[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1-5 The present invention provides the following technical solution:

[0022] Specifically, it refers to an auxiliary device for relocating a mobile foamed asphalt plant mixing and recycling equipment, including a base frame 1. The bottom of the base frame 1 is equipped with four moving wheels 2 for movement. The upper side of the base frame 1 is equipped with a recycling device 3 for mixing foamed asphalt. In use, the moving wheels 2 facilitate the relocation of the recycling device 3, allowing the recycling device to be used in different locations and improving the utilization effect of the recycling device.

[0023] Hydraulic cylinders 4 are installed at the four corners of the bottom of the base frame 1. Support legs 5 are installed at the bottom of the telescopic rods of the hydraulic cylinders 4. When the regeneration equipment 3 moves to the designated position, the hydraulic cylinders 4 are activated, and the telescopic rods of the hydraulic cylinders 4 push the support legs 5 downward. When the bottom of the support legs 5 contacts the ground, the telescopic rods of the hydraulic cylinders 4 continue to push the support legs 5. Because the support legs 5 are in contact with the ground, the base frame 1, the moving wheels 2, and the regeneration equipment 3, etc., move upward as a whole under the reaction force, so that the moving wheels 2 are lifted off the ground. This ensures the stability of the plant mixing and regeneration equipment.

[0024] The front side of the bottom frame 1 is equipped with a towing ring 13 for attaching a trailer hook. The towing ring 13 is attached to the trailer hook of the trailer, and the trailer tows the entire foamed asphalt plant mixing and recycling equipment to another location.

[0025] A mounting plate 6 is provided at the bottom of the front side of the base frame 1. A movable groove 7 is provided on the front surface of the mounting plate 6. A bidirectional screw 8 is rotatably connected in the movable groove 7. Two moving blocks 9 are threaded on the outer surfaces of the two threads of the bidirectional screw 8. Both moving blocks 9 slide in the movable groove 7. Two hinge seats 10 are provided on the front surface of the two moving blocks 9. Two push plates 11 are hinged on the two hinge seats 10. A U-shaped seat 12 is hinged on the side of the two push plates 11 away from the hinge seat 10. The traction ring 13 is hinged to the U-shaped seat 12.

[0026] When the foamed asphalt plant mixing and recycling equipment is moved to the designated position, the bidirectional screw 8 is rotated. At this time, the two moving blocks 9 move in opposite directions under the transmission of the threads of the bidirectional screw 8. During the displacement of the moving blocks 9, a pulling force is generated on the push plate 11. The push plate 11 simultaneously pulls the U-shaped seat 12 and the traction ring 13 to move closer to the bottom frame 1. The above structure reduces the footprint of the transfer traction auxiliary equipment and minimizes the impact of the traction ring 13 on the staff around the foamed asphalt plant mixing and recycling equipment. When the foamed asphalt plant mixing and recycling equipment needs to be transferred, the bidirectional screw 8 is reversed. At this time, the two moving blocks 9 move in opposite directions, thereby pushing the push plate 11 to push the U-shaped seat 12 and the traction ring 13 to move away from the bottom frame 1. This facilitates the connection of the traction ring 13 with the trailer hook of the trailer.

[0027] A support plate 20 is provided on the rear surface of the U-shaped seat 12, and a support housing 21 is provided on the lower surface of the mounting plate 6. The rear side of the support plate 20 slides through the support housing 21. When the U-shaped seat 12 is displaced, the rear side of the support plate 20 slides in the support housing 21, which can provide support for the U-shaped seat 12 and prevent the U-shaped seat 12 from tilting downward.

[0028] The upper and lower inner walls of the movable trough 7 are provided with limiting grooves 14, and the upper and lower surfaces of the movable block 9 are provided with limiting sliders 15 that slide within the limiting grooves 14. When in use, the movable block 9 slides and the limiting sliders 15 slide within the limiting grooves 14, which further improves the stability of the movable block 9 and minimizes the problem of the movable block 9 detaching during traction of the foamed asphalt plant mixing and recycling equipment.

[0029] The lower surface of the left side of the mounting plate 6 is provided with a transmission groove 16 extending into the bottom frame 1. The left side of the movable groove 7 is connected to the transmission groove 16. The left end of the bidirectional screw 8 extends into the transmission groove 16 and is rotatably connected to the inner wall of the transmission groove 16. The left end of the bidirectional screw 8 is fitted with a gear 19. The right side surface of the support leg 5 is provided with an L-shaped plate 17. The upper side of the L-shaped plate 17 is provided with a rack 18. The upper side of the rack 18 extends into the transmission groove 16 and meshes with the gear 19.

[0030] When the hydraulic cylinder 4 pushes the support leg 5 downward, the L-shaped plate 17 simultaneously drives the rack 18 to move downward, thereby the rack 18 meshes with the gear 19 to rotate. At this time, the bidirectional screw 8 rotates synchronously with the gear 19, thereby pulling the traction ring 13 to move closer to the bottom frame 1. When the hydraulic cylinder 4 pulls the support leg 5 upward, the L-shaped plate 17 simultaneously drives the rack 18 to move upward, and the rack 18 meshes with the gear 19 to reverse, thereby pushing the traction ring 13 to move away from the bottom frame 1. Using the above structure, the footprint of the traction auxiliary equipment can be automatically reduced after the foamed asphalt mixing and recycling equipment is fixed. When the foamed asphalt mixing and recycling equipment needs to be moved, the traction auxiliary equipment automatically extends without manual control, improving the effectiveness of the auxiliary equipment.

[0031] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
