Abstract
The utility model discloses a kind of hoisting crane box type telescopic arm slide block mechanism, comprise and be arranged on external extension arm two bottom sides for supporting some sliding blocks of interior telescopic boom, also comprise some slide block bearing pins and some slide block bearings, what slide block bearing can be rotated around its axle center by slide block bearing pin is arranged on external extension arm bottom outside, the axle center of slide block bearing pin parallels with the telescopic direction of telescopic boom, bottom telescopic boom, each side has some through holes corresponding with slide block bearing outside, sliding block is arranged in slide block bearing, the upper surface of this sliding block contacts with interior telescopic boom two bottom sides through corresponding through hole, the axle center of telescopic boom and the axle center automatic centering of external extension arm in controlling.Sliding block of the present utility model can rotate around the axle center of slide block bearing pin with slide block bearing, and can operational space be the space of an opening, installation and removal be convenient; The gap with arm can be regulated by automatic swing, make arm in alignment all the time, the axle center automatic centering of inside and outside joint telescopic boom is overlapped.
Description
Technical field
The utility model belongs to hoisting crane technical field, particularly relates to a kind of hoisting crane box type telescopic arm slide block mechanism.
Background technology
By slider support between existing hoisting crane box type telescopic arm, as shown in Figure 3, hoisting crane box type telescopic arm slide block mechanism comprises arm top shoe and arm sliding block a, wherein arm sliding block a is fixed on often saving on the acromere telescopic boom b of arm arm front end except epimerite arm by the mode of welding, and arm sliding block a upper surface contacts with the bottom outside of lateral expansion arm c and supports.
The following defect of above-mentioned this hoisting crane box type telescopic arm slide block mechanism ubiquity: 1, install sliding block again after need installing arm, can operational space too little, installation and removal difficulty; 2, because sliding block adopts fixed installation, when arm bending edges does not reach technological requirement, the inoperative limit of arm can be caused directly to contact work with sliding block, and form a fixing form, cannot regulate; 3, direct bottom sliding block and acromere telescopic boom fit inside, next joint lateral expansion arm coordinates with sliding block upper surface, when arm make there is mild distortion, cross section, below angle situation not etc. time, the axle center of the inside and outside joint telescopic boom cooperatively interacted can be caused not overlap, the power of hanging of arm not only can be made to be decomposed, in telescopic process, also easily to occur the phenomenon occurring after inside and outside joint telescopic boom stretches to rub.
Utility model content
The purpose of this utility model is to provide that a kind of efficiency is high, labour intensity is low, waste less, dress alms bowl weight and compacting uniform hoisting crane box type telescopic arm slide block mechanism.
This hoisting crane box type telescopic arm slide block mechanism that the utility model provides, comprise and be arranged on external extension arm two bottom sides for supporting some sliding blocks of interior telescopic boom, also comprise some slide block bearing pins and some slide block bearings, what described slide block bearing can be rotated around its axle center by slide block bearing pin is arranged on external extension arm bottom outside, the described axle center of slide block bearing pin parallels with the telescopic direction of telescopic boom, bottom described external extension arm, each side has some through holes corresponding with slide block bearing, described sliding block is arranged in slide block bearing, the upper surface of this sliding block contacts with interior telescopic boom two bottom sides through corresponding through hole, the axle center of telescopic boom and the axle center automatic centering of external extension arm in controlling.
Between the end and external extension arm of described slide block bearing, cushion rubber is installed.
Compared with prior art, the utility model has the following advantages:
1, sliding block is by slide block bearing, is fixed on arm bottom outside with slide block bearing pin, and can operational space be the space of an opening, installation and removal be convenient.
2, the axle center of slide block bearing pin parallels with the telescopic direction of telescopic boom, and sliding block can rotate around the axle center of slide block bearing pin with slide block bearing, when arm bending edges does not reach technological requirement, can regulate the gap with arm by automatic swing, make arm in alignment all the time; When arm make there is mild distortion, cross section, below angle situation not etc. time, also can automatic swing, the axle center automatic centering of inside and outside joint telescopic boom is overlapped, makes hanging to try hard to keep and holding optimum regime of arm, avoid the generation occurring inside and outside joint telescopic boom friction phenomenon in telescopic process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that Figure 1A-A locates semi-sictional view structure for amplifying schematic diagram.
Fig. 3 is the structural representation of prior art.
Detailed description of the invention
As can be seen from Fig. 1 and Fig. 2, this hoisting crane box type telescopic of the utility model arm slide block mechanism, comprise some slide block bearing pins 1, some slide block bearings 2, some sliding blocks 3, external extension arm 4 and interior telescopic boom 5, wherein slide block bearing 2 is respectively arranged on external extension arm 4 bottom outside by a slide block bearing pin 1, the axle center of slide block bearing pin 1 parallels with the telescopic direction of telescopic boom, slide block bearing 2 can rotate around the axle center of slide block bearing pin 1, bottom telescopic boom 4, each side has some through holes 41 corresponding with slide block bearing 2 outside, each sliding block 3 is arranged in corresponding slide block bearing 2, the upper surface of each sliding block 3 contacts with interior telescopic boom 5 two bottom sides through corresponding through hole 41 and supports this interior telescopic boom 5, the axle center of telescopic boom 5 and the axle center automatic centering of external extension arm 4 in controlling.
As can be seen from Figure 2, between the end and external extension arm 4 of this practical novel slide block bearing 2, cushion rubber 6 is installed.
In use procedure of the present utility model, when there being gap in next joint between telescopic boom 5 and a certain sliding block 3, the meeting of this sliding block 3 rotates around the axle center of slide block bearing pin 1 with slide block bearing 2, by rotating the accuracy of alignment and gap that slowly regulate interior telescopic boom 5 and external extension arm 4.
Claims (2)
1. a hoisting crane box type telescopic arm slide block mechanism, comprise and be arranged on external extension arm two bottom sides for supporting some sliding blocks of interior telescopic boom, it is characterized in that: this mechanism also comprises some slide block bearing pins and some slide block bearings, what described slide block bearing can be rotated around its axle center by slide block bearing pin is arranged on external extension arm bottom outside, the described axle center of slide block bearing pin parallels with the telescopic direction of telescopic boom, bottom described external extension arm, each side has some through holes corresponding with slide block bearing, described sliding block is arranged in slide block bearing, the upper surface of this sliding block contacts with interior telescopic boom two bottom sides through corresponding through hole, the axle center of telescopic boom and the axle center automatic centering of external extension arm in controlling.
