Embodiment 1

[0026] refer to figure 1 with figure 2 , a novel boiler manned maintenance platform traction winch braking device includes a braking device 100 and a connecting device 200 .

[0027] The braking device 100 can make the moving or running unit achieve the purpose of deceleration or parking, which includes a motor 101 for providing power; a working brake 102 arranged on the main shaft of the motor 101 for emergency braking; The speed reducer 103 connected to the motor 101, the speed reducer 103 mainly plays the role of reducing the rotating speed of the prime mover; the reel 104 connected with the reducer 103, the reel 104 is used to wind the wire rope and transmit power; and the reel 104 A plurality of disc brakes 105 are connected; and a hydraulic station 106 connected with the disc brakes 105 is used for emergency braking of the disc brakes 105 .

[0028] When the winch needs emergency braking, the motor 101 is turned off, the working brake 102 is used for emergency braking...

Embodiment 2

[0033] refer to image 3 with Figure 4 , this embodiment is different from the first embodiment in that: the connecting device 200 is more stable when working.

[0034] One end of the first shaft coupling 201 close to the second shaft coupling 202 is provided with four connection grooves 201a, and the four connection grooves 201 are equidistantly arranged on the first shaft coupling 201; the second shaft coupling 202 is adjacent to the second shaft coupling 202 One end of a coupling 201 is provided with four connecting blocks 202a, which are equidistantly arranged on the second coupling 202; the connecting blocks 202a are inserted in the connecting groove 201a.

[0035]Preferably, the cross section of the connection block 202a and the connection groove 201a is a circle, the outer wall of the connection block 202a is smooth, the inner wall of the connection groove 201a is smooth, and the notch cross section of the connection groove 201a is slightly larger than the cross secti...

Embodiment 3

[0041] refer to Figure 5 , this embodiment is different from the above embodiments in that: the braking force is greater, and the failure of one of the braking units will not lead to the failure of the entire brake

[0042] Brake discs 104a are provided at both ends of the reel 104, and four disc brakes 105 are arranged symmetrically on both sides of the two brake discs 104a; when emergency braking occurs, the force of the disc brakes 105 will The position above the brake frying pan 104a is not on the main body of the reel 104, which can greatly reduce the heat load and mechanical friction on the surface of the reel 104.

[0043] Further, the disc brake 105 is provided with a contact block 105a, a disc spring 105b and a hydraulic cylinder 105c connected in sequence, the contact block 105a is in contact with the brake disc 104a, and the hydraulic cylinder 105c is connected with the hydraulic station 106 . The braking force of the hydraulic cylinder 105c is far greater than th...

Abstract

The invention discloses a novel boiler manned maintenance platform traction winch brake device. The novel boiler manned maintenance platform traction winch brake device comprises a brake device and a connecting device, wherein the brake device comprises a motor, a working damper brake, a speed reducer, a winding drum connected to the speed reducer, a plurality of disc brakes connected to the winding drum, and a hydraulic station connected to the disc brakes, wherein the working damper brake and the speed reducer are connected to the motor, the connecting device comprises a first coupler and a second coupler which are connected in a matching mode and a containing shell connected to the motor, the first coupler is connected to the speed reducer, an opening is formed in the containing shell in the direction orienting the first coupler, the second coupler penetrates through the opening to be arranged in the containing shell and is connected to the containing shell through a spring, the spring is arranged in the axial direction of the second coupler, a pushing piece is arranged at the end, close to the motor, inside the containing shell, and the length of the pushing piece is greater than the length from the second coupler to the end, close to the motor, of the containing shell. The device is large in braking force and provided with a plurality of braking units, the whole damper brake cannot lose efficacy even if one of the braking units loses efficacy, the motor and the speed reducer can be rapidly separated, a power source is cut off, and rapid braking is achieved.

Description

technical field [0001] The invention relates to the technical field of a manned winch, in particular to a novel braking device for a traction winch of a boiler manned maintenance platform. Background technique [0002] The active winch safety brake (safety brake) adopts a heavy hammer-belt brake structure and is a single-line brake, which has potential safety hazards. In addition, there have been accidents in our factory. The active winch braking force is not enough and not fast enough. As a manned lifting device, there is a major safety hazard. Hidden danger.
