Description

The bottom tool car of railway, road bridge

The utility model relates to a kind of work car that railway bridge or road bridge bottom are checked, keeped in repair.

The girder steel of railway and road bridge disposes the bottom inspection trolley in its bottom usually, so that girder steel rail level or the steel structure below the road surface and concrete structure are checked or keeped in repair.Inspection trolley reversal of the natural order of things in the past is on the rail below the girder steel lower boom, and the walking wheel of wanting two people to shake two simultaneously could vertically be walked along walking the newline rail.Because truss is about 7-8 rice, the walking wheel at two does not have synchronous device, even two people shake walking wheel simultaneously at two, can occur unavoidably that vehicle body reverses, clamping stagnation is difficult to the situation of walking on rail yet.In addition, inspection trolley hangs upside down under rail, is river, river, ditch, paddy below it, does not have any measures on the car again, in case the unexpected fracture of a certain sling point, vehicle body just can fall, and causes personal injury and equipment damage grave accident.Moreover inspection trolley is articulated in the top of lower boom, apart from girder steel bottom lateral bracing and longeron certain altitude arranged still, and the staff will climb on the bottom lateral bracing and could work, and often needs upper and lowerly, both influenced work efficiency, increase working strength of workers again, and danger is bigger.

The purpose of this utility model is exactly for overcoming the deficiency described in the above-mentioned background technology, and design a kind of can be along the synchronous traveling of lower boom, bench board can lifting, and has the bridge bottom tool car of insurance and braking dual-use function.

To achieve these goals, the utility model proposes the corresponding techniques solution:

The bottom tool car of this railway, road bridge comprises car body, and it mainly is respectively to be provided with suspension bracket at the both ends of car body, and each suspension bracket all has the walking wheel that cooperates with the fixing track of girder steel lower boom, and synchronizing shaft is through between two suspension brackets; Be provided with a liftable tower wagon on car body, the safety clutch that is made of matrix card, handwheel, leading screw, brake disc and spring articulates in orbit.Walking wheel and upper sprocket wheel are an axis, also are connected with crank on axis, upper sprocket wheel and be connected with driving chain between the lower sprocket of synchronizing shaft termination.Tower wagon top has a bench board that has a guardrail, and the tower wagon bottom is provided with the travelling wheel that can move on car body.A pair of spill card in the safety clutch hangs in orbit, and the leading screw that two ends have handwheel and brake disc respectively penetrates in the cavity that is made of two spill cards, and the connecting rod sleeve that links to each other with the spill card has spring.

The A-A face cutaway view of Fig. 2: Fig. 1.

The B-B face structure for amplifying scheme drawing of Fig. 3: Fig. 2.

As shown in Figure 1 and Figure 2, the utility model mainly is made up of car body 7, suspension bracket 12, tower wagon 5, synchronizing shaft 13, traveling gear and safety clutch 20.Wherein, car body 7 is a rectangle steel truss structure, and two suspension brackets 12 are fixed on two of car body 7, and synchronizing shaft 13 is connected between two suspension brackets 12, respectively is provided with lower sprocket 3 at the two ends of synchronizing shaft 13.Suspension bracket 12 tops have be fixed on girder steel lower boom 1 on the walking wheel 8 that matches of track 2, upper sprocket wheel 9 is installed with walking wheel 8 axises, crank 11 joins with axis.Between upper sprocket wheel 9 and lower sprocket 3, be connected by driving chain 11.When rotating crank 10, upper sprocket wheel 9 drives lower sprocket 3 and drives synchronizing shaft 13 by chain 11 and rotates synchronously.Synchronizing shaft 13 is by the bearing and the bearings that are fixed on the car body 7.Hydraulic pressure tower wagon 5 with elevating function is made up of cross link, and by hydraulic-driven, its upper design has the bench board 4 of a band guardrail so that the staff works within it, and have safe and reliable, avoid accident characteristic.Tower wagon 5 bottoms are equipped with travelling wheel 6, and whole tower wagon 5 can be by travelling wheel 6 along moving back and forth on the bottom girder of tool car trussed steel beam.

Fig. 3 shows the structure for amplifying of safety clutch 20.This safety clutch 20 has 14 pairs on 14, two matrix cards of two relative matrix cards and is stuck on the track 2, the connecting rod 19 outer springs 17 that are with that link to each other with matrix card 14.An end that has brake disc 15 on the leading screw 16 extend in the two matrix cards 14, and brake disc 15 is corresponding with track 2 bottom surfaces.The other end of screw mandrel 16 is provided with a handwheel 18.

Track 2 welding or be riveted on the lower boom 1 of railway bridge or road bridge, walking wheel 8 is articulated on the track 2, so by suspension bracket 12 whole locomotive body 7 is hung bottom at bridge.Rotate crank 10 by the people, upper sprocket wheel 9 is driven with lower sprocket 3 friction tight synchronizing shafts 13 by driving chain 11 rotate.Because the effect of synchronizing shaft 13, as long as rotate crank 10 on one side, the upper and lower sprocket wheel 9,3 and the chain 11 of another side promptly drive walking wheel 8 synchronized operation on track 2, move under bridge so can drive whole locomotive body 7.Owing on car body 7, be provided with the hydraulic pressure tower wagon 5 of a band guardrail bench board 4, so the workman can arbitrarily control, adjust its height on tower wagon 5 and bench board 4, to adapt to the need of work of different occasions.Guardrail on the bench board 4 also can be eliminated the feared state of mind of workman when aloft work, has safety effect again.This tower wagon 5 is to walk on the bottom girder of car body 7 by the travelling wheel 6 of its bottom.On track 2, also be hung with two relative matrix cards 14, the connecting rod 19 outer springs 17 that are with that link to each other with matrix card 14.At ordinary times, with matrix card 14 jack-up and de-orbit 2, make that walking wheel 8 can walking successfully on track 2 by spring 17 power.When fracture appearred in certain hanging point, the top of matrix card 14 will be blocked automatically and hung on the track 2, avoids the generation of the person, equipment breakdown.If whole locomotive body 7 is fixed on a certain position, then can make brake disc 15 and track 2 bottom surface wipe contacts by leading screw 16 by rotating handwheel 18, can play brake action.

The utility model is owing to adopted synchronized operation and the structure design of movable tower wagon and insurance braking, overcome the deficiency that exists in the background technology, synchronization structure makes car body be in operation catching phenomenon can not occur reversing, the workman can use tower wagon to determine the operating altitude that is fit to easily, alleviate working strength of workers greatly, also eliminated staff's the feared state of mind.Also because of the setting of matrix card and drg, the person, equipment breakdown have greatly been avoided, improved safety, and can arbitrarily brake and make car body stop at any one work station, routine inspection, the maintenance of railway bridge and road bridge bottom seemed more convenient and practical.
