Embodiment 1

[0033] Such as Figure 1 to Figure 4 As shown, the composite friction braking device of this embodiment includes an installation base 1, a front brake 2 slidingly installed on the installation base 1, and a friction anti-skid assembly 3 for hindering the front brake 2 from sliding, and the front brake 2 includes a seat The body 21 and the two friction plates 22 that are movably installed on the seat body 21 and can move opposite to each other form a friction braking channel 20 for the braked parts to move along the sliding direction of the front brake 2 between the two friction plates 22. The width of the braking channel 20 in the direction perpendicular to the sliding direction of the front brake 2 is smaller than the width of the braked part in the direction perpendicular to the sliding direction of the front brake 2. Blocking assembly 23. When the composite friction braking device of this embodiment is in operation, the braked part moving along the sliding direction of the...

Embodiment 2

[0051] The composite friction braking device of this embodiment is basically the same as that of Embodiment 1, the main difference is that, as Figure 5 to Figure 7 As shown, in this embodiment, the seat body 21 is a cylindrical structure with a through cavity 213, the through cavity 213 penetrates the seat body 21 along the sliding direction of the front brake 2, and two friction plates 22 are located in the through cavity 213, The second sliding rods 24 connected to the two friction plates 22 are respectively slidably disposed on opposite side walls of the seat body 21 . The seat body 21 of this embodiment has no limitation on the length of the braked part, and can be used to brake the braked part with a longer length through the friction braking channel 20, and the seat body 21 of this embodiment is a cylindrical structure, It has high strength, strong bearing capacity, and is not easily deformed, which can greatly reduce the load on the installation foundation 1 .

Abstract

The invention discloses a composite friction braking device. The composite friction braking device comprises an installing foundation, a front brake arranged on the installing foundation in a slidingmanner and a friction sliding resisting assembly used for resisting sliding of the front brake. The front brake comprises a base and two friction plates which are movably arranged on the base and canmove in a back-to-back manner. A friction braking channel for a braked piece to move in the sliding direction of the front brake is formed between the two friction plates. The front brake further comprises an elastic stop assembly used for stopping the back-to-back movement of the two friction plates. The composite friction braking device has the beneficial effects that the structure is simple, the occupied space is small, manufacturing is easy, cost is low, the braking effect is good, and the large-kinetic-energy braked piece can be braked in the small space.

Description

technical field [0001] The invention relates to the technical field of brake equipment, in particular to a composite friction brake device suitable for braking a braked part in translational motion. Background technique [0002] The braking methods for braking the braked parts in translation can be divided into frictional energy absorption, cutting energy absorption, thin-walled structure energy absorption, honeycomb energy absorption, etc. In the usual braking process, the braking device is relatively The installation foundation is fixed, the installation foundation is fixed on the ground, and its bearing capacity is very strong. Therefore, when designing the energy-absorbing structure, there are no strict requirements on the braking load and braking distance, and the installation during the energy-absorbing process is rarely considered. basic carrying capacity. [0003] The fixed brake device has a simple structure and can complete the braking task under most conditions. ...
