[0043] The telescopic positioning support assembly 5 includes a telescopic chute 505 opened at the end of the second guide rail 3. An electric telescopic rod 502 is fixedly arranged in the telescopic chute 505. The push rod head end of the electric telescopic rod 502 passes through the telescopic chute 505 and is fixedly connected with an abutting head 501. Support guide blocks 506 are fixedly arranged on the upper and lower sides of the end of the second guide rail 3.

The lower end of the clamping rod 703a is fixedly provided with a first motor 704b for driving the lower hanging rod 704a to rotate. A connecting rod 704c is rotatably and slidably arranged between the two lower hanging rods 704a. The two ends of the connecting rod 704c are fixedly connected to the second limit block 704d. The second limit block 704d can realize The connecting rod 704c is limited in sliding between the two lower suspension rods 704a to prevent the connecting rod 704c from falling off. A plug post 704e is fixedly provided near one side of the bottom end of the two lower suspension rods 704a.

When it is necessary to cooperate with the connecting plate 707 to realize the suspension and fixation of the first electric hoist 4, the first motor 704b drives the lower suspension rod 704a to rotate, so that the plug column 704e is located at the lowest position, and under the drive of the dual-axis electric push rod 702, the plug column 704e is inserted into the slot 706. When there is no need to fix the position of the first electric hoist 4, the first motor 704b drives the lower suspension rod 704a to rotate to a horizontal position, so that the lower suspension rod 704a can be separated from the first electric hoist 4.

[0048] See the instructions attached Figure 4As shown in the figure, a second motor 8 is fixedly installed inside the walking vehicle 2.

The output end of the PLC controller 10 is electrically connected to the input end of the second motor 8. In practical applications, the rotation of the output shaft of the second motor 8 can drive the second guide rail 3 to rotate to the required angle, and with the cooperation of the first electric hoist 4 and the auxiliary hanging assembly 6, the hoisting area range can be expanded.

[0049] Working principle:

[0050] The walking vehicle 2 moves on the first guide rail 1 to facilitate hoisting at any position along the layout direction of the first guide rail 1, and the monitoring cameras 9 provided at both ends of the second guide rail 3 can also be used for patrol monitoring along the layout direction of the first guide rail 1; when hoisting is required, the walking vehicle 2 moves on the first guide rail 1 to the position where hoisting is needed, and then the upper fixing hanging structure 703 of the fixing hanging assembly 7 is used to fix the position between the walking vehicle 2 and the first guide rail 1; the rotation of the output shaft of the second motor 8 drives the second guide rail 3 to rotate by a certain angle, thereby adjusting the angle between the second guide rail 3 and the first guide rail 1. After the rotation adjustment, when there are walls on both sides of the first guide rail 1, the abutting head 501 of the telescopic positioning support assembly 5 extends under the push of the push rod of the electric telescopic rod 502 to achieve the abutment of the abutting head 501 with the external wall, thereby realizing auxiliary support and greatly increasing the bearing capacity of the lifting weight. The first electric hoist 4 and the auxiliary hanging assembly 6 can move along the second guide rail 3, thereby expanding the hoisting range, and the cooperation of the first electric hoist 4 and the auxiliary hanging assembly 6 can realize the cooperation of the hoisted workpiece, greatly improving the stability of the hoisted workpiece; when the first electric hoist 4 is directly below the walking vehicle 2 and the second guide rail 3 is perpendicular to the first guide rail 1 at a right angle, the fixing hanging assembly 7 can also realize the hanging and position fixing with the first electric hoist 4 through the lower positioning hanging structure 704, enabling it to bear a greater hoisting weight.
