Description

Technical Field

[0001] This utility model relates to the field of dredging and lifting technology, specifically an adaptive lifting worktable for a sedimentation tank dredging robot. Background Technology

[0002] Sedimentation tank dredging refers to the maintenance work of removing sediments such as silt and suspended solids that have accumulated in the sedimentation tank over a long period of time. Sedimentation tanks allow impurities in the water to settle naturally by letting them stand. However, the continuous accumulation of sediments will reduce the tank capacity and water treatment efficiency. Therefore, dredging needs to be carried out regularly. This operation is commonly seen in sewage treatment plants, industrial wastewater treatment facilities, and rainwater collection tanks. The specific dredging frequency needs to be determined comprehensively based on water quality, treatment volume, and sediment formation rate. The core purpose is to ensure the normal operation of the sedimentation tank and maintain its effective separation function of suspended solids.

[0003] Currently known lifting mechanisms for dredging robot working devices are all fixed hinge point flipping structures. This means the slurry pump and agitator are mounted on a frame structure, with two hinge points extending from this structure on either side. Under the action of hydraulic cylinders, the working device rotates around these fixed hinge points, achieving the purpose of lifting and lowering the device. However, in this fixed hinge point structure, the angle of the pump inlet changes with the position during the flipping process. If the angle is too large, it can cause the slurry pump to suck in air, resulting in the slurry material moving away from the agitator. Furthermore, the hydraulic lines of the slurry pump and agitator experience significant bending due to the large-angle flipping, making pipeline layout difficult, resulting in excessively long and messy pipelines. Therefore, we provide an adaptive lifting platform for sedimentation tank dredging robots. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adaptive lifting work platform for a sedimentation tank sludge removal robot.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive lifting worktable for a sedimentation tank sludge removal robot, comprising a drive robot, with multiple pulleys rotatably connected to both sides of the outer wall of the drive robot, and multiple walking belts rotatably connected to both sides of the outer wall of the drive robot; a collection chamber fixedly connected to the top surface of the drive robot, and a flexible hose fixedly connected to one side of the top of the collection chamber; a sludge removal device movably connected to the outer side of the collection chamber via the flexible hose; an upper limiting rod and a lower limiting rod fixedly connected inside the drive robot; multiple upper curved connecting rods rotatably connected to both ends of the outer wall of the upper limiting rod, and multiple hydraulic telescopic rods rotatably connected to both ends of the outer wall of the upper limiting rod; and multiple lower curved connecting rods fixedly connected to both ends of the outer wall of the lower limiting rod.

[0006] As described above, one end of the hose is fixedly connected to the top side of the collection chamber, and the other end of the hose is fixedly connected to the center of the top surface of the dredging equipment. The inner cavity of the collection chamber is connected to the inner cavity of the dredging equipment through the hose.

[0007] As mentioned above, the walking belt is flat, and multiple anti-slip protrusions are fixedly connected to the outer wall of the walking belt.

[0008] As described above, the inner wall of each pulley is fixedly connected with multiple anti-detachment teeth, and the outer wall of each pulley is provided with multiple anti-detachment grooves, with the outer wall of the anti-detachment teeth and the inner wall of the anti-detachment grooves meshing with each other.

[0009] As described above, one end of the upper curved connecting rod is rotatably connected to one side of the outer wall of the dredging equipment via a rotating shaft, and the other end of the upper curved connecting rod is rotatably connected to one end of the outer wall of the upper limiting rod.

[0010] As described above, the end of the lower zigzag connecting rod away from the lower limiting rod is rotatably connected to one side of the outer wall of the dredging equipment via a rotating shaft, and the ends of the lower zigzag connecting rod and the lower limiting rod maintain equal vertical distances.

[0011] As described above, the telescopic end of the hydraulic telescopic rod is rotatably connected to the top surface of the lower limiting rod via a rotating shaft.

[0012] Compared with existing technologies, this adaptive lifting platform for sedimentation tank sludge removal robots has the following advantages:

[0013] I. When the hydraulic telescopic rod of this utility model extends or retracts, the height of the dredging equipment can be adjusted by the linkage between the upper and lower curved connecting rods while maintaining the vertical position of the equipment. This ensures that the pump suction port remains parallel to the bottom of the sedimentation tank, avoiding cavitation caused by excessive angle. At the same time, the hydraulic pipeline moves vertically with the equipment and only needs to be arranged in the vertical direction, greatly reducing the bending range, simplifying pipeline design, avoiding excessively long or messy pipelines, reducing maintenance difficulty, and optimizing the posture of the dredging equipment during the lifting and lowering process.

[0014] II. The robot driven by this utility model moves by using pulleys on both sides and a walking belt. The walking belt is flat and has anti-slip protrusions on its outer wall to enhance grip. The anti-detachment teeth on the inner wall of the pulley and the anti-detachment groove on the outer wall engage with each other to prevent the belt from falling off.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6 As shown, this utility model provides a technical solution: an adaptive lifting workbench for a sedimentation tank sludge removal robot, including a drive robot 1. Multiple pulleys 101 are rotatably connected to both sides of the outer wall of the drive robot 1, and multiple walking belts 102 are rotatably connected to both sides of the outer wall of the drive robot 1. A collection chamber 103 is fixedly connected to the top surface of the drive robot 1, and a hose 104 is fixedly connected to one side of the top of the collection chamber 103. A sludge removal device 105 is movably connected to the outer side of the collection chamber 103 through the hose 104. An upper limiting rod 2 and a lower limiting rod 201 are fixedly connected inside the drive robot 1. Multiple upper curved connecting rods 202 are rotatably connected to both ends of the outer wall of the upper limiting rod 2, and multiple hydraulic telescopic rods 203 are rotatably connected to both ends of the outer wall of the upper limiting rod 2. Multiple lower curved connecting rods 204 are fixedly connected to both ends of the outer wall of the lower limiting rod 201.

[0025] When the hydraulic telescopic rod 203 extends or retracts, the height of the dredging equipment 105 can be adjusted by the linkage between the upper curved connecting rod 202 and the lower curved connecting rod 204 while keeping the vertical state of the dredging equipment 105 unchanged. This ensures that the pump suction port is always parallel to the bottom of the sedimentation tank. At the same time, the hydraulic pipeline moves vertically with the equipment and only needs to be arranged in the vertical direction, which greatly reduces the bending amplitude, simplifies the pipeline design, and optimizes the posture of the dredging equipment 105 during the lifting and lowering process.

[0026] like Figure 1 As shown, one end of the outer wall of the hose 104 is fixedly connected to one side of the top of the collection chamber 103, and the other end of the outer wall of the hose 104 is fixedly connected to the center of the top surface of the dredging device 105. The inner cavity of the collection chamber 103 is connected to the inner cavity of the dredging device 105 through the hose 104.

[0027] The hose 104 is fixedly connected to the collection chamber 103 and the dredging equipment 105 at both ends, so that the sediment such as mud and suspended solids collected by the dredging equipment 105 during operation can flow directly into the collection chamber 103 for temporary storage through the hose 104. This avoids the risk of blockage caused by angle changes in traditional rigid pipe connections. At the same time, the flexibility of the hose 104 can also adapt to the positional changes of the dredging equipment 105 when it is raised and lowered, ensuring the continuity and stability of the transportation process.

[0028] like Figure 1 As shown, the walking belt 102 is flat, and multiple anti-slip protrusions 106 are fixedly connected to the outer wall of the walking belt 102.

[0029] The flat walking belt 102 increases the contact area with the sediment at the bottom of the sedimentation tank. Combined with the anti-slip protrusions 106 on the outer wall, it can improve the gripping ability of the drive robot 1 on silt and slippery tank bottoms.

[0030] like Figure 1 As shown, multiple anti-detachment teeth 107 are fixedly connected to the inner wall of the pulley 101, and multiple anti-detachment grooves 108 are opened on the outer wall of the pulley 101. The outer wall of the anti-detachment teeth 107 and the inner wall of the anti-detachment grooves 108 engage with each other.

[0031] The anti-detachment teeth 107 on the inner wall of the pulley 101 and the anti-detachment groove 108 on the outer wall engage with each other, which can effectively prevent the walking belt 102 from falling off the pulley 101 when the walking belt 102 is running or when the bottom of the pool is in a complex condition.

[0032] like Figure 1 As shown, one end of the upper curved connecting rod 202 is rotatably connected to one side of the outer wall of the dredging equipment 105 via a rotating shaft, and the other end of the upper curved connecting rod 202 is rotatably connected to one end of the outer wall of the upper limiting rod 2.

[0033] The upper curved connecting rod 202 is connected to the dredging equipment 105 and the upper limit rod 2 respectively through the rotating shaft. When the hydraulic telescopic rod 203 extends or retracts, it can provide top support force for the dredging equipment 105.

[0034] like Figure 1 As shown, the lower zigzag connecting rod 204 is rotatably connected to one side of the outer wall of the dredging equipment 105 via a rotating shaft at one end away from the lower limit rod 201, and the ends of the lower zigzag connecting rod 204 and the upper zigzag connecting rod 202 maintain equal vertical distances.

[0035] The ends of the lower zigzag connecting rod 204 and the upper zigzag connecting rod 202 maintain equal vertical distances. When the hydraulic telescopic rod 203 extends and retracts to drive the lower limit rod 201 to move, the lower zigzag connecting rod 204 and the upper zigzag connecting rod 202 will move synchronously with the same vertical displacement, forming a parallelogram-shaped linkage structure.

[0036] like Figure 1 As shown, the telescopic end of the hydraulic telescopic rod 203 is rotatably connected to the top surface of the lower limit rod 201 via a rotating shaft.

[0037] The telescopic end of the hydraulic telescopic rod 203 is connected to the lower limit rod 201 via a rotating shaft, so that the linear thrust of the hydraulic telescopic rod 203 can be smoothly transmitted to the lower limit rod 201. Combined with the linkage between the lower zigzag connecting rod 204 and the upper zigzag connecting rod 202, the lifting height of the dredging equipment 105 can be precisely controlled.

[0038] Working principle: The flexible hose 104 is fixedly connected to the collection chamber 103 and the dredging equipment 105 at both ends, allowing the sediment such as mud and suspended solids collected by the dredging equipment 105 during operation to flow directly into the collection chamber 103 for temporary storage via the flexible hose 104. This avoids the risk of blockage caused by angle changes in traditional rigid pipe connections. The flexible hose 104 also adapts to the positional changes of the dredging equipment 105 during lifting, ensuring the continuity and stability of the transport process. The flat walking belt 102 increases the contact area with the sediment at the bottom of the sedimentation tank. Combined with the anti-slip protrusions 106 on the outer wall, it enhances the gripping ability of the drive robot 1 on silt and slippery tank bottoms. The anti-detachment teeth 107 on the inner wall of the pulley 101 and the anti-detachment grooves 108 on the outer wall mesh with each other, effectively preventing the walking belt 102 from slipping off the belt when it is running or when the tank bottom conditions are complex. The pulley 101 detaches, and the upper zigzag connecting rod 202 is connected to the dredging equipment 105 and the upper limit rod 2 via a rotating shaft. When the hydraulic telescopic rod 203 extends or retracts, it can provide top support for the dredging equipment 105. The ends of the lower zigzag connecting rod 204 and the upper zigzag connecting rod 202 maintain equal vertical distances. When the hydraulic telescopic rod 203 extends or retracts, driving the lower limit rod 201 to move, the lower zigzag connecting rod 204 and the upper zigzag connecting rod 202 will move synchronously with the same vertical displacement, forming a parallelogram-shaped linkage structure. The extension end of the hydraulic telescopic rod 203 is connected to the lower limit rod 201 via a rotating shaft, so that the linear thrust of the hydraulic telescopic rod 203 can be smoothly transmitted to the lower limit rod 201. Combined with the linkage of the lower zigzag connecting rod 204 and the upper zigzag connecting rod 202, the lifting height of the dredging equipment 105 can be precisely controlled.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
