Description
Technical Field
The utility model relates to the field of hydraulic techniques, in particular to trunnion formula pneumatic cylinder is with novel base structure.
Background
The hydraulic cylinder base is a device for fixing the hydraulic cylinder in a hydraulic system, the existing hydraulic cylinder base is an L-shaped base, and equipment hidden danger that the base is loosened frequently appears in the reciprocating motion process of the hydraulic cylinder for replacing the hydraulic cylinder conveniently and quickly. Especially in longitudinally moving hydraulic cylinder devices.
A pressure equalizing valve and a bleeding valve on the top of a bell-less blast furnace are important equipment for equalizing and bleeding of a charging bucket on the top of the blast furnace, and once a fault occurs, the blast furnace cannot discharge. The pneumatic cylinder that equalizer, diffuse valve used is trunnion formula longitudinal movement's pneumatic cylinder form, and the in-process is examined to the point at ordinary times, and the hidden danger that often appears is that pneumatic cylinder base bolt is not hard up, and in time discovery and then can cause the pneumatic cylinder crooked, and jar pole bending deformation causes equalizer, diffuse valve and can't close, and the unable blowing of blast furnace causes the use inconvenience.
SUMMERY OF THE UTILITY MODEL
In view of this, the application provides a novel base structure for trunnion formula pneumatic cylinder, has solved current "L type" base, and in the use, often appear that fixing bolt is not hard up, cause the pneumatic cylinder crooked, the crooked deformation of piston rod, the unusual equipment trouble of action execution.
For solving above technical problem, the utility model provides a technical scheme is a gudgeon formula pneumatic cylinder is with novel base structure, its characterized in that: including the base structure body, the base structure body include, base 1, bottom plate 2, wherein one side and bottom plate 2 one-tenth notch cuttype of base 1 are connected, the opposite side of base 1 sets up the riser perpendicularly, and central point puts on the riser and sets up trunnion hole 3, base 1 is a whole through welding or machining with bottom plate 2.
One of them trunnion formula pneumatic cylinder is with novel base structure, the symmetry sets up bolt hole I5 on bottom plate 2.
One of them trunnion formula pneumatic cylinder is with novel base structure, the symmetry sets up bolt hole II 4 on the base 1.
One of them trunnion formula pneumatic cylinder is with novel base structure, the thickness of the link of base 1 and bottom plate 2 is the twice of the thickness of bottom plate 2.
Compared with the prior art, the detailed description of the application is as follows:
1. the utility model discloses simple structure, it is convenient to use, convenient operation has improved work efficiency, the utility model discloses a base 1 and 2 lower surface parallel and levels of bottom plate, upper surface form the difference in height, form the notch cuttype structure. Base 1 and bottom plate 2 are equipped with bolt hole II 4, bolt hole I5 respectively on the surface, all fix with the disk seat through the fastener.
2. Traditional "L type" base compares, only two bolt fastening, the utility model discloses be the notch cuttype structure, through bolt hole II 4, bolt hole I5 can use four bolt fastening, the utility model discloses change single bolt fastening connection into the bolt assembly who receives transverse load and connect, after the bolt compresses tightly, produce the packing force at the faying face, assume that each bolt pretightning force equals, then each normal pressure equals, assume that each bolt department frictional force also equals, according to balanced condition, be the composition surface coefficient of friction in the formula, m is the composition surface logarithm, n is the bolt figure, for factor of safety, for the power that the bolt bore, the utility model discloses make bolt figure n increase, turn into bolt assembly with single bolt connection, and then reduce the power that the bolt bore to the fastness of base has been improved, played the effect that prevents not hard up.
2. Simultaneously, the difference in height of base 1 and bottom plate 2 can effectively release the impact to the base when pneumatic cylinder moves, avoids the base not hard up, and is practical reliable.
