Abstract
An upper hanging type sliding door load-bearing wheel set structure is characterized by comprising a wheel frame (1); a supporting shaft (2) penetrates into a hole which is formed in the upper end of the wheel frame (1); load-bearing wheels (3) are symmetrically installed at two ends of the supporting shaft (2); rolling surfaces of the load-bearing wheels (3) are adhered to inclined surfaces of guide rails (4); double rows of self-aligning roller bearings (5) are arranged inside the load-bearing wheels (3); seal covers (6) are installed on external sides of the load-bearing wheels (3); wool felt dustproof rings (7) are installed on internal sides of the load-bearing wheels. The upper hanging type sliding door load-bearing wheel set structure has the advantages of effectively disintegrating weight of a heavy horizontal sliding type steel door, greatly improving load-bearing capability and achieving easy open and close of a large-sized steel horizontal sliding door.
Description
Technical field
The invention belongs to building unit technical field, specifically just relate to heavy parallel-moving type steel door, especially can realize the upper hanging type sliding door load-bearing wheel group structure that a body easily opens and closes.
Background technology
In industries such as military project, nuclear power, heavy-duty machineries, in order effectively to realize building or some key area to the requirement of the specific functions such as safety, shielding, anti-radiation and to facilitate current unification, in some occasions, heavy parallel-moving type steel door often to be set.Owing to considering multi-functional composite demand, these steel sliding door products are designed to large scale, large weight conventionally.Cause like this for the steel door opening and closing of these occasions comparatively slowly, need to overcome larger frictional resistance could realize.
Generally speaking, in employing, the mode of load-bearing can effectively reduce the frictional resistance in large scale, large weight door running body, for realizing the light keying of door body, has created advantage.Realize heavy door body and easily open and close, key is to improve the weight capacity of load-bearing wheels.The weight capacity of general upper load-bearing wheels is limited, often can only be applicable to the parallel-moving type steel door that load-bearing tonnage is lower.
Utility model content
The purpose of this utility model is for the limited defect of load-bearing wheels weight capacity on existing heavy parallel-moving type steel door, and a kind of novel upper hanging type sliding door load-bearing wheel group structure is provided, and can significantly improve weight capacity, realizes the light keying of large steel translation door.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of upper hanging type sliding door load-bearing wheel group structure, it is characterized in that: it comprises wheel carrier, back shaft penetrates in the hole of wheel carrier upper end, bolster two ends symmetry BOGEY WHEEL is housed, the rolling surface of BOGEY WHEEL and the laminating of the inclined-plane of guide rail, be equipped with double-row self-aligning roller bearing in BOGEY WHEEL, capping is equipped with in BOGEY WHEEL outside, and wool felt dust ring is equipped with in inner side.
Described BOGEY WHEEL inner side arranges flange.
Described guide rail is that two channel-section steels that are arranged symmetrically with form.
Beneficial effect
The upper hanging type sliding door load-bearing wheel group structure that the utility model provides, the weight that can effectively decompose heavy parallel-moving type steel door, can significantly improve weight capacity, realizes the light keying of large steel translation door.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in Figure 1, a kind of upper hanging type sliding door load-bearing wheel group structure, it is characterized in that: it comprises wheel carrier 1, back shaft 2 penetrates in the hole of wheel carrier 1 upper end, bolster 2 two ends symmetries BOGEY WHEEL 3 is housed, the inclined-plane laminating of the rolling surface of BOGEY WHEEL 3 and guide rail 4, is equipped with double-row self-aligning roller bearing 5 in BOGEY WHEEL 3, capping 6 is equipped with in BOGEY WHEEL 3 outsides, and wool felt dust ring 7 is equipped with in inner side.
Described BOGEY WHEEL 3 inner sides arrange flange.
Described guide rail 4 is that two channel-section steels that are arranged symmetrically with form.
Two BOGEY WHEELs 3 of the present utility model are the two ends that symmetry is contained in bolster 2, thereby the rolling surface of two BOGEY WHEELs 3 has certain tapering and the inclined-plane of guide rail 4 to fit, and the axial thrust load of load can be cancelled each other, and has improved the force-bearing situation of guide rail 4.Guide rail 4 is bearing by BOGEY WHEEL 3 and is transmitting the load of coming; The flange of BOGEY WHEEL 3 wheels is stuck in guide rail 4 sides, makes BOGEY WHEEL 3 keep straight line moving along guide rail 4.The double-row self-aligning roller bearing 5 that is applicable to the lower work of heavy duty is housed in BOGEY WHEEL 3, and this bearing has aligning effect and can bear longitudinal and axial load simultaneously.
Capping 6 is equipped with in BOGEY WHEEL 3 outsides, and wool felt dust ring 7 is equipped with in inner side, prevents that dust and foreign material from entering bearing, can extend the application life of bearing.Wheel carrier 1 of the present utility model is connected with door leaf by bolt, and bolster 2 penetrates in the hole of wheel carrier 1 top, and door leaf weight acts directly on bolster 2 through wheel carrier hole, and bolster 2 is passed to guide rail by the rolling surface of bearing and BOGEY WHEEL 3 by load again.
The upper hanging type sliding door load-bearing wheel group structure that the utility model provides, the weight that can effectively decompose heavy parallel-moving type steel door, can significantly improve weight capacity, realizes the light keying of large steel translation door.
Claims (3)
