and dry mortar.
Summary of the invention
The purpose of this utility model is to provide a kind of and integrates material loading, cloth, the side slope bed course paves and closely knit moulding several functions, channel building paver that can a construction molding at the bottom of canal shoulder, canal slope and part canal.
The purpose of this utility model is achieved in that large channel side slope bed course paver is comprised of material loading, walking lifting, cloth, vibration moulding four parts, and material loading part is comprised of the charging belt machine that moves towards to lay along the canal shoulder.Walking lifting part respectively by along move towards the guide rail of laying at the bottom of canal shoulder, canal, the travelling gear that is erected at walking wheels on guide rail, wraps in the outer roller box of walking wheels, meshes with the walking wheels, the motor of linked gear axle, the hydraulic cylinder piston rod that is connected with roller box, the horizontal shore that is connected with cylinder barrel form.Cloth part by the feeding belt machine, be erected at burden charging carriage and OPS on frame, connect the feed bin that is contained in frame one side and form, frame is a cuboid cavity frame, its two ends are connected with horizontal shore is inner respectively.The vibration moulding part is comprised of the inside and outside walking beam that even is contained in feeding belt machine frame chamber and frame is outer, and frame sequentially connects spring base, connection cord, walking beam are housed from top to bottom, and two beam upper surfaces are connected with vibrating motor.
Owing to carrying out technique scheme, make this paver can be exclusively used in the construction of side slope bedding material in the large channel construction, mechanization degree is high, integrate material loading, cloth, levelling and hit real moulding several work paves, greatly reduce artificial input, reduce labour intensity, improve speed of application and workmanship, the reduction duration, reduce engineering cost.The machine can realize canal shoulder, canal slope and the one-shot forming of part canal foot mat, and after construction is completed, planeness is higher, and compactness meets technical requirements.
