Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-5, a kind of bridge crane, including gantry 1, the bottom of 1 ontology of gantry offer sliding slot 2, sliding slot 2 Electric telescopic rod 3 is fixedly connected in two opposed inner walls, the one end of each electric telescopic rod 3 far from 2 side wall of sliding slot is fixed It is connected with sliding block 4, each sliding block 4 slides in sliding slot 2, and the bottom middle position of gantry 1 is equipped with trolley 5, and lifting is small The top section of vehicle 5 is in the inside of sliding slot 2, and the bottom end of trolley 5 is wrapped with the first wirerope 6, the first wirerope 6 Bottom is fixedly connected with the first fixed block 7, and the top of the first fixed block 7 is fixedly connected with hook 8, the bottom both ends point of gantry 1 Not She You cabinet 9, bottom of the top of each cabinet 9 with sliding block 4 be fixedly linked, and the inside of each cabinet 9 is equipped with elevator Machine 10, the side of each cabinet 9 are equipped with motor 11, and the output end of motor 11 is fixedly linked by shaft coupling with hoist engine 10, The second wirerope 12 is wrapped on hoist engine 10, the side of cabinet 9 offers unwrapping wire hole, and one end of the second wirerope 12 is by putting String holes stretches out cabinet 9, and the two sides of the first fixed block 7 are fixedly connected with the second fixed block 13, one end of each second wirerope 12 It is fixedly linked with each second fixed block 13.

The diameter of second wirerope 12 is greater than the diameter of the first wirerope 6, it is therefore an objective to it is solid can steadily to control first The case where determining block 7, preventing weight from shaking in lifting.

Sheath is equipped on each unwrapping wire hole, it is therefore an objective to avoid the occurrence of the damage by cabinet 9 of the second wirerope 12.

The trolley 5 has been the prior art, and the variety of components on trolley 5 is numerous, is collectively referred to as in the text Trolley 5.

Working principle: when hook 8 tangles weight, start trolley 5, the first wirerope 6 on trolley 5 starts It shrinks, at the same time, starts two motors 11, the rotation of two motors 11 drives the rotation of two hoist engines 10 respectively, and two The rotation of hoist engine 10 drives the rotation of the second wirerope 12, shape between two the second wirerope 12 and the first fixed block 7 respectively At triangle, the stability of the first fixed block 7 ensure that, then make hook 8 can only be under the traction of trolley 5, by the One wirerope 6 pulls the movement done vertically upward, ensure that stability of bridge crane during hoisting heavy, avoids Weight shakes in uphill process the appearance of situation, when needing before hoisting heavy, needs mobile trolley 5 horizontal When, one of electric telescopic rod 3 starts to extend, another electric telescopic rod 3 starts to shrink, and makes two sliding blocks 4 in sliding slot 2 Inside follows the variation of corresponding electric telescopic rod 3 respectively and moves, to drive the movement of two cabinets 9, makes two casees The distance between body 9 changes, and then drives the movement of hoist engine 10 and motor 11, and the horizontal of the second wirerope 12 is driven to move Dynamic, then the final movement for driving the hook on the first fixed block 7 repeats above-mentioned when cabinet 9 is moved to designated position The purpose lifted by crane on the different location of bridge crane to weight may be implemented in step.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
