Description
Technical Field
The utility model relates to a special equipment technical field, concretely relates to chain tension measurement system.
Background
The mechanical parking equipment is a general name of equipment for transporting and parking automobiles in a mechanical garage and can be divided into lifting and horizontal moving type parking equipment, vertical circulating type parking equipment, roadway stacking type parking equipment, horizontal circulating type parking equipment, multilayer circulating type parking equipment, plane moving type parking equipment, a special lifter for automobiles, vertical lifting type parking equipment, simple lifting type parking equipment and the like. With the continuous rising of the automobile holding amount in China, the mechanical parking equipment has a huge potential market compared with the continuous shortage of the parking space proportion in each large city. By 2015, 491 mechanical garage cities are owned by China, the total number of established body garage projects exceeds 14.4 thousands, and the total number of berths is 336 thousands.
Behind the rapidly growing numbers are the enormous potential safety hazards to regulatory authorities, usage units, manufacturing units and maintenance units. The two-in-three vehicle overturning accidents are mostly caused by lifting and transverse moving type parking equipment, the lifting and transverse moving type parking equipment accounts for about 70% of all mechanical parking equipment, and the lifting and transverse moving type parking equipment is common mechanical parking equipment. In accidents, a chain which is a key part of the parking equipment is often involved. In the lifting and transverse moving type parking equipment, a chain is mainly used for transmitting a lifting motor to a transmission shaft and lifting a vehicle carrying plate. The chain is used as an important stress part, and the failure or the breakage of the chain can directly cause the instability and the overturn of the vehicle carrying plate. Therefore, the stress condition of the chain in the using process can be measured by detecting the tension of the chain, and the existing hidden danger can be found.
At present, the detection method and judgment basis for the chain tension of the mechanical parking equipment have no relevant standards and requirements, but serious consequences are easily caused when the chain tension is too large in the reflection of actual inspection and manufacturing installation units, and the vehicle carrying plate or the carrier is easily caused to fall due to the breakage of the chain. The domestic detection of the chain tension basically adopts an on-line detection mode. The foreign research on chain tension focuses more on the application aspect, and mainly adjusts the tension of the chain after the tension value is obtained by using a monitoring device.
In summary, the research on chain tension at home and abroad at present belongs to the field of online detection, and the emphasis is placed on adjusting the using state of the chain by measuring the chain tension. The method has the advantages that the soft measurement technology is utilized for real-time detection and real-time feedback, so that the production can be guided better, and unnecessary loss is reduced. However, this detection cannot be implemented for the chain detection of the mechanical parking equipment, which requires immediate measurement and does not require real-time transmission. Therefore, it is more important to obtain the tension value of the chain by simple operation for the inspection mechanism and the maintenance unit of the mechanical parking equipment.
