Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1 and 2, a ball mill trunnion bush hoisting structure comprises a C-shaped hanger 1 and a trunnion bush 2, wherein the C-shaped hanger 1 is sequentially a bottom beam 102, a side beam 101 and a top beam 103 from bottom to top, and the bottom beam 102 penetrates through the trunnion bush 2 and is used for hoisting the trunnion bush 2. The lower end of the bottom beam 102 is provided with an adjustable supporting mechanism 3 for reducing the shaking amplitude of the trunnion bush 2 in the hoisting process. Adjustable supporting mechanism 3 includes connecting piece 301, adjusts pole 302, connecting piece 301 is the T type structure that a vertical steel pipe and a horizontal steel pipe welding formed, the upper end welding of vertical steel pipe has a steel sheet, steel sheet and floorbar 102 bolted connection, adjust the pole 302 level and set up the both sides at the horizontal steel pipe of connecting piece 301, the regulation pole 302 of both sides supports tightly the inner wall of trunnion bush 2 respectively, restricts rocking of trunnion bush 2 in the hoist and mount in-process. In order to facilitate the adaptation to different sizes of trunnion bushings 2, said adjustment rod 302 is slidably connected to the connection member 301 in order to control the adjustment rod 302 better against the inner wall of the trunnion bushing 2. The adjusting rod 302 and the connecting piece 301 have two sliding connection modes, one mode is that an internal thread is arranged inside the transverse steel pipe of the connecting piece 301, an external thread is arranged on the adjusting rod 302, and the position of the adjusting rod 302 is adjusted by screwing in or screwing out the adjusting rod 302. The other is that a plurality of positioning holes 304 are arranged on the side wall of the transverse steel pipe of the connecting piece 301 in a mirror image mode, a threaded hole 306 is formed in the adjusting rod 302, after the position of the adjusting rod 302 is adjusted, a stud penetrates through the positioning holes 304 and is screwed into the threaded hole 306, the position of the adjusting rod 302 is adjusted, and due to the fact that a plurality of groups of positioning holes 304 and threaded holes 306 are arranged at intervals, the lifting requirements of trunnion bushings 2 of different sizes are met. Referring to fig. 5, the top of the connecting member 301 is also provided with a positioning hole 304 for adjusting the direction of the adjusting rod 302. Referring to fig. 3 and 4, in order to improve the stability of the hoisting process, a supporting plate 303 capable of being attached to the inner wall of the trunnion bush 2 is arranged at one end of the adjusting rod 302 abutting against the trunnion bush 2, so as to improve the contact area between the adjusting rod 302 and the inner wall of the trunnion bush 2, and the shape of the supporting plate 303 is adjusted according to the shape of the contact surface with the inner wall of the trunnion bush 2, and can be a plane or an arc surface. Meanwhile, the anti-skidding rubber plates are arranged on the outer wall of the supporting plate 303, so that the possibility of skidding of a contact surface in the hoisting process is reduced, and the hoisting stability is improved. Because trunnion bush 2's weight is great, adjust the pole 302 and be connected comparatively weak with backup pad 303, consequently increase floor 305 between adjusting pole 302 and backup pad 303 to improve the support intensity of this structure, ensure the security and the stability of hoist and mount, reduce backup pad 303 at the cracked possibility of hoist and mount process.

The bottom beam 102 is detachably connected with the adjustable supporting mechanism 3. The bottom beam 102 is connected with the connecting piece 301 of the adjustable supporting mechanism 3 through bolts, so that the disassembly and the replacement are more convenient. The side beam 101 of the C-shaped lifting appliance 1 is provided with a plurality of hollow cylindrical steel plates 1011, and the hollow cylindrical steel plates 1011 can be arranged on the side walls of the two sides of the side beam 101 in parallel or can penetrate through the wall of the side beam 101 as shown in fig. 1 and 2. In hoist and mount process, constructor's accessible is connected the rope on hollow cylinder steel sheet 1011, rocks the taut rope in the opposite direction through rocking the rope toward hoist and mount and prevents to rock by a wide margin among the hoist and mount process, restricts its degree of freedom. The stability in the hoisting process is improved, and the amplitude of the front and back shaking is reduced.
