Abstract
The utility model relates to a straightening machine especially relates to a straightening machine with safe round pin cuts off automatic checkout device. The utility model discloses a set up safe round pin on the drive machine output shaft, set up detecting element at the reducing gear box output, can effectual automation judge whether the straightening machine cuts off at aligning in -process safety round pin, and the protectiveness of carrying on of automation is parkked then, in time avoids because the equipment that this trouble caused damages and other troubles. Whole process is full -automatic judgement, does not need artificial reaction and affirmation, and the operation more reliable for the straightening machine provides the sound assurance.
Description
Technical field
The utility model relates to straightener, especially relates to a kind of straightener cutting off automatic detection device with safety pin.
Background technology
Slab straightener be a kind of to the steel plate after rolling by two row working rolls the smooth equipment of secondary is carried out to steel plate; its layout type is the secondary distribution of nine working rolls (two row's distributions) by distributor; dragged by two powerful ac variable-frequency electric motors; in order to more effective protection driving motor; a safety pin is installed between motor and power transmission shaft; when shaft torque reaches the setting value of safety pin, safety pin cuts off automatically.In equipment real-world operation process; smoothing roll is when aligning steel plate; once occur that the excessive or roll gap of straightening force arranges mistake; just there will be driving torque excessive, safety pin will protectiveness cut off, and now control system cannot effectively judge; straightener continues to carry out straightening work with former roll gap; cause steel plate also in straightener, originally by the steel plate of two driven by motor due to the cut-out of a wherein safety pin, cause and only have a motor to drive.If operating personnel cannot Timeliness coverage, the more serious faults such as device damage are just easily caused to occur.
Utility model content
In order to solve the problems of the technologies described above, the straightener cutting off automatic detection device with safety pin that the utility model provides a kind of security high.
The technical solution adopted in the utility model is: a kind of straightener cutting off automatic detection device with safety pin, comprise the first driving motor, the second driving motor, distributor and smoothing roll, described first driving motor passes through the first power transmission shaft through smoothing roll described in described distributor rear drive, described second driving motor by second driving shaft through smoothing roll described in described distributor rear drive, it is characterized in that: described first power transmission shaft is provided with the first safety pin, dispenser output end is provided with first detecting element corresponding with the first safety pin; Described second driving shaft is provided with the second safety pin, dispenser output end is provided with second detecting element corresponding with the second safety pin.
As preferably, described first detecting element and the second detecting element are controlled automatically by PLC.
As preferably, described first detecting element is for detecting the shutoff signal of the first safety pin; Described second detecting element is for detecting the shutoff signal of the second safety pin.
As preferably, described first detecting element and the second detecting element are proximity switch.
The beneficial effect that the utility model obtains is: of the present utility model by arranging safety pin on driving motor output shaft; at reduction box output, detecting element is set; can effectively whether cut off by automatic decision straightener safety pin in straightening process; then carry out protectiveness parking automatically, avoid the device damage because this fault causes and other faults in time.Whole process is full-automatic judgement, does not need artificial reaction and confirmation, provides sound assurance for straightener runs more reliably.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is control principle drawing of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, a kind of straightener cutting off automatic detection device with safety pin of the present utility model, comprise the first driving motor 1, second driving motor 2, distributor 7 and nine smoothing rolls 10, wherein the first driving motor 1 by the first power transmission shaft 3 through gearbox and the first five root smoothing roll of distributor 7 rear drive (above 2,3 below), second driving motor 2 is by second driving shaft 4 four smoothing rolls (above 2, below 2) after gearbox and distributor 7 rear drive.
In order to protect mair motor and gearbox, first driving motor 1 with the first power transmission shaft 3 of gearbox are provided with first safety pin 5 that can set cut-out power, the second driving motor 2 with the second driving shaft 4 of gearbox are provided with second safety pin 6 that can set cut-out power; In order to the cut-out situation of better tracing detection first safety pin 5 and the second safety pin 6, the first detecting element 8 and the second detecting element 9, first detecting element 8 and the second detecting element 9 is being provided with and is being respectively used to the cut-out situation of detection first safety pin 5 and the second safety pin 6 at dispenser output end.First detecting element 8 and the second detecting element 9 select proximity switch, and the detection signal of the first detecting element 8 and the second detecting element 9 all exports PLC unit, realizes PLC and automatically controls.
Shown in composition graphs 3, control principle of the present utility model: can the first detecting element 8 of whether rotating of detection axis and the second detecting element (being proximity switch) by installing on the distributor power transmission shaft of the first safety pin 5 and the second safety pin 6 rear end, utilize PLC program by the integral operation to the straightener speed of service, velocity product score value is constantly increased along with the increase of time, and carry out clear operation by the triggering signal of proximity switch in increase process.Smoothing roll 10 often rotates a circle under normal circumstances, and proximity switch will produce a triggering signal, and being therefore increased to certain numerical value to the integrated value of main transmission speed will reset.If the first safety pin 5 or the second safety pin 6 are cut off, then there will be the situation that when the first driving motor 1 or the second driving motor run, smoothing roll 10 does not rotate, the velocity product score value continued to increase in PLC then can not be cleared.If be not also cleared when velocity product score value is increased to certain value.Now then judge in program that straightener safety pin cuts off, automatically send the proterctive equipment action of opening roll gap simultaneously, realize the full-automatic process that roll gap is opened automatically.
