[0002] Lifting equipment, also known as lifting work platform, is a multifunctional lifting mechanical equipment. It can be divided into fixed and mobile, guide rail type, curved arm type, scissors type, chain type, loading and unloading platform, etc. The more common lifting equipment is the scissors type lift, which is often used for rescue and decoration.

[0003] When the platform of the existing lifting equipment is lifted, the bottom of the equipment is in a stationary state, while the platform on the top is constantly rising, and the scissor-type structure in the middle is constantly deforming, which makes it easier for a large gap to appear between the top and bottom of the equipment. When a moving object enters the gap at the bottom of the lifting equipment and gets stuck, it is easy to interfere with the lifting of the platform and even cause damage to the scissor-type structure on the equipment. Therefore, a protective device is needed to protect the lifting equipment. In addition, some existing protective devices are separated from the lifting equipment when in use, and the size and weight of the protective device are comparable to those of the lifting equipment, so the protective device is time-consuming to move and install, which is not conducive to the quick use of the protective device.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4As shown, the high-safety lifting equipment protection device of this embodiment includes a bottom frame 1, and the bottom frame 1 and the rotating plate 8 are enclosed to form a closed "rectangle", and when the rotating plate 8 is rotated along the circular plate 5, an opening appears on one side of the bottom frame 1, thereby realizing the surrounding of the lifting equipment by the protection device, and a top frame 3 is provided on the top of the bottom frame 1, and the top frame 3 and the rotating bar 9 are also enclosed to form a closed "rectangle", so that the telescopic cloth 2 can surround the lifting equipment to form a rectangular cylindrical structure, and enclose and seal the gap generated after the equipment is raised, thereby reducing the moving object from entering the gap at the bottom of the lifting equipment and reducing the probability of the lifting equipment being damaged. Notches 4 are provided on both sides of the bottom of the bottom frame 1, and the width of the notch 4 is compatible with the fork of the forklift, so that the forklift can fork up the entire device for transportation, and a circular plate 5 is provided on one side of the bottom frame 1, and the circular plate 5 can be used as a connecting piece between the bottom frame 1 and the rotating plate 8, so that the rotating plate 8 can rotate along one side of the bottom frame 1, thereby realizing the opening of one side of the bottom frame 1, and the circular plate 5 can be used as a connecting piece between the bottom frame 1 and the rotating plate 8, so that the rotating plate 8 can rotate along one side of the bottom frame 1, thereby realizing the opening of the circular plate 5. The top of the swivel plate 8 is provided with a rotating plate 8, and the rotating plate 8 is provided with a rotating strip 9, which can rotate with the rotation of the swivel plate 8, so that one side of the top frame 3 is also opened. The bottom of the top frame 3 and the rotating strip 9 are provided with a retractable cloth 2. The surface of the retractable cloth 2 is provided with a plurality of folds, which can be folded, so as to realize the stretching and expansion and contraction and retraction of the retractable cloth 2, thereby reducing the interference of the protective device to the lifting equipment after the landing. The bottom ends of the bottom frame 1 and the swivel plate 8 are both equipped with rollers 10. The rollers 10 facilitate pushing the protective device along the ground, thereby facilitating the rapid docking and installation of the protective device with the lifting equipment. One end of the swivel plate 8 is fixedly connected to a first magnet sheet 15, and a second magnet sheet 16 is fixedly connected to an inner wall of one side of the bottom frame 1. The first magnet sheet 15 and the second magnet sheet 16 can be fixed to each other by magnetic attraction, so that the end of the swivel plate 8 can be fixed by the magnetic force of the magnet when it is in contact with the bottom frame 1, thereby facilitating the quick use of the protective device.

[0024] Specifically, the top ends of the two telescopic cloths 2 are fixedly connected to the bottom ends of the top frame 3 and the turning bar 9, respectively, and the bottom ends of the two telescopic cloths 2 are fixedly connected to the top ends of the bottom frame 1 and the turning plate 8, respectively. The gap between the two telescopic cloths 2 does not exist when the turning bar 9 and the top frame 3 are closed, so that the telescopic cloths 2 can form a relatively closed structure at the bottom of the lifting device, thereby reducing the probability of moving objects entering the gap in the lifting device.

[0025] Furthermore, the top frame 3 and the turn bar 9 are movably connected to the bottom frame 1 and the turn plate 8 respectively through the telescopic cloth 2. The top frame 3 and the turn bar 9 are both magnetic, so that the top frame 3 and the turn bar 9 can be fixed to the bottom end of the platform of the lifting equipment by magnetic adsorption, thereby achieving the stretching of the top end of the telescopic cloth 2 by the top frame 3 and the turn bar 9.

[0026] Furthermore, a connecting block 14 is fixedly connected to the bottom end of the circular plate 5, and the connecting block 14 is rotatably connected to the bottom frame 1. The circular plate 5 is rotatably connected to the bottom frame 1 through the connecting block 14, and the rotating plate 8 is movably connected to the bottom frame 1 through the circular plate 5. The bottom end diameter of the connecting block 14 is larger than the top end diameter, so that the circular plate 5 can maintain better stability when rotating along a corner of the bottom frame 1.

[0027] Furthermore, a vertical column 6 is fixedly connected to the top of the circular plate 5, and a slot 13 is provided inside the vertical column 6. The function of the vertical column 6 is to provide a reference object for the telescopic cloth 2 to refer to when it is retracted and gathered, so that the telescopic cloth 2 is not easily distorted and is more conducive to the retraction and gathering of the telescopic cloth 2.

[0028] Furthermore, the slot 13 is internally movably connected to a vertical rod 11, and the vertical rod 11 is externally movably sleeved with a spring 12. The outer diameter of the vertical rod 11 is smaller than the inner diameter of the slot 13, so that the vertical rod 11 can be smoothly inserted into the slot 13, so that the telescopic cloth 2 maintains better stability after returning to its original position.

[0029] Furthermore, the top of the spring 12 is fixedly connected with a card plate 7, the card plate 7 is fixedly connected to the vertical rod 11, and the bottom end of the spring 12 is fixedly connected to the bottom end of the inner side of the card slot 13. The function of the spring 12 is to connect the card plate 7 with the vertical column 6, so that the card plate 7 can be re-attached to the top of the vertical column 6 after the telescopic cloth 2 returns to its position, which is beneficial to the subsequent stretching and expansion of the telescopic cloth 2.

[0030] The method of using this embodiment is as follows: when using the present high-safety lifting equipment protection device, the forks on the forklift can be engaged with the notch 4 on the bottom frame 1, so that the forklift can carry the present protection device to the location of the lifting equipment. After the device is put back on the ground, the rotating plate 8 can be rotated along a corner of the bottom frame 1 through the circular plate 5, so that the roller 10 at the bottom end of the rotating plate 8 rolls along the ground, so that the rotating plate 8 is rotated along the bottom frame 1 with the circular plate 5 as the center, driving the rotating bar 9 and the top frame 3 to separate, so that an opening appears on one side of the bottom frame 1, and then the present device can be pushed to the bottom of the lifting equipment through the roller 10, and then the rotating plate 8 and the bottom frame 1 are closed again. At this time, the first magnet sheet 15 and the second magnet sheet 16 are again adsorbed by magnetic force, so that the bottom frame 1 and the rotating plate 8 as well as the rotating bar 9 and the top frame 3 are connected. The top frame 3 and the rotating bar 9 are re-enclosed into a rectangle, and then the top frame 3 and the rotating bar 9 are lifted to the bottom end of the lifting platform, so that the top frame 3 and the rotating bar 9 are adsorbed and fixed to the bottom end of the lifting equipment platform by magnetic force. When the lifting equipment platform rises, the top frame 3 and the rotating bar 9 linked with the platform will also be lifted, so that the telescopic cloth 2 begins to be stretched and unfolded, and the gap where the running scissors-type structure is located is enclosed, so that objects moving from the outside are not easy to enter the gap where the scissors-type structure is running. At the same time, the card plate 7 and the card rod will be separated from the top and inside of the card slot 13 of the vertical column 6, and the spring 12 will also be stretched. When the platform descends, the telescopic cloth 2 is compressed and retracted under the action of the top frame 3 and the rotating bar 9, and the vertical rod 11 and the spring 12 return to the card slot 13 of the vertical column 6, and the card plate 7 also returns to the top of the vertical column 6.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
