Background

Pulleys are a type of small tool widely used in lifting and handling, and are classified into load-bearing pulleys and insulating pulleys in electric power operations, wherein the insulating pulleys are all-insulated or partially-insulated tools used for rope guiding or bearing loads in live working. The alternating current withstand voltage test adopts equipment with the measuring range not smaller than 50kV alternating current withstand voltage test device, high voltage output by the device is introduced into the middle shaft of the insulating pulley, and after the high voltage reaches a test withstand voltage value, the high voltage is maintained for 60 seconds, so that the withstand voltage test is completed. When the high-voltage lead is led into the middle shaft of the insulating pulley, because the design and manufacturing process of the insulating pulley is different, the distance between the bolt at the middle shaft of the pulley and the guard plate is limited, three modes of 'loosening the bolt by two adjustable wrenches, winding the high-voltage wire and then compacting the bolt', 'not loosening the bolt and directly winding the high-voltage wire', and 'not loosening the bolt and fixing the high-voltage wire after winding by using crocodile clamps' are generally adopted. But all three access modes have drawbacks. The first mode is time-consuming and labor-consuming, the second mode has a large potential safety hazard, and the danger of falling off of the high-voltage lead wire exists. In the third mode, although the risk of falling off of the high-voltage wire is reduced, the diameters of the middle shafts and the bolts of insulating pulleys with different loads are greatly different, and for some insulating pulleys with larger rated loads (such as 5T), the bolts and the high-voltage lead wires cannot be clamped by the existing crocodile clips.

It will be further understood that when interpreting the connection or positional relationship of elements, although not explicitly described, the connection and positional relationship are to be interpreted as including the range of errors that should be within an acceptable range of deviations from the particular values as determined by those skilled in the art. For example, "about," "approximately," or "substantially" may mean within one or more standard deviations, and is not limited herein.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
