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 illustrated in fig. 1 and 2, the same fine motion across overhead traveling crane of the present utility model is micro-stops formula collision avoidance system, normally closed photoelectric switch 300 and normally closed travel switch 200 is respectively arranged with in the sides adjacent of two carts, a pair normally closed contact of photoelectric switch 300 is serially connected in the quick input control loop of the remote controller 1 of corresponding cart respectively, travel switch 200 is serially connected in the advance input control loop of the remote controller of corresponding cart respectively, described quick input control loop and advance input control loop are also respectively arranged with the relay of the frequency converter input that can control corresponding cart, specifically, described quick input control loop and advance input control loop also arrange control coil respectively, the control inputs circuit of the frequency converter of the cart of correspondence is serially connected with open contact accordingly that mate with described control coil, namely on quick input control loop, control coil H-K03 is serially connected with, often open No. 5 for a pair corresponding with this control coil H-K03 and No. 9 pin points are serially connected between the very fast instruction input port S5 of control end SC and frequency converter 2, advance input control loop is serially connected with control coil H-K02, often open No. 5 for a pair corresponding with this control coil H-K02 and No. 9 pin points are serially connected between the advancement commands input port S2 of control end SC and frequency converter 2, the retrogressing input control loop of described remote controller is serially connected with normally closed limit travel switch 100, retrogressing input control loop is serially connected with control coil H-K01, often open No. 5 for a pair corresponding with this control coil H-K01 and No. 9 pin points are serially connected between the retrogressing instruction input port S1 of control end SC and frequency converter 2, on retrogressing input control loop and advance input control loop, be provided with interlock relay simultaneously, namely corresponding with control coil H-K01 and control coil H-K02 a pair normally closed contact 4 and 12 is serially connected in the control loop of another control coil respectively.Wherein, the operating distance of described photoelectric switch is greater than the operating distance of described travel switch.The operating distance scope of photoelectric switch is at 2-5m, and generally at more than 3m, the operating distance scope of travel switch, at 20-40cm, can realize the close as far as possible collision free again of two carts like this.
It should be noted that, because with comprising two carts across overhead traveling crane, the advance mentioned in the utility model literary composition refers to the direction that two carts are mutually close, namely, the cart in left side advances and refers to the right, and the cart on right side advances and refers to left, same retreat refer to two carts away from direction, namely the cart advance in left side refers to left, and the cart on right side advances and refers to the right.
When remote controller 1 exports slow astern (namely retreating), when advance at a slow speed (namely advancing) or very fast instruction, corresponding control loop can obtain electric signal, when two carts reach more far away operating distance, travel switch 200 and photoelectric switch 300 switch close and make to form loop with N, corresponding instruction exports the control coil H-K01 of then corresponding driving relay, H-K02 or H-K03 obtains electric, to make war accordingly when control coil obtains electric change close point, close point becomes makes war, such as when not reaching Limit States remote controller 1 and exporting retrogressing instruction, control coil H-K01 obtains electric, 4 and No. 12 pin points of H-K01 are often opened by normally closed change, its 5 and No. 9 pin points become normally closed by often opening.When 5 and No. 9 pin points close, control end Sc connects with retrogressing instruction input port S1, frequency converter obtains signal slow astern, now often open because 4 and No. 12 pin points of travel switch H-K01 have become, so even if progress signal at a slow speed given again by remote controller, that H-K02 coil can not be driven to obtain is electric, then S2 now can not obtain electric, can effectively avoid S1 and S2 simultaneously the frequency converter failure that causes of electric meeting, realize interlock function.Now remote controller exports very fast instruction, then control coil H-K03 obtains electric, and then very fast instruction input port S3 obtains electric, and from becoming at a slow speed fast after frequency converter obtains signal, direction remains unchanged, if very fast instruction input port S3 obtains electric separately, and frequency converter no-output.
When two large spacings near and when reaching the detection-sensitive distance of photoelectric switch, the normally closed contact of photoelectric switch disconnects, control coil H-K03 dead electricity, the now equal dead electricity of quick input port S3 of two carts, if then cart fast, becomes at a slow speed previously, if cart is originally static or at a slow speed, then hold mode is constant, if two large spacings are close further, reach the detection-sensitive distance of travel switch, travel switch normally closed contact disconnects, the now equal dead electricity of advance input port S2 of two carts, frequency converter no-output, now two carts can not be all quick, if cart first at a slow speed, becomes stopping, if cart is originally static, then hold mode is constant, now two carts opposing motion can only recover repertoire when reaching certain distance, when overhead traveling crane is to opposing direction, namely walking is retreated, when going to end position, travel switch 200 action, overhead traveling crane stop motion.
The utility model is based on the dual-speed control of large vehicle walking, cart introduces photoelectric switch and travel switch simultaneously, when running at high speed across overhead traveling crane together, photoelectric functional first plays brake deceleration effect when reaching predeterminable range, overhead traveling crane is at a high speed reduced to low speed, and when low speed, overhead traveling crane is reached by travel switch function and closely stops, and realizes that fine motion is micro-to stop, effectively overcome the indefinite difficult problem of stopping distance that in prior art, inertia and speed are brought, achieve more perfect safe operation.
Further, also comprise described photoelectric switch and travel switch box body accommodated therein, two switch designs are integrated, further simplify the convenience installed and arrange, wherein, described photoelectric switch is reflective photoelectric switch, and described travel switch is contact-type touch lever type travel switch.
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.
