Abstract
The utility model discloses an electric tension mechanism for a steel wire rope of an underground suspension manned device, and aims at providing an automatic-control electric tension mechanism for a steel wire rope of an underground suspension manned device. The electric tension mechanism comprises a rope containing barrel and a tension sensor, and is characterized in that a steel wire rope is wound on the rope containing barrel, one end of the steel wire rope is fixed on the rope containing barrel, the other end of the steel wire rope is connected with the tension sensor, and one end of a rotating shaft of the rope containing barrel is connected with a motor by a speed reducer. The tension sensor has a serial connection structure. The electric tension mechanism is mainly used for electric tension for the steel wire rope of the underground suspension manned device.
Description
Technical field
The utility model relates to the electronic stretching device of a kind of steel rope, relates in particular to the electronic stretching device of a kind of down-hole overhead manned equipment steel rope.
Background technology
The haulage rope that overhead manned equipment uses under the coal mine must in tension.The tradition stretching device adopts weight stretching device or hydraulic ram stretching device usually, and the problem that the former exists is:
1. tension force can not be regulated: the tension force that the weight stretching device produces depends on the weight of weight, can not carry out tension adjustment.
2. can not carry out automation control.
3. it is big to take up room: stretching device is installed in down-hole overhead manned equipment afterbody, need extend certain space mounting weight mechanism behind tail, and this can increase underworkings length, thereby increases cost and construction period.
The shortcoming that the latter exists is:
There are same shortcoming in hydraulic ram tensioning mode and weight tensioning mode, and be just in light weight, that convenient in carrying is installed is a little.
Summary of the invention
The purpose of this utility model is to provide a kind of energy automatically controlled down-hole overhead manned equipment steel rope electronic stretching device, to overcome above-mentioned shortcoming.
For achieving the above object, technical solution of the present utility model is: the electronic stretching device of a kind of down-hole overhead manned equipment steel rope, comprise and hold rope reel and tension pick-up, it is characterized in that: on the described appearance rope reel 3, be tied with steel rope 4, one end of this steel rope is fixed on and holds on the rope reel 3, and the other end is connected with tension pick-up 5, and an end that holds the rotating shaft 7 of rope reel 3 links to each other with motor 1 by retarder 2.
Described tension pick-up 5 is tension pick-ups of cascaded structure.
The beneficial effects of the utility model are:
1 tension force can be regulated, the setting value of tensile force can freely be set in the control system, also can set different tensile forces to different loads, thereby reaches rational tensioning state, control system detects steel wire rope tension in real time, and compares with preset value.
2 can realize automation control, adopt tension pick-up that steel wire rope tension is detected in real time, and with the testing result input control system, compare with preset value, if tension force reaches predefined lower limit, then automatic starting motor carries out tensioning, when tensile force reaches another setting value, the electrical motor outage, tensioning finishes; In addition can also be to the different tensile force of the different load set of equipment, when the equipment operation load not simultaneously, control system according to the present load situation to steel rope tensile force automatically regulating, thereby reach the purpose of automation control.
3 can save installing space, electronic stretching device can be installed on overhead manned equipment tail top, down-hole, utilize pulley mechanism that the tensioning steel rope is caused electronic stretching device, rationally utilize the remaining space of tail top, need not to extend to the tail rear portion, therefore can save big quantity space, reduce underworkings length.
Two cover tension pick-ups are adopted in 4 sensor failures protections, and when et out of order wherein, two tension pick-ups send to the signal difference of control system, and control system just can be judged sensor fault, realizes the sensor fault auto alarm.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1---motor, 2---retarder, 3---hold rope reel, 4---steel rope, 5---tension pick-up, 6---control system, 7---hold the rope reel rotating shaft, 8---plunging joint, 9---bearing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises appearance rope reel and tension pick-up, it is characterized in that: on the described appearance rope reel 3, be tied with steel rope 4, one end of this steel rope is fixed on and holds on the rope reel 3, the other end is connected with tension pick-up 5, and an end that holds the rotating shaft 7 of rope reel 3 links to each other with motor 1 by retarder 2.
Described tension pick-up 5 is tension pick-ups of cascaded structure.
Control system 6 of the present utility model can preestablish tension force of steel wire, when the needs tensioning, tension pick-up 5 sends signal and gives control system 6, actuating motor 1, motor output shaft drives the rotation of retarder 2 input shafts, through visibly moved rope reel 3 rotations of retarder 2 deceleration rear-guards, steel rope 4 is wrapped in holds on the rope reel 3, make the steel rope tensioning, when tensile force reaches setting value, tension pick-up 5 sends signal and gives control system 6, and this control system is cut off the power supply motor, and tensioning finishes.Retarder 2 adopts the worm type of reduction gearing with auto-lock function, can prevent motor outage back counter-rotating.
Claims (2)
1. electronic stretching device of down-hole overhead manned equipment steel rope, comprise and hold rope reel and tension pick-up, it is characterized in that: on the described appearance rope reel (3), be tied with steel rope (4), one end of this steel rope is fixed on and holds on the rope reel (3), the other end is connected with tension pick-up (5), and an end that holds the rotating shaft (7) of rope reel (3) links to each other with motor (1) by retarder (2).
