Description

Technical Field

[0001] This utility model relates to the technical field of climbing formwork for pressure regulating well construction, specifically a detachable climbing formwork for safety protection during construction of the inner wall of a pressure regulating well. Background Technology

[0002] A surge tank, also known as a pressure well, is a mechanical device used in hydropower stations and other locations to regulate water pressure.

[0003] If the total length of the water diversion channel of a run-of-river hydropower station is relatively long, a surge chamber is often required at the junction of the tunnel and the pressure pipeline. The surge chamber can be a well-like structure excavated from the mountain, called a surge well, or a tower that rises above the ground, called a surge tower, or some kind of hybrid structure.

[0004] Because the power plant's water intake pipes are long, when the unit suddenly sheds its load and closes the guide vanes during operation, there is a significant water hammer effect due to the inertia of the water flow, which can easily damage the power generation equipment. If there is no surge tank, the water hammer will destroy the guide vanes and other flow components.

[0005] The function of a surge tank is to provide a channel for water hammer to be released, thereby reducing the pressure on the flow components.

[0006] In related technologies, for construction and maintenance, surge tanks are usually equipped with U-shaped climbing frames or fixed integrated climbing frames on the inner wall of the surge tank. Although the climbing frames mentioned above can be used for construction and maintenance inside the surge tank, the climbing frames are relatively fixed and do not have a good disassembly structure, which makes it inconvenient to disassemble them later. In addition, the climbing frames must be installed inside each surge tank, making them unusable and costly.

[0007] In view of this, this technical solution proposes a detachable climbing frame for safety protection during construction of the inner wall of a pressure regulating well, which can better solve the problems mentioned above. Utility Model Content

[0008] The technical solution adopted by this utility model is as follows: a detachable climbing frame for safety protection during construction of the inner wall of a pressure regulating well, comprising a climbing frame structure composed of climbing frame one, climbing frame two, and climbing frame three. Support rods for the inner wall of the pressure regulating well are fixed on both rear sides of climbing frame one, climbing frame two, and climbing frame three, and are used to support the climbing frame one, climbing frame two, and climbing frame three in close contact with the inner wall of the pressure regulating well. Safety belt self-locking hook protective locking frames are fixed on the inner foot pedals of climbing frame one, climbing frame two, and climbing frame three, and are used in conjunction with the self-locking hooks of the safety belts worn by the construction worker.

[0009] The top of the left support rods of both climbing frame 2 and climbing frame 3 are fixed with positioning guide posts. The positioning guide post fixed at the top of the left support rod of climbing frame 3 is inserted into the lower inside of the left support rod of climbing frame 2. The positioning guide post fixed at the top of the left support rod of climbing frame 2 is inserted into the lower inside of the left support rod of climbing frame 1. A rotating post is rotatably installed above the right support rods of climbing frame 2 and climbing frame 3, and the top of the rotating post is fixed with a threaded rod that is threadedly connected to the lower inside of the right support rods of climbing frame 1 and climbing frame 2.

[0010] The climbing frame has fixed blocks at the top of the support rods on both sides, and the fixed blocks have adjustment slots inside. A pressure regulating well opening overlap plate is inserted into the adjustment slot for use above the pressure regulating well. A pressure regulating well opening limiting plate is fixed behind the pressure regulating well opening overlap plate for use against the outer side of the pressure regulating well. A fastening bolt is threaded to the upper part of the fixed block, and the fastening bolt abuts against the top of the pressure regulating well opening overlap plate to position the pressure regulating well opening overlap plate.

[0011] In a preferred embodiment, each of the climbing frame one, climbing frame two, and climbing frame three is composed of two support rods and a foot pedal, with the foot pedal fixed between the two support rods, and there are several climbing frames two.

[0012] In a preferred embodiment, the inner wall support rod of the surge tank is adapted to the inner wall support surface of the surge tank.

[0013] In a preferred embodiment, the safety belt self-locking hook protective locking frame has a U-shaped structure and is adapted to the safety belt self-locking hook on the worker's body.

[0014] In a preferred embodiment, both the first and second climbing frames have a positioning groove on the lower part of the left side support that is adapted to the positioning guide post, and the positioning guide post is inserted into the positioning groove. The positioning guide post can be a regular hexagonal structure.

[0015] In a preferred embodiment, both the first and second climbing frames have a positioning groove on the lower part of the left side support that is adapted to the positioning guide post, and the positioning guide post is inserted into the positioning groove. The positioning guide post can be a regular hexagonal structure.

[0016] In a preferred embodiment, the lower part of the right support rod of the climbing frame one and the climbing frame two is provided with a threaded hole for use with a threaded rod, and the threaded rod is threadedly connected in the threaded hole, and the length of the threaded rod is less than the length of the positioning guide post.

[0017] In a preferred embodiment, the pressure regulating wellhead limiting plate is adapted to the outer surface of the pressure regulating well, and both sides of the fastening bolt head are fixed with operating handles for rotating the fastening bolt.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: it facilitates the assembly and installation of climbing frame one, climbing frame two, and climbing frame three into the inside of the surge tank for construction and use, and climbing frame one, climbing frame two, and climbing frame three can be used in a mobile manner, reducing the cost of fixing the climbing frame inside each surge tank for independent use in the prior art.

[0019] 1. In this utility model, when assembling and using climbing frame one, climbing frame two, and climbing frame three, first select the number of climbing frames two according to the depth of the pressure regulating well, and then assemble climbing frames two between climbing frames one and climbing frames three. When assembling climbing frames one, climbing frames two, and climbing frames three, first insert the positioning guide post fixed at the top of the left support rod of climbing frame two into the inside of the left support of climbing frame one. Since the positioning guide post is longer than the threaded rod, when the threaded rod contacts the bottom of the right support rod of climbing frame one, the rotating post can be rotated to thread the threaded rod into the lower inside of the right support rod of climbing frame one. At this time, the installation of climbing frames one and climbing frames two is completed. Then, install climbing frame three in the above installation method, and the climbing frame three can be installed below climbing frame two for use.
