Description

Technical Field

[0001] The utility model relates to the technical field of operating machinery, in particular to a valve installation accessory and an operating machinery. Background Art

[0002] In the related art, when replacing valves in oil wells, it is usually necessary to use a crane to lift the valve and place it in the installation position, and finally fix the valve with threaded fasteners. However, during the installation of the valve, the well body or pipeline may spray gas or liquid and other fluids outward, and the valve is not easy to dock or fit with the installation position under the action of the fluid pressure, resulting in greater installation difficulty.

[0003] In order to solve the above problems, a valve installation accessory is provided in the related art, including a support, a connecting plate and an elastic member. The support is used to connect with the mechanical arm of the excavator, and a supporting structure for supporting the connecting plate is provided on the support, and the connecting plate can move away from or close to the supporting structure. The two ends of the elastic member are respectively connected to the support and the connecting plate, and are used to drive the connecting plate to abut against the supporting structure. The connecting plate is used to connect with the valve.

[0004] During use, the excavator's mechanical arm places the valve in the installation position through the valve installation attachment, and the mechanical arm prevents the valve from being inconvenient to fit the installation position under the action of fluid pressure. The elastic part can buffer the impact between the valve and the installation position during the installation process.

[0005] Although the valve installation fittings in the above-mentioned related art can install the valve, the elastic member cannot limit the connection plate laterally, so that the connection plate can slide on the supporting structure. Therefore, during the installation process, when the support tilts and causes the valve to move laterally, or when the installation position and the valve interact and cause the valve to move laterally, the connection plate cannot limit the valve, which easily leads to the problem that the valve is not easy to align with the installation position.
