Description

Ballast transportation semitrailer

Technical Field

The utility model relates to a special type transportation semitrailer, concretely relates to ballast transportation semitrailer belongs to semitrailer technical field.

Background

At present, the frame of a domestic main semitrailer is in a double-side beam type framework structure, side beams on two sides of the semitrailer are mainly I-shaped steel with lower strength, when the semitrailer is used for transporting large-scale crane parts, concrete beams, steel bundles and other objects with higher density, multiple stress concentration is easily caused to cause frame deformation and cracking, the trailer part of the traditional semitrailer does not have steering capacity, and when the semitrailer is used for turning under a heavy load condition, tires are very seriously worn. It is worth mentioning that the ability to develop a high horsepower tractor for heavy transport is lacking in China, and the main multi-axle tractors still rely on import, so that most semitrailers often rely on the traction of high torque vehicles when traversing rough terrain under heavy loads.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a ballast transportation semitrailer who is equipped with central box cross-section beam type frame, hydraulic pressure turntable shaft steering system to the not enough of prior art existence.

The technical scheme of the utility model is that:

a ballast transportation semi-trailer comprises a pressure plate part, a frame, a cargo carrying platform, a ballast tank and a steering system of a rotary table shaft. The vehicle is characterized in that the vehicle frame is a central box-section beam type vehicle frame, a central main beam is of a hollow structure, rib plates are welded on two sides of the central main beam, the lower surface of the central main beam is connected with a turntable shaft steering system, a cargo platform in the front of the vehicle frame can be used for placing a ballast tank, and a frame type side beam structure is arranged on the periphery of the cargo platform; the cargo carrying platform mainly comprises six spliced wood boards, and two sides of each wood board of the cargo carrying platform are fixed by pressing plate pieces; the rotary disc shaft steering system comprises a hydraulic power system, a pull rod type mechanical system and a rotary disc type vehicle shaft, wherein the pull rod type mechanical system is hinged with the rotary disc type vehicle shaft, and the hydraulic power system directly provides rotary power for the rotary disc type vehicle shaft.

Furthermore, the frame is a central box-section beam type frame, a main beam is made of 16Mn, a chassis of a cargo carrying area at the front part of the frame is raised upwards, so that a gooseneck part is horizontal, and square through holes are uniformly formed in the peripheral edge beam of the frame; the cargo area mainly comprises six spliced wood boards and a main beam, and the wood boards are symmetrically distributed by taking the main beam as a central line.

Furthermore, the pressure plate piece is detachable, and its base welds in frame boundary beam upper surface.

Furthermore, the ballast tank is fixed on a cargo carrying platform at the front part of the frame through four square rubber pin shafts.

Further, the carousel in the carousel formula axletree is centerless carousel, and it welds directly on the girder lower surface.

The utility model has the benefits that:

the central box-section main beam is made of 16Mn and has high rigidity, when the vehicle body is under a heavy load condition, rib plates on two sides of the main beam can share most of the pressure of the cargo carrying platform and the main beam, the service life of the main beam is prolonged, and a chassis in a cargo carrying area at the front part of the vehicle frame is bulged upwards, so that the chassis has small sagging amount; the detachable design of clamp plate spare makes the operation when changing wood very convenient, and timber density is far less than steel, greatly reduced the car weight. Utilize carousel formula axletree to support the frame, with centerless carousel upper surface lug weld in the girder lower surface for load evenly distributed on the girder is on the slewing bearing, and because of the carousel diameter is less, the moment that the slewing bearing produced by internal force is not big, is difficult for arousing the great degree bending deformation of carousel, and this structural design can strengthen the automobile body and get stability in loading process. The through holes are uniformly distributed on the frame boundary beam and can be used for fixing the safety bandage; during heavy transportation, the pin shaft can be inserted into the pin hole of the side beam at the front part of the frame to fix the ballast tank, so that the pressure on the driving shaft of the tractor is increased to improve the traction force. Because the vehicle is provided with the turntable shaft steering system, the turning radius of the vehicle body can be effectively reduced, and the abrasion degree of tires is reduced.
