[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Example 1

[0023] like Figure 1 and 2 As shown, the fixing structure for installing the vehicle ladder and the front connection of the floor in this embodiment includes a first connecting member 1, a second connecting member 2, a vehicle ladder 3, a first front connection of the floor 4, a mounting seat 5, a third connecting member 6 and a second front connection of the floor 7. The vehicle ladder 3 is horizontally arranged, one end of the first connecting member 1 is connected and fixed to one end of the vehicle ladder 3, and the other end extends upward and is connected and fixed to the first front connection of the floor 4, one end of the second connecting member 2 is connected and fixed to the other end of the vehicle ladder 3, and the other end extends upward and is connected and fixed to the mounting seat 5, and the mounting seat 5 is installed at the lower end of the tractor column, one end of the third connecting member 6 is connected and fixed to the mounting seat 5, and the other end extends upward and is connected and fixed to the second front connection of the floor 7.

[0024] The fixing structure for installing the step ladder and the front connection of the floor in this embodiment realizes the overall assembly of the tractor floor and the step ladder 3 by integrally connecting the step ladder 3 with the first front connection of the floor 4 and the second front connection of the floor 7, and the second connecting member 2 is installed on the lower end of the tractor column (specifically, the support connected between the lower end of the column and the side end of the chassis bracket of the tractor, indicated by a in the figure). Specifically, a set of fixing structures is respectively provided on the columns connected on the left and right sides of the tractor bracket, with a total of four floor connections, and the floor is assembled on the four floor connections. The entire structural design is simple and reasonable. Under the premise of ensuring the strength of the assembly structure, the step ladder 3 and the front connection of the floor are integrally connected and assembled through an integrated bracket, which reduces the number of brackets, reduces the overall weight and consumables cost, and optimizes the spatial layout.

[0025] In this embodiment, the first connecting member 1 is formed by bending a pipe. Specifically, one end of the first connecting member 1 extends vertically downward and is welded to one end of the step ladder 3. The other end of the first connecting member 1 is bent horizontally or obliquely to extend toward the upper part of one side thereof, and the other end is welded to the side end of the first floor front connection 4. The bending part of the first connecting member 1 is in a circular arc transition.

[0026] In this embodiment, the second connecting member 2 is formed by bending a pipe. Specifically, one end of the second connecting member 2 extends vertically downward and is welded to the other end of the step ladder 3. The other end of the second connecting member 2 is bent horizontally or obliquely to the upper part of one side thereof, and the other end is welded to the mounting seat 5. The first connecting member 1 and the second connecting member 2 are arranged in parallel. The bending part of the second connecting member 2 is in a circular arc transition.

[0027] In this embodiment, the hydraulic pipeline is arranged below the step ladder 3, and the layout is more compact.

[0028] In this embodiment, the mounting seat 5 is a sheet metal part with an L-shaped cross section, the other end of the second connecting member 2 is welded to one side of the mounting seat 5, the other side of the mounting seat 5 is attached to the side of the lower end of the tractor column, and is connected and fixed to the tractor column by high-strength bolts passing through it. Such a design facilitates the assembly and fixation of the second connecting member 2 thereto, and also facilitates the connection and assembly of the mounting seat 5 with the lower end of the column.

[0029] In this embodiment, the third connecting member 6 is formed by bending a pipe, one end of the third connecting member 6 extends vertically downward and is welded to one side of the mounting seat 5, the other end of the third connecting member 6 is horizontally bent toward the upper part of one side and is welded to the second floor front connection 7, and the bending part of the third connecting member 6 is a circular arc angle transition.

[0030] As a preferred embodiment, the upper end surfaces of the first floor front connection 4 and the second floor front connection 7 are both designed to be planes and are located at the same horizontal height.

[0031] In the above embodiment, the upper end surfaces of the first floor front connection 4 and the second floor front connection 7 are in the same horizontal plane, so that the floor can be assembled relatively flat at the upper ends of the two floors.

[0032] In this embodiment, the upper ends of the first floor front connection 4 and the second floor front connection 7 are respectively provided with shock-absorbing pads (indicated by b in the figure), and are respectively connected to the floor through bolts passing through the shock-absorbing pads. Specifically, the bolts pass through the bolt holes on the floor, the shock-absorbing pads, and the through holes on the first floor front connection 4 or the second floor front connection 7 from top to bottom, and are connected with nuts for locking.

[0033] As a preferred embodiment, connecting plates 31 are respectively welded to the lower parts of the two ends of the above-mentioned ladder 3, and the connecting plates 31 protrude outside the two ends of the above-mentioned ladder 3, and one end of the above-mentioned first connecting member 1 and one end of the above-mentioned second connecting member 2 are respectively welded to the protruding parts of the connecting plates 31 at the two ends of the above-mentioned ladder 3.

[0034] In the above embodiment, the edge of the ladder 3 is set as an edge with a rounded corner bent downward, which is not convenient for welding the first connecting member 1 and the second connecting member 2. Therefore, a connecting plate 31 is welded at the lower part of each end of the ladder 3, and the connecting plate 31 protrudes from the corresponding end of the ladder 3 and is then welded to the first connecting member 1 or the second connecting member 2, so that the welding area is large and the welding is relatively firm.

[0035] In this embodiment, the above-mentioned step ladder 3 is provided with hollow areas 32 from the middle to both ends thereof, and the above-mentioned hollow areas 32 are provided with reinforcing ribs 33, and the edges of the above-mentioned hollow areas 32 and the upper parts of the above-mentioned reinforcing ribs 33 are provided with anti-slip convex points. The design of the hollow areas 32 can reduce the weight of the step ladder 3 and reduce the cost of consumables. At the same time, the design of the reinforcing ribs 33 makes up for the structural strength problem of the hollow areas 32. In addition, the edges of the upper edges of the hollow areas 32 and the upper parts of the reinforcing ribs 33 are provided with serrated protective convex points, which are not easy to slip when the driver steps on them, thereby improving the safety of getting on the vehicle.
