Arm lever storing and stacking device for crawling crane

Abstract

The invention relates to an arm lever storing and stacking device for a crawling crane. The arm lever storing and stacking device comprises a lower support, an upper support, a base, a connecting rodI, a connecting rod II and a fixed ring clamp. An arc-shaped groove is formed in the upper part of the lower support, a lower support screw is arranged on the lower part of the lower support, and an outer thread is arranged on the outer part of the lower support; an arc-shaped groove is formed in the upper part of the upper support, a lower threaded hole is formed in the lower part of the upper support, an inner thread is arranged in the lower threaded hole, the inner thread of the lower threaded hole is matched with the outer thread of the lower support screw, a side threaded hole is formed in the side face of the upper support, an inner thread is arranged in the side threaded hole, and the axis of the side threaded hole is parallel to the axis of the arc-shaped groove in the upper part of the upper support; a base threaded hole is formed in the base, an inner thread is arranged on the base threaded hole, and the inner thread of the base threaded hole is matched with the outer threadof the lower support screw. The lower support and the base are combined to form a ground arm lever storing device and the upper support and the lower support are combined to form an upper layer arm level stacking device.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a device and method for storing and stacking a crawler crane arm. Background technique [0002] The crawler crane is a kind of crane that is widely used at present. After it is hoisted and used, it needs to be disassembled into parts for transfer and storage according to the assembly structure. Among them, the relatively large crawler cranes generally require more than 30 17.5-meter flatbed trucks for transportation, and the requirements for the parking area and flatness of the crawler crane parts are relatively high. Among its components, the arm is the largest in number and occupies the largest area (the size is generally 12000mm*3000mm). Generally, the boom used by crawler cranes is similar to that used by tower cranes. The difference is that the booms of tower cranes are generally triangular prism structures, while the booms of crawler cranes are generally square prism stru...
