Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Referring to Fig. 1 to Fig. 5, the structure of connector provided in an embodiment of the present invention, the connector in the present embodiment are shown
It is illustrated for being applied to tower crane, as shown, the connector includes: movable snap-gauge 1, fixing seat 2, operating shaft 3 and determines
Position pin 4.
Specifically, the first opening mounting groove 11 and the first pin hole 12, operating shaft 3 and active card are provided on movable snap-gauge 1
Plate 1 connects.Fixing seat 2 can connect with the tower cap 93 of tower crane or be an integral structure with tower crane tower cap 93, set in fixing seat 2
It is equipped with the second opening mounting groove 201, first opening card slot 202, second opening card slot 203 and the second pin hole 204, operating shaft 3 can
Switch in the first opening card slot 202 and in the second opening card slot 203, with the opposite position of change activity snap-gauge 1 and fixing seat 2
It sets.Referring to fig. 2, by the way that the suitable position in fixing seat 2 is arranged in the first opening opening card slot 203 of card slot 202, second, make
When operating shaft 3 is connected in the second opening card slot 203, the first pin hole 12 and the second pin hole 204 can relatively in, positioning pin 4 is inserted into
After in the first pin hole 12 and the second pin hole 204 in relatively, the first opening mounting groove 11 and the second opening mounting groove 201 are firmly
It is encircled into the pin hole 200 for connecting pin 91 to be fixedly mounted, which can be to be mounted on counter-jib 92 or crane arm
Pin shaft on otic placode, thus by counter-jib 92 or crane arm together with 93 Fast Installation of tower cap of tower body.Referring to Fig. 3, pass through
Positioning pin 4, moving operation axis 3 are extracted, and is not necessarily to manually buttress activity after operating shaft 3 is connected in the first opening card slot 202
Snap-gauge 1, the first opening mounting groove 11 are maintained at the state mutually separated with the second opening mounting groove 202, take out with can be convenient
Connecting pin 91, to simplify high altitude operation difficulty, is realized flat so that counter-jib or crane arm are disassembled from tower cap 93
Weighing apparatus arm or crane arm and tower cap 93 are rapidly assembled and disassembled.
In addition, the length and diameter of positioning pin 4 can be much smaller than connecting pin 91, hold so that the plug of positioning pin 4 operates
Easily implement, beats positioning pin 4 for a long time in the air without being used in height, the installation of connecting pin 91 itself is without beaing operation, further
Improve the safety of high altitude operation.Preferably, one end of the positioning pin 4 is formed with the limit shaft shoulder, and the other end is provided with lock pin
Hole can install D type pin or U-shaped pin in lockpin hole, be moved with matching with the limit shaft shoulder for limiting the axial of positioning pin 4
It is dynamic.
Preferably, the first opening card slot 202 and the second opening card slot 203 are the U-type groove of opening upwards, the first open card
Slot 202 and the second opening card slot 203 can use length appropriate, and operating shaft 3 can be stably maintained under the effect of gravity
In each opening card slot, so that the first opening mounting groove 11 and the second opening mounting groove 201 are maintained at disengaged position or combine shape
State.Preferably, the slot bottom of the first opening mounting groove 11 and the second opening mounting groove 201 is arc-shaped, so that the pin being encircled into
Hole 200 is adapted with the shape of connecting pin 91.
A kind of preferred embodiment of fixing seat 2 is also shown in the present embodiment, as shown in figure 4, the fixing seat 2 includes double
The otic placode 21 of layer and the bottom plate 22 of single layer, otic placode 21 are welded on the two sides of bottom plate 22, the first opening card slot 202, the second open card
Slot 203 and the second pin hole 204 are provided on otic placode 21, and the second opening mounting groove 201 is provided on bottom plate 22.Movable snap-gauge 1
Among two otic placodes 21, the distance between double-deck otic placode 21 can be slightly larger than the thickness of movable snap-gauge 1, in this way, neither shadow
3 drive activity snap-gauge of operating shaft, 1 free switching position is rung, otic placode 21 can arrive again and play guiding role to the movement of movable snap-gauge 1,
Also ensure structural strength when fixing seat 2 and movable snap-gauge 1 surround pin hole 200.In addition, by can also be seen that in Fig. 4 in ear
It is further connected with stiffening plate 23 between plate 21, is used for enhancing structure intensity.It is appreciated that fixing seat 2 can also have other
Numerous embodiments, do not enumerate herein.
Referring to Fig. 5, it is preferable that operating shaft 3 welds together with movable snap-gauge 1 in the present embodiment, and operating shaft 3 and work
Dynamic snap-gauge 1 is perpendicular, and structure can also simply reduce manufacturing cost.
It should be noted that, although the connector is illustrated for being applied to tower crane in the present embodiment, it is clear that the company
The application range of connector is not limited to tower crane.
The embodiment of the invention also provides a kind of engineering machinery, which is provided with above-mentioned connector.This implementation
The engineering machinery is specifically tower crane in example, and the fixing seat 2 of connector is connect with the tower cap 93 of tower crane, and connecting pin 91 is installed on tower
On the counter-jib 92 or crane arm of machine.
Referring to figs. 2 and 3, such as using the assembling process of the counter-jib 92 for the tower crane for having the connector and tower crane tower cap 93
Under: it is located at operating shaft 3 in first opening card slot 202, the first opening mounting groove 11 is detached from the second opening mounting groove 201,
Then in the second opening mounting groove 201 connecting pin 91 of counter-jib 92 being put into fixing seat 2, then make operating shaft from first
It is moved in the second opening card slot 203 in opening card slot 202, movable snap-gauge 1 accordingly moves down, and can rotate operating shaft 3, finally makes
First opening mounting groove 11 is encircled into pin hole 200 with second mounting groove 201 that is open, and connecting pin 91 is located in pin hole 200, and at this time the
One pin hole 12 and the second pin hole 204 relatively in, then by the first pin hole 12 and the second pin hole 204 in the insertion relatively of positioning pin 4
In, counter-jib 92 i.e. with tower cap 93 quickly, be firmly coupled to each other.
The disassembly process of the counter-jib of above-mentioned tower crane is as follows: extraction positioning pin 4 first, rotation process axis 3 and by operating shaft 3
By being moved in the first opening card slot 202 in the second opening card slot 203, the first opening mounting groove 11 is detached from the second opening mounting groove
201, movable snap-gauge 1 will not glide, and the connecting pin 91 of counter-jib 92 is taken out from the second opening mounting groove 201.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
