2, this utility model have employed light current circuit control forceful electric power structure, be provided with earth leakage protective dress in circuit simultaneously Put, ensured the personal safety when using this equipment.

3, this utility model scientific structure design is reasonable, connects by the module integrating in all control loops together Line is simple, easy to operate, uses safety.

Accompanying drawing explanation

Fig. 1 is the circuit theory diagrams of control circuit of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model embodiment is described in further detail:

The control device of construction pipeline auto supply equipment in a kind of subway, as it is shown in figure 1, include casing and inside thereof Control circuit；Described control circuit includes power module, operation button module, promotes relay module and down relay mould Block；Described operation button module is formed by promoting start button, stop button and decline start button；Described lifting relay mould Block includes organizing lifting relay tip more and promoting relay excitation coil contact, and often group promotes relay tip respectively by promoting Before, during and after relay, contact is constituted；Described down relay module includes organizing down relay contact more and down relay is encouraged Magnetic coil contact, often group down relay contact is made up of contact before, during and after down relay respectively；Described power module is adopted Using 24V DC source, this 24V DC source is to be connected with alternating current wire formation by 24V DC source transformator.

In the present embodiment, described lifting relay front contact is connected with motor respectively with down relay front contact Connect；In described lifting relay in contact and down relay contact respectively by the first earth leakage protective device and the second earth leakage protective Device is connected with the first stop and the second stop.

In the present embodiment, promote contact in relay and be connected with alternating current power supply by the first stop, promote relay Device back contact is serially connected between down relay coil contact and 24V DC source；In down relay, contact is by the second limit Position device be connected with alternating current power supply, down relay back contact be serially connected in lifting relay coil contact and 24V DC source it Between, its purpose is to prevent maloperation from causing slide block to skid off slideway and maloperation damages motor.

Operation principle of the present utility model is:

When promoting relay and down relay falls (in the raw), described lifting relay and decline relay The back contact connection that middle contact that device falls is the most corresponding, when promoting relay and down relay picks up, described lifting continues The most corresponding middle contact of front contact that electrical equipment falls with down relay connects.

When stop button in its natural state, stop button contact connect；When pressing stop button, stop button contact Disconnect；Decline start button and promote start button in its natural state, declining start button contact and connect with promoting start button Point disconnects, and when pressing start button or promoting button, declines start button contact and connects with promoting start button contact and protect Hold connected state；When pressing stop button, electric loop is cut off, and declines start button and lifting start button resets and breaks Opening decline start button contact and promote start button contact, stop button resets, stop button contact.

Work process of the present utility model is:

In its natural state, promote relay and down relay is full state, when pressing lifting start button, 24V DC power anode is sequentially connected with contact, down relay back contact (this in lifting start button contact, down relay Time, in down relay, contact connects with down relay back contact), promote relay excitation coil contact, stop button and connect Point and 24V DC power cathode, thus form lifting relay closed-loop path, and then power for promoting relay excitation coil, Now promote relay energized；Therefore, when pressing lifting start button, promote relay and down relay itself forms one Self stick circuit, it is ensured that promoting relay energized and utilize himself front contact for motor, motor rotates forward, and completes to promote Operation.Meanwhile, the another set of this lifting relay promotes relay tip and constitutes the electric loop of motor, electronic Machine startup drives screw turns by decelerator.

When pressing decline start button, 24V DC power anode is sequentially connected with decline start button contact, promotes relay In device, contact, lifting relay back contact (now, promoting contact in relay to connect with promoting relay back contact), decline continue Electrical equipment magnet exciting coil contact, stop button contact and 24V DC power cathode, thus form down relay closed-loop path, enter And be that down relay magnet exciting coil is powered, now down relay falls, and therefore, when pressing decline start button, promotes Relay and down relay itself form a self stick circuit, it is ensured that down relay falls and utilize himself front contact for electricity Motivation is powered, and motor inverts, and completes to decline operation.Meanwhile, the another set down relay of this down relay connects Point constitutes the electric loop of motor, and motor start-up drives leading screw to invert by decelerator.

It is emphasized that embodiment described in the utility model is illustrative rather than determinate, therefore this reality By the novel embodiment including and being not limited to described in detailed description of the invention, every new according to this practicality by those skilled in the art Other embodiments that the technical scheme of type draws, also belong to the scope of this utility model protection.
