When the device needs to be used to feed concrete, the placement box is first placed on the top of the air bag, and then the concrete is poured into the placement box. After the concrete is poured into the placement box, the increased weight squeezes the air bag, so that the gas in the air bag enters the air pipe, and the gas entering the air pipe pushes the clamping rod into the clamping groove. The clamping rod enters the clamping groove to limit the placement box.

[0013] A concrete construction engineering feeding device and a feeding method thereof, comprising the following steps:

[0014] S1: Start the driving motor to drive the threaded rod to rotate. The threaded rod is threadedly connected to the lifting block, and then the threaded rod drives the lifting block to move upward.

[0015] S2: As the lifting block moves upward, the piston rod is driven upward through the fixed plate, so that the piston rod slides in the cylinder and squeezes the liquid in the cylinder;

[0016] S3: When the counterweight block moves outward, the counterweight block pulls the drawstring, causing the drawstring to pull the connecting plate. The connecting plate rotates with the fixed block as the midpoint after receiving the pulling force of the drawstring.

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention aims to solve the problem that as the height of concrete rises, the wind-receiving area of ​​the feeding device increases accordingly. When the lifting block 1 moves upward, the piston rod is driven to move upward through the fixed plate, so that the piston rod slides in the cylinder and squeezes the liquid in the cylinder. In this way, the liquid in the cylinder can enter the telescopic tube 1 through the air outlet pipe, thereby forcing the telescopic tube 1 to expand. After the expansion of the telescopic tube 1, the counterweight block is driven to move outward. In this way, the force-bearing area at the bottom of the feeding device is increased, and the possibility of the feeding device tilting or collapsing during the feeding process is reduced. By increasing the force-bearing area at the bottom, the feeding device can more effectively bear the weight and pressure during the rising process, and reduce the risk of tilting or collapse caused by unstable center of gravity or insufficient bearing capacity.

[0019] 2. When the device of the present invention is needed to load concrete, first place the placement box on the top of the airbag, and then pour the concrete into the placement box. After the concrete is poured into the placement box, the increased weight squeezes the airbag, causing the gas in the airbag to enter the air pipe. The gas entering the air pipe pushes the clamping rod into the clamping groove. The clamping rod enters the clamping groove to limit the placement box. This design effectively prevents external vibration or wind from interfering with the concrete, ensures that the concrete will not tilt or fall, and thus improves work safety.

[0020] 3. The present invention starts a driving motor to drive the threaded rod to rotate, and the threaded rod is threadedly connected to the lifting block one, and then the threaded rod drives the lifting block one to move upward. When the lifting block one moves upward, the pulley one follows the lifting block one to move upward, and the limiting block one limits the transmission belt one, thereby forcing the transmission belt one to drive the lifting block two to move upward. After the lifting block two moves upward, it is restricted by the limiting block two, thereby forcing the transmission belt two to drive the lifting block three to move upward. The lifting block three moves upward to raise the concrete in the placement box to a specified position, thereby completing the loading of the concrete and transporting the concrete from the ground or a low place to a high place. This can avoid manual handling and the use of traditional lifting equipment, save time and labor costs, accurately control the loading speed and position of the concrete, ensure that the concrete is accurately delivered to the target position, and improve the accuracy and quality of the construction.

[0021] 4. In the present invention, when the counterweight block moves outward, the counterweight block pulls the pull rope, which causes the pull rope to pull the connecting plate. After the connecting plate is subjected to the pulling force of the pull rope, it rotates with the fixed block as the midpoint, thereby driving the ground nails at the bottom of the rotating plate to be inserted into the ground. In this way, the ground nails can increase the lateral support force of the loading device, making the loading device more stable during the loading process. The insertion of the ground nails not only provides lateral support force, but also provides additional stability when the device is subject to additional challenges or uneven ground conditions, thereby increasing the lateral support force and overall stability of the device.

[0040] For example 2, please refer to Figure 4 - Figure 8 The present invention is a feeding device for concrete construction projects. Based on Example 1, the counterweight mechanism 2 also includes a connecting block 204 fixedly connected to the top of the counterweight block 203, and a telescopic tube 205 is fixedly connected to the side wall of the main body 101. The end of the telescopic tube 205 away from the main body 101 is fixedly connected to the connecting block 204.

After the expansion of the telescopic tube 202, the counterweight block 203 moves outward, which can increase the force-bearing area at the bottom of the feeding device and reduce the possibility of the feeding device tilting or collapsing during the feeding process. By increasing the force-bearing area at the bottom, the feeding device can more effectively withstand the weight and pressure during the rising process, reducing the risk of tilting or collapse caused by unstable center of gravity or insufficient carrying capacity.

[0042] The fixing mechanism 3 also includes a return spring 304 fixedly connected to the bottom of the rotating plate 302, and one end of the return spring 304 away from the rotating plate 302 is fixedly connected to the outer wall of the main body 101, a connecting plate 305 is fixedly connected to the side wall of the rotating plate 302, a guide block 306 is fixedly connected to the side wall of the main body 101, and a pull rope 307 is fixedly connected to the top of the connecting plate 305.

After being pulled by the pull rope 307, the connecting plate 305 rotates with the fixed block 301 as the midpoint, thereby driving the ground nails 303 at the bottom of the rotating plate 302 to be inserted into the ground. In this way, the ground nails 303 can increase the lateral support force of the loading device, making the loading device more stable during the loading process. The insertion of the ground nails 303 not only provides lateral support force, but also provides additional stability when the device is subject to additional challenges or uneven ground conditions, thereby increasing the lateral support force and overall stability of the device.

[0044] S1: Start the driving motor 102 to drive the threaded rod 103 to rotate. The threaded rod 103 is threadedly connected with the lifting block 104, and then the threaded rod 103 drives the lifting block 104 to move upward.

[0045] S2: When the lifting block 104 moves upward, the piston rod 208 is driven to move upward through the fixed plate 207, so that the piston rod 208 slides in the cylinder 206 to squeeze the liquid in the cylinder 206;

After receiving the pulling force of the pull rope 307, the connecting plate 305 rotates with the fixed block 301 as the midpoint.

[0047] A specific application of this embodiment is:

[0048] When the device is needed to load concrete, first place the placement box 119 on the top of the air bag 118, and then pour the concrete into the placement box 119. After the concrete is poured into the placement box 119, the increased weight squeezes the air bag 118, so that the gas in the air bag 118 enters the air pipe 121. The gas entering the air pipe 121 pushes the clamping rod 122 into the clamping groove 120. The clamping rod 122 enters the clamping groove 120 to limit the placement box 119. This can prevent the concrete from being affected by external vibration or wind during the loading process, and can ensure that the concrete is in the loading process. There will be no tilting or falling. After limiting the placement box 119, the drive motor 102 is started to drive the threaded rod 103 to rotate. The threaded rod 103 is threadedly connected with the lifting block 104, and then the threaded rod 103 drives the lifting block 104 to move upward. When the lifting block 104 moves upward, the pulley 108 moves upward with the lifting block 104. The limiting block 110 limits the transmission belt 109, thereby forcing the transmission belt 109 to drive the lifting block 2 111 to move upward. After the lifting block 2 111 moves upward, it is limited by the limiting block 2 116, thereby forcing the transmission belt 2 11 4 drives the lifting block 3 115 to move upward, and the lifting block 3 115 moves upward to raise the concrete in the placing box 119 to the specified position, thereby completing the concrete feeding work. As the height of the concrete rises, the wind receiving area of ​​the feeding device also increases. When the lifting block 104 moves upward, the piston rod 208 is driven to move upward through the fixing plate 207, so that the piston rod 208 slides in the cylinder 206 and squeezes the liquid in the cylinder 206, so that the liquid in the cylinder 206 can enter the telescopic tube 1 202 through the air outlet pipe 209, thereby forcing the telescopic tube 1 202 to expand and the telescopic tube 202 to expand. After the shrink tube 202 expands, it drives the counterweight block 203 to move outward, which can increase the force-bearing area at the bottom of the loading device and reduce the possibility of the loading device tilting or collapsing during the loading process. While the counterweight block 203 moves outward, the counterweight block 203 pulls the pull rope 307, so that the pull rope 307 pulls the connecting plate 305. After the connecting plate 305 is pulled by the pulling force of the pull rope 307, it rotates with the fixed block 301 as the midpoint, thereby driving the ground nail 303 at the bottom of the rotating plate 302 to be inserted into the ground. In this way, the ground nail 303 can increase the side support force of the loading device, making the loading device more stable during the loading process.
