[0023] The present application will be further described in detail below with reference to the accompanying drawings.
[0024] This application discloses a hoisting device for prefabricated building components.
[0025] Reference Figure 1 , Figure 2 The prefabricated building component hoisting equipment includes two opposing support frames 1, with a horizontally positioned crossbeam 2 mounted on top of each support frame 1. A sliding seat 3 is installed on top of the crossbeam 2, and a motor-driven winch 4 is fixedly mounted on the sliding seat 3. Multiple strands of steel wire rope 40 are wound around the drum of the winch 4. A lifting device 41 for hoisting the building components is installed at the bottom of the lifting rope 40. The lifting device 41 includes two parallel lifting plates 410, with a movable pulley 411 rotatably mounted inside each lifting plate 410. A hook 412 is rotatably mounted at the bottom of each lifting plate 410, with the rotation axis of the hook 412 vertically positioned. The lifting ropes 40 are wound around their respective opposing movable pulleys 411, and then the other end of the lifting rope 40 is stretched upwards and fixed to the sliding seat 3.
[0026] The winch 4 is powered by a motor, which reduces the speed and increases the torque through a reducer, driving the drum to rotate. As the drum rotates, the lifting rope 40 wound around it moves accordingly, thereby lifting or dragging the heavy object.
[0027] like Figure 2 , Figure 3As shown, a horizontally arranged first track 8 is fixedly installed on the crossbeam frame 2. Multiple first pulleys 30 are rotatably mounted on the bottom of the sliding seat 3, each first pulley 30 rolling on its respective opposite first track 8. The sliding seat 3 is rolled on the crossbeam frame 2 along the length of the first track 8 via the first pulleys 30. A first drive source 31 for driving the first pulleys 30 to rotate is also fixedly installed on the sliding seat 3. In this embodiment, the first drive source 31 includes a motor and a reducer. After the speed is reduced by the reducer, the first drive source 31 drives the first pulleys 30 to roll on the first track 8 via the rotating wheel that is in contact with the first pulleys 30. As the first pulleys 30 roll, the sliding seat 3 can slide left and right on the crossbeam frame 2.
[0028] like Figure 2 , Figure 3 As shown, a horizontally arranged second track 9 is fixedly installed on the top of the support frame 1. The length directions of the first track 8 and the second track 9 are perpendicular to each other. A second pulley 20 is rotatably mounted on the crossbeam frame 2, and the second pulley 20 rolls along the length direction of the second track 9 on the support frame 1. A second drive source 21 for driving the second pulley 20 to rotate is fixedly installed on the crossbeam frame 2. The second drive source 21 also includes a motor and a reducer. The driving method of the second drive source 21 is the same as that of the first drive source 31, and will not be described again here. Driven by the second drive source 21, the crossbeam frame 2 slides back and forth along the length direction of the second track 9.
[0029] like Figure 3 , Figure 4 As shown, a horizontally positioned limiting plate 5 is fixedly installed at the bottom of the sliding seat 3 via two connecting rods. A limiting rod 6 is movably threaded through the limiting plate 5 along the lifting direction of the lifting device 41, and the length of the limiting rod 6 is set along the lifting direction of the lifting rope 40. Multiple mounting plates 42 are fixedly installed on the outer wall of the lifting platform 410, and the bottom of the limiting rod 6 is threadedly connected to its respective mounting plate 42. The top of the limiting rod 6 protrudes from the upper surface of the limiting plate 5, and the limiting rod 6 rises and falls synchronously with the lifting device 41. An anti-detachment component 60 is threadedly connected to the top of the limiting rod 6. The maximum outer diameter of the anti-detachment component 60 is larger than the outer diameter of the limiting rod 6, and the anti-detachment component 60 is used to prevent the limiting rod 6 from detaching from the limiting plate 5.
[0030] When hoisting building components, the lifting device 41, under the constraint of the limiting rod 6, ensures that it moves up and down along the length of the limiting rod 6, greatly reducing the probability of the building components swaying due to external forces during hoisting. This further improves the stability of the lifting device 41, effectively reduces the risk of building components falling, and increases the safety factor.
[0031] like Figure 3 , Figure 4As shown, a spacer plate 7 is provided on the outside of the limiting rod 6, located above the lifting device 41. Multiple through holes 70 are provided on the spacer plate 7 for the lifting ropes 40 to pass through, with each strand of the lifting rope 40 passing through its respective corresponding through hole 70. A mounting base 71 is fixedly provided on the spacer plate 7, opposite to the limiting rod 6, and the limiting rod 6 is movably inserted into the mounting base 71. Fasteners 72 are threaded onto the mounting base 71; in this embodiment, the fasteners 72 are bolts. The fasteners 72 are used to tighten and fix the spacer plate 7 onto the limiting rod 6. When the fasteners 72 are released from locking the spacer plate 7, the spacer plate 7 can be raised and lowered along the length of the limiting rod 6. By adjusting the height of the spacer plate 7 to an appropriate position, the spacer plate 7 ensures that each strand of the lifting rope 40 maintains a specified spacing, effectively preventing the strands of the lifting rope 40 from whipping against each other, suppressing the vibration of the lifting rope 40, and further improving the stability of the lifting device 41.
[0032] like Figure 3 , Figure 4 As shown, two spacer plates 50 are fixedly installed on the limiting plate 5. Multiple through holes 51 are passed through the spacer plates 50. The suspension ropes 40 are respectively passed through their respective through holes 51. The through holes 51 can also limit the suspension ropes 40, thereby further suppressing the swing amplitude of the suspension ropes 40 and improving the stability of the suspension ropes 40.
[0033] The implementation principle is as follows: When the lifting device 41 is hoisting the building component, the limiting rod 6 ensures that the lifting device 41 moves up and down along the length of the limiting rod 6, greatly reducing the probability of the building component swaying due to external forces during hoisting. This further improves the stability of the lifting device 41, effectively reduces the risk of building components falling, and increases the safety factor.
[0034] The spacer plate 7 ensures that each strand of the lifting rope 40 is kept at a specified interval, thereby effectively preventing the strands of the lifting rope 40 from whipping each other, suppressing the vibration of the lifting rope 40, and further improving the stability of the lifting device 41. The through hole 51 can also limit the lifting rope 40, thereby further suppressing the swing amplitude of the lifting rope 40 and improving the stability of the lifting rope 40.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
