Abstract
The utility model discloses a novel tunnel trolley, comprising a stand column body, a jack and a trolley column body base, wherein a fixing column is arranged around the trolley column body base; a stand column buffering platform is arranged in the middle of the fixing column; the jack is placed on the trolley column body base. The novel tunnel trolley has the advantages that through the improvement of a trolley structure, the traditional trolley stand column base is separated from the traditional stand column, the jack is added between the base and the stand column; the fixing column is formed by adopting a steel plate on the periphery and welding the steel plate with the base; the height of the fixing column can be confirmed according to the size of the jack; the stability between the jack and the trolley stand column is ensured; during construction, operators adjust the height of the jack on the ground to ascend the bottom end of the stand column body and to control the positioning height; the operators do not need to climb to the top end of the stand column for operation; the manufacturing and machining of various tunnel trolleys are realized; the design is reasonable; the structure and the manufacturing are simple; the construction is convenient and completely practical; the manufacturing cost of the trolley is reduced; the work efficiency in the construction process is improved; the construction progress is quickened.
Description
Technical field
The utility model relates to a kind of novel tunnel chassis.
Background technology
Existing tunnel chassis technology is that the jack that adopts chassis top jack to carry out jacking and decline, will regulate definite Tunnel Design headroom size is placed on the crossbeam of chassis column top, for ease of chassis location and dismounting, set up again crossbeam on very heavy top, virtually increased chassis weight, and operating personnel need to climb to the column top and could operate when chassis location and dismounting, therefore existing tunnel chassis inefficiency, regulate positioning time than long and labour intensity is large, construction cost is higher, can not meet the requirement of well-organized management and construction progress.
The utility model content
The utility model has overcome the shortcoming in present technology, and a kind of novel tunnel chassis is provided.
The technical solution of the utility model is: a kind of novel tunnel chassis, comprise column shaft, jack and chassis shaft base, be provided with fixed leg in chassis shaft base surrounding, at the fixed leg middle part, the column buffer platform be set, jack is placed on chassis shaft base.
Be provided with road wheel on chassis shaft base.
Between fixed leg and chassis shaft base, by the chassis longeron, firmly connect.
Described fixed leg adopts Plate Welding to form in chassis shaft base surrounding.
Described fixed leg inward flange is apart from the reserved 2mm of column shaft outward flange gap.
Compared with prior art, the utility model has the advantages that: by the chassis structure is improved, original chassis column pedestal and column are separated, set up jack between its pedestal and column, surrounding adopts steel plate and base welding to form fixed leg, the fixed leg height is determined according to jack is big or small, guarantees the stable of jack and chassis column; In construction, operating personnel regulate on the ground the jack height its positioning height of control are raised in column shaft bottom, operating personnel, without climbing to the operation of column top, have realized various tunnel trolleys making processing, reasonable in design, structure and making are simple, easy construction and fully practical; Save the manufacturing cost of chassis, improved operating efficiency, accelerating construction progress in construction.
The accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of novel tunnel chassis, as shown in Figure 1, comprise column shaft 1, fixed leg 2, column buffer platform 3, jack 4, chassis shaft base 5 and road wheel 6 etc., wherein:
Fixed leg 2 is arranged on chassis shaft base 5 (the two is connected firmly), the two is connected firmly at fixed leg 2 middle parts, column buffer platform 3(to be set), column shaft 1 is placed on buffer platform 3 when not carrying out work, fixed leg 2 is placed in column shaft 1 surrounding, for guaranteeing shaft 1 axle center, vertical position, is not offset; Jack 4 is placed on chassis shaft base 5, for the height of adjusting post shaft 1.Be provided with road wheel 6 on chassis shaft base 5.Chassis longeron 7 is used T-shaped bolt and fixed leg 2 and chassis shaft base 5 fixing, for the chassis two ends vertically are connected firmly.
In chassis shaft base 5 surroundings, adopt Plate Weldings to form fixed legs 2, the fixed leg height is determined according to the jack size, while guaranteeing that jack 4 tops rise to extreme position, the fixed leg top is higher than jack top 30cm at least.
Fixed leg 2 is square-section, at fixed leg 2 inward flanges apart from the reserved 2mm of column shaft 1 outward flange gap, in conjunction with on-the-spot tunnel longitudinal gradient size cases, can set up sliding agent at fixed leg 2 inward flanges, when reducing 1 lifting of column shaft and fixed leg 2 frictional force; Face the outage degree by the reserved 30cm of chassis central side (rising to chassis shaft base position) and do not seal, so that the operation jack uses.
Operating principle of the present utility model is: control chassis vault absolute altitude by the height of jack 4 adjusting post shafts 1, by adjusting, control and meet the tunnel clearance dimensional requirement; Build and completely descended by jack 4 adjusting post shafts 1 while needing form removal until two lining concretes, chassis and concrete are broken away from and reach stripping result; Increase fixed leg 2 in column shaft 1 lower end surrounding, shaft is not offset in axle center when height is regulated or is placed in inactive state, guarantee stability and safety; When jack 4 needs to change or moves, allow shaft 1 bottom be placed on buffer platform 3; On chassis shaft base 5, road wheel 6 is set, thereby realizes the purpose of trolley running, increase work efficiency.
Claims (5)
