Problems solved by technology

Flyover guardrails are generally made of brackets, steel pipes and other materials. Because the flyover has a bend in the downlink, the steel pipes used to build the bridge guardrail will have corners. After the steel pipes are bent, they will be welded to form a smooth arc transition. Different positions require different bending angles of steel pipes. Existing steel pipes cannot effectively meet the requirements of use and have poor adaptability

Embodiment 1

[0055] See Figure 1-10 , A new type of steel pipe in the corner of the bridge, including the telescopic steel pipe 2, the outer end of the telescopic steel pipe 2, and the extended outer tube 1 that matches thereof, and the inner end of the telescopic steel pipe 2 is connected to the curved assembly 3, telescopic. The upper ends of the steel pipe 2 are fixedly connected to the sealing sleeve 4, and the outer end of the sealing sleeve 4 is rotated and connected to the back-side curved assembly 3, and the rear side bending assembly 3 is connected to the adjustment assembly 6, located at the front side curved assembly 3 left end connection Line component 7; see figure 1 , Figure 5 with Figure 6 The curved assembly 3 includes a curved longboard 301, and a plurality of curved longboard 301 are connected to the front and rear two inner walls of the telescopic steel pipe 2, and the curved blade 301 is fixedly connected to the left side of the curved blade 302, and the curved long plat...

Embodiment 2

[0066] See Figure 1-10 The same or corresponding components as in Example 1 employ reference numerals corresponding to Embodiment 1, which is simply, and the difference points from Example 1 are described below. This Example 2 differs from the first embodiment in that: see Figure 9 The method of use of adjustment assembly 6 is as follows:

[0067] S1. Rotate the locking bolt, so that the adjustment cap 604 can be rotated within the sealing sleeve 4;

[0068] S2. Based by using the rotating tool to match the word long groove, the adjustment cap 604 is rotated, by adjusting the rod 603 and the adjustment turn rod 602 to rotate, the winding shaft 601 is constantly tightening the guide steel cable 304;

[0069] S3. Guided steel cable 304 is constantly tightening, driving between plurality of curved longboard 301 to generate curvature, resulting in a corresponding bending of the telescopic steel pipe 2 and the extension outer tube 1;

[0070] S4. After completing the curvature, stop t...

Embodiment 3

[0072] See Figure 1-10 The same or corresponding components as in Example 1 employ reference numerals corresponding to Embodiment 1, which is simply, and the difference points from Example 1 are described below. This Example 3 differs from the first embodiment in that: see Figure 10 The method of use of the wire assembly 7 is:

[0073] S1. By rotating the turning plate 704, the stop bolt 702 is rotated from the chute, so that the loose wire shaft 701 can be rotated within the sealing sleeve 4;

[0074] When the adjustment assembly 6 is tightened, the extension outer tube 1 and the telescopic steel pipe 2 bend toward the adjustment assembly 6 side, and the guide steel cable 304 is wrapped with the patent hierarchy 701, and the steel cable 304 can drive the loop shaft 701 rotates so that the guide steel cable around the loose shaft 701 is constantly loosen;

[0075] After completing the bend, the turning turning plate 704 threads the stop bolt 702 and the loose wire shaft 701, and ...

Abstract

The invention discloses a novel steel pipe for the corner of a bridge guardrail, and belongs to the field of pipes. The novel steel pipe for the corner of the bridge guardrail comprises a telescopic steel pipe, the outer end of the telescopic steel pipe is sleeved with an extension outer layer pipe matched with the telescopic steel pipe, and the inner end of the telescopic steel pipe is connectedwith a pair of bending components matched with the telescopic steel pipe. Sealing sleeves are fixedly connected to the left end and the right end of the telescopic steel pipe correspondingly, the outer ends of the sealing sleeves are rotationally connected with through connection threaded sleeves, and an adjusting assembly is connected to the left end of the bending assembly located on the rear side. A bending assembly is arranged at the inner side of the telescopic steel pipe, the bending degree of the bending assembly is adjusted through the adjusting assembly and a feeding assembly, the bending range of the telescopic steel pipe is conveniently controlled, the requirements of overpass guardrail corners of different specifications are met, and the applicability is improved; and and the service life of the overpass guardrail corners is effectively prolonged while the attractiveness of the guardrail is guaranteed through effective cooperation of the extension outer layer pipe and the telescopic steel pipe.

Description

Technical field [0001] The present invention relates to the field of pipes, and more particularly to a new steel pipe for a bridge guard corner. Background technique [0002] The bridge guardrail refers to the guardrail set on the bridge. Its purpose is to prevent the failure of the vehicle from crossing the bridge, with the function of causing the vehicle to break through, wear, over the bridge, and beautify the bridge building. The type method of dividing the bridge guardrail is much, in addition to setting the location, it can also be divided according to the structural characteristics, anti-collision performance. According to the setting position, it can be divided into a bridge side guardrail, the central separation of the bridge and the guidelines, the lane boundaries of the lane; can be divided into beam column (metal-metal and concrete) guardrails, reinforced concrete wall expansions and combined guardrails. The anti-collision performance can be divided into a rigid guard...
