Abstract
The utility model relates to a jack, in particular to an air sac type jack for jacking a box girder. The air sac type jack for jacking the box girder comprises a base seat, an air sac mechanism and a top cover, wherein a housing is wrapped around the exterior of the air sac mechanism, the housing is arranged between the base seat and the top cover, support components are arranged in the wall of the housing, an air inlet is formed in the air sac mechanism, the air inlet extends to the exterior of the housing, a safety valve is arranged on the air inlet, and the air sac mechanism comprises at least an air sac which can stretches out and draws back along the axial direction. According to the air sac type jack for jacking the box girder, the housing is arranged on the air sac type jack, the housing can prevent the air sac from being scratched and scrapped, and prolongs use life of the air sac, the housing is made of ductile material, the air sac is shrunk when the air sac type jack is not used, the housing and the air sac can be folded into the top cover and a base seat support, and therefore the air sac type jack for jacking the box girder is small in size and low in weight, and reduces labor intensity.
Description
Technical field
The utility model relates to a kind of bladder-type jack, especially a kind of bladder-type jack for jacking case beam.
Background technology
In the construction of highway and bridge, when logical when jacking case beam is installed, with jack, cast aside, jack is a kind ofly with rigidity top, to lift part as equipment, the weight-lifting equipment of jacking weight in stroke by top bracket or bottom claw, it is generally divided into two kinds of mechanical type and fluid pressure types, and mechanical jack has again rack-and-pinion and spiral two kinds, due to the little operation effort of hoisting capacity, be generally used for small-sized machine maintenance work, be not suitable for pile equipment.Two fluid pressure type jack structures are compact, and stable working, has self-locking action, therefore use extensively, its shortcoming lifting is highly limited, and lifting velocity is slow, therefore be not also suitable for the lifting of case beam.
Summary of the invention
Defect and deficiency that the utility model exists for prior art, provide a kind of bladder-type jack for jacking case beam.
The technical solution of the utility model is: a kind of bladder-type jack for jacking case beam, comprise base, air bag mechanism and top cover, described air bag mechanism is coated with crust, described shell is arranged between base and top cover, in this shell shell wall, be provided with supporting component, described air bag mechanism is provided with admission port, and this admission port extends to described housing exterior, and described admission port is provided with safety valve; Described air bag mechanism at least one can axial stretching air bag.
In said structure, described supporting component is be parallel to each other extension spring or the steel loop along air bag circumferential directions being arranged in shell shell wall.
In said structure, the slip-knot expansion link that described supporting component is socketed to form for the sleeve pipe by a plurality of various outer diameters, slip-knot expansion link top is fixed on top cover, and bottom is fixed on base.
In said structure, described air bag mechanism be two can axial stretching the air bag being arranged in juxtaposition, at two air bag diameters, be provided with flow divider valve.
Further, described flow divider valve comprises valve casing and spool, and valve casing is fixed on top cover, the tracheae of offering admission port on it and being communicated with two air bags respectively, and this tracheae is connected with two air sac sealings; The lower end of described flow divider valve is provided with strut bar, and described strut bar is telescopic faucet pipe, or nitrogen spring, or electric push rod.
The beneficial effects of the utility model are:
1, the utility model bladder-type jack comprises shell, protection air bag not by scratch, scratch, increase the service life; and shell adopts flexible material to make, inapplicable, its air bag shrinks; shell and air bag are folded in top cover and base support, and volume is little lightweight, reduce labour intensity.
2, the utility model bladder-type jack is used in jacking case beam especially, and simple in structure, quality is light, and jacking speed is fast, easy to operate, safe and reliable, long service life.
