[0039] In glass production workshops, some chemical equipment pipelines require the valves to be opened and closed by turning valve handwheels. In the current technology, most valve handwheels are still manually turned by operators. Because valve handwheels are generally large and some handwheels are installed in inconvenient locations, turning valve handwheels is extremely laborious, slow, and inefficient.
[0040] To address the aforementioned problems, this application proposes a handwheel rotation mechanism, which includes a frame 100, a drive component 200, and a chuck 300, as follows: Figures 2 to 4 As shown, the frame 100 has a plate-like structure. The drive unit 200 and the chuck 300 are located on the front and rear sides of the frame 100, respectively. Handheld brackets 400 are connected to the left and right sides of the frame 100, making it convenient for operators to hold and move the handwheel rotation mechanism. For ease of description, the side of the frame 100 facing the valve handwheel is designated as the first side, and the side of the frame 100 away from the valve handwheel is designated as the second side. The drive unit 200 is generally located on the second side, and the chuck 300 is located on the first side.
[0041] The frame 100 is further defined with a through-hole 111, which connects a first side and a second side. The drive unit 200 includes a drive section 210 and an output shaft 220. The drive section 210 is a motor, electric motor, or other power source. The output shaft 220 extends from the drive section 210, passes through the first mounting hole 111, and is connected to the chuck 300 via a flange 230. Thus, the chuck 300 can rotate relative to the frame 100 under the drive of the drive unit 200.
[0042] like Figure 1 As shown, a valve handwheel typically includes a rotating shaft 500, an annular portion 510, and multiple support rods 520. The rotating shaft 500 is used to connect to the valve core. The annular portion 510 is sleeved on the rotating shaft 500. Each support rod 520 is disposed between the annular portion 510 and the rotating shaft 500, with its two ends connected to the annular portion 510 and the rotating shaft 500, respectively. It should be noted that... Figure 1 The figures (a) and (b) show valve handwheels of different specifications, with different numbers of support rods 520.
[0043] To engage with the valve handwheel, the chuck 300 is equipped with a corresponding engagement structure. Specifically, such as... Figure 3 and Figure 4 As shown, the chuck 300 includes a second main body 310 and a plurality of engaging members 320 disposed on the second main body 310. The engaging members 320 are spaced apart circumferentially along the chuck 300, thereby defining a first gap 321 between adjacent engaging members 320. The first gap 321 is used for engaging with the support rod 520 of the valve handwheel.
[0044] Understandably, when the valve handwheel needs to be turned, the operator simply aligns the first gap 321 on the chuck 300 of the handwheel rotation mechanism with the support rod 520 of the valve handwheel, inserts it, and then activates the drive unit 200. The drive unit 210 drives the output shaft 220 to rotate, and the chuck 300 rotates accordingly. Through the abutment transmission between the locking member 320 and the support rod 520, the valve handwheel can be rotated easily and efficiently, significantly improving operational convenience and work efficiency. Furthermore, this mechanism is compact in design, easy to install and maintain, and suitable for various specifications of valve handwheels, greatly reducing the labor intensity of operators and further optimizing the production process.
[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, the handwheel rotation mechanism includes two handholds 400, which are respectively connected to both sides of the frame 100. The distance between the two handholds 400 gradually increases from the first side to the second side. The operator can hold the handholds 400 with both hands to maintain balance and apply force easily, ensuring a smooth and stable rotation process, further improving the comfort and safety of operation. In addition, because the handholds 400 have a tapered structure with a gradually increasing distance from the first side to the second side, it can reduce the operator's arm span, conforming to ergonomic design, and enhance the stability of the mechanism, effectively preventing wobbling or deviation caused by improper force during operation.
[0046] Furthermore, such as Figure 4 As shown, the frame 100 includes a first main body 110 and two side wings 120 respectively disposed on the left and right sides of the first main body 110. The first main body 110 has a first mounting hole 111 for connecting the drive component 200. The side wings 120 are used to connect the handheld bracket 400. Along the direction from the first side to the second side, the distance between the two side wings 120 gradually increases, so that after the handheld bracket 400 is connected to the side wings 120, the handheld bracket 400 naturally presents a conical layout.
[0047] In addition, such as Figure 4 As shown, the handheld holder 400 includes a first connecting rod 410, a second connecting rod 420, and a gripping rod 430. One end of the first connecting rod 410 and the second connecting rod 420 is connected to the frame 100. Along the direction away from the frame 100, the distance between the first connecting rod 410 and the second connecting rod 420 gradually increases, and they connect to the gripping rod 430 at their ends, thus enclosing and defining a triangular gripping space 440. On one hand, this hollow structure reduces the weight of the entire handwheel rotation mechanism and helps reduce the operator's load. On the other hand, the triangular structure of the first connecting rod 410, the second connecting rod 420, and the gripping rod 430 enhances grip stability and ensures even force application. The surface of the gripping rod 430 is made of a non-slip material, improving grip comfort and reducing fatigue during prolonged operation. The overall design balances lightweight and robustness, adapting to the needs of use in various complex environments.
[0048] In some embodiments, the handwheel rotation mechanism includes multiple chucks 300 of different specifications to accommodate valve handwheels of different diameters. The chucks 300 employ a modular design for easy and quick replacement, ensuring operational flexibility and versatility. It is understood that when opening and closing the valve, the size of the valve handwheel and the required chuck 300 specification are first determined, and then the appropriate chuck 300 is selected to connect to the output shaft 220 of the drive unit 200. The size of the first gap 321 of each chuck 300 is different, and / or the number of first gaps 321 of each chuck 300 is different, thus corresponding to valve handwheels of different diameters and valve handwheels with different numbers of support rods 520.
[0049] In some embodiments, the handwheel rotation mechanism is also equipped with a foot pedal controller (not shown in the figure), which is communicatively connected to the drive unit 200. It should be noted that the foot pedal controller is used to control the start / stop, forward / reverse rotation, and rotation speed of the drive unit 200, and commands are input through different pedals and pedaling forces. The foot pedal controller can transmit signals to the drive unit 200 wirelessly via Bluetooth, WiFi, radio frequency, or wired signals via cable. The foot pedal controller is detached from the drive unit 200 and can be placed on the ground, allowing the operator to hold the handheld bracket 400 of the handwheel rotation mechanism with both hands to engage with the valve handwheel, while simultaneously using their feet to flexibly control the foot pedal controller. It should be noted that the foot pedal controller is a conventional technique used by those skilled in the art, and its implementation principle will not be elaborated upon here.
[0050] In some embodiments, the connector 320 defines a connector slot 322, such as Figure 5 As shown, the locking groove 322 can be rectangular, arc-shaped, or other shapes, and is formed on both sides of the locking member 320 along the circumference of the chuck 300, communicating with the first gap 321 on the corresponding side. The size of the locking groove 322 is adapted to the diameter of the support rod 520 of the valve handwheel, and can accommodate at least part of the support rod 520. Thus, when the chuck 300 rotates clockwise or counterclockwise, the support rod 520 can be embedded in the locking groove 322 and its displacement along the axial direction of the chuck 300 is restricted by the groove wall of the locking groove 322, reducing the risk of the chuck 300 and the support rod 520 becoming detached during rotation. Through this design, the tight fit between the locking member 320 and the support rod 520 further improves the stability and safety of the handwheel rotation mechanism.
[0051] Furthermore, each snap-fit component 320 is defined with two snap-fit slots 322. The two snap-fit slots 322 are located on both sides of the snap-fit component 320 along the circumference of the chuck 300, thereby connecting the first gaps 321 on both sides of the snap-fit component 320, so that the chuck 300 can be inserted into the corresponding snap-fit slots 322 whether it rotates forward or backward.
[0052] In some embodiments, the chuck 300 includes a second body portion 310, and each latching member 320 is disposed on the second body portion 310, such as Figure 6 As shown, the second main body 310 defines multiple sets of mounting portions 311, each set of mounting portions 311 being arranged at intervals along the circumference of the second main body 310. Each set of mounting portions 311 includes multiple second mounting holes 312 arranged at intervals along the radial direction of the second main body 310, and each snap-fit member 320 is connected to the corresponding second mounting hole 312. It is understood that the snap-fit member 320 can be a cylindrical, square, or other cylindrical structure, capable of being detachably connected to the second main body 310. Thus, the snap-fit member 320 has multiple mounting positions on the second main body 310. When corresponding to valve handwheels of different specifications, only the position of the snap-fit member 320 needs to be adjusted to achieve quick adaptation, improving the versatility and flexibility of the equipment.
[0053] In some embodiments, the drive component 200 is a pneumatic motor. It should be noted that the pneumatic motor is driven by compressed air, and has the characteristics of high efficiency and stability, making it suitable for various working environments. Furthermore, the pneumatic motor does not generate electrical sparks during operation, making it suitable for flammable and explosive environments, such as underground coal mines and chemical workshops.
[0054] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
