Description
Technical field
This utility model belongs to bridge inspection technical field, is specifically related to a kind of suspension bridge and checks the walking mechanism of car.
Background technology
Up to now, China Express Railway operation mileage, close to 20000km, is that high-speed railway operation mileage is the longest in the world
Country.This also indicates that China has been the longest country of high-speed rail bridge mileage.As time goes on, high-speed rail bridge structure
Disease will be put in face of people, the track traffic accident brought due to bridge hidden danger, the often pernicious thing of car crash
Therefore.Thus bridge is carried out periodic inspection and has naturally become a critically important problem.
It is big that China Express Railway has bridge ratio, the feature that overhead long bridge is many, and novel High-speed Railway Bridges beam bridge floor becomes
Narrow, both sides are own without traveling sidewalk.Circuit also has operation density is big, closure strong, the spy of Measuring error the limited time simultaneously
Point.On the one hand this cause the maintenance issues of high-speed rail bridge to become more acute, on the one hand causes again existing Bridge Testing Equipment
And means cannot adapt to the detection job requirements of current high-speed railway bridge.It would therefore be highly desirable to exploitation is according to China Express Railway bridge
The detection equipment that beam technology is derivative.
High-speed railway concrete standard box girder bridge check car (hereinafter referred to as " bridge-checking vehicle ") be one can be bridge machinery personnel
Job platform, equipment are provided, for flowing checking and the professional vehicle of maintenance, are drawn by self power or railcar, energy
Quickly arrive operating location, effectively utilize skylight point；Operation process does not affect and faces line traffic, and operation can not be regained, if
Standby low speed traveling between operating point, work efficiency is high.Bridge-checking vehicle is usually installed special on the basis of big locomotive frame chassis
Equipment form.According to the difference of Working mechanism, substantially there are basket-hanging and truss-like two kinds.
At present, traditional rail-mounted bridge-checking vehicle, either basket-hanging or truss-like, its Working mechanism is all from circuit both sides water
Flattened go out, be limited by the vertical rod of circuit both sides, after completing an operating point, Working mechanism must be retracted to SBR and keep away
Open bar could run to next operating point.Between two operating points, operating personnel must repeatedly handle implement receive,
Putting, not only inefficiency, staff is also easy to tired out, and this is obvious is to run counter to the high speed of high-speed railway, efficiently requirement
's.
Abroad overhaul for the operation in the future of bridge, pass through for not affecting normal traffic, in design and the beginning of construction, the most pre-
Stay bridge-checking vehicle passage or pre-buried detecting element and adnexa, and domestic high-speed rail bridge majority has not the most done corresponding consideration
Design, simultaneously in order to reduce bridging cost, some bridge deck-sidings narrow, and without sense channel, this is the machine with axle casing
Tool Quick overhaul brings inconvenience.So develop one not use sense channel, be not take up rail track and can the company of realization
The bridge-checking vehicle of continuous formula Inspection, is necessary, is also key issue urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to solve the problems referred to above, it is provided that one utilizes bridge air vent as main bearing point, replaces
Formula voluntarily lay a railway track walking walking mechanism, reach suspension bridge check car do not use sense channel, be not take up rail track and
The purpose of continuous way Inspection can be realized.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of suspension bridge checks the walking mechanism of car,
Including the track arranged along bridge length direction, track is provided with the first latch element, the second latch list along its length direction
Unit and the 3rd latch element, the first latch element is positioned at track one end and is fixedly linked with track, the second latch element and the 3rd
Latch element is all removable with track to be coordinated；First latch element, the second latch element and the 3rd latch element are equipped with can edge

204 by the second driving gear 205 and coordinating of the second tooth bar 206 realizing the bridge air vent 6 into and out bridge side.
Being additionally provided with walking unit on second pedestal 201, walking unit is removable with track 4 to be coordinated.Walking unit includes fixing
Travel driving motor 207 on the second pedestal 201, be located at travel driving motor 207 outfan driving gear 208 and
The driven gear 209 of driving gear 208 engagement and the road wheel 210 that rotates coaxially with driven gear 209, driving gear
208 and driven gear 209 form gear driving pair, thus the rotation of travel driving motor 207 is transferred to road wheel 210,
Road wheel 210 rolls with track 4 and coordinates, it is achieved the walking on track 4 of second latch element 2.
Steady during in order to keep suspension bridge to check car operation, it is to avoid rock, slip car and tumbling, driving gear 208, from
The quantity of moving gear 209 and road wheel 210 is two, and two of which driving gear 208 is co-axially mounted, road wheel 210
Laying respectively at the both sides of track 4, travel driving motor 207 drives two driving gears 208 to rotate, respectively with two simultaneously
Driven gear 209 concomitant rotation of driving gear 208 engagement, each driven gear 209 drives the walking being coaxial therewith connecting
Wheel 210 rotation.
Particularly, the second pedestal 201 lower end of the second latch element 2 is fixedly linked with car body truss 5.
Road wheel in the present embodiment all uses polyurethane Baogang road wheel.
As illustrated in figs. 5-7, operation principle and the process of above-mentioned walking mechanism is:
(1) starting to advance, now the first latch of the first latch element, the second latch of the second latch element and the 3rd insert
3rd latch of pin unit all inserts bridge air vent and walking mechanism and car body truss is fixed, and walking mechanism is in walking shape
State one；
(2) the 3rd latch element extract the 3rd latch, under the effect of the walking unit of the 3rd latch element, and the 3rd latch list
Unit is along the distance of two bridge air vents of slide, fixing during then the 3rd latch inserts bridge air vent, is now in row
Walk state two；
(3) second latch element extract the second latch, under the effect of the walking unit of the second latch element, and the second latch list
Unit and car body truss are along the distance of two bridge air vents of slide, and then the second latch is solid in inserting corresponding bridge air vent
Fixed, it is now in walking states three；
(4) first latch element extract the first latch, are connected owing to the first pedestal and the track of the first latch element are fixing,
Under the common effect of the walking unit of the second latch element and the 3rd latch element, the first latch element together with track along bridge
The distance of two bridge air vents of beam length direction slip, during after arriving precalculated position, the first latch inserts corresponding bridge air vent
Fixing, it is now in walking states four.
Now walking states four has advanced than walking states one entirety the distance of two bridge air vents, is arrived by walking states one
The circulation successively of walking states four can realize suspension bridge and check the alternative expression walking of car, and every circulation primary can realize 2m or 4
The walking of m.
Those of ordinary skill in the art is it will be appreciated that embodiment described here is to aid in this practicality of reader understanding newly
The principle of type, it should be understood that protection domain of the present utility model is not limited to such special statement and embodiment.Ability
The those of ordinary skill in territory can be made various real without departing from this utility model according to these technology enlightenment disclosed in this utility model
Other various concrete deformation and combination of matter, these deformation and combination are still in protection domain of the present utility model.
