Abstract
The utility model relates to a platform widening technology for a low flatbed semitrailer, and specifically relates to a platform widening structure for a low flatbed semitrailer. The platform widening structure for a low flatbed semitrailer is arranged on a frame of a semitrailer and characterized in that an upper fixed base and a lower fixed base are welded from top to bottom on the frame in sequence. The lower fixed base is provided with a semicircular notch, a rotating shaft is arranged between the upper and lower fixed bases, a widening bracket is welded on the rotating shaft and a pin pole is arranged at the bottom of the rotating shaft. In the platform widening structure for a low flatbed semitrailer provided by the utility model, the rotating shaft can be installed freely, thereby not only guaranteeing the strength of the frame, but also realizing free-disassembly.
Description
Technical field
The utility model relates to a kind of low flat bed semi trailer platform and widens technology, specifically relates to a kind of low flat bed semi trailer platform and widens mechanism.
Background technology
The part Engineering low flat bed semi trailer that uses on the market now need be widened active platform for adapting to the transportation under the specific condition, and is not ultra wide when normally using for the assurance vehicle simultaneously, needs to widen support and makes telescopic or rotary.When widening support and be rotational structure, for fixing S. A. will so both reduce frame intensity in frame perforate up and down,, rotating shaft and frame can't dismantle after welding simultaneously, cause inconvenient maintenance.
The utility model content
To the technical matters that exists in the prior art, the purpose of the utility model is to provide a kind of low flat board of Engineering of realizing to widen the platform that platform freely dismantles and widen mechanism.
The technical scheme that the utility model adopts is following:
A kind of low flat bed semi trailer platform is widened structure, is located on the superimposed trailer frame, it is characterized in that, frame is welded with upper fixed seat, lower fixed seat from top to bottom successively, and lower fixed seat has semicircular notch; Between upper and lower permanent seat, rotating shaft is installed, is welded with in the rotating shaft and widens support, the rotating shaft bottom has pin shaft hole.
The said support top of widening also is equipped with and widens base plate.
The utility model low flat bed semi trailer platform is widened structure, and rotating shaft can freely be installed, and both can guarantee frame intensity, can realize again freely dismantling.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that the utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
Among Fig. 1: the 1-upper fixed seat, the 2-lower fixed seat, the 3-rotating shaft, 4-widens support, the 5-pin shaft hole, 6-widens base plate, 7-superimposed trailer frame.
The specific embodiment
As shown in Figure 1, the low flat bed semi trailer platform is widened structure, is welded with upper fixed seat 1, lower fixed seat 2 from top to bottom successively at low flat bed semi trailer frame 7; Lower fixed seat 2 has semicircular notch, and rotating shaft 3 upper ends penetrate in the upper fixed seat 1, and the lower end is through in lower fixed seat 2 semicircular notch; Rotating shaft 3 bottoms have pin shaft hole 5, and during work, it is spacing to utilize bearing pin countershaft 3 to carry out; Neither hinder its rotation, can prevent that again rotating shaft 3 from deviating from semicircular notch.
In rotating shaft 3, be welded with and widen support 4, widening support 4 is the frameworks that are processed to form by several steel, lay on the top of widening support 4 assembly welding good widen base plate 6.
Claims (2)
1. a low flat bed semi trailer platform is widened structure, is located on the superimposed trailer frame, it is characterized in that, frame is welded with upper fixed seat, lower fixed seat from top to bottom successively, and lower fixed seat has semicircular notch; Between upper and lower permanent seat, rotating shaft is installed, is welded with in the rotating shaft and widens support, the rotating shaft bottom has pin shaft hole.
2. low flat bed semi trailer platform according to claim 1 is widened structure, it is characterized in that, the said support top of widening also is equipped with and widens base plate.
