Description

Technical Field

[0001] This utility model relates to the field of cryogenic semi-trailer manufacturing technology, and in particular to a connection device between the traveling mechanism and the tank of a cryogenic semi-trailer. Background Technology

[0002] Since the invention of high-vacuum multi-layer insulated cryogenic tank trucks in my country in the 1990s, high-vacuum multi-layer insulation technology has gradually matured. With the sustained and rapid development of the national economy and the continuous improvement of industrialization, the market demand for gases is increasing. Cryogenic liquefied gas transportation, with its advantages of low cost, convenience, high product purity, and easy liquid-gas conversion, has experienced rapid development. The connection device between the cryogenic semi-trailer and the tank body is an important component of cryogenic semi-trailers. In existing connection devices, multiple web plates are fixed to the running gear of the cryogenic semi-trailer with bolts. When the web plates crack after long-term use and need replacement, installation and disassembly are inconvenient, presenting a drawback. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems by providing a connection device between the traveling mechanism and the tank of a cryogenic semi-trailer.

[0005] A long, open-end box is mounted on the chassis of a cryogenic semi-trailer, and the long, open-end box has several openings.

[0006] A cover plate is detachably mounted on the long plate box;

[0007] Several web plates with one side curved, each having a base, and ear plates on both sides of the base.

[0008] Preferably, the long plate box is provided with a number of insertion rods, and each of the bases is provided with insertion holes.

[0009] Preferably, the insertion rod is provided with a plurality of elastic balls.

[0010] Preferably, one end of the insertion rod is rounded to form an arc shape.

[0011] Preferably, the long plate box is provided with a number of reinforcing plates.

[0012] The beneficial effect of this utility model is that the web plate can be replaced quickly. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 7 A connection device between the traveling mechanism and the tank of a cryogenic semi-trailer, comprising:

[0023] A long plank box 10 with one end open is mounted on the chassis of a cryogenic semi-trailer, and the long plank box 10 has a plurality of openings 101.

[0024] The cover plate 2 is detachably mounted on the long plate box 10;

[0025] Several web plates 3 with one side curved are provided, each with a base 301. Ear plates 3011 are provided on both sides of the base 301. In this invention, the long plate box 10 is fixed to the traveling mechanism of the cryogenic semi-trailer by welding or bolting. The base 301 is installed at the opening 101, and then the cover plate 2 is fixed to the long plate box 10. One side of the cover plate 2 contacts one side of the base 301, and the ear plates 3011 contact the upper inner wall of the long plate box 10. The web plates 3 are then installed on the long plate box 10. When the web plates 3 crack after prolonged use and need replacement, the cover plate 2 is removed, and the web plates 3 are pulled out for replacement, thus achieving quick replacement of the web plates 3. Specifically, the cover plate 2 is connected to the long plate box 10 by bolts; the traveling mechanism is a chassis.

[0026] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0027] In this embodiment, the long plate box 10 is provided with a plurality of insert rods 102, and each of the plurality of bases 301 is provided with an insertion hole 3012. When one of the web plates 3 is damaged, since the web plate 3 cooperates with the insert rod 102 through the insertion hole 3012, after the cover plate 2 is removed, the web plate 3 is prevented from moving toward the opening of the long plate box 10.

[0028] In this embodiment, the insertion rod 102 is provided with a plurality of elastic balls 1021. The insertion hole 3012 cooperates with the insertion rod 102 to compress the elastic balls 1021, increasing the friction between the two and preventing the base 301 from moving easily.

[0029] In this embodiment, one end of the insertion rod 102 is rounded to form an arc shape, which facilitates its mating with the insertion hole 3012.

[0030] In this embodiment, the long plate box 10 is provided with a plurality of reinforcing plates 103 to improve the strength of the long plate box 10.

[0031] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
