Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Present embodiment discloses a kind of standard section of tower crane, as shown in Figure 1, including four main strings vertically set
Bar 1, the oblique of two parallel cross bars 2 and two settings that intersect is fixedly connected between any two adjacent main chords 1
Bar 3, the termination of any one main chord 1 straight down is fixedly connected with embedded division 4, and termination straight up is then rotatablely connected
There is the fixed part 5 coordinated with embedded division 4, coordinated by embedded division 4 and fixed part 5 to consolidating between upper and lower two standard knots
It is fixed.
As shown in Fig. 2, embedded division 4 includes the embedding bar 6 for being less than main chord 1 with 1 coaxial inner conductor of main chord and diameter, fixed part
5 include loop bar 7, and loop bar 7 is provided with the cylindrical mantle cavity 8 that can be embedded in along direction of axis line by embedding bar 6 from top end surface, will be upper
In the mantle cavity 8 of the insertion of the embedding bar 6 lower section standard knot loop bar 7 of square standard knot, make the main chord 1 of upper and lower two sections standard knot can not be
Relative motion is carried out on horizontal plane.
As shown in Fig. 2, two opposite the first keyways 9 of position are provided with 8 inner wall of mantle cavity, it is solid in two the first keyways 9
Surely ejector spring 10 is connected with, the end of ejector spring 10 towards 9 opening direction of the first keyway is fixedly connected with the first retainingf key
11,9 depth of the first keyway is more than length of first retainingf key 11 along groove depth direction, and is provided with embedding bar 6 and consolidates with two first
Determine the first card slot 12 of the cooperation of key 11.
As shown in Figure 2 and Figure 3, two second keyways 13 identical with the first keyway 9, the second key are also provided with 8 inner wall of mantle cavity
Second retainingf key 14 identical with the first retainingf key 11 is equipped with groove 13, and is also provided with embedding bar 6 and two the second retainingf keys
14 the second card slots 15 coordinated, are jointly fixed embedding bar 6 with the second retainingf key 14 using the first retainingf key 11, strengthen loop bar
Fixed effect between 7 and embedding bar 6.And the Opening length of the first card slot 12 and the second card slot 15 is respectively less than 6 periphery of embedding bar week
The Axis Cross of long a quarter, two the second keyways 13 and two the first keyways 9 is set, and the second keyway 13 is compared to two
Loop bar 7 is turned to correspondence position by a first keyway 9 closer to 8 aperture position of mantle cavity before embedding bar 6 is embedded in mantle cavity 8, is kept away
Exempt from the second retainingf key 14 and be caught in the first card slot 12 to make embedding bar 6 not continue deeper into.
As shown in figure 3, be fixedly connected with resetting spring 16 in 8 bottom of mantle cavity, resetting spring 16 is towards 8 opening direction of mantle cavity
End be fixedly connected with the resetting block 17 being bonded with 8 inner wall of mantle cavity, the distance of 8 bottom of mantle cavity to the first keyway 9, which is more than, to be resetted
Height of the block 17 along 8 depth direction of mantle cavity, when embedding bar 6 is not embedded into mantle cavity 8, the first retainingf key 11 divides with the second retainingf key 14
The block 17 that is not reset is obstructed in the first keyway 9 and the second keyway 13.When in embedding bar 6 insertion mantle cavity 8, the embedding top of bar 6 will be multiple
Position block 17 makes the first retainingf key 11 and the second retainingf key 14 from 17 surface of resetting block is connected to abutting toward 8 bottom squeeze of mantle cavity
On embedding 6 surface of bar, embedding bar 6 continues to stretch into, and finally makes the first retainingf key 11 and the second retainingf key 14 in the elastic force of resetting spring 16
The first card slot 12 is sticked under effect respectively with embedding bar 6 is fixed in the second card slot 15, embedding bar 6 can not be taken off out of mantle cavity 8
Go out.
As shown in figure 3, the slot bottom of the first card slot 12 and the second card slot 15 is square clockwise by axis edge of the axial line of embedding bar 6
To embedding 6 surface of bar is gradually bonded, it is rotatablely connected between loop bar 7 and main chord 1 and rotational plane is perpendicular to axial line.When need by
During upper and lower two standard knots separation, rotating loop bar 7 makes to be relatively rotated between 8 inner wall of embedding bar 6 and mantle cavity, makes the first fixation
Key 11 is moved to along the first card slot 12 with 15 bottom of the second card slot respectively with the second retainingf key 14 abuts embedding 6 surface of bar so as to lose
Coordinate, reach the effect that embedding bar 6 can be deviate from out of mantle cavity 8.
As shown in Figure 3, Figure 4, four main chords 1 have been fixedly connected with latch closure 18, four phases on the outside of the termination of loop bar 7
The loop bar 7 answered is fixedly connected with the outside of the termination of main chord 1 has contact with 19 with what latch closure 18 coordinated, and latch closure 18 is with having contact with 19
It can be fastened when the first retainingf key 11 sticks into 12 slot bottom bosom of the first card slot, latch closure 18 can also play positioning with having contact with 19
Effect.When in embedding bar 6 insertion mantle cavity 8, and the first retainingf key 11 and the second retainingf key 14 stick into the first card slot 12 and second respectively
After 15 slot bottom bosom of card slot, fasten latch closure 18 and have contact with 19 and can prevent from relatively rotating between loop bar 7 and embedding bar 6 and lead
Cause to lose cooperation in the first retainingf key 11 and the first card slot 12.Two swing handles 20, Neng Gouda are also fixedly connected with loop bar 7
To the convenient effect for rotating loop bar 7 and being dismantled.
The specific workflow of the present embodiment is as follows：
When needing to be attached two section standard knots, first pass through the rotation loop bar 7 of swing handle 20 makes ring to correspondence position
Detain 18 and have contact with 19 fastenings, then the main chord 1 that upper and lower two section standard knots are corresponded is directed at same axial line, then makes
Square standard knot declines, and the embedding bar 6 of 1 bottom of top main chord is embedded in the loop bar 7 at 1 top of lower section main chord, embedding bar 6 is downward not
Disconnected pressed home block 17 and substituting resetting block 17 makes the first retainingf key 11 and 14 priority of the second retainingf key withstand on embedding 6 surface of bar, with
Embedding bar 6 to continue to decline, final first retainingf key, 11 and second retainingf key 14 is pushed up out of the first keyway 9 and the second keyway 13 respectively
Go out, and stick into respectively in the first card slot 12 and the second card slot 15, embedding bar 6 is fixed, the company between the section standard knot of enhancing two
Connect stability.
When needing to dismantle two section standard knots being connected, first latch closure 18 is separated with having contact with 19, enables loop bar 7
Rotated relative to main chord 1, then loop bar 7 rotated by swing handle 20, make to be relatively rotated between 8 inner wall of embedding bar 6 and mantle cavity,
First retainingf key 11 moves to 15 bottom of the second card slot along the first card slot 12 and abuts embedding 6 surface of bar respectively with the second retainingf key 14
So as to lose cooperation, enable the abjection out of mantle cavity 8 of embedding bar 6, finally the standard knot of lifting top makes upper and lower two sections standard knot point
From, and resetting block 17 synchronously rises, by the first retainingf key under the elastic force effect of resetting spring 16 with the lifting of embedding bar 6
11 and second retainingf key 14 continue barrier in the first keyway 9 and the second keyway 13.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability
Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but
As long as all protected in the right of the utility model be subject to Patent Law.
