Description

technical field [0001] The invention relates to a combination tensioning device and a tensioning method of a steel wire rope tank road, which is especially suitable for tensioning the steel wire rope of an ultra-deep vertical shaft tank road, and can also be used in other flexible tank road tensioning occasions. Background technique [0002] At present, there are mainly two kinds of tank road devices for the hoisting container of the coal mine hoist in my country: rigid combined tank and steel wire rope tank. With the deep mining of coal mines, the rigid combined tank is difficult to maintain due to its high investment cost and deformation. And other shortcomings, gradually replaced by steel wire rope tanks. Since the steel wire rope is a flexible material, the wide use of steel wire rope tanks will inevitably bring about the problem of tensioning the tank ropes. The known methods that can effectively provide tension for the tank ropes mainly include heavy hammer tensioning a...

Problems solved by technology

[0003] Hammer type tensioning usually installs a weight at the lower part of the tank rope, and uses the gravity of the counterweight to provide tension for the tank rope. Although the tension is relatively stable, as the tension increases, the weight of the hammer will As the volume is getting larger and larger, it is necessary to dig a larger water pit at the bottom of the well to place the heavy hammer, and the heavy hammer is easy to fall into the bottom of the well. Once a problem occurs, it is difficult to maintain and delay production; hydraulic cylinders are often installed on the derrick , provide tension force for the steel wire rope by lifting the clamping rope device. Although this method can better adjust the tension force of the tank road rope, but with deep well mining, the device is installed on the well, and the hydraulic cylinder has to withstand thousands of meters of steel wire rope. Weight, but also to provide more and more tension, the cost increases sharply, and the large volume of the hydraulic station brings difficulties to its layout

[0004] According to the above analysis, none of the existing tensioning devices can meet the current and future needs
