The part of the eighth wire rope 62 between the third hoist 6 and the second guide roller unit 14 is vertically arranged, and the part of the eighth wire rope 62 between the second guide roller unit 14 and the second guide roller unit 22 is horizontally arranged, so that one eighth wire rope 62 applies a leftward tension to the second installation frame 221 and the other eighth wire rope 62 applies a rightward tension to the second installation frame 221; during the movement of the mounting seat 3, the first winch 4 can retract the seventh wire rope 43, the third winch 6 can retract the eighth wire rope 62, so that the seventh wire rope 43 and the eighth wire rope 62 are always in a tightening state, and the second mounting frame 221, the second guide rope pulley 222 and the third guide rope pulley 223 are kept stable, so that the tightening effect of the sixth wire rope 53 on the mounting seat 3 is ensured.
It should be noted that, the windward area of the second installation frame 221 is smaller, and the second installation frame 221 is not hung with a weight, so that the stability of the second installation frame 221 is further improved.
In this embodiment, two eighth wire ropes 62 are installed on each third hoist 6, and four eighth wire ropes 62 are respectively connected to four corners of the second installation frame 221, so that the second installation frame 221 is further not easy to swing.
The second mounting frame 221 is slidably matched with the mounting seat 3 along the front-back direction of the mounting seat 3, so that the mounting seat 3 is not easy to shake relative to the second mounting frame 221, and further the mounting seat 3 and the lifting appliance 31 are not easy to swing.
In this embodiment, four second guide rods 224 extending along the front-rear direction of the mounting seat 3 are mounted on top of the second mounting frame 221, four second guide rings 33 are mounted on top of the mounting seat 3, the second guide rods 224 and the second guide rings 33 are in one-to-one correspondence, and the second guide rods 224 are slidably embedded in the second guide rings 33 along the front-rear direction of the mounting seat 3, so that sliding fit between the second mounting frame 221 and the mounting seat 3 is achieved.
The working principle of the invention is as follows: when the hanger 31 hangs a heavy object, the first hoist 4 will apply an upward pulling force to the mount 3 through the four first wire ropes 41; the second windlass 5 on the left side of the bracket 1 will apply a left pulling force to the mounting seat 3 through the two second steel wire ropes 51, and the second windlass 5 on the right side of the bracket 1 will apply a right pulling force to the mounting seat 3 through the two second steel wire ropes 51; the first winch 4 will apply an upward tension to the first mounting frame 211 through the two fourth wire ropes 42, the third winch 6 on the left side of the bracket 1 will apply a leftward tension to the first mounting frame 211 through the two fifth wire ropes 61, the third winch 6 on the right side of the bracket 1 will apply a rightward tension to the first mounting frame 211 through the two fifth wire ropes 61, so that the first mounting frame 211 and the first rope guide sheave 212 remain stable, and the second winch 5 will apply a downward tension to the mounting seat 3 through the four wire ropes; the first hoist 4 will apply an upward tension to the second mounting frame 221 through the two seventh wire ropes 43, the third hoist 6 on the left side of the bracket 1 will apply a leftward tension to the second mounting frame 221 through the two eighth wire ropes 62, the third hoist 6 on the right side of the bracket 1 will apply a rightward tension to the second mounting frame 221 through the two eighth wire ropes 62, so that the second mounting frame 221, the second guide sheave 222 and the third guide sheave 223 are kept stable, and both the second hoists 5 will apply a forward tension and a backward tension to the mount 3 through the sixth wire ropes 53.
In the lifting process of the lifting appliance 31, the controller 7 controls the four first windlass 4 to start synchronously, and the first windlass 4 simultaneously receives and releases the first steel wire rope 41, the fourth steel wire rope 42 and the seventh steel wire rope 43, so that the relative stability of the mounting seat 3, the first mounting frame 211 and the second mounting frame 221 is kept unchanged, and the fourth steel wire rope 42 and the seventh steel wire rope 43 are kept in a tightening state so as to ensure the tightening effect of the fourth steel wire rope 42 on the first mounting frame 211 and the tightening effect of the seventh steel wire rope 43 on the second mounting frame 221; the controller 7 also controls the two motors 151 to start, the motors 151 drive the screw rods 153 to rotate through the gear sets 152, and the screw rods 153 drive the lifting seats 154 to move, so that the lifting seats 154 and the mounting seats 3 keep the same height; the controller 7 will also control the two second winches 5 and the two third winches 6 to start, the second winches 5 will simultaneously wind and unwind the second wire rope 51, the third wire rope 52 and the sixth wire rope 53, the third winches 6 will simultaneously wind and unwind the fifth wire rope 61 and the eighth wire rope 62, and the second wire rope 51, the third wire rope 52, the fifth wire rope 61, the sixth wire rope 53 and the eighth wire rope 62 will be kept in a tight state to ensure the tightening effect of the second wire rope 51, the third wire rope 52 and the sixth wire rope 53 on the mount pad 3, the tightening effect of the fifth wire rope 61 on the first mount frame 211 and the tightening effect of the eighth wire rope 62 on the second mount frame 221.
During the movement of the travelling car 2, the controller 7 controls the travelling car 2 to move left and right on the cross beam 11, the controller 7 also controls the second winch 5 and the third winch 6 to start, the second winch 5 simultaneously winds and unwinds the second wire rope 51, the third wire rope 52 and the sixth wire rope 53, the third winch 6 simultaneously winds and unwinds the fifth wire rope 61 and the eighth wire rope 62, and the second wire rope 51, the third wire rope 52, the fifth wire rope 61, the sixth wire rope 53 and the eighth wire rope 62 are kept in a tight state so as to ensure the tensioning effect of the second wire rope 51, the third wire rope 52 and the sixth wire rope 53 on the mounting seat 3, the tensioning effect of the fifth wire rope 61 on the first mounting frame 211 and the tensioning effect of the eighth wire rope 62 on the second mounting frame 221.
Therefore, when the hanger 31 hangs a heavy object, the mount 3 is simultaneously subjected to the tensile forces in the up, down, left, right, forward and backward directions of 6 directions no matter whether the hanger 31 is moved or not, so that the mount 3 is not easy to swing, thereby reducing the swing amplitude of the hanger 31 and shortening the swing duration of the hanger 31.
