The upper part of the two C-shaped slide rails is equipped with a ring-shaped fixing frame, and one C-shaped slide rail is connected to the ladder through a connecting piece.

The lifting frame is connected with the bottom steel beam of the lifting frame, an aluminum plywood bottom plate is installed on the bottom steel beam of the lifting frame, and a detachable protective railing is installed on the aluminum plywood bottom plate.

The operating platform is equipped with a pair of symmetrical ring-shaped fixing frames on the upper parts of the two C-shaped slide rails.

The upper part of the ladder in the operating platform has a ladder hook.

The ladder in the operating platform also includes a ladder handrail.

Compared with the prior art, the utility model has the beneficial effects that:

Compared with the prior art, the present invention solves the problem of setting up a construction operation platform in an elevator shaft:

The lifting frame is controlled by the winch to carry out the lifting operation, so as to realize the layered and full coverage of the working surface of the elevator shaft, the lifting power is sufficient, and the lifting is safe and reliable;

The lifting frame is embedded in the C-shaped slide rail, and the lower part is equipped with a limit beam, which has high safety;

It can be connected with the steel pipe outside the elevator door through the ring fixing frame, making full use of the elevator door structure, and the connection construction is simple and easy to install;

The subsequent installation of the bottom plate and protective railings of the construction platform is easy to complete and easy to operate;

Ladders are set up for people to go up and down the construction, and if the winch fails, they can return to the structural surface through the ladders. In a word, the utility model has simple installation process, convenient and fast construction, saves construction period, improves efficiency, is easy to disassemble and assemble, and can be recycled for multiple times.

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with specific embodiments.

Example 1:

A lifting construction operation platform for an elevator shaft, including a hand-operated lifting winch 1, two C-shaped slide rails 2, a lifting frame 10, and a construction platform,

The top beam and the bottom limit beam 11 are welded between the two C-shaped slide rails 2, the hand-operated lifting hoist 1 is fixed on the top beam, the lifting frame 10 is embedded in the tracks of the two C-shaped slide rails 2, and the lifting frame 10 The pulley is installed, and the hand-operated lifting hoist 1 bypasses the pulley 7 of the lifting frame 10 through the wire rope 9, and lifts or lowers the lifting frame 10;

The upper parts of two C-shaped slide rails 2 are symmetrically installed with 2 pairs of ring-shaped fixing frames 8. One C-shaped slide rail 2 is connected to the ladder 5 through a connecting piece 4. The connecting piece 4 can be a hinge. Use bolts to fix the climbing ladder 5 to the C-shaped slide rail. Rail 2, or a round tube welded to the C-shaped slide rail 2, and the ladder 5 is inserted into the round tube through the plug-in 7 to fix it;

There is a ladder hook 3 on the top of the ladder 5, and a ladder handrail 6 is installed on one side of the ladder 5;

The lifting frame 10 is welded to the bottom steel beam 14 of the lifting frame, and the bolt 15 is used to install three assembled light aluminum plywood bottom plates 12 on the bottom steel beam 14 of the lifting frame. The screw thread on the bottom plate 12 is connected so that the detachable protective railing 13 is fixed on the aluminum plywood bottom plate 12 .

When installing the liftable construction operation platform of the elevator shaft to the elevator doorway 17, first use two horizontal steel pipes 18 to pass through 2 pairs of annular fixing frames 8 respectively, after the horizontal steel pipes 18 are connected with the vertical steel pipes 18 by buckles, then Be fixed on the structural wall 16 on both sides of the elevator door opening 17, and then the ladder hook 3 is tightly hung on the horizontal steel pipe 18.

After the above-mentioned elevator shaft liftable construction operation platform is set up, the operation and construction can be carried out. The construction operation platform can be raised and lowered by using the elevator shaft, and two people can cooperate with the construction.

1) First, the construction workers prepare the construction tools and construction materials, use the hand-operated hoist 1 to lift the lifting frame 10 and the bottom steel beam 14 of the lifting frame, and place the construction tools and construction materials on the assembled lightweight aluminum On the plywood 12.

2), the construction workers fasten their safety belts, and one end is tied to the steel pipe 18 to ensure construction safety. Go down to the assembled lightweight aluminum plywood 12 by the ladder 5 to carry out the construction of the elevator shaft.
