Abstract
The utility model discloses an automatic detection device for a sling trolley, which is composed of brackets (5) on the lateral sides of the sling trolley, proximity switches and a proximity switch PLC trigger comparison device; the brackets (5) on both sides are arranged symmetrically, the brackets are groove-shaped, two proximity switches are arranged on each bracket and connected with each other in parallel, the proximity switches are arranged vertically, the space between the proximity switches is equal to the diameter of a roller wheel. The automatic detection device can automatically detect the damaged part, sends alarm in time and stops the product line, and accordingly reduces the loss to the minimum degree. The automatic detection device for the sling trolley has simple structure, low cost and is applicable to conveyer lines of auto industry and similar industries.
Description
Technical field
The utility model relates to a kind of pick-up unit, has especially proposed to relate to a kind of hoisting tool bogie roller automatic detection device.
Background technology
Car coating production line suspender is owing to move in the moistening pre-treatment cell body of high temperature for a long time, and the easy corrosion of its trolley idler wheels bearing damages, and causes the roller overcoat to come off.If the dolly that damages is in time found, in guide rail, move for a long time, stuck in cell body stretched wire track easily, operating difficulties during replacing, it is long to stop the line time.If adopt artificial spot check, that quantity that needs is many, and the time is long, and workload is big, and spot check frequency height is very loaded down with trivial details.Fault is stopped line and is caused the quality of lot accident to take place, and the vehicle body workpiece that collides with that falls in batch needs artificial grinding process, and serious directly scraps, thereby causes very big economic loss.Therefore be necessary to provide a kind of automatic detection device of real-time online.
Summary of the invention
The utility model has solved mainly in the production run that fault that chain jamming causes is stopped the line accident because of corrosion causes overcoat to come off because of the trolley idler wheels bearing, and a kind of easy automatic detection device is provided.
The technical scheme that its technical matters that solves the utility model adopts is: the hoisting tool bogie automatic detection device, form by the support that is positioned at the hoisting tool bogie outside with near switch, for comparing the type device near switch triggering PLC, described both sides support symmetric arrangement, support is a flute profile, two in parallel describedly vertically are provided with near switch near switch on each support, and spacing equals roller diameter.Roller when hoisting tool bogie arrives near the switch place like this, will issue a signal to PLC.If the revolver check point is put ON, the expression dolly, and the dolly revolver does not have disappearance.Same method, we detect right wheel with other signal, by comparing the time of arrival of two signals, judge whether hoisting tool bogie is working properly.
As preferably, a kind of hoisting tool bogie automatic detection device, described support are channel-section steel, and the channel-section steel bottom wing vertically is welded with the steel plate isometric with support, and roller places in the chamber of support and steel plate.Roller is subjected to the constraint of steel plate, and unlikely wandering off and running near switch reduced misoperation.
As preferably, a kind of hoisting tool bogie automatic detection device is stated near four on switch totally, be respectively upper left near switch, lower-left near switch, upper right near switch, bottom right near switch, after the parallel connection, connect two input ends of PLC respectively in twos.The upper and lower layout of homonymy be in parallel near switch, when roller arrives, only send a signal.The purpose that repeats to be provided with is in order to improve accuracy, and when one temporarily lost efficacy near switch, another still can in time send signal near switch.
The utility model has the advantages that simple in structure, cost is low, hoisting tool bogie is in when operation, and four provide two signals near switch.Signal send Central Control Room PLC, judges the dolly wheel situation by the PLC procedure identification.Produce the output of reporting to the police during fault, carry out sound and light alarm and stop chain, remind the maintenance personal to go to the detection scene to carry out balladeur train and change.Use such hoisting tool bogie automatic detection device, production efficiency, product quality are greatly improved, and have reduced enterprise cost simultaneously.

Embodiment
Be further described in detail below by embodiment and in conjunction with Fig. 1 to 5 pair of the technical solution of the utility model.
Embodiment 1: at the long 15# channel-section steel 5 following welding one block length 300mm of 300mm, wide 38.6mm, the steel plate 6 of thick 10mm, two diameters of processing are the 12mm hole on channel-section steel 5, and two electronic proximity switches are installed: upper left near switch 1 and lower-left near switch 2, parallel connection.Make the another side of pick-up unit of above same square.Two electronic proximity switches are installed: upper right near switch 3 and bottom right near switch 4, same in parallel.About two blocks of channel-section steels 5 be welded on the stretched wire carrying rail of hoisting tool bogie process, guarantee steel plate 6 spacings on left and right two limits, allowing hoisting tool bogie pass through, but and in the appropriate distance of inductive proximity switch.Establishment PLC automatic control program.Upper left be the revolver check point near switch 1 and lower-left near switch 2 electronic proximity switch signal definitions, PLC input point address is 12.07; Upper right is right wheel check point near switch 3 and bottom right near switch 4 electronic proximity switch signal definitions, and PLC input point address is 11.15.If revolver check point 12.07 is put ON, the expression dolly, and the dolly revolver do not have disappearance, and we detect right the wheel with this signal.Root a tree name chain speed and trundle diameter decision time are long, set 10 milliseconds, because the time that left and right sides two-wheeled arrives can not be simultaneously absolute, if right wheel has also come in 10 milliseconds, signal 11.15 is changed to ON, and then right wheel is normal.Otherwise if during this period, 11.15 is obstructed always, right wheel disappearance.If right side wheel check point 11.15 is put ON, the expression dolly, and the right no disappearance of taking turns of dolly, we detect revolver with this signal.If in 10 milliseconds, signal 12.07 is changed to ON, and then revolver is normal.Otherwise, the revolver disappearance.
Embodiment 2: a kind of hoisting tool bogie automatic detection device, form by the support that is positioned at the hoisting tool bogie outside with near switch, for comparing the type device near switch triggering PLC, described both sides support symmetric arrangement, support is a flute profile, two in parallel describedly vertically are provided with near switch near switch on each support, and spacing equals roller diameter.Roller when hoisting tool bogie arrives near the switch place like this, will issue a signal to PLC.If the revolver check point is put ON, the expression dolly, and the dolly revolver does not have disappearance.Same method, we detect right wheel with other signal, by comparing the time of arrival of two signals, judge whether hoisting tool bogie is working properly.Described support 5 is a channel-section steel, and the channel-section steel bottom wing vertically is welded with the steel plate 6 isometric with support, and roller places in the chamber of support and steel plate.Roller is subjected to the constraint of steel plate, and unlikely wandering off and running near switch reduced misoperation.Near totally four on switch, be respectively upper left near switch 1, lower-left near switch 2, upper right near switch 3, bottom right near switch 4, after the parallel connection, connect two input ends of PLC respectively in twos.The upper and lower layout of homonymy be in parallel near switch, when roller arrives, only send a signal.The purpose that repeats to be provided with is in order to improve accuracy, and when one temporarily lost efficacy near switch, another still can in time send signal near switch.
