Embodiment １

[0029] As shown in the figure, the friction brake based on cylindrical locking includes top cover 1, wedge mechanism 2, active rod 3, coupling 4, hydraulic motor 5, driven rod 6, slideway mechanism 7, and stop block 8 and base 9.

[0030] The base 9 is a cuboid structure, and the frame is formed by welding. There is an inverted conical groove in its center, and the stop block moves in the inverted conical groove to clamp or loosen the brake lever.

[0031] The structure of the stop block 8 is shown in FIG. 6 , six M10 socket head cap screws 803 are divided into two rows to fix the friction plate 802 on the stop block main body 801 .

[0032] Base 9 is fixed on the frame, and four stop blocks 8 are as image 3 As shown, it is assembled into the slideway of the slideway mechanism 7, and the upper and lower surfaces of the square connecting body on the upper part of the stopper body 801 are respectively in contact with the upper and lower inner surfaces of the slideway, so that...

Abstract

The invention relates to a friction brake for locking cylindrical parts by four stop blocks. The friction brake comprises such parts as a base, stop block parts, a slide way mechanism, a wedge block mechanism, a driving rod and a driven rod. The driving rod, the driven rod and the slide way mechanism form an altered crank slide block mechanism; a hydraulic motor drives the driving rod to rotate through a coupling; and the driven rod is enabled to push the slide way mechanism to move in the vertical direction so as to drive the stop blocks to move up and down. Meanwhile, the stop blocks respectively finish the actions of braking and releasing under the effects of a conical surface of the base and a wedged part under the wedge block mechanism. When the stop blocks lock a brake rod in a lowest point, a pressure angle on the driven rod is 90 degrees, and the slide way mechanism and the stop blocks are self-locked. The friction brake is compact in structure, smaller in weight and size and easy to arrange, can realize mechanical self-locking in the locking position, is high in braking reliability, can perform braking on whole cylindrical parts, is long in braking distance, and enables the axial braking performances of the cylindrical parts to become better.

Description

technical field [0001] The invention belongs to the technical field of brakes, and in particular relates to a friction brake which utilizes stop blocks to lock cylindrical parts. Background technique [0002] At present, the axial braking of cylindrical parts is mostly in the form of brake lugs on the brake locking parts, and the braking distance is severely limited, which may lead to poor braking effect and even safety problems. [0003] In view of some of the above problems, how to increase the braking distance to make the axial braking of cylindrical parts safe and reliable is the difficulty of designing the brake. Contents of the invention [0004] The object of the present invention is to provide a friction brake based on cylinder locking, which is used for locking and braking cylindrical parts. [0005] A friction brake based on cylindrical locking proposed by the present invention includes a top cover 1, a wedge mechanism 2, an active rod 3, a coupling 4, a hydraul...
