Description

Technical Field

[0001] The utility model relates to the field of circular stacker-reclaimers, in particular to a circular stacker-reclaimer with a support-free structure. Background Art

[0002] Circular stacker-reclaimer is an important equipment for transferring coal and iron powder in thermal power plants, coal chemical enterprises and steel mills. It is mainly installed inside circular material yards and can effectively reduce the impact of dust on the surrounding environment. It is currently the most environmentally friendly bulk material conveying equipment.

[0003] The circular stacker-reclaimer is mainly composed of three parts: the center column, the stacker and the reclaimer. The stacker and the reclaimer are independent of each other, that is, they can perform stacking and reclaiming operations at the same time, which improves work efficiency. The power supply of the entire equipment usually adopts a "slip ring" + "support" structure. The power and control cables go straight up along the center column to the cable slip ring on the top, and then come out of the cable slip ring and return to the stacker bridge, pass through the downward support bracket, to the support trolley, and then go down to the reclaimer bracket, enter the bridge of the reclaimer, and finally send it to the reclaimer distribution cabinet in the electrical room of the reclaimer; the upper bracket of the support moves with the stacker, the support trolley is fixed under the platform track in the middle of the center column, and the lower bracket of the support moves with the reclaimer, thereby completing the transition of power from the stacker to the reclaimer.

[0004] At present, during the use of a circular stacker-reclaimer with a support trolley structure, the stacker and the reclaimer need to rotate back and forth to work. The stacker and the reclaimer will drag the support trolley back and forth on the track. The power and control cables laid on the support trolley will be bent repeatedly during long-term work, resulting in frequent core and strand breakage failures in this part laid on the support trolley, making the circular stacker-reclaimer unable to work normally and affecting the production of the user; at the same time, the number of cables in this part is large, and scaffolding needs to be set up to replace the cables, resulting in the inability to quickly replace the cables and eliminate the faults in time during inspection and maintenance. Summary of the invention

[0005] The utility model solves the problem that the existing circular stacker-reclaimer needs to rely on a support structure to complete the transition of power supply from the stacker to the reclaimer, and provides a circular stacker-reclaimer without a support structure. A stacking slip ring mechanism and a reclaiming slip ring mechanism are arranged, and the stacker and the reclaimer are powered separately. The stacker PLC and the reclaimer PLC communicate wirelessly without a support structure, thereby avoiding the occurrence of cable core breakage, cable strand breakage and other faults.

[0006] In order to solve the above problems, the technical solution of the utility model is:

[0007] A circular stacker-reclaimer with a support-free structure, comprising a central column, a stacker and a reclaimer, wherein the stacker is located at the upper end of the central column, a stacking electrical room is provided on the stacker, a stacking machine PLC is provided in the stacking electrical room, the reclaimer is arranged near the lower end of the central column, a driver's cab and a reclaiming electrical room are provided on the reclaimer, a reclaiming machine PLC is provided in the reclaiming electrical room, a stacking slip ring mechanism is provided near the stacking electrical room, the stacking electrical room is connected to a power supply through the stacking slip ring mechanism, a reclaiming slip ring mechanism is provided near the reclaiming electrical room, and the reclaiming electrical room is connected to a power supply through the reclaiming slip ring mechanism;

[0008] The stacker PLC is provided with a wireless module 1 and an antenna 1, and the reclaimer PLC is provided with a wireless communication module 2 and an antenna 2. The stacker PLC is wirelessly connected to the reclaimer PLC. The antenna 1 is arranged outside the stacker electrical room, and the antenna 2 is arranged outside the reclaimer electrical room.

[0009] Furthermore, the stacker includes a belt mechanism, a stacking rotary mechanism and a stacking arm, and the stacker PLC is electrically connected to the belt mechanism and the stacking rotary mechanism;

[0010] The stacking slip ring mechanism includes a slip ring, a power cable, a control cable and an optical fiber cable. The power cable, the control cable and the optical fiber cable enter the stacking electrical room through the slip ring and the stacking arm, and are respectively connected to the belt mechanism, the stacking rotation mechanism and the stacking machine PLC.

[0011] The stacker uses a set of "power + control + optical fiber" three-in-one slip ring to realize the power supply of the stacker.

[0012] Furthermore, a stacking arm counterweight is provided on one side of the stacking arm, and the stacking electrical room and the stacking arm counterweight are provided on the same side;

[0013] The stacking slewing mechanism comprises an upper slewing bearing and a lower slewing bearing, wherein the upper slewing bearing is arranged above the stacking arm, and the lower slewing bearing is arranged below the stacking arm.

[0014] Adding a stacking electrical room on the counterweight side of the stacking arm is equivalent to increasing the weight of the counterweight side. In this way, the original counterweight can be reduced to the same weight as the electrical room, saving counterweight materials.

[0015] Furthermore, the material reclaimer includes a material reclaiming rotating mechanism, a material reclaiming pitching mechanism and a material reclaiming scraper mechanism. The material reclaiming slip ring mechanism is installed above the material reclaiming rotating mechanism. The material reclaiming slip ring mechanism includes a slip ring and a power cable. The power cable enters the material reclaiming electrical room through the slip ring and is respectively connected to the material reclaiming rotating mechanism, the material reclaiming pitching mechanism, the material reclaiming scraper mechanism and the material reclaimer PLC.

[0016] The reclaimer uses a set of "power" slip rings to power the reclaimer.

[0017] Furthermore, the driver's cab includes an operating console, which includes a plurality of buttons and knobs, and the output ends of the buttons and knobs are respectively connected to the input ends of the reclaimer PLC.

[0018] Through the above technical solution, the beneficial effects of the utility model are:

[0019] The utility model eliminates the existing support structure, and no cables are laid between the stacker and the reclaimer. The stacker and the reclaimer are powered independently. A stacking slip ring mechanism and a reclaiming slip ring mechanism are provided. The stacker PLC is provided with a wireless module 1 and an antenna 1, and the reclaimer PLC is provided with a wireless communication module 2 and an antenna 2. The stacker PLC is wirelessly connected with the reclaimer PLC. The antenna 1 is provided outside the stacking electrical room, and the antenna 2 is provided outside the reclaiming electrical room. The wireless communication module is used for wireless communication during communication, thereby realizing power distribution and control signal transmission between the stacker and the reclaimer.
