Abstract
The invention relates to a pai-shaped assembly tooling which comprises a portal frame and an electric welding machine, and a hydraulic clamping device is installed on the portal frame. The hydraulic clamping device comprises a hydraulic power unit, a hydraulic control system and a clamping mechanism. The clamping mechanism comprises hydraulic cylinders fixed on supports and press plates connected with pistons, and the hydraulic cylinders on the left support and the hydraulic cylinders on the right support are mutually symmetrical. The pistons and the press plates are connected together, each support is provided with two hydraulic cylinders, and the two pistons are connected through the press plates. A travelling device comprising travelling cross beams and a driving mechanism is installed on the bottom parts of the supports, both ends of each travelling cross beam are hinged with a guiding device, and the guiding device on the left travelling cross beam is symmetrical to the guiding device on the right travelling cross beam. Because webs and clapboards are mechanically fixed, the working efficiency is increased, and the working strength is reduced. The distance between the press plates are adjusted according to the size of box beams, and the requirement of processing various box beams can be satisfied.
Description
Technical field
The present invention relates to the assembling and positioning device on the crane, particularly π ellbeam group is to frock.
Background technology
At present, girder web on the crane and dividing plate assembling and positioning welder preface as shown in Figure 3, adopt the auxiliary crowbar of π type folder to guarantee the fit-up gap of web and dividing plate substantially, and this kind frock needs 2～3 people to operate simultaneously just and can finish in the web assembly process; During assembling, earlier the π type is folded up on web, make web be positioned at the centre of π type folder, one people or two people are responsible for adjusting with crowbar the gap of web and dividing plate, an other people is responsible for positioning weldering with arc welder, and along with moving of rigging position, otherwise welding cable is started building to adorn and dragged to offset to guarantee clamped position and welding scope.This kind frock, simple in structure, easy to make, use easily, but need according to the box-girder sectional dimension, make corresponding π clevis and satisfy the assembling needs, the work limitation rate is lower, and working strength is bigger.
Summary of the invention
The problem that the present invention solves provides a kind of high efficiency, can process various box-girders π ellbeam group to frock.Technical scheme of the present invention is to finish like this, and π ellbeam group includes portal frame, electric welding machine to frock, it is characterized in that: hydraulic clamp is installed on the portal frame.Described hydraulic clamp includes hydraulic power unit, hydraulic control system, hold-down mechanism.Described hold-down mechanism is by being fixed on the hydraulic cylinder on the support and forming with the pressing plate that piston links together, and hydraulic cylinder and the hydraulic cylinder on the right support on the left socle are symmetrical.Piston and pressing plate are fixed together.Each support is provided with two hydraulic cylinders, and two pistons link together by pressing plate.Described frame bottom is equipped with the running gear of walking crossbeam and driving mechanism composition.Walking crossbeam two ends are hinged with guider, and it is symmetrical that left lateral is walked the guider that guider on the crossbeam and right lateral walk on the crossbeam.Guide link one end of described guider is hinged with the walking crossbeam, and the guide link other end is fixed with directive wheel, and the hinged place is provided with hold down gag.Described hold down gag is made up of bolts and nuts.
Technique effect of the present invention is: because of fixing web, dividing plate by mechanical means, so improved operating efficiency, reduced working strength; Regulate distance between pressing plate according to the size of case beam, can satisfy the needs of the various case beams of processing.
