Description

Technical Field

[0001] The utility model relates to the technical field of underground engineering, in particular to an annular hanging basket for repairing the plug of a deep and large vertical shaft. Background Technique

[0002] At present, due to non-standard construction in the early stage and long operation time, most deep and large vertical shafts have problems such as plug displacement or even dropping, ash and slag blocking the drainage outlet, and local exposed and corroded reinforcing bars on the shaft wall. To ensure the normal operation of the vertical shaft, it is necessary to repair the plug of the vertical shaft. The significant feature of the repair of the plug of the vertical shaft is that the vertical shaft is deep and has a large inner diameter. Some vertical shafts are more than 100m deep. The high-altitude operation is difficult and dangerous, which requires a safe and reliable high-altitude operation platform.

[0003] For the high-altitude operation platform for repairing the plug of a deep and large vertical shaft, the most easily thought of is the scaffolding scheme. Scaffolding is currently commonly used in the external wall construction and decoration of buildings. The installation process is mature, and for building projects, its safety and reliability are relatively high. However, for deep and large vertical shafts, first, the depth of the vertical shaft is relatively large and the space is limited, unlike buildings where there is a relatively large space for scaffolding erection. Therefore, the scaffolding erection is difficult. Due to space limitations, the steel pipes used are short, and there are many joints in the scaffolding lap joint. More joints mean greater safety risks. Second, the erection and disassembly of the scaffolding are both time-consuming and laborious, affecting the project duration, and at the same time, the project cost is relatively high.

[0004] In addition to the scaffolding scheme, independent hanging baskets can also be used as high-altitude operation platforms for repairing the plugs of vertical shafts. The independent hanging baskets are individual hanging baskets distributed around the vertical shaft. The repair work of the plugs of the vertical shaft is carried out by lifting the hanging baskets. One hanging basket can control several plugs in one layer of the vertical shaft, and the full coverage of the plugs in one layer of the vertical shaft is achieved through multiple hanging baskets. The main problem of this scheme is that the number of hanging baskets is relatively large, and it is difficult to operate the lifting and lowering during construction, with certain safety hazards. In addition, considering the construction reasons, there is a certain change in the inner diameter of the vertical shaft from top to bottom. To ensure the normal lifting and lowering of the hanging baskets, the hanging baskets need to be at a certain distance from the shaft wall, which will lead to problems such as shaking of the hanging baskets and inability to adhere to the wall during construction. Each hanging basket works independently, and the operation progress of each hanging basket is inconsistent, which will result in the hanging baskets being at different heights. Once materials or other things accidentally fall during the construction of the operators of the high-altitude hanging baskets, it will endanger the safety of the operators of the hanging baskets below. Content of the Utility Model

[0006] The utility model provides the following technical solutions to achieve the above purpose:

[0007] A circular hanging basket for repairing the plug of a deep and large vertical shaft, comprising a vertical shaft. Eight I-beams are evenly arranged circumferentially at the top of the vertical shaft. A working steel wire rope is arranged at one end of each I-beam facing the vertical shaft. The ends of the working steel wire ropes far from the I-beams are commonly connected to the circular hanging basket. Four top wall rods are evenly arranged circumferentially on the bottom surface of the circular hanging basket.

[0008] Furthermore, a support rod is obliquely arranged at one end of each I-beam far from the vertical shaft, and the end of the support rod far from the I-beam is in close contact with the shaft wall of the vertical shaft; a reinforcing plate is arranged on the contact surface between the I-beam and the vertical shaft, and the reinforcing plate is fixed to the shaft wall of the vertical shaft by high-strength bolts.

[0009] Furthermore, an auxiliary steel wire rope is also arranged at one end of each I-beam facing the vertical shaft, and the ends of the auxiliary steel wire ropes far from the I-beams are commonly connected to the circular hanging basket.

[0010] Furthermore, three winches are evenly arranged circumferentially at the top of the vertical shaft, and each winch is connected to the circular hanging basket through a winch steel wire rope.

[0011] Furthermore, each winch is fixedly connected to the top of the vertical shaft through a safety lock. A slide rail is arranged on each winch. A pulley is arranged at one end of the slide rail facing the vertical shaft. The winch steel wire rope passes around the pulley through the slide rail and is connected to the circular hanging basket.

[0012] Furthermore, a support rod is obliquely arranged on each winch, and the end of the support rod far from the winch is in close contact with the shaft wall of the vertical shaft.
