Description
Technical field
The utility model relates to the jack in prestressing force applied technical field, in particular to the preceding card of a kind of Fast Installation
Jack.
Background technique
Preceding card jack used at present, piston need to be attached with tool anchor slab with screw thread, and when construction need to be by tool
Anchor slab constantly rotate piston and tool anchor slab could be installed to position；Equally, it is also to use to be threadedly coupled that top plate is covered with top plate
Structure, when construction, which is also required to continuous rotating top plate, can just be installed in place；Since the weight of tool anchor slab, top plate is big, it is not easy to
Rotation, therefore, constructional difficulties are time-consuming and laborious；In addition, the groove of used tool clamping piece and baffle fit is that equal diameter is recessed
Slot, intensity is low, and durability is poor.
Utility model content
The purpose of this utility model be just to provide it is a kind of facilitate construction, accelerate speed of application, structure is simple, and intermediate plate intensity is high
Fast Installation preceding card jack.
The solution of the utility model is such that
A kind of preceding card jack of Fast Installation, including oil cylinder, piston, sealing plate, support tube, automated tool anchor, tool
The front end inner hole of anchor slab, top plate, top plate set, the top plate set is tooth form, and tooth form rear end is provided with card slot；The top plate
Outer diameter is the external tooth matched with the front end inner hole tooth form that top plate covers, and tooth form of the top plate along top plate set front end is moved to groove position
When, rotating top plate is limited in top plate in card slot by top plate set teethed end faces.
More specific technical solution is also: the tooth form of the front end inner hole of the top plate set is plum blossom tooth form, the top plate
Outer diameter be plum blossom external tooth with matching.
Further: the front end inner hole of the piston is tooth form, and tooth form rear end is provided with card slot；The tool anchor slab
Outer diameter is the external tooth matched with piston inner hole tooth form, when tool anchor slab is moved to groove position along the tooth form of piston nose, rotation
It changes a job and has anchor slab, so that tool anchor slab is limited in card slot by piston teethed end faces.
Further: the tooth form of the piston nose inner hole is plum blossom tooth form, and the external tooth of the tool anchor slab is phase therewith
The plum blossom external tooth of cooperation.
Further: the lower groove band taper of the tool clamping piece, the small end of taper are located at the root of the first detent.
It is further: the second detent portion of protrusion is provided at the maximum taper of tool clamping piece lower groove.
It is further: to be corresponding taper hole with the hole for the baffle that tool clamping piece lower groove matches.
The utility model has the advantages that shift top plate onto bottom when construction along top plate set card slot direction, rotate by a certain angle,
Just it can guarantee automated tool anchor Fast Installation and move back anchor；Equally, tool anchor slab assembly shifts bottom onto along piston card slot direction, rotation
Certain angle is just able to achieve jack automated tool anchor Fast Installation；Tool clamping piece design is tapered, increases the strong of intermediate plate
Degree, improves the durability of intermediate plate；Constructing operation is simple, convenient, fast, works low, work efficiency is high.

Specific embodiment
As shown in Figure 1, 2, the front end inner hole of top plate set 7 described in the utility model is tooth form E, is arranged in the rear end tooth form E
There is card slot D；The outer diameter of the top plate 6 is the external tooth F matched with the front end inner hole tooth form of top plate set 7, and top plate 6 is along top plate set 7
When the tooth form E of front end is moved to the position of card slot D, rotating top plate 6, so that top plate 6, which covers 7 teethed end faces by top plate, is limited in card slot
In D；Wherein the tooth form E of the front end inner hole of top plate set 7 is plum blossom tooth form, and the outer diameter F of the top plate 6 is plum blossom with matching
External tooth.
The front end inner hole of piston 2 is tooth form B, and tooth form rear end is provided with card slot A；The outer diameter of the tool anchor slab 14 be with
The external tooth C that 2 inner hole tooth form of piston matches, when tool anchor slab 14 is moved to the position of card slot A along the tooth form of piston nose, rotation
