Abstract
The utility model discloses a device for replacing a belly pipe of a blast-furnace tuyere. The device comprises a support base (1) and a support rod (2), wherein the support rod (2) is fixedly connected to the support base (1). The device for replacing the belly pipe of the blast-furnace tuyere is formed by fixedly connecting the support rod to the support base, a belly pipe fixing hole is formed in the top of the support rod, when the belly pipe of the blast-furnace tuyere needs replacing, the device is fixed on a forklift which is used for carrying and installing and replacing small sets, thus being convenient and rapid. The device is in a compact structure, can reduce labor intensity of workers sharply, can shorten the time for replacing the belly pipe of the blast-furnace tuyere, improves work efficiency, lowers the damping down ratio of the blast furnace, and improves the economic benefits of enterprises.
Description
Technical field
The utility model belongs to smelting equipment technical field, further belongs to ironmaking equipment technical field, is specifically related to a kind of simple in structurely, simple for production, and the blast-furnace tuyere belly pipe of being convenient to mechanical engagement operation is changing device more.
Background technology
In the smelting operation of prior art, blast-furnace tuyere belly pipe is the visual plant of blast furnace air inlet system, it is being undertaken and is sending hot blast to task in blast furnace, the hot blast temperature of blowing due to blast furnace maintains 1150-1200 ℃ substantially, even higher, under the environment of the high heat of high temperature, work, blast-furnace tuyere belly pipe belongs to consumable accessory, need to regularly replace.Current domestic blast furnace maximizes, and air-supply arrangement maximizes, and the blast-furnace tuyere belly pipe bodily form is large and heavy, and stokehold and pipe arrangement operative employee are in Renewal process, and workload is large, and labour intensity is high, and the replacing time is long, inefficiency, but also there is potential safety hazard.For this reason, develop a kind of simple in structure, change safe and simplely, the high blast-furnace tuyere belly pipe of working efficiency more changing device is the effective way addressing this problem.
Utility model content
It is a kind of simple in structure, simple for production that the purpose of this utility model is to provide, and the blast-furnace tuyere belly pipe of being convenient to mechanical engagement operation is changing device more.
The purpose of this utility model is achieved in that and comprises support base and supporting bar, and described supporting bar is fixed on support base.
The utility model adopts combination support structure, blast-furnace tuyere belly pipe is changed easier.Its supporting bar top is provided with belly pipe fixed orifices, while changing blast-furnace tuyere belly pipe, more changing device is fixed on fork truck, and support base is provided with the spacing guide frame coordinating with the holder of fork truck fork, there is guide effect and also can prevent skew, utilize fork truck carry out the carrying of little cover and install and change, convenient and swift.The utility model compact construction, can significantly alleviate labor strength, can shorten the time that blast furnace is changed air port belly pipe, has improved working efficiency, has reduced blast furnace staying rate, has improved Business Economic Benefit.
Accompanying drawing explanation
Fig. 1 is the utility model one-piece construction schematic diagram.
In figure: 1-support base, 2-supporting bar.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but must not to the utility model, be limited by any way, any change or the improvement based on the utility model training centre, done, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises support base 1 and supporting bar 2, and described supporting bar 2 is fixed on support base 1.
Described supporting bar 2 tops are provided with straight blowing pipe of blast furnace fixed orifices.
Described supporting bar 2 tops are U-shaped structure, suitable with belly pipe external form.
Described supporting bar 2 tops are Y-shaped structure, suitable with belly pipe external form.
Described supporting bar 2 is symmetrical structure.
Described supporting bar 2 is inclined type structure, and high one end, one end is low.
Described supporting bar 2 is no less than two.
Described supporting bar 2 is hollow tubular structures or solid tubular structure.
Described supporting bar 2 wall thickness are 10 ~ 20mm.
Described support base 1 is provided with and adapts to the spacing guide frame that the holder of fork truck fork coordinates.
the utility model principle of work and working process:
The utility model adopts supporting bar to be fixed on support base, is made into more changing device of blast-furnace tuyere belly pipe, with the support structure that is connected, utilizes fork truck carry out the carrying of little cover and install and change, convenient and swift.
During work, operator are fixed on this device on fork truck, the air port belly pipe of required replacing is placed in to supporting bar top and fixes, can change, and support base is provided with the spacing guide frame coordinating with the holder of fork truck fork, utilizes the more stable carrying of carrying out air port belly pipe of fork truck and installs and change.More changing device is used the belly pipe dismounting of front single air port and installation to need 40min, after using, the dismounting of single air port belly pipe and installation only need 20min, have shortened the replacing time of air port belly pipe, shorten the time of blast furnace staying simultaneously, be beneficial to blast furnace and recover, increase blast furnace production capacity.Owing to adopting fork truck to change, reduce labour intensity and workload, improved production efficiency.
By damping down 1 hour, will affect 220 tons of output, change every year belly pipe 25 times, 2500 yuan/ton of ton iron costs.That is: avoid 4,500,000 yuan/year of loss=((40-20)/60) * 220 * 2500 * 25 ≈.
