The technical scheme includes that the dual-gantry crane hydraulic welding device for box girders comprises a gantry and a running end beam, a hydraulic pump platform is arranged on a gantry cross beam which is provided with hydraulic cylinder supports, top hydraulic cylinders are mounted on the supports correspondingly, side hydraulic cylinder supports are mounted on vertical posts of the gantry, horizontal hydraulic cylinders are mounted on the side hydraulic cylinder supports correspondingly, pressing rod mechanisms are mounted on extension walls of the horizontal hydraulic cylinders, two gantry vertical posts are respectively welded on the running end beam, the running end beam is provided with running wheels of a driving device, and a motor and a speed reducer are mounted on the running end beam.

Description

A kind of pair of gantry box beam hydraulic pressure welder
Technical field:
The utility model relates to a kind of pair of gantry box beam hydraulic pressure welder, is specially adapted to the box beam height at 1900mm, width at 2600mm with interior welding.
Background technology:
When existing girder excessive height, web is erect too high, the assembling difficulty, the general employing is placed on web on the platform, sole bar angle draws earlier on the girder web, the position line of inclined to one side steel and girder diaphragm plate, press the line weldering with sole bar angle and inclined to one side steel, tack-weld girder diaphragm plate is located in assembling then, assembling tack welding girder upper cover plate, lower cover after assembling, begins to weld all weld seams in box-girder, in order to make girder web and girder diaphragm plate by tight, the general using web is conducted oneself with dignity and heavy top traditionally, sledgehammer, manual chain block, jack, clumsy instrument such as crowbar is finished, and its shortcoming is that labour intensity is big, production efficiency is low.
Summary of the invention:
Task of the present utility model provide a kind ofly improve the quality of products, production efficiency height, a kind of pair of gantry box beam hydraulic pressure welder reducing labor intensity.Task of the present utility model is finished like this, a kind of pair of gantry box beam hydraulic pressure welder, it comprises portal frame, the walking end carriage, it is characterized in that: be placed on the hydraulic pump platform on the portal frame crossbeam, the hydraulic cylinder bearing is housed on the portal frame crossbeam, correspondence is equipped with the top hydraulic cylinder on its bearing, sidepiece hydraulic cylinder bearing is housed on gantry pillar, correspondence is equipped with horizontal hydraulic cylinder on it, on the flexible wall of hydraulic cylinder pressure lever mechanism is housed, two gantry pillars are welded on respectively on the walking end carriage, on the walking end carriage drive unit running wheel are housed, and motor and speed reducer is installed on the walking end carriage.Be rigidly connected between gantry pillar, portal frame crossbeam, walking end carriage and each parts of hydraulic pump platform.The drive unit running wheel is the track travel that is covered with along on the ground, both sides of jig.The utlity model has following effect: adopt the hydraulic pressure location, improve welding quality, greatly reduce the web wave degree, improved production efficiency, reduced labour intensity.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Fig. 2 is the side view of Fig. 1.Drawing explanation: 1, motor 2, reductor 3, horizontal hydraulic cylinder 4, pressure lever mechanism 5, gantry pillar 6, sidepiece hydraulic cylinder bearing 7, top hydraulic cylinder bearing 8, top hydraulic cylinder 9, hydraulic pump platform 10, portal frame crossbeam 11, walking end carriage 12, running wheel 13, jig 14, beam diaphragm plate 15, girder web 16, girder upper cover plate 17, track
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, gantry pillar 5, portal frame crossbeam 10, be rigidly connected between walking end carriage 11 and hydraulic pump platform 9 each parts, in order to bear moment of flexure and the shearing that hydraulic cylinder produces, hydraulic pump platform 9 is placed on portal frame crossbeam 10 tops, for hydraulic cylinder provides pressure oil, 4 top hydraulic cylinder bearings 7 are housed on the portal frame crossbeam, correspondence is equipped with top hydraulic cylinder 8 on its bearing, can laterally move along portal frame crossbeam lower flange, on the flexible wall of hydraulic cylinder pressure lever mechanism 4 is housed, from the girder top girder web 15 is exerted pressure, girder web and girder diaphragm plate 14 are closed up by tight, 8 sidepiece hydraulic cylinder bearings 6 are housed on gantry pillar 5, the corresponding horizontal hydraulic cylinder 3 of installing on it, can move up and down along gantry pillar, on the flexible wall of hydraulic cylinder pressure lever mechanism 4 is housed, in the horizontal direction girder upper cover plate 16 and girder web are exerted pressure, two gantry pillars 5 are welded on respectively on the walking end carriage 11, on the walking end carriage drive unit running wheel 12 is installed, motor 1 and reductor 2 are installed on the walking end carriage, whole device can vertically come and go along the track on the jig 17 and move, there is track 17 on upper berth, ground, both sides at jig 13, starting motor 1 can make whole portal frame vertically come and go mobile along body frame, top hydraulic cylinder 8 can be along portal frame crossbeam move left and right, horizontal hydraulic cylinder 3 can move up and down along gantry pillar, adjust pressure lever mechanism 4 positions according to need of work, start motor 1 during work whole portal frame is moved to the girder center, work is carried out to two ends by the girder span centre.In order to make girder plate 15 and girder diaphragm plate 14 by tight, adjust the lateral attitude of top hydraulic cylinder 8 as required earlier, starting top hydraulic cylinder 8 drive pressure lever mechanism 4 then is pressed on the girder web 15, make girder web and girder diaphragm plate by tight, location welding when the operator observes fit-up gap and position and meets the requirements in the box girder is adopted with quadrat method to make girder upper cover plate 16 and girder web 15 execute the location welding by tight.Various travelling mechanisms, action of hydraulic mechanism is finished by manually-operated platform button.
