Abstract
The utility model discloses a bridge antislip telescoping device aims to solve serious slipping appeared when the vehicles pass the bridge telescoping device, and technical proposal is that an antislip sagging lines are arranged on the shaped steel surfaces of the telescoping device, saying the contact surface with the wheels. The antislip telescoping device can effectively increase friction force and avoid slipping when the vehicles pass the bridge telescoping device.
Description
Technical field:
The utility model relates to a kind of bridge extension joint.
Background technology:
Various types of stretching devices that China uses at present generally lack when designing considers the anti-skid structure design of vehicle when passing through, and anti-skidding problem especially seems even more important at big displacement stretching device on the stretching device of northern China use in winter.
Existing bridge extension joint is when vehicle passes through, the main frictional force on vehicle and shaped steel surface that relies on is anti-skidding, but smooth shaped steel surface and the friction factor between the wheel are less, and its contact surface is more smooth after the long-term and wheel effect when stretching device shaped steel, frictional force between them will be littler also, and this will more be unfavorable for the anti-skidding of vehicle.Especially when the telescopic displacement amount was big, shaped steel quantity was more, and the skidding of vehicle by stretching device the time is even more serious.
Summary of the invention:
The utility model is intended to solve the comparatively serious skidding that vehicle occurs by bridge extension joint the time, provides a kind of bridge anti-skidding stretching device, this anti-skidding stretching device can effectively play increases frictional force, prevent vehicle by the time produce and skid.
The purpose of this utility model realizes by implementing following technical proposals:
The anti-skidding stretching device of a kind of bridge comprises shaped steel, it is characterized in that: there is anti-skidding lines on the shaped steel surface.
Anti-skidding lines described in the utility model is that bar shaped is unidirectional or intersect protruding lines.
Anti-skidding lines described in the utility model is for being interrupted unidirectional or intersecting protruding lines.
The lug boss of intermittent bosses lines described in the utility model is the low middle high arc strips in both sides.
Advantage of the present utility model is: owing to set up ridge design on the shaped steel surface, increased friction factor, can stop vehicle and stretching device to produce relative displacement (promptly skidding), and manufacture craft is simple, good looking appearance.
Stressed schematic diagram Fig. 2 of wheel when description of drawings: Fig. 1 passes through stretching device for vehicle is two kinds of preferable shaped steel non skid matting patterns of the utility model skidproof effect
The specific embodiment:
The anti-skidding stretching device of a kind of bridge comprises shaped steel 1, and there is anti-skidding lines 2,3 on the shaped steel surface.Anti-skidding lines for intersect protruding lines 2 and being interrupted when intersecting protruding lines 3 effect preferable.
The lug boss of described intermittent bosses lines 3 is the low middle high arc strips in both sides.
Claims (4)
1, the anti-skidding stretching device of a kind of bridge comprises shaped steel (1), it is characterized in that: there is anti-skidding lines (2,3) on shaped steel (1) surface.
2, the anti-skidding stretching device of bridge according to claim 1 is characterized in that: described anti-skidding lines is that bar shaped is unidirectional or intersect protruding lines (2).
3, the anti-skidding stretching device of bridge according to claim 1 is characterized in that: described anti-skidding lines is for being interrupted unidirectional or intersecting protruding lines (3).
4, according to claim 1 or the anti-skidding stretching device of 3 described bridges, it is characterized in that: the lug boss of described intermittent bosses lines (3) is the low middle high arc strips in both sides.
