Abstract
A lifting jack travelling vehicle used for moving a caisson comprises a lifting jack used for jacking a caisson and a travelling vehicle, wherein the travelling vehicle comprises a frame-shaped vehicle body and travelling wheels arranged at the bottom of the vehicle body, a base plate is arranged at the bottom of the vehicle body, and the lifting jack is fixedly arranged in the middle of the base plate; a plurality of spring assemblies are uniformly distributed in the vehicle body at the periphery of the lifting jack; each spring assembly comprises an inner sleeve, an outer sleeve, a spring, a connecting rod and a long screw nut, the inner sleeve, the spring and the outer sleeve are movably sheathed into a whole body; and a connecting rod is arranged at the bottom of the inner sleeve, the bottom of the connecting rod is screwed with the long screw nut which is fixedly connected with the base plate. The lifting jack travelling vehicle has a simple structure and safe in operation. The lifting jack and the base plate are assembled on the travelling vehicle together, the moving, positioning and retracting of the lifting jack in the field can be completed by simply manual pushing and pulling so as to realize the move of the caisson without the matching of other machines, so that the investment of the precast yard and the input of manpower and machinery equipment in the construction can be saved, and the efficiency of work staff can be improved.
Description
Technical field
The utility model relates to the auxiliary equipment of using in a kind of building construction process, particularly a kind ofly is used for the jack walking car that agalloch eaglewood moves.
Background technology
In building construction process, the frequency of utilization of caisson is very high, and the fortune process that goes out of caisson is: the jacking of pedestal district, travelling platform on the caisson; Jacking caisson in vertical shift district spreads out travelling platform, vertical shift car on the caisson; Rolling district jacking caisson, the vertical shift car is withdrawn from, tiltedly unwheeling on the caisson; Heavy duty tiltedly unwheeling is glided along the ramp; The haul of caisson floating.Therefore, traditional caisson goes out fortune process complexity, and caisson is from great, and its work such as mobile, in place all needs to drop into a large amount of human and material resources and plant equipment, and not only serious wastes time and energy, and influences engineering efficient, but also has very big potential safety hazard.
Summary of the invention
The utility model is the deficiency at traditional move mode of caisson, provides a kind of simple to operate, is used for the jack walking car that caisson moves safely and efficiently.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind ofly be used for the jack walking car that caisson moves, comprise the jack and the walking dolly that are used for the jacking caisson, described walking dolly comprises the car body of frame-like and is arranged on the road wheel of car body bottom, backing plate is equipped with in the car body bottom, jack fixed installation backing plate middle part; Be evenly equipped with a plurality of mains assemblage of spring in the car body of described jack periphery; Described main assemblage of spring comprises inner sleeve, outer sleeve, spring, connecting rod and long nut, and wherein inner sleeve, spring and outer sleeve movable set are one; Connecting rod is equipped with in the bottom of inner sleeve, and the bottom and the long nut of connecting rod spin, and long nut and backing plate are affixed.
Compare with the mobile device of traditional caisson, the utility model is simple in structure, handling safety.Jack and backing plate are assemblied on the walking car together, that simple manpower push-and-pull can be finished is mobile, in place in the field of jack, withdraw from, realize moving of caisson, do not need other machineries to cooperate, save the manpower in precasting yard investment and the construction, the input of plant equipment, improved staff's efficient.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the main assemblage of spring structural representation.
Among the figure: road wheel 1, backing plate 2, car body 3, main assemblage of spring 4, jack 5, inner sleeve 6, spring 7, outer sleeve 8, connecting rod 9, long nut 10.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing 1-2, in the present embodiment, thisly be used for the jack walking car that caisson moves, comprise the jack 5 and the walking dolly that are used for the jacking caisson, described walking dolly comprises the car body 3 of frame-like and is arranged on the road wheel 1 of car body bottom, steel backing plate 2 is equipped with in car body 3 bottoms, jack 5 fixed installation backing plates 2 middle parts.Be evenly equipped with a plurality of mains assemblage of spring 4 in the car body 3 of jack 5 peripheries, the quantity of the main assemblage of spring 4 in the present embodiment is four, is fixedly mounted on the corner location of car body 3 respectively.Main assemblage of spring comprises inner sleeve 6, outer sleeve 8, spring 7, connecting rod 9 and long nut 10, wherein inner sleeve 6, spring 7 and outer sleeve 8 movable sets are one, it is the outside that spring 7 is sleeved on inner sleeve 6, spring 7 and inner sleeve 6 are sleeved on outer sleeve 8 inside together, and inner sleeve 6 can move up and down in outer sleeve 8, and outer sleeve 8 is stretched out in the upper end of inner sleeve 6; Connecting rod 9 is equipped with in the bottom of inner sleeve 6, and the bottom of connecting rod 9 and long nut 10 spin, and the bottom of long nut 10 and backing plate 2 are affixed.
Backing plate bottom surface and terrace have the 40mm gap when guaranteeing zero load by long nut is regulated, and prevent that moving process is merely able to the billet soffit and touches terrace, cause to move and are obstructed.
Operating principle of the present utility model is: during no duty, and the main assemblage of spring of under the environment that the self gravitation of jack and backing plate exists, installing, its medi-spring is in relaxation state.When jack boosts, behind the jack piston contact caisson, so because top lift that the elastic force that the decrement of the moderate jack pair spring of coefficient of elasticity of the spring of selecting for use (the gap 40mm between billet bottom surface and jack basis terrace) produces gets up to need much smaller than the caisson jacking, this moment, spring was compressed, backing plate descends, after jack basis terrace contacts fully, continue to increase top lift, be elevated to certain altitude until caisson, the top lift that increases passes to the jack basis by backing plate, and all load before the jack piston contact caisson are born by car body.During the jack release, its process with boost on the contrary, backing plate raises after finishing, and keeps original gap 40mm between terrace.
