Specific embodiment

In the following, with reference to attached drawing, structure and operation principle to the utility model etc. are further described.

Referring to Fig. 2~Fig. 7, the De-scaling box of the utility model, including babinet 1 and the case lid 2 for being covered on babinet 1, in babinet 1 Equipped with two rows of descaling jets 3 being used for steel slab surface spray high pressure water, the front of the two rows descaling jet 3 is respectively equipped with a use In the water fender 4 for preventing high pressure water from splashing, which is fixed on case lid 2.

As shown in Fig. 2, the De-scaling box of the utility model further includes the hydraulic cylinder 12 for case lid 2 to be driven to be opened and closed, the hydraulic pressure Cylinder 12 is installed on by stent 13 on roller-way beam 14, and stent 13 is fixed on roller-way beam 14, and the cylinder body of hydraulic cylinder 12 is articulated with branch Frame 13；One end of babinet 1 is equipped with the shaft 7 that can be rotated relative to babinet 1, and one end of case lid 2 is fixedly connected with shaft 7, case Lid 2 can be rotated with the rotation of shaft 7, so that 2 open or close of case lid is in babinet 1.Specifically, shaft 7 and hydraulic cylinder 12 it Between be equipped with connecting rod 9, one end of connecting rod 9 is connected by key with shaft 7, and the other end of connecting rod 9 passes through axis pin 10 and hydraulic cylinder 12 Piston rod 11 is hinged.

As shown in Fig. 2, when the piston rod 11 of hydraulic cylinder 12 is retracted, 9 drive shaft 7 of connecting rod rotates counterclockwise so that case The direction of lid 2 to close babinet 1 rotates case lid 2 being closed to babinet 1；As shown in figure 3, the piston rod 11 when hydraulic cylinder 12 is stretched When going out, 9 drive shaft 7 of connecting rod rotates clockwise so that case lid 2 is rotated to the direction far from babinet 1 case lid 2 to be opened, just Water fender 4 on the descaling jet 3 and case lid 2 in maintenance or replacement babinet 1.By setting hydraulic cylinder 12, facilitate case lid 2 Opening and closing, it is easy to operate and save the time.

To reduce deflection of the case lid 2 in rotation process, increase the intensity of case lid 2, if preferably, case lid 2 by A dry connecting plate 6 is fixedly connected with shaft 7, may insure the driving torque of shaft 7, and ensure that the deflection of case lid 2 is smaller. As shown in figure 4, being set on case lid 2 there are four connecting plate 6, connecting plate 6 is welded and fixed with case lid 2 and shaft 7.

After case lid 2 is opened, since 4 position of water fender is very high, operating personnel is needed to complete the maintenance of water fender 4 by ladder And replacement, if in the process, hydraulic cylinder 12 breaks down, case lid 2 is caused to fall suddenly under the action of dead weight, is easily sent out Raw safety accident.Therefore, as further improvement of the utility model, the limiting dress that setting is needed to prevent case lid 2 from falling suddenly It puts, specifically, as shown in figure 4, shaft 7 is connected with hook 8, correspondingly, as shown in Fig. 5~Fig. 7, babinet 1 is equipped with for limiting Spacer pin 16 when hydraulic cylinder 12 drives case lid 2 to turn to certain position, is penetrated pin hole 15, so by the pin hole 15 that pin 16 passes through Hook 8 is hooked on spacer pin 16 afterwards, at this point, the position of case lid 2 is defined, it will not be unexpected because hydraulic cylinder 12 breaks down It falls.Preferably, hook 8 can be connected by key with shaft 7, to ensure that hook 8 is rotated synchronously with shaft 7.

As shown in fig. 7, after case lid 2 is opened, the residing height difference of two water fenders 4 on case lid 2 is fixed on, when two Water fender 4 all far from babinet 1 to easy access and replace position when, the height positioned at the water fender 4 of upside is very high, operator Member's needs are climbed to very high position and are operated, and safety accident easily occurs.Therefore, in order to avoid the generation of safety accident, case Lid 2 can be there are two open position, and Fig. 6 to show the first open position of case lid 2, which is suitble to upside Water fender 4 is overhauled and is replaced；Fig. 7 show the second open position of case lid 2, which is suitble to downside Water fender 4 is overhauled and is replaced.

Specifically, babinet 1 is equipped with two pin holes 15 corresponding with above-mentioned two open position respectively.As shown in fig. 6, When the water fender 4 to upside is overhauled and replaced, spacer pin 16 need to be penetrated to the pin hole 15 of upside, hook 8 is hooked in the limit So that case lid 2 is limited in the first open position on the pin 16 of position；As shown in fig. 7, when the water fender 4 of downside is overhauled and is replaced When, spacer pin 16 need to be penetrated downside pin hole 15, hook 8 hook on the spacer pin 16 so that case lid 2 is limited in the second opening Position.

More than, the only schematic description of the utility model, it will be recognized by those skilled in the art that without departing from this practicality On the basis of novel operation principle, a variety of improvement can be made to the utility model, this belongs to the protection of the utility model Range.
