Description

Technical Field

[0001] This utility model relates to the field of building material lifting, specifically a building material lifting device for construction projects. Background Technology

[0002] Material hoisting in construction engineering refers to the process of transporting building materials (such as bricks, concrete, steel bars, etc.) from the ground or low places to the required construction height using mechanical equipment. Its core lies in using vertical transportation equipment to replace manual handling, which significantly improves construction efficiency, reduces labor costs, and has a positive impact on the economic benefits of construction projects.

[0003] In existing technologies, construction materials often need to be lifted to a suitable height for use and assembly, making them easier for workers to handle. To reduce workload and the risk of accidents while carrying materials, elevators or cranes are typically used. While these devices are effective, they require placing the materials on top of the equipment and moving them upwards to the workers at a higher position. After use, the materials are lowered and reloaded, a process that takes considerable time. This means workers at higher positions must wait a long time before construction can resume, significantly reducing construction efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, when lifting materials, the materials need to be placed on top of the equipment and moved upwards to the side of the workers at a higher position. After the materials are used up, they are moved downwards again for reloading. However, the process of moving downwards and reloading takes a long time. As a result, the workers at the higher position have to wait a long time after using the materials before they can resume construction, which greatly reduces the efficiency of construction and building projects. This utility model proposes a building material lifting device for building engineering.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a building material lifting device for construction engineering, including a base plate, a connecting plate fixedly connected to the top of the base plate, an installation frame fixedly connected to the top of the connecting plate, two installation frames are provided, a placement box is provided on the top of each of the two installation frames, and a lifting mechanism and a driving component are provided on the top of the base plate, and two lifting mechanisms are provided. The lifting mechanism includes a fixed block, the top of which is fixedly connected to the bottom of the mounting frame. A first connecting rod is rotatably connected to one side of the fixed block. A first rotating plate is fixedly connected to the surface of the first connecting rod. A second connecting rod is rotatably connected to the inner cavity of the first rotating plate. A second rotating plate is rotatably connected to the surface of the second connecting rod. A fixed shaft is rotatably connected to the inner cavity of the second rotating plate. One end of the fixed shaft is fixedly connected to one side of the placement box. A driven gear is provided on the top of the base plate. A transmission shaft is fixedly connected to one side of the driven gear. A rotating block is fixedly connected to one end of the transmission shaft. An adjusting component is provided on one side of the rotating block. A pushing block is provided on one side of the adjusting component. A push rod is fixedly connected to one side of the pushing block. A fixed frame is fixedly connected to one side of the first rotating plate. The surface of the push rod is slidably connected to the inner cavity of the fixed frame. A limit component, an adjusting component, and a support component are provided on the top of the base plate.

[0006] Preferably, the drive assembly includes a mounting plate, the bottom of which is fixedly connected to the top of a base plate. A torque motor is fixedly connected to the inner cavity of the mounting plate, and a drive gear is fixedly connected to the output end of the torque motor. The teeth of the drive gear mesh with the teeth of the driven gear.

[0007] Preferably, the adjusting assembly includes a screw, one end of which is rotatably connected to one side of the pushing block, the surface of which is threadedly connected to the inner cavity of the rotating block, and a sliding plate fixedly connected to one side of the pushing block, the surface of which is slidably connected to the inner cavity of the rotating block.

[0008] Preferably, the limiting component includes a sliding block, one side of which is fixedly connected to one side of the placement box, and a fixing rod is fixedly connected to the top of the mounting bracket, with the inner cavity of the sliding block slidably connected to the surface of the fixing rod.

[0009] Preferably, the support assembly includes a fixing plate, the bottom of which is fixedly connected to the top of the base plate, an arc-shaped block is fixedly connected to one side of the fixing plate, and a hollow ring block is fixedly connected to one side of the driven gear. The surface of the arc-shaped block is slidably connected to the inner cavity of the hollow ring block.

[0010] Preferably, a first reinforcing ring block is fixedly connected to one side of the placement box, the inner cavity of the first reinforcing ring block is fixedly connected to the surface of the fixed shaft, a limit slider is fixedly connected to one side of the fixed shaft, and a second reinforcing ring block is fixedly connected to one side of the driven gear, the inner cavity of the second reinforcing ring block is fixedly connected to the surface of the transmission shaft.

[0011] Preferably, a reinforcing block is fixedly connected to the top of the base plate, and the inner cavity of the reinforcing block is fixedly connected to the surface of the fixing rod.

[0012] The advantages of this utility model are: This invention utilizes the operation of a torque motor and the meshing relationship between the driven and driving gears to smoothly drive a single driven gear to move. The rotation of the driven gear simultaneously drives two push rods to rotate eccentrically, allowing both first rotating plates to rotate around the center of the fixed block connected to their inner cavities. This achieves synchronous pushing of the two placement boxes. Since the two rotating blocks move in opposite directions, when one placement box moves upward, the other will move downward. This allows one placement box to lift materials while the other moves downward, and enables workers at a higher position to access materials from one of the placement boxes. In use, another placement box can be filled by workers at a lower position, effectively improving the efficiency of lifting building materials. This solves the problem that when lifting materials, it is necessary to first place the materials on the top of the equipment and move them upwards to the side of the workers at a higher position. After the materials are used up, they are moved downwards to be filled again. However, the process of moving downwards and filling takes a long time. As a result, the workers at a higher position have to wait a long time after using the materials before they can start construction again, which greatly reduces the efficiency of building construction and building projects.

Detailed Implementation

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a construction material lifting device for building engineering. (Refer to...) Figure 1 and Figure 5 A construction material lifting device for construction engineering includes a base plate 1, a connecting plate 2 fixedly connected to the top of the base plate 1, an mounting frame 3 fixedly connected to the top of the connecting plate 2, two mounting frames 3 are provided, and a placement box 4 is provided on the top of each of the two mounting frames 3. A lifting mechanism 5 and a drive assembly 6 are provided on the top of the base plate 1, and two lifting mechanisms 5 are provided. The lifting mechanism 5 includes a fixed block 501, the top of which is fixedly connected to the bottom of the mounting frame 3. A first connecting rod 502 is rotatably connected to one side of the fixed block 501. A first rotating plate 503 is fixedly connected to the surface of the first connecting rod 502. A second connecting rod 504 is rotatably connected to the inner cavity of the first rotating plate 503. A second rotating plate 505 is rotatably connected to the surface of the second connecting rod 504. A fixed shaft 510 is rotatably connected to the inner cavity of the second rotating plate 505. One end of the fixed shaft 510 is fixedly connected to one side of the placement box 4. A driven mechanism is provided on the top of the base plate 1. Gear 511, driven gear 511 is fixedly connected to one side of transmission shaft 512, transmission shaft 512 is fixedly connected to one end of rotating block 513, rotating block 513 is provided on one side of adjustment component 508, adjustment component 508 is provided on one side of push block 514, push block 515 is fixedly connected to one side of push block 514, first rotating plate 503 is fixedly connected to one side of fixed frame 507, push rod 515 is slidably connected to inner cavity of fixed frame 507, and bottom plate 1 is provided with limit component 506, adjustment component 508 and support component 509.

[0018] The base plate 1 can be connected to the mounting frame 3 via the connecting plate 2. There are two lifting mechanisms 5 on the top of the base plate 1, and the two lifting mechanisms 5 have the same structure. At the same time, there are two placement boxes 4. The two lifting mechanisms 5 correspond one-to-one with the two placement boxes 4. This allows the drive assembly 6 to smoothly drive the two placement boxes 4 to move up and down synchronously when the lifting mechanism 5 is in operation. The two placement boxes 4 move in opposite directions. When one placement box 4 moves upward, the other placement box 4 moves downward. This allows one placement box 4 to lift materials while the other placement box 4 moves downward. When one placement box 4 is used by workers at a higher position, the other placement box 4 can be filled by workers at a lower position. Meanwhile, the mounting frame 3 can be connected to the first connecting rod 502 via the fixing block 501. The first rotating plate 503 connected to the surface of the first connecting rod 502 can smoothly connect and install the second rotating plate 505 through its connection with the second connecting rod 504. Furthermore, the fixed shaft 510 connected to one side of the placement box 4 can be smoothly connected to the second rotating plate 505. This allows the placement box 4 to be smoothly pushed by the second connecting rod 504 and the second rotating plate 505 when the first rotating plate 503 rotates around the center of the first connecting rod 502. This enables the placement box 4 to move vertically smoothly. At the same time, the transmission shaft 512 connected to one side of the driven gear 511 can connect to the pushing block 514 through the rotating block 513 and the adjusting component 508. The push rod 515 installed on one side of the pushing block 514 can rotate eccentrically around the center of the driven gear 511 when the rotating block 513 rotates. Then, by utilizing the connection between the push rod 515 and the fixed frame 507, it can push the first rotating plate 503, thereby realizing the height adjustment of the placement box 4.

[0019] Additional explanation: It should be noted that there is only one driven gear 511 in the lifting mechanism 5, while there are two in the other structures. The two rotating blocks 513 are in opposite directions, which makes the two second connecting rods 504 also in opposite directions, thus effectively achieving the reverse pushing of the two placement boxes 4.

[0020] Reference Figure 2 and Figure 4 The drive assembly 6 includes a mounting plate 601, the bottom of which is fixedly connected to the top of the base plate 1. A torque motor 602 is fixedly connected to the inner cavity of the mounting plate 601. A drive gear 603 is fixedly connected to the output end of the torque motor 602. The teeth of the drive gear 603 mesh with the teeth of the driven gear 511. The base plate 1 can install and fix the torque motor 602 through the mounting plate 601. The torque motor 602 can connect to the drive gear 603. When the torque motor 602 is in operation, it can smoothly drive the drive gear 603 to rotate. At the same time, the diameter of the drive gear 603 is smaller than the diameter of the driven gear 511, and the number of teeth on the surface of the drive gear 603 is smaller than the number of teeth on the driven gear 511. This allows the torque motor 602 to effectively increase the torque of the driven gear 511 when rotating through its own operation and the way the small gear drives the large gear. This makes the placement box 4 more stable and smooth when moving up and down.

[0021] Reference Figure 6The adjusting component 508 includes a screw 5081, one end of which is rotatably connected to one side of the pushing block 514. The surface of the screw 5081 is threadedly connected to the inner cavity of the rotating block 513. A sliding plate 5082 is fixedly connected to one side of the pushing block 514. The surface of the sliding plate 5082 is slidably connected to the inner cavity of the rotating block 513. The rotating block 513 can be connected to the pushing block 514 via the screw 5081. The arrangement of the screw 5081 and the sliding plate 5082 allows the rotating block 513 to smoothly drive the pushing block 514 and the push rod 515 to rotate eccentrically when it rotates. When the screw 5081 is rotated, it can drive the pushing block 514 to move. This allows the operator to adjust the position of the pushing block 514 and the push rod 515 to adjust the rotation range of the first rotating plate 503 and the height of the placement box 4, so that the placement box 4 can rise to a greater range.

[0022] Reference Figure 1 and Figure 2 The limiting component 506 includes a sliding block 5061, one side of which is fixedly connected to one side of the placement box 4. A fixing rod 5062 is fixedly connected to the top of the mounting frame 3. The inner cavity of the sliding block 5061 is slidably connected to the surface of the fixing rod 5062. The mounting frame 3 can install and fix the fixing rod 5062, while the placement box 4 can connect to the sliding block 5061. When the placement box 4 is pushed, the fixing rod 5062 can smoothly limit the sliding block 5061 and the placement box 4, so that the placement box 4 can move more stably when pushed, and is less likely to deviate, tilt or shake during movement.

[0023] Reference Figure 2 and Figure 3 The support assembly 509 includes a fixing plate 5091, the bottom of which is fixedly connected to the top of the base plate 1. An arc-shaped block 5093 is fixedly connected to one side of the fixing plate 5091, and a hollow ring block 5092 is fixedly connected to one side of the driven gear 511. The surface of the arc-shaped block 5093 is slidably connected to the inner cavity of the hollow ring block 5092. The base plate 1 can install and fix the arc-shaped block 5093 through the fixing plate 5091. The sliding connection between the hollow ring block 5092 and the arc-shaped block 5093 allows the driven gear 511 to be effectively supported and limited by the arc-shaped block 5093 when it rotates, thereby improving the stability of the arc-shaped block 5093 during rotation and making it less likely to fall off. At the same time, the two support assemblies 509 are respectively arranged on both sides of the driven gear 511, which effectively improves the effect of limiting and supporting the driven gear 511.

[0024] Reference Figure 3 and Figure 5A first reinforcing ring block 8 is fixedly connected to one side of the placement box 4. The inner cavity of the first reinforcing ring block 8 is fixedly connected to the surface of the fixed shaft 510. A limit slider 7 is fixedly connected to one side of the fixed shaft 510. A second reinforcing ring block 9 is fixedly connected to one side of the driven gear 511. The inner cavity of the second reinforcing ring block 9 is fixedly connected to the surface of the transmission shaft 512. The first reinforcing ring block 8 can reinforce and strengthen the connection between the placement box 4 and the fixed shaft 510 through its connection with the placement box 4 and the fixed shaft 510. This design prevents the connection between the placement box 4 and the fixed shaft 510 from breaking or shaking. At the same time, the setting of the limiting slider 7 prevents the second rotating plate 505 from sliding off or falling off the surface of the fixed shaft 510 when it rotates on the surface of the fixed shaft 510. The second reinforcing ring block 9 can strengthen and reinforce the connection between the driven gear 511 and the transmission shaft 512 through its connection with the driven gear 511 and the transmission shaft 512, thereby effectively reinforcing the rotation of the rotating block 513.

[0025] Reference Figure 1 and Figure 2 A reinforcing block 10 is fixedly connected to the top of the base plate 1. The inner cavity of the reinforcing block 10 is fixedly connected to the surface of the fixing rod 5062. The setting of the reinforcing block 10 can effectively strengthen the fixing rod 5062, so that while the fixing rod 5062 limits the sliding block 5061, the fixing rod 5062 itself has high and strong stability and is not easy to shake or tilt during use.

[0026] Working Principle: When using this device, the operator first places the material into the placement box 4 located at the bottom. Then, by starting the torque motor 602, the operator drives the drive gear 603 to rotate. Since the drive gear 603 meshes with the driven gear 511 and the number of teeth of the drive gear 603 is less than that of the driven gear 511, a speed reduction and torque increase transmission is formed, driving the driven gear 511 to rotate stably. The rotation of the driven gear 511 is transmitted to the rotating block 513 through the fixedly connected transmission shaft 512. The inner cavity of the rotating block 513 is connected to the pushing block 514 through a threaded screw 5081 and a sliding plate 5082, causing the push rod 515 fixed to the pushing block 514 to rotate eccentrically around the center of the driven gear 511. When the push rod 515 rotates, it can push the first rotating plate 503 to rotate around the axis of the first connecting rod 502. The first rotating plate 503 rotates through the inner cavity... The second connecting rod 504 drives the second rotating plate 505 to rotate. The second rotating plate 505 then pushes and pulls the placement box 4 through the fixed shaft 510 connected to the inner cavity, realizing the vertical lifting and lowering of the placement box 4. At the same time, since the two rotating blocks 513 are in opposite directions, they will drive the two second connecting rods 504 to move in opposite directions, so that the two placement boxes 4 always move in opposite directions synchronously, and maintain the state that one placement box 4 rises and the other placement box 4 falls. The placement box 4 slides stably with the fixed rod 5062 fixed to the top of the mounting frame 3 through the fixed sliding block 5061. Thus, when the placement box 4 filled with material moves upward, the other placement box 4 without material will move downward. When one placement box 4 is used by the staff at the higher position, the other placement box 4 can be filled by the staff at the lower position, thus repeating the cycle and effectively improving the efficiency of lifting building materials.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
