Contents of the invention

The purpose of this utility model is to solve the problem that it is difficult for operators to safely reach the aerial operation platform due to the complex environment and limited space during the construction of the inner cross beam of the prefabricated small box girder, and to provide a kind of structure with reasonable design, simple operation, easy to carry and install The hanging basket device used for the construction of prefabricated small box girder with small occupation space.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a hanging basket device for the construction of a prefabricated small box girder, including a platform bottom plate, which is characterized in that the two sides of the platform bottom plate are respectively hinged to a A vertical step ladder, the vertical step ladder includes two parallel straight rods, a crosspiece is arranged between the two straight rods, and a suspension ring is arranged on the top of the straight rods. The technical solution is to make two pieces of vertical steps parallel to each other when they are in the working state with steel bars commonly used in engineering, and use steel mesh sheets at the bottom of the vertical steps to form the bottom plate of the work platform, and hang the whole device through the lifting ring On the plane of the box girder or bridge, since the vertical step ladder and the platform bottom plate are hinged, the platform bottom plate and the vertical steps on both sides are folded and installed to avoid the problem of small hanging space and difficult installation, and the operation speed is fast .

As a preference, hinge rings are provided at both ends of the bottom plate of the platform, and horizontal pins passing through the hinge rings are provided at the bottom of the vertical steps. Safety is the prerequisite for this device. The hinge rings at both ends are made of steel with sufficient strength, and more than two pieces are installed on each side, and all hinge rings on one side are coaxial with the horizontal pin.

Preferably, the suspension ring is a closed ring structure. The lifting ring is the supporting part that bears all the gravity on the upper end, and the closed ring structure prevents the hanging rod from being separated from the lifting ring to ensure safety.

Preferably, the vertical step ladder is formed by connecting several middle sections. The device can be made into a multi-section assembly structure to meet the hanging requirements of different heights.

Preferably, a connecting sleeve is provided at one end of the middle section, and a set screw is provided on the connecting sleeve. Connect and install an appropriate amount of intermediate sections according to the actual height, which is easy to carry and quick to assemble.

Preferably, the other end of the middle section is provided with screw holes or hole slots for cooperating with set screws. The middle section and the fixed section are connected by plugging and screw fastening, which is safe and efficient.

The beneficial effects of the utility model are: small and light, easy to carry and easy to install, simple to manufacture, foldable between the vertical step ladder and the platform bottom plate, suitable for stretching and hanging construction at the construction site where the bridge deck position is narrow, good stability in use, and operability Strong, safe and reliable.
