Abstract
A hoisting device of a spray gun small cart gas pipeline relates to fixing devices for oxygen-enriched air pipelines during smelting process and is characterized by structurally comprises a section of cylindrical device casing, an upper connecting rod, a buffer spring and a lower portion connecting plate, wherein a through hole is arranged in the middle of an upper top plate of the casing, the upper end of the upper connecting rod penetrates through the through hole arranged at the upper end of the device casing, a straight rod vertically located in the device casing and a horizontal support plate fixedly connected to the bottom of the straight rod, the buffer spring is a pressure spring and is sleeved on the upper connecting rod located on the device casing, and the lower portion connecting plate is a hanging plate fixed under a lower base plate of the device casing. The hoisting device of the spray gun small cart gas pipeline can effectively reduce vibration amplitude of a small spray gun pipeline and has very good buffer effect on structural torsion of the pipeline and a spray gun support caused by torsional moment due to two metal flexible pipes, and is simple in structure, safe and reliable.
Description
Technical field
A kind of erecting by overhang of spray gun dolly gas pipeline, a kind of fixing device that is used for smelting process oxygen-enriched air pipeline of brook master, the particularly oxygen channel of metallurgy of nickel oxygen-enriched top blowing stove spray gun dolly hang the device on dolly.
Background technique
In oxygen-enriched top blowing nickel fusion process, top blast stove spray gun dolly is used for fixing spray gun, and attached oxygen channel, technology airduct road, cover ventilation duct etc., and its oxygen pipeline is hung and normally adopted fixed fastening hanging.Spray gun inserts molten bath 200mm～300mm usually in fusion process, and high velocity air is through spray gun outlet vigorous stirring melt, and it is more violent that reaction force makes that spray gun clocklike rocks with irregular vibration.Thereby each structure of conduct vibrations to spray gun top drives spray gun oxygen pipe vibration, and the displacement amount that is caused by vibration is bigger.In addition,, receive the influence of its deadweight, the oxygen pipeline is had certain torsional moment because two metallic hoses that are connected with spray gun oxygen rigid tubing are connected on the root branch vertical tube of horizontal oxygen pipeline; And between the blowing position, certain move distance is arranged from locking bit at spray gun, the moment of torsion to the oxygen pipe takes place to continue to change at the volley.
Because vibration is bigger and do not have buffering energy-absorbing structure, the influence of torsional moment in addition causes the fixed tightening nut of hanging loosening easily, need carry out fastening operation continually, and there is very big potential safety hazard in the spray gun safe operation.
Summary of the invention
The purpose of the utility model is exactly the deficiency that exists to above-mentioned prior art.Provide a kind of and can effectively reduce spray gun oxygen Analysis of Pipe Vibrations amplitude; And pipeline that the torsional moment that two strip metal flexible pipes are brought causes and gunjet rack construction torsion problem have fine buffer function, the erecting by overhang of simple in structure, safe and reliable spray gun dolly gas pipeline.
The purpose of the utility model is through realizing with technological scheme.
A kind of erecting by overhang of spray gun dolly gas pipeline is characterized in that its structure comprises:
Device case-this housing is one section barrel-type casing, has a through hole between two parties at the upper plate of housing;
Top coupling rod-this connecting rod be the upper end through have in the device case upper end through hole, vertically be positioned at the straight-bar of device case and be fixed in the horizontal supporting plate of straight-bar bottom;
Damping spring-this spring is a pressure spring, is set on the top coupling rod that is positioned at device case;
Bottom joining plate-this bottom joining plate is fixing vertical plate under the device case lower shoe down.
The erecting by overhang of a kind of spray gun dolly gas pipeline of the utility model is characterized in that described bottom joining plate is two, and the lower end has bolt hole.
The erecting by overhang of a kind of spray gun dolly gas pipeline of the utility model; Can effectively reduce spray gun oxygen Analysis of Pipe Vibrations amplitude; And pipeline that the torsional moment that two strip metal flexible pipes are brought causes and gunjet rack construction torsion problem have fine buffer function, and be simple in structure, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the device of the utility model.
Structural representation during the use of the device of Fig. 2 the utility model.
Embodiment
A kind of erecting by overhang of spray gun dolly gas pipeline, its structure comprises:
Device case 3-this housing is one section barrel-type casing, has a through hole between two parties at the upper plate of housing;
Top coupling rod 1-this connecting rod be the upper end through have in the device case upper end through hole, vertically be positioned at the straight-bar of device case and be fixed in the horizontal supporting plate 4 of straight-bar bottom;
Damping spring 2-this spring is a pressure spring, is set on the top coupling rod that is positioned at device case;
Bottom joining plate 5-this bottom joining plate is fixing vertical plate under the device case lower shoe down.
During use, a kind of top coupling rod of erecting by overhang of spray gun dolly gas pipeline is fixed on the top blast stove spray gun dolly 6, the bottom joining plate intersects relatively with fixed plate on the oxygen pipeline 7 and joins, by bolt; When its oxygen pipeline receives action of high-speed airflow; When thereby each structure of conduct vibrations to spray gun top drives spray gun oxygen pipe vibration; Transfer of vibration is to the pressure spring in the utility model device; Pressure spring produces reaction force, and effectively restriction conduit is because straight-line displacement amount and the swing offset amount that vibration causes; Simple in structure, satisfactory for result.
