The measurement of the elevator car roof reverse rope wheel can be carried out according to the following steps: 1. Prepare measuring tools, such as tape measure (steel tape measure is suitable), calipers, angle measuring tools, etc. 2. Measuring diameter: - To measure the outer diameter, fix the tape measure at the center of the wheel, then rotate the wheel, record the circumference of the wheel, and then calculate the diameter of the wheel according to the circumference. You can also use the tape measure to directly measure the outer diameter at the widest position of the outer ring of the reverse rope wheel and record the result. This value is related to the rated load of the elevator. - If the elevator uses a multi-rope reverse rope system, the inner diameter of the reverse rope wheel needs to be measured to determine the number and specifications of the lifting rope. The measurement method is the same as the outer diameter measurement. 3. Measuring width: Use calipers to measure the width of the wheel, including the thickness of the rim and tire. 4. Measuring bearing-related size (option): After determining the diameter and width of the wheel, you can measure the diameter and depth of the bearing hole, as well as the gap between the wheel and the bearing hole. 5. Measuring the included angle between the reverse rope wheel and the vertical direction: Use an angle measuring tool to measure the included angle between the surfaces on both sides of the reverse rope wheel and the vertical direction. The included angle between the two surfaces and the vertical direction should be equal. The measurement result can be used to determine whether the reverse rope wheel is inclined or not. 6. Damage inspection: observe whether there are obvious signs of wear, cracks, and distortion on the surface of the anti-rope wheel. If there are, repair or replace it in time. 7. Data recording: Record and organize the measurement results into a standard measurement report, and submit it to the elevator engineer for confirmation and inspection.

Reflection, summary and improvement of the fruit-picking music game in the middle class of kindergarten

The following is a summary and improvement of the kindergarten's fruit-picking music game: ** I. Reflection and conclusion ** 1. ** Strengths ** - ** Interesting ** - The theme of the game,"Picking Fruits," was suitable for children's lives and could arouse their interest. In the process of simulating the process of picking fruits, children could experience the fun similar to life scenes, such as picking fruits from different directions (top, left, right, back). This design increased the fun and variety of the game. - The integration of music elements made the entire game more lively. The child could turn his wrist and pick fruits according to the beat of the music, making the game full of rhythm with the coordination of movements and music. - ** Achievement of education goals ** - In terms of emotional goals, children could show a happy mood when picking fruits. Finally, when they saw that they had picked a lot of fruits, they could also feel joy. This helped to cultivate a positive emotional experience for children. - In terms of movement skills, the child learned a variety of fruit-picking movements, such as single-handed picking, two-handed picking, cooperative picking, etc., and could operate in different situations (picking the basket, putting the basket on the ground and picking with both hands), training the child's wrist rotation, arm extension and other movement skills, improving physical coordination. - In terms of social interaction, the cooperation in picking fruits promoted communication and cooperation between children. Children needed to discuss who would hold the basket and pick the fruits, which helped to cultivate children's sense of cooperation and communication skills. 2. ** Not enough ** - ** Individual differences ** - During the game, the difference in the development level of children's individual movements might not be fully taken into account. For example, for some children whose wrists were not flexible enough or whose arms were weak, they might have difficulty picking fruits, and the individual guidance for these children during the teaching process might not be enough. - ** Game difficulty progression ** - Although there were many segments in the game, the progression of difficulty was not scientific enough. The transition from a single action to a combination action may be a little rushed, and some children may not be able to adapt well. For example, when picking fruits with one hand and changing the position of picking fruits with both hands, some children might be flustered. - ** Teaching feedback ** - In the evaluation stage, the feedback was relatively simple. It was mainly based on the teacher's evaluation. There were few mutual evaluations between children, which might limit the children's in-depth understanding of their own and other people's behavior. ** II. Modification measures ** 1. ** For individual differences ** - Before the game began, the child's movement development level could be observed and evaluated, such as wrist flexibility, arm strength, and so on. For children with weaker motor development, more time and individual guidance could be given in the basic movement practice session. For example, some auxiliary practice tools, such as small paper balls, could be provided to let the children practice grasping and turning the small paper balls to enhance the flexibility of the wrist. 2. ** Game difficulty increases ** - Redesigning the difficulty of the game segment. Before the transition from picking fruits with one hand to picking fruits with both hands, one could add a step of picking fruits with one hand but increasing the number of fruits or the frequency of picking, so that the child could be more skilled and confident in picking fruits with one hand. Then, he introduced the process of picking fruits with both hands. When picking fruits with both hands, he first fixed the position. After the child mastered it, he would practice changing the position. 3. ** Teaching feedback ** - Adding a part of the children's mutual evaluation in the evaluation segment. For example, after working together to pick the fruit, the children were asked to observe each other and tell each other the advantages of the cooperation process, such as "I think my little friend holds the basket very firmly, so it is very convenient for me to pick the fruit." The teacher would make a summary evaluation on the basis of the children's mutual evaluation. This would allow the children to understand the behavior norms and excellent performance in the game from different angles. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
