[0041] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments

[0042] This embodiment relates to a transformer immersion detection device convenient for hoisting. In terms of the overall structure, as Figure 1 shown, it includes a hoisting frame 1, a lifting mechanism 3, a sliding mechanism 4, and a lifting appliance 5

[0043] Among them, a water tank 2 for immersing the transformer is arranged on one side of the bottom of the hoisting frame 1. The lifting mechanism 3 is arranged on the hoisting frame 1 to lift the transformer on the ground to the upper part of the water tank 2. The sliding mechanism 4 is horizontally arranged on the hoisting frame 1 to drive the lifting mechanism 3 to slide and move the transformer to the top of the water tank 2. The lifting appliance 5 is fixedly installed at the bottom of the lifting mechanism 3, and the transformer is suspended on the lifting appliance 5

[0044] It is worth mentioning that the lifting frame 1 has a parallel top and is provided with multiple legs at the bottom to ensure that the sliding mechanism 4 can reciprocally slide on the top of the lifting frame 1. First, the lifting rings of the transformer are suspended on the lifting tool 5, and then the transformer is lifted by the lifting mechanism 3. Then, the sliding mechanism 4 drives the lifting mechanism 3 and the transformer to move towards the top of the water tank 2. After moving to the top of the water tank 2, the transformer is pressed down into the water of the water tank 2 by the lifting mechanism 3 for immersion detection. That is to say, the lifting frame 1 straddles the top of the water tank 2, and the water tank 2 is located on one side of the lifting frame 1 to ensure that the transformer can be lifted on one side of the water tank 2.

[0045] Based on the above overall introduction, an exemplary structure of the transformer immersion detection device facilitating lifting in this embodiment is as Figure 2 shown. The sliding mechanism 4 includes two tracks 401 arranged oppositely on the top of the lifting frame 1 and a cross plate 402 straddling the two tracks 401. The lifting mechanism 3 is arranged to pass through the cross plate 402 for lifting and lowering, and the cross plate 402 reciprocally slides on the tracks 401 through the driving component 403.

[0046] It should be noted that the tracks 401 are laid along the length direction of the lifting frame 1. The cross plate 402 is connected to the tracks 401 through sliders 404, and the sliders 404 can slide on the tracks 401 to drive the cross plate 402 to move. The cross plate 402 is located between the two tracks 401. Such a setting ensures uniform force on the cross plate 402. The lifting mechanism 3 is installed on the cross plate 402, so the lifting mechanism 3 can reciprocally slide on the top of the water tank 2 following the cross plate 402. The driving component 403 is installed at the bottom of the tracks 401, and the cross plate 402 is connected to the mobile end of the driving component 403 to ensure that the cross plate 402 can automatically slide.

[0047] As a preferred implementation manner, as Figure 3 shown, in this embodiment, the driving component 403 includes belt wheels 4031 rotatably arranged at both ends of the lifting frame 1 and a first motor 4032 for driving the two belt wheels 4031 to rotate. The two belt wheels 4031 are driven by a synchronous belt 4033, and the synchronous belt 4033 drives the cross plate 402 to reciprocally slide. A driven rod 4034 for driving the cross plate 402 to move is fixedly arranged on the synchronous belt 4033, and the driven rod 4034 is fixedly connected to the cross plate 402.

[0048] It should be noted that mounting plates are fixedly installed on the legs of the hoisting frame 1, the first motor 4032 is fixed on the mounting plate, one of the pulleys 4031 is key-connected to the drive shaft of the first motor 4032, the other pulley 4031 is rotationally connected to another mounting plate, a synchronous belt 4033 is sleeved on the two pulleys 4031, when the first motor 4032 rotates, the synchronous belt 4033 can be driven to move through the two pulleys 4031, the driven rod 4034 is clamped and fixed on the synchronous belt 4033, the top of the driven rod 4034 and the cross plate 402 can be fixed by bolts or by welding, when the synchronous belt 4033 drives the driven rod 4034 to move, the driven rod 4034 drives the cross plate 402 to move.

[0049] As a preferred embodiment, as Figure 4 shown, in this embodiment, the lifting mechanism 3 includes a lead screw 301 passing through the cross plate 402 and a gearbox 302 fixedly arranged on the cross plate 402 to drive the lead screw 301 to lift and lower. There are two groups of the lead screw 301 and the gearbox 302 oppositely arranged on the cross plate 402. It should be noted that the lead screw 301 passes through the gearbox 302, and the gearbox 302 can drive the lead screw 301 to lift and lower. The gearbox 302 is a common transmission device in the prior art, and its structure is a worm and worm gear structure. The worm and worm gear are rotatably arranged in the gearbox 302, a nut is fixedly arranged inside the worm gear, the lead screw 301 is threadedly connected to the nut. When the second motor 303 drives the worm to rotate, since the worm and the worm gear are meshed, the worm gear and the nut rotate accordingly, and the rotation of the nut can drive the lead screw 301 to complete the lifting and lowering action. Since the gearbox 302 is prior art, the internal structure is not shown in the drawings. There are two groups of the gearbox 302, so a transmission shaft passes through the motor, and both ends of the transmission shaft are connected to the two worms through couplings respectively.

[0050] As a preferred embodiment, as Figure 5 shown, in this embodiment, the spreader 5 includes a cross plate 501 fixedly arranged at the bottom ends of the two lead screws 301 and hooks 502 slidably arranged at both ends of the cross plate 501. The hooks 502 are inserted into the lifting rings of the transformer. A slideway 503 for the hooks 502 to slide is arranged at the bottom of the cross plate 501, and a slide bar 504 for assisting the sliding of the hooks 502 is arranged at the top of the cross plate 501.

[0051] It should be noted that the cross plate 501 follows the lead screw 301 to lift and lower, the hooks 502 can hook the lifting rings of the transformer, so as to realize lifting the transformer. Hooks 502 are arranged at both ends of the cross plate 501 to ensure that the transformer can be lifted horizontally. The hooks 502 can slide in the slideway 503, which is convenient for inserting the hooks 502 into the lifting rings of the transformer. The slide bar 504 can push the movement of the hooks 502, thus facilitating the operation. The slide bar 504 is inserted into the sleeve of the cross plate 501 to ensure the stability of the sliding of the slide bar 504.

[0052] Preferably, still as Figure 5 shown, a spring 505 is arranged between the sliding rod 504 and the cross plate 501, and the spring 505 pushes the hook 502 to always be stressed towards the lifting ring of the transformer. Specifically, the spring 505 is sleeved on the sliding rod 504, and the two ends of the spring 505 are respectively located at the sleeve of the cross plate 501 and the end of the sliding rod 504. Due to the elastic force of the spring 505, it can ensure that the hook 502 is always stressed towards one side. Such a setting can ensure that the hook 502 is always inserted into the lifting ring of the transformer and prevent the hook 502 from falling off.

[0053] The transformer immersion detection device convenient for hoisting in this embodiment improves the operation efficiency and reduces the labor intensity through an automated hoisting and immersion detection system; improves the accuracy and reliability of the hoisting process through the precisely controlled and synchronously moving driving component 403; improves the flexibility and safety of the transformer hoisting through the bidirectionally controlled and stably lifting lifting mechanism 3; improves the hoisting efficiency through the design of the lifting tool 5 for quick fixing and releasing; ensures the smoothness of the transformer hoisting process through the design of the slideway 503 and the sliding rod 504 for improving the sliding efficiency of the hook 502; and improves the safety of the hoisting process through the design of the spring 505 for ensuring the tight connection between the hook 502 and the lifting ring of the transformer.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
