Description

Technical Field

[0001] This utility model relates to the field of valve switching technology, specifically a multi-terrain valve switching tool. Background Technology

[0002] Currently, power plants commonly use F-type valve hooks as valve opening and closing tools. One end is a hook that can be firmly hung on the manual door switch during operation, while the other end is a long rod. Operators can control the manual door switch by controlling the long rod, and can also easily operate manual valves in confined spaces and low-altitude locations, greatly saving manpower.

[0003] The existing F-type valve hook has problems such as discontinuous operation and multiple manual action procedures in opening and closing operations, which may take longer. Especially when it is necessary to operate valves in the well and valves on the pipe rack, due to space constraints, manual door operation in mid-air requires climbing and scaffolding, which affects the efficiency of operation. It is relatively cumbersome, increases the labor intensity and difficulty of operation for workers, and affects the safety and efficiency of operation. Utility Model Content

Especially when it is necessary to operate valves in the well and valves on the pipe rack, due to space constraints, manual door operation in mid-air requires climbing and scaffolding, which affects the efficiency of operation, is relatively cumbersome, increases the labor intensity and difficulty of operation for workers, and affects the safety and work efficiency of operation.

[0005] This application provides a multi-terrain valve switching tool, including a lower crossbar. An upper crossbar is slidably connected to the inner wall of the lower crossbar. A single pulley is rotatably mounted on the lower end of the lower crossbar and the upper crossbar, and a double pulley is rotatably mounted on the lower end of the upper crossbar located at the junction of the lower crossbar and the upper crossbar.

The gripping mechanism then grasps the rotating end of the valve, and the operator drives one of the single pulleys to rotate via a drive mechanism. This single pulley, in conjunction with a belt, drives the double pulleys and another set of single pulleys to rotate, thus enabling the gripping mechanism to easily rotate the valve's rotating end and complete the valve's opening and closing operation. This solution offers advantages such as safety, portability, labor-saving, high efficiency, and adjustability, effectively avoiding various risks associated with confined spaces and working at heights during operation.

[0015] Optionally, a drive bevel gear is rotatably mounted on the side wall of the lower crossbar, and the drive bevel gear meshes with the driven bevel gear.

[0016] By adopting the above technical solution, the lower crossbar can provide rotational support for the active bevel gear, and when the active bevel gear rotates, it can drive the driven bevel gear to rotate, and when the driven bevel gear rotates, it can drive the single pulley to rotate.

[0017] Optionally, a manual handle is fixedly connected to the outer wall of the active bevel gear on the side away from the lower crossbar, and the manual handle is close to the periphery of the active bevel gear.

[0018] By adopting the above technical solution, the active bevel gear can fix the manual handle, while the manual handle allows the operator to easily drive the active bevel gear to rotate.

[0020] By adopting the above technical solution, the lower crossbar can fix the handle, and the handle makes it convenient for workers to pick up the device.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application facilitates the device's insertion into confined spaces by setting up upper and lower crossbars. The gripping mechanism then grasps the rotating end of the valve, and the operator drives one of the single pulleys to rotate via a drive mechanism. This single pulley, in conjunction with a belt, drives the double pulleys and another set of single pulleys to rotate, thus enabling the gripping mechanism to easily rotate the valve's rotating end and complete the valve opening and closing operation. It has the advantages of safety, portability, labor saving, high efficiency, and adjustability, effectively avoiding various risks caused by confined spaces and working at heights during operation.

[0030] The drive mechanism includes a driven bevel gear 6, which is fixedly mounted on the outer wall of one of the single pulleys 3 shafts and located below the lower crossbar 1. A driving bevel gear 7 is rotatably mounted on the side wall of the lower crossbar 1 and meshes with the driven bevel gear 6. A manual handle 8 is fixedly connected to the outer wall of the driving bevel gear 7 on the side away from the lower crossbar 1 and is close to the periphery of the driving bevel gear 7.

[0031] In the technical solution of this utility model, the upper crossbar 2 and the lower crossbar 1 facilitate the device to extend into narrow spaces, and then the gripping mechanism 5 grips the rotating end of the valve. Then, the operator drives one of the single pulleys 3 to rotate through the drive mechanism. The single pulley 3, in conjunction with the belt 9, drives the double pulleys 4 and another set of single pulleys 3 to rotate, which makes it easy for the gripping mechanism 5 to drive the rotating end of the valve to rotate, thus completing the opening and closing operation of the valve. It has the advantages of safety, portability, labor saving, high efficiency and adjustability, and effectively avoids various risks caused by limited space and working at height during operation.

[0032] In addition, the single pulley 3 can fix the driven bevel gear 6, and the lower crossbar 1 can provide rotational support for the driving bevel gear 7. When the driving bevel gear 7 rotates, it can drive the driven bevel gear 6 to rotate, and when the driven bevel gear 6 rotates, it can drive the single pulley 3 to rotate. The driving bevel gear 7 can fix the manual handle 8, and the manual handle 8 can facilitate the operator to drive the driving bevel gear 7 to rotate.

[0033] In the technical solution of this utility model, such as Figure 1 and Figure 4 As shown, a handle 10 is fixedly connected to the side of the lower crossbar 1 away from the upper crossbar 2.

The upper crossbar 2 and the lower crossbar 1 are fixedly installed by fixing bolts 11, which can connect and fix the upper crossbar 2 and the lower crossbar 1.

[0034] In the technical solution of this utility model, such as Figure 1 and Figure 3As shown, the gripping mechanism 5 includes a flange 501, which is fixedly connected to the shaft of a single pulley 3. The single pulley 3 can fix the flange 501, and when the single pulley 3 rotates, it can drive the flange 501 to rotate. Multiple sets of connecting rods 502 are welded to the circumferential surface of the flange 501. Processing groove blocks 503 are fixedly connected to the side of the multiple sets of connecting rods 502 away from the flange 501. The flange 501 can fix the connecting rods 502, and the connecting rods 502 can connect and fix the flange 501 and the processing groove blocks 503. Then, the processing groove blocks 503 can clamp the rotating end of the valve.

[0035] In use, the upper crossbar 2 and lower crossbar 1 are first connected and fixed by the fixing bolts 11. The lower crossbar 1 then fixes the handle 10, which allows the operator to easily pick up the device. The upper and lower crossbars 2 and 1 facilitate the device's insertion into confined spaces. The single pulley 3 then fixes the flange 501, and its rotation causes the flange 501 to rotate. The flange 501 then fixes the connecting rod 502, which in turn connects the flange 501 to the machining groove block 503. The fixed function, and the processing groove block 503 can then act as a locking mechanism for the rotating end of the valve, allowing the operator to manually rotate the driving bevel gear 7.
