First fixed block 110 (or second fixed block 120) is clamped, and connecting pin 210 stops operating, first segment arm and the second section arm
Between angular adjustment complete.
It should be noted that：" swing " in " fixation " and " swinging ontology 200 " in " fixed ontology 100 " is opposite
Concept, that is, first segment arm and the second section arm, when being adjusted, it is pendulum to swing ontology 200 relative to fixed ontology 100
Dynamic, the object of reference that fixed ontology 100 is swung as swing ontology 200, therefore it is named as fixed ontology 100, but this pass
System is not absolute, that is, fixed ontology 100 and swing the fixation in ontology 200 and swing only one it is opposite general
It reads, or in order to distinguish fixed ontology 100 and swing the difference between ontology 200, is not limited to 100 He of fixed ontology
The actual motion of ontology 200 is swung, actual motion is then the connection relation described in application documents.
" the first swinging block 230 can be clamped with the first fixed block 110 or the second swinging block 240 can be fixed with second
"or" in the clamping of block 120 " refers to that only a kind of situation occurs, that is, the first swinging block 230 and the first fixed block 110 block
When connecing, the second swinging block 240 cannot be clamped with the second fixed block 120；Similarly, the first swinging block 230 and the first fixed block
110 are detached from or when not being clamped, the second swinging block 240 is likely to be clamped with the second fixed block 120, the second swinging block 240 and the
When two fixed blocks 120 are clamped, the first swinging block 230 and the first fixed block 110 can not be clamped.Using 110 He of the first fixed block
Second fixed block 120 plays the role of limiting swinging angle.
As shown in Figure 1, connecting pin 210 is provided with limiting slot 300, the first swinging block 230 and the second swinging block 240 are set to
The both sides of limiting slot 300；The outside of fixed ontology 100 is provided through the limited block 340 of limiting slot 300, the first fixed block 110
The both sides of limited block 340 are set to the second fixed block 120；First swinging block 230 and the opposite side of the second swinging block 240
It is respectively arranged with blocked hole 250, the first fixed block 110 and the second fixed block 120 are able to be caught in blocked hole 250.
Swing ontology 200 and swing (or backswing) relative to fixed ontology 100 is positive, one end of limiting slot 300 with
When limited block 340 contradicts, the first fixed block 110 is caught in the blocked hole 250 for being set to the first swinging block 230, the adjusting of the direction
It completes；Ontology 200 is swung relative to fixed 100 backswing of ontology (forward direction is swung), the other end and limited block of limiting slot 300
When 340 conflict, the second fixed block 120 is caught in the blocked hole 250 for being set to the second swinging block 240, and the adjusting of the direction is completed.
Simple in structure, entire adjustment process is succinctly quick, can significantly improve the flexibility of lifting arm, to improve construction
And the efficiency of emergency repair.
As shown in Fig. 2, the top side of limiting slot 300 is arranged at intervals with multiple first elastomer blocks 310, the bottom side of limiting slot 300
It is arranged at intervals with multiple second elastomer blocks 320, along circumferential direction wherein the one of the first elastomer block 310 and the second elastomer block 320
Side, which is respectively arranged with, moves back pressure inclined surface 330, and the pressure inclined surface 330 of moving back of the first elastomer block 310 and the second elastomer block 320 is mutually put down
Row；Limited block 340 is respectively arranged with cutting limited block 340 corner angle in diagonal position and compresses inclined surface 350, is located at limiting slot
Setting is intersected in the inclined surface 350 that compresses of 300 top side with the pressure inclined surface 330 of moving back of the first elastomer block 310, is located at limiting slot 300
The pressure inclined surface 330 of moving back for compressing inclined surface 350 and the second elastomer block 320 of bottom side intersect setting；Limited block 340 is along limit
Position slot 300 compresses the first elastomer block 310 and the second elastomer block 320, and the first elastomer block 310 and the second elastomer block 320 can retract
To fixed ontology 100.
" the pressure inclined surface 330 of moving back of the first elastomer block 310 and the second elastomer block 320 is mutually parallel ", by prolonging for limiting slot 300
Direction, that is, circumferential direction are stretched, both direction, forward and reverse are divided into, the first elastomer block 310 moves back pressure 330 He of inclined surface
Second elastomer block 320 moves back pressure inclined surface 330 in circumferential direction backwards to being arranged, that is, first elastomer block 310 moves back pressure
Inclined surface 330 is set to the side of the first elastomer block 310, and the pressure inclined surface 330 of moving back of the second elastomer block 320 is set to the second bullet
The other side of property block 320.
" limited block 340 is respectively arranged with cutting limited block 340 corner angle in diagonal position and compresses inclined surface 350 " also
It is that indent is set to limited block 340 when compressing inclined surface 350, rather than is provided projectingly on limited block 340, this kind of mode determines
It is side and to extend from outside to inside to limiting slot 300 side wall to compress inclined surface 350.
" press 330 phase of inclined surface with moving back for the first elastomer block 310 in the inclined surface 350 that compresses positioned at the top side of limiting slot 300
Setting is handed over, the moving back for inclined surface 350 and the second elastomer block 320 that compress positioned at the bottom side of limiting slot 300 presses inclined surface 330 to intersect to set
It sets ".For limited block 340 during being moved along a direction of limiting slot 300, one end of limited block 340 compresses inclination
Face 350 can resist the first elastomer block 310 positioned at 300 side of limiting slot the side for moving back pressure inclined surface 330 is not arranged and incites somebody to action
First elastomer block 310, which compresses, to be retracted into connecting pin 210, and the side for compressing inclined surface 350 is not arranged for the other end of limited block 340
Wall then acts on moving back for the second elastomer block 320 positioned at 300 side of limiting slot and inclined surface 330, the second elastomer block 320 is pressed to limit
It is retracted into connecting pin 210 under the action of the side wall of position block 340.When limited block 340 is along another direction of limiting slot 300
Mobile, then the action at 340 both ends of limited block exchanges, that is, the side wall of one end of limited block 340 is acted on pressure inclined surface 330 is moved back
When, the inclined surface 350 that compresses of the other end is just acted on the side wall that the offside for moving back pressure inclined surface 330 is not arranged.
It is compressed between 300 side wall of inclined surface 350 and limiting slot as shown in Fig. 2, moving back pressure inclined surface 330 and can enter.
In such cases, the first elastomer block 310 or the second elastomer block 320 peak (" peak " refer to it is right
Answer the maximum point of the side wall spacing of the limiting slot 300 of side) less than inclined surface 350 is compressed, in this way, compressing inclined surface 350 can
Act on the first elastomer block 310 or the second elastomer block 320 the side wall for moving back pressure inclined surface 330 is not arranged, by the first elasticity
Block 310 and the second elastomer block 320 are compressed and are retracted into connecting pin 210.
As shown in Figure 1, buffer spring 360 is provided in blocked hole 250, the first fixed block 110 and the second fixed block 120
End it is respectively hemispherical.
Connecting pin 210 is swung around fixed ontology 100, and buffer spring 360 is arranged, and can reduce the first fixed block 110 card
Enter the impact force of the first swinging block 230 or the second fixed block 120 is caught in the impact force of the second swinging block 240.Extend swing arm dress
The usage time set.
