Abstract

The utility model discloses a hanging cylinder for hoisting cylindrical heavy goods, which comprises an inner cylinder and an outer cylinder, wherein the inner cylinder is connected with the outer cylinder by reinforcing ribs, and demising space which is used for a hanging board to move is correspondingly arranged on the cylinder walls of the inner cylinder and the outer cylinder; the outer cylinder is divided into two sections which have certain length, and two sections of the outer cylinder are respectively connected with both ends of the inner cylinder through the reinforcing ribs; axial spacing which is between two sections of the outer cylinder forms the demising space for the hanging board to move on the outer cylinder, and the demising space of the inner cylinder is a through hole which is arranged at the intermediate part of the cylinder wall of the inner cylinder. The hanging cylinder which adopts the structure realizes the purpose that the hanging cylinder can obtain sufficient bending strength by lower cost and smaller radial skeleton dimension, and a hanging utensil which adopts the hanging cylinder more economically solves the problem that heavier duty cylindrical heavy goods can be hoisted when the hoisting space is narrow. The hanging cylinder has the advantages of reasonable technological structure, economy and practicality.

Description

Be used to lift by crane the tube that hangs of cylindric weight

Technical field

The utility model belongs to the hoisting technology field, particularly a kind of tube that hangs that is used to lift by crane cylindric weight such as ESR ingot.

Background technology

At present, ESR ingot manufacturer is when the lifting ESR ingot, the suspenders that adopt the cylindric weight of lifting as shown in Figure 1 and Figure 2 more, this suspender is mainly formed by hanging tube 1 and boatswain chair 2, hangs tube 1 for single layer cylindrical tube, evenly is provided with three boatswain chair resigning holes along circumference hanging 1 centre portion, be arranged with vertical hanger 3 in hanging drum outer wall resigning hole both sides, boatswain chair 2 is installed in the hanger crack by axle 4, and an end of boatswain chair is an eccentric, and this end stretches into to hang from resigning hole and also points to a center of hanging in the tube.During the lifting ESR ingot, hang jacket casing and live the ESR ingot cylindrical, crane spurs boatswain chairs around axle 4 upward movements by the axle 5 that is installed on the boatswain chair other end, make the termination of three boatswain chairs choke ESR ingot, at this moment, hang tube bear curved, cut, draw three kinds of stress, and these three kinds of stress can increase along with the increase of ESR ingot diameter and weight, this bending resistance, tension and shear strength that just requires to hang tube also should increase thereupon.Wherein, increase the bending strength hang tube and can hang that barrel is thick to be realized by simple increase, also can be by setting up the reinforced rib 6 (among Fig. 2 shown in the dotted line) of level and realize hanging the upper and lower two parts of tube, though these two kinds of schemes can improve the bending strength of hanging tube, but the former consumption of materials is big, and the cost that can cause hanging tube improves; And the latter's bending strength is directly proportional with the width of reinforced rib, when the lifting narrow space, can not be widened arbitrarily because of reinforced rib lifts space constraint, and the raising of hanging a bending strength is restricted, thereby limit the scope that this structure is hung a hoisting heavy.

The utility model content

The purpose of this utility model is to provide a kind of tube that hangs that is used to lift by crane cylindric weight, and this hangs tube and has certain bending strength, and cost is lower, the radial contour size is less.

For achieving the above object, the technical solution of the utility model has been to adopt a kind of tube that hangs that is used to lift by crane cylindric weight, comprise inside and outside tube, connect by reinforced rib between the inside and outside tube, the corresponding bit space that allows that is used for the boatswain chair motion that is provided with on inside and outside tube barrel;

Described urceolus is to have two sections of certain-length, and two sections urceolus are connected the inner core two ends by reinforced rib respectively; The bit space that allows of boatswain chair motion is formed by the axially spaced-apart between two sections urceolus on the described urceolus, and the bit space that allows on the inner core is the through hole of offering at inner core barrel centre portion;

Described reinforced rib is an annular, is divided into the upper and lower of inner core, and the ring surface of reinforced rib is vertical with the inner core barrel.

The tube that hangs provided by the utility model is owing in adopting, the urceolus double-decker, and be connected into one by reinforced rib, make this hang tube and had stronger bending strength, simultaneously, the material consumption of tube under certain composite bending modulus of hanging of this structure also hung tube less than relying on increase to hang the thick individual layer of barrel merely, its anti-bending strength also is better than the simple individual layer of setting up reinforced rib that relies on and hangs tube, so, when composite bending modulus is identical, the cost that hangs tube provided by the utility model hangs the thick individual layer of barrel less than simple dependence increase and hangs tube, its radial contour size is hung tube less than the simple individual layer of setting up reinforced rib that relies on again, realized that to have under certain bending strength a cost low hanging tube, the purpose that the radial contour size is little adopts the suspender that hangs tube provided by the utility model to solve the problem of lifting by crane than heavy duty roller bearing shape weight comparatively economically when the lifting narrow space.In the utility model, urceolus is divided into two sections, has both satisfied and improved the purpose of hanging a bending strength, saved material again; Simultaneously, form the bit space that allows of boatswain chair by the axially spaced-apart between two sections urceolus, removed processing boatswain chair motion again from and allowed the operation of bit space, process structure is reasonable, and is economical and practical.

The specific embodiment

The suspender that is used to lift by crane cylindric weight shown in Figure 3, improve hanging barrel structure on the basis of existing technology, improvements are: will hang tube and change system into inside and outside two

layered cylinder

7,8 by the individual layer tube, link into an integrated entity by the ring stiffener 6 that is horizontally set on upper and lower two between the inside and outside tube, increase the purpose of hanging a bending strength to reach, use when being suitable for lifting by crane bigger ESR ingot.Urceolus 8 is divided into two sections with certain-length again, two sections urceolus are connected inner core 7 two ends by two ring stiffeners 6 respectively, remain with certain axially spaced-apart 9 between two sections urceolus, as the allow bit space of boatswain chair around axle 4 upward movements, the ring surface of ring stiffener 6 is vertical with the inner core barrel.Evenly be provided with three boatswain chair resigning holes at inner core barrel centre portion one cross-sectional plane upper edge circumference, be arranged with vertical hanger 3 in inner tank theca resigning hole both sides.The axially spaced-apart 9 of the eccentric nose circle of boatswain chair 2 between two sections urceolus, pass crack between two hangers and the boatswain chair resigning hole on the inner core, extend into inner core, point to the inner core center, and by axle 4 and hanger dress connection.Inner core boatswain chair resigning hole quantity and supporting with it boatswain chair, hanger can design as required.

Urceolus 8 also can be made whole urceolus except said structure, the position of corresponding inner core boatswain chair resigning hole is offered and is used for the allow bit space of boatswain chair around axle 4 upward movements on whole urceolus barrel, can realize above-mentioned purpose equally.
