Description
One, technical field
The utility model relates to the elevating fire truck safety guard of (comprising water tower fire truck and Elevating platform fire truck), especially can realize getting-on-off interlocking, gets off to the locking of getting on the bus and gets on the bus to the locking system of getting off.
Two, background technology
Elevating fire truck has been the fire-fighting vehicle of air attack and rescue, jib common name on turntable and turntable is got on the bus, the common name of supporting leg on auxiliary girder and auxiliary girder below turntable is got off, and while expansion for the jib that ensures to get on the bus, the stability of complete machine is provided with 4 supporting legs getting off conventionally.Generally supporting leg comprises horizontal support legs and vertical leg, and the expansion of horizontal support legs, in order to increase supporting leg span, improves complete machine stability, and built on stilts propped by complete machine by stretching out of vertical leg.Also have a kind of situation when only by vertical leg, complete machine being propped and just can be met complete machine stability requirement without horizontal support legs, and can save operation floor space and vehicle manufacturing cost.When the jib that launches while not opening supporting leg for preventing from getting off to get on the bus is unrecovered with the jib of getting on the bus, by the maloperation of the supporting leg withdrawal of getting off, must there is getting-on-off interlocking function by national Specification high lifting kind fire fighting truck, to prevent that maloperation from leading to slide-out accident.Specifically, getting-on-off interlocking should meet following logical relation: after 1. horizontal support legs launches, vertical leg could be stretched out to all firm with ground supports (can not soft leg) and by after complete machine leveling, the jib of getting on the bus just allows expansion of 4 vertical leg; 2. jib just allows supporting leg to regain after regaining, and should first receive vertical leg, rear receipts horizontal support legs; 3. when jib in launch the soft leg of job state time should stop, press force revert key and can only make jib to secure side to recovery; If 4. do not have the horizontal support legs can direct control vertical leg; 5. getting-on-off interlocking should complete automatically.Have quite a few there is no getting-on-off interlocking function with regard to current elevating fire truck, this situation is urgently to be resolved hurrily.
Three, summary of the invention
The purpose of this utility model is to provide a kind of getting-on-off interlocking device of elevating fire truck, improves the security performance of elevating fire truck, meets national standard requirement.
The technical solution adopted in the utility model is: the getting-on-off interlocking device of elevating fire truck comprises position sensor and control circuit,, on the vertical leg of getting off, horizontal support legs and the jib of getting on the bus, multiple position sensors are set respectively, the reception signal of sensor is input to controller, controller output signal control lock-up solenoid valve and indicator lamp, the action of fast Chinese percussion instrument.
Utilize approach switch to obtain supporting leg and stretch out the signal of telecommunication whether launching with withdrawal and jib, have following several: 1. horizontal support legs stretches out and puts in place, 2. horizontal support legs is retracted and is put in place, 3. the stretching out of vertical leg during without horizontal support legs, 4. soft leg signal can replace vertical leg stretch out signal with soft leg signal in the time having horizontal support legs, 5. the modulated flat signal of car load, obtained by obliquity sensor, 6. jib deployment signal, it has been generally acknowledged that it is that jib launches that underarm leaves bracket.
Stretching out and retracting that to detect be that 2 approach switchs are arranged on horizontal fixed supporting leg of the utility model horizontal support legs, and is welded in approach switch tablet on horizontal anomalous movement supporting leg; It is to utilize the gap between horizontal fixed supporting leg and horizontal anomalous movement supporting leg to obtain that the soft leg of vertical leg detects, in the time of vertical leg and ground supports, horizontal anomalous movement supporting leg will lift and makes the approach switch action on horizontal fixed supporting leg, and can learn the whether soft leg of vertical leg; When without horizontal support legs, it is that supporting leg dish upper end below supporting leg installs pallet and drive link and slideway additional that vertical leg is stretched out with the detection method of retracting, drive link lower end is with annulus, annulus is being placed on pallet with location not, in the time that vertical leg is flexible, drive link can be along with moving up and down, drive link upper end is with tablet, and when supporting leg stretches out, tablet moves down the acquisition signal of telecommunication.After having obtained above these signals, just can pass through the control of PLC controller or relay contact control, realize getting-on-off interlocking.
