Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts also belong to the scope of protection of the present application.

[0032] As Figure 1 and Figure 2 shown, a high-voltage bushing packing box disclosed in the present application includes a bottom frame 1. The bottom frame 1 is of a rectangular structure. A top support unit 2 and a tail support unit 3 are sequentially arranged in the bottom frame 1 along its length direction. A plurality of high-voltage bushing bodies 4 are arranged between the top support unit 2 and the tail support unit 3 along the width direction of the bottom frame 1; the distance between the top support unit 2 and the tail support unit 3 is equal to the distance from the top end to the tail end of the high-voltage bushing body 4; after the top ends and tail ends of the plurality of high-voltage bushing bodies 4 are respectively placed on the top support unit 2 and the tail support unit 3, the top support unit 2 and the tail support unit 3 can simultaneously limit and fix all the high-voltage bushing bodies 4; a protection frame 5 is detachably installed above the bottom frame 1, and closed iron plates 6 are installed on the periphery and top of the protection frame 5. The protection frame 5 installed with the closed iron plates 6 can simultaneously protect the plurality of high-voltage bushing bodies 4 on the bottom frame 1.

[0033] In the above embodiments, the bottom frame 1 of the rectangular structure in the present application is welded by multiple channel steels, and the protection frame 5 that can protect multiple high-voltage bushing bodies 4 on the bottom frame 1 is welded by multiple angle steels. Moreover, the four angle steels circumferentially at the lower end of the protection frame 5 and the bottom frame 1 are detachably connected by bolts and nuts, which is very convenient for installation and disassembly.

[0034] When an enterprise needs to package the high-voltage bushings before transportation, the workers of the enterprise only need to sequentially place the prepared multiple high-voltage bushing bodies 4 on the top support unit 2 and the tail support unit 3 by using tools (the distance between the top support unit 2 and the tail support unit 3 can be similar to or equal to the distance from the top end to the tail end of the high-voltage bushing body 4, as long as it is ensured that the top end and the tail end of the high-voltage bushing body 4 can be respectively erected on the top support unit 2 and the tail support unit 3). The top support unit 2 and the tail support unit 3 of the present application can simultaneously limit and fix the multiple high-voltage bushing bodies 4, which can effectively improve the packaging efficiency of the high-voltage bushing bodies 4. After fixing the multiple high-voltage bushing bodies 4, the protection frame 5 installed with the closed iron plate 6 is covered outside the multiple high-voltage bushings and fixed to the bottom frame 1 by bolts and nuts.

[0035] After the transportation is completed, the protection frame 5 is opened from the bottom frame 1, and the restrictions of the top support unit 2 and the tail support unit 3 on the high-voltage bushing body 4 are released, and then the high-voltage bushing can be taken out. If the high-voltage bushing needs to be transported again later, the above operations can be repeated. Compared with the wooden frames simply spliced together in the prior art, the packing box of the present application has significantly higher strength and packing speed, and can be reused multiple times later, with better economy and environmental protection.

[0036] Further, as Figure 2 and Figure 3 shown, the top support unit 2 includes a first channel steel 21. The two ends of the first channel steel 21 are respectively fixedly connected to a pair of opposite sides in the width direction of the bottom frame 1. The opening of the first channel steel 21 faces upward. A first wooden clamping plate 22 is fixedly installed in the opening of the first channel steel 21. A plurality of first grooves 23 are uniformly arranged on the upper side of the first wooden clamping plate 22. The top ends of the multiple high-voltage bushing bodies 4 can be respectively placed in the multiple first grooves 23;

[0037] A first portal-shaped limiting frame 24 is arranged on the side of the first channel steel 21 away from the tail support unit 3. The lower end of the first portal-shaped limiting frame 24 is installed on the first channel steel 21. The lower side of the horizontal rod of the first portal-shaped limiting frame 24 abuts against the end rods at the top ends of the multiple high-voltage bushing bodies 4 at the same time. The two vertical rods of the first portal-shaped limiting frame 24 abut against the mutually remote sides of the end rods at the top ends of the two high-voltage bushing bodies 4 on both sides in the width direction of the bottom frame 1.

[0038] In the above embodiments, both ends of the first channel steel 21 are fixedly welded to the opposite side walls in the width direction of the bottom frame 1. The first wooden clamping plate 22 can be inserted into the first channel steel 21 through the upward opening of the first channel steel 21, and they are fixed together by bolts and nuts. In this way, the first wooden clamping plate 22 can provide a stable supporting force for the top end of the high-voltage bushing body 4 placed thereon through the first channel steel 21. The cross-sectional shape of the first groove 23 on the first wooden clamping plate 22 in the vertical direction is an isosceles triangle. When the top end of the high-voltage bushing body 4 is placed in the first groove 23, both waists in the groove are tangent to the edge line of the circular top end of the high-voltage bushing body 4. While providing a stable supporting force for the top end of the high-voltage bushing body 4, the high-voltage bushing body 4 will not easily shake in the first groove 23.

[0039] The first portal-shaped limiting frame 24 on the side of the first channel steel 21 away from the tail support unit 3 is composed of two vertical rods and a horizontal rod. The vertical rods and the horizontal rod are fixedly connected by bolts and nuts, and the vertical rods and the first channel steel 21 are also fixedly connected by bolts and nuts. This is very convenient for packaging and removing the high-voltage bushing. For example, after placing the high-voltage bushing body 4, the two vertical rods can be first abutted against the mutually remote sides of the upper end head rods of the two high-voltage bushing bodies 4 located on both sides in the width direction of the bottom frame 1, and then the two vertical rods and the first channel steel 21 are fixedly connected by bolts and nuts. Then the horizontal rod is clamped on the upper side of the end head rods at the top ends of multiple high-voltage bushing bodies 4, and then the two ends of the horizontal rod are respectively fixedly connected to the upper ends of the two vertical rods by bolts and nuts. At this time, the first portal-shaped limiting frame 24 composed of the horizontal rod and the vertical rods can simultaneously limit and fix multiple high-voltage bushing bodies 4, preventing them from accidentally detaching from the corresponding first groove 23 during transportation and improving the safety during their transportation.

[0040] In actual use, a plurality of through holes can be provided in the length direction of the first channel steel 21 and in the length direction of the vertical rods of the first portal-shaped limiting frame 24. In this way, when the specifications of the high-voltage bushing bodies 4 placed on the first wooden clamping plate 22 change, the worker can also make the first portal-shaped limiting frame 24 well limit and fix the high-voltage bushing bodies 4 with changed specifications by adjusting the connection positions of the vertical rods and the first channel steel 21 in the first portal-shaped limiting frame 24 and the connection points of the horizontal rod and the vertical rods.

[0041] Further, as Figure 2 and Figure 4As shown, the tail support unit 3 includes a second channel steel 31. The two ends of the second channel steel 31 are respectively fixedly connected to a relative side in the width direction of the bottom frame 1. The opening direction of the second channel steel 31 is the same as that of the first channel steel 21. A second wooden clamping plate 32 is fixedly installed in the opening of the second channel steel 31. A plurality of second grooves 33 are evenly arranged on the upper side of the second wooden clamping plate 32. The tails of a plurality of high-voltage bushing bodies 4 can be respectively placed in the plurality of second grooves 33;

[0042] On the side of the second channel steel 31 away from the first channel steel 21, there is a second portal-shaped limiting frame 34. The lower end of the second portal-shaped limiting frame 34 is installed on the second channel steel 31. The lower side of the horizontal rod of the second portal-shaped limiting frame 34 is simultaneously abutted against the end rods at the tails of a plurality of high-voltage bushing bodies 4. The two vertical rods of the second portal-shaped limiting frame 34 are respectively abutted against the mutually remote sides of the end rods at the tails of the two high-voltage bushing bodies 4 on both sides in the width direction of the bottom frame 1.

[0043] In the above embodiments, the principle of limiting and supporting the tail of the high-voltage bushing body 4 by the tail support unit 3 is the same as that of limiting and supporting the top of the high-voltage bushing body 4 by the top support unit 2. The main difference between the tail support unit 3 and the top support unit 2 is the dimensional difference between the second wooden clamping plate 32 and the second portal-shaped limiting frame 34. This difference mainly comes from the dimensional difference between the tail of the high-voltage bushing body 4 acted on by the tail support unit 3 and the top of the high-voltage bushing body 4 acted on by the top support unit 2. Therefore, for the working principle of the tail support unit 3, reference can be made to the relevant content of the working principle of the top support unit 2 in the previous embodiment. In addition, the dimensions of the first wooden clamping plate 22 and the second wooden clamping plate 32 are such that when the two ends of the high-voltage bushing body 4 are respectively placed on them, the axis of the high-voltage bushing is parallel to the plane where the bottom frame 1 is located, as Figure 6 shown, so that the state of the high-voltage bushing body 4 will be more stable during transportation.

[0044] Furthermore, as Figures 2 - 4 shown, the distance between the mutually approaching ends of the first wooden clamping plate 22 and the second wooden clamping plate 32 is less than the distance between the tail end and the top end of the high-voltage bushing body 4, and the distance between the mutually remote ends of the first wooden clamping plate 22 and the second wooden clamping plate 32 is greater than the distance between the tail end and the top end of the high-voltage bushing body 4.

[0045] In the above embodiments, when the distance between the first wooden clamping plate 22 and the second wooden clamping plate 32 of the present application meets the above conditions, there will be gaps between the top end and the tail end of the high-voltage bushing body 4 and the first portal-shaped limiting frame 24 and the second portal-shaped limiting frame 34 on the mutually remote sides of the first wooden clamping plate 22 and the second wooden clamping plate 32. In this way, during transportation, it can prevent the first portal-shaped limiting frame 24 and the second portal-shaped limiting frame 34 made of metal from squeezing against the porcelain surface of the high-voltage bushing body 4 and causing damage to it.

[0046] Furthermore, as Figure 3 and Figure 4 shown, buffer cushions 7 are provided between the top end of the high-voltage bushing body 4 and the first portal-shaped limit frame 24, and between the tail end of the high-voltage bushing body 4 and the second portal-shaped limit frame 34.

[0047] In the above embodiments, buffer cushions 7 are provided in the gaps between the two ends of the high-voltage bushing body 4 and the first portal-shaped limit frame 24 and the second portal-shaped limit frame 34. The buffer cushions 7 can be rubber blocks or wooden blocks, so that during transportation, the ends of the high-voltage bushing can be further protected to prevent accidental sliding along the axial direction and collision with the first portal-shaped limit frame 24 or the second portal-shaped limit frame 34.

[0048] Furthermore, as Figure 2 and Figure 6 shown, the thicknesses of the first channel steel 21 and the second channel steel 31 are both smaller than the height of the bottom frame 1, and a metal bottom plate 8 made of the same material as the closed iron plate 6 on the protection frame 5 is fixedly installed at the lower end of the bottom frame 1.

[0049] In the above embodiments, the thicknesses of the first channel steel 21 and the second channel steel 31 are both smaller than the height of the bottom frame 1, and the upper end surfaces of the first channel steel 21 and the second channel steel 31 are flush with the upper end surface of the bottom frame 1. In this way, there is enough space for installing the metal bottom plate 8 in the part where the lower end of the bottom frame 1 extends beyond the first channel steel 21 and the second channel steel 31, which can make the appearance of the packing box neat and beautiful. And after packaging multiple high-voltage bushings with the protection frame 5 and the bottom frame 1, the high-voltage bushing body 4 can be completely isolated from the external environment during transportation, which can further improve the protection effect on the high-voltage bushing body 4.

[0050] Furthermore, as Figure 5 and Figure 6 shown, two mutually parallel third channel steels 9 are provided along the length direction below the bottom frame 1, and there is a gap between the two third channel steels 9; the openings of the third channel steels 9 are all downward, and support cushion woods 10 are fixedly installed in the openings of the third channel steels 9.

[0051] In the above embodiments, the two third channel steels 9 support the entire box body through the support cushion woods 10. In this way, during transportation, when there is a certain bump, the support cushion woods 10 can play a good buffering role compared with the support blocks made of rigid materials, so as to protect the high-voltage bushing body 4 in the packing box. And during transportation, if it is necessary to tie the packing box circumferentially with a rope, the space generated by the support cushion woods 10 and the third channel steels 9 lifting the entire box body upward will facilitate the workers to thread the tying rope. After being transported to the designated position, this space also facilitates the special forklift to quickly insert into the bottom of the packing box so as to quickly unload the packing box.

[0052] Furthermore, as Figures 2 - 4 shown, a reinforcing bar 11 is fixedly provided at the middle position in the width direction of the bottom frame 1, and the reinforcing bar 11 is fixedly connected to both the first channel steel 21 and the second channel steel 31.

[0053] In the above embodiments, the reinforcing bar 11 provided on the bottom frame 1 is composed of three parts. One section is located between the first channel steel 21 and the adjacent side of the bottom frame 1 and is fixedly connected to them. Another section is located between the first channel steel 21 and the second channel steel 31 and is fixedly connected to both the first channel steel 21 and the second channel steel 31. The last section is located between the second channel steel 31 and the adjacent side of the bottom frame 1 and is fixedly connected to them. By providing such a reinforcing bar 11 in the bottom frame 1, the integrity and overall strength of the bottom frame 1, the first channel steel 21, and the second channel steel 31 can be better, and deformation can be prevented when bearing the weight of multiple high-voltage bushing bodies 4.

[0054] Furthermore, as Figure 1 and Figure 2 shown, a plurality of metal ribs 12 are provided on the outer side of each closed iron plate 6 on the protection frame 5.

[0055] In the above embodiments, a plurality of metal ribs 12 are provided on the outer side of each closed iron plate 6 on the protection frame 5, which can improve the strength of the entire protection frame 5. When other packing boxes need to be stacked on the protection frame 5 during transportation, the protection frame 5 can also stably support them.

[0056] The implementation principle of this embodiment is as follows: When it is necessary to package the high-voltage bushing before transportation, the workers of the enterprise first place a plurality of prepared high-voltage bushing bodies 4 on the first groove 23 of the first wooden pallet 22 and the second groove 33 of the second wooden pallet 32 in sequence by using tools. Then, the first portal-shaped limiting frame 24 and the second portal-shaped limiting frame 34 are respectively installed on the first channel steel 21 and the second channel steel 31. Since the installation methods of the first portal-shaped limiting frame 24 and the second portal-shaped limiting frame 34 are the same, only the assembly method of the first portal-shaped limiting frame 24 is taken as an example here. The first portal-shaped limiting frame 24 is composed of two vertical rods and a horizontal rod. First, the two vertical rods are respectively abutted against the mutually remote sides of the upper end head rods of the two high-voltage bushing bodies 4 located on both sides in the width direction of the bottom frame 1. Then, the two vertical rods and the first channel steel 21 are fixedly connected by bolts and nuts. The horizontal rod is clamped on the upper side of the head rods at the top of the plurality of high-voltage bushing bodies 4, and a buffer cushion 7 is placed between the horizontal cross bar and the top of the high-voltage bushing body 4. Then, the two ends of the horizontal rod are respectively fixedly connected with the upper ends of the two vertical rods by bolts and nuts. At this time, the first portal-shaped limiting frame 24 composed of the horizontal rod and the vertical rods can simultaneously limit and fix the plurality of high-voltage bushing bodies 4. After fixing the plurality of high-voltage bushing bodies 4, the protection frame 5 equipped with the closed iron plate 6 is covered outside the plurality of high-voltage bushing bodies 4 and fixedly connected with the bottom frame 1, and thus the packaging work of the plurality of main high-voltage bushing bodies 4 can be completed.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
