Abstract
Description
Technical Field
[0001] The utility model relates to a tool which can conveniently measure the thickness of the bottom of a coal pile at a coal terminal, and belongs to the technical field of auxiliary tools for bucket wheel reclaimers. Background Art
[0002] Bucket wheel reclaimer is the main equipment for reclaiming operations in coal terminals, ore terminals, power plants and other enterprises. The ground of the yard has settled due to the long-term storage of goods. The uneven surface with low middle and high sides is formed. It is difficult to control the height of the bucket wheel and the ground when the bucket wheel reclaimer is reclaiming. When the arm wheel bucket is lowered too low, the bucket wheel reclaimer bucket will gnaw the ground when reclaiming materials to both sides, which will cause great damage to the equipment and easily cause downtime for maintenance. After the bucket wheel is damaged, maintenance will cause 3-4 hours of downtime, seriously affecting production operations; when the arm wheel bucket is too high from the ground, the remaining pile bottom is too thick after reclaiming, and the stacking time using the loader increases, affecting production efficiency. At present, the visual reference method is used, which has large deviations due to different personnel. In the face of the uneven settlement of the yard, it is necessary to reasonably control the thickness of the remaining pile bottom to prevent the bucket wheel reclaimer bucket from gnawing the ground, causing damage, deformation, and scratching of the steel structure, thereby reducing the impact of equipment downtime on production operations. Therefore, it is very necessary to design a tool that is convenient for measuring the thickness of the coal pile bottom. Utility Model Content

[0018] Figure 1 It is shown that the measuring rod 1 of the utility model is the main body of the measuring tool. The rod body of the measuring rod 1 can be a round tube or a round rod, or a square steel. The material can be steel or aluminum alloy. The upper end of the measuring rod 1 is installed with a handle 2. The lower end of the measuring rod 1 is sharp. By pressing the handle 2, the measuring rod can be inserted into the coal pile for measurement. There is a scale 3 along the length direction on the measuring rod 1. The zero point of the scale 3 is the lower end of the measuring rod 1. After the measuring rod 1 is inserted into the coal pile, the thickness of the coal pile can be understood according to the value of the scale 3. The guide plate 5 is mounted on the lower part of the measuring rod 1 to control the insertion direction of the measuring rod 1. Two support plates 9 are connected to the two ends of the guide plate 5, and together with the guide plate 5, they support the upper surface of the coal pile.

[0022] Figure 2 ,3 4 shows that the upper ends of the two support plates 9 have shaft holes respectively corresponding to the shaft holes 8 of the side plates 7 of the guide plate 5, and the rotating shaft 10 passes through the shaft holes of the side plates 7 and the support plates 9 to rotatably connect the side plates 7 and the support plates 9. One end of the rotating shaft 10 has an end cover 11, and the other end has a pin hole. During installation, one end of the rotating shaft 10 is inserted into the shaft hole 10, the end cover 11 blocks the outside of the shaft hole 10, and the other end of the rotating shaft 10 extends out of the side plate 7, and the pin 12 is inserted into the pin hole to position the rotating shaft 10.
[0023] Figure 4 It is shown that a stopper 4 is fixed to the lower part of the measuring rod 1, the stopper 4 is located below the guide plate 5, the stopper 4 is stuck below the guide hole 6, and the distance from the stopper 4 to the lower end of the measuring rod 1 matches the length of the support plate 9.
