Description

Technical Field

[0001] The utility model belongs to the technical field of lifting structures, in particular to a lifting device for a transformer substation cover. Background Art

[0002] Currently, new substation construction involves prefabricating numerous cement panels to cover the entrances and exits of indoor cable trenches. To facilitate handling and sealing, construction workers typically reserve two handling holes on each end of the panels during prefabrication. Currently, workers typically use ropes threaded through these two holes for transport. This restricts rope selection and handling methods, slowing down transport speeds. Furthermore, if the ropes fail to securely thread through the holes or if workers mishandle the panels, the panels can easily fall, causing personal injury or equipment damage. Utility Model Content

[0009] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention with reference to the accompanying drawings:

[0018] like Figure 1-5As shown, a device for lifting the substation cover comprises a handle 1, a cylinder 2 and a pull rod 3. The handle 1 is hollow in a square shape, which is convenient for construction workers to grasp and lift. The lower end of the handle 1 is vertically connected to the cylinder 2. The interior of the cylinder 2 is hollow, with openings at both ends. A partition 7 is provided in the cylinder 2 to effectively fix the position of the spring a6. The pull rod 3 passes through the handle 1 and the partition 7 in the cylinder 2 in sequence. A round hole is provided in the middle of the partition 7 to facilitate the pull rod 3 to move up and down in the partition 7. A baffle 5 is provided on the rod body of the pull rod 3 near the upper end opening of the cylinder 2. A spring a6 is sleeved between the baffle 7 and the baffle 5. The baffle 5 effectively stabilizes the spring a6, and as the pressing plate 4 presses the pull rod 3 downward, the baffle 5 squeezes the spring a6 downward. A long strip pressing plate 4 is welded vertically at the end. When the pressing plate 4 is not pressed downward, it is placed parallel to the long strip through hole A101 at the upper end of the handle 1. When the construction personnel press downward, the construction personnel rotate the pressing plate 4 and the through hole A101 to cross and fix them at the upper end of the through hole A101; a circular cross bar 8 is welded vertically at the lower end of the pull rod 3; a connecting structure is sleeved on the cross bar 8, and when the construction personnel press the pull rod 3 downward, the cross bar 8 brings the connecting structure out of the cylinder 2; the lower end of the connecting structure is movably connected with a U-shaped card 15, which is clamped into the two circular holes at one end of the cover by stretching the U-shaped card 15. The construction personnel can pull up the cover by pulling it upward. If the cover needs to be moved, it only needs to be clamped and fixed in the two circular holes at both ends of the cover through two devices for movement.

[0019] Specifically, the connecting structure includes a connecting rod 11, a connecting piece 12, a base 13, and a hanging ring 9; the outer walls of the two end portions of the cross bar 8 are provided with external threads, and the external threads are used in conjunction with the nuts 10; the two ends of the cross bar 8 are respectively provided with hanging rings 9 between the nuts 10, which effectively prevents the hanging rings 9 at both ends of the pull rod 3 from slipping out of the cross bar 8, and facilitates construction personnel to replace the connecting structure; the lower ends of the hanging rings 9 are respectively vertically connected to the connecting rods 11; the lower ends of the connecting rods 11 are respectively provided with connecting pieces 12; the lower ends of the connecting pieces 12 are all groove-shaped; the upper end of the base 13 is convex; the connecting pieces 12 are respectively plugged into the base 13 and movably connected by the rotating shaft 14, and effectively as the pull rod 3 moves downward, the two connecting rods extend to both sides under the action of the spring b16.

[0020] Specifically, U-shaped clips 15 are welded to the lower ends of the bases 13 ; the open ends of the U-shaped clips 15 are placed opposite to each other and are effectively stuck in the round holes to prevent the cover from shaking left and right.

[0021] Specifically, a spring b16 is welded transversely between the connecting rods 11 near the cross bar 8 , and when the pull rod 3 is pressed downward, the two connecting rods 11 are automatically stretched to both sides.

[0022] Specifically, the upper end surface of the handle 1 is provided with a long strip through hole A101; the lower end surface of the handle 1 is provided with a circular through hole B102 corresponding to the upper end opening of the cylinder 2.

[0023] During use, the construction worker presses the pressing plate 4 downward and rotates it to cross-fix it with the through hole A101 at the upper end of the handle 1. As the pressing plate 4 drives the pull rod 3 downward, the baffle 5 presses the spring a6 downward. Under the action of the partition 7 on the cylinder 2, the spring a6 is compressed, and the cross bar 8 at the lower end of the pull rod 3 extends the connecting structure out of the lower end opening of the cylinder 2. Then, the spring b16 between the two connecting rods 11 on the connecting structure stretches the two connecting rods 11 to both sides under the action of ductility. The construction worker only needs to insert the U-shaped clips 15 at the lower ends of the two connecting rods 11 into the two circular holes at one end of the cover plate, and then lift the cover plate upward through the handle 1. Finally, after the cover plate is moved, the construction worker removes the U-shaped clips from the circular holes. As the spring a6 stretches, the connecting structure is retracted into the cylinder 2, making it easier for the construction worker to carry.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
