It should be noted that, the material of above-mentioned pipe link 100, end plate 200 and square tube 300 and size, the quantity of described multiple screw and position are only for clearer description the present embodiment, and the utility model is not limited to this.In some other embodiment, corresponding change may be made, such as when described electric block framework is used for the hoisting crane of greater or lesser tonnage, described connecting rod, end plate and the size of square tube can strain large mutually or diminish, then the quantity of multiple screws in such as described pipe link, end plate and square tube also can be three, five or more.
It is the perspective view of the electric block framework 10 of the utility model one embodiment with reference to figure 4, Fig. 4.
Described electric block framework 10 comprises described pipe link 100, described end plate 200 and described square tube 300, and by two end plates 200 being arranged on the both sides of pipe link 100, and the outside two square tubes 300 being arranged on two end plates 200 is formed.
With reference to figure 5, Fig. 5 for the electric block framework 10 shown in Fig. 4 is in the cross-sectional view of pipe link 100, end plate 200 and square tube 300 junction.
Described pipe link 100, end plate 200 are connected with the second bolt 412 by the first bolt 411 with square tube 300.Described first bolt 411 and the second bolt 412 are positioned at screw corresponding in described pipe link 100, end plate 200 and square tube 300, and wherein, the bolt cap of the first bolt 411 is positioned at screw, and the stud of the second bolt 412 is positioned at screw.
Described first bolt 411 and the second bolt 412 are the shaft-like headed part of attached threaded cylinder, and the screwed column part in one end is called stud, and for coordinating with nut or screw, the other end is bolt cap, and the diameter of bolt cap is greater than the diameter of stud.The material of described first bolt 411 and the second bolt 412 is steel.
In the present embodiment, described first bolt 411 and the second bolt 412 measure-alike, the size of the screw in the end plate of described first bolt 411 correspondence and square tube is greater than the size of the screw in the end plate of the second bolt 412 correspondence and square tube, and the bolt cap of described first bolt 411 can be entered in the screw of end plate and square tube.In the present embodiment, the thickness of the bolt cap of described first bolt 411 be not less than the thickness of described end plate and described square tube sidewall and, make the bolt cap of described first bolt 411 can fill screw on completely described end plate and square tube sidewall.
Follow-uply install reel and drop-gear box last time at described end plate 200, sling in the process of weight at spool motion, end plate 200 can be subject to larger shearing force.In the present embodiment, the bolt cap of the first bolt 411 is positioned at screw, and the diameter due to bolt cap is greater than the diameter of stud, and bolt cap can bear the shearing force larger than stud.For needing the electric block framework bearing onesize shearing force, adopting the connection mode be placed in by bolt cap in screw of the present embodiment, just can adopt the bolt of smaller szie to realize.That is, for the bolt of specific dimensions, this connection mode can bear larger shearing force, without the need to selecting larger bolt, reducing the complexity of electric block framed structure, reducing manufacturing cost.
The quantity of described first bolt 411 is at least two, and two the first bolts 411 are positioned at two screws of lie farthest away.In the present embodiment, the quantity of described first bolt 411 is two.Multiple screws in described pipe link 100, end plate 200 and square tube 300 are arranged in a linear, the first screw be arranged in a linear described in described two the first bolts 411 are positioned at and the 4th screw (simultaneously with reference to figure 1-3).Due to being directly proportional of spacing of bolt anti-shear ability and two bolts, in the present embodiment, two the first bolts 411 are arranged in first and last screw, increase the distance between two the first bolts, improve the anti-shear ability of whole electric block framework.
In the present embodiment, the quantity of the second bolt 412 is also two, between two the first bolts 411.The stud of described two the second bolts 412 is positioned at corresponding screw, for clamping described pipe link 100, end plate 200 and square tube 300, increases the friction force between them, for providing longitudinal bearing force.
In the present embodiment, because described first bolt 411 is mainly used in bearing shearing force, described first bolt 411 and the tolerance of corresponding screw are less than the tolerance of described second bolt 412 and corresponding screw.Particularly, described first bolt 411 can be 20 ~ 40 with the tolerance of corresponding screw.In addition, described in the present embodiment, the first bolt 411 is shearing bolt, second bolt 412 is high strength bolt, when electric block framework first is by heavy duty, disposable slight slippage can be produced between framework joint face, thus make the bolt of the first bolt 411 be adjacent to the screw of end plate 200 and square tube 300 first watch, compensate machining tolerance, can effectively reduce framed structure again stand under load time dynamic load impact.
It should be noted that, in other embodiments, the quantity of described first bolt also can more than two, such as, can be 3 or 4 etc., and in multiple first bolt at least two are positioned at first screw and last screw that are arranged in a linear, to provide larger anti-shear ability.In other embodiments, the quantity of described second bolt also can be 1,3 or other quantity.In other embodiments, the size of described first bolt and the second bolt also can be different.
Accordingly, the utility model embodiment still provides a kind of electric block, and described electric block comprises above-mentioned electric block framework, and is arranged on the reel between described end plate, and the drop-gear box be connected with described reel.
Accordingly, the utility model embodiment still provides a kind of hoisting crane, and described hoisting crane comprises above-mentioned electric block; Support main beam, described electric block is arranged on described support main beam, and can move along described support main beam; And aerial conveyor, described support main beam can carry described electric block and move along described aerial conveyor.
Although the utility model discloses as above, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
