Abstract

The utility model discloses connection fish tail long slab forging mold between a kind of column crane mast section, there is counterdie and patrix, counterdie and patrix are formed with fish tail long slab die cavity when being assembled into one, this fish tail long slab die cavity comprises hypomere connecting portion chamber and epimere clamping part chamber, described hypomere connecting portion chamber has connection plane, the position of described epimere clamping part chamber in described connection plane the same side and between this clamping part chamber roof to clamping part chamber roof is provided with actuate slopes, is formed with angle β between this actuate slopes and vertical plane.Apply the fish tail long slab of forging mold forging molding of the present utility model, connecting plane the same side and position between the clamping part top to clamping part top is formed with actuate slopes, the chamber formed when coordinating with fish platee has larger aperture in porch, make main chord of standard section be easy to be embedded in the chamber that formed between fish tail long slab and fish platee, the set-up time of standard knot can be saved.

Description

Connect between column crane mast section with fish tail long slab forging mold
Technical field
The utility model relates to connection fish tail long slab forging mold between a kind of column crane mast section.
Background technology
Tower machine is the crane gear being mainly used in building field, and along with increasing of depth of building, the working depth of tower machine also wants corresponding raising, and the working depth increasing tower machine realizes by increasing tower machine standard knot.Increase tower machine standard knot, first by jacking cylinder, the jacking of tower machine jacking joint is propped, then standard knot is moved into, main chord and the fish tail long slab on tower machine main chord of standard section and fish platee of the standard knot the moved into merga pass that matches is connected bearing pin fixing and locking, finally completes the installation of immigration standard knot and then the working depth of raising tower machine.
Connection fish tail long slab between column crane mast section of the prior art, there is fish tail long slab body, this fish tail long slab body comprises hypomere connecting portion for being connected with main chord of standard section and for clamping the epimere clamping part that upper saves main chord of standard section, described hypomere connecting portion has connection plane, described epimere clamping part has clamp circle disk, clamp circle disk has connecting pin bores, two tower machine standard knots are that the main chord of a upper standard knot is embedded in chamber that next main chord of standard section is formed between fish tail long slab and fish platee when connecting, again by connecting bearing pin fixing and locking.The chamber formed between fish tail long slab and fish platee matches with the shape and size of main chord, when increasing standard knot and improving tower machine working depth, it is comparatively difficult that main chord of standard section is inserted into the chamber formed between fish tail long slab and fish platee, need the waste long period just can complete, need to have comparatively skilled operator in addition and remove installation exercise.
Utility model content
The technical problems to be solved in the utility model is to provide connection fish tail long slab forging mold between a kind of column crane mast section, when increasing tower machine working depth and moving into standard knot, its main chord is easy to be embedded in the chamber that formed when the fish tail long slab of application forging mold forging of the present utility model and fish platee match.
For solving the problems of the technologies described above, connection fish tail long slab forging mold between column crane mast section of the present utility model, there is counterdie and patrix, counterdie and patrix are formed with fish tail long slab die cavity when being assembled into one, this fish tail long slab die cavity comprises hypomere connecting portion chamber and epimere clamping part chamber, described hypomere connecting portion chamber has connection plane, the position of described epimere clamping part chamber in described connection plane the same side and between this clamping part chamber roof to clamping part chamber roof is provided with actuate slopes, angle β is formed between this actuate slopes and vertical plane.
As improvement of the present utility model, the angle β formed between described actuate slopes and vertical plane is 25-35 °.
As further improvement of the utility model, the angle β formed between described actuate slopes and vertical plane is 30 °.
Adopting between the column crane mast section of said structure connects with fish tail long slab forging mold, because the position of described epimere clamping part chamber in described connection plane the same side and between this clamping part chamber roof to clamping part chamber roof is provided with actuate slopes, angle β is formed between this actuate slopes and vertical plane, therefore the fish tail long slab of forging mold forging molding of the present utility model is applied, connecting plane the same side and position between the clamping part top to clamping part top is also formed with actuate slopes, therefore when standard knot is installed, the chamber that fish tail long slab and fish platee are formed has larger aperture in porch, main chord of standard section is made to be easy to be embedded in the chamber that formed between fish tail long slab and fish platee, the set-up time of standard knot can be saved, require also lower to the qualification of operator.
Experiment proves that the angle β formed between described actuate slopes and vertical plane is 25-35 °, and the embedding of the convenient main chord of standard section of the chamber formed between the fish tail long slab forged and fish platee, angle β is preferably 30 °.

Detailed description of the invention
See Fig. 1, Fig. 2, connection fish tail long slab forging mold between column crane mast section of the present utility model, there is counterdie 1 and patrix 2, counterdie 1 and patrix 2 are formed with fish tail long slab die cavity 3 when being assembled into one, this fish tail long slab die cavity 3 comprises hypomere connecting portion chamber 4 and epimere clamping part chamber 5, described hypomere connecting portion chamber 4 has connection plane 6, the position of described epimere clamping part chamber 5 in described connection plane 6 the same side and between this clamping part chamber roof to clamping part chamber roof is provided with actuate slopes 7, angle β is formed between this actuate slopes 7 and vertical plane.
The angle β formed between described actuate slopes 7 and vertical plane is 25-35 °.
The angle β formed between described actuate slopes 7 and vertical plane is preferably 30 °.
