Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame transportation, in particular to a heavy truck frame transportation manipulator. Background Art

[0002] The heavy-duty truck frame is a frame-type structure that spans the front and rear axles of the truck, commonly known as the beam. It is the base of the truck and is similar to the human skeleton. The heavy-duty truck frame is an important component of the heavy-duty truck and plays a key role in load-bearing and support, allowing each assembly to maintain a relatively correct installation position and carry various loads inside and outside the truck. At the same time, it also needs to withstand various forces and moments from the road, engine, steering, and braking. During the long-term use of heavy-duty trucks, the frame, as a key component of load-bearing and support, will experience wear and aging. In order to maintain the performance and safety of the vehicle, the frame needs to be regularly inspected, maintained, and replaced as necessary. Moving the frame is a prerequisite for these maintenance work.

[0003] After searching, a Chinese patent with application number CN202022707136.X discloses a vehicle for transporting heavy-duty truck batteries. The existing technology is mostly to set up battery replacement equipment similar to a crane in the battery swap station, which requires the truck to be parked precisely at the predetermined position. In addition, the battery replacement equipment is bulky, the running track is fixed, the installation and construction of the whole set of equipment is complicated, and the cost is very high. The truck must be parked precisely at the predetermined position, so the replacement of heavy-duty truck batteries is mainly completed by a transport cart, which is simple to implement, low cost, and does not require the truck to be parked at the preset accurate position.

[0004] The above makes it easy to use a transport cart to transport heavy truck batteries, while when transporting a heavy truck frame, it is usually necessary to manually transport the frame to the transport cart and then transport it. When the frame is transported manually, due to the heavy truck frame's heavy weight and large size, manual transportation not only makes the labor intensity high, but also makes it difficult to limit and fix the frame in the hands due to fatigue, which poses a high safety risk and easily leads to low transportation efficiency, thereby creating the risk of frame damage.

The stabilizer bar is used to help limit the frame and improve the tightness of the frame on the clamping block. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] As attached Figure 1-6 As shown, the utility model provides an embodiment: a heavy truck frame handling manipulator includes a stretching frame 1, and a clamping structure is provided at the bottom of the stretching frame 1;

[0033] The clamping structure includes a mounting shaft 2, the number of which is set to four, two mounting shafts 2 are rotatably connected to the two sides of the stretching frame 1, a connecting box 3 is fixedly connected between the two mounting shafts 2, both sides of the connecting box 3 are fixedly connected to connecting shafts 4, and the two connecting shafts 4 are fixedly connected to clamping blocks 7, a mounting box 5 is arranged below the stretching frame 1, two clamping blocks 7 are slidably connected to the outside of the mounting box 5, two limiting grooves 6 are provided on both sides of the mounting box 5, the connecting shaft 4 and the mounting shaft 2 are slidably connected to the inside of the limiting groove 6, and an outer tube 8 is fixedly connected to the inside of one of the connecting boxes 3, Another connecting box 3 is fixedly connected to the inside of an inner column 10, and the inner column 10 is arranged inside an outer tube 8. The inside of the outer tube 8 is fixedly connected to a first spring 9, and one end of the first spring 9 is fixedly connected to one end of the inner column 10. A protective pad 11 is arranged on the outside of the clamping block 7, and the protective pad 11 is made of rubber. The mounting shaft 2 facilitates the connection between the stretching frame 1 and the connecting box 3, and the limiting groove 6 facilitates the limiting of the sliding connecting shaft 4 and the mounting shaft 2. The inner column 10 and the outer tube 8 facilitate the limiting protection of the first spring 9, and the protective pad 11 facilitates the protection of the contact surface of the clamped frame body 19.

[0034] As attached Figure 4 As shown, a protective structure is provided on one side of the clamping block 7, and the protective structure includes a rotating block 12, and the number of the rotating blocks 12 is set to two. The rotating block 12 is rotatably connected to one side of the clamping block 7, and a first stabilizing bar 13 is fixedly connected to one side of the rotating block 12, and a second stabilizing bar 15 is fixedly connected to the other side of the rotating block 12. One end of the second stabilizing bar 15 is rotatably connected to two auxiliary wheels 14, and the two connecting boxes 3 are slidably connected inside the installation box 5. The first stabilizing bar 13 and the second stabilizing bar 15 are convenient for limiting the clamped frame body 19 to improve stability, and the auxiliary wheels 14 are convenient for reducing the contact surface between the frame body 19 and the clamping block 7 for protection, thereby reducing the generation of friction.

[0035] As attached Figure 6As shown, two outer shells 16 and two second springs 18 are fixedly connected to the lower surface of the installation box 5. The second springs 18 are arranged inside the outer shell 16. The inner shell 17 is slidably connected inside the outer shell 16.

[0037] Working principle: When clamping the frame body 19 during transportation, the pull ring 21 is lifted up, so that the pull ring 21 drives the connecting block 20 and thus drives the stretching frame 1 to stretch. When the stretching frame 1 stretches, it drives the installation shaft 2 to slide inside the limiting groove 6, so that the installation shaft 2 drives the connecting boxes 3 inside the installation box 5 to approach each other. When the connecting boxes 3 approach each other, the connecting shaft 4 is driven to approach each other, so that the connecting shaft 4 drives the two clamping blocks 7 to approach each other, thereby facilitating the clamping of the frame body 19 to be clamped, thereby reducing the difficulty of transporting the frame body 19;

[0038] When the frame body 19 is clamped, under the rotation action of the rotating block 12, it is convenient to rotate according to the concave and convex surface of the frame body 19 when it is clamped, so as to improve the stability of the frame body 19 by using the first stabilizing bar 13 and the second stabilizing bar 15. At the same time, when the frame body 19 is clamped, under the action of the auxiliary wheel 14, it is convenient to reduce the friction between the frame body 19 and the clamping block 7, and by the action of the second spring 18, it is convenient to push the rotating block 12, so as to enhance the tightness of the clamping.
