[0002] The utility model relates to the field of open caisson construction equipment, and specifically refers to a shaft boring robot and a pressed open caisson earth excavation device. Background Art
[0003] At present, the traditional construction techniques for deep vertical shafts include the traditional open cut method and the traditional caisson construction. In the traditional caisson construction, the soil below the cutting edge is excavated, and the caisson sinks by its own weight. The measures for reducing the resistance of the caisson wall include making the side wall smooth, applying heavy oil, applying paraffin wax, applying clay slurry, etc. Traditional caissons are prone to problems such as sudden sinking of the structure, uneven sinking, inclination, and large ground settlement and deformation. In recent years, some new techniques and methods have emerged continuously to improve the traditional caisson technique, mainly including the press-in caisson method, the pneumatic caisson method, the VSM (submersible shaft tunneling machine), etc. However, the new techniques still have problems such as difficulty in controlling ground settlement, difficulty in controlling the attitude of the caisson, low degree of mechanization and automation, and low construction efficiency. After retrieval, Chinese Patent CN115928780A discloses an invention patent named an actively controlled prefabricated mechanized caisson system. This patent includes a propulsion suspension device, a pipeline reel device, a floating platform, an underwater excavation device, a prefabricated caisson main body, a grouting device, a control device, a mud-water device, and a visualization interface; several propulsion suspension devices are respectively arranged at intervals on the ground around the well body, and the prefabricated caisson main body is suspended or pressed down into the well body through several propulsion suspension devices; the floating platform floats on the water surface inside the prefabricated caisson main body, and a hollow structure is formed in the middle of the floating platform, so that the underwater excavation device is suspended below the floating platform and located at the bottom of the prefabricated caisson main body. The pipeline of the underwater excavation device passes upward through the hollow structure, penetrates the floating platform, and then leads out of the prefabricated caisson main body and winds around the pipeline reel device. The pipeline reel device is arranged on the ground beside the well body; both the grouting device and the mud-water device are arranged on the ground outside the well body. The grouting device grouts between the well wall and the outer wall of the prefabricated caisson main body, and the mud-water device is connected to the underwater excavation device; the control device is electrically connected to the propulsion suspension device, the pipeline reel device, the floating platform, the underwater excavation device, the prefabricated caisson main body, the grouting device, the mud-water device, and the visualization interface respectively. The underwater excavation device includes a fixed base, a turntable assembly, a robotic arm assembly, a swing driving member, a dredging pump, and a lifting driving member; the fixed base is fixedly installed at the top center of the cross beam of the prefabricated caisson main body, and the turntable assembly is rotatably installed on the fixed base; the lifting driving member is fixedly installed on the turntable assembly, and one end of the robotic arm assembly is rotatably connected to the driving end of the lifting driving member through a first pin shaft. The bottom of the robotic arm assembly is rotatably connected to the ear plate on the turntable assembly through a second pin shaft near the lifting driving member, so that the robotic arm assembly can rotate horizontally synchronously with the turntable assembly and rotate vertically relative to the turntable assembly around the second pin shaft through the lifting driving member; the dredging pump is swingably installed at the other end of the robotic arm assembly through the swing driving member, so that the dredging pump can rotate, lift, or swing around the fixed base to excavate the soil, and the dredging pump is connected to the mud-water device;The swing drive is electrically connected to the underwater excavation hydraulic controller. The deficiencies of the above patent are as follows: First, the structure of the above patent is complex and requires many devices. In addition, in the above patent, the underwater excavation device is fixed at the top center of the cross beam of the caisson main body, which makes the underwater excavation device can only excavate near the center of the caisson main body. For caissons with a large diameter, it may not be able to excavate to the edge part of the caisson, resulting in a limited excavation range. Second, the underwater excavation device in the above patent adjusts the up and down position of the underwater excavation device through a lifter, which has a high usage cost. Moreover, when the underwater excavation device moves downward, it is impossible to maintain the stability of the underwater excavation device, and it is not convenient to adjust. Third, the caisson in the above patent requires several propulsion suspension devices to drive it to sink simultaneously. The propulsion suspension device has a complex structure, many components, troublesome operation, time-consuming and laborious, and increases the usage cost of shaft tunneling.

[0068] The mud discharge pipeline 30 of the utility model extends upward, passes through the upper platform 77 and extends out, and is placed outside the upper platform to form a mud discharge end.
[0069] As attached Figures 1 - 10 , an off-hole control system can be set on the upper platform 77 or a place far away from the caisson, the off-hole control system, the control system in the frame control cabin 59, and the control system in the mechanical arm control cabin 60, such as a PLC control system, the front and rear drive cylinders 5, the excavation rotation drive cylinder 10, the slurry pump 15, the leg drive cylinder 27, the mud discharge hydraulic butterfly valve 67 and the backwash hydraulic butterfly valve 69, the pressure sensor 70, the locking drive cylinder 73, and the through-core hydraulic cylinder 81 are all connected to the control system in the frame control cabin 59, the swing drive cylinder 12 and the reamer drive cylinder 14 are all connected to the control system in the mechanical arm control cabin 60, one end of the connecting cable 78 is connected to the control system in the frame control cabin 59, and the other end passes through the upper platform 77 to connect to the off-hole control system, and a camera can be set on the annular fixing seat 17 and the excavation arm 11 , lighting, sonar, are connected to the well control system through the rack control system, which is convenient for operators to control the shaft excavation robot in real time outside the well. Each driving cylinder can be a hydraulic cylinder. The slag conveying driving component can be a slurry pump 15 or a containing chamber and an air source. The air source can be a compressor. Through the continuous delivery of air, the mud suction pipeline absorbs the mud after the auger head 13 digs the well, enters the containing chamber, and then discharges it through the mud discharge pipeline 30. The two slag conveying driving components can be selected and set according to needs. This embodiment takes the slag conveying driving component as a slurry pump 15 as an example for explanation, as shown in the attached Figure 9 and attached Figure 10, before use, after selecting a location, dig a pit, lower the open caisson 21, and install the support frame 82, steel strand 83, and uplift pile 84 on the outer wall of the immersed 21. In this embodiment, 8 support frames 82 are arranged at intervals on the outer wall of the open caisson 21. A through-hole hydraulic cylinder 81 is installed on the support frame 82 and connected to the uplift pile 84 through the steel strand 83. The uplift pile 84 is on the ground outside the open caisson 21. The steel strand 83 is driven to move upward and locked by the through-hole hydraulic cylinder 81, shortening the distance between the support frame 82 and the uplift pile 84, applying a downward pressure to the open caisson 21 to make the open caisson sink. The out-of-well control system can timely understand the sinking amount of each direction of the open caisson 21 through the stroke of each through-hole hydraulic cylinder 81, and control and adjust the sinking amount of each direction of the open caisson 21 by controlling the stroke of the through-hole hydraulic cylinder 81, so as to ensure the verticality and stability of the open caisson 21 itself. After the adjustment is completed, the upper platform and the shaft tunneling robot are hoisted into the entrance of the open caisson 21 through the hoisting hole on the upper platform 77. Guide wheels 25 are installed on the outer wall of the annular fixing seat 17, and the guide wheels 25 slide down along the guide slideway 23 on the inner wall of the open caisson 21 until the adjusting leg 26 contacts the caisson support beam 24. The leg fixing pin 74 on the caisson support beam 24 is inserted into the fixing pin through-hole 75 at the lower end of the adjusting leg 26 to limit the shaft tunneling robot 22 in the open caisson 21. The shaft tunneling robot 22 can drive the adjusting leg 26 to extend or retract through the leg driving cylinder 27 to adjust the height between the shaft tunneling robot 22 and the bottom of the open caisson 21. The caisson support beam 24 is a cross beam, so four excavation holes are formed between the caisson support beam 24 and the bottom of the pit, which is convenient for the robot to excavate.
[0070] The operation steps are as follows:
[0071] Step 1: Place the annular fixing seat 17 into the open caisson 21 through a crane or other lifting equipment, make the guide wheel 25 of the annular fixing seat 17 slidably connected to the guide slideway 23, make the lower end of the adjusting leg 26 abut against the upper end surface of the caisson support beam 24, insert the leg fixing pin 74 into the fixing pin through-hole 75 at the lower end of the adjusting leg 26 to fix the position of the shaft tunneling robot 22 in the open caisson 21, and place the upper platform 77 on the upper end of the open caisson 21 through a crane or other lifting equipment. The mud discharge pipeline 30 passes through the upper platform 77 and extends out to be connected to the slag discharge box for convenient slag discharge;
[0072] Step 2: The operator controls the entire pressed open caisson soil extraction device through the out-of-well control system.
[0073] Before and after starting the driving cylinder 5, drive the reamer head 13 to move back and forth. Move it above an excavation hole of the caisson support beam 24. The excavation arm 11 is a telescopic robotic arm that can be telescoped. Correspondingly, the mud suction pipeline 29 can be set as a telescopic pipeline to facilitate telescoping with the excavation arm 11. Start the excavation arm 11 to make the reamer head 13 contact the bottom of the pit. Start the reamer drive cylinder 14 and the slurry pump 15 to start excavating and taking soil. The reamer head 13 can rotate 360° driven by the excavation rotation drive cylinder 10. At the same time, the swing drive cylinder 12 can change the excavation angle of the reamer head 13. When an excavation hole is completed, that is, when the reamer head 13 can no longer contact the soil at the bottom of the pit, start the front and rear drive cylinder 5 to adjust the front and rear position of the reamer head 13, or release the locking drive cylinder 73 to make the locking drive cylinder 73 drive the locking claw 72 to open, release the clamping of the annular slide rail 20. The track wheel drive motor of the frame rotation mechanism 16 drives the track wheel 18 to rotate, thereby driving the frame 1 to rotate, and then driving the reamer head 13 to rotate. Adjust the reamer head 13 to another excavation hole and perform excavation and soil taking as above. After excavation, dig the next excavation hole until the four excavation holes formed by the caisson support beam 24 are dug out. The soil at the lower end of the caisson 21 collapses into the excavation holes, and the caisson 21 moves downward under its own gravity. At the same time, start the through-hole hydraulic cylinder 81 to make the caisson 21 move downward smoothly under its own gravity and the action of the through-hole hydraulic cylinder 81. The annular fixed seat 17 moves downward along the guiding slideway 23 on the inner wall of the caisson 21 through the guide wheel 25, and the adjusting legs move downward accordingly. At the same time, start the leg drive cylinders 27 of the four adjusting legs 26 at the lower end of the annular fixed seat 17. The four adjusting legs 16 are circumferentially distributed below the annular fixed seat 17. Adjust the length of each adjusting leg 27 to keep the annular fixed seat 17 in a horizontal state. Then continue to start excavating the four excavation holes on the caisson 21 as above until the excavation and soil taking operation of the caisson is completed;
[0074] Step 3: Use a crane or a lifting device to remove the upper platform 77 and the annular fixed seat 17 from the caisson 21.
[0075] The structure of the utility model is ingenious and easy to operate. Compared with the prior art, the first point is that by setting the soil-taking front-and-back moving mechanism 3, the shaft tunneling robot 22 can move back and forth, improving the working efficiency of shaft tunneling. At the same time, it can dig a large-diameter caisson, reducing the cost of shaft construction. The second point is that the utility model is provided with adjusting legs 26, and the length of the adjusting legs 26 is adjusted to maintain the stability of the whole robot operation, indirectly improving the shaft tunneling operation efficiency. Thirdly, the utility model is also provided with a frame rotating mechanism 16, enabling the whole frame 1 to rotate, improving the flexibility of the robot operation. At the same time, the frame 1 and the annular fixed seat 17 are limited and fixed by the rotation locking mechanism 71, which can avoid the shaking of the robot during operation, improving the stability and sustainability of the operation. In addition, the excavation arm 11 can also rotate through the excavation rotation drive cylinder 10, broadening the operation range of the robot and enabling faster and better excavation. The fourth point is that in the utility model, the caisson 21 can sink through gravity fall and the caisson downward pressure driving mechanism 80. By monitoring the stroke of the through-hole hydraulic cylinders 81 in all directions on the outside of the caisson 21, the deviation of the sinking amount in all directions of the caisson is corrected, controlling the verticality of the well body and ensuring the stability of the well body descent. The stretching or locking of the steel strand by the through-hole hydraulic cylinder adopts the prior art. The through-hole hydraulic cylinder includes three driving cylinders connected up, middle and down. The upper and lower hydraulic cylinders are used to clamp or loosen the steel strand, and the middle hydraulic cylinder is used to stretch the steel strand. The fifth point is that in the utility model, the mud discharge pipeline 30 includes a first mud discharge pipeline 62 and a second mud discharge pipeline 63, and the first mud discharge pipeline 62 and the second mud discharge pipeline 63 are slidably connected. This not only broadens the mud discharge channel, but also guides the front-and-back movement of the frame 1 through the second mud discharge pipeline 63. In addition, the utility model is provided with a mud discharge hydraulic butterfly valve 67 on the first mud discharge pipeline 62, an anti-flushing pipeline 68 is arranged on one side of the first mud discharge pipeline 62, and an anti-flushing hydraulic butterfly valve 69 is installed on the anti-flushing pipeline 68. A pressure sensor 70 is installed on the second mud discharge pipeline 63, and the pipeline pressure is monitored in real time through the pressure sensor 70 to ensure that the system works under good pressure conditions, improving the working efficiency of the equipment. When the pipeline pressure is abnormal, clean water with a pressure of 1 Mpa can be used to clean the underwater pipeline, reducing the water outlet maintenance of the equipment pipeline and improving the anti-silting ability of the pipeline.The backwashing operation can be achieved by controlling the opening and closing of the sludge discharge hydraulic butterfly valve 67 and the backwashing hydraulic butterfly valve 69. The operation is simple, and the mud conveying capacity of the pipeline is improved. Specifically: During the sludge discharge operation: the sludge discharge hydraulic butterfly valve 67 is opened, and the backwashing hydraulic butterfly valve 69 is closed. The mud-water mixture passes through the second sludge discharge pipeline 63, the first sludge discharge pipeline 62, the sludge discharge hydraulic butterfly valve 67, and then is discharged into the slag discharge tank through the pipeline connected to the slag discharge tank; During the backwashing operation: when the pipeline pressure feedback by the pressure sensor 70 in the pipeline is abnormal or backwashing operation of the pipeline is required, the sludge discharge hydraulic butterfly valve 67 is closed, and the backwashing hydraulic butterfly valve 69 is opened. External clean water passes through the backwashing pipeline 68, the backwashing hydraulic butterfly valve 69, the first sludge discharge pipeline 62, and the second sludge discharge pipeline 63 to perform reverse pipeline cleaning; Sixthly, the present utility model also provides a slip ring underwater protection mechanism 31 and an optical fiber slip ring connection protection mechanism to protect the electro-hydraulic slip ring and the optical fiber slip ring. The electro-hydraulic slip ring 39 is arranged in the isolation space 45 to avoid the influence of water vapor and salt mist. The optical fiber communication transmission signal is stable and has strong anti-interference ability. However, the optical fiber slip ring is also not suitable for the environment with water vapor and oil. The optical fiber slip ring 38 of the present utility model is arranged in the mud pipeline 36 through the optical fiber slip ring protective shell 44, which improves the compressive capacity of the optical fiber slip ring. Moreover, on the premise of ensuring the communication quality, the inner diameter of the mud pipeline 36 of the present utility model can be set larger to achieve the mud transportation of large pipelines.
[0076] Due to the adoption of the above structure, the present utility model has the advantages of novel structure, large excavation range, high flexibility, good stability, high working efficiency, and low cost.
