Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of smelting equipment and relates to a double-groove rope pulley device for charging a blast furnace skip. Background Art
[0002] In the blast furnace skip system of the smelting industry, the double-groove rope pulley, as a core component, plays a crucial role. This device realizes the stable transportation of materials by skillfully hanging two steel ropes. However, in the actual application process, the double-groove rope pulley and its supporting steel ropes face various challenges, which not only affect the production efficiency but also pose a potential threat to operation safety.
[0003] The primary problem lies in the deformation and relaxation of the steel ropes. During the material transportation process of the blast furnace skip, the steel ropes need to bear huge tensile forces, and this continuous mechanical action can easily cause them to deform, thereby leading to tensile relaxation. The loose steel ropes not only reduce the transportation efficiency but also may cause safety hazards such as material spillage due to insufficient tension.
[0004] Secondly, the friction problem between the steel ropes and the rope grooves cannot be ignored. During long-term use, intense friction will occur between the steel ropes and the rope grooves of the double-groove rope pulley. This friction not only accelerates the wear of the steel ropes but also may cause damage to the rope grooves, thereby triggering serious accidents such as steel rope fracture. Once the steel rope breaks, it will not only cause the interruption of material transportation but also may cause serious harm to the surrounding personnel and equipment.
[0005] Furthermore, there are also significant deficiencies in the maintenance of the traditional double-groove rope pulley for charging a blast furnace skip. When some components of the double-groove rope pulley need to be replaced due to wear or damage, the entire double-groove rope pulley often needs to be disassembled and replaced as a whole. This approach not only increases the difficulty and cost of maintenance but also results in the waste of components that are not damaged or only slightly worn, which runs counter to the current social concept of energy conservation, emission reduction, and efficient utilization of resources. Content of the Utility Model
[0006] In view of this, the purpose of the utility model is to provide a double-groove rope pulley device for charging a blast furnace skip, which solves the defect that when some components of the traditional double-groove rope pulley for charging a blast furnace skip are damaged or worn, it is impossible to only replace the worn or damaged components; and the problem that when the steel rope breaks due to easy tensile relaxation and running wear after being stressed, it cannot be sensed, thus leading to accidents.
[0007] To achieve the above object, the present utility model provides the following technical solution: A double-groove rope pulley device for charging a blast furnace skip, comprising a hub, a first spoke, a second spoke, a rim and a steel wire rope. Among them, the first spoke and the second spoke are connected to the hub by bolts, and the rim is connected to the first spoke and the second spoke by bolts; the steel wire rope is wound around the rim, and an induction steel wire rope is further provided below the steel wire rope and below the rope outlet point of the rim; the end of the induction steel wire rope is connected with an induction body, and the induction body contacts a travel switch; the induction body can move in the vertical direction, and the travel switch issues corresponding signals by judging whether it contacts the induction body.
[0008] Optionally, bolt holes for connecting with the first spoke and the second spoke are provided on the hub. The design of the bolt holes enables the spokes to be firmly connected to the hub, and at the same time facilitates disassembly and replacement.
[0009] Optionally, bolt holes for connecting with the first spoke and the second spoke are provided on the rim. The bolt holes ensure a firm connection between the rim and the spokes, and are convenient for maintenance and replacement.
[0010] Optionally, the first spoke and the second spoke are symmetrically arranged on both sides of the center of the rim respectively. The symmetrical design enhances the structural stability and load-bearing capacity of the wheel.
[0011] Optionally, the front end of the induction steel wire rope is horizontally arranged directly below the steel wire rope and adjacent to the rope outlet point of the steel wire rope, so as to timely detect the slack or breakage of the steel wire rope.
[0012] Optionally, the front end of the induction steel wire rope is fixed, and the rear end forms an L shape after passing through a pulley, and the induction body is connected to the end of the vertical section of the induction steel wire rope.
[0013] Optionally, the travel switch and the induction body are vertically arranged, and the end of the induction steel wire rope is fixedly connected to the induction body, ensuring that when the steel wire rope is slack or broken, the induction steel wire rope can accurately transmit force to the induction body, thereby triggering the travel switch.
[0014] The beneficial effects of the present utility model are as follows: The structure of the present utility model is reasonable, and the components can be reused. At the same time, the reliability and safety of the equipment are improved, and it is an ideal structure for the double-groove rope pulley of the blast furnace skip charging.

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.
[0023] Please refer to Figures 1 to 2, showing an innovatively designed double-groove sheave device for blast furnace charging car. The core structure of the device includes a hub 1, which is tightly connected to spoke 1 2 and spoke 2 3 by strong bolts, ensuring the stability and load-bearing capacity of the structure. Spoke 1 2 and spoke 2 3 are symmetrically distributed on both sides of the rim 4. This symmetrical design not only improves the balance of the wheel, but also helps to disperse the force and extend the service life. The rim 4 is also firmly connected to the spoke 1 2 and spoke 2 3 by bolts, forming a solid frame of the entire sheave device.
[0024] Below the rope exit point of the wheel rim 4, the induction wire rope 6 is cleverly arranged. It is located below the wire rope 5, forming a safety monitoring defense line. The induction wire rope 6 is closely connected to the induction body 7, and the induction body 7 is in contact with the travel switch 8, forming a sensitive monitoring system.
[0025] In this embodiment, the front end of the sensing wire rope 6 is horizontally arranged directly below the wire rope and close to the rope outlet point of the wire rope 5, so as to timely sense the slackness or breakage of the wire rope 5 (that is, the sensing wire rope 6 can catch the slack or broken wire rope 5). The front end of the sensing wire rope 6 is fixed, and the rear end forms an L shape after passing through the pulley. The sensing body 7 is connected to the end of the vertical section of the sensing wire rope 6, the travel switch 8 is vertically arranged with the sensing body 7, and the end of the sensing wire rope 6 is fixedly connected with the sensing body, ensuring that when the wire rope 5 is slack or broken, the sensing wire rope 6 can accurately transmit force to the sensing body 7, thereby triggering the travel switch 8.
[0026] The working principle of the utility model is simple and efficient: when the steel wire rope 5 falls in the direction of the rope exit point due to slack or breakage, due to the effect of gravity, the steel wire rope 5 will directly act on the induction steel wire rope 6, causing the induction steel wire rope 6 to deform. This deformation then drives the induction body 7 connected thereto to move upward, causing it to break contact with the travel switch 8. The travel switch 8 then responds and immediately outputs a stop signal to stop the device, thereby effectively preventing safety accidents caused by problems with the steel wire rope.
[0027] In addition, the device of the utility model has a significant advantage in terms of maintenance. When some parts of the device are damaged or worn, there is no need to replace the entire device, but only to replace the damaged parts in a targeted manner. This design not only reduces maintenance costs, but also improves the utilization rate of parts and reduces resource waste.
[0028] To sum up, the double-groove rope pulley device for charging a blast furnace charge car of the utility model has become an ideal solution for charging a blast furnace charge car with its simple and practical implementation method, convenient operation experience, reduced equipment cost, and improved component utilization rate and equipment reliability and safety.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and all of them should be covered by the scope of the claims of the present invention.
