Abstract

The utility model discloses a hoisting mechanism with a variable speed function. The hoisting mechanism with the variable speed function comprises a coiling block (16), wherein a first-class planet carrier (8), a first-class gear ring (7), a first-class planet wheel (6), a first-class sun wheel (5), a second-glass planet wheel (14), a second-class sun wheel (13), an input sleeve (1), a second-class gear ring (15) and an arrester (3) are arranged inside the coiling block (16). A clutch device is arranged among the first-class planet carrier (8), the first-class gear ring (7) and the second-class gear ring (15). The hoisting mechanism with the variable speed function is simple in structure and cheap in improving cost. The clutch device which is formed by a zygote, a pull rod and a piston is arranged among the first-class planet carrier, the first-class gear ring and the second-class gear ring so as to achieve the change of a hoisting mechanism speed ratio, meet the needs of different working conditions, largely improve the work efficiency, and accordingly improve economic benefits produced by the whole vehicle.

Description

A kind of lifting mechanism with speed changing function

Technical field

The utility model relates to mechanical field, and specifically a kind of lifting mechanism with speed changing function is mainly used in construction machinery and equipment, car hosit industry.

Background technology

The lifting mechanism that adopts at Crane Industry at present is widely adopted because of the characteristics that planetary transmission has compact conformation, stable drive, but under normal circumstances, the planetary transmission speed ratio is fixed, also be that the speed of lifting mechanism in real work is single, thereby can't select suitable work speed according to concrete operating environment, affect significantly the economic benefit that operating efficiency and car load can produce.

Summary of the invention

For solving the technical matters of above-mentioned existence, the utility model provides a kind of lifting mechanism with speed changing function, in the situation that the slow running of the heavier employing of lifting object large speed ratio, in the situation that lifting object is lighter, adopt little speed ratio high speed operation, can increase substantially work efficiency.

For achieving the above object, the technical scheme that the utility model adopts is as follows:

A kind of lifting mechanism with speed changing function, include reel, described reel inside is provided with primary planet carrier, primary annulus, the one-level satellite gear, the one-level sun wheel, the secondary planet wheel, secondary solar gear, the input cover, secondary gear ring and brake plate, at described primary planet carrier, be provided with arrangement of clutch between primary annulus and the secondary gear ring, described arrangement of clutch includes zygote, pull bar and piston, be provided with male splines on the described zygote, be provided with the female splines corresponding with male splines on the described zygote on the described primary annulus, be provided with the female splines corresponding with male splines on the described zygote on the back seat of described primary planet carrier and secondary gear ring, described pull bar one end is connected with described zygote, the other end is connected with piston.

The utility model is simple in structure, improve with low cost, between primary planet carrier, primary annulus and secondary gear ring, be provided with the arrangement of clutch that is formed by zygote, pull bar, piston, when dynamic input, zygote can drive primary annulus and present and be combined or be combined with the secondary gear ring two kinds of position relationships with primary planet carrier, realizes the variation of lifting mechanism speed ratio, thereby satisfies the demand of different operating modes, significantly improve work efficiency, thereby improved the economic benefit that car load can produce.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in detail:

Be a specific embodiment of the present utility model as depicted in figs. 1 and 2, include reel 16, described reel 16 inside are provided with primary planet carrier 8, primary annulus 7, one-level satellite gear 6, one-level sun wheel 5, secondary planet wheel 14, secondary solar gear 13, input cover 1, secondary gear ring 15 and brake plate 3, at described primary planet carrier 8, be provided with arrangement of clutch between primary annulus 7 and the secondary gear ring 15, described arrangement of clutch includes zygote 10, pull bar 11 and piston 12, be provided with male splines on the described zygote 10, be provided with the female splines corresponding with male splines on the described zygote 10 on the described primary annulus 7, be provided with the female splines corresponding with male splines on the described zygote 10 on the back seat 9 of described primary planet carrier 8 and secondary gear ring 15, described pull bar 11 1 ends are connected with described zygote 10, the other end is connected with piston 12.

In the situation that the lifting heavy duty, the utility model adopts high speed than the state of low-speed running, and oilhole I 2 and oilhole II 4 all enter high pressure oil, and brake plate 3 separates, and pushing piston 12 is pushing drawing rod 11 to the right, drives zygote 10 to position shown in Figure 1.At this moment, primary annulus 7 connects there is no with the back seat 9 of secondary gear ring 15 by zygote 10 and relatively rotates.The motor input power, drive one-level sun wheel 5, drive one-level satellite gear 6, drive primary planet carrier 8, drive secondary solar gear 13, drive secondary planet wheel 14, drive secondary gear ring 15, be with movable reel 16 rotations through inputting cover 1, realize under the severe duty at a high speed than low-speed running.

In the situation that the lifting underloading, the utility model adopts low speed than the state of high-speed operation, and at this moment, oilhole I 2 enters high pressure oil, and brake plate 3 separates; Oilhole II 4 emptyings, pull bar 11 push position shown in Figure 2 in connection with son 10 under spring thrust, at this moment, primary planet carrier 8 connects by zygote 10 with primary annulus 7, without relatively rotating.The motor input power drives one-level sun wheel 5 through input cover 1, driving primary annulus 7 through one-level satellite gear 6 rotates simultaneously with primary planet carrier 8, be that one-level sun wheel 5, primary annulus 7, primary planet carrier 8 are fixed as one, unitary rotation, speed ratio is 1, drives secondary solar gear 13, drives secondary planet wheel 14, drives secondary gear ring 15, is with movable reel 16 to realize that light duty low speed compares high-speed operation.

Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
