The invention discloses a nondestructive rapid anchoring device for a dyneema rope and an operation method of the nondestructive rapid anchoring device. The nondestructive rapid anchoring device comprises winding discs and a fixing shaft, wherein the fixing shaft penetrates through the centers of the winding discs; the fixing shaft is fixedly connected with the plurality of winding discs; a space between every two winding discs is used for winding the dyneema rope; a locking pin is arranged at a position, close to the fixing shaft, of each winding disc; the locking pins are detachably connected with the corresponding winding discs; each locking pin penetrates through the corresponding winding disc. The operation method of the nondestructive rapid anchoring device, disclosed by the invention, adopts a dyneema rope self-laminated locking mode, and a traditional clamping mode is changed, so that the possibility that the dyneema rope is damaged is reduced; in addition, the operation method is convenient in operation; a rapid rotating mode is adopted in a whole process; compared with a traditional bolt pressing mode, the operation method disclosed by the invention has the advantage that the efficiency is greatly improved.

A belt type fastening device comprises a shell part with a first fixing surface, a fastening component comprising a head portion and a rod portion, a nut part and a flexible belt, wherein at least part of the rod portion in length is provided with an outer thread; the nut part comprises a threaded hole with an inner thread; the nut part is installed on the rod portion through thread matching; the flexible belt is provided with a first end and a free end; the first end is connected with the nut part; the fastening component further comprises a second fixing surface; one part of the flexible belt is arranged between the first fixing surface and the second fixing surface; the rod portion of the fastening component rotates in one direction, so that the nut part moves towards the head portion of the fastening component along the rod portion, the second fixing surface moves towards the first fixing surface, and therefore one part of the flexible belt abuts against and is fixedly positioned on the first fixing surface.

The invention discloses a high-tension cable de-icing machine which comprises a split type box. A de-icing high-tension cable penetrates through the box along a semicircular hole, a de-icing mechanism is arranged at one end of the box, and the de-icing mechanism comprises a geared motor, a driving gear and a driven gear, wherein the driving gear and the driven gear are meshed with each other. The driven gear is formed by combining two semicircular gears, and tools are arranged on the end face of the driven gear. A walking driving mechanism and a gear motor are arranged in the box, and an output shaft of the gear motor is connected with driving chain wheels and driven chain wheels through chains. Each driven chain path shaft is sleeved with a polyurethane wheel, and the polyurethane wheels are pressed on the high-tension cable to be de-iced to move forward in a rolling mode along the cable. The high-tension cable de-icing machine further comprises remote video collecting equipment, a lifting mechanism and a pressurizing mechanism. After the de-icing machine is hung on the cable through an insulating rod, a lower box body is driven by the lifting mechanism to be combined together with an upper box body, and the box can achieve the function of fixing other parts and the function of supporting. The de-icing machine is compact in structure, small in size, low in weight and suitable for working high above the ground.
