Abstract
The invention relates to a tow chain mechanism of a telescopic arm support. The invention comprises the parts of the existing tow chain mechanism such as a tow chain, a bracket, a conduit, an arm support I, an arm support II, an arm support III, and the like; one end of the tow chain is fixed at the right end of the bracket; one end of the conduit is fixed on the arm support III. A guiding rail is arranged on the arm support I; the guiding rail is provided with a sleeve capable of moving along the guiding rail; the other end of the sleeve is fixed on the arm support II; the other end of the tow chain penetrates through the sleeve and is fixed on the conduit; and the other end of the conduit can move in the sleeve. In the invention with the structure, when the arm supports are stretched out, the originally suspended section of the tow chain drops into the sleeve, thus causing the tow chain to be in a supported state all the time. Meanwhile, the sleeve can also support the conduit, and the downwards gravity of the sleeve is pulled by the guiding rail. The structure not only can lower the strength requirement on the tow chain, reduce the cost and eliminate the limit for suspended length, but also can greatly improve the reliability of the operation of the equipment as the tow chain is in a supported state all the time.
Description
Technical field
The present invention relates to the towing chain mechanism on a kind of telescopic arm support.
Background technique
Aerial lift device often need be transported to hydraulic power and electrical control signal in the control box on the actuator of jib end and the hurdle of working by pipeline.For telescopic boom posture aerial lift device, generally adopt towing chain mechanism to solve this type of problem especially.Following Fig. 1 is current main drag chain form.Hydraulic pressure and the electric pipeline mode by flexible pipe is arranged at drag chain 2, through conduit 3 hydraulic power and electric signal is transported to jib III end again, thereby guarantees the connection of signal and power up and down.When jib protracts, jib II and the same moved further of jib III, the conduit 3 that is fixed in jib III drives drag chain 2 along with moving forward, and when jib II protracted to limit position, situation was as shown in Figure 2.As shown in Figure 2, when conduit 3 afterbodys moved forward above jib I head, one section of drag chain 2 just began to lose support, and when conduit 3 reached limit position forward, it is the longest that drag chain 2 is suspended in aerial distance, generally reaches 1/2 of whole jib range.At this moment, the weight that the hydraulic pressure of drag chain and inside and electric pipeline produce needs the intensity of drag chain itself to guarantee, and drag chain hovering length is conditional.The hovering drag chain is because the distortion that gravity causes also is easy to generate the situation of inefficacy.
Summary of the invention
The technical problem that the present invention need solve is: the situation of drag chain hovering often occurs at existing towing chain mechanism, and propose a kind of mechanism that provides support for drag chain.
The technical solution adopted in the present invention: the present invention includes the parts that all have in the existing towing chain mechanisms such as drag chain, bracket, conduit, jib I, jib II, jib III, a right-hand member that is fixed in bracket of drag chain, one of conduit is fixed on the jib III.On the jib I guide rail is installed, guide rail is provided with the sleeve pipe that can move thereon, and the other end of sleeve pipe is fixed on the jib II, and the other end of drag chain is passed sleeve pipe and is fixed on the conduit again, and the other end of conduit can be moved in sleeve pipe.
Beneficial effect of the present invention: the present invention with above structure is when jib stretches out, and originally the drag chain section of hovering all falls into sleeve pipe, drag chain is in all the time is subjected to holding state.Meanwhile, sleeve pipe also has supporting effect to conduit, and the downward gravity of sleeve pipe is drawn by guide rail.This structure not only can reduce the requirement of strength to drag chain itself, reduces cost, and eliminates the restriction of unsettled length, and because drag chain is in all the time and is subjected to holding state, the reliability of equipment work is greatly improved.

Embodiment
See also Fig. 3-Fig. 4, the present invention is on existing telescopic arm support towing chain mechanism basis, guide rail 10 that is fixed on mechanically on the jib I and the sleeve pipe 9 that can on guide rail 10, slide have been increased, stressed and the supporting form of drag chain 2 has been done very big improvement, because when jib II and jib III stretch out forward synchronously, the sleeve pipe 9 that is fixed on jib II equates that with conduit 3 on being fixed on jib III the drag chain section of Fig. 2 Central Plains hovering all falls into sleeve pipe 9 in distance that guide rail 10 moves in the distance that sleeve pipe 9 moves.After having adopted structure of the present invention, the unsettled length of drag chain 2 and the stroke of jib are irrelevant, and drag chain 2 is in all the time and is subjected to holding state, thereby has improved the reliability of equipment work.
