[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 9 , the present invention provides a technical solution: a device suitable for installing prefabricated blocks of arched skeletons;

[0034] Example 1:

[0035] In order to remove the oil sludge formed by the mixture of lubricating oil and dust in the slide 18, a slide 18 is provided inside the cross bar 11, and the driving assembly 6 includes: a driving motor 601, a pulley 602 is rotatably installed on the output end of the driving motor 601, and the pulley 602 slides along the inner surface of the slide 18, and the output end of the rotating motor 9 is rotatably connected to the lower surface of the column 10, and a collecting box 603 is fixedly installed on the side wall of the driving motor 601, and a shovel block 604 is fixedly installed on the side surface of the collecting box 603 in a direction perpendicular to the slide 18. The shovel block 604 slides inside the slide 18 by the drive of the driving motor 601, and a chamber 605 is provided inside the shovel block 604, and an inclined block 606 is provided at the bottom of the chamber 605. The side wall of the shovel block 604 is provided with a slot 607, and limit plates 608 are fixedly installed on both sides of the slide 18;

[0036] First, start the drive motor 601 to drive the pulley 602 to slide on the surface of the slide 18, so that the oil, dirt and dust mixture in the slide 18 can be shoveled out through the shovel block 604, and the shoveled oil and dirt mixture is allowed to enter the collection box 603 through the slot 607 through the inclined block 606 at the bottom of the chamber 605 for centralized collection.

[0037] Example 2:

[0038] In order to achieve multiple buffering of the swing generated during the mobile transportation of the hoisting equipment and avoid safety hazards caused by large swings, an anti-sway buffer mechanism 7 is fixedly installed on the lower surface of the driving motor 601. The anti-sway buffer mechanism 7 includes: a mounting frame 701, and a clearance groove 703 for the clearance steel cable 16 is opened at the bottom and top of the mounting frame 701. A dovetail slide rail 702 is fixedly installed on the bottom surface of the mounting frame 701. A counterweight plate 704 and a slider 708 are slidably installed on the outer surface of the dovetail slide rail 702. Two symmetrically arranged sliding rods 713 are fixedly installed on the inner wall of the counterweight plate 704. A limiting sleeve 712 is fixedly installed on the bottom of the slider 708. A spring 714 is sleeved on the slide bar 713 at the connection between the counterweight plate 704 and the slider 708. The bottom end side surfaces of the counterweight plate 704 and the slider 708 are respectively provided with a first dovetail slide groove 705 and a second dovetail slide groove 711 that slide with the dovetail slide rail 702. The inner surface of the slider 708 is provided with an opening 709 corresponding to the slide bar 713. The slider 708 is connected to the slide bar 713 through the opening 709. The counterweight plate 704 and the slider 708 are elastically connected by the spring 714. The counterweight plate 704 and the slider 708 slide on the inner surface of the mounting frame 701 through the sliding cooperation of the first dovetail slide groove 705 and the second dovetail slide groove 711 with the dovetail slide rail 702.

[0039] The counterweight plate 704 and the slider 708 are connected by sliding in the installation frame 701, and the counterweight plate 704 and the slider 708 are elastically connected by a spring 714. A limiting sleeve 712 is provided at the bottom of the through hole 710 in the slider 708. The steel cable 16 passes through the through hole 710 and the limiting sleeve 712 in turn to lift the prefabricated block. When the steel cable 16 swings in the limiting sleeve 712, it will first drive the slider 708 to squeeze the spring 714 on the slide rod 713 through the opening 709. Since the two ends of the spring 714 are elastically connected to the counterweight plate 704 and the slider 708 respectively, the slider 708 will slide repeatedly in the installation frame 701 under the traction of the steel cable 16, thereby being buffered multiple times by the spring 714.

[0040] Example 3:

[0041] In order to enhance the anti-sway effect of the anti-sway buffer mechanism 7 based on the second embodiment, the steel cable 16 is driven by the driving motor 601 to pass through the through hole 710 and the limiting sleeve 712 in sequence, and a bolt 706 is threadedly installed on the side wall of the counterweight plate 704, and a nut 707 is threadedly connected to the outer surface of the bolt 706;

[0042] First, the swing amplitude of the steel cable 16 is initially limited by the limiting sleeve 712. Since the counterweight plate 704 and the slider 708 are elastically connected by the spring 714, hard contact with the swing amplitude of the steel cable 16 is avoided. Compared with the fixed connection, the wear of the steel cable 16 can be reduced. Through the threaded connection between the side wall bolt 706 of the counterweight plate 704 and the nut 707, the counterweight plate 704 can be installed according to the weight of the hoisted prefabricated block to enhance the anti-sway effect of the steel cable 16.

[0043] Working principle: In actual use, when cleaning the oil sludge formed by the mixture of lubricating oil and dust in the slide 18, first start the driving motor 601 to drive the pulley 602 to slide on the surface of the slide 18, so that the oil and dust mixture in the slide 18 can be shoveled out through the shovel block 604, and the shoveled oil mixture is allowed to enter the collection box 603 through the slot 607 for centralized collection through the inclined block 606 at the bottom of the chamber 605, which can reduce the wear of the pulley 602 and efficiently and thoroughly clean the slide 18, thereby ensuring the normal operation and service life of the equipment and improving the work safety rate. Secondly, when multiple buffering is performed on the swing generated during the movement and transportation of the lifting equipment, the counterweight plate 704 and the slider 708 are connected by sliding in the installation frame 701, and the counterweight plate 704 and the slider 708 are elastically connected by a spring 714. A limiting sleeve 712 is provided at the bottom of the through hole 710 in the slider 708, and the steel cable 16 passes through the through hole 710 and the limiting sleeve 712 in turn to lift the prefabricated block. When the steel cable 16 swings in the limiting sleeve 712, it will first drive the slider 708 to squeeze the spring 714 on the slide bar 713 through the opening 709. Since the two ends of the spring 714 are elastically connected to the counterweight plate 704 and the slider 708 respectively, the slider 708 will slide repeatedly in the installation frame 701 under the traction of the steel cable 16, thereby being buffered multiple times by the spring 714. The swing amplitude of the steel cable 16 is initially limited by the limiting sleeve 712. Since the counterweight plate 704 and the slider 708 are elastically connected by the spring 714, the swing amplitude of the steel cable 16 is avoided. Compared with the fixed connection, the wear of the steel cable 16 can be reduced. The counterweight plate 704 can be installed according to the weight of the prefabricated block to be hoisted, thereby enhancing the anti-swaying effect of the steel cable 16.
