[0028] See Figures 1 to 4 This utility model discloses a nuclear power plant component transfer vehicle, which is suitable for the transfer of nuclear power plant components, including but not limited to pipes, flanges, instrument cabinets, and storage cabinets.
[0029] The nuclear power plant component transfer vehicle includes a first installation platform 10, a second installation platform 20, an adjustment mechanism 30, and a traction mechanism 40.
[0030] Both the first mounting platform 10 and the second mounting platform 20 can be rectangular plate structures, with multiple reinforcing ribs at their bottom. Both platforms can be made of high-strength steel, and their upper surfaces are flat. Fixing mechanisms can also be added to the upper surfaces of the platforms to limit the movement of the nuclear power plant components. Alternatively, after the components are installed on the upper surfaces, they can be secured with ropes or similar means; specific limitations are not specified here. In some embodiments, protective pads may also be provided on the first mounting platform 10 and the second mounting platform 20.
[0031] Both the first mounting platform 10 and the second mounting platform 20 are provided with first moving wheels 50, which are located at the bottom of the first mounting platform 10 and the second mounting platform 20 along their length direction. The first mounting platform 10 has a plurality of first supports 11 on the side facing the second mounting platform 20, and these first supports 11 are spaced apart along the length direction of the first mounting platform 10. The second mounting platform 20 has a plurality of second supports 21 on the side facing the first mounting platform 10, and these second supports 21 are spaced apart along the length direction of the second mounting platform 20.
[0032] The adjustment mechanism 30 is located between the first mounting platform 10 and the second mounting platform 20. The adjustment mechanism 30 may include a plurality of adjustment seats 31, a plurality of first expansion rods 32, a plurality of second expansion rods 33, and an adjustment connecting rod 34. The plurality of adjustment seats 31 are arranged at intervals along the length of the first mounting platform 10 and the second mounting platform 20. The two ends of the first expansion rods 32 are respectively connected to the first support 11 and the first end of the adjustment seat 31. The two ends of the second expansion rods 33 are respectively connected to the second support 21 and the second end of the adjustment seat 31.
[0033] The traction mechanism 40 includes a fixed base 41, a support base 42, and a pull rod 43. The support base 42 is disposed on the fixed base 41 and has a threaded hole 421. The pull rod 43 is connected to the fixed base 41. The adjusting connecting rod 34 passes through the threaded hole 421 and all the adjusting bases 31. The adjusting connecting rod 34 is used to drive the first expansion rod 32 and the second expansion rod 33 to move, so that the first mounting platform 10 and the second mounting platform 20 are relatively close or relatively far apart. This allows the size of the bearing surface formed by the first mounting platform 10 and the second mounting platform 20 to be adjusted, thereby improving its applicability and practicality, and reducing equipment costs and management costs.
[0034] In some embodiments, the adjusting seat 31 is generally rectangular in shape and has a central through hole 311 for the adjusting connecting rod 34 to pass through.
[0035] like Figure 4 As shown, in some embodiments, the first support 11 is provided with a first groove 111, the second support 21 is provided with a second groove 211, the first end of the adjusting seat 31 is provided with a third groove 312, and the second end of the adjusting seat 31 is provided with a fourth groove 313.
[0036] The first axial end of the first expansion rod 32 is rotatably mounted in the first groove 111, the second axial end of the first expansion rod 32 is rotatably mounted in the third groove 312, the first axial end of the second expansion rod 33 is rotatably mounted in the third groove 312, and the second axial end of the second expansion rod 33 is rotatably mounted in the fourth groove 313. The rotatable mounting method described above can be achieved by rotating the rod through a mounting shaft.
[0037] like Figure 4 As shown, in some embodiments, the adjusting connecting rod 34 is provided with a plurality of slots 341, and two adjacent slots 341 define a mounting position for the adjusting seat 31. The adjusting mechanism 30 also includes a plurality of limiting plates 35, which are snapped onto the slots 341 and connected to the adjusting seat 31. The limiting plate 35 can be snapped onto the slots 341 and then detachably connected to the end face of the adjusting seat 31 by bolts or screws, making the assembly of the adjusting mechanism 30 more convenient and enabling modular production and assembly.
[0038] In some embodiments, the outer circumferential surface of the adjusting connecting rod 34 is provided with external threads to be threadedly connected and fixed to the threaded hole 421, thereby realizing threaded adjustment. In some embodiments, the support base 42 may also be a nut seat.
[0039] like Figure 1 As shown, in some embodiments, the first end of the adjusting connecting rod 34 protrudes from the support base 42. The first end of the adjusting connecting rod 34 is provided with a connecting part 342 connected to the operating device. The operating device may include an operating wrench or an intelligent torque wrench. After the operating device is connected to the connecting part 342, it can drive the adjusting connecting rod 34 to move axially, thereby realizing the contraction or expansion of the first expansion rod 32 and the second expansion rod 33. In turn, the size of the bearing surface formed by the first mounting platform 10 and the second mounting platform 20 can be adjusted to improve its applicability and practicality.
[0040] In some embodiments, the longitudinal section of the connecting portion 342 is tetragonal, pentagonal, hexagonal, heptagonal, or octagonal. Preferably, the longitudinal section of the connecting portion 342 is hexagonal, that is, the connecting portion 342 may be, but is not limited to, a hexagonal head, which can be operated with a hexagonal slot wrench.
[0041] like Figure 1 As shown, in some embodiments, the pull rod 43 includes a rod body 431, the lower end of which is provided with a U-shaped portion 432, the U-shaped portion 432 being rotatably connected to the fixed base 41, and the upper end of which is provided with a pull ring portion 433.
[0042] In some embodiments, the mounting base 41 is provided with a second caster wheel 60.
[0043] In some embodiments, both the first moving wheel 50 and the second moving wheel 60 are selected as moving wheels with a self-locking function. Preferably, the first moving wheel 50 includes a caster wheel or a steering wheel; and / or, the second moving wheel 60 includes a caster wheel or a steering wheel. For example, the first moving wheel 50 may be entirely composed of caster wheels, and the second moving wheel 60 may be entirely composed of caster wheels. Alternatively, the first moving wheel 50 may be entirely composed of steering wheels, and the second moving wheel 60 may be entirely composed of steering wheels. Alternatively, the first moving wheel 50 may be entirely composed of caster wheels, and the second moving wheel 60 may be entirely composed of steering wheels. Installing steering wheels enables the automatic movement of the nuclear power plant equipment transfer vehicle powered by electricity.
[0044] When the first moving wheel 50 and the second moving wheel 60 are in a self-locking state, the adjusting connecting rod 34 can be manually or electrically rotated by an operating device (such as a torque wrench). Each of the first supports 11 and the second supports 21 will move closer to or further away from the support base 42, causing the angle between the first expansion rod 32, the second expansion rod 33, and the adjusting connecting rod 34 to decrease or increase. This allows for adjustment of the distance between the first mounting platform 10 and the second mounting platform 20 to accommodate nuclear power plant components of different sizes. In addition, a smaller distance between the first mounting platform 10 and the second mounting platform 20 can improve the passability of the nuclear power plant component transfer vehicle in narrow passages.
[0045] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
