Abstract
The invention discloses a shaft type lifting system for protecting a steel wire rope, and belongs to the technical field of lifting equipment. The shaft type lifting system for protecting the steel wire rope comprises a shaft type lifting point and the steel wire rope, wherein an external contour type protective cover in sliding fit with the shaft type lifting point is arranged outside the shaft type lifting point, and covers the external of the shaft type lifting point; the steel wire rope is lifted outside the external contour type protective cover; and baffle plates respectively in stop fit with the external contour type protective cover are fixed at the two ends of the shaft type lifting point. The shaft type lifting point generates no direct contact with the lifting steel wire rope; in the lifting and overturning process, the lifting steel wire rope is only contacted with the external contour type protective cover; and the lifting steel wire rope and the external contour type protective cover are kept relatively stationary without sliding and rubbing, so that the damage caused by the sliding and the rubbing of the steel wire rope is reduced, and the service life of the steel wire rope is prolonged. Therefore, the shaft type lifting system can guarantee difficult damage of the steel wire rope in the lifting process.
Description
Technical field
The present invention relates to a kind of Lift-on/Lift-off System can protecting steel wire cable, a kind of shaft type Lift-on/Lift-off System protecting steel wire cable, belongs to hanging device technical field specifically.
Background technology
At present, in traditional chemical plant hoisting technology, particularly tower kind equipment is when lifting, the form of the more employing tube shaft type lifting lug of main hanger, and in hoisting rig, the connecting portion of shackle mostly also is bearing pin form, in hoisting process, steel rope directly contacts this type of shaft type suspension centre, and steel wire cable is meeting and bearing pin relative sliding in lifting switching process, and the friction of steel wire cable and bearing pin also can cause comparatively major injury to steel rope, make steel rope be easy to damage, cause service life of steel wire rope to reduce.
Summary of the invention
The object of the present invention is to provide a kind of shaft type Lift-on/Lift-off System protecting steel wire cable, cause steel wire cable to hold damageable technical matters with the hanging device steel wire cable and the bearing pin relative sliding in hoisting process that solve prior art.
The present invention adopts following technical scheme: a kind of shaft type Lift-on/Lift-off System protecting steel wire cable; comprise shaft type suspension centre and steel wire cable; the gallery type protecting sleeve with shaft type suspension centre bearing fit is provided with outside described shaft type suspension centre; it is outside that described gallery type protecting sleeve is set in shaft type suspension centre; described steel wire cable is lifted on outside described gallery type protecting sleeve, and the two ends of described shaft type suspension centre are fixed with the baffle plate coordinated with gallery type protecting sleeve block respectively.
The removable two ends being fixedly mounted on shaft type suspension centre of described baffle plate.
Described gallery type protecting sleeve offers the oil hole for injecting lubricating oil to shaft type suspension centre and gallery type protecting sleeve junction.
The invention has the beneficial effects as follows: shaft type suspension centre is nested in gallery type protecting sleeve by the present invention, adopt shaft type suspension centre and gallery type protecting sleeve as agent structure, can ensure in lifting operation, present system main body can bear lifting load, the baffle plate at shaft type suspension centre two ends can prevent the landing of gallery type protecting sleeve, shaft type suspension centre does not occur directly to contact with lifting steel wire cable, in lifting switching process, lifting steel wire cable only contacts with gallery type protecting sleeve, lifting steel wire cable and gallery type protecting sleeve keep geo-stationary, do not slide, cliding friction can not be produced, thus the damage that minimizing steel wire cable cliding friction causes, extend the life-span of steel wire cable.Therefore the present invention is used can to ensure that steel wire cable is not fragile in hoisting process.
Further, baffle plate is that detachable can facilitate the present invention to use the dismounting of front and back, after lifting operation completes, can retain whole system to treat repeatedly to use, also can disassemble according to actual conditions.
Further, can inject lubricating oil from outside oil gun in oil hole, lubricating oil can enter into the junction that shaft type suspension centre and gallery type protect axle, and the friction between shaft type suspension centre and gallery type protecting sleeve is reduced, thus extends the service life of system.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The structure of a kind of specific embodiment of the present invention as shown in Figures 1 to 4; originally be the shaft type Lift-on/Lift-off System of the protection steel wire cable of embodiment; comprise shaft type suspension centre 1 and steel wire cable 3; the gallery type protecting sleeve 2 with shaft type suspension centre 1 bearing fit is provided with outside shaft type suspension centre 1; it is outside that described gallery type protecting sleeve 2 is set in shaft type suspension centre 1; described steel wire cable 3 is lifted on outside described gallery type protecting sleeve 2; the two ends of described shaft type suspension centre 1 are fixed with the baffle plate 21 coordinated with gallery type protecting sleeve 2 block respectively, the removable two ends being fixedly mounted on shaft type suspension centre 1 of baffle plate 21.Gallery type protecting sleeve 2 offers the oil hole 21 for injecting lubricating oil to shaft type suspension centre 1 and gallery type protecting sleeve 2 junction.
Shaft type suspension centre is nested in gallery type protecting sleeve by the present invention; adopt shaft type suspension centre and gallery type protecting sleeve as agent structure; can ensure in lifting operation; present system main body can bear lifting load; the baffle plate at shaft type suspension centre two ends can prevent the landing of gallery type protecting sleeve, and baffle plate is that detachable can facilitate native system to use the dismounting of front and back, after lifting operation completes; whole system can be retained to treat repeatedly to use, also can disassemble according to actual conditions.Can inject lubricating oil from outside oil gun in oil hole, lubricating oil can enter into the junction that shaft type suspension centre and gallery type protect axle, and the friction between shaft type suspension centre and gallery type protecting sleeve is reduced, thus extends the service life of system.Shaft type suspension centre does not occur directly to contact with lifting steel wire cable; in lifting switching process; lifting steel wire cable only contacts with gallery type protecting sleeve; lifting steel wire cable and gallery type protecting sleeve keep geo-stationary; do not slide; can not cliding friction be produced, thus the damage that minimizing steel wire cable cliding friction causes, extend the life-span of steel wire cable.Therefore the present invention is used can to ensure that steel wire cable is not fragile in hoisting process.
In actual applications, the quantity of steel rope can be selected according to actual needs flexibly, can adopt steel cable, also can adopt the steel rope of more than two.
Above-described embodiment is a kind of preferred embodiment of the present invention, when the present invention lifts use always, the present invention can be arranged to non-removable structure, and now, extenal fixation baffle plate can be fixed on shaft type suspension centre by the mode of welding.Oil hole on gallery type protecting sleeve also can be offered according to actual needs.
