The specific working principle is as follows: referring to fig. 1 to 8, the support frame 10 is fixedly installed in place, in an initial state, a gap is formed between the first rope pulley 12 and the second rope pulley 13, ropes 30 on the first rope pulley 12 and the second rope pulley 13 are not mutually extruded, then the first motor 41 is controlled to drive the installation plate 21 to rotate anticlockwise by a certain angle, so that the ropes 30 are unfolded in the annular piece 112, the lifting hook 141 moves downwards and approaches to a first article to be lifted, and in the process, the third rope portion 33 and the movable pulley 14 do not move relatively; next, the hook 141 is hooked on the first article to be hoisted, and then the first motor 41 is controlled to drive the mounting plate 21 to rotate clockwise, in the process, the rope 30 can be gradually wound on the outer sides of the two guide members 22, that is, the rope 30 is gradually stored into the annular member 112, so that the two ends of the third rope portion 33 hung on the movable pulley 14 can simultaneously lift the movable pulley 14 upwards, and the first article is hoisted to a designated height, and in the process, the third rope portion 33 and the movable pulley 14 do not move relatively.
When the first article needs to be lowered to the designated position, the hydraulic cylinder 42 is controlled to drive the second rope sheave 13 to move away from the first rope sheave 12, the rope 30 wound on the second rope sheave 13 is extruded with the inner side surface of the mounting notch, the second rope portion 32 in the rope 30 is in a stopped moving state, the first motor 41 is controlled to drive the mounting plate 21 to rotate anticlockwise, the rope 30 wound on the outer sides of the two guide members 22 is released in the process, one end of the fourth rope portion 34, which is close to the first through hole 113, extends outwards from the first through hole 113 under the auxiliary action of the gravity of the first article, in the process, the second rope sheave 13 stops rotating, the first rope sheave 12 rotates, the first article is lowered, the movable pulley 14 and the third rope portion 33 move relatively, and the abrasion position of the movable pulley 14 to the rope 30 continuously changes.
It will be appreciated that the lifting speed of the process is relatively high, since the two ends of the third rope portion 33 simultaneously lift the travelling block 14 upwards when lifting item one upwards; only one end of the third rope portion 33 is moving during lowering of item number one, thus making the lowering speed of the process slower, and thus achieving a relatively stable lowering of items.
When the article II is required to be hoisted, firstly, the hydraulic cylinder 42 is controlled to drive the second rope pulley 13 to move towards the direction close to the first rope pulley 12 and not to contact with the first rope pulley 12, so that the rope 30 wound on the second rope pulley 13 is restored to move, then, the first motor 41 is controlled to drive the mounting plate 21 to rotate anticlockwise by a certain angle, so that the rope 30 is unfolded in the annular piece 112, so that the lifting hook 141 moves downwards and is close to the article II to be hoisted, and in the process, the third rope portion 33 and the movable pulley 14 do not move relatively; next, the hook 141 is hooked on the second article to be hoisted, and then the first motor 41 is controlled to drive the mounting plate 21 to rotate clockwise, in the process, the rope 30 can be gradually wound on the outer sides of the two guide members 22, that is, the rope 30 is gradually stored in the annular member 112, so that the two ends of the third rope portion 33 hung on the movable pulley 14 can simultaneously lift the movable pulley 14 upwards, so that the second article is hoisted to a designated height, and in the process, the third rope portion 33 and the movable pulley 14 do not move relatively.
When the second article needs to be lowered to the designated position, the hydraulic cylinder 42 is controlled to drive the second rope sheave 13 to move away from the first rope sheave 12, the rope 30 wound on the second rope sheave 13 is extruded with the inner side surface of the mounting notch, the second rope portion 32 in the rope 30 is in a stopped moving state, the first motor 41 is controlled to drive the mounting plate 21 to rotate anticlockwise, the rope 30 wound on the outer sides of the two guide members 22 is released in the process, one end of the fourth rope portion 34, which is close to the first through hole 113, extends outwards from the first through hole 113 under the auxiliary action of the gravity of the second article, in the process, the second rope sheave 13 stops rotating, the first rope sheave 12 rotates, the second article is lowered, the movable pulley 14 and the third rope portion 33 move relatively, and the abrasion part of the movable pulley 14 to the rope 30 continuously changes in the process.
Through the hoisting of the first article and the second article, the following conclusion can be drawn: the wearing position of the movable pulley 14 on the rope 30 is continuously changed, so that the continuous wearing of a certain part of the rope 30 is avoided, and the rope 30 can be circularly worn, thereby being beneficial to prolonging the service life of the rope 30.
