According to the equipment, command and liaison time in an original production mode is eliminated, the crane inching in-place operating frequency is reduced, the lifting cycle time of the equipment is shortened, the labor productivity is improved, the service life of the equipment is prolonged, and the cost of operators is reduced.

Description

The two remote controller control devices of a kind of hoisting crane

Technical field

The utility model belongs to technical field of automatic control, relates to the two remote controller control devices of a kind of hoisting crane.

Background technology

Hoisting crane has a very wide range of applications in iron and steel enterprise, owing to being that steel product is produced line and storehouse is all the long span of hundreds of rice conventionally, mode of operation is generally driver's cab operation, and every hoisting crane need configure 4 operating personnels, comprises that 1 crane driver, 2 extensions refer to work, 1 tally work.Extension refers to that work is responsible for hanging fortune equipment, and be responsible for getting in touch with commander with operative employee, operative employee is responsible for operating and drives a vehicle, tally work is responsible for Inspection equipment quality, is carried out the record of data.Crane operation work is in driver's cab, can not accurately see distance between equipment and on-station position clearly, equipment is in place mainly refers to work commander by extension, for the sake of security, when equipment is in place, operative employee can take repeatedly slowly installation method of crawl, hangs and refers to that between work and operative employee, contact can take the more time.When extension refers to that work is hung fortune equipment, operative employee is in wait state, during driving operation, hangs and refers to that work is in wait state, when equipment is in place, hangs and refers to that work and operative employee in fact still do something simultaneously.So under this traditional work pattern, labor productivity is very low.

Utility model content

In order to address the above problem, the utility model provides a kind of hoisting crane two remote controller control devices.

The utility model solves the technical scheme that its technical matters adopts:

The two remote controller control devices of this hoisting crane comprise hoisting crane PLC, 1# remote controller projector, 1# remote controller receiver, 2# remote controller projector, 2# remote controller receiver; 1# remote controller projector is connected by wireless mode with 1# remote controller receiver; 2# remote controller projector is connected by wireless mode with 2# remote controller receiver; 1# remote controller launcher signal can only be received by 1# remote controller receiver, and 2# remote controller launcher signal can only be received by 2# remote controller receiver; 1# remote controller receiver, 2# remote controller receiver are connected with hoisting crane PLC.Two remote controller projectors all arrange a control authority select switch, and when 1# side is in " releasing authority " state, 2# side is when " work authority " state, and 2# remote controller, by obtaining the operating right of hoisting crane, can be realized the control to hoisting crane; When 2# side is in " releasing authority " state, 1# side is when " work authority " state, and 1# remote controller, by obtaining the operating right of hoisting crane, can be realized the control to hoisting crane.And under other states, two remote controllers will all cannot be controlled hoisting crane, hoisting crane is also standby simultaneously, will can not move.

Operating process is, two extensions refer to that work is responsible for the operation of remote controller, two ends in hoisting crane work region respectively, when hoisting crane is during near the operation of 1# side, the extension of 2# side refers to that work chooses its remote controller " releasing authority " position, and the extension of 1# side refers to that work chooses its remote controller " work authority " position, at this moment 2# remote controller is the remote manipulation discharging hoisting crane, and 1# remote controller is taken over the remote manipulation to hoisting crane.Otherwise, if hoisting crane is during near the operation of 2# side, the extension of 1# side refers to that work chooses its remote controller " releasing authority " position, and referring to work, the extension of 2# side its remote controller is chosen to " work authority " position, at this moment 1# remote controller remote manipulation to hoisting crane by release, and 2# remote controller is taken over the remote manipulation to hoisting crane.

The beneficial effects of the utility model are after adopting the utility model, only need 2 extensions to refer to work hold concurrently remote controller, 1 tally work, extension refers to that work is at terrestrial operation hoisting crane, the commander who has eliminated under original production pattern gets in touch with the time, reduce hoisting crane crawl number of operations in place, compressed equipment handling period, improved labor efficiency, extend equipment life, also reduced personnel cost simultaneously.

The specific embodiment

Below in conjunction with technical scheme and accompanying drawing, describe specific embodiment of the utility model in detail.

Embodiment:

System of the present utility model forms as shown in Figure 1,1# remote controller projector B and 1# remote controller receiver C pairing are used, 2# remote controller projector D and 1# remote controller receiver E pairing are used, these two pairs of remote controllers are independent mutually, 1# remote controller launcher signal can only be received by 1# remote controller receiver, and 2# remote controller launcher signal can only be received by 2# remote controller receiver.1# remote controller receiver and 2# remote controller receiver are passed to the signal of its acceptance respectively hoisting crane PLC A, by hoisting crane PLC more respectively according to the run action of signal control hoisting crane.The switching of two remote controllers as shown in Figure 2 circuit completes.Wherein L+ and M are 24V direct supplys.K11 is from 1# remote controller receiver, represents the serviceability of 1# remote controller, and K11 adhesive represents that 1# remote controller is in " work authority " position, and K11 during adhesive, does not represent " releasing authority " position.K21 is from 2# remote controller receiver, represents the serviceability of 2# remote controller, and K21 adhesive represents that 2# remote controller is in " work authority " position, and K21 during adhesive, does not represent " releasing authority " position.K001 is 1# remote controller mode of operation relay, and this relay, only in K11 adhesive and K21 could adhesive during adhesive, represents that 1# remote controller has control, otherwise represents that 1# remote controller does not have control.K002 is 2# remote controller mode of operation relay, and this relay, only in K21 adhesive and K11 could adhesive during adhesive, represents that 2# remote controller has control, otherwise represents that 2# remote controller does not have control.K003 is alarm relay, represents 1#, 2# remote controller condition selecting mistake when this relay adhesive, two remote controllers may be all in " work authority " position, or two remote controllers are all in " releasing authority " position, and at this moment K003 adhesive is reported to the police, and hoisting crane is by out of service.K001, K002, K003 input at hoisting crane PLC, by PLC, according to the state of these three relays, selected by 1# or 2# remote controller, hoisting crane to be controlled again, during if there is wrong (being K003 adhesive), stop immediately the operation of hoisting crane, guarantee system safety operation.
