Abstract
The utility model relates to an inflation round pin axle of usefulness is assembled to ocean module rig structure sled piece, characterized by: including sleeve, expansion valve, screw bolt and nut, expansion valve falls into four lamellas and the amalgamation becomes cylindrical, and cylindrical expansion valve's centre bore both ends are equipped with conical shaft hole respectively after the amalgamation, the bolt runs through to be controlled sleeve and expansion valve and screws through the nut. Beneficial effect: compared with the prior art, the utility model discloses replace formal round pin axle when assembling in advance, prevent to produce welding deformation between sled piece and the connecting plate, lead to round pin axle card to die the unable disadvantage of dismantling. Inflation round pin axle convenient and practical, interchangeability is good. Only need loosen the bolt during dismantlement, it expands just can easily to take out sells the axle, it is laborsaving to save labour.
Description
Technical field
The utility model belongs to welding accessory appliances, particularly relates to the expansion bearing pin that a kind of marine module drilling rig structure sled block is assembled.
Background technology
Adopt the marine drilling platform of little module building technology, the side of sled block and connecting panel is provided with otic placode, and otic placode is provided with pin shaft hole, and sled block and connecting panel by running through pinned connection on pin shaft hole.Build the side carry out pre-assembled time, need the relative position of accurately fixing every block sled block and connecting panel.The construction of marine rig is a great system engineering, and except steel structure has precise requirements, associated various pipelines etc. also have different accuracy requirements.Prize block in installation process to weld with connecting panel and often welding deformation can occur, cause the bearing pin be applied in pin shaft hole stuck, cannot be for convenience detach after causing prepackage to complete.Marine drilling platform construction urgently release a kind of can in the pre-assembled epoch for the plug bearing pin that rises of formal bearing pin, to solve between sled block and connecting panel welding deformation by problem stuck for bearing pin
Utility model content
The utility model is to overcome deficiency of the prior art, a kind of marine module drilling rig structure is provided to prize the assembled expansion bearing pin of block, in the pre-assembled epoch for formal bearing pin, prevent from producing welding deformation between sled block and connecting panel and bearing pin is stuck, for Assembly &Disassembly work is provided convenience.
The utility model for achieving the above object, be achieved through the following technical solutions, the expansion bearing pin that a kind of marine module drilling rig structure sled block is assembled, it is characterized in that: comprise sleeve, expanding petal, screw bolt and nut, described expanding petal is divided into pintongs and pieces together cylindrical, after split, the centre hole two ends of cylindrical expanding petal are respectively equipped with conical axis hole, and described bolt-through left and right sleeve and expanding petal also pass through nut.
Described sleeve is divided into left and right sleeve, and excircle of sleeve is conical, and mates with the conical axis hole of expanding petal.
Described left and right sleeve two side ends is provided with clamping washer.
Beneficial effect: compared with prior art, the utility model pre-assembled time substitute formal bearing pin, prevent sled block and connecting panel between produce welding deformation, cause bearing pin stuck, the disadvantage that cannot dismantle.Expansion bearing pin is convenient and practical, and interchangeability is good.Only need unclamp bolt during dismounting, just easily can take out expansion bearing pin, save labor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the expanding petal in Fig. 1.
In figure: 1, sleeve, 2, expanding petal, 3, bolt, 4, nut, 5, clamping washer.
Detailed description of the invention
Below in conjunction with preferred embodiment, to the detailed description of the invention provided according to the utility model, details are as follows: embodiment
Refer to accompanying drawing, present embodiments provide the expansion bearing pin that a kind of marine module drilling rig structure sled block is assembled, comprise sleeve 1, expanding petal 2, bolt 3 and nut 4, described expanding petal can be divided into pintongs and piece together cylindrical, after split, the centre hole two ends of cylindrical expanding petal are respectively equipped with conical axis hole, and described bolt-through left and right sleeve and expanding petal also pass through nut.Described sleeve is divided into left and right sleeve, and excircle of sleeve is conical, and mates with the conical axis hole of expanding petal.Described left and right sleeve two side ends is provided with clamping washer 5.The making of expanding petal: car goes out cylinder, middle car circular hole, and process the conical bore at two ends, after completing, with milling machine, just it mills out four pieces of expanding petals again.
Working process
Pre-assembled time, adjust the position of sled block and connecting panel, first connecting panel is spoted weld on main structure sled block, then the left sleeve of expanding petal and bolt cap side is pierced in the pin shaft hole of otic placode, keep expanding petal in pin shaft hole, again from opposite side by right sleeve set on bolt, then pad and bolt tightening is used, along with tightening of bolt, two ends sleeve moves closer to, expanding petal then can radially outward move, until combine closely with the pin shaft hole on otic placode, substitute the relative position of fixing structure for pin shaft sled block and connecting panel, and then connecting panel is welded on main structure sled block, prevent welding deformation, only bolt need be unclamped during dismounting, just can easily take out expansion bearing pin, dismantle very convenient.
The detailed description that the above-mentioned expansion bearing pin assembled to this kind of marine module drilling rig structure sled block with reference to embodiment carries out; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under the utility model general plotting and amendment, should belong within protection domain of the present utility model.
Claims (3)
1. the expansion bearing pin that a marine module drilling rig structure sled block is assembled, it is characterized in that: comprise sleeve, expanding petal, screw bolt and nut, described expanding petal is divided into pintongs and pieces together cylindrical, after split, the centre hole two ends of cylindrical expanding petal are respectively equipped with conical axis hole, and described bolt-through left and right sleeve and expanding petal also pass through nut.
