Description

Novel protection warning fence for shunting nose of expressway ramp

Technical Field

The utility model relates to a set up on highway buffer stop, mainly used highway ramp's reposition of redundant personnel nose, have maintain convenient, absorb buffering, durable, characteristics that part interchangeability is strong, reuse rate is high.

Background

The anti-collision block and the anti-collision barrel are facilities for safely stopping a vehicle by absorbing collision energy of the vehicle and changing the driving direction of the vehicle to avoid serious injury to passengers, and have the main functions of reducing the severity of accidents and warning and inducing through surface colors and graphic symbols. The utility model discloses a ramp reposition of redundant personnel nose protection warning fence have more advantage, have the significance to the use of product and cost of maintenance's reduction.

At present, conventionally used anti-collision blocks and anti-collision columns generally have the defects of easy collision to generate secondary displacement, secondary accidents are caused, the anti-collision blocks and the anti-collision columns are easy to damage, a part of damaged parts often need to be integrally replaced, finally, the maintenance, use and replacement efficiency is low, and the requirements of daily quick disassembly and assembly and quick maintenance are difficult to meet.

The utility model provides an above-mentioned problem, refer to and adopt the current interior surrounding panel, stand, the pre-buried flange sleeve pipe that reach national standard, through stand, trapezoidal internal and external bracing, pre-buried flange sleeve pipe's design improvement, constitute a neotype ramp reposition of redundant personnel nose protection warning fence.

SUMMERY OF THE UTILITY MODEL

The design scheme of the utility model is as follows: improve on current anticollision post basis and design out a neotype circle way reposition of redundant personnel nose protection warning fence, including interior surrounding, outer surrounding, joint combination, stand, pre-buried flange sleeve pipe, trapezoidal interior outer support, stand pass through the bolt and be connected the fastening with two inside and outside encircles, and it is intraductal that the pre-buried flange sleeve is inserted to the bottom, and interior outer support is fixed through bolted connection with inside and outside surrounding.

The inner/outer enclosure is formed by rolling a steel plate, a plurality of through holes for connection are processed on the surface of the steel plate, and the rolling is in a certain radian;

the joint combination is formed by cutting and bending a steel plate and is used for being connected with the inner and outer enclosures and the upright post combination;

the upright post is formed by processing a steel pipe, an opening at the upper end is used for being connected with the sleeve and connected with the surrounding assembly, and the lower end of the upright post is sleeved at the bottom of the embedded flange sleeve;

the embedded flange sleeve is formed by welding a circular pipe and a flange plate, the number of the steel pipes and the number of the flange plates correspond to that of the stand columns, each stand column is correspondingly inserted into the embedded flange sleeve, the flange end is positioned on a ground surface during embedding, and cement at the other end is embedded into a foundation;

the trapezoidal inner and outer support is formed by cutting and bending a steel plate, is of a trapezoidal structure, and is connected with the inner/outer enclosure to form a main energy absorption structure of the guardrail.

The warning label comprises 1-inner surrounding, 2-outer surrounding, 3-joint combination, 4-upright post, 5-embedded flange sleeve, 6-trapezoidal inner support, 7-trapezoidal outer support and 8-warning label.

Detailed Description

The invention will be further explained with reference to the following description and drawings

Example (b): the utility model provides a novel protection of high-speed ring road reposition of redundant personnel nose warning fence, surround in including, outer, connect the combination, a column, pre-buried flange sleeve pipe, trapezoidal internal and external bracing, the stand passes through bolt and two internal and external encirclements fastening of being connected, bottom and pre-buried flange bushing, trapezoidal internal and external bracing is fixed through bolted connection with internal and external encirclement, as shown in figure 1, each subassembly is connected the fastening with each subassembly with the bolt respectively according to the order of drawing, as shown in figure 2, internal/external enclosure is respectively with internal and external for the bolted connection fastening, then the internal and external end is connected through the joint subassembly, accomplish holistic main body frame assembly, can paste warning sign increase and protect warning effect outside surrounding one side.

As shown in fig. 1, 2, this novel protection of ramp reposition of redundant personnel nose warning fence compares ordinary rail guard, pre-buried sleeve pipe and stand have been increased, trapezoidal support bearing structure, when the reinforcing energy-absorbing, effectively prevent to protect producing the secondary displacement after hitting of warning fence, reduce secondary accident probability, the bolt is dismantled and has been reduced the installation degree of difficulty, it is very convenient to dismantle simultaneously, only need unpack apart the bolt of stand and just can directly unpack apart one section guardrail, can directly wholly change upper end guardrail subassembly after the damage, pre-buried sleeve pipe subassembly can reuse, a large amount of maintenance costs have also been saved.

As shown in figure 4, the upright post is provided with a mounting hole, and a single bolt connecting structure is adopted, so that quick replacement can be realized under special conditions.

As shown in fig. 5, compared with the existing embedded pipe, the embedded flange sleeve pipe is added with a flange structure, so that the impact resistance of the embedded pipe can be greatly enhanced, and the ground can be protected from being damaged by impact.
