Apply mode.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of protection of the invention.
Embodiment one
As shown in figure 1, Fig. 1 is a kind of descaling spray nozzle targeting testing device that embodiment of the present invention one is provided
Overlooking the structure diagram.
A kind of descaling spray nozzle targeting testing device that the present invention is provided, descaling spray nozzle targeting testing device
It is slidably connected with the rollgang of pickle line processor 100, descaling spray nozzle targeting testing device includes first for be arrangeding in parallel
The slide bar 20 of slide bar 10 and second, the fixed pole 30 and some press strip plate groups that are fixedly connected the first slide bar 10 and the second slide bar 20,
Press strip plate group includes that the two ends of the press strip plate and press strip plate be arrangeding in parallel two-by-two are separately fixed at the first slide bar 10 and the second slide bar
On 20, rubber 60 is fixed in press strip plate group.
It is understood that rubber 60 in the present embodiment can also be replaced with other materials.Other materials need to possess
Following characteristic：After the ejection function of descaling spray nozzle is opened, other materials is receiving the normal work of descaling spray nozzle
Make the injection vestige that can form solid shape under pressure for a period of time.And the geomery of the vestige sprays with high-pressure water descaling
The Normal operating pressure of mouth and the time of injection have specific relation.
Specifically, the first slide bar 10 be arranged in parallel with the second slide bar 20, and the first slide bar 10 and the second slide bar 20 are in the same side
End be fixedly connected with a connecting rod respectively, and then form more firm rectangular configuration.Between two connecting rods
Apart from three fixed poles 30 of interval setting, and the two ends of fixed pole 30 are separately fixed at the first slide bar 10 and the second slide bar 20
On, further enhance the steadiness of the first slide bar 10 and the relative position of the second slide bar 20, i.e. the first slide bar 10 and second and slide
Bar 20 is not easy the relative horizontal displacement of appearance or the displacement of vertical direction.In addition, the first slide bar 10 and the second slide bar 20 it
Between be further fixed on four groups of press strip plate groups.Every group of press strip plate group includes that interval is fixed on the first slide bar 10 and the second slide bar 20 the
One press strip plate 40, the second press strip plate 50 and the rubber 60 on being fixed on the first press strip plate 40 and the second press strip plate 50.In this enforcement
In example, the area that the first press strip plate 40 of covering of rubber 60, the second press strip plate 50, the first slide bar 10 and the second slide bar 20 are enclosed.
In the present embodiment, the spacing between every group of press strip plate group is equal to the spacing between pickle line processor inner high voltage water descaling jet, so as to
When descaling spray nozzle targeting testing device is fixed on specified location in pickle line processor, descaling spray nozzle can be by height
Pressure water is injected on rubber 60.
For the operation principle of further explanation descaling spray nozzle targeting testing device, it is expressed as follows：
After stopping rolling, descaling spray nozzle targeting testing device is placed on the conveying roller 3 of pickle line processor 100,
Then descaling spray nozzle targeting testing device is transmitted by conveying roller 3 to the inside of pickle line processor 100, i.e. water under high pressure is removed
Squama nozzle targeting testing device can slide along the direction that the conveying roller 3 of pickle line processor 100 is rotated, and slidably to smart de-scaling
The inside of machine 100 so that the corresponding descaling spray nozzle of rubber 60；
Open smart de-scaling to wash by water in advance, and check that descaling spray nozzle injection is washed by water in the position of rubber 60 in advance；
Depressing the position to rubber 60 with reference to the pinch roll 2 that pickle line processor 100 is controlled while witness marker portion 70 is carried out
Fine setting, until the scope of attack of descaling spray nozzle is covered in the center of rubber 60.In the present embodiment, witness marker portion
70 are arranged in the lateral grooves of the second slide bar 20, play a part of positioning.
Descaling spray nozzle is opened, and 5- is maintained when the exit hydraulic pressure of descaling spray nozzle is increased to maximum
10S, is then shut off descaling spray nozzle.
A kind of descaling spray nozzle targeting testing device that the present invention is provided, by the He of the first slide bar 10 be arrangeding in parallel
Second slide bar 20, and first slide bar 10 and the second slide bar 20 are fixed together by fixed pole 30, and its spacing is removed with essence
The width correspondence of the rollgang of squama machine 100 so that the first slide bar 10 and the second slide bar 20 fixed by fixed pole 30 can
The sliding on rollgang, while fixing some press strip plate groups between the first slide bar 10 and the second slide bar 20, rubber 60 is covered
The area that lid is enclosed by press strip plate group, the first slide bar 10 and the second slide bar 20, and then rubber 60 can be passed through pickle line processor 100
Rollgang transmit to position corresponding with descaling spray nozzle, without mopping with upset slab, improve detection high pressure
The efficiency of water descaling jet；Rubber 60 is used to affect to judge descaling spray nozzle as by impact object of reference, reducing in addition
The uncontrollable factor of working condition, improves the accuracy of testing result.
Embodiment two
Compared with embodiment one, the difference of embodiment two is that two for being kept completely separate are arranged in press strip plate group
Layer rubber 60, i.e. the ground floor rubber directly facing the descaling spray nozzle for being arranged on the top of pickle line processor 100 and positioned at the
The lower end of one layer of rubber and the second layer rubber for overlapping with ground floor rubber in vertical direction.When ground floor rubber is by positioned at essence
When the descaling spray nozzle on the top of descaling mill 100 carries out strike test, second layer rubber is unaffected, can be while or separately
Receiving the descaling spray nozzle positioned at the bottom of pickle line processor 100 carries out strike test.

In the present embodiment, the first guide groove and the second guide groove are equipped with the through hole of insertion in the horizontal direction, the through hole along the first guide groove and
Second guide groove prolongs raw direction and extends, i.e. the first press strip plate 40 and the second press strip plate 50 can prolong life in the first guide groove and the second guide groove
Direction slide.The convex portion end face at the first press strip plate 40 and the two ends of the second press strip plate 50 is provided with screw, and bolt can pass through through hole
And be threadedly coupled with the screw.And the head diameter of bolt is more than the spacing of through hole in the vertical direction.That is the nut of bolt can
To be stuck in through hole, and then the first press strip plate 40 and the second press strip plate 50 are fastened on the first slide bar 10 and the second slide bar 20.
Thus, convex portion and the bolt of the first press strip plate 40 and the second press strip plate 50 can be passed through, by the He of the first press strip plate 40
Second press strip plate 50 is easy to the quick of rubber 60 flexibly and easily in the first slide bar 10 and the top offset of the second slide bar 20 and fixation
Install and change so that the support being made up of the first slide bar 10, the second slide bar 20 and fixed pole 30 is repeated and utilized, further
Reduce practice shooting test cost；In addition can be by the first press strip plate 40 of adjustment and the second press strip plate 50 so that by first
The descaling spray nozzle of the pickle line processor corresponding with the position of the rubber 60 that the second press strip plate 50 is fixed of press strip plate 40 is arranged, and is reduced
The time of debugging descaling spray nozzle targeting testing device, further improve the effect of detection descaling spray nozzle
Rate.
