Abstract

The utility model discloses a raised buckling head detecting device of hot-rolled band steel, which is respectively installed at the outlet and inlet positions of a machine frame of a hot/rough rolling machine. The raised buckling head detecting device comprises a raised head detecting component and a buckling head detecting component which are arranged up and down. A plate blank with a raised buckling head is in collision with a measuring rod of the raised head detecting component and the buckling head detecting component, so as to drive a rotating shaft to deflect and lead an encoder to carry out detection and send signals to a computer for calculating deflection and giving alarms, thereby realizing automatic and effective detection on the condition of the raised buckling head of the plate blank.

Description

Hot-strip sticks up the discount checkout gear

Technical field

The utility model relates to the hot-strip quality detection technology, more particularly, relates to a kind of hot-strip and sticks up the discount checkout gear.

Background technology

Hot-strip is subjected to that the following table temperature difference on the slab, up-down rollers footpath is poor, the influence of factors such as speed discrepancy and rate of deformation in the operation of rolling, cause in the operation of rolling through regular meeting, and slab produces the phenomenon of nose or discount, thereby influences slab quality.Development along with rolling technique, at present, with roughing, the finish rolling of rolling line with batch three posies to be merged into a post be trend of the times, and after the post merges, operating desk has been cancelled in the roughing zone, makes to have only in the whole rolling process of rough rolling by camera slab to be stuck up discount and observe.But, because the ability of present camera high temperature resistance radiation is relatively poor, operating personnel can't see the stick up discount situation of slab the operation of rolling clearly at all from camera, often need observe the discount situation of sticking up to the scene, greatly reduce the automaticity of production like this, increased workload.

The utility model content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of hot-strip and sticks up the discount checkout gear, and this checkout gear can effectively detect the discount that sticks up of hot-strip.

For achieving the above object, the utility model adopts following technical scheme:

This hot-strip sticks up the place, frame entry and exit that the discount checkout gear is located at the hot rolling roughing mill respectively, the nose detection part and the discount detection part that comprise upper and lower setting, the nose detection part is located at the roller-way top of roughing mill, and the discount detection part is located at the roller-way below of roughing mill.

Described nose detection part comprises bearing block, rotating shaft, several measuring sticks and encoder, and rotating shaft is located on the bearing block, and several measuring sticks are fastened on the rotating shaft below, and encoder is connected in an end of rotating shaft, and is connected to computer.

Described discount detection part also comprises bearing block, rotating shaft, several measuring sticks and encoder, and rotating shaft is located on the bearing block, and several measuring sticks are fastened on the rotating shaft top, and encoder is connected in an end of rotating shaft, and is connected to computer.

The rotating shaft other end of the rotating shaft of described nose detection part and discount detection part all is connected with torsion-bar spring, and the other end of torsion-bar spring is fixed.

Oblique the stretching in the roller-way gap in measuring stick upper end of described discount detection part.

In technique scheme, hot-strip of the present utility model sticks up the place, frame entry and exit that the discount checkout gear is located at the hot rolling roughing mill respectively, the nose detection part and the discount detection part that comprise upper and lower setting, the slab bump that sticks up discount sticks up when having, the measuring stick of discount detection part, thereby drive rotating shaft deflection and detect by encoder, and signal is transported to computer carry out amount of deflection calculating and warning, thereby realize that slab is stuck up the discount situation to carry out automatic and effectively detection.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also Fig. 1, shown in Figure 2, hot-strip of the present utility model sticks up place, frame entry and exit A, the B that discount checkout gear 10 is located at the hot rolling roughing mill respectively, each checkout gear 10 includes the nose detection part 11a and the discount detection part 11b of upper and lower setting, nose detection part 11a is located at roller-way 1 top of roughing mill, and discount detection part 11b is located at roller-way 1 below of roughing mill.Nose detection part 11a comprises bearing block 111a, rotating shaft 112a, several measuring sticks 113a and encoder 114a (PLG), rotating shaft 112a is located on the bearing block 111a, several measuring sticks 113a is fastened on rotating shaft 112a below, encoder 114a is connected in the end of rotating shaft 112a, and is connected to computer (CPU).Discount detection part 11b also comprises bearing block 111b, rotating shaft 112b, several measuring sticks 113b and encoder 114b, rotating shaft 112a is located on the bearing block 111a, several measuring sticks 113b is fastened on rotating shaft 112b top, encoder 114b is connected in the end of rotating shaft 112b, and equally also be connected to computer (CPU), and oblique the stretching in roller-way 1 gap in the measuring stick 113b of discount detection part 11b upper end.In addition, all be connected with torsion-

bar spring

115a, 115b at the rotating shaft 112a of nose detection part 11a and the rotating shaft 112b other end of discount detection part 11b, the other end of torsion-

bar spring

115a, 115b is all fixing, and this torsion-bar spring can be selected comparatively common circular torsion-bar spring for use.

Please in conjunction with shown in Figure 3, the operation principle of this checkout gear 10 is as follows:

Two checkout gears 10 are located at place, entry and exit A, the B of second frame of hot rolling roughing mill respectively, it is rolling that the checkout gear 10 that is installed on exit A is used to detect the strange passage of slab 2, and it is rolling that the checkout gear 10 that is installed on porch B is used to detect the even passage of slab 2.To detect the nose slab is example, when the nose slab 2a that has certain altitude strikes on the measuring stick 113a of nose detection part 11a by roller-way 1 transportation, and measuring stick 113a is upwards deflected, thereby driving rotating shaft 112a upward deflects, encoder 114a detected also and sent pulse signal to computer this moment, and the computer received signal also calculates the angular deflection amount and carries out picture and show and report to the police; In like manner, discount slab 2b can be detected by the measuring stick 113b that strikes discount detection part 11b.And the effect of torsion-bar spring is that postrotational rotating shaft is produced twisting resistance, and rotating shaft and measuring stick are resetted.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
