Technical Field
The invention relates to an assembly portal, in particular to an integrated assembly portal for transverse moving and lifting of a beam plate.
Background
In recent years, it is common to construct new and improved roads by using a support cast-in-place traversing method or a hoisting method to erect beam slabs under special terrain conditions. Although the longitudinal movement and the transverse movement of the beam plate are conventional processes, the side turning and falling accidents of the beam plate occur frequently due to complex construction environment, narrow operation surface, high process control difficulty and the like.
The conventional simple beam plate mounting method comprises the following steps: a plurality of hydraulic jacks are adopted to synchronously and symmetrically jack the beam into the walking plate, an oblique steel support is arranged between the walking plate and the beam plate, and two hand hoists are adopted for transverse movement as power. The following problems can occur in the existing beam slab erection mode: (1) the supporting member between the walking plate and the beam plate is limited by the operation space and the material performance and can not completely meet the specification requirement, and the limiting device at the contact position of the supporting member and the walking plate has insufficient strength and can not resist the impact force generated by the beam plate at the moment of transverse movement starting, so that the inclined strut is in sliding failure, and the beam plate is toppled; (2) the walking plate is dragged through the hand hoist to realize that the stability of the beam plate transversely moving is not enough, the strokes of the two ends are asynchronous, the speed of the chain of the hand hoist pulled by operating personnel at the two ends is inconsistent, the transverse shaking amplitude of the beam plate is too large, and the unreasonable load of the inclined strut is increased.
Disclosure of Invention
The invention aims to solve the technical problems that newly built and improved (expanded) bridge construction projects are limited by terrain conditions, and beam plates cannot be installed by adopting standard equipment such as a crane and a bridge girder erection machine, and a transverse moving method has to be adopted.

The lifting is changed into lifting, the beam plate is always in an upright state under the action of self weight, the action point during transverse movement moves from the bottom of the beam plate to the cross beam of the portal frame, the beam plate is more stable during movement through stable transmission of the walking plate, the hanging rod and the cross beam, the safety risk during transverse movement of the beam plate is effectively reduced, and the working efficiency is doubled compared with that of the traditional process.
The upright posts are supporting structures of the whole device, the cross beam is a bearing structure of a beam plate and is used for installing a walking plate and a jack, the walking plate is connected with the cross beam in a sliding mode to realize transverse movement of the beam plate, and the jack, a hanging rod and a clamp arranged on the hanging rod are lifting structures of the beam plate; when the beam plate transverse moving mechanism is used, the beam plate does not need to be jacked to the walking plate, a supporting structure for fixing the beam plate does not need to be additionally arranged on the walking plate, compared with the prior art, the walking plate is lighter, the temporary supporting structure of the beam plate is eliminated, and the required tension is naturally reduced during transverse moving.
The realization principle of the invention is as follows: erecting an upright post, fixing the upright post, clamping a beam plate on a clamp between two suspension rods, synchronously lifting the suspension rods by two through jacks, synchronously lifting the clamp by the suspension rods, and synchronously lifting the beam plate by the clamp; after the beam plate is lifted and separated from the prefabricated pedestal, the penetrating jack stops acting, the horizontal jack for transverse movement is started, the horizontal jack pushes the walking plate to slide on the cross beam, when the walking plate walks to a designed position, the horizontal jack stops acting, the penetrating jack is started again, the beam plate is lowered until the beam plate is placed on the support, and the lifting and transverse movement of the beam plate are realized; the walking plate and the hanging rod are reset through manually operating the hand hoist, and the next beam plate transportation can be carried out. By applying the device, the jacking is changed into lifting, the beam plate is in a standing state all the time under the action of dead weight, the action point during the transverse movement is more stable during the movement of the beam plate from the beam plate bottom moving portal beam through the stable transmission of the walking plate, the suspension rod and the beam, the safety risk during the transverse movement of the beam plate is effectively reduced, and the working efficiency is doubled compared with the traditional process.
The two through jacks share one oil pump, the oil pump is communicated with an oil inlet pipe and an oil return pipe, one end of the oil inlet pipe is communicated with the oil pump, the other end of the oil inlet pipe is communicated with a three-way shunting type regulating valve, two outlets of the three-way shunting type regulating valve are respectively communicated with the two through jacks through shunt pipes, the shunt pipes of the two through jacks, which are respectively communicated with the three-way shunting type regulating valve, are two pipelines with the same size and specification, one end of the oil return pipe is communicated with the oil pump, the other end of the oil return pipe is communicated with a three-way converging type regulating valve, two inlets of the three-way converging type regulating valve are respectively communicated with the two through jacks through converging pipes, and the converging pipes of the two through jacks, which are communicated with the three-way converging type regulating valve, are two pipelines; the three-way shunting type regulating valve and the three-way converging type regulating valve are arranged between the two through jacks and are fixedly connected with the walking plate.
