Description
Technical field
The present invention relates to technical field of vehicle detection, specially speed platform brake apparatus.
Background technique
Speed platform, also known as Bus- Speed Monitoring platform are the special equipments for detecting vehicle speed.Two free rollers are generally comprised,
When detecting vehicle speed, vehicle wheel rotation drives two free roller rotations of speed platform, and the speed by detecting free roller is
Vehicle speed can be measured.After the completion of detection, free roller stops operating, and vehicle is opened from speed platform.Vehicle open from when, need to brake
Free roller prevents free roller from rotating together with wheel, to enable the vehicle to smoothly open from speed platform.
In the prior art, brake apparatus is generallyd use to brake free roller.This kind of brake apparatus is resistance to using two
Mill tile offsets with free roller respectively, so that free roller be held tightly, passes through the friction between wear-resisting tile and free roller
To realize the braking of free roller.
Although this kind of brake apparatus can reach basic brake request, vehicle open from when, the power of wheel is larger,
Its active force for passing to free roller is larger, only brakes free roller by the friction between free roller and wear plate, makes
Dynamic effect is bad, and vehicle easily skids.In order to reach preferable braking effect, then the preferable tile of wear-resisting property must be used,
Its cost is too high.In addition, the friction of wear-resisting tile and free roller is larger, the service life of wear-resisting tile is caused to greatly reduce,
It needs to be replaced frequently, virtually increases equipment cost.
Summary of the invention
The invention is intended to provide a kind of speed platform brake apparatus, to solve the problems, such as that braking effect is bad in the prior art.
In order to achieve the above object, the invention provides the following technical scheme:
Speed platform brake apparatus, including support frame, support frame bottom are connected with driving mechanism, are arranged on support frame with teeth
Plate, tooth plate top are provided with roller, setting rack gear concentric with it in roller, and gear ring and are fixedly installed, be provided in the middle part of gear ring
First through hole, the roller are surrounded by the slide plates of several mutual sliding settings, and roller one end is provided with baffle, if baffle and described
Spring is respectively connected between dry slide plate；Support frame side is connected with tapered bar vertically, is provided with push rod, push rod one end shape above tapered bar
At with the matched wedge surface of the tapered bar, be provided with the push plate that can push slide plate below push rod, push rod two sides are respectively connected with L shape
Connecting rod, the connecting rod other end connect with the push plate both ends respectively.
The principle of this programme are as follows:
Support frame is used to support tooth plate, and to ensure that tooth plate stablizes installation, driving mechanism is used to that support frame to be driven to move up,
It is moved up with band moving tooth plate, so that tooth plate is engaged with gear ring, is engaged by tooth plate with gear ring, it, can since gear ring is fixedly installed
To be fixedly installed in rack, so that resting barrel, realizes the braking of roller.Slide plate surrounds roller, when testing the speed, roller and vehicle
Wheel offsets, to complete to test the speed by the speed of the velocity determination wheel of test roller.After the completion of testing the speed, driving mechanism driving branch
Support moves up, and support frame drives tapered bar to move upwards, and tapered bar can act on the wedge surface of push rod and push rod is pushed to tooth
Circle is internal, and the push plate below push rod, which can be pushed, generates sliding between the slide plate that push plate offsets and other slide plates, will with push away
The slide plate that plate offsets is to baffle Slideslip, to expose gear ring, so that gear ring is engaged with tooth plate, to realize the braking of roller.
The invention has the benefit that
1, it is engaged by gear ring with tooth plate, utilizes frictional force brakes roller, braking effect of the invention compared to the prior art
Fruit is more preferable, will not skid.
2, the present invention engages the braking for realizing roller by tooth plate with gear ring, and the abrasion that tooth plate and gear ring are subject to is less, makes
It is long with the service life, the frequency of more exchange device is reduced, to reduce equipment cost.
3, support frame is pushed by driving mechanism, so that tooth plate is engaged with gear ring, while can also drive tapered bar to move, to push away
Dynamic push rod, it is energy saving without in addition using power mechanism driving push rod.
Further, tooth plate cross section is in be detachably connected with the matched arc of gear ring, tooth plate with support frame.It can so mention
The degree of engagement of high tooth plate and gear ring, to improve braking effect.Tooth plate and support frame are detachably connected tooth plate removing maintenance
And maintenance.
Further, expansion plate, expansion plate outer wall and the roller are also connected between several slide plates and the baffle
Outer surface flush.Expansion plate can give cooperation telescopic spring, and complete cylinder wall can be formed with sliding block when extending, with
Support wheel.
Further, the slide plate cross section is arc, and slide plate outer surface is coated with anti-slip layer, and push plate is also in and slide plate phase
Matched arc.Slide plate section is that arc can guarantee that each slide plate closely connects, and anti-slip layer can prevent wheel-slip.
Further, the roller other end is provided with cover board, and cover board is fixedly connected with the end of gear ring, is arranged on cover board
There is the second through-hole, the diameter of the second through-hole is identical as first through hole, and the axis of the second through-hole is overlapped with the axis of first through hole,
Arcuate socket identical with the push plate shape is additionally provided on cover board.Cover board, which can prevent dust from entering drums inside, leads to device
Damage, extends the service life of device.
Further, cover board is detachably connected with roller.Cover board is detachably connected to remove cover board, to drums inside
Component repairs.
Further, driving mechanism is cylinder.Support frame is pushed using cylinder, it is more efficient.
