Description

Technical Field

[0001] This application relates to the field of lifting protection equipment technology, and in particular to a protective enclosure for a building lifting frame. Background Technology

[0002] A construction lifting frame is a device used in construction to lift building materials, components, or equipment. It is typically made of welded or assembled metal materials such as steel, possessing sufficient strength and rigidity to withstand the weight and external forces during lifting. To ensure safety during lifting and prevent items from falling or personnel from being injured, construction lifting frames are usually equipped with protective barriers to prevent items or personnel from slipping off the sides.

[0003] In related technologies, the height of the protective barriers installed on the lifting frame is usually fixed during use. That is, the protective height cannot be changed or adjusted according to the height of the object to be lifted. When the height of the object to be lifted is relatively high and exceeds the safe protection height of the protective barrier, the protective performance of the barrier for tall objects will be reduced, which will pose certain safety hazards. Consequently, it cannot meet the safety protection requirements for lifting operations of objects of different heights, and its scope of application is limited.

[0004] Therefore, we propose a protective enclosure for building lifting frames to solve the above problems. Utility Model Content

[0023] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a protective enclosure for a building lifting frame, including a lifting frame bearing base plate 1 and an enclosure mechanism disposed on the lifting frame bearing base plate 1, wherein:

[0025] The fencing mechanism includes a U-shaped base frame 2, retractable retaining posts 3, a U-shaped top frame 4, and an adjustment and positioning assembly 5. The U-shaped base frame 2 is fixedly installed on the top of the lifting frame bearing base plate 1. Multiple retractable retaining posts 3 are provided, all evenly distributed on the U-shaped base frame 2. A reinforcing beam 6 is fixedly connected between adjacent retractable retaining posts 3. The multiple retractable retaining posts 3 evenly distributed on the U-shaped base frame 2 and connected by the reinforcing beam 6 form a stable frame structure, enhancing the overall deformation resistance of the fencing mechanism. Even when subjected to certain external impacts, it can withstand [the force of the impact]. To maintain structural integrity and effectively protect the lifting area, the retractable stop column 3 includes a hollow column 31 and a telescopic vertical rod 32. The bottom end of the hollow column 31 is fixedly connected to the top of the U-shaped bottom frame 2. The bottom end of the telescopic vertical rod 32 is slidably installed inside the hollow column 31. The top end of the telescopic vertical rod 32 is fixedly connected to the bottom of the U-shaped top frame 4. The U-shaped top frame 4 is fixedly installed on the top of multiple retractable stop columns 3. The number of adjusting positioning components 5 is set to four. The four adjusting positioning components 5 are respectively set on the left and right sides of the lifting frame bearing base plate 1 and arranged symmetrically in pairs. The four adjusting positioning components 5 are used to lock the height position of the U-shaped top frame 4.

[0026] In this embodiment, the aforementioned adjustment and positioning assembly 5 includes a fixed column 51, a vertical shaft 53, a connecting plate 54, and a locking bolt 55. The fixed column 51 is fixedly installed on one side wall of the lifting frame bearing base plate 1. A vertical groove 52 is provided at the top of the fixed column 51, and the bottom end of the vertical shaft 53 extends into the vertical groove 52. The connecting plate 54 is fixedly installed at the top of the vertical shaft 53, and one side of the connecting plate 54 is fixedly connected to one side outer wall of the U-shaped top frame 4. The locking bolt 55 is threadedly installed on the side of the fixed column 51 away from the lifting frame bearing base plate 1, and a threaded groove 55 is provided on one side of the vertical shaft 53. 6. One end of the locking bolt 55 is threaded into the threaded groove 56. The number of threaded grooves 56 is set to multiple, and the multiple threaded grooves 56 are evenly distributed. Through the joint action of the four adjusting positioning components 5, the height position of the U-shaped top frame 4 is reliably locked. In addition, multiple equally distributed threaded grooves 56 are set on the vertical shaft 53 of the adjusting positioning component 5. With the locking bolt 55, the protective height of the enclosure mechanism can be flexibly adjusted to adapt to the protection requirements of lifting operations of objects of different heights, and ensure that effective protection can be provided for lifting operations under various working conditions.

[0027] In this embodiment, a rubber damping block 57 is fixedly installed at the bottom end of the vertical shaft 53. The rubber damping block 57 slides in contact with the inner wall of the vertical groove 52. By setting the damping friction generated by the sliding contact between the rubber damping block 57 and the inner wall of the vertical groove 52, the stability of the vertical shaft 53 in the vertical groove 52 can be increased to a certain extent, and the overall stability of the enclosure mechanism can be further improved.

[0028] In this embodiment, a lifting lug 7 is fixedly installed on the side of the fixed column 51 away from the lifting frame bearing base plate 1. The lifting lug 7 is provided with a lifting hole to facilitate the binding of the lifting rope on the lifting equipment, so as to facilitate the safe lifting and transfer of the object placed on the lifting frame bearing base plate 1.

[0029] In this embodiment, an anti-slip pad 8 is fixedly installed on the top of the lifting frame support base plate 1. The anti-slip pad 8 is located inside the U-shaped base frame 2. The anti-slip pad 8 can effectively prevent the object being lifted from sliding on the lifting frame support base plate 1, ensuring the stability and safety of the lifting process and avoiding collisions and damage caused by the object sliding.

[0030] In this embodiment, a buffer pad 9 is fixedly installed at the bottom of the lifting frame support base plate 1. The cross-sectional dimensions of the buffer pad 9 are the same as those of the lifting frame support base plate 1. The buffer pad 9 can effectively buffer and unload the impact force on the lifting frame support base plate 1 when it descends and contacts the ground, thereby reducing the impact of vibration on the structure of the enclosure mechanism and the lifting operation.

[0031] With the above structure, the working principle of the building lifting frame protective enclosure provided in this application is as follows:

[0032] The object is placed on the anti-slip mat 8 on the lifting frame support base plate 1. During the lifting operation, the object is surrounded by the U-shaped bottom frame 2, multiple retractable baffles 3 and U-shaped top frame 4, which can prevent the object from falling from a height due to shaking or collision during the lifting process, thus playing an effective protective role, ensuring the safe operation of the object lifting operation, and protecting the safety of personnel and equipment below and around the object lifting operation area.

[0033] When adjusting the height of the enclosure mechanism, firstly, unscrew one end of each of the four locking bolts 55 out of the corresponding threaded groove 56 to release the locking of the vertical shaft 53, allowing it to slide freely within the vertical groove 52. Since the connecting plate 54 at the top of the vertical shaft 53 is fixedly connected to one side of the outer wall of the U-shaped top frame 4, the U-shaped top frame 4 can be adjusted by moving it up or down. During this upward or downward movement, the telescopic vertical rod 32 will slide within the hollow column 31, allowing the U-shaped top frame 4 to be adjusted to the appropriate height. After adjusting the height, screw one end of each of the four locking bolts 55 into the corresponding threaded grooves 56. Due to the self-locking effect of the threads, the four vertical shafts 53 can be locked and fixed in the corresponding vertical grooves 52, thus reliably locking the height position of the U-shaped top frame 4, completing the height adjustment process. This allows for convenient and flexible adjustment of the protective height of the enclosure mechanism to meet the safety protection needs of lifting objects of different heights, ensuring effective enclosure protection for lifting operations under various working conditions, and greatly expanding the scope of application.
