DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] The utility model provides Figure 1-5 A portable valve operating device shown in the figure includes an operating shell 2, and a clamping slider 12 for clamping the valve body 1 for fixing the operating shell 2 is provided at the bottom end of the operating shell 2. The bottom end of the operating shell 2 is provided with a plurality of clamping arms 8 for driving the handwheel 10 at the top end of the valve body 1 to rotate synchronously. The clamping arms 8 are slidably arranged at the bottom end of the loosening block 7, and a transmission gear 4 for driving the loosening block 7 to rotate is provided inside the operating shell 2. By clamping the clamping slider 12, the problem of the fixing device of the portable valve operating device occupying too much space and being inconvenient to carry due to different sizes and distances between the pipeline and the valve is avoided.

[0024] The top of the loosening block 7 at the center position is connected to the valve gear 6 located inside the operating housing 2 through a gear shaft. The valve gear 6 can drive the loosening block 7 to rotate. A driven gear 5 is also provided inside the operating housing 2. The driven gear 5 is respectively engaged with the valve gear 6 and the transmission gear 4. The top of the operating housing 2 is provided with a rotating motor 3 for driving the transmission gear 4 to rotate. After the operating housing 2 is fixed, the loosening block 7 is driven to rotate by the valve gear 6, thereby achieving the effect of driving the handwheel 10 to rotate.

[0025] The bottom end of the unscrewing block 7 is provided with a plurality of sliding grooves 16 for the clamping arms 8 to slide synchronously inward or outward. The plurality of clamping arms 8 are all threadedly connected with a threaded transmission rod 17, one end of which passes through the unscrewing block 7 and extends to the outer wall of the unscrewing block 7. The threaded transmission rod 17 is provided with a bevel gear 18 for the synchronous rotation of the plurality of threaded transmission rods 17 near the center of the unscrewing block 7. The synchronous rotation of the threaded transmission rod 17 and the bevel gear 18 realizes the synchronous clamping of the hand wheel 10, so that the valve cover 11 is in the center position of the centering cavity 9 on both sides, which is convenient for the clamping sliders 12 on both sides to clamp and fix the valve cover 11 to avoid shaking and falling off during work. The end face of the threaded transmission rod 17 extending to the outside of the unscrewing block 7 is provided with a protrusion that is easy to rotate. By controlling its rotation, the synchronous rotation of the plurality of threaded transmission rods 17 is realized, thereby achieving the clamping effect.

[0026] Two long rods are provided at the bottom end of the clamping arm 8, one of which is used to clamp the outer wall of the handwheel 10, and the other is located in the empty groove inside the handwheel 10.

The damping block 13 is provided with an arc-shaped end face at one end close to the valve cover 11, and a plurality of friction patterns for increasing the friction force are provided in the end face. The bottom and top ends of the damping block 13 can be provided with a stopper for limiting the position in a manner that can fall off, thereby preventing it from falling off.

[0029] A threaded push rod 14 is provided on the outside of the centering cavity 9, one end of the threaded push rod 14 passes through the centering cavity 9 and extends to one side of the clamping slider 12. The threaded push rod 14 is threadedly connected to the centering cavity 9. The threaded push rod 14 can be rotated on one side of the clamping slider 12. The end face of the threaded push rod 14 is provided with a manual wheel 15 for controlling the rotation of the threaded push rod 14. The threaded push rod 14 is rotated to push out or retract the clamping slider 12, thereby realizing the disassembly and installation of the operating housing 2 and the valve body 1, reducing the difficulty of installation.

[0030] The utility model firstly clamps the clamping arm 8 and the handwheel 10 by setting the loosening block 7 and the clamping arm 8 through the synchronous rotation of the threaded transmission rod 17. After the clamping is completed, the clamping slider 12 clamps the valve cover 11 by rotating the manual wheels 15 on both sides, ensuring that the operating shell 2 is in a fixed state during the rotation of the loosening block 7, achieving uniform clamping force, and avoiding offset or shaking during operation. The setting of the clamping valve cover 11 can make the device applicable to pipes of different sizes and specifications. The device will not rotate with the rotation of the loosening block 7, and the handwheel 10 of the valve body 1 can be loosened or tightened. By controlling the rotation speed of the driven gear 5, the rotation speed of the loosening block 7 can be controlled, which meets the scenario where the valve needs to be rotated multiple times. The valve switch is controlled by automatic rotation. In an emergency, the rapid rotation of the device can speed up the closing speed of the valve.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
