Embodiment Construction

[0038] The present invention is described in detail below in conjunction with accompanying drawing:

[0039] combine Figure 1-Figure 2 , The present invention provides a guardrail height raising device, comprising: an inner casing 1, a mounting frame 2, and a rack and pinion transmission system; wherein, the rack and pinion transmission system includes: a gear 3, a rack 4, and a gear transmission member 5. The specific structure of the guardrail height raising device is introduced as follows:

[0040] (1) Inner sleeve and mounting frame

[0041] The top of the inner casing 1 is used for fixed connection with the guardrail 7;

[0042] The mounting frame 2 is fixedly installed under the inner casing 1; the outer diameters of the mounting frame 2 and the inner casing 1 are both smaller than the cavity diameter of the column 6; the mounting frame 2 is placed in the cavity of the column 6.

[0043] In practice, refer to image 3 , the specific structure of the mounting frame 2...

Abstract

The invention provides a guardrail height increasing device and method. The guardrail height increasing device comprises an inner sleeve (1), an installing rack (2) and a gear-rack transmission system, the gear-rack transmission system comprises a gear (3), a rack (4) and a gear transmission part (5), the gear transmission part (5) comprises a transmission rod (5-1), a first fastener (5-2) and a second fastener (5-3). The guardrail height increasing device has the advantages that compared with a common guardrail height increasing device, the guardrail height can be adjusted at will, and the defects that the existing guardrail height increasing device needs punching holes again and reserving holes are overcome; guardrail height increase is not limited, the height can be increased by using a special spanner for screwing, and the increasing accuracy can reach the millimeter level; the guardrail height increasing device is suitable for guardrails at different guard levels and beams in different shapes and capable of meeting the requirement for guardrail height increase of road pavement overlay.

Description

technical field [0001] The invention belongs to the technical field of highway safety facilities, and in particular relates to a guardrail height raising device and a guardrail height raising method. Background technique [0002] The anti-collision barrier is one of the most important traffic infrastructures of the highway, and it is an important maintenance and safety guarantee facility for the highway. The main function of the anti-collision guardrail is to directly bear the impact force of the vehicle when an accident occurs while driving on the road, and to protect the vehicle from overturning the guardrail and causing greater losses in the event of an accident. [0003] At present, with the rapid development of expressway construction in my country, many road sections that have been built in advance can no longer meet the needs of the current large traffic volume due to reasons such as low design standards, and are facing problems such as reconstruction, expansion, and ...
