Abstract
The invention relates to a split type girder moving crane. The split type girder moving crane comprises a left crane frame and a right crane frame, wherein the tops of the left crane frame and the right crane frame are provided with winding engines, each winding engine is provided with a fixed pulley group, each fixed pulley group is connected with a movable pulley group, and each movable pulley group is connected with a suspension girder shoulder pole; and the bottoms of the left crane frame and the right crane frame are provided with running mechanisms. During working, a bridge component is firstly fixed on the suspension girder shoulder pole through a hanger, then the winding engines on the left crane frame and the right crane frame are started at the same time after the bridge component is anchored so that the bridge component is raised to an appointed height, then the running mechanisms are started to drive the left crane frame and the right crane frame to move front and back along rails so that the split type girder moving crane moves to an appointed position, then the winding engines are started, and the bridge component is placed at a specific position for installation.
Description
Technical field
The invention belongs to bridge weight-lifting equipment technical field, specifically relate to a kind of split type beam hoisting crane that moves that is applicable to bridge construction.
Background technology
Along with the needs of China economy suggestion, the developing rapidly of China Expressway, bridge construction is also more and more, and highway bridging machine, as the large special equipment in construction, has become indispensable key equipment in bridge on highway construction.In the process of bridge erection, need to beam slab parts be winched to assigned address by hoisting crane installs, but hoisting crane is all conjoined structure now, above hoisting crane, adopt crossbeam to connect, cause the width of hoisting crane not change according to site environment, seriously limited the lifting scope of hoisting crane.
Summary of the invention
The present invention has solved the existing above-mentioned technical matters of existing Bridge Erector, and the split type beam hoisting crane that moves is provided, and by hanging beam shoulder pole is set, has saved the middle connecting cross beam of hoisting crane, makes hoisting crane not limited by crossbeam; During lifting, only need according to bridge parts, lay the track of respective width, can realize the lifting of bridge parts, increase split type lifting scope of moving beam hoisting crane; And due to the minimizing of connecting cross beam, the split type beam hoisting crane overall weight of moving is significantly reduced, saved enterprise's productive costs.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: the split type beam hoisting crane that moves, comprise left crane frame and right crane frame, described left crane frame and right crane frame top arrange winch, fixed pulley group is set on described winch, described fixed pulley group is connected with running block, and described running block is connected with hanging beam shoulder pole.
As preferably, described left crane frame and from right to left heavy-duty machine bottom of frame arrange traveling gear, in order to control the split type beam hoisting crane that moves, along track, seesaw.
As preferably, on described hanging beam shoulder pole, shoulder pole counterweight is set, for balance hanging beam shoulder pole.
As preferably, on described hanging beam shoulder pole, suspender is set, described suspender is in order to anchorage bridge parts.
The beneficial effect that the present invention has: by hanging beam shoulder pole is set, saved the middle connecting cross beam of hoisting crane, made hoisting crane not limited by crossbeam; During lifting, only need according to bridge parts, lay the track of respective width, can realize the lifting of bridge parts, increase split type lifting scope of moving beam hoisting crane; And due to the minimizing of connecting cross beam, the split type beam hoisting crane overall weight of moving is significantly reduced, saved enterprise's productive costs.Therefore the present invention has the features such as simple in structure, reasonable in design.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is lateral plan of the present invention.
In figure: 1, winch; 2, running block; 3, fixed pulley group; 4, hanging beam shoulder pole; 5, suspender; 6, right crane frame; 7, shoulder pole counterweight; 8, traveling gear; 9, bridge parts; 10, left crane frame; 11, track.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: the split type beam hoisting crane that moves, as depicted in figs. 1 and 2, comprise left crane frame and right crane frame, described left crane frame and right crane frame top arrange winch, fixed pulley group is set on described winch, described fixed pulley group is connected with running block, and described running block is connected with hanging beam shoulder pole; Described left crane frame and from right to left heavy-duty machine bottom of frame arrange traveling gear, in order to control the split type beam hoisting crane orbital motion that moves; On described hanging beam shoulder pole, shoulder pole counterweight is set, for balance hanging beam shoulder pole; On described hanging beam shoulder pole, suspender is set.
During work, bridge parts is first fixed on hanging beam shoulder pole by suspender, after bridge parts anchoring, then start the winch on left crane frame and right crane frame simultaneously, make bridge parts rise to specified altitude assignment, then start traveling gear, drive left crane frame and right crane frame to seesaw along track, make the split type beam hoisting crane that moves move to assigned address, and then start winch, bridge parts is placed on to assigned address and installs; The split type beam hoisting crane that moves has saved the middle connecting cross beam of hoisting crane, makes hoisting crane not limited by crossbeam; During lifting, only need according to bridge parts, lay the track of respective width, can realize the lifting of bridge parts, increase split type lifting scope of moving beam hoisting crane; And due to the minimizing of connecting cross beam, the split type beam hoisting crane overall weight of moving is significantly reduced, saved enterprise's productive costs.
Finally, it should be pointed out that above embodiment is only the more representational example of the present invention.Obviously, the invention is not restricted to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all should think and belong to protection scope of the present invention.
