Dismantling and transporting device of large pin shaft of crawler crane

Abstract

The invention provides a large link-pin assembling/disassembling/conveying device for crawler cranes, and the device provided by the invention comprises a support, a clamping plate, baffle plates, blocking pins and a pulling pin, wherein the support mainly comprises an arc-shaped supporting plate and two channel rails; one side of the arc-shaped supporting plate is provided with a U-shaped baffle plate, the other side of the arc-shaped supporting plate is provided with a hollow ring baffle plate, and a link pin can pass through the middle part of the ring baffle plate; the two channeled rails are provided with four hoisting points which are adjusted to proper positions on a crane main body, and one end of the support can be fixed onto the crane main body by use of bolts; the clamping plate close to the U-shaped baffle plate is fixed on the support; the baffle plates are fixed in the support by virtue of the blocking pins; and the pulling pin is fixed on the two channeled rails. The large link-pin assembling/disassembling/conveying device provided by the invention has the advantages that the device can be used for carrying out fractional assembling/disassembling on link pins by using a pulling-pin cylinder; the device is simple in structure and convenient to operate; and when the device is used for conveying, the firm fastening of link pins can be realized, so that the device is safe and reliable, and the labor intensity of operators and the operating costs can be lowered, therefore, the device has higher application value.

Description

technical field [0001] The invention relates to the technical field of crawler cranes, in particular to a large pin shaft disassembly and transportation device for crawler cranes. Background technique [0002] At present, many large structural parts of large crawler cranes produced at home and abroad are connected by pin shafts, and the pin shafts are transported with the main body. However, when the weight of the structural parts of the super-large tonnage crawler crane is relatively large, the problem of overweight often occurs when the pin shaft is transported with the main body. [0003] If the pin shaft is disassembled for transportation, manual disassembly or hydraulic disassembly is required. When manual disassembly is used, due to the large pin shaft, manual disassembly is also difficult, which undoubtedly increases the labor intensity of the operator; while hydraulic disassembly requires external power and hydraulic components, the operating cost is relatively high...
