Description

Technical Field

[0001] This utility model belongs to the field of transformer manufacturing technology, specifically relating to an air cushion vehicle tray for ultra-high voltage reactors, used for the overall assembly and testing of ultra-high voltage reactors. Background Technology

[0002] Ultra-high voltage reactors are characterized by their large weight and high noise during testing. General transportation equipment cannot meet the loading requirements. During the final assembly and testing of ultra-high voltage reactors, special transformer air cushion vehicle pallets are required for storage and transportation.

[0003] Currently used transformer air cushion vehicle trays have technical problems such as thin panels and light weight, and do not have effective vibration reduction and noise reduction functions. During the vibration and noise test of UHV reactors, the air cushion vehicle tray is prone to vibrate together with the UHV reactor, affecting the vibration and noise test results of the UHV reactor. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides an air cushion vehicle pallet for ultra-high voltage reactors. The technical solution adopted by this utility model is as follows:

[0005] A type of air cushion vehicle pallet for ultra-high voltage reactors includes a rectangular panel. A rubber sheet is fixedly installed on the upper surface of the panel. Several parallel steel beams are uniformly welded along the width direction on the lower surface of the panel. A steel beam lower end plate is welded to the lower surface of the steel beam lower end plate. Several parallel steel legs are welded along the length direction of the lower surface of the steel beam lower end plate. Laminated wood is fixedly installed on the lower surface of the steel legs. A second rubber sheet is fixedly installed on the lower surface of the laminated wood. Several cavities are formed at the steel beams and steel legs respectively. River sand is filled into the cavities. End plates are welded to the four sides of the steel beams and steel legs.

[0006] Preferably, several countersunk bolt holes are machined along the edge of the panel along its length, and countersunk holes corresponding to the countersunk bolt holes are machined along the edge of the rubber plate. The countersunk bolts pass through the countersunk holes and are screwed into the countersunk bolt holes.

[0007] Preferably, several plug welding holes are made on the lower end plate of the steel beam, corresponding to the position of the steel beam.

[0008] Preferably, several screw holes are made on the lower surface of the steel leg, and the laminated wood is fixedly installed on the lower part of the steel leg by countersunk screws, and the rubber plate is fixedly bonded to the lower part of the laminated wood by adhesive.

[0009] Preferably, the steel legs and steel beams are made of I-beams.

[0010] Preferably, several parallel vertical reinforcing irons are welded to the two outer sides of the steel legs.

[0011] Preferably, several hanging supports are symmetrically arranged along the lower edge of the bottom plate of the steel beam.

[0012] Preferably, the panel is made of low alloy steel plate, the lower end plate of the steel beam is made of low alloy steel plate, the end plate is made of low alloy steel plate, and the hanging bracket is made of low alloy steel plate.

[0013] Preferably, the length of the auxiliary sound insulation mechanism matches the length of the steel crossbeam, the shape of the auxiliary sound insulation mechanism matches the side structure of the air cushion vehicle pallet in the width direction, the auxiliary sound insulation mechanism is assembled on both sides of the air cushion vehicle pallet in the width direction by interference fit, and the auxiliary sound insulation mechanism is made of polyester fiber.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a vibration-reducing rubber plate on the upper surface of the panel, the rubber plate has good elasticity. When the vibration generated during the reactor vibration and noise test passes through the rubber plate, the rubber plate will absorb some of the energy, thereby reducing the vibration transmitted to the air cushion vehicle pallet.

[0016] 2. By filling the closed cavities at the steel beams and steel legs with river sand, which has good elasticity and friction, the vibration generated by the reactor test will absorb some of the energy when it passes through the sand, thereby reducing the vibration transmitted to the air cushion vehicle pallet.

[0017] 3. This utility model has high support strength and reasonable structural design, which can reduce the generation and propagation of noise during the testing of ultra-high voltage reactors. Attached Figure Description

Detailed Implementation

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example 1

[0028] like Figure 1-6 As shown, an air cushion vehicle pallet for an ultra-high voltage reactor includes a rectangular panel 1 made of low-alloy steel plate. Several countersunk bolt holes 9 are machined along the longitudinal edge of the panel 1. A countersunk hole corresponding to the countersunk bolt holes 9 is machined along the edge of a rubber sheet 2. Countersunk bolts are screwed into the countersunk bolt holes 9 through the countersunk holes to fix the rubber sheet 2 onto the upper surface of the panel 1.

[0029] Several parallel steel beams 16 are evenly distributed on the lower surface of panel 1 in the width direction by welding. A lower steel beam end plate 14 is welded below each steel beam 16. The lower steel beam end plate 14 is made of low-alloy steel plate, and several plug-weld holes 10 are formed on the lower steel beam end plate 14 corresponding to the positions of the steel beams 16. The plug-weld holes 10 facilitate the secure welding of the lower steel beam end plate 14 to the steel beams 16. The two ends of the steel beams 16 are sealed by welding with steel beam side end plates 3 in the length direction, and the two outer sides of the steel beams 16 are sealed by welding with steel beam side end plates 8 in the width direction. After sealing with the end plates, several steel beam cavities 15 in the width direction are formed between adjacent steel beams 16 and between the outermost steel beam 16 and steel beam side end plate 8. The steel beam side end plates 8 and 3 are made of low-alloy steel plate.

[0030] Two parallel steel legs 12 are welded along the longitudinal edge of the lower surface of the steel beam's lower endplate 14. The two ends of each steel leg 12 are sealed by welding with a steel leg side endplate 4 in the width direction, and the two outer sides of each steel leg 12 are sealed by welding with a steel leg side endplate 5 in the longitudinal direction. After sealing with the endplates, three longitudinal steel leg cavities 13 are formed between adjacent steel legs 12 and between the outer sides of each steel leg 12 and the steel leg side endplate 5. The steel leg side endplates 4 and 5 are made of low-alloy steel.

[0031] Several screw holes are made on the lower surface of the steel support leg 12. Laminated wood 11, which matches the size of the steel support leg 12, is fixedly installed on the lower part of the steel support leg 12 with countersunk screws. Rubber plate 2 6 is fixedly glued to the lower part of the laminated wood 11 with strong adhesive. The laminated wood 11 and rubber plate 2 6, in addition to reducing vibration and noise, also protect the ground and prevent damage to the ground during the transfer of the air cushion vehicle pallet.

[0032] Furthermore, the steel legs 12 and steel beams 16 are preferably made of I-beams, which not only have high mechanical strength but are also easy to weld and install. At the same time, they can reasonably form several steel leg cavities 13 and steel beam cavities 15 for containing river sand.

[0033] Furthermore, in order to improve the mechanical strength of the steel leg 12, several parallel vertical reinforcing irons 17 are welded on both outer sides of the steel leg 12. The reinforcing irons 17 divide the original steel leg cavity 13 on both sides into several steel leg cavity 18.

[0034] The steel beam cavity 15, the steel leg cavity 13, and the steel leg cavity 18 are all filled with river sand.

[0035] Furthermore, to facilitate the lifting and transfer of the air cushion vehicle pallet, several lifting hooks 7 are symmetrically arranged along the lower edge of the steel crossbeam's lower end plate 14. The lifting hooks 7 are made of low-alloy steel plate. Correspondingly, positions for welding the lifting hooks 7 are left at the top of the steel crossbeam 16, and notches for the lifting ropes to pass through are made on the panel 1 and the rubber plate 2. Example 2

[0036] To further improve the sound insulation and noise reduction effect, Embodiment 2 of this utility model adds an auxiliary sound insulation mechanism 19 based on Embodiment 1. For example... Figure 7As shown, the length of the auxiliary sound insulation mechanism 19 matches the length of the steel crossbeam 16, and the shape of the auxiliary sound insulation mechanism 19 matches the side structure of the air cushion vehicle pallet in the width direction. The auxiliary sound insulation mechanism 19 is assembled on both sides of the air cushion vehicle pallet in the width direction by interference fit, and the auxiliary sound insulation mechanism 19 is made of polyester fiber. During the vibration and noise test of the ultra-high voltage reactor, the auxiliary sound insulation mechanism 19 can be inserted into both sides of the air cushion vehicle pallet in the width direction without fixing, making disassembly and assembly very convenient. The auxiliary sound insulation mechanism 19 can physically isolate the propagation of vibration noise from the air cushion vehicle pallet.

[0037] In this embodiment of the utility model, all technical features not described in detail are existing technologies or conventional technical means, and will not be repeated here.

[0038] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Those skilled in the art should understand that any person skilled in the art can modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this utility model; and these modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be covered within the protection scope of this utility model.
