[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please refer to Figures 1-4 This utility model provides a transformer winding coil storage and transfer vehicle, including a transport frame 1 and a hand-pulling assembly 2. The transport frame 1 includes a transport platform 11, two support legs 12 and two pulley legs 13. The two support legs 12 and the two pulley legs 13 are all disposed at the bottom of the transport platform 11. The two support legs 12 are respectively located at the front end near the front end of the transport platform 11, and the two pulley legs 13 are respectively located at the rear end near the rear end of the transport platform 11.

[0029] The hand-pulling assembly 2 includes a hinge base 21, a rotating shaft 22, a control rod 23, and a steering wheel 24. The hinge base 21 is installed at the front end of the transport platform 11. Both ends of the rotating shaft 22 are rotatably installed on the hinge base 21, and the rotating shaft 22 is arranged in the left-right direction. The side wall of the rotating shaft 22 is provided with a connecting plate 25, and the connecting plate 25 is provided with mounting holes. The lower end of the control rod 23 is rotatably installed in the mounting hole near the lower end, and the steering wheel 24 is installed at the lower end of the control rod 23.

[0030] The length from the connection point of the connecting plate 25 and the control rod 23 to the lowest point of the steering wheel 24 is greater than the sum of the heights of the transport platform 11 and the support frame 12.

[0031] The transformer winding coil storage trolley includes a fixed support state and a movable state. In the fixed support state, two support legs 12 and two pulley legs 13 support the transport platform 11. The friction between the support legs 12 and the ground is sufficient to fix the entire transformer winding coil storage trolley, serving a restraining and positioning function. After the transformer winding coil is wound, it can be placed on the transport platform 11. At this time, because the length from the connection point of the connecting plate 25 and the control rod 23 to the lowest point of the steering wheel 24 is greater than the sum of the heights of the transport platform 11 and the support legs 12, the control rod 23 tilts forward or backward.

[0032] When in motion, because the length from the connection point of the connecting plate 25 and the control rod 23 to the lowest point of the steering wheel 24 is greater than the sum of the heights of the transport platform 11 and the support frame 12, the front end of the transport platform 11 is lifted using the lever principle through the cooperation of the hinge seat 21, the rotating shaft 22, the control rod 23, and the steering wheel 24. At this time, the support frame 12 is suspended in the air, while the pulley frame 13 and the steering wheel 24 support the ground. Since the pulley frame 13 is equipped with a directional wheel 132, the workers can move the transformer winding coil storage cart to the required location as needed through the cooperation of the pulley frame 13 and the steering wheel 24. When the cart reaches its destination, the control rod 23 can be tilted forward or backward to make the support frame 12 touch the ground, thus fixing the position.

[0033] In addition, the lower end of the control lever 23 is rotatably mounted in the mounting hole, so that the steering wheel 24 located at the lower end of the control lever 23 can rotate about the central axis of the control lever 23. The steering wheel 24 can be rotated by controlling the control lever 23, thereby achieving the purpose of turning the transformer winding coil storage vehicle.

[0034] The transformer winding coil storage and transfer trolley combines the transport frame 1 and the hand-pulling assembly 2, which facilitates the handling of transformer winding coils. It has a simple structure, small footprint, saves time and labor, and greatly improves handling efficiency. When mass-producing transformer winding coils, it can be used in conjunction with a crane to handle the transformer winding coils without having to wait in line for the crane to handle them.

[0035] Optionally, in some specific embodiments of this utility model, the transport platform 11 includes a frame 111, a fixed plate 112, a movable plate 113, and a drive device 114; the support legs 12 and the pulley legs 13 are both disposed at the bottom of the frame 111; the fixed plate 112 is fixed to the top of the frame 111, and the fixed plate 112 has a rearward-facing receiving notch 115, the shape and size of which are adapted to the movable plate 113; the movable plate 113 has a rotating shaft 22 on both sides of its rear end, and the side wall of the opening of the receiving notch 115 has a mounting hole, and the rotating shaft 22 is rotatably mounted in the mounting hole on the corresponding side;

[0036] The support frame 12 is provided with a fixed platform 121. The driving end of the driving device 114 is hinged to the fixed platform 121, and the fixed end of the driving device 114 is hinged to the bottom of the movable plate 113. The driving device 114 is located near the front end of the movable plate 113. The driving device 114 is used to drive the movable plate 113 to rotate about the line connecting the central axes of the two rotating shafts 22.

[0037] In a specific embodiment of this utility model, the driving device 114 can be a pneumatic cylinder or a hydraulic cylinder. The driving device 114 can drive the movable plate 113 to rotate around the line connecting the central axes of the two rotating shafts 22, causing the movable plate 113 to tilt backward. With the above structure, it is convenient for workers to move the lightweight and small transformer winding coils from the transport platform 11 to the forklift, reducing labor intensity and improving handling efficiency.

[0038] In one specific embodiment of this utility model, driving devices 114 are hinged to both sides of the front end of the movable plate 113, and each of the two support legs 12 is provided with a fixed platform 121. The driving end of the driving device 114 is hinged to the fixed platform 121 on the corresponding side, and the two driving devices 114 move synchronously. With the above structure, the movable plate 113 is supported by the two driving devices 114, making the tilting process of the movable plate 113 more stable and avoiding the problem of deformation of the movable plate 113 or overturning of the transformer winding coil due to the placement position of the transformer winding coil deviating from the central axis of the movable plate 113. In another embodiment, one end of the fixed platform 121 is connected to one side of the support leg 12, and the other end of the fixed platform 121 is connected to the other side of the support leg 12.

[0039] Optionally, the transport platform 11 further includes a baffle 116, and the fixing plate 112 is provided with plug-in blocks 101 on both sides of the accommodating notch 115. The plug-in blocks 101 are located near the rear end of the fixing plate 112. The bottom of the baffle 116 is provided with plug-in holes that are adapted to the position and shape of the plug-in blocks 101, and the plug-in blocks 101 are inserted into the plug-in holes.

[0040] When the transformer winding coil storage trolley is in a moving state, the control lever 23 and the steering wheel 24 lift the front end of the transport platform 11. During the entire movement, the transport platform 11 remains tilted backward. Therefore, before the transformer winding coil storage trolley changes from a fixed support state to a moving state, the baffle 116 can be inserted into the rear end of the transport platform 11 to block it and prevent the transformer winding coil from falling off the transport platform 11 when changing from a fixed support state to a moving state or during the movement, thereby avoiding damage to the transformer winding coil.

[0041] Preferably, the tilt angle of the movable plate 113 is 10 to 30°.

[0042] In practical applications, the tilt angle of the movable plate 113 is 10 to 30°. When the tilt angle of the movable plate 113 is less than 10°, it cannot play a role in assisting the handling. When the tilt angle of the movable plate 113 is less than 30°, due to the large mass of the transformer winding coil, it is difficult to control the angle during handling, which increases the workload and easily leads to the transformer winding coil falling off the transport platform 11.

[0043] Specifically, the control lever 23 includes a connecting rod 231 and a transmission rod 232. The middle part of the connecting rod 231 is rotatably mounted in the mounting hole. The steering wheel 24 is mounted on the bottom of the connecting rod 231. The top of the connecting rod 231 is detachably connected to the bottom of the transmission rod 232. The top of the transmission rod 232 is provided with a handle 233.

[0044] The connecting rod 231 and the transmission rod 232 are coaxially arranged. The transmission rod 232 drives the connecting rod 231 and the steering wheel 24 to rotate around their own axis, thus achieving the purpose of turning the transformer winding coil storage cart. The handle 233 provides a point of force application for easy control, enabling movement, turning, and the transformation of the transformer winding coil storage cart from a fixed support state to a moving state. The above structure is simple and easy to perform operations such as movement, turning, and state transformation, improving operational comfort. The connecting rod 231 and the transmission rod 232 are detachably connected, and the appropriate length of the transmission rod 232 can be selected according to the actual situation, making the process of transforming the transformer winding coil storage cart from a fixed support state to a moving state more effortless.

[0045] Specifically, the support legs 12 and the pulley legs 13 are of the same length. The fact that the support legs 12 and the pulley legs 13 are of the same length ensures that the transport platform 11 remains horizontal when the transformer winding coil storage trolley is in a fixed support state, preventing the transformer winding coil from slipping off the transport platform 11 due to tilting.

[0046] Specifically, the pulley bracket 13 includes a support leg 131 and a directional wheel 132. The upper end of the support leg 131 is connected to the bottom of the transport platform 11, and the lower end of the support leg 131 is provided with a directional wheel mounting seat 133. The directional wheel 132 is rotatably mounted on the directional wheel mounting seat 133.

[0047] The directional wheel 132 is mounted on the directional wheel mounting base 133. The rotation axis of the directional wheel 132 is set in the left-right direction, so that the directional wheel 132 can rotate in the front-back direction. With the above structure, the directional wheel 132 and the transport platform 11 are connected by the support foot 131. The support foot 131 of a suitable length can be selected to ensure that the lengths of the support leg 12 and the pulley leg 13 are consistent.

[0048] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
