The pulse signal output end of code device is connected with the control signal input of rig operations system, the control signal of rig operations system
Output end and motor connection, the rotating shaft of motor are fixedly connected with winch drum shaft, the steel wire rope of winding and lifting in winch drum
Tourist bus connects.
The electronics anti-collision of the oil-well rig tourist bus lifting device of the application protects system to be specifically included during use
Following steps：
Step 1：Build hook height measurement model；
Specifically, first, the theoretical movable length formula of steel wire rope is constructed；Then, increased n-th layer steel on roller is obtained
The accumulated error Δ d of cordn, finally, the theoretical movable length of steel wire rope is missed according to the cumulative errors of every layer of steel wire rope
Difference compensation, obtains the actual movable length formula of steel wire rope, the actual movable length of steel wire rope is hook height.
Tourist bus is lifted from a circle or the big rope of a few circles during zero-bit is lifted up, can be increased on roller, then restricting greatly
When being added on roller, roller actual diameter (i.e. the cumulative thickness sum of diameter of cylinder and steel wire rope) and rolling after big rope superposition
The number of turns error of every layer of steel wire rope in cylinder outside, therefore, it is necessary to which the theoretical movable length of the steel wire rope to calculating carries out error
Compensation.The steel wire rope to calculating theoretical movable length carry out error compensation when, it is necessary to calculate respectively newly increase it is every
The error amount of layer steel wire rope.
Assuming that 5 layers of steel wire rope are added on roller altogether.When in initiation layer, the length of current steel wire rope is measured with meter ruler
l0, then error caused by initiation layer steel wire ropeWhen increasing by 1 layer of steel wire rope on roller, measured with meter ruler
The length l of current steel wire rope1, then error caused by first layer steel wire ropeWhen 2 layers of increase on roller
During steel wire rope, the length l of current steel wire rope is measured with meter ruler2, then error caused by second layer steel wire rope
When increasing by 3 layers of steel wire rope on roller, the length of current steel wire rope is measured with meter ruler
Spend l3, then error caused by third layer steel wire ropeWhen increasing by 4 layers of steel wire rope on roller, with rice
Chi measures the length l of current steel wire rope4, then the 4th layer of error caused by steel wire ropeWhen on roller
When increasing by 5 layers of steel wire rope, the length l of current steel wire rope is measured with meter ruler5, then error caused by layer 5 steel wire ropeThe error delta d that will be calculated0、Δd1、Δd2、Δd3、Δd4、Δd5It is stored in rig operations system
Carried out in system temporary standby.Rig operations system is when the actual movable length to steel wire rope calculates, according in its system
The error of every layer of steel wire rope and the theoretical movable length of this layer of steel wire rope outside the roller of portion's storage, can be to the reason of this layer of steel wire rope
Error compensation is carried out by movable length, draws the actual movable length of this layer of steel wire rope.
The theoretical movable length formula of the steel wire rope isAndWherein n≤6 and n is positive integer, and n is the number of plies of increased steel wire rope on roller, yn、yn-1Point
The length of steel wire rope movement, x when Wei not increase n-layer, n-1 layer steel wire ropes on rollern、xn-1Increase n-layer, n-1 respectively on roller
Encoder pulse number during layer steel wire rope, D is diameter of cylinder, initial steel wire rope number of plies when a is tourist bus zero-bit on roller, and n is
The increased steel wire rope number of plies on roller, d are wirerope diameter, y0For tourist bus zero-bit when steel wire rope length；Increase on the roller
The steel wire rope number of plies n added calculation formula is：Wherein, c be roller on a certain layer steel wire rope number of total coils, roller
Upper increased steel wire rope number of plies n is round down value；
The actual movable length formula of the steel wire rope is
The accumulated errorWherein lnMeter ruler measures during to increase n-layer steel wire rope on roller
Steel wire rope movement physical length.
It is can be seen that according to above-mentioned accumulated error formula in the case where being changed without roller and steel wire rope species (model),
The accumulated error of the roller overall diameter after being once superimposed steel wire rope need to be only compensated in system design process.Afterwards every time more
, all need not be to the roller overall diameter after superposition steel wire rope when the steel wire rope for changing same model or the steel wire rope for changing other models
Compensated again, it is only necessary to initial steel wire rope number of plies a when diameter of cylinder D and tourist bus zero-bit are set on roller.
Step 2：The initial steel wire rope number of plies on roller and trip when obtaining diameter of cylinder, wirerope diameter, tourist bus zero-bit
Encoder pulse number during car zero-bit is simultaneously stored in PLC control system.
Step 3：PLC control system calculates hook height according to the actual movable length formula of steel wire rope, passes through hook height
Degree judge tourist bus whether reach touch deceleration point, on touch a little or under pound a little, if reach touch deceleration point and not less than above touching a little,
The upward strain speed of control tourist bus is decelerated to original 50%；If reach touch a little or under pound a little, control hydraulic disc brake action, make
Roller band-type brake, tourist bus stop movement.
Finally it should be noted that：Above example is only illustrating the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand；Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced
Change；Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model
Among scope.
