Abstract
The utility model discloses a cantilever crane cross anti-collision device. The cantilever crane cross anti-collision device is characterized by comprising a limit switch on a cantilever crane pillar, a limit collision ruler and a control box, wherein the control box is connected with the limit switch. The cantilever crane cross anti-collision device is simple in structure and convenient to install, and can ensure that a cantilever can automatically prevent collision in a work cross area, thus ensuring the safety in production.
Description
Technical field
The utility model 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 on using, thereby, such problem has appearred, there is the phenomenon of two forked workings in the radius of operating area, the technological requirement that anticollision between cantilever so just occurred, conventional is all to adopt manual control, so very dangerous.
The utility model content
The utility model purpose is: provide the cantilever crane of the collision problem in the working process between a kind of simple in structure, solution cantilever easy to use to intersect anticollision device.
The technical solution of the utility model is: a kind of cantilever crane intersection anticollision device, it is characterized in that, and comprise the limit switch that is positioned on the cantilever crane column, spacing chi and the control box of hitting, described control box is connected 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.
The utility model comprises the following steps:
(1) determine 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) when cantilever entered in the Zone R territory, the signal of intersection region point A2 and B2 was 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.
The utility model has the advantages that:
Simple in structure, easy for installation, can guarantee that cantilever prevents collision automatically in the intersection region of working, guaranteed that the safety of production is carried out.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is cantilever crane intersection anticollision device schematic diagram of the present utility model.
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, a cross limit switch is installed on the column of cantilever crane, 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 contact is that the dextrorotation terminal point is spacing, and cantilever can stop automatically when cantilever moves to A1, A3 and B1, B3.When the A cantilever is in the Zone R territory (when the A2 signal is 0), the B cantilever crane can not enter in the Zone R territory (the B2 signal is that 0 o'clock B cantilever crane can not be carried out left-handed signal); When 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 arranged under cantilever, 250mm left and right on column, and 3 spacing chis that hit of welding on column are respectively the left-handed terminal point angle of cantilever and control, and enter Zone R territory control, and cantilever dextrorotation terminal point angle is controlled; Newly increase a control box, be suspended on the side of original electronic box, can adopt PLC to control; Solid drawn pipe of welding is used for wearing cable on the column of each cantilever, and the while needs to be used for connecting the cable of the interlocking signals between two cantilever cranes with the fixing corresponding solid drawn pipe of setscrew on the ground of the ground of two cantilever cranes.The spacing fixed part fixing, solid drawn pipe of fixing, hit chi adopts Site Welding, and after welding, on-the-spot touch-up paint is completed.Also can adopt other connection modes, enter bolt connection etc.
The above is only the specific embodiment of utility model.Protection domain of the present utility model is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the utility model discloses, and the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
Claims (4)
