Abstract
The invention discloses a tool for an inner supporting ring of a drying cylinder. The tool comprises an annular supporting element, a plurality of nuts, and threaded rods matched with the nuts, wherein a plurality of nuts are peripherally and uniformly distributed on the supporting element. All the threaded rods are correspondingly matched with the nuts one by one. Axes of all the threaded rods all pass through the circle center of the supporting element. The tool can adjust the circular degree of the drying cylinder before the inner supporting ring is mounted, thereby guaranteeing that the circular degree of the drying cylinder meets the requirements, and the tooling operation of the inner supporting ring is convenient.
Description
Technical field
The present invention relates to establish frock on a kind of, refer to especially establish frock on a kind of drying cylinder inner supporting circle.
Background technology
The urceolus of diameter Ф large chuck drying cylinder more than 2000 adopts carbon steel/stainless steel roll surface more, and thickness deviation and need to satisfy the static balance requirement when the thickness after the roll surface metalworking satisfied in allowed band (general 2mm).Being rolled up shaped shape affects, and the circularity of drying cylinder generally is the more difficult disposable requirement that reaches, and need to add support ring in drying cylinder, because large-scale drying cylinder roundness deviation is at 20mm, therefore inner supporting circle can't be put in the drying cylinder cylinder at all, cause can't on establish, even if on have the tolerance situation that exceeds standard after establishing.
Summary of the invention
Technical problem to be solved by this invention is: provide on a kind of drying cylinder inner supporting circle and establish frock, establish frock on this and can before inner supporting circle is installed, regulate the circularity of drying cylinder, thereby the circularity of guaranteeing drying cylinder meets the demands, make things convenient for inner supporting circle on establish operation.
For solving the problems of the technologies described above, technical scheme of the present invention is: establish frock on a kind of drying cylinder inner supporting circle, comprise the support member of annular, some nuts and the screw rod that cooperates with nut, these several nut circumference uniform distributions are installed on the support member, each screw rod and nut be corresponding matching one by one, and the axis of each screw rod is all crossed the center of circle of support member.
As a kind of preferred scheme, described support member comprises the support body that is formed by sheet material volume circle and the reinforcement that is welded in the annular of both ends of the surface on the support body.
As a kind of preferred scheme, the identical length of described screw rod is same.
As a kind of preferred scheme, the head of described screw rod is arranged to arc surface.
As a kind of preferred scheme, the shaft of described screw rod and afterbody are equipped with the square stubborn section that spanner is unscrewed or tightened of being convenient to.
After having adopted technique scheme, effect of the present invention is: owing to establishing frock on a kind of drying cylinder inner supporting circle, the support member that comprises annular, some nuts and the screw rod that cooperates with nut, these several nut circumference uniform distributions are installed on the support member, each screw rod and nut be corresponding matching one by one, the axis of each screw rod is all crossed the center of circle of support member, therefore, before inner supporting circle is installed, first should on establish frock and put in the drying cylinder, regulate each screw rod, the head of screw rod is fixed on the drying cylinder inner tube wall, and regulate the length of each screw rod, namely regulate the stressing conditions of each strong point on the whole circumference of drying cylinder inner tube wall, make the circularity of drying cylinder satisfy installation requirement, inner supporting circle can be placed in very smoothly in the inner core and also and between the inner tube wall be welded and fixed like this.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the Facad structure schematic diagram of the embodiment of the invention; ,
Fig. 2 is the local side schematic diagram of the embodiment of the invention;
In the accompanying drawing: 1. support member; 11. support body; 12. reinforcement; 2. screw rod; 21. afterbody; 22. square stubborn section; 23, head; 24. threaded portion; 3. nut.
The specific embodiment
The present invention is described in further detail below by specific embodiment.
As shown in Figure 1, establish frock on a kind of drying cylinder inner supporting circle, comprise support member 1, some nuts 3 of annular and the screw rod 2 that cooperates with nut 3, described support member 1 comprises the support body 11 that is formed by sheet material volume circle and the reinforcement 12 that is welded in the annular of both ends of the surface on the support body 11, can guarantee that like this intensity of this support member 1 meets the demands.These several nut 3 circumference uniform distributions are installed on the support member 1, namely nut 3 is welded on the body of support member 1, each screw rod 2 and nut 3 be corresponding matching one by one, the axis of each screw rod 2 is all crossed the center of circle of support member 1, in the present embodiment, the number of screw rod 2 and nut 3 is 24, and the angle between the screw rod 2 is 15 °.The number of this screw rod 2 is not unique, namely according to the situation of reality, such as the size of drying cylinder, the deformation of drying cylinder the number of screw rod 2 is set reasonably, guarantees that the adjusting of screw rod 2 can make drying cylinder circularity meet the demands.
Wherein, described screw rod 2 is selected the same screw rod of identical length, certainly, and can be not identical yet.
Described screw rod 2 comprises afterbody 21, shaft and head 23.The head 23 of described screw rod 2 is arranged to arc surface, in order to avoid damage the inner core face.
And the shaft of described screw rod 2 comprises threaded portion 24 and square stubborn section, and square stubborn section 22 is arranged between threaded portion 24 and the head 23, and afterbody 21 also is provided with square stubborn section 22, is convenient to the spanner clamping and unscrews or tighten.
During operation, first this frock integral body is put in the inner core of drying cylinder, then adjusting screw(rod) 2 one by one, the head 23 of screw rod 2 is withstood on the inner tube wall, then according to the shape of drying cylinder, the extension elongation of regulating respectively its screw rod 2 is namely regulated the size of the power that is subject to each screw rod 2 strong point on the whole circumference of inner tube wall, thereby to regulating stack shell roundness tolerance ± 1mm, then standard support ring installation in position is welded.
