Description
Technical field
The invention belongs to isolation facility technical field, and in particular to it is a kind of can be with the main barrier of the combined type net barrier of Vehicles separation
Frame lift bearing device.
Background technology
The net barrier that applicant is mentioned above does not imply that the common guardrail for road of people, and refers to special-purpose
Interim barrier facility, so-called special-purpose is such as：Assembled a crowd to make trouble as caused by unexpected incidents region, serious accident of reply is existing
The region and mass-sending that field is temporarily isolating are made trouble, and part is caused to be likely to cause dysgenic area to office, school, military restricted zone
The isolation in domain, or even use to form barrier as isolation of the military purposes for thoroughfare.
It is applied to the isolation facility of foregoing occasion in prior art（Industry custom claims roadblock or barrier）Mostly by combined type
Roadblock mesh sheet be pre-equipped with, on military or police vehicle, placing obstacles（Also referred to as cloth hinders）When carried off by manpower from vehicle, put
Isolation place is placed in, then adds support and is fixed, sets flexibly although this roadblock mesh sheet has and topography and geomorphology is adapted to
The strong strong point of property, still, operation intensity during due to placing obstacles is big, and the time that places obstacles is tediously long, efficiency is low and impact resistance is crisp
It is weak, thus the army of being not exposed to, the police think highly of.
When foreign countries carry out sealed, shield is often held by People's Armed Police and/or policeman and forms wall barrier, this mode is only capable of playing
The effect in a period of time, persistence is poor, and road or specific region can not be implemented it is really sealed, or even cause sealed injury to personnel or
It is lethal, it is also easy to be broken in addition, the impact of the vehicles of more powerless reply vehicle etc；Using container closure abroad
It is not rarely seen, but container volume is big, heavy, transportation loading and unloading is difficult, the length that places obstacles is difficult to control；Although portable kinfe rest tool
There is the advantage for facilitating short-distance movement, but with the shortcoming for depositing container envelope barrier, and impact resistance is poor；Divider wall collects except existing
Outside the shortcoming of vanning, also exist place obstacles the cycle it is long the problem of.
Certainly, agility when whether hindering from cloth and convenience when removing barrier or the labor from mitigation manual operation
Fatigue resistance factor considers, makes to remove barrier and cloth barrier all can be by means of onboard power, then can yet be regarded as is by both vehicle and net barrier together
A kind of act of ideal, but following 2 points of shortcomings at least be present in actual proof：One be due to car, barrier both involve each other and can not
Separation, therefore cost of possession is larger, i.e. a car one barrier occupies the vehicle resources of preciousness；Endangered twice second, easily producing, because
For the fuel of vehicle（Fuel tank）It is difficult to resist the combustibles artificially thrown.
The road barricade vehicle that Chinese invention patent Authorization Notice No. CN100408758C is provided, net barrier is provided on trailer, by
For main vehicle by after trailer towing to cloth barrier scene, main car can sail out of cloth barrier scene, can avoid taking main carfare source, but cloth
Hinder and remove barrier and still need to by manual operation, for details, reference can be made to the explanation of the patent specification 13-25 rows of page 5.In addition, also deposit
Squeezed in resistance external force and push away the shortcoming that ability is weak and easily goes beyond.
Certainly, it is undoubtedly pole if it vehicle can be had into the effect as escaping unnoticed relative to firm net barrier and separated
The selection of cause, because so can both save vehicle resources, and oil tank of vehicle is avoided to be attacked by combustibles and trigger accident, again
Net barrier can be made to be made to heavily fortified point to be not easy to break.The Authorization Notice No. proposed by the applicant is CN102061670B（Can be automatic with vehicle
The combined type net barrier of separation）、CN102061671B（Car, the barrier separating mechanism of combined type net barrier）And CN102146662B（Combination
The gradient compensation mechanism of formula net barrier）Patent of invention has reached foregoing purpose.
Pass through the reading to above mentioned three patent documents：The lifting and supporting of main barrier frame are by four main barrier framves
Lift bearing device（Three patents claim " main barrier frame lowering or hoisting gear "）Take on, specifically, the side before and after the left end of main barrier frame
