Description
Technical field
The utility model relates to one kind of crane field to pull out shaft device, especially a kind of respectively to connect hinge for crane
The device of axis installation, it is particularly convenient for the installation of large scale, overweight hinge point shaft.
Background technique
Crane is that modern ships build industry realization production mechanization, the important tool of automation and equipment.With me
The continuous development of state's shipbuilding industry, shipbuilding technology, production technology also in the continuous improvement, lifting capacity, performance requirement to crane
Also it is improved constantly.3000T floating-crane ship is that the large size that our company designed, designed is built takes off bar crane, every
Performance indicator has all reached the front end of industry.This crane ship crane portion mainly include big cantilever crane, cantilever crane bracket, A-frame with
And the components such as engine house composition, the connection between cantilever crane and cantilever crane bracket, principal arm and auxiliary and each widget of A-frame itself
It is all made of hinge, to realize its work in every performance and technological design demand, and hinge shaft size is big, weight weight.And it cuts with scissors
Point installation is the important node that each component completes installation according to plan, and whether success or not determines to build can complete according to plan, project
It can deliver according to plan.
Currently, well known hinge point shaft mount scheme is generally by the way of tolling a bell, in the way of loop wheel machine and manpower cooperation
Installation, and without special Fixture Design, resource situation of each crane manufacturing enterprise according to itself enterprise, designed, designed in industry
Simple tooling, but the method operating difficulties, security risk are big, and cannot achieve to the installation of large scale, overweight pin shaft.
Utility model content
The utility model provides one kind and pulls out shaft device, which can be realized the installation of large scale, overweight hinge point shaft, uses
The device eliminates a large amount of human and material resources, has the characteristics that high-efficient, automatic, quick, and the type device is broadly applicable
There is the manufacturing enterprise of demand in each size.
Purpose of the utility model is realized as follows: one kind pulls out shaft device, including hydraulic pressure oil overhold support, hydraulic hollow oil
Top, bearing base and screw pair, bearing base are fixed on crane structure ontology by bolt arrangement, and hydraulic pressure oil overhold support is solid
It is scheduled on bearing base, is used to support and the hollow oil overhold of fixed hydraulic, the screw pair two nuts and spiral shell different by thickness
There are threaded hole in bar composition, pin shaft one end to be installed, and screw rod passes through hydraulic hollow oil overhold, bearing base, hinge hole and pin shaft spiral shell to be installed
Line connection, described two nuts are fixed on hydraulic pressure oil overhold support outer, and hydraulic hollow oil overhold is by pushing nut to drive screw rod, spiral shell
Bar drives pin shaft, realizes reversed drawing pin shaft.
Further, it is welded to connect between the oil overhold support and bearing base.
Further, described two nuts are hex nut.
Further, the lesser nut of thickness is set to outside.
The device of the utility model can realize different sizes by combining with different oil overhold equipment and different screw rods
The installation of specification axis, can be widely used for Crane Industry.
Detailed description of the invention

Specific embodiment
With reference to embodiments, more detailed description is done to the above-mentioned technical characteristic and advantage of the utility model.
One kind as shown in Figs. 1-3 pulls out shaft device, including hydraulic pressure oil overhold support 1, hydraulic hollow oil overhold 2,3 and of bearing base
Screw pair 4, bearing base 3 are fixed on crane structure ontology by bolt arrangement, the fixed card for borrowing structure itself of bolt
Axillare screw hole, hydraulic pressure oil overhold support 1 are fixed on bearing base 3, be used to support with the hollow oil overhold 2 of fixed hydraulic, such as Fig. 3 institute
Show, the screw pair 4 is made of different two hex nuts 41,42 of thickness and screw rod 43, and there is screw thread in 5 one end of pin shaft to be installed
Hole, screw rod are threadedly coupled across hydraulic hollow oil overhold 2, bearing base 3, hinge hole with pin shaft 5 to be installed, described two nuts 41,
42 are fixed on 1 outside of hydraulic pressure oil overhold support, and wherein the lesser nut 41 of thickness is set to outside, and hydraulic hollow oil overhold 2 is by pushing away
Dynamic nut 41,42 drives screw rod 43, screw rod 43 to drive pin shaft 5, realizes reversed drawing pin shaft.
First in place by axis lifting, hinge hole is inserted into one end, and screw rod rotation is fixed with axis, and then nut is screwed into oil overhold end,
Hydraulic pressure oil overhold work reversely pulls out axis by promotion nut, after completing an oil overhold stroke, oil overhold pressure release, and turn nut to oil overhold
End jacks again, successively works repeatedly, to realize the installation of axis to be worn.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those skilled in the art are practical to this
The various changes and improvements that novel technical solution is made should all be included in the protection model that the utility model claims book determines
In enclosing.
