Description

Technical Field

[0001] The utility model relates to the technical field of semi-trailers, and specifically, to a novel rotatable cage-type spare tire rack. Background Art

[0002] When a semi-trailer is running, it usually needs to be equipped with at least two spare tires to meet the basic needs and ensure that the spare tire can be replaced in time when a flat tire accident occurs. However, for a semi-trailer with a smaller wheelbase, due to space limitations, the traditional spare tire rack cannot be applied, and more than two spare tires cannot be placed on the actual vehicle, which cannot meet the basic needs.

[0003] Moreover, the traditional cage-type spare tire rack cannot adjust the installation structure, cannot adapt to the semi-trailer beams with different spacings, has weak versatility, and is not convenient to disassemble.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide a novel rotatable cage-type spare tire rack. The utility model is installed under the semi-trailer beam by a hanging structure, can meet the installation of at least two spare tires, can reasonably use the space of the semi-trailer beam, occupies a small space of the semi-trailer beam, is convenient to disassemble, adapts to the semi-trailer beams with different spacings, and has strong versatility.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a novel rotatable cage-type spare tire rack, including a spare tire rack and two hanging racks;

[0007] The spare tire rack is horizontally arranged under the semi-trailer beam in the left-right direction and is used for installing at least two spare tires;

[0008] The two hanging racks have the same structure and are symmetrically and rotatably installed on the spare tire rack, and are used for hanging the spare tire rack. The upper end of the left hanging rack is hinged to the left semi-trailer beam, and the upper end of the right hanging rack is hinged to the right semi-trailer beam.

[0009] Based on the above, the spare tire rack includes two spare tire transverse brackets, the two spare tire transverse brackets are arranged at intervals front and back and are horizontally arranged under the semi-trailer beam in the left-right direction. At least three spare tire longitudinal brackets arranged at intervals left and right are fixedly connected between the two spare tire transverse brackets. A spare tire longitudinal support group for fixing the spare tire is arranged between adjacent two spare tire longitudinal brackets, and the spare tire longitudinal support group is fixedly connected between the two spare tire transverse brackets.

[0010] Based on the above, the spare tire longitudinal support group includes two first spare tire longitudinal supports arranged at intervals left and right, and a second spare tire longitudinal support arranged in the middle of the two first spare tire longitudinal supports. The first spare tire longitudinal supports and the second spare tire longitudinal support are both fixedly connected between two spare tire transverse brackets. A first bolt hole is provided in the middle of the first spare tire longitudinal support, and two second bolt holes are provided on the second spare tire longitudinal support at intervals front and back and symmetrically. The distance between the two first bolt holes is equal to the distance between the two second bolt holes.

[0011] Based on the above, the hanger is a U-shaped part with the open side facing upward. The lower horizontal section of the hanger is horizontally placed below the two spare tire transverse brackets along the front-back direction. The length of the lower horizontal section of the hanger is greater than the distance between the two spare tire transverse brackets. Two sleeve round steels are coaxially sleeved on the lower horizontal section of the hanger at intervals front and back. The two sleeve round steels are respectively fixedly installed at the bottoms of the two spare tire transverse brackets. The lower horizontal section of the hanger is rotatably connected with the two sleeve round steels. Two limiting blocks are also fixedly provided on the lower horizontal section of the hanger at intervals front and back. The two limiting blocks are located between the two sleeve round steels. The front limiting block is close to the rear end of the front sleeve round steel, and the rear limiting block is close to the front end of the rear sleeve round steel. The front vertical section of the hanger is located in front of the front spare tire transverse bracket, and the rear vertical section of the hanger is located behind the rear spare tire transverse bracket. Hinge supports are hinged to the upper ends of the front vertical section and the rear vertical section of the hanger through hinge structures;

[0012] The two hinge supports on the left are welded to the left semi-trailer beam at intervals front and back, and the two hinge supports on the right are welded to the right semi-trailer beam at intervals front and back.

[0013] Based on the above, both the hanger and the sleeve round steel are seamless pipes.

[0014] Based on the above, the spare tire transverse bracket, the spare tire longitudinal bracket, the first spare tire longitudinal support and the second spare tire longitudinal support are all channel steels.

[0015] Based on the above, a support plate is welded to the top of each of the two sleeve round steels. The front support plate is welded to the bottom of the front spare tire transverse bracket, and the rear support plate is welded to the bottom of the rear spare tire transverse bracket. Reinforcement plates are welded between the left and right sides of the front sleeve round steel and the front spare tire transverse bracket and between the left and right sides of the rear sleeve round steel and the rear spare tire transverse bracket.

[0016] Based on the above, the front hinge structure includes a pin shaft. The pin shaft is a tube shaft structure. The pin shaft is fixedly connected to the upper end of the front vertical section of the hanger and its center line is horizontally arranged along the front-back direction. The pin shaft is hinged to the front hinge support through a split pin.

[0017] The present utility model has substantial features and progress compared with the prior art. Specifically, the present utility model has the following advantages:

[0018] (1) The spare tire rack is installed below the semi-trailer girder in a hanging structure, which can meet the installation of at least two spare tires, make reasonable use of the space of the semi-trailer girder, and only need to fixedly install a hinge support on the semi-trailer girder, occupying a small space of the semi-trailer girder, and can reasonably utilize the space that cannot be used by the original spare tire rack structure;

[0019] (2) The spare tire rack is convenient to disassemble. If not in use, the hinge structure can be removed, so that the hanging bracket can be separated from the hinge support, and then the spare tire rack can be disassembled from the semi-trailer girder;

[0020] (3) The spare tire rack can rotate relative to the hanging bracket. In this way, the rotation positions of the two hanging brackets can be adjusted according to the distance between the semi-trailer girders, and then the spare tire rack can be adapted to semi-trailer girders with different distances, ensuring that the spare tire rack remains horizontal and has strong versatility;

[0021] (4) The hinge support is connected to the hanging bracket through a hinge structure, so that the hinge support can adjust its orientation according to the rotation position of the hanging bracket, ensuring that the hinge support is parallel to the semi-trailer girder, facilitating welding, and better adapting to the semi-trailer girder;

[0022] (5) When placing the spare tire, according to the position and angle of the prefabricated holes on the spare tire, bolts can be used to fixedly connect the spare tire to the first bolt holes on the two first spare tire longitudinal braces in the corresponding spare tire longitudinal brace group, or to the two second bolt holes on the second spare tire longitudinal brace in the corresponding spare tire longitudinal brace group, reducing excessive adjustment and movement of the spare tire, reducing labor intensity, and making the fixed installation of the spare tire convenient.

[0030] The technical solution of the present utility model will be further described in detail below through specific implementation modes.

[0031] As Figures 1-6 shown, a new type of rotatable cage-type spare tire rack includes a spare tire rack and two hangers 1;

[0032] The spare tire rack is horizontally arranged below the semi-trailer girder 2 in the left-right direction and is used for installing at least two spare tires 3;

[0033] The two hangers 1 have the same structure and are symmetrically and rotatably installed on the spare tire rack in the left-right direction for lifting the spare tire rack. The upper end of the left hanger 1 is hinged to the left semi-trailer girder 2, and the upper end of the right hanger 1 is hinged to the right semi-trailer girder 2.

[0034] The spare tire rack is hung below the semi-trailer girder 2 through the hanger 1, which can meet the installation of at least two spare tires 3 and can reasonably utilize the space that cannot be used by the original spare tire rack structure.

[0035] In this embodiment, the spare tire rack includes two transverse spare tire brackets 4. The two transverse spare tire brackets 4 are arranged at intervals front and back and are horizontally arranged below the semi-trailer girder 2 in the left-right direction. Three longitudinal spare tire brackets 5 arranged at intervals left and right are fixedly connected between the two transverse spare tire brackets 4. A spare tire brace group for fixing the spare tire 3 is arranged between adjacent two longitudinal spare tire brackets 5, and the spare tire brace group is fixedly connected between the two transverse spare tire brackets 4. Then there are two spare tire brace groups in this embodiment. In this way, the spare tire rack of this embodiment can install two spare tires 3. In other embodiments, more than two spare tire brace groups can be fixedly arranged between the two transverse spare tire brackets 4 as needed so as to be able to fixedly install more than two spare tires 3.

[0036] In this embodiment, the spare tire longitudinal support group includes two first spare tire longitudinal supports 6 arranged at intervals left and right and a second spare tire longitudinal support 7 arranged in the middle of the two first spare tire longitudinal supports 6. Both the first spare tire longitudinal support 6 and the second spare tire longitudinal support 7 are fixedly connected between two spare tire transverse brackets 4. A first bolt hole 8 is provided in the middle of the first spare tire longitudinal support 6, and two second bolt holes 9 that are spaced front and back and symmetric are provided on the second spare tire longitudinal support 7. The distance between the two first bolt holes 8 is equal to the distance between the two second bolt holes 9. When the spare tire 3 is placed, if two of the prefabricated holes on the spare tire 3 are respectively vertically aligned with the first bolt holes 8 on the two first spare tire longitudinal supports 6 in the corresponding spare tire longitudinal support group, bolts are used to fixedly connect the spare tire 3 to the first bolt holes 8 on the two first spare tire longitudinal supports 6 in the corresponding spare tire longitudinal support group. If two of the prefabricated holes on the spare tire 3 are respectively vertically aligned with the two second bolt holes 9 on the second spare tire longitudinal support 7 in the corresponding spare tire longitudinal support group, bolts are used to fixedly connect the spare tire 3 to the two second bolt holes 9 on the second spare tire longitudinal support 7 in the corresponding spare tire longitudinal support group, reducing excessive adjustment and movement of the spare tire 3, reducing labor intensity, and facilitating the fixed installation of the spare tire 3.

[0037] In this embodiment, the hanger 1 is a U-shaped member with the open side facing upward. The lower horizontal section of the hanger 1 is horizontally placed below the two spare tire transverse brackets 4 in the front-back direction. The length of the lower horizontal section of the hanger 1 is greater than the distance between the two spare tire transverse brackets 4. Two sleeve round steels 10 spaced front and back are coaxially sleeved on the lower horizontal section of the hanger 1. The two sleeve round steels 10 are respectively fixedly installed at the bottoms of the two spare tire transverse brackets 4. The lower horizontal section of the hanger 1 is rotatably connected to the two sleeve round steels 10. Two limiting blocks 11 spaced front and back are also fixedly provided on the lower horizontal section of the hanger 1. The two limiting blocks 11 are located between the two sleeve round steels 10. The front limiting block 11 is close to the rear end of the front sleeve round steel 10, and the rear limiting block 11 is close to the front end of the rear sleeve round steel 10. The limiting blocks 11 can ensure restricting the relative position of the hanger 1 during the rotation of the hanger 1; the front vertical section of the hanger 1 is located in front of the front spare tire transverse bracket 4, and the rear vertical section of the hanger 1 is located behind the rear spare tire transverse bracket 4. The upper ends of the front vertical section and the rear vertical section of the hanger 1 are respectively hinged with hinge supports 12 through hinge structures;

[0038] The two hinge supports 12 on the left side are welded to the left semi-trailer frame 2 at intervals front and back, and the two hinge supports 12 on the right side are welded to the right semi-trailer frame 2 at intervals front and back. The hanger 1 can rotate relative to the spare tire rack through the sleeve round steel 10. In this way, the rotation positions of the two hangers 1 can be adjusted according to the distance between the semi-trailer frames 2, so as to adapt to the semi-trailer frames 2 with different distances, ensure that the spare tire rack remains horizontal, and has strong versatility. At the same time, the hinge support 12 can adjust its orientation according to the rotation position of the hanger 1 to ensure that the hinge support 12 is parallel to the semi-trailer frame 2, which is convenient for welding and better adapts to the semi-trailer frame 2. Moreover, when installing this spare tire rack, only the corresponding hinge support 12 needs to be fixedly installed on the semi-trailer frame 2, which occupies a small space on the semi-trailer frame 2. The hanger 1 and the hinge support 12 are connected by a hinge structure. If the spare tire rack is not used, the hinge structure can be removed, so that the hanger 1 and the hinge support 12 can be separated, and then the spare tire rack can be disassembled from the semi-trailer frame 2, which is convenient for disassembly.

[0039] In this embodiment, both the hanger 1 and the sleeve round steel 10 are seamless pipes.

[0040] In this embodiment, the spare tire transverse bracket 4, the spare tire longitudinal bracket 5, the first spare tire longitudinal brace 6 and the second spare tire longitudinal brace 7 are all channel steels.

[0041] In this embodiment, a support plate 13 is welded to the top of each of the two sleeve round steels 10. The front support plate 13 is welded to the bottom of the front spare tire transverse bracket 4, and the rear support plate 13 is welded to the bottom of the rear spare tire transverse bracket 4. Reinforcement plates 14 are welded between the left and right sides of the front sleeve round steel 10 and the front spare tire transverse bracket 4 and between the left and right sides of the rear sleeve round steel 10 and the rear spare tire transverse bracket 4.

[0042] In this embodiment, the front hinge structure includes a pin shaft 15. The pin shaft 15 is a pipe shaft structure. The pin shaft 15 is fixedly connected to the upper end of the front vertical section of the hanger 1 and its center line is horizontally arranged in the front-rear direction. The pin shaft 15 is hinged to the front hinge support 12 through a bolt pin 16. The bolt pin 16 can be easily disassembled and has a simple structure.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
