Description

A kind of built-in five arm synchronization telescope drag chain devices
Technical field
The present invention relates to the synchronization telescope drag chain device in a kind of aerial lift device (high-altitude operation platform) multistage operating arm, particularly relate to a kind of built-in five arm synchronization telescope drag chain devices.
Background technology
The flexible drag chain device that adopts usually of self-propelled straight-arm aerial lift device jib is transported to hydraulic power, electrical control signal and external power supply etc. in the actuating unit and controller on the jib front-end operations platform, reaches the purpose of people at high-altitude application.Particularly for Synchronized Telescopic boom type aerial lift device.Referring to Fig. 1, existing aerial lift device drag chain device adopts and is built in jib in-to-in installation form, is usually used in three joint arm synchronization telescopes.Its principle of work shows as hydraulic pressure and telescopic oil cylinder is walked around through being fixed in the drag chain conduit entering bonded assembly drag chain on the basic arm in electric soft road; Lead to second telescopic boom bottom; Fixing the electric flexible pipe of hydraulic pressure is transported to the jib front end with it, is connected at last and is communicated with the control of signal and power up and down on the bench board along its two bottom sides.
The major defect of prior art: can only be used for three joint synchronization telescope jibs, can't be applied on the five joint synchronization telescope jibs; Equipment needs together with steel rope, and telescopic oil cylinder and pulley are installed together, and its mounting process is loaded down with trivial details; The inner structure compact in design, mostly its parts are relative motion, easy interference, collision also possibly make towing chain mechanism sustain damage, thereby influence the normal use of equipment.
Summary of the invention
Technical matters to be solved by this invention provides a kind of can using on the five joint synchronization telescope jibs, and mounting process is simple, the built-in five arm synchronization telescope drag chain devices that its parts can not interfere, collide.
In order to solve the problems of the technologies described above; Built-in five arm synchronization telescope drag chain devices provided by the invention comprise basic arm, first jib, second jib, the 3rd jib, the 4th jib and pipeline, and first drag chain is installed in the described basic arm bottom groove; The front end of described first drag chain is fixed on the described basic arm; The curved back of the tail end of described first drag chain volume is connected with inner catheter counterpart on described second jib at a distance from crossing the described first jib tail end, and described inner catheter is fixedly connected on described second jib, and described inner catheter slip cap is contained in the outer catheter; The front end of described outer catheter is fixedly connected on described the 3rd jib; The end of described outer catheter is connected with sliding rack, and described sliding rack can slide on described the 4th jib, and second drag chain is installed in described the 4th jib; The front end of described second drag chain is fixed on described the 4th jib; The tail end of described second drag chain is connected with the end of described inner catheter, and described pipeline passes described first drag chain, described inner catheter and described second drag chain along the afterbody of described basic arm, leads to actuating unit at the head of described the 4th jib.
On described sliding rack, pulley is installed, the tail end of described second drag chain is walked around described pulley and is connected with the end of described inner catheter.
Described inner catheter is fixedly connected on described second jib through first mounting bracket,
The front end of described outer catheter is fastened on described the 3rd jib through second mounting bracket.
Adopt the built-in five arm synchronization telescope drag chain devices of technique scheme, five joint jibs are the synchronization telescope form when operation, lean on telescopic oil cylinder drive related chain carry out.When first jib, the second jib ahead running, drive first drag chain that is connected on second jib and follow motion together, the first drag chain excess length is unsettled in first jib, but the first drag chain management and control, three joint jibs are flexible.Two joint jibs are flexible after another second drag chain management and control, and its principle is identical with article one drag chain.
Compared with prior art, the invention has the advantages that: adopt two drag chain management and control, five joint jib synchronization telescopes; Be built in the jib, effectively protect drag chain to avoid the foreign object collision; Product appearance and productive costs there is positive role.
Description of drawings
Fig. 1 is existing drag chain device scheme drawing.
Fig. 2 is the built-in five arm synchronization telescope drag chain device scheme drawings of the present invention.
Fig. 3 is built-in five arm synchronization telescope drag chain device work scheme drawings.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Referring to Fig. 2; Basic arm 1, first jib 2, second jib 3, the 3rd jib 4 and the 4th jib 5 be suit successively, and first drag chain 6 is installed in basic arm 1 bottom groove, and the front end of first drag chain 6 is fixed on the basic arm 1; The curved back of the tail end of first drag chain 6 volume is connected with inner catheter 8 counterparts on second jib 3 at a distance from crossing first jib, 2 tail ends; First mounting bracket 7 connects the inner catheter 8 and second jib 3, and inner catheter 8 slip caps are contained in the outer catheter 9, and the front end of outer catheter 9 is fixedly connected on the 3rd jib 4 through second mounting bracket 71; The end of outer catheter 9 is connected with sliding rack 10; Sliding rack 10 can slide on the 4th jib 5, and pulley 11 is installed on the sliding rack 10, and second drag chain 61 is installed in the 4th jib 5; The front end of second drag chain 61 is fixed on the 4th jib 5; The tail end of second drag chain 61 is walked around pulley 11 and is connected with the end of inner catheter 8, and pipelines such as oil pipe, cable pass first drag chain 6, inner catheter 8 and second drag chain 61 along the afterbody of basic arm 1, leads to actuating unit at the head of the 4th jib 5.
