Specific embodiment
The embodiment of the present application by providing a kind of prior-warning device of manual skate for high pedestal jib crane walking mechanism,
Walking motion but hand can occur after being connected to door machine walk signal for the walking mechanism for solving high pedestal jib crane in the prior art
The problem of dynamic skate is not extracted in traveling wheel also and manual skate is caused to be pressed realizes to seat type crane travelling gear
Manual skate early warning, avoid manual skate and pressed and make troubles to production.
In order to solve the above technical problems, the general thought that the embodiment of the present application provides technical solution is as follows:
The embodiment of the present application provides a kind of prior-warning device of manual skate 5 for high pedestal jib crane walking mechanism, institute
Stating device includes: traveling wheel 1；Movable motor 2, the movable motor 2 are connect with the traveling wheel 1, and the movable motor 2 drives
The traveling wheel 1 is walked；PLC travelling control unit 3, the PLC travelling control unit 3 are connect with the movable motor 2, control
The working condition of the movable motor 2；Travel switch 4, the travel switch 4 are electrically connected with the PLC travelling control unit 3,
The working condition of PLC travelling control unit 3 described in the folding control for forming switch；Manual skate 5, the manual skate 5
It is connect with the travel switch 4, the motion state of the manual skate 5 controls the folding of the travel switch 4.
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
Referring to Fig. 1 and Fig. 2, specifically, the traveling wheel 1 is mounted on high pedestal jib crane, when traveling wheel 1 is in orbit
When walking, drive entire high pedestal jib crane mobile, when traveling wheel 1 is static, high pedestal jib crane is fixed at its stopping, at this time
High pedestal jib crane can work normally.
The movable motor 2 is connected with the traveling wheel 1, the movable motor 2 be used to control the walking of traveling wheel 1 with
It stops.When movable motor 2 issues travel commands, traveling wheel 1 receives instruction and starts to walk；Stop when movable motor 2 issues
When instruction, traveling wheel 1 receives instruction and stops.
The PLC travelling control unit 3 is arranged in the electric panel room of high pedestal jib crane, and with 2 phase of movable motor
Connection.The second route, the PLC travelling control unit 3 are formed between the PLC travelling control unit 3 and the movable motor 2
When in running order, the working condition of the movable motor 2 is controlled by second route.It is controlled when the PLC walks
When unit 3 processed issues limitation travel commands, travel commands are limited by second route and pass to the movable motor 2, row
It walks motor 2 not work, traveling wheel 1 connected to it will not generate walking motion.
The travel switch 4 is electrically connected with the PLC travelling control unit 3, for controlling the PLC travelling control unit
3 disconnection and closure.First line is formed between the travel switch 4 and the PLC travelling control unit 3.The stroke is opened
When closing 4 closure, the PLC travelling control unit 3 is in running order, and the PLC travelling control unit 3 issues limitation row at this time
The instruction walked, the instruction for limiting walking pass to the movable motor 2 by second route, and movable motor 2 does not work, with
Its traveling wheel 1 connected will not generate walking motion.When the travel switch 4 disconnects, at the PLC travelling control unit 3
In off-state, the PLC travelling control unit 3 cannot work at this time, will not issue the instruction of limitation walking to the walking
Motor.If the movable motor 2 receives the instruction of door machine walking at this time, the movable motor 2 works, and controls and its phase
The traveling wheel 1 of connection is walked.
The manual skate 5 is connect with the travel switch 4, and the motion state of manual skate 5 controls the travel switch 4
Folding.The movable motor 2 receives the instruction of door machine walking, will start the traveling wheel 1 and walks, if described at this time manual
Skate 5 is under the traveling wheel 1, then traveling wheel 1 can encounter the manual skate 5, and the travel switch 4 perceives between the two
Displacement, to be in closed state, the first line is connected.If the movable motor 2 receives the instruction of door machine walking
And start the traveling wheel 1 and walk, manual skate 5 is not inserted under the traveling wheel 1, then will not trigger the travel switch 4, institute
It states first line and is still in off-state.High pedestal jib crane can normal walking.
The welding support 6 is fixed on the traveling wheel 1, and the travel switch 4 is fixed on the welding support 6
On.Since one end of the travel switch 4 is connected with described, the other end and the manual folding of skate 5 are connected, therefore using will
The travel switch 4 is fixed on the traveling wheel 1, and the travel switch 4 is enabled accurately to experience the traveling wheel 1 and hand
Displacement between dynamic skate 5 avoids the suspension of travel switch 4 from being easy to be touched and be closed in the sky, so that coupled PLC
There are the limitation travel commands of mistake in travelling control unit 3, to improve the accuracy and whole system of the closure of travel switch 4
Reliability.
Working principle: the movable motor 2 of high pedestal jib crane receives the instruction of door machine walking, will start the traveling wheel
1 walking.If manual skate 5 does not take out at this time, traveling wheel 1, which is walked forward, encounters manual skate 5, the row being fixed on traveling wheel 1
Cheng Kaiguan 4 experiences the displacement between traveling wheel 1 and manual skate 5, and triggering travel switch 4 is closed, at this point, first line connects
Logical, PLC travelling control unit 3 is in running order, issues the instruction of limitation walking, and instruction is transmitted to walking by the second route
On motor 2, movable motor 2 receives the instruction of limitation walking in idle state, and coupled traveling wheel 1 is therefore
It will not walk, push down manual skate 5 so as to avoid the walking of traveling wheel 1, realize traveling wheel 1 when not taking out to manual skate 5
Walking can push down the early warning of manual skate 5.
Due to controlling the folding of travel switch using whether manual skate is inserted into traveling wheel, so that control PLC is walked
Unit sending is forbidden or is not prohibited by the order of walking to control movable motor, to control whether traveling wheel walks, so effectively
It solves manual skate also to extract not in time in traveling wheel, walking mechanism also will continue to that walking motion occurs, so as to cause hand
The problem of dynamic skate is pressed, and then the early warning against pressure to the manual skate of seat type crane travelling gear is realized, it avoids
Manual skate is pressed to make troubles to production.
Provided with welding support, the travel switch 4 is fixed on the traveling wheel 1 by welding support, so that institute
Displacement between the traveling wheel 1 and manual skate 5 can accurately be experienced by stating travel switch 4, avoided travel switch 4 and be suspended on
It is easy PLC travelling control unit 3 caused by being touched closure in the air and issues mistake limitation travel commands, to improve stroke
The reliability of accuracy and whole system that switch 4 is closed.
Finally it should be noted that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although reference
Preferred embodiment describes the invention in detail, those skilled in the art should understand that, it can be to of the invention
Technical solution is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered
In scope of the presently claimed invention.
