Problems solved by technology

The prime mover is the hoisting mechanism of the hydraulic motor, which can realize the stable parking and secondary lifting of the hoisting mechanism through the comprehensive action of various hydraulic valves, solenoid valves, brakes, etc.; The shortcomings of the mechanism are also obvious: more equipment makes the equipment cost higher, higher energy consumption makes the use cost higher; so in general, when the motor can be used as the prime mover, it is more economical and practical to use the motor as the prime mover s Choice
Now in the market, for the hoisting mechanism using the motor as the prime mover, the brakes used are basically ordinary brakes. The brakes are required to be opened at the moment the motor is started, but the motor cannot quickly form enough torque in a short period of time, which is very likely. Cause the hoisting mechanism to slide; especially the second hoisting under the condition of load, if the load is too heavy, it may cause serious accidents

Embodiment Construction

[0017] The present invention will be further described below according to the accompanying drawings and embodiments.

[0018] Such as Figure 1 to Figure 3 As shown, a lifting brake includes a brake shaft 1, the two ends of the brake shaft 1 have external splines, one end of the brake shaft 1 is connected to the motor, and the other end of the brake shaft 1 is connected to the reducer , to transmit the torque from the motor to the reducer. The middle part of brake shaft 1 is fitted with bearing seat 20, one-way brake wheel 24, brake wheel 27 and brake seat 7 successively, between bearing seat 20, one-way brake wheel 24 and brake seat 7 and brake shaft 1 Bearings are installed, and the outer circumference of the one-way brake wheel 24 is connected with a brake device I, and the brake device I includes a one-way brake pad 16 and a one-way friction pad 17, and the one-way brake pad 16 is connected with the one-way brake pad 17. The brake housing 25 is spline connected, and the ...

Abstract

The invention belongs to the technical field of brakes, and in particular relates to a lifting brake, which includes a brake shaft, on which a bearing seat, a one-way brake wheel, a brake wheel and a brake seat are sequentially set, and the one-way brake A brake device I is connected to the outer circumference of the wheel, a one-way bearing is set between the one-way brake wheel and the brake shaft, and a brake device II is connected to the outer circumference of the brake wheel. The brake wheel is connected to the brake shaft; the other end of the brake device I and the other end of the brake device II are connected to the brake housing; the hoisting mechanism can be lifted and parked accurately and smoothly. And the structure of the present application can guarantee that there is no slipping phenomenon in the secondary lifting.

Description

technical field [0001] The invention belongs to the technical field of brakes, in particular to a lifting brake. Background technique [0002] A complete hoisting mechanism generally includes: prime mover (and its related power source, etc.), brake, reducer (some lifting mechanisms have no reducer) and drum, etc. According to different prime movers, it can be divided into hydraulic motor-driven lifting mechanism and motor-driven lifting mechanism. The prime mover is the hoisting mechanism of the hydraulic motor, which can realize the stable parking and secondary lifting of the hoisting mechanism through the comprehensive action of various hydraulic valves, solenoid valves, brakes, etc.; The shortcomings of the mechanism are also obvious: more equipment makes the equipment cost higher, higher energy consumption makes the use cost higher; so in general, when the motor can be used as the prime mover, it is more economical and practical to use the motor as the prime mover s Ch...
