Moreover, non-ferrous metal used in the cable of the coal mining machine on the comprehensive mining surface can be saved, and raw materials and energy can be saved.
Description
Technical field
The utility model relates to coal-winning machine, relates in particular to a kind of transporter blocking device that is used for coal-winning machine.
Background technology
In coal-winning machine, need the device of transporter on the face that can in time quit work, i.e. the transporter blocking device.
At present, on the fully-mechanized mining working of mining area, employed some coal-winning machine has the transporter blocking device, as German AKF coal-winning machine and U.S. JOY coal-winning machine.But these transporter blocking devices all adopt six heart yearn cables 300, and an end of described six heart yearn cables connects coal-winning machine emergency stop switch 100, and the other end is controlled promptly stopping of scratch board conveyor 200 by two cores wherein.
Because the down-hole particular surroundings pulls the wearing and tearing that cable can cause cable, causes the instability of locking.So the energy that need aspect safeguarding, cost a lot of money, and then cause maintenance, the required labor intensive of maintenance to increase.
So, be necessary to design a kind of novel transporter blocking device that is used for coal-winning machine, to overcome the defective of prior art.
The utility model content
At the defective of prior art, the purpose of this utility model provides a kind of stable, simple in structure transporter blocking device of locking that is used for.
The transporter blocking device that is used for coal-winning machine that the utility model provides comprises coal-winning machine emergency stop switch, cable, coal-winning machine guide loop, transporter gauge tap, wherein, the coal-winning machine emergency stop switch is connected with coal-winning machine guide loop by cable, coal-winning machine guide loop is connected to the power loop contactor of coal-winning machine, and described power loop contactor is connected with the transporter gauge tap.
Preferably, the transporter gauge tap is a CHP33 type stacked switch.
Preferably, the transporter gauge tap is a KJZ/9 type stacked switch.
Preferably, the transporter gauge tap is a KJZ/14 type stacked switch.
Preferably, described cable is the four-core cable.
Preferably, the coal-winning machine emergency stop switch is a pullswitch.
With respect to prior art, the transporter blocking device in the utility model has improved the functional reliability of coal-winning machine locking transporter on the fully-mechanized mining working, and, saved the non-ferrous metal that cable consumed of coal-winning machine on the fully mechanized coal face, saved the raw material and the energy.
Description of drawings
Fig. 1 is the structural representation that is used for the transporter blocking device of coal-winning machine in the prior art
Fig. 2 is the structural representation that is used for the transporter blocking device of coal-winning machine of the present utility model.
The specific embodiment
The transporter blocking device that is used for coal-winning machine of a kind of specific embodiment of the utility model comprises coal-winning machine emergency stop switch 201, cable 202, coal-winning machine guide loop 203, transporter gauge tap 204, wherein, coal-winning machine emergency stop switch 201 is connected with coal-winning machine guide loop 203 by cable 202, coal-winning machine guide loop 203 is connected to the power loop contactor 205 of coal-winning machine, so that the power loop contactor 205 of control coal-winning machine, described coal-winning machine power loop contactor is connected with transporter gauge tap 204.
The coal-winning machine emergency stop switch is arranged on the coal-winning machine, can adopt various suitable switches to realize.In the specific embodiment of the present utility model, the coal-winning machine emergency stop switch is a pullswitch.
The transporter gauge tap is the crossheading stacked switch, and preferably, in the utility model, the transporter gauge tap is a CHP33 type stacked switch.The CHP33 stacked switch is Britain B﹠amp; The crossheading control switchgroup that F company produces.The CHP33 stacked switch is the transporter gauge tap of 3300V, can be used for controlling coal-winning machine and the scratch board conveyor of 3300V.Also have corresponding coal-winning machine loop contactor in the CHP33 stacked switch, be used for the electric or corresponding switch closure action of outage execution according to getting of coal-winning machine guide loop 203.
Selectively, the transporter gauge tap also can adopt KJZ/9 type stacked switch or the KJZ/14 type stacked switch that Changzhou Lian Li company produces.The utility model is applicable to all coal-winning machines that meet " safety regulations in coal mine " regulation, and preferably, the coal-winning machine that the utility model was suitable for is AKF type coal-winning machine and JOY type coal-winning machine.
In the utility model, owing to need not directly control transporter by coal-winning machine emergency stop switch 201, so cable can save two heart yearns, employing four-core cable.
After according to the technical solution of the utility model repacking, with two cores that saved in six core cables that connect the coal-winning machine emergency stop switch, coal-winning machine guide loop 203 is connected with transporter gauge tap 204, thereby has realized the coal-winning machine loop contactor → crossheading stacked switch scraper plate machine start and stop workflow that program → the scraper plate machine moves/stops by coal-winning machine emergency stop switch → coal-winning machine guide loop → crossheading stacked switch inside.When the coal-winning machine guide had electricity, the coal-winning machine contactor of transporter gauge tap 204 the insides will adhesive, and it is closed that described coal-winning machine contactor long made war, and transporter allows junction closure, and transporter just possesses the start condition, just can start shooting.If under open state, emergency takes place, operating personnel can operate the coal-winning machine emergency stop switch, coal-winning machine guide outage, the contactor outage in the coal machine loop of transporter gauge tap 204 the insides, the normal battle disconnects, and the virtual joints transporter allows to disconnect in the CHP33 stacked switch control program, makes transporter stop.
Although it will be understood by those skilled in the art that the utility model is to be described by above-mentioned preferred embodiment, its way of realization is not limited to above-mentioned embodiment.Should be realized that under the situation that does not break away from the utility model purport those skilled in the art can make different variations and modification to the utility model.
