Technical Field

[0002] A lifting platform is a kind of lifting machinery that transports people or objects vertically. It also refers to equipment for vertical transportation in logistics systems such as factories and automatic warehouses. Lifting platforms are often equipped with various flat conveying equipment as connecting devices for conveyor lines at different heights. It is generally driven by hydraulics, so it is called a hydraulic lifting platform. In addition to being used for transporting goods at different heights, it is widely used in high-altitude installation, maintenance and other operations. In the construction industry, lifting platforms are usually used instead of manual transportation of various materials.

The protective door is pulled to the side close to the baffle, and the protective door squeezes the lock tongue while rotating, thereby causing the first spring to contract. When the protective door moves to one side of the lock tongue, the first spring drives the lock tongue to reset, thereby realizing the limiting position of the protective door, preventing the protective door from rotating, thereby realizing the protection of materials and ensuring the safety of people.

[0015] (2) The construction engineering lifting platform described in the present invention is convenient for transporting various types of materials. A lifting mechanism for transporting materials is installed on the top of the main body, which is convenient for lifting and lowering materials. It does not require manual handling, saves time and effort, and is simple to operate. That is, two motors are electrically controlled to work at the same time. The motor drives the power pulley to rotate, and the power pulley drives the driven pulley to rotate through the belt, thereby realizing the rotation of the screw. The synchronous rotation of the two screws can realize the lifting and lowering of the mounting plate, thereby enabling the lifting and lowering of the support seat, thereby realizing the transportation of materials. When transporting materials, the lifting and lowering is smooth, avoiding shaking of the lifting platform, and is easy to use. It does not require manual handling, is simple to operate, and saves time and effort.

[0016] (3) The construction engineering lifting platform described in the present invention is convenient for transporting various types of materials. The main body mechanism is provided with a sliding mechanism for driving the movement of materials, thereby facilitating the loading and unloading of materials. A locking mechanism is provided between the main body mechanism and the sliding mechanism, which can limit the sliding mechanism to prevent the sliding mechanism from driving the materials to slide randomly during lifting and lowering, thereby preventing the materials from falling. That is, after the materials are stacked on the slide plate, the lifting mechanism drives the transportation of the materials. When the materials are transported to the target height, when the locking mechanism limits the position of the slide block, the third spring is in a contracted state. When it is necessary to pull the slide plate for unloading, the second pull plate is pulled to the side away from the slide block. The second pull plate drives the first stop block to move while causing the second spring to contract. When the first stop block moves to the top of the second stop block, the third spring is pulled by the first pull plate. When the second stop is contracted inside the support seat, the second spring drives the first stop to reset, thereby realizing the limitation of the slider, preventing the slider from sliding out of the inside of the slider and thus preventing the slider from slipping off. Then the materials on the slider are unloaded, and the operation space is large, which is convenient for unloading. After the unloading is completed, the slider is pushed toward the side close to the baffle plate, and the slider drives the slider to reset, thereby realizing the reset of the limit block, and then the first pull plate is pulled toward the side away from the slider, and the first pull plate drives the second stop to move and causes the third spring to contract. When the second stop is contracted inside the support seat, the second spring drives the first stop to reset, thereby realizing the limitation of the slider, preventing the slider from driving the slider to slide during the lifting process, causing the materials to slip off.

[0017] (4) The construction engineering lifting platform described in the present invention is convenient for transporting various types of materials. A moving mechanism for realizing the movement of the lifting platform is installed at the bottom of the main body mechanism, which can facilitate the movement of the lifting platform without manual handling and is easy to use. A fixing mechanism for limiting the moving mechanism is installed inside the moving mechanism to prevent the lifting platform from sliding randomly; that is: when it is necessary to move the lifting platform, pull the second pull buckle to the side away from the base, the second pull buckle drives the rack to move through the sliding rod, and causes the fourth spring to contract, so that the rack falls off the limit of the gear, and then the limit plate is rotated. The limit plate is rotated inside the base through the rotating rod. When the limit plate is rotated to the second pull buckle The bottom of the base can be reached by releasing the second buckle, and the limiting plate can limit the second buckle, pushing the base. Under the action of the friction force of the ground, the roller rotates inside the base through the rotating shaft, thereby facilitating the movement of the lifting platform. The operation is simple, time-saving and labor-saving. The rotating shaft with an I-shaped cross-section can avoid slipping or deflecting from the inside of the base during rotation. The second buckle is pulled to the side away from the base, and then the limiting plate is rotated so that the limiting plate is located on one side of the second buckle. The second buckle is released, and the fourth spring drives the rack to reset, and the rack meshes with the gear, thereby limiting the rotating shaft and preventing the rotating shaft from rotating, thereby fixing the lifting platform. The operation is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

When it is necessary to unload and pull the slide plate 21, the second pull plate 54 is pulled to the side away from the slider 24. The second pull plate 54 drives the first stop block 53 to move and causes the second spring 51 to contract. When the first stop block 53 moves to the top of the second stop block 55, the third spring 56 drives the second stop block 55 to reset through the first pull plate 52, thereby limiting the first stop block 53. The operator drives the slide plate 21 to move through the pull groove 22, and the slide plate 21 drives the slide block 24 to move inside the slide groove 23. The slide block 24 drives the limiting block 26 to slide inside the limiting groove 25, thereby preventing the slide block 24 from detaching from the inside of the slide groove 23, thereby preventing the slide plate 21 from sliding off, and then unloading the materials on the slide plate 21. The operation space is large, which is convenient for unloading. After unloading is completed, the slide plate 21 is pushed toward the side close to the baffle plate 12, and the slide plate 21 drives the slider 24 to reset, thereby realizing the reset of the limit block 26, and then the first pull plate 52 is pulled toward the side away from the slide plate 21, and the first pull plate 52 drives the second stop block 55 to move and causes the third spring 56 to contract. When the second stop block 55 is contracted inside the support seat 11, the second spring 51 drives the first stop block 53 to reset, thereby realizing the limitation of the slider 24, and preventing the slider 24 from driving the slide plate 21 to slide during the lifting process, causing the materials to slip. When it is necessary to move the lifting platform, the second pull buckle 74 is pulled toward the side away from the base 61, and the second pull buckle 74 drives the rack 72 to move through the slide rod 75, and causes the fourth spring 76 to contract.The rack 72 is then disengaged from the position limiting function on the gear 71, and then the limiting plate 77 is rotated. The limiting plate 77 is rotated inside the base 61 through the rotating rod 73. When the limiting plate 77 is rotated to the bottom of the second buckle 74, the second buckle 74 can be released. The limiting plate 77 can limit the second buckle 74 and push the base 61. Under the action of the friction force of the ground, the roller 64 is rotated inside the base 61 through the rotating shaft 62, thereby facilitating the movement of the lifting platform, which is simple to operate and saves time and effort. The rotating shaft 62 with an I-shaped cross section can avoid sliding or deflecting from the inside of the base 61 when rotating. Pull the second buckle 74 to the side away from the base 61, and then rotate the limit plate 77 so that the limit plate 77 is located on one side of the second buckle 74. After that, release the second buckle 74, and the fourth spring 76 drives the rack 72 to reset. The rack 72 meshes with the gear 71, thereby limiting the rotating shaft 62 and preventing the rotating shaft 62 from rotating, thereby fixing the lifting platform.
