Embodiment Construction

[0009] Such as figure 1 As shown, the controller includes an AC contactor 1, a transformer 2, a reverse phase protector 3 and a limit switch 4. The main power line is connected to one end of the AC contactor 1, the transformer 2 is connected to the main power line, and the other end of the transformer 2 One is connected to K2 of reverse phase protector 3, the other end of transformer 2 is connected to A1 of AC contactor coil 1, K0 and K1 of reverse phase protector 3 are respectively connected to limit switch 4 of the hoist, the limit The bit switch 4 is connected with the coil A2 of the AC contactor 1 to form a controller electrical circuit as a whole.

[0010] When working, the hoist motor line is connected to the AC contactor 1. When the hoist works to the upper limit position, the electrical circuit of the controller is disconnected, and the AC contactor 1 stops working, and the same is true for the lower limit position.

Abstract

The invention discloses an electric hoist controller used on a PLC (programmable logic controller) control line. The controller comprises an alternating-current contactor (1), a transformer (2), a reverse-phase protector (3) and a limiting switch (4), a main power source line is connected at one end of the alternating-current contactor (1), the transformer (2) is connected with the main power source line, one line at the other end of the transformer (2) is connected with a K2 of the reverse-phase protector (3), the other line at the other end of the transformer (2) is connected with a coil A1 of the alternating-current contactor (1), a K0 and a K2 on the reverse-phase protector (3) are connected with the limiting switch (4) of a hoist respectively, the limiting switch (4) is connected with a coil A2 of the alternating-current contactor (1), and then an electric loop of the controller is formed integrally. The electric hoist controller is simple in circuit, convenient to operate and stable in operation, the hoist is avoided from hitting the top, parts of the hoist are protected, and maintenance cost is lowered.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to an electric hoist controller used on a PLC control line. Background technique [0002] At present, the electric hoist used on the PLC control line in the market generally does not have an electrical part, and an external travel switch is used to control the travel limit of the hoist, and some even do not have a travel switch. Jumping to the top, causing damage to the hoist parts. Contents of the invention [0003] The object of the present invention is to provide an electric hoist controller used on a PLC control line to protect hoist components. [0004] The technical solution of the present invention is: the controller includes an AC contactor, a transformer, a reverse phase protector and a limit switch, the main power line is connected to one end of the AC contactor, the transformer is connected to the main power line, and a transformer output terminal It is connected to ...
