[0033] Reference below Figures 1 to 4 The transport tooling for a GIL linear unit according to an embodiment of the utility model is described.

[0034] refer to Figures 1 to 4 As shown, the transport tooling for the GIL linear unit according to the embodiment of the utility model includes a support frame 100 , a walking mechanism 200 , a tensioning mechanism 300 and a rope 400 .

[0035] Among them, the support frame 100 can be provided with one or more placement grooves 101, for example, two placement grooves 101, the placement groove 101 is used to place the GIL linear unit 500, and the support frame 100 is provided with a first connecting portion 102 on one side of the placement groove 101. When the GIL linear unit 500 is placed in the placement groove 101, the first connecting portion 102 can be located below one side of the GIL linear unit 500.

[0036] The walking mechanism 200 is disposed on the support frame 100 for walking, thereby driving the support frame 100 to move, thereby driving the GIL linear unit 500 to move.

[0037] The tensioning mechanism 300 includes a mounting portion 301 and a movable portion 302. The mounting portion 301 is arranged on the support frame 100 and is located on the side of the mounting groove 101 away from the first connecting portion 102. The movable portion 302 is movably and adjustably installed on the mounting portion 301. For example, it can be rotatably or slidably arranged on the mounting portion 301. The movable portion 302 is provided with a second connecting portion 303. When the GIL linear unit 500 is placed in the mounting groove 101, the second connecting portion 303 can be located below the side of the GIL linear unit 500 away from the first connecting portion 102.

[0038] One end of the rope 400 is connected to the first connection part 102 , and the other end is connected to the second connection part 303 . When the GIL linear unit 500 is placed in the placement groove 101 , the rope 400 is used to be wound around the side of the GIL linear unit 500 away from the placement groove 101 .

[0039] The movable portion 302 can be moved to tighten the rope 400 so that the rope 400 is closely attached to the GIL linear unit 500 , and the rope 400 can cooperate with the mounting groove 101 to bind and fix the GIL linear unit 500 .

[0040] In the present invention, when the GIL linear unit 500 needs to be transported, a plurality of transport jigs can be arranged side by side, and then different positions of the GIL linear unit 500 in the length direction are placed in the placement grooves 101 of different support frames 100, and then the two ends of the rope 400 are respectively connected to the first connection part 102 and the second connection part 303, and the rope 400 is arranged around the side of the GIL linear unit 500 away from the placement groove 101, and then the movable part 302 is adjusted to tighten the rope 400 so that the rope 400 is close to the GIL linear unit 500, and the binding and fixing of the GIL linear unit 500 can be completed, and finally the GIL linear unit 500 can be driven to move by the walking mechanism 200. The transport jig for the GIL linear unit according to the embodiment of the present invention is not only simple in structure and low in cost, but also more convenient for transporting the GIL linear unit 500.

[0041] In some embodiments of the present invention, Figures 2 to 4 As shown, the movable part 302 is rotatably mounted on the mounting part 301 , and the tensioning mechanism 300 further includes a locking member 304 , which is disposed between the movable part 302 and the mounting part 301 to lock the movable part 302 after the movable part 302 rotates to a set angle.

[0042] In this embodiment, when the GIL linear unit 500 is placed in the placement groove 101, and the two ends of the rope 400 are respectively connected to the first connection part 102 and the second connection part 303, and the rope 400 is arranged on the side of the GIL linear unit 500 away from the placement groove 101, the movable part 302 is rotated, and the movable part 302 can drive the second connection part 303 to rotate, and the second connection part 303 can drive the rope 400 to move around the rotation axis of the movable part 302, thereby gradually tightening the rope 400. When the tension of the rope 400 reaches a preset value, the movable part 302 is locked by the locking member 304, and the movable part 302 can be restricted from continuing to rotate, so that the rope 400 is kept in a state of being close to the GIL linear unit 500. The structure is simple, the operation is convenient, and the effect of tightening the rope 400 is good.

[0043] It should be noted that, in some other embodiments of the present invention, the movable portion 302 may also be movable in other adjustment modes, for example, it may be slidably mounted on the mounting portion 301 .

[0044] In some embodiments of the present invention, Figures 2 to 4 As shown, the movable part 302 is provided with a plurality of first positioning holes 305, and the mounting part 301 is correspondingly provided with a plurality of second positioning holes 306. The plurality of first positioning holes 305 and the plurality of second positioning holes 306 are all arranged circumferentially along the rotation axis of the movable part 302. During the rotation of the movable part 302, the first positioning holes 305 can be aligned with different second positioning holes 306. The locking member 304 includes a plurality of latches 307, and the latches 307 are inserted into the aligned first positioning holes 305 and second positioning holes 306.

[0045] In this embodiment, when the movable part 302 is rotated to tighten the rope 400 so that the tension of the rope 400 reaches near the preset value, the first positioning hole 305 is just aligned with one of the second positioning holes 306, and then the pin 307 can be inserted. The structure is simple and easy to operate. Moreover, since a plurality of first positioning holes 305 and a plurality of second positioning holes 306 are provided, even if the movable part 302 is rotated to different angles, it can be locked, which is more convenient to use and can be applied to GIL linear units 500 of different diameters, and has better practicality.

[0046] It should be noted that in some other embodiments of the present invention, the locking member 304 may also be other structures, for example, it may be a bolt.

[0047] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the movable part 302 includes a rotating shaft 308 and a tightening disk 309. The rotating shaft 308 is rotatably mounted on the mounting part 301. The second connecting part 303 is arranged on the rotating shaft 308. The tightening disk 309 is arranged on the rotating shaft 308 and is coaxial with the rotating shaft 308. A plurality of first positioning holes 305 are arranged on the tightening disk 309 and are arranged along the circumference of the tightening disk 309.

[0048] For example, the rotating shaft 308 can be installed on the mounting portion 301 through an oil-free sleeve, so as to reduce the stuck phenomenon of the rotating shaft 308 and the excessive radial friction force. The second connecting portion 303 can be arranged on the outer wall of the rotating shaft 308, and there is a gap between the second connecting portion 303 and the axis of the rotating shaft 308. The tightening disk 309 can be in the shape of a disk, and the tightening disk 309 can be coaxially arranged at the end of the rotating shaft 308. The middle position of the tightening disk 309 can be provided with a hexagonal column for facilitating the wrench to rotate the tightening disk 309. In this embodiment, such a configuration not only makes it more convenient to rotate the movable portion 302, but also makes it more effective to tighten the rope 400.

[0049] It should be noted that in some other embodiments of the present invention, the movable portion 302 may also be other suitable shapes. For example, the movable portion 302 is directly set as a disc, the disc is directly rotatably mounted on the mounting portion 301, and the second connecting portion 303 is set on the disc.

[0050] In some embodiments of the present invention, Figure 4 As shown, a socket is provided at one end of the rotating shaft 308 away from the tightening disk 309, and a cotter pin 310 is inserted into the socket. The cotter pin 310 and the tightening disk 309 are respectively located on the opposite sides of the mounting portion 301, and the rotating shaft 308 is sleeved with a washer 311 located between the cotter pin 310 and the mounting portion 301.

[0051] In this embodiment, when installing the movable part 302, the rotating shaft 308 of the movable part 302 is inserted into the installation part 301, and then the washer 311 is sleeved on the outside of the rotating shaft 308, and finally the cotter pin 310 is inserted into the socket. The installation is convenient, and correspondingly, when the movable part 302 needs to be disassembled, the operation is also convenient, and the practicality is better.

[0052] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, a flexible buffer pad 103 is attached to the surface of the placement groove 101. In this embodiment, the flexible buffer pad 103 is attached to the surface of the placement groove 101. After the GIL linear unit 500 is placed in the placement groove 101, the rigid impact force between the GIL linear unit 500 and the support frame 100 can be reduced, thereby reducing the damage to the GIL linear unit 500 or the support frame 100.

[0053] It should be noted that the flexible buffer pad 103 can be made of engineering plastics, which have high mechanical strength, good wear resistance and longer service life. In addition, the flexible buffer pad 103 can also be made of other suitable materials, such as elastic rubber.

[0054] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the corner positions on both sides of the top of the support frame 100 are respectively provided with protection pads 104, the first connection part 102 and the second connection part 303 are respectively located below the two protection pads 104, and the rope 400 is arranged around the two protection pads 104. In order to make the rope 400 lock the GIL linear unit 500 more effectively, the first connection part 102 and the second connection part 303 can be arranged on both sides of the support frame 100 and lower than the top surface of the support frame 100, so that the rope 400 is easily arranged around the corner positions on both sides of the top of the support frame 100, and then when the rope 400 moves and is tightened, there will be friction between the support frame 100 and the rope 400, which not only affects the tightening of the rope 400, but also easily causes the support frame 100 and the rope 400 to wear during long-term use.

[0055] In this embodiment, protection pads 104 are respectively provided at the corners on both sides of the top of the support frame 100, and the rope 400 will be arranged around the two protection pads 104. The protection pads 104 can be made of wear-resistant and relatively smooth engineering plastics or other suitable materials. Therefore, when the rope 400 is tightened, not only can the rope 400 move more smoothly, but also the wear on the support frame 100 and the rope 400 can be reduced.

[0056] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the placement groove 101 is set as a V-shaped groove. Such a setting can not only effectively limit the rolling of the GIL linear unit 500, but also has a better effect of locking the GIL linear unit 500, and can be applied to GIL linear units 500 of different diameters, and the GIL linear unit 500 can automatically find the most suitable placement position, which is more applicable and more convenient to use.

[0057] In some embodiments of the present invention, Figure 3As shown, the support frame 100 includes a base 105 and at least two support parts 106, and the at least two support parts 106 are arranged side by side and at intervals on the base 105. Each support part 106 is provided with a placement groove 101. Correspondingly, each support part 106 can be provided with a first connecting part 102, a tensioning mechanism 300 and a rope 400. In this embodiment, such a configuration not only makes the placement of the GIL linear unit 500 more stable, but also when the outer side wall of the GIL linear unit 500 is provided with a protruding component, the protruding component can be located between two adjacent support parts 106, thereby making the placement of the GIL linear unit 500 more convenient.

[0058] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the walking mechanism 200 includes a plurality of universal wheels 201, and the plurality of universal wheels 201 are arranged at the bottom end of the support frame 100. Specifically, the universal wheels 201 can rotate 360° around the vertical axis, thereby enabling the support frame 100 to move in different directions, which is more convenient to use.

[0059] It should be noted that in some other embodiments of the present invention, the walking mechanism 200 may also be other structures, for example, it may also be set as ordinary casters or as tracks, which will not be described in detail here.

[0060] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
