Description
Technical field
The utility model relates to field of garbage disposal, particularly trash compactor security protection system
Background technology
In order to reduce the floor space of rubbish, usually use vertical-type compressor that garbage truck is become block.Vertical-type compressor comprises dustbin, compressing mechanism and hydraulic system.Usual compressing mechanism is fixed on above dustbin, and dustbin is placed in melt pit.Four corners of dustbin are provided with column, and dustbin can rise along column or decline.Batch turning each time, the complete staff of entrucking can clean the rubbish that compression box is scattered, when also having maintenance repair and equipment cleaning, staff also needs to enter work in pond, casing hole, if now perform the rise of compression box and decline will be abnormally dangerous, easily causes casualties.In order to ensure the personal safety of staff, generally all safety pin can be inserted in the safety vent of dustbin side column, compression box is locked in certain position.But staff completes to overhaul and easily forget after equipment cleaning and is extracted by safety pin, and rise or down maneuver if now perform dustbin, the stop due to safety pin easily causes device damage and other danger.For the consideration of personnel and device security, vertical-type trash compactor installs security protection system and is necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of trash compactor security protection system protecting personnel and device security.
For achieving the above object, the utility model have employed following technical scheme: a kind of trash compactor security protection system, comprise and whether insert the sensor of column safety vent and the driver element for driving dustbin to be elevated for gathering safety pin, described sensor is by the Signal transmissions that collects to controller, and the output signal of controller controls driver element break-make.
Owing to adopting above technical scheme, insert in safety vent once controller collects safety pin, controller will cut off driver element, namely cut off the power source of dustbin, dustbin is avoided to rise when there being safety pin to insert or decline, effectively prevent the damage of equipment, improve the security performance of equipment.
Accompanying drawing explanation
Fig. 1 is FB(flow block) of the present utility model;
Fig. 2 is control circuit figure of the present utility model;
Fig. 3 is structural representation of the present utility model.
Detailed description of the invention
A kind of trash compactor security protection system, comprise and whether insert the sensor 10 of column safety vent and the driver element 30 for driving dustbin to be elevated for gathering safety pin, described sensor 10 is by the Signal transmissions that collects to controller 20, and the output signal of controller 20 controls driver element 30 break-make.Once controller 20 collects the signal in safety pin insertion safety vent, controller 20 will cut off driver element 30, namely cut off the power source of dustbin, dustbin is effectively avoided to rise when there being safety pin to insert or decline, prevent maloperation damage equipment, improve the security performance of equipment.
Trash compactor is arranged in garbage house 40, the side of garbage house 40 is provided with only for the transhipment mouth 42 of garbage truck turnover, opposite side is provided with the safety door 41 for personnel's turnover, the side of described safety door 41 is provided with the second sensor 50, second sensor 50 for gathering safety door 41 opening signal by the Signal transmissions that collects to controller 20.Generally be placed in tetragonal garbage house 40 by trash compactor, a side wall of garbage house 40 offers the passage for garbage truck turnover, is usually referred to as by this passage to transport mouth 42.The metope relative with transhipment mouth 42 arranges safety door 41, and personnel only to enter garbage house 40 from safety door 41, but can not enter from transhipment mouth 42.Due to trash compactor normally work time, compressing head needs movable, there is very large potential safety hazard, so be do not allow personnel to enter garbage house 40 when trash compactor works.When only having by the time trash compactor to quit work, personnel just can enter.In the utility model, arrange the second sensor 50 at the side of safety door 41, once the second sensor 50 collects the opening signal of safety door 41, controller 20 will cut off driver element 30, and trash compactor is quit work.Only restart driver element 30, trash compactor just can work on, and this system can effectively prevent personnel to be strayed into garbage house, protects, reduce potential safety hazard further to personal safety.
Described sensor 10 is for being fixed on the proximity switch of column safety vent side; Second sensor 50 opens proximity switch on path for being arranged on safety door, and the proximity switch in the utility model selects positive-negative-positive proximity switch.
Four corners of dustbin are respectively equipped with column, and the side of four column safety vents is provided with proximity switch.At present; dustbin is generally square; its four corners arrange a root post respectively; each root post is equipped with safety vent; the utility model arranges proximity switch on each safety vent side, dustbin action when avoiding safety pin not take, and is the equal of quadruple protection; to drop to minimum by carelessness and the unexpected probability caused casualties, the security performance of further raising equipment.
Described controller 20 is PLC.Described driver element 30 comprises for driving the hydraulic system 33 of dustbin action and for driving the pump motor 31 of hydraulic pump, and described controller 20 is connected with pump motor 31 by relay 32.
As Fig. 2, described relay 32 is open type AC relay.The coil pin 8 of relay 32 is connected with 380V three phase mains N line, its coil pin 7 is connected with the output of controller 20, its contact pin 1,3,5 is connected with 380V AC power L1, L2, L3 line respectively, and its contact pin 2,4,6 is connected with U, V, W line exchanging Electric Machine at Pumping Station respectively.
By reference to the accompanying drawings 2 and 3, specific works process is as follows:
One section of security protection control program is write in controller 20, open general supply, if safety door 41 is closed, safety pin 11, 12, 13 and 14 all do not insert around in four column safety vents, then proximity switch 1, 2, 3, 4 pin of 4 and 5 all export without 24V+ signal, then five inputs of controller 20 all input without 24V+ signal, the output of this Time Controller 20 exports alternating current 220V signal, the coil pin 7 input AC 220V signal of relay 32, then the coil of relay 32 obtains electric, contact pin 1 and the contact pin 2 of relay 32 are connected, contact pin 3 and contact pin 4 are connected, contact pin 5 and contact pin 6 are connected, then pump motor 31 obtains electric, normal rotation, trash compactor normally works.
Garbage house or safety pin 11 is entered when personnel open safety door 41, 12, 13 and 14 when at least inserting in a column safety vent, so proximity switch 1, 2, 3, 4 pin of 4 and 5 have at least a 24V+ signal to export, the then the rarest 24V+ signal input of five inputs of controller 20, the input signal locking of controller 20, the output of this Time Controller 20 exports without alternating current 220V signal, the coil pin 7 of relay 60 inputs without alternating current 220V signal, then relay 60 coil must not be electric, contact pin 1 and the contact pin 2 of relay 60 disconnect, contact pin 3 and contact pin 4 disconnect, contact pin 5 and contact pin 6 disconnect, then pump motor 32 power-off, stop operating, input that hydraulic system is unpowered, garbage-compressing machine equipment quits work.
Even if in said process, safety door 41 opens rear closedown, safety pin 11,12,13 and 14 is all extracted from column safety vent, controller 20 also can cut off driver element 30, the i.e. coil pin 7 no signal input of relay 60, relay 60 coil must not be electric, contact pin 1 and the contact pin 2 of relay 60 disconnect, contact pin 3 disconnects with contact pin 4, contact pin 5 disconnects with contact pin 6, pump motor 31 power-off, stops operating.Must restart general supply (restarting after controller 20 power-off), the disabler of signal locking, garbage-compressing station equipment normally works.Security protection system in the utility model serves good protective action, greatly reduces unexpected odds, ensure that the safety of personnel and equipment.
