Background technology
For solving long girder temperature deformation problem, the girder span centre position of some Longspan Bridges between two middle towers is provided with stretching device, and the steel case beam inside of stretching device below need be provided with rigidity hinge structure.Existing rigidity hinge has the following disadvantages:
1, rigidity hinge rigidity
Conventional bearing generally adopts corrosion resistant plate and polytetrafluoroethylene (PTFE) slide plate couple friction pair, the bearing initial stage about 0.5mm in load gap, 50 years about 1.5～2mm of work abrasion loss, the gap that the bearing run duration produces is bigger, decay to rigidity hinge rigidity is big, need frequently regulate and eliminate the gap, regulate loaded down with trivial detailsly, the adjusting difficulty is big.
2, fulcrum horizontal plane unevenness influences bearing service life
⑴, be subjected to steel case beam foozle to influence (being difficult to avoid), the fulcrum plane that contacts with whole bearings often levelness differs greatly, this unevenness difference bearing can occur in slide plane " scraping " phenomenon, for conventional corrosion resistant plate and polytetrafluoroethylene (PTFE) slide plate (or polyethylene sliding plate) couple friction pair bearing, " metal and plastics macromolecular material " couple friction pair is difficult to resist this scraping phenomenon, the excessive wear of plastics macromolecular material often occurs, bearing is difficult to guarantee application life.
⑵, rotation are regulated to slide at each fulcrum sliding scale and be worked when being obstructed, and reply pivoting friction pair is carried out specialized designs, makes every effort to reduce rotating torque as far as possible, guarantees to regulate playing one's part to the full.
, after adopting the metallic rubbing pairs bearing, bearing initial stage running clearance is little, each fulcrum contact surface unevenness difference of the big or small case beam that in addition contacts with bearing can cause the hard contact phenomena of local fulcrum in slipping, also stuck phenomenon can occur what is more.
Therefore, developing a kind of novel rigid hinged-support as early as possible, to satisfy the stressed displacement requirement of rigidity hinge structure, guarantee the rigidity and the life requirements of rigidity hinge, is the useful mode that solves rigidity hinge conformation function demand.
The utility model content
The purpose of this utility model provides a kind of anti-hard contact, stuck rigid hinged support, and this bearing can be regulated and gap compensate for height and long service life automatically continuously, and has solved hard contact, stuck phenomenon.
The technical scheme that the utility model adopted is in order to achieve the above object: a kind of anti-hard contact, stuck rigid hinged support, comprise the upper bracket plate, plane stainless steel plate, brass, sphere corrosion resistant plate, concave surface liner plate, middle pressing plate and the lower support plate that set gradually from top to bottom, it is characterized in that: also be provided with the wedge shape regulating block between described concave surface liner plate and the middle pressing plate, described wedge shape regulating block termination is connected with adjusting nut by adjusting screw(rod) with the lower support plate termination, and also is provided with top pressure spring between wedge shape regulating block and the lower support plate.Be provided with the adjustment rubber pad between pressing plate and the lower support plate in the middle of described.
Also be provided with hold-down bolt on the pressing plate in the middle of described in the utility model.Described lower support plate lower end also is provided with connecting screw rod, and connecting screw rod is provided with packing ring and attaching nut.Also be provided with the brass sealing ring between described lower support plate and the middle pressing plate.
The utility model is adjusted rubber pad by setting up one, and this rubber pad can guarantee that bearing is not stuck by the compressive strain of self.And the utility model is simple in structure, easy to use to have certain economic benefits.

Among the figure: 1-upper bracket plate; 2-plane stainless steel plate; 3-brass; 4-sphere corrosion resistant plate; The 5-adjusting screw(rod); The 6-adjusting nut; The 7-top pressure spring; The 8-hold-down bolt; Pressing plate in the middle of the 9-; The 10-wedge shape is heightened piece; 11-concave surface liner plate; The 12-connecting screw rod; The 13-packing ring; 14-attaching nut; 15-brass sealing ring; 16-adjusts rubber pad; The 17-lower support plate.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further:
As shown in Figure 1, 2, anti-hard contact, stuck rigid hinged support comprise the upper bracket plate 1, plane stainless steel plate 2, brass 3, sphere corrosion resistant plate 4, concave surface liner plate 11, middle pressing plate 9 and the lower support plate 16 that set gradually from top to bottom.Also be provided with wedge shape regulating block 10 between described concave surface liner plate 11 and the middle pressing plate 9, described wedge shape regulating block 10 terminations are connected with adjusting nut 6 by adjusting screw(rod) 5 with lower support plate 16 terminations, and also are provided with top pressure spring 7 between wedge shape regulating block 10 and the lower support plate 16.Be provided with between pressing plate 9 and the lower support plate 17 in the middle of described and adjust rubber pad 16.Also be provided with hold-down bolt 8 on the pressing plate 9 in the middle of described.Lower support plate 16 lower ends also are provided with connecting screw rod 12, and connecting screw rod 12 is provided with packing ring 13 and attaching nut 14.Also be provided with brass sealing ring 15 between lower support plate 16 and the middle pressing plate 9.
Metallic rubbing pairs of the present utility model adopts copper radical self-lubricating materials and 38CrMoAl to carry out antithesis, has the characteristics of anti-bonding, anti-adhesive, high abrasion, corrosion-resistant and high-bearing capacity.
Owing to adopted metallic rubbing pairs, the abrasion gap that the bearing life period produces is little, more conventional corrosion resistant plate and the about 2mm of polytetrafluoroethylene (PTFE) slide plate (or polyethylene sliding plate) couple friction pair bearing gap reduction, the sudden change of " gap " problem and the phenomenon that takes place frequently do not appear, rigidity hinge rigidity its maintenance situation is good, and more can not produce conventional bearing influences the bearing key element in application life because of scraping.
Aforementioned copper radical self-lubricating slide plate base material is high-strength brass, self-lubricating property after the inlaid solid lubrication agent is good, guarantee in the bearing runtime long-acting lubricated, this kollag is embedded in the groove of high-strength brass, needs after inlaying with the high accuracy machining center frictional plane and sphere to be carried out Precision Machining.Mating material 38CrMoAl need carry out modified and nitriding is handled to improve material comprehensive mechanical performance and case hardness, after accurate grinding processing, can improve contact friction face fineness, guarantee that metallic rubbing pairs friction factor, abrasion resistance, fatigue resistance satisfy the requirement of rigid hinged support actual operating mode.
At the friction surface of concave surface liner plate, adopt moulding 38CrMoAl material, the surface of sphere of sphere is than higher after the moulding, and the finish of sheet material is also than higher simultaneously.
The utility model has adopted and has heightened continuously automatically and blank compensation apparatus in order to guarantee bearing rigidity in use.This device has the function of automatic lifting bearing superstructure position, but can't descend automatically.Therefore set up a rubber adjusting pad, this rubber pad does not influence the rigidity of bearing between the normal operating period at bearing.When hard contact and stuck phenomenon appearred in bearing, when promptly the actual compressive stress of bearing was greater than the design compressive stress, this rubber pad can guarantee that bearing is not stuck by the compressive strain of self.
