Abstract
The utility model relates to a dynamic measurer for the tension of a steel wire rope, which is used for friction type winders with multiple ropes. The device comprises a base, support frames, pressing wheel assemblies, guide rails, lateral plates, a sensor, an advancing mechanism, and a recorder. The base is fixed with foundation, and the support frame is in the shape of a groove; the upper end face and the lower end face thereof are respectively connected with the base board and the base of the guide rail and the base board and the base of the advancing mechanism. The pressing wheel assemblies are connected with the screw rods of the advancing mechanism via the lateral plate and the sensor in sequence. Both ends of the pressing wheel shaft of the pressing wheel assemblies are arranged inside the chute of the guide rail. The utility model can simultaneously conduct a dynamic test for the tension of each hoisting rope during the whole lifting process and carry out the adjustment according to a test result for ensuring the safety of the lifting.
Description
The utility model is a kind of steel wire rope tension dynamic checkout unit, is specially adapted to multi-rope friction hoisting machine.
Multi-rope friction hoisting machine hoisting cable tension imbalance is one of its key property of being different from the single-rope hoisting machine.Keeping uniform tension in order between each wire rope is a major issue that guarantees to promote safety, prolongs rope service-life.Safety regulations has been done strict regulation to steel wire rope tension for this reason.In order to satisfy the requirement of safety regulations, avoid serious accidents such as disconnected rope, must guarantee multi-rope hoist arbitrary hoisting cable tension force with the difference of mean tension be no more than ± 10%.Therefore, must regularly test steel wire rope tension.At present, China estimates method to main employing of multi-rope friction hoisting machine steel wire rope tension test through test, or only limits to measure static tension force.Static tonometry utilizes spring balance to carry out, and its principle is when each rope tension is not of uniform size, and is different with the distance that spring balance is pulled out along the wire rope vertical direction, when each rope tension is consistent, the distance of pulling out equates, utilizes this characteristic, can calculate each rope tension and tension force deviation.And in lifting process, owing to phenomenons such as wire rope slip, wriggling can occur inevitably, all be difficult to reflect truly, exactly the load condition of each hoisting cable with estimate method and static measurement method through test, and can not reflect steel wire rope tension dynamic situation in the lifting process.
The purpose of this utility model is for multi-rope friction hoisting machine provides a kind of steel wire rope tension dynamic checkout unit, both can carry out dynamic test simultaneously to each hoisting cable tension force of whole lifting process, can carry out static test again.Then,, adjust,, guarantee to promote safety with heavy economic losses and the personnel casualty accidents of avoiding being caused because of the tension force inequality according to measurement result.
The steel wire rope tension dynamic checkout unit is made up of base, support, pinch roller assembly, guide rail, side plate, sensor, propulsive mechanism and registering instrument etc.Base is connected with ground by foundation bolt, and support is a trench structure, and its lower surface is by being bolted on the base T type groove, and the upper surface is connected with bolt with the base plate of guide rail and propulsive mechanism.The wheel pressing shaft two ends of pinch roller assembly are contained in the guide rail chute, and wheel body can rotate around wheel pressing shaft also can be along the certain angle of wheel pressing shaft vertical direction beat.The screw rod of the wheel pressing shaft of pinch roller assembly, side plate, sensor and propulsive mechanism links to each other successively.The handwheel of rotation propulsive mechanism can make pinch roller assembly move forward and backward along guide rail chute direction.
The designed steel wire rope tension dynamic checkout unit of the utility model is applicable to multi-rope friction hoisting machine, also can be used for the single-rope hoisting machine.It has test normally promote, transfer and the brake hard operating mode under the function of wire rope dynamic tension and static tension force, its measuring accuracy height, simple in structure, fitting operation is convenient, can under the hoister normal operating conditions, test, by regularly to steel wire rope tension measure, examination and maintenance, adjustment, can guarantee that hoister runs well, guarantee to promote safety.
