Rubber spring shear sheet combination type elevator damper with guide sleeve

Abstract

The invention relates to an elevator damper, in particular to a rubber spring shear sheet combination type elevator damper with a guide sleeve. A collision head is arranged on a top end of a force guide sleeve, the bottom end of the force guide sleeve is connected with a spring, the spring is arranged on a bottom plate, the guide sleeve is arranged outside the spring, the connection end of the force guide sleeve and the spring extends into the guide sleeve, a fixed part is fixedly arranged on the bottom plate and is arranged on one side of the force guide sleeve, one end of a mild steel damper is connected with one end of an extension end of the force guide sleeve in the guide sleeve, and the other end of the mild steel damper is connected with the fixed part. The rubber spring shear sheet combination type elevator damper with the guide sleeve provided by the invention can provide stable damping force. A core energy consumption part, i.e. a shear sheet can be used in a reciprocating manner and provide stable performance. The guide sleeve part is additionally arranged and can well enable the damper to do ideal set up and down energy consumption motion during the whole collision process, so that the reliability of the damper is increased and the service life of the damper is prolonged.

Description

Technical field [0001] The invention relates to a damper for an elevator, in particular to an elevator damper of a rubber spring shear sheet combined type with a guide sleeve. Background technique [0002] When the elevator descending speed is greater than 1 meter per second, energy-consuming dampers can meet the collision demand. Therefore, the present invention provides an elevator damper with a combination of rubber spring and shear blades. The quick recovery of the performance of the damper is an important requirement, so the shears must be able to be replaced quickly or set in the opposite direction for repeated use. At the same time, when the trajectory of the shears is not restricted, the shears may be Out-of-plane force is generated, which makes the energy consumption performance of the shear blade unstable. Summary of the invention [0003] In view of the above-mentioned shortcomings, the present invention provides a rubber spring shear piece combined elevator damper wi...

The performance of the fast recovery damper is an important requirement, so the shear piece must be able to be replaced quickly or set in the opposite direction for repeated use. At the same time, when the movement track of the shear piece is not constrained, the shear piece may be damaged Generate out-of-plane force, so that the energy dissipation performance of the shear sheet is unstable
