Description

Technical Field

[0001] This utility model relates to the field of crane component transportation tools, and in particular to a gantry crane flexible leg joint transfer device. Background Technology

[0002] As is well known, during the transfer of gantry crane products, especially large gantry crane products, due to the large weight, high center of gravity, and special structure of gantry cranes, short-distance relocation at docks or between ships requires transportation vehicles with high safety, high efficiency, and ease of use. For the A-shaped upper joint of the flexible legs of gantry cranes, since there is no dedicated load-bearing transfer vehicle, for the sake of transfer safety, it can only be laid down, which increases the safety risks during the adjustment process, making the transportation less efficient and more inconvenient. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art and solve the existing technical problems, this utility model discloses a gantry crane flexible leg joint transfer device, which can improve the safety and convenience of load-bearing transportation by utilizing a low-cost and simple structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A gantry crane flexible leg joint transfer device includes two symmetrically spaced base plates. An adjusting assembly capable of adjusting the distance between the two base plates is connected between their corresponding inner end faces. Each base plate has an upward-facing upper support plate. The inner end of the upper support plate is rotatably connected to the inner end of the corresponding lower base plate via a first hinge shaft. A first telescopic cylinder is provided between the outer end of the upper support plate and the outer end of the corresponding base plate. Both ends of the first telescopic cylinder are rotatably connected to the upper support plate and the base plate respectively via second hinge shafts parallel to the first hinge shaft.

[0005] Furthermore, the adjusting component is configured as a double-ended screw with a hexagonal shoulder in the middle. The threads at both ends of the double-ended screw have opposite directions, and the inner end faces of the two base plates are respectively provided with threaded holes that are adapted to the screw ends.

[0006] Furthermore, the adjusting component is configured as a second telescopic cylinder.

[0007] Furthermore, lifting lugs are fixed on both sides of the outer end face of the upper support plate.

[0008] Furthermore, two first telescopic cylinders are connected to the outer ends of the base plate, and the telescopic rod is a hydraulic cylinder whose telescopic positioning is controlled by a hydraulic station.

[0009] Furthermore, the upper support plate includes a flat plate portion and vertical plate portions fixed at both ends of the flat plate portion, and a plurality of support rods are evenly spaced on the upper plate surface of the flat plate portion along the length direction of the upper support plate.

[0010] By adopting the technical solution described above, this utility model has the following beneficial effects: This utility model discloses a gantry crane flexible leg upper joint transfer device. For flexible leg A-shaped upper joints whose lower end faces are not on the same horizontal plane, a telescopic cylinder can be used to adjust the angle between the base plate and the upper support plate. This allows the upper support plate to better fit the corresponding side bottom surface supporting the A-shaped upper joint, ensuring transportation safety without having to lay the upper joint down. Furthermore, by using an adjusting component to adjust the distance between the two base plates, the transfer device can adapt to carrying upper joints of different specifications, further improving support stability. In summary, this utility model has a simple structure, low cost, is easy to use, and has strong adaptability. It can easily, conveniently, and safely relocate flexible leg upper joints for gantry cranes. Multiple use tests have fully verified the feasibility and economic value of this device.

[0013] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0014] Combined with appendix Figure 1The aforementioned gantry crane flexible leg upper joint transfer device includes two symmetrically spaced base plates 1. The two base plates 1 have flush surfaces serving as a base, and an adjusting component 2 is connected between the corresponding inner end faces of the two base plates 1 to adjust the distance between them. By adjusting the spacing between the two base plates 1, it can accommodate upper joints of different span specifications. As needed, the adjusting component 2 can be a double-ended screw with a hexagonal shoulder in the middle. The threads at both ends of the double-ended screw have opposite directions of rotation, and the inner end faces of the two base plates 1 are respectively provided with threaded holes corresponding to the two ends of the double-ended screw. When the hexagonal shoulder is turned with a tool to drive the double-ended screw to rotate, the two base plates 1 can move closer or further apart simultaneously due to the opposite directions of rotation of the threads at both ends. Alternatively, the adjusting component 2 can also be a second telescopic cylinder, which can be an electric cylinder or a hydraulic cylinder to automatically control and adjust the distance between the two base plates 1. Each base plate 1 is topped with an upward-facing upper support plate 3. Two upper support plates 3 form an angle with the bottom surface of the corresponding leg joint for support. Specifically, the upper support plate 3 includes a flat plate portion 301 and vertical plates fixed to both ends of the flat plate portion 301. Multiple support rods 302 are evenly spaced along the length of the upper support plate 3 on the upper surface of the flat plate portion 301, ensuring sufficient connection and support strength while providing a certain anti-slip effect. Furthermore, lifting lugs 7 are fixed on both sides of the outer end face of the upper support plate 3 for easy hoisting and movement. The inner end of the upper support plate 3 is rotatably connected to the inner end of the corresponding base plate 1 below via a first hinge shaft 5. Specifically, hinges are installed on the upper support plate 3 and the base plate 1. The hinge seat is hinged via a first hinge shaft 5, which is axially parallel to the surfaces of the upper support plate 3 and the base plate 1, allowing the upper support plate 3 to rotate relative to the base plate 1 to adjust its angle. A first telescopic cylinder 4 is provided between the outer end of the upper support plate 3 and the corresponding outer end of the base plate 1. Both ends of the first telescopic cylinder 4 are rotatably connected to the upper support plate 3 and the base plate 1 respectively via a second hinge shaft 6 parallel to the first hinge shaft 5. By controlling the extension and retraction of the second telescopic cylinder, support force and rotational power are provided to the upper support plate 3. If necessary, two first telescopic cylinders 4 are connected to both sides of the outer end of the upper plate surface of the base plate 1, and the telescopic rod is set as a hydraulic cylinder controlled by a hydraulic station 8 for extension and positioning, making the hydraulic system control more stable.

[0015] The gantry crane flexible leg joint transfer device described in this utility model is as follows: Figure 2 As shown, it is necessary to first adjust the distance between the two base plates 1 using the adjusting component 2 according to the specifications and shape of the flexible leg upper connector to be supported, and then adjust the angle of the supporting surface of the upper support plate 3 using the first telescopic cylinder 4. Then, the flexible leg upper connector can be directly hoisted and placed on the transfer device. The transfer device can be placed on a hydraulic flatbed truck in advance. With manual operation of the hydraulic flatbed truck, it can be transferred to the target site in a very convenient and safe manner.
