Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown, a transformer hoisting device includes a frame 101. A slide rail 102 is provided inside the frame 101. An electric hoist 105 is slidably mounted on the outer surface of the slide rail 102. A slide frame 201 is provided at the upper end of the electric hoist 105. Multiple sliding plates 204 are slidably mounted inside the slide frame 201. Each of the multiple sliding plates 204 has a protective frame plate 205 that can be adjusted up and down at its lower end. A drive mechanism for moving the sliding plates 204 is provided inside the slide frame 201. Personnel can also manually drive two sliding plates 204 to move two sliding frame plates towards each other to limit the movement of the transformer during hoisting.

[0021] Hydraulic push rods 207 are provided at the lower end of each sliding plate 204. The two hydraulic push rods 207 are positioned correspondingly to each other. The telescopic ends of the two hydraulic push rods 207 are connected to the upper ends of the adjacent protective frame plates 205. Two guide posts 203 are slidably arranged inside each of the two sliding plates 204. The two adjacent guide posts 203 are connected to the upper ends of the adjacent protective frame plates 205. The guide posts 203 and the protective frame plates 205 are fixed together by welding.

[0022] likeFigure 2 , 3 As shown, the drive mechanism includes a bidirectional lead screw 206 rotatably mounted inside the slide frame 201 via bearings. Two sliding plates 204 are threadedly connected to the left and right corresponding ends of the bidirectional lead screw 206, respectively. A drive unit for driving the bidirectional lead screw 206 to rotate is provided on the left side of the slide frame 201. The drive unit includes a motor 202 located on the left side of the slide frame 201. The output shaft of the motor 202 is connected to the left end of the lead screw via a coupling.

[0023] like Figure 1 As shown, a controller 106 is provided on the lower front side of the frame 101. The electric hoist 105, hydraulic push rod 1 207, hydraulic push rod 2 301 and motor 202 are all electrically connected to the controller 106. The controller 106 can be a Siemens SIMATIC S7-1500+CPU.

[0024] By hooking the lifting hook on the electric hoist 105 onto the transformer to be hoisted, and then controlling the electric hoist 105 to start running via the controller 106, the transformer can be hoisted. Then, the electric hoist 105 can be moved under the restriction of the slide rail 102 by the controller 106.

[0025] When the transformer is hoisted by the electric hoist 105, the controller 106 controls the hydraulic push rod 207 to operate. The telescopic end can drive the protective frame plate 205 to move downward to a protective height that matches the transformer under the sliding restriction of the guide column 203. Then, the controller 106 controls the motor 202 to operate, and the output shaft drives the bidirectional screw 206 to rotate. Due to the guiding and limiting effect of the slide frame 201 on the sliding plate 204, the rotating bidirectional screw 206 can drive the sliding frame plate on the sliding plate 204 to move towards each other along the axis of the bidirectional screw 206 under the action of the slide frame 201. This makes the protective frame plate 205 move closer to the transformer and contact it, thus achieving limiting protection when the transformer hoisting pipe moves.

[0026] According to another embodiment of the present invention, such as Figure 4 As shown, the lower end of the frame 101 is provided with two support frames 103 corresponding to the left and right positions. The lower end of each support frame 103 is rotatably equipped with two casters 104. The interior of each support frame 103 is provided with two hydraulic push rods 301. The telescopic ends of the four hydraulic push rods 301 are provided with support plates 302. The casters 104 allow the operator to flexibly move the hoisting device to the designated hoisting position. The controller 106 controls the hydraulic push rods 301 to operate. The telescopic ends drive the support plates 302 to move downwards, supporting the hoisting device and lifting the casters 104 off the ground, thereby ensuring that the hoisting device is more stable when hoisting the transformer.

[0027] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited, and other modifications or equivalent replacements of the technical solutions of the present application made by those skilled in the art should be covered in the scope of the claims of the present application, as long as they do not deviate from the spirit and scope of the technical solutions of the present application.
