Description

Temporary protective fence for municipal administration

Technical Field

The invention relates to the technical field of municipal guardrails, in particular to a temporary guard rail for municipal administration.

Background

The municipal road guardrail is also called as a galvanized plastic-sprayed steel guardrail for urban traffic, is attractive and novel, is easy to install, safe and reliable, and has a preferential price. The method is suitable for isolating urban traffic main roads, intermediate green isolation belts of highways, bridges, secondary roads, village roads, toll gates of various roads and the like.

The Chinese patent with the publication number of CN112942193A discloses a municipal street crash barrier, which comprises a plurality of groups of barrier components spliced and connected along the horizontal direction, wherein each barrier component comprises two upright posts installed on the ground and an elastic belt connected between the two upright posts, two ends of each elastic belt are respectively fixedly connected with a rotating post, and the elastic belt is partially wound on the rotating posts; the upper end and the lower end of the rotating column are respectively provided with a rotating shaft along the vertical direction in a sliding manner, the opposite end surfaces of the two upright posts are respectively provided with a rotating groove for the rotating column to extend in, the upper side wall and the lower side wall of the rotating groove are respectively provided with a yielding groove for the end part of the rotating shaft to extend in, and the rotating column is detachably connected with a driving piece for respectively driving the rotating shaft to be kept in a state of extending out of the rotating column. The impact force absorbing device has the effect of being capable of absorbing impact force generated when a vehicle collides with the guardrail.

However, in the above technical solution, there are certain disadvantages: 1. when the structure is used, the width cannot be adjusted according to the requirement, and the top of the guardrail cannot prevent people from crossing over, so that the blocking effect of the guardrail is greatly reduced;

2. when the structure is used, the plurality of guardrails are connected through the splice plates, and the two guardrails are connected through the splice bolts during connection, so that the time required during connection is long, and the installation and the disassembly are both inconvenient.

Disclosure of Invention

The invention aims to provide a temporary guard rail for municipal administration, which solves the problems that the width proposed in the background art cannot be adjusted, personnel cannot be prevented from crossing over, and the butt joint and disassembly of a plurality of guardrails are complicated.

In order to achieve the above purpose, the present invention provides the following technical solutions: a temporary guard rail for municipal administration comprises a vertical frame,

the vertical frames are provided with a plurality of groups, two inclined partition rods are rotatably arranged between the adjacent vertical frames, the front inclined partition rods and the rear inclined partition rods are rotatably connected through a rotating shaft, the end parts of the adjacent inclined partition rods are penetrated by a second rotating shaft in the same front-back direction, the front end and the rear end of the second rotating shaft are respectively rotatably connected with a lifting installation block, the two lifting installation blocks are respectively and slidably installed in lifting sliding grooves formed in the front side and the rear side of the inner wall of the vertical frame, and the top parts of the lifting installation blocks are connected with a reverse transmission assembly;

the top of standing the frame runs through and installs liftable prevent turning over the spine, and prevent turning over the bottom of spine and be connected with reverse drive assembly, stand the frame and include butt joint frame and unblock frame, and butt joint frame and unblock frame are located a plurality of rightmost and leftmost of standing the frame respectively, one side that the frame was kept away from to the butt joint frame is provided with the butt joint piece, be provided with the push pedal on the unblock frame.

Through adopting above-mentioned technical scheme, the pulling butt joint frame for the interval changes between butt joint frame and the upright frame, and then the inclination that the slope cut off the pole increases, and then makes each group slope cut off the pole inclination increase, and concrete principle is similar with the flexible door, when slope cut off the pole inclination grow, the top that the slope cut off the pole can drive the lift installation piece through pivot two and slide downwards in the lift spout, utilizes reverse drive assembly to drive to prevent turning over the spike and stretches out in the upright frame this moment, when reaching the guardrail transversely opens, the tip is prevented turning over the spike and stretches out voluntarily at top, plays the effect of preventing personnel's the crossing.

As a further scheme of the invention: the bottoms of the adjacent vertical frames are connected with multi-stage telescopic rods, the lengths of the multi-stage telescopic rods can be changed along with the change of the distance between the vertical frames, and universal self-locking wheels are arranged at the bottoms of the vertical frames.
