Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed the syndeton of a kind of dismounting and hydraulic breaking hammer cylinder body easy for installation.
The purpose of the utility model can realize through following technical proposal:
The syndeton of this hydraulic breaking hammer cylinder body; Hydraulic breaking hammer comprises cylinder, middle cylinder and upper cylinder half, the piston that is positioned at cylinder body and drill steel down; The inside of cylinder during described piston is installed in; Described drill steel be positioned at following cylinder interior and be positioned at piston under; It is characterized in that, this syndeton comprises the connecting hole one be located on the upper cylinder half, be located on the cylinder with the connecting hole two of connecting hole one corresponding setting, be located at down on the cylinder with the connecting hole three of connecting hole two corresponding settings and can be inserted into the bolt in connecting hole one, connecting hole two and the connecting hole three, described bolt is threaded with above-mentioned connecting hole three.
The syndeton of this hydraulic breaking hammer cylinder body is inserted into bolt in connecting hole one, connecting hole two and the connecting hole three when connecting successively, and swivel bolt makes bolt be threaded with connecting hole three, reaches following cylinder, middle cylinder and upper cylinder half purpose of connecting.
In the syndeton of above-mentioned hydraulic breaking hammer cylinder body, described connecting hole one is located in the bottom of upper cylinder half, and when described bolt was inserted in connecting hole one, connecting hole two and the connecting hole three, the bar head of said bolt was resisted against the bottom of upper cylinder half.
The bar head of bolt is exposed on the external, can conveniently carries out installation and removal it.
In the syndeton of above-mentioned hydraulic breaking hammer cylinder body, described connecting hole three is an internal thread hole.
Following cylinder type of attachment is connected with nut by stay bolt and changes stay bolt into and directly be connected with following cylinder, and connecting hole three is arranged to internal thread, has improved the intensity of the weakness of time cylinder greatly.
In the syndeton of above-mentioned hydraulic breaking hammer cylinder body, described connecting hole one is an even number, and is evenly distributed on the bottom of upper cylinder half.The purpose that is provided with like this is, can make down cylinder, middle cylinder be connected more firm with upper cylinder half.
In the syndeton of above-mentioned hydraulic breaking hammer cylinder body, described connecting hole one is 4.Because the shape of upper cylinder half bottom is square, thus the quantity of connecting hole one is arranged to 4, and connecting hole one lays respectively at four jiaos of the upper cylinder half bottom.
Compared with prior art, the syndeton of this hydraulic breaking hammer cylinder body has the following advantages: following cylinder type of attachment is connected with nut by stay bolt and changes stay bolt into and directly be connected with following cylinder, has improved the intensity of the weakness of time cylinder greatly; Comparatively convenient when installation and removal, connecting hole one is 4, that is to say that 4 bolts link together upper cylinder half, middle cylinder and following cylinder, and syndeton is firm, and following cylinder can not rupture unusually; Owing to do not adopt nut, reduced cost.
Description of drawings
Fig. 1 is the structural representation of this hydraulic breaking hammer.
Fig. 2 is the partial sectional view of this hydraulic breaking hammer.
Among the figure, 1, following cylinder; 11, connecting hole three; 2, middle cylinder; 21, connecting hole two; 3, upper cylinder half; 31, connecting hole one; 4, drill steel; 5, bolt.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1, this hydraulic breaking hammer comprises down cylinder 1, middle cylinder 2 and upper cylinder half 3, the piston that is positioned at cylinder body and drill steel 4, the inside of cylinder 2 during piston is installed in, drill steel 4 be positioned at cylinder 1 inside down and be positioned at piston under.
