Description

Technical Field

[0001] This utility model belongs to the field of outrigger technology, and specifically relates to a hydraulic lifting outrigger structure for a transport vehicle. Background Technology

[0002] Outriggers are support devices used in mechanical engineering to enhance equipment stability. Their core functions include bearing equipment loads, suppressing deflection and deformation, and improving anti-overturning capacity. Their structural forms include box-type outriggers, sleeve-type outriggers, and multi-section articulated outriggers, and they are widely used in construction machinery such as concrete pump trucks and cranes.

[0003] In existing technologies, transport vehicles require outriggers to support them during unloading, improving stability and preventing swaying and tipping. However, these outriggers require workers to disembark and clear debris from the ground to prevent it from getting stuck and compromising the vehicle's stability. Workers then have to return to the vehicle to operate the outriggers, making the process inconvenient. Therefore, designing a hydraulic lifting outrigger structure for transport vehicles is a problem we need to solve. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic lifting outrigger structure for a transport vehicle.

[0005] To achieve the above objectives, this utility model provides a hydraulic lifting outrigger structure for a transport vehicle, including a transport vehicle connecting plate. A hydraulic rod and a bracket are hinged to one side of the transport vehicle connecting plate. A connector is fixedly connected to the end of the bracket away from the transport vehicle connecting plate. The end of the inner rod of the bracket is rotatably connected to the inside of the connector. A support plate is hinged inside the connector. Anti-slip texture is provided on the side of the support plate away from the connector. A cleaning component is used to clean the ground in contact with the outrigger structure, and the cleaning component is connected to the support plate.

[0006] In the above technical solution, two support rods are symmetrically connected to the outer end of the hydraulic rod, and the end of the support rod away from the hydraulic rod abuts against the outer wall of the support plate.

[0007] In the above technical solution, the cleaning component further includes two connecting inclined plates symmetrically installed on one side of the support plate, a connecting rod fixedly connected between the two connecting inclined plates, a tension spring sleeved on the outer wall of the connecting rod, a connecting block fixedly connected to the end of the tension spring away from the connecting rod, and the connecting block fixedly installed on the outer wall of the bracket.

[0008] In the above technical solution, further, two inclined grooves and a V-shaped groove are opened on the side of the two connecting inclined plates away from the connecting rod. An elastic band is fixedly connected inside the V-shaped groove, a slider is fixedly connected to one end of the elastic band, and a connecting frame is fixedly connected to the outer wall of the slider.

[0009] In the above technical solution, furthermore, pulleys are slidably connected inside both of the inclined grooves, and the pulleys are rotatably connected to the outer wall of the connecting frame.

[0010] In the above technical solution, a rotating shaft is rotatably connected between the two connecting frames, and a cleaning sleeve is sleeved on the outer wall of the rotating shaft, and the cleaning sleeve is fixedly connected between the two connecting frames.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting up a cleaning component, the outrigger structure can automatically clean up stones and other debris at the contact point between the support plate and the ground when the outrigger structure is deployed. This prevents stones and other debris from getting stuck between the support plate and the ground, which could affect the stability of the transport vehicle. Furthermore, it eliminates the need for staff to get off the transport vehicle to manually check and clean the stones and other debris before returning to control the deployment of the outrigger structure, making it more convenient for staff to use. At the same time, the cleaning component can automatically reset when the outrigger structure is retracted, ready for the next operation. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 2The diagram illustrates a hydraulic lifting outrigger structure for a transport vehicle, comprising a transport vehicle connecting plate 1 for mounting and fixing the outrigger structure to the transport vehicle. A hydraulic rod 2 and a bracket 3 are hinged to one side of the connecting plate 1. A connector 4 is fixedly connected to the end of the bracket 3 away from the connecting plate 1. The inner rod end of the bracket 3 is rotatably connected to the interior of the connector 4. A support plate 5 is hinged inside the connector 4. Anti-slip textures 6 are provided on the side of the support plate 5 away from the connector 4. A cleaning assembly is used to clean the ground in contact with the outrigger structure. The cleaning assembly is connected to the support plate 5. Two support rods 7 are symmetrically connected to the outer end of the hydraulic rod 2. The end of the support rod 7 away from the hydraulic rod 2 abuts against the outer wall of the support plate 5. The support rods 7 are used to support and limit the support plate 5 in the retracted state of the outrigger structure, ensuring that the support plate 5 is parallel to the transport vehicle connecting plate 1, thus reducing the floor space occupied by the retracted outrigger structure.

[0016] like Figures 1 to 3 As shown, the cleaning assembly includes two connecting inclined plates 11 symmetrically installed on one side of the support plate 5. A connecting rod 10 is fixedly connected between the two connecting inclined plates 11. A tension spring 9 is sleeved on the outer wall of the connecting rod 10. The tension spring 9 is used to apply tension to the support plate 5 through the connecting rod 10 and the connecting inclined plates 11. When the outrigger structure is deployed, it pulls the support plate 5, which is no longer supported by the support rod 7, to rotate, so that the part of the support plate 5 closest to the connecting frame 16 contacts the ground first. A connecting block 8 is fixedly connected to the end of the tension spring 9 away from the connecting rod 10. The connecting block 8 is fixedly installed on the outer wall of the bracket 3. Two inclined grooves 12 and a V-shaped groove are opened on the side of each of the two connecting inclined plates 11 away from the connecting rod 10. 13. An elastic band 14 is fixedly connected inside the V-groove 13. A slider 15 is fixedly connected to one end of the elastic band 14. A connecting frame 16 is fixedly connected to the outer wall of the slider 15. Pulleys 17 are slidably connected inside both inclined grooves 12. The pulleys 17 are used to reduce friction when moving inside the inclined grooves 12. The pulleys 17 are rotatably connected to the outer wall of the connecting frame 16. A rotating shaft 18 is rotatably connected between the two connecting frames 16. The rotating shaft 18 is used to reduce friction with the ground. A cleaning sleeve 19 is sleeved on the outer wall of the rotating shaft 18. The cleaning sleeve 19 is used to remove stones and other debris at the contact position between the support plate 5 and the ground. The cleaning sleeve 19 is fixedly connected between the two connecting frames 16.

[0017] Working principle: When the hydraulic rod 2 extends, it pushes the bracket 3 to rotate and descend through the connector 4. This causes the connector 4 to drive the support plate 5 to rotate and descend, gradually moving it away from the support rod 7 on the outer sleeve of the hydraulic rod 2. Consequently, the support plate 5 loses the support limit of the support rod 7, allowing the tension spring 9 to pull the support plate 5 to rotate through the connecting rod 10 and the connecting inclined plate 11. This causes the part of the support plate 5 near the connecting frame 16 to rotate downwards. As the hydraulic rod 2 continues to extend, the rotating shaft 18 on the connecting frame 16 first contacts the support plate 5 with the ground. As the support plate 5 continues to approach the ground, it drives the connecting inclined plate 11 to gradually approach the rotating shaft 18 on the connecting frame 16. This causes the connecting frame 16 to drive the pulley 17 to slide along the inclined groove 12 on the connecting inclined plate 11, allowing the slider 15 to slide along the V-shaped groove. The sliding section parallel to the groove 13 and the inclined groove 12 slides. At this time, the slider 15 pulls the elastic band 14 to extend, and the connecting frame 16 slides along the outer wall of the support plate 5, so that the connecting frame 16 drives the rotating shaft 18 and the cleaning sleeve 19 to slide together. The rotating shaft 18 will roll along the ground, reducing the friction during sliding and avoiding jamming. The cleaning sleeve 19 will scrape away stones and other debris on the ground, preventing the support plate 5 from contacting the ground later. When supporting the transport vehicle, stones and other debris will affect the stability of the support plate 5, so as to achieve the effect of automatically cleaning the part of the support plate 5 in contact with the ground. There is no need for the staff to get off the transport vehicle to manually check and clean the stones and other debris, and then return to the transport vehicle to control the outrigger structure to work and unfold, which is convenient for the staff to use. Furthermore, when the staff needs to retract the outrigger structure, the hydraulic rod 2 can be controlled to retract, causing the hydraulic rod 2 to drive the bracket 3 and support plate 5 to reset via the connector 4. During this process, the rotating shaft 18 will stop contacting the ground as the support plate 5 resets, causing the rotating shaft 18 to lose pressure. This allows the elastic band 14 to retract and pull the slider 15 to reset, allowing the slider 15 to drive the pulley 17 to slide and reset along the inside of the inclined groove 12 via the connecting frame 16. This allows the connecting frame 16 to drive the rotating shaft 18 and the cleaning sleeve 19 to reset, waiting for the next operation, thus achieving the effect of automatically resetting the cleaning components.
