Abstract
The utility model discloses a self-unloading semi-trailer comprising a semi-trailer frame, a hydraulic lifting device, a cargo tank, a travelling mechanism and a guardrail, wherein the hydraulic lifting device and the cargo tank are arranged above the semi-trailer frame; the travelling mechanism and the guardrail are arranged below the semi-trailer frame; the hydraulic lifting device comprises a plurality of one-way hydraulic cylinders and bidirectional hydraulic cylinders; and the one-way hydraulic cylinders and the bidirectional hydraulic cylinders are arranged at equal intervals. Due to a reasonable hydraulic lifting design and the additional arrangement of the hydraulic lifting device, the part of the self-unloading semi-trailer, which is connected with the cargo tank, is enlarged when the hydraulic lifting device is used for unloading, supporting points are more uniform, and the operation is safer. Meanwhile, when the cargo carriage falls after the unloading operation is fulfilled, the bidirectional hydraulic cylinders can supply downward attractive force, so that the falling is accelerated, the waiting time is shortened, and the difference between the self-unloading semi-trailer and a common self-unloading semi-trailer is particularly obvious under shivery weather.
Description
Technical field
The utility model relates to a kind of superimposed trailer, especially a kind of self lighting type superimposed trailer.
Background technology
The self lighting type superimposed trailer is highway load transportation a kind of superimposed trailer commonly used, is made up of parts such as semi-trailer frame, hydraulic lifting device, loading space, guard rail and traveling geaies.Self lighting type superimposed trailer advantage is to load the loading space certain angle discharging of tumbling automatically, saves dumping time and labour power greatly, shortens the haul-cycle time, enhances productivity, and reduces traffic cost.But in actual the use, its container is after unsnatching material, and during the container landing, speed is extremely slow, and wait time is long, and under the cold snap situation, this kind situation is more serious.
The utility model content
The purpose that the utility model is carried is that a kind of self lighting type superimposed trailer that overcomes defective in the prior art will be provided.
The technical scheme of the utility model is: a kind of self lighting type superimposed trailer; Comprise semi-trailer frame; The hydraulic lifting that is arranged on semi-trailer frame top is put, loading space and traveling gear below semi-trailer frame and guard rail; Said hydraulic lifting device comprises unidirectional hydraulic actuating cylinder and the two-way hydraulic cylinder that several spacings equate, it is characterized in that: said hydraulic lifting device left and right sides above vehicle frame, its rollover direction one side hydraulic lifting device is a two-way hydraulic cylinder.
The utility model structure increases the hydraulic lifting device through rational hydraulic lifting design, makes the self lighting type superimposed trailer when hydraulic efficiency gear lifting discharging, and the position that is connected with loading space increases; POS is more even, and is safer, simultaneously discharging is intact close after, when loading space falls after rise; Two-way hydraulic cylinder can give gravitation downwards, and sinking speed is accelerated; Wait time shortens, and is especially under the cold snap situation, more obvious with common self-discharging semitrailer difference.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Following structure accompanying drawing and embodiment further specify utility model.
As shown in Figure 1, a kind of self lighting type superimposed trailer comprises semi-trailer frame, and the hydraulic lifting that is arranged on semi-trailer frame top puts 1, hydraulic lifting device 2, loading space 6 and traveling gear below semi-trailer frame 4 and guard rail 5.Said hydraulic lifting device 1 and 2 comprises unidirectional hydraulic actuating cylinder and the two-way hydraulic cylinder that several spacings equate respectively.Through rational hydraulic lifting design, increase hydraulic lifting device 2, make the self lighting type superimposed trailer when hydraulic efficiency gear lifting discharging, the position that is connected with loading space increases; POS is more even, and is safer, simultaneously discharging is intact close after, when loading space falls after rise; Hydraulic lifting device 2 is a two-way hydraulic cylinder, can give gravitation downwards, and sinking speed is accelerated; Wait time shortens, and is especially under the cold snap situation, more obvious with common self-discharging semitrailer difference.
The utility model is not limited to the described scope of the above-mentioned specific embodiment, and every conspicuous technology distortion of being done according to the utility model know-why all drops within the protection domain of the utility model.
