Abstract
The utility model discloses one and rush stake machine hammer tooth extracting apparatus, comprise opening fork and handle; The prong of described opening fork is that circular arc is in order to snap in the draw-in groove on hammer tooth external surface; Described handle one end is fixed in the middle part of after the prong of opening fork; Described handle and opening are pitched junction and are fixed with fore-set for withstanding the lower surface of hammer anvil; Described fore-set and opening are pitched two and are pitched the plane orthogonal that claw type becomes.Described fore-set is high is 3 ㎜.The prong of described opening fork is semicircle.Like this, be convenient to clamping hammer tooth, increase work efficiency.The cross section of described opening fork two fork pawl is circular.Like this, be convenient to clamping hammer tooth, increase work efficiency.Described fore-set is cylinder.
Description
Technical field
The utility model relates to one and rushes stake machine hammer tooth extracting apparatus.
Background technology
Rushing stake machine is a kind of conventional engineering machinery, and comprise hammer anvil, part such as hammer tooth, draw-gear etc., it impacts downwards by the hammer tooth being welded on hammer anvil lower end and stone in heatable adobe sleeping platform and hard object is crushed into powder, and then discharges outside hole.Wherein, hammering tooth into shape is an easily worn part.The hammer tooth of prior art is directly welded on hammer anvil lower end.Need to change immediately after hammer tooth damages.During replacing, need to hang on hammer anvil and remove damaged hammer tooth, polishing is repaired, the hammer tooth that repair welding is new.This Renewal process needs just can complete two working days, and weld a new hammer tooth and need more than 2,000 yuan of expense, often incur loss through delay the progress of engineering, change inconvenience, use cost is high, also affects operating efficiency.
If hammer facing is connected to hammer anvil, then can overcome the above-mentioned defect of prior art.But, if hammer facing is connected to hammer anvil, then need a kind of hammer tooth puller easy to use of specialty during dismounting.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to use machine that rushes and hammers a tooth extracting apparatus into shape.
In order to solve the problems of the technologies described above, punching stake machine hammer tooth extracting apparatus of the present utility model comprises opening fork and handle; The prong of described opening fork is that circular arc is in order to snap in the draw-in groove on hammer tooth external surface; Described handle one end is fixed in the middle part of after the prong of opening fork; Described handle and opening are pitched junction and are fixed with fore-set for withstanding the lower surface of hammer anvil; Described fore-set and opening are pitched two and are pitched the plane orthogonal that claw type becomes.
As preferably, described fore-set is high is 3 ㎜.
As preferably, the prong of described opening fork be semicircle.Like this, be convenient to clamping hammer tooth, increase work efficiency.
As preferably, the cross sections of described opening fork two fork pawls be circle.Like this, be convenient to clamping hammer tooth, increase work efficiency.
Described fore-set is cylinder.
Adopt structure of the present utility model, pitch and fore-set and handle owing to being provided with the opening adapted to the draw-in groove hammered into shape on tooth external surface, when needs dismounting hammer tooth, opening fork is entered to hammer into shape the draw-in groove on tooth external surface, and fore-set withstands the lower surface of hammer anvil, with this fore-set for fulcrum, upwards move handle, just can easily hammer tooth be extracted downwards from hammer tooth lock tube, convenient disassembly, time saving and energy saving.Adopt hammer tooth extracting apparatus of the present utility model, hammer tooth dismounting problem can be solved, thus the change hammering tooth and hammer anvil connected mode into shape can be realized.This manufacturing structure is simple, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model hammer tooth extracting apparatus;
Fig. 2 is the sectional view of the utility model hammer tooth extracting apparatus along A-A line.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1 and Figure 2, the utility model rushes stake machine hammer tooth extracting apparatus and comprises opening fork 1 and handle 3.The prong of opening fork is that circular arc is in order to snap in the draw-in groove on hammer tooth external surface.Handle one end is fixed in the middle part of after the prong of opening fork.Handle and opening are pitched junction and are fixed with fore-set 2 for withstanding the lower surface of hammer anvil, and fixed form is that prior art is as welding or riveted joint etc.Fore-set and opening are pitched two and are pitched the plane orthogonal that claw type becomes.
Fore-set height is preferably 3 ㎜.Differing heights can be selected as required.
The prong of opening fork is preferably semicircle.
The cross section of opening fork two fork pawl is preferably as circular.
Fore-set is preferably cylinder.
