It is equipped with clamping screw；
The front end of described pulling device connects column pitman；
Column pitman is stepped, and point diameter is more than rear end diameter,
Screw-thread steel front end is inserted in abutment sleeve, and screw-thread steel is locked by clamping screw with positioning sleeve；
The location that location dish is inserted by the circular hole in 8 font lock muscle holes in the front end of the column pitman of described pulling device sinks
Hole.
The beneficial effect of this utility model hinge structure:
The pulling device of this utility model welding hybrid reinforcement prestressed pipe pile cages, by common tube pile seam welder one
Secondary screw-thread steel is welded complete with prestressed steel bar, simple in construction, easy to operate, reduce labor strength, improve work effect
Rate, it is ensured that welding quality.

Detailed description of the invention
Referring to the drawings and this utility model is described in detail by embodiment:
Accompanying drawing 1-5 understands, a kind of pulling device assembly welding hybrid reinforcement prestressed pipe pile cages, including: in advance should
Power rod iron, location dish 1 and lock muscle dish 2；Location dish 1 is connected with rotary shaft 3 by connecting bolt, is provided with inside lock muscle dish 2
Gland 4, gland 4 is connected with central shaft 5 by bolt；Central shaft 5 is fixing with rotary shaft 3 to be connected, and described location dish 1 is circumferentially
Direction is provided with location counterbore 6；
Peripherally disposed on described lock muscle dish 2 have 8 font lock muscle holes 7；
Described 8 font lock muscle holes 7 are made up of circular hole 71 and bar hole 72；
The front end of prestressed steel bar 8 is provided with heading 14；
Described heading 14 inserts the location counterbore 6 of location dish by the circular hole 71 in 8 font lock muscle holes 7；
Also including screw-thread steel 9, the front end of described screw-thread steel 8 connects pulling device 13；
Described pulling device includes that abutment sleeve 10, described abutment sleeve 10 sidewall are provided with locking hole, described locking hole
Inside it is provided with clamping screw 11；
The front end of described pulling device connects column pitman 12；
Column pitman 12 is stepped, and point diameter is more than rear end diameter,
Screw-thread steel 9 front end is inserted in abutment sleeve 10, and screw-thread steel 9 is locked by clamping screw 11 with positioning sleeve 10；
