Abstract
The utility model discloses an oil electricity transportation flexible towing chain mechanism for a fire fighting truck. The oil electricity transportation flexible towing chain mechanism comprises arm frame towing chain lower supports, towing chain grooves, towing chain lower supports, nylon supports, a plastics towing chain, and draw bar groove rear supports, wherein the arm support towing chain lower supports of all arms are respectively fixed on arm heads, and the towing chain grooves of all arms are connected to the arm frame towing chain lower supports. The draw-bar groove rear support is fixed at the rear parts of the towing chain grooves. The middle parts of the towing chain grooves are supported by using the nylon supports. Two ends of the plastic towing chain are respectively fixed at the front ends and the rear ends of the upper towing chain groove and the lower towing chain groove. Oil pipes and cables are symmetrically arranged in the towing chain grooves and the plastic towing chains. All towing chain grooves are respectively fixed on all arms of the fire fighting truck through the arm frame towing chain lower supports. The draw-bar groove rear supports are arranged at the rear parts of the towing chain grooves during movement, and nylon pulleys are arranged at the lower parts of the draw-bar groove rear support, thus the rolling friction between the towing chain grooves is ensured, the noise and the bump during movement are reduced; and the oil pipes and the cables are symmetrically arranged in the towing chain grooves, thus the oil electricity transportation function at a highest point on a flexible arm of the fire fighting truck is realized.
Description
Technical field: the utility model relates to a kind of towing chain mechanism, especially a kind of cloud used in fire-fighting oil electricity is carried flexible towing chain mechanism, belongs to fire-fighting equipment field.
Background technology: a kind of drag chain telescoping mechanism of carrying for oil electricity will be installed on fire fighting truck jib, its function be will with jib synchronization telescope. oily electricity is transported to the top of jib.And the lateral space of jib is limited, tubing bending radius is very large again, and domestic a lot of producers all adopt steel pull chain below 50 meters on fire fighting truck, and Heavy Weight, institute take up space large.The vehicle of external producer more than 50 meters mostly adopts the form for sliding motion between dee and dee, and that institute takes up space is large, noise is large when motion, and if on 70 meters high spray fire fighting trucks, adopt traditional method, just cannot realize the conveying of oil electricity.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the utility model provides a kind of used in fire-fighting oil electricity to carry flexible towing chain mechanism.
For achieving the above object, the technical solution adopted in the utility model is: used in fire-fighting oil electricity is carried flexible towing chain mechanism, comprises jib drag chain lower support, dee, drag chain lower support, nylon support, plastics drag chain, pull rod slot rear support.The jib drag chain lower support of each arm is separately fixed on arm head.The dee of each arm is connected in jib drag chain lower support.Pull rod slot rear support is fixed on dee rear portion.Dee middle part is supported with nylon.The two ends of plastics drag chain are separately fixed at the front and back end of upper and lower dee.Being arranged in dee and plastics drag chain of oil pipe and cable symmetry.Each dee is separately fixed on the every joint arm of fire fighting truck by jib drag chain lower support.
On fire fighting truck arm, in drag chain flexible (oil electricity is carried) mechanism, every joint dee is separately fixed on the every joint arm of fire fighting truck by jib drag chain lower support.It drives dee to move by every joint jib is flexible by every joint jib drag chain lower support, and dee drives again drag chain and jib to be synchronized with the movement.When motion, pull rod slot rear support is equipped with at dee rear portion, nylon pulley is equipped with in pull rod slot rear support bottom, ensure between dee to be rolling friction, while reducing noise and motion, jolt, in oil pipe and cable equal symmetrical installation drag chain and dee, this has just realized the oil electricity conveying function of peak on fire fighting truck telescopic arm.

Detailed description of the invention:
As shown in Fig. 1-Fig. 6, used in fire-fighting oil electricity is carried flexible towing chain mechanism, comprises jib drag chain lower support 1, dee 2, drag chain lower support 3, nylon support 5, plastics drag chain 6, pull rod slot rear support 7.The jib drag chain lower support 1 of each arm is separately fixed on arm head.The dee 2 of each arm is connected in jib drag chain lower support 1.Pull rod slot rear support 7 is fixed on dee 2 rear portions.Dee 2 middle parts are supported 5 with nylon and are supported (9 meters of long centres of dee are easily recessed).The two ends of plastics drag chain 6 are separately fixed at the front and back end of upper and lower dee 2.Being arranged in dee 2 and plastics drag chain 6 of oil pipe and cable symmetry.Each dee 2 is separately fixed on the every joint arm of fire fighting truck by jib drag chain lower support 1.All there are framework and peripheral board in outside by whole mechanism outer cover, and overall appearance forms one with jib.
Operation principle: it drives dee to move by every joint jib is flexible by every joint jib drag chain lower support, and dee drives again drag chain and jib to be synchronized with the movement.When motion, pull rod slot rear support is equipped with at dee rear portion., nylon pulley is equipped with in pull rod slot rear support bottom, ensure between dee to be rolling friction, while reducing noise and motion, jolt, in oil pipe and cable equal symmetrical installation drag chain and dee, this has just realized the oil electricity conveying function of peak on fire fighting truck telescopic arm boom..
