Abstract
The invention provides a fixed type expansion pull rod. The fixed type expansion pull rod comprises a pull rod core, a pull rod sleeve and a transition sleeve. A central axis hole for installing the pull rod core is formed in the axis of the pull rod sleeve. The central axis hole is divided into a matching cavity and a guiding cavity through a partition layer. The pull rod core is arranged in the central axis hole. One end of the pull rod core is sleeved with the transition sleeve. The transition sleeve is arranged in the matching cavity in an interference fit mode. A limiting nut is arranged at the end, outside the transition sleeve, of the pull rod core. A positioning hole used for the butt joint is formed in the bottom end of the pull rod sleeve. A butt joint groove used for clamping connection is formed in the upper end of the pull rod sleeve. The pull rod sleeve is sleeved with a fixing frame which is connected into the butt joint groove in a clamping mode. Bolts used for fixation are arranged on the fixing frame.
Description
Technical field
The present invention relates to hardware fitting field, particularly relate to a kind of fixed expansion pull bar.
Background technique
Expansion joint is the additional stress compensated because temperature difference or mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.Due to it as a kind of can the elastic compensation element of free-extension, the advantages such as reliable operation, functional, compact structure, have been widely used in the departments such as chemical industry, metallurgy, nuclear energy.But in cement industry, the expansion joint especially cement kiln preheaters used, needs to have the feature such as the little and axial expansion amount of high temperature resistant degree, axial installation dimension is large.And expansion joint general is in the market substantially all the Ω shape metal bellows structure of little wave height, the little pitch of waves, but the preparation process of such bellows limits the wall thickness of bellows, easy generation swelling red sandstone unstability, and make such expansion joint fragile and not easy-maintaining after damaging.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of fixed expansion pull bar, and it is reasonable in design, and structure is simple, solves the even outside of expansion pull bar unbalance stress in the process of balanced stress and connects unstable problem.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is to provide a kind of fixed expansion pull bar, comprises pull bar core, drag link sleeve and transition sleeve; The axle center of described drag link sleeve is provided with the central shaft hole for installing described pull bar core; Described central shaft hole is cut off layer and is divided into mating cavity and directed cavity; Described pull bar core is installed in described central shaft hole; One end of described pull bar core is set with described transition sleeve; Described transition sleeve is installed in described mating cavity in an interference fit; The end of the pull bar core outside described transition sleeve is provided with stop nut; The bottom of described drag link sleeve is also provided with the positioning hole for docking; The upper end of described drag link sleeve is also provided with the docking groove for clamping; Described drag link sleeve is also set with fixing frame; Described fixing frame is connected in described docking groove; Described fixing frame is also provided with for fixing bolt.
Preferably, the bottom of described pull bar core is also provided with the screw mouth for docking.
Preferably, described bolt is at least provided with four; The axis of described bolt is in the axial keeping parallelism of described pull bar core.
The invention has the beneficial effects as follows: a kind of fixed expansion pull bar is provided, its structure is simple, reasonable in design, realizes effective annexation by the pull bar core of docking, between pull bar core and drag link sleeve, carry out balanced stress by the linkage structure of transition simultaneously, reach work object.Also realize the fixing of its outside by the docking structure of outer installment, prevent from being shifted during work.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fixed expansion of the present invention pull bar;
In accompanying drawing, the mark of each parts is as follows: 1, pull bar core; 2, drag link sleeve; 3, transition sleeve; 4, insulating course; 5, directed cavity; 6, stop nut; 7, docking groove; 8, positioning hole; 9, fixing frame; 10, bolt.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to accompanying drawing 1, the embodiment of the present invention comprises:
A kind of fixed expansion pull bar, comprises pull bar core 1, drag link sleeve 2 and transition sleeve 3; The axle center of described drag link sleeve is provided with the central shaft hole for installing described pull bar core 1; Described central shaft hole is cut off layer 4 and is divided into mating cavity and directed cavity 5; Described pull bar core is installed in described central shaft hole; One end of described pull bar core 1 is set with described transition sleeve 3; Described transition sleeve 3 is installed in described mating cavity in an interference fit; The end of the pull bar core 1 outside described transition sleeve 3 is provided with stop nut 6; The bottom of described drag link sleeve 2 is also provided with the positioning hole 8 for docking.Described drag link sleeve is also set with fixing frame 9; Described fixing frame is connected in described docking groove; Described fixing frame is also provided with for fixing bolt 10.The bottom of described pull bar core 1 is also provided with the screw mouth for docking.Described bolt is at least provided with four; The axis of described bolt 10 is in the axial keeping parallelism of described pull bar core.During work, dock corresponding linkage structure by pull bar core 1, and installed by spacer shell 3 between pull bar core 1 and drag link sleeve 2, the problem that the difference because of force bearing point is too concentrated the stress that pull bar core and drag link sleeve cause can be avoided.This fixed expansion pull bar, its structure is simple, reasonable in design, realizes effective annexation by the pull bar core of docking, carrys out balanced stress simultaneously, reach work object between pull bar core and drag link sleeve by the linkage structure of transition.Also realize the fixing of its outside by the docking structure of outer installment, prevent from being shifted during work.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
