The anti-blocking device of the road guard rail has the following defects: 1. a single-point supporting structure connected by a single resistance piece is adopted between each upright post and the guardrail plate, so that the stress is concentrated too much, the guardrail structure is not stable enough, and the fixing bolt for connecting the resistance piece and the upright post is also easy to break; the stress of the guardrail can not be uniformly dispersed when the guardrail is collided, and the guardrail plate is easy to deform, roll and crack; 2. the anti-blocking piece is only provided with a first-level buffer structure, the energy absorption, the buffering and the anti-collision performance of the anti-blocking piece are poor, the first-level buffer design is hard for small vehicles, and the first-level buffer design is soft for large vehicles, so that good protection can not be provided for drivers and passengers of various vehicle types, and the safety protection performance is insufficient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a piece is prevented hindering in buffering that highway rail guard supports more, this kind of many supports buffering and prevents hindering the piece and can solve current highway guardrail and prevent that there is the atress too concentrated, the relatively poor problem of shock-absorbing capacity.

In order to solve the above problem, the utility model discloses a technical scheme is: the multi-support buffering anti-blocking piece of the road guardrail comprises an anti-blocking piece main body connected between a stand column and a guardrail plate, wherein the anti-blocking piece main body is fixedly connected with a connecting reinforcing plate and is connected with the guardrail plate through the connecting reinforcing plate; the connection reinforcing plate is connected with at least two anti-blocking part main bodies, and the anti-blocking part main bodies are arranged at intervals along the axial direction of the stand column.

In the technical solution of the multiple supporting buffering anti-blocking members of the road guard rail, a more specific technical solution may also be: the surface of the connecting reinforcing plate is attached to the back surface of the guardrail plate.

Furthermore, prevent hindering the piece main part and include that at least two connect gradually in the stand with connect the cushion collar between the reinforcing plate, adjacent two cushion collar radially fixed connection, by the stand towards connect the reinforcing plate direction setting each the through-hole sectional area of cushion collar reduces gradually.

Furthermore, the height of each buffer sleeve arranged from the upright column to the direction of the connecting reinforcing plate is gradually reduced.

Furthermore, two sides of the buffer sleeve are protruded towards the direction of deviating from.

Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has:

1. the connection reinforcing plate is arranged to connect a plurality of anti-blocking main bodies, so that multipoint support is formed between the guardrail plate and the stand column, the stress is dispersed, the energy absorption and buffering performance of the guardrail are improved, the strength and stability of the guardrail are improved, passengers are protected, the damage to vehicles is reduced, and the safety protection performance of the highway guardrail is enhanced.

2. The surface of the connecting reinforcing plate is attached to the guardrail plate, so that the strength and the stability of the guardrail can be improved.

3. Prevent hindering a main part and set up to multistage buffer structure, and the through-hole sectional area of buffer sleeve at different levels reduces towards connection reinforcing plate one side by the stand gradually to can both provide suitable buffering dynamics to the vehicle of different specifications such as dolly, cart, obtain good protection.

4. The height of the buffer sleeve and the protruding structural design of the two sides can optimize the energy absorption, buffering and anti-collision performance of the guardrail.

Detailed Description

The invention will be described in more detail with reference to the following embodiments:

the multi-support buffering anti-blocking member of the road guardrail shown in fig. 1 to 3 mainly comprises an anti-blocking member main body 1 and a connecting reinforcing plate 2, wherein the connecting reinforcing plate 2 is fixedly connected with the plurality of anti-blocking member main bodies 1 in a welding or bolt connection mode, the connecting reinforcing plate 2 of the embodiment is a corrugated plate with the same cross section shape as that of the corrugated guardrail plate, and the surface of the connecting reinforcing plate 2 is attached to the back surface of the guardrail plate; the corrugated guardrail plate is provided with connecting reinforcing plates 2 at positions corresponding to the stand columns, the stand columns are fixedly connected with three anti-blocking piece main bodies 1 which are arranged at intervals along the axial direction of the stand columns, and the anti-blocking piece main bodies 1 are fixedly connected with the corrugated guardrail plate through the connecting reinforcing plates 2; each stopper body 1 is fixed to the back side of the connection reinforcing plate 2 opposite to the convex portion. The main body 1 of the anti-blocking part of the embodiment is of a two-stage buffer structure and comprises a first-stage buffer sleeve 1-1 and a second-stage buffer sleeve 1-2 which are sequentially connected towards the direction of an upright column by a connection reinforcing plate 2, wherein the first-stage buffer sleeve 1-1 and the second-stage buffer sleeve 1-2 are fixedly connected in the radial direction, and the connection parts of the first-stage buffer sleeve 1-1 and the second-stage buffer sleeve 1-2 are fixed by; the first-stage buffer sleeve 1-1 and the second-stage buffer sleeve 1-2 are hexagonal sleeve bodies, two sides of each sleeve body protrude outwards in the direction of departure, and arcs at corners are in transition to avoid stress concentration. In order to ensure that both a trolley and a cart can obtain good buffer protection, the sectional area of the through hole of the first-stage buffer sleeve 1-1 is smaller than that of the through hole of the second-stage buffer sleeve 1-2, and the height of the first-stage buffer sleeve 1-1 is smaller than that of the second-stage buffer sleeve 1-2.

This many supports of highway rail guard buffering and prevents hindering piece is that the multiple spot supports and multistage buffering prevents hindering the structure, and when the vehicle collided the guardrail, the impact force via the guardrail board, connect reinforcing plate 2 and a plurality of prevent hindering a main part 1 dispersion, the fixing bolt who connects and prevent hindering a main part 1 and stand was difficult to be broken by the collision, and the guardrail also is difficult to deform and damage. When the trolley forms larger impact force to the guardrail, the first-stage buffer sleeve 1-1 of the anti-blocking part main body 1 flattens and absorbs energy, impact force is rapidly dispersed, and the trolley and passengers are not injured due to over hardness. When a large vehicle forms large impact force on the guardrail, the primary buffer sleeve 1-1 and the secondary buffer sleeve 1-2 of the anti-blocking part main body 1 are sequentially flattened for absorbing energy, and the impact force is rapidly dispersed, so that the large vehicle and passengers are well protected.
