[0002] The hanging basket construction, also known as the construction hanging basket, is a major piece of equipment used in the segmented construction of prestressed concrete continuous beams, T-shaped steel structures, and cantilever beams. It can move forward as a whole along the track. Hanging basket construction can use various techniques such as truss hanging basket, triangular hanging basket, prismatic hanging basket, and inclined hanging basket, and it is most widely used in bridge construction.

[0003] During the process of concrete pouring using a hanging basket, the direct impact of the discharge port on the formwork or reinforcing steel frame can easily cause concrete segregation. Concrete segregation can lead to defects such as surface sand marks, exposed aggregates, and exposed reinforcing steel, affecting the density of the concrete. Utility Model Content

[0004] This utility model discloses a truss-type hanging basket cantilever structure, which aims to solve the technical problem that in the existing device, the direct impact of the discharge port on the formwork or steel reinforcement cage during the cantilever process easily causes concrete segregation, affecting the density of the concrete.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Two electric telescopic rods are fixedly connected to the bottom of the connecting frame, and the output ends of the two electric telescopic rods are fixedly connected to the same buffer discharge bin. The inner wall of the buffer discharge bin is... A certain slope is present, and a feeding hole is opened at the bottom of the buffer feeding hopper; an arc-shaped bend is fixedly connected inside the feeding hole, a control valve is provided on the outer wall of the arc-shaped bend, and a feeding trough is provided on the outer wall of the arc-shaped bend; two gripping parts are fixedly connected to the outer wall of the feeding trough, and two mounting plates are fixedly connected to the outer wall of the feeding trough.

Two electric telescopic rods 606 are fixedly connected to the bottom of the connecting frame 603. The output ends of the two electric telescopic rods 606 are fixedly connected to the same buffer discharge bin 604. The inner wall of the buffer discharge bin 604 presents… A certain slope and a feeding hole are provided at the bottom of the buffer feeding hopper 604; an arc-shaped bend 612 is fixedly connected inside the feeding hole, a control valve 605 is provided on the outer wall of the arc-shaped bend 612, and a feeding groove 610 is provided on the outer wall of the arc-shaped bend 612; two gripping parts 609 are fixedly connected to the outer wall of the feeding groove 610, and two mounting plates 611 are fixedly connected to the outer wall of the feeding groove 610.

[0020] Working principle:

[0021] During pouring, the sliding frame 3 slides on the laid track 2. After sliding to the designated position, it delivers the concrete into the buffer discharge hopper 604. The electric telescopic rod 606 is opened, and the height of the buffer discharge hopper 604 is adjusted to a suitable position. Then, the electric telescopic rod 606 is closed, and the control valve 605 and vibrator 608 are opened simultaneously. The concrete is discharged through the arc-shaped bend 612 and the discharge chute 610. The hydraulic push rod 607 is activated, which can push the buffer discharge hopper 604 to move horizontally. By adjusting the position of the buffer discharge hopper 604, segregation can be avoided due to excessive impact force during concrete discharge caused by excessive height during pouring. The gripper 609 facilitates the work of construction personnel. The curved bend 612 can change the direction of concrete spraying during pouring and reduce the spraying speed of concrete, avoiding concrete segregation caused by direct impact on the formwork or steel reinforcement. This helps to improve the density of the concrete. At the same time, a vibrator 608 is installed to vibrate the discharge chute 610 and the curved bend 612, preventing concrete from accumulating on the curved bend 612 and the discharge chute 610, which would block the equipment and affect the concrete pouring. The sliding frame 3 slides on the laid track 2, reducing the reliance on manual labor and more effectively improving the construction efficiency of the hanging basket.
