Abstract
The invention includes two sets of motor installed on two sides of trailer, pairs of wheel, pairs of chain wheel, and pairs of pinch chain wheel. Characters of structure are that coaxial connection chain wheels are located on two outsides wheels; rounded chain connects each chain wheel on same side. Pinch chain wheels are setup between two adjacent chain wheels, and at two end parts. Chain passes through under each pinch chain wheel. Being fixed on two sides of wheel respectively, each driving motor is connected to wheel. Comparing with prior art, the invention saves floor space, simplifies system configuration, and raises operational reliability.
Description
Technical field
The present invention relates to the acting trailer system technical field that radiant image detects, especially for the driving mechanism of trailer in the radiation image-forming system.
Background technology
Radiation imaging check system is the essential checkout equipment of customs, Civil Aviation Airport and the railway system.It is in a building can shield the sense channel of ray, fixed radiation source is housed and can accepts to pass the detector array of tested vehicle ray, and the vehicle that special-purpose actuator will be equipped with container is checked by beam.The ray that sees through container passes to detector, and detector reflects the Density Distribution of the object of adorning in the outlet according to the variation of transmitted intensity, and transmitted intensity is transformed into gradation of image, can obtain the fluoroscopy images of the object of adorning in the case.In the prior art, the actuator of this special use mainly adopts flat-bed trailer or plate-and-chain conveyer, what 2000 types series collection loading thing/vehicle inspection system of producing as U.S. Rapiscan company adopted is that flat-bed trailer drags, it reaches whole container truck on the flat-bed trailer, and flat-bed trailer carries container truck and passes through beam.The flat-bed trailer floor area is big, cost is high, because it can't make image quality not high to the instability of reliable location of tested vehicle and self-operating, also higherly causes tested vehicle to upload inconvenience owing to flat-bed trailer is liftoff.And the polygon effect that adopts the plate chain to carry can make image quality descend, and noise is very big.In order to overcome the shortcoming that exists in the above-mentioned prior art, it number is " a kind of trailer that is used for autoscan formula large-sized object radiation checking system " patent of invention of 02148669.7 that the applicant has declared a Chinese patent application on November 15th, 2002, and to have declared Chinese patent application on October 16th, 2003 again on the basis of above-mentioned patented claim number be that 200310100183.6 " a kind of acting trailer system that is used for radiant image " and Chinese patent application number are " a kind of trailer that is used for the acting trailer system of radiant image " two patents of invention of 200310100184.0, it is low that they have a noise, floor area is little, the characteristics that cost is low, and improved traveling comfort, reduced the car body platform, be convenient to tested vehicle and upload, also increased device simultaneously tested wheel of vehicle location and the grappling of trailer own.But all need winch be set in the above-mentioned acting trailer system, and the wire rope of winch be fastened to be connected with the lanyard on the trailer carry out traction drive at the two ends of checking passage.The shortcoming of this traction drive form is, can produce bigger impact to wire rope in trailer start-stop process, and this drive system floor area is big, and link is many, poor reliability.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of many wheels chain synchronous drive mechanism that is used for the radiation image-forming system trailer.It is contained in drive unit each wheel is rotated synchronously, has saved floor area, has simplified system configuration, and functional reliability improves greatly.
In order to realize above-mentioned goal of the invention, technical scheme of the present invention realizes as follows:
A kind of trailer multiple wheel chain synchronous driving mechanism that is used for radiation image-forming system, it comprises the two cover motors, many to wheel, a plurality of sprocket wheel and a plurality of pressing sprocket that are installed in the trailer both sides.Its design feature is that the described coaxial connection sprocket wheel of each lateral wheel that is positioned at the trailer both sides connects each sprocket wheel of homonymy with the chain that goes in ring.Between adjacent two sprocket wheels, reach sprocket wheel place, both ends pressing sprocket is set, chain is passed through from the bottom of each pressing sprocket.Described each motor is separately fixed at the both sides road wheel end and is in transmission connection with a wheel.
In above-mentioned many wheels chain synchronous drive mechanism, described wheel and sprocket wheel are four pairs.
In above-mentioned many wheels chain synchronous drive mechanism, the described pressing sprocket number that is arranged in adjacent two sprocket wheels and the both ends sprocket wheel is made as one or more according to the length of institute's pressure chain.
The present invention is owing to adopted above-mentioned structure, and it directly is contained in drive unit on the trailer, and drives each wheel and rotate synchronously, has made full use of the clinging power between wheel and the rail, for trailer provides enough big driving force.Compare with prior art, the present invention has saved floor area, has simplified system configuration, functional reliability improves greatly.
The present invention is described further below in conjunction with accompanying drawing and concrete embodiment.
Description of drawings
Fig. 1 is applied to the structural representation of trailer for the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of sprocket wheel annexation of the present invention.
Embodiment
Referring to Fig. 1 to Fig. 3, the present invention includes and be installed in the perpendicular wheel of listing in trailer 10 both sides of two on the trailer 10 cover motor 8, four pairs 1, four sprocket wheels 2 and four pressing sprockets 3.Be positioned at each coaxial connection sprocket wheel 2 in wheel 1 outside of trailer 10 both sides, each sprocket wheel 2 of homonymy connected with the chain 4 that goes in ring.Reach both ends sprocket wheel 2 places between adjacent two sprocket wheels 2 pressing sprocket 3 is set, chain 4 is passed through from the bottom of each pressing sprocket 3, the number of pressing sprocket 3 is made as one or more according to the length of institute's pressure chain 4.Each motor 8 is separately fixed at both sides wheel 1 end and is in transmission connection with a wheel 1.
Before the present invention uses, adjust the position of each pressing sprocket 3, make the upper and lower layer chain 4 and the sprocket wheel 2 in each wheel 1 outside that enough cornerites and mutually noninterfere be arranged.During use, trailer 10 is placed in the inspection passage of scanning area, make the fixing anchoring device locking in trailer 10 and ground.When tested vehicle was driven trailer 10 by the last ramp of trailer 10 1 ends, the lock wheel mechanism 9 on the usefulness trailer 10 was with front wheel locking.Start each motor 8 then, each motor 8 is by chain 4 each wheel 1 rotation of each sprocket wheel 2 drive of transmission respectively.Each wheel 1 on the trailer 10 is started and operation synchronously.Like this, the tested vehicle of trailer 10 drives passes through scanning area reposefully.After inspection finishes, with trailer 10 grapplings, discharge lock wheel mechanism 9, tested vehicle launch can sail out of from the following ramp of trailer 10.
