Specific embodiment
Understandable for enabling the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings and specifically real
The present invention is further detailed explanation to apply mode.
As shown in figure 1, in-pile instrument thimble assembly gripping tool includes：Hanger；Hook is grabbed, and it is connected with described hanger；On
Portion's sleeve assembly and lower sleeve portion assembly, it is each connected with described hanger respectively；Coupling sleeve, it is with described upper sleeve assembly
Connect；And top stick and bottom stick, it is connected with described hook, is configured to operate described hook.Described hook
There have to be two right, and two hooks of each pair are symmetrical arranged.Described hook is connected with described hanger by academic title's axle, is configured to capture
IITA.Described upper sleeve assembly and lower sleeve portion assembly are connected with described hanger by screw respectively.Described coupling sleeve passes through
Screw thread is connected with described upper sleeve assembly.In-pile instrument thimble assembly gripping tool also includes boatswain chair assembly, and it passes through screw thread
It is connected with described coupling sleeve.
1. the structure of equipment and function
The gripping tool of the present embodiment is mainly grabbed by hook, hanger, top and the bottom stick, top and the bottom sleeve assembly,.Connection
The compositions such as the positioning parts such as set, top cover cylinder, self-lubricating, spring, position fixing handle, boatswain chair assembly and supporting connector.Hook is grabbed
There have to be two right, in a symmetrical arrangement, is connected on hanger by support shaft, for capturing IITA.Hanger, lower sleeve portion assembly, top
Pass through screw between sleeve assembly to be connected, pass through screw thread between upper sleeve assembly, coupling sleeve, boatswain chair assembly and be connected.It is connected into
Be monolithically fabricated carry lifting pulling force path.The operation that hook is grabbed by slide block, top and the bottom stick, slide bar, position fixing handle Lai
Execution, each part is connected by fast locking plug.
2. the operation of equipment and use
Make position fixing handle be 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 make downwards gripping tool navigate to IITA gripping head position it is ensured that four hooks grab permissible
IITA gripping head is completely covered.Unclamp fastening screw, position fixing handle under the action of the spring, drive top stick, slide bar, under
Portion's stick and slide block formation hook are grabbed overall control member and are up lifted, and make slide block rise to hook promptly state, insertion positioning
