Description

Technical Field

[0001] This utility model belongs to the field of crane equipment technology, and in particular relates to a support device for a mobile tower crane. Background Technology

[0002] Tower cranes, also known as tower hoists, are rotating cranes with their jibs mounted on a tall tower. They offer a large working space and are primarily used for the vertical and horizontal transport of materials and the installation of building components in construction. During operation, the crane requires support from outriggers, and additional support blocks are placed at the lower ends of the outriggers. Since the ground is often uneven, support blocks of varying heights are needed. Therefore, a movable tower crane support device is proposed, capable of adjusting the height of the support blocks to facilitate crane support. Utility Model Content

Multiple retractable hydraulic telescopic components are installed on the base frame assembly and arranged symmetrically along the center of the base frame assembly. The retractable hydraulic telescopic components are connected to the control valve group of the vehicle-mounted hydraulic pump station through hydraulic pipelines. Support components are installed on the retractable hydraulic telescopic components for supporting the retractable hydraulic telescopic components.

[0005] The retractable hydraulic telescopic component has a support leg installed at its lower end, and the support component is located at the lower end of the support leg.

[0006] The support assembly includes a support plate located at the lower end of the support leg. One side wall of the support plate has a slot, and the other side wall of the support plate has a protrusion.

[0007] The support assembly further includes a connecting block one and a connecting block two. The side wall of the connecting block one is provided with a protrusion two, and the side wall of the connecting block two is provided with a slot two. The protrusion two can be movably engaged in the slot one and the slot two, and the protrusion one can be movably engaged in the slot two.

[0008] Among them, the first slot, the first protrusion, the second slot, and the second protrusion are all inclined.

[0009] The support plate is provided with a fixing hole one, the connecting block one is provided with a fixing hole two, and the connecting block two is provided with a fixing hole three. When the connecting block one and the connecting block two are located at the lower end of the support plate, the fixing hole one is connected to the fixing hole two and the fixing hole three respectively.

[0010] The support plate has a baffle on its side wall. When connecting block 1 and connecting block 2 are installed on the support plate, the baffle is set to fit against connecting block 1 and connecting block 2 to fix connecting block 1 and connecting block 2.

[0011] With the above structure, the beneficial effects of this utility model are as follows: When connecting block one and connecting block two are not needed, the protrusion two on connecting block one is inserted into the slot one on the support plate, and the slot two on connecting block two is connected to the protrusion two, which is convenient for installation and storage; when connecting block one and connecting block two are needed for auxiliary support, connecting block one and connecting block two after connection are placed at the lower end of the support plate, and fixed by external fixing rods passing through fixing hole one, fixing hole two and fixing hole one fixing hole three respectively, thereby increasing the height of the support plate and facilitating the support of the outriggers.
