Abstract
The utility model relates to a dual-head rotation elevator. The elevator includes a high-intensity nut and two bearing sleeves nested at the two ends of the high-intensity nut, wherein a middle shaft is arranged in each bearing sleeve; a clamp spring is nested on each middle shaft; an oil seal is arranged on each clamp spring; a centring bearing is arranged on each oil seal; a pressure bearing is arranged on each centring bearing; a centring pressure bearing is arranged on each pressure bearing; a locking pin is arranged on each centring pressure bearing; the centring bearing, the pressure bearing and the centring pressure bearing are fixed on each middle shaft through the locking pin; a groove, an upper through hole and a lower through hole are arranged on each bearing sleeve; and both the upper and the lower through holes are communicated with the groove. The dual-head rotation elevator provided by the utility model can rotate at the two heads through changing the structural design of the elevator, so as to guarantee the normal operation of the other head when one head thereof does not rotate, and further avoid accidents caused by deficiencies of the prior art; meanwhile, the service lives of the steel wire rope and the elevator are prolonged, the economic benefit is improved, and the construction safety is guaranteed.
Description
Technical field
The utility model relates to a kind of double end changes elevator.
Background technology
Existing elevator is the rotation of single head list, when quitting work, if clot appears in the consistent then wire rope with the wire rope direction of rotation of elevator work direction of rotation; If share split appears in the opposite then wire rope with the wire rope direction of rotation of elevator work direction of rotation, break up and twist off phenomenon, cause drilling rod to hang thing easily, cause damage.
The utility model content
The utility model provides a kind of double end to change elevator at existing single head elevator above shortcomings.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of double end is changeed elevator and is comprised high strength nut, be nested in two bearing holder (housing, cover)s at the two ends of described high strength nut, be provided with an axis in described each bearing holder (housing, cover), be nested with jump ring on the described axis, described jump ring is provided with oil sealing, described oil sealing is provided with alignment bearing, described alignment bearing is provided with pressure bearing, described pressure bearing is provided with the centering pressure bearing, described centering pressure bearing is provided with stop pin, described alignment bearing, pressure bearing and centering pressure bearing are fixed on the axis by stop pin; Respectively have a groove on described each bearing holder (housing, cover), go up through hole and lower through-hole, described upward through hole and lower through-hole all connect with groove, and described elevator is the double end rotation.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the position near jump ring has relief groove on the described bearing holder (housing, cover).
Further, described groove is a U type groove.
Further, described cross section of going up through hole is oval, and the cross section of described lower through-hole is circular.
The beneficial effects of the utility model are: the utility model double end is changeed elevator by changing the structure design of elevator, reaches the double end rotation, and guaranteeing elevator when not rotating for one, the other end can operate as normal, and the accident that defective causes before avoiding takes place; Prolong the application life of wire rope and elevator simultaneously, improved economic benefit, guaranteed construction safety.
Description of drawings
Fig. 1 changes the structural representation of elevator for the utility model double end.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, described double end is changeed elevator and is comprised high strength nut 10, be nested in two bearing holder (housing, cover)s 11 at the two ends of described high strength nut 10, be provided with an axis in described each bearing holder (housing, cover) 11, be nested with jump ring 1 on the described axis, described jump ring 1 is provided with oil sealing 2, described oil sealing 2 is provided with alignment bearing 3, described alignment bearing 3 is provided with pressure bearing 4, described pressure bearing 4 is provided with centering pressure bearing 5, described centering pressure bearing 5 is provided with stop pin 6, described alignment bearing 3, pressure bearing 4 and centering pressure bearing 5 are fixed on the axis by stop pin 6; Respectively have a groove 12 on described each bearing holder (housing, cover) 11, go up through hole 8 and lower through-hole 9, described upward through hole 8 and lower through-hole 9 all connect with groove 12.Position near jump ring 1 on the described bearing holder (housing, cover) 11 has relief groove 7.Described groove 12 is a U type groove.Described cross section of going up through hole 8 is oval, and the cross section of described lower through-hole 9 is circular, and described elevator is the double end rotation.
The oiling of elevator of the present invention is divided into two, guaranteeing one when immersing water, the other end can operate as normal, can in time overhaul and prevent wire cable rupture, it is not smooth to use jump ring can prevent that oil sealing from contacting use with axis, and the design of relief groove can avoid hypertonia to enter dirt.
Elevator of the present invention after capel and wire rope connected, is put into capel one end groove of elevator in use again, use and sell directly to households in the hole of inserting the oval cap of elevator one end band, the other end be circular hole with pin and catch pinning, make to connect and finish; The other end is connected with the weight drilling rod, and there is an inclined to one side head junction, puts into the groove of the elevator other end, with the Same Way locking, just can use.Elevator of the present invention is easy for installation, and reliable lock is applicable to that single wire rope lift heavy thing uses.
When single rope crane is worked, wire rope is rotation constantly, elevator of the present invention can be along the both direction rotation of wire rope in crane work process, make single rope be in normal nature, wire rope should be when being weighed down power and when the bob thing lands, and two revolving forces of rope are dissolved along with the rotation of elevator of the present invention.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
