Abstract
Description
Technical Field
[0001] This application relates to the field of hoisting equipment technology, and in particular to a hoisting device for the construction of steel-concrete composite beams. Background Technology
[0002] A related technology (publication number: CN216471941U) discloses a hoisting device for the construction of steel-concrete composite beams for viaducts. After the hoisting device is moved to a designated location, the motor is activated, which drives a circular rod to rotate. Then, through the meshing of the bevel gear set, the rotating rod rotates, thereby driving a threaded rod to rotate. At this point, the moving block can slide within the moving groove, ultimately adjusting the positions of the wire rope, the first fixed frame, the second fixed frame, and the third fixed frame, making it suitable for use in confined terrain.
[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:
[0004] The hoisting device used for the construction of the steel-concrete composite beam of the viaduct can adjust the positions of the wire ropes, the first fixed frame, the second fixed frame, and the third fixed frame. However, because the first fixed frame, the second fixed frame, and the third fixed frame cannot be folded, and the fixing plate itself cannot be used for ropes, it still occupies a considerable amount of space.
[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0017] The present technical solution provides a hoisting device for the construction of steel-concrete composite beams, which can achieve the following technical effects:
[0018] This disclosure provides a hoisting device for constructing steel-concrete composite beams, comprising a chassis, a second rectangular tube, a first hydraulic cylinder, a support, a swing arm, a lifting component, and a first caster. The chassis includes two first rectangular tubes, which are parallel to each other and axially symmetrically distributed, respectively supporting the installation of slidable second rectangular tubes and the first caster. The second rectangular tubes are slidably inserted into the interiors of the two first rectangular tubes and can slide relative to them. The first hydraulic cylinders are installed between the two second rectangular tubes and the two first rectangular tubes along the sliding direction of the two second rectangular tubes relative to the two first rectangular tubes, respectively, and are used to provide driving force. The support is installed on the top surface of the chassis and supports the rotatable swing arm.

The chassis 10 includes two first rectangular tubes 11, which are parallel to each other and axially symmetrically distributed, respectively supporting the slidable second rectangular tube 20 and the first caster 80. The second rectangular tubes 20 are slidably inserted into the interiors of the two first rectangular tubes 11 and can slide relative to each of the two first rectangular tubes 11. The first hydraulic cylinders 30 are installed between the two second rectangular tubes 20 and the two first rectangular tubes 11 along the sliding direction of the two second rectangular tubes 20 relative to the two first rectangular tubes 11, respectively, and are used to provide driving force. The bracket 40 is installed on the top surface of the chassis 10 and is used to support the rotatable swivel arm 50. One end of the swivel arm 50 is rotatably mounted on the top of the bracket 40 and can rotate relative to the bracket 40. A lifting component 60 is mounted on the boom 50 for lifting heavy objects. A second hydraulic cylinder 70 is rotatably mounted between the bracket 40 and the boom 50, and can rotate relative to both the bracket 40 and the boom 50 to provide driving force.

Driven by the two first hydraulic cylinders 30, the two second rectangular tubes 20 slide relative to the two first rectangular tubes 11, and driven by the second hydraulic cylinder 70, the boom 50 rotates relative to the bracket 40.
[0038] This disclosure provides a hoisting device for constructing steel-concrete composite beams. Controlling two first hydraulic cylinders 30 causes two second rectangular tubes 20 to slide relative to two first rectangular tubes 11, allowing the second rectangular tubes 20 to extend or retract from the interior of the first rectangular tubes 11. Controlling a second hydraulic cylinder 70 causes a rotating arm 50 to rotate relative to a support 40, allowing the arm 50 to fold or unfold relative to the support 40. When the two second rectangular tubes 20 are extended and the arm 50 is unfolded, stable support is formed, facilitating hoisting. When the two second rectangular tubes 20 are retracted and the arm 50 is folded, the space occupied by the device is reduced. This facilitates both moving and transporting the entire device.
