[0034] In the present invention, “first” and “second” do not represent specific quantities and orders, but are merely used to distinguish names.

[0035] like Figure 1 and Figure 2 , Figure 3 , Figure 4 As shown, a transformer box lifting device in one embodiment of the utility model comprises a gantry 1, a lifting component 2, a flip component 3, a flip shell 4 and a clamping component 5; the flip shell 4 is provided with a receiving chamber for receiving the transformer box; the clamping component 5 is arranged on the outside of the receiving chamber, and comprises a plurality of clamping members 511 which can be moved relative to the receiving chamber, and the clamping members 511 are used to restrict the transformer box in the receiving chamber; the lifting component 2 is arranged on the gantry 1, and the flip component 3 is arranged on the lifting component 2; the flip component 3 is used to flip the flip shell 4, and the lifting component 2 is used to lift the flip component 3 and the flip shell 4.

[0036] The above-mentioned transformer box lifting device places the transformer box into the accommodating cavity, uses the clamping member 511 to clamp or clamp the transformer box to fix the position of the transformer box in the accommodating cavity, and then lifts the flip shell 4 through the lifting component 2. After the flip shell 4 is lifted to the preset position, the flip shell 4 is flipped by the flipping component 3, thereby ensuring that the transformer box remains stable, safe and reliable during the entire lifting and flipping process.

[0037] In one embodiment, the lifting component 2 includes a driving motor 21, a rotating rod 22, a sprocket chain assembly 23 arranged on both sides of the rotating rod 22, a gear rack unit 24 and a lifting seat 25; the sprocket chain assembly 23 includes a first sprocket 231, a transmission chain 232 and a second sprocket 233 that are sequentially driven, and the gear rack unit 24 includes a transmission gear and a transmission rack that are meshed and driven, the second sprocket 233 is connected to the transmission gear hub, and one end of the transmission rack is connected to the lifting seat 25.

[0038] In one embodiment, the lifting component 2 further includes a first guide unit 26, which includes a guide seat 261 fixedly mounted on the gantry 1 and a guide column 262 mounted on the lifting seat 25, wherein the guide seat 261 is provided with a guide hole adapted to fit the guide column 262. In this way, the guide column 262 is used to guide the lifting seat 25, thereby ensuring that the lifting component 2 is stable and reliable in the process of driving the flip component 3 and the flip shell 4 to perform the lifting action.

[0039] In one embodiment, the flip component 3 includes a mounting seat 31 disposed on the lifting seat 25, a flip frame 32 that can rotate relative to the mounting seat 31, a flip cylinder 33 disposed on the mounting seat 31, and a hinge seat 34 disposed on the flip frame 32, and the output rod end of the flip cylinder 33 is hinged to the hinge seat 34; the flip shell 4 is disposed on the flip frame 32. In this way, the output rod of the flip cylinder 33 extends and pushes the hinge seat 34, thereby driving the flip frame 32 to flip.

[0040] In one embodiment, the turning cylinder 33 is rotatably connected to the mounting base 31 via a rotating base 35. In this way, the turning cylinder 33 changes its angle during the turning process, and the rotating base 35 is used to overcome the rotation torque.

[0041] In one embodiment, the flip component 3 further includes a limiter 36 disposed on the mounting seat 31, and the limiter 36 is used to place the flip frame 32 on top, thereby limiting the flip angle of the flip frame 32. In this way, the limiter 36 is used to place the flip frame 32 on top, thereby limiting the flip angle of the flip frame 32, and ensuring that the flip angle of the flip component 3 meets the use requirements.

[0042] In one embodiment, the clamping component 5 includes two clamping assemblies 51 symmetrically arranged on the left and right sides of the flip shell 4, and the clamping assembly 51 includes a fixed seat 512 arranged on the mounting seat 31, a clamping cylinder 513 arranged on the fixed seat 512, and a movable seat 514 driven by the clamping cylinder 513, and the clamping member 511 is arranged on the movable seat 514. In this way, the movable seat 514 is driven to move by the clamping cylinder 513, so that the clamping member 511 moves relative to the flip shell 4, thereby fixing the transformer box in the flip shell 4.

[0043] In one embodiment, the clamping assembly 51 includes a second guide unit 52, which includes a sliding seat 521 disposed on a fixed seat 512 and a sliding rail 522 disposed on a movable seat 514, and the sliding rail 522 is adapted to the sliding seat 521.

[0044] In one embodiment, the clamping member 5 includes a limit assembly 53 disposed on the top side of the flip shell 4, and the limit assembly 53 is limited by the top of the transformer box. In this way, the limit assembly 53 is placed on the top of the transformer box to limit the position, which is convenient for adapting to transformer boxes of different heights and expanding the application range of the lifting device.

[0045] In one embodiment, the flip component 3 further includes a safety bar 37 disposed on the flip frame 32. Since the length and width of the flip shell 4 are different, when the flip shell 4 is placed vertically, it may be difficult for the operator to notice the avoidance space required for flipping. Therefore, by arranging the safety bar 37 on the flip frame 32, the operator can be aware of the size of the avoidance space, which plays a certain warning role.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
