Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as Figures 1 to 4 The new sliding device of the additional brake shown includes a ratchet 10, a brake disc 20 and a brake pressure disc 30, the brake disc 20 is arranged between the ratchet 10 and the brake pressure disc 20, and the brake disc 30 pushes the brake disc 20 is press-fitted with ratchet 10 to generate braking force. The ratchet 10 is provided with a mounting hole, and the brake disc 20 is fitted and connected with the mounting hole. In the axial direction, a brake pad is arranged between the brake disc 20 and the installation hole, and the brake pad is neither bonded to the brake disc 20 nor to the ratchet 10 . The ratchet 10 is radially positioned by the brake pad and the brake disc 20 . In this embodiment, the brake pad is made of aluminum alloy, while the brake disc 20 and the ratchet 10 are made of Q235-A. In the radial...

Abstract

The invention discloses a novel sliding device of an auxiliary brake. The novel sliding device comprises a ratchet wheel, a brake disk and a brake pressing disk. The brake disk is arranged between the ratchet wheel and the brake pressing disk, and the brake pressing disk presses the brake disk and the ratchet wheel together to produce brake force. The novel sliding device of the auxiliary brake is simple and compact in structure, low in installation space requirement, and long in service life, and brake force is simple and convenient to regulate.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a novel sliding device with an additional brake. Background technique [0002] The additional brake ratchet device currently on the market has a complex structure, takes up a large space, and is inconvenient to adjust the braking force. When maintaining the additional brake at the engineering site, the steps need to be disassembled, and the maintenance efficiency is low. Contents of the invention [0003] Based on this, it is necessary to provide a new type of sliding device with an additional brake that is simple and compact in structure, requires less installation space, is simple and convenient to adjust the braking force, has a long service life, and is easy to disassemble. [0004] Its technical scheme is as follows. [0005] A new type of sliding device with an additional brake, comprising a ratchet, a brake disc and a brake pressure disc, the brake disc is arranged be...
