Description

Technical Field

[0001] This utility model relates to the field of flexible outriggers for double-girder gantry cranes, specifically the flexible outriggers of double-girder gantry cranes. Background Technology

[0002] Large double-girder gantry cranes are generally used in shipbuilding companies. They have a large lifting capacity, some reaching hundreds of tons. Gantry cranes with large spans have a self-weight of over a thousand tons. The added weight puts a lot of pressure on the outriggers. If both outriggers are rigidly connected, the stress on the outriggers cannot be released after lifting heavy objects. In addition, the internal stress of the main beam and outriggers changes frequently due to gravity caused by frequent lifting and unloading. This can cause irreversible plastic deformation or hidden safety hazards in the weaker parts of the steel structure.

[0003] The flexible outriggers of existing double-girder gantry cranes are not easy to adjust in terms of their support position, requiring constant adjustments, which is inconvenient to use. Furthermore, the flexible outriggers of existing double-girder gantry cranes are not easy to adjust in terms of their support length, resulting in poor practicality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides flexible outriggers for a double-girder gantry crane, solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flexible outrigger for a double-girder gantry crane, comprising a movable frame, a gantry support fixedly mounted on the top of the movable frame, a crane mounted on the top of the gantry support, a movable wheel fixedly mounted on one side of the bottom of the movable frame, a lead screw rotatably connected to one side of the movable frame, a servo motor fixedly mounted on one side of the top of the movable frame, the output end of the servo motor fixedly mounted on one end of the lead screw, a sliding seat slidably connected to the outside of the lead screw, the bottom of the sliding seat slidably connected to the top of the movable frame, a support fixedly mounted on one end of the sliding seat, a rotating shaft rotatably connected inside the support, a rotating frame fixedly mounted on the outside of the rotating shaft, and a driven gear fixedly mounted on one end of the rotating shaft.

[0008] Optionally, a motor mount is fixedly installed on the top of the sliding seat, and a motor is fixedly installed on one side of the motor mount.

[0009] Optionally, a drive gear is fixedly mounted on the output end of the motor, and the outer side of the drive gear meshes with the outer side of the driven gear.

[0010] Optionally, one end of the rotating frame is provided with a telescopic groove, and a telescopic frame is slidably connected inside the telescopic groove.

[0011] Optionally, a connecting seat is fixedly installed at one end of the telescopic frame, and a connecting frame is fixedly installed at one end of the connecting seat.

[0012] Optionally, a first electric telescopic rod is fixedly installed inside the connecting frame, and a telescopic support seat is fixedly installed at the extended end of the first electric telescopic rod.

[0013] Optionally, a mounting base is fixedly installed on one side of the rotating frame, and a second electric telescopic rod is fixedly installed inside the mounting base.

[0014] Optionally, a pusher seat is fixedly installed at the extended end of the second electric telescopic rod, and a side of the telescopic frame is fixedly installed on one side of the pusher seat.

[0015] This utility model provides flexible outriggers for a double-girder gantry crane, which have the following advantages:

[0016] 1. The flexible outriggers of this double-girder gantry crane, through the setting of the rotating frame, enable easy adjustment of their support position without the need for constant adjustments. Through the coordinated arrangement of the moving frame, gantry support, crane, moving wheels, lead screw, servo motor, sliding seat, support, rotating shaft, rotating frame, driven gear, motor base, motor, and drive gear, when the position of the rotating frame needs adjustment, the servo motor is activated. The output of the servo motor drives the lead screw to rotate, causing the lead screw to rotate inside the moving frame. The lead screw then drives the sliding seat to slide on top of the moving frame, which in turn moves the support, adjusting it to the appropriate position. Activating the motor then drives the drive gear to rotate, which in turn drives the driven gear to rotate, causing the rotating shaft to rotate inside the support. The rotating shaft then drives the rotating frame to rotate inside the support, further adjusting the rotating frame to the appropriate position. This achieves good adjustment effect and convenient use.

[0017] 2. The flexible outriggers of this double-girder gantry crane, through the installation of telescopic frames, enable easy adjustment of their support length. Through the coordinated arrangement of telescopic grooves, telescopic frames, connecting seats, connecting brackets, a first electric telescopic rod, a telescopic support seat, a second electric telescopic rod, and a pusher seat, during use, when the support length needs adjustment, the second electric telescopic rod is opened. The extended end of the second electric telescopic rod drives the pusher seat to move, which in turn drives the telescopic frame to move, allowing the telescopic frame to slide within the telescopic groove. The telescopic frame, through the connecting seat, drives the connecting bracket to move, thus adjusting the connecting bracket to the appropriate position. When support is needed, the first electric telescopic rod is opened. The extended end of the first electric telescopic rod drives the telescopic support seat downwards, thereby supporting the entire device. This achieves high adjustment efficiency and strong practicality. Attached Figure Description
