Description

Technical Field

[0001] The utility model relates to the technical field of preheater processing, in particular to a liftable rack used for preassembling hanging pieces of a preheater inner cylinder. Background Art

[0002] The preheater inner cylinder hanging plate is an important component of the preheater, playing a role in heat resistance and wear resistance. After the hanging plate is processed and formed, it needs to be pre-assembled to check whether it is suitable for the requirements of the preheater inner cylinder.

[0003] The pre-assembly of the hanging pieces is accomplished on a hanging rack. Existing hanging racks have a relatively simple structure and function, consisting of a welded circular frame with a ring of hanging rings at the top. To mimic the preheater inner cylinder, the hanging rack must be designed to be taller. Assembly of the hanging pieces requires the use of a mobile platform, requiring a human operator to stand on the platform and rotate the hanging piece from a high point. After several rotations, the platform is lowered and the hanging piece is re-installed, repeating this process. This is time-consuming and labor-intensive. Therefore, the present invention proposes a liftable hanging rack for pre-assembly of hanging pieces for the preheater inner cylinder to address the shortcomings of the existing technology.

A movable groove 4 is provided on the vertical cylinder 2, and the movable groove 4 is provided with multiple groups. A through groove 5 is provided on the vertical cylinder 2 on the rear side of the multiple groups of movable grooves 4. The through groove 5 is connected with the movable groove 4. A movable seat 6 is movably provided in the movable groove 4, and a hanging ring 8 is provided on the movable seat 6; the central rotating seat includes a central platform 9 and a rotating ring 10, a rotating ring 10 is movably provided on the outer side of the central platform 9, and a driving mechanism is provided on the top of the central platform 9, which drives the rotating ring 10 to rotate on the outer wall of the central platform 9, and a lifting mechanism 3 is provided on the top of the rotating ring 10, a magnetic arm 11 is installed on the lifting mechanism 3, and a magnetic seat 12 adapted to the magnetic arm 11 is provided on the top of the movable seat 6.

[0024] When the preheater inner cylinder hanging piece pre-assembled liftable hanger of the present invention is used, the magnetic arm 11 on the lifting mechanism 3 is moved above the corresponding through slot 5 by controlling the rotation of the central swivel seat. Then, the magnetic arm 11 on the lifting mechanism 3 is lowered and enters the through slot 5, and is magnetically fixed to the magnetic seat 12 on the movable seat 6 below. Then, the magnetic arm 11 is raised on the lifting mechanism 3 to drive the movable seat 6 to rise. The operator can hang the hanging piece on the hanging ring 8 on the movable seat 6 from a low position, and can hang multiple hanging pieces by continuously raising the position. When hanging pieces on the movable seats 6 in multiple movable slots 4, the above operation can be repeated by controlling the lifting mechanism 3 to move to different positions.

[0025] The movable seat 6 includes a first round rod 601 and a second round rod 602 . The outer wall of the first round rod 601 is slidably connected to the movable groove 4 , and the second round rod 602 is arranged at the front side of the lower end of the first round rod 601 .

[0026] The upper inner wall of the movable groove 4 is provided with a mounting hole, in which an automatic fixing pin 13 is installed. The side wall of the first round rod 601 is provided with a fixing hole 7 that is compatible with the automatic fixing pin 13. In the present utility model, when the movable seat 6 is raised to a high position under the control of the lifting mechanism 3 and needs to be fixed in position, the position of the movable seat 6 is fixed by controlling the automatic fixing pin 13 to extend into the fixing hole 7.

[0027] The driving mechanism includes a gear ring 14, a gear 15, and a first motor 16. The upper end of the slewing ring 10 extends beyond the top of the center platform 9, and the gear ring 14 is provided on the inner side wall.

By starting the first motor 16, the rotating shaft can be driven to rotate. The gear 15 installed on the rotating shaft drives the slewing ring 10 installed with the gear ring 14 to rotate on the center platform 9, thereby driving the lifting mechanism 3 installed on the top of the slewing ring 10 to rotate.

[0028] The lifting mechanism 3 includes a bracket 301, a screw 302, and a sleeve 303. The bracket 301 is mounted on the top of the slewing ring 10. The bracket 301 has a screw 302 rotatably mounted therein. The sleeve 303 is threadedly connected to the screw 302. The sleeve 303 is slidably connected to the bracket 301. The screw 302 is driven by a second motor. When the second motor is activated to rotate the screw 302, the sleeve 303 is raised and lowered synchronously on the screw 302 and the bracket 301.

[0029] The magnetic arm 11 includes a connecting rod 1101 and a magnetic block 1102. One end of the connecting rod 1101 is connected to the outer wall of the sleeve 303. The cross-sectional size of the connecting rod 1101 is smaller than the cross-sectional size of the through groove 5. The magnetic block 1102 is concentrically arranged with the magnetic seat 12 in the longitudinal direction, and the magnetic block 1102 is installed at one end of the connecting rod 1101.

[0030] The utility model sets a central rotating seat at the center of the top of the base 1, and then sets a vertical cylinder 2 on the top of the base 1 outside the central rotating seat. The movable seat 6 set in the movable groove 4 on the vertical cylinder 2 can be controlled to rise and fall by the lifting mechanism 3 set on the top of the central rotating seat. The lifting movable seat 6 can facilitate the operator to hang and assemble the preheater inner cylinder hanging piece from a low position. One set of lifting mechanisms 3 can control multiple groups of movable seats 6 to rise and fall from multiple positions. The structure has the advantages of being simple and easy to operate. After the hanger is used, the hanging efficiency of the preheater inner cylinder hanging piece can be greatly improved.
