Description

A kind of suspender for lifting wheel

Technical field

The utility model relates to overhead hoist technical field, more particularly, relates to a kind of suspender for lifting wheel.

Background technology

Wheel is as the important spare part of train, and play a part to support the weight of whole train and propulsive effort and braking force are passed to rail, its quality direct relation safe in operation and passenger's security of the lives and property of train.Wheel is being carried out in the process of machine up, need by wheel handling repeatedly, as shown in Figure 1, its outline is circular cone structure to the main TV structure schematic diagram of wheel, and is provided with the annular flange of protrusion at bigger diameter end.

Due to the needs of machinework and transport, usually need to carry out handling to wheel, but wheel does not allow offer lifting screw, the location needs to wheel when the suspender such as suspender belt, chain sling can not meet again machinework, so will adopt ring forging suspender.When wheel rim is positioned at lower end, conventional ring forging suspender can carry out handling to wheel, but, need when carrying out machinework to wheel to overturn wheel, when wheel rim is positioned at upper end, due to the existence of wheel rim, ring forging suspender inwardly cannot block wheel, lifting insecure, easily cause personal safety accident and wheel mass accident, is all a kind of potential threat to operating personal and wheel itself.Therefore, need a kind of wheel special hanger to meet wheel lifting demand.

By patent retrieval, the technical scheme about suspender is existing open.Chinese Patent Application No.: 201120168334.1, the day for announcing: on December 14th, 2011, invention and created name is: General lifting appliance for locomotive wheels, this application case discloses a kind of General lifting appliance for locomotive wheels, comprises suspension ring, steel rope and suspension hook, and steel rope has three, one end of every root steel rope is connected with suspension ring, the other end is connected with suspension hook, and steel rope is connected with suspension hook by boatswain chair, and boatswain chair is rotaryed connection with suspension hook by bearing pin.Normal-running fit between design suspension hook and boatswain chair, adapts to the change of wheel height, has commonality, but easily scratch wheel surface, and not easily locate during Three-jaw sling trailer wheel, easy slippage with this.

Chinese Patent Application No.: 201420076890.X, the day for announcing: on July 2nd, 2014, invention and created name is: a kind of hook for annulus part of slinging, this application case discloses a kind of hook for annulus part of slinging, comprise pipe link and hook plate, described pipe link is formed by connecting by two pieces of points of plates in 120-150 ° of angle, one end of pipe link is fixed on hook plate, pipe link is connected with hook plate point plate is vertical with hook plate arranges, the pipe link other end is provided with the connecting bore be connected with lifting machine, its pipe link is 120-150 ° of angle.When sling annulus part time, hook plate can rotate under gravity, make hook plate horizontal by angle, thus avoid extension annular workpiece thereon and come off, the face that simultaneously face that contacts with pipe link of hook plate i.e. hook plate contact with annular workpiece adopts sphere, so just can make to avoid when contacting with annular workpiece causing damage to its contact surface, but this hook lifts by crane from annulus endoporus, cannot position wheel when machinework, and cannot take out after placing, be not suitable for wheel lifting.

Detailed description of the invention

For understanding content of the present utility model further, by reference to the accompanying drawings and embodiment the utility model is described in detail.

Embodiment 1

Composition graphs 1, Fig. 2, Fig. 3 and Fig. 4, a kind of suspender for lifting wheel of the present embodiment, be made up of suspension ring 1, steel rope 2 and suspension hook 4 etc., suspension hook 4 in the present embodiment has two, and as shown in Figure 2, two suspension hooks 4 are connected on suspension ring 1 by steel rope 2, suspension hook 4 is hinged with lifting shackle 3, suspension hook 4 is connected with steel rope 2 by lifting shackle 3, has both avoided steel rope 2 and has directly contacted with suspension hook 4 wearing and tearing caused, facilitated again the replacing of suspension hook 4 or steel rope 2.

Suspension hook 4 in the present embodiment comprises upper hook body 401, curved cross member 402 and lower hook body 404, the connecting panel that described upper hook body 401 is 130 ° ~ 150 ° by two pieces of angles is formed, the present embodiment preferably 145 °, when sling wheel 5 time, because Action of Gravity Field makes the L shape hook pin section of stretching out horizontal by certain angle, ensure that wheel 5 can not come off.

Offer circular hole in upper hook body 401 one end and be hinged by this circular hole and lifting shackle 3, the other end of upper hook body 401 is connected in the center of curved cross member 402 upper side.The arc radius of curved cross member 402 is 400 ~ 550mm, specific to being 500mm in the present embodiment, and the angle opening of the circular arc opening of curved cross member 402 and upper hook body 401 is towards the same side, the setting of this circular arc adds the area of contact of suspension hook 4 and wheel 5, and a pair lower hook body 404 at two ends, curved cross member 402 downside can be made to fit tightly with wheel 5 outer round surface, the location of suspension hook 4 on wheel 5 when being convenient to handling, strengthens the steadiness of lifting.Lower hook body 404 is provided with wheel rim arc 403, and the circular arc opening of the circular arc opening of this wheel rim arc 403 and curved cross member 402 is towards the same side, when the wheel rim of the wheel 5 lifted is positioned at upside, this wheel rim arc 403 can block the wheel rim of wheel 5.The lower end of described wheel rim arc 403 is connected with L shape hook pin, the section of stretching out of this L shape hook pin is point to the sphenoid of wheel rim arc 403 open side, and the outer end of the section of stretching out is the tip of sphenoid, its sphenoid structure is conducive to L shape hook pin to stretch on the downside of wheel 5, is convenient to lifting.

In order to avoid wheel 5 surface is scratched, the lower hook body 404 of the suspender of the present embodiment is set with rubber coating.Because the height of usual processed wheel 5 is between 140 ~ 160mm, the inner arc radius of wheel rim arc 403 is set to 30mm by the present embodiment, the inner arc center of circle of wheel rim arc 403 is set to 140mm to the minor increment of sphenoid upper side, wheel rim arc 403 span is 40mm, it arranges and the wheel 5 of height between 140 ~ 160mm can be sling by the suspension hook 4 in the present embodiment, practical.

During concrete use, hung over by suspension ring 1 on elevator machinery hook, the L shape hook pin of lower hook body 404 inserts on the downside of wheel 5, and two suspension hooks 4 are symmetrically distributed on the same omnibearing line of wheel 5.If wheel rim is in downside, lower hook body 404 blocks wheel 5 makes it come off, and can directly lift by crane; If wheel rim is positioned at upside, then when lifting, wheel rim can snap in wheel rim arc 403 automatically, and L shape hook pin is auxiliary fixing bottom wheel 5 simultaneously, by very firm the slinging of wheel 5.When adopting the present embodiment suspender lifting wheel 5, firmly, safety is good in lifting, can not scratch wheel 5 surface, and structure is simple, is convenient to promote the use of.

Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
