Embodiment 1

[0028] refer to Figure 1-5 , an anti-tipping mechanism for a crane, comprising a crane outrigger, a base 1 connected to the bottom of the crane outrigger, a horizontal telescopic assembly hinged on the top of the crane outrigger through a hinge assembly, the base 1 is made of ferromagnetic material, and both sides of the base 1 are provided with There is a protective mechanism 2, and the protective mechanism 2 includes an I-shaped slide rail 3, and the first slider 6 is slidably connected to both sides of the I-shaped slide rail 3, and the two ends of the I-shaped slide rail 3 are fixed with limit blocks 4, and The bottom of the glyph-shaped slide rail 3 is connected to the ground, the first electric telescopic rod 7 is arranged between the limit block 4 and the first slider 6, and the top of the first slider 6 is fixedly connected with an "L"-shaped docking block 8, The end of the docking block 8 away from the I-shaped slide rail 3 is provided with an electromagnetic roller ...

Embodiment 2

[0037] Based on the previous embodiment, although the above-mentioned device can play the role of anti-tipping, the above-mentioned device can only be applied to the crane with the outrigger base 1 and the hydraulic support leg fixedly connected, but because the base 1 and the hydraulic support leg in the prior art Most of them are hinged, and the tipping process of the crane with hinged joints between the base 1 and the hydraulic support legs is as follows. Since the base 1 is hinged with the outriggers, after the whole crane tilts, one of the outriggers on one side of the crane tilts off the ground first, and the other outrigger The side still keeps in contact with the ground and the angle between the outrigger on the other side and the outrigger base 1 is relatively large, until the outrigger on the other side is tilted off the ground, and finally the phenomenon of rollover occurs; The supporting legs are hinged cranes to prevent tipping during the tilting process; at the sa...

Abstract

The invention relates to the technical field of cranes, in particular to an anti-overturning mechanism of a crane, which solves the problem in the prior art that when lifting heavy objects, the vehicle loses balance, the vehicle easily overturns, and accidents occur. An anti-overturning mechanism for a crane, comprising a crane outrigger, the bottom of the crane outrigger is hinged to a base through a hinge assembly, the top of the crane outrigger is hinged to a horizontal telescopic assembly through a hinge assembly, and the top of the base is provided with a hinge assembly Cooperating grooves; both sides of the base are provided with a protective mechanism, the protective mechanism includes an I-shaped slide rail, both sides of the I-shaped slide rail are slidably connected with a first slider, and the I-shaped slide rail Limiting blocks are fixed at both ends of the rail, and the bottom of the I-shaped slide rail is connected to the ground. The invention has a reasonable structure, is convenient to carry out limit support when rolling over, prolongs the reaction time, and thus avoids the occurrence of accidents.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane anti-tipping mechanism. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. A car crane is a kind of crane that is installed on an ordinary car chassis or a special car chassis. The driving cab and the lifting control room are set separately. The advantages of this kind of crane are good maneuverability and rapid transfer. When lifting, there is a rotating drum under the inside of the boom, and a steel wire rope is wound on it. The heavy arm is pulled out, and so on. [0003] However, during the lifting process of the truck-mounted crane, hydraulic cylinders are required to control the outriggers to support the vehicle to maintain the balance of the vehicle. The truck crane is also a typical dangerous mechanical device with high hidden dangers and high proba...
