Abstract
The utility model discloses an electric block capable of controlling object descending during power-off, relating to the technical field of hoisting equipment. In a technical scheme provided by the utility model, the electric block mainly comprises a set of electric winding mechanism and two identical sets of counterweight devices, wherein a hoisting motor of the electric winding mechanism is provided with a UPS (Uninterrupted Power Supply) capable of controlling a brake of the hoisting motor, and the weight of a hoisted object is more than counter weights. When power is off, the UPS is connected, the brake is slowly loosened, and the hoisted object descends; when a handle switch is shut off, the UPS is disconnected, the brake is closed, and the descending of the hoisted object is stopped; and in such a way, the UPS is connected and disconnected intermittently so that the electric block gradually lays down the object. According to the technical scheme, the problem that the hoisted object can only be stopped in the mid air and cannot descend when the electric block is in a power-off condition is solved.
Description
Affiliated field:
The utility model is a kind of, and the may command object descends when cutting off the power supply electric block relates to the weight-lifting equipment technical field.
Technical background:
When the standard electric block was met power-off condition, the object that hangs can only be parked in midair, can't in time descend.
Summary of the invention:
When meeting power-off condition for solving electric block, the object that hangs can only be parked in midair, this problem that can't descend, and the utility model provides a kind of electric block that can in time put down object under power down mode, and its technical scheme is as follows:
1, the utility model is a kind of, and the may command object descends when cutting off the power supply electric block mainly is made up of one group of electric winch structure and the identical counter weight device of two covers, and the electric winch structure mainly comprises control housing, lifting motor, retarder and double-rope roll device; Control housing is controlled respectively the braking of lifting motor, and the power line voltage of control motor is to exchange 380V, and the power line voltage of control electromotor brake is direct current 24V, is provided by UPS, and UPS is installed in the control housing the inside; Every cover counter weight device all is made up of a weight box, two cover simply connected pulley gears and steel cable.
2, the utility model the is a kind of may command object descends when cutting off the power supply electric block, the simply connected pulley gear of its electric winch structure and two cover counter weight devices all is installed on the crossbeam of hoist mechanism, the electric winch structure is in the centre of crossbeam, and two cover counter weight devices are at the two ends of crossbeam; The steel rope of counter weight device hangs on two simply connected pulley gears, connects weight box and lifting object, and the lifting weight of object is greater than weight box.
3, the utility model is a kind of, and the may command object descends when cutting off the power supply electric block has 4 suspension centre hoisting heavies, and wherein the electric winch structure has two suspension centres, and counter weight device has two suspension centres; Because counter weight device also participates in lifting operation, so the pulling force that hoists of electric block is relatively littler, so when running into power failure, switching ups power control brake device intermittently unclamps, closes, and can steadily put down the object that hangs.
The ups power of 4, the utility model the is a kind of electric block that the may command object descends when cutting off the power supply under normal circumstances is open circuited, do not influence the electric block normal operation, when meeting power failure or other emergency situation, lifting object and weight box are hung in the air, at this moment open arm cook and connect ups power, slowly unclamp after the drg energising, institute's object that hangs descends; Disconnect ups power when shutting arm cook, drg closes, and makes reel stop, and the object that hangs stops to descend; So intermittently the switching ups power makes electric block steadily put down object one by one.
Description of drawings
The electric block structural representation that the may command object descended when Fig. 1 was a kind of the outage
Wherein:
1, weight box 2, simply connected pulley gear 3, lifting motor
4, retarder 5, double-rope roll device 6, control housing,
The specific embodiment:
This electric block adopts the version of bilateral counterweight, utilizes the counterweight of counterweight and object poor, when meeting power failure or other emergency situation, lifting object and weight box are hung in the air, at this moment open arm cook and connect ups power, slowly unclamp after the drg energising, institute's object that hangs descends; Disconnect ups power when shutting arm cook, drg closes, and makes electric gourd drum stop, and the object that hangs stops to descend; So intermittently the switching ups power makes electric block steadily put down object one by one.
