Description

Technical Field

[0001] This invention belongs to the technical field of mechanical equipment for roof-mounted installation in nuclear power plants, and specifically relates to an airborne device for roof-mounted installation in nuclear power plants. Background Technology

[0002] During the construction of a nuclear power plant, various components need to be installed on the ceilings of numerous functional rooms to facilitate unit maintenance and material transfer. These components include the I-beam rails and load-bearing beams for maintenance monorail cranes, large-diameter process pipes, ventilation ducts, cable trays, and lighting fixtures.

[0003] Taking I-beams as an example, small gantry cranes need to be installed above the unit. The gantry cranes need to lift the I-beams to the ceiling to complete the welding. However, due to the compact rooms and limited passageway width inside nuclear power plants, large hoisting equipment cannot be used. The current construction methods involve manual handling and scaffolding, followed by manual lifting. Alternatively, expansion bolts are driven into the ceiling, and a hand-operated hoist is used to hoist the I-beams into place for welding. However, this construction method is extremely time-consuming and labor-intensive. In some projects, scissor lifts can be introduced to reduce manpower input. However, for this type of work vehicle, the maximum height from the floor to the ceiling in nuclear power plant rooms is 5 meters. The internal space is relatively small, with a lot of equipment and materials and narrow passageways, making it unsuitable for overhead installation work. Summary of the Invention

The frame is also provided with climbing frames that can be raised and lowered along the height direction on both sides, and a material tray for clamping the top-mounted crane is provided on the top of the climbing frame. The lifting mechanism includes a fixed base, a lifting drive structure located within the fixed base, and a lifting column that is driven to rise and fall along the height direction by the lifting drive structure; after the lifting column is lifted to the ceiling construction height, the material pallet is driven by the drive mechanism to rise relative to the lifting column along the height direction, and the climbing frame rises synchronously with the material pallet. The drive mechanism is wound with a traction component for transmitting traction force. The top of the lifting column is provided with a matching frame. The matching frame is connected to the drive mechanism through the traction component, and one end of the traction component is fixed to the material pallet via the matching frame.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example like Figures 1-3 As shown, an airborne device for the installation of a top-mounted crane in a nuclear power plant according to an embodiment of the present invention will be described in detail. It includes at least one main body of equipment for lifting materials. In this embodiment, the equipment is mainly used to solve the related problems of the installation of top-mounted cranes (I-beams) in the construction of nuclear power plants. At the same time, each I-beam will be worked by two main bodies of the equipment working together. It includes a frame 1, a lifting mechanism 3 located in the middle of the frame 1, and a drive mechanism 4 located on the rear side of the frame 1 with a traction member 40 wound on it. The frame 1 is also provided with climbing frames 5 that can be raised and lowered along the height direction on both sides. The top of the climbing frame 5 is provided with a material tray 6 for clamping the top-mounted crane. The lifting mechanism 3 includes a fixed base 31, a lifting drive structure disposed within the fixed base 31, and a lifting column 32 that is axially aligned with the fixed base 31 and driven by the lifting drive structure to rise and fall along the height direction. Its working mode is as follows: after the lifting column 32 is lifted to the ceiling, it provides support to the main body of the equipment. Then, the drive mechanism 4 drives the material tray 6 to rise relative to the lifting column 32 along the height direction, while the climbing frame 5 rises synchronously with the material tray 6. To enable the material tray 6 to be driven upwards, a traction component 40 for transmitting traction force is wound around the drive mechanism 4. A cooperating frame 33 is provided at the top of the lifting column 32, and the cooperating frame 33 is connected by a traction component. The component 40 is connected to the drive mechanism 4, and one end of the traction component 40 is fixed to the material pallet 6 via the mating frame 33. That is to say, the jacking mechanism 3 can initially lift the mating frame 33 to a suitable working height, providing a support force in advance so that the ceiling and the ground form a rigid support. Then, the drive mechanism 4 pulls up the material pallet 6 and the I-beam it holds through the mating frame 33, and then the jacking installation operation is carried out. When two main bodies of the equipment work together, the jacking, traction and other processes of the two are carried out simultaneously. The traction component 40 can be either a wire rope or a chain. In this embodiment, a wire rope will be selected as the component that transmits traction force.

[0021] Please see Figure 6As shown, in order to better connect the transmission connection frame 33 and the traction member 40, the frame 33 includes a frame body 331 fixedly mounted on the top of the lifting column 32 and at least one idler wheel 332 rotatably mounted on the frame body 331. In this embodiment, two idler wheels 332 are specifically arranged front and rear. The traction member 40 is pulled out by the drive mechanism 4 and wound onto the two idler wheels 332 in sequence, and then fixed to the material tray 6. The idler wheels can smoothly distribute the friction and impact force at the bend of the rope, making the traction process more stable and controllable.

[0022] Please see Figure 3 , 4 As shown in Figure 5, the material pallet 6 is the core component for clamping and transporting the I-beam. It includes a positioning frame 61 and a pallet frame 62 slidably mounted on the positioning frame 61. The pallet frame 62 is equipped with a self-centering clamp 63 for clamping the top hanger. The self-centering clamp 63 is equipped with insulating strips 64 at the front and rear. In order to facilitate the adjustment of the clamping force on the I-beam, the positioning frame 61 has insertion holes 65 on both sides for adjusting the clamping force of the self-centering clamp 63. During use, the pallet frame 62 can slide up and down relative to the positioning frame 61, thereby adaptively adjusting the position between the I-beam and the embedded part, which is convenient for operators to perform welding and other work. The self-centering clamp 63 can ensure the centering stability of the clamped workpiece, which is especially suitable for symmetrical workpieces such as I-beams and improves the safety of operation. As a preferred embodiment, the insulating strip 64 will be made of 50x50cm square wood, which can both isolate the welding current and have excellent anti-slip properties.

[0023] It should be noted that the sliding connection between the positioning frame 61 and the pallet frame 62 is achieved by setting several vertical slide rails on the positioning frame 61, and setting corresponding track pulleys on the pallet frame 62.

[0024] Please see Figure 4 , 6 As shown, in order for the drive mechanism 4 to pull the material pallet 6, the pallet frame 62 is also provided with a fixing hole 66 for connecting and fixing the traction member 40. The traction member 40 is fixed to the fixing hole 66 via an idler wheel 332. The fixing hole 66 is located on the side facing the lifting column 32 to facilitate its lifting operation.

[0025] Please see Figure 4 , 5As shown, the self-centering clamp 63 specifically includes a positioning strip 631 horizontally fixed to the bottom of the pallet frame 62, two clamping blocks 632 slidably disposed on the positioning strip 631, and an adjusting screw 633 horizontally penetrating the two clamping blocks 632 and adjustable to move towards the center. Thus, the I-beam can be stably clamped by the above components. The insertion holes 65 on both sides facilitate the operator to control the adjusting screw 633. As a preferred embodiment, the self-centering clamp 63 can preferably be a self-centering vise, and the double-ended screw of the vise can be adjusted by hooking the ring on the vise with a special tool, which is convenient to operate.

[0026] As a preferred embodiment, the drive mechanism 4 is preferably a winch, which can provide strong, controllable and stable traction, and the size selection is adapted to the flexible airborne equipment of this embodiment.

[0027] Please see Figure 7 , 8 As shown, after the lifting column 32 is raised to the ceiling construction height, the climbing frame 5 rises synchronously in the height direction along with the material pallet 6 pulled up by the driven mechanism 4. Specifically, after the I-beam is clamped by the material pallet 6, the lifting mechanism 3 is first activated to control the lifting column 32 to raise the supporting frame 33 to the ceiling hoisting height. By first raising the lifting column 32 to the ceiling, a rigid support is formed between the ceiling and the ground in advance to ensure the safety of the construction operation. Then, the climbing frame 5 rises in the height direction along with the material pallet 6. The climbing frame 5 will provide stability and support for the material pallet 6 during the lifting process. It is particularly suitable for narrow scenarios with ceilings, such as nuclear power and hydropower plants, and can solve the problem that large equipment cannot enter and can only be erected manually.

[0028] As a preferred embodiment, the climbing frame 5 is preferably a folding scissor frame. Its intersecting structure makes the force distribution uniform, further improving the stability of the operation. After being folded and stored, the compact overall structure allows it to easily pass through narrow passages in nuclear power plants or complete operations in areas with limited space. During operation: after the lifting column 32 is lifted to the hoisting height, the folding scissor frame is driven by the drive mechanism 4 and pulls the material pallet 6 upward through the traction member 40 via the idler wheel 332 while extending and rising in the height direction. Conversely, it is folded and stored. The lifting drive structure is a linear drive mechanism, the output end of which is connected to the lifting column 32. It is used to drive the lifting column 32 to perform linear lifting and lowering motion relative to the fixed seat 31. The linear drive mechanism mentioned in this invention refers to any mechanical mechanism that can output linear displacement to drive the lifting column 32 to rise and fall relative to the fixed seat 31. The linear drive mechanism is any one of the following: screw lifting mechanism, hydraulic cylinder mechanism, electric push rod mechanism, and gear and rack mechanism, and includes but is not limited to the above-mentioned mechanical mechanism types. As a preferred embodiment, the linear drive mechanism in this embodiment preferably adopts a screw lifting mechanism. It should be noted that those skilled in the art should understand that screw lifting is only a preferred embodiment. The linear drive mechanism can also adopt electric push rods, hydraulic cylinders, etc., which are known in the art. The specific structure of these mechanisms and the connection method with the fixed seat 31 and the lifting column 32 are all conventional technologies. Those skilled in the art can directly apply them without creative labor after reading this embodiment, and all of them can realize the basic function of driving the lifting column to rise and fall.

[0029] The preferred drive source for the lifting drive structure is a servo motor (not shown in the figure). The lifting mechanism 3 mainly uses a servo motor to control the spiral ascent of the lifting column 32, and its maximum diameter is only 450mm. Its principle is similar to that of a servo-controlled screw jack. With servo control, the lifting force is digitally presented, and the stroke accuracy reaches 1mm. It is also more suitable for two servo motors to lift I-beams in coordination. The above structural principle is well known to those skilled in the art, so it will not be described in detail. It should be noted that the top of the lifting column 32 has a tray with a diameter of 280mm and a weight of only 80kg, but it can lift 800kg, with strong lifting force. The supporting frame 33 is set on this tray. The entire lifting mechanism 3 has a folded height of only 540mm and can lift up to 5.5m, which fully meets the requirement of a maximum height of 5 meters from the floor to the ceiling in a nuclear power plant room. The lifting ratio is 1:11, and the storage volume is compact.

[0030] It should be noted that those skilled in the art should understand that the servo motor is only a preferred embodiment of the present invention, and not a limitation on the scope of protection. Under the condition of meeting the driving accuracy requirements, the driving device can also adopt any rotary driving source that can output rotational power and match the control system, such as a stepper motor, a brushless DC motor, or an AC servo motor. Those skilled in the art can conceive of replacing the servo motor in the embodiments of the present invention with the above-mentioned alternative driving sources without creative effort, so as to achieve the same lifting and lowering driving effect with the same function and the same means. These alternative solutions all fall within the scope of equivalent features of the present invention.

[0031] Due to the compact interior rooms and limited passageway width of nuclear power plants, large hoisting equipment cannot be used. Therefore, the overall dimensions of the airborne equipment in this embodiment are set at 1100x820x800mm. The equipment is small and compact, offering good terrain mobility. Please refer to [link / reference]. Figure 1 As shown, in order to save labor costs, this embodiment is also equipped with a walking mechanism 2, which can move freely between various construction points. Specifically, the bottom of the frame 1 is provided with fixed frames 10 on both sides, and the walking mechanism 2 is provided on the fixed frames 10. It includes a drive wheel 21, a driven wheel 22, and a track 20 that is driven by the two. The walking mechanism 2 designed with track 20 allows the whole machine to move freely in the nuclear power plant without manual handling. The track 20 is designed to be 100mm wide and has a load capacity of 1000kg.

[0032] In addition to the above, nuclear power plants also have stairwells and scaffolding, among other obstacles. Although the thresholds after scaffolding is erected are usually no higher than 20cm, this still tests the obstacle-crossing ability of the walking mechanism 2. Therefore, this embodiment also provides an adjustable-angle track design. Please refer to [link to relevant documentation]. Figure 1 As shown, the walking mechanism 2 also includes an adjusting wheel 23 that is driven and engaged inside the track 20, and an adjusting rod 24 that adjusts the tilt angle of the adjusting wheel 23. One end of the adjusting rod 24 is rotatably mounted on the fixed frame 10, and the other end is driven and connected to the adjusting wheel 23. The adjusting wheel 23 is located at the top of the track 20 near the direction of the machine's forward movement. When the machine needs to cross a scaffold threshold or go up a staircase, it can pass by adjusting the tilt angle of the track. In this embodiment, the tilt angle can be adjusted up to 30°, which can easily cope with scaffolds up to 20cm high, move freely, and is extremely suitable for nuclear power plant construction work.

[0033] Please see Figure 6 As shown, in a preferred embodiment, the climbing frame 5 is provided with a connecting frame 51 at the rear. The connecting frame 51 has a movable groove 52 with an arc-shaped sidewall within the winding range of the traction member 40. The wire rope will shift within the front and rear range during the lifting and lowering process with the cooperating frame 33. Therefore, this embodiment also provides a movable groove 52 to prevent the traction member 40 from rubbing against the components due to long-term operation. At the same time, the arc-shaped sidewall is provided so that it will not rub directly against the sharp sidewall, thereby causing wear. As a feasible embodiment, the arc-shaped sidewall can also be chamfered.

[0034] It should be noted that, as a preferred embodiment, the airborne equipment of the present invention is also equipped with a wireless remote control function, which allows the device to be controlled for operation by manually operating the remote control.

[0035] The airborne equipment of this invention employs two devices working in tandem. Its operating mode involves first supporting the ceiling to create a rigid support between the ceiling and the ground (ensuring safety during subsequent hoisting), and then using a hoisting system (cooperating frame 33) above the rigid support to perform the hoisting operation. This method is particularly suitable for confined spaces with ceilings, such as nuclear power and hydropower plants. It solves the problem of large equipment being unable to enter and requiring manual scaffolding erection. The specific operating method is as follows: 1. Mark the position using a crosshair laser level, and then transport the I-beam roughly to the marked position; 2. Using the remote control, the two main bodies of the equipment are moved to the two sides of the I-beam respectively, so that the pallet frame 62 is aligned with the two sides of the I-beam, and the pallet frame 62 on the material pallet 6 is lowered to the lowest position. 4. Move the main body of the control equipment toward the I-beam so that the insulating strip 64 on the pallet frame 62 is in full contact with the I-beam. Then, adjust the self-centering clamp 63 on the pallet frame 62 through the insertion hole 65 and clamp the bottom of the I-beam. 5. The remote-controlled lifting mechanism 3 enables the lifting columns 32 of the two main equipment bodies to be simultaneously lifted to the ceiling, so that the ceiling and the ground form a rigid support in advance, ensuring the safety of construction operations. 6. Securely attach the hook on the traction component 40 of the drive mechanism 4 to the fixing hole 66 on the pallet frame 62, and then operate the drive mechanism 4 to drive the material pallets 6 on the two main bodies of the equipment to rise and fall synchronously to about 100 mm from the ceiling. 7. Adjust the self-centering clamp 63 through the insertion hole 65 to loosen the I-beam. With the help of a cross laser level, adjust the I-beam to the corresponding position of the embedded part and push it to the working position before proceeding to the welding process. 8. After the welding process is completed, lower the lifting mechanism 3 and the climbing frame 5 on the main body of the equipment to the initial position, and then remotely control the main body of the equipment to the next construction point.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
