Abstract
The utility model relates to a mining dump truck pin, and belongs to the technical field of mining dump trucks. The mining dump truck pin mainly solves the problem that an existing pin rotates due to torque and is difficultly disassembled and assembled. The mining dump truck pin is mainly characterized in that a pin body is a stepped shaft, axial threaded holes are formed in the head end and the tail end of the pin body respectively, the mining dump truck pin comprises a pin end cap, a rectangular hole is formed in the center of the pin end cap, bolt holes are formed in the periphery of the pin end cap, and a rectangular shaft section matched with the rectangular hole of the pin end cap is arranged at the head end of the pin body. The mining dump truck pin has the advantages that the pin is convenient to assemble and disassemble and can be effectively prevented from rotating due to torque, and the pin is mainly used for the mining dump trucks.
Description
Technical field
The utility model belongs to quarry tipper technical field.Be specifically related to a kind of quarry tipper bearing pin.
Background technique
Dumping car belongs to a kind of non-highway transport vehicle, general action is in large construction fields such as surface mine, port and pier, water conservancy and hydropowers, and its operating environment is severe, road is rugged, and also has overload serious, sudden turn of events load frequency high, causes the stressed complexity of car body to cause the stressed variation of bearing pin.
Bearing pin is as the carrier that bears transmission power and impact, and its operating mode more complicated, not only bears moment of flexure and also bear torque, thus prevent that the rotation of bearing pin from can prevent the wearing and tearing of pin shaft hole, to reduce maintenance and the replacing such as the component such as bearing pin, hangoff receptacle.
Whether the dismounting of hanging bearing pin facilitates is also the key factor that affects quarry tipper assembling and maintenance service.
Summary of the invention
The purpose of this utility model provides a kind of quarry tipper bearing pin for current quarry tipper pin shaft structure defect exactly, is subject to reverse moving and the difficult problem of dismounting to solve quarry tipper bearing pin.
For reaching above-mentioned purpose, technical solution of the present utility model is: a kind of quarry tipper bearing pin, comprise bearing pin body, and it is characterized in that: described bearing pin body is Step Shaft, and bearing pin body is respectively equipped with axial tapped hole in two ends end to end; Also comprise a bearing pin end cap, this bearing pin end cap center is provided with rectangular opening, is provided with bolt hole around; The head end of described bearing pin body is provided with the rectangle shaft part coordinating with bearing pin end cap rectangular opening.
The each shaft part of bearing pin body Step Shaft described in technical solution of the present utility model is provided with chamfering.
Between the each shaft part of bearing pin body Step Shaft described in technical solution of the present utility model, be provided with tool withdrawal groove.
The utility model is owing to adopting the bearing pin being made up of bearing pin body and bearing pin end cap, wherein, bearing pin body is Step Shaft, and bearing pin body end to end two ends is respectively equipped with axial tapped hole, bearing pin end cap center is provided with rectangular opening, be provided with bolt hole around, the head end of bearing pin body is provided with the rectangle shaft part coordinating with bearing pin end cap rectangular opening, thereby bearing pin can conveniently be installed and dismantle to the tapped hole at bearing pin two ends, effectively solve the problem of other pin assembling/disassembling difficulties, bearing pin end cap rectangular opening coordinates with bearing pin body rectangle shaft part, and bearing pin end cap is for fixing the bolt hole of himself, by bolt, bearing pin end cap is connected in to axis pin base, can effectively prevent that bearing pin is because being rotated by moment of torsion.The utility model is owing to being provided with chamfering at the each shaft part of bearing pin body Step Shaft, thereby is conducive to the assembling of bearing pin.The utility model is owing to being provided with tool withdrawal groove between the each shaft part of bearing pin body Step Shaft, thereby is not only conducive to the processing of bearing pin, also helps the location of other parts that are mated.The utlity model has convenient installation and dismounting and can effectively prevent the feature of bearing pin because rotated by moment of torsion.The utility model is mainly used in the bearing pin that quarry tipper hangs.
