A multifunctional crane

Abstract

The invention discloses a multifunctional crane, which belongs to the field of cranes, and comprises a first clamping arm, which is rotatably connected to a fixed seat, and a third clamping arm is articulated between the first clamping arm and the fixed seat. A hydraulic cylinder, one end of the first clamping arm is rotatably connected to the second clamping arm, a fourth hydraulic cylinder is hinged between the first clamping arm and the second clamping arm, and one end of the second clamping arm is provided with The first clamping rod and the second clamping rod, the clamping spring is fixedly connected between the first clamping rod and the second clamping rod, one side of the first clamping rod is fixedly connected to the connecting seat, the An elastic rope is arranged between the connecting seat and the fixing seat. The present invention rotates the second clamping rod through the elastic rope, so that the device can clamp larger objects through the cooperation of the second clamping rod with the first clamping arm and the second clamping arm, and can also clamp the larger object through the first clamping arm. The holding rod and the second clamping rod cooperate to clamp smaller objects, which is flexible in use, does not need to be disassembled, and saves time in use.

Description

technical field [0001] The invention belongs to the field of multifunctional cranes, and in particular relates to a multifunctional crane. Background technique [0002] Cranes mainly include hoisting mechanism, running mechanism, luffing mechanism and slewing mechanism. The hoisting mechanism is the basic working mechanism of the crane, mostly composed of a suspension system and a winch, and also lifts heavy objects through a hydraulic system. The operating mechanism is used to move heavy objects vertically and horizontally or adjust the working position of the crane, and is generally composed of a motor, a reducer, a brake and wheels. The luffing mechanism is only equipped on the jib type crane. When the jib is raised, the range decreases, and when it is lowered, the range increases. There are two types: balanced luffing and unbalanced luffing. The slewing mechanism is used to turn the arm frame, and it is composed of a driving device and a slewing support device. [000...

Problems solved by technology

[0003] Now when using a crane to clamp objects, when objects of different volumes need to be clamped, grippers of different sizes need to be disassembled and replaced to meet the needs of clamping and moving objects of different sizes. The operation is complicated and the grippers need to be replaced. Waste a lot of time and seriously affect the work progress
