Description
Technical field
The utility model relates to tower machine technology field, refers in particular to a kind of new type autoly to change multiplying factor device.
Background technology
Hoisting crane is a kind of important construction machinery and equipment in building operation.In order to take into account work efficiency and safety, present many hoisting cranes all have 2 multiplying powers and 4 multiplying powers, two kinds of mode of operation, like this, change between 2 multiplying powers and the mode of operation of 4 multiplying powers with regard to needing.Present most of hoisting cranes still adopt manual mode when carrying out the conversion of 2 multiplying powers and 4 multiplying powers, by the multiplying power conversion latch be fixed on hook assembly, multiplying power conversion pulley is controlled, it is made to carry out work when 2 multiplying power as fixed pulley, and carry out work when 4 multiplying power as movable pulley, and reach the conversion of 2 multiplying powers and 4 multiplying powers.In existing hoisting crane, if desired the conversion of multiplying power is carried out, then need first hoisting crane to be stopped, instrument is used to be unloaded by hook assembly by workman again, and the conversion latch of pulley is changed by multiplying power on manual handling hook assembly, realize the conversion of multiplying power, but this kind of mode is owing to needing adopt manual operation not only dangerous and have lower work efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, result of use good, the new type auto of low cost of manufacture changes multiplying factor device.
For achieving the above object, technical scheme provided by the utility model is: one is new type auto changes multiplying factor device, it includes back timber, base plate, axis, wherein, back timber is two, all channel-section steel is adopted to make shaping, article two, be connected and fixed by adapter plate between back timber top, the feet of " eight " font is provided with bottom back timber, feet bottom is provided with base plate, axis sleeve is installed in the middle part of adapter plate, axis upper cartridge is provided with bearing pin, axis lower cartridge is connected with axis one end downwards through adapter plate, the axis other end is connected with pressing plate through base plate vertically downward, be provided with positioning plate in the middle part of axis, positioning plate top is spacing by locating dowel pin, and the axis below positioning plate is set with spring, and spring top and positioning plate are conflicted, and the spacing ring on spring bottom and base plate is inconsistent.
After the utility model adopts such scheme, reach the object changing multiplying power by exerting pressure to positioning plate and spring, the structure of this programme is simple, result of use good, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model.
Fig. 2 is A-A cutaway view.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 to Fig. 2, the new type auto multiplying factor device that changes described in the present embodiment includes back timber 1, base plate 2, axis 3, wherein, back timber 1 is two, all channel-section steel is adopted to make shaping, article two, be connected and fixed by adapter plate 4 between back timber 1 top, the feet 5 of " eight " font is provided with bottom back timber 1, feet 5 bottom is provided with base plate 2, axis sleeve 6 is installed in the middle part of adapter plate 4, axis sleeve 6 top is provided with bearing pin 7, axis sleeve 6 bottom is connected with axis 3 one end downwards through adapter plate 4, axis 3 other end is connected with pressing plate 8 through base plate 2 vertically downward, be provided with positioning plate 9 in the middle part of axis 3, positioning plate 9 top is spacing by locating dowel pin 10, and the axis 3 below positioning plate 9 is set with spring 11, and spring 11 top and positioning plate 9 are conflicted, inconsistent with the spacing ring 12 on base plate 2 bottom spring 11.This device is with after such scheme, and reach the object changing multiplying power by exerting pressure to positioning plate and spring, the structure of this programme is simple, result of use good, low cost of manufacture.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
