The present invention installs sensing device 10 (Fig. 1) at the afterbody of vehicle frame, this sensing device is used for: the speed that the feedback cable reel rotates, so that adjust the rotational speed of reel oil motor 7 at any time, make it identical with the gait of march of electronic special type engineering machinery, reach the purpose of emitting in good time or reclaiming cable; When electronic special type engineering machinery falls back backward, it will play navigation, control operating handle automatically, return along original road, not need manual control.
As shown in Figure 7: sensing device 10 has a disc fixed support 45, establish center hole on the fixed support 45, include a spheroid 40 in this center hole in, cable hole is established at the center of this spheroid 40, wear steel cable sleeve pipe 36 in this cable hole, cable 9 can slide in cable sleeve 36, fixed support 45 top and following each is connected and adjusts backing plate 38 and following adjustment backing plate 42 with bolt 44, above the last adjustment backing plate 38 and adjust down backing plate 42 below be that upper strata four sensors 37 of making the braking sensings and lower floor four sensors 43 that turn to sensing are all around all around respectively installed at the center with the center hole of fixed support 45, the top and the bottom of cable sleeve 36 respectively are nested with a circular cone 48 that can touch upper strata sensor and lower floor's sensor.The limited ring 46 that is enclosed within cable sleeve 36 bottoms plays the protection sensor, and 47 is sensor conductor, and 39 and 41 is respectively to go up spherical cap and lower ball base.Each signal of sensor Access Control circuit, control circuit is according to each signal of sensor control reel oil motor and running gear.
Working principle (each label among the figure: 49-stepping controlling mechanism 50-walking chassis 51-crawler belt 52-central authorities traverse platform) of this sensor device is described below in conjunction with Fig. 8 and Fig. 9.
1 adjusts the cable drum speed to overtake the time
When special type engineering machinery to overtake the time, the oil motor of cable drum rotates to clockwise direction, and along with travelling of vehicle, elastic cable paper will freely discharge below reel.If travelling speed is fast, elastic cable paper is tightened up, and at this moment circular cone 48 must touch the back sensor 432 in lower floor's sensor, just back sensor sends signal, control circuit makes the oil motor of cable drum improve rotating speed according to this signal; If travelling speed is slow, elastic cable paper is loosened, and at this moment circular cone 48 can touch the front sensor 431 in lower floor's sensor, and front sensor sends signal, and the oil motor of cable drum reduces rotating speed.
2 adjust the cable drum speed when travelling backward
When special type engineering machinery travelled backward, the oil motor of cable drum was to rotation counterclockwise, and along with travelling of vehicle, elastic cable paper will be recovered on the reel.If travelling speed is fast, elastic cable paper is loosened, and at this moment circular cone 48 must touch front sensor 431, and front sensor sends signal, and the oil motor of electric reel improves rotating speed; If travelling speed is slow, elastic cable paper is tightened up, and at this moment described back sensor 432 must be touched in the surface of elastic cable paper, and back sensor sends signal, and the oil motor of electric reel reduces rotating speed.
3 self-navigations when travelling backward
When special type engineering machinery travelled backward, if vehicle deflection left, circular cone 48 must touch the right sensor 433 in lower floor's sensor, right sensor just sends signal, it is electric that control circuit gets 5C according to this signal, and right lateral is walked oil motor 53 and underspeeded, and special type engineering machinery falls back to the right;
When special type engineering machinery travelled backward, if vehicle deflection to the right, circular cone 48 must touch the left sensor 434 in lower floor's sensor, left side sensor sends signal, it is electric that control circuit gets 6C according to this signal, and left lateral is walked oil motor 54 and underspeeded, and special type engineering machinery falls back left.
4 brakings are adjusted with buffering
When the special type engineering machinery travelling speed is too fast, circular cone 48 will touch the upper strata sensor, and the upper strata sensor just sends signal, and control circuit sends brake signal according to this signal.Turning to of crawler-type traveling chassis travelled, and is by the deceleration of operating handle realization to oil motor, and follows braking to realize, Reduced Speed Now is to realize by the fuel feeding modulating valve that changes oil motor.
The rotating speed of above-mentioned oil motor can realize adjusting balance with speed by the flow of adjusting modulating valve stepping mechanism 49, adjusts frequency with reduction, reaches the optimum state.
See also the structural drawing of the stepping controlling mechanism of adjusting oil motor shown in Figure 10, this controlling mechanism comprises valve body 63, this valve body 63 is serially connected in the oil feed line of oil motor 7, one of the periphery suit of the adjusting nut of its modulating valve is regulated additional gear 59, about the lower end of valve body 63, fix the oil cylinder 56 of two single effects respectively, the top of the piston 57 of each oil cylinder with pin 60 pin joints can unidirectional handsetting gear 59 moving tooth 61.The angle that once back and forth can stir a tooth of described gear rotation of piston.
Its operating principle is: when not supplying hydraulic oil, spring 65 is pushed piston 57 top of oil cylinder 56 to, and moving tooth 61 is regained by oil cylinder 56 compressions, and moving tooth 61 is separated with modulating valve additional gear 59, location status shown in No. 1 cylinder among the figure; When passing through tubing interface 55 to No. 2 oil cylinder 56 fuel feeding, hydraulic oil promotes piston 57 and moves down, after moving tooth 61 surpasses the opening of oil cylinder 56, under the thrust of little spring 62, moving tooth 61 is embedded into the between cog of modulating valve additional gear 59, promotes the angle (as figure in the state of No. 2 cylinder demonstrations) of modulating valve additional gear 59 to a tooth of clockwise direction rotation, and the hydraulic oil path 64 by modulating valve is diminished, be that fuel delivery diminishes, the rotational speed of oil motor 7 descends.After once promoting to finish, oil is rushed down in the upper end of oil cylinder 56, and spring 65 promotes the state (as the state of No. 1 cylinder demonstration among the figure) that piston 57 upwards is returned to beginning.
In like manner, during No. 1 cylinder action, will promote modulating valve additional gear 59 and rotate the angle of a tooth to counter clockwise direction, make the hydraulic oil path 64 by modulating valve become big, i.e. fuel feeding quantitative change is big, and the rotational speed of oil motor 7 improves.
