[0040] Figure 1 and Figure 2 Fig. shows the nuclear power plant clamp 10 in some embodiments of the present utility model. The nuclear power plant clamp 10 is used to clamp foreign objects, etc. on the nuclear power plant, and of course, it can also be used to clamp parts, etc.

[0041] The nuclear power plant clamp 10 includes a pan-tilt device 1 and a clamp device 2, and the pan-tilt device 1 is connected to the clamp device 2. It can be understood that the pan-tilt device 1 is used to drive the clamp device 2 to rotate, and the clamp device 2 is used to complete clamping and releasing during the movement process.

[0042] As Figures 1 to 3 shown, the pan-tilt device 1 includes a pan-tilt housing 11, a slewing drive assembly 12, a pan-tilt end cover 13 and a pan-tilt output member 14. The slewing drive assembly 12 is disposed inside the pan-tilt housing 11, the pan-tilt end cover 13 is disposed on the pan-tilt housing 11, the pan-tilt output member 14 is rotatably disposed on the pan-tilt end cover 13, and the slewing drive assembly 12 is drivingly connected to the pan-tilt output member 14.

[0043] Understandably, the pan-tilt housing 11 functions to mount and protect the remaining components. The slewing drive assembly 12 is used to output torque to the pan-tilt output member 14. The pan-tilt end cap 13 is used to support the rotation of the pan-tilt output member 14. The pan-tilt output member 14 is used to drive the clamping device 2 to rotate together.

[0044] As Figures 1 to 5 shown, the clamping device 2 includes a clamping housing 21, a clamping motor 22, a clamp seat 23, a worm 24, at least two clamping jaws 25 and at least two worm wheels 26. The clamping housing 21 is fixedly connected to the pan-tilt output member 14. The clamping motor 22 and the clamp seat 23 are both arranged on the clamping housing 21. The clamping motor 22 is drivingly connected to the worm 24. The worm 24 is rotatably arranged on the clamp seat 23. Each clamping jaw 25 is respectively rotatably arranged on the clamp seat 23. Each worm wheel 26 is correspondingly arranged on each clamping jaw 25. Each worm wheel 26 is meshed with the worm 24.

[0045] Understandably, the clamping housing 21 is used to provide an installation space and installation positions for the remaining components. The clamping motor 22 is used to output torque to the worm 24. The clamp seat 23 is used to support the rotation of the worm 24. The worm 24 is used to drive each worm wheel 26 meshed with it to rotate during rotation. The worm wheel 26 is used to drive the clamping jaws 25 to rotate together during rotation. All the clamping jaws 25 are jointly used to complete the clamping of an object during rotation, etc.

[0046] It should be noted that the number of the worm wheels 26 is configured to be equal to the number of the clamping jaws 25. One worm wheel 26 is arranged on each clamping jaw 25. The rotation axis around which the worm wheel 26 rotates coincides with the rotation axis around which the clamping jaw 25 rotates. In this way, it can be ensured that the worm wheel 26 arranged on the clamping jaw 25 is always meshed with the worm 24, and the worm wheel 26 will not be driven by the rotation of the clamping jaw 25 to disengage from the worm 24. Thus, it can be ensured that the torque can always be stably and reliably transmitted, and the movement of the clamping jaw 25 can always be controlled, ensuring the control accuracy of clamping and releasing and the stable transmission of the clamping force.

[0047] Please refer to Figures 1 to 3 and, for reference together Figure 6 and Figure 7 The slewing drive assembly 12 drives the pan-tilt output member 14 to rotate relative to the pan-tilt end cap 13, and the pan-tilt output member 14 drives the clamping device 2 to slewing. As Figures 1 to 5 shown, the clamping motor 22 drives the worm 24 to rotate, so that the worm 24 drives each worm wheel 26 to rotate, and then each clamping jaw 25 rotates on the clamp seat 23 to close and clamp or open and release.

[0048] Understandably, the clamp motor 22 can be configured to use a servo motor, which has high-precision positioning ability and good torque output characteristics. Of course, the clamp motor 22 can also be configured as other types of motors in the prior art, which specifically vary depending on design and application requirements, etc.

[0049] When the clamp motor 22 is started, it drives the worm 24 to rotate, so that the worm 24 drives each worm gear 26 to rotate. Furthermore, each jaw 25 rotates on the jaw base 23 to close and clamp or open and release. The transmission ratio between the worm 24 and the worm gears 26 can be flexibly set, specifically depending on the operation precision requirements, to ensure that when the worm 24 rotates, it can drive each worm gear 26 to rotate smoothly and precisely, and further enable each jaw 25 to move synchronously.

[0050] It should be noted that the rotary drive assembly 12 can be configured to include only one motor, or can be configured to include a motor and corresponding gear reduction mechanisms, etc. Among them, the gear reduction mechanism can play a role in reducing speed and increasing torque, and can improve the rotary precision of the product.

[0051] As Figures 2 to 5 shown, in some embodiments of the nuclear power plant clamp 10, the nuclear power plant clamp 10 further includes a monitoring device 3. The monitoring device 3 includes a monitoring circuit board 31, a camera base 32, and a camera 33. Both the monitoring circuit board 31 and the camera base 32 are arranged on the jaw base 23. The camera base 32 is exposed on the surface of the jaw base 23 facing the jaws 25, and the camera 33 is located inside the camera base 32. The camera 33 is electrically connected to the monitoring circuit board 31.

[0052] Understandably, the monitoring circuit board 31 is installed on the jaw base 23, and is used to process the video signals collected by the camera 33 and send the signals to a remote operator or a control system to realize real-time monitoring of the working state of the clamp. The camera base 32 is also installed on the jaw base 23 and is exposed on the surface of the jaw base 23 facing the jaws 25, and is used to fix the camera 33 to ensure that the camera 33 can clearly capture the working area of the clamp. The camera 33 is installed inside the camera base 32 and is electrically connected to the monitoring circuit board 31 through wires, and is used to capture images when the clamp is working to ensure that the operator can observe the working conditions of the clamp in real time.

[0053] It should be noted that when the nuclear power plant clamp 10 is working, the video signals captured by the camera 33 are transmitted to the monitoring circuit board 31 through wires. The monitoring circuit board 31 processes these signals and transmits the video to a remote operator or a control system wirelessly or wiredly, so that the operator can monitor the working state of the clamp in real time to ensure the accuracy of the operation.

[0054] As Figures 2 to 5As shown, in some embodiments of the nuclear power plant clamp 10, the nuclear power plant clamp 10 further includes a lighting device 4. The lighting device 4 includes a lighting circuit board 41, a lamp holder 42, and a plurality of lamp beads 43.

[0055] Both the lighting circuit board 41 and the lamp holder 42 are disposed on the clamp base 23. The lamp holder 42 is exposed on the surface of the clamp base 23 facing the clamp jaw 25. Each lamp bead 43 is disposed on the lighting circuit board 41, and each lamp bead 43 is located within the lamp holder 42.

[0056] It can be understood that the lighting circuit board 41 is mounted on the clamp base 23 to control the on / off of the lamp beads 43 and supply power to them. The lamp holder 42 is also mounted on the clamp base 23 and is exposed on the surface of the clamp base 23 facing the clamp jaw 25 to fix the lamp beads 43 and ensure that the lamp beads 43 can effectively illuminate the working area of the clamp jaw 25. The plurality of lamp beads 43 are evenly distributed on the lighting circuit board 41 and are located inside the lamp holder 42 to ensure that the light is concentrated on the required area.

[0057] It should be noted that during use, when the nuclear power plant clamp 10 is in a working state in a low-light environment, the lighting circuit board 41 supplies power to the lamp beads 43 to make the lamp beads 43 emit light. The light emitted by the lamp beads 43 is concentrated on the clamp jaw 25 and its surrounding working area after being guided by the lamp holder 42, thereby improving the visibility and safety of the operation.

[0058] As Figure 4 shown, in some embodiments of the nuclear power plant clamp 10, the monitoring device 3 includes a monitoring sealing ring 34. The monitoring sealing ring 34 is sleeved on the camera base 32, and the monitoring sealing ring 34 abuts against the clamp base 23.

[0059] It can be understood that the monitoring sealing ring 34 is used to improve the waterproof performance of the monitoring device 3 and ensure normal operation in a harsh environment. The monitoring sealing ring 34 is installed between the camera base 32 and the clamp base 23 to ensure that the monitoring device 3 can withstand a certain water pressure, prevent water from entering the inside of the camera base 32, and protect the camera 33 and related components from damage.

[0060] During use, the monitoring sealing ring 34 forms a good sealing effect through its own elasticity and close contact. Even in a humid or water-rich environment, the monitoring sealing ring 34 can ensure that the camera 33 is not eroded by water and ensure that the monitoring device 3 can work continuously and stably.

[0061] As Figure 4 shown, the lighting device 4 further includes a lighting sealing ring 44. The lighting sealing ring 44 is sleeved on the lamp holder 42, and the lighting sealing ring 44 abuts against the lamp holder 42 and the clamp base 23 respectively.

[0062] Understandably, the lighting sealing ring 44 is used to improve the waterproof performance of the lighting device 4, ensuring normal operation even in harsh environments. The lighting sealing ring 44 is installed between the lamp holder 42 and the clamp seat 23, ensuring that the lighting device 4 can withstand a certain water pressure, preventing moisture from entering the interior of the lamp holder 42 and protecting the lamp beads 43 from damage.

[0063] As Figures 1 to 5 shown, in some embodiments of the nuclear power unit clamp 10, the clamp device 2 includes two swing arms 27, two arm pins 28, two worm wheels 26 and two clamping jaws 25. Each arm pin 28 is arranged on the clamp seat 23. The two swing arms 27 are rotatably arranged on the two arm pins 28 in a one-to-one correspondence. The two arm pins 28 penetrate through the two worm wheels 26 in a one-to-one correspondence. The two worm wheels 26 are arranged on the two swing arms 27 in a one-to-one correspondence. The two clamping jaws 25 are arranged on the two swing arms 27 in a one-to-one correspondence. Each worm wheel 26 is driven by the worm 24 to drive the swing arm 27 to rotate, so that the two swing arms 27 drive the two clamping jaws 25 to rotate on the clamp seat 23.

[0064] Understandably, the swing arm 27 is used to connect the clamping jaw 25 and the worm wheel 26, enabling the clamping jaw 25 to move as the worm wheel 26 rotates. The arm pin 28 is used to fix the swing arm 27 so that it can rotate on the clamp seat 23. The worm wheel 26 meshes with the worm 24. When the worm 24 rotates, the worm wheel 26 also rotates accordingly. The clamping jaw 25 is installed on the swing arm 27. When the swing arm 27 rotates, the clamping jaw 25 also rotates accordingly, thereby realizing the action of clamping or releasing.

[0065] It should be noted that when the worm 24 rotates driven by the clamp motor 22, the meshing worm wheel 26 also rotates accordingly. The rotation of the worm wheel 26 is transmitted to the swing arm 27 through the arm pin 28, causing the swing arm 27 to rotate. The rotation of the swing arm 27 drives the clamping jaw 25 installed thereon to rotate, thereby realizing the clamping or releasing action of the clamping jaw 25.

[0066] As Figures 1 to 4 and Figure 7 shown, in some embodiments of the nuclear power unit clamp 10, the slewing drive assembly 12 includes a slewing motor 121, a slewing drive gear 122, a slewing driven gear 123 and a slewing connection seat 124. The slewing motor 121 is arranged in the clamp housing 21. The slewing motor 121 is drivingly connected to the slewing drive gear 122. The slewing drive gear 122 meshes with the slewing driven gear 123. The slewing drive gear 122 is fixedly arranged on the slewing connection seat 124. The slewing connection seat 124 is fixedly arranged on the pan-tilt output member 14.

[0067] Understandably, the slewing motor 121 is the power source of the slewing drive assembly 12 and is used to output torque. The slewing drive gear 122 is connected to the slewing motor 121 and is used to transmit the torque of the slewing motor 121 to the slewing driven gear 123. The slewing driven gear 123 meshes with the slewing drive gear 122 and is used to receive the torque from the slewing drive gear 122. The slewing connection base 124 is used to fix the slewing drive gear 122 and connect it to the pan-tilt output member 14.

[0068] It should be noted that the slewing motor 121 is arranged inside the clamp housing 21, ensuring that the overall layout of the slewing drive assembly 12 is compact and easy to install. The slewing drive gear 122 is fixedly arranged on the slewing connection base 124, ensuring the firm installation and stable operation of the gear. The slewing connection base 124 is fixedly arranged on the pan-tilt output member 14, ensuring a reliable connection between the slewing drive assembly 12 and the pan-tilt output member 14.

[0069] When the slewing motor 121 is started, the torque output by the slewing motor 121 is transmitted to the slewing driven gear 123 through the slewing drive gear 122. The rotation of the slewing driven gear 123 is transmitted to the pan-tilt output member 14 through the slewing connection base 124, so that the pan-tilt output member 14 rotates relative to the pan-tilt end cover 13. The rotation of the pan-tilt output member 14 further drives the entire clamp device 2 to rotate, realizing the direction adjustment of the clamp device 2.

[0070] As Figure 3 and Figure 7 shown, in some embodiments of the clamp 10 of the nuclear power unit, the slewing drive assembly 12 further includes a fixing frame 125 and two slewing bearings 126. The fixing frame 125 is arranged on the pan-tilt end cover 13, and the slewing motor 121 is arranged on the fixing frame 125;

[0071] The inner rings of the two slewing bearings 126 are respectively sleeved on the pan-tilt output member 14, and the outer rings of the respective slewing bearings 126 are abutted against the pan-tilt end cover 13, and the pan-tilt output member 14 penetrates through the pan-tilt end cover 13.

[0072] Understandably, the fixing frame 125 is used to install the slewing motor 121 and fix it in place. The two slewing bearings 126 are used to support the pan-tilt output member 14 to ensure its smooth rotation relative to the pan-tilt end cover 13.

[0073] The fixing bracket 125 is arranged on the pan-tilt end cover 13, ensuring the stable installation of the slewing motor 121. The slewing motor 121 is arranged on the fixing bracket 125, ensuring the reliable connection between the motor and the slewing drive gear 122. The inner rings of the two slewing bearings 126 are respectively sleeved on the pan-tilt output member 14, ensuring the stable support of the pan-tilt output member 14. The outer rings of the respective slewing bearings 126 are all abutted against the pan-tilt end cover 13, ensuring the fixing of the slewing bearings 126 and the smooth rotation between the pan-tilt output member 14 and the pan-tilt end cover 13. The pan-tilt output member 14 penetrates through the pan-tilt end cover 13, ensuring that the pan-tilt output member 14 can rotate freely relative to the pan-tilt end cover 13.

[0074] As Figure 6 and Figure 7 shown, in some embodiments of the nuclear power unit clamp 10, the clamp device 2 further includes a cable slip ring 29. The cable slip ring 29 is located on the pan-tilt output member 14. A wire connection avoidance hole 231 is formed on the pan-tilt output member 14. The wire connection avoidance hole 231 penetrates along the length direction of the pan-tilt output member 14. The cable slip ring 29 is electrically connected to the clamp motor 22.

[0075] It can be understood that the cable slip ring 29 is installed on the pan-tilt output member 14 to provide stable power supply for the clamp motor 22 when the pan-tilt output member 14 rotates. A wire connection avoidance hole 231 is formed on the pan-tilt output member 14. The wire connection avoidance hole 231 penetrates along the length direction of the pan-tilt output member 14 to provide a channel for the wires of the cable slip ring 29.

[0076] The cable slip ring 29 is located on the pan-tilt output member 14, ensuring that the wires can move freely as the pan-tilt output member 14 rotates. The setting of the wire connection avoidance hole 231 enables the wires to pass through the pan-tilt output member 14 without obstruction, thus ensuring the smoothness of the wires when the pan-tilt output member 14 rotates.

[0077] As Figure 2 、 Figure 3 and Figure 5 shown, in some embodiments of the nuclear power unit clamp 10, a plurality of avoidance holes 231 are formed on the clamp base 23. Each clamping jaw 25 is rotatably arranged in each avoidance hole 231 in a one-to-one correspondence.

[0078] It can be understood that each avoidance hole 231 is used to accommodate and support the clamping jaw 25, ensuring that the clamping jaw 25 can rotate freely in the avoidance hole 231. When the worm 24 rotates driven by the clamp motor 22, the worm gear 26 rotates accordingly, driving the connected clamping jaw 25 to rotate in the avoidance hole 231.

[0079] As Figure 2 and Figure 3 shown, in some embodiments of the nuclear power unit clamp 10, the clamp base 23 is screwed to the clamp housing 21.

[0080] Understandably, the clamp base 23 and the clamp housing 21 are fixed together by means of a threaded connection. This connection method not only ensures the firmness of the connection but also facilitates disassembly and maintenance. The clamp base 23 and the clamp housing 21 are fixed together by means of a threaded connection, ensuring a stable connection between the two and also facilitating the installation and disassembly of the clamp base 23. When it is necessary to replace or maintain the components on the clamp base 23, the clamp base 23 can be easily disassembled by loosening the threaded connection, which is convenient for maintenance and replacement.

[0081] As Figure 1 and Figure 2 shown, in some embodiments of the nuclear power unit clamp 10, the pan housing 11 and the clamp housing 21 are both cylindrical, the clamp base 23 is columnar, and the central axes of the pan housing 11, the clamp housing 21, and the clamp base 23 coincide with each other in the length extension direction.

[0082] Understandably, the central axes of the pan housing 11, the clamp housing 21, and the clamp base 23 coincide with each other, ensuring the symmetry and balance of the overall structure, which is beneficial to reducing vibration and offset during the movement process.

[0083] The cylindrical design of the pan housing 11 and the clamp housing 21 enables the two to be closely combined to form a stable support structure. The columnar design of the clamp base 23 facilitates the installation of the worm 24, the worm gear 26, and other related components. The coincidence of the central axes of the three ensures the balance and symmetry of the overall structure.

[0084] Implementing the present utility model has the following beneficial effects:

[0085] The present utility model relates to a nuclear power unit clamp. By adopting an electric drive instead of a traditional pneumatic drive, it is not necessary to additionally equip a complex compressed air supply system, thereby reducing the equipment complexity and cost. By setting a rotary drive assembly and a worm-worm gear transmission structure, the dependence on the compressed air system is reduced. On the one hand, the application cost of the nuclear power unit clamp is reduced by eliminating the setting of the air supply equipment and the air supply system. On the other hand, the nuclear power unit clamp is no longer subject to the influence of air pressure fluctuations, making the operation of the clamp more stable and accurate, and improving the working precision of the nuclear power unit clamp.

[0086] Furthermore, the pan device and the clamp device can work independently, enabling the angles of each jaw and the clamping and releasing of each jaw to be controlled separately, further improving the clamping flexibility of the nuclear power unit clamp. By driving the jaws to move through the clamp motor, the worm, and the worm gear, the nuclear power unit clamp can adjust the clamping force and speed within a large range, improving the control flexibility of the nuclear power unit clamp.
