Abstract
The utility model discloses a telescopic lifting lug comprising a lifting lug seat provided with a hollow mounting cavity, and a lifting lug body arranged in the hollow mounting cavity, wherein one segment (matched with lifting equipment) of the lifting lug body can be stretched out or retracted back to the hollow mounting cavity, and a limiting structure for limiting the lifting lug body from integrally sliding out from the hollow mounting cavity is arranged on the lifting lug seat; and an elastic element used for propelling the lifting lug body to stretch out from the hollow mounting cavity is also arranged in the hollow mounting cavity. The lifting lug body of the telescopic lifting lug disclosed by the utility model can integrally retract back into the lifting lug seat so as not to generate interference with a rolling mill honorific arch during an assembly process, and no groove is processed on a corresponding position of the rolling mill honorific arch, thereby guaranteeing the rigidity of the honorific arch and the precision of a finished product; meanwhile, after the lifting lug is installed on a roller box, the lifting lug is unnecessary to be frequently disassembled or assembled during a successive roller changing process, and the lifting lug body can automatically popup and retract back during the roller changing process, so that the operation is simple, the roller changing time is short and the production efficiency can be improved; and the lifting lug can form an integral with the roller box after being assembled, and scattered pieces are avoided, so that the lifting lug is unlikely to lose.
Description
Technical field
The utility model relates to a kind of mechanical device, particularly a kind of hanger.
Background technology
Universal mill is a four-high mill, and four rollers comprise 1 pair of horizontal roller and 1 opposite roller, and wherein edger roll is assemblied among the roller case.
When roll change, for being changed, hangs away by the roller case, need hanger to be set in roller case both sides.Be convenient lifting, hanger must protrude the outline of roller case.Because of the roller case slides in memorial archway, so dovetail groove has been offered to avoid the interference with hanger in the relevant position of memorial archway.The consequence that causes thus is the weak link that this dovetail groove has become memorial archway, has weakened the integral rigidity of memorial archway, and this precision for mill product is disadvantageous.
One of solution of the problems referred to above is to adopt detachable hanger.Promptly after the roller case is changed the lifting completion, hanger is dismantled, again horizontal roller and edger roll case are pushed in the mill housing.This moment, the dovetail groove of memorial archway can be cancelled, and avoided rigidity to weaken.Yet this solution is brought new problem again: when roll change once more, need artificial to go above hanger is assembled to the roller case, the mounting or dismounting that do not stop like this seem and very bother, and have consequently prolonged roll changing time, have reduced production efficiency; Simultaneously detachable hanger is little loose mail, often loses easily in operation site.
Therefore need improve roller case hanger of the prior art, to solve the problem that it exists.
Summary of the invention
In view of this, the purpose of the utility model provides a kind of concertina type hanger, and its existence can not impact memorial archway rigidity, and the while without the frequent change hanger, can shorten roll changing time when lifting roller case, be applicable to universal mill roller case.
The utility model concertina type hanger; Comprise being provided with hanger seat that cavity is installed and being arranged at the hanger body of installing in the cavity that a section of cooperating with lifting appliance of said hanger body can stretch out to be installed cavity and hanger seat with retraction and be provided with and limit the position limiting structure that hanger body integral body skids off the installation cavity; Also be provided with in the said installation cavity and be used to promote the flexible member that the hanger body stretches out the installation cavity.
Further, said hanger seat comprises the tubulose pedestal, and the tube chamber of said tubulose pedestal is the installation cavity;
Further, said position limiting structure is the ring-type pressing plate that is arranged at the tubular holder end of body and inwardly extends along the tube chamber footpath;
Further, said flexible member is a spring;
Further, an end relative with the ring-type pressing plate on the said tubulose pedestal is provided with base plate, and said base plate is provided with the lead with the tube chamber axially parallel, and said spring overcoat is on lead;
Further, also be provided with the pilot hole that is used to hold spring on the said hanger body.
The beneficial effect of the utility model: the utility model concertina type hanger; Because the hanger body can wholely be withdrawn in the hanger seat; Therefore when assembling, can not interfere, thereby make that also noting be used in the mill housing relevant position slots, and has guaranteed memorial archway rigidity and finished product accuracy with mill housing; After hanger is installed on the roller case, just need not frequently to install and remove hanger in the roll change process afterwards simultaneously, and the hanger physical efficiency ejects automatically and withdrawal when roll change, easy and simple to handle, roll changing time is short, can enhance productivity; Hanger just becomes integral body with the roller case after assembling, no scattered, be difficult for losing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the utility model concertina type Lifting Lug Structure sketch map;
Fig. 2 is the utility model concertina type hanger and mill housing mated condition sketch map.
The specific embodiment
Fig. 1 is the utility model concertina type Lifting Lug Structure sketch map; Fig. 2 is the utility model concertina type hanger and mill housing mated condition sketch map.
As shown in the figure; Present embodiment concertina type hanger; Comprise being provided with hanger seat that cavity 1 is installed and being arranged at the hanger body of installing in the cavity 2 that a section of cooperating with lifting appliance of said hanger body 2 can stretch out to be installed cavity 1 and hanger seat with retraction and be provided with and limit the position limiting structure 3 that hanger body 2 integral body skid off installation cavity 1; Also be provided with in the said installation cavity 1 and be used to promote the flexible member 4 that hanger body 2 stretches out installation cavity 1.
When present embodiment concertina type hanger is installed, its need roller case 5 be provided with one lay the hanger seat pilot hole, make the hanger seat be embedded and be assembled on the roller case 5; And an inclined-plane or chamfering are set on memorial archway, so that when assembling, it can be compressed into into the installation cavity by suitable to hanger body 2 applied thrusts.Since hanger body 2 can whole withdrawal hanger seat in, therefore when assembling, can not interfere (as shown in Figure 2), thereby also make and not be used in mill housing 6 relevant positions fluting with milling train mill housing 6, guaranteed memorial archway rigidity and finished product accuracy; After hanger is installed on the roller case 5, just need not frequently to install and remove hanger in the roll change process afterwards, and hanger body 2 can eject automatically under the effect of flexible member 4 when roll change simultaneously; And can under ramp effect, can withdraw automatically; Easy and simple to handle, roll changing time is short, can enhance productivity; Hanger just becomes integral body with roller case 5 after assembling, no scattered, be difficult for losing.
