Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a crane used for lifting a bucket screen. Background Art

[0002] Dou screen usually refers to a large spliced ​​display screen combination, which is composed of multiple screens spliced ​​together to form a large display system capable of displaying complex content. These screens can be liquid crystal displays (LCD), organic light-emitting diode displays (OLED) or screens using other display technologies.

[0003] The internal support frame of the bucket screen is assembled by two U-shaped brackets, each of which includes a main frame. A rotatable side frame is hinged at both ends of each main frame. During installation, the two relatively placed brackets are lifted and the side frames are rotated, and then spliced ​​to form a quadrilateral support frame. Therefore, during installation, in addition to normal lifting, the two side frames need to be opened. The existing installation operation is to install different hoists at different positions, perform linear motion, and then complete the state change of the side frame (that is, from a parallel state to a vertical state with the main frame). This method requires at least four hoists in different directions to complete (that is, a bridge-type lifting device is set up on the outside of the four surfaces of the entire support frame). This results in the need to install and disassemble each lifting device before and after installation. The process is cumbersome and the accuracy of docking cannot be accurately controlled. Multiple measurements are required, which reduces the installation efficiency of the bucket screen. Utility Model Content

[0004] In order to solve the above problems, an embodiment of the utility model provides a bucket screen lifting crane that only needs two bridge-type lifting devices to complete the bucket screen installation operation.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a bucket screen lifting crane, including a walking beam, a lifting module is arranged in the middle of the walking beam, and walking modules are arranged at both ends of the walking beam. The lifting module includes a first hoisting device connected to the fixed part of the bucket screen frame, and a second hoisting device connected to the rotating part of the bucket screen frame. The walking module includes a trolley, a track clamp is arranged on one side of the trolley, and a driving source is arranged on the other side. The upper part of the trolley is provided with an adjustment seat connected to the walking beam.

[0006] As a further improvement of the above technical solution:

[0007] Two groups of walking modules are respectively arranged at both ends of the walking beam, and the two groups of walking modules are symmetrically distributed with the center line of the walking beam as the axis.

[0008] The adjusting seat comprises a connecting shaft, both ends of the connecting shaft are provided with mounting plates connected with the trolley, and the middle part of the connecting shaft is slidably provided with a sliding seat connected with the walking beam.

[0009] The sliding seat comprises a base body, the upper part of which is provided with a flange plate for connecting a walking beam, the lower part of which is provided with a joint bearing sleeved on a connecting shaft, and a sliding sleeve is provided between the joint bearing and the connecting shaft.

[0010] The second sling is located outside the first sling, and an adjusting device for adjusting the position of the second sling is provided on the walking beam.

[0011] The adjusting device comprises a guide rail arranged at the lower part of the walking beam, a mounting frame for mounting the second sling is arranged at the lower part of the guide rail, and a driving motor is arranged at the connection between the mounting frame and the guide rail.

[0012] The beneficial effects of the embodiments of the utility model are as follows: the bucket screen lifting crane comprises a walking beam, a lifting module is arranged in the middle of the walking beam, and walking modules are arranged at both ends of the walking beam, and the lifting module comprises a first sling connected to the fixed part of the bucket screen frame, and a second sling connected to the rotating part of the bucket screen frame. The walking module can drive the walking beam to move, thereby changing the position of the bucket screen frame. When it moves to the set position, the second sling drives the rotating part of the bucket screen frame to rotate outward. Through the design of the walking module, the first sling and the second sling, two bridge cranes can be used to complete the shape change and splicing operation of the bucket screen frame. Compared with the conventional method of using multiple bridge cranes in combination, it can reduce the workload of erecting and disassembling the lifting equipment, save operating costs and improve operating efficiency.
