Description

Technical Field

[0001] The utility model relates to the technical field of special tools for oil supply valves, in particular to a special tool for operating a water inlet quick gate oil supply valve. Background Art

[0002] The inlet accident rapid gate system is generally composed of a hydraulic hoist and rapid gate, a pump station, a control system, a solenoid valve group, a gravity oil tank, pipelines and accessories. Among them, the main function of the rapid gate is to ensure that the unit can quickly drop down to cut off the upstream water flow when it is operating abnormally to prevent the unit from overspeeding. It falls during the maintenance of the unit to ensure that the water in the flow pipe is emptied and provide safety measures for maintenance work. The rapid gate oil supply valve of the Geheyan Power Plant adopts a high-pressure ball valve with a nominal pressure of 31.5Mpa. When the rapid gate is raised to the working position, the gate holding oil pressure in the oil supply pipeline is about 5.5Mpa. During the maintenance period, in order to prevent human error or control system failure from causing the rapid gate to rise, the operator will close the inlet rapid gate oil supply valve completely, cut off the oil line, and ensure that the gate cannot be lifted during the maintenance period.

[0003] Existing technology:

[0004] During the maintenance period, operators will frequently operate the inlet rapid gate oil supply valve. The existing operating tools consist of a torque wrench and an extension rod, which are placed in the pump station room about 10 meters away from the inlet rapid gate oil supply valve. Operators need to take out tools from the pump station room and walk to the oil cylinder room. During this period, they need to carry two tools and must pass through a stainless steel ladder with an angle of about 40°. If the operator does not carry tools, there will be safety hazards when going down. Carrying two tools increases the safety risk of the operator.

[0005] Because the water inlet cylinder room is located in the concrete-cast interlayer below the water inlet dam surface, the space is small. Below the cylinder room is the quick emergency gate slot, and the cylinder base is erected on the concrete interlayer. Many parts of the base are metal grilles, which are in a special position. When operating the water inlet quick gate oil supply valve, the operator needs to climb to an operating platform about 1.5m high. The platform is adjacent to the high side, so the operator needs to wear a safety belt before operating. In addition, due to the small space and the high oil pressure of the water inlet quick gate oil supply pipeline, it often takes about 8 minutes to operate the water inlet quick gate oil supply valve, which is inefficient. There is also a risk of tools falling into the slot.

[0006] The existing operating tools are relatively simple, which are inconvenient to operate due to space problems, and are prone to causing injuries to operators or falling into the door slot. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a special tool for operating the water inlet quick gate oil supply valve. In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1~2 As shown, the embodiment of the utility model proposes a special tool for operating the oil supply valve of the water inlet quick gate, including a connecting rod 1, a base 2 and a rotating part 3. One end of the connecting rod 1 is fixedly connected with a connecting head 4 that matches the oil supply valve. The connecting head 4 adopts a matching square inner hole. The middle part of the connecting rod 1 is fixedly connected with a cylinder 5 and a limiting cylinder 6 at intervals. The other end of the connecting rod 1 is provided with a clamping head 7. Two circular holes 8 and a limiting hole 9 arranged in parallel are provided in the base 2. A horizontal groove 10 that is connected and allows the connecting rod 1 to pass through is provided between the circular hole 8 and the limiting hole 9. The circular hole 8 matches the cylinder 5, and the limiting hole 9 matches the limiting cylinder 6. Two supporting legs 11 are symmetrically fixedly connected to the base 2. The rotating part 3 is vertically arranged with the connecting rod 1, and a buckle 12 that matches the clamping head 7 is provided on the rotating part 3.

[0023] When it is necessary to operate the oil supply valve of the water inlet quick gate, the operator only needs to carry the rotating part 3 to the operating platform and use the long rod connecting rod 1 so that the operator does not need to climb onto the operating platform to perform high-altitude operations. First, align the connecting rod 1 with the oil supply valve, clamp the connecting head 4 of the connecting rod 1 with the oil replacement valve, and adjust the oil supply valve by rotating the cylinder 5 of the connecting rod 1 in the circular hole 8 of the base 2. After the adjustment is completed, pull the cylinder 5 of the connecting rod 1 out of the circular hole 8, move the connecting rod 1 horizontally, and after the connecting rod 1 passes through the horizontal groove 10, match the limit cylinder 6 on the connecting rod 1 with the limit hole 9 of the base 2, and place the connecting rod 1 on the base 2 for the next adjustment. The operator removes the rotating part 3 and takes it away to complete the adjustment operation.

[0024] In this embodiment, if Figure 1 , Figure 2 As shown, the cross-section of the limiting hole 9 and the clamping head 7 is a regular polygon. The common regular hexagon is selected to facilitate the selection of replacement tools during operation.

[0025] In this embodiment, if Figure 2As shown, a rubber pad 13 is fixedly connected to the bottom of the support leg 11 to reduce the friction between the support leg 11 and the platform, and to buffer the height of the connecting rod 1 and the oil supply valve when adjusting the operation.

[0026] In this embodiment, if Figure 2 As shown, the support leg 11 is provided with a bolt 14 for fixing the support leg 11. The support leg 11 is fixed to the operating platform by the bolt 14, and it is more convenient to adjust using the connecting rod 1.

[0027] In this embodiment, if Figure 1 As shown, the rotating member 3 is a rotating disk, and the buckle head 12 is arranged at the center of the rotating disk. An L-shaped rod can also be used, and the use of a rotating disk is convenient for operators to rotate the connecting rod 1.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
