Specific embodiment
Below in conjunction with drawings and examples, the specific embodiment of the present invention is described in more details, so as to energy
The advantages of enough more fully understanding the solution of the present invention and its various aspects.However, specific embodiments described below and reality
Example is applied to be for illustrative purposes only rather than limitation of the present invention.
As depicted in figs. 1 and 2, paper machine pressure roller protective device of the invention, including protective device at top 10, foot guard
Device 20 and turning gear 30.It is connected between protective device at top 10 and foot guard device 20 by turning gear 30.Bottom
Protective device 20 is fixed on base plate；The shaft device 30 that can rotate of protective device at top 10 rotates.Protective device at top 10 covers
In 40 surface of pressure roller, protective device at top 10 plays a protective role to pressure roller 40 as a result,.40 phase of protective device at top 10 and pressure roller
To surface curvature it is identical, have gap therebetween, be not in contact.In the paper machine pressure roller protective device practical application of the present invention
In the process, the gap between the surface of protective device at top 10 and pressure roller 40 is not less than 5mm.
Protective device at top 10 is generally formed using steel plate bending, the curvature of curved plates and the surface curvature phase of pressure roller 40
Together.Under normal conditions, steel plate thickness 2mm-8mm.In order to make the surface with good smooth after steel plate bending, one is opened on the steel plate
The aperture of fixed number amount, stress during releasable steel plate bending, the bending machining of steel plate are more easy.Meanwhile perforate on the steel plate,
Be conducive to distributing for the vapor generated in the course of work.
In the paper machine protective device of the present invention, 101 He of reinforcement skeleton that protective device at top 10 is formed by steel-pipe welding
Curved plates are formed.The reinforcement skeleton formed with steel-pipe welding plays booster action to curved plates so that protective device at top
10 more securely, durable.
Matched location hole (not shown) is equipped on protective device at top 10 and foot guard device 20.Such as figure
Shown in 3, positioning bolt 50 is through the location hole on protective device at top 10 and foot guard device 20, by protective device at top 10
(also referred to as " connected ") is fixedly connected with foot guard device 20 together.The position of location hole can be arranged on protective device at top 10
With any position of foot guard device 20, impacted as long as not working equipment.It for convenience, can be by location hole
Arranged on the position that protective device at top 10 and foot guard device 20 are connected by turning gear 30.
Foot guard device 20 mainly prevents that personnel shuttle in a device under inessential state, in order to avoid damage.
Foot guard device 20 is mainly made of bottom skeleton 201 and protective plate 202.It, can be in the protection of foot guard device 20 such as figure
Plate 202 is equipped with machine door 203.Machine door 203 can be opened under necessary situation so that staff can enter equipment and
Equipment is operated or is repaired.
The shaft device 30 that can rotate of protective device at top 10 rotates, and when it turns to operating position, utilizes positioning bolt
50 are fixed together it with foot guard device 20.To further improve security performance, can be set on protective device at top 10
Limiting device is put, is rotated the rotational angle of shaft device 30 with limiting protective device at top 10, protective device at top 10 is avoided to rotate
Angle is excessive.Under general scenario, on the basis of horizontal plane, the maximum rotation angle of protective device at top 10 is 37 °.
In the present invention, it is connected through the hinge and (also referred to as " cuts with scissors between protective device at top 10 and foot guard device 20
Connect "), as shown in Figure 4.First fixed part 301 of hinge is affixed with protective device at top 10 (being fixedly connected), the second fixed part
302 is affixed with foot guard device 20, and the first fixed part 301 and the second fixed part 302 cooperate, by mandrel 303 by two
Part links together.
In order to reduce friction of the protective device at top 10 in rotation process, method can be covered respectively at the both ends of mandrel 303
Blue bushing 304, then flange bushing 304 is embedded in the first fixed part 301 and the second fixed part 302, so by mandrel 303 and first
301 and second fixed part 302 of fixed part separates.Theoretically, the case hardness of mandrel 303 should be made to be more than the hard of flange bushing 304
Degree.Threaded hole can be set at the both ends of mandrel 303, be fixed mandrel 303 by fixing bolt 306 and gasket 305.In general,
Gasket 305 is arranged on the end face of flange bushing 304 outwardly, and the outer diameter of gasket 305 is more than the outer diameter of flange bushing 304, gasket 305
Center sets through hole, through-hole diameter is more than the aperture of 303 both ends threaded hole of mandrel, less than the circumscribed circle on 306 head of fixing bolt
Diameter.
In the present invention, in a non-operative state, protective device at top 10 can be put down paper machine pressure roller protective device, facilitate fortune
It is defeated.During installation, foot guard device 20 is fixed on base plate, protective device at top 10 is directly rotated into operating position,
It is fixed with positioning bolt 50.It in the paper machine, can be to avoid operating personnel when equipment works using pressure roller protective device
Touch accidental injury by mistake, eliminate security risk.
Finally it should be noted that：Obviously, the above embodiment is merely an example for clearly illustrating the present invention, and simultaneously
The non-restriction to embodiment.For those of ordinary skill in the art, can also do on the basis of the above description
Go out other various forms of variations or variation.There is no necessity and possibility to exhaust all the enbodiments.And thus drawn
The obvious changes or variations that Shen goes out is still in the protection scope of this invention.
