Description
Technical field
The utility model relates to a kind of tower crane, specifically a kind of tower machine Suspension hook structure.
Background technology
Existing tower crane often adopts to be extractd multiplying power bearing pin and to hoist multiplying power to realize conversion on the hanging basket of loading trolley, suspension hook divides top sheave group and downslide wheels, multiplying power pinned connection is used in centre, when pulling out multiplying power bearing pin and top sheave group be fixed on loading trolley, top sheave group becomes fixed pulley, the lower suspension hook of work has two steel ropes, now suspension hook is 2 multiplying powers, when top sheave group and downslide wheels are with multiplying power pinned connection, whole suspension hook having four steel rope work, is four multiplying powers.In medium-and-large-sized tower machine, the size of suspension hook can be very large, and the distance stood between people on loading trolley hanging basket and multiplying power bearing pin can be far, is difficult to enough spaces and easily removes multiplying power bearing pin.
Usually two kinds of tower machine Suspension hook structure are had in prior art, one as shown in Figure 1, multiplying power bearing pin is in order to the convenient disassembly employing side band shaft shoulder, the mode that side is fixed with spring cotter, when upper and lower assembly pulley 1,2 is installed, must be squeezed into by bearing pin 3 in A side, then be penetrated in B side by spring cotter 4, installation personnel all must operate in the both sides of suspension hook.
As shown in Figure 2, bearing pin adopts the mode of both sides band cotter-pin hold to another kind of structure, and bearing pin 3 can be got to opposite side from the either side of A side or B side, but A side and B side must penetrate spring cotter 4 simultaneously, installation personnel all must operate in the both sides of suspension hook.
Above-mentionedly no matter adopt which kind of mode, operator must carry out operating in the both sides of axle just completing mounting or dismounting, and this requires that the distance between operator and suspension hook is enough near, has sufficient space to carry out the mounting or dismounting of bearing pin.Therefore prior art has following shortcoming:
1, install, dismantle inconvenience.Must again at opposite side construction opening pin after bearing pin is accomplished fluently in side.When the width of upper and lower assembly pulley is very large, people possibly cannot get at the opposite side of suspension hook on loading trolley, and at this moment multiplying power bearing pin just cannot be installed or dismantle, although or can install and there is certain potential safety hazard.
2, cannot prevent the rotation of axle, owing to not having the fixing of circumference to axle, therefore multiplying power bearing pin can freely rotate.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of tower machine Suspension hook structure, people is only operated in suspension hook side and just can easily install and remove multiplying power bearing pin, realize the change of tower machine multiplying power.
To achieve these goals, a kind of tower machine of the utility model Suspension hook structure, comprise top sheave group, downslide wheels and multiplying power bearing pin, described top sheave group and described downslide wheels are provided with corresponding connecting bore; Also comprise an axle sleeve, described multiplying power bearing pin is provided with cotter-pin hold on the shaft shoulder; Described axle sleeve is provided with corresponding cotter-pin hold, and axle sleeve is fixed on outside top sheave group or downslide wheels; When installing multiplying power bearing pin, multiplying power bearing pin penetrates the connecting bore of upper and lower assembly pulley from axle sleeve side, and when multiplying power bearing pin cotter-pin hold is concentric with the cotter-pin hold on axle sleeve, spring cotter inserts fixing.
As further improvement of the utility model, have outside described multiplying power bearing pin cotter-pin hold one for dismantling time pull the hole of multiplying power bearing pin, in this hole, an other column is as round steel, just multiplying power bearing pin can be extracted, easy to use.
As preferred version of the present utility model, described axle sleeve and top sheave group or lower sheave bond pads.Adopt the mode of welding, connection structure is more firm.
The utility model tower machine Suspension hook structure, the version of spring cotter fixed pin shaft both direction movement, operator only need can realize the conversion of multiplying power in the side of suspension hook, it has the following advantages:
1, version is simple, and production and processing is convenient, installation, convenient disassembly.Such version is simply effective, easily realizes the conversion of suspension hook multiplying power.
2, because operator just can to realize the conversion of multiplying power in side, when suspension hook size is larger, just can avoid can not getting at opposite side because operator's arm falls short of and can not magnification transformable being realized.
3, structure is provided with axle sleeve permanent opening pin and prevents the axial and circumferential of axle from moving.

Detailed description of the invention
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 3 and Figure 5, the utility model tower machine Suspension hook structure, comprises top sheave group 1, downslide wheels 2 and multiplying power bearing pin 3, and described top sheave group 1 and described downslide wheels 2 are provided with corresponding connecting bore; Also comprise an axle sleeve 5, described multiplying power bearing pin 3 is provided with cotter-pin hold on the shaft shoulder; Described axle sleeve 5 is provided with corresponding cotter-pin hold, axle sleeve 5 is fixed on outside top sheave group 1 or downslide wheels 2, what provide in accompanying drawing 3 here is be fixed in top sheave group 1, certainly if downslide wheels 2 are in the structure of outside lower sheave group 1 in interior survey, axle sleeve 5 just needs to be fixed on downslide wheels 2; When installing multiplying power bearing pin, multiplying power bearing pin 3 penetrates the connecting bore of upper and lower assembly pulley 1,2 from axle sleeve 5 side, and when multiplying power bearing pin 3 cotter-pin hold is concentric with the cotter-pin hold on axle sleeve 5, spring cotter 4 inserts fixing.Wherein, the connection mode of axle sleeve 5 and top sheave group 1 or downslide wheels 2, preferably welds here, and adopt the mode of welding, connection structure is more firm.
As shown in Figure 4, on said structure basis, also have outside multiplying power bearing pin 3 cotter-pin hold one for dismantling time pull the hole of multiplying power bearing pin 3.When by 4 magnification transformables to 2 multiplying power time, taken off by the spring cotter 4 of B side, multiplying power bearing pin 3 is an other round steel in the hole in outside, just multiplying power bearing pin can be extracted in B side with hand.
When installing multiplying power bearing pin 3, multiplying power bearing pin part 3 being squeezed into connecting bore from B side, when cotter-pin hold is concentric with the hole in sleeve member 5 inside multiplying power bearing pin part 3, the conversion of 2 multiplying powers to 4 multiplying powers can be completed in B side by also fixing for spring cotter insertion opening pin-and-hole.When by 4 magnification transformables to 2 multiplying power time, taken off by the spring cotter 4 of B side, multiplying power bearing pin 3 is an other round steel in the hole in outside, just multiplying power bearing pin can be extracted in B side with hand.
