Description

Technical Field

[0001] This utility model relates to the field of nuclear power equipment installation engineering technology, specifically to a new type of anti-misalignment tooling for positioning rail beams. Background Technology

[0002] After the positioning, adjustment, and drilling of the rail support beam for the nuclear power plant (Hualong One) ring crane are completed, the shims between the rail support beam and the bracket need to be replaced with pre-processed adjusting shims. Previously, the rail support beam had to be jacked up to a position where the shims could be removed, and then the holes of the pre-processed shims were aligned with the holes of the bracket for replacement. However, when drilling the bracket, the bidirectional adjustment device has been removed. Under stress, the rail support beam will shift. During the replacement of the adjusting shims, the rail support beam will also deviate due to jacking and lowering. The accumulation of multiple offsets and deviations may cause the holes in the rail support beam and the holes in the bracket to shift, making it impossible for the bolts to connect the bracket and the rail support beam, thus affecting the subsequent construction of the nuclear power plant. Utility Model Content

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A novel anti-misalignment fixture for a rail support beam includes a top plate, a semi-circular boss, and a pin. The semi-circular boss is adjustablely mounted on the top plate via a first adjustable mechanism and can fit into the elongated hole of the rail support beam. The pin is adjustablely mounted on the top plate via a second adjustable mechanism, and its length can penetrate through the screw holes on the rail support beam, the adjusting pad, and the bracket.

[0006] Furthermore, the first adjustable mechanism includes an elongated hole on the top plate, a first connecting hole on the semi-circular boss, and a first connecting member, the first connecting member being used to connect the top plate and the semi-circular boss.

[0007] Furthermore, the second adjustable mechanism includes an elongated hole on the top plate, a second connecting hole on the pin, and a second connecting member, the second connecting member being used to connect the top plate and the pin.

[0008] Furthermore, the semi-circular boss has two parts, and one side with the arc surface faces outward.

[0009] Furthermore, the pin has a tapered structure at the end opposite to the second connecting hole.

[0010] Furthermore, the diameters of the semi-circular boss and the pin are both greater than the width of the oblong hole, and the widths of the first connector and the second connector are both greater than the width of the oblong hole.

[0023] like Figure 1-4 As shown, a novel anti-misalignment fixture for a rail support beam includes a top plate 1, a semi-circular boss 2, and a pin 3. The semi-circular boss 2 is adjustablely mounted on the top plate 1 via a first adjustable mechanism and can fit into the elongated hole 4 of the rail support beam to prevent the rail support beam from misaligning during lifting and lowering. The pin 3 is adjustablely mounted on the top plate 1 via a second adjustable mechanism, and its length can penetrate through the screw holes on the rail support beam, the adjusting pad, and the bracket, so that the three screw holes always maintain a certain coaxiality.

[0024] Specifically, the first adjustable mechanism includes an elongated hole 4 on the top plate 1, a first connecting hole 5 on the semi-circular boss 2, and a first connecting member 6. The first connecting member 6 is used to connect the top plate 1 and the semi-circular boss 2. The semi-circular boss 2 can be adjusted in position through the first adjustable mechanism to adapt to various situations.

[0025] In this embodiment, the first connecting hole 5 is a bolt hole, and the corresponding first connecting member 6 is a bolt adapted to the bolt hole. The diameter of the semi-circular boss 2 is larger than the width of the oblong hole 4, and the width of the bolt head is larger than the width of the oblong hole 4. In this way, the semi-circular boss 2 can fit against the lower surface of the top plate 1 and be fastened by bolts. When it is necessary to adjust the position of the semi-circular boss 2, the first connecting member 6 can be loosened and moved along the oblong hole 4 to adjust the position of the semi-circular boss 2 to adapt to various situations.

[0026] Specifically, the second adjustable mechanism includes an elongated hole 4 on the top plate 1, a second connecting hole 7 on the pin 3, and a second connecting member 8. The second connecting member 8 is used to connect the top plate 1 and the pin 3. The position of the pin 3 can be adjusted through the second adjustable mechanism to adapt to various situations.

[0027] In this embodiment, the second connecting hole 7 is a bolt hole, and the corresponding second connecting member 8 is a bolt adapted to the bolt hole. The diameter of the pin 3 is larger than the width of the elongated hole 4, and the width of the bolt head is larger than the width of the elongated hole 4. In this way, the pin 3 can fit against the lower surface of the top plate 1 and be fastened by the bolt. When it is necessary to adjust the position of the pin 3, the second connecting member 8 can be loosened and moved along the elongated hole 4 to adjust the position of the pin 3 to adapt to various situations.

[0028] In this embodiment, there are two semi-circular bosses 2, with one side of the boss facing outward, which can fit into the elongated hole 4 of the rail beam.

[0029] In this embodiment, the pin 3 has a tapered structure at the end opposite to the second connecting hole 7. The tapered structure design makes it easier for the pin to be inserted into the screw holes on the rail beam, adjusting pad, and bracket.

[0030] In this embodiment, the top plate 1 is a steel plate with a length of 150mm, a width of 75mm, and a thickness of 10mm; the semi-circular boss 2 is a semi-circular steel with a thickness of 35mm and a diameter of 51mm; and the pin 3 is a pin with a length of 180mm and a diameter of 50mm.

[0031] This utility model relates to a novel anti-misalignment fixture for rail bearing beams, the working principle of which is explained in conjunction with the accompanying drawings:

[0032] Adjust the positions of the two semi-circular bosses 2 and pins 3 in the elongated holes 4 according to the actual hole positions, so that the two semi-circular bosses 2 can completely fit the elongated holes 4 of the rail beam, and the pins 3 can connect the screw holes of the rail beam, the adjusting pad and the bracket. The two semi-circular bosses 2 and pins 3 are fixed on the top plate 1 by the first connector 6 and the second connector 8.

[0033] A rail support beam is supported by three brackets. Before replacing the adjusting shims, use a tool to connect the holes at both ends of the rail support beam to the holes in the brackets. After that, lift the rail support beam, remove the shim of the middle bracket, replace the adjusting shim, and then use a tool to connect the middle rail support beam, the adjusting shim, and the bracket screw holes. After that, remove the tooling at both ends in sequence and replace the adjusting shims to ensure the coaxiality of the holes.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
