The utility model has the advantages of simple structure, non metallic bearing reliable operation degree is high, and it is convenient to maintain.
Description
Technical field
This utility model relates to technical field of crane equipment, particularly relates to a kind of general's column crane upper bearing structure.
Background technology
General's column crane is on ocean platform, boats and ships during operation, and its upper bearing structure needs to bear axial load and radial load simultaneously.Bearing arrangement herein, work operating mode and force-bearing situation are severe, and abrasion condition is serious.
At present, general's column crane upper bearing structure species is more, mainly has solid box formula, metal thrust bearing and nonmetal journal bearing combination type etc..Crane is when normal operation, and environmental working condition is severe, and metal thrust bearing easily weares and teares and relatively costly, and solid box formula is changed difficult in maintenance upon wear.
Summary of the invention
The purpose of this utility model is to provide a kind of general's column crane upper bearing structure, solves metal thrust bearing cost height present in prior art, quick abrasion；Solid box formula regular maintenance difficulty, installs and changes the problems such as complexity.
This utility model be employed technical scheme comprise that, a kind of general's column crane upper bearing structure, including kingpost, is welded on the stigma pin of kingpost body upper end, portal gantry, bearing keeps seat, connecting bolt, cod, journal bearing, journal bearing locating piece；
Bearing keeps seat and portal gantry, connects by connecting bolt is fixing；
Stigma pin and bearing keep being separately installed with cod and journal bearing between seat；
Cod lower surface has the first locating slot, and the first described locating slot is corresponding with the first locating piece of stigma pin upper surface to be installed；Journal bearing outer surface has the second locating slot, and the second described locating slot keeps the corresponding installation of the second locating piece of base inner surface with bearing, and journal bearing passes through journal bearing locating piece axial restraint simultaneously；
Described cod and journal bearing are respectively equipped with the first grease channel and the second grease channel.
Preferably, described cod and journal bearing are nylon material.
Of the present utility model have the beneficial effect that
1. when crane normally works, described cod bears the axial load of vertical direction, and described journal bearing bears the radial load of horizontal direction, and stress load situation is improved.
2. cod described in and journal bearing all use the nonmetallic materials of high-wearing feature and high intensity, while ensureing bearing strength, in turn ensure that nonmetal during crane rotation and the wearability of metal material relative motion.
3. stigma pin upper surface described in is provided with the first locating piece, and described bearing keeps base inner surface to be provided with the second locating piece, facilitates described cod and the installation of journal bearing, positions and retrain.
4. bearing described in keeps seat to be connected by described connecting bolt and described portal gantry, after crane works a period of time, there is abrasion in described cod and journal bearing, by removing described connecting bolt, described bearing holding seat can be taken off, and change bearing therein, and simple in construction, convenient for installation and maintenance.
Accompanying drawing explanation
Fig. 1 is this utility model a kind of general column crane upper bearing structure installation site schematic diagram on crane；
Fig. 2 is this utility model one general's column crane upper bearing structural representation.
In figure, 1. stigma pin, 2. portal gantry, 3. bearing keeps seat, 4. connecting bolt, 5. cod, 6. journal bearing, 7. kingpost, 8. journal bearing locating piece, 9. the first grease channel, 10. the second grease channel, 11. general's column crane upper bearing structures.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, kingpost crane upper bearing structure 11 of the present utility model is arranged on kingpost 7 upper end of general's column crane, is connected by connecting bolt 4 and portal gantry 2.
With reference to Fig. 2, described general's column crane upper bearing structure includes, is welded on the stigma pin 1 of kingpost 7 upper end, and stigma pin 1 upper surface is provided with the first locating piece；
Bearing keeps seat 3 inner surface to be provided with the second locating piece, and is connected by connecting bolt 4 and portal gantry 2；
Bearing keeps being provided with cod 5 and journal bearing 6 between seat 3 and stigma pin 1, cod 5 lower surface has the first locating slot, upper surface has the first oil-way, install fixing by the first locating piece of the first locating slot and stigma pin 1 upper surface, during crane rotation, cod 5 is fixed on stigma pin 1 upper surface and remains stationary as；Journal bearing 6 outer surface has the second locating slot, inner surface has the second oil-way, the second locating piece of seat 3 inner surface is kept to install by the second locating slot and bearing fixing, journal bearing 6 is by journal bearing locating piece 8 axial restraint simultaneously, during crane rotation, journal bearing 6 keeps seat 3 to rotate around stigma pin 1 with bearing；
Journal bearing locating piece 8 is arranged on bearing by screw and keeps on seat 3；
Can keep adding between seat 3 grease to cod 5 and bearing by the first grease channel 9, grease can be saved in the first oil-way；Can also be by the second grease channel 10 to adding grease between journal bearing 6 and stigma pin 1, grease can be saved in the second oil-way.
Cod 5 and journal bearing 6 all use the nylon material of high-strength, high-anti-friction, have stronger antiwear property and bearing capacity, can realize good relative slip, it is ensured that the carrying of crane and cornering rate.
This practical new operation principle is,
1. portal gantry 2 keeps seat 3 to connect by connecting bolt 4 and bearing, bearing keeps being provided with cod 5 and journal bearing 6 between seat 3 and stigma pin 1, cod 5 is arranged on stigma pin 1 upper surface by the first locating slot and the first locating piece and bearing keeps seat 3 to constitute kinematic pair, journal bearing 6 is arranged in bearing keeps seat 3 by the second locating slot and the second locating piece and stigma pin 1 constitutes kinematic pair, it is achieved portal gantry 2 keeps together with seat 3 around kingpost 7 and stigma pin 1 gyration with bearing.
2. keep injecting between seat 3 grease by the first grease channel 9 to cod 5 and bearing；By the second grease channel 10 to injecting grease between journal bearing 6 and stigma pin 1.The frictional force between relative motion feature can be reduced, improve work efficiency, reduce the abrasion of bearing.
3. after crane works a period of time, cod 5 and journal bearing 6 occur when abrasion needs to change, have only to bearing keeps the connecting bolt 4 between seat 3 and portal gantry 2 remove, bearing keep seat 3 and stigma pin 1 separate, remove journal bearing locating piece 8, just can take out cod 5 and journal bearing 6 is replaced.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
