Description

Technical Field

[0001] This invention relates to the field of concrete placing boom technology, specifically to a tower-type multi-stage lifting concrete placing boom and its usage method. Background Technology

[0002] A concrete placing boom is a device that transports concrete to a designated location. Concrete placing booms are generally used to transport concrete to locations at different heights, so it is necessary to install a lifting mechanism on the concrete placing boom.

[0003] The existing defects of fabric placing machines are:

[0004] 1. The prior art US4477065A discloses a concrete placing boom conveyor belt conveyor. This technology does not have a structure for adjusting the height of the concrete placing boom structure, nor can it fix the temperature of the height-adjustable concrete placing boom. It is inconvenient to place concrete on buildings of different heights. Therefore, a tower-type multi-stage lifting concrete placing boom that can be raised and lowered and ensures the stability of the structure after being raised is needed to solve this problem.

[0005] 2. Existing technology KR1020070064607A discloses a suspended conveying device. This technology does not have a structure to limit the height of the raised structure. After the extension height of the concrete placing boom increases, the support part is easily subjected to a larger bending moment, which causes the support part to bend under bending force for a long time. Therefore, the support part is not easy to replace after bending. Therefore, a tower-type multi-stage lifting concrete placing boom with a structure that can limit the bending of the support part and is easy to replace is needed to solve this problem.

[0006] 3. Existing technology EP2597059A1 discloses a suspended conveyor, which does not have an anti-tipping structure. When the placing boom moves to an inclined ground, if the weight of the material on the placing boom is too heavy, it is easy to cause the center of gravity of the placing boom to become unstable and the placing boom to tip over. Therefore, a tower-type multi-stage lifting concrete placing boom that can flexibly support the placing boom to prevent it from tipping over is needed to solve this problem.

[0007] 4. Existing technology CN115126246A discloses a wheeled concrete placing boom, which does not have an anti-tipping structure. When an anti-tipping structure is installed on the outside of the equipment, the anti-tipping structure generally provides support by contacting the anti-tipping structure with the ground. However, the ground is often uneven, and the anti-tipping structure is not easy to make complete contact with the ground on uneven or sloping ground, resulting in insufficient friction on the contact surface and easy slippage. Therefore, a tower-type multi-stage lifting concrete placing boom that can adjust the angle of the anti-tipping structure that contacts the ground to facilitate complete contact with the ground is needed to solve this problem. Summary of the Invention

[0008] One objective of this application is to provide a tower-type multi-stage lifting concrete placing machine and its usage method, which can solve the technical problems raised in the prior art.

[0012] Preferably, a plurality of bolts are installed through one side of the first rod, and one end of the bolts penetrates one side of the second rod. A nut is installed on the outside of the bolts, and the nut is located on one side of the second rod.

[0013] Preferably, the anti-bending mechanism includes a connecting frame, two bolts, two lifting plates, six hydraulic telescopic units, and one limiting plate. The connecting frame is installed on the outside of the piston rod. Two bolts are installed through the front of the connecting frame, and one end of the two bolts penetrates the front of the piston rod. Two lifting plates are installed on one side of the connecting frame. Six hydraulic telescopic units are symmetrically installed on one side of the lifting plates.

[0014] Preferably, the anti-bending mechanism further includes a plate body three, a hydraulic telescopic unit seven, and a limiting plate two. The two plate bodies three are respectively installed on the front and back of the lifting plate body one.

[0016] Preferably, a guide frame 2 is installed at one end of the rotating rod 1, a support rod is movably installed on the inner side of the guide frame 2, a plurality of fitting holes are opened through the front of the support rod, and a bolt 4 is installed through the front of the guide frame 2.

Connecting rods are symmetrically installed on both sides of the second rotating rod, and a movable plate is installed at the bottom of the connecting rod. Multiple insert rods are installed at the bottom of the movable plate.

[0018] Preferably, the tower-type multi-stage lifting concrete placing boom is used as follows:

[0019] S1. Hydraulic telescopic unit one drives frame two to move upward, hydraulic telescopic unit two drives frame three to move upward, hydraulic telescopic unit three drives frame four to move upward, and hydraulic telescopic unit four drives lifting plate one to move upward, thereby causing the fabric truss and the loading truss to move upward.

[0020] S2. The hydraulic telescopic unit five drives the lifting plate two to move upward. Then, the hydraulic telescopic unit six drives the limiting plate one to limit the two sides of the frame four. Then, the hydraulic telescopic unit six drives the limiting plate two to limit the front and rear of the frame four.

[0021] Preferably, step S2 further includes the following steps:

[0022] S21. Adjust the position of the moving rod as needed, then rotate the support rod body, and then insert the insertion rod into the ground, so as to support the equipment from different directions to prevent it from tipping over.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention, by setting up a multi-stage lifting structure, enables the equipment to place concrete on buildings of different heights. By moving the second, third, and fourth frames and the lifting plate upwards, the concrete placement truss and the material feeding truss can be raised to different heights, thereby placing concrete on buildings of different heights.

[0025] 2. In this invention, the hydraulic telescopic unit five drives the lifting plate two to move upward, and then the hydraulic telescopic unit six drives the limiting plate one to limit the two sides of the frame four. Then, the hydraulic telescopic unit six drives the limiting plate two to limit the front and rear of the frame four. This reduces the possibility that the frame four, frame three, frame two and frame one may be damaged by bending force due to the weight of the cloth truss and the feeding truss when the height of the equipment is increased. In addition, the guide frame one can be disassembled, and it is easy to replace the limiting plate two, the limiting plate one, the lifting plate two or the guide frame one after damage.

[0026] 3. The present invention can support the device by setting a support rod, thereby reducing the possibility of the device tipping over. The position of the support rod can be adjusted by moving the rod back and forth. At the same time, the support rod can rotate, so that the support rod can support the device at different positions and at different angles.

[0027] 4. The present invention can make the movable plate rotate relative to the supporting rod by setting a rotating rod, a connecting rod and a movable plate. This allows the movable plate to rotate and make stable contact with the ground on ground with different inclinations when the ground is uneven. This makes it easy to insert the insertion rod into ground with different slopes. Attached Figure Description
