Detection device.
Background technique
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., wirerope 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 steel wire rope looseness or tight rope can be caused when card tank phenomenon 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 operation safety is promoted.Mesh
Before, steel wire rope tension detection mode is to install pressure transmitter on more rope race wirerope balancing cylinders mostly, is become by pressure
Device measurement oil pressure is sent to obtain corresponding tension, but pressure transmitter has the following deficiencies: 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 work is easy to draw under high-pressure situations
Phenomena such as playing oil leak also will affect 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
Signal 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.
Summary of the invention
The purpose of this utility model is to provide a kind of more rope race skip-cage steel cable tension testers, detection essences
Degree is high and easy for assemble or unload.
What the purpose of this utility model was such to reach, a kind of more rope race skip-cages are filled with steel wire rope tension detection
It sets, more rope race skip-cages include one group of wirerope, are provided in the lower end of each wirerope for balance rope pair
The steel wire hang balance mechanism of skip-cage active force, the steel wire hang balance mechanism are hinged on coupling mechanism,
The top of skip-cage is arranged in the coupling mechanism, and the steel wire hang balance mechanism includes hydraulic cylinder for adjusting rope, described
Hydraulic cylinder for adjusting rope be arranged in vertical state, which is divided into epicoele and cavity of resorption, the epicoele for cylinder chamber by piston
It is interior to be filled with hydraulic oil, the intracavitary piston rod being provided with for pushing piston to move up and down under described, steel wire hang balance
Mechanism is on bottom wall and corresponding hydraulic cylinder for adjusting rope is arranged right below movable cushion block, it is characterised in that: the steel wire rope tension inspection
Surveying device includes pressure sensor, and the pressure sensor is arranged between the bottom end of piston rod and movable cushion block.
It further include the signal acquisition circuit being sequentially connected in series, AD in a specific embodiment of the utility model
Conversion circuit, single-chip data processing circuit and wireless data transmitting line, the signal acquisition circuit connection pressure
Force snesor, the wireless data transmitting line carry out data transmission by wireless communication with well head fixed equipment.
Due to the above structure, compared with prior art, having the beneficial effect that can be direct for the utility model
It is high to measure pressure, the pilot process not converted, therefore measurement accuracy；Output signal is mv original signal, is not needed in
Between circuit converted, therefore failure rate is low；It can be used for independent measurement, to battery loss very little, 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 is mounted and dismounted all very square
Just, it will not influence to change rope and adjust and restrict；Anti-overload ability is fabulous, and precision is high, and whether oil path in oil cylinder, which locks, will not influence every rope
Tension detection.
