Abstract
The utility model discloses an S-shaped oil pipe mounting structure for high-horsepower crawler type bulldozers, which is used for positioning the upper end of the S-shaped oil pipe in a steering pipeline during the installation of high-horsepower crawler type bulldozers. According to the structure, a seat board, a bearing seat, S-shaped oil pipes, a retainer and a steering valve are successively assembled. The retainer is embedded inside the two small grooves of the seat board to be positioned. The upper ends of the left and right S-shaped oil pipes pass through the two through holes of the retainer to be positioned. When the installing hole of the steering valve is aligned with that of the seat board, the left and right oil outlets of the steering valve are respectively aligned with the upper ends of the left and right S-shaped oil pipes. Therefore, the oil outlet aligning process during the installation of the steering valve is simplified and O-shaped rings sleeved on the upper ends of the S-shaped oil pipes are effectively prevented from being damaged during the installation and aligning process. Meanwhile, the reliability of high-horsepower bulldozers is improved.
Description
Technical field
The utility model relates to a kind of device that the high-power crawler dozer keeps S shape oil pipe installation site that is used for, and relates in particular to a kind of high-power crawler dozer that is used for and turns 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 is connected and fixed with pipe clamp, can't determine 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 to occur turning in the operation driving process.
The utility model content
Technical problem to be solved in the utility model is, overcome problems of 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 the technical solution of the utility model is such:
Cancel original pipe clamp, a kind of high-power crawler dozer S shape oil pipe mounting structure, comprise left and right two S shape oil pipes, 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, be 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 by 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 beneficial effects of the utility model are, hydraulic fluid port alignment procedures when simplifying the switching valve assembling, shorten installation time, retainer is simple in structure, fitting operation is easy, can effectively avoid installing the O shape circle of destructive envelope on S shape oil pipe in the alignment procedures, thereby reduce malfunctioning fault appears turning in the high-power bulldozer in the operation driving process probability, improve high-power bulldozer reliability.
