Specific implementation mode
To make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments,
The present invention will be further described in detail.However, it should be understood that specific embodiment described herein is only used to solve
The utility model is released, the range being not intended to limit the utility model.
As shown in Figure 1 and Figure 2, a kind of fixed auxiliary dismounts limiting device, including principal arm 1, auxiliary 2, is set on the principal arm 1
There are minor details arm arm head 3, the minor details arm arm head 3 to be equipped with the left hinge hole of principal arm, the left hinge hole of principal arm includes principal arm upper left
Hinge hole, principal arm lower-left hinge hole, the auxiliary 2 are equipped with the left hinge hole of auxiliary corresponding with the left hinge hole of principal arm, the pair
The left hinge hole of arm includes auxiliary upper left hinge hole, auxiliary lower-left hinge hole；
It further include the driving mechanism 7 being mounted on minor details arm arm head 3；
The driving mechanism 7 is mounted on principal arm lower-left hinge hole side, when principal arm upper left hinge hole and auxiliary upper left hinge
After the completion of the centering of hole, the axis pin 6 of fastening is installed in the upper hinge hole 4 that the two is formed, the driving mechanism 7 drives auxiliary left
Lower hinge hole is moved, and makes auxiliary lower-left hinge hole and the hinge hole centering of principal arm lower-left, the two cooperatively forms lower hinge hole 5, described
The axis pin 6 of fastening is installed in lower hinge hole 5.
As the improvement of embodiment, after auxiliary 2 is rocked to operating position, upper hinge hole, plugs hinge on the left of first centering
Spot hole axis pin, then this at present hinge hole can not centering, and deviation is maximum.(such as the hand of driving mechanism 7 is set at lower hinge hole
Dynamic, electrohydraulic cylinder or jack, using Manual hydraulic jack as example explanation in the present embodiment), which can push away
Dynamic auxiliary, compensates the deviation of amount of deflection product so that the centering of lower hinge hole, and then facilitate hinge hole axis pin under plug,
As a further improvement, the driving mechanism 7 uses Manual hydraulic jack, the Manual hydraulic jack packet
Include manual pump 8, the oil cylinder being connect with manual pump 89, detachable rocking bar 10, Self-resetting knob 11；The detachable rocking bar 10 and from
It resets knob 11 to be arranged in manual pump 8, oil cylinder 9 is connected with the minor details arm arm head 3.
Further, the oil cylinder 9 is bolted with minor details arm arm head 3.
The utility model provides a kind of equipped with the crane for fixing auxiliary dismounting limiting device described in any of the above-described.
The operation principle of the utility model is as follows：
When auxiliary is expanded to working condition by stationary state, driving mechanism 7 is in reset position, on principal arm and auxiliary
Hinge hole is centering target on left side, does not consider lower hinge hole centering situation, and upper 4 centering of hinge hole is good at this time, and axis pin 6 can be light
Pine is inserted into, as shown in Fig. 2, and this hinge alignment deviation is maximum at present, as shown in Figure 3.
At this point, driving mechanism 7 functions to, setting manual pump 8 in driving mechanism 7, oil cylinder 9, detachable rocking bar 10, from
Reset knob 11, wherein detachable rocking bar 10 and Self-resetting knob 11 are separately positioned in manual pump 8, oil cylinder 9 by bolt and
Minor details arm arm head 3 is connected.It is artificial to swing rocking bar, so that manual pump 8 is bought oil to 9 big intracavitary of oil cylinder, the cylinder rod of oil cylinder 9 is pushed to stretch out,
The cylinder rod of oil cylinder 9 pushes lower hinge hole movement on the left of auxiliary, gradually reduces alignment deviation value at lower hinge hole 5, until an auxiliary left side
Centering is realized in lower hinge hole with principal arm lower-left hinge hole, as shown in Figure 4.
After centering, it is inserted into axis pin at lower hinge, realizes the fixation of auxiliary working condition.Oil cylinder in hoisting process in order to prevent
9 stress, rotation Self-resetting knob 11, make oil cylinder 9 realize Self-resetting.
When needing auxiliary being retracted to stationary state by working condition, the cylinder rod of oil cylinder 9 is withstood into auxiliary lower-left first
Hinge makes axis pin 6 not stress or reduce 6 stress of axis pin, extracts axis pin 6.Then rotation Self-resetting button 11 keeps oil cylinder 9 real
Existing Self-resetting, while auxiliary can automatically return to state shown in Fig. 3 due to the presence of amount of deflection, realize the compensation of auxiliary amount of deflection, this
At present free at hinge hole, it 6 stress very little of axis pin at upper hinge hole or does not stress, axis pin 6 at the upper hinge of extraction can be facilitated,
And then it is retracted to auxiliary stationary state around hinge on the right side of auxiliary.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Any modification, equivalent replacement or improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
