Description

Technical Field

[0001] This utility model relates to a rear axle swing frame structure for a heavy-duty shovel truck, belonging to the technical field of shovel trucks. Background Technology

[0002] Currently, existing hydraulic support shovel pallet trucks require a drive axle to move the frame. However, the drive axle is mainly fixedly mounted on the frame. For some heavy-duty shovel pallet trucks, one wheel often becomes airborne on uneven underground surfaces. Due to the vehicle's weight, this causes the heavy-duty shovel pallet truck to have difficulty getting out of trouble and become unable to move. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a reasonably designed rear axle swing frame structure for heavy-duty shovel trucks that adopts a swing-type rear axle structure and can adapt to uneven road surfaces.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is a rear axle swing frame structure for a heavy-duty shovel truck, including a frame. A swing frame is installed in the middle of the drive axle mounting cavity of the frame. The middle part of the swing frame is rotatably mounted on the frame. Connecting holes for connecting the drive axle are provided on both sides of the swing frame. Limiting blocks are also installed on the upper sides of the swing frame. The limiting blocks are mounted on the frame.

[0005] Preferably, two sets of support beams are installed between the middle chambers of the frame, and a pin is installed between each set of support beams. The top of the swing frame is rotatably mounted on the pin via an ear seat. Fixed cover plates are installed on the two sets of support beams, and lifting handles are installed on the fixed cover plates.

[0006] Preferably, a reinforcing plate is also installed at the connection between the supporting beam and the frame, and the reinforcing plate is installed on the frame.

[0007] Compared with the prior art, the present invention has the following technical effects: The present invention has a simple structure and reasonable design. It adopts a swing frame structure on the frame and the drive axle is installed on the swing frame. In this way, the drive axle can swing left and right according to the road conditions under the action of the swing frame, so that the tires can better attach to the ground and improve the ability to get out of trouble.

[0011] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] like Figures 1 to 3 As shown, a heavy-duty shovel truck rear axle swing frame structure includes a frame 1. A swing frame 2 is installed in the middle of the drive axle mounting cavity of the frame 1. The middle of the swing frame 2 is rotatably mounted on the frame 1. Connection holes 3 for connecting the drive axle are provided on both sides of the swing frame 1. Limiting blocks 4 are also installed on the upper sides of the swing frame 2 and are mounted on the frame 1. Two sets of support beams 5 are installed between the middle cavities of the frame 1. A pin 6 is installed between each set of support beams 5. The top of the swing frame 2 is rotatably mounted on the pin 6 through an ear seat 7. Fixed cover plates 8 are installed on the two sets of support beams 5, and lifting handles 9 are installed on the fixed cover plates 8.

[0013] This invention employs a swing frame 2 mounted on a frame. The swing frame 2 is mounted on the support beam 5 of the frame 1 via lugs 7 and pins 6. The drive axle is directly bolted to the swing frame 2. When traveling on uneven surfaces, the drive axle can swing left and right under the action of the swing frame 2, quickly adapting to the terrain, preventing the tires from lifting off the ground, and improving traction. A limiting block 4 is installed on the frame 1 to control the swing amplitude of the swing frame 2. A reinforcing plate 10 is also installed at the connection between the support beam 5 and the frame 1, and is mounted on the frame 1. The reinforcing plate improves the connection strength at the joint and ensures structural stability.

[0014] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall be included within the scope of the present utility model.
