Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit accessories, and in particular relates to a rail transit floor structure and a rail transit floor. Background Art

[0002] Traditional rail transit floors typically consist of adhesive-bonded aluminum honeycomb flooring, brazed aluminum honeycomb flooring, composite material flooring, and plywood flooring. These floors are typically bolted to the vehicle chassis. After installation, rubber or PVC floor coverings are applied uniformly. During the vehicle's service life, if a section of the floor collapses, delaminates, or peels, all the coverings must be removed, the bolts securing the damaged floor replaced, and the covering reapplied. This is a cumbersome and material-intensive process. Furthermore, when additional equipment needs to be installed on the vehicle chassis, the flooring must be cut and bolted back in place, making installation time-consuming and labor-intensive, and resulting in poor usability and maintainability.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figure 1 、 2 As shown, the utility model provides a rail transit floor structure, which includes a floor decoration layer 100, a floor body 200 and a plurality of connecting devices 300; the floor decoration layer 100 covers the upper side of the floor body 200; the connecting device 300 includes a connecting rod 310 and a connecting seat 320; the first end 311 of the connecting rod is connected to the lower side of the floor body 200, and the second end 312 of the connecting rod is provided with a receiving cavity 313, and the connecting seat 320 includes a spherical joint 321 and a base 322, and the spherical joint 321 is provided on the upper side of the base 322; the spherical joint 321 is correspondingly accommodated in the receiving cavity 313, and the second end 312 of the connecting rod is correspondingly matched with the connecting seat 320 to form a connection. The opening width of the accommodating cavity 313 is larger than the diameter of the ball joint 321. This rail transit floor structure directly covers a single floor main body 200 with a floor decoration layer 100, such as a plating layer, carpet layer, or floor cloth to beautify the floor surface, or other decorative material capable of decorating the main floor. The floor main body 200 can be a glued aluminum honeycomb floor, a brazed aluminum honeycomb floor, a composite material, a plywood floor, or a stainless steel floor. A connecting device 300, easily removable and installable, is attached to the underside of the floor main body 200. During disassembly and maintenance, simply unplug the connecting rod 310 from the ball joint 321 on the connecting seat 320 to remove the individual rail transit floor structure in the area requiring repair or demolition, making the operation simple and easy. Preferably, an elastic layer 314 is also included within the accommodating cavity 313, providing the floor with a shock-absorbing function. The rail transit floor structure provided by the present invention utilizes a split design consisting of a connecting rod 310 and a connecting seat 320. The ball joint 321 on the connecting seat 320 corresponds to the receiving cavity 313 provided at the second end 312 of the connecting rod. The opening width of the receiving cavity 313 matches the diameter of the ball joint 321. When the ball joint 321 passes through the opening of the receiving cavity 313, the contact portion is squeezed and deformed. The matching ball joint 321 and the receiving cavity 313 form a quickly pluggable connection structure, making installation and removal quick and easy. Furthermore, the rail transit floor structure of the present invention covers the upper side of a single floor body 200 with a floor decoration layer 100. When the floor is damaged, repairs can be completed by simply disassembling the damaged portion of the rail transit floor structure, saving financial and material resources.

[0039] like Figure 2As shown, in some embodiments provided by the present invention, the rail transit floor structure further includes a height adjustment device 400, which includes an adjustment rod 410. The first end 411 of the adjustment rod is connected to the lower side of the floor body 200, and the second end 412 of the adjustment rod is threadedly connected to the first end 311 of the connecting rod. Preferably, the second end 412 of the adjustment rod is a threaded rod, and the first end 311 of the connecting rod has a threaded hole corresponding to the threaded rod. The height adjustment device 400 in this embodiment can adjust the height of each floor structure during installation, improving the installation effect of the rail transit floor.

[0040] like Figure 3 As shown, a plurality of connection devices 300 are disposed around the floor body 200 , making it easier to achieve balance during the installation of the rail transit floor structure.

[0041] In some specific embodiments, an adhesive layer 323 is provided on the lower side of the base 322 , and the adhesive layer can bond and fix the base 322 to the chassis of the vehicle, which is more convenient than traditional fixing structures such as bolts.

[0042] Another aspect of the present invention provides a rail transit floor, which is formed by splicing the above-mentioned rail transit floor structures. The length of the rail transit floor is a multiple of the length of the floor body 200, and the width of the rail transit floor is a multiple of the width of the floor body 200. According to the current specifications of common rail transit floors, preferably, the length of the floor body 200 is 300-500mm, and the width of the floor body 200 is 300-500mm, which can be adapted to common rail transit floor specifications. When the rail transit floor is spliced ​​by the above-mentioned structure, the length and width of the individual rail transit floor structure are adjusted according to the size of the rail transit floor to adapt to floors of different areas. At the same time, when installing equipment on the vehicle body chassis, there is no need to cut the floor, and only the rail transit floor structure at the corresponding position needs to be removed, which has strong adaptability.

[0043] The following is a specific example to illustrate the operation process of splicing rail transit floors with this rail transit floor structure:

[0044] Example

[0045] Based on the length and width of the rail transit floor, select a rail transit floor structure of corresponding specifications. The specifications must meet the following requirements: the length of the rail transit floor must be a multiple of the length of the floor body 200, and the width of the rail transit floor must be a multiple of the width of the floor body 200. Adjust the threaded depth between the second end 412 of the adjustment rod and the first end 311 of the connecting rod according to the required actual height to ensure that each rail transit floor structure has the same operating height. Then, align the ball joint 321 of the connecting seat 320 with the accommodating cavity 313 of the second end 312 of the connecting rod to connect. Double-sided tape is adhered to the lower side of the base 322 of the connecting seat 320 as an adhesive layer 323. Remove the release paper of the double-sided tape and directly adhere it to the cleaned rail transit vehicle chassis according to the positioning of the entire vehicle floor.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
