Abstract
The utility model provides a kind of truck with loading crane antioverloading and tumbles safety device, including derrick car supporting leg, signal processor, on four derrick car supporting legs, it respectively corresponds equipped with support leg pressure sensor I, II, III, IV, in truck with loading crane hoist, the supporting leg of opening bears up heavy arm and hoist weight of object pressure, support leg pressure sensor I, II, III, IV is connected to signal processor respectively, control processor output signal controls the hydraulic buttery valve being set on supporting leg hydraulic control circuit, when derrick car will tumble, tumbling phonetic alarm by the side that conducting wire is connect with signal processor can be in time to truck with loading crane hoist automatic early-warning, avoid generation of tumbling when hoist object, guarantee passenger life and property safety.
Description
Technical field
The utility model is that antioverloading is tumbled safety device, is tumbled safety more particularly to truck with loading crane antioverloading
Device.
Background technique
Unitrain of the truck with loading crane as present social transport is many to use when using hoist function
It is improper, hoist rollover is generated, bigger property loss is generated.Setting derrick car hoist object is tumbled protective device thus, existing
The protection of tumbling of derrick car hoist object is set, majority be using data storage in the processor, then stretched using hoist weight and boom
Integration data alignments out determine that boom stops and working condition, supporting leg ground load size are not directly associated, show
During right truck with loading crane hoist, this protection cannot play timely and effectively prevention and early warning and automatic protection is made
With.
Utility model content
The purpose of the utility model patent is automatic early-warning of tumbling to truck with loading crane hoist object, is realized with Che Qichong
Transport vehicle hoist object is tumbled automatic protection and warning function.
To achieve the above object, the utility model truck with loading crane antioverloading safety device of tumbling provides following technology
Scheme:
Truck with loading crane antioverloading is tumbled safety device, including derrick car supporting leg, further includes:
Signal processor receives and stores the pressure value that each support leg pressure sensor is sent, and sends instruction；
Support leg pressure sensor I, II, III, IV is in parallel to be connect with signal processor by conducting wire, for measuring each supporting leg liquid
The pressure value of compressing cylinder；
Hydraulic buttery valve is arranged on supporting leg hydraulic control circuit, the signal processor and hydraulic buttery valve driving power
Control signal connection；
Side is tumbled phonetic alarm, is connect with signal processor by conducting wire, when the audio alert for being connected to signal processor
Audio alert is carried out when signal.
It is zero that signal processor setting logic described further, which is any one pressure of support leg, separately has a pressure of support leg to become
When near critical point, derrick car will tumble.
There are four derrick car supporting leg described further is set, the support leg pressure sensor I, II, III, IV is set to lifting
On transport vehicle supporting leg, and correspond.
Phonetic alarm tumble as buzzer in the preferably described side.
On four derrick car supporting legs, respectively corresponds equipped with support leg pressure sensor I, II, III, IV, risen with vehicle
When weight transport vehicle hoist, the supporting leg of opening bears up heavy arm and hoist weight of object pressure, support leg pressure sensor I, II,
III, it IV is connected to respectively with signal processor, control processor output signal controls the liquid being set on supporting leg hydraulic control circuit
Pressure electromagnetic valve can avoid hoist object in time to truck with loading crane hoist automatic early-warning when derrick car will tumble
When tumble generation, guarantee passenger life and property safety.
Detailed description of the invention
Fig. 1 is the utility model control principle drawing；
Fig. 2 is the utility model locations of structures figure；
In figure: 1, support leg pressure sensor I；2, support leg pressure sensor II；3, support leg pressure sensor III；4, supporting leg
Pressure sensor IV；5, signal processor；6, hydraulic buttery valve；7, side is tumbled phonetic alarm.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is the preferred embodiment in the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
Fig. 1,2 are please referred to, by four derrick car supporting legs, each supporting leg respectively corresponds support leg pressure sensor I 1, branch
Leg pressure sensor II 2, support leg pressure sensor III 3, support leg pressure sensor IV 4 are beaten in truck with loading crane hoist
The derrick car supporting leg opened bears crane arm and hoist weight of object pressure, the supporting leg being correspondingly arranged on derrick car supporting leg
Pressure sensor I 1, support leg pressure sensor II 2, support leg pressure sensor III 3, support leg pressure sensor IV 4 are in parallel by leading
Line is connected with signal processor 5, and signal processor 5 is connect with 6 driving power of hydraulic buttery valve control signal, signal processor
5 output signals control derrick car hoist, operate hydraulic buttery valve 6, realize that hydraulic buttery valve 6 is hydraulic to oil cylinder hydraulic oil control
System, synchronous signal processor 5 and side phonetic alarm 7 of tumbling are connect by conducting wire, and 5 trigger condition of signal processor is to inclination
Phonetic alarm 7 is turned over to signal to alarm；When normal hoist operation, four derrick car pressure of support leg are both greater than 500KN, lifting
By 6 normal control of hydraulic buttery valve, wherein suspension arm hydraulic oil cylinder is run for operation；When hoist object, which is tumbled, to be occurred, supporting leg pressure
Force snesor I 1, support leg pressure sensor II 2, support leg pressure sensor III 3, the two pieces in support leg pressure sensor IV 4 do not have
Pressure value, hoist object tumble generation condition first is that, a pressure of support leg is zero, separately have a pressure of support leg rapidly to zero approach
When crossing into, derrick car will tumble；Support leg pressure sensor I 1, support leg pressure sensor II 2, pressure of support leg are passed thus
The signal processor 5 that sensor III 3, support leg pressure sensor IV 4 are connected, setting logic be any one is zero, separately have one to
When zero approach critical point, signal processor 5 connects the control of hydraulic buttery valve 6 immediately and disconnects control, and hydraulic cylinder fuel cut-off is simultaneously
Locking changed course operation, protection hoist object occur side because operation is uncomfortable and tumble.
By adopting the above-described technical solution, hoist object can be avoided in time to truck with loading crane hoist automatic early-warning
When tumble generation, guarantee passenger life and property safety.
