Description
Technical field
The utility model relates to a kind of special purpose engineering automobile, especially a kind of engineering truck that transports the use of cable laying cable.
Background technology
Along with 66 kilovolts and above power cable line in the urban distribution network come into operation on a large scale, the cable laying construction operation does not have special-purpose plant equipment basically, find out that from existing laying construction operation existing mode construction operation efficient is low, the bigger energy consumption of labour intensity is also bigger.
In 66 kilovolts and the operation of above power cable line laying construction, the cable disk loading and unloading, need crane before and after transhipment, to participate in, particularly use crane can influence urban transportation at the scene, and each drum needs to use crane 2 times at the scene, move down and bring up to, each crane marches into the arena to leave needs more than 20 minute, greatly influences the social benefit and the image of traffic and reduction power engineering.
The cable construction of existing shop mainly is: at first entrucking, in the unit in charge of construction warehouse, with crane cable hank is lifted on the transport vehicle, this moment, the warehouse need hold crane and transport vehicle than large space, if open area then needs bigger place, in the city, be difficult to accomplish; Next is fixing, the cable hank colligation is fixed on the transport vehicle, because cable hank generally all is the weight more than 5 tons, on General-Purpose Carrier, there is not special fixing device, fixing by artificial binding, labour intensity is big on the one hand, and firmness judges that by experience fail safe can not guarantee fully on the other hand; Be transportation once more, by transport vehicle cable hank is transported to the scene, because transport vehicle is the universal product, when the cable hank that general diameter is 2.8 meters transports, the car load height is just above 4 meters, do not meet relevant road driving rules, adding that the cable hank reliability of fixation can't guarantee fully, therefore needing to plan travel route before the transportation, needing the multi-section automobile to set out on a journey simultaneously in the transportation, the front needs car and clears the way, intermediate rear face need be observed with car, and travel speed is slower, takies a large amount of path resources in the city, operating efficiency is extremely low, and environmental impact is big; Be to unload in the scene once more, cable hank can only be unloaded with autocrane in the scene, generally all is with 25 tons of autocranes, length is more than 10 meters, and the horizontal span of supporting leg is general more than 6.6 meters, need seal operation when generally constructing, about 20 minutes of time, seriously influence environment like this in the city; The back is the frame cable hank, and cable hank unloads the back crane and drives away, and manually cable hank is pushed into correct position and direction, wear central shaft, this is general more than 110 millimeters, about 2 meters of length, about 150 kilograms of weight, by manual operation, the scene also needs artificial assembling cable disc carrier, will put on the cable hank of axle again and erect with jack, also needs manually to adjust the level of cable hank, this process labour intensity is big, and artificial demand is more; Be to be only payout operations at last.
Patent Office of the People's Republic of China has announced a CN2052377U patent February 7 nineteen ninety, name is called self-loading and unloading type cable jiggering, this car is connected vehicle frame by upper bearing plate, lower support plate, and the top of upper bearing plate is provided with a groove, and the round thick stick in the middle of the cable hank is stuck in the groove, this car is exactly to adopt artificial mode, efficient is lower, and fail safe is not high, so big weight, topple over easily, the support of wheel is also unstable.
Summary of the invention
The utility model has solved does not have special equipment and some links adopts manual operation to cause efficient low in the prior art, the shortcoming that fail safe is low provides a kind of employing mechanical structure, efficient height, safe cable laying engineering truck.
It is big that the utility model has also solved in the prior art labor strength, need during use to cooperate in many ways and cause the high shortcoming of the time-consuming energy consumption of taking a lot of work, provide a kind of and can finish transportation separately and lay the cable laying engineering truck of function, saving of work and time cuts down the consumption of energy and reduces environmental impact.
It is little that the utility model has also solved the cable hank weight of carrying in the prior art, and might cause the shortcoming of superelevation, and a kind of cable laying engineering truck is provided, and can carry heavier cable hank, the height in the time of can also reducing transportation simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cable laying engineering truck, comprise cable placement crossbeam, be arranged on cable hank fixture and retaining mechanism on the crossbeam, it is characterized in that crossbeam connects automobile chassis, be fixed with on the crossbeam and drive rotatable turntable, be hinged with rotatable crane arm structure on the turntable, fixture is arranged on the end of crane arm structure, and retaining mechanism comprises connecting rod and passes cable hank and hold the depression bar of cable hank tightly.Cable hank is fixed on the end of crane arm structure by fixture, cable hank is sling by crane arm mechanism, rotate by turntable again and lift by crane on the crossbeam, cable hank is fixed by retaining mechanism after being placed on the crossbeam, these all actions all are to realize by machinery or hydraulic pressure, therefore the greater weight cable hank can be realized remote transportation, also can easily lay at the scene, improved efficient, also alleviate working strength of workers, all adopted the mechanical transport lifting, just saved workman's carrying, improved fail safe, prevent the danger of toppling over, other auxiliary equipment have been saved in the work that this engineering truck just can be finished transportation and lay simultaneously, saved resource, also reduce simultaneously cost, and the area that can reduction equipment when laying occupies, can reduce the probability of traffic jam in the inside, urban district, need not wait for that also other equipment are in place, saved the plenty of time.
