the utility model discloses in, adopt two hinge block hinge dress to connect and form the wheel carrier. When the pin shaft is in a penetrating state, the relative angle of the two hinge blocks is fixed through the pin shaft pin and is in a high-position state. Because the travelling wheels arranged at the lower ends of the two hinge blocks are tightly pressed with the ground, when the pin shaft is in a pulled-out state, an included angle formed by the two hinge blocks is increased under the action of self weight until the bottom of the frame is contacted with the ground, and the frame is in a low-position state. Not only can realize the lifting of the frame, but also can realize the two-point positioning of the frame. The method overcomes the defects of the prior art through reasonable structural design, does not need complex design and process on the basis of meeting the requirement of realizing the lifting of the frame, and has low cost and high practicability.
The utility model discloses in, the frame adopts one side open-ended rectangle structure, and its one side is passed through the traction lever and is connected with outside tractor, and the opposite side then is used for the undercarriage to pull.
The utility model discloses in, four jacking cylinders are used for lifting and descending the frame under the state of stewing, and after in the undercarriage was pulled the frame, it can wear the dress round pin axle after carrying out the jacking and fix the wheel carrier.
The utility model discloses in, the domatic and the installation of capstan winch that the bottom plate was made are all in order to guarantee that undercarriage traction process's is stable smooth-going.

Detailed Description
The present invention is described in detail below with reference to examples, which are illustrative and not restrictive, and the scope of the invention is not limited thereto.
The utility model provides a undercarriage of frame liftable removes uses trailer, includes a frame 5, the utility model discloses an innovation lies in, the frame is installed many pairs of wheel carriers along length direction in order, and every two internal wheel carrier symmetries are installed in the width both sides of frame, every the wheel carrier all includes two hinge blocks 3, and these two hinge blocks homonymy tip is connected through 4 hinges of a hinge, and advancing wheel 6 is installed respectively at the both ends of carrying on the back mutually, and these two advancing wheels form "triangle-shaped" structure with the hinge, and two advancing wheel positions are the base angle of this "triangle-shaped", a round pin axle has been worn to two hinge blocks position that lie in the hinge side, and this round pin axle is parallel with the hinge, round pin axle and hinge block movable mounting, its both sides tip are worn out by two hinge blocks respectively.
In this embodiment, the frame is rectangular, a drawbar 8 is mounted at one end of the frame, an opening 10 is formed at the other end of the frame, a baffle 2 is movably mounted at the opening, and two ends of the baffle are respectively fixed with two ends of the frame through a longitudinal pin 1.
