Problems solved by technology

They convert the momentum of the sports car into heat energy through extrusion friction and are absorbed. These three energy absorbers are all extruded by pre-compression. A huge energy impact can easily cause the rope to break; if the squeeze is too loose, the braking distance of the sports car will be too long, which is difficult to meet the requirements

Embodiment Construction

[0026] As shown in the accompanying drawings, the present invention includes a rope mechanism and a buffer energy absorber. The rope mechanism includes a rope, a mounting base 3, a shaft 9, a rope clamp 1 and a turntable 2, and the shaft 9 passes through the mounting base 3 and is supported on the mounting base 3. , one side becomes the installation shaft section of the turntable, and the other side becomes the installation shaft section of the buffer energy absorber. The turntable 2 is assembled on the turntable installation shaft section on the side of the mounting seat 3 through the key 16, and the rope is wound on the turntable 2 through the rope clamp 1. Above, the buffer energy absorber includes the friction plate cover 4, the dynamic friction plate 5, the static friction plate 6, the spring 7, the end cover 11, the push seat 14, the squeeze plate 8 and the stop block 13, and the friction plate cover 4 is installed on the mounting seat 3 On the other side, the three stop ...

Abstract

Disclosed is a torque-changeable buffer power absorber. The torque-changeable buffer power absorber comprises a rope mechanism and a buffer power absorber. The rope mechanism is installed on one side of an installing seat; the buffer power absorber is installed on the other side of the installing seat; a rotating disc of the rope mechanism is connected with the buffer power absorber through a rotary shaft; an extrusion plate of the buffer power absorber is installed on the rotary shaft through threads; a threaded shaft section, matched with the extrusion plate, of the rotary shaft is located between the tail end position when a spring is in an original state and the position where the extrusion plate is located when the spring reaches a maximum compressing state. The torque-changeable buffer power absorber has the advantages of overcoming the defects that the rope of the prior power absorber is easy to break and off the road because the spring is dynamically compressed, bringing positive effect for reducing mine accident losses and guaranteeing personal safety and production safety, being easy to assemble and maintain, and overcoming the defects that being matched with a friction plate, the power absorber is easy to rust and is fixedly combined with the friction plate because a non-asbestos material based on copper and 65 Mn are adopted as matched friction materials.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, in particular to a protective device for a mine sports car, in particular to a protective energy absorber for a mine sports car. Background technique [0002] Inclined shaft transportation is an important part of coal mine production and transportation. Due to reasons such as decoupling of mine cars and broken wires, inclined shaft transportation has become a frequent area of ​​mine transportation accidents. The anti-sports car system is produced in response to the safe transportation of mine trucks. In the anti-sports car system, the energy absorber plays an important role in the performance of the anti-sports car system, and its performance also directly affects the safety factor of the anti-sports car system. [0003] Existing energy absorbers mainly include rope type energy absorbers, platen type energy absorbers and multi-disk type energy absorbers. They convert the momentum of the...
