Description

Vehicle for removing obstacles on road

The utility model is a kind ofly to have lifting and rescue road that function has both (or rescue) car of removing obstacles, can be widely used in loading and unloading, rescue, rescue work, and can hang and lead vehicle ', to clear, immobilized vehicle, the vehicle technical application of parking violating the regulations ensure.

One ton of tow lift of for example Japanese Toyota of existing similar tow lift, the triangular structure of its drawbar frame for being welded with steel pipe shaped steel or steel plate, as shown in Figure 6.Therefore can not in horizontal surface, swing,, drawbar frame be damaged so when vehicle ' was on up-and-down road surface, the left and right sides, drawbar frame was turned round.And owing to be at 3 and be rigidly connected, Ackermann steer angle must influence draw groups row turn radius, it is dumb to turn, when drawbar frame shorter, turn radius hour, the wrecker afterbody easily taking place and is pulled the car front portion collides, if when drawbar frame is oversize, make the wrecker suspension bracket stressed, reduce the stability of car load, turn radius when the draw groups row are travelled increases, and makes the road crossing ability variation of vehicle.Secondly some similar vehicles structure is less in the world, and its applicability, commonality are poor, can only hang and lead little sleeping carriage, and lilliput car etc. are simultaneously because the limitation of its structure is being installed, is bundling the operating aspect inconvenience.

Task of the present utility model be exactly to provide a kind of applied widely, hoisting weight is big, turn radius is little, capacity of road is strong, and makes the non-damageable road obstacle clearing vehicles of parts such as drawbar frame.

Task of the present utility model is achieved in that and adopts existing General Motors chassis, hoisting device is contained on the car chassis of the transformation of the way, the tee girder of getting on the bus and adopting I-beam section to be welded into, so that pulling electrified monorail system moves thereon, and caging bolt is housed on the lifting position is unlikely and skids off track to guarantee to pull electrified monorail system, weight-lifting equipment adopts chain block to load and unload, lifting fault vehicle, pull the supporting use of electrified monorail system and bottle gouard moved by hands and form the lifting travelling bogie, lead frame by setting up to hang, annexes such as lift heavy iron chains and supporting base realize removing fast roadblock, rescuing the people speedily carries out rescue work, to guarantee that highway communication is unimpeded, and can do general lifting, lifting, loading and unloading operation and general goods transport operation, except that above-mentioned mechanical type hoisting and hanging form, hoist, luffing mechanism also can be by electronic, hydraulic-driven.

Below in conjunction with accompanying drawing the utility model embodiment is described further.

Fig. 1 is the integral structure front elevation of the utility model embodiment, it is by car chassis (1), tee girder (2), pull electrified monorail system (3), chain block (4), hang and lead frame (5), lift heavy iron chains (6) etc. are formed, pull the supporting composition lifting of electrified monorail system and chain block travelling bogie, can be used as general hoisting and hanging, usefulness such as loading and unloading, and lead frame (5) by means of forming hanging of four-bar linkage by cross axle sleeve and cross rotating shaft mechanism, lift heavy iron chains annexes such as (6) is realized fast, safety, lifting, remove roadblock, rescuing the people speedily carries out rescue work, to guarantee that highway communication is unimpeded, and can make general goods transport, utilize supporting base (5M) to do to dissimilar vehicles, in, the adjustment of following three height is to enlarge its field of application.

Fig. 2 leads the birds-eye view of frame (5) for the utility model hangs.

Fig. 4 leads the front elevation of frame (5) for the utility model hangs.

Wherein: (51) are the cross axle sleeve, and (52) are swing arm, and (531) are rotating pin, and (532), (533) are bearing pin, (54) lead pivoted frame for hanging, (55) are rubber plate, and (56) are steel rope, (57) be suspension bracket, (58) are grab, and (59) are camber beam.

Hang and lead frame by cross axle sleeve (51), bearing pin (511) and spring pin (512) link to each other with supporting base (510), hang and lead frame and can do in vertical direction up and down to rotate around this bearing pin (511), swing arm (513) is by rotating pin (532), (533) with cross axle sleeve (51), camber beam (59) links to each other, and lead pivoted frame (54) and link to each other with hanging by rotating pin (531), (52) can in horizontal surface, swing around (532) or (533), hang and lead pivoted frame and can rotate around horizontal shaft, so just guaranteed to hang and led frame and do not turned round, reduced and hung the wearing and tearing of leading frame, prolonged service life, and make turn radius little, capacity of road greatly improves.

Fig. 3 is a lift heavy iron chains partial enlarged drawing, is made up of welding chainlet (61) and drag hook (62).

Fig. 5 leads grab (58) front elevation that pivoted frame (54) is gone up the place, two ends for hanging, and has two mutually perpendicular deep-slotted chip breakers on (58), also can only open a straight trough, and when welding chainlet (61) was placed on the groove, iron chains one was subjected to the tractive force can be stuck.

Working process was as follows when wrecker used:

Lead when travelling hanging, hanging the end that leads frame (5) is connected with supporting base (510) on being fixed on wrecker with bearing pin (511) and spring pin (512), the other end is fixed on the vehicle bridge that is pulled vehicle with lift heavy iron chains (6), hook with the lifting hook on the chain block on the wrecker (4) then and hang (57) suspension bracket that leads on the frame (5), and lead front portion or the rear portion that frame (5) is sling and is pulled vehicle by hanging, make to be pulled before the vehicle (or back) wheel built on stilts and together to travel with wrecker.Lift heavy iron chains (6) is made up of welding chainlet (61) and drag hook (62); its main effect is to cooperate to hang to lead frame (5) and hang and lead operation or be used alone as the lift heavy operation; mainly tangle to hang during use and lead frame with the chain block lifting hook; hang and lead grab (58) that hanging on the frame lead pivoted frame (54) two ends and will weld chain link stuck (and can conveniently take off) on the chainlet (61); the other end on the iron chains is then led bridge axle before the vehicle and freely pins with self chain hook (drag hook 62) around hanging; lifting hook hoists and drives and hangs rubber plate (55) the picking-up headstock (55 play load-bearing and safety guard-safeguard effect) that leads on the frame; together advance with wrecker, thereby realizing hanging leads operation.Do not need to hang and lead operation and only need drag when rescuing operation when damaging vehicle, can adopt the pull bar annex, be fixed in behind the wrecker towing hook and get final product operation with being pulled on the vehicle front tow hook.
