Description
Technical Field
The utility model relates to a detection device, especially a cantilever every single move detection device for stocker.
Background
The existing cantilever pitching detection device of the stacker comprises a pitching detection support, the support is integrally overweight, consumables and installation are troublesome, the weight of the pitching detection device is about 55kg (comprising outsourcing products such as limit switches and standard parts), and the pitching detection device is divided into three parts and is high in cost. Wherein limit switch installation radius is great, and the swivel arm is long (about 1.1 m), and the angle is difficult to the adjustment during installation, wastes time and energy, and the restriction angle error is big in the working process. When the cantilever is pitched to a set limit angle, the contact lever touches the limit switch and is inconsistent with the pitching angle of the cantilever, and when the cantilever is pitched upwards with lag, the pitching angle of the cantilever exceeds the limit angle, so that the vehicle is turned over or the material shed is collided with a safe use range; when the boom is late pitching it can cause the boom head to impact the pile.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a cantilever every single move detection device for stacker that simple structure, with low costs, installation and debugging are convenient, spacing accurate, effectively prevent to collide and the occurence of failure of overturning.
The utility model discloses a cantilever every single move detection device for stacker, include the rocker that meets with the hank axle end of stacker, be fixed with first lance and the second lance that is parallel to each other on the rocker, still include the switch frame with the upper bracket fixed connection of stacker, install on the switch frame with first lance assorted first switch and second switch, first switch and second switch meet with the cantilever every single move control mechanism of stacker.
The swing frame is right-angled; the switch frame is provided with a switch installation arc-shaped groove, and the first switch and the second switch are fixedly installed on one side of the switch frame through bolts and the switch installation arc-shaped groove;
and a third switch connected with a cantilever pitching control mechanism of the stacker is fixed on the other side of the switch frame, and the third switch is matched with the second collision rod.
The utility model discloses a cantilever every single move detection device for stacker, the rocker rotates along with the hank axle when during operation cantilever every single move angle changes, drive first lance and the action of second lance, when the cantilever rotates certain angle, first lance bumps with first switch, control mechanism moves and makes drive cantilever pivoted actuating mechanism stop motion, first lance bumps with the second switch when the cantilever rotates certain angle to opposite direction, control mechanism moves and makes drive cantilever pivoted actuating mechanism stop motion, if the second switch is malfunctioning, the cantilever can continue to rotate, when the second lance bumps with the third switch, cantilever stop motion, the guard action has been played, prevent that the phenomenon of overturning from taking place. The working pitch angle of the cantilever is determined by the mounting position of each switch according to requirements.
The pitching detection device is suitable for side cantilever stacking machines, circular stacking and taking machines and rotary stacking machines. The accuracy of the pitching angle of the stacker directly influences the storage capacity of the stacker and the safety of equipment, when the cantilever tilts upwards, if the working angle exceeds the rated elevation angle, the storage capacity of a stock yard is overloaded, and if the working angle exceeds the rated elevation angle, the equipment is turned over; if the working angle does not reach the rated upper elevation angle, the actual storage capacity of the material pile cannot reach the rated storage capacity, and the user requirements cannot be met. When the cantilever bends downwards, if the working angle exceeds the rated bending angle, the cantilever can touch the material pile to damage the equipment.
The detection device has the advantages of simple structure, low cost, convenience in installation and debugging, accurate limiting, safety and reliability.

Detailed Description
As shown in fig. 1 and 2: the upper frame 7 of the stacker is provided with a hinge shaft 4 through a bearing shell 3 and a bearing support, and the cantilever 1 is fixedly connected with the hinge shaft 4 through a cantilever support 2. The utility model discloses a cantilever every single move detection device for stacker, include the rocker 5 that meets with 4 ends of the hank axle of stacker, rocker 5 is right angle (turning) form, and the end at hank axle 4 is connected to the one end of rocker 5, and the downward fixed connection arc of the other end is fixed with first lance 8 and the second lance 12 that is parallel to each other below the arc. The automatic control device further comprises a switch frame 6 fixedly connected with an upper support 7 of the stacker, a first switch 9 and a second switch 10 which are matched with the first striker bar 8 are mounted on the switch frame 6, and the first switch 9 and the second switch 10 are connected with a cantilever pitching control mechanism of the stacker. Wherein, the switch frame 6 is provided with two upper switch mounting arc-shaped grooves 13, and the first switch 9 and the second switch 10 are fixedly arranged at one side of the switch frame 6 through bolts and the switch mounting arc-shaped grooves 13. The center point of the switch installation arc-shaped groove 13 is positioned on the center line of the hinge shaft 4.
And a third switch 11 connected with a cantilever pitching control mechanism of the stacker is fixed on the other side of the switch frame 6, and the third switch 11 is matched with a second collision rod 12.
The first switch 9, the second switch 10 and the third switch 11 can adjust the installation position according to the working angle required by different stacker cantilevers. As shown in fig. 2: taking the working pitch angle of the cantilever 1 to be-15 degrees to +16 degrees as an example, when the front part of the cantilever is bent downwards by 15 degrees, the first striker 8 touches the first switch 9, which indicates that the cantilever 1 of the equipment is bent downwards to reach the maximum working angle; when the front part of the cantilever 1 tilts upwards by 16 degrees, the first striker 8 touches the second switch 10, which indicates that the cantilever 1 of the equipment tilts upwards to reach the maximum working angle; at this time, if the second switch 10 fails and the cantilever 1 tilts up to 17 °, the second striker 12 touches the third switch 11 to stop the tilting up action, so that the third switch 11 plays a role in protection, and the cantilever 1 is prevented from exceeding the maximum tilting up limit to cause the equipment to overturn. The detection device has the advantages of simple structure, low cost, convenience in installation and debugging, accurate limiting, safety and reliability.
