It is the process of building various types of structures, transforming the lines on design drawings into physical objects at designated locations. Construction includes foundation construction, main structure construction, roofing construction, and decoration construction. During construction, to facilitate work at heights, lifting platforms are used to transfer workers and materials to higher locations. In existing technology, construction lifting platforms consist of a cage, guide rail sections, wall-mounted frames, a transmission mechanism, and an electrical mechanism. An electric motor drives the transmission mechanism, causing the cage to move up and down along the guide rail. The gears in the transmission mechanism mesh with the racks on the guide rail to raise and lower the cage. Although some lifting platforms have protective railings to prevent goods and personnel from falling off, smaller items can easily fall through the gap between the railing and the lifting platform, potentially injuring people below and compromising the safety of the construction lifting platform. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a high-safety construction lifting platform, including a guide rail frame 1, with rack plates at both ends of the guide rail frame 1, and a lifting platform 2 vertically slidably connected inside the guide rail frame 1. Gears with drive motors are provided at both ends of the lifting platform 2. The relative rotation of the gears and rack plates drives the lifting platform 2 to move up and down. A fence 3 is provided along the outer edge of the upper surface of the lifting platform 2 to protect the outer edge of the lifting platform 2. A PLC controller 6 is provided at the upper end of the fence 3. The input terminal of the PLC controller 6 is electrically connected to an external power source to control the start and stop of the entire device. Rollers 7 are provided at both ends of the lifting platform 2. The rollers 7 contact the guide rail frame 1. The relative rotation of the rollers 7 and the guide rail frame 1 reduces the friction force experienced by the lifting platform 2 during movement. A protective mechanism 4 is also included.

[0021] Protective mechanism 4 includes a lifting baffle 41 and a guide slide plate 42. The lifting baffle 41 is movably fitted onto the outer side of the fence 3, and the inner side of the lifting baffle 41 is provided with guide slide plates 42. The guide slide plates 42 are vertically slidably connected to the adjacent vertical posts of the fence 3. The protective mechanism 4 also includes adjusting slip rings 44 and springs 45. The adjusting slip rings 44 are vertically slidably connected to the outer arc surface of the vertical posts of the fence 3, and springs 45 are provided between the adjusting slip rings 44 and the guide slide plates 42 corresponding to the vertical positions. The springs 45 are movably fitted onto the fence 3. When the adjusting slip ring 44 moves downward, the outer arc surface of column 3, through the elastic connection of spring 45, drives the guide slide plate 42 and the lifting baffle 41 to move downward until the lifting baffle 41 contacts the upper surface of the lifting platform 2. The lifting baffle 41 prevents small-volume goods from falling from the edge of the lifting platform 2, improving the safety of the lifting platform. After the lifting baffle 41 contacts the lifting platform 2, as the adjusting slip ring 44 continues to move downward, the spring 45 contracts. Under the elastic force of the spring 45, the position of the lifting baffle 41 is adjusted. For added stability, the protective mechanism 4 also includes a slide 43, an electric push rod 46, and a connecting plate 48. The slide 43 is respectively set on the outer arc surface of the vertical column of the fence 3. The connecting plate 48 is respectively set in the middle of the guide slide plate 42 and the adjusting slip ring 44. The connecting plate 48 is vertically slidably connected to the adjacent slide 43. The electric push rod 46 is respectively set in the upper inner part of the vertical column of the fence 3. The connecting plate 48 in the middle of the adjusting slip ring 44 is fixedly connected to the lower end of the telescopic end of the adjacent electric push rod 46. The input end of the electric push rod 46 is electrically connected to P. The output of the LC controller 6 provides power for the downward movement of the adjusting slip ring 44. The protective mechanism 4 also includes a distance sensor 47, which is respectively set on the surface of the connecting plate 48 in the middle of the guide slide plate 42. The output of the distance sensor 47 is electrically connected to the input of the PLC controller 6 to detect the distance between the guide slide plate 42 and the adjusting slip ring 44 and determine the extension and contraction of the spring 45. The lower surface of the lifting baffle 41 is provided with a rubber pad 5 to make the contact between the lifting baffle 41 and the surface of the lifting platform 2 more compact.

[0022] The working principle of the high-safety construction lifting platform provided by this utility model is as follows: During the construction process, the gear at the lower end of the lifting platform 2 rotates relative to the rack plate on the surface of the guide rail frame 1, driving the lifting platform 2 to move up and down. According to the type of goods placed on the surface of the lifting platform 2, the electric push rod 46 is activated by the PLC controller 6. The telescopic end of the electric push rod 46 drives the adjusting slip ring 44 to move downward. Through the elastic connection of the spring 45, the guide slide plate 42 and the lifting baffle 41 move downward until the rubber pad 5 contacts the upper surface of the lifting platform 2. The lifting baffle 41 prevents small-volume goods from falling from the edge of the lifting platform 2, improving the safety of the lifting platform. When the lifting platform is not in use, the electric push rod 46 can be activated to drive the lifting baffle 41 to reset, so that there is a gap between the lifting baffle 41 and the upper surface of the lifting platform 2, which facilitates the sweeping of dust from the outer edge of the lifting platform 2, making it convenient to clean the surface of the lifting platform 2.

[0023] It is worth noting that the PLC controller 6 disclosed in the above embodiments can be an NX7 model PLC controller, and the electric actuator 46 and the ranging sensor 47 can be freely configured according to the actual application scenario. The electric actuator 46 can be an ANT-52 model electric actuator, and the ranging sensor 47 can be a T150HJG-CGQ model reflective laser ranging sensor. The PLC controller 6 controls the operation of the electric actuator 46 and the ranging sensor 47 using methods commonly used in the prior art.

[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
