[0023] Different excavator models have significantly different boom widths, making them incompatible with a single anti-tipping fixture. This severely impacts transport efficiency, and during transport, the workpiece surface makes line contact with the towing flatbed trailer, resulting in high pressure at the contact points and making it prone to damage.

[0024] To address the aforementioned shortcomings in the existing boom transfer process for excavator structural components, this utility model provides a traction flatbed trailer with a pivot support structure and a quick-change anti-tipping structure, eliminating the problems of low versatility and easy damage to frame tooling, and improving the efficiency and quality of boom transfer.

[0025] like Figure 1 , Figure 5 As shown, a towing flatbed trailer for transporting excavator booms includes a vehicle body 1, a pivot assembly 2, and an anti-tipping device 3. The vehicle body 1 has guardrails 102 extending vertically upwards from both sides in its width direction. The pivot assemblies 2 are respectively arranged on both sides in the length direction of the vehicle body 1, ensuring that the boom placed on the vehicle body 1 is always in surface contact with the pivot assembly 2, increasing the contact area between the boom and the vehicle body 1, and reducing the risk of boom collision. The anti-tipping device 3 is arranged in the middle area of ​​the vehicle body 1. The anti-tipping device 3, in conjunction with the guardrails 102 on both sides, can limit the movement of multiple booms arranged side-by-side, preventing them from tipping over during transport. The anti-tipping device 3 is a movable component, capable of limiting booms of different widths. When the workpiece model changes, only the position of the anti-tipping device 3 needs to be adjusted to meet the transport requirements, while shortening the production cycle of the excavator boom transport tooling.

[0026] As can be seen from the above, the towing flatbed trailer provided by this utility model is designed based on the shape characteristics of the excavator boom. A rotating shaft device is designed at the front and rear of the vehicle body, and the rotating shaft device is connected to the vehicle body through the rotating shaft to ensure that the workpiece and the rotating shaft device are always in surface contact, increasing the bearing area and reducing the risk of workpiece damage. At the same time, an anti-tipping device is designed in the middle of the vehicle body. During transportation, the position of the anti-tipping column can be quickly adjusted according to the width of the workpiece to improve transportation efficiency.

[0027] The following provides a further explanation of the specific structure of the aforementioned anti-tipping device.

[0028] like Figure 1 , Figure 4 , Figure 5 As shown, the anti-tipping device 3 includes two mounting seats 301, a guide shaft 302, a column 305, and a drive component. The two mounting seats 301 are symmetrically fixed on the vehicle body 1 along the width direction of the vehicle body 1. The guide shaft 302 is located between the two mounting seats 301, and both ends of the guide shaft 302 in the length direction are fixed to the corresponding mounting seats. The column 305 stands upright above the vehicle body 1, and the bottom of the column 305 is fitted onto the guide shaft 302, with a clearance fit between the two. The drive component is connected to the column 305 and is used to drive the column 305 to perform linear reciprocating motion along the axial direction of the guide shaft 302. The position of the column 305 can be adjusted to adapt to booms of different widths.

[0029] Further options, such as Figure 1 , Figure 4 , Figure 5 As shown, the driving component includes a screw 303 and a handle 304. The screw 303 is rotatably supported on two mounting bases 301. The guide shaft 302 is located directly below the screw 303. The screw 303 passes through the column 305, and a helical pair is formed between them. The circumferentially rotating screw 303 drives the column 305 to move linearly. The handle 304 is connected to the screw 303, and rotating the handle 304 drives the screw 303 to rotate.

[0030] Further options, such as Figure 4 As shown, both ends of the guide shaft 302 and the screw 303 in the length direction are set as stepped mounting surfaces, which are inserted into the mounting seats 301 on both sides. The guide shaft 302 and the mounting seat 301 are in a shaft-hole transition fit, and the screw 303 and the mounting seat 301 are in a shaft-hole clearance fit.

[0031] In a further embodiment, the central area of ​​the vehicle body 1 is provided with anti-tipping devices 3 arranged in M ​​rows and N columns, where M and N are both integers ≥1; a boom can be placed between the guardrail 102 and a column of posts 305 close to the guardrail, as well as between two adjacent columns of posts 305.

[0032] Preferred solutions, such as Figure 1, Figure 5 As shown in the attached diagram, a preferred embodiment is provided, wherein the central area of ​​the vehicle body 1 is provided with four anti-tipping devices 3 arranged in two rows and two columns, which can simultaneously accommodate three booms arranged side by side.

[0033] Further options, such as Figure 1 As shown, the mounting base 301 has a convex shape. Each of the two side platforms of the mounting base 301 has a through hole extending vertically downward. The vehicle body 1 has a threaded hole arranged coaxially with the through hole. The mounting base 301 is fixed to the vehicle body 1 by bolts.

[0034] The following provides a further explanation of the specific structure of the aforementioned rotating shaft device.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the rotating shaft device 2 includes a rotating shaft 201 and a rotating block. The rotating shaft 201 is located between a pair of opposing mounting blocks 101 on the side of the vehicle body 1, and both ends of the rotating shaft 201 in the length direction are respectively inserted into the corresponding mounting blocks 101, with the two having a shaft-hole transition fit. The outer contour of the rotating block is a square structure, and the rotating block is fitted on the rotating shaft 201, with the two having an insertion clearance fit, so that the rotating block can rotate freely on the rotating shaft 201, so that the bottom surface of the boom can be in contact with any side of the rotating block.

[0036] Further options, such as Figure 3 As shown, the rotating block consists of a reinforcing tube 202, a square steel tube 203, and a protective rubber 204 from the inside out. The rotating shaft 201 and the reinforcing tube 202 are fitted with an insertion clearance fit, and the reinforcing tube 202 and the square steel tube 203 are also fitted with an insertion clearance fit. The reinforcing tube 202 enhances the strength of the rotating shaft device and improves its load-bearing capacity. The square steel tube 203 added outside the reinforcing tube 202 increases the load-bearing area. The protective rubber 204 is fixed to the square steel tube 203 with screws, further increasing the load-bearing contact area.

[0037] Further options, such as Figure 1 , Figure 2 As shown, three symmetrically arranged mounting blocks 101 are fixed on each of the two sides of the vehicle body 1 in the width direction. One mounting block 101 is located in the middle area of ​​the side of the vehicle body 1, and the other two mounting blocks 101 are located at the two ends of the side of the vehicle body 1, respectively. A rotating shaft device 2 is provided between the middle mounting block 101 and the mounting block 101 at one end, and a rotating shaft device 2 is provided between the middle mounting block 101 and the mounting block 101 at the other end.

[0038] In the preferred embodiment, guardrail 102 is a ∩-shaped structure composed of one horizontal bar and two vertical bars joined together.

[0039] The assembly sequence of this utility model is as follows: the protective rubber 204 is fixed to the square steel tube 203 with screws, the reinforcing tube 202 is inserted into the square steel tube 203, and the rotating shaft 201 is simultaneously inserted into the reinforcing tube 202 and the mounting block 101 to complete the installation of the rotating shaft device 2; the screw 303 is screwed into the column 305, the guide shaft 302 is inserted into the column 305, the screw 303 and the guide shaft 302 are simultaneously inserted into the mounting base 301 on both sides, the screw 303 is inserted into the handle 304, and the mounting base 301 is fixed to the vehicle body 1 with bolts to complete the installation of the anti-tipping device 3.

[0040] In the operation of this utility model, the handle 304 is rotated according to the model of the workpiece to be transferred, causing the column 305 to slide to the corresponding position and be fixed in that position by the self-locking effect of the screw. After the workpiece is placed, it contacts the rotating shaft device 2. Under pressure, the rotating shaft device 2 rotates around the rotating shaft 201, causing the protective rubber 204 to adhere to the surface of the workpiece. The whole process is simple and efficient, greatly shortening the changeover time of the transfer tooling and improving the transfer efficiency.
