Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an automatic material handling machine for a construction site. Background Art

[0002] Traditional reliance on manual handling on construction sites not only consumes high labor costs, but also has high labor intensity and low work efficiency. With the advancement of modern technology, the level of automation is getting higher and higher. More and more highly automated equipment is entering the construction site and gradually replacing workers in some labor-intensive positions. Therefore, an automated material handling machine for construction sites is needed.

[0003] A Chinese patent discloses a multifunctional rain shield for a transporter (authorization announcement number CN213950002U). The patented technology uses a motor to drive the rain shield to rotate, so that the rain shield is tilted above the control box to block rain. The rain shield can also be rotated downward when loading goods to place materials, killing two birds with one stone.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during use, the existing construction material handling machines cannot be used in different construction sites and working conditions, and thus cannot achieve stability and maneuverability during the handling process, which reduces the adaptability of the handling machine, and cannot accurately grasp and carry construction materials. The operation process is cumbersome, which reduces the user's work efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is that: in the prior art, there is a defect that the transporter cannot be used according to the road conditions of different construction sites when transporting construction materials, thereby affecting the stability and maneuverability during the transportation process. For this reason, we propose an automated material transporter for construction sites.

[0008] Preferably, both sides of the top of the fixed block are fixedly connected to limit plates, and the insides of the limit plates are fixedly connected to the second hydraulic rod.

[0009] Preferably, a pulley is fixedly connected to the front end of the support frame, and the surface of the pulley is slidably connected to the surface of the steel rope.

[0012] Technical effects and advantages of the utility model:

[0013] In the utility model, when the device is started, the building materials are grabbed by the clamping claws. When the grabbing is completed, the first hydraulic rod is retracted, and then the winding wheel is driven by the driving motor to reel in.

[0022] The following is a detailed description of the specific settings and functions of the control mechanism.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment: when the device is started, the clamping claw 11 is used to grab the building materials. When the grabbing is completed, the first hydraulic rod 9 is retracted, and then the winding wheel 6 is driven by the driving motor 5 to reel in. At this time, the steel rope 7 on the surface of the winding wheel 6 is subjected to tension and will be wound on the surface of the winding wheel 6, thereby driving the steel rope 7 to pull the moving plate 8 to move toward the top of the transporter body 1. When it reaches the top of the transporter body 1, it is placed by the extension and contraction of the first hydraulic rod 9. By adopting a chassis 2 structure with multiple wheels and crawlers to provide stability and maneuverability, the ability to adapt to different construction sites and working conditions is improved. At the same time, it is also equipped with a clamping claw 1 1 device, used for grabbing and carrying building materials, is not limited by human fatigue and working hours, and greatly improves work efficiency and production capacity. Both sides of the top of the fixed block 10 are fixedly connected with a fixed plate 12, and the opposite backs of the fixed plate 12 are fixedly connected with a second hydraulic rod 13. The end of the second hydraulic rod 13 away from the fixed plate 12 is fixedly connected to the clamping claw 11. By setting the second hydraulic rod 13, it is convenient to use the second hydraulic rod 13 to control the opening and closing degree of the clamping claw 11, thereby reducing the use cost of the device. Both sides of the top of the fixed block 10 are fixedly connected with a limit plate 14, and the interior of the limit plate 14 is fixedly connected to the second hydraulic rod 13. By setting the limit The positioning plate 14 limits the position of the second hydraulic rod 13 to prevent the position of the second hydraulic rod 13 from being offset and affecting the gripping effect of the clamp 11. The front end of the support frame 3 is fixedly connected with a pulley 15, and the surface of the pulley 15 is slidably connected to the surface of the steel rope 7. By setting the pulley 15, when the driving motor 5 drives the winding wheel 6 to rotate and drives the steel rope 7 to move, it plays an auxiliary movement role. Guide grooves 16 are provided on both sides of the inner wall of the extension frame 4, and guide blocks 17 are slidably connected inside the guide grooves 16. The facing surfaces of the guide blocks 17 are fixedly connected to the two sides of the moving plate 8. By setting the structure of the guide grooves 16 and the guide blocks 17, the moving plate 8 can be moved. The plate 8 slides along the direction of the guide groove 16 to prevent the movement trajectory of the moving plate 8 from being offset. A shock-absorbing spring 19 is fixedly connected to the top of the transporter body 1. There are four shock-absorbing springs 19 and they are evenly distributed around the top of the transporter body 1. The end of the shock-absorbing spring 19 away from the transporter body 1 is fixedly connected to the placement plate 18. By setting the structure of the placement plate 18 and the shock-absorbing spring 19, when the clamp 11 places the grasped building materials on the surface of the placement plate 18, in order to prevent the building materials from being damaged, the shock-absorbing spring 19 is set and the force of the shock-absorbing spring 19 is used to dampen the building materials, thereby improving the practicability of the device.

[0024] The working principle of the utility model is that when the device is started, the clamping claw 11 is used to grab the building materials. When the grabbing is completed, the first hydraulic rod 9 is retracted, and then the winding wheel 6 is driven by the driving motor 5 to reel in. At this time, the steel rope 7 on the surface of the winding wheel 6 is subjected to tension and will be wound on the surface of the winding wheel 6, thereby driving the steel rope 7 to pull the moving plate 8 to move to the top of the transporter body 1. When it reaches the top of the transporter body 1, it is placed by the extension and contraction of the first hydraulic rod 9. By adopting a chassis 2 structure with multiple wheels and crawlers to provide stability and maneuverability, the ability to adapt to different construction sites and working conditions is improved. At the same time, it is also equipped with a clamping claw 11 device for grabbing and transporting building materials, which is not limited by human fatigue and working hours, and greatly improves work efficiency and production capacity. By setting a second hydraulic rod 13, it is convenient to use the second hydraulic rod 13 to The opening and closing degree of the clamping jaw 11 is controlled, thereby reducing the use cost of the device. By setting a limit plate 14, the position of the second hydraulic rod 13 is limited to prevent the position of the second hydraulic rod 13 from being offset and affecting the gripping effect of the clamping jaw 11. By setting a pulley 15, when the driving motor 5 drives the winding wheel 6 to rotate and drives the steel rope 7 to move, it plays an auxiliary movement role. By setting the structure of the guide groove 16 and the guide block 17, the movable plate 8 slides along the direction of the guide groove 16, thereby preventing the movement trajectory of the movable plate 8 from being offset. By setting the structure of the placement plate 18 and the shock-absorbing spring 19, when the clamping jaw 11 places the grabbed building materials on the surface of the placement plate 18, in order to prevent the building materials from being damaged, by setting the shock-absorbing spring 19, the building materials are damped by the force of the shock-absorbing spring 19, thereby improving the practicability of the device.
