Embodiment Construction

[0012] In the present invention figure 1 In the new normally closed brake device shown, the normally closed brake device includes a brake pad 1, a piston 3, a housing 2, a disc spring group 5, a check valve 4, and a hydraulically controlled one-way valve. The piston 3 is installed in the housing 2, and the housing 2 is provided with two left and right oil chambers. The oil passage of the left oil chamber is connected to the first main control oil passage port P1, and the oil passage of the right oil chamber is respectively connected with the check valve 4 and the hydraulic control check valve. One end of the piston 3 is provided with an external thread, which is connected and fixed with the internal thread in the center hole of one end of the brake pad 1, and the other end is pressed together with the disc spring group 6, and the disc spring protective cover 5 is set on the disc spring group 6; Under the action of the elastic force of the disc spring group 6, the piston 3 and...

Abstract

The invention discloses a novel normally closed braking device which is characterized in that a piston is mounted in a housing, a left oil cavity and a right oil cavity are formed in the housing, the oilway of the left oil cavity is connected with a main oil control crossing, and the oilway of the right oil cavity is connected with a check valve and a hydraulic control one-way valve respectively; outer threads are arranged at one end of the piston and are connected with the inner threads in the centre hole at one end of a brake block, the other end of the piston is tightly pressed with a disc spring group, and the disc spring group is sleeved and mounted with disc spring protection cover; the hydraulic control one-way valve is mounted on the housing through bolts, and the built-in spring and valve of the check valve are mounted in the oil inlet in the housing; the device provided by the invention is multifunctional, high in integration level, small in size, simple in structure, and convenient to maintain, has a short journey and big braking force, is capable of implementing braking efficiently, safely and reliably, solves the problem of pulley braking system controlling, and is suitable for popularization and application in various vertical and horizontal braking system.

Description

technical field [0001] The invention relates to a brake device, in particular to a normally closed brake device specially used in a pulley brake system. Background technique [0002] In the tackle braking system, it is required to implement fast and effective deceleration and braking when the tackle with a mass of 4800 kg falls freely from a height of 120 meters and exerts an ejection force of 8 tons, so as to meet the overload and safety requirements of the tackle. In an emergency state, it can ensure the safe braking of the tackle. Common braking devices, such as those used in the fields of automobiles and reels, are generally in a normally open state. By using hydraulic or pneumatic methods to operate the brake pads, the brake pads and brake discs are contacted and rubbed to achieve the purpose of braking. The braking force required for safe braking of a high-speed falling block is at least 20,800 N, and three functions of loose brake, brake, and emergency brake must be ...
