[0026] The following is combined with Figure 1-7 This application is described in further detail.

[0027] The present application embodiment discloses a portable electric booster device for operating medium and large valves. Figure 1 , Figure 2 , Figure 3 , Figure 4The electric power assist device for portable operation of medium and large valves includes an electric drive wrench 1, a worm gear reducer 5 and a connecting assembly. The worm gear reducer 5 includes a housing 11, a hollow sleeve 6 is rotatably arranged in the housing 11, a worm wheel 9 is coaxially fixed outside the hollow sleeve 6, a worm 8 is meshed with the worm wheel 9, and the worm 8 is connected to the output end of the electric drive wrench 1; one end of the hollow sleeve 6 is connected to a door plate adapter 7 for clamping the door plate; the connecting assembly is used to connect the output end of the electric drive wrench 1 and the worm 8. The electric drive wrench 1 provides the main driving force, and is powered by an AC power supply. The power supply uses a maintenance box near the valve. The driving torque is 2500N.M. The electric drive wrench can use the "forward" and "reverse" modes as needed. The worm gear reducer 5 plays the role of deceleration and changing the direction of force application. After receiving the driving force, the worm 8 outputs it through the worm wheel 9. The main shaft of the worm wheel 9 uses a hollow sleeve 6 structure to facilitate passing through a manual valve with a valve main shaft.

[0028] Reference Figure 1 The connection assembly includes a coupling 4 and a first connecting shaft 2. One end of the coupling 4 is connected to the first connecting shaft 2, and the other end of the coupling 4 is connected to the output end of the electric drive wrench 1. The end of the first connecting shaft 2 away from the coupling 4 is connected to the worm 8 to ensure the normal rotation of the driving force end. The coupling 4 is key-connected to the first connecting shaft 2, and the first connecting shaft 2 is key-connected to the worm 8. The cross-section of the shaft body at the end of the first connecting shaft 2 connected to the worm 8 is circular.

[0029] Reference Figure 1 The connection assembly also includes a square groove connector 3 and a second connecting shaft 15. One end of the square groove connector 3 is plugged and adapted with the output end of the electric drive wrench 1, and the other end is key-connected with the second connecting shaft 15. The end of the second connecting shaft 15 away from the square groove connector 3 is key-connected with the coupling 15. The cross section of the shaft body of the end of the second connecting shaft 15 connected to the square groove connector 3 is square. The square groove connector 3 plays a role of connection and fixing to ensure the normal transmission of the driving force.

[0030] Reference Figure 1-6 The worm gear 9 is key-connected with the hollow sleeve 6, and the hollow sleeve 6 and the main shaft of the worm gear 9 are an integral part. One end of the hollow sleeve 6 is plugged and adapted with the top of the door plate adapter 7. The cross section of the connecting end of the hollow sleeve 6 is square, and the top of the door plate adapter 7 is a cylinder, and a square groove is provided in the center of the cylinder to facilitate the connection between the connecting end of the hollow sleeve 6 and the door plate adapter 7.

[0031] Reference Figure 5 , Figure 6 , Figure 7 The bottom of the door plate adapter 7 is fixed with claws 10, and the number of claws 10 is at least 2. In this embodiment, the number of claws 10 is set to 2. The claws 10 cooperate with the door plate spokes 13 to clamp the valve door plate 12. The door plate adapter 7 has various sizes and can be adapted to valves of different sizes.

[0032] When it is necessary to operate a manual valve, first select a suitable door disc adapter 7 according to the valve size, take the above parts to the site, and then assemble and connect the parts in sequence. After the assembly is completed, insert the hollow sleeve 6 along the direction of the valve main axis 14, and clamp the claws 10 of the door disc adapter 7 with the door disc spokes 13 to prevent the risk of sliding and falling off. Finally, connect the power supply of the electric drive wrench 1, select the "forward" or "reverse" mode according to the operating requirements, and press the button of the electric drive wrench 1 to achieve the purpose of electrically "opening" or "closing" the manual valve.

[0033] The utility model has a compact structure and is easy to carry, can reduce the difficulty of valve operation, save manpower and operation time, and can flexibly replace the door plate adapter to adapt to valves of different sizes. It is a tool that can effectively improve the switching efficiency of medium and large manual valves.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
