[0001] This utility model relates to the field of lifting device technology, and in particular to a multi-functional construction lifting device for building engineering. The multi-functional construction lifting device for building engineering is a special lifting equipment adapted to building construction scenarios and based on a stable mechanical structure. Through the combination of functional structures such as guide rails and supports, it can realize the vertical or inclined lifting and precise positioning of personnel, building materials and working platforms at different construction heights. Background Technology

[0002] A lifting device is a type of equipment that uses a mechanical structure to lift and position a load vertically or at an angle. It is widely used in construction, industrial production, logistics and transportation and other scenarios.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing multi-functional construction lifting devices used in construction projects have a fixed load-bearing bracket length, which easily leads to insufficient space when facing a large number of scattered materials, requiring them to be transported in batches or piled up at the edge of the platform, which not only affects work efficiency but also poses a risk of falling; the fixed area is difficult to meet the needs of temporary expansion of operating space, and personnel are easily obstructed by materials when working in narrow areas, increasing the safety hazards of collisions or imbalance. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the length of the load-bearing bracket of the multi-functional construction lifting device used in building engineering is fixed. Therefore, we propose a multi-functional construction lifting device for building engineering.

[0005] To achieve the above objectives, this application adopts the following technical solution: A multifunctional construction lifting device for building engineering, comprising a lifting frame: a lead screw is rotatably connected inside the lifting frame, a sliding nut is slidably connected to the surface of the lead screw, a material rack is fixedly connected to one end of the sliding nut, a motor is fixedly connected to one end of the lifting frame, a telescopic groove is provided inside the material rack, a telescopic frame is slidably connected to both sides of the telescopic groove, two fixing blocks are fixedly connected to both ends of the material rack, a plurality of limiting grooves are provided at both ends of the telescopic frame, a circular groove is provided at one end of the fixing block, a pull rod is slidably connected inside the circular groove, an L-shaped limiting block is fixedly connected to the end of the pull rod away from the telescopic frame, and one end of the L-shaped limiting block is slidably connected to the inside of the limiting groove.

[0006] Preferably, the bottom of the telescopic frame has two T-shaped grooves, and two T-shaped blocks are fixedly connected to both sides of the telescopic grooves. The surface of the T-shaped blocks is slidably connected to the inside of the T-shaped grooves.

[0007] Preferably, the bottom of the telescopic frame is equipped with a plurality of rollers, and the surface of the rollers is rotatably connected to the bottom of the telescopic groove.

[0008] Preferably, a reinforcing frame is fixedly connected to the bottom of the material rack, and the top of the reinforcing frame is slidably connected to the bottom of the telescopic frame.

[0009] Preferably, a spring is slidably connected to the surface of the pull rod, one end of the spring is fixedly connected to the pull rod, and the other end of the spring is fixedly connected to the end of the circular groove away from the telescopic frame.

[0010] Preferably, the top and bottom of the pull rod are provided with sliding grooves, and the top and bottom of the circular groove away from the telescopic frame are fixedly connected with sliding blocks, and the surface of the sliding blocks is slidably connected to the inside of the sliding groove.

[0011] Preferably, scales are provided at both ends of the telescopic frame.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by starting the motor, which is connected to the lead screw via a belt and gears, the motor drives the lead screw to rotate forward or backward. The rotation of the lead screw causes the sliding nut to slide up and down on its surface. The movement of the sliding nut causes the material rack fixedly connected to it to move. By pulling the L-shaped limiting blocks at both ends of the material rack, one end of the L-shaped limiting block moves out of the limiting groove. At this time, the limiting of the telescopic frame inside the telescopic groove is released, and the telescopic frame can be moved as needed to supplement the length of the material rack and increase its bearing area. After adjustment, one end of the L-shaped limiting block is aligned with the limiting groove. Then, the pulling of the L-shaped limiting block is released, and the elasticity of the spring causes the L-shaped limiting block to reset, so that one end of the L-shaped limiting block enters the limiting groove, thereby limiting the telescopic frame. The reinforcing frame is slidably connected to the bottom of the telescopic frame, and at the same time, it supports the bottom of the telescopic frame, increases the load-bearing capacity of the telescopic frame, and prevents the telescopic frame from warping due to heavy objects.

Detailed Implementation

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a multi-functional construction lifting device for building engineering, including a lifting frame 1; a lead screw 2 is rotatably connected inside the lifting frame 1, a sliding nut 3 is slidably connected to the surface of the lead screw 2, a material rack 4 is fixedly connected to one end of the sliding nut 3, a motor 5 is fixedly connected to one end of the lifting frame 1, a telescopic groove 6 is opened inside the material rack 4, telescopic frames 7 are slidably connected to both sides of the telescopic groove 6, two fixing blocks 8 are fixedly connected to both ends of the material rack 4, and several limiting grooves 9 are opened at both ends of the telescopic frames 7. A circular groove 10 is provided at one end of the block 8. A pull rod 11 is slidably connected inside the circular groove 10. An L-shaped limiting block 12 is fixedly connected to the end of the pull rod 11 away from the telescopic frame 7. One end of the L-shaped limiting block 12 is slidably connected to the inside of the limiting groove 9. A spring 17 is slidably connected to the surface of the pull rod 11. One end of the spring 17 is fixedly connected to the pull rod 11. The other end of the spring 17 is fixedly connected to the end of the circular groove 10 away from the telescopic frame 7. A reinforcing frame 16 is fixedly connected to the bottom of the material rack 4. The top of the reinforcing frame 16 is slidably connected to the bottom of the telescopic frame 7.

[0022] Specifically: By starting motor 5, which is connected to lead screw 2 via belt and gears, motor 5 drives lead screw 2 to rotate forward or backward. The rotation of lead screw 2 causes sliding nut 3 to slide up and down on its surface. The movement of sliding nut 3 causes material rack 4, which is fixedly connected to it, to move. By pulling the L-shaped limiting blocks 12 at both ends of material rack 4, one end of the L-shaped limiting block 12 moves out of the limiting groove 9. At this time, the limiting of telescopic frame 7 inside telescopic groove 6 is released, and telescopic frame 7 can be moved as needed to supplement the length of material rack 4 and increase the bearing area of ​​material rack 4. After adjustment, one end of L-shaped limiting block 12 is aligned with limiting groove 9. Then, the pulling of L-shaped limiting block 12 is released, and the elasticity of spring 17 causes L-shaped limiting block 12 to reset, so that L... One end of the limiting block 12 enters the interior of the limiting groove 9, thereby limiting the telescopic frame 7. The reinforcing frame 16 is slidably connected to the bottom of the telescopic frame 7, and at the same time plays a supporting role on the bottom of the telescopic frame 7, increasing the load-bearing capacity of the telescopic frame 7 and preventing the telescopic frame 7 from warping due to heavy objects. By adjusting the telescopic frame 7, it can flexibly adapt to materials of different lengths, such as pipes and profiles. At the same time, it can provide placement space for more or more scattered materials, such as small components and tool combinations, without the need for additional auxiliary tools to achieve stable load-bearing. The adjustment operation can be completed quickly on the work site without affecting the overall construction rhythm. After the length of the material rack 4 is adjusted, it can still maintain a reliable connection with the main body of the lifting device, ensuring the balance and safety when placing materials and improving the device's adaptability to diverse construction materials.

[0023] Reference Figure 1 - Figure 4 As shown in this embodiment: the bottom of the telescopic frame 7 has two T-shaped grooves 13, and two T-shaped blocks 14 are fixedly connected to both sides of the telescopic groove 6. The surface of the T-shaped blocks 14 is slidably connected to the inside of the T-shaped groove 13. Several rollers 15 are installed at the bottom of the telescopic frame 7. The surface of the rollers 15 is rotatably connected to the bottom of the telescopic groove 6. The top and bottom of the pull rod 11 are provided with sliding grooves 18. The top and bottom of the circular groove 10 away from the telescopic frame 7 are fixedly connected with sliding blocks 19. The surface of the sliding blocks 19 is slidably connected to the inside of the sliding groove 18. Scales 20 are provided at both ends of the telescopic frame 7.

[0024] Specifically: By allowing the T-shaped block 14 to slide inside the T-shaped groove 13, the telescopic frame 7 can move stably inside the telescopic groove 6, preventing the telescopic frame 7 from deviating during movement. At the same time, the rollers 15 at the bottom of the telescopic frame 7 make the adjustment of the telescopic frame 7 smoother and reduce the friction between the telescopic frame 7 and the material rack 4. By allowing the sliding block 19 to slide inside the sliding groove 18, the movement position of the pull rod 11 inside the circular groove 10 can be restricted, allowing the pull rod 11 to drive the L-shaped limit block 12 to accurately enter the limit groove 9, preventing unnecessary displacement of the L-shaped limit block 12. By setting scales 20 at both ends of the telescopic frame 7, the current extension length can be displayed intuitively, helping operators to quickly determine whether the actual usable area of ​​the telescopic plate is suitable for the size of the material to be carried or the required working space, avoiding space waste or insufficient load-bearing capacity due to length estimation errors.

[0025] Working Principle: The motor 5 is started and connected to the lead screw 2 via a belt and gears. The motor 5 drives the lead screw 2 to rotate forward or backward. The rotation of the lead screw 2 causes the sliding nut 3 to slide up and down on its surface. The movement of the sliding nut 3 causes the material rack 4, which is fixedly connected to it, to move. By pulling the L-shaped limiting blocks 12 at both ends of the material rack 4, one end of the L-shaped limiting block 12 moves out of the limiting groove 9. At this time, the telescopic frame 7 is released from its limiting position inside the telescopic groove 6. The telescopic frame 7 can be moved as needed to supplement the length of the material rack 4 and increase its bearing area. After adjustment, one end of the L-shaped limiting block 12 is aligned with the limiting groove 9. Then, the pulling of the L-shaped limiting block 12 is released. The elasticity of the spring 17 causes the L-shaped limiting block 12 to reset, allowing one end of the L-shaped limiting block 12 to enter the limiting groove 9, thereby limiting the telescopic frame 7. The reinforcing frame 16 is slidably connected to the bottom of the telescopic frame 7, which also supports the bottom of the telescopic frame 7, increases the load-bearing capacity of the telescopic frame 7, and prevents the telescopic frame 7 from warping due to heavy objects. By allowing the T-shaped block 14 to slide inside the T-shaped groove 13, the telescopic frame 7 can move stably inside the telescopic groove 6, avoiding deviation during movement. At the same time, rollers 15 are set at the bottom of the telescopic frame 7, which makes the adjustment of the telescopic frame 7 smoother and reduces the friction between the telescopic frame 7 and the material rack 4. By allowing the sliding block 19 to slide inside the sliding groove 18, the movement position of the pull rod 11 inside the circular groove 10 can be restricted, so that the pull rod 11 drives the L-shaped limit block 12 to accurately enter the interior of the limit groove 9, preventing unnecessary displacement of the L-shaped limit block 12. By setting scales 20 at both ends of the telescopic frame 7, the current extension length can be displayed intuitively.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
