It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0025] In the description of the present invention, it is necessary to understand that the terms "front", "upper", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the protection content of the present invention.

[0026] like Figure 1-Figure 5 As shown, a cab floor inspection opening cover structure comprises a floor cover 1 installed on the cab floor inspection opening, a small inspection opening is opened on the floor cover 1, and a small inspection opening cover 2, a transition plate and a molded rubber pad are installed on the floor cover 1;

[0027] The small inspection port cover plate 2 is installed on the bottom plate cover plate 1 and corresponds to the small inspection port. Multiple transition plates are installed on the bottom plate cover plate 1. The molded rubber pad includes a molded rubber pad 6 installed above the bottom plate cover plate 1 and the small inspection port cover plate 2, a molded rubber pad 2 7 and a molded rubber pad 3 8 respectively connected to the molded rubber pad 1 6. The molded rubber pad 1 6 is provided with mounting holes corresponding to the transition plates for installing foot pedals on the transition plates.

[0028] In some embodiments of the present disclosure, Figure 1 , Figure 5 As shown, the molded rubber pad 16 is embedded with a strong magnet 11, and the molded rubber pad 16 is fixed to the bottom plate of the cab by magnetic adsorption. Specifically, the molded rubber pad 16 is embedded with six (three on each side) strong magnets 11 inside the rubber pad at the door sills on both sides, so that the molded rubber pad 16 can be easily adsorbed and fixed to the bottom plate of the cab by magnetic force after assembly. In order to improve the stability of magnetic adsorption, the strong magnets 11 on both sides can be arranged symmetrically.

[0029] In some embodiments of the present disclosure, Figure 1As shown, each molded rubber pad is provided with a concave-convex structure, and the molded rubber pad 2 7 and the molded rubber pad 3 8 are respectively connected to the molded rubber pad 1 6 through the concave-convex structure. The three molded rubber pads are buckled and fixed by their own concave-convex structures, and no additional fixing structure is required, so the structure is simpler and the disassembly and assembly are more convenient.

[0030] In some embodiments of the present disclosure, Figure 1 , Figure 2 As shown, the upper surface of each molded rubber pad is provided with a plurality of laterally distributed protruding textures for increasing friction and facilitating cleaning.

When inspecting the lower parts of the bottom plate, the small inspection port cover 2 can be opened, and the connector of the foot pedal can be plugged and unplugged through the small inspection port on the bottom plate cover 1. This avoids the inconvenience of one person having to lift the bottom plate cover 1 and the other person plugging and unplugging the foot pedal connector from the gap at the front end of the bottom plate cover 1 during the inspection process, thereby avoiding the safety hazard of being hit or squeezed by the bottom plate cover 1.

[0033] In some embodiments of the present disclosure, Figure 1 , Figure 2 As shown, the inclined surface of the mounting hole on the molded rubber pad 6 half covers the transition plate. When the molded rubber pad 6, the frontmost of the three molded rubber pads, is installed, the two mounting holes on it are covered over the foot pedal, and the inclined surface in the opening half covers the transition plate for installing the foot pedal, and finally covers the bottom plate cover 1, so that the installation and removal of the molded rubber pad 6 are simple and convenient, and there is no necessary connection with the installation and removal of the foot pedal, that is, the foot pedal does not need to be removed before the molded rubber pad 6 is removed, and the molded rubber pad 6 does not need to be installed before the foot pedal is installed, thereby reducing the removal frequency of the foot pedal, simplifying the assembly and maintenance process, and extending the service life.

[0034] In some embodiments of the present disclosure, Figure 1 , Figure 4 As shown, the transition plate includes a transition plate 1 3 and a transition plate 2 4 installed on the bottom plate cover 1, and a foot pedal 10 is correspondingly installed on the transition plate 1, and a foot pedal 2 9 is correspondingly installed on the transition plate 2 4. Through the set transition plates, various models of foot pedals or other models of similar foot pedals can be installed, which is more convenient to use.

[0035] According to a second aspect of the present disclosure, there is provided a cab, on which the cab floor inspection port cover structure is installed.

[0036] According to a third aspect of the present disclosure, there is provided an engineering machine on which the driving cab is installed.

[0037] The utility model provides a cab floor inspection port cover structure, and various types of foot pedals can be installed on the transition plate; the small inspection port cover covers the top of the floor cover and is fixed by bolts, and the small inspection port cover can be opened when inspecting the lower parts of the floor, and the connector of the foot pedal can be plugged in and out through the small inspection port, avoiding the inconvenience of the traditional inspection process requiring one person to lift the floor cover and the other person to plug in and out the foot pedal connector from the gap at the front end of the floor cover, and avoiding the risk of being hit or squeezed by the floor cover.

[0038] The cab floor inspection opening cover structure of the utility model simplifies the assembly and disassembly processes of the floor cover, molded rubber pads, foot pedals and other components during assembly and maintenance, reduces workload, reduces safety risks during operation, and extends the service life of various components.

[0039] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
