Description
Technical field
The invention mainly relates to civil engineering correlative technology field, specifically a kind of urban road safety height-limiting device.
Background technique
Height limiter is mounted on urban road, is mainly used for protecting road, bridge etc., is prevented excessively high vehicle from entering
To limit for height section.Two columns, one height-limiting bar composition gantry type frame structure is usually used in the height limiter of traditional structure,
Column is embedded to underground or fixes the limit for height of realization vehicle on the ground.Traditional height limiter be easy to cause accident when in use,
When the driver that drives a vehicle does not notice height limiter or estimates mistake to height-limiting bar or height of car, easily lead to column and limit for height
Collapsing, tilting for bar, be easy to cause traffic accident.
To solve the above-mentioned problems, there is also some limit for height dresses that can play certain warning function in the prior art
It sets, caution structure mainly has several forms such as jingle bell, sounding, light warning, and related warning can be triggered when vehicle is forced through
Structure carries out early warning to driver, but the success rate in traditional structure using the methods of sounding is lower, is made an uproar by vehicle interior and outside
The image of sound, general driver are difficult to be reacted to such alarm in time.And for the intelligent alarms structure such as some sounding, light, at
This height, high failure rate need to carry out periodic maintenance, and the human and material resources of investment are larger, and practicability is extremely low.
Summary of the invention
For the deficiency for solving current technology, the present invention combination prior art provides a kind of city road from practical application
Road safety height-limiting device, this height limiter has purely mechanicization design, structure simple, non-maintaining, and can effectively ensure that row
The advantages of vehicle and road safety.
To achieve the above object, technical scheme is as follows:
A kind of urban road safety height-limiting device, the column being fixed on road including two, the column top are set

As shown in Fig. 1, the present invention is a kind of urban road safety height-limiting device, including two columns 5, on column 5
Side is equipped with height-limiting bar 13, and 5 bottom of column embedment underground is fixed, and the height-limiting bar 13 of top setting is located at 5 top of column, limit for height
Bar 13 is used to limit the height of passing vehicle.The invention also includes roadblock cabinet 6, roadblock cabinet 6 is laterally embedded in 7 lower section of ground
Roadbed 1 in, 6 length of roadblock cabinet is slightly larger than the width between two columns 5, along road lateral arrangement, 6 distance of roadblock cabinet
13 length of height-limiting bar is arranged at 5~10 meters or so, vehicle pass-through from being moved at height-limiting bar 13 to 6 direction of roadblock cabinet.This hair
The upper surface of bright roadblock cabinet 6 is concordant with road surface 7, in order to avoid the normal pass situation of image road, in 6 upper surface of roadblock cabinet
Equipped with several through-holes 24, it is equipped with a telescopic Cleaning device fo street cleaning vehicle 8 in each through-hole 24, when Cleaning device fo street cleaning vehicle 8 in roadblock cabinet 6 by stretching
When out, Cleaning device fo street cleaning vehicle 8 is located above road surface 7 for stopping vehicle to pass through, and when Cleaning device fo street cleaning vehicle 8 is retracted in roadblock cabinet 6, vehicle can
Normal pass.
Cleaning device fo street cleaning vehicle 8 of the invention is driven by driving mechanism, wherein as shown in Fig. 2, driving mechanism includes several and road
Hinder the movable block 16 that bar 8 cooperates, movable block 16 and roadblock cabinet 6 are slidably matched, and 16 upper surface of movable block is inclined-plane 17, Cleaning device fo street cleaning vehicle
Idler wheel 19 is arranged in 8 bottoms, and idler wheel 19 is contacted with the inclined-plane 17 on movable block 16, and 16 side of movable block connects chain 9.Each vertical
It is equipped with a support plate 11 at the top of column 5, sliding rail 21 is set in support plate 11, sliding rail 21 is equipped with slidable sliding block 12, limit for height
13 both ends of bar are fixedly attached on the corresponding sliding block 12 in lower section, and height-limiting bar 13 can supported by the cooperation of sliding block 12 and sliding rail 21
It is slided on plate 11,13 rear end of height-limiting bar connects corresponding 9 one end of chain, 5 inner hollow of column, and each 5 side of column is equipped with one
A protecting tube 2 for being embedded in underground, 2 one end of protecting tube are connected to column 5, are connected inside 2 other end of protecting tube and roadblock cabinet 6
Logical, chain 9 is arranged inside protecting tube 2 and column 5, plays certain protective action, and 9 both ends of chain connect height-limiting bar 13, activity
Block 16, to form linkage mechanism between movable block 16 and height-limiting bar 13.
Working principle of the present invention is as follows:
Under normal pass state, lower than the vehicle normal pass of height-limiting bar 13, Cleaning device fo street cleaning vehicle 8 is retracted in roadblock cabinet 6
The normal pass for not influencing vehicle, when there is the vehicle higher than height-limiting bar 13 to be forced through, since height is higher than height-limiting bar 13,
Therefore roof will push the sliding of height-limiting bar 13, and height-limiting bar 13 pulls chain 9 to move, and chain 9 drives movable block 16 to move in turn, by
It is inclined-plane 17 in 16 top surface of movable block, Cleaning device fo street cleaning vehicle 8 can be pushed to stretch out of roadblock cabinet 6 by the cooperation on the inclined-plane 17 and idler wheel 19
Out, Cleaning device fo street cleaning vehicle 8 is exposed to the front of vehicle on road surface after stretching out, and recognizes that vehicle can not positive normal open after vehicle drivers discovery
It crosses, so that the present apparatus plays the role of safety height-limiting, timely and effectively driver can be played a warning role.
