Abstract
The utility model relates to an electrical control circuit of an electronic hydraulic transmission box, which is characterized in that two time delay relays are connected in series at the signal input terminal of a speed control relay and direction control relay group of the electrical control circuit. The electrical control circuit has the beneficial effects that the electrical control circuit can stop high-grade starting of the hydraulic electronic transmission box, thereby facilitating the buffering of a hydraulic clutch, and avoiding the stall and the slipping of the hydraulic clutch, which accelerate damage of components of the hydraulic clutch and the transmission box.
Description
Technical field
The utility model belongs to the control system of automatically controlled hydraulic transmission box, relates in particular to a kind ofly to be applicable to that automatic, the manual automatically controlled hydraulic transmission box electrical equipment control of loader, shipping container front loop wheel machine is a circuit.
Background technique
At present, the loader of harbour service, shipping container front loop wheel machine, it is at the speed control handle of former gearbox and automatical control system and the input signal end of direction Joystick to hang the automatically controlled hydraulic transmission box electrical apparatus control circuit of the clark-15.5HR36432 that hangs adapted in DRD450-60S5K shipping container front as the Ka Erma front, 5 relays of series parallel connection, realize lever operated relay, control electromagnetic valve realizes the function of speed governing and change direction again.The shortcoming that control circuit exists is: because speed handle and direction Joystick distance are very near, the operation driver often occurs forgetting gear shift and in the misoperation of top grade starting, causes fluid clutch stall to skid during operation, quickens its component and gearbox and damages.The shortcoming of said structure all can occur at automatic, manual automatically controlled hydraulic transmission box electrical apparatus control circuit.Because the demand of lifting operation, those skilled in the art demand urgently automatically controlled hydraulic transmission box electrical apparatus control circuit is improved.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and the automatically controlled hydraulic transmission box electrical apparatus control circuit after a kind of the improvement is provided, and can prevent the high-grade starting of fluid power electrically controlled gearbox, obtains buffering in order to fluid clutch.Not only keep its original function characteristic, and reliability is stronger, has prolonged the working life of gearbox.
The utility model for achieving the above object, by the following technical solutions: a kind of automatically controlled hydraulic transmission box electrical apparatus control circuit is characterized in that: at the speed controlling relay of electrical apparatus control circuit and two time delay relays of input signal end series connection of direction control relay group.
The beneficial effects of the utility model are: can prevent the high-grade starting of fluid power electrically controlled gearbox, obtain buffering in order to fluid clutch, avoid causing fluid clutch stall to skid, quicken its component and gearbox and damage.
Description of drawings
Fig. 1 is the utility model working principle connection diagram.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in the figure, a kind of automatically controlled hydraulic transmission box electrical apparatus control circuit is at two time delay relays of signal input part series connection of original control circuit speed controlling relay and direction control relay group.Described time delay relay Placement is: the first via, seal in neutral relay, time delay relay and third gear relay and second gear relay by speed handle electrical signal, third gear relay and second gear relay are in parallel, be connected with other relays, wherein No. 1 relay is that Normally closed type connects, and all the other all are connection open in usual; Secondary route advances, reverse direction Joystick electrical signal seals in and advances and the backward gear relay, and its repeat circuit is to seal in other circuit after the parallel connection.It is that 26280N H3Y-2 type relay normally open formula connects that time delay relay is selected model for use; It is JB2194 type relay that relay is selected model for use.
Working principle:
During neutral: No. 1 neutral relay (Normally closed type) is from＜7〉number terminal gets, the contact disconnects, time delay relay 1., 2. (open in usual), and No. 4 third gear, No. 5 second gears, No. 2 forward gears, No. 3 reverse gear, relay (open in usual) all must not keep former normally open by electricity, so after installing this circuit additional, does not influence its neutral gear position performance.
When high-grade (fourth gear)+direction controlling rod moves respectively (advance and fall back): speed change lever is when the fourth gear position, and a route must not be electrical contacts closed in No. 1 neutral relay, by＜4〉number terminal line electricity and the time delay relay trigger that 1. communicates.Simultaneously by fourth gear＜1〉1. and 2. number terminal line electricity reach No. 4, third gear by time delay relay, No. 5, second gear, relay contact is connected; During another route direction controlling rod action (advance, move backward), advance＜8〉reversing＜6〉terminal line get electric giving No. 2 or No. 3, adhesive contact＜9 during relay〉electronics line electrical signal is to No. 4 third gear, and No. 5 second gear actuating of relay control two, third gear solenoid valve second gear are started working.After 4 seconds, 2. time delay relay disconnects, and No. 5 the second gear electrical relaybox promptly disconnects, and the second gear blocking-up becomes third gear and starts working.By time delay relay is adjustable prolong 1. number, and initial setting up 8 seconds is prolonged and 2. is initially set to 4 seconds (according to practical situation from ordering), therefore disconnects the fourth gear that can replace work through third gear after 8 seconds.The reverse action principle is the same, is just got electricly through No. 3 by No. 6 terminal lines, works after the adhesive of reversing relay.
During manual one, two, third gear: the speed handle is not when fourth gear, fourth gear＜1〉number terminal pair prolong 2. the input of relay wireless signal, so No. 4 third gear, the all not adhesives of No. 5 second gear relays, advance for No. 2 to making, No. 3 reversing relays input electricity can not conducting, one, two, the third gear solenoid valve promptly and high-grade switch irrelevant.
This circuit Applicable scope, automatic, manually two automatically controlled hydraulic transmission boxes all can install additional.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
