Description

Technical Field

[0001] The utility model relates to the field of bucket wheel machine cantilever anti-collision equipment, in particular to an integrated pulse ranging anti-collision instrument. Background Art

[0002] Bucket wheel stacker-reclaimer refers to a kind of high-efficiency loading and unloading machinery used for continuous conveying in large dry bulk cargo yards that can both stack and retrieve materials. It consists of a belt conveyor arm that can pitch and swing horizontally, a bucket wheel at its front end, a frame, and an operating mechanism. The belt can run in both directions. When retrieving materials, the bucket wheel takes the materials and sends them out through the conveyor arm. When stacking materials, the goods transported by the main conveyor are thrown into the yard through the conveyor arm.

[0003] The development of domestic bucket wheel stacker reclaimers has basically gone through three stages. In the 1960s and 1970s, China began to design small bucket wheel stacker reclaimers. Typical models include 3025 and 8030, with reclaiming outputs of 300t / h and 800t / h, and turning radius of 25m and 30m respectively. The 1980s and 1990s were the second stage of the development of bucket wheel stacker reclaimers. Newly built bulk material yards such as steel mills and power plants gradually adopted large bucket wheel stacker reclaimers for bulk material stacking and transportation. For example, in Shanghai Baosteel and Qinhuangdao Wharf Material Yard, bucket wheel stacker reclaimers have a reclaiming output of 2000t / h and a turning radius of 25m and 30m. to 40m. Limited by the domestic conditions at that time, the construction of these material yard conveying equipment was mostly cooperative manufacturing or imported complete machines, and even the entire bulk material conveying system was introduced from abroad. After 2000, the domestic bucket wheel stacker and reclaimer has developed into a new stage. So far, domestic manufacturers have the design and manufacturing capabilities of bucket wheel stacker and reclaimer series products with a production capacity of 300 to 6000t / h and a rotation radius of 25 to 60m. During this stage, foreign manufacturers still occupy a certain share, but domestic manufacturers have mastered considerable technology and production capacity, and have occupied the mainstream position in the domestic market with their service and price advantages, and gradually moved towards the international market.

[0004] Due to the huge size of bucket wheel machines, it is necessary to observe in real time whether there is a possibility of collision within its working range during operation. Observation by visual means alone will greatly increase the workload of operators. Therefore, bucket wheel machines often need to install anti-collision instruments (laser rangefinders) at specific locations to assist in real-time monitoring and issue alarm information when necessary; traditional anti-collision instruments (laser rangefinders) often have certain requirements for the working environment. For example, if dust and other objects are adhered to their receivers and transmitters, it will affect their measurement performance or cause false alarms. The working environment of bucket wheel machines happens to be a high-dust environment, so the receiver and transmitter of the anti-collision instrument (laser rangefinder) need to be cleaned from time to time.
