Abstract
The utility model discloses a hydraulic spanner automatic control device which comprises a hydraulic spanner manual control circuit and is characterized in that automatic buttons are connected in parallel on the manual control circuit, and the manual control circuit is connected with an identical or progressive period cyclic time relay automatic control circuit. The hydraulic spanner automatic control device adopts an identical or progressive period cyclic time relay to automatically control the make and break of an electromagnet DT of a hydraulic valve to realize automatic control of the motion of the hydraulic spanner, so that the hydraulic spanner can rotate to the top and automatically restore and circulate continuously to replace the fussy manual control operation. The hydraulic spanner automatic control device reduces the labor intensity and particularly saves the troubles of difficult operation and inconveniency when a plurality of hydraulic spanners work synchronously at the same time.
Description
Background technology
The utility model belongs to circuit control device, is specifically related to a kind of control device of hydraulic spanner.
Background technology
Existing hydraulic spanner all adopts manual line traffic control operation, and its manual control circuit comprises, automatic air circuit breaker JRS, Switching Power Supply TC, temperature detect switch (TDS) LM, contactor CJX and hand push button SA.The every work of hydraulic spanner once needs manually-operated to pin hand push button all the time, can not move automatically continuously.Te Jiabie is many hydraulic spanners when working asynchronously simultaneously, complex operation, and labour intensity is big.
Summary of the invention
The purpose of this utility model is to provide a kind of can realize the hydraulic spanner hydraulic spanner automaton of control automatically, to address the above problem.
The technical solution of the utility model is: the hydraulic spanner automaton, it comprises the hydraulic spanner manual control circuit, it is characterized in that the cycle such as automatic button and connection circulates or laddering loop cycle time relay automatic control circuit side by side on the manual control circuit.
This device utilization waits the cycle circulation or the laddering loop cycle time relay to control the break-make of hydraulic valve electromagnet DT automatically, realize the automatic control of hydraulic spanner action, thereby realizing that hydraulic spanner has to revolve the top and reset connects continuing circulation automatically and substitutes loaded down with trivial details manually-operated automation control.Reduce labor intensity, particularly improve the troublesome poeration and inconvenience that bring when many hydraulic spanners work asynchronously simultaneously.
Description of drawings
Fig. 1 is the utility model Automatic Control Theory structure chart.
The specific embodiment
Present embodiment is used for the explanation to the utility model claim; protection domain of the present utility model is not limited to the description of following structure, and the realization hydraulic spanner that those skilled in the art proposes according to the technical scheme of claim 1 has to revolve the top and reset and connects continuing circulation automatically and drop in the protection domain of the present utility model for the action control structure.
As shown in Figure 1, press the spanner automatic control system, comprise automatic air circuit breaker JRS, Switching Power Supply TC, temperature detect switch (TDS) LM, contactor CJX, etc. cycle circulation or laddering loop cycle time relay sj, stop button TA, start button QA, change-over switch K, hand push button SA constitute.Motor is connected in after the automatic air circuit breaker JRS.(before the Switching Power Supply) is in series with normally-closed contact JRS1 and the temperature control switch normally-closed contact LM of automatic air circuit breaker JRS in the major loop.Switching Power Supply TC is elementary to join with the alternating current 220V major loop, and it is secondary to join with control loop.Motor contactor coil CJX connects with stop button TA and start button QA.Time relay coil SJ is connected in series the back with manual automatic transfer switch K in parallel with contactor coil CJX.Time relay sj often open that its output and hydraulic valve electromagnet DT join after timing closing contact and the manual operation button SA parallel connection, (electromagnet DT is connected in the Switching Power Supply output) its input is connected to after the stop button TA.Stop button TA is serially connected on the control loop main line.The attached contact CJX1 that helps of contactor CJX is in parallel with start button QA.Temperature detect switch (TDS) places the fuel tank side, and contacts with tank wall.
Automatically during control, closed change-over switch K connects continuing circulation automatically for moving by unclamping behind the start button QA just can make hydraulic spanner revolve the top and reset.Stop action by stop button TA hydraulic spanner.
Claims (2)
1, a kind of hydraulic spanner automaton, it comprises the hydraulic spanner manual control circuit, it is characterized in that the cycle such as automatic button and connection circulates or laddering loop cycle time relay automatic control circuit side by side on the manual control circuit.
2, hydraulic spanner automaton according to claim 1, the hand push button that it is characterized in that manual control circuit and the described time relay often to open the timing closing contact in parallel; Described time relay automatic control circuit such as comprises at cycle circulation or laddering loop cycle time relay sj, the change-over switch K that time relay sj is connected in series; Time relay sj and hand push button are connected to start button QA; And stop button TA.
