Description

Technical Field

[0002] A transformer is an electrical device used to change the voltage and current level of alternating current. Its main function is to transfer electrical energy from one circuit to another, while changing the voltage level of the power supply or the power supply load, to achieve the purpose of power transmission and distribution.

[0003] In the related art, before using the transformer, it is necessary to transport the transformer to a designated location by a transfer device. During the transportation process using the transfer device, the position of the transformer must be fixed to prevent the transformer from being damaged due to frequent shaking.

[0004] However, in actual use, due to the structural limitations of the transfer device, it is not convenient to position and clamp the transformer.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-Figure 5 As shown, the transformer transport device provided in the embodiment of the present application includes a load-bearing chassis 100, a positioning rod 300, a plurality of clamping plates 400, and a walking assembly 600, wherein the load-bearing chassis 100 is a load-bearing mechanism of the transport device, and the transformer can be placed and fixed on the load-bearing chassis 100 of the transport device to realize the transport operation. A traction frame 200 is also provided on the side of the load-bearing chassis 100. In actual use, the traction frame 200 of the transport device can be connected to a power device, so as to realize the purpose of driving the transport device to transport the transformer.

[0035] The positioning rod 300 is fixedly arranged on the outer surface of the side wall of the load-bearing chassis 100. Specifically, two positioning rods 300 are arranged on the outer surface of the side wall of the load-bearing chassis 100, and each positioning rod 300 extends along the length direction of the load-bearing chassis 100. In this embodiment, the positioning rod 300 is an elongated structure with a certain length and a circular cross-section. There is a gap between each positioning rod 300 and the outer surface of the side wall of the load-bearing chassis 100, that is, the positioning rod 300 is not in close contact with the outer surface of the side wall of the load-bearing chassis 100.

[0036] Preferably, a fixed connecting rod 900 is provided at the center line along the length direction of the positioning rod 300. Figure 4 As shown, the positioning rod 300 is welded to the supporting chassis 100 through the fixing connecting rod 900. Of course, the two may also be fixedly connected in other structures, which are not limited in this embodiment.

[0037] like Figure 1 and Figure 2 As shown in FIG. 1 , a plurality of clamping plates 400 are slidably disposed on the positioning rod 300, and each clamping plate 400 can also rotate along the positioning rod 300. In other words, the clamping plates 400 can move along the length direction of the positioning rod 300 and can also rotate relative to the positioning rod 300. The clamping plates 400 can move to the end positions of the length direction of the two side walls of the supporting chassis 100, such as Figure 3 In addition, a plurality of balls 500 are disposed on the outer wall surface of each clamping plate 400 , and the balls 500 can rotate relative to the clamping plate 400 at a fixed point.

[0038] Preferably, each clamping plate 400 may include a movable end 410 and a clamping end 420 connected to the movable end 410 , the movable end 410 is sleeved on the positioning rod 300 , and the clamping end 420 is used to clamp and fix the transformer on the supporting chassis 100 .

[0039] Continue as Figure 1-Figure 3 As shown, the movable end 410 and the clamping end 420 can be an integrally formed structure, or can be a welded structure. The movable end 410 and the outer surface of the side wall of the supporting chassis 100 are parallel to each other, and the angle between the clamping end 420 and the movable end 410 is 120°. In this way, the clamping plate 400 can be easily moved on the positioning rod 300, and the transformer can be clamped and fixed to the maximum extent.

[0040] In this embodiment, the walking assembly 600 includes a walking bracket 700 and a walking wheel 800 connected to the walking bracket 700. The walking bracket 700 is fixedly arranged on the outer surface of the side wall of the load-bearing chassis 100, and the walking bracket 700 is located beside the positioning rod 300. There is a certain distance between the walking wheel 800 and the outer surface of the side wall of the load-bearing chassis 100, and the distance is adapted to the thickness of the clamping plate 400. When the clamping plate 400 moves between the walking wheel 800 and the load-bearing chassis 100, the walking wheel 800 realizes dynamic contact with the clamping plate 400 through the ball 500 to ensure that the clamping plate 400 can always be in a clamping state.

[0041] like Figure 3 As shown, in the transformer transport device provided in the embodiment of the present application, the transformer to be transported is placed on the load-bearing chassis 100, and then the plurality of clamping plates 400 are respectively slid to the two end positions in the length direction of the load-bearing chassis 100 along the direction of the positioning rod 300, and are located between the load-bearing chassis 100 and the running wheels 800. At this time, a power device can be connected to the traction frame 200 of the transport device so that the transport device can move by relying on the running assembly 600. When the transport device moves, the running wheels 800 will always contact the balls 500 on the outer wall of the clamping plate 400, so that the clamping plate 400 can always maintain a clamping state to ensure the stability of the transformer placed on the load-bearing chassis 100.

[0042] In some embodiments, Figure 5 The area of ​​the clamping end 420 of the clamping plate 400 is larger than the cross-sectional area of ​​the entire clamping plate 400, and the end surface of the clamping end 420 is also provided with anti-slip wear patterns 421. This enables the clamping plate 400 to further improve the clamping and fixing effect on the transformer, thereby preventing the transformer from shaking during transportation to the greatest extent.

[0043] In some embodiments, Figure 4As shown, the outer surface of the side wall of the load-bearing chassis 100 is provided with a limiting protrusion 110, and the limiting protrusion 110 is located near the position of the running wheel 800. In contrast, the clamping plate 400 is provided with a limiting groove 430 near the side wall of the load-bearing chassis 100. When the clamping plate 400 moves between the load-bearing chassis 100 and the running wheel 800, the limiting protrusion 110 of the load-bearing chassis 100 can slide into the limiting groove 430 of the clamping plate 400, so that the clamping plate 400 can move in a directional manner.
