Abstract
The utility model discloses a multi-stage hydraulic jacking device for building a deck sheet. The multi-stage hydraulic jacking device comprises an oil pump communicated with an oil groove through an oil inlet pipeline, wherein an outlet of the oil pump is communicated with an inlet of a three-way four-position valve through an oil outlet pipeline; an overflow valve is connected with the oil outlet pipeline; a first oil port of the three-way four-position valve is communicated with an inlet of a first oil path distributer through a first oil pipe; a plurality of outlets of the first oil path distributer are respectively communicated with inlets of a plurality of cylinders through connection pipelines in a one-to-one correspondence manner; a flow adjusting valve and a two-position two-way valve are arranged on each connection pipeline; outlets of the plurality of cylinders are communicated with an inlet of a second oil path distributer in a one-to-one correspondence manner, and an outlet of the second oil path distributer is communicated with a second oil port of the three-way four-position valve through a second oil pipe. By adopting the device, low welding, large-displacement jacking and descending of the deck sheet are achieved.
Description
Technical field
The utility model relates to jacking apparatus, relates in particular to deck sheet construction and uses the multistage hydraulic jacking apparatus.
Background technology
Characteristics such as it is big that large structure has structure, and weight is heavier, deck sheet are built 50% work that accounts for structure building; The deck sheet adds needs sandblast man-hour, paint, stand up or the like operation, and device need lifted by crane and transfer to its transportation often, generally adopts gauntry crane and crawler crane; Gauntry crane can only be at fixing regional movement among a small circle; Crawler crane often cost is very high, and the speed of motion is very slow, and it is low to move efficient.The manufacture process of deck sheet is most effective to be downhand welding; The people welds (low level welding) at the ground of standing; But this build process deck sheet bottom space is smaller; The single-stage cylinder apparatus carries out jacking because insufficient height can't be placed on its bottom, and flat bed transport vehicle highly also can't directly get into sheet bottom, deck.
Summary of the invention
The purpose of the utility model is to provide a kind of body height that effectively reduces oil cylinder; Make the overall extension elongation of piston rod reach flat bed transport vehicle and start shipment height; Realize deck sheet low level welding, the deck sheet of big displacement jacking and decline is built and is used the multistage hydraulic jacking apparatus.
The deck sheet of the utility model is built and is used the multistage hydraulic jacking apparatus; It comprises the oil pump that is connected with oil groove through chargine line; The outlet of described oil pump is connected through the import of fuel-displaced pipeline with a three-way four-position valve; On described fuel-displaced pipeline, be connected with by pass valve; First hydraulic fluid port of described three-way four-position valve is connected through the import of first oil pipe with the first oil circuit distributing box; A plurality of outlets of the described first oil circuit distributing box are provided with through the corresponding one by one connection of the connecting line and the import of a plurality of oil cylinders respectively; On each described connecting line, be respectively arranged with flow control valve and two two-way valves, the outlet of described a plurality of oil cylinders is provided with the corresponding one by one connection of the import of the second oil circuit distributing box respectively, and the outlet of the described second oil circuit distributing box is connected with second hydraulic fluid port of described three-way four-position valve through second oil pipe.
The utility model device adopts the multi-stage oil cylinder jacking apparatus, effectively reduces the body height of oil cylinder, makes the overall extension elongation of piston rod reach flat bed transport vehicle and starts shipment height, realizes deck sheet low level welding, big displacement jacking and decline.
Utilize this device can realize the low level construction of deck sheet, the oil cylinder elemental height is about 500～800mm, and the jacking overall height surpasses 1500mm.
Description of drawings
Accompanying drawing is that the deck sheet of the utility model is built the structural representation with the multistage hydraulic jacking apparatus.
The specific embodiment
Below in conjunction with the specific embodiment and embodiment the utility model is described further.
The multistage hydraulic jacking apparatus is used in deck sheet construction like the utility model shown in the drawings; It comprises the oil pump 2 that is connected with oil groove through chargine line; The outlet of described oil pump 2 is connected through the import of fuel-displaced pipeline with a three-way four-position valve 1; On described fuel-displaced pipeline, be connected with by pass valve 3; First hydraulic fluid port of described three-way four-position valve 1 is connected through the import of first oil pipe with the first oil circuit distributing box 4; A plurality of outlets of the described first oil circuit distributing box 4 are provided with through the corresponding one by one connection of the connecting line and the import of a plurality of oil cylinders 7 respectively; On each described connecting line, be respectively arranged with flow control valve 6 and two two-way valves 5, the outlet of described a plurality of oil cylinders is provided with the corresponding one by one connection of the import of the second oil circuit distributing box 8 respectively, and the outlet of the described second oil circuit distributing box is connected with second hydraulic fluid port of described three-way four-position valve through second oil pipe 9.
The working process of this jacking apparatus is:
After oil pump 2 is started working, carry out the pressure control control of total system, by three-position four-way valve 1 control of going up and down through by pass valve 3.
Oil cylinder rises and controls: three-position four-way valve 1 right side electromagnetic valve energising; Hydraulic oil gets into a plurality of branch roads respectively through the first oil circuit distributing box 4, via two two-way valves 5, flow control valve 6; Get into the lower oil cavitie of a plurality of oil cylinders 7; The hydraulic oil of the upper oil cavitie of a plurality of oil cylinders 7 is got back to three-position four-way valve 1 through the second oil circuit distributing box 8, returns fuel tank, realizes the jacking work of oil cylinder;
Oil cylinder descends and controls: three-position four-way valve 1 left side electromagnetic valve energising, and hydraulic oil through second oil pipe, 9 to second oil circuit distributing boxs 8, gets into the upper oil cavitie of a plurality of oil cylinders 7 from oil pump then; The hydraulic oil of a plurality of oil cylinder 7 lower oil cavities is via flow control valve 6; Two two-way valves 5 get into the first oil circuit distributing box 4, are gathered by the first oil circuit distributing box 4 and get back to three-position four-way valve 1; Return fuel tank, realize the decline work of oil cylinder.
