DETAILED DESCRIPTION
[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.
[0020] like Figure 1 As shown, a prefabricated component lifting and positioning device provided in this embodiment includes two relatively arranged guide mechanisms 1, among which one of the guide mechanisms 1 is provided with a horizontally extending positioning rod 2 at the bottom, and the other guide mechanism 1 is provided with a slot 3 at the bottom, and the positioning rod 2 of one guide mechanism 1 is inserted into the slot 3 of the other guide mechanism 1, so that a guide opening 17 with a larger upper part and a smaller lower part and a positioning opening 18 with equal upper and lower parts connected to the lower end of the guide opening 17 are formed between the two guide mechanisms 1.
[0021] In a specific embodiment, Figure 2 , Figure 3 As shown, the guide mechanism 1 includes a surrounding frame 11 , a first crossbar 12 , a first shaft 13 , a second shaft 14 , a first bearing 15 , a second bearing 16 , a guide port 17 , a positioning port 18 , and a base frame 19 .
[0022] The surrounding frame 11 includes a first vertical rod 111 , a second vertical rod 112 , a first diagonal rod 113 , a second diagonal rod 114 , a second cross rod 115 , a bottom beam 116 and a third diagonal rod 117 .
[0023] The second vertical pole 112 is arranged beside the first vertical pole 111, and the first oblique rod 113 is connected to the upper end of the second vertical pole 112 and inclined toward the first vertical pole 111. A bottom beam 116 extending horizontally toward the first vertical pole 111 is provided at the bottom of the second vertical pole 112, and a second oblique rod 114 is connected between the bottom beam 116 and the first vertical pole 111. A plurality of second cross bars 115 are connected between the first oblique rod 113 and the first vertical pole 111. A third oblique rod 117 is connected between the first oblique rod 113 and the bottom beam 116. The enclosure 11 is enclosed by the first vertical pole 111, the second vertical pole 112, the first oblique rod 113, the second oblique rod 114, the second cross bar 115, the bottom beam 116, and the third oblique rod 117 to form a closed and stable frame structure.
[0024] The first vertical rod 111 and the first oblique rod 113 are flush with each other at the top and connected by a small-sized second crossbar 115. The lower end of the second oblique rod 114 is connected to a bottom frame 19. The bottom frame 19 and the second oblique rod 114 form a triangle.
[0025] In two oppositely arranged guide mechanisms 1, the positioning opening 18 is formed between the two second vertical rods 112, and the guiding opening 17 is formed between the two first oblique rods 113. The bottom of the second vertical rod 112 of one guide mechanism 1 is connected to the positioning rod 2, and the bottom of the second vertical rod 112 of the other guide mechanism 1 is provided with the slot 3.
[0026] The guide mechanism 1 has two frames 11 spaced apart, and a plurality of first crossbars 12 and a plurality of first shafts 13 are connected between the two frames 11. The plurality of first shafts 13 are connected to the second vertical rod 112 and the first diagonal rod 113. The first shafts 13 are provided with a plurality of first bearings 15, such as Figure 5 As shown, the outer circumferential surface of the first bearing 15 extends out of the first oblique rod 113 and the second vertical rod 112 to be located in the guide opening 17 and the positioning opening 18, and the extended outer circumferential surface can contact the prefabricated component 5 to play a guiding and positioning role. The rest of the frame 11 is connected through the first crossbar 12.
[0027] A second shaft 14 is connected between the bottom frames 19 at the bottom of the two enclosures 11, and three second bearings 16 are sleeved on the second shaft 14. The lower surface of the second bearing 16 is flush with the lower surface of the bottom beam 116, and both are placed on the ground.
[0028] like Figure 2 As shown, a locking bolt 4 is provided on the bottom beam 116 where the slot 3 is provided. The locking bolt 4 is threadedly connected to the side wall of the bottom beam 116 , and the end of the locking bolt 4 extends into the slot 3 .
[0029] like Figure 4 , Figure 5As shown, when in use, two sets of guide mechanisms 1 are used according to the size of the prefabricated component 5. The guide mechanisms 1 are first docked and placed at the position where the prefabricated component 5 needs to be installed. The docking method is to insert the positioning rod 2 of one guide mechanism 1 into the slot 3 of the other guide mechanism 1, and then tighten the locking bolt 4 so that the locking bolt 4 and the positioning rod 2 are abutted and locked.
[0030] Then hoist the prefabricated component 5. Under the action of the guide opening 17, which is larger at the top and smaller at the bottom, the prefabricated component 5 enters the positioning opening 18, and slides down quickly under the rolling contact of the first bearing 15 provided in the positioning opening 18 until the prefabricated component 5 lands. A 2-cm-high height adjustment platform is provided on the side where the prefabricated component 5 is installed, and the height of the positioning rod 2 is 1 cm. The landing of the prefabricated component 5 means that it is placed on the height adjustment platform. The guide mechanism 1 can accurately hoist the prefabricated component 5 to the required position. Then loosen the locking bolt 4, pull out one or two guide mechanisms 1, and then proceed with the installation of the prefabricated component 5.
[0031] The second bearing 16 on the second shaft 14 on the guide mechanism 1 acts as a wheel, making it easier to drag the guide mechanism 1 to a desired position.
[0032] In the above installation method, it is only necessary to find the position of the guide mechanism 1. After the position of the guide mechanism 1 is determined, the prefabricated component 5 is hoisted in the positioning opening 18 and contacts the first bearing 15 to achieve position limiting, so as to ensure the accurate position of the prefabricated component 5. Therefore, it is no longer necessary to use a pry bar to pry the prefabricated component 5, thereby avoiding damage to the outer surface of the prefabricated component 5 and ensuring the quality of the prefabricated component 5.
[0033] The bottom of the two guide mechanisms 1 is supported on the ground by two base frames 19, two bottom beams 116 and a positioning rod 2, and has high stability. In addition, the second bearing 16 can also be replaced with a wheel with a foot brake to further improve the support stability.
[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
