Abstract
The utility model discloses a kind of tower machine cat ladder fast mounting structure, comprise otic placode (1) and cat ladder (7), cat ladder is provided with hook (6), also comprises fixed bearing (2), bearing pin (3) and spring cotter (4); Fixed bearing upper end is provided with cover of wedge (5), and fixed bearing is linked together by bearing pin and otic placode, hangs among cover of wedge, and installs spring cotter in the hook portion front end of hook.Beneficial effect is: cat ladder fast mounting structure improves traditional bolt connecting mode, is improved to pinned connection and is connected with cover of wedge.In fast mounting structure, cat ladder hook is connected with fixed bearing cover of wedge, easy for installation, quick; And the cat ladder handling inconvenience that effectively prevent because bolt corrosion causes.
Description
Technical field
The utility model relates to a kind of tower machine, and specifically a kind of tower machine cat ladder fast mounting structure, belongs to tower machine cat ladder field.
Background technology
Tower crane, is called for short tower machine, is mainly used in the horizontal and vertical transport of housing construction material and the installation of building and large-sized mechanical component.Tower machine can be divided into three kinds by installation form: jack up, overall fast assembling-disassembling and pin-connected panel.And the cat ladder of tower machine, be all a component part that must not lack in which kind of installation form.Specifically, the Main Function of tower machine cat ladder is engaged in operation, maintenance, inspection and the designated lane of repair tower machine for person skilled.
But in existing tower machine cat ladder mounting structure design, it is that the form be bolted realizes that cat ladder is installed.On the one hand, on cat ladder, the fitted position of bolt connecting hole requires higher, if directly get out assembly opening in cat ladder manufacturing process, easily occur the situation of not installing, after needing to determine position during general assembly, scene gets out; On the other hand, need other people to coordinate when bolt is installed, installation effectiveness is also lower.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of tower machine cat ladder fast mounting structure, can reduce the size tolerance requirements of mounting hole, a people also can be made to complete installation separately, increase work efficiency, and reduces cost of installation.
To achieve these goals, the technical solution adopted in the utility model is: a kind of tower machine cat ladder fast mounting structure, comprises one-time formed otic placode, described otic placode is fixedly connected with two fixed bearings, described fixed bearing is provided with bearing pin, and bearing pin one end is provided with cover of wedge; Described bearing pin is arranged on fixed bearing at a certain angle, and described bearing pin is provided with through hole; Be provided with " L " type hook in described cover of wedge, described hook one end is connected with cat ladder, and the other end termination of described hook is provided with spring cotter; Described fixed bearing is welded on described otic placode by two legs, is fixedly welded with tripod between two leg; Described bearing pin is provided with the spring with flexure stress being placed on described bearing pin.
Further, described welding hook is in the girder of described cat ladder, and described hook is welded on described cat ladder by claw.
Further, the spring on described bearing pin is fastened in the through hole on described bearing pin by buckle.
The beneficial effects of the utility model are: from Assembly &Disassembly angle, simple and quick, do not need other people to coordinate, and the tolerance on fit of cover of wedge on cat ladder fixed bearing and hook are large, are easy to produce, reduce costs.And bearing pin is arranged on fixed bearing at a certain angle, the area of contact between bearing pin and fixed bearing can be increased, make its contact more firm.And in fixed bearing, tripod is installed, increases its steadiness.Cat ladder fast mounting structure improves traditional bolt connecting mode, is improved to pinned connection and is connected with cover of wedge.In fast mounting structure, cat ladder hook is connected with fixed bearing cover of wedge, easy for installation, quick; And the cat ladder handling inconvenience that effectively prevent because bolt corrosion causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, otic placode, 2, fixed bearing, 3, bearing pin, 4, spring cotter, 5, cover of wedge, 6, hook, 7, cat ladder, 8, tripod, 9, spring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of tower machine cat ladder fast mounting structure, comprise one-time formed otic placode 1, described otic placode 1 is fixedly connected with two fixed bearings 2, described fixed bearing 2 is provided with bearing pin 3, bearing pin 3 one end is provided with cover of wedge 5; Described bearing pin 3 is arranged on fixed bearing 2 at a certain angle, and described bearing pin 3 is provided with through hole; Be provided with " L " type hook 6 in described cover of wedge 5, described hook 6 one end is connected with cat ladder 7, and the other end termination of described hook 6 is provided with spring cotter 4; Described fixed bearing 2 is welded on described otic placode 1 by two legs, is fixedly welded with tripod 8 between two leg; Described bearing pin 3 is provided with the spring 9 with flexure stress being placed on described bearing pin 3.Described hook 6 is welded in the girder of described cat ladder 7, and described hook 6 is welded on described cat ladder 7 by claw.Spring 9 on described bearing pin 3 is fastened in the through hole on described bearing pin 3 by buckle.Bearing pin 3 is provided with spring, can protect bearing pin 3 longer service life some.
During installation, two hooks 6 being positioned at the same side are hung over the cover of wedge 5 be positioned on fixed bearing 2, then, has through hole in hook 6 hook portion front end, spring cotter 4 is arranged in hook 6 through hole, prevent hook 6 from breaking off relations.Cover of wedge 5 and hook 6 can have relatively large tolerance on fit, are easy to handling.By the application of this technology, the installation of cat ladder in XGT100 tower machine, the convenient of dismounting change, when effectively reducing carman.
Cat ladder fast mounting structure improves traditional bolt connecting mode, is improved to bearing pin 3 connection and is connected with cover of wedge 5.In fast mounting structure, cat ladder hook 6 is connected with fixed bearing cover of wedge 5, easy for installation, quick; And the handling that effective anti-bolt corrosion causes are inconvenient.
