[0043] Please refer to the attached Figure 1-Figure 4 , shows a vertical lifting work platform for removing concrete from a dam working gate shaft provided in an embodiment of the present application, including: a beam frame assembly 3, a lifting assembly 4, a work platform 5 and a stabilizing assembly 6.

[0044] The working gate shaft 1 is generally opened vertically on the dam body 2. The concrete at an elevation of 92.5m to 103.5m from the bottom hole of the dam body needs to be chiseled out. The use of a vertical lifting work platform for chiseling out the concrete in the working gate shaft of the dam body will not hinder the traffic on the dam body, while being convenient for people to get on and off, and being safe and stable.

[0045] The beam assembly 3 is fixedly connected to the dam body 2 , and the beam assembly 3 spans the working gate shaft 1 . The main body of the lifting assembly 4 is installed on the beam assembly 3 . The working platform 5 is located in the working gate shaft 1 , and the working platform 5 is fixedly connected to the action end of the lifting assembly 4 .

[0046] When the lifting assembly 4 is working, the lifting assembly 4 retracts and extends its action end (the action end moves up and down), thereby driving the working platform 5 to rise and fall vertically.

[0047] The stabilizing assembly 6 is fixedly mounted on the side of the working platform 5 to improve the stability of the working platform 5 in the working door shaft 1 .

[0048] Specifically, the stabilizing assembly 6 includes: a cylinder 601 , a long rod 602 , a fastening screw 603 and a stabilizing disk 604 .

[0049] The cylinder 601 is fixedly connected to the working platform 5, the long rod 602 is located inside the cylinder 601, and a fastening screw 603 for fixing the long rod 602 and the cylinder 601 is threadedly installed on the side of the cylinder 601. After loosening the fastening screw 603, the long rod 602 can be rotated and adjusted. Both ends of the long rod 602 extend out of the cylinder 601, and the top and bottom ends of the long rod 602 are fixedly connected with a stabilizing plate 604.

[0050] like Figure 4 As shown in FIG, the stabilizing disk 604 has a large arc portion 604a and a small arc portion 604b, and two sides of the large arc portion 604a and two sides of the small arc portion 604b are fixedly connected through a first transition portion 604c and a second transition portion 604d.

[0051] When the working platform 5 is lifted vertically, the small arc portion 604 b is aligned with the outside, and there is a gap between the small arc portion 604 b and the inner wall of the working door shaft. At this time, the stabilizing assembly 6 does not hinder the vertical lifting of the working platform 5 .

[0052] When the operator is working on the working platform 5 (the working platform 5 is not raised or lowered), the large arc portion 604a is facing outward, and the large arc portion 604a can be against the inner wall of the working door shaft, making the working platform 5 more stable and ensuring the safety of the construction workers.

[0053] Among them, the design of the long rod 602 makes the working platform 5 and the stabilizing component 6 form a three-dimensional structure. When the lifting rope of one of the lifting components 4 breaks, the three-dimensional structure formed by the long rod 602 and the working platform 5 will get stuck in the working shaft, thus ensuring the safety of construction workers.

[0054] In one embodiment, the beam frame assembly 3 includes: a steel plate 301, an anchor nail 302, and an I-beam 303.

[0055] Specifically, the anchor nail 302 is an M20 expansion bolt, the steel plate 301 is a 10-mm-thick steel plate, and the I-beam 303 uses an I20 I-beam.

[0056] The steel plate 301 is fixedly connected to the dam body 2 through the anchor nail 302, and the I-beam 303 is fixedly welded to the steel plate 301.

[0057] In one embodiment, the lifting component 4 includes: an electric hoist 401 and a bifurcated lifting rope 402.

[0058] The electric hoist 401 is fixedly or slidably connected to the I-beam 303. The electric hoist 401 can be a 2t electric hoist. The moving end (hook, an anti-detachment hook can be used) of the electric hoist 401 is connected to the bifurcated lifting rope 402, and both ends of the bifurcated lifting rope 402 are connected to the lifting lugs 501 on the working platform 5.

[0059] When the electric hoist 401 works, it winds or releases the hanging rope, making the hook of the electric hoist 401 lift and lower vertically, thereby driving the bifurcated lifting rope 402 and the working platform 5 to lift and lower.

[0060] In one embodiment, the working platform 5 includes: a channel steel frame and a catwalk plate.

[0061] The channel steel frame is welded by an outer frame 502 and a reinforcing frame 503. The outer frame 502 and the reinforcing frame 503 form a "field" - shaped structure. Both the outer frame 502 and the reinforcing frame 503 are welded by 10# channel steel. The catwalk plate (not shown in the drawings) is fixedly laid full on the top of the channel steel frame. The catwalk plate is mounted on the channel steel frame and is used to support people or goods.

[0062] The catwalk plate uses a 32 - 5 cm thick catwalk plate.

[0063] In one embodiment, the central angle A corresponding to the large arc portion 604a ∈ (90, 180], and the central angle B corresponding to the small arc portion 604b ∈ (90, 180].

[0064] The central angles corresponding to the large arc portion 604a and the small arc portion 604b are both greater than 90°, such as 160°, 140°, etc.
