Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Please refer to Fig. 2, Fig. 2 is the circuit connecting relation schematic diagram of the utility model pull switch system.
A kind of pull switch system, comprising:
Voltage source 3, loop end 4 and detection port 5;
Multiple pull switch assembly 2, described multiple pull switch assembly 2 is connected, and described pull switch assembly 2 comprises:
Pull switch, described pull switch comprises the open contact 202 and normally closed contact 201 that can mutually switch, described normally closed contact 201 is arranged between described voltage source 3 and described loop end 4, and described open contact 202 is arranged between described voltage source 3 and detection port 5;
Resistance 203, described resistance 203 is arranged between described open contact 202 and described detection port 5;
Detector, described detector is connected with described detection port 5, for determining described stay cord protection cable whether fault and trouble point according to the magnitude of voltage of described detection port 5.
Described pull switch assembly 2 also comprises open circuit detector switch 204, and one end of described open circuit detector switch 204 is connected with voltage source and the other end is connected with described pull switch.
Described normally closed contact 201 place is provided with tension spring, also arrange between described open contact 202 and described normally closed contact 201 allow switch between described normally closed contact 201 and described open contact 202 pull parts, described in pull parts one end pass described pull switch assembly 2.
Described pull switch assembly 2 also comprises relay indicating light 205, described relay indicating light 205 is arranged between described open circuit detector switch 204 and described pull switch, when open contact 202 or normally closed contact have the conducting of any one end, then relay indicating light 205 is bright, represents that open circuit does not occur the circuit between voltage source 3 to this pull switch assembly 2.
The general length of the travelling apron of convey materials, ore used for stope longer (generally more than 1 kilometer), therefore needs to adopt more piece assembling mechanism to assemble.Travelling apron is except end points place is provided with voltage source 3, loop end 4 and detection port 5, also comprise more piece assembling mechanism, more piece assembling mechanism is except being mechanically connected, often save assembling mechanism inside to be provided with pull switch assembly 2 and to connect for circuit, pull switch assembly 2 comprises pull switch, and pull switch comprises the open contact 202 that can mutually switch and normally closed contact 201, the resistance 203 of fixed resistance value and the open circuit detector switch 204 for detecting the whether open circuit of circuit between pull switch assembly 2 and voltage source.
Suppose that the magnitude of voltage of voltage source 3 is 24V, under normal condition, (all assembling mechanism mechanical connections are connected all normal with circuit, normally closed contact 201 is in closure state, open contact 202 is in off-state, open circuit detector switch 204 is in off-state), the magnitude of voltage that loop end 4 detects is about 24V.
When travelling apron is after moving integrally, when loop end 4 detects and finds open circuit, may be the pull switch action (normally closed contact 201 of the pull switch of this assembling mechanism disconnects, and open contact 202 closes) of certain package assembly,
When loop end 4 do not have voltage and detection port 5 detect magnitude of voltage be some be less than the particular value of 24V time, because each pull switch assembly 2 is provided with the resistance 203 of fixed resistance value, (resistance 203 can be arranged according to shown in Fig. 2, also open contact 202 rear can be arranged on), by the magnitude of voltage that detection port 5 detects, travelling apron Circuits System can be derived additionally to have connected the resistance 203 of how many resistances, thus determine which pull switch action (as counted from voltage source 3 end, 2nd assembling mechanism pull switch action), corresponding pull switch recovers by workstation Personnel Appointment staff, when detecting detection port 5, also can't detect voltage (i.e. Circuits System open circuit), staff can close the open circuit detector switch 204 of this assembling mechanism one by one from voltage source 3 one end, the magnitude of voltage at measure loop end 4 and detection port 5 place respectively, judge the circuit whether open circuit of voltage source 3 one end to this assembling mechanism, whether can be lighted by power detecting indicator lamp 205 simultaneously and see that whether pull switch assembly 2 internal circuit is working properly on the spot.Adopt the occurrence positions detecting travelling apron fault in moving process that above-mentioned pull switch system can be very fast, on-call maintenance, debugging or change this assembling mechanism, thus improve mining efficiency.
Pull switch controls the handoff procedure of open contact 202 and normally closed contact 201: time under normal working, by spring thrust, normally closed contact 201 place conducting strip ensures that conducting strip contacts with normally closed contact 201; When being applied to the application force pulling parts and being greater than thrust spring application force, pull parts and conducting strip is moved to open contact 202 from normally closed contact 201, realize switching over.
Above-described embodiment is only for clearly illustrating that the utility model creates example, and not the utility model is created to the restriction of detailed description of the invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All within spirit of the present utility model and principle any apparent change of extending out or variation be still in the utility model and create among the protection domain of claim.
