Description
Technical field
The utility model relates to the split type connecting device field of stacker crane body, especially a kind of half pin shaft connection structure.
Background technology
For the tower-body standard section bearing pin of tower crane, traditional structure forms is exactly an overall bearing pin.Every two standard knots are by multiple pinned connection, and the requirements such as phase mutual right alignment, parallelism, squareness, and in fitting process, to fit into pin-and-hole more difficult sometimes for each bearing pin, and for Large Towers machine, pin diameter is large, and thus weight is large, not easily Assembly &Disassembly.
Utility model content
It is better and be convenient to half pin shaft connection structure of Assembly &Disassembly that technical problem to be solved in the utility model is to provide a kind of fastening effect that connects.
The utility model solves the technical scheme that its technical matters adopts: half pin shaft connection structure, comprise the stub being provided with stub inclined-plane, the pair pin being provided with secondary pin inclined-plane and be connected in stub and the secondary catch selling end head, wherein said stub and secondary pin are fitted tightly by stub inclined-plane and secondary inclined-plane of sell and are formed complete bearing pin entirety, one end of stub is provided with stub fixed orifice, bolt of rear end plate through catch and to be fixed in stub fixed orifice thus by stub and secondary sell be connected fastening.
Further, comprise pad, described pad is arranged between catch and bolt of rear end plate.
Further, comprise at least one spring washer, described spring washer is arranged between pad and bolt of rear end plate.
The beneficial effects of the utility model are: when reality uses, first stub and secondary pin are placed in hole to be tightened, then, catch be connected in stub and secondary pin end head thus allow periderm catch outside the termination of bearing pin entirety block, then, only bolt of rear end plate need be passed catch and tightens is fixed in stub fixed orifice, in quiet process, constantly be close between stub inclined-plane and secondary pin inclined-plane, stub and secondary pin are owing to being blocked by catch, also can more and more be close between stub and secondary pin, final realization fixing structure.The utility model devises stub inclined-plane and secondary pin inclined-plane cleverly, two and half bearing pins with identical inclined-plane are assembled into an overall bearing pin by other parts, actv. solves bearing pin assembling and dismounting difficult problem, and the problem of a dead lift difficulty to be caused greatly by single bearing pin weight, convenience very during use, is particularly useful in the technique for fixing of large-scale bearing pin.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Be labeled as in figure: stub 1, stub fixed orifice 11, stub inclined-plane 12, secondary pin 2, secondary pin inclined-plane 22, catch 3, pad 4, spring washer 5, packing ring 6, bolt of rear end plate 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Half pin shaft connection structure as shown in Figure 1, comprise be provided with stub inclined-plane 12 stub 1, be provided with the secondary pin 2 on secondary pin inclined-plane 22 and be connected in the catch 3 of stub 1 and secondary pin 2 end head, wherein said stub 1 and secondary pin 2 are fitted tightly by stub inclined-plane 12 and secondary inclined-plane 22 of sell and are formed complete bearing pin entirety, one end of stub 1 is provided with stub fixed orifice 11, and bolt of rear end plate 7 is through catch 3 and to be fixed in stub fixed orifice 11 thus to be connected fastening by stub 1 with secondary pin 2.
For Large Towers machine, traditional pin diameter is large, and thus weight is large, not easily Assembly &Disassembly, the inconvenience operated very.The utility model looks for another way, and creationary " bearing pin " is changed into the stub 1 and secondary pin 2 that are divided into two.But, meanwhile, need again the problem that the compact siro spinning technology between solution stub 1 and secondary pin 2 is fixing.The utility model is by design, have selected the stub 1 on stub inclined-plane 12 and be provided with the secondary pin 2 on secondary pin inclined-plane 22, described stub 1 and secondary pin 2 are fitted tightly by stub inclined-plane 12 and secondary inclined-plane 22 of sell and are formed complete bearing pin entirety, also be connected with catch 3 at stub 1 and secondary pin 2 end head in addition, last, bolt of rear end plate 7 to be fixed in stub fixed orifice 11 through catch 3 thus to be connected fastening by stub 1 with secondary pin 2.As shown in Figure 1, just because of stub inclined-plane 12 and secondary pin inclined-plane 22 and the working in coordination of catch 3 being connected in stub 1 and secondary pin 2 end head, occur that bolt of rear end plate 7 is more tightened, and stub 1 more moves towards catch 3, stub inclined-plane 12 pastes tighter and tighter together with catch 3 with secondary pin inclined-plane 22, fixes completely by stub 1 and secondary pin 2.
General, can select use packing ring 6 at bolt of rear end plate 7 place thus make fastening effect better.Certain, in view of the needs of reality, following scheme can also be taked: can select to set up pad 4 between catch 3 and bolt of rear end plate 7, and between pad 4 and bolt of rear end plate 7, set up at least one spring washer 5, thus make fastening effect better.
