Hydraulic hoist is in building-site Installation and Debugging process; the defencive function of electrical control system still can not drop into fully; especially in Installation and Debugging process to " control is many " project; need often carry out stretching motion at pump house manual operation oil cylinder of hydraulic headstock gear; need site observation oil cylinder athletic performance state simultaneously; usually need many people to cooperate in this case, and adopt the Walkie talkie contact, often delay of response and occur wrong easily and may cause security incident.
After putting into operation after " control is many " project hydraulic hoist Installation and Debugging are finished, often need operate or before flood, gate is checked trial run and got rid of glitch, the operations staff usually will observe between gate and machine room and work back and forth, two places are at a distance of rice up to a hundred, need many people associated working simultaneously, and get in touch with by Walkie talkie, very inconvenient.
[utility model content]
Based on this, be necessary to provide a kind of remotely-controlled hydraulic hoist of realizing.
A kind of hydraulic hoist that is used for the regulating gate keying comprises the Executive Module that regulating gate opens or cuts out.Described hydraulic hoist further comprises remote signal transmitter module and remote control signal receiving module, described remote signal transmitter module is wirelessly connected to described remote control signal receiving module, described remote control signal receiving module is connected to described Executive Module and the signal that will receive from described remote signal transmitter module is sent to described Executive Module, and described Executive Module is carried out corresponding instruction according to the signal that receives.
Preferably, described hydraulic hoist further comprises decoder module, described decoder module is connected to described remote control signal receiving module and described Executive Module, and described decoder module sends described Executive Module to after receiving signal that remote control signal receiving module received and signal being converted to corresponding instruction.
Preferably, described Executive Module comprises programmable logic controller, and described remote control signal receiving module comprises no source contact, and described no source contact inputs to described programmable logic controller by auxiliary reclay.
Preferably, described remote signal transmitter module and described remote control signal receiving module have built-in antenna.
Preferably, described remote control signal receiving module also can comprise passive antenna.
Because hydraulic hoist is provided with remote signal transmitter module and remote control signal receiving module, and adopt the wireless signal communication between remote signal transmitter module and the remote control signal receiving module, so make operating personnel under mobile status, come the action of regulating gate at any time by the remote signal transmitter module, thereby be implemented in the headstock gear Installation and Debugging process, monitor at any time in the water pump assembly shutdown process, operate while observe.
[description of drawings]
Fig. 1 is the schematic diagram of the utility model preferred embodiment hydraulic hoist.
Fig. 2 is the electrical control schematic diagram of the hydraulic hoist among Fig. 1.
[specific embodiment]
Describe better embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in fig. 1, preferred embodiment hydraulic hoist of the present utility model comprises remote signal transmitter module 10, remote control signal receiving module 20, decoder module 30 and Executive Module 40.By communicating wireless signals, cable connects between remote control signal receiving module 20, decoder module 30 and the Executive Module 40 between remote signal transmitter module 10 and the remote control signal receiving module 20.Remote control signal receiving module 20, decoder module 30 and Executive Module 40 can be arranged in the switch board of hydraulic hoist jointly, and remote signal transmitter module 10 then can send remote signal in distance remote control signal receiving module 20 certain distance scopes.
When using, remote signal transmitter module 10 sends out remote signal, and remote control signal receiving module 20 receives the remote signal of sending shown in the remote signal transmitter module 10 and sends decoder module 30 to and decodes.30 decoded instructions send Executive Module 40 to through decoder module, Executive Module 40 execution command pairing actions (promptly controlling hydraulic jack opens a certain gate or close a certain gate).
Hydraulic hoist is provided with " terrain is manual ", " terrain is automatic ", " Long-distance Control " three kinds of methods of operation are controlled hydraulic hoist.Under " terrain is manual " mode, carry out single-step operation at switch board, not by PLC (programmable logic controller) control, but realize that by conventional relay circuit electric motor starting, hydraulic pressure system construction in a systematic way pressure, electromagnetic valve commutate and then the keying of regulating gate; Under " terrain is automatic " mode, operate at switch board, but, realize the keying of electric motor starting, hydraulic pressure system construction in a systematic way pressure, electromagnetic valve commutation and then regulating gate according to the program of establishment by PLC control; Under " Long-distance Control " mode, centralized control room sends the open and close door instruction to each gate terrain switch board in the distance, and terrain switch board follow procedure after receiving control instruction far away carries out the open and close door operation to gate.Operate by " Long-distance Control ", " terrain is automatic ", " terrain is manual " three kinds of modes; switch the oil pump selector switch and can under different conditions, carry out start and stop control, monitoring and protection Oil pump electrical machinery; automatically/remote control process in; during the list pump operation; when control system detects the main pump fault, autotomy and change to stand by pump operation and warning.
Under " terrain is automatic " mode, set up " long distance remote control " mode, in the advantage that guarantees to utilize under the cylinder action reliable premise remote control mode, make operating personnel under mobile status, control the action of hydraulic jack at any time, thereby be implemented in the headstock gear Installation and Debugging process, monitor at any time in the water pump assembly shutdown process, operate while observe.
To be the electrical control system that example illustrates this hydraulic hoist below with four hole Service gates.Corresponding to four gate holes, this hydraulic hoist comprises four hydraulic jacks and electrical control cabinet, and four hydraulic jacks are connected with four fan brake doors respectively, and each hydraulic jack opens and closes a fan brake door.As shown in Figure 2, YK1, YK2, YK3, YK4, YK5, YK6, YK7, YK8 are the no source contact of remote control signal receiving module 20 among the figure, input to PLC by auxiliary reclay.
Remote signal transmitter module 10 and remote control signal receiving module 20 all can adopt built-in antenna.In other optional embodiment, remote control signal receiving module also can install passive antenna additional separately, to strengthen the reception of remote signal.
Because of adopting the remote signal communication between remote signal transmitter module 10 and the remote control signal receiving module 20, so make operating personnel under mobile status, come the action of regulating gate at any time by remote signal transmitter module 10, thereby be implemented in the headstock gear Installation and Debugging process, monitor at any time in the water pump assembly shutdown process, operate while observe.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
