Abstract
The utility model relates to an overspeed protective device for a hoisting window cleaning machine, being composed of a trigger mechanism and braking mechanism. The operating mode of the device is that when a hoisting mechanism is driven to do uniform rotation, the device can so uniform rotation along with the hoisting mechanism; when the hoisting mechanism runs at overspeed, the trigger mechanism can immediate drive a brake block in the braking mechanism to tightly embrace a braking hub, and accordingly, the device can play a protective role for the overspeed of the hoisting mechanism. The utility model has the advantages of simple structure, sensitive trigger mechanism and reliable working; the utility model also has the advantage that the function of the safety protection after overspeed for the lifting mechanism of a hoisting window cleaning machine can be easily realized. The device is suitable for hoisting mechanisms of hoisting machinery in construction.
Description
The utility model belongs to a kind of hypervelocity safety guard of winding type window cleaning equipment lifting mechanism.
Lifting mechanism at China's external wall of high-rise building cleaning and the used rail mounted window cleaning equipment of service equipment adopts the elevator form mostly; for guaranteeing the safe and reliable of lifting mechanism; prevent from work to cause because of motor or other driving member lose efficacy that the stall of work hanging basket descends, and must be provided with fast protective device.The protective device of more domestic window cleaning equipments adopts automatic load sustaining brake and block brake mostly at present, and the impact that produces during work is bigger, and trigger mechanism is sensitive inadequately, and security reliability is not high.
The purpose of this utility model provides a kind of overspeed protective device of novel winding type window cleaning equipment, and this apparatus structure is simple, and reliable operation can easily realize the safeguard protection effect after the winding type window cleaning equipment lifting mechanism hypervelocity.
The overspeed protective device of a kind of winding type window cleaning equipment of the present utility model, form by trigger mechanism, arrestment mechanism, it is characterized in that: trigger mechanism comprises plum blossom wheel, swing arm, fulcrum wheel, connecting rod, balancing weight and eccentric mounting, arrestment mechanism comprises brake arm, brake block, braking hub, connecting rod, adjusting screw(rod), spring base, spring, and the braking hub is arranged in the plum blossom wheel; At two brake arms of braking hub upper and lower settings, in the centre of brake arm brake block is set, an end of brake arm is connected with the elevating mechanism frame, the connecting rod of hinged " eight " font of the other end of last brake arm, following brake arm is connected with a cuboid connecting rod; The connecting rod of cuboid is provided with adjusting screw(rod), swing arm and eccentric mounting, the top of swing arm is provided with pinch roller, be pressed on the plum blossom wheel, the middle part of swing arm is connected with the cuboid connecting rod, and the bottom is placed with balancing weight, and eccentric mounting is connected with the connecting rod of cuboid, one fulcrum wheel is set in the upper end of eccentric mounting, the fulcrum wheel is connected with spring base with spring, and the upper end of adjusting screw(rod) is hinged with " eight " font connecting rod one end, and the upper end of spring base is hinged with the other end of " eight " word connecting rod.
The course of work of the present utility model: braking hub and plum blossom wheel are connected an end of hoisting mechanism, when under the drive of hoisting mechanism reel at motor reducer during uniform rotation, braking hub and plum blossom wheel are with the hoisting mechanism uniform rotation, and at this moment the pinch roller on the swing arm is pressed in the plum blossom wheel and goes up smooth rotation; When the hoisting mechanism overspeed operation; swing arm is thrown out of at once the cuboid connecting rod is moved to right eccentric mounting; and make eccentric mounting clash into limit switch on the frame on the one hand; make fulcrum wheel under the effect of spring, slide an end of drive " eight " font connecting rod and the brake arm on top moves downward simultaneously on the other hand from eccentric mounting; the other end of " eight " font connecting rod moves upward; the brake arm that is driven the bottom by adjusting screw(rod) moves upward; make brake block hold the braking hub tightly, play effect the overspeed protection of hoisting mechanism braking.
The overspeed protective device of a kind of winding type window cleaning equipment of the present utility model, simple in structure, the trigger mechanism sensitivity, reliable operation can easily realize the safeguard protection effect after winding type window cleaning equipment lifting mechanism exceeds the speed limit.This device is suitable for the hoisting mechanism with building crane.
Be described further below in conjunction with the overspeed protective device of drawings and Examples the winding type window cleaning equipment.
Fig. 1 is the structural representation of the overspeed protective device of winding type window cleaning equipment
As can be seen, a kind of overspeed protective device of winding type window cleaning equipment, form by trigger mechanism, arrestment mechanism, it is characterized in that: trigger mechanism comprises plum blossom wheel 1, swing arm 9, fulcrum wheel 10, rectangle connecting rod 11, balancing weight 12 and eccentric mounting 13, arrestment mechanism comprise brake arm 2, brake block 3, braking hub 4, Eight characters connecting rod 5, adjusting screw(rod) 6, spring base 7, spring 8; Braking hub 4 and plum blossom wheel 1 are connected an end of hoisting mechanism; Two brake arms 2 up and down are set on the braking hub, and an end of brake arm is connected with the elevating mechanism frame, the connecting rod 5 of hinged " eight " font of the other end of last brake arm, and following brake arm is connected with a cuboid connecting rod 11, in the centre of brake arm brake block 3 is set; The connecting rod of cuboid is provided with adjusting screw(rod) 6, swing arm 9 and eccentric mounting 13, the top of swing arm is provided with pinch roller 14, be pressed on the plum blossom wheel, the middle part of swing arm is connected with the cuboid connecting rod, and the bottom is placed with balancing weight, and eccentric mounting is connected with the connecting rod of cuboid, one fulcrum wheel 10 is set in the upper end of eccentric mounting, the fulcrum wheel is connected with spring base with spring, and the upper end of adjusting screw(rod) is hinged with " eight " font connecting rod one end, and the upper end of spring base is hinged with the other end of " eight " word connecting rod.
