Embodiment Construction
[0045] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.
[0046] In this embodiment of the application, the "front" and "rear" referred to are based on the front and rear shown in the drawings; "first end" and "second end" are opposite ends.
[0047] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0048] The buckle is connected to the mounting surface by nailing, and is used to strengthen the connection or increase the pressure of the sealing part. The clasp is tightly connected to the installation surface by being pressed on the installation surface, and is connected with the installation surface through the auxiliary connection of the fastener. Optionally, whe...

The invention relates to a retaining ring dismounting device and a retaining ring dismounting method, and relates to the field of oil extraction machine equipment tools. The retaining ring dismounting device comprises a rocker assembly, a shell, a transmission assembly, a fixing assembly and at least one hook assembly; the rocker assembly is located at n the top of the shell; a sleeving assembly is movably connected with the shell; a base is located at the bottom of the shell; and each hook assembly comprises at least one hook. Under the condition that the rocker assembly is stressed to rotate, the trend of mutual movement is generated between the base and the mounting surface, then the interaction force between the base and the mounting surface is formed, each hook assembly receives the acting force in the same direction through conduction of the base, and finally, a retaining ring falls off. The retaining ring dismounting device is fixed through the fixing assembly, the force is transmitted between the rocker assembly and the transmission assembly, finally, the retaining ring is separated from the mounting surface under the acting force of the hooks, in the dismounting process, a user only needs to rotate the rocker, the dangerous phenomenon is not likely to be caused, and the safety is high.
Description
technical field [0001] The present application relates to the field of oil extraction machine equipment and tools, and in particular to a buckle removal device and a buckle removal method. Background technique [0002] Oil extraction machine is a common large-scale oil extraction equipment in the petroleum industry. In the oil extraction machine, it includes a crank mechanism and a connecting rod mechanism. The connecting rod mechanism is connected to the crank pin of the crank mechanism, and a clasp is arranged on the crank pin, and the clasp is used for fixing the crank pin, so that the crank mechanism and the connecting rod mechanism are stably connected. [0003] When the crank mechanism and the connecting rod mechanism need to be disconnected due to equipment maintenance, pin replacement, etc., it is necessary to cooperate with two people. After fixing the connecting rod, insert an oblique iron into the gap between the buckle and the crank pin, and use a sledgehammer ...
