Description

Technical Field

[0001] This utility model relates to the field of transformer installation technology, specifically a transformer lifting device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It mainly consists of a primary coil, a secondary coil, and an iron core. It can be used for voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. During the installation of a transformer, it is often necessary to lift it for installation.

[0003] Existing lifting devices typically place the transformer to be installed inside a frame with a rotating door at the front. When the installation position is reached, the operator opens the rotating door at the front of the frame to remove and install the transformer. However, the existing frame is generally closed and cannot be opened to the sides, which restricts the operator's range of motion when removing the transformer. Summary of the Invention

[0004] The purpose of this utility model is to provide a lifting device for transformers to solve the problem that the existing device frame restricts the operator's position, making it impossible to quickly and easily remove the transformer from the frame.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for a transformer, comprising a base and vertical rods fixedly installed on both sides of the upper end of the base, a horizontal plate fixedly installed on the upper end of the two sets of vertical rods, a hydraulic cylinder fixedly installed in the middle of the upper end of the base, a stabilizing block fixedly installed at the output end of the hydraulic cylinder, stabilizing members installed on the outer walls of the vertical rods on both sides of the stabilizing block, a placement plate fixedly installed at the front end of the two sets of stabilizing members, a first vertical plate and a second vertical plate rotatably installed on both sides of the upper end of the placement plate, an unfolding structure installed between the first vertical plate and the second vertical plate, the unfolding structure comprising two fixing blocks fixedly installed on the upper end of the second vertical plate, a connecting screw installed in the internal thread of the fixing block, a connecting block rotatably installed on one side of the connecting screw, a corresponding connecting groove opened on one side of the first vertical plate located on the side of the connecting block, and the connecting block fitting against the upper end of the second vertical plate.

[0006] Preferably, the lower end of the placement plate is provided with an anti-slip structure, which includes a fixing member fixedly installed at the lower end of the placement plate. An adjusting screw is provided inside the fixing member. An anti-slip plate is rotatably installed at the upper end of the adjusting screw. A reserved groove is opened at the lower end of the placement plate located at the upper end of the anti-slip plate. The anti-slip plate passes through the reserved groove and is located at the upper end of the placement plate.

[0007] Preferably, the second vertical plate has a stacking groove at both the front and rear ends on one side, and one end of the first vertical plate is placed inside the corresponding stacking groove.

[0008] Preferably, a second fixing rod is fixedly provided at the upper and lower ends of the inner walls on both sides of the stabilizing member, and a first fixing rod is fixedly provided on both sides of the inner walls at the front and rear ends of the stabilizing member, and bearings are installed on the outer walls of the second fixing rod and the first fixing rod.

[0009] Preferably, support plates are fixedly provided on both sides of the lower end of the fastener.

[0010] Preferably, two sets of round rods are fixedly installed at the lower end of the horizontal plate, and the stabilizing block is sleeved on the outer wall of the two sets of round plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1) By setting up an unfolding structure, when the placement plate, the first vertical plate, the second vertical plate, and the transformer are moved to a high position, the operators can unfold the first vertical plate and the second vertical plate, so that the transformer can be taken out from both sides. This avoids the first vertical plate and the second vertical plate restricting the operator's position and speeds up the efficiency of the operator in taking out the transformer.

[0013] 2) By setting up an anti-slip structure, the front end of the transformer at the top of the placement plate can be limited by the upward movement of the anti-slip plate, so as to prevent the transformer from sliding during the lifting process of the placement plate and better ensure the safety of the lifting.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Combination Figures 1-4 A transformer lifting device includes a base 1 and vertical rods 2 fixedly installed on both sides of the upper end of the base 1. Horizontal plates are fixedly installed on the upper ends of the two sets of vertical rods 2. A hydraulic cylinder 3 is fixedly installed in the middle of the upper end of the base 1. A stabilizing block 4 is fixedly installed at the output end of the hydraulic cylinder 3. Stabilizing members 5 are installed on the outer walls of the vertical rods 2 on both sides of the stabilizing block 4. Placement plates 6 are fixedly installed at the front ends of the two sets of stabilizing members 5. A first vertical plate 7 and a second vertical plate 8 are rotatably installed on both sides of the upper end of the placement plate 6. An unfolding structure 9 is installed between the first vertical plate 7 and the second vertical plate 8. The unfolding structure 9 includes two fixing blocks 10 fixedly installed on the upper end of the second vertical plate 8. A connecting screw 11 is provided inside the fixing block 10. A connecting block is rotatably installed on one side of the connecting screw 11. A corresponding connecting groove 12 is opened on one side of the first vertical plate 7 located on the side of the connecting block. The connecting block is in contact with the upper end of the second vertical plate 8.

[0021] See Figure 2 , Figure 4 The second vertical plate 8 has a mounting groove 13 on both the front and rear ends of one side. One end of the first vertical plate 7 is placed inside the corresponding mounting groove 13. Support plates are fixedly installed on both sides of the lower end of the fastener 15. Two sets of round rods are fixedly installed at the lower end of the horizontal plate. The stabilizing block 4 is sleeved on the outer wall of the two sets of round plates.

[0022] By setting the placement groove 13, it can be ensured that one side of the first vertical plate 7 and one side of the second vertical plate 8 are stably connected, and the vertical round rod can ensure the stability of the stabilizing block 4 when it moves up and down. Example 2

[0023] See Figure 4 Based on Embodiment 1, the lower end of the placement plate 6 is provided with an anti-slip structure 14. The anti-slip structure 14 includes a fixing member 15 fixedly installed at the lower end of the placement plate 6. An adjusting screw 16 is threaded inside the fixing member 15. An anti-slip plate 17 is rotatably installed at the upper end of the adjusting screw 16. A reserved groove is opened at the lower end of the placement plate 6 located at the upper end of the anti-slip plate 17. The anti-slip plate 17 passes through the reserved groove and is located at the upper end of the placement plate 6.

[0024] Specifically, the fixing part 15 is used to thread the adjusting screw 16, the adjusting screw 16 is used to adjust the up and down movement of the anti-slip plate 17, and the anti-slip plate 17 is used to limit the front end of the transformer at the upper end of the placement plate 6 to prevent the transformer from sliding and falling. Example 3

[0025] See Figure 3 Furthermore, based on Embodiment 1 and Embodiment 2, it is further found that the upper and lower ends of the inner walls on both sides of the stabilizing member 5 are fixedly provided with second fixing rods 19, and the inner walls of the front and rear ends of the stabilizing member 5 are fixedly provided with first fixing rods 18. The outer walls of the second fixing rods 19 and the first fixing rods 18 are equipped with bearings 20.

[0026] Specifically, multiple bearings 20 contact the outer wall of the vertical rod 2 respectively. When the stabilizing block 4 drives the two sets of stabilizing members 5 to move, the overall stability can be enhanced.

[0027] In actual operation, the transformer to be lifted is placed on the upper end of the placement plate 6. The adjusting screw 16 is rotated, which causes the adjusting screw 16 to move the anti-slip plate 17 upward, limiting the front end of the transformer. The hydraulic cylinder 3 is activated, which causes the stabilizing block 4 to move upward on the outer wall of the vertical round rod, and at the same time, it causes the two sets of stabilizing parts 5 to move upward. When the transformer needs to be removed from a high position, the docking screw 11 is rotated, which causes the docking screw 11 to move the docking block out of the docking groove 12. The first vertical plate 7 and the second vertical plate 8 are flipped over, making it convenient for the operators to lift the transformer out from the upper end of the placement plate 6.

[0028] When it is necessary to remove the transformer from the front end of the placement plate 6, rotate the adjusting screw 16, so that the adjusting screw 16 drives the anti-slip plate 17 to move down. The upper end of the anti-slip plate 17 is hidden inside the reserved slot and will not obstruct the lower end of the transformer.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
