Description
Technical field
The invention belongs to road isolation facility technical field, and in particular to a kind of combined type having for personnel's current function
The major network barrier length compensation mechanism of net barrier.
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：Assemble a crowd to make trouble as caused by unexpected incidents region, serious accident of reply is existing
The region that is temporarily isolating of field and mass-sending make trouble organ, school, military restricted zone etc. are likely to cause caused by part it is dysgenic
The isolation in region, or even use for the isolation on thoroughfare as military purposes and to form barrier.
It is applied to the isolation facility of foregoing occasion in prior art（Industry custom claims roadblock）Mostly by knockdown roadblock
Mesh sheet is pre-equipped with, on military or police vehicle, placing obstacles（Also referred to as cloth hinders）When carried off by manpower from vehicle, be positioned over every
It is liftoff, then add support and fixed, although this roadblock mesh sheet is flexibly and adaptable to topography and geomorphology with setting
Strong point, still, operation intensity during due to placing obstacles are big, and the time that places obstacles is tediously long, inefficiency and impact resistance are fragile, thus
The army of being not exposed to, the police think highly of.
When foreign countries carry out sealed, shield is often held by soldier 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 since container body product is big, heavy, handling transport difficult, the length that places obstacles is difficult to control；Though the portable kinfe rest
So there is the advantage of 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 at least there are following 2 points shortcomings for 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
The shortcoming that the ability of pushing away is weak and easily goes beyond is squeezed in resistance external force.
Certainly, it is undoubtedly pole if it vehicle can be had the effect as escaping unnoticed relative to firm net barrier and separated
The selection of cause, because so can both save vehicle resources, and avoids oil tank of vehicle from being 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.Then, " the combined type recommended by Chinese invention patent Authorization Notice No. CN102146662B
Net barrier gradient compensation mechanism ", CN102061670B provide " combined type net barrier that can be automatically separated with vehicle " and
" combined type net barrier car, the barrier separating mechanism " that CN102061671B is introduced has reached object defined above and this three patents are taken off
Major network barrier length compensation mechanism is shown.From the noun paraphrase of major network barrier length compensation mechanism and with reference to this three patent descriptions
Book is understood：When running into the relatively spacious major network barrier without being enough to be limited to by its length of road and reaching sealed purpose, then
The major network barrier length compensation mechanism configured in a manner of deposit on major network barrier is enabled, by major network barrier length compensation mechanism collaboration major network
Hinder sealed, vice versa.
By taking foregoing CN102061670B and CN102061671B as an example, by the 0044th to 0046 section of its specification
Description is understood：Major network barrier length compensation mechanism mainly includes a secondary net barrier driving device and a secondary net barrier, pair net barrier driving device
Including motor, gear reducer, first, second drive and transmission belt, motor matches somebody with somebody to merge with gear reducer to be led to by gear reducer together with motor
Cross the bottom that reducer pedestal is fixed on major network barrier（Positioned at right end）, the first drive is fixed on the output shaft of gear reducer, and second
Drive is arranged on the bottom of major network barrier by mounting base（Positioned at left end）, transmission belt consolidates with the transmission belt being preset on secondary net barrier
Determine ear to fix and be nested with first, second drive, pair net barrier forms nesting relationship and in secondary net barrier with major network barrier
Bottom is provided with roller, roller and the guide rail composition rolling pair for being fixed on major network barrier bottom.
Although above-mentioned CN102146662B, CN102061670B and CN102061671B can objectively fulfil respective explanation
Technique effect described in the technical effect column of book, but there are following four in terms of logical disadvantage：First, when net barrier（That is roadblock,
It is the same below）Complete after setting up, in the whole sealed length range that places obstacles, barrier, the specific people of the outer both sides of barrier for example hinder in police
Popular representative outside member, barrier etc. is impassable, can only be bypassed from the end of roadblock, particularly when a plurality of nets hinder to circulate group
When the form of conjunction is connected, it is even longer that the length of whole roadblock can reach rice up to a hundred, and then in barrier, barrier is outer dispatches officers to link up more
For inconvenience；If second, reserve personnel's transit passage using the retraction of secondary net barrier, it is necessary to start dynamical system in roadblock and
Driving device bounces back hinder heavy secondary net, and time length is cumbersome, and energy source consumption, is needing the short time frequent
It is extremely inconvenient during personnel channel to open and close；Third, the chain due to the secondary structural system for netting barrier driving device（Patent claims " transmission
Band "）It is and the chain fixed ear on secondary net barrier（Patent claims " transmission belt fixed ear " to fix）, thus chain is consolidated with what secondary net hindered
Determine effect to be difficult to persistently ensure, during the secondary net barrier movement of chain traction, chain and the stress concentration of fixed ear junction,
There are the fixed ear anxiety de- with secondary net barrier point；Fourth, since the secondary structural system for netting barrier driving device employs motor with slowing down
The long side direction that the fit form and set-up mode of machine show as being parallel to major network barrier is set, and due to motor and gear reducer
Both length makes first, second sprocket wheel at one meter or so（Patent claims " first, second drive "）The distance between by
To limitation, i.e., since the length of motor acceleration and deceleration machine has occupied the distance between first, second sprocket wheel to a certain extent, so that
