Description

Technical Field

[0001] The present invention belongs to the technical field of engineering vehicles, and in particular relates to a traction frame connecting an engineering machine and a trailer. Background Art

[0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

[0003] Timber transportation is a crucial link in forestry operations. In traditional forestry operations, after felling trees in the forest by forest machines, it is often impossible to directly transport these timbers effectively. This is mainly because the felled timber needs to go through a series of collection and sorting work before it can be transported. However, the vehicles that transport these timbers often have high requirements for road conditions, which makes it difficult for transport vehicles to pass in some mountainous areas or areas with poor road conditions, where the roads are narrow, rugged, or even no roads at all. In this case, timber transportation often needs to rely on other modes of transportation, such as helicopter lifting or water transportation, but this will undoubtedly greatly increase the cost and complexity of transportation.

DETAILED DESCRIPTION

[0026] like Figures 1 to 6 As shown, this embodiment provides a traction frame connecting engineering machinery and a trailer, a motor mounting seat 2 is arranged at the end of the engineering vehicle in the driving direction, and the traction frame includes a main beam 4, a fixing seat 5 and brackets 6 symmetrically arranged on both sides of the main beam 4.

[0027] like Figure 1 As shown, a lower vertical plate 8 welded to the main beam is provided at one end of the bracket, the bracket 6 is arranged at an acute angle with the main beam 4, and a fixing seat 5 is arranged at the other end; the main beam 4 is fixed to the chassis platform 1 through a connecting seat 7, and the connecting seat 7 is arranged on the side of the chassis platform 1 opposite to the driving direction of the engineering vehicle.

[0028] Specifically, Figure 2 and Figure 3 As shown, the connecting seat 7 includes two mounting ear plates 10 and a cylinder 9, the mounting ear plates 10 are welded on the chassis platform 1, and the cylinder 9 is arranged between the two mounting ear plates 10 and assembled by connecting the pin shaft 11, so that the traction frame can be stably connected to the chassis platform 1 through the connecting seat 7. The connection pin shaft 11 realizes the connection between the traction frame and the connecting seat 7, and the disassembly is convenient, thereby ensuring the flexibility and stability of the overall structure.

[0029] like Figure 5 and Figure 6 As shown, the bracket 6 is composed of two connecting frames connected by bolts through a square flange 17 using hexagonal bolts. The connecting frame is close to the main beam 4 as a first connecting frame 16, and the connecting frame connected to the fixing seat 5 is a second connecting frame 18; the fixing seat 5 is composed of a connecting vertical plate 19 and two limiting plates 3 connected by bolts, and the limiting plates 3 are vertically arranged on the connecting vertical plate 19 and parallel to the straight edges on the upper and lower sides of the motor mounting seat 2. The distance between the limiting plates 3 is consistent with the thickness of the motor mounting seat 2.

[0030] Specifically, the limit plate 3 is welded to the upper and lower sides of the motor mounting base, the connecting vertical plate 19 is welded to the second connecting frame 18, and the limit plate 3 is connected to the connecting vertical plate 19 by bolts to form two additional connecting support points on the motor mounting base 2. Combined with the connection point between the connecting base 7 and the base frame platform 1, a rigid connection of three points is finally formed, making the traction frame more solid and able to bear greater traction force.

[0031] like Figure 3 The main beam 4 shown is a box structure formed by two sets of main beam cover plates 12 and main beam side vertical plates 13 which are vertically combined with each other.

[0032] Specifically, two sets of main beam cap plates 12 and main beam side plates 13 are fixed by welding to form a strong and stable box structure, which not only has a high load-bearing capacity, but also has good stability and bending resistance, and can effectively withstand various external forces and loads.

[0033] One end of the main beam cover plate 12 is a semicircular arc edge, and a pin shaft hole for connecting the trailer is set at the center of the semicircle. The other end is a right-angled side, which is fixedly connected to the outer side of the cylinder 9 of the connecting seat 7 in the axial direction.

[0034] Both ends of the main beam side vertical plate 13 are concave arc structures, which are fixedly connected to the outer circumferential direction of the cylinder 9, thereby realizing the swing between the traction frame and the base frame platform 1 through the cylinder 9.

[0035] A patch plate 14 is also provided on the semicircular end of the main beam cover plate 12. The patch plate 14 is welded to the main beam cover plate 12 at the upper and lower parts of the box structure of the main beam 4. The rigidity of the main beam is strengthened by the patch plate 14, so that the main beam can withstand greater traction after being connected to the trailer.

[0036] like Figure 4 As shown, reinforcing ribs 15 are welded between the main beam cover plate 12 and the lower vertical plate 8 at the bottom of the main beam 4. The reinforcing ribs 15 are provided with 4 groups of welding points respectively located at the welding positions of the bracket 6 and the main beam 4, ensuring the stability and bearing capacity of the traction frame structure, and also providing additional strength and rigidity for the entire traction frame. At the same time, the reinforcing ribs 15 can effectively disperse and transfer the load, thereby improving the reliability and durability of the overall structure.

[0037] The working principle of the utility model is as follows: First, the connecting seat 7 is firmly fixed on the chassis platform 1 by welding to ensure its stability and durability. Then, the limit plate 3 is welded to the upper and lower sides of the motor mounting seat, and the connecting vertical plate 19 is welded to the second connecting frame 18. The limit plate 3 is connected to the connecting vertical plate 19 by bolts to ensure the close combination between the two. Subsequently, the main part of the traction frame is combined together by bolt connection to ensure the close fit between the various components. In this way, two additional connection support points can be formed on the motor mounting seat 2. Combined with the connection point between the connecting seat 7 and the chassis platform 1, a rigid connection of three points is finally formed, making the traction frame more solid and able to bear greater traction, thereby forming a solid overall structure. Finally, the trailer is connected to the pin hole on the traction frame by means of a pin shaft, which can achieve fast and convenient connection and separation, greatly improving the efficiency and convenience of wood transportation.

[0038] Although the above describes the specific implementation methods of the present disclosure in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present disclosure. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present disclosure, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present disclosure.
