Description

Technical Field

[0001] The utility model belongs to the technical field of transformer iron core processing, and in particular relates to a transformer iron core transportation device. Background Art

[0002] In the prior art, the iron core of the dry-type transformer is transported in a box to reduce damage from bumps and corrosion from moisture. When the iron core encounters bumpy roads or is transported, it is easy for the iron core to collide and scratch with the box. The transformer iron core is large and heavy, so how to prevent the iron core from bumping inside the box when transporting the box containing the iron core is also a problem.

[0003] In order to ensure the performance and quality of the iron core, a transformer core transportation device is needed to reduce the fixation of the iron core and avoid bumps and damage during transportation. Utility Model Content

[0004] In view of the problem that the iron core in the prior art is subject to bumps and scratches during transportation, the utility model provides a transformer iron core transportation device, in which the transportation box is changed into a split type to facilitate the packing of the iron core. An elastic limiting structure is provided on the back plate of the transportation box, which can elastically limit the iron core in the horizontal direction to prevent the iron core from tipping over and bumping.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The transformer core transport device is characterized by: comprising:

[0007] The box body is a split structure, including a lower box body and an upper box body, the lower box body includes a bottom surface, a back plate and two side plates, the upper box body includes a top surface and a front surface, and the upper box body and the lower box body are connected by bolts;

[0008] The elastic limiting structure is fixedly mounted on the back plate, and four groups are provided. Each group of the elastic limiting structure includes two limiting plates and an elastic member in the middle. The back plate is provided with a horizontal track. A slider is provided on a side of the limiting plate close to the track. The limiting plate can translate along the horizontal track with the help of the slider.

[0009] The elastic anti-collision plate is fixedly mounted on the back plate by means of a spring, and each elastic anti-collision plate is arranged between each adjacent group of elastic limiting structures.

[0010] The box adopts a split structure, which is convenient for the iron core to be placed in, whether it is hoisted or placed horizontally; each set of elastic limiting structures is inserted between the iron cores and limits the iron cores from both ends to prevent the iron cores from shaking left and right and bumping against each other. The limiting plate can clamp the coils or silicon steel sheets to prevent the silicon steel sheets from bumping against each other and generating noise during transportation; whether the iron core has a coil or not, it is subject to the static friction of the limiting plate during the process of being clamped by the elastic limiting structure, and is not easy to slide back and forth. The iron core is likely to shake back and forth only when the transport vehicle brakes suddenly or other inertial forces occur. The elastic anti-collision plate supports and limits the iron core from the back of the iron core to prevent the iron core from bumping against the back plate and the horizontal track.

[0011] Preferably, the horizontal rails are provided with one high and one low, and the elastic anti-collision plate and the spring are provided between the upper and lower horizontal rails.

[0012] The horizontal rails are set at different heights, and the limit plates are fixed from the upper and lower ends, so that the limit plates can be evenly stressed and the chance of damage can be reduced.

[0013] Preferably, the minimum travel of the spring exceeds the horizontal track by 3 cm.

[0014] The spring is higher than the horizontal track, so that the elastic anti-collision plate can still be higher than the horizontal track when it is squeezed to the limit, thereby further avoiding collision between the iron core and the horizontal track or the back plate.

[0015] Preferably, the elastic anti-collision plate is an arc-shaped or flat plate structure.

[0016] The arc-shaped structure is more suitable for the iron core with coils, and the flat structure is suitable for the iron core without coils.

[0017] Preferably, the limiting plate and the elastic anti-collision plate are both made of elastic rubber.

[0018] The elastic rubber has a buffering effect when in contact with the iron core and is not likely to damage the silicon steel sheet of the iron core.

[0019] Preferably, the elastic limiting structure also includes a rubber bellows that seals and connects the two limiting plates.

[0020] The rubber bellows mainly plays a sealing role to prevent dust or other debris from getting stuck in the elastic parts.

[0021] Preferably, an elastic barrier layer is further provided between the front surface of the upper box body and the iron core, and the elastic layer is foam, rubber or multi-layer cardboard.

[0022] The elastic barrier layer can separate the iron core from the front side of the upper box body, thereby preventing the iron core from tilting and colliding with the upper box body.

[0023] Preferably, the outer surfaces of the side panels of the lower box body are provided with fixing seats and connecting rings, a rope is fixedly connected to the fixing seat, and the other end of the rope is bound and matched with the connecting ring.

[0024] The box can be fixed on the transport vehicle or connected to other boxes by means of ropes.

[0025] The beneficial effects of the utility model are as follows: the iron core can be clamped by passing through the middle gap of the iron core with the help of the elastic limiting structure, and then clamped inward from both ends of the iron core. During the normal driving of the transport vehicle, the iron core can be prevented from shaking and causing bumps. During the transportation process, the iron core is clamped by the elastic limiting structure and is not prone to collision, which facilitates transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The elastic limiting structure 3 is fixedly mounted on the back plate 102, and four groups are provided. Each group of the elastic limiting structure 3 includes two limiting plates 301 and an elastic member 302 in the middle. The back plate 102 is provided with a horizontal track 4. A slider 303 is provided on a side of the limiting plate 301 close to the track. The limiting plate 301 can translate along the horizontal track 4 with the help of the slider 303.

[0038] The elastic anti-collision plate 5 is fixedly mounted on the back plate 102 by means of a spring 501 , and each elastic anti-collision plate 5 is arranged between each adjacent group of elastic limiting structures 3 .

[0039] like Figure 1 , 2 As shown in FIG. 4 , the horizontal rails 4 are provided with one high and one low, and the elastic anti-collision plate 5 and the spring 501 are provided between the upper and lower horizontal rails 4 .

[0040] In order to reduce collision, the minimum travel of the spring 501 beyond the horizontal track 4 is 3 cm.

[0041] In order to adapt to different iron cores, the elastic anti-collision plate 5 is an arc-shaped or flat plate structure.

[0042] In order to avoid damage to the iron core, the limiting plate 301 and the elastic anti-collision plate 5 are made of elastic rubber.

[0043] like Figure 1 , 2 As shown in FIG. 5 , the elastic limiting structure 3 further includes a rubber bellows 304 sealingly connecting the two limiting plates 301 .

[0044] like Figure 1 and 2 As shown, an elastic barrier layer 6 is further provided between the front surface of the upper box body 2 and the iron core, and the elastic barrier layer 6 is foam, rubber or multi-layer cardboard.

[0045] like Figure 1 , 2As shown in FIG. 3 , the outer surfaces of the side plates of the lower box body 1 are provided with a fixing seat 7 and a connecting ring 701 , and a rope 702 is fixedly connected to the fixing seat 7 , and the other end of the rope 702 is bound and matched with the connecting ring 701 .

[0046] Working principle: The present invention sets an elastic limiting structure 3 through the middle gap of the iron core, and then clamps it inward from both ends of the iron core. The elastic member 302 inside the elastic limiting structure 3 can clamp the iron core through the outward tension, so that the shaking of the iron core can be reduced during the handling and transportation of the iron core after it is loaded into the box. The coil or silicon steel sheet of the iron core contacts the limiting plate 301 to avoid collision with the box. In addition, an elastic anti-collision plate 5 is provided. If the inertia force is too large during the transportation of the iron core, The power of the iron core exceeds the static friction between the limit plate 301 and the iron core, and the iron core will contact the elastic anti-collision plate 5. The spring 501 absorbs the inertia force of the iron core, thereby reducing the shaking of the iron core and preventing the vibration of the internal silicon steel sheet caused by the shaking of the iron core. At the same time, the box adopts a split structure with the upper and lower boxes separated. Regardless of whether the iron core is hoisted or placed horizontally, the iron core can be easily placed in the box. The upper box 2 and the lower box 1 form a sealed structure, which can prevent moisture and dust from entering to corrode and damage the iron core.
