Abstract
The invention relates to a front support beam lifting system which comprises two pier body supporting seats, support hydraulic cylinders respectively and vertically arranged on the two pier body supporting seats and a hydraulic station, wherein the two support hydraulic cylinders are respectively connected to the hydraulic station; and the top ends of the piston rods of the two support hydraulic cylinders are respectively connected to the bottom end of a front support beam. When the system is in use, firstly, the two support hydraulic cylinders are vertically arranged on the pier body supporting seats of a bridge pier; the hydraulic station is started to provide power to the support hydraulic cylinders, so that the two support hydraulic cylinders act simultaneously so as to lift the front support beam, as well as a connection truss and a bridge of the nose which are fixed at two ends of the front support beam, to required heights; and by virtue of operating the single support hydraulic cylinder, the front support beam can be regulated to a horizontal position. The front support beam lifting system can be used for rapidly and accurately lifting the front support beam and effectively avoiding potential safety hazards existing in manual operations.
Description
Technical field
The present invention relates to a kind of bridge construction device, be specifically related to a kind of front support crossbeam hoisting system.
Background technology
In recent years, along with the continuous growth of highway in China, high speed railway construction scale, more and more higher to the demand of advanced construction equipment and technology.Downstriker, the non-self-propelled moveable formwork bridge fabrication machine of upstriker since last century the nineties be widely used in the bridge construction construction at home.But the crane gear that all needs to assist in construction is with the lifting of front support crossbeam.When the auxiliary beach that crane gear can't arrive the job site or execution conditions are restricted, difficulty of construction is large, valley, urban viaduct, when striding the construction of river, bridge spanning the sea place continuous beam, often need the workman to utilize jack with the supporting traverse lifting, then finish the height of deciding of front support crossbeam by the mode of thereunder filling up cement block or steel plate, but this kind method operation easier large, have drawbacks such as potential safety hazard and fitting operation man-hour be long.
Summary of the invention
The present invention provides a kind of front support crossbeam hoisting system that utilizes hydraulic system the front support crossbeam to be finished lifting in order to overcome the deficiency of above technology.
The present invention overcomes the technical scheme that its technical problem adopts:
This front support crossbeam hoisting system, comprise two pier shaft bearings, vertically be placed on two supporting cylinder and Hydraulic Stations on the pier shaft bearing respectively, described two supporting cylinders are connected to Hydraulic Station, and the piston rod top of described two supporting cylinders is connected to the bottom of front support crossbeam.
In order to guarantee that the support hydraulic pressure cylinder piston rod reaches when the situations such as unexpected outage, weightlessness occur in the safety of stretching out under the operating mode of bearing load, it is motionless that hydraulic cylinder can keep, and also includes hydraulic lock, and described two supporting cylinders are connected in Hydraulic Station through hydraulic lock.
In order further to improve safety, also comprise two auxiliary supporting legs that adopt H shaped steel to make, described two auxiliary supporting legs are installed on respectively on two pier shaft bearings.
The invention has the beneficial effects as follows: first two supporting cylinders vertically are placed into during use on the pier shaft bearing on the bridge pier, provide power by opening Hydraulic Station for supporting cylinder, two supporting cylinders move simultaneously and can and be fixed on the truss frame for connecting at front support crossbeam two ends and the height that the bridge of the nose gives rise to needs with the front support crossbeam, can realize the front support crossbeam is adjusted to horizontal level by the action to single supporting cylinder.Adopt this front support crossbeam hoisting system can realize fast and accurately the lifting of front support crossbeam, and the potential safety hazard of effectively having avoided manually-operated to exist.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure, 1. front support crossbeam 2. connects truss 3. bridge of the noses 4. bridge piers 5. auxiliary supporting leg 6 supporting cylinders 7. pier shaft bearings.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing 1.
This front support crossbeam hoisting system, comprise two pier shaft bearings 7, vertically be placed on two supporting cylinder 6 and Hydraulic Stations on the pier shaft bearing 7 respectively, described two supporting cylinders 6 are connected to Hydraulic Station, and the piston rod top of described two supporting cylinders 6 is connected to the bottom of front support crossbeam 1.First two supporting cylinders 6 vertically are placed into during use on the pier shaft bearing 7 on the bridge pier 4, provide power by opening Hydraulic Station for supporting cylinder 6, two supporting cylinders 6 move simultaneously and can and be fixed on the connection truss 2 at front support crossbeam 1 two ends and the height that the bridge of the nose 3 gives rise to needs with front support crossbeam 1, can realize front support crossbeam 1 is adjusted to horizontal level by the action to single supporting cylinder 6.Adopt this front support crossbeam 1 hoisting system can realize fast and accurately the lifting of front support crossbeam 1, and the potential safety hazard of effectively having avoided manually-operated to exist.
Also include hydraulic lock, described two supporting cylinders 6 are connected in Hydraulic Station through hydraulic lock.After supporting cylinder 6 was with front support crossbeam 1 jack-up, hydraulic lock got final product the locking hydraulic circuit, can guarantee that the piston rod of the supporting cylinder 6 of this moment keeps the relevant position to maintain static, and had improved stability and the safety of lifting.
Also comprise two auxiliary supporting legs 5 that adopt H shaped steel to make, described two auxiliary supporting legs 5 are installed on respectively on two pier shaft bearings 7.When the bad weather such as strong wind occurring or supporting cylinder 6 occurring damages when causing 1 run-off the straight of front support crossbeam, auxiliary supporting leg 5 can support front support crossbeam 1, prevents security incident.
