Abstract
Description
Technical Field
[0001] This utility model belongs to the field of auxiliary valve opening technology. Specifically, it relates to a detachable electric auxiliary handwheel opening device. Background Technology
[0002] A valve handwheel mechanism is a device used to control the opening and closing of valves. It typically consists of a handwheel, shaft, key, limit device, etc. Many valves in power plants are equipped with handwheel mechanisms, which are used to open or close the valves by turning the handwheel.
[0003] However, manually opening the valve handwheel is time-consuming and laborious. For some handwheels that require high torque, pipe wrenches may need to be prepared in advance. Some valve handwheels require a large number of turns and a large torque, which consumes a lot of the operator's physical strength, making it difficult to open and close the valve. Therefore, we have proposed a detachable electric auxiliary handwheel opening device. Utility Model Content

[0025] Example:
[0026] See attached Figures 1-5 The detachable electric auxiliary handwheel opening device provided in this embodiment includes a drive control unit 6, a torque transmission unit, and a detachable action unit 2. The torque transmission unit reduces the rotational speed and increases the torque of the power output from the drive control unit 6 before transmitting it to the detachable action unit, which then acts on the handwheel. This essentially covers various handwheel valves that are difficult to open or close, reducing the workload of operators. Specifically, the torque transmission unit includes a mounting bracket 1 and a torque conversion assembly. The mounting bracket 1 is a cylindrical structure with an opening on one side. A through-hole rotating groove 201 is provided at the center of its bottom surface. A rotating rod 202 is connected to the rotating groove 201 via a bearing structure. The rotating rod 202 can rotate relative to the rotating groove 201. The two ends of the rotating rod 202 are located on opposite sides of the mounting bracket 1, with one end connected to the detachable action unit 2 and the other end connected to the drive control unit 6 via the torque conversion assembly.
[0027] The detachable operating unit 2 includes a rotating disk 204. Several limiting rods 205, evenly distributed in a ring, are fixedly connected to one side of the rotating disk 204 for insertion into the gap of the handwheel. A through hole is provided at the center of the rotating disk 204. The end of the rotating rod 202 is configured with an external thread structure, and a stop block is fixed near the external thread structure. The rotating disk 204 is inserted by aligning the through hole with the rotating rod 202 and placing it in contact with the stop block. Then, a nut is tightened through the engagement of the nut and the external thread structure to secure the rotating disk 204. When the rotating disk 204 needs to be replaced, it can be easily disassembled and replaced via the threaded structure.
[0028] The torque conversion assembly includes a gear 203 and a retaining ring 3. The gear 203 is fixedly connected to the end of the rotating rod 202 away from the rotating disk 204. The retaining ring 3 is fixedly and parallelly connected to one side of the mounting bracket 1. The gear 203 is located inside the retaining ring 3. A gear ring 4 is provided inside the retaining ring 3. The gear ring 4 is distributed on the outside of the gear 203 and has the same center. A transmission assembly 5 is provided on the side of the fixed ring 3 away from the mounting bracket 1. This assembly transmits the power output from the drive control unit 6 to the gear 203. It includes a second mounting bracket 501, which is fixedly and parallelly connected to the other side of the fixed ring 3. That is, the first mounting bracket 1 and the second mounting bracket 501 are respectively connected to both sides of the fixed ring 3. The second mounting bracket 501 has the same cylindrical structure as the first mounting bracket 1, with a through rotating groove 502 at the center of its bottom surface. A rotating shaft 503 is connected inside the rotating groove 502 via a bearing structure. The rotating shaft 503 can rotate relative to the rotating groove 502. A rotating disk 504 is provided at one end of the rotating shaft 503 near the fixed ring 3, and the other end is connected to the drive... The drive control unit 6 has a gear assembly on the rotating disk 204 for power transmission with the gear 1 203. The gear assembly includes several connecting plates 505, preferably three connecting plates 505, which are evenly distributed around the rotating disk 204, i.e., arranged at 120-degree intervals. A rotating rod 206 is vertically provided on the connecting plate 505, and part of it extends outside the connecting plate 505. A gear 207 is connected to the rotating rod 206 through a bearing structure. The gear 207 can rotate relative to the rotating rod 206. The gear 207 is located between the gear ring 4 and the gear 1 203. The outer side of the gear 207 meshes with the inner side of the gear ring 4 and also meshes with the outer side of the gear 1 203.
[0029] The drive control unit 6 includes a mounting bracket 3 601 and a drive device, which is a motor 603. The mounting bracket 3 601 has a fixed bracket 602 inside, and the motor 603 is fixed on the fixed bracket 602. The mounting bracket 1, the fixing ring 3, the mounting bracket 2 501 and the mounting bracket 3 601 are fixedly connected in sequence. The output end of the motor 603 is fixedly connected to the rotating shaft 503. The fixed connection between the mounting bracket 2 501 and the mounting bracket 3 601 does not interfere with the relative rotation of the rotating shaft 503.
[0030] The drive control unit 6 also includes a control panel 8, which is fixedly connected to the lower side of the mounting bracket 601 and electrically connected to the motor 603. This control panel is used to control the start / stop and speed of the motor 603. Handles 7 are symmetrically provided on both sides of the mounting bracket 601 for easy operation by staff.
[0031] The working principle of this utility model is as follows: The control panel 8 controls the operation of the motor 603, and its power drives the rotating shaft 503 to rotate through the output end. The bearing structure set on the rotating groove 502 on the mounting bracket 501 supports the rotating shaft 503. The rotating shaft 503 drives the rotating disk 504 to rotate. The connecting plate 505 on the rotating disk 504 drives the three gears 507 to revolve. The gear ring 4 meshing on the outer side of the gears 507 is in a fixed state. The revolution of the gears 507 will drive the rotation of the gears 507 themselves. The rotation of the gears 507 further drives the rotation of the gear 203, thereby transmitting power to the rotating rod 202. The rotation speed of the rotating rod 202 is lower than the rotation speed of the rotating shaft 503. The three gears 507 drive the rotation of the gear 203, which increases the torque and achieves the effect of reducing the speed and increasing the torque. The limit rod 205 on the rotating disc 204 is inserted into the various gaps of the handwheel. The rotation of the limit rod 205 drives the rotation of the handwheel. This is suitable for opening and closing most handwheel valves, saving the physical strength of the staff.

Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
