Specific embodiment
Bridge one-way support, including upper bracket plate 100, lower support plate 200 and the speed being arranged between two support plates
Lock 300.Wherein upper and lower support plate uses carbon steel steel plate, it is described in detail separately below.
Referring to figs. 1 to Fig. 8, the generally tabular of upper bracket plate 100 is fixed with connection in the upper surface of upper bracket plate 100
Part 000, the connector can be screw-thread steel column, and generally use nut is fixed in upper bracket plate or using other anchorings, weldering
The mode connect is fixed.Guide rail of a pair of symmetrically arranged section of setting for L-shaped, the guide rail in the lower surface of upper bracket plate 100
For straight line, the linear guide 110 is formed.It is respectively welded in the both sides of the linear guide 110 and fixes consolidating for speed lockup's device
Determine block 120, have the card slot there are one U-shaped in fixed block 120, which is used to be clamped the cylinder part of speed lockup's device.For reality
Now best fixed effect, using being bolted between fixed block and cylinder part.
Speed lockup's device 300, including cylinder body, piston, piston rod, cylinder cap and sealing element, wherein, it is in the present embodiment, living
Plug is located in cylinder body, and piston rod extends out from the both ends of cylinder body, is provided at both ends with screw thread in piston rod, is matched by screw thread
Conjunction is fixed in lower support plate, and cylinder interior is mounted in piston, and the both ends end of cylinder body using cylinder cap and sealing element into
Row sealing, forms one.There is through-hole in piston, the preferred taper hole of the through-hole is full of viscous material in the cavity of cylinder interior
Material, when piston is moved forward and backward, viscous material forms dynamic equilibrium, in piston by being redistributed after through-hole in piston both sides
During movement, speed control is realized.
Lower support plate 200, generally tabular are provided with the cunning coordinated with above-mentioned the linear guide in lower support plate 200
Block 210,210 section of sliding block is T-shaped, and in the utility model, on the surface of sliding block 210, there are two the identical grooves of structure for setting
220, which includes rectangle channel section 221 and arc channel section 222, and in rectangle channel section 221, there are one rectangles for tool
Roller installation space, a small amount of cylindrical roller 400 is installed in space, the cylindrical roller 400 preferentially select cylindrical roller, shape
Coordinate into rolling, the rotating direction of roller is with reference to figure 5 and Fig. 7, and the wherein quantity of roller is three, and rectangle channel section 221 is rolling
Five rollers can be accommodated on sub- rotating direction, that is, the quantity of roller will be less than rectangular channel sectional space, have abundant exercise
Space.Arc channel section is located at rectangle channel section both ends, and depth tapers into from inside to outside, that is, the arc channel section is deposited
A climbing radian is being upwardly formed in roller rolls side.
When upper and lower support plate relative motion, according to speed of related movement difference, cylindrical roller is in different states.
Situation one, with reference to figure 9a and Fig. 9 b, under normal circumstances, upper and lower support plate is micro relative motion, that is, the extension of bridge or
Person's retraction movement, under such state, rolling friction that the rolling of roller can have been formed, even if roller is rolled into rectangle channel section
Extreme position, upper and lower support plate can also be formed and be slidably matched, thus under such state, since speed of related movement is extremely slow, roller
Creeping formwork movement will not be being formed in arc groove section part.
Situation two, with reference to figure 9c to Fig. 9 e, when an earthquake occurs or bridge is when seriously the event of toppling tends to occur, on
Strenuous exercise between lower support plate, speed are tens thousand of times under normal service state, the speed control between upper and lower support plate
Device can only play part damping action, the jerky motion between upper lower support plate so that roller is climbed in the formation of arc groove section part
Mould move, climbing roller as a result, roller is locked in arc slot space between lower support plate, by skew force
Effect forms chock locking phenomenon so that upper lower support plate is locked, and prevents the cooperation between lower support plate from failing, when anti-
After force, counter motion between upper lower support plate can be locked by the roller of opposite side after extreme position is moved to, form wedge
Son locking phenomenon.
Situation three, between situation one and situation two, speed lockup's device plays mainly the speed between upper and lower support plate
Speed lockup's effect, and the reasonable employment section of speed lockup's device is located within the situation operating mode.
Further, position limiting structure is set between fixed block and lower support plate, which includes being fixed on undersetting
Limited block 230 on plate and the limiting section 121 extended downwardly from upper bracket plate fixed block 120.
Further, annular knurl processing 500 or wharf's pavement quality will be done at the horizontal plane cooperation of sliding block and the linear guide, is matched
The locking effect of roller is closed, locking effect is more preferable, and speed lockup is realized by the locking of sliding block and the linear guide at horizontal plane.
Embodiment two
As further improved procedure, the material of the cylindrical roller in each groove is different, wherein, positioned at both sides
And the cylindrical roller contacted with arc channel section that takes the lead in, using ceramic material, intermediate roller is steel material or copper alloy material
Matter, during ceramic cylinder roller is contacted with arc groove face, ceramic cylinder roller can crush at lozenges, crush
Afterwards, disintegrating slag either ceramic clast and then the remaining steel material of raising or alloy cylindrical roller and upper undersetting are formed in groove
Between frictional force, can preferably consume energy.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality
Novel range is defined, and under the premise of the spirit of the design of the utility model is not departed from, relevant technical staff in the field is to this
The various modifications of utility model and improvement, should all be determined by the utility model claims book in protection domain.
