Abstract
The utility model provides a novel Muffle pipe hoisting clamp which comprises two C-shaped clamps arranged at the lower part of a flange, a vertical rib connecting plate used for connecting the two C-shaped clamps, lifting lugs arranged on the two sides of the C-shaped clamps, and a press plate. The novel Muffle pipe hoisting clamp is characterized in that an insert plate is movably connected on the C-shaped clamps through a bolt, a waist-shaped hole is formed on the insert plate, and the press plate is movably mounted on the insert plate through a bolt that passes through the waist-shaped hole. Regardless of the deformation of the Muffle pipe, the C-shaped clamps are mounted smoothly to meet the hoisting requirements and gives full play to the advantages particularly when the Muffle pipe is in elliptic shape, thereby achieving the effect of successful one-step hoisting.
Description
Technical field
The utility model relates to a kind of stone tongs, is suitable for the installation of muffle tube equipment in the annealing furnace equipment, can be applicable to have the equipment use of same case simultaneously.
Background technology
The large-scale production line that is used for the stainless steel band bright annealing that manufactures and designs by Austrian EBNER company, it is the state-of-the-art bright annealing manufacturing line of present domestic introduction, its bottom-to-top-height is 56m, and can handle width is 650-1350mm, and thickness is the 0.2-3.0mm stainless steel sheet strip.Wherein, annealing furnace adopts vertical Muffle furnace.Muffle furnace is the key equipment that guarantees stainless steel band lightization, and big (leading dimensions is φ 1800mm * 27939mm), weight big (weight is 18000kg during leading dimensions) to the muffle tube size, and service conditions is abominable, filling 100%H in inside during annealing in the stove
2Protective atmosphere; 40 LPG combustion gas or natural fuels burners of arranging according to certain rule of being symmetrically distributed in body of heater 180 degree both sides of outside employing are used for the heating muffle body of heater; normal working temperature in the Muffle furnace is 1095-1150 ℃; maximum operating temperature can reach 1200 ℃, and whether its normal operation directly has influence on the quality and the output of stainless steel sheet strip bright annealing.
The annealing furnace scheme drawing as shown in Figure 4, stove is by inlet seal case, body of heater, cooling section, compositions such as backward channel.Muffle tube is installed in the body of heater, and its top flange and cooling section bolted connection with the silicone rubber O-ring sealing, in the unsettled insertion inlet seal case of bottom, charge into quench hot oil therebetween in the inlet seal box body, to cut off muffle tube and combustion chamber.Band steel operation scheme is a upstriker, promptly is with steel to enter from the stove bottom, comes out from stove top, arrives backward channel by the cooling section slewing rollers.
Muffle tube installation process operation is as follows:
(1) shifts out band steel in the stove
(2) dismounting cooling section and body of heater section and backward channel flange face tie bolt
(3) remove cooling section equipment
(4) top flange face suspender is installed, is hung out muffle tube to middle lifting flange face place
(5) spacer flanger face anchor clamps are installed, are hung out muffle tube
Because of the lifting of device structure design decision muffle tube need be finished in two steps.The first step: muffle tube upper flange face lifting.It uses two ear studs to be mounted on flange face, then lifting.Second step: muffle tube spacer flanger face lifting.Use unit clamp to be installed on the muffle tube, the hanger on the hoisting fixture lifts then.In whole hoisting process, the lifting of second step can be used and use a unit clamp.The structure of these anchor clamps as shown in Figure 3.
This clamping and hoisting tool divides four parts: 1. C type anchor clamps, 2. stud connecting panel, 3. hanger, 4. pressing plate.It is installed in muffle tube spacer flanger face step following (as Fig. 2):
(1) the muffle tube flange face position that mediates
(2) mobile C type anchor clamps, muffle tube is clamped in the flange face bottom that mediates, and muffle tube weight is pressed on the C type anchor clamps fully
(3) the vertical rib plate connecting panel is installed, is connected two C type anchor clamps
(4) hanger is installed in C type anchor clamps both sides
(5) pressing plate is installed, C type anchor clamps and muffle tube spacer flanger face are buckled together
But, when muffle tube in use for some time, muffle tube integral body can be the distortion of banana sigmoid, spacer flanger face place cross sectional shape will no longer be just round, draw central flange face maximum gauge difference according to the pipe diameter take off data and reach 200mm (because of the reason of bending is very complicated, this paper is not analyzed).In this time, unit clamp can't adapt to the ovalizing deflection of body to be installed, so anchor clamps can't be installed in the middle of the muffle tube on the lifting flange face, and the weight of whole muffle tube can't be caused lifting muffle tube by fixture support.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel muffle tube stone tongs, and the lifting after the muffle tube flexural deformation is not subjected to the restriction of anchor clamps.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of novel muffle tube stone tongs comprises:
Two C type anchor clamps are arranged on the flange face bottom and clamp muffle tube;
The stud connecting panel connects two C type anchor clamps;
Hanger is installed in the sidepiece separately of two C type anchor clamps;
Pressing plate;
It is characterized in that:
Plate, plate is provided with waist shaped hole, is movably connected on two C type anchor clamps by bolt;
Described pressing plate passes waist shaped hole with bolt and is installed on the plate movably.
As improvement, described plate comprises four little plates that are symmetrically distributed on two C type anchor clamps both sides and two big plates that are symmetrically distributed in two C type anchor clamps middle parts.
As improvement, the outer ledge of described little plate middle part is withstood with the through hole that a bolt passes adapter plate, makes little plate maintain the trend that holds out against to the inside.
As improvement, the central axis of the waist shaped hole on the described little plate passes the stone tongs axle center, and the central axis of the waist shaped hole on the big plate is parallel with the stone tongs perpendicular line.
At last, described plate inboard comprises that big plate, little plate and pressing plate inboard be arranged to the arcwall face of certain angle.
Compared with prior art, advantage of the present utility model is: pressing plate can movablely be installed, muffle tube is supported by the stud connecting panel, when muffle tube is deformed into ellipse, can move the pressing plate position on waist-shaped hole, reach the purpose that supports muffle tube weight and C type anchor clamps and muffle tube spacer flanger face are buckled together, these anchor clamps have reached good effect, have reduced plant maintenance work capacity and labour intensity, have saved the maintenance cost of equipment, improved production efficiency, simple and practical.
