Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic hanging beams, and more specifically, to an electromagnetic hanging beam for hoisting steel strip coils. Background Art

[0002] With the improvement of the steel strip coil production line in the steel mill and the increasing degree of automation, the production efficiency of the production line for steel strip coils has been gradually improved. However, when the crane transfers the steel strip coils, only one steel strip coil can be hoisted in each round-trip cycle, and the hoisting efficiency has always been relatively low. The steel strip coils at the end of the production line cannot be hoisted to the steel strip coil stacking area in a timely and effective manner.

[0003] At the end of the steel strip coil production line, as each steel strip coil is packed, there is a certain gap between the packed steel strip coils due to the production line rhythm process. After being transferred to the warehouse, it is necessary to eliminate the gap between the steel strip coils as much as possible and arrange them densely to effectively utilize the storage space.

[0004] Generally, steel strip coils are used in combination with a crane with a clamp or an electromagnetic crane, and only one steel strip coil can be lifted each time. That is, only one steel strip coil can be hoisted in one round-trip cycle of the crane from the production line to the stacking warehouse. When hoisting two or more steel strip coils each time, an electromagnetic hanging beam is required to suspend the electromagnetic crane. The distance between the steel strip coils is relatively large at the end of the production line, which seriously affects the utilization rate of the warehouse after being transferred to the warehouse.

[0005] Compared with the traditional hanging method, the existing electromagnetic lifting tools have been greatly improved, not only increasing the hoisting efficiency, but also greatly improving the safety when hoisting steel strip coils. However, the existing electromagnetic lifting tools still have technical problems such as low hoisting efficiency, insufficient utilization of storage space, and large impact load of the electromagnetic hanging beam, resulting in insufficient safety and stability. Summary of the Utility Model

[0006] In view of the above technical problems in the related art, the present utility model provides an electromagnetic hanging beam for hoisting steel strip coils, which can overcome the above-mentioned deficiencies of the prior art.

[0007] To achieve the above technical purpose, the technical solution of the present utility model is realized as follows:

[0009] The electromagnetic hanging beam for hoisting steel strip coils includes a main beam connected to a lifting chain. A driving mechanism is provided on one side of the main beam. Two moving hanging mechanisms are symmetrically arranged on the left and right below the main beam. Limiting devices are provided on both sides of the two moving hanging mechanisms, and the limiting devices are arranged below the main beam; the main beam includes a main beam support, a gear reversing system, and a roller chain conversion system; the driving mechanism includes a motor, a reducer, and a mounting seat; the driving mechanism drives the two moving hanging mechanisms to move synchronously towards each other or in opposite directions through the gear reversing system and the roller chain conversion system.

[0010] Further, bearing seats are fixedly provided on both sides of the main beam support, and lifting lugs for connecting with the lifting chain are provided above the main beam support.

[0011] Further, the driving mechanism is connected to a main shaft of the main beam. A pair of bearings are provided on the main shaft. The driving mechanism drives the gear reversing system through the main shaft to convert the input single-direction torque into two opposite torques.

[0012] Further, the gear reversing system includes a pair of gears with the same number of teeth. The gears convert the rotation direction input by the reducer of the driving mechanism into two opposite rotation directions for output. The roller chain conversion system first transmits the angular velocities of the two gears to the sprockets, and then converts the two opposite angular velocities into linear velocities through the sprocket chains, so as to drive the moving hanging mechanisms to move synchronously towards each other or in opposite directions and reciprocate below the main beam.

[0013] Further, the moving hanging mechanism is a moving hanging point of the electromagnetic hanging beam. The moving hanging mechanism includes a moving pin shaft, moving rollers, and a hanging main body. The hook of the hanging main body is used to hang an electromagnetic chuck. A pull rod is installed in the hole on the moving pin shaft. The pull rod is connected to the roller chain and drives the hanging beam to move below the main beam.

[0014] Further, the moving rollers are evenly distributed between the main beams and bear the gravity of the hanging beam and the suspended steel strip coils. The moving pin shaft is used to transmit the tension generated during the horizontal movement of the chain to the pull rod of the hanging beam.

[0015] Further, the limiting device includes a mechanical limiting bumper and a travel limiting switch.

[0016] The beneficial effects of the present utility model: Through the optimized and improved design of the product of the present utility model, the electromagnetic hanging beam for hoisting steel strip coils, compared with the traditional hanging method, greatly improves the safety during the hoisting of steel strip coils, effectively improves the hoisting efficiency, and further achieves not only facilitating manual management, but also making it possible to intelligentize and unmannedize the hoisting process of steel strip coils; at the same time, it strengthens the working performance of the electromagnetic hanging beam and expands the application range of the electromagnetic hanging beam.
