The utility model content
The utility model is intended to address the above problem, provide a kind of fracturing pump car owner subframe to flexibly connect assembly, it is rational in infrastructure, easy for installation, practical, and can make between the fracturing pump car owner subframe simultaneously has restricted relative motion, and its technical scheme that adopts is as follows:
A kind of fracturing pump car owner subframe flexibly connects assembly, comprises upper connector, tie bolt and lower attaching parts;
Described upper connector comprises left L shaped wing plate, upper connector connecting panel and right L shaped wing plate; The L shaped wing plate in a described left side and right L shaped wing plate all are welded on the subframe, and described upper connector connecting panel and left L shaped wing plate, right L shaped wing plate and subframe are welded in one and between the L shaped wing plate in a left side and right L shaped wing plate;
Described lower attaching parts comprises attaching parts connecting panel under the shape of a hoof, the base plate that has tapped bore and binding bolt, described upper connector connecting panel and lower attaching parts connecting panel are by the tie bolt detachable connection, described base plate and the mutual vertical welding of lower attaching parts connecting panel are in one, and described base plate is by binding bolt and main car frame detachable connection.
On the technique scheme basis, to go back rigid connecting between the L shaped wing plate in a described left side and the right L shaped wing plate and be connected to reinforced plate, described reinforced plate is welded in subframe.
On the technique scheme basis, have the welding circular hole on the described reinforced plate.
On the technique scheme basis, described lower attaching parts also comprises reinforced rib, and described reinforced rib and lower attaching parts connecting panel and base plate are welded in one, and wherein the end face that welds mutually with lower attaching parts connecting panel of reinforced rib and the end face that welds mutually with base plate are perpendicular.
On the technique scheme basis, described reinforced rib is triangle.
The utlity model has following advantage: can therefore can reduce the stress concentration phenomenon of major-minor bicycle frame superposed surfaces so that restricted micro-relative motion is arranged between the fracturing pump car owner subframe, increase the service life of vehicle frame, simultaneously easy for installation, practical.
