Abstract
The utility model provides a device for parallel operation of a lubricating oil pump and a brake oil pump of a hoist, which belongs to the field of mine hoist safety equipment. The device comprises a power supply circuit, a button, a brake oil pump and a lubricating oil pump, wherein the button is arranged on the power supply circuit, the power supply circuit is connected with the brake oil pump and the lubricating oil pump respectively, and a brake contactor and a lubrication contactor are arranged at the input ends of the brake oil pump and the lubricating oil pump respectively. The device is characterized in that an intermediate contactor is added, the coil of the intermediate contactor is connected in parallel with the coil of the brake contactor, and the two contacts of the intermediate contactor are connected in parallel with the two contacts of the lubrication contactor. The lubricating oil pump and the brake oil pump are powered to run at the same time, thereby preventing the oil-short operation of the hoist lubricating system caused by the carelessness of the hoist operator and reducing the secondary start-up by the hoist operator.
Description
Technical field
The utility model provides a kind of winch lubricating pump and brake pump parallel operation device, belongs to the well winch security appliance field.
Background technology
Mine winder though guaranteed the interlocking of winch and signal, is not realized safe and reliable measure drawing high lubricating of winch after realizing the signal electric blocking.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: a kind of control safety, winch lubricating pump and brake pump parallel operation device easily are provided.
The technical scheme that its technical matters that solves the utility model adopts is: winch lubricating pump and brake pump parallel operation device, comprise feed circuit, button, brake pump and lubricating pump, button is set on the feed circuit, feed circuit connect brake pump and lubricating pump respectively, the input end of brake pump and lubricating pump is provided with braking contactor and lubricating contact device respectively, it is characterized in that: set up the indirect tentaculum, the coil of indirect tentaculum and the coils from parallel connection of coils of braking contactor, two contacts of indirect tentaculum are in parallel with two contacts of lubricating contact device respectively.
On original automatically controlled basis, set up an indirect tentaculum, when brake pump is opened, the adhesive of indirect tentaculum, its normal closure of making war, the adhesive of lubricating contact device, lubricating pump is opened.
As prioritization scheme, in the described supply line thermal protector is set, connect with the coil of braking contactor and lubricating contact device respectively in the contact of thermal protector.Supply line's overload heating triggers thermal protector, disconnects supply line.
As prioritization scheme, fuse is connected in series between the coil of described braking contactor and lubricating contact device and the supply line.A kind of overload protection is provided.
The beneficial effect that the utility model winch lubricating pump and brake pump parallel operation device are had is: guarantee to start beginning at winch one, lubricating system puts into operation simultaneously, fundamentally guaranteed the normal operation of winch, stop because the lubricating system that reasons such as misoperation cause does not move, and the situation of winch running.
Reduce the hoistman restarting after the use, guaranteed to have reached one-shot.Lubricating pump and brake pump simultaneously electric operation, avoided carelessness, and caused winch lubricating system oil starvation operation because of hoistman.
