Detailed Description

The present invention will be described in further detail with reference to specific examples, which are intended to be illustrative rather than restrictive.

Examples

The utility model provides a hoist and mount auxiliary device convenient to bridge is dismantled, including rectangle hoisting point 1, hole 2, bearing bar 3, separation blade 4, jib 5, girder 6.

The surface of the bearing rod 3 is full of threads, and a circular hole is formed in the center of the baffle 4 and threads are formed in the inner part of the baffle. Girder 6 is along the horizontal drilling of cross section direction, respectively punches and link up at 6 both ends of girder, respectively with the drilling at 6 bottom both ends of girder of two bearing bars 3 traversing respectively, bearing bar 3 adopts two in this embodiment, can increase the quantity of bearing bar 3 according to girder 6 during the use, and bearing bar 3 adopts the stainless steel to make.

The bearing rod 3 is provided with separation blades 4 at two sides of the main beam, and the separation blades 4 fix the main beam 6 on the bearing rod 3 through the mechanical meshing action between the threads. After the installation is completed, the suspension rods 5 are installed at the two ends of the bearing rod 3, the suspension rods 5 are in threaded connection with the bearing rod 3, and the suspension rods are fixed on the bearing rod 3 by using the blocking pieces 4.
