Has the advantages that: the angle iron guardrail is characterized by stable structure and light weight, is completely suitable for the existing operation environment of a wharf, can bear frequent jolt, and obviously improves the cracking condition of the guardrail and a support frame.
Description
Technical Field
The utility model belongs to the technical field of trailers, and particularly relates to a light semitrailer guardrail.
Background
The container tractor mainly engages in the transfer business of the container at the front edge of the wharf, and the trailer which is pulled by the container tractor frequently suffers from the impact and vibration of heavy load, so that the original guardrail of the trailer is frequently cracked and needs to be frequently maintained. The main reasons for the analysis are: the structure of the existing trailer guardrail adopts a square tube to be welded into a guardrail frame, then an iron plate trailer plate structure is welded, and the guardrail support frame adopts an iron tube, so that the whole weight of the guardrail is larger. The wharf operation is characterized in that the wharf operation is frequently subjected to container loading and unloading load impact, the number of road surface field bridge track beams on a wharf site is large, and the trailer is frequently jolted. The above causes the guardrail and the support frame to crack. At present, the method adopts reinforcement welding, the method addresses both the symptoms and the root causes, the weight of the guardrail can be further increased by frequent reinforcement welding, and the guardrail finally cracks under the frequent bumping condition.
Port logistics urgently requires a light semitrailer guardrail which adapts to the existing operation environment of a wharf and can bear frequent jolts.
SUMMERY OF THE UTILITY MODEL
The utility model provides a light semitrailer guardrail for overcoming the defects in the prior art, which adopts a guardrail with an angle steel structure, is light and stable in weight, and can bear frequent jolts when being adapted to the existing operation environment of a wharf.
The utility model aims to achieve the aim, and the light semitrailer guardrail is realized by the following technical scheme, comprises a left guardrail assembly and a right guardrail assembly which are formed by a support frame, a guardrail and a mounting plate, and is characterized in that: the guardrail includes entablature, bottom end rail and five longerons and constitutes two violently five vertical frame structures, entablature, bottom end rail and longeron adopt the angle steel to make, the support frame includes upper bracket frame and bottom end rail, upper bracket frame and bottom end rail adopt the angle steel to weld respectively into the triangle-shaped structure, and the hypotenuse welding of two triangles constitutes the quadrangle support frame, quadrangle support frame front end welds with guardrail entablature and bottom end rail respectively, and quadrangle support frame rear end welds with the mounting panel, the mounting panel passes through bolt and trailer rigid coupling.
The angle steel adopts equal-edge angle steel, and the edge width multiplied by the edge thickness of the equal-edge angle steel is 40mm multiplied by 4 mm.
The length of the guardrail is 5M-6M.
Has the advantages that: compared with the prior art, the angle iron guardrail is characterized by stable structure and light weight, is completely suitable for the existing operation environment of a wharf and can bear frequent jolt. After a period of use observation, the condition of the cracking of the guardrail and the support frame is obviously improved. The batch reconstruction is simple in working and can be carried out on a large scale. The single-trailer reconstruction cost is not very high, the comprehensive accounting cost for reconstructing each trailer is only about 600 yuan, and the maintenance cost is greatly reduced.
Drawings
FIG. 1 is a schematic diagram of the present invention.
In the figure: 1. the support frame, 2, guardrail, 3, mounting panel, 4, entablature, 5, bottom end rail, 6, longeron, 7, upper bracket, 8, under bracing frame, 9, semitrailer automobile body.
Detailed Description
The following detailed description of the embodiments provided in accordance with the present invention is provided in conjunction with the preferred embodiments: see the figure in detail, this embodiment provides a light-duty semitrailer guardrail, constitute left and right sides guardrail assembly including support frame 1, guardrail 2 and mounting panel 3, the guardrail includes entablature 4, bottom end rail 5 and five longerons 6 and constitutes two horizontal five vertical frame structures, entablature, bottom end rail and longeron adopt the angle steel to make, the support frame includes upper bracket 7 and bottom support 8, upper bracket and bottom support adopt the angle steel to weld respectively into the triangle-shaped structure, and the hypotenuse welding of two triangles constitutes the quadrangle support frame, quadrangle support frame front end welds with guardrail entablature and bottom end rail respectively, and quadrangle support frame rear end and mounting panel welding, the mounting panel passes through bolt and semitrailer automobile body 9 rigid coupling. The angle steel adopts equal-edge angle steel, and the edge width multiplied by the edge thickness of the equal-edge angle steel is 40mm multiplied by 4 mm. The length of the guardrail is 5M-6M.
Material selection for this example: the material adopts equilateral angle steel 40mm multiplied by 4mm as a frame to replace the original square tube material frame, so that the total weight can be reduced;
and (4) guardrail: the guardrail pattern is changed into a two-transverse five-longitudinal structure from an original three-transverse five-longitudinal structure, and the angle steel has the structural characteristic of being triangular, so that the stability is superior to that of a square tube, and the guardrail is not easy to deform and crack. Can reduce a crossbeam in the middle of, further lighten self weight, guarantee original safeguard effect simultaneously, five longitudinal structure keep unchangeable can effectually prop up two crossbeams and guarantee that guardrail overall structure is indeformable in the operation.
A support frame: the guardrail support frame changes original pipe material into equilateral angle steel equally, and equilateral angle steel can avoid the problem that the pipe fracture often appears in-service use, and the support frame adopts two triangle-shaped butt welds to constitute quadrangle structure, and mutual support stability is stronger.
4. Calculating the materials: the length of the guardrail of the embodiment is about 5.5M, and the left and right guardrails and the support frame share about 35.2M of angle steel. The cost of each trailer is comprehensively calculated to be about 600 yuan by calculating about 97 yuan for each existing 6m equal-edge angle steel.
The above detailed description of the light semitrailer guard rail, with reference to the embodiments thereof, is illustrative and not restrictive, and several embodiments thereof are possible within the limits set forth, so that variations and modifications may be effected without departing from the general inventive concept within the scope thereof.
