Description

Technical Field

[0001] This utility model relates to the field of cold-rolled coil transfer technology, specifically to a multi-functional lifting device capable of flipping cold-rolled coils. Background Technology

[0002] Cold-rolled steel coils are made from hot-rolled coils at room temperature below the recrystallization temperature. Since cold-rolled steel coils are usually in rolls, lifting equipment is needed for handling them. However, the lifting equipment in the existing technology cannot change the orientation of the cold-rolled steel coil after it is lifted. When the lifting orientation is incorrect, the cold-rolled steel coil can only be put down and lifted again, which is time-consuming, labor-intensive and reduces work efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed and easy-to-use multifunctional lifting tool for flipping cold-rolled coils, which can effectively solve the defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it comprises a fixing plate, a clamping plate, and a clamping block, wherein clamping plates are symmetrically arranged on the lower side of the fixing plate, and clamping blocks are fixed on adjacent side walls of the two clamping plates; it further comprises:

[0005] A bidirectional lead screw is embedded in a fixed plate and screwed into it with bearings. Both ends of the bidirectional lead screw are screwed into a movable frame. The front and rear vertical plates of the lower side wall of the movable frame pass through the sliding groove on the lower side wall of the fixed plate and are connected to the upper side wall of the clamping plate.

[0006] A clamping motor is embedded and fixed in a fixing plate, and the output shaft of the clamping motor is connected to the middle end of a bidirectional lead screw through a bevel gear pair.

[0007] The mounting bracket is in the shape of an inverted "U". The mounting bracket has a fixed seat inside, and a connecting plate is connected to the lower side of the fixed seat through a rotating mechanism.

[0008] A flip motor is embedded and fixed in a connecting plate, and the output shaft of the flip motor is fixedly connected to the upper surface of the fixing plate.

[0009] The above technical solution involves placing the cold-rolled coil between the clamping plates on both sides, starting the clamping motor, which drives the bidirectional lead screw to rotate via a bevel gear pair, and the bidirectional lead screw drives the moving frame to move via threads at both ends, which in turn drives the clamping plates to move until the clamping blocks on the clamping plates are engaged with the ends of the coil. When it is necessary to flip the coil, the rotating mechanism drives the connecting plate to rotate to one side of the mounting frame, and then the flipping motor is started. The flipping motor drives the fixed plate to rotate, and the fixed plate drives the cold-rolled coil to flip to a suitable angle via the clamping plates and clamping blocks.

[0010] As a further improvement of this utility model, an annular slide rail is fixed on the upper surface of the fixing plate, and the annular slide rail is slidably disposed in the groove on the lower surface of the connecting plate.

[0011] The above technical solution can increase the stability of the fixed plate during rotation.

[0012] As a further improvement of this utility model, the rotating mechanism includes:

[0013] Two rotating tubes are provided, and they are respectively slidably disposed in the two side walls of the fixed base via convex rings. The lower side of the outer ring wall of the rotating tube is fixedly connected to the connecting plate.

[0014] A rotating motor is embedded and fixed in a fixed base. The output shaft of the rotating motor is connected to a rotating rod through a worm gear pair. The rotating rod is screwed into the fixed base through bearings. After passing through the side wall of the fixed base, both ends of the rotating rod are located in the rotating tube.

[0015] Two rotating gears are provided, each sleeved and fixed on one end of the rotating rod located inside the rotating tube. The rotating gears are meshed with the tooth grooves on the inner annular wall of the rotating tube.

[0016] Using the above technical solution, the rotating motor is started, and the rotating motor drives the rotating rod to rotate through the worm gear pair. The rotating rod drives the rotating gears on both sides to rotate, and the rotating gears drive the rotating tube to rotate, thereby driving the connecting plate to rotate.

[0017] As a further improvement of this utility model, the end of the rotating tube away from the fixed base is screwed with a fixed tube by a convex ring, and the other end of the fixed tube is fixed to the vertical plates on both sides of the mounting frame.

[0018] The above technical solution can increase the stability of the rotating tube during rotation without affecting its rotation.

[0019] As a further improvement of this utility model, the clamping blocks are all cone-shaped, and anti-slip pads are sleeved on the outer side of the clamping blocks.

[0020] Through the above technical solution, the tapered clamping block can be applied to drums with different inner diameters, and the anti-slip pad can increase the friction between the clamping block and the drum.

[0021] As a further improvement of this utility model, insert plates are inserted inside the clamping plate, and the upper side of the insert plates is fixedly connected to the vertical plates on both sides of the movable frame. The insert plates are connected to the clamping plate by threads.

[0022] With the above technical solution, the bolts between the insert plate and the clamping plate can be loosened according to the thickness of the cold-rolled coil wound on the drum. The clamping plate will drive the clamping block to move until the distance between the clamping block and the fixed plate meets the requirements. Then the bolts between the insert plate and the clamping plate will be tightened.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: The multi-functional lifting device for flipping cold-rolled coils described in this utility model can be flipped according to the requirements, so that the cold-rolled coils can be rotated to a suitable angle, which improves adaptability. This utility model has the advantages of reasonable design and low manufacturing cost. Attached Figure Description

Each clamping block 3 is conical in shape, and an anti-slip pad 14 is fitted and adhered to the outer side of each clamping block 3. The conical shape of the clamping blocks 3 allows them to be used with drums of different inner diameters, and the anti-slip pad 14 increases the friction between the clamping blocks 3 and the drum. It also includes:

[0033] A bidirectional lead screw 4 is embedded in and screwed into a fixed plate 1 via bearings. Both ends of the bidirectional lead screw 4 are threaded to a movable frame 5. The front and rear vertical plates of the lower side wall of the movable frame 5 pass through the sliding groove on the lower side wall of the fixed plate 1 and are connected to the upper side wall of the clamping plate 2. Insert plates 15 are inserted into the interior of the clamping plate 2. The upper side of the insert plates 15 is welded and fixed to the vertical plates on both sides of the movable frame 5. The insert plates 15 are threaded to the clamping plate 2. According to the thickness of the cold-rolled coil wound on the coil, the bolts between the insert plates 15 and the clamping plate 2 can be loosened, and the clamping plate 2 can drive the clamping block 3 to move until the distance between the clamping block 3 and the fixed plate 1 meets the requirements. Then the bolts between the insert plates 15 and the clamping plate 2 are tightened.

[0034] The clamping motor 6 is embedded in the fixing plate 1 and fixed with bolts. The output shaft of the clamping motor 6 is connected to the middle end of the double-acting lead screw 4 through a bevel gear pair.

[0035] Mounting bracket 7 is arranged in an inverted "U" shape. A fixing seat 8 is welded and fixed inside the mounting bracket 7. A connecting plate 10 is connected to the lower side of the fixing seat 8 through a rotating mechanism 9. An annular slide rail 12 is welded and fixed on the upper surface of the fixing plate 1. The annular slide rail 12 is slidably arranged in a groove on the lower surface of the connecting plate 10, which can increase the stability of the fixing plate 1 when it rotates.

The lower side of the outer ring wall of the rotating tube 9-1 is welded and fixed to the connecting plate 10. The end of the rotating tube 9-1 away from the fixed base 8 is screwed with a fixed tube 13 via a convex ring. The other end of the fixed tube 13 is welded and fixed to the vertical plates on both sides of the mounting frame 7, which can increase the stability of the rotating tube 9-1 when rotating without affecting its rotation.

[0040] A rotating motor 9-2 is embedded in and fixed in a fixed seat 8 by bolts. The output shaft of the rotating motor 9-2 is connected to a rotating rod 9-3 through a worm gear pair. The rotating rod 9-3 is screwed into the fixed seat 8 through bearings.

[0042] When using this utility model, the cold-rolled coil is placed between the clamping plates 2 on both sides. The clamping motor 6 is started. The clamping motor 6 drives the double-acting screw 4 to rotate through the bevel gear pair. The double-acting screw 4 drives the moving frame 5 to move through the threads at both ends. The moving frame 5 drives the clamping plate 2 to move until the clamping block 3 on the clamping plate 2 is locked into the two ends of the coil. When it is necessary to flip, the rotating motor 9-2 is started. The rotating motor 9-2 drives the rotating rod 9-3 to rotate through the worm gear pair. The rotating rod 9-3 drives the rotating gears 9-4 on both sides to rotate. The rotating gears 9-4 drive the rotating tube 9-1 to rotate, thereby driving the connecting plate 10 to rotate to one side of the mounting frame 7. Then the flipping motor 11 is started. The flipping motor 11 drives the fixing plate 1 to rotate. The fixing plate 1 drives the cold-rolled coil to flip to a suitable angle through the clamping plate 2 and the clamping block 3.

[0043] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0044] 1. The fixed plate 1 can be rotated to a suitable angle by the rotating mechanism 9 as needed, and then rotated by the flipping motor 11 to flip it accordingly, so that the cold-rolled coil can be rotated to a suitable angle, thus improving adaptability.
