Preferably, it is connected between the fixed plate and mounting groove by trip bolt.

Preferably, it is fixedly connected by welding between the reinforcement steel plate and outer U-type groove steel and interior U-type groove steel.

Preferably, the stent is an integral molding structure with fixed plate.

Preferably, the stent and supporting leg are trapezoidal shape structure.

Compared with prior art, the beneficial effects of the invention are as follows:

1st, the present invention is by the first connecting plate and the second connecting plate of setting, and girder is by the first connecting plate and the second connecting plate Outer framework is formed, and Bailey bracket is installed between the first connecting plate and the second connecting plate, both instead of the main beam structure of conventional cumbersome, Frame deformation is also avoided simultaneously, is prolonged the service life.

2nd, the present invention is by the stent and supporting leg of setting, and general supporting leg is flower holder structure, load bearing effect difference and itself compared with Weight, stability is not high, this kind of door frame forms trapezoidal shape stent, and interior U-type groove steel and outer U-type groove steel quality by trapezoidal shape supporting leg It is relatively light, stable connection.

3rd, for the present invention by the bottom end rail and mounting groove of setting, bottom end rail is load-bearing basic part, is fitted with crane fortune Row mechanism makes door machine orbiting, and fixed plate is connected in mounting groove by trip bolt, and handling are convenient.
