Description
Technical field
The utility model relates to a kind of checkout gear that is used to detect fully-mechanized mining working coal-winning machine position.Belong in the full automatic combine coal mining unit, cooperate the support electrohydraulic controller to realize moving frame and the coal-winning machine position detecting device that adopts with machine.
Background technology
The full automatic combine coal mining unit is the development trend of following coal industry, and one of its key technology is exactly to realize that the automatic of electrohydraulic control system moves frame with machine.That realizes hydraulic support moves frame with machine automatically, and it is particularly important accurately to obtain the coal-winning machine positional information.The support electrohydraulic control system is carried out the control corresponding instruction according to the coal-winning machine positional information of central control unit transmission, thereby realizes the interlock of support and coal-winning machine.The checkout gear that uses has following mode at present:
A kind of is note tooth method.Utilize the gear counting principle to obtain the gear revolution, obtain travel distance, calculate the frame number of coal-winning machine place working face again according to set spacing according to the gear girth.Then, this positional information is passed to the support electrohydraulic control system.This checkout gear is made up of position probing transmitter and position probing receiver.Transmitter is installed on the coal-winning machine, mainly finishes coal-winning machine walking gear counting and counting are proofreaied and correct.And positional information issued receiver in the radio wave mode.Receiver carries out logical process after receiving relevant information, sends the support electrohydraulic control system to by communication cable then.Whole system is that a transmitter and several receivers are formed, and by the wireless short-distance transmission, increases the fail safe of system, but has some shortcomings simultaneously: the one, and measurement mechanism poor accuracy, coal-winning machine move back and forth and cause losing of pulse.The 2nd, during power down, move holder function with machine and disappear in the running.The 3rd, communication interface does not match with support electricity hydraulic control both at home and abroad.The 4th, radio wave very easily is interfered in the complicated rugged environment in down-hole, and reliability is low.
A kind of is infra-red method.An infrared transmitter is installed on the coal-winning machine front shroud.Every hydraulic support is equipped with an infrared receiver.This system reaches area, refreshing east abroad and combines the condition of adopting and use more extensively in the colliery preferably, and reliability is higher.But because complete equipment cost height can not spread to general colliery.And distance can not be oversize between receiver and the reflector, and the words of reflector and receiver misalignment can't operate as normal.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of accuracy of detection height, good reliability, the omnidistance device that detects the coal-winning machine position of realization are provided, and solves problems such as the cost height, the reliability that exist in the prior art are low.
The technical solution of the utility model is:
A kind of coal-winning machine position detecting device, this device is for to install rotary encoder on the coal mining arbor.
Described coal-winning machine position detecting device, rotary encoder is fixed on coal-winning machine hubcap place by the encoder fixture, the input of rotary encoder connects the elasticity connecting axle, rotary encoder is connected with the coal mining arbor by the elasticity connecting axle, and the output of rotary encoder connects central control unit by lead.
Income effect of the present utility model is:
1, the utility model coal-winning machine position detecting device, it mainly is to detect the positional information of coal-winning machine, be transferred to central control unit by data communication line, central control unit is through giving the support server with message transmission after the logical operation, thereby that realizes fully-mechanized mining working moves frame with machine, reduce underground labour's labour intensity, enhance productivity.
2, the utility model encoder is fixed on coal-winning machine hubcap place, links together by elasticity connecting axle and coal mining arbor.During the coal-winning machine walking, rotary encoder is by detecting the rotating cycle of coal mining arbor, transfer data to central control unit then in real time, central control unit sends instruction through giving the support server after the logical operation, carry out the corresponding frame instruction of passing, thereby realize the automatic control of entire working surface, improved production efficiency, reduce the labour intensity of coal miner.Has practicality widely.
3, the utility model sends to central control unit with the positional information of coal-winning machine in real time, and central control unit is through sending to the support electrohydraulic control system with corresponding information after the logical operation, and that realizes support and coal-winning machine follows the machine automation.This installs strong interference immunity, and is reliable, efficient is high, has practicality widely.
Description of drawings
Fig. 1 is the structural representation of the utility model position detecting device.
Among the figure, 1 rotary encoder; 2 fixtures; 3 elasticity connecting axles; 4 data communication line; 5 central control units; 6 coal mining arbors; 7 coal-winning machine hubcaps.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, the utility model fully-mechanized mining working coal-winning machine position detecting device is made up of the rotary encoder 1, encoder fixture 2, elasticity connecting axle 3, data communication line 4, the central control unit 5 that are installed on the coal-winning machine.Rotary encoder 1 is fixed on coal-winning machine hubcap 7 places (as: bolt connection) by fixture 2, the input of rotary encoder 1 connects elasticity connecting axle 3, rotary encoder 1 is connected with coal mining arbor 6 by elasticity connecting axle 3, and the output of rotary encoder 1 connects central control unit 5 by lead.
During installation, earlier rotary encoder 1 is installed on the encoder fixture 2, rotary encoder 1 connects elasticity (connections) axle 3, with elasticity (connection) spools 3 with fixture 2 be fixed on coal-winning machine hubcap 7 places after coal mining arbor 6 is connected.
During the coal-winning machine walking, rotary encoder 1 is by detecting the rotating cycle of coal mining arbor 6, by data communication line 4 data (coal-winning machine positional information) are transferred to central control unit 5 in real time then, central control unit 5 sends instruction through giving the support electrohydraulic control system after the logical operation, carry out the corresponding frame of passing and instruct, thereby the automatic control of realization entire working surface has improved production efficiency, reduce the labour intensity of coal miner, have practicality widely.
When dismantling this device, because rotary encoder 1 is fixed on the encoder fixture 2, encoder fixture 2 is fixed on coal-winning machine hubcap 7 places.Only need to pull down encoder fixture 2, and then pull down rotary encoder 1, improved maintainability like this from coal-winning machine hubcap 7.
