Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum maintenance tools, and in particular relates to a maintenance fixture for a glue injection gun. Background Art

[0002] SAGD oil wells use glue-injected sealing packing boxes. When replacing the rod sealing packing, it is necessary to use a hydraulic glue-injection gun to inject glue into the lower part of the packing box to seal the rod. The glue-injection gun is used frequently and often gets damaged. Therefore, it is necessary to disassemble and assemble the glue-injection gun for inspection to ensure that the glue-injection gun can be used normally.

[0003] Since there are no special tools for glue gun maintenance, the installation of glue gun requires multiple people to use supports to clamp the glue gun and then manually compress the reset spring. Due to the shaking of the glue gun, it is difficult to buckle the pressure cover. In the case of a small number of people, the glue gun maintenance cannot be completed, which affects the replacement of packing in the oil well. In addition, manual disassembly and assembly of the reset spring of the glue gun has certain safety risks, and the reset spring is prone to pop out and injure people. Developing a mechanical compression tool to improve the maintenance efficiency of the glue gun and reduce the safety risks of manual disassembly and assembly of the glue gun is an effective way to solve the current glue gun maintenance. Through patent search, it was found that there is a "Tool for disassembly and assembly of glue guns with pressure plugging" (utility model patent CN201821492829.8; utility model patent CN201811066697.7. This patent adopts a cage structure and uses multiple screws to compress the glue gun spring. The cage structure is not convenient to install. During the maintenance process, the glue gun is located inside the disassembly and assembly tool. The operating space is limited, which is not convenient for disassembly and assembly of the glue gun.
