Description
Technical field
The present invention relates to the steel pins that one kind can eliminate hole, belong to the pin joint technical field of engineering structure or mechanical part.
Background technique
Pin joint is a kind of common force transferring structure form, has the characteristics that structure is simple, power transmission is clear and install convenient,
It is widely used in engineering structure and mechanical engineering.In Practical Project, it can be reserved to be easily installed, between pin shaft and pin hole certain
Hole, and the presence of hole often adversely affects structure.Speed is repaired to improve, for the equipment of emergency first-aid repair,
Such as each component connecting portion of type-64 military beam, 321 steel bridges, ZB200 steel bridge is all made of pin joint mode, and hole can make
Structure generates non-resilient displacement, and then internal force and deformation is caused to increase, and influences the normal use of structure.The pin joint structure of certain machinery
Part is often in harsh environments or bears complicated alternate load effect, and unbalance loading caused by hole will increase part and answer
Power aggravates structural vibration, shortens the service life of component substantially.In addition, many machine components are in processing and checkout procedure
The case where being positioned with hole can be encountered, positioning method generally uses alignment pin, and alignment pin and the fit clearance in hole are often
It will lead to installation error.
Summary of the invention
That technical problem to be solved by the invention is to provide a kind of structures is simple, power transmission is clear and install convenient is eliminated
The steel pin of hole.
The present invention adopts the following technical scheme:
The present invention includes columned steel pin body, rest pad, tension rod and caging bolt；It is arranged at steel pin body both ends and presses
Tight device；Axis hole A is axially set in the middle part of steel pin body, the axis hole B coaxial with axis hole A is set in the middle part of rest pad；The steel pin body
Including annulate shaft to the steel pin block for being uniformly arranged and be in three equal parts or more, each steel pin block is two at the top of from the both ends axis hole A to steel pin block
End is inclined to set；The slope of the steel pin block is identical as the outer draft of rest pad, and the inclined-plane and branch of the steel pin block
Limiting and guiding device is correspondingly arranged between supporting block outer wall；The rest pad is round estrade comprising the left bearing being symmetrical set
Block and right rest pad, the left rest pad and right rest pad are inserted into respectively in the round platform hole in steel pin body two sides, in the axis
The installation tension rod in hole A and axis hole B, in the tension rod both ends installation and adjustment nut；The caging bolt respectively corresponds
It is mounted on the outside of left rest pad and right rest pad end, caging bolt top is greater than with the vertical range of tensioning rod axis wait connect
The pin hole radius at place.
Steel pin block of the present invention is 4 pieces, and annulate shaft is to being uniformly arranged.
Limiting and guiding device of the present invention includes the keyway being arranged on each inclined surface of steel pin block and is separately fixed at
The flat key inserted on left rest pad and right rest pad outer wall with the matching of corresponding keyway.
Pressing device of the present invention includes that the annular groove at steel pin body both ends is arranged in and is arranged in annular groove subsidiary
The elastic ring of pretightning force.
The present invention is respectively set threaded hole on the outboard end of the left rest pad and right rest pad, the caging bolt with
Threaded hole is threadedly coupled, and connection chain is arranged at the top of the caging bolt, the connection chain other end is connect with steel pin block end.
Washer is arranged between adjusting nut and rest pad end in the present invention.
When adjusting nut of the present invention unclamps, under the effect of elastic ring pretightning force, each steel pin interblock gap is eliminated to be stablized in one
Structure, its outer diameter is Φ at this time1, outer diameter Φ1Less than the pin hole internal diameter of pending connection positionφ, this state is steel pin Reserve State.
The present invention tightens the adjusting nut of the steel pin body under Reserve State, using the pretightning force of adjusting nut by Zuo Zhicheng
Block and right rest pad inwardly squeeze, and squeezing action circumferentially struts each steel pin block, increase the external diameter Φ of steel pin i , pass through increasing
The external diameter Φ of big steel pin1The installation gap of steel pin body and pin hole is eliminated, as the external diameter Φ of steel pin i When increasing to use state
Outer diameter Φ2When stop force, Φ2WithφIt is equal.
When adjusting nut of the present invention is tightened, caging bolt inwardly moves closer to steel pin block side with left rest pad and right rest pad
Edge, as the external diameter Φ of steel pin i It is increased to Φ2When, caging bolt and steel pin block end edge along being bonded, between steel pin body and pin hole between
Gap is eliminated.
The present invention, which tightens adjusting nut, makes the external diameter Φ of steel pin i Increase, it is right between the inclined-plane and rest pad outer wall of steel pin block
The relative position that limiting and guiding device can guarantee that the two is circumferential during steel pin body diameter increases should be arranged not change, keep away
Exempt from position when steel pin block bears external loads to shift.
Good effect of the present invention is as follows: elasticity adjusting circle of the present invention is rubber ring, and the internal diameter of elastic ring nature is less than ring
The outer diameter of connected in star, pretightning force can be applied to steel pin block by being installed in annular groove.When adjusting nut unclamps, in elastic ring
Under pretightning force effect, 4 steel pin interblock gaps are eliminated, and are integrally formed i.e. Reserve State, and steel pin outer diameter is Φ at this time1, outer diameter Φ1
Less than the pin hole internal diameter of pending connection positionφ, it is easily installed.In addition, elastic ring can be such that steel pin block is close to always with rest pad, to protect
Hold the good globality of the present invention.
The adjusting nut of steel pin body under Reserve State is tightened, using the pretightning force of adjusting nut by left rest pad and the right side
Rest pad inwardly squeezes, and squeezing action circumferentially struts 4 steel pin blocks, increases the external diameter of steel pin, external by increasing steel pin
Diameter eliminates the installation gap of steel pin and pin hole, can effectively avoid hole to the adverse effect of engineering structure and mechanical part etc..
The external diameter Φ of steel pin will be made by tightening adjusting nut i (Φ i For a variable, Φ under Reserve State i =Φ1, increase process
In be variable Φ i , Φ when increasing to use state i =Φ2) increase, it is correspondingly arranged between the inclined-plane and rest pad outer wall of steel pin block
The relative position that limiting and guiding device can guarantee that the two is circumferential during steel pin body diameter increases does not change, i.e. steel pin body
Gap is had between 4 steel pin blocks during diameter increases, if limited without limiting and guiding device, each steel pin in loading process
Block may rotate offset, guarantee that position is stablized when steel pin block bears external loads.
After caging bolt of the present invention is connect with threaded hole, the vertical range of top and tensioning rod axis is greater than to even
Place's pin hole radius is connect, because the displacement of steel pin caused by vibrating falls off, when caging bolt and steel pin when can prevent structure from bearing dynamic load
When body contacts, the gap of steel pin body and pin hole is eliminated just, can also be used as judging the foundation whether pin hole gap is eliminated；Washer can
It prevents adjusting nut from loosening, while avoiding damaging left rest pad and right rest pad in cinching process.
The configuration of the present invention is simple, install convenient, reliable performance.
