Abstract
The utility model discloses a shuttle car cable reel with a remote limit control system, comprising a control circuit, a cable reel, cables wound on the reel and a switch on the reel which is automatically turned on when the cable is fully loosen, wherein one end of the switch is connected in series with the control circuit, and the other end is connected with a control relay coupled with a transformer, and the control relay is connected in series a main circuit breaker. The utility model can be effectively stopped the when cable is fully loosen on the reel for protection of the cable reel and the cable.
Description
Technical field
The utility model relates to a kind of shuttle car cable drum that has long-range spacing control system, relates in particular to a kind of shuttle car cable drum that has long-range spacing control system that is used at coal mine operation.
Background technology
At present,, objectively require improving constantly of raw coal productive capacity along with coal in China energy starved problem becomes increasingly conspicuous, therefore also just more and more higher to the security requirement of the continuous working of downhole production equipment.Usually shuttle car rolls by cable drum and will twine thereon cable and scatter or roll by three-phase alternating-current supply under the coal mine, moves forward and backward to adapt to shuttle car.But; there are the following problems when existing shuttle car used in the down-hole: in the process of advancing when the cable at cable drum place all clears; shuttle car can move under the situation without any protection or prompting; thereby break cable and cause electrical hazard and cause the damage of reel; this has not only increased the maintenance cost of shuttle car but also has failed to meet the time limit of a project, and then production efficiency is descended.
Therefore, be necessary to design a kind of new shuttle car cable drum in fact, to overcome above-mentioned defective.
The utility model content
The purpose of this utility model be to provide a kind of can auto-stop can cable all clears on reel the time with the shuttle car cable drum that has long-range spacing control system of the effect that reaches protection reel and cable.
For achieving the above object, shuttle car cable drum of the present utility model is such design-calculated:
A kind of shuttle car cable drum that has long-range spacing control system, the reel switch that it comprises control circuit, cable drum, be wrapped in cable on the cable drum, be located on this cable drum and can scatter fully and open automatically because of cable, this reel switch one end is connected with described control circuit, and the other end and a control relay are in series, this control relay and control transformer coupling, described control relay further is in series with a line circuit breaker.
Whereby, when this shuttle car cable drum that has long-range spacing control system can cable all clears on cable drum effectively, make its auto-stop with protection cable drum and cable.
Description of drawings
Below in conjunction with accompanying drawing the shuttle car cable drum that has long-range spacing control system of the present utility model is described in detail, wherein:
Fig. 1 is the circuit diagram that has the shuttle car cable drum of long-range spacing control system according to the utility model;
Fig. 2 is the side perspective scheme drawing of this cable drum.
The specific embodiment
See also Fig. 1 and Fig. 2, the foundation shuttle car cable drum 1 that has long-range spacing control system of the present utility model is used for the Coal Transport under the coal mine, it comprises control circuit PR, cable drum 40, be wrapped in the cable 44 on the cable drum 40, be located on this cable drum 40 and the reel switch of when described cable scatters fully, opening automatically 42, these reel switch 42 1 ends are connected with this control circuit PR, and the other end is in series with control relay RLC, this control relay RLC and control transformer CT coupling are to obtain suitable power supply, and described control relay RLC further is in series with line circuit breaker 20.
As depicted in figs. 1 and 2, when volume had cable 44 on this cable drum, cable 44 these reel switches 42 of compressing made its closure, the normal adhesive conducting of control relay RLC this moment, and make control circuit PR conducting realize normal running; And when cable 44 cleared on this cable drum 40, this reel switch 42 was opened, and control relay RLC outage this moment so that the power supply of control circuit PR is disconnected, thereby realizes emergency.Described reel switch 42 is the elastic force switch, promptly only just is kept closed under switch is subjected to the situation of suitable pressure.Certainly, those skilled in the art can understand, in order to guarantee that further timely power on/off is to realize safe construction, can dial the plate contact by adopting, reel revolution-meter control contact, modes such as sensor monitors control contact realize the function of above-mentioned on-off circuit, particularly, one additional detection means can further be set on cable drum 40, it comprises a revolution-meter (not shown) and one and line circuit breaker 20 series connected master cock (not shown), this counting machine is had the maximum rotating cycle of reel 40 in advance by cable 44 length settings, in application process, as long as the number of turns of reel 40 reaches maxim (no matter advance or retreat), master cock is a cut off, and when counting, the zero clearing of counting machine elder generation. next time
Described control relay RLC connects with line circuit breaker 20 by lead.When reel switch 42 closures, this control relay RLC energising, shuttle car normal operation; When this reel switch 42 is opened, this control relay RLC outage makes the entire circuit outage, to cut off the shuttle car power supply and it is stopped.
Among the above-mentioned control circuit PR, can further be provided with disconnection fault lamp (not shown), this disconnection fault lamp extinguishes when control circuit PR switches on, and lights when control circuit PR cuts off the power supply, and has cleared with the alert cable, can't move on.The those of ordinary skills that are configured to of described disconnection fault lamp understand, and do not give unnecessary details at this.
When using long-range spacing control system of the present utility model, at first closed line circuit breaker 20, move shuttle car then, when being wound with cable 44 on the cable reel 40, cable 44 compressing reel switches 42 closures, make the normal adhesive conducting of control relay RLC, realize normal running with turn-on control circuit PR; And when cable 44 clears on this cable drum 40, this reel switch 42 automatically springs open, make control relay RLC outage, to disconnect the power supply of control circuit PR, to cut off the shuttle car power supply it is stopped, preventing that the cable drum 42 that cable 44 is broken by force and caused from damaging the accident that reaches so cause, and guaranteed the ordinary production of shuttle car thereby finally reach, save the maintenance time that causes because of this fault, greatly reduced the maintenance cost of shuttle car.
