Advantages such as this structure has simply, the practicality strong, convenient operation.
Description
Technical field
The utility model relates to brake field, particularly relates to a kind of cylinder band brake.
Background technique
Band brake utilizes the clamping strap be centered around around Brake drum shrink and produce a kind of break of braking effect.There is good obvolvent performance, take up room the advantage such as little, can use on automatic gearbox, boats and ships, ocean anchor winch, winch and the equipment such as mine winch, builder's winch.Current band brake provide braking force mainly with weight, electromagnet, oil hydraulic cylinder, but all there is shortcoming in various degree.Such as: weight, braking force is immutable, and brake applications is uncontrollable; Electromagnet, oil hydraulic cylinder, though can braking force be controlled, owing to adding Energy control, or the adding of hydraulic system, make structure become complicated, cost is high.
Chinese patent CN103213917A discloses a kind of screw rod motive power type belt brake, comprise: Brake drum, clamping strap, the first block, the second block, connection rod set, piston rod, oil cylinder and handwheel, described Brake drum is arranged on clamping strap, described clamping strap and connection rod set are connected, described first block and the second block are arranged on the left and right sides below Brake drum respectively, the right of described connection rod set connects piston rod, described piston rod coordinates with oil cylinder to be installed, the left side of described connection rod set is provided with handwheel, and this structure provides braking force by screw rod.But screw rod regulates slowly, and inconvenient operation, in structure, mechanically operated node is more, and stability is not high enough.
Model utility content
The cylinder band brake that the utility model provides a kind of combination property outstanding, superior but occur the braking driving mode of distinct disadvantage (such as controlling functions weak, complex structure, complex operation, high in cost of production) to make up current band brake single performance.
For solving the problem, the basic technology scheme that the utility model provides is: cylinder band brake, comprise cylinder, piston, spring, connecting rod, Brake drum, clamping strap, wherein said clamping strap is encircled in described Brake drum, described clamping strap two ends are connected on described connecting rod, and two tie points have certain distance, described rod hinge connection is in a fixed platform, described piston and described spring are positioned at described cylinder, described spring one end connects piston, one end connects described cylinder inner wall end, described piston one end is provided with the piston rod being articulated with described connecting rod.
The resilient support piston of the technical program medi-spring is away from cylinder inner wall, and piston rod band is automatically connected in the link rotatable of one end, link rotatable tension clamping strap, thus realizes braking; In cylinder, pass into gas, promote piston and piston rod reversing motion, drivening rod rotates backward, thus loosen the brake band, brake off; Can the displacement amount of control piston by the gas passing into different amount, the rotation angle of control link, and then the tensioning degree controlling clamping strap, control brake applications.This technological scheme structure is simple, practical, easy to operate.
To the further optimization of basic technology scheme, described connecting rod is curved shape, and connecting rod is divided into two parts by bending point, and the tie point of described clamping strap and described connecting rod lays respectively at two parts.By link design in having certain camber, to increase the area of contact between clamping strap and Brake drum while the length of the body of rod remains unchanged, brake more reliable.
To the further optimization of basic technology scheme, described spring is stage clip, and spring is positioned at described cylinder one end away from plenum chamber.The setting of stage clip, compared with extension spring, just can realize same function owing to not needing to arrange joint at cylinder, more succinct in structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
As shown in Figure 1, this break comprises cylinder 6, piston 4, spring 5, connecting rod 3, Brake drum 1, clamping strap 2, wherein clamping strap 2 is encircled in Brake drum 1, clamping strap 2 two ends are connected on connecting rod 3, and two tie points have certain distance, and connecting rod 3 is articulated with in a fixed platform, piston 4 and spring 5 are positioned at described cylinder 6, spring 5 one end connects piston 4, and one end connects cylinder 6 inwall, and piston 4 one end is provided with the piston rod 41 being articulated with 3 connecting rods.
Spring 5 is stage clip, and spring is positioned at cylinder 6 one end away from plenum chamber, and one end of cylinder 6 is connected with inflator and exhaust passage.
Connecting rod 3 is curved shape, and connecting rod 3 is divided into two parts by bending point, and clamping strap 2 lays respectively at this two parts with the tie point of connecting rod 3.
The resilient support piston 4 of spring 5 is away from cylinder 6 inwall, and the connecting rod 3 that piston rod 41 band is automatically connected in one end rotates, and connecting rod 3 rotates tension clamping strap 2, thus realizes braking; In cylinder 6, pass into gas, promote piston 4 and piston rod 41 reversing motion, drivening rod 3 rotates backward, thus loosen the brake band 2, brake off; Can the displacement amount of control piston 4 by the gas passing into different amount, the rotation angle of control link 3, and then the tensioning degree controlling clamping strap 2, control brake applications.
When needs realization is promptly processed, need open the exhaust passage of cylinder 6 one end, Rapid degassing, spring 5 promotes rapidly piston 4 and makes a response, and drives ensuing a series of brake, realizes fast braking.
