As a preferred technical scheme:
the hydraulic trailer equipment for the A-shaped frame is characterized in that the top shaft is vertically arranged.
The hydraulic trailer equipment for the A-shaped frame is characterized in that the pressure relief handle is arranged on the pressure bar.
The hydraulic trailer equipment for the A-shaped frame further comprises an elastic reset element, and the elastic reset element is used for overcoming the resistance of residual pressure and driving the small top shaft to be lowered to the lowest point when the small top shaft is decompressed; when the pressure is relieved, the pressure is difficult to be completely removed, the small top shaft is difficult to be lowered to the lowest point due to the residual pressure, and cannot be removed from the supporting ring of the A-shaped frame, and the problem can be effectively solved due to the arrangement of the elastic resetting element.
In the hydraulic trailer equipment for the A-shaped frame, the elastic reset element is a tension spring, one end of the tension spring is fixedly connected with the frame, the other end of the tension spring is fixedly connected with the middle part of the supporting arm, and an area enclosed by the tension spring, the frame and the supporting arm is triangular; the utility model discloses can release the residual pressure with the help of the tension of extension spring for little apical axis is fallen to the minimum fast after the pressure release.
According to the hydraulic trailer equipment for the A-shaped frame, the number of the main bearing wheels is two, and the bearing size of the main bearing wheels is 3 tons or more.
The hydraulic trailer equipment for the A-shaped frame further comprises more than one heavy universal caster, and the heavy universal caster is installed below the left side of the frame; the gravity centers of all main bearing wheels and all heavy universal caster wheels are not on the same straight line simultaneously, so that the trailer can be effectively prevented from inclining.
As above-mentioned hydraulic pressure trailer equipment for A cabinet frame, the position of little apical axis satisfies: when the small top shaft rises to the highest point, the vertex of the small top shaft is positioned between the main bearing wheels and the heavy universal caster and is 10-15 mm away from the midpoint of the connecting line of the centers of the two main bearing wheels, and the design that the A-shaped frame is heavy can effectively stabilize the gravity center of the hydraulic trailer and prevent the hydraulic trailer from tilting forwards.
It should be noted that the terms "left", "right", etc. in the present invention only represent the orientation of the term in the normal use state, and the description is made for the convenience of those skilled in the art to accurately understand the structure of the hydraulic trailer device for the a-frame, and should not be construed as limiting the term.
Advantageous effects
The utility model discloses a hydraulic pressure trailer equipment for A cabinet frame, it is convenient to remove, and stability can be good, can not take place potential safety hazards such as rocker hired roughneck, can eliminate potential danger, and the staff uses reassurance.
