Abstract
The invention discloses an automatic-locating continuous pushing device for large box beams. According to the technical scheme, a plurality of sets of wedge-shaped counter force bases are symmetrically and fixedly installed on the inner side and the outer side of a double-track sliding way respectively in the pushing direction at equal intervals and with the same section, locating clamping grooves are symmetrically and fixedly formed in the lower portions of a pushing support base and meshed with the wedge-shaped counter force bases respectively, jacks are installed inside the pushing support base in a sleeved mode, the front ends of ejection rods of the jacks are fixedly connected with the rear ends of buffering ejection rods through flange plates respectively, and the front ends of the buffering ejection rods are fixedly connected with the box beams respectively. The device overcomes the shortcomings of an existing device used for pushing construction, the positions of the counter force bases do not need to be replaced continuously or the ejection rods do not need to be added or reduced continuously, continuous pushing operation can be carried out, the pushing speed is increased greatly, automatic locating of a pushing system is achieved, the occupation time of hoisting equipment is shortened, the construction cost is saved, and the potential safety hazards on the site are reduced.
Description
Technical field
The present invention relates to a kind of large-size box beam thrustor, specifically a kind of large-size box beam can be located successively incremeantal launching method device automatically, belongs to road and bridge the realm of building construction.
Background technology
Develop rapidly along with high-speed railway and expressway construction, the existing operating line of leap how building a bridge has safely and fast become that scientific research personnel explores and the common objective of research, cross at present the special obstacle things such as existing railway, highway, mountain valley, mainly to adopt cantilever or the concrete beam of turning, but because cantilever or the concrete beam of turning are had relatively high expectations to construction condition, for job site condition difficulty, the leap special obstacle thing object of construction production that higher grade of security risk, utilizing incremental launching construction is a kind of construction technology more safely and efficiently.
Incremental launching construction is to apply horizontal thrust by jack pair body beam, by slideway or slide block by body beam piecemeal or multistage integral body pushing tow forward, the key of incremental launching construction is under certain pushing tow dynamic action, and body beam can move forward with less friction factor on runner device.Current Longspan Bridge incremental launching construction, mainly increase temporary rest pier and establish forwardly from anchor and draw at span centre, take multi-point pushing mode to carry out operation, multi-point pushing construction requires high for construction condition, the incremental launching device needing is many, construction cost is higher, particularly single-point incremental launching construction is generally taked in the body beam pushing tow operation under complex environment, normally on top pushing platform, establish slipway beam, counter-force seat and slipway beam are fixed, at body beam afterbody, pushing tow bracket is installed, before counter-force seat, continuous jack is installed, by continuous jack, puted forth effort after pushing tow on bracket body beam jacking forward by the pushing reaction of counter-force seat, complete continuous jack oil return after a jack-in process, changing counter-force seat puts, cycling.The number of times of putting in order to reduce continuous replacing counter-force seat, can oil return after continuous jack completes jack-in process, takes to add before continuous jack the distance that push rod increases jacking.Due to counter-force seat and push rod weight larger, when changing counter-force seat putting or increase and dismantle push rod on top pushing platform, must adopt crane lifting, artificial cooperation, but scene often occurs, because of counter-force seat latch and the distortion of push rod connecting bolt, causing scene to dismantle, seriously restricted on-the-spot pushing tow work efficiency, waste time and energy, and it is long to take the hanging device cycle, increases considerably construction cost.
Summary of the invention
The object of the invention is in order to overcome the defect that equipment therefor exists in body beam incremental launching construction at present, improve body beam pushing tow work efficiency, save construction cost, reduce hanging device holding time, reduce security risk, and disclose a kind of large-size box beam, can automatically locate successively incremeantal launching method device.
The present invention is achieved by the following technical solutions;
According to jack top Cheng Changdu, inside and outside twin rail runway, both sides are respectively along some groups of wedge shape counter-force seats of the pushing tow direction symmetrical fixed installation in equidistant same cross section, in pushing tow bracket bottom, symmetry fixedly mounts locating groove respectively, locating groove respectively with the interlock of wedge shape counter-force seat, jack is set in pushing tow bracket, mandril of lifting jack front end is fixedly connected with buffering push rod rear end by flange respectively, and buffering push rod front end is fixedly connected with body beam respectively.
The present invention has overcome the defect that current incremental launching construction equipment therefor exists, without continuous replacing counter-force seat, put or add and subtract push rod, can be continuously continually carry out pushing tow operation, increased substantially pushing tow speed, and the automatic location of having realized pushing tow system, reduce the holding time of hanging device, saved construction cost, reduced on-the-spot potential safety hazard.
Accompanying drawing explanation
Accompanying drawing 1 is main TV structure schematic diagram of the present invention.
Accompanying drawing 2 is plan structure schematic diagram of the present invention.
Description of reference numerals is as follows: twin rail runway 1, wedge shape counter-force seat 2, locating groove 3, pushing tow bracket 4, jack 5, flange 6, buffering push rod 7, body beam 8.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is done to more detailed description;
According to jack top Cheng Changdu, in the inside and outside both sides of twin rail runway (1), along the equidistant same cross section of pushing tow direction symmetry, fixedly mount three groups of wedge shape counter-force seats (2) respectively, in pushing tow bracket (4) bottom, symmetry fixedly mounts locating groove (3) respectively, locating groove (3) respectively with wedge shape counter-force seat (2) interlock, jack (5) is set in pushing tow bracket (4), jack (5) push rod front end is fixedly connected with buffering push rod (7) rear end by flange (6) respectively, and buffering push rod (7) front end is fixedly connected with body beam (8) respectively.
Utilize the present invention when construction operation, first the body beam for the treatment of pushing tow is placed on twin rail runway, on twin rail runway, according to top journey distance, enough many groups wedge shape counter-force seats are set, the present invention is installed to relevant position simultaneously, guarantee that locating groove and the interlock of wedge shape counter-force seat buckle, utilize same hydraulic power unit to control two jack, start jack hydraulic gauge tap, when jack is by body beam forward after top journey of pushing tow, jack oil return, because jack front end is fixedly connected with body beam, so jack front end can not move, utilize the towing tension of jack oil return to drive jack rear end and pushing tow bracket integral body to move forward, and while arriving next group wedge shape counter-force seat by wedge shape counter-force seat and locating groove interlock, thereby circulation pushing tow body beam, realize automatic continuous jacking.
