In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The utility model aims at the not enough of prior art to a semitrailer pneumatic lift draw gear of seat height-adjustable, the sound construction is stable, the different situation vehicle of adaptation is pull is provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a pneumatic lift draw gear of semitrailer, includes load-bearing panel, at least one cylinder, at least a set of guide bar and a traction seat mounting panel, load-bearing panel fixes on the frame, the cylinder body of cylinder is vertical to be fixed load-bearing panel is last, the post of the cylinder sets up downwards, load-bearing panel is last to center on the cylinder body of cylinder is equipped with a set of vertical uide bushing, each during the guide bar one-to-one penetrates each uide bushing, the post lower extreme of the post of cylinder, the lower extreme of each guide bar with traction seat mounting panel is fixed.
Basically, each cylinder is correspondingly provided with two guide rods and two guide sleeves, and the two guide rods and the two guide sleeves are respectively arranged on two sides of the cylinder.
Basically, the bearing panel is provided with a cylinder fixing seat for installing a cylinder, and the cylinder body of the cylinder is installed on the cylinder fixing seat.
On the basis, the bearing panel is provided with a right-angle plate corresponding to the guide sleeve, one side edge of the right-angle plate is welded and fixed on the cylinder fixing seat, the other side edge of the right-angle plate is parallel to the bearing panel, the upper part of the guide sleeve is welded and fixed with the other side edge of the right-angle plate, and the lower part of the guide sleeve is welded and fixed with the bearing panel.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses increase one set of cylinder and guider for the height of seat mounting panel is pull in control, and then the adjustment and the matching of seat height are pull under realizing different situations, avoid because of the semitrailer loading end slope that the high difference of front and back vehicle leads to, goods slope and the unbalanced axle atress that arouses of axle tire damage scheduling problem unusually, it has the advantage of pulling seat height-adjustable, the sound construction is stable, the different situations vehicle of adaptation.

In the figure: 1. a load bearing panel; 2. a cylinder; 2-1, cylinder body; 2-2, a plunger; 3. a guide bar; 4. a traction seat mounting plate; 5. a frame; 6. a guide sleeve; 7. a right-angle plate; 8. cylinder fixing base.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1-4, a pneumatic lifting traction device for a semitrailer includes a bearing panel 1, two cylinders 2, two sets of guide rods 3 and a traction seat mounting plate 4, wherein the bearing panel 1 is fixed on a frame 5, the bearing panel 1 is provided with a cylinder fixing seat 8 for mounting the cylinders 2, a cylinder body 2-1 of each cylinder 2 is vertically fixed on the cylinder fixing seat 8, a movable column 2-2 of each cylinder 2 is arranged downward, a pair of vertical guide sleeves 6 are arranged on the bearing panel 1 and located on two sides of the cylinder body 2-1 of each cylinder 2, each guide rod 3 correspondingly penetrates into each guide sleeve 6, and the lower ends of the movable columns 2-2 and the guide rods 3 of the cylinders 2 are fixed to the traction seat mounting plate 4.
In order to ensure the stability of the guide column, a right-angle plate 7 is arranged on the bearing panel 1 corresponding to the guide sleeve 6, one side edge of the right-angle plate 7 is welded and fixed on the cylinder fixing seat 8, the other side edge of the right-angle plate 7 is parallel to the bearing panel 1, the upper portion of the guide sleeve 6 is welded and fixed with the other side edge of the right-angle plate 7, and the lower portion of the guide sleeve 6 is welded and fixed with the bearing panel 1.
Description of the working principle: the traction seat is installed on the traction seat mounting plate 4, when the vehicle load is too big or the vehicle specification does not match the situation, the flexible volume of control cylinder 2, the distance between adjustment traction seat mounting plate 4 and load-bearing panel 1, with the altitude mixture control of traction seat to match with the tractor, then connect again, control the semitrailer loading end and be in the horizontality, can effectively avoid the semitrailer loading end to appear inclining, solve the different axle tire abnormal damage's that leads to of each axle atress of semitrailer problem.
In the traction process, the guide rods 3 can avoid the inclination phenomenon in the lifting process, the purpose of the guide rods 3 is to strengthen the structure, the stress transmission of the traction seat mainly depends on the guide rods 3 instead of the movable columns 2-2 of the air cylinder 2, and the movable columns 2-2 are protected from deformation.
