Description
Affiliated technical field
The utility model relates to the annex that the car hosit crane arm is used, particularly the transmission spooler of electric signal in the control crane arm telescopic process.
Background technology
In the crane boom telescopic process, the electric signal that has people such as control its superelevation, overload and warning to need, supply the matching used automatic line receiver of crane boom in the market, its structure is directly to drive a single-core line by a clockwork spring to stretch along a slideway, the spooler of this structure, above-mentioned required electric signal can only singlely be controlled, two kinds of signals can not be controlled simultaneously, and this structure makes the contractility of clockwork spring little, the easy clamping stagnation of heart yearn, in order to reach required contractility, have only the lengthening of increasing clockwork spring, make its volume become big.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned technology, to provide a kind of and can transmit two path signal and the good automatic line receiver of result of use.
The technical solution adopted in the utility model is: protecgulum is captiveed joint with bonnet, in adorn a retractor device and be connected with heart yearn, heart yearn twists in the cavity of bonnet, wire hole on bonnet is flexible, described heart yearn is a double wired conductor, two movable contact springs of double wired conductor respectively be fixed on bonnet on two conductive rings contact, and the rotation of can on conductive ring, sliding, be provided with insulated ring between two conductive rings, described retractor device comprises that a pair of gear intermeshes, front axle one end connection gear, the other end and the clockwork spring that is installed in the protecgulum are fixed, rear axle one end connection gear, and the other end is connected with bearing on being fixed on bonnet, double wired conductor is on drum part, and the drum part fixed cover is on rear axle.
Owing to adopt technique scheme, the utility model can transmit two path signal reliably, drive disk assembly is effectively flexible and volume is very little.
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structure cutaway view of the present utility model
Fig. 2 is that A-A among Fig. 1 is to view.
The specific embodiment
As shown in Figure 1, protecgulum 1 is captiveed joint with bonnet 8, in adorn a retractor device and be connected with heart yearn 5, heart yearn 5 twists in the cavity of bonnet 8, the wire hole 7 on bonnet 8 is flexible, heart yearn 5 adopts double wired conductors.
The clockwork spring 11 of a certain-length is installed at protecgulum 1 inner chamber, clockwork spring 11 tightly is coiled in the protecgulum 1, front axle 10 1 ends and clockwork spring 11 are fixing, the other end extends in the bonnet 8, connect a gear 9 by key, gear 9 intermeshes with gear 2, and an end of rear axle 3 is by key connection gear 2, and the other end is connected with the bottom surface of bonnet 8 by bearing 6.Fixed cover drum part 4 on rear axle 3, drum part 4 and rear axle 3 coaxial rotations, and around double wired conductor, the length of double wired conductor is decided according to the control height of crane boom on drum part 4.As shown in Figure 2, one end of double wired conductor is connecting two movable contact springs 12,13, on bonnet 8, fix two conductive rings 14,15, two movable contact springs 12,13 stretching along with rear axle 3 and double wired conductor, on conductive ring 14,15, slide and rotate, be provided with insulated ring 16 between two conductive rings 14,15, insulated ring 16 is gaps of reserving on bonnet 8, also an insulating material circle can be installed in addition.
Described two gears 2,9 adopt the stop-off plastics manufacturing, and it meshes than being: 2.7～4, when the length of clockwork spring 11 is 5 meters, the number of teeth of gear 2 can be made as 56 teeth, and the number of teeth of gear 9 is made as 17 teeth.
For making shell stand the influence of outdoor environment, protecgulum 1 adopts insulating material with bonnet 8, can avoid the shell conduction.
The utility model in actual applications, three anchor posts are welded in hoisting crane basic arm arm head position, control box is connected by attached cable on the fixedly leading-out terminal of double wired conductor and the hoisting crane, and the movable leading-out terminal of double wired conductor is fixed on the anchor strut of hoisting crane epimerite arm arm head.When crane arm is overhanging, the movable leading-out terminal that drives double wired conductor simultaneously outwards stretches, and when crane arm bounced back, double wired conductor was under the effect of self clockwork spring 11 pulling force, bounce back synchronously with crane arm, so just formed a electrical signal transmission system from the hoisting crane basic arm to the epimerite arm.Because two line conductors are arranged, so can transmit two path signal, wherein one the tunnel is used to transmit hoisting crane height limit signal, and another road is used for transmitting reports to the police or other signal.
