Tensioning device of underwater diamond wire saw

Abstract

The invention discloses a tensioning device of an underwater diamond wire saw. The tensioning device comprises a support and a tensioning wheel. The tension device is characterized in that a tensioning mechanism comprises a left support and a right support, wherein the left support is fixed on the support, the right support is arranged on the support and slides relative to a left seat body, a drive disk is arranged on the end face of the left support, and a first magnet is arranged on the end face of the drive disk; a fixed disk, which corresponds to the drive disk, is arranged on one end of the right support, a corresponding second magnet is arranged on the end face of the fixed disk, a tensioning wheel shaft and the tensioning wheel are arranged on the other end of the right support, when the drive disk rotates, the first magnet rotates, the first magnet and the second magnet generate repulsive force and suction, so that the fixed disk and the tensioning wheel can move back and forth relative to the drive disk, thus the tensioning wheel is horizontally moved to realize tensioning adjustment of a beading strand. By adopting the magnetic tensioning mechanism, in comparison with the conventional mechanical tensioning mechanism, the tensioning device has no energy loss generated by the friction, the vibration and the noise are greatly reduced, and the tensioning device has the advantages of long service life of parts, capability of saving lubricant oil and quick adjustment.

Description

technical field [0001] The invention relates to the technical field of underwater diamond wire saw machines, in particular to a tensioning device for diamond wire saw machines. Background technique [0002] At present, in the field of cutting and processing of stone and submarine oil pipes, wire saw cutting machines have been widely used due to their own advantages. For the commonly used diamond wire saw machine, it usually includes a clamping mechanism and a cutting mechanism, wherein the cutting mechanism includes a cutting frame, a tensioning device, a main moving device, a radial feeding device and a guiding device, etc. The existing tensioning device is mainly composed of a tensioning wheel, a tensioning wheel shaft seat, an adjustment handle, a screw, and a base. The base is slidingly fitted with the tensioning wheel shaft seat. Pass through the tensioning wheel shaft seat to connect the adjustment handle, and the tensioning wheel shaft seat is provided with a tension...

Problems solved by technology

This structure that uses the rotation of the lead screw to generate tension will cause heat generation and energy loss due to friction, and the tension adjustment speed is slow

[0003] There is also the Chinese patent "A Wire Saw Machine Saw Rope Tensioning Device" with the patent number of 200820173477.X, which is composed of a motor, a driving wheel, a driven wheel, a saw rope and a support, and the driven wheel in the upper left corner is fixed on the telescopic oil cylinder. At one end, the other end of the telescopic oil cylinder is fixed on the bracket. There is a tensioning wheel in contact with each saw rope. The tensioning wheel is installed at one end of the tensioning telescopic oil cylinder between the two driven wheels on the same side. The other end of the oil cylinder is fixed on the bracket, and the two adjacent tensioning wheels are staggered up and down. This structure adjusts the tension of the saw rope through the expansion and contraction of the tensioning telescopic oil cylinder, so that the stone can be cut evenly. However, this structure requires the motor to rotate. Therefore, there are defects of high use cost and complex structure
