Accompanying drawing explanation
Figure 1 shows that the circuit diagram with the overhead traveling crane of Remote Control Automatic reset function of the present utility model;
Figure 2 shows that the structural representation of remote controller.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, the overhead traveling crane with Remote Control Automatic reset function of the present utility model comprises the remote controller 10 with locking button 11 and release button 12, mate with described remote controller 10 and arrange and remote command described in receiving and by the receptor 20 controlling power supply energy supply, the control relay (not shown) that be connected controlled with described receptor, control relay can be one or more multiple-contact relay to provide multipair contact, wherein, indication normally closed and often open the state of contact when all referring to that the release button of remote controller is pressed in the utility model, when lock button or urgency described below stop button be pressed time, can state variation be there is in corresponding contact.During the multipair unlatching of described control relay, the first normally closed contact 21 is serially connected in cart advancement commands respectively one by one, cart retreats instruction, the instruction of dolly left lateral, the instruction of dolly right lateral, hoists on the signal wire (SW) of instruction and decline instruction; Second contact 22 of often opening through a pair unlatching of described control relay between the first contact 21-1 of the signal wire (SW) of the described instruction that hoists and the normally closed contact 31 of the limit position sensor that hoists is communicated to control power supply, the first contact 21-2 of the signal wire (SW) of described dolly left lateral instruction or the instruction of dolly right lateral and be communicated to control power supply through the 3rd open contact 23 chain with the normally closed contact of the limit position sensor that hoists and the second contact 22 with between the normally closed contact 32 of corresponding dolly left lateral or dolly right lateral limit position sensor; The 4th open contact 24 that between the normally closed contact 33 that the first contact 21-3 that described cart advancement commands or cart retreat the signal wire (SW) of instruction advances with corresponding cart or cart retreats limit position sensor, the normally closed contact of warp and corresponding dolly left lateral or dolly right lateral limit position sensor is chain and the second contact 22 are communicated to control power supply.
Wherein, described chainly a pair open contact corresponding with the normally closed contact of the limit position sensor of up or dolly left lateral or dolly right lateral is adopted to realize, while the normally closed contact state on the signal wire (SW) being serially connected in corresponding instruction changes, this chain open contact synchronous change state, realizes chain unlatching.That is, the multiple contact output by limit position sensor realizes chain.Namely chainly often to open, normally closedly refer to that same relay has two groups of contacts, be respectively often open, normally closed, its state is whole negate when coil obtains electric, and namely often open and become normally closed, normally closed change is often opened, and two groups of contacts can not be closed simultaneously or open simultaneously.
Overhead traveling crane of the present utility model, by the remote-controlled locking overhead traveling crane of remote controller, the all operations of shielding front-end control while locking overhead traveling crane, then control overhead traveling crane and automatically return to default end position, specifically, first, when pressing locking button, receptor receives remote signal and controls control relay action, then each first contact forwards off-state to by closed, the all operations of such front-end control is disconnected, simultaneously, second contact forwards closed to by off-state, the signal wire (SW) of instruction of hoisting is connected to control power supply, perform part, as contactless coil and frequency converter signal dry contact can receive the signal that hoists, namely control dolly and carry out hoisting action, when rise be raised to end position time, hoist limit position sensor normally closed contact disconnect, disconnect the connection controlling power supply and electric component, stop hoisting action, three contact chain with the normally closed contact of the limit position sensor that hoists forwards closed to by off-state simultaneously, then dolly right lateral (is described for dolly right lateral below, different according to the position of presetting, also can select dolly left lateral) signal wire (SW) of instruction with control power connection, then electric component continues to receive the instruction of dolly right lateral, when right lateral is to end position, the normally closed contact of right lateral limit position sensor disconnects, disconnect the connection controlling power supply and electric component, dolly stops right lateral, 3rd contact forwards closed to by off-state simultaneously, then, cart retreats and (is described for cart advance below, different according to the position of presetting, greater plantain also can be selected to enter) signal wire (SW) of instruction is communicated with control power supply, then electric component continues to receive cart advancement commands and action, when reaching cart and retreating end position, the normally closed contact that cart retreats limit position sensor disconnects, disconnect electric component and the connection controlling power supply, stop action, overhead traveling crane can be rested in default position automatically and lock.Because now the first contact of front-end control remains open state, can all operations be shielded, effectively realize using supervision.And rest in desired location, it also avoid to other inconvenience brought of constructing.
When needs unlock, press release button, then the first contact keeps normally closed, and the second contact remains open, and keeps and the off-state controlling power supply by the 3rd contact and the 4th contact, like this can normal running overhead traveling crane.
Further, for prevent from automatically returning to default position process in meet accident, described remote controller also comprises and suddenly stops button 13, the signal wire (SW) of described stop command is provided with a pair normally closed contact 4 of control relay, when depressed, electric component receives stop command, can stop action.
Preferably, for ease of instruction, also comprise and be arranged in parallel and be connected with described control power supply respectively and form red indicating light 5 and the green indicating lamp 6 in loop, described red indicating light with the circuit of green indicating lamp are respectively arranged with opening for a pair of being communicated with described control relay the 5th contact that state often opens and open the 6th normally closed contact of state, wherein red indicating light and green indicating lamp are arranged on the housing of electric cabinet.Carry out indicator lamp instruction in unlatching or lock-in state, effectively can improve human-computer interaction.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
