Description
Technical field
The utility model relates to the towing chain mechanism of a kind of hydraulic tubing and control cable, is specifically related to the towing chain mechanism that a kind of band props up overfill protection, is a kind of towing chain mechanism of telescopic boom posture aerial lift device, and drag chain itself is had the support protective effect.
Background technology
At present, the telescopic boom posture aerial lift device of prior art generally adopts towing chain mechanism to realize the conveying of getting on or off the bus of hydraulic tubing and control cable.In the drag chain motion process, can produce vacant state, owing to cause distortion under the effect of in-to-in hydraulic tubing and cable gravity, be out of shape the failure conditions that causes when unsettled, following patent is arranged for solving:
Its technical scheme of a kind of sleeve type towing chain mechanism (ZL 200820052092.8) is: comprise 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 arm I guide rail is installed, guide rail is provided with the sleeve pipe that can move above that, 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.Though this invention has solved the Problem of Failure that distortion caused when drag chain was unsettled, produced wear problem again simultaneously, drag chain will slide in sleeve pipe, is easy to produce wearing and tearing, causes inefficacy; And its part is more, complex structure, and cost is high.
Summary of the invention
The purpose of the utility model provides the towing chain mechanism that a kind of band props up overfill protection, and the scheme of the utility model adopts roll mode, can avoid drag chain skimming wear and simple in structure, and cost is lower.
The technical scheme that the utility model adopted is: a kind of band props up the towing chain mechanism of overfill protection, and this towing chain mechanism is arranged on the telescopic arm support, and an end of drag chain is fixed on the right-hand member of bracket; The other end and conduit left end are fixed; The right-hand member of conduit is fixed on the telescopic boom II, it is characterized in that, also is provided with a supporting mechanism; This supporting mechanism is by bracing frame, and be separately positioned on this above bracing frame, the roller that is arranged on below this bracing frame forms; One end of this bracing frame is fixed on the telescopic boom I, and the other end is supported on above the drag chain through the roller of self, and hold through the support wheel that is fixed on the basic arm centre; Be arranged on this roller above bracing frame and support this drag chain above bracing frame.
In the prioritization scheme of the utility model, also be provided with conductor bracing, this conductor bracing is fixed on telescopic boom I end and holds conduit.
In other words, the utility model comprises drag chain, bracket, conduit, conductor bracing, basic arm, telescopic boom I, telescopic boom II, supporting mechanism etc., and supporting mechanism is by bracing frame, bearing pin, and roller is formed, and roller is connected with bracing frame through bearing pin.The roller of supporting mechanism divides two groups, and one group is positioned at the bracing frame bottom, is used for this motion on drag chain of supporting mechanism, and another group is positioned at the top of bracing frame, is used to support the motion of its top towing chain mechanism.Be positioned at 1 of the number of rollers of bracing frame bottom; The number of rollers that is positioned at bracing frame top is decided (for example, adopting 2-4) according to the length needs of drag chain.One end of bracing frame is fixed on the telescopic boom I, and the other end is supported on the drag chain by roller, and the centre is held by the support wheel that is fixed on the basic arm.Roller has race, and race form and drag chain size are complementary, and guarantees the rolling that roller is can be on drag chain good, has certain directional tagging again.
The beneficial effect of the utility model: to any one state of stretching process entirely, the overhanging portion of drag chain is all supported by supporting mechanism jib full reduced.
The supporting construction of the utility model is made simple, not only can reduce the rigidity requirement to drag chain, and cost-cutting is eliminated the restriction of the unsettled length of drag chain to aerial lift device, and the hanging part of drag chain is in all the time and receives holding state.
The drag chain of the utility model contact surface in motion process is a friction of rolling, has avoided the wearing and tearing of sliding process, improves the reliability and the service life of equipment work greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model telescopic arm support towing chain mechanism jib when full reduced;
Structural representation when Fig. 2 stretches for the utility model telescopic arm support towing chain mechanism jib entirely;
Among the figure: basic arm 1, telescopic boom I 2, telescopic boom II 3, conduit 4, conductor bracing 5, bracing frame 6, support wheel 7, drag chain 8, bracket 9, bearing pin 10, roller 11.
The specific embodiment
On telescopic arm support, an end of drag chain 8 is fixed on the right-hand member of bracket 9, and the other end and conduit 4 left ends are fixed, and the right-hand member of conduit 4 is fixed on the telescopic boom II3, and conductor bracing 5 is fixed on telescopic boom I2 end and holds conduit 4; Supporting mechanism is by bracing frame 6, bearing pin 10, and roller 11 is formed, and an end of bracing frame 6 is fixed on the telescopic boom I 2, and the other end is supported on above the drag chain 8 through the roller 11 of self, middlely holds through the support wheel 7 that is fixed on the basic arm 1.When jib was full reduced, the end that conduit 4 dangles among Fig. 1 was supported by the roller 11 on bracing frame 6 tops; When telescopic boom I2 and telescopic boom II3 stretched out forward synchronously, the bracing frame 6 that is fixed on telescopic boom I2 also was synchronized with the movement with the conduit 4 that is fixed on the telescopic boom II3, and this moment, the roller of bracing frame 6 bottoms rolled on drag chain 8; The unsettled part of drag chain 8 is supported by the roller 11 on bracing frame 6 tops among Fig. 2.So promptly prevent the unsettled sagging of drag chain, also prevented the wearing and tearing of drag chain in motion process, greatly improved the reliability and the service life of equipment work.
