Abstract
The utility model discloses a kind of rail in high speed railway welding point and reinforces equipment, including bottom plate, and the bottom plate is arranged on the lower end of rail, and bottom plate is fixed by bolt with base；Base is arranged on the both sides of rail；It is glued to be glued insulating barrier on the inside of clamping plate, the splicing insulating barrier at the web of the rail of the rail both sides at steel rail weld joint with abutting；It is glued on the outside of clamping plate and is abutted with screwing in the top of the screw rod in base screw.The utility model has the advantages that：Reinforce steel rail weld joint and be not required to drilling；Splicing clamping plate for reinforcing is integrally formed with the rail at welding point；It is glued stiction between the rail at clamping plate and welding point to significantly increase；Rigidity and intensity at steel rail weld joint are effectively improved：The insulating properties reinforced between equipment and rail are good.
Description
Technical field
The utility model belongs to high speed railway track gapless track technical field, more particularly to a kind of rail in high speed railway welding
Joint reinforces equipment.
Background technology
Railroad track gapless track is the important equipment of high-speed railway, and steel rail weld joint is gapless track emphasis maintenance
Key position, is that the steel rail weld joint of pre- tetrandra root hurt occurs fracture and ensures the safety of steel rail weld joint, generally uses
Steel rail weld joint is reinforced to bolt the method for bulge clamping plate, at present, the side of bulge clamping plate reinforcement steel rail weld joint is bolted
Shortcoming present in method is：Reinforcing steel rail weld joint need to drill on rail, and borehole accuracy is coarse easily stress concentration occurs；
Bolt bulge clamping plate, not into being integral, bolts quiet between bulge clamping plate and welding point rail rub not with the rail at welding point
Wiping power is smaller, and the integral rigidity and intensity of steel rail weld joint are not effectively improved；Enhancing resistance vertical and horizontal shearing
The effect of power is not obvious enough.
The content of the invention
The purpose of this utility model is the shortcoming according to present in above-mentioned bolt bulge clamping plate reinforcement steel rail weld joint, is carried
Equipment is reinforced for a kind of rail in high speed railway welding point.
The purpose of this utility model is completed by following technical scheme：
A kind of rail in high speed railway welding point reinforces equipment, including bottom plate, and the bottom plate is arranged on the lower end of rail, bottom
Plate is fixed by bolt with base；Base is arranged on the both sides of rail；It is glued to be glued insulating barrier on the inside of clamping plate, the splicing is exhausted
Edge layer at the web of the rail of the rail both sides at steel rail weld joint with abutting；It is glued on the outside of clamping plate with screwing in the screw rod in base screw
Top abut；Also include clamp, the clamp is fixed on screw rod；The base, bottom plate and rail junction are respectively provided with absolutely
Edge layer.
The utility model rail in high speed railway welding point reinforce equipment advantage be：Steel rail weld joint is reinforced to be not required to bore
Hole；Splicing clamping plate for reinforcing is integrally formed with the rail at welding point；It is glued between the rail at clamping plate and welding point
Stiction is significantly increased；Rigidity and intensity at steel rail weld joint are effectively improved：Reinforce between equipment and rail
Insulating properties are good.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model rail in high speed railway welding point reinforces equipment.
In figure：1 is rail, and 2 is are glued insulating barrier, and 3 is are glued clamping plate, and 4 be screw rod, and 5 be clamp, and 6 be base, and 7 be bottom
Plate, 8 be felt pad, and 9 be bolt, and 10 be packing ring.
Embodiment
Technical characteristic of the present utility model is described in further detail by embodiment with reference to accompanying drawing, as shown in figure 1, will
Bonding agent is applied to the splicing insulating barrier 2 of the web of the rail and splicing clamping plate 3 of the both sides of rail 1 through polishing derusting at the welding point of rail 1,
Clamping plate 3 will be glued to be symmetrically mounted on the both sides web of the rail of rail 1 at the welding point of rail 1, base 6 is passed through into bolt 9 and packing ring
10 are bolted with one end of bottom plate 7, and the other end of bottom plate 7 is passed through through the flange of rail of rail 1 and passes through bolt 9 and pad with another base 6
Circle 10 is bolted, by felt pad 8 be placed between bottom plate 7 and the flange of rail of rail 1 and horizontal base 6 pressure tongue between the rail limb of rail 1,
Rotary screw 4 simultaneously applies top pressure intensifying force by the turret head top of screw rod 4 to being glued clamping plate 3, continues rotary screw 4 and meets splicing
Clamping plate 3 and rail 1 be glued needed for pressure and ensure to reinforce the clamping force of equipment, clamp 5 is placed in the hexagonal top of screw rod 4 with crouching
Between formula base 6, keep reinforcing the clamping force of equipment, prevent that 2-4 sets are installed at the decline of clamping force, each steel rail weld joint
Top pressure clamping device, often covers top pressure clamping device and is provided with single or double formula horizontal mechanical spiral top, often cover on top pressure clamping device
The clamping force of top pressure clamping device provided with double type horizontal mechanical spiral top is, more than 420KN, often to cover and set on top pressure clamping device
The clamping force for having the top pressure clamping device of double type horizontal mechanical spiral top is, more than 840KN, to make at splicing clamping plate 3 and welding point
Rail 1 be integrally formed, realize and reinforce the target reinforced to rail in high speed railway welding point of equipment.
Described is glued clamping plate to strengthen tunneling boring metal splint and thermosetting in the splicing on enhancing tunneling boring metal splint
Insulating barrier.
Described bonding agent is low temperature curing type adhesive and room temperature curing type adhesive.
Described bottom plate is concave base plate, and the two ends of concave base plate are provided with screw.
Described bolt and packing ring are high-strength bolt and spring washer.
Described felt pad is fiberglass resin felt pad and enhancing nylon felt pad.
Described clamp is wedge-shaped clamp, L-shaped clamp, groove profile clamp.
Above-described embodiment is merely to illustrate the application, rather than the restriction to the present utility model application, as long as new in this practicality
The utility model claims are fallen within to change, the deformation of embodiment described above in type application spirit
In the range of.
