Description

Technical Field

[0001] The utility model relates to the technical field of positioning tools for rope saw machines, in particular to a rope saw machine with a positioning mechanism. Background Art

[0002] A wire saw is a device that uses the oil pressure of a hydraulic pump station to drive a hydraulic motor to rotate. The hydraulic motor converts the oil pressure into mechanical energy to drive the driving wheel to rotate. The driving wheel then cuts and removes reinforced concrete through the rotation of the rope. At the same time, the rope can rotate at high speed through the guidance control of the driven wheel, and the direction of the rope can be controlled. Therefore, the hydraulic wire saw can achieve various cutting of thicker concrete. This equipment is widely used in static cutting and removal of bridges, piers, dock platforms and underwater concrete piles, while ensuring that the original structure is not damaged. Existing wire saws generally cut objects by driving the rope to rotate through the driving wheel, but the wire saw needs to put the rope on the object at the beginning, and the rope is in a taut state at this time. However, during the cutting process, the wire saw needs to be moved to keep the rope in a taut state. When the wire saw can no longer move, the rope will change from a taut state to a loose state during cutting, thereby reducing the cutting efficiency. Therefore, improvements need to be made based on the above problems. Utility Model Content
