Description

Cantilever Pitch Detection Device for Stacker

technical field

The utility model relates to a detection device, in particular to a cantilever pitch detection device used for a stocker.

Background technique

The existing stocker cantilever pitch detection device includes a pitch detection bracket, which is too heavy as a whole, which is not only consumable but also troublesome to install. Composed of three parts, the cost is high. Among them, the installation radius of the limit switch is large, the rotating arm is long (about 1.1m), and the angle is not easy to adjust during installation, which is time-consuming and laborious, and the limit angle error is large during the working process. When the cantilever is pitched to the set limit angle, it may cause the touch rod to touch the limit switch and the pitch angle of the cantilever is inconsistent. When the cantilever is raised with a lag, it will cause the cantilever pitch angle to exceed the limited angle and cause the car to overturn or collide with the shed. Safety Scope of application; when the cantilever lags behind, it will cause the cantilever head to collide with the material pile.

Utility model content

The purpose of the utility model is to provide a cantilever pitch detection device for a stacker with simple structure, low cost, convenient installation and debugging, accurate position limit, and effective prevention of collision and rollover accidents.

The cantilever pitch detection device for the stacker of the present utility model comprises a pendulum connected to the end of the twisted shaft of the stacker, on which a first ram and a second ram parallel to each other are fixed, It also includes a switch frame fixedly connected with the upper bracket of the stocker, and a first switch and a second switch matching the first striker are installed on the switch frame, and the first switch and the second switch are connected with the cantilever of the stocker. The pitch control mechanisms are connected.

The swing frame is in a right-angle shape; the switch frame is provided with a switch mounting arc groove, and the first switch and the second switch are fixedly installed on one side of the switch frame through bolts and switch mounting arc grooves;

The other side of the switch frame is fixed with a third switch connected with the cantilever pitch control mechanism of the stocker, and the third switch matches the second striker.

The utility model cantilever pitch detection device used for stackers, when the cantilever pitch angle changes during operation, the pendulum rotates with the twisted shaft, driving the first ram and the second ram to move, when the cantilever rotates to a certain angle , the first striker collides with the first switch, the control mechanism acts to stop the drive mechanism that drives the cantilever to rotate, when the cantilever rotates to a certain angle in the opposite direction, the first striker collides with the second switch, the control mechanism acts to make the drive The driving mechanism of the cantilever rotation stops running. If the second switch fails, the cantilever can continue to rotate. When the second striker collides with the third switch, the cantilever stops rotating, which plays a protective role and prevents the rollover phenomenon from occurring. The working pitch angle of the cantilever is determined by the installation position of each switch as required.

The pitch detection device is suitable for side cantilever stackers, circular stackers and reclaimers, and rotary stackers. The accuracy of the stacker’s pitch angle directly affects the storage capacity of the stockpile and the safety of the equipment. When the cantilever is tilted upward, if the working angle exceeds the rated upward angle, it will cause the storage of the stockyard to be overloaded, and the angle exceeding the rated angle is too large Sometimes it will cause the equipment to overturn; if the working angle does not reach the rated upward angle, the actual storage of the stockpile will not reach the rated storage, which cannot meet the needs of users. When the cantilever is down, if the working angle exceeds the rated down angle, the cantilever will touch the material pile and damage the equipment.

The detection device has the advantages of simple structure, low cost, convenient installation and debugging, accurate limit position, safety and reliability.

Detailed ways

As shown in Figures 1 and 2: 7 is the upper frame of the stacker, on the upper frame 7 there is a hinged shaft 4 supported by the bearing shell 3 and the bearing, and the cantilever 1 is fixedly connected with the twisted shaft 4 by the cantilever bracket 2. The cantilever pitch detection device for the stocker of the present utility model comprises a pendulum 5 connected to the end of the twisted shaft 4 of the stocker, the pendulum 5 is in the shape of a right angle (corner), and one end of the pendulum 5 is connected to The end of the twisted shaft 4 and the other end are fixedly connected to the arc plate downwards, and the first lance 8 and the second lance 12 parallel to each other are fixed below the arc plate. Also comprise the switch frame 6 that is fixedly connected with the upper bracket 7 of stacker, the first switch 9 and the second switch 10 that match with the first striker 8 are installed on the switch frame 6, the first switch 9 and the second The switch 10 is connected with the cantilever pitch control mechanism of the stocker. Wherein the switch frame 6 is provided with two upper switch installation arc grooves 13, and the first switch 9 and the second switch 10 are fixedly installed on one side of the switch frame 6 through bolts and switch installation arc grooves 13. The center point of the switch installation arc groove 13 is located on the center line of the twisted shaft 4 .

The other side of the switch rack 6 is fixed with a third switch 11 connected with the cantilever pitch control mechanism of the stocker, and the third switch 11 matches the second striker 12 .

The installation positions of the first switch 9, the second switch 10 and the third switch 11 can be adjusted according to the working angles required by different stacker booms. As shown in Figure 2: Taking the working pitch angle of the cantilever 1 -15°~+16° as an example, when the front part of the cantilever is pitched down by 15°, the first striker 8 touches the first switch 9, indicating that the cantilever 1 of the equipment is pitched down to reach The maximum working angle; when the front part of the cantilever 1 is tilted up by 16°, the first ram 8 touches the second switch 10, indicating that the equipment cantilever 1 has reached the maximum working angle; if the second switch 10 fails at this time, the cantilever 1 continues When leaning up to 17°, the second striker 12 will touch the third switch 11 and stop the upward movement, so the third switch 11 plays a protective role to prevent the cantilever 1 from exceeding the maximum upward tilt and causing the equipment to overturn. The detection device has the advantages of simple structure, low cost, convenient installation and debugging, accurate limit position, safety and reliability.
