Further, above-mentioned locations is bar-shaped, and conveniently to be fixed on the permanent seat, the backguy of being bound is as the criterion its external diameter size not destroy.
Further, the said fixing seat is provided with for an end of locations the peg graft fixing knock hole and the screw or the pin of fixed positioning piece.
Further, above-mentioned locations has the location shaft part of the knock hole that is arranged in permanent seat and is positioned at the backguy canned paragraph of a side of permanent seat, and the opposite side of permanent seat is provided with and locatees the screw that shaft part is threaded.
Further, above-mentioned locations by screw retention to permanent seat.
According on the other hand of the present utility model, a kind of telescopic crane boom is provided, comprise the brachium sensor that is fixed on the basic arm and according to anchorage shoe described above.This anchor fitting comprises: permanent seat is installed on the minor details arm of telescopic boom; And locations, removably be fixed on the permanent seat, wherein, the backguy and the locations of brachium sensor are fixed together.
Further, above-mentioned backguy has self-align rear that freely extends, and the end of this rear has appliance plug.
Further, the arm that respectively saves of above-mentioned telescopic boom is provided with the backguy guiding mechanism.
Anchorage shoe of the present utility model and telescopic crane boom can make the backguy cable easy accessibility of telescopic boom brachium sensor, prevent the error in length brought in the maintenance process, need calibrating length and the correction carried out after avoiding maintaining.
Except purpose described above, feature and advantage, other purpose, feature and the advantage that the utlity model has will be described in further detail in conjunction with the accompanying drawings.
Description of drawings
Constitute this specification sheets a part, be used for further understanding accompanying drawing of the present utility model and show preferred embodiment of the present utility model, and be used for illustrating principle of the present utility model with specification sheets.Among the figure:

Fig. 2 shows first embodiment according to the anchorage shoe of brachium sensor of the present utility model;
Fig. 3 shows second embodiment according to the anchorage shoe of brachium sensor of the present utility model;
Fig. 4 shows the 3rd embodiment according to the anchorage shoe of brachium sensor of the present utility model; And
Fig. 5 shows the 4th embodiment according to the anchor fitting of brachium sensor of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Fig. 1 shows the scheme drawing of the telescopic crane boom of the anchorage shoe with brachium sensor.As shown in Figure 1, anchorage shoe comprises: permanent seat 15 is installed on the minor details arm of telescopic boom 10; And locations 14, removably be fixed on the permanent seat 15, wherein, the backguy 13 of brachium sensor 11 is fixed on the locations 14.
Backguy 13 preferably has the tail end 13b that freely extends for self-align 14, and rear is provided with appliance plug 13a (as shown in Figure 2), so can peg graft with the socket of arm head control capsule 10a, conveniently is electrically connected.If the arm head electric device is less, also can not need control capsule 10a, directly remove to connect electric device by the backguy cable end.
By locations 14 being set and backguy being fixed on the locations 14, make the gage length of backguy can not change.When maintenance, get final product from permanent seat 15 dismounting locationss 14, need not to dismantle backguy 13, when maintenance finishes, again this locations 14 is installed on the permanent seat 15, gage length is kept and is immobilized in this process, and maintenance is convenient.
Compare backguy 13 convenient disassemblies of the present utility model, and the demarcation of brachium sensor and revise and before entrucking, just to carry out, and then the speed that can quickening equipment rolls off the production line with the prior art on the connecting element of the minor details arm that backguy is wrapped in telescopic boom.
The arm that respectively saves of telescopic boom is provided with backguy guiding mechanism 12, backguy guiding mechanism 12 on the every joint arm of except that the minor details arm other can be dismantled, because it is less that locations 14 is pulled down the back volume from permanent seat 15, can be retracted to basic arm very easily so the backguy cable need not just to pull down from locations 14.When maintenance finishes, again this locations 14 is installed on the permanent seat 15, gage length is kept and is immobilized in this process.When maintenance, also can and make locations 14 bounce back to basic arm with 12 dismountings of backguy guiding mechanism.
Certainly, locations 14 also can be made other shape of the backguy guiding mechanism 12 that respectively saves arm that is fit to pass telescopic boom, for example, and ring-type.
Fig. 2 shows first embodiment according to the anchorage shoe of brachium sensor of the present utility model.As shown in Figure 2, an end of locations 14 is plugged on the permanent seat 15 and by screw or pin 16 and fixes.This locations 14 can become the pole shape, and this screw or pin 16 run through locations 14 and permanent seat 15, realizes the purpose that locations 14 is fixed on permanent seat 15.
Fig. 3 shows second embodiment according to the anchorage shoe of brachium sensor of the present utility model.As shown in Figure 3, locations 14 has the location shaft part 14a of the knock hole that is arranged in permanent seat 15 and is positioned at the backguy canned paragraph 14b of a side of permanent seat 15, and the opposite side of permanent seat 15 is provided with and locatees the screw 17 that shaft part 14a is threaded.
Fig. 4 shows the 3rd embodiment according to the anchorage shoe of brachium sensor of the present utility model.As shown in Figure 4, locations 14 directly is fixed on the permanent seat 15 by a plurality of screws 18.
Fig. 5 shows the 4th embodiment according to the anchorage shoe of brachium sensor of the present utility model.As shown in Figure 5, locations 14 becomes the integral body that cannot dismantle with backguy 13, for example can locations 14 be formed in the backguy 13 by modes such as injection mo(u)ldings.This locations 14 is easy to by permanent seat 15 it be gripped.
Again as shown in Figure 1, according to telescopic crane boom of the present utility model, has the anchorage shoe in brachium sensor and the foregoing description.So, when telescopic crane boom is maintained, the backguy cable easy accessibility of brachium sensor.The arm that respectively saves of the telescopic boom of hoisting crane is provided with backguy guiding mechanism 12 in the foregoing description.
By above description as can be seen, anchorage shoe of the present utility model can make the backguy cable easy accessibility of telescopic boom brachium sensor, prevent the error in length brought in the maintenance process, need calibrating length and the correction carried out after avoiding maintaining.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
