Abstract
The invention discloses a device for preventing collision between crossed cantilever cranes. The device is characterized by comprising limit switches positioned on stand columns of cantilever cranes, limit collision strikers and control boxes, wherein the control boxes are connected with the limit switches. The device is simple in structure, and convenient to mount, and can ensure automatic collision prevention of cantilevers in a working crossed area and the safety production.
Description
Technical field
The present invention relates to a kind of cantilever crane, especially a kind of cantilever crane intersection anticollision device.
Background technology
The column cantilever crane belongs to light hoisting gear, require little at scope of work, in the little situation of hoisting capacity, this hoisting crane is more and more in application, thereby, such problem has appearred, the phenomenon that in the radius of operating area, has two forked workings, the technological requirement that anticollision between cantilever so just occurred, conventional all is to adopt manual control, so very dangerous.
Summary of the invention
The present invention seeks to: the cantilever crane intersection anticollision device that the collision problem in the working process between a kind of solution cantilever simple in structure, easy to use is provided.
Technical scheme of the present invention is: a kind of cantilever crane intersection anticollision device is characterized in that comprise the limit switch that is positioned on the cantilever crane column, spacing chi and the control box of hitting, described control box links to each other with limit switch.
Further, described limit switch is the cross limit switch.
Further, the described spacing chi that hits is 3, lays respectively at the left-handed terminal point of cantilever crane cantilever, dextrorotation terminal point and intersection region point.
Further, described control box is the PLC controller.
A kind of cantilever crane intersection avoiding collision is characterized in that, may further comprise the steps:
(1) determines left-handed terminal point A1, A3 and dextrorotation terminal point B1, the B3 of described cantilever A, B according to the anglec of rotation of cantilever A, the B of cantilever crane; There is the surface area R that intersects in the range of movement of the cantilever that (2) calculates every cantilever crane according to position and the anglec of rotation of every cantilever crane, and intersection region point A2 and the B2 of definite cantilever A, B;
(3) in the time of in cantilever enters the Zone R territory, the signal of intersection region point A2 and B2 is 0; When cantilever is in Zone R when overseas, the signal of intersection region point A2 and B2 is 1; When the signal of A2 and B2 all is 0, rear one can only stop motion for the cantilever of signal 0 or do the back motion.
Advantage of the present invention is:
Simple in structure, easy for installation, can guarantee that cantilever prevents collision automatically in the work intersection region, guaranteed that the safety of production is carried out.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is cantilever crane intersection anticollision device scheme drawing of the present invention.
The specific embodiment
Embodiment: the anglec of rotation of cantilever A, the B of two cantilever cranes as shown in Figure 1 is 170 degree, A1, B1 and A3, B3 are respectively left-handed terminal point and the dextrorotation terminal point of cantilever A, B, it is in the Zone R territory that there is the surface area that intersects in the range of movement of two cantilever cranes, column at cantilever crane is installed a cross limit switch, this limit switch contains 4 auxiliary contacts, wherein an auxiliary contact controls that left-handed terminal point, an other subcontrol have arrived the Zone R territory, the 3rd width of cloth contact is that the dextrorotation terminal point is spacing, and cantilever can stop automatically when cantilever moves to A1, A3 and B1, B3.In the time of in the A cantilever is in the Zone R territory (when the A2 signal is 0), the B cantilever crane can not enter (the B2 signal is that 0 o'clock B cantilever crane can not be carried out left-handed signal) in the Zone R territory; In the time of in the B cantilever crane is in the Zone R territory (the B2 signal is 0), the A cantilever can not enter Zone R territory (the A2 signal is that 0 o'clock A cantilever crane can not be carried out right turn signal).Limit switch is installed under the cantilever, between on the column about 250mm, at 3 spacing chis that hit of column welding, is respectively the left-handed terminal point angle control of cantilever, enters the control of Zone R territory, the control of cantilever dextrorotation terminal point angle; Increase a control box newly, be suspended on the next door of original electronic box, can adopt PLC control; Solid drawn pipe of column welding at each cantilever is used for wearing cable, and the while needs on the ground of the ground of two cantilever cranes to be used for connecting the cable of the interlocking signals between two cantilever cranes with the fixing corresponding solid drawn pipe of setscrew.The spacing fixed part fixing, solid drawn pipe of fixing, hit chi adopts Site Welding, and on-the-spot touch-up paint is finished after the welding.Also can adopt other connection modes, enter bolt connection etc.
The above only is the specific embodiment of invention.Protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
