Detailed Description
In order to facilitate understanding of the present invention, the following description is further provided with reference to the accompanying drawings.
The utility model discloses a gallows for transferring steel cofferdam, its structure is as shown in figure 1, including end longeron 1 and top longeron 2, top longeron 2 is located end longeron 1 top, and the front end of end longeron 1 and the front end of top longeron 2 pass through 3 fixed connection of preceding bracing, and the rear end of end longeron 1 and the rear end of top longeron 2 pass through 4 fixed connection of back pull rod. When the steel cofferdam is placed by using the hanging bracket, the bottom longitudinal beam 1 is fixed on the working platform, the front end of the top longitudinal beam 2 is suspended outwards relative to the working platform, and the top longitudinal beam 2 does not exceed the working platform, so that the top longitudinal beam 2 and the bottom longitudinal beam 1 are staggered on a vertical surface, as shown in fig. 1, a front inclined strut 3 and a rear pull rod 4 are obliquely connected between the bottom longitudinal beam 1 and the top longitudinal beam 2, and the included angle between the front inclined strut 3 and the bottom longitudinal beam 1 is 45 degrees, which is optimal; and the tie point of end longeron 1 and preceding bracing 3, the tie point of end longeron 1 and back pull rod 4, the tie point of top longeron 2 and preceding bracing 3, the tie point of top longeron 2 and back pull rod 4, these four tie points are the rhombus and distribute, end longeron 1 promptly, top longeron 2, preceding bracing 3 and back pull rod 4 have formed a rhombus structure, it is unsettled outside the work platform to realize that the crane forms end longeron 1 front end when assembling with work platform through this rhombus structure, the middle rear end of end longeron 2 is fixed on work platform, the whole state that all is located work platform of top longeron 2. The utility model discloses fixed connection between each part all adopts welded connection.
In order to ensure the stability of the diamond-shaped structure, as shown in fig. 1 and 3, a middle upright post 5 is arranged between a bottom longitudinal beam 1 and a top longitudinal beam 2, the upper end of the middle upright post 5 is fixedly connected with the top longitudinal beam 2, the lower end of the middle upright post 5 is fixedly connected with the bottom longitudinal beam 1, and the bottom longitudinal beam 1 and the top longitudinal beam 2 are reinforced and supported by the middle upright post 5; in order to further ensure that the rhombic structure cannot be twisted due to water flow impact, the upper end of the middle upright post 5 is fixedly connected with the joint of the front inclined strut 3 and the top longitudinal beam 2, and the lower end of the middle upright post 5 is fixedly connected with the joint of the rear pull rod 4 and the bottom longitudinal beam 1, so that two stable triangular structures are formed between the middle upright post 5 and the front inclined strut 3, between the bottom longitudinal beam 1, between the top longitudinal beam 2 and between the rear pull rod 4, and the torsion resistance of the rhombic structure can be greatly improved.
Further, in order to avoid the phenomenon that the hanger is deviated, the insole longitudinal beam 1 and the top longitudinal beam 2 of the utility model are both provided with two pieces, as shown in fig. 1 and fig. 2, the two bottom longitudinal beams 1 are arranged side by side, the two bottom longitudinal beams 2 are also arranged side by side, the two bottom longitudinal beams 1 are fixedly connected through a bottom longitudinal beam connecting rod 6, and the two top longitudinal beams 2 are fixedly connected through a top longitudinal beam connecting rod 7; certainly, the bottom longitudinal beam 1 and the top longitudinal beam 2 are two, and the front inclined strut 3, the rear pull rod 4 and the middle upright post 5 which are matched with the bottom longitudinal beam and the top longitudinal beam are also two, so that the whole hanger is of a rhombic box structure, has more excellent torsion resistance and bending resistance, and can not be deviated when being installed on a working platform.
