Detailed Implementation

[0020] The following embodiments further illustrate the above-described content of the present invention in detail. Obviously, the described embodiments are merely a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Refer to Figure 1-4 The diagram below is a structural schematic of Embodiment 1 of this utility model. This embodiment discloses a safety protection and climbing platform for elevator shaft construction in building engineering, which includes a support frame 6. The support frame 6 is a triangular prism with a frame structure. Its cross-section is triangular, including two right-angled faces and one inclined face, as well as two triangular faces of the same shape. The right-angled faces are the faces where the two right-angled faces of the triangular cross-section are located, and the inclined face is the face where the hypotenuse of the triangular interface is located.

[0022] In the technical solution, one right-angled surface is the work platform 4, the inclined surface is the ladder 3, and the other right-angled surface is the access opening. Workers can enter the area of ​​the triangular prism formed by the support frame 6 through the access opening on the right-angled surface, and then climb up the ladder 3 to reach the work platform 4. The surface of the work platform 4 has access holes, and a cover plate 11 is installed on the access holes. The cover plate 11 is connected to the work platform 4 via a cover plate hinge. Workers reach the access holes via the ladder 3 and... The access hole leads to the upper surface of the work platform 4; the support frame 6 is equipped with adjustable wall-mounted wheels 1 and a support flap 7. The adjustable wall-mounted wheels 1 are located on one side of the support frame 6, and the support flap 7 is located on the other side of the support frame 6. The support flap 7 is hinged to the support frame 6. A flap support block 5 is located at one end of the support flap 7. The flap support block 5 is located inside the support frame 6. When the other end of the support flap 7 is supported at the elevator entrance, the flap support block 5 can support the support flap 7 and prevent the support flap 7 from flipping.

[0023] The other end of the supporting flap 7 is supported at the elevator entrance, which means that one end of the supporting flap 7 is supported on the flap support block 5, and the other end is supported on the floor.

[0024] As an improvement, the support frame 6 is also equipped with a wall-mounted sliding shoe 2, which is made of rubber or nylon.

[0025] The wall-mounted sliding shoe 2 is installed below the supporting flap 7 and is used to contact the wall of the elevator shaft for shock absorption and slip prevention.

[0026] As an improvement, the adjustable wall-mounted wheel 1 is located at one end of the working platform 4 of the support frame 6, that is, at the apex of the triangle, and the wall-mounted sliding shoe 2 and the support flap 7 are located at the entrance opening of the support frame 6, that is, on the other right-angled surface of the triangle.

[0027] As an improvement, the adjustable wall-mounted wheel 1 includes a wall-mounted wheel bracket 14. The support wheel is mounted on the wall-mounted wheel bracket 14 via an axle. The wall-mounted wheel bracket 14 is provided with a lead screw 17. The lead screw 17 is provided with nuts A15 and B16. The lead screw 17 passes through the support frame 6. Nuts A15 and B16 are respectively located on both sides of the support frame 6. The distance between the support wheel and the support frame 6 is adjusted by moving the lead screw 17. Then, by rotating nuts A15 and B16, the nuts A15 and B16 are brought into contact with the surface of the support frame 6 to fix the position of the lead screw 17.

[0028] In actual use, the lead screw 17 can move freely on the support frame 6. When it moves to the position that needs to be fixed, the position of the lead screw 17 is fixed by clamping the support frame 6 with nuts A15 and B16.

[0029] The length of the lead screw 17 extending out of the support frame 6 is determined by the size of the elevator shaft. The lead screw 17 extends out of the support frame 6 to fix the support frame 6 between the two floors of the elevator shaft.

[0030] As an improvement, the work platform 4 is fixed to the support frame 6 by steel platform fixing bolts 10.

[0031] As an improvement, handrails are provided on both sides of the ladder 3 for people to climb.

[0032] In actual use: Place this device in the elevator shaft, and support it on the wall opposite the elevator door opening through the adjustable wall-mounted wheel 1 on one side of the support frame 6. Support the flap 7 on the ground. At this time, the support flap 7 is supported on the ground of one of the floors, and the adjustable wall-mounted wheel 1 is on the floor above that floor. The adjustable wall-mounted wheel 1 is higher than the ground of this floor.

[0033] With the combined action of the adjustable wall-mounted wheel 1 and the supporting flap 7, this device is placed in the elevator shaft between two floors. Workers enter the elevator shaft from the building on the lower floor through the access ladder 3 and go up to the work platform 4 to carry out their work. The work platform is on a different floor from the access opening in the building.

[0034] The support frame is formed by welding channel steel. During building construction, after the lowest elevator shaft is completed, this device can be lifted into the elevator shaft from the top using a crane. The support flap 7 is rotated to lock onto the bottom platform of the lower elevator door opening. The other end of the support flap 7 is supported by the flap support block 5, which restricts its rotation. When constructing elevator shafts of different sizes, steel platforms of different sizes can be used to meet the construction needs. The level of the steel platform and the gap between the platform and the inner wall of the shaft can also be adjusted using wall-mounted wheels. If necessary, several commonly used tripods and steel platforms of different structural sizes can be custom-made to meet the construction needs of elevator shafts of different structural sizes.

[0035] Through repeated practice and continuous improvement, this device has increased worker efficiency and effectively curbed production safety accidents. The use of this climbing platform has significantly improved the indirect economic benefits of construction projects, and its prospects for promotion are broad.
