Abstract

The utility model relates to a rolling wheel cage shoe of mine lifting container, wherein a wheel press cover and bearing press cover of wheel shaft are respectively made into two elements, therefore, when exchanges rubber ring, user only needs to detach the wheel press cover, but not open the bearing press cover, thereby preventing foreign materials as dust and mud from bearing chamber. The utility model uses combined sealing method of oil sealing and sealing ring at the rotational combination of shaft and the bearing press cover, to obtain reliable sealing. A disc spring group of a buffer device is sealed in a cylinder, filled with waterproof lubricant. When adjusts position, user only needs to rotate the cylinder with simple and reliable adjustment. Compared with prior art, the utility model uses the sealing method with combined oil sealing and sealing ring, to obtain reliable sealing and long service. When exchanges the easy-abrasion element as the rubber ring, user only needs to detach the wheel press cover, but not open bearing chamber, to prevent foreign materials as dust and mud from the bearing chamber, therefore, even the bearing is failed, the utility model can avoid dropping wheel, the abraded rubber ring can be exchanged and adjusted easily, and the disc spring group is sealed in the cylinder, with long service life and reliable application.

Description

Rolling cage shoe

Affiliated technical field

The utility model relates to a kind of rolling cage shoe on the mine hoisting container.

Background technology

At present, known rolling cage shoe mainly is made up of wheel shaft, support, shock absorber, bearing and base.See two kinds of structures of " coal mine special equipment atlas " B74 and B86.Known rolling cage shoe, be installed on the lifting container,, all exist important disadvantages though can play certain buffer action, 1) sealing of wheel shaft portion is unreliable, the dustproof and waterproof poor-performing particularly when changing cushion rubber easy to wear, must be opened bearing bore, because the mine site environment is poor, impurity such as dust, muddy water are entered in the bearing bore, can make bearing failure and lost efficacy, thereby cause accidents such as wheel.2) the shock absorber partial spring is all outer naked, and easily aging getting rusty after the cushion rubber wearing and tearing, adjusted difficulty.

Summary of the invention

Unreliable for the wheel shaft portion sealing that overcomes on the existing rolling cage shoe, dustproof and waterproof poor performance and partial spring are outer naked, and be easily aging, shortcoming such as easily get rusty.The utility model proposes the rolling cage shoe of a kind of brand new wheel shaft and shock absorber structure.Its sealing is more reasonable, is difficult for entering impurity such as dust and muddy water, reliable operation, and the life-span is long, and the worn-down cushion rubber is changed easy to adjust.

The technical scheme that its technical matters that solves the utility model adopts is: the utility model rolling cage shoe is assembled by cooperations such as wheel shaft, shock absorber, support, bearing and bases, end at axle is equipped with bearing, lock by nuts and washers, on the outer ring of bearing, wheel end cap (21) and cushion rubber (7) are housed, on wheel end cap (21), take turns gland (8) and (10) two parts of bearing gland with bolt respectively, in the rotation junction of axle (20), oil sealing (14) and seal ring (12) are housed with bearing gland (10); On the orienting sleeve in shock absorber (27), disk spring (26) is housed, cylinder (25) upper end is sealed and matched with joint sliding, the junction device has seal ring (23), cylinder (25) lower end and orienting sleeve (27) lower end are by bolt (28) sealing and fixing, and orienting sleeve (27) and disk spring (26) all are sealed in the cylinder (25), fill with waterproof grease in the cylinder, shock absorber (3) is installed between support (2) and the bearing (4), is connected by bearing pin (6).

This practical beneficial effect is, owing to adopted such scheme, rolling cage shoe sealing of the present utility model is reliable, is difficult for entering impurity such as dust and muddy water, and the reliable operation life-span is long, and the replacing of worn-down cushion rubber is easy to adjust.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples:

Accompanying drawing 1 is a construction profile scheme drawing of the present utility model;

Accompanying drawing 2 is a Facad structure scheme drawing of the present utility model;

Accompanying drawing 3 is the structural representation of the utility model wheel shaft;

Accompanying drawing 4 is a shock absorber structural representation of the present utility model;

Among the figure, 1. wheel shaft, 2. support, 3. shock absorber, 4. bearing, 5. base, 6. bearing pin, 7. cushion rubber is 8. taken turns gland, 9. bolt, 10. bearing gland, 11. back-up ring, 12. seal rings, 13. axle sleeves, 14. oil sealings, 15.O RunddichtringO, 16. bolt, 17. bearings, 18. jam nuts, 19. retaining washers, 20., 21. the wheel end cap, 22. joints, 23. seal rings, 24. adjusting disks, 25. cylinders, 26. disk spring, 27. orienting sleeves, 28. bolts, 29. screw rods, 30. adjustment tooling holes.

The specific embodiment

In Fig. 1, captive joint with an end of axle (20) in the hole of support (2) upper end, the hole of support (2) lower end is connected by bearing pin (6) with bearing (4), the joint (22) of shock absorber (3) upper end and the screw rod (29) of lower end are connected with bearing pin with the bearing upper right side with support (2) upper right side respectively, bearing (4) is fixed by bolts on the base (5), base (5) is installed on the lifting container, when the lifting container oscilaltion, cushion rubber (7) on the wheel shaft (1) moves along lifter cage guide scroll-up/down, because the lifter cage guide is installed equal error, make roller (1) by support (2), with bearing pin (6) is that the center produces certain swing, and cushion by the disk spring (26) in the shock absorber (3), make lifting container energy smooth running, after the wearing and tearing of cushion rubber (7) operation certain hour, can adjust by the rotation of cylinder (25) in the shock absorber (3), convenient especially.When cushion rubber (7) wearing and tearing are changed, only need pull down wheel gland (8) and need not open bearing gland (10) and can change easily.

In Fig. 3, adorn two antifriction-bearing boxs (17) at an end of axle (20), jam nut (18) and retaining washer (19) are fixed on bearing (17) inner ring on the axle (20).Dress is by wheel end cap (21) on the outside race.Wheel gland (8) and bearing gland (10) are made two parts and are contained on the wheel end cap (21), use bolt respectively.Cushion rubber (7) is contained on wheel end cap (21) and the wheel gland (8).Charge of oil envelope (14) and seal ring (12) between bearing gland (10) and spool (20) seal with O RunddichtringO (15) between bearing gland and the wheel end cap, thereby the combination sealing mode that formation rubber seal and mechanical seal combine makes sealing more reliable.The other end of axle (20) is fixed on the support (2).When cushion rubber (7) when cage guide is made rolling-operation, friction driven wheel end cap, wheel gland, bearing gland rotate axle, and carry out combination sealing by oil sealing (14) and seal ring (12).Prevent that foreign material such as dust, muddy water from entering in the bearing bore.

In Fig. 4, shock absorber center tap (22) and screw rod (29) are connected with bearing (4) with support (2) respectively with bearing pin.Disk spring group buffer system is made up of joint (22), adjusting disk (24), disk spring (26), orienting sleeve (27), all is contained in the leak free cylinder (25).When rolling cage shoe moved, the swing that support produces moved up and down along orienting sleeve (27) by joint (22), disk spring (26) and to cushion, and lifting container can be moved reposefully.The orienting sleeve cylindrical is a circle and smooth conduit, the orienting sleeve endoporus is threaded structure, it and screw rod normal-running fit are installed, when the position between needs adjustment cushion rubber and cage guide, with excellent class instrument, by adjusting with tooling hole (30), rotor (25), drive orienting sleeve (27) inner bolt hole and do relative rotation, adjust height and change with screw rod (29), convenient, flexible.Because whole disk spring group is sealed in the cylinder, fills with the waterproof lubricating grease in the cylinder, prevented to get rusty, reliable operation, the life-span is long.
