Description

(54) ELEVATOR BUFFER

one

The invention relates to a lifting and transporting device, in particular to elevator buffers.

The elevator buffer is known, which contains a support element mounted on a support by means of a clamp, a brake element and a head cooperating with a power element of the elevator car having guides 1.

However, the well-known buffer requires a sufficiently powerful and metal-consuming lower beam, fo which interacts with the buffers in its middle part and must withstand a substantial dynamic load when landing on the buffers. This buffer also requires specifically for building supports. In addition to this, the placement of the building supports and the buffers themselves in the middle part of the ground is cluttered up at the ice and makes it difficult to maintain the equipment of the ground water. Installation of known buffers also requires considerable labor costs.

The purpose of the invention is to reduce the metal intensity by eliminating the force effects on the central part of the lower surface of the elevator canal.

The goal is achieved in that the cutout in the buffer head is shaped according to the shape of the elevator guide, which is passed inside the brake element through said cutout.

FIG. 1 shows schematically the proposed buffer, the general view; in fig. 2 - the same, top view The buffer contains a brake element 2 mounted on the support 1, mounted by means of a clamp 3, a buffer head 4 with a gasket, interacting with the power element 5 of the elevator car 6. Inside element 2, an elevator guide 7 is placed, which also serves to maintain the longitudinal stability of the shock absorber under compression.

In the buffer head 4, a cutout is made, corresponding to the perimeter of the working part of the elevator guide, which is located in the cutout a.

The buffer works as follows.

During an emergency transition by the cab 6 of its working position, it acts with its 3 9 force element 5 on the buffer head 4, which transmits the force to the upper elastic part of the element 2, made in the form of a spiral compression spring, and its movement occurs, acting on the cab 6 and stopping it. The element 5 of the cab 6 is made in the form of a fork, partially covering the guide 7, which maximally brings the interaction zone of the power element 5 and the buffer head 4 to the longitudinal axis of the element 2. The proposed device makes it possible to have cabins without a metal-consuming and expensive lower beam, usually made of channels, fitted with plates, and fixed to the floor frame. The buffer, thus designed, transfers the load from the buffer directly to the frame and poly side walls of the cab frame. In addition, this device does not require the use of a guide tube, which also reduces the metal consumption. Since the proposed buffer is placed on the same plate or building support on which the elevator guide is installed, the installation of the buffer does not require a special 1 plate and a building support, and also frees up the middle, which improves the safety and ease of maintenance of its equipment. Claims of the invention. A lift buffer containing a braking element mounted on a support by means of a clamp and a head cooperating with a power element of an elevator car, having guides in which, in order to reduce metal consumption, by eliminating force effects on the central part of the lower surface of the elevator car, The buffer head is formed in the form of an elevator guide which is passed through the aforementioned head cut through the inside of the brake element.
