Specific embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
Body implementation method is described in further detail to the utility model.
As shown in figure 1, in-pile instrument thimble assembly gripping tool includes：Hanger；Hook is grabbed, and it is connected with the hanger；On
Portion's sleeve assembly and lower sleeve portion component, it is each connected with the hanger respectively；Coupling sleeve, itself and the upper sleeve component
Connection；And top control stick and bottom control stick, it is connected with the hook, is configured to operate the hook.The hook
There are two pairs, and two hooks of each pair are symmetrical arranged.The hook is connected by academic title's axle with the hanger, is configured to crawl
IITA.The upper sleeve component and lower sleeve portion component are connected by screw with the hanger respectively.The coupling sleeve passes through
Screw thread is connected with the upper sleeve component.In-pile instrument thimble assembly gripping tool also includes boatswain chair component, and it passes through screw thread
It is connected with the coupling sleeve.
1. the structure and function of equipment
The gripping tool of the present embodiment is mainly grabbed by hook, hanger, top and the bottom control stick, top and the bottom sleeve assembly, coupling sleeve,
The compositions such as the positioning such as top cover cylinder, self-lubricating parts, spring, position fixing handle, boatswain chair component and supporting connector.Hook has grabbed two
It is right, it is in a symmetrical arrangement, it is connected on hanger by support shaft, for capturing IITA.Hanger, lower sleeve portion component, upper sleeve
It is connected by screw between component, is connected by screw thread between upper sleeve component, coupling sleeve, boatswain chair component.What is be connected into is whole
Body constitutes the path for carrying lifting pulling force.The operation that hook is grabbed is performed by sliding block, top and the bottom control stick, slide bar, position fixing handle,
Each part is connected by fast locking plug.
2. the operation of equipment with use
Position fixing handle is in open configuration first, insert fastening screw.Hung using ring and gripping tool is navigated to IITA
Top, by outside picture pick-up device, slowly makes downwards gripping tool navigate to IITA gripping heads position, it is ensured that four hooks are grabbed can be with
IITA gripping heads are completely covered.Unclamp fastening screw, position fixing handle under the action of the spring, drive top control stick, slide bar, under
Portion's control stick and sliding block form hook grabs overall control member and is up lifted, and sliding block is lifted to hook promptly state, insertion positioning
