Description

Technical Field

[0001] The utility model relates to the technical field of lifting machinery, in particular to a multifunctional bracket structure for a crane which can carry a pad and a spare tire at the same time. Background Art

[0002] When the crane is in operation, its main structure needs to withstand a large force. To ensure its stability during operation and to ensure this stable state, it is necessary to lay a flat foot pad under the outrigger to increase the contact area between the crane and the ground. The foot pad is heavy and has a large area, so the transportation of the foot pad requires a separate transport vehicle, which increases transportation costs, increases the preparation time for the crane, and affects operating efficiency. In addition, in order to prevent the tires from being damaged during the transfer transportation process, thereby affecting the transfer transportation efficiency, the crane generally carries a spare tire with it. If the tire is damaged during the transfer transportation process, it can be replaced in time without affecting work efficiency.

[0003] There are two forms of transportation for the crane's support foot pads: one form is to place the support foot pads on a separate transport vehicle, and as the crane moves, the transport vehicle that transports the support foot pads moves with it. This mode of transportation can meet the needs of transporting and transferring the support foot pads, but it requires a separate transport vehicle, which increases the cost of transportation and transfer and reduces work efficiency. Another form of transportation is to design a fixed bracket at the tail end of the crane, place the support foot pads on the fixed bracket, and limit the support foot pads in all directions through the fixed bracket structure to ensure that the support foot pads are stable, safe and reliable during transportation. Spare tires are generally fixed to the tail of the crane through a special spare tire bracket and transported with the crane body. However, due to the limited space at the rear of the crane, when the pad bracket is installed at the tail of the crane for pad transportation, the installation space of the spare tire bracket is often occupied. Therefore, the pad and spare tire can only be selected during transportation, which cannot meet actual needs.

[0004] In response to the needs of flexible transfer and convenient transportation put forward by the existing crane market, the utility model combines the existing technology and structural design, and proposes a multifunctional bracket structure for a crane that can carry a pad and a spare tire at the same time while ensuring the high reliability of the lifting machinery and the safety of transfer and transportation.

The installation method of the support foot pad and the spare tire is convenient and quick, which improves the working efficiency of the crane. BRIEF DESCRIPTION OF THE DRAWINGS
