CN201227648Y - Roll changing carriage journey detection apparatus of rolling mills - Google Patents

Abstract

The utility model provides a journey detect device of a mill roll changing carriage. The device comprises an encoder which is installed on the output shaft of the encoder, and is characterized in that a gear wheel is arranged on the output shaft of the encoder and a rack is arranged on rails of the roll changing carriage; and the gear wheel arranged on the output shaft of the encoder is directly engaged with the rack. Because the rack is arranged on the rails of the roll changing carriage, the gear wheel arranged on the output shaft of the encoder is directly engaged with the rack arrange on the rails so that the accuracy of the encoder numeration is improved, the migration distance of the roll changing carriage can be controlled accurately, the occurrence of the migration error of the roll changing carriage is reduced, the time when the roll is replaced is saved, the production efficiency of the product can be improved. Therefore, the manufacturing cost can be reduced.

Description

The rolling mill changer device for detecting distance of travel

Technical field

The utility model belongs to technical field of steel rolling, relates to rolling machinery maintenance and the affiliated facility of changing, and specifically is a kind of checkout gear that is used to detect the rolling mill changer stroke.

Background technology

At present; what general cold rolling unit adopted is the continuous rolling technology production strip steel of 5 frames or 7 frames; in order to satisfy the technological requirement of producing; the steel plate that assurance rolls out reaches demanding criteria on surface and thickness; stipulate to change working roll rolling in the milling train in per 24 hours; in the process of changing working roll; will be to the control of roll change garage journey; to guarantee that roll changing carriage accurately is parked in the fixed position; and the checkout gear that present rolling mill changer adopts in the process of dividing a word with a hyphen at the end of a line is the mode of encoder numeration; what lean on is the gear on the encoder output shaft and the mode of the gears engaged on the travelling wheel; this mode stability is not high; usually can cause that the encoder numeration is inaccurate because of travelling wheel idle running; thereby it is not in place that roll changing carriage is divided a word with a hyphen at the end of a line, and needs operating personnel to carry out manual operation, prolonged roll changing time; thereby reduction production efficiency has also increased the unsafe factor of producing simultaneously.

The utility model content

The utility model provides a kind of rolling mill changer device for detecting distance of travel, to solve the problem that former rolling mill changer device for detecting distance of travel exists.

The purpose of this utility model is achieved in that it comprises encoder, and encoder is installed on the encoder output shaft, is characterized in, establishes tooth bar on the roll changing carriage track, direct geared on the encoder output shaft and tooth bar engagement.

The utility model is owing to establish tooth bar on the roll changing carriage track, make direct geared and the engagement of track upper rack on the encoder output shaft, can improve the accuracy of encoder numeration, the accurate control roll changing carriage distance of dividing a word with a hyphen at the end of a line, reduce the divide a word with a hyphen at the end of a line generation of fault of roll changing carriage, save roll changing time, improve the production rate, and then reach the purpose that reduces production costs.

Description of drawings

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the vertical view of Fig. 1,

Fig. 3 is Figure 1A place enlarged drawing,

Fig. 4 is Fig. 2 B place enlarged drawing.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Shown in Fig. 1,2,3,4, it comprises encoder 7, and encoder 7 is installed on the encoder output shaft 6, gear 4 is being installed on the encoder output shaft and is established 5 in tooth on the roll changing carriage track, gear 4 and tooth bar 5 engagements.When roll change begins, the milling train rolling screen door is opened, equipment moves to the roll change position between frame, afterwards, roll changing carriage 1 is driven by the motor 2 that is positioned on the car body, moves to frame 8 directions along track 3, in the process of dividing a word with a hyphen at the end of a line, gear 4 pinion racks 5 rotate, and drive encoder output shaft 6 and rotate, and then make encoder 7 obtain spin data, note the number of turns of rotation, calculate the number of turns that gear should rotate by formula N=S/ (π * D), thereby the control roll changing carriage distance of dividing a word with a hyphen at the end of a line, wherein S is the roll changing carriage distance of dividing a word with a hyphen at the end of a line, N is the gear rotating cycle of encoder record, D is the gear compound graduation circular diameter, after roll changing carriage 1 arrives shelf position, carry out roll change, after the roll change, roll changing carriage returns according to original course, and mode is the same.

Claims (1)

1 one kinds of rolling mill changer device for detecting distance of travel, it comprises encoder, encoder is installed on the encoder output shaft, it is characterized in that, gear is being installed on the encoder output shaft and is established tooth bar on the roll changing carriage track, the wheel and rack engagement.
