It is widely applied in the longspan structures such as hydraulic piping.When especially design according to simply supported beam, setting roller support can discharge
Fall the horizontal force that structure passes to support, reduces project cost.
The quality of roller support working performance depends on the rolling friction performance of roller bearing.Therefore, the invention reside in solve one
Frictional force small roller support device when the suitable angle of displacement range ability of kind, roller bearing roll.
Summary of the invention
For the deficiencies in the prior art, the utility model, which provides one kind, to be had limit, rolls flexible roller support
Device.The technical solution adopted in the utility model is:
A kind of roller support device, including roller bearing, roller stick, base-plate, lower dental lamina, upper dental lamina, lower limiting board, upper limit
Plate, support top plate；
The roller bearing is arranged between base-plate and support top plate；
Upper dental lamina and lower dental lamina are respectively equipped in the two sides of roller bearing；Upper dental lamina is connected to support top plate, and lower dental lamina is connected to
Base-plate；The corresponding oval hole slot of transverse direction is provided on upper dental lamina and lower dental lamina；The inner end of roller stick is connect with roller bearing, and outer end is inserted
In the oval hole slot for entering upper dental lamina and lower dental lamina；
Support top plate and base-plate are located above and below roller bearing；
Upper limit plate is connected on support top plate, and lower limiting board is connected on base-plate, and roller bearing circumferential surface is equipped with annular
Slot, upper limit plate and lower limiting board correspond to the annular groove location on roller bearing.
Further, upper dental lamina is located at the outside of lower dental lamina, and the lower edge of upper dental lamina is lower than the top edge of lower dental lamina.
Further, the base-plate surface under roller bearing is equipped with antifriction material.
Further, roller surface is round and smooth, and roller bearing both ends are respectively equipped with reversed cone angle.
Further, support embedded board is welded with below base-plate.
Further, superstructure support plate is welded with above support top plate.
Utility model has the advantages that
1) wanted by the rotation of roller bearing come the displacement of commensurate structure, the quantity of roller bearing according to the size of horizontal thrust and
It is fixed.
2) open loop connected in star in the middle part of roller bearing adds limit plate, guarantee roller bearing roll without departing from；Support bottom under roller bearing simultaneously
Plate has certain rigidity, to guarantee the smooth of base-plate.
3) the lateral slotted hole on upper and lower dental lamina can limit the maximum displacement of roller bearing.
Detailed description of the invention
Fig. 1 is the structure composition schematic diagram of the utility model.
Fig. 2 is the side schematic view of the utility model.
Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
A kind of roller support device (hereinafter referred to as support) provided by the utility model, as shown in Figure 1 and Figure 2, including roller bearing
1, roller stick 2, base-plate 3, lower dental lamina 4, upper dental lamina 5, lower limiting board 6, upper limit plate 7, support top plate 8；
The roller bearing 1 is arranged between base-plate 3 and support top plate 8；Roller bearing 1 is the most heavy of realization support locomotive function
Component is wanted, the quantity of roller bearing 1 is depending on the size of horizontal thrust, such as 1 or 2 or more；
For the flexibility for guaranteeing roller bearing rotation, 1 surface of roller bearing should process round and smooth, and 1 both ends of roller bearing are respectively equipped with reversed cone angle,
To reduce frictional force when roller bearing 1 rolls；When structure level thrust is larger, can be arranged on 3 surface of base-plate under roller bearing 1
Antifriction material, such as polytetrafluoroethylplastic plastic is pasted, it is further reduced frictional force when roller bearing rolls；
Upper dental lamina 5 and lower dental lamina 4 are respectively equipped in the two sides of roller bearing 1；Upper dental lamina 5 is connected to support top plate 8, lower dental lamina 4
It is connected to base-plate 3；The corresponding oval hole slot 4a of transverse direction is provided on upper dental lamina 5 and lower dental lamina 4；The inner end of roller stick 2 and rolling
Axis 1 by being welded to connect, be inserted into the oval hole slot 4a of upper dental lamina 5 and lower dental lamina 4 by outer end；Roller stick 2 is rotated together with roller bearing 1；
The length of oval hole slot 4a is determined according to the displacement structure angle under the effect of main structure rarely occurred earthquake；Oval hole slot 4a can limit rolling
The displacement range of axis 1；
More preferably, upper dental lamina 5 is located at the outside of lower dental lamina 4, and the lower edge of upper dental lamina 5 is lower than the top edge of lower dental lamina 4,
It can prevent rainwater from entering in support well, it is not flexible to avoid the rotation of support internal corrosion；
