AI Technical Summary
In bridge construction, tower cranes are difficult to adjust due to the connection method between the attachment frame and the bridge tower, which makes the verticality of the tower crane unable to meet the specification requirements. Especially when the bridge tower is offset by a large distance, the existing adjustment methods are complex and inconvenient.
A crane attachment device is designed, including a fixed base, a movable attachment base and a driving mechanism. The left and right movement of the attachment base is achieved through guide rails and rolling members. The driving mechanism uses a telescopic cylinder to drive the attachment base to adjust, simplifying the adjustment operation.
The verticality adjustment of the tower crane is realized, ensuring that the verticality of the tower crane meets the requirements, simplifies adjustment operations, and improves the convenience and reliability of construction.

[0035] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0036] For tower cranes attached to bridge towers, as the bridge towers shift, the tower cranes will also shift together. In order to ensure that the verticality of the tower crane meets the requirements, the base must be moved in the opposite direction synchronously to ensure that the verticality meets the requirements. The existing attachment base is connected to the building by bolts or welding, and the base is immovable. In the case of necessary adjustment, the project site needs to pre-embed new attachment bases in advance, and then adjust the attachment support rods one by one to the new position, which is very difficult to operate. If other bases are not pre-embedded in advance, there will be no way to adjust. In addition, in the case of some existing bases that are immovable, due to the large offset of the bridge tower, the verticality of the tower crane will not meet the requirements.
[0037] In view of this, if Figure 1 As shown, the present application provides a crane attachment device, which includes a fixed base 2, an attachment base 1 and a driving mechanism 3. The fixed base 2 is used to be fixedly connected to the attached object, the attachment base 1 is movably arranged on the fixed base 2 and can move in the left and right directions, the driving mechanism 3 is arranged on the fixed base 2 and connected to the attachment base 1, and the driving mechanism 3 is used to drive the attachment base 1 to move.
[0038] It can be seen that since the attachment base 1 is movably arranged on the fixed base 2 and can move in the left and right directions, after the crane attachment device is installed, the crane attachment device can adjust the relative fixed position of the attachment base 1 and the attached object according to the offset of the bridge tower, so as to move the attachment frame as a whole to one side, realize the vertical adjustment of the tower crane, and ensure that the verticality of the tower crane meets the requirements. In addition, the crane attachment device is also provided with a driving mechanism 3, which can drive the attachment base to move, making the adjustment operation simpler and more convenient.
[0039] Those skilled in the art can understand that the structure of the attachment base 1 can be varied, for example, including a connecting ear plate with multiple connecting ear holes or a connecting plate with a pivot shaft welded thereon, etc.; the number of attachment bases 1 can be 2, 3 or more, etc.; the number of drive mechanisms 3 can be set one-to-one with the number of attachment bases 1, or can be less than the number of attachment bases 1, in which case one drive mechanism 3 can simultaneously drive multiple attachment bases 1 to move.
[0040] In addition, the movable connection structure of the fixed base 2 and the attachment base 1 can also be various, for example, the fixed base includes a guide rail portion extending in the left-right direction, and the attachment base 1 is inserted on the guide rail portion or embedded in the guide rail portion and can move in the left-right direction. Other structural forms that can realize the movable setting of the attachment base 1 on the fixed base 2 should also fall within the protection scope of this application. The power element of the driving mechanism 3 can be a telescopic cylinder or an electric telescopic arm, etc., and this application is not limited thereto.
