Abstract
The utility model relates to an automatic outrigger stretching speed increasing device. An output of a throttle increasing signal acquisition mechanism is connected with an electrical control system. The automatic outrigger stretching speed increasing device is characterized in that the structure of the throttle increasing signal acquisition mechanism is that a valve body of a debarkation multi-way valve controlling an outrigger to stretch is provided with a travel switch, the travel direction of the travel switch is vertical to the axis of a valve core of the debarkation multi-way valve, the valve core of the debarkation multi-way valve is also provided with a cylindrical collision block, a circular groove is cut in the center of the lateral surface of the cylindrical collision block, and when the size of the circular groove is matched with that of an idler wheel at the collision position of the travel switch, the best effect can be obtained; and the fixing mode of the valve body of the debarkation multi-way valve and the travel switch is that the valve body of the debarkation multi-way valve is fixed with a mounting plate and the travel switch is fixed on the mounting plate. The automatic outrigger stretching speed increasing device can accurately realize acquisition of the outrigger stretching signal and has the advantages of low cost and convenient transplantation.
Description
Technical field
The utility model relates to the automatic aggrandizement apparatus of a kind of supporting leg stretching speed.
Background technology
The work of construction machinery and equipment series products the time need be stretched out supporting leg mostly guaranteeing the safe, stable of vehicle operation, but because when stretching out supporting leg, driving engine is in tickover and causes the supporting leg operating time longer.This just requires to design a kind of device that can increase engine throttle when supporting leg is operated automatically.
At present domestic have a spot of vehicle refitting factory to adopt pressure switch to gather throttle to increase signal, and control ECU unit, chassis realizes that the supporting leg speed of stretching out increases function, its shortcoming is the cost height, is easy to generate maloperation and need carries out good coupling with hydraulic efficiency pressure system, has increased the trouble point.
Summary of the invention
The purpose of this utility model provides the automatic aggrandizement apparatus of a kind of supporting leg stretching speed, and this device will be a kind of low cost, the automatic aggrandizement apparatus of supporting leg stretching speed highly reliable, easy for installation.
For addressing the above problem, the technical solution adopted in the utility model is: the automatic aggrandizement apparatus of a kind of supporting leg stretching speed, the output that throttle increases acquisition of signal mechanism is connected with electric control system, it is characterized in that, the structure that described throttle increases acquisition of signal mechanism is as follows: the valve body of the multiway valve of getting off that the control supporting leg is flexible is provided with travel switch, the axis normal of the stroke directions of the trip switch and the multiway valve spool of getting off; One cylindrical collision block is installed on the spool of multiway valve of getting off simultaneously, and this place, cylindrical collision block side cutting has a circular trough.If the roller size at the size of this circular trough and described travel switch bump place coupling then can obtain best effects.
The valve body of the described multiway valve of getting off and the fixed form of travel switch are: be fixed with an adapter plate on the valve body of multiway valve of getting off, described travel switch is fixed on this adapter plate.
Innovative point of the present utility model is: adopt the collection that the device is made up of adapter plate, cylindrical collision block, travel switch can the flexible signal of accurate realization supporting leg, and with low cost, transplant and make things convenient for.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment 1, the automatic aggrandizement apparatus of supporting leg stretching speed, with reference to Fig. 1: on the flexible spool of the multiway valve 4 control supporting legs of getting off a cylindrical collision block 3 is installed, a circular trough is cut in center, cylindrical collision block 3 side, roller 5 size match at circular trough size and travel switch 2 bump places.Make an adapter plate 1 fixed journey system switch 2 in addition, make it good with collision block 3 couplings.Realize that by breaking the flexible handle of control supporting leg off with the fingers and thumb the collision block 3 on the spool moves up and down, thereby trigger travel switch 2, realize acquisition of signal.Control system is sent throttle increase signal after receiving signal automatically, increases the operating speed of driving engine by the engine throttle control module, thereby realizes the quick-expansion of supporting leg.
