Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing, and in particular to a chassis transport skid. Background Technology

[0002] Currently, the truck industry offers a wide variety of chassis types. As customers increasingly demand rust-resistant chassis, many domestic OEMs have begun building chassis topcoat conveyor lines. These lines must meet both conveying requirements and chassis painting requirements; therefore, they must be versatile and practical.

[0003] Currently, most chassis paint conveyor lines transport chassis via conveyor skids. However, due to the large number of vehicle models and chassis types, these skids are insufficient to accommodate all chassis. Particularly for long-wheelbase vehicles and pre-installed chassis of special models, the existing chassis paint conveyor lines' skids cannot support these vehicles, making it difficult for them to pass through the existing lines. Therefore, the current chassis paint conveyor lines have limited versatility. Summary of the Invention

[0031] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0032] Please see Figure 1 This invention provides a chassis transport skid 10. The chassis transport skid 10 is used to transport a vehicle base 2. Typically, the vehicle base is elongated, and therefore the chassis transport skid is also elongated. Furthermore, the vehicle chassis is divided into a front-to-back direction according to the direction of vehicle travel. Specifically, the vehicle chassis 2 may include structures such as a front axle 21, longitudinal beams 22, a middle and rear axle 23, and a rear axle 24. Correspondingly, the front-to-back direction of the chassis transport skid corresponds to the front-to-back direction of the vehicle chassis.

[0033] Please see Figure 2 Specifically, in this embodiment, the chassis transport skid 10 includes a base 11, a moving trolley 12, a front support 13, and a movable support 14.

[0034] The base 11 is stably placed on the ground. The base 11 has a frame structure. The base 11 includes vertical beams 111 extending along its direction. To enhance the strength of the base 11, there are three vertical beams 111, spaced apart from each other. Furthermore, a horizontal beam 112 is provided perpendicular to the three vertical beams 111, connecting the three vertical beams 111 to further enhance the strength of the base 11. Specifically, the base 11 is a steel structure. The vertical beams 111 and the horizontal beams 112 can be made of channel steel or square steel, etc.

[0035] Furthermore, the base 11 of the chassis transport skid 10 in this embodiment also includes an extension (not shown). The extension is located at the other end of the base 11. Specifically, the length of the extension can be 200mm. The extension on the base 11 increases the overall length of the base 11, thereby ensuring the range of motion of the trolley 12 in the chassis transport skid 10 and enhancing the adjustment range of the movable support 14.

[0036] Furthermore, the extension of the base 11 can be achieved by increasing the overall length of the base 11, that is, the extension is integrally formed on the base 11.

[0037] The front support 13 supports the front axle 21 of the chassis. The front support 13 is fixedly mounted on one end of the base 11. Since the front axle 21 is located at the front end of the chassis, the front support 13 is also fixedly mounted on the front end of the base 11. The front axle 21 can serve as the starting point of the vehicle chassis; regardless of the vehicle model, the front support 13 can support the front axle 21 of the chassis 2. Therefore, to enhance the stability of the front support 13 structure, it is fixedly mounted on the front end of the base 11. The front support 13 can be fixed to the base 11 by welding or screwing.

[0038] The trolley 12 is slidably mounted on the base 11. The base 11 has slide rails 121 on both sides, and the trolley 12 has rollers 122 on both sides, which slide along the slide rails 121. Specifically, the slide rails 121 are located above the vertical beams 111 on both sides of the base 11, and have guide grooves. The rollers 122 of the trolley 12 are housed in the guide grooves and roll along them, thereby driving the entire trolley 12 to move along the slide rails 121. The slide rails 121 can be angle steel or channel steel.

[0039] There can be multiple motion carts 12, and the multiple motion carts 12 are distributed along the axial direction of the base 11.

[0040] The vertical beam 111 of the base 11 has multiple positioning holes along the axial direction. The moving trolley 12 is provided with positioning pins 123, which are inserted into the positioning holes to position the moving trolley 12. When the moving trolley 12 moves to the predetermined position, the positioning pins 123 position the moving trolley 12 to prevent displacement.

[0041] The movable support 14 is mounted on the trolley 12. The trolley 12 slides along the base 11, causing the movable support 14 to move along the base 11. The movable support 14 is rotatably mounted on the trolley 12. Please refer to [link / reference]. Figure 3 The movable support 14 is erected and perpendicular to the base 11 to support the chassis longitudinal beam 22. The movable support 14 rotates and falls onto the trolley 12, and the height of the movable support 14 after falling is lower than the height of the front support 13.

[0042] In this embodiment, the chassis transport skid 10 allows for the erection of a movable support 14 to support the chassis longitudinal beam 22 when the front support 13 cannot support the front axle 21 structure of a chassis 2 with a special wheelbase. This supports the vehicle chassis, enabling the chassis to be transported via the chassis transport skid 10. Furthermore, the movable support 14 is rotatably mounted on the trolley 12. By adjusting the position of the trolley 12, the support positions of the movable support 14 and the chassis longitudinal beam 22 can be adjusted, further increasing the passability of the chassis transport skid 10. When the movable support 14 is not needed, it can be rotated relative to the trolley 12 to fold down, with the folded height lower than the height of the front support 13. Therefore, for chassis of ordinary vehicles, the front axle 21 structure is supported by the front support 13, allowing the chassis to be transported via the chassis transport skid 10.

[0043] Therefore, the aforementioned chassis transport skid 10 can be adapted to the passability of more vehicle models' chassis. Even if new chassis with different wheelbases are added later, the aforementioned chassis transport skid 10 can meet their passability requirements.

[0044] For details in this embodiment, please also refer to Figure 4 The movable support 14 includes a support column 141 and a support base 142. The support base 142 is fixedly mounted on the moving trolley 12. The support column 141 and the support base 142 are rotatably connected. Specifically, there are two support bases 142 and two support columns 141, with each support column 141 corresponding to one support base 142, and a connecting rod 143 between the two support columns 141. That is, the two support columns 141 and the connecting rod 143 are arranged in an "H" shape. The "H"-shaped movable support 14 has a stable structure and high strength, and can support a heavy vehicle chassis. The support column 141 and the connecting rod 143 can be made of square steel, and the support column 141 and the connecting rod 143 are welded together.

[0045] Specifically, in this embodiment, the movable support 14 further includes a pin 144. The support column 141 and the support base 142 are rotatably connected via the pin 144. Please also refer to... Figure 3 The support column 141 and / or support base 142 are respectively provided with shaft holes 145, and the pin 144 is rotatably disposed in the shaft hole 145.

[0046] Furthermore, the support base 142 has a rectangular frame structure. Support arms 146 protrude from opposite sides of the support base 142. The two ends of the pin 144 are respectively fixed to the two support arms 146. Shaft holes 145 are formed on opposite sides of the support column 141 and the support arms 146. The shaft holes 145 are elongated holes extending axially along the support column 141. The pin 144 can move within the shaft hole 145 to drive the pin 144 to its position within the shaft hole 145. Different positions of the pin 144 within the shaft hole 145, i.e., different connection positions between the support column 141 and the support base 142, allow adjustment of the height of the movable support 14 to accommodate the height of the longitudinal beam 22 in vehicles with different wheelbases.

[0047] Furthermore, the pin 144 can move relative to the shaft hole 145, which facilitates the easy entry and exit of the support column 141 into the support base 142.

[0048] In other embodiments, the shaft hole 145 is formed on the support arm 146 of the support base 142, and the pin 144 is fixedly disposed on one end of the support column 141 near the support base 142. Alternatively, both the support arm 146 and the support column 141 are provided with shaft holes 145, one end of the pin passes through the shaft hole 145 on the support arm and the support column 141, and then the support arm and the support column 141 are fixedly connected by fasteners.

[0049] A slot is provided on the outer wall of the support column 141 near the support base 142. When the support column 141 is erected on the support base 142, the support column 141 rotates. When the slot and the support arm can engage and connect, the support column 141 rotates into position. Therefore, the support arm can be accommodated in the slot, and the support column 141 can remain stably erected on the support base 142.

[0050] The movable support 14 also includes at least two fastening bolts 147, which are fixedly disposed on two opposite side walls of the support base 142, with the end faces of the fastening bolts 147 abutting against the side surfaces of the support column 141. Specifically, the fastening bolts 147 are disposed on the other opposite side walls of the support base 142 relative to the support arm. When the support column 141 rotates to its position relative to the support base 142, it is necessary to limit the movement between the support column 141 and the support base 142. The fastening bolts 147 can then fasten the support column 141 from opposite sides to position it.

[0051] The movable support 14 is also provided with a support platform 148, which is located at the end of the support column 141 away from the support base 142. The support platform 148 is used to abut against the chassis longitudinal beam 22. Furthermore, a rib plate 149 is provided between the support platform 148 and the support column 141. The rib plate 149 can distribute the pressure on the support platform 148 to improve the compressive strength of the movable support 14.

[0052] The chassis transport skid 10 of this embodiment also includes a sliding support for supporting the front axle 21 of the chassis. The sliding support is mounted on a trolley 12, which drives the sliding support to move. There can be multiple trolleys 12, which can support both the movable support 14 and the sliding support. The sliding support mounted on the trolley 12 is located between the front support 13 and the movable support 14. For chassis models with ultra-short wheelbases, such as 8x4, the wheelbase is 1950mm, 2200mm, or 1350mm. Because the chassis parts of ultra-short wheelbase models are assembled compactly, the longitudinal beam 22 has no load-bearing points, and the movable support 14 cannot support the longitudinal beam 22. At the same time, the vehicle chassis can include multiple front axles, with the one at the very front of the chassis being the first front axle, and the one behind the first front axle being the second front axle. Because the length of the ultra-short wheelbase chassis 2 is relatively short, if the front support 13 supports the first front axle, the center of gravity of the chassis is located in the front half of the chassis transport skid 10. Therefore, during the process of transporting the ultra-short wheelbase chassis by the chassis transport skid 10, the chassis is prone to imbalance and tipping over, affecting the passability of the ultra-short wheelbase vehicle chassis.

[0053] Therefore, for chassis with an ultra-short wheelbase, a sliding support is required. This sliding support moves to the position of the second front axle and supports it. Consequently, the center of gravity of the ultra-short wheelbase chassis shifts behind the transport skid on the base 11, ensuring its center of gravity is close to the centerline of the transport skid and guaranteeing stable transport and adequate ground clearance. Furthermore, for 8x4 chassis with a wheelbase less than 4350mm, the second front axle must be placed on the sliding support.

[0054] The chassis transport skid 10 of this embodiment also includes a rear support 15 for supporting the rear axle of the base 11. The rear support 15 is located at the other end of the base 11 relative to the front support 13. The rear support 15 supports the rear end of the base 11 and can be used to support the middle rear axle 23 and the rear axle 24 of the chassis. Furthermore, the rear support 15 can be slidably mounted on the base 11 via a trolley 12. The support position of the rear support 15 relative to the chassis 2 can be adjusted by the trolley 12.

[0055] The base 11 conveyor skid 10 of this embodiment has the following advantages over the conventional base 11 conveyor skid:

[0056] Firstly, for chassis with an extra-long wheelbase, such as a 6*2 wheelbase (6000mm, 1350mm), the longitudinal beams 22 of the chassis can be supported by the movable support 14 to meet the requirements for passability.

[0057] Secondly, for long-wheelbase vehicle chassis, such as vehicles with a wheelbase of 8*4 (wheelbase of 1950mm, 4800mm, 1350mm), the extended part of the base 11 can meet the passability requirements of long-wheelbase vehicle chassis, and the longitudinal beam 22 can also be supported by the movable support 14 to meet the passability requirements.

[0058] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
