Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated component hoisting equipment, and in particular to a threaded locking cylindrical hoisting device for hoisting prefabricated components. Background Technology

[0002] In existing technologies, round steel hooks are commonly used as lifting devices for precast components. The lifting load of precast components is mainly carried by the tensile bearing capacity of the round steel hooks. When calculating their bearing capacity, for safety reasons, one hook is usually reserved as a reserve. Therefore, it is only suitable for lifting components with uniform stress and clear mechanical transmission paths. However, for components with asymmetrical center of gravity distribution (such as curved components), the stress distribution of multiple lifting points is uneven. It is necessary to increase the safety reserve of each lifting point according to the component being lifted, which makes the lifting device less applicable to components with asymmetrical center of gravity distribution.

[0003] Therefore, how to improve the structure of the hoisting device to make it more widely applicable to hoisting components with asymmetrical centers of gravity has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The hoisting connector includes a connecting bolt cylinder, and one end of the connecting bolt cylinder is fixedly connected to a connecting end plate.

[0007] The outer side of the hoisting support is fixedly connected to a lifting hook. The hoisting support includes a support bolt cylinder. One end of the support bolt cylinder is fixedly connected to a support end plate. The support end plate has bolt holes.

[0008] The locking component includes a locking bolt and a threaded cylinder, the threaded cylinder being fixedly connected to the connecting bolt cylinder, and a locking end plate being fixedly connected to one end of the threaded cylinder;

[0009] When the bearing bolt cylinder is inserted into the connecting bolt cylinder to connect the lifting connector and the lifting bearing, the locking bolt can be screwed into the bolt hole and the threaded cylinder in sequence and locked.

[0010] Preferably, the connecting end plate has an opening that communicates with the grouting hole of the precast component.

[0011] Preferably, several of the connecting ribs are arranged on the outside of the connecting bolt cylinder.

Detailed Implementation

[0024] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0025] Example:

[0026] like Figures 1-6 As shown, the threaded locking cylindrical hoisting device for hoisting precast components includes a hoisting connector 1, a hoisting bearing 2, and a locking component 3. The hoisting connector 1 is fixed in the hoisting bolt hole opened on the precast component 4.

[0027] The outer side of the hoisting connector 1 is fixedly connected with several connecting ribs 13. The connecting ribs 13 are welded and fixed to the stress ribs in the precast component 4. The hoisting connector 1 includes a connecting bolt cylinder 11. One end of the connecting bolt cylinder 11 is welded and fixed with a connecting end plate 12.

[0028] The hoisting support component 2 includes a support bolt cylinder 21, one end of which is welded and fixed with a support end plate 22. The support end plate 22 has bolt holes 24. The hoisting hook 23 is fixedly connected to the outside of the support bolt cylinder 21.

[0029] Locking component 3 includes locking bolt 31 and threaded cylinder 32. The threaded cylinder 32 is fixedly connected to the connecting bolt cylinder 11, and a locking end plate 33 is fixedly connected to one end of the threaded cylinder 32.

[0030] When the load-bearing bolt cylinder 21 is inserted into the connecting bolt cylinder 11 to connect the lifting connector 1 and the lifting load-bearing component 2, the locking bolt 31 can be screwed into the bolt hole 24 and the threaded cylinder 32 in sequence and locked.

[0031] The main innovation of this utility model is that the cylindrical structure of the hoisting connector 1 and the hoisting bearing 2 has high strength and high stability, and with the locking part 3 to prevent falling off, it can stably hoist the prefabricated component 1 with an asymmetrical center of gravity.

[0032] In this embodiment, the connecting end plate 12 and the locking end plate 33 can prevent concrete from clogging the pipe hole during the fabrication of the precast component 1.

[0033] A hole is made at the center of the connecting end plate 12, which is connected to the grouting hole 5 of the precast component 4. The connecting bolt cylinder 11 is used as a grouting hole in conjunction with the hole.

[0034] Several connecting ribs 13 are arranged on the outside of the connecting bolt cylinder 11.

[0035] like Figure 7 and Figure 8 As shown, in some embodiments, a plurality of connecting ribs 13 are arranged on one side of the connecting end plate 12.

[0036] The working principle and usage process of this utility model are as follows: Before hoisting the precast component 1, the bearing bolt cylinder 21 of the hoisting bearing component 2 is inserted into the connecting bolt cylinder 11 of the hoisting connector 1. Then, the locking bolt 31 of the locking component 3 is tightened in the threaded cylinder 32 through the bolt through hole 24 to prevent the hoisting bearing component 2 from slipping and falling off when the hoisting cable 23 is hoisted on the bearing bolt cylinder 21.
