Description

Self-unloading semitrailer

The technical field is as follows:

the invention relates to the technical field of bulk cargo transportation equipment, in particular to a self-discharging semitrailer.

Background art:

the self-unloading semi-trailer is mainly used for transporting bulk cargo such as grain, ore, coal, steel and the like. The self-discharging semi-trailer mainly comprises a frame, carriages arranged on two sides of the frame, a chain type discharging mechanism for discharging materials arranged on the frame, a front baffle plate arranged at the front end of each carriage, a rear door arranged at the rear part of each carriage, a suspension and wheels arranged below the frame, although the prior self-discharging semi-trailer can basically meet the transportation requirements, however, in practical use, some outstanding problems exist, firstly, the structural strength needs to be improved, the structural strength of the dump semi-trailer mainly depends on the frame, the carriage and the connection between the frame and the carriage, most of the longitudinal beams in the existing frame adopt an approximate C-shaped structure, the structure has general bearing capacity, is easy to deform under the action of large impact and load, in addition, the existing carriage mainly adopts a flat plate or a corrugated plate, the structural design of the carriage has poor impact resistance and extrusion capability, and the carriage is easy to deform after being used for a long time, so that the welding position of the carriage and a frame is welded. The existing structural design of the frame and the carriage causes the problem that the frame and/or the carriage are deformed in actual use, and the welding position is easily welded once the frame and/or the carriage are deformed, the structural strength of the whole frame is realized mainly by welding connection, so that the welding position seriously influences the safety of the whole frame, and in addition, the longitudinal beam in the frame is deformed to cause the increase of a gap between a conveying belt and the longitudinal beam and the leakage of materials from the gap between the conveying belt and the longitudinal beam. Secondly, the chain type discharging mechanism is inconvenient to maintain and repair, and because the chain type discharging mechanism in the self-discharging semitrailer is arranged at the bottom of the carriage, the chain and the conveying belt on the chain bear the impact of materials in the whole carriage and drag the materials to horizontally move for discharging, the chain is easy to damage under the special working environment, and therefore the chain is vital to daily maintenance and repair of the chain, and then the chain is not maintained timely due to the fact that the prior art means mainly depends on manual lubrication and maintenance, and the maintenance effect is poor. In addition, all the conveying belts need to be dismantled during maintenance of the chains, but the existing conveying belts are mainly installed on the cross beam through a plurality of bolts, and the cross beam is welded on the chains, so that hundreds of bolts and nuts need to be dismantled and installed when the conveying belts are dismantled at every time, and the operation is very complicated. Thirdly, current back door opening and closing mechanism exposes in the outside, because dump semi-trailer operational environment is relatively poor, the hydro-cylinder is very easily contaminated, and current back door opening and closing mechanism does not have self-locking function in addition, and the reliability is general when leading to the back door to close.

The utility model provides a self-discharging semitrailer working process of unloading:

when the back door is opened: the oil cylinder 503 is started, the oil cylinder 503 firstly drives the lifting slide base 502 to move downwards, the lifting slide base 502 drives the lock plate 505 on the lifting slide base to move downwards when moving downwards, so that the lock plate 505 is separated from the clamp plate 507 and is not self-locked, the lifting slide base 502 stops moving downwards when the upper limit plate 5022 in the lifting slide base 502 is contacted with the guide vertical plate 5012, the lock plate 505 is completely separated from the clamp plate 507 at the moment, then the oil cylinder 503 continues to work, at the moment, the guide vertical plate 5012 limits the lifting slide base 502 (which is equivalent to that the bottom of the oil cylinder 503 cannot move and can only rotate) through the upper limit plate 5022, so the oil cylinder 503 can only drive the rear door 206 to rotate and open completely when the oil cylinder 503 reaches the maximum stroke.

Unloading: when the rear door 206 is completely opened, the motor 306 drives the driving sprocket 303 to rotate through the driving shaft 305, the driving sprocket 303 drives the chain 302 to move towards the rear door 206 along the chain guide rail 301, the conveying belt 307 on the chain 302 drives the material on the chain to be discharged in a translation manner, when the conveying belt 307 reaches the position of the rear door 206, the free end of the conveying belt is dropped under the self gravity, the material is completely discharged, then the conveying belt 307 continues to operate, when the conveying belt 307 operates to the driven sprocket 304, the conveying belt starts to be attached to the chain 302, and when the conveying belt 307 operates above the chain 302, the conveying belt returns to the horizontal state to continue to discharge.

When the back door is closed, after unloading is finished, the oil cylinder 503 is decompressed, the back door 206 falls back under the action of self gravity, after the back door 206 is completely closed, the oil cylinder 503 is started to retract, the lifting slide seat 502 is driven to move upwards when the oil cylinder 503 retracts, the locking plate 505 on the lifting slide seat 502 is driven to move upwards while the lifting slide seat 502 moves upwards, when the locking plate 505 is in contact with the clamping plate 507, the locking plate 505 stops moving upwards, at the moment, the oil cylinder 503 is completely retracted and reset, and the self-locking of the back door 206 is realized by the locking plate 505 and the clamping plate 507.
