Abstract
The invention discloses a high-powered crawler type bulldozer S-shaped oil tube mounting structure which is used for positioning the upper end of S-shaped oil tubes in a steering pipeline when a high-powered crawler type bulldozer is assembled. A seat plate, a bearing seat, an S-shaped oil tube, a retainer and a steering valve are assembled sequentially; the retainer is embedded into two small grooves of the seat plate for positioning; and the upper end of the left S-shaped oil tube and the upper end of the right S-shaped oil tube penetrate through the retainer to be positioned. When the position between the steering valve and the seat plate is aligned with a mounting hole, a left oil outlet and a right oil outlet of the steering valve are respectively aligned with the upper end of the left S-shaped oil tube and the right S-shaped oil tube, the oil outlet aligning process is simplified when the steering valve is assembled, the damage of an O-ring sleeved on the upper ends of the S-shaped oil tubes can be avoided effectively in the mounting and aligning process, and the reliability of the high-powered bulldozer can be improved.
Description
Technical field
The present invention relates to a kind of device that the high-power crawler dozer keeps S shape oil pipe installation site that is used for, relate in particular to a kind of high-power crawler dozer that is used for and turn to fixedly S shape oil pipe upper end mounting structure of pipeline.
Background technology
At present, the known domestic and international high-power crawler dozer method that turns in the pipeline S shape oil pipe that flows to steering cluth from switching valve all to adopt pipe clamp that left S shape oil pipe and right S shape oil pipe are clamped is simultaneously fixed.When follow-up assembling switching valve and/or maintenance dismounting switching valve; The left and right S shape oil pipe upper end mouth of pipe could be installed switching valve after must aiming at and being positioned at two spill oil-outs in switching valve bottom and insertion smoothly; But; The left and right S shape oil pipe upper end mouth of pipe only connects fixing with pipe clamp; Can't confirm in advance and the left and right S shape oil pipe upper end nozzle position of two spill oil-outs installation site, switching valve bottom coupling that the assembly crewman is difficult to two oil-outs in switching valve bottom are aimed at the left and right S shape oil pipe upper end mouth of pipe.In alignment procedures, destructive envelope produces oil leakage phenomenon at the O shape circle of S shape oil pipe upper end easily, causes bulldozer malfunctioning fault in the operation driving process, to occur turning to.
Summary of the invention
Technical problem to be solved by this invention is; Overcome the problem that exists in the prior art; A kind of high-power crawler dozer S shape oil pipe mounting structure is provided, and this structure can guarantee that two the spill oil-outs in switching valve bottom accurately aim at the left and right S shape oil pipe upper end mouth of pipe when mounted.
In order to address the above problem technical scheme of the present invention is such:
Cancel original pipe clamp; A kind of high-power crawler dozer S shape oil pipe mounting structure comprises left and right two S shape oil pipes, and mate with the installation site at two spill oil-out centers of switching valve bottom left and right two S shape oil pipes upper end; The bearing support oil-in is inserted in left and right two S shape oil pipe lower ends; It is characterized in that left and right two S shape oil pipes upper end mouth of pipe is provided with the retainer of a location, is useful on two through holes that S shape oil pipe passes on the retainer; Retainer embeds and is installed on the seat board of a switching valve, and seat board is through being bolted on the rear axle box.
Two through holes of retainer are vertically passed in left and right two S shape oil pipes upper end, and the through hole on the retainer all overlaps with left and right two S shape oil pipes upper end center line.
The both sides of retainer are provided with two alices, and seat board is provided with the sulculus that is used to embed alice.
The invention has the beneficial effects as follows; The hydraulic fluid port alignment procedures shortens installation time when simplifying the switching valve assembling, and retainer is simple in structure; Fitting operation is easy; Can effectively avoid the O shape circle of destructive envelope on S shape oil pipe in the installing and aligning process, thereby reduce malfunctioning fault appears turning in the high-power bulldozer in the operation driving process probability, improve high-power bulldozer reliability.
