Problems solved by technology

[0003] However, on the one hand, the braking force of the electro-hydraulic pusher is small, which cannot meet the requirements of the winch braking torque. If the winch is braked by manual operation, the braking force is small, and it cannot meet the braking requirements of the winch. Hidden dangers, and the labor intensity of the operators is very high; on the other hand, since the working brake and the clutch are manually operated, it may lead to misoperation of the working brake and the clutch at the same time, and the consequences of this operation will lead to The internal gear of the winch is broken;

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] Such as figure 1 Shown: a transport winch hydraulic braking device, including the rear support 1 installed on the transport winch, the rear support 1 is connected with one end of the rear brake arm 6 through the pin shaft Ⅵ21, and is in contact with the rear support 1 A left anti-yaw block 3 is installed at one end of the rear brake arm 6, and the left anti-yaw block 3 can adjust the yaw amount of the rear brake arm 6 through the left adjustment screw 2, so that the rear brake arm 6 is in a reasonable position. position, the rear brake block 4 is installed on the rear brake arm 6 through the pin shaft I5, the other end of the rear brake arm 6 is connected to the brake hydraulic cylinder 8 through the pin shaft II7, and the piston rod of the brake hydraulic cylinder 8 is passed through the adjustment nut 10 is connected with one end of the connecting rod 12, the conn...

Abstract

The invention discloses a hydraulic brake apparatus of a haulage winch. The other end of a rear brake arm (6) is connected with a braking hydraulic ram (8) through a pin roll II (7). The piston rod of the braking hydraulic ram is connected with one end of a connecting rod through an adjusting nut (10). The other end of the connecting rod (12) is connected with the other end of a front brake arm (14) through a pin roll III (13). The brake apparatus uses the hydraulic ram to brake, so braking forces are larger, and brake is safe and reliable. The brake apparatus can be far away from a controlled winch, and labor intensity of workers is greatly reduced. The brake apparatus can prevent gear damage phenomenon in a winch, and ensures operation safety of winch.

Description

technical field [0001] The invention relates to a hydraulic brake device, in particular to a hydraulic brake device for a transport winch, which belongs to the field of brake devices. Background technique [0002] In my country's coal mine industry, the transport winch is mainly used in coal mines and other mines in roadways with an inclination angle of less than 30° to pull mine cars. Generally speaking, the transport winch brakes the emergency or faulty winch drum through the electro-hydraulic pusher on the safety brake; the use of the working brake can stop the winch drum without stopping Brake; Clutch can control the operation and stop of the winch. [0003] However, on the one hand, the braking force of the electro-hydraulic pusher is small, which cannot meet the requirements of the winch braking torque. If the winch is braked by manual operation, the braking force is small, and it cannot meet the braking requirements of the winch. Hidden dangers, and the labor intens...
