[0031] 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.
[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a building construction cargo lifting device, comprising a base 1. Columns 3 are fixedly connected to the left and right sides of the top of the base 1. The columns 3 support and fix the upper components, providing installation positions for a motor 4, a bracket 15, etc. A motor 4 is fixedly connected to the left side of the left column 3. The motor 4 serves as a power source, providing power for the rotation of a rotating shaft 5. The output end of the motor 4 passes through the column 3 and is fixedly connected to the rotating shaft 5. The rotating shaft 5 transmits the rotational power of the motor 4 to a connecting column 6. A connecting column 6 is fixedly connected to the front side of the rotating shaft 5. The connecting column 6 is used to install a sliding block 8 and cooperate with a guide plate 9. A sliding groove 7 is provided on the front side of the connecting column 6, providing a sliding rail for the sliding block 8. The sliding groove 7 restricts the direction of its movement. A sliding block 8 is slidably connected inside the sliding groove 7. The sliding block 8 moves within the sliding groove 7, causing the rotating wheel 17 and the loading mechanism 2 below to change position. A guide plate 9 is fixedly connected to the top of the connecting column 6. The guide plate 9 provides an installation position for the push plate 12 and the telescopic rod 11, and guides the movement of the push plate 12 through the guide groove 10. A guide groove 10 is opened at the bottom of the guide plate 9, guiding the telescopic rod 11 to push the push plate 12 in the direction of movement. A telescopic rod 11 is fixedly connected to the rear side inside the guide groove 10. The telescopic rod 11 pushes the push plate 12 by extending and retracting, thereby controlling the movement of the sliding block 8 within the sliding groove 7. The other end of the telescopic rod 11 is fixedly connected to the push plate 12, which extends... The thrust of the retractor 11 is transmitted to the sliding block 8. The bottom of the push plate 12 is fixedly connected to the top rear side of the sliding block 8, thus pushing the sliding block 8. A take-up roller 13 is fixedly connected to the top rear side of the base 1. The take-up roller 13 is used to take up and release the hoisting rope 18. A motor 2 14 is fixedly connected to the left side of the take-up roller 13. The motor 2 14 provides power for the rotation of the take-up roller 13, thus realizing the take-up and release of the hoisting rope 18. The tops of the two columns 3 are fixedly connected to the same bracket 15. The bracket 15 is used to install the first rotating wheel 16. The inner bottom of the bracket 15 is fixedly connected to the first rotating wheel 16. The first rotating wheel 16 changes the direction of the hoisting rope 18, so that the hoisting rope 18 can be smoothly connected to the second rotating wheel 17. The front side of the sliding block 8 is fixedly connected to the second rotating wheel 17. The second 17 works in conjunction with the first 16 to lift and lower the goods by changing the direction of the lifting rope 18. The output end of the second motor 14 passes through the take-up roller 13 and is fixedly connected to the lifting rope 18. The lifting rope 18 is connected to the goods and lifts and lowers the goods by winding and unwinding. The lifting rope 18 is connected to the outer wall of the first 16 and the second 17 in sequence. The two 16s change the direction of the lifting rope 18 to improve the stability of lifting the goods. The front side of the base 1 is equipped with a loading mechanism 2 for loading goods. The bottom of the front and rear sides of the two columns 3 are fixedly connected with triangular blocks 19. The triangular blocks 19 enhance the stability of the connection between the columns 3 and the base 1 and prevent the device from tilting. The bottom of the multiple triangular blocks 19 are fixedly connected to the top of the base 1 to provide stable support.
[0033] Specifically, when using this building construction cargo lifting device, motor 4 starts, and its output end drives the rotating shaft 5 to rotate within the left column 3. The rotation of the rotating shaft 5 causes the connecting column 6 fixed to its front side to rotate as well. The sliding block 8 on the connecting column 6 can slide within the sliding groove 7. The telescopic rod 11 in the guide groove 10 at the bottom of the guide plate 9 is connected to the push plate 12, which is in turn connected to the rear top of the sliding block 8. When the telescopic rod 11 extends or retracts, it can push the sliding block 8 to reciprocate within the sliding groove 7. Motor 14 starts, driving the take-up roller 13 to rotate, and the suspension rope 18 on the take-up roller 13 moves accordingly. The lifting rope 18 passes sequentially around the first rotating wheel 16 at the bottom inner side of the bracket 15 and the second rotating wheel 17 in front of the sliding block 8. While the first motor 4 rotates the connecting column 6 and the telescopic rod 11 pushes the sliding block 8 to move, the second motor 14 changes the direction of the lifting rope 18 by winding or unwinding the lifting rope 18, using the first rotating wheel 16 and the second rotating wheel 17, thereby realizing the lifting or lowering operation of the goods connected to the end of the lifting rope 18. The triangular block 19 can enhance the stability of the connection between the column 3 and the base 1, distribute the pressure on the column 3, and prevent the column 3 from tilting due to unstable center of gravity or uneven force during the operation of the device.
[0034] Reference Figure 4 and Figure 5The loading mechanism 2 includes a connecting block 201, which connects the lifting rope 18 to the connecting rope 202 below. The top of the connecting block 201 is fixedly connected to the front end of the lifting rope 18, allowing the loading mechanism 2 to move with the lifting rope 18. Multiple connecting ropes 202 are fixedly connected at equal intervals to the outer wall of the connecting block 201. The connecting ropes 202 transmit the movement of the connecting block 201 to the fixed column 203 below. The bottom ends of the multiple connecting ropes 202 are all fixedly connected to the fixed column 203. The fixed column 203 supports the base plate 204 and provides an installation position for the horizontal plate 205. The bottom of the multiple fixed columns 203 is fixedly connected to the same base plate 204. The base plate 204 is used to carry goods and provide a platform for placing goods. The top of one side of the multiple fixed columns 203 is fixedly connected to the horizontal plate 205. The horizontal plate 205 provides an installation base for components such as the moving groove 206 and the clamping plate 207. The bottom of the two horizontal plates 205 are each provided with a moving groove. 206. The moving groove 206 provides a sliding track for the clamping plate 207, which facilitates the adjustment of the clamping distance. The clamping plate 207 is slidably connected to the front and rear sides of the two moving grooves 206. The clamping plate 207 is used to clamp the goods and prevent them from shaking during transportation. Multiple adjustment holes 208 are equidistantly opened on the top of the two horizontal plates 205. The adjustment holes 208 cooperate with the limiters 209 to lock the position of the clamping plate 207. The top left and right sides of the two clamping plates 207 are rotatably connected to the limiters 209. After the limiters 209 are inserted into the adjustment holes 208, the clamping plate 207 can be fixed to ensure stable clamping. The adjacent sides of the two clamping plates 207 are fixedly connected to the pads 23. The pads 23 increase the contact area between the clamping plate 207 and the goods and disperse the clamping force. The adjacent sides of the two pads 23 are fixedly connected to the rubber pads 24 at equal intervals. The rubber pads 24 increase the friction, prevent the goods from sliding and protect the surface of the goods from being scratched.
[0035] Specifically, when it is necessary to fix the goods, the horizontal plate 205 plays a key role. The horizontal plate 205 is fixed to the top of one side of the fixing column 203 and is located in the moving groove 206 at the bottom. The clamping plates 207 on the front and rear sides can slide flexibly. By moving the clamping plates 207, the clamping distance can be adjusted according to the size of the goods. The multiple adjustment holes 208 equidistantly opened on the top of the horizontal plate 205 cooperate with the limiters 209 that are rotatably connected to the left and right sides of the top of the clamping plates 207. When the clamping plate 207 moves to the appropriate position, the limiters 209 are rotated to insert into the corresponding adjustment holes 208, thereby locking the position of the clamping plates 207 and achieving stable clamping of the goods. The pad 23 can increase the contact area between the clamping plates 207 and the goods and disperse the clamping force. The rubber pad 24 increases the friction and prevents the goods from sliding during the clamping process.
[0036] Reference Figure 1 , Figure 3 and Figure 4A switch 20 is fixedly connected to the top front left end of the base 1. The switch 20 serves as an operating control component, providing a convenient operating interface for the operator. The switch 20 is electrically connected to motor 4, telescopic rod 11, and motor 14 respectively. By controlling the on / off state of the control circuit, the start and stop control of motor 4, telescopic rod 11, and motor 14 is achieved. Limit blocks 21 are fixedly connected to the left and right rear ends of the sliding block 8. The limit blocks 21 limit the movement range of the sliding block 8. Limit grooves 22 are opened on the left and right sides of the interior of the connecting column 6. The limit grooves 22 cooperate with the limit blocks 21 to guide the sliding trajectory of the sliding block 8. The limit blocks 21 are slidably connected to the interior of the corresponding limit grooves 22 to ensure that the sliding block 8 slides stably within the specified path and prevents it from detaching. A corresponding baffle 25 is fixedly connected to one side of each of the multiple fixed columns 203. The baffle 25 prevents lateral displacement of goods during transportation. The two baffles 25... The outer walls are all designed with rounded edges to prevent the baffle 25 from scratching the goods or operators. The bottom ends of multiple limiters 209 pass through the corresponding adjustment holes 208. The through-hole action locks the position of the clamping plate 207. The size of the limiter 209 matches the size of the adjustment hole 208 to ensure that the limiter 209 can be accurately inserted into the adjustment hole 208 and play a stable locking role. The baffle 25 can prevent the goods from shifting laterally on the base plate 204 and maintain the stable placement of the goods on the base plate 204. This ensures that the goods are stably placed on the base plate 204 and provides a safe and reliable carrying platform for the goods. After the position of the clamping plate 207 is adjusted, the limiter 209 is rotated to insert into the adjustment hole 208, which can fix the position of the clamping plate 207 and prevent the position of the clamping plate 207 from changing during subsequent operations. This ensures that the clamping plate 207 keeps the goods firmly clamped during the lifting process and completes the lifting operation smoothly.
[0037] Specifically, the operator can turn on or off motor 4, telescopic rod 11 and motor 14 via switch 20, thereby controlling the operation of the cargo lifting device to lift and lower the cargo. It can limit the movement range of sliding block 8 in sliding groove 7, prevent sliding block 8 from coming out of sliding groove 7, and ensure that sliding block 8 maintains a stable sliding trajectory during the rotation of connecting column 6 and the pushing of telescopic rod 11. Baffle 25 can prevent the cargo from shifting laterally on the base plate 204, ensuring that the cargo is stably placed on the base plate 204.
[0038] Working principle: When using this building lifting device, motor 4 starts, and its output end drives the rotating shaft 5 to rotate inside the left column 3. The rotation of the rotating shaft 5 causes the connecting column 6 fixed to its front side to rotate as well. The sliding block 8 on the connecting column 6 can slide in the sliding groove 7. The telescopic rod 11 in the guide groove 10 at the bottom of the guide plate 9 is connected to the push plate 12. The push plate 12 is connected to the rear top of the sliding block 8. When the telescopic rod 11 extends or retracts, it can push the sliding block 8 to reciprocate within the sliding groove 7. When motor 14 starts, it drives the winding roller 13 to rotate. The lifting rope 18 on the winding roller 13 moves accordingly. The lifting rope 18 passes in sequence around the first rotating wheel 16 at the bottom of the inner side of the bracket 15 and the second rotating wheel 17 in front of the sliding block 8. While motor 14 rotates the connecting column 6 and the telescopic rod 11 pushes the sliding block 8 to move, motor 214 changes the direction of the lifting rope 18 by winding or unwinding the lifting rope 18, using the first rotating wheel 16 and the second rotating wheel 17, thereby realizing the lifting or lowering operation of the goods connected to the end of the lifting rope 18.
[0039] Furthermore, when it is necessary to secure the goods, the horizontal plate 205 plays a crucial role. The horizontal plate 205 is fixed to the top of one side of the fixed column 203, and its bottom is in the movable groove 206. The clamping plates 207 on the front and rear sides can slide flexibly. By moving the clamping plates 207, the clamping distance can be adjusted according to the size of the goods. The multiple adjustment holes 208 equidistantly opened on the top of the horizontal plate 205 cooperate with the limiters 209 that are rotatably connected to the left and right sides of the top of the clamping plates 207. When the clamping plate 207 moves to the appropriate position, the limiters 209 are rotated to insert into the corresponding adjustment holes 208, thereby locking the position of the clamping plates 207 and achieving stable clamping of the goods.
