Gantry type multi-group wire saw machine lifting guide rail rolling mechanism

Abstract

The invention discloses a lifting guide rail rolling mechanism for a gantry type multi-group wire saw. The lifting guide rail rolling mechanism for the gantry type multi-group wire saw is mainly composed of a movable base body, a rolling body and a guide rail, wherein the movable base body rolls on the surface of the guide rail through the rolling body, the rolling body comprises at least two fixed bearing blocks and a movable bearing block, and the movable bearing block is installed between the two fixed bearing blocks; the fixed bearing blocks and the movable bearing block are provided with a downwards-opened concave cavity respectively, and a rolling bearing is installed in each concave cavity; and the movable base body is provided with a locking device, and the locking device forms fixed locking with the fixed bearing blocks on the rolling body, and forms vertically-shocking locking with the movable bearing block. The lifting guide rail rolling mechanism for the gantry type multi-group wire saw, which is disclosed by the invention, is compact in structure, easy to install, capable of buffering, and quite applicable to occasions with narrow spaces and vibration.

Description

technical field [0001] The invention relates to a guide rail rolling body, in particular to a gantry type multi-group wire saw machine lifting guide rail rolling mechanism. Background technique [0002] Stone mining has now entered a development stage of large-scale billet mining and high efficiency. Especially the processing of large granite slabs requires higher efficiency. In this context, it is urgent to develop large-scale slate cutting and forming equipment. [0003] For this reason, the applicant has developed a large-scale multi-group wire saw machine, and the whole gantry part including the cutting head moves up and down along the four-sided guide rails of the double columns to realize the cutting action. Because the gantry part hangs outside the front of the column, the bearing bears an extra pressure, and there will be greater vibration when the equipment is in operation. Needle roller bearings with thicker outer rings that can withstand greater vibration are ge...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the installation is too cumbersome. The specific performance is: 1. Since the four positioning bolts are not located directly above the bearing, the installation and adjustment are difficult and time-consuming, and ultimately it is still impossible to avoid the deflection of the bearing's bearing posture; 2. Due to the use of large bearings, The installation space is wasteful; 3. Due to the cumbersome installation, it is almost impossible to use multiple bearings on the same rolling position at the same time
