The invention provides a packing box pressure cover hanger. The packing box pressure cover hanger comprises a first hook portion, a body and a second hook portion. The first hook portion is used for hanging the packing box pressure cover hanger onto a beam hanger and connected to a first end of the body, and the second hook portion is connected to a second end of the body to hook a packing box pressure cover. By matching of the specially designed first hook portion, the body and the second hook portion, steadiness in hanging of the packing box pressure cover is realized, the problem of shedding of the pressure cover due to use of a simple iron wire tool in practical operation is avoided, and accordingly potential safety hazards are reduced.
Description
technical field [0001] The invention relates to the field of auxiliary tools for oil exploitation, in particular to a packing box gland hanger. Background technique [0002] Replacing the sealing packing of the pumping well is one of the daily maintenance work of the oil production workers on the pumping well. [0003] Since the on-site employees do not have a special suspension device to hang the gland and cap of the packing box during the operation of replacing the sealing packing, most of the staff use iron wire or simple hooks to hang the gland and cap. First, there are thick and thin, and some iron wires are prone to corrosion and fracture after a long time of use, causing the gland and cap to slip and hurt people, and there are serious safety hazards. Contents of the invention [0004] The main purpose of the present invention is to provide a packing box gland hanger which is convenient for stably suspending the packing box gland. [0005] In order to achieve the a...
