Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a tensioning device for a diamond wire saw machine. Background Art

[0002] A diamond wire saw is a cutting tool that uses a diamond wire as a saw chain. It is widely used in the construction and stone processing industries. The working principle of a diamond wire saw is to use the diamond particles on the diamond wire to cut hard materials. It has the advantages of high cutting efficiency, high precision, low noise, and easy operation, and has been widely used. However, in the process of using a diamond wire saw, due to long-term work and high-frequency vibration, the diamond wire may relax, resulting in a decrease in cutting effect or a slowdown in cutting speed. Therefore, in order to ensure the tension and cutting effect of the diamond wire, the diamond wire saw needs to be equipped with a tensioning device. The tensioning device can help the wire saw maintain an appropriate tension to ensure that the diamond wire saw chain does not shake, loosen or curl during high-speed operation, thereby ensuring the stability and efficiency of the cutting.

[0003] For this purpose, the utility model patent with the publication number CN208546166U discloses a tensioning device for a diamond wire saw machine used in mining, comprising a base plate, a slide plate slidably connected to the base plate is provided on the upper side of the base plate, a first fixed block fixedly connected to the base plate is inserted on the front side of the base plate, a threaded rod threadedly connected to the base plate is penetrated on the front side of the first fixed block, one end of the threaded rod is rotatably connected to one side of the slide plate, a plurality of shock absorbing devices are symmetrically provided on both sides of the base plate, two fixed plates symmetrically connected to the base plate are provided on the upper side of the slide plate, and pull rods slidably connected to the base plate are penetrated in the horizontal direction of the fixed plates. The advantage of the utility model is that a moving device is added to the diamond wire saw machine, and the diamond wire saw machine is driven to move on the base plate through a threaded transmission. When the tension of the diamond wire saw machine is insufficient, the threaded rod is rotated to adjust the tension of the diamond wire saw machine, thereby improving the mining efficiency of the ore.

[0004] However, this patent always requires manual adjustment when the tension of the diamond wire saw machine is insufficient after long-term use, and the tension of the diamond wire saw machine will change slowly with the working time, and manual adjustment may not be possible in time. Utility Model Content

[0005] The purpose of the utility model is to provide a tensioning device for a diamond wire saw machine in view of the above-mentioned deficiencies in the prior art, which can automatically adjust a certain degree of tightness, effectively reduce the number of manual adjustments, and improve efficiency.

[0006] The technical solution adopted by the utility model is a tensioning device for a diamond wire saw machine, comprising a fixed column, which is a hollow structure, a movable column is sleeved inside the fixed column, a lifting device is arranged inside the fixed column and the movable column, the movable column is slidably connected with the fixed column through the lifting device, a blind hole is opened at the top of the movable column, a telescopic column is arranged in the blind hole, a spring is sleeved on the surface of the telescopic column, one end of the spring is fixedly connected to the top of the movable column, and the other end is fixedly connected to a disc, the disc is fixedly installed on the top of the movable column, a fixed block is fixedly installed on the top of the disc, a groove is opened in the fixed block, and a fixing device is arranged in the groove.

[0007] Preferably, the lifting device includes a threaded hole, which is opened in the movable column. A threaded rod is threadedly connected to the threaded hole. A worm gear is provided at the bottom of the threaded rod and is integrally formed with the threaded rod. The bottom end of the worm gear is rotatably connected to the fixed column. A worm is rotatably connected to one side of the worm gear. One end of the worm gear passes through the fixed column and is fixedly installed with a grip column. The other end of the worm gear is rotatably connected to the fixed column.

[0008] Preferably, the fixing device includes a handle, one end of which is fixedly connected to a cylinder, one end of which passes through the fixing block and enters the groove, one end surface of the cylinder located in the groove is provided with a left thread, and the other end is provided with a right thread, and clamps are threadedly connected on the left and right thread surfaces.

[0009] Preferably, the sharp parts of the tops of the fixed column and the movable column are both rounded.

[0010] Preferably, mounting blocks integrally formed with the fixing column are provided at the four corners of the bottom of the fixing column, and mounting holes are provided on the surfaces of the plurality of mounting blocks.

[0011] Preferably, a protective cover is provided on the surface of the grip column.

[0012] The utility model is simple and convenient to use. It only needs to install the device in a suitable place by setting fixing tools such as bolts in the installation hole, and then place the diamond rope in the clamp and hold the column handle to rotate. The rotation of the handle will drive the cylinder to rotate, and the rotation of the cylinder will cause the left thread and the right thread to rotate. The rotation of the left thread and the right thread will drive the clamps on the surface to approach each other, so that the clamp clamps the column diamond rope. When the diamond rope needs to be tensioned, it only needs to hold the grip column and rotate it. The rotation of the grip column will drive the worm to rotate, and the rotation of the worm will drive the worm wheel to rotate. The rotation of the worm wheel will drive the threaded rod to rotate in the threaded hole, and then push the movable column to move upward. The upward movement of the movable column will push the clamp to move, and then lift the diamond rope and press down the spring, so as to increase the distance between the two points of the diamond rope and increase the tension of the diamond rope. The pressed spring will always press against the disc. When the tension of the diamond rope decreases, the spring will press against the disc to drive the telescopic column to rise, so as to compensate for the decreased tension and keep the diamond rope at a suitable tension.

[0013] Compared with the prior art, the utility model has the beneficial effect that after the tension of the diamond rope is adjusted to a suitable level, the tension of the diamond rope can be maintained, which can effectively avoid the need for frequent adjustments by manpower, effectively save time and improve efficiency.
