Detailed Description
The invention is described in detail below with reference to the accompanying drawings, as shown in fig. 1-3: the utility model provides a prevent roof beam dog that falls convenient to installation, including roof 1, limiting plate 2 is installed to 1 lower surface both sides of roof, 2 outside surfaces of limiting plate and 1 lower surface of roof pass through set-square 3 and connect, it has a plurality of connecting holes 4 to open on the roof 1, be equipped with connecting stud 5 in the connecting hole 4, slide 6 is installed at 2 inside surface both ends of limiting plate, 1 below both sides of roof are equipped with lifter 7, guide block 8 is installed at lifter 7 both ends, 8 one end of guide block is located lifter 7, L shape stopper 9 is installed to 6 upper ends of slide, support column 10 has been placed in the slide 6.
In order to reduce the vibration force, a vibration damping pad 11 is installed at the lower end of the inner side surface of the limiting plate 2.
To reduce the friction force when the elevator block 7 moves, a plurality of pulleys 12 are attached to the lower surface of the elevator block 7.
To prevent this anti-drop bar stop from falling off, the length of the connecting stud 5 is longer than the length of the support post 10.
The utility model has the advantages that: the anti-falling beam stop blocks on two sides of the pier limit table are designed into a whole, the support column is placed in the slide way, the lifting block and the guide block are placed below the support column, the device is directly placed above the limit table through a hoisting device, then the anti-falling beam stop block can be moved to a position to be installed, the upper end of the anti-falling beam stop block is closer to the lower surface of the bridge, a bolt is conveniently connected to the bridge, after the installation is finished, the support column is taken down, the lifting block and the guide block can freely slide upwards, the weight of the bridge is not borne, only the limit table is limited, the installation is convenient, the device can support the lower part through a triangular plate, meanwhile, the lower end of a limit plate can be pulled through the lifting block, the guide block and the slide way, the protection effect is better, in addition, if a connecting stud is loosened and separated, the L-shaped limit block in the guide block and the slide way is used, the device can be prevented from falling, and potential safety hazards are reduced.
