Problems solved by technology

[0002] When the front stacker is lifting the container, the gravity of the container will give the whole vehicle a forward tilting moment with the axle center of the front axle as the zero point. In order to prevent the overturning of the whole vehicle caused by such a large moment, certain preventive measures must be taken. Therefore, most of the existing container reach stackers have anti-overturning mechanisms, and most of the force transmission parts of the existing anti-overturning mechanisms have vulnerable parts, and the structural design of the anti-overturning mechanisms is complicated, and the reliability of anti-overturning is low.

Embodiment 1

[0037] like figure 1 As shown in the sectional view of an embodiment of the anti-overturning device of the container reach stacker of the present invention, the anti-overturning device of the container reach stacker of the present invention includes: a first bracket 13 arranged between the vehicle frame and the rear axle of the lifter And the second bracket 14, the sensor 10, the controller, the vehicle frame and the rear axle are hinged to each other through the first bracket and the second bracket, and the second bracket includes a moving pair up and down. When dangerous, the rear part of the frame will be upturned, the rear axle will rotate around the hinge point of the first bracket under the action of its own weight, relative movement will occur between the up and down moving sub-components, and the sensor will detect the up and down movement The secondary movement signal is sent to the controller, and the controller controls the boom of the hoist to stop extending and li...

Embodiment 2

[0052] like Image 6 As shown, the diameter of the middle part of the third pin shaft 7 in this embodiment is larger than the diameter of both ends; the through holes 30a and 30b on the rear axle box body 3 are installed with a stop block 7c used to stop the middle part of the third pin shaft , the stop block 7c can be fixed at any position in the through holes 30a, 30b, so as to reduce the opening width of the through holes 30a, 30b, so that the opening width of the through holes 30a, 30b is smaller than the middle diameter of the third pin shaft, so as to prevent the opening width of the third pin shaft. Tripod shaft 7 escapes from through hole 20 .

[0053] Other structures of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention discloses an overturn preventing device of a reach stacker, which is characterized in that the device comprises a first bracket (13) and a second bracket (14) which are arranged between a frame and a rear axle of the reach stacker, a sensor (10) and a controller; the frame and the rear axle are mutually hinged through the first bracket and the second bracket; the second bracket comprises a longitudinal moving pair; when the reach stacker is in danger of overturning, elements of the longitudinal moving pair relatively move; the sensor detects movement signals of the longitudinal moving pair and sends the movement signals to the controller; and the controller controls an arm support of the reach stacker to stop extending and raising. The device has the advantages of simple structure design and low cost.

Description

technical field [0001] The invention relates to an anti-overturning device, in particular to an anti-overturning device for a front stacker of a container. Background technique [0002] When the front stacker is lifting the container, the gravity of the container will give the whole vehicle a forward tilting moment with the axle center of the front axle as the zero point. In order to prevent the overturning of the whole vehicle caused by such a large moment, certain preventive measures must be taken. Therefore, most of the existing container reach stackers have anti-overturning mechanisms, and most of the existing anti-overturning mechanism force transmission parts have vulnerable parts, and the anti-overturning mechanism has complex structural design, and the reliability of anti-overturning is low. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problems in the prior art and provide a container reach stacker anti-o...
