Technical Field
[0001] The utility model relates to the field of coils, in particular to the technical field of transformer coil production, and specifically refers to a hydraulic trolley for coil transfer. Background Art
[0002] Transformer coils are generally classified into two types: layer and pancake. Layer coils are those where the turns are arranged in layers along the axial direction and wound continuously. Each layer is cylindrical, ensuring good mechanical strength, resistance to deformation, and ease of winding. Coils consisting of two layers are called double-layer cylindrical coils; coils consisting of multiple layers are called multi-layer cylindrical coils.
[0003] The transformer coil consists of an iron core, as well as copper foil and copper wire wrapped around the iron core. After the copper foil is wound, the semi-finished coil needs to be transferred and then the copper wire is wound. Therefore, a trolley that can load and unload materials and can be transported is required. Utility Model Content

[0006] When the new type of device is in use, the vehicle body is moved to the bottom of the coil, and then the manual pump is driven to extend the hydraulic cylinder, so that the support platform supports the coil, and then the trolley is pulled to drive the coil to be transferred. Through the setting of the crank arm, the operator is located on the side of the coil, which makes it convenient for the staff to observe the rising of the support platform. At the same time, the staff presses the manual pump to extend the hydraulic cylinder, so that the rise of the support platform can be manually controlled, thereby enhancing the stability of the rise of the support platform.

[0008] In this preferred solution, the support block is tilted toward the middle by setting two auxiliary plates, and the two support blocks are arranged in a V shape, thereby facilitating the support of the coil. The support strength of the bottom plate is enhanced by setting the support blocks.
[0009] Preferably, a groove is provided on the side surface of the support block, and a first bolt for bolt-connecting the support block and the support plate is provided in the groove.
[0010] When using this preferred solution, the first bolt is placed into the groove, and then the support block and the support plate are threadedly connected.
[0011] Preferably, the support plate is provided with a plurality of threaded holes arranged along the axial direction of the coil.
[0012] This preferred solution facilitates adjustment of the position of the support block on the support plate by providing a plurality of threaded holes.

The cross beams are bolted to fixed seats on both sides of the hydraulic cylinder. A fixing rod passing through the fixed seat is fixed to the hydraulic cylinder body, and the fixing rod is fixed to the fixed seat.
[0017] This preferred solution facilitates the assembly of the vehicle body through the provision of the crossbeam and the longitudinal beam, and facilitates the installation of the hydraulic cylinder on the vehicle body through the cooperation of the fixing rod and the fixing seat.
[0018] Preferably, an intermediate plate located between the crossbeam and the support platform is fixed to the crossbeam, and a through-hole is provided on the intermediate plate for the sleeve to pass through. A ring with a diameter larger than the through-hole and supported on the top surface of the intermediate plate is also fixed to the sleeve.
[0019] In this preferred solution, the sleeve is supported by the collar, thereby facilitating the assembly and disassembly of the sleeve on the middle plate.
[0020] The beneficial effects of the present invention are as follows: the vehicle body is moved to the bottom of the coil, and then the manual pump is driven to extend the hydraulic cylinder so that the support platform supports the coil, and then the trolley is pulled to drive the coil to be transferred. Through the setting of the crank arm, the operator is located on the side of the coil, which is convenient for the staff to observe the rise of the support platform. At the same time, the staff presses the setting of the manual pump to extend the hydraulic cylinder, so that the rise of the support platform can be manually controlled, and the stability of the rise of the support platform is enhanced; through the setting of the two auxiliary plates, the support block is tilted to the middle, and the two support blocks are arranged in a V shape, which is convenient for supporting the coil.
