Abstract
The utility model relates to a telescopic signal transmission mechanism, which is provided with a signal cable. The telescopic signal transmission mechanism is characterized in that the signal cable comprises a spiral cable and common cables connected to ends of the spiral cable; the spiral cable is arranged at one side, where a piston rod is not arranged, in the piston cylinder; one end of the spiral cable is fixed at the end part of the piston cylinder through a fixing member and penetrates out of the end part of the piston cylinder and is connected with an external electric appliance through the common cable; and the other end of the spiral cable is fixed on the end surface of the piston through a fixing member and is connected with the common cables, and the end of each common cable passes through a piston and the piston rod to be connected with an external electric appliance element, and therefore signal transmission is achieved. According to the utility model, the cost of the telescopic signal transmission mechanism is about 1/10 of that of a cable coiler; and meanwhile, the signal transmission cable is always in an enclosed mechanism, the signal transmission cable is better protected, and the reliability of the signal transmission mechanism is enhanced. The telescopic signal transmission mechanism can be widely applied to a single-stage telescopic arm support type aerial work platform and a single-stage telescopic arm support type elevator.
Description
Technical field
The utility model relates to engineering machinery field, is specifically related to a kind of telescopic signal transport sector of single-stage telescopic boom posture lifting equipment.
Background technology
All be provided with single-stage telescopic boom posture system on single-stage telescopic boom posture weight-lifting equipment or the part high-altitude operation platform.Need be provided with the signal transport sector in this single-stage telescopic boom posture system, signal cable in the sort signal transport sector need can servo-actuated in the expanding-contracting action of single-stage telescopic boom posture system, ensure the reliability of signal transmission simultaneously.
The transport sector of single-stage telescopic boom posture system transmissions signal common mainly is a cable reel at present; The structure of this cable reel of the prior art is: cable reel is fixed in canned paragraph; Cable rope one end is fixed in active segment; When doing fore and aft motion along with active segment relative fixed section, cable coils on reel and loosens.
The problem of said structure is, price is expensive, stretch out cable and be exposed to the external world fully, and not protection, cable has the danger that is damaged in motion process.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art; The purpose of the utility model provides a kind of telescopic signal transport sector of single-stage telescopic boom posture lifting equipment; This new signal transport sector can more effective guard signal cable, has strengthened the reliability of signal transport sector.
The technical scheme that the utility model adopts is: a kind of telescopic signal transport sector, be provided with signal cable, and it is characterized in that: described signal cable is made up of spiral cable and the common cable that is connected its two ends; Described spiral cable places a side of piston-rodless in the piston barrel: an end of this spiral cable is fixed on the piston barrel end with connecting element, and passes this piston barrel end and be connected with extraneous electric elements through common cable; The other end of this spiral cable is fixed on the piston end surface with connecting element, and is connected with described common cable, and the other end of this common cable passes piston, pass piston rod is connected with extraneous electric elements, thereby realizes the transmission of signal.
The structure of described piston barrel, piston, piston rod is: an end and the piston of piston rod are fixed, and piston can be done linear slide in piston barrel, and the other end of piston rod is positioned at the piston barrel outside all the time; Spiral cable places a side of piston-rodless in the piston barrel; One end is fixed on the piston barrel end with connecting element; Be connected with extraneous electric elements through common cable, the other end is fixed on the piston end surface with connecting element, is connected with common cable one end; The common cable other end passes piston, pass piston rod is connected with extraneous electric elements, thereby realizes the transmission of signal; Entire mechanism is a closing means, and common cable is relative and piston rod is static, thereby has realized the effective protection to cable.
When piston slided with respect to piston barrel, spiral cable can elongate or shorten, and the length of spiral cable elongation is slightly larger than piston stroke, and when piston bounced back fully, spiral cable was in the drift state.
Leave cable-through hole on the described piston, described piston rod is a hollow stem, and its spiral external diameter is less than the piston barrel internal dimensions under the spiral cable free state, and the piston barrel inside face is smooth.
The set-up mode of described piston barrel, piston and piston rod is: described piston barrel fixedly installs, described piston and piston rod movement; Also can be that described piston and piston rod are fixed, described piston barrel motion.
Said telescopic signal transport sector can built-in installation on single-stage telescopic boom posture lifting equipment in the utility model, also can external installation on single-stage telescopic boom posture lifting equipment.
The beneficial effect of the utility model is:
The manufacturing cost of the utility model is about 1/10th of cable reel.
The utility model guarantees that signal-transmitting cable is in the closing means all the time, and the better protection signal-transmitting cable has strengthened the reliability of signal transport sector.
The utility model adopts common cable, piston, piston rod, piston barrel, spiral cable to form version, can be widely used in single-stage telescopic boom posture high-altitude operation platform, in the single-stage telescopic boom posture weight-lifting equipment.
Description of drawings
Fig. 1 is the utility model mounting structure scheme drawing.
The specific embodiment
Embodiment 1, and telescopic signal transport sector is with reference to Fig. 1: in single-stage telescopic arm support system; Go up fixed piston tube 2 at its telescopic boom (not accompanying drawing), piston 3 places in the piston barrel 2 after fixing with piston rod 4 one ends; Piston rod 4 other ends are fixed on the basic arm (not accompanying drawing), when telescopic boom (not accompanying drawing) is flexible, drive piston barrel 2 relative and piston 3 slips; Spiral cable 1 is in piston barrel 2 inner elongated or shortenings; Piston rod 4 in-to-in common cables 5 are static with piston rod 4 relatively, thereby the protection of realization signal cable has strengthened the reliability of signal transport sector.
Spiral cable 1 places in piston barrel 2 rodless cavities; The one of which end is fixed on piston barrel 2 ends with connecting element (not accompanying drawing) and is connected with electric elements (not accompanying drawing) through common cable 5; The other end is fixed on the piston 3 with connecting element (not accompanying drawing) and is connected with an end of common cable 5; The other end of common cable 5 passes piston 3, piston rod 4 is connected with extraneous electric elements (not accompanying drawing), thereby realizes the transmission of electric signal.
