A foot plate and a crane for installing the foot plate

Abstract

The invention discloses a foot plate and a crane installed with the foot plate, which belong to the technical field of crane equipment. The foot plate 2 includes a guide groove, a support seat for installing the guide groove, and a support seat arranged on the top of the support seat for installing an oil cylinder ball. The ball socket of the head; the limit groove is opened on the support seat, and the ball socket is embedded in the limit groove. The ball socket and the support seat adopt interference fit; the guide groove adopts a non-linear structure, and the guide groove is provided with a hook limit beam, For the working hole position and the hanging hole position, when the cylinder head of the vertical oil cylinder is located in the ball socket, the fastening pin shaft is installed in the working hole position to make the second foot plate in the working state; when the cylinder ball head of the vertical oil cylinder is detached from the ball When nesting, fastening pins are installed in the hanging holes so that the second leg plate is in a non-working state. The foot plate provided by the present invention adopts an integral molding structure to manufacture the support seat of the foot plate, and the material specific gravity of the support seat is lighter than the existing steel structure, which can greatly reduce the weight of the entire foot plate structure compared with the steel welded structure.

Description

technical field [0001] The invention relates to a foot plate and a crane equipped with the foot plate, belonging to the technical field of crane equipment. Background technique [0002] The foot plate in the crane is a similar plate structure, which is used to support the crane in the lifting operation and transmit the force to the support surface, so as to play the role of bearing capacity and stable operation equipment. Generally, a crane has four foot plates, and the four foot plates are in contact with the support surface during the lifting operation to form a four-point support. [0003] The outrigger plate in the crane is generally installed at the end of the vertical cylinder of the outrigger, and moves with the movement of the vehicle and the vertical cylinder. There are mainly two types of foot plates used in cranes, one is the gland type; the other is the push-pull type, such as figure 1 As shown, the supporting leg plate one 1 is connected with the vertical oil ...

Problems solved by technology

[0007] 2) The existing foot plate is welded with a steel structure, and the weight is relatively heavy. It is difficult to adjust the two positions by manpower. Moreover, under the requirements of the lightweight structure of the whole machine, its overall weight and structural form are the key points that need to be improved. point
