Description
Technical field
The invention belongs to mine hoisting technical fields, and in particular to a kind of more rope race skip-cage steel wire rope tension detections
Device.
Background technology
Boom hoist cable is an important component in coal mine lifting transportation system.For coal mine lifting machine, such as dustpan
Bucket or cage etc., steel wire rope is in lifting process, due to the uncertainty of load, the actual tension and its variation feelings that are born
Condition is extremely complex, such as：Elevator occurs that when card tank phenomenon steel wire rope looseness or tight rope can be caused in the process of running；Or
Elevator is due to overloading, the operation of super tension can cause steel wire iope slippage, so as to cause the serious accidents such as " big and heavy stone tank ", " pendant bucket ".By
This, steel wire rope tension detection equipment just seems more important.
More rope race skip-cages main bottleneck that steel cable tension tester is always that coal mine job safety is promoted.Mesh
Before, steel wire rope tension detection mode is to install pressure transmitter on more rope race steel wire rope balancing cylinders mostly, is become by pressure
Device is sent to measure oil pressure to obtain corresponding tension, but pressure transmitter has the following defects in actual use：First, pressure becomes
Conversion is had to pass through after sending device to measure oil pressure can just measure tension；Second, pressure transmitter is operated under high-pressure situations, it is easy to draw
Phenomena such as playing oil leak can also influence the effect of balancing cylinder when serious, cause safety accident；Third, the operating current needed is big,
If four transmitters are set by each balancing device and are calculated, battery power consumption will be greatly increased；Fourth, measurement accuracy is poor, it is defeated
The signal gone out, which has to pass through transmitter conversion amplification, can just be converted into current signal, therefore fault point can be more；Fifth, equilibrium oil
Cylinder goes here and there rope in order to prevent, and side connection, the other side is lockked, wherein the side being connected to cannot truly detect every rope
Tension；Thirdly, pressure transmitter anti-overload ability is poor.
In view of above-mentioned prior art, the applicant has made beneficial design, technical solution described below be
It is generated under this background.

Sensor, the wireless data transmission circuit carry out data transmission by radio communication with well head fixed equipment.
The present invention compared with prior art, has an advantageous effect in that due to the above structure,：It can directly measure
Pressure, the pilot process not converted, therefore high certainty of measurement；Output signal is mv original signals, need not be by intermediate electricity
Road is converted, therefore failure rate is low；It can be used for independent measurement, to battery loss very little, the use of battery can be greatly improved
Service life；It is installed on oil cylinder piston top, is not had any impact to former balancing cylinder, and installation and removal are all very convenient, no
It can influence to change rope and adjust rope；Anti-overload ability is fabulous, and precision is high, and whether oil path in oil cylinder locks the tension inspection for not interfering with every rope
It surveys.
