Specifically, the compression amount of the spring during braking of the conventional brake 420 cannot be adjusted, that is, after the braked carrier is clamped, the position of the brake spring 420 and the position of the lead screw 340 are determined, and cannot be adjusted, after the brake spring 420 is used for a period of time, because the brake spring 420 is partially plastically deformed, the brake spring 420 cannot continuously provide sufficient braking force, and a hidden danger is formed during working; the brake spring 420 of the utility model is arranged in the pushing mechanism 400, the brake spring 420 is compressed when the pushing mechanism 400 is driven by the lead screw 340 to move, the braking force is exerted by the thrust of the lead screw 340 and the elasticity of the brake spring 420, when the braking force needs to be adjusted, the lead screw 340 can be driven to control the moving position of the nut pair 410, and the braking force is convenient to adjust; and the brake spring 420 still leaves a compression room when being subjected to partial plastic deformation, so that the brake force can be kept for a long time by increasing the compression amount of the brake spring 420, which means that even after the braked carrier is clamped, the screw rod can still rotate, further the brake spring 420 is compressed, and the drive nut pair 410 partially displaces towards the spring seat 430, so that the brake force can be kept by compressing the brake spring 420 under the conditions of long-term use and reduced elastic coefficient of the brake spring 420; meanwhile, when the braked carrier is clamped, due to the compression of the braking spring 420, the sufficient braking force can be always kept under the condition of no external force, and the service life of the pushing mechanism 400 is prolonged.

It will be appreciated that the frame 100 is only a platform which carries the brake mechanism 200, the drive mechanism 300 and the push mechanism 400, and that the other two mechanisms, except the brake mechanism 200, are partially hinged to the frame 100, can slide on the frame 100 without the frame 100 participating in movement.

In some embodiments of the present invention, the screw 340 moves under the driving of the driving mechanism 300, and the driving mechanism 300 and the nut pair 410 are pushed away from each other, that is, the housing 320 of the driving mechanism 300 and the nut pair 410 move in opposite directions; the nut pair 410 moves horizontally and the brake spring 420 is compressed, the compressed brake spring 420 applies a pushing force to the spring seat 430, the spring seat 430 in turn drives the second brake shoe 240 in driving connection therewith, the housing 320 of the driving mechanism 300 drives the first brake shoe 230 in driving connection therewith, and the two brake shoes move to clamp the carrier therebetween.

Specifically, because the rotating speed of the outlet of the motor 334 is high, the motor 334 drives the screw rod 340 to move and is inconvenient to control, and therefore the outlet of the motor 334 is connected with the speed reducer 331; a gear 332 is further arranged in the driving device 330, the reducer 331 is connected with the gear 332, and the gear 332 is connected with a screw rod 340; the gear 332 has a larger outer diameter than the reducer 331, so as to provide larger torque to the screw 340; further, the motor is further provided with a one-way clutch for preventing the screw 340 from rotating reversely.

It is understood that the gear 332 is not limited to be connected to the reducer 331, but other transmission mechanisms such as a chain transmission or a belt transmission can be used; the reverse rotation of the screw 340 can be limited in other ways, such as providing a band-type brake self-locking device on the motor 334, or providing a ratchet on the reducer 331 or the gear 332.
