Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, and more specifically to a lifting component of a mobile production platform. Background Art

[0002] Acheson graphitization furnace is a high-temperature electric furnace used to convert carbonaceous materials into artificial graphite. The design principle of this furnace is to load carbon billets and granular materials into a long furnace body made of refractory materials, which constitute a conductive furnace core.

[0003] Before and after the use of the Acheson graphitization furnace, a support platform will be set up for workers to move. The support platform has multiple uses: 1. It can provide workers with a convenient mobile platform when loading the crucible into the furnace to improve the workers' loading efficiency; 2. After the Acheson graphitization furnace is roasted, the internal residue needs to be cleaned. The support platform can be used to load the cleaned residue to improve the cleaning efficiency; 3. After the Acheson graphitization furnace is used, the internal sensor electrodes need to be maintained to improve the service life of the Acheson graphitization furnace.

[0004] When working inside the furnace, the mobile platform is usually moved by controlling the movement of a wire rope. For example, the Chinese patent with application number 202321039710.6 discloses a boiler furnace maintenance lifting platform, the structure of which includes a top frame, a maintenance platform, a lifting mechanism, an extension platform, and a plurality of first connecting rods. The first connecting rods are arranged at intervals around the maintenance platform. The upper end of each first connecting rod is connected to the top frame, and the lower end of each first connecting rod is connected to the maintenance platform. The lifting mechanism includes a winch and a traction rope. One end of the traction rope is connected to a suspension device preset at the top of the boiler, and the other end of the traction rope is wound around the winch. The maintenance platform includes a bottom frame and a plurality of load-bearing beams. The two ends of the load-bearing beams are respectively connected to two opposite frames of the bottom frame, and the winch is connected to the load-bearing beam. The boiler furnace maintenance lifting platform also has the following problems:

[0005] Since the Acheson graphitization furnace needs to be cleaned after use, a large amount of dust and other particles will be generated during the cleaning. After these dust particles fall on the wire rope, they will not only increase the wear of the wire rope, but also may affect its normal operation and even cause safety accidents. The mobile platform lacks a structure that can clean the dust that falls on the wire rope. At the same time, the platform is supported only by the wire rope on the top. During the movement, it will shake due to the movement of the maintenance personnel, which is not conducive to the safety of the maintenance personnel.

[0006] Therefore, it is necessary to propose a lifting component of a mobile production platform to solve the above problems. Utility Model Content

[0036] The cleaning assembly 110 includes a fixing frame 114, a cleaning bucket 115 and a collecting bucket 116 fixed on the fixing frame 114. The circular cleaning brush 121 inside the cleaning bucket 115 performs a rotational cleaning function on the wire rope 111 to clean off dust particles and the like that fall on the wire rope. The dust particles that fall are blocked by the gear lever 128 and fall into the collecting bucket 116. It should be noted that the wire rope 111 passes through the cleaning assembly 110 and does not come into contact with the upper gear 118, the cleaning bucket 115, the collecting bucket 116 and the connecting column 125, but only comes into contact with the circular cleaning brush 121.

When dust falls on the lower gear 126, it will rotate with it, and will be blocked by the gear lever 128 during the rotation process, thereby falling into the collecting barrel 116 through the drop hole 127. The lower gear 126 is rotatably connected to the outer wall of the connecting column 125, and the lower gear 126 rotates at the bottom of the cleaning barrel 115.

[0042] In this embodiment, traveling tracks parallel to the furnace are installed on both sides of the Acheson graphitization furnace for the movement of the end beam traveling device 102. A reducer is installed on the end beam traveling device 102 to drive the support frame 101 to move, so that the entire equipment can move along the axial direction of the furnace to expand the working area of ​​the operator.

[0043] After the maintenance personnel enter the lifting platform 104, the lifting platform 104 can be moved downward by driving the lifting assembly 103, so that work inside the furnace can be carried out.

[0044] When the furnace is cleaned and the lifting platform 104 is raised, the wire rope 111 needs to be cleaned, and the output end of the driving device 109 drives the drum 113 to rotate. When the drum 113 rotates, the wire rope 111 can be wound around the drum wall, and the other end of the wire rope 111 drives the lifting platform 104 to move upward. When the wire rope 111 passes through the guide assembly 107, it will drive the roller 122 on the guide assembly 107 to rotate, and the roller 122 drives the driving gear 117 to rotate through the transmission assembly 124.

The upper gear 118 drives the planetary gear 119 at the bottom to rotate along the axis. When the planetary gear 119 moves, it will contact the gear ring 120, thereby generating self-rotation, and drive the circular cleaning brush 121 at the bottom to rotate, thereby cleaning the wire rope 111.

[0045] The fallen dust will accumulate on the top of the lower gear 126, and the lower gear 126 will also rotate driven by the active gear 117, thereby driving the accumulated dust to rotate along the axis. When it moves to the position of the gear lever 128, it will be blocked by the gear lever 128, and thus fall from the drop hole 127 to the collection barrel 116 at the bottom. The dust collected in the collection barrel 116 is easy for maintenance personnel to clean.

[0046] One side of the collection barrel 116 is a hinge, and the other side is a buckle, and the collection barrel 116 can be opened by the buckle to clean the inside.
