Description

Technical Field

[0001] The utility model relates to the technical field of construction hoisting, in particular to a safe object hoisting device for parking lot construction. Background Art

[0002] Construction lifting usually refers to the use of lifting equipment or cranes and other tools to lift and move objects at construction sites or other engineering sites. This operation usually needs to follow strict safety standards and procedures to ensure safety and efficiency during the construction process. The equipment used in construction lifting can quickly move goods to a higher operating height and easily unload construction steel, saving time and effort in construction.

[0003] In this regard, Chinese patent publication number CN206395711U2 discloses a safe object lifting device for subway construction. In the above scheme, it can be seen that when small materials need to be lifted, they can be directly placed in the hanging basket for lifting, and very fine materials can be bagged and hung on the hook. When the lifted material is slightly larger, one end of the material can be placed in the hanging basket and then locked with a chain to ensure the safety of lifting. However, there are still some problems in the specific use of the existing parking lot construction safety lifting device: manually locking the lifting hanger with a chain will increase the fixing time of the steel and reduce work efficiency. In addition, when the goods are suspended and in mid-air, there is still a possibility that the steel will loosen while being placed on the lifting hanger. It is also difficult for the staff below to make real-time limit adjustments to the goods, which may cause steel to fall and injure people during subsequent operations. Utility Model Content

The lower end of the electric push rod 104 is fixedly connected to a retractable support plate 105. The middle part of one side of the slidable adjustment plate 103 is rotatably connected to a threaded rod 106 through a bearing. The top of the front of the main connecting plate 101 is fixedly connected to an adjustment slide plate 107. The inner wall of the adjustment slide plate 107 is slidably connected to the sliding support plate 1 08. A stepper motor 109 is fixedly connected to one side of the back of the sliding support plate 108, and the middle and bottom of the back of the slidable adjustment plate 103 are fixedly connected with rubber protrusions 110. Through the steel limiting reinforcement structure 1 and the bottom support top frame 3, the steel can be quickly limited and fixed according to the amount of steel placed, and when the steel and the lifting hanger rise to mid-air, the stacked steel can still be adjusted in real time to continue to tighten the limit in the case of looseness, thereby avoiding casualties caused by falling steel during subsequent lifting operations. After the slidable adjustment plate 103 contacts the steel, the rubber protrusion 110 increases the contact friction with the steel, making the steel more stable when being lifted.

[0026] See also Figure 4 The output end of the stepper motor 109 is fixedly connected to one end of the threaded rod 106, and the surface of the threaded rod 106 is threadedly connected to the middle part of the front of the main connecting plate 101 through a through hole.
