Description

Technical Field

[0001] The utility model relates to cold-rolled steel coil production equipment, in particular to a lifting device in steel coil production, belonging to the technical field of cold-rolled steel bar production equipment. Background Art

[0002] In the production of cold-rolled steel coils (coils), after the coiling station completes the coiling, a transport trolley is used to transport the steel coil. The holes of the steel coil are placed flat on the transport trolley in the up and down directions. The transport trolley is fixedly connected with a mandrel, which is located in the hole of the steel coil. The transport trolley travels on a roller-driven track (steel coil conveyor line) (the roller is driven by a motor, and the roller drives the transport trolley to travel). The commonly used track is composed of multiple identical track units, so that the track can be flexibly extended or shortened as needed. There is a right-angle turner at the 90-degree turn of the track. Under certain specific conditions (such as factory buildings), The height and plane are limited in one direction). In the process of transporting steel coils by transporting carts, it is necessary to lift (or lower) from one height to another. Currently, a door-type structure elevator is used to meet this demand. This door-type structure elevator is symmetrically arranged on both sides of the steel coil conveyor line. This elevator has a large load-bearing capacity but at the same time its structure is relatively complex, the cost is high, the area is large, and strict synchronization is required on both sides during operation. In the field of cold-rolled wire production technology, since the steel coil weighs about 2 tons and the load is light, the elevator using this door-type structure is not cost-effective. Summary of the invention

[0003] The purpose of the utility model is to overcome the above-mentioned problems existing in the lifting equipment in the current steel coil production and to provide a lifting device in the steel coil production.

[0004] To achieve the purpose of the utility model, the following technical scheme is adopted: a lifting device in steel coil production, including a stand fixedly installed on one side of a track unit, the cylinder body of the oil cylinder is hinged on the stand, two guide rails in the upper and lower directions are fixedly installed on the stand, a slider is slidably installed on the guide rail, a lifting platform is fixedly connected to the slider, the track unit is located on the lifting platform, a sprocket is rotatably installed on the upper end of the cylinder rod of the oil cylinder, a chain is fitted on the sprocket, one end of the chain is fixedly connected to the lifting platform, and the other end is fixedly connected to the stand.

[0005] Furthermore, a set of clamping mechanisms are respectively installed on the front and rear of the lifting platform, and the clamping mechanism includes a clamping plate, which is hinged to the lifting platform through a vertical axis. The hinged part between the clamping plate and the lifting platform deviates from the end of the clamping plate, and the inner end of the clamping plate is hinged to the cylinder rod of the clamping hydraulic cylinder, and the cylinder body of the clamping hydraulic cylinder is hinged to the lifting platform.

[0006] Furthermore, a baffle is fixedly connected to the front and rear of the stand, the height of the baffle is lower than the track unit, and the baffle does not interfere with the transport trolley entering the track unit.

[0007] The positive and beneficial technical effects of the utility model are: the device realizes reliable lifting and lowering of the steel coil, has a simple and reliable structure, occupies a small area, and has significantly lower installation and operation costs than existing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 It is a schematic diagram of the front and rear directions of this device.

[0010] Figure 3 It is a top view schematic diagram of the device. DETAILED DESCRIPTION

[0011] In order to more fully explain the implementation of the utility model, implementation examples of the utility model are provided. These implementation examples are only for the purpose of illustrating the utility model and do not limit the scope of the utility model.

[0012] The utility model is further explained in detail in conjunction with the accompanying drawings, in which the marks are: 1: stand; 2: lifting platform; 3: track unit; 4: oil cylinder; 5: sprocket; 6: guide rail; 7: slider; 8: baffle; 9: front clamping plate; 10: front clamping hydraulic cylinder; 11: rear clamping hydraulic cylinder; 12: rear clamping plate; 13: chain

[0013] Figure 1 The middle lifting platform is in a slightly raised state, and the track unit 3 is higher than the track in front. When the lifting platform is in place, the track unit 3 and the track in front are at the same height, and the transport vehicle can enter the track unit 3 on the lifting platform 2. The front and rear of the stand are fixedly connected with baffles 8, which can better position the track unit 3. The height of the baffle 8 is lower than the track unit 3, and there is no interference between the baffle and the transport vehicle entering the track unit.

[0014] The utility model is a lifting device for steel coil production, comprising a stand 1 fixedly mounted on a track unit side, a cylinder body of an oil cylinder 4 hinged on the stand 1, two guide rails 6 in the up-and-down direction fixedly mounted on the stand, a slider 7 slidably mounted on the guide rail 6, a lifting platform 2 fixedly connected to the slider 7, a track unit 3 located on the lifting platform, a sprocket 5 rotatably mounted on the upper end of the cylinder rod of the oil cylinder, a chain 13 matched on the sprocket, one end of the chain 13 fixedly connected to the lifting platform 2, and the other end fixedly connected to the stand 1. When the cylinder rod of the oil cylinder is raised or lowered, the sprocket is driven to rise or fall, and the lifting of the sprocket drives the lifting platform to rise or fall, thereby completing the lifting. During the lifting process, the sprocket rotates, which can reduce friction and make the lifting stable and controllable.

[0015] As a further optimization of the device, a set of clamping mechanisms are installed at the front and back of one side of the lifting platform. The clamping mechanism includes a clamping plate, which is hinged to the lifting platform through a vertical axis. The hinged portion between the clamping plate and the lifting platform deviates from the end of the clamping plate. The inner end of the clamping plate is hinged to the cylinder rod of the clamping hydraulic cylinder, and the cylinder body of the clamping hydraulic cylinder is hinged to the lifting platform. The two clamping plates in the figure are the front clamping plate 9 and the rear clamping plate 12. The inner end of the front clamping plate is hinged to the cylinder rod of the front clamping hydraulic cylinder 10, and the inner end of the rear clamping plate is hinged to the cylinder rod of the rear clamping hydraulic cylinder 11. The middle parts of the two clamping plates are hinged to the lifting platform. The clamping hydraulic cylinder drives the clamping plate to press against the transport trolley (not shown in the figure) located on the track unit to prevent it from shifting and falling off.

[0016] The specific action process of the hoist is explained by lifting a steel coil (steel coil) from a low place to a high place:

[0017] In the standby state, the lifting platform is in the low position, the front clamping plate is open, and the rear clamping plate is closed to prevent the trolley transporting the steel coil from escaping the track unit;

[0018] The transport trolley moves from the front track to the track unit 3 on the lifting platform, and the front clamping plate closes to clamp the trolley;

[0019] The oil cylinder moves, the cylinder rod extends, driving the chain to drive the lifting platform to the highest position, the rear clamping plate opens, and the running trolley runs from the track unit to the rear of the highest position;

[0020] After the transport trolley is completely separated from the track unit, the lifting platform moves down to a low position to wait for the next transport trolley, while the front clamping plate opens and the rear clamping plate closes.

[0021] After describing the implementation mode of the utility model in detail, people familiar with the technology can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of the technical solution of the utility model, and the utility model is not limited to the implementation mode of the examples given in the specification.
