A swinging rod is hinged to the support. A clamping plate is hinged to the other end of the swinging rod. A threaded hole penetrating through the inside and outside is formed in the lower end of the support plate, and a fixing bolt is installed in the threaded hole. An antiskid pad is installed on the inner end head of the fixing bolt.
[0008] The middle part of the swing rod is connected with a lifting rope, the lifting rope passes through a fixed pulley, and the other end of the lifting rope is connected to the lower end of the lifting column.
[0009] Preferably, a lifting ring is connected to the top end of the lifting column, facilitating cooperation with a lifting hook.
[0010] Preferably, the middle segment of the lifting column is a threaded column, and a double nut is installed, which can prevent the lifting device from damaging the transformer due to excessive pulling of the transformer.
[0011] Preferably, a first spring is installed inside the hinge between the clamping plate and the swing rod, so that the clamping plate is in a vertical state when the device is not in use, facilitating direct clamping of the transformer when in use.
[0012] Preferably, the inner surface of the clamping plate is covered with a rubber non-slip surface to prevent the transformer from slipping when lifting.
[0013] Preferably, the fixed bolt and the non-slip pad are connected by a second spring, facilitating easier adjustment of the fixed bolt when the transformer is initially fixed.
[0014] Preferably, the non-slip pad is made of rubber to avoid damaging the transformer.
