[0030] Embodiment 1

[0031] Please refer to Figures 1 - 5 As shown, in this embodiment, an assembly-type precast component hoisting positioner is provided, including: a bottom plate 2 and two side plates 1. The bottom plate 2 is fixedly connected between the bottoms of the two side plates 1. A plurality of pull plates 5 are slidably fitted on the upper sides of the two side plates 1. A movable seat 6 is rotatably fitted on each of the plurality of pull plates 5. A hoisting steel cable 3 is provided on the upper sides of the plurality of movable seats 6. One end of each of the plurality of hoisting steel cables 3 is provided with a hook 4;

[0032] Positioning components 9 are provided on the opposite sides of the two side plates 1. An extrusion component 10 corresponding to the positioning component 9 is arranged inside the side plate 1. The extrusion component 10 is connected to the plurality of pull plates 5 on the same side of the side plate 1.

[0033] By providing the extrusion component 10, when the traveling crane hoists the plurality of pull plates 5 through the hook 4 and the hoisting steel cable 3, the plurality of pull plates 5 move upward to drive the two positioning components 9 to clamp and position the two sides of the precast component through the extrusion component 10, enabling the positioning component 9 to continuously position the precast component during the hoisting process, reducing the need for additional operations to position the precast component, and thus improving the hoisting efficiency of the precast component.

[0034] As Figures 3 - 5 shown, the positioning component 9 of this embodiment includes a limiting groove 901 opened on one side of the side plate 1, a movable plate 902 slidably fitted in the limiting groove 901, a positioning block 903 arranged on one side of the movable plate 902, and a plurality of elastic members 904 arranged between the positioning block 903 and the limiting groove 901; the elastic members 904 are springs or elastic telescopic rods; a plurality of grooves are opened on the upper side of the side plate 1, the pull plate 5 is slidably fitted in the grooves, and an inner cavity 11 communicating with the plurality of grooves and the limiting groove 901 is arranged inside the side plate 1. The extrusion component 10 is located in the inner cavity 11;

[0035] As Figure 5 shown, the extrusion assembly 10 of this embodiment includes a connecting rod 1001 slidably fitted in the inner cavity 11 and fixedly connected to a plurality of the pulling plates 5, a toothed plate 1002 arranged on the lower side of the connecting rod 1001, a cam 1003 rotatably fitted in the inner cavity 11 and abutted against the movable plate 902, and a plurality of teeth 1004 arranged on half of the circumferential side of the cam 1003 and meshed with the toothed plate 1002.

[0036] When the traveling crane lifts the prefabricated components in the bottom plate 2 and the two side plates 1 through the hook 4, the hoisting steel cable 3 and the movable seat 6, the plurality of movable seats 6 lift the plurality of pulling plates 5. The upward movement of the plurality of pulling plates 5 drives the movement of the connecting rod 1001. The movement of the connecting rod 1001 drives the movement of the toothed plate 1002. The movement of the toothed plate 1002 drives the rotation of the cam 1003 through the engagement with the plurality of teeth 1004. The rotation of the cam 1003 abuts and extrudes the movable plate 902. The extrusion movement of the movable plate 902 drives the movement of the positioning block 903. The positioning blocks 903 on the two side plates 1 clamp and position the two sides of the segmented hull, enabling the positioning assembly 9 to continuously position the prefabricated components during the hoisting process, reducing the need for additional operations to position the prefabricated components, and thus improving the hoisting efficiency of the prefabricated components. In this embodiment, the cam 1003 is a steel member. In other embodiments, the structure of the extrusion assembly 10 can also be replaced with a lead screw and a nut. The lead screw and the nut are both arranged in the inner cavity 11. The upward pulling of the pulling plate 5 drives the rotation of the nut. The rotation of the nut drives the lead screw to move towards the movable plate 902, so that the positioning block 903 clamps the prefabricated component.

[0037] Anti-slip rubber pads are arranged above the bottom plate 2 and on one side of the positioning block 903 in this embodiment. Among them, the anti-slip rubber pads increase the friction between the bottom plate 2 and the positioning block 903 and the prefabricated component, thereby improving the stability of hoisting the prefabricated component.

[0038] The above content is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
