Description

Technical Field

[0001] The utility model belongs to the technical field of steel coil loading, in particular to a hoisting mechanism for steel coil loading. Background Art

[0002] Steel coils are steel materials formed into coils by hot pressing and cold pressing. In order to facilitate storage and transportation, and to facilitate various processing (such as processing into steel plates, steel strips, etc.), the formed coils are mainly hot-rolled coils and cold-rolled coils. Hot-rolled coils are processed products before the steel billet recrystallizes, and cold-rolled coils are the subsequent processing of hot-rolled coils. When transporting steel coils, they need to be loaded with the help of external cranes and other equipment, so a lifting mechanism is needed for loading the steel coils.

[0003] Among them, after searching, it was found that there is an application number CN202320634370.5, which discloses a sling device for lifting steel coils, including a C-shaped steel coil sling body, wherein the C-shaped steel coil sling body includes a lifting beam and a load-bearing beam that are parallel to each other and spaced apart, and has the following features: in the initial state, the telescopic cylinder A is in a retracted state, and the distance between the pressure plate A and the load-bearing beam is the shortest. When the load-bearing beam is inserted into the inner hole of the steel coil, the upper part of the inner hole of the steel coil is supported on the load-bearing beam, and then the telescopic cylinder A is controlled to extend, and the telescopic cylinder A drives the pressure plate A to move away from the load-bearing beam. The steel coil is moved in the hole, and finally the pressure plate A is pressed on the bottom of the inner hole of the steel coil, which makes the steel coil more firmly clamped, avoids the displacement of the steel coil and the sling caused by shaking, makes the lifting more stable, and improves safety. The steel coil is fixed at the same time by the clamping device in the hole and the clamping device on the outer wall, which makes the steel coil more firmly clamped, avoids the displacement of the steel coil and the sling caused by shaking, makes the lifting more stable, and improves safety. The two ends of the connecting plate A and the connecting plate B are respectively surrounded by corresponding vertical plates to form a rectangular frame structure. The rectangular frame A protects the telescopic cylinder A and has the advantage of being convenient to install.

[0004] However, after research, it was found that when the device is used to hoist a long steel coil, the inner hole clamping device and the outer wall clamping device cannot be clamped at the center of the steel coil, resulting in an unstable center of gravity of the steel coil. The clamping effect of the steel coil is not good enough, and it is not suitable for hoisting a long steel coil. It is not flexible enough to use, and when unloading the steel coil, the lifting rope of the external crane is prone to shaking, and it is not easy to locate the falling position of the steel coil, making unloading difficult. Therefore, a new device is provided to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a lifting mechanism for loading steel coils, in order to solve the above-mentioned problems of insufficient fixing effect on steel coils, insufficient flexibility in use, and great difficulty in unloading.

[0006] The technical solution adopted by the utility model is as follows: a hoisting mechanism for loading steel coils onto a vehicle, comprising a hoisting frame, a hoisting ring being fixedly installed on the top of the hoisting frame;

[0007] Hoisting mechanisms for fixing and hoisting steel coils of different lengths are arranged on both sides of the hoisting frame.

[0008] In which, the lifting mechanism comprises a connecting frame, a slide plate, a connecting column and an arc-shaped clamping plate, the connecting frames are symmetrically arranged on both sides of the lifting frame, and the connecting frames are arranged in an L shape, a slide plate is fixedly installed on one side of the connecting frame, and slide grooves matching the slide plate are symmetrically embedded on both sides of the lifting frame, and the slide plate is slidably connected to the inside of the slide groove, and a number of threaded holes are symmetrically arranged above the slide plate, and the lifting frame and the slide plate are fixedly fixed by fixing bolts, a connecting column is fixedly installed on one side of the connecting frame, and arc-shaped clamping plates are symmetrically and elastically connected on both sides of the connecting column through spring telescopic rods, winches are symmetrically installed on both sides above the lifting frame, and the starting end of the steel wire rope reel of the winch extends to the bottom of the lifting frame through the through groove and is connected to the connecting frame, and a pulley is rotatably connected to the bottom of the lifting frame near the through groove, a support plate is fixedly installed on one side of the connecting frame, and the upper surface of the support plate contacts the lower surface of the lifting frame, and an electric jack is installed below the other side of the connecting frame.

[0009] Among them, electric cylinders are symmetrically connected to the two sides of the lower side of the lifting frame through a rotating shaft, and the two ends of the electric cylinders are commonly connected to a clamp through a rotating shaft, and the clamp is composed of two arc-shaped plates connected by a rotating shaft, and reinforcement plates are symmetrically connected to the two sides of the clamp through a rotating shaft, and the reinforcement plates are arranged in an arc shape, and the reinforcement plate is elastically connected to a connecting plate facing the clamp, and the connecting plate is arranged in an arc shape, and a binding belt is connected to the other side of the reinforcement plate.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] 1. In the utility model, the positions of the two connecting frames can be pulled according to the length of the steel coil through the lifting mechanism, so that the spacing between the two connecting frames matches the length of the steel coil, and the two connecting columns are fixed to the steel coil from both ends of the center hole of the steel coil and from both sides of the steel coil, thereby ensuring the balance of the steel coil, and can clamp and fix steel coils of different lengths, which is more flexible to use.

[0012] 2. In the utility model, after the steel coil is clamped between the two connecting frames, the wire rope reel of the winch is slightly reeled up to tighten the wire rope between the winch and the connecting frame. The wire rope provides an upward pulling force for the connecting frame. The pulling force provided by the wire rope balances part of the gravity of the steel coil, avoiding that all the gravity of the steel coil is applied to the slide plate, causing the slide plate to break and be damaged. The support plate provides an upward supporting force for the lifting frame, avoiding that all the gravity of the lifting frame is applied to the slide plate, causing the slide plate to break and be damaged, making the connecting frame stronger and more durable.

[0013] 3. In the utility model, the electric jack is extended to push the steel coil off the ground for a distance, and then the electric cylinder is extended to push the two arc-shaped plates of the clamp to clamp the two sides of the steel coil. Then the staff assists in rotating the two reinforcement plates and ties the binding belts of the two reinforcement plates together through a rope tightener. The connecting plate is pressed on the lower surface of the steel coil under the action of elastic force. The clamp, reinforcement plate and binding belt together form an annular clamp to clamp the steel coil, thereby strengthening the fixing effect of the steel coil and making the lifting more stable.

[0014] 4. In the utility model, when unloading, the electric jack continues to extend, so that the bottom of the electric jack is supported in the carriage of the transport vehicle, and the connecting frame, the lifting frame and the steel coil are positioned to prevent the connecting frame, the lifting frame and the steel coil from shaking with the crane rope, making the unloading more stable.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the utility model:

[0022] Reference Figure 1-4 , a steel coil loading hoisting mechanism, comprising a hoisting frame 1, a hoisting ring 101 is fixedly installed above the hoisting frame 1;

[0023] Lifting mechanisms for fixing and lifting steel coils of different lengths are arranged on both sides of the lifting frame 1 .

[0024] Reference Figure 1-2 In this embodiment, the hoisting mechanism includes a connecting frame 201, a slide plate 2011, a connecting column 202 and an arc-shaped clamping plate 2021. The connecting frames 201 are symmetrically arranged on both sides of the hoisting frame 1, and the connecting frames 201 are arranged in an L shape. The slide plate 2011 is fixedly installed on one side of the connecting frame 201, and the sliding grooves matching the slide plate 2011 are symmetrically embedded on both sides of the hoisting frame 1, and the slide plate 2011 is slidably connected inside the sliding groove, and a plurality of threaded holes are symmetrically arranged above the slide plate 2011. The hoisting frame 1 and the slide plate 2011 are fixed by fixing bolts, and the connecting column 202 is fixedly installed on one side of the connecting frame 201, and the arc-shaped clamping plates 2021 are symmetrically elastically connected on both sides of the connecting column 202 through spring telescopic rods;

[0025] The staff pushes the device to the steel coil, then removes the fixing bolts between the lifting frame 1 and the slide plate 2011, pulls the connecting frame 201, and then pushes the device so that the steel coil is between the two connecting frames 201. The staff pushes the connecting frame 201 to one end of the steel coil, so that the connecting column 202 passes through the center hole of the steel coil. The two arc-shaped clamping plates 2021 are tightly clamped on both sides of the inner wall of the steel coil under the elastic action of the spring telescopic rod, and the connecting column 202 is fixed inside the steel coil. Then, the connecting column 202 on one side of the other connecting frame 201 is pushed into the other end of the center hole of the steel coil, and the lifting frame 1 and the slide plate 2011 are fixed by fixing bolts, so that the two connecting frames 201 are tightly clamped at both ends of the steel coil respectively, and the steel coil is fixed between the two connecting frames 201. The external crane matching hook is hung on the lifting ring 101, and the entire device and the steel coil are hoisted into the transport carriage.

[0026] Reference Figure 1-2 In this embodiment, winches 103 are symmetrically installed on both sides above the hoisting frame 1, and the starting end of the wire rope of the winch 103 extends to the bottom of the hoisting frame 1 through the through slot and is connected to the connecting frame 201, and a pulley is rotatably connected to the bottom of the hoisting frame 1 near the through slot;

[0027] When the staff is pulling the connecting frame 201, the torque motor of the winch 103 drives the supporting wire rope reel to unwind. After the connecting frame 201 is fixed to both ends of the steel reel, the torque motor of the winch 103 drives the supporting wire rope reel to slightly reel in, tightening the wire rope between the winch 103 and the connecting frame 201. The wire rope provides an upward pulling force for the connecting frame 201, making the connecting frame 201 more stable.

[0028] Reference Figure 1-2 In this embodiment, a support plate 2012 is fixedly installed on one side of the connecting frame 201, and the upper surface of the support plate 2012 is in contact with the lower surface of the hanging frame 1;

[0029] The support plate 2012 provides an upward support force for the hanging frame 1, so as to prevent all the gravity of the hanging frame 1 from being applied to the slide plate 2011 and causing the slide plate 2011 to break and be damaged, thereby making the connecting frame 201 more solid and durable.

[0030] Reference Figure 1-2 In this embodiment, an electric jack 2 is installed at the bottom of the other side of the connecting frame 201;

[0031] The electric jack 2 extends to move the connecting frame 201, the hoisting frame 1 and the steel coil up a certain distance at the same time. When unloading, the electric jack 2 continues to extend so that the bottom of the electric jack 2 is supported in the carriage of the transport vehicle, and the connecting frame 201, the hoisting frame 1 and the steel coil are positioned to prevent the connecting frame 201, the hoisting frame 1 and the steel coil from shaking with the crane rope, making the unloading more stable.

[0032] Reference Figure 1-4 In this embodiment, the two sides below the hanging frame 1 are symmetrically connected to the electric cylinder 1021 through the rotating shaft, and the ends of the two electric cylinders 1021 are commonly connected to the clamp 102 through the rotating shaft, and the clamp 102 is formed by two arc-shaped plates connected by the rotating shaft. The two sides of the clamp 102 are symmetrically connected to the reinforcing plate 104 through the rotating shaft, and the reinforcing plate 104 is set in an arc shape. The reinforcing plate 104 is elastically connected to the side facing the clamp 102 with a connecting plate 1042, and the connecting plate 1042 is set in an arc shape, and the other side of the reinforcing plate 104 is connected to a binding belt 1041;

[0033] The electric jack 2 extends and pushes the steel coil off the ground for a distance. Then the electric cylinder 1021 extends and pushes the two arc-shaped plates of the clamp 102 to clamp the two sides of the steel coil. Then the staff assists in rotating the two reinforcement plates 104 and tightens the binding belts 1041 of the two reinforcement plates 104 together through a rope tightener. The connecting plate 1042 is pressed on the lower surface of the steel coil under the action of elastic force. The clamp 102, reinforcement plate 104 and binding belt 1041 together form an annular clamp to clamp the steel coil, thereby strengthening the fixing effect of the steel coil and making the lifting more stable.

[0034] Reference Figure 1-4 In this embodiment, the electric cylinder 1021, the winch 103, and the electric jack 2 are all electrically connected to the external power supply through the control panel.

[0035] Working principle: First, the staff pushes the device to move to the steel coil, then removes the fixing bolts between the lifting frame 1 and the slide plate 2011, pulls the connecting frame 201, and the torque motor of the winch 103 drives the matching wire rope reel to unwind, and then pushes the device so that the steel coil is between the two connecting frames 201. Then the staff pushes the connecting frame 201 to one end of the steel coil, so that the connecting column 202 passes through the center hole of the steel coil, and the two arc-shaped clamping plates 2021 are tightly clamped on both sides of the inner wall of the steel coil under the elastic action of the spring telescopic rod, fixing the connecting column 202 inside the steel coil, and then pushes the connecting column 202 on one side of the other connecting frame 201 to the other end of the center hole of the steel coil, and fixes the lifting frame 1 and the slide plate through the fixing bolts. The plate 2011 is fixed so that the two connecting frames 201 are tightly clamped at the two ends of the steel coil respectively, and the steel coil is fixed between the two connecting frames 201. The torque motor of the hoist 103 drives the matching wire rope reel to slightly reel up, and tightens the wire rope between the hoist 103 and the connecting frame 201. The wire rope provides an upward pulling force for the connecting frame 201. The pulling force provided by the wire rope balances the gravity of part of the steel coil, avoiding that all the gravity of the steel coil is applied to the slide plate 2011, causing the slide plate 2011 to break and damage. The support plate 2012 provides an upward supporting force for the hoisting frame 1, avoiding that all the gravity of the hoisting frame 1 is applied to the slide plate 2011, causing the slide plate 2011 to break and damage, making the connecting frame 201 stronger. , then the electric jack 2 extends, and the connecting frame 201, the lifting frame 1 and the steel coil are simultaneously moved up a distance, so that the steel coil is off the ground, and the electric cylinder 1021 extends, pushing the two arc-shaped plates of the clamp 102 to clamp the two sides of the steel coil. Then the staff assists in rotating the two reinforcement plates 104, and tightens the binding belts 1041 of the two reinforcement plates 104 together through the rope tightener. The connecting plate 1042 is pressed on the lower surface of the steel coil under the action of elastic force. The clamp 102, the reinforcement plate 104 and the binding belt 1041 together form an annular clamp to clamp the steel coil, thereby strengthening the fixing effect of the steel coil. Finally, the external crane matching hook is hung on the lifting ring 101, and the entire device and the steel coil are hoisted into the transport compartment, and the steel coil is adjusted to fall. After the direction is changed, the electric jack 2 continues to extend so that the bottom of the electric jack 2 is supported in the carriage of the transport vehicle, and the connecting frame 201, the lifting frame 1 and the steel coil are positioned to prevent the connecting frame 201, the lifting frame 1 and the steel coil from shaking with the crane rope. Then the two binding belts 1041 are untied, and the electric cylinder 1021 contracts to drive the clamp 102 to separate from the steel coil. Then the electric jack 2 contracts to make the steel coil fall into the carriage, and the fixing bolts between the lifting frame 1 and the slide plate 2011 are removed. The winch 103 is equipped with a wire rope reel and unwinding, and the connecting frame 201 is pulled to move the connecting column 202 and the arc-shaped clamp 2021 out of the center hole of the steel coil. The crane lifts the device out of the carriage to complete the loading of the steel coil.
