Abstract

The invention belongs to the field of construction machinery, and specifically relates to an area-variable foot plate, which includes a support, a first pin structure, and a second pin structure; the support is provided with a support plate and a support block, and the first A pin shaft structure is arranged on the support plate to limit the position of the support plate in different states; the second pin structure is installed on the support to limit the position of the hydraulic cylinder; the support plate A first pin hole and a second pin hole are provided; the first pin hole and the second pin hole are used to install the first pin structure, and the first pin hole corresponds to the second state of the foot plate The position of the first pin shaft structure at the same time, the second pin shaft hole corresponds to the position of the first pin shaft structure at the first state of the foot plate. The foot plate structure can realize the change of the supporting area of ​​the foot plate, so as to solve the contradiction between the improvement of the bearing capacity and the storage in the limited space in the existing solutions.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to an area-variable support foot plate. Background technique [0002] During the hoisting operation of the mobile crane, the whole vehicle needs to be supported by movable outriggers, and the weight of the whole vehicle and the weight of the hoisted objects are finally transmitted to the ground through the outrigger plate. For safety reasons, to prevent the ground from sinking under force, the crane must meet a certain grounding specific pressure requirement, which requires that the supporting surface of the foot plate must be as large as possible; the foot plate needs to be stored in the vehicle in the driving state to ensure that the whole vehicle is not too wide. Due to the limited storage space, the supporting surface of the foot plate is required to be as small as possible. This has just formed a pair of technical contradictions: the area of ​​the foot plate ne...
