Description
Technical field
The utility model relates to a kind of drag chain device, specially refers to the overhead drag chain device on a kind of aerial lift device (high-altitude operation platform) working arm.
Background technology
Aerial lift device often adopts towing chain mechanism that hydraulic power, electrical control signal and welder power etc. are transported in the control box on the actuating unit of jib end and the hurdle of working, particularly for telescopic boom posture aerial lift device through pipeline.Existing towing chain mechanism mainly adopts the mode that is placed on jib one side, and keystone configuration is formed and to be comprised hydraulic pressure and electric pipeline, drag chain, outer catheter, inner catheter, bracket, support, basic arm, first telescopic boom, second telescopic boom.Its principle of work shows as hydraulic pressure and electric pipeline is arranged in drag chain through the mode of flexible pipe, through outer catheter, inner catheter hydraulic power and electric signal is transported to the second telescopic boom end again, thereby guarantees the connection of signal and power up and down.
The major defect of prior art: whole towing chain mechanism places the outside side of jib, and towing chain mechanism is prone to interfere impaired with the lifting steel rope when the lifting machine; Jib also possibly make towing chain mechanism sustain damage with other object generation side collision when doing gyroscopic movement, thereby influences the normal use of equipment.
The utility model content
The utility model technical matters to be solved provides a kind of overhead drag chain device that machine can not sustain damage when doing gyroscopic movement that lifts.
In order to solve the problems of the technologies described above, the overhead drag chain device that the utility model supplies comprises conduit and drag chain, and described conduit and described drag chain are installed in the end face of described basic arm and described telescopic jib.
Described drag chain is in the edge-on laying of the end face of described basic arm.
Described telescopic jib comprises first telescopic boom and second telescopic boom; Described conduit comprises outer catheter and the inner catheter that is sleeved in the described outer catheter; The body of described outer catheter is slidingly mounted on the end face of described basic arm; The front end of described outer catheter is connected on described first telescopic boom, and the front end of described inner catheter is connected on described second telescopic boom, and the other end of described inner catheter is connected with the mobile terminal of described drag chain 5.
Adopt the overhead drag chain device of technique scheme; Drag chain is in the edge-on laying of basic arm end face, and its fixed end is installed on the basic arm, and the mobile terminal is installed in conduit one end; Oil pipe, cable are laid forward along end face from the basic arm afterbody; Get into drag chain from the fixed end of drag chain, pass drag chain and conduit successively, lead to actuating unit at the head of telescopic jib.Whole towing chain mechanism places the end face of jib, and towing chain mechanism is difficult for interfering impaired with the lifting steel rope when the lifting machine; Jib just not can not make towing chain mechanism sustain damage with other object generation side collision when doing gyroscopic movement yet, thus the normal use of the equipment of assurance.
Compared with prior art, the advantage of the utility model is: whole towing chain mechanism places the jib end face, and the drag chain of having eliminated because of causing in jib and exterior object generation side collision or the hoisting process lost efficacy; Simple in structure, dependable performance.
In sum, to be a kind of lifting machine can not sustain damage when doing gyroscopic movement the utility model and simple in structure, the overhead drag chain device of dependable performance.
Description of drawings
Fig. 1 is existing towing chain mechanism scheme drawing;
Fig. 2 is along A-A line cut-away view among Fig. 1;
Fig. 3 is the utility model towing chain mechanism scheme drawing;
Fig. 4 is the birds-eye view of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Referring to Fig. 1 and Fig. 2; Existing towing chain mechanism mainly adopts the mode that is placed on jib one side, and keystone configuration is formed and to be comprised hydraulic pressure and electric pipeline 9, drag chain 5, outer catheter 4, inner catheter 6, bracket 8, support 7, basic arm 1, first telescopic boom 2, second telescopic boom 3.Its principle of work shows as hydraulic pressure and electric pipeline 9 and arranges drag chain 5 in through the mode of flexible pipe, through outer catheter 4, inner catheter 6 hydraulic power and electric signal is transported to second telescopic boom, 3 ends again, thus the connection of signal and power about the assurance.
Referring to Fig. 3 and Fig. 4; Basic arm 1 is provided with first telescopic boom 2 and second telescopic boom 3, and drag chain 5 is in the edge-on laying of the end face of basic arm 1, and the fixed end of drag chain 5 is installed on the basic arm 1; The body of outer catheter 4 is slidingly mounted on the end face of basic arm 1; The front end of outer catheter 4 is connected the head of first telescopic boom 2, and inner catheter 6 is sleeved in the outer catheter 4, and the front end of inner catheter 6 is connected the head of second telescopic boom 3; The other end of inner catheter 6 is connected with the mobile terminal of drag chain 5, inner catheter 6 can be under the drive of second telescopic boom 3 outer catheter 4 slides within along the line.Hydraulic pressure and electric pipeline 9 are laid forward along end face from basic arm 1 afterbody, get into drag chain 5 from the fixed end of drag chain 5, pass drag chain 5 and outer catheter 4, inner catheter 6 successively, lead to actuating unit at the head of second telescopic boom 3.
Whole towing chain mechanism places the end face of jib, and towing chain mechanism is difficult for interfering impaired with the lifting steel rope when the lifting machine; Jib just not can not make towing chain mechanism sustain damage with other object generation side collision when doing gyroscopic movement yet, thus the normal use of the equipment of assurance.
Compared with prior art, the advantage of the utility model is: whole towing chain mechanism places the jib end face, and the drag chain of having eliminated because of causing in jib and exterior object generation side collision or the hoisting process lost efficacy.
