Description

Technical Field

[0001] This utility model relates to a climbing ladder, specifically a climbing ladder for a surge tank used in the construction of a hydropower station, and belongs to the field of climbing ladder technology. Background Technology

[0002] Hydropower station construction involves the development of hydropower infrastructure, including dams, water diversion systems, and the installation of power generation equipment, ensuring the efficient conversion of water energy into electrical energy. Surge wells are used to regulate water pressure, maintain the stable operation of the water diversion system, and prevent water hammer effects on pipelines and equipment. Ladders serve as access routes for construction and operation maintenance, allowing workers to enter surge wells or other high-altitude work areas, ensuring convenience and safety for daily inspections and equipment maintenance.

[0003] Chinese Patent Publication CN222207743U discloses a ladder for a surge tank in a hydropower station. The ladder has two or more climbing frames. The hooks of the lower climbing frame engage with the horizontal ladder beams of the adjacent upper climbing frame. The horizontal ladder beam of the lowest climbing frame connects to the bottom of the surge tank, and the top of the highest climbing frame connects to the surge tank opening. This design allows operators to ascend and descend the surge tank via the ladder. When the surge tank construction is completed and the ladder needs to be dismantled, the climbing frame can be removed simply by detaching the hooks of each climbing frame from the horizontal ladder beams of its adjacent upper climbing frame. All climbing frames can be removed sequentially to complete the dismantling process. This dismantling process is convenient, time-efficient, and highly effective.

[0004] The aforementioned patented technical solution removes the climbing frame by detaching the hooks of each climbing frame from the horizontal ladder beams of the adjacent climbing frame above it. However, in practical applications, it has been found that while the climbing frames are connected to each other by hooks, which is convenient for disassembly, the hook connection is essentially a passive hooking method, lacking additional limiting and posing a risk of falling off.

[0005] Furthermore, in deeper surge tanks, the aforementioned technical solution requires the use of multiple ladders, which are connected only by hooks. When operators move on the ladders, the total length of the multiple ladders is quite long, which may cause swaying and affect personnel safety. Therefore, this paper proposes a ladder for surge tanks used in hydropower station construction. Utility Model Content

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0028] Please see Figures 1-6The present invention proposes the following implementation scheme: a ladder for a surge tank in hydropower station construction, comprising a ladder assembly 1, the ladder assembly 1 comprising two uprights 101, a plurality of crossbar components 102 fixed between the two uprights 101, the crossbar components 102 comprising two positioning plates 1021, a cross plate 1022 fixed between the two positioning plates 1021, the cross plate 1022 being fitted with an anti-slip sleeve 1023, and the anti-slip sleeve 1023 being fixed with evenly distributed anti-slip strips 1024.

[0029] Please refer to this carefully. Figure 2 and Figure 5 A guardrail assembly 4 is provided on the upright post 101. The guardrail assembly 4 includes a T-shaped plate 401, which is fixed to the upright post 101. A sliding plate 402 is slidably connected to the T-shaped plate 401. Evenly distributed arc-shaped plates 403 are fixed on the sliding plate 402. Multiple reinforcing plates 404 are fixed together on the multiple arc-shaped plates 403. When not in use, the sliding plate 402 can slide on the T-shaped plate 401 to remove the sliding plate 402, arc-shaped plates 403, and reinforcing plates 404 from the upright post 101.

[0030] A baffle 405 is fixed to the lower end of the T-shaped plate 401. The baffle 405 is fixed to the upright 101. A reinforcing block 406 is fixed to the bottom surface of the baffle 405. The reinforcing block 406 is fixed to the upright 101. The baffle 405 can block the slide plate 402 and prevent the slide plate 402 from leaving the limit of the T-shaped plate 401. The reinforcing block 406 can improve the strength of the baffle 405.

[0031] Please refer to this carefully. Figure 6 The ladder assembly 1 is equipped with a reinforcement mechanism 3, which includes a mounting plate 301. The mounting plate 301 is fixed to the upright 101. The mounting plate 301 is equipped with an external hexagonal concrete self-cutting screw 302. The external hexagonal concrete self-cutting screw 302 extends to the other side of the upright 101. Specifically, first, holes are drilled in the mounting plate 301 at the position corresponding to the well wall. Then, the external hexagonal concrete self-cutting screw 302 is driven into the hole to complete the fixation of the upright 101 and reduce the shaking of the upright 101.

[0032] Please refer to this carefully. Figure 3 and Figure 4 The ladder assembly 1 is provided with a connecting mechanism 2, which includes a first connecting plate 201 and a second connecting plate 202. The top surface of the first connecting plate 201 is fixed to the bottom surface of the upright 101, and the bottom surface of the second connecting plate 202 is fixed to the top surface of the upright 101. A fixing post 203 that penetrates the first connecting plate 201 is fixed on the second connecting plate 202.

[0033] The first connecting plate 201 is provided with a limiting component 204 for locking the fixed post 203. The limiting component 204 includes a fixed shell 2041, which is embedded in the first connecting plate 201. A trapezoidal block 2043 is slidably connected inside the fixed shell 2041. A limiting groove 2042 is opened on the fixed post 203. A moving rod 2044 that is slidably connected to the fixed shell 2041 is fixed on the trapezoidal block 2043. A compression spring 2045 is fixed inside the fixed shell 2041.

[0034] A pull block 2046 is fixed to one end of the movable rod 2044 that extends outside the fixed shell 2041. The pull block 2046 facilitates the pulling of the movable rod 2044. Pulling the movable rod 2044 can move the trapezoidal block 2043 out of the limiting groove 2042, thereby separating the first connecting plate 201 and the second connecting plate 202. The height of the limiting groove 2042 is 3-5mm greater than the height of the trapezoidal block 2043 to prevent the trapezoidal block 2043 from bearing the weight from the second connecting plate 202 and another set of uprights 101.

[0035] Working principle: When using the device, first fix the upper ends of the first set of uprights 101 and crossbars 102. Then, lower the second set using a lifting device. When the second connecting plate 202 and fixing column 203 at the top of the second set correspond to the positions of the first connecting plate 201 at the bottom of the first set, insert the fixing column 203 into the first connecting plate 201.

[0036] The fixed column 203 will push the trapezoidal block 2043 into the interior of the fixed shell 2041 until the fixed column 203 drives the limiting groove 2042 to the position of the trapezoidal block 2043. At this time, under the action of the spring force of the compression spring 2045, the trapezoidal block 2043 will reset and move into the interior of the limiting groove 2042. The trapezoidal block 2043 and the limiting groove 2042 can limit the fixed column 203, so that the fixed column 203 cannot be separated from the first connecting plate 201 under the limitation of the trapezoidal block 2043, thus reinforcing the upright 101 and reducing the risk of the fixed column 203 falling off.

[0037] The operator can use an electric wrench to drive the external hexagonal concrete self-cutting screw 302 into the well wall, thereby fixing the upright 101 to the well wall and effectively reducing the shaking of the upright 101 and the crossbar component 102.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
