Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative work belong to the range of the utility model protection.

[0024] Embodiment one, by Figure 1 The utility model relates to a kind of hoisting devices for power transformer installation, including hoist plate 1, its hoist plate 1 is equipped with clamping mechanism 2 and limiting mechanism 3.

[0025] Specifically, by Figure 2-4It is given that the clamping mechanism 2 includes two guide round rods 201 symmetrically fixed to the bottom of the hanging plate 1, and a guide plate 206 is movably sleeved between the two guide round rods 201. A clamping plate 205 is provided on the top of the guide plate 206. The bottom of the clamping plate 205 is fixedly connected to the vertical plate 204. The bottom of the vertical plate 204 passes through the guide plate 206 and is fixedly connected to the bottom plate 203, and the vertical plate 204 is movably connected to the guide plate 206. The top of the hanging plate 1 is fixedly connected to the abutment plate 6, and the abutment plate 6 and the clamping plate 205 are arranged parallel to each other. A accommodating groove 5 is provided on the hanging plate 1, and the clamping plate 205 passes through the accommodating groove 5. The top surface of the clamping plate 205 is flush with the top surface of the hanging plate 1. The hanging plate 1 is provided with an avoidance groove 4. The groove 4 matches the vertical plate 204. The bottom of the hanging plate 1 is fixedly connected to a positioning plate 207 located between the two guide round rods 201. A plurality of jacks 202 are equidistantly provided on the outer side of the positioning plate 207. The outer side of the bottom plate 203 is rotatably connected to a screw rod 2012. The end of the screw rod 2012 away from the bottom plate 203 is fixedly connected to a turntable 2010. The outer side of the screw rod 2012 is threadedly sleeved with a screw sleeve 2011. The outer side of the screw sleeve 2011 is fixedly connected to a slide plate 209. The outer side of the slide plate 209 is fixedly connected to an insertion rod 208. The outer diameter of the insertion rod 208 is equal to the inner diameter of the insertion hole 202. A slide groove 2013 is provided on the outer side of the bottom plate 203. The slide plate 209 is slidably connected to the slide groove 2013.

[0026] When the lifting plate 203 is in the state of use, the power transformer is first placed on the top of the lifting plate 1 and abutted against the abutment plate 6, and then the bottom plate 203 is pushed upward, and the clamping plate 205 is driven upward by the vertical plate 204, so that the clamping plate 205 is moved out of the accommodating groove 5 until the bottom plate 203 abuts against the guide plate 206, and then the bottom plate 203 is moved horizontally and sleeved on the outer side of the positioning plate 207, and at the same time, the guide plate 206 slides along the two guide round rods 201 until the clamping plate 205 abuts against the power transformer, and then the turntable 2010 is rotated to drive the screw 2012 to rotate, and the slide plate 209 is driven by the screw sleeve 2011 to slide along the slide groove 2013, and drive the insertion rod 208 to move until it is inserted into the corresponding socket 202, fixing the bottom plate 203 and the positioning plate 207, and fixing the position of the clamping plate 205.

[0028] When in use, first rotate the hand wheel 302 to drive the bidirectional screw rod 306 to rotate. Since the two limiting round rods 303 pass through the lifting frame 301 and are movably connected to the lifting frame 301, they guide the two movable plates 305, so that the two movable plates 305 move horizontally and drive the two limiting plates 304 to move closer to each other to limit the power transformer, thereby further improving the stability of the power transformer during lifting.
