Vertical guide structure of saw frame of stone sawing machine

Abstract

A vertical guide structure of a saw frame of a stone sawing machine comprises a top frame arranged between a front vertical column and a rear vertical column. The saw frame is positioned below the top frame and provided with a plurality of saw blades, a transmission mechanism capable of driving the saw frame to vertically move back and forth is arranged at the top of the top frame, and vertical guide mechanisms for guiding and buffering vertically back-and-forth movement of the saw frame are arranged on the lower portions of two sides of the saw frame. Each vertical guide mechanism comprises a piston seat and a piston rod, each piston seat is fixed to the bottom of the corresponding vertical guide mechanism, one end of each piston rod is fixed to two sides of the saw frame, the other end of each piston rod penetrates into the corresponding piston seat and is vertically and slidably connected with the piston seat, the piston seats are pneumatic piston seats or hydraulic piston seats, the front vertical column and the rear vertical column extend into or are embedded into the ground and are fixed to a foundation, and the piston seats are fixed to the foundation. The vertical guide mechanisms are capable of guiding and buffering vertically back-and-forth movement of the saw frame, impact damage to the top frame caused by vertically back-and-forth movement of the saw frame is avoided, and the stone sawing effect of the stone sawing machine is further ensured.

Description

Technical field [0001] The invention relates to a stone saw, in particular to a vertical guiding structure of a saw frame of a stone saw. Background technique [0002] I disclosed a main shaft structure of a large stone sawing machine in Chinese Patent Document No. CN102172987A on September 7, 2011. The large stone sawing machine includes a saw frame slidably arranged up and down between a front column and a rear column. There are a number of saw blades / blades; the main transmission structure includes a main shaft connected with the saw frame, and the main shaft is connected with a driving motor; the main shaft is connected with the saw frame through an eccentric block and a connecting rod. The left and right sides of the saw frame are respectively connected by a main shaft and a drive motor; the rotation speed of the two main shafts is the same. The main shaft is driven by the eccentric block and connecting rod and the saw frame to realize the up and down movement of the saw fr...

AI Technical Summary

Problems solved by technology

However, due to the use of belt transmission in its transmission structure, its volume is relatively large, which is not convenient for daily maintenance. At the same time, the stone saw machine occupies a large area. After long-term use, the wear of the left and right belts is inconsistent, which affects the consistency of its speed.
