Its further technical scheme is: described elastic device or for steel spring or for polyurethane spring or for the rubber bodies spring.
Owing to have following beneficial effect to shift comb tooth plate stretching device more than the employing technique scheme, the utility model:
1. this stretching device is at swing tooth plate end design of hinges rotating shaft mechanism and tooth plate pre-tightening mechanism, when the beam body was subjected to the repeated stock of wheel weight and beam-ends to produce the multi-directional deflection such as vertical, horizontal, oblique, stretching device can be realized multi-directional deflection by the hinge rotating shaft mechanism; And the tooth plate pre-tightening mechanism is by running through the anchor bolt elasticity of compression device of elastic device, swing tooth plate is carried out flexible anchoring, guarantee that the unyielding damage of anchor bolt, swing tooth plate do not get loose, stretching device does not damage, after the external force of the multiple-directional rotating such as vertical, horizontal, oblique of swing tooth plate disappeared, elastic device can make swing tooth plate automatically reset.
This stretching device have driving steadily, low, the construction of noise and advantage easy to maintenance, it need to not go repair and replacement in the situation of totally-enclosed traffic, maintenance cost is lower.
Below in conjunction with drawings and Examples the technical characterictic to shift comb tooth plate stretching device more than the utility model is further described.
