A kind of galvanizing furnace roller is changed special hanger
The utility model relates to a kind of suspender, and especially a kind of galvanizing furnace roller is changed special hanger, belongs to the corollary equipment technical field on cold rolling hot dip galvanizing production line.
According to the applicant understood, steel mill's Reheating Furnace Zone replacing furnace roller generally adopts the C type hook of coordinative composition of equipments to change at present, due to design reasons, factory building height is limited, and C type hook is high approximately 3 meters, and traveling crane gib head probably only has 3.5 meters to furnace roller, the one, balance is difficult to grasp, and rocking property is very large.The 2nd,, the complete operant level of dependency line turner, its driving driver's cabin can not move in the centre of runway grider, and driving work sight line is for stravismus angle, if misoperation can cause security incident, or causes the infringement of refractory equipment in stove.The 3rd, changing needs furnace temperature to drop to personnel to pass in and out in stove, because use this rocking property of C type hook large, need personnel to enter in stove and hold, and in stove, have toxic gas, to personnel, can produce injury.Therefore C type hook uses very inconvenient.
Retrieval is found, application number is: the utility model patent of 201020210050.X discloses a kind of replacing tool for furnace roller of soaking pit furnace, main technical schemes for arranging suspension hook, block, balancing weight, a word beam hanger and balancing weight hanger on a word beam, fixedly suspension hook and block below a word beam one end, a word beam fixedly the other end of suspension hook be provided with balancing weight, directly over one word beam fixed stop, separately fix a word beam hanger, the top fixed weight piece hanger of balancing weight.The relative general operation mode of this patented technology has improved replacing speed, but complex structure, cost is high but also need to arrange and change different balancing weights according to calculation of parameter such as concrete furnace roller, word beams, more loaded down with trivial details.
Utility model content
The purpose of this utility model is: the problem existing for above-mentioned prior art, propose a kind of simple in structure, turn waste into wealth, galvanizing furnace roller with low cost, safe and convenient to use changes special hanger.
In order to reach above object, a kind of galvanizing furnace roller of the present utility model is changed special hanger, comprise the furnace roller body with turning cylinder, also comprise locking device, described locking device is hollow tubular structure, described locking device top is provided with the first hanger, one end of described locking device is fixedly connected with one end of described furnace roller body turning cylinder, the other end of described furnace roller body turning cylinder is covered in the metal tube being connected with furnace roller body, described metal tube outer wall is concordant with furnace roller body, and the top of described metal tube outer wall is provided with the second hanger; Described first, second hanger is in same plane; The described locking device other end is connected with outside turning cylinder one end that is replaced furnace roller.
Further, described locking device is locking axle sleeve.
Further, described furnace roller body is waste and old furnace roller, by discarded furnace roller again twice laid, with low cost, economize on resources, easy to use, has very strong practicality.
Further, described metal tube is the steel pipe welding with furnace roller body.
Further, described metal tube diameter is identical with furnace roller body.
Further, described locking device other end outer wall is provided with securing member.
The utility model structural principle is fairly simple, changes furnace roller and within 3 hours, now needs only 2 hours by originally changing one, can save 1 hour.Check man is workable, after traveling crane gets up, reaches height, and balance is grasped by check man oneself, does not need traveling crane gib head just to regulate.Meanwhile, till temperature does not need reduction personnel to pass in and out in stove, use this Novel sling, check man does not enter operation in stove again, outside stove, can complete replacing operation, has reduced risk, has improved security, has ensured personal safety.
In addition, compared with prior art, the utility model structure is simpler, assembles conveniently, and replacing speed improves, and has improved operating efficiency, and twice laid simultaneously, has saved resource.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the hanger structure schematic diagram of the utility model embodiment.
Fig. 2 is schematic diagram when suspender is changed furnace roller described in Fig. 1.
Fig. 3 is the structural representation of the waste and old furnace roller of the employing of suspender described in Fig. 1.
The specific embodiment
A kind of galvanizing furnace roller of the present embodiment is changed special hanger, and basic structure as shown in Figures 1 to 3, comprises furnace roller body 1 and the locking axle sleeve 2 with turning cylinder 5; Locking axle sleeve 2 is hollow tubular structure, locking axle sleeve 2 tops are provided with the first hanger 3, one end of locking axle sleeve 2 is fixedly connected with one end of turning cylinder 5, the other end of turning cylinder 5 is covered in the steel pipe being connected with furnace roller body 1, outer wall of steel pipe is concordant with furnace roller body 1, the diameter of steel pipe is identical with the diameter of furnace roller body 1, and the top of outer wall of steel pipe is provided with the second hanger 4; First, second hanger is in same plane; The other end of locking axle sleeve 2 is connected with outside turning cylinder one end that is replaced furnace roller.
In order to economize on resources, cut the waste, furnace roller body 1 adopts waste and old furnace roller, and locking device other end outer wall is provided with securing member 6, further reinforces and changes furnace roller, prevents from changing furnace roller landing.
By the steel pipe in waste and old discarded furnace roller body 1 other end welding same diameter, increase the weight of suspender end, the other end of locking axle sleeve 2 is inserted in needs to change furnace roller, make suspender end weight be greater than the furnace roller weight that needs replacing, then with chain block and steel wire rope, make hoist cable, be connected respectively with two hangers, after the weight trim of two ends, with driving hook, new furnace roller or old furnace roller are lifted up into and hung out, design of the present utility model takes full advantage of obsolete material, and cost is lower, saved resource, easy to use, replacing speed is fast, safe and applicable.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
