Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a reaction rod protection device. Background Technology

[0002] In the process of lightweighting heavy-duty trucks, the reaction rods on the chassis need to be replaced with lightweight alloys (such as aluminum alloys) instead of traditional steel. However, during the chassis assembly and tilting process, the reaction rods must withstand the tilting impact from the entire chassis, making the lightweight alloy reaction rods highly susceptible to bending or even breakage during tilting. This problem not only wastes parts and increases production costs but also seriously affects the production cycle of the final assembly line. When the chassis is tilted at the assembly line tilting station, the aluminum alloy reaction rods undergo elastic deformation under the impact of the chassis's gravity. Furthermore, if the two lifting straps in contact with the reaction rods are not synchronized during lifting, a large impact force will be generated, further increasing the risk of bending or breakage of the reaction rods. Utility Model Content

[0003] This utility model addresses the problem of reaction rods being easily bent and broken during the chassis flipping process in heavy truck assembly lines. It designs and manufactures a reaction rod protection device, which improves production efficiency, reduces scrap costs caused by broken reaction rods, and ensures the safety of operators during assembly. The device is easy to operate, has a wide range of applications, and can ensure the safety of aluminum alloy reaction rods for different vehicle models during flipping operations.

[0004] This utility model provides the following solution:

[0005] In a first aspect, this utility model discloses a reaction rod protection device, which is sleeved on the reaction rod. The protection device includes:

[0006] First connecting plate;

[0007] The second connecting plate has its front end vertically connected to the upper end of the first connecting plate;

[0008] The third connecting plate has its front end vertically connected to the lower end of the first connecting plate, and its rear end is detachably connected to the rear end of the second connecting plate by fasteners.

[0009] The first connecting plate is located in front of the reaction rod, the second connecting plate is located above the reaction rod, the third connecting plate is located below the reaction rod, and the fastener is located behind the reaction rod.

[0010] Preferably, the left and right ends of the reaction rod are mounted on both sides of the vehicle frame via the pin, the left and right ends of the first connecting plate are tightly fitted to the front end of the pin, and there is a gap between the middle of the first connecting plate and the middle of the reaction rod.

[0011] Preferably, the first connecting plate has protrusions at both the left and right ends, and the protrusions have first supporting ribs at both the upper and lower ends, with the inner side of the protrusions and the front end of the pin tightly fitted together.

[0012] Preferably, a second supporting rib is provided between the protrusion and the middle part of the first connecting plate.

[0013] Preferably, the second connecting plate and the third connecting plate extend rearward to form a first lug and a second lug, and the fastener includes:

[0014] Nut, which is fixed to the second lug;

[0015] A screw, the first end of which is connected to a lever, and the second end of which passes through the first lug and is screwed to the nut.

[0016] Preferably, the first connecting plate has a stress relief groove in the middle.

[0017] Preferably, the gap between the inner side of the middle part of the first connecting plate and the middle part of the reaction rod is 0.9-1.2mm.

[0018] Preferably, the thickness of the first connecting plate, the second connecting plate and the third connecting plate is 4-6 mm.

[0019] Secondly, this utility model discloses a vehicle frame tilting device, comprising:

[0020] A tilting machine and a lifting sling, the lifting sling being installed below the tilting machine;

[0021] The reaction rod is installed on the frame, and the aforementioned reaction rod protective device is sleeved on the reaction rod. The inner side of the sling contacts the outer side of the reaction rod protective device, causing the frame to rotate.

[0022] This utility model has the following advantages compared with the prior art:

[0023] 1. This utility model designs a protective device that moves together with the reaction rod. The protective device contacts the sling of the flipping device, avoiding direct contact between the reaction rod and the flipping device. This reduces the risk of damage to the reaction rod located inside the protective device during the flipping operation and provides safety assurance for the entire assembly process.

[0024] 2. Because there is a gap between the middle of the protective device and the middle of the reaction rod, the left and right ends of the protective device are tightly fitted to the front end of the pin. When the lifting strap of the flipping device drives the reaction rod to flip, it first squeezes the middle of the protective device inward. The middle of the protective device then transmits the force to the front end of the pin on both sides, thereby ensuring the stability of the reaction rod during the flipping process and effectively preventing the reaction rod from bending or breaking due to excessive force.

[0042] Example 1

[0043] See Figure 1-7 As shown, the reaction rod protection device provided in this embodiment of the application is sleeved on the reaction rod 4, and the protection device includes:

[0044] First connecting plate 1;

[0045] The second connecting plate 2 is vertically connected to the upper end of the first connecting plate 1 at its front end.

[0046] The third connecting plate 3 has its front end vertically connected to the lower end of the first connecting plate 1, and its rear end is detachably connected to the rear end of the second connecting plate 2 via fasteners.

[0047] The first connecting plate 1 is located in front of the reaction rod 4, the second connecting plate 2 is located above the reaction rod 4, the third connecting plate 3 is located below the reaction rod 4, and the fastener is located behind the reaction rod 4.

[0048] By positioning the first connecting plate 1 in front of the reaction rod 4, the second connecting plate 2 above the reaction rod 4, and the third connecting plate 3 below the reaction rod 4, with the fasteners located behind the reaction rod 4, it is ensured that the protective device moves along with the reaction rod during the frame tilting process. The protective device contacts the sling of the tilting device, avoiding direct contact between the reaction rod and the tilting device. This reduces the risk of damage to the reaction rod located inside the protective device during the tilting operation, providing safety assurance for the entire assembly process.

[0049] See Figure 1-7 As shown, the left and right ends of the reaction rod 4 are mounted on both sides of the frame via pins 5. The left and right ends of the first connecting plate 1 are tightly fitted to the front end of the pin 5. There is a gap between the middle of the first connecting plate 1 and the middle of the reaction rod 4.

[0050] Because there is a gap between the middle of the first connecting plate 1 and the middle of the reaction rod 4, the left and right ends of the first connecting plate 1 are tightly attached to the front end of the pin 5. When the sling of the flipping device drives the reaction rod to flip, it first squeezes the middle of the protective device inward. The middle of the first connecting plate 1 transmits the force to the front end of the pin 5 on both sides, thereby ensuring the stability of the reaction rod 4 during the flipping process and effectively preventing the reaction rod 4 from bending or breaking due to excessive force.

[0051] See Figure 1-7 As shown, the first connecting plate 1 has protrusions at both the left and right ends, and the protrusions have first supporting ribs 11 at both the upper and lower ends. The inner side of the protrusions and the front end of the pin 5 are tightly fitted together.

[0052] The left and right ends of the first connecting plate 1 have protrusions relative to the middle to accommodate the shape of the pin 5. In this embodiment, at least two first support ribs 11 are welded to one end of the first connecting plate 1, located above and below the pin respectively, which play a certain role in protecting the pin and can also prevent the protrusion from deforming during use due to the tight fit between the inner side of the protrusion and the front end of the pin 5, thus affecting the protective effect.

[0053] See Figure 1-4 As shown, a second support rib 12 is provided between the protrusion and the middle part of the first connecting plate 1.

[0054] The second support rib 12 is fixed to the first connecting plate 1 by welding, which can further enhance the strengthening effect and prevent the protrusion from deforming.

[0055] See Figure 3-7 As shown, the second connecting plate 2 and the third connecting plate 3 extend rearward to form a first lug and a second lug, and the fasteners include:

[0056] Nut 6, Nut 6 is fixed on the second lug;

[0057] Screw 7, with a lever 8 connected to the first end of screw 7, and the second end of screw 7 passing through the first lug and screwed into nut 6.

[0058] The first and second lugs extend rearward from the rear ends of the second connecting plate 2 and the third connecting plate 3, and the nut 6 and the screw 7 are installed thereon. This allows the protective device to be detachably installed on the reaction rod 4. A rectangular pawl 8 is welded to the first end of the screw 7 for easy disassembly and assembly.

[0059] See Figure 1 , 2 As shown in Figures 5, 6, and 7, the first connecting plate 1 has a stress relief groove 9 in the middle.

[0060] Stress relief grooves 9 can be provided in the transition area between the middle part of the first connecting plate 1 and the two end protrusions to release stress and prevent the plate from breaking.

[0061] Furthermore, the gap between the inner side of the middle portion of the first connecting plate 1 and the middle portion of the reaction rod 4 is 0.9-1.2 mm. In this embodiment, the distance between the inner side of the middle portion of the first connecting plate 1 and the middle portion of the reaction rod 4 is 1 mm, which provides good protection.

[0062] Furthermore, the thickness of the first connecting plate 1, the second connecting plate 2, and the third connecting plate 3 is 4-6mm. In this embodiment, 5mm sheet metal is selected, which is precision laser-cut and then sheet metal forming is completed using a bending machine to obtain the connected first connecting plate 1, second connecting plate 2, and third connecting plate 3. The first supporting rib 11 and the second supporting rib 12 are connected to the first connecting plate 1 by a segmented welding process to enhance the stability and reliability of the structure. It is also necessary to deburr the corners of each part of the protective device to eliminate sharp edges and burrs, thereby improving the safety of the device and the convenience of assembly.

[0063] Example 2

[0064] The vehicle frame tilting device provided in this application includes:

[0065] Tilting machine and lifting slings, with the lifting slings installed below the tilting machine;

[0066] See Figure 7 As shown, the middle part of the pin 5 passes through both ends of the reaction rod 4, the front end of the pin 5 is tightly fitted with both ends of the first connecting plate 1, and the side end of the pin 5 is fixed on the frame body. The aforementioned reaction rod protection device is sleeved on the reaction rod 4. In this embodiment, two reaction rods 4 are installed at both the front and rear ends of the frame body. When the entire frame is lifted by two slings, the two slings are respectively located between the overall centerline of the frame and the centerline of the two protection devices. The inner side of the slings contacts the outer side of the reaction rod protection device, causing the entire frame to rotate.

[0067] The usage process of this utility model is as follows:

[0068] The first connecting plate 1 is tightly fitted to the pins 5 on the frame at both ends, so that the reaction rod 4 is located inside the protective device. Then, the screw 7 is screwed through the first lug and the nut 6. The lever 8 is rotated to lock the screw 7 and the nut 6. The bottom of the lifting strap of the tipping device is then placed on the protective device. When the tipping machine lifts the frame, the middle of the first connecting plate 1 is subjected to lateral pressure instead of the reaction rod 4. At this time, the pins 5, which are tightly fitted to both ends of the first connecting plate 1, bear the force first, thereby protecting the internal reaction rod 4 and preventing it from deforming. After the frame has completed a stable tipping, the lifting strap is removed, the screw 7 and the nut 6 are loosened, and the protective device is removed. At this time, the reaction rod body has no deformation, ensuring the integrity and usability of the reaction rod.

[0069] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
