Description

Technical Field

[0001] The utility model relates to the technical field of tractors, in particular to a working platform device for a tractor. Background Art

[0002] As a common device on tractors, the work platform is not only convenient for drivers and maintenance personnel to use as a standing platform when they need to maintain and repair the rear part of the engine, but also convenient for users to stand when getting on the vehicle to connect the brake and electrical devices of the trailer and tractor.

[0003] Existing tractor platform installations are typically rigidly connected to the vehicle frame's longitudinal beams via fixed brackets and bolts, and mounted above the beam. However, due to the inevitable torsional deformation of the longitudinal beams during vehicle operation, these rigidly connected platforms are susceptible to loosening and falling bolts, which can affect normal operation. Furthermore, this rigid connection prevents the platform from being able to adjust its position. This means that when components underneath the platform interfere with the platform, the platform cannot be adjusted to avoid interference. Summary of the Invention

[0021] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the embodiments described are only a portion of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0022] like Figure 1-6 As shown, in some illustrative embodiments, a working platform device for a tractor is provided, comprising: a working platform cover plate 1, a fixing bracket 2 and a long strip-shaped shock-absorbing pad 3.

[0023] The work platform cover 1 is designed by stamping aluminum alloy, which has the characteristics of lightness and high strength. The surface is anti-slip treated to ensure safety when standing. The fixing bracket 2 is used to fix the work platform cover 1 to the frame. It is made of high-strength steel or aluminum alloy to ensure sufficient connection strength and supporting force. There are two long strip shock-absorbing pads 3 to balance and disperse the torsion and vibration from the vehicle during driving, and the two long strip shock-absorbing pads 3 are respectively arranged at the bottom of the two ends of the work platform cover 1. After the installation is completed, the long strip shock-absorbing pads 3 are in contact with the upper surface of the upper wing surface 11 of the frame longitudinal beam. Specifically, the long strip shock-absorbing pads 3 are fixed between the upper wing surface 11 of the frame longitudinal beam and the work platform cover 1 by 3M adhesive strips. It mainly plays the role of absorbing torsion and vibration, reducing the impact of these dynamic forces on the installation components, thereby greatly reducing the risk of bolt loosening during vehicle driving.

[0024] The work platform cover 1 has two groups of oblong holes at positions corresponding to the two frame longitudinal beams 10, and each group of oblong holes has two oblong holes 101. Therefore, a total of four oblong holes 101 are provided on the work platform cover 1, and the length of the oblong hole 101 is 65 mm and the width is 11 mm. This size design can provide sufficient adjustment space while maintaining the stability of the structure. The fixed bracket 2 is fixed to the oblong hole 101 through the installation assembly. The design of the oblong hole 101 allows the fixed bracket 2 to move laterally in the hole, thereby achieving the spacing adjustment of the fixed bracket 2, and then the installation position of the work platform cover 1 can be adjusted forward and backward according to actual needs to avoid possible interference problems, such as interference with the trailer connection device or other components. The above structural design not only improves the versatility of the work platform device, but also the introduction of the adjustment mechanism makes the installation process more flexible, and there is no need to design a separate work platform for each vehicle model.

[0025] The fixing bracket 2 includes: a bracket plate body 201 and a mounting assembly arranged on the bracket plate body 201 , wherein the mounting assembly includes: a hexagonal flange bolt 4 , a washer 5 and a welding nut 6 .

[0026] The inner side of the bracket plate body 201 is bent upward to form a clamping bracket 204 perpendicular to the bracket plate body 201. The outer side of the bracket plate body 201 is provided with a clamping support plate 202 spaced a certain distance from the lower surface of the work platform cover plate 1. The upper surface of the clamping support plate 202 is provided with a TPE rubber pad 203. Specifically, the outer side of the bracket plate body 201 is bent downward and extended outward to form a clamping support plate 202 parallel to the bracket plate body 201. The clamping support plate 202 is spaced a certain distance from the lower surface of the work platform cover plate 1 to form a clamping groove 205 for accommodating the upper wing surface 11 of the frame longitudinal beam.

[0027] The working platform device of the present application is clamped and mounted on the upper wing surface 11 of the frame longitudinal beam through the fixing bracket 2. That is, after the installation is completed, the upper wing surface 11 of the frame longitudinal beam is clamped in the clamping groove 205 between the working platform cover plate 1 and the clamping support plate 202. At this time, the long strip shock-absorbing pad 3 is fixed between the upper surface of the upper wing surface 11 of the frame longitudinal beam and the working platform cover plate 1. At the same time, the TPE rubber pad 203 is fitted with the lower surface of the upper wing surface 11 of the frame longitudinal beam, that is, the TPE rubber pad 203 is fixed between the lower surface of the upper wing surface 11 of the frame longitudinal beam and the clamping support plate 202.

[0028] Mounting screw holes are provided on the support plate body 201, and weld nuts 6 are welded to the lower surface of the support plate body 201. The stem of the hexagonal flange bolt 4 passes through the washer 5, the oblong hole 101, and the mounting screw hole on the support plate body 201 from the top of the work platform cover 1, and is then tightened through the weld nut 6. The hexagonal flange bolt 4 and the weld nut 6 are used in conjunction to secure the fixed bracket 2 to the oblong hole 101 provided in the work platform cover. After installation, the head of the hexagonal flange bolt 4 presses the washer 5 against the upper surface of the work platform cover 1, and the upper surface of the support plate body 201 is in contact with the lower surface of the work platform cover 1. The TPE rubber pad 203 and the washer 5 reduce friction between the fixed bracket 2 and the frame longitudinal rail 10, further providing shock absorption and energy absorption.

[0029] In this application, since the work platform cover 1 is not rigidly connected to the longitudinal beam through brackets and bolts, but is clamped and mounted on the upper wing surface 11 of the frame longitudinal beam through the fixing bracket 2 via the installation assembly, the structural design can realize the adjustment of the installation position of the work platform device to avoid possible interference, thereby improving the versatility of the work platform. At the same time, combined with the use of long strip shock-absorbing pads 3, washers 5 and TPE rubber pads 203, it can effectively absorb the torsional deformation of the frame during driving and reduce the risk of the installation bolts loosening and falling off.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
