Abstract
The utility model discloses a converter hood lifting device, comprising four synchronous hydraulic cylinders, a position sensor and a water cooling pull rod. The four synchronous lifting hydraulic cylinders are horizontally placed on a maintenance platform above a hood. A head part of the hydraulic cylinder is connected with its own chain through a joint. The other end of the chain is connected through the joint with the water cooling pull rod which is connected with the converter hood. Four grooved wheels are respectively fixed on the maintenance platform above the four water cooling pull rods. The chain passes the grooved wheel and the grooved wheel changes the moving direction of the chain from horizontal to vertical. The chain and the water cooling pull rod drive the converter hood to ascend and descend steadily to realize the lifting function of the converter hood. The converter hood lifting device overcomes the shortage of using a hoisting device lifting converter hood and a hydraulic cylinder vertical hanging type lifting converter hood device, and has advantages of steady and reliable operation, reasonable utilization of converter system space, safe and reliable repair and maintenance, time and labor saving equipment replacement and no hidden danger.
Description
Technical field
The utility model belongs to the metal smelt field, particularly a kind of revolving furnace fume hood jacking system.
Background technology
At present, the revolving furnace fume hood jacking system mainly contains two kinds of patterns: a kind of employing winding plant, drive steel rope by the direct motor drive reel, and walk around fixed pulley lifting revolving furnace fume hood.This device transmission is not steady, causes the equipment scratching easily, and is relatively harsher to space requirement.The another kind of employing vertically hung the hydraulic actuating cylinder form, and hydraulic actuating cylinder hangs upside down above revolving furnace fume hood, directly is connected on the petticoat pipe body by the water-cooled pull bar, realizes the lifting of petticoat pipe by the hydraulic actuating cylinder lifting.This mode can be saved the space, but maintenance, safeguards very difficultly, has huge potential safety hazard.
Summary of the invention
The revolving furnace fume hood jacking system that the purpose of this utility model is to provide a kind of and operates steadily, is convenient to safeguard.
For achieving the above object, the revolving furnace fume hood jacking system that the utility model provides is made up of four synchronous hydraulic cylinders, position transduser, water-cooled pull bar, four synchronization lifting hydraulic actuating cylinders are lain in a horizontal plane on the inspection platform of petticoat pipe top, the hydraulic actuating cylinder head is connected with separately rope chain respectively by joint, the rope chain other end is connected with water-cooled pull bar on being connected revolving furnace fume hood by joint, 4 sheaves are separately fixed on the inspection platform of 4 water-cooled pull bar tops, the rope chain is by sheave, and sheave is vertical with rope chain movement direction by level conversion.
Be equipped with band nylon cushion board mount in the jacking system that the utility model provides under the hydraulic actuating cylinder head body.
Revolving furnace fume hood jacking system described in the utility model is compared with existing revolving furnace fume hood jacking system, four synchronization lifting hydraulic actuating cylinders lie in a horizontal plane on the inspection platform, there is the nylon cushion board mount to make this device operate steadily under the hydraulic actuating cylinder head body and reliably also rationally utilizes the converter system space, repair and maintenance is safe and reliable, equipment replacement is time saving and energy saving, does not have potential safety hazard.
Description of drawings
Accompanying drawing 1 is a petticoat pipe jacking system partial schematic diagram.
Accompanying drawing 2 is a petticoat pipe jacking system birds-eye view.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
In Fig. 1 and Fig. 2, the revolving furnace fume hood lifting is placed on the steel structure inspection platform with hydraulic actuating cylinder 5 levels, and hydraulic actuating cylinder 5 afterbodys are connected with support 7 usefulness bearing pins, this support 7 and the bearing bolt together that is welded on the platform.Below hydraulic actuating cylinder 5 heads, be equipped with the support 6 of band nylon backing plate, avoid friction and protection hydraulic actuating cylinder 5 surfaces between cylinder body and the platform not easy to wear, guarantee that hydraulic actuating cylinder 5 always is horizontal.The flexible position control of hydraulic actuating cylinder level is finished by the position transduser that it carries.The hydraulic actuating cylinder head is connected with separately rope chain 3 respectively by joint, and rope chain 3 other ends are connected with the water-cooled pull bar 4 of direct connection on revolving furnace fume hood by joint, and this regional temperature is than higher, and the water-cooled pull bar substitutes the function of the rope chain 3 of part linear portion.The high-low limit of two limit switch 2 control petticoat pipes.4 sheaves 1 are separately fixed on the inspection platform of 4 water-cooled pull bar 4 tops, and rope chain 3 is by sheave 1, and sheave 1 transfers rope chain 3 sense of motions vertically to by level, and sheave 1 existing location has the function that turns to again.Rope chain 3 can select for use the rope chain also can select leaf chain for use, adopts the bigger leaf chain traction revolving furnace fume hood lifting effect of intensity better.4 lifting hydraulic cylinders 5 synchronization telescope under the control of hydraulic efficiency pressure system drives the steadily lifting together of rope chain 3, water-cooled pull bar 4 and revolving furnace fume hood, thereby realizes the revolving furnace fume hood elevating function.
Claims (2)
1. revolving furnace fume hood jacking system, by four synchronous hydraulic cylinders (5), position transduser, water-cooled pull bar (4) is formed, it is characterized in that: four synchronization lifting hydraulic actuating cylinders (5) are lain in a horizontal plane on the inspection platform of petticoat pipe top, the hydraulic actuating cylinder head is connected with separately rope chain (3) respectively by joint, rope chain (3) other end is connected with water-cooled pull bar (4) on being connected revolving furnace fume hood by joint, 4 sheaves (1) are separately fixed on the inspection platform of 4 water-cooled pull bars (4) top, rope chain (3) is by sheave (1), and sheave (1) is vertical with rope chain (3) sense of motion by level conversion.
2. according to the described revolving furnace fume hood jacking system of claim 1, it is characterized in that: band nylon cushion board mount (6) is arranged under the described hydraulic actuating cylinder head body.
