Description

Technical Field

[0001] This application relates to the field of trenching construction, and in particular to a deviation monitoring and correction device for trenching construction in hard rock strata. Background Technology

[0002] Trenching is a common underground engineering operation method widely used in infrastructure construction such as subways, tunnels, and underground parking lots. This construction method uses a trenching machine to excavate trenches of a certain width and depth in underground rock strata, providing a foundation for subsequent construction of diaphragm walls or installation of supporting structures.

[0003] The trenching machine is the core equipment for trenching construction, typically including main components such as the trenching cutter head, suction pipe, and drag chain. The trenching cutter head is used to cut the rock strata, the suction pipe is used to remove rock cuttings and mud generated during the trenching process, and the drag chain is used to connect the traction equipment to ensure the stable movement of the trenching machine during construction. To ensure the verticality and accuracy of the trenching machine during construction, existing trenching machines are usually equipped with a correction device. These correction devices mainly use correction plates and hydraulic rods installed on the trenching machine. When the trenching machine deviates, the hydraulic rods drive the correction plates to abut against the inner wall of the trench, and the external force restores the trenching machine to the correct position.

[0004] However, in practical applications, in order not to obstruct the normal movement of the milling machine, the correction plate can only be retracted into the milling machine. When correction is needed, the correction action can usually only be triggered after the milling machine has deviated to a certain extent. This results in a certain delay in the correction response. Secondly, when the correction plate is in contact with the inner wall of the groove, it will generate a large resistance to the normal movement of the milling machine. Utility Model Content

[0005] The purpose of this application is to address the problems mentioned in the background art, namely that in order not to obstruct the normal movement of the milling machine, the correction plate can only be retracted into the milling machine, and when correction is needed, the correction action can usually only be triggered after the milling machine has deviated to a certain extent, which results in a certain delay in the correction response. Furthermore, when the correction plate is in contact with the inner wall of the groove, it will generate a large resistance to the normal movement of the milling machine. This application provides a deviation monitoring and correction device for milling construction in high-hardness rock strata.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A deviation monitoring and correction device for trenching construction in hard rock strata includes a trenching machine. Two symmetrical trenching cutters are rotatably connected to one end of the trenching machine. A suction pipe is fixed to the trenching machine. Two symmetrical drag clips are fixed to the end of the trenching machine away from the trenching cutters. Two pendulum deflection meters are fixed to the trenching machine and embedded within it. A deviation correction and adjustment mechanism is provided on the trenching machine. The mechanism includes four support rods symmetrically embedded in pairs on the trenching machine. A support frame is fixed to one end of each support rod. An adjusting wheel is rotatably connected to the support frame. A rotating component is provided between the support rod and the trenching machine. A moving component is provided between the support rod and the trenching machine. A cleaning component is provided between the support frame and the adjusting wheel.

[0007] By adopting the above technical solution, four adjusting wheels are installed inside the milling machine. After the milling machine enters the underground, the adjusting wheels are always in contact with the inner wall of the trench. During correction, the four adjusting wheels work together to push the inner wall of the trench, allowing the milling machine to complete the correction. This enables the milling machine to correct the deviation in a timely manner and reduces the possibility that the correction plate would have been in contact with the inner wall of the trench during correction, which would have affected the normal movement of the milling machine.

[0008] Furthermore, the rotating assembly includes a rotating rod fixed on a support rod, with rotating seats rotatably connected to both ends of the rotating rod, and the rotating seats being fixedly connected to the milling machine.

[0009] By adopting the above technical solution, the rotating rod supports the support rod, and the rotating rod rotates on the two rotating seats, which makes it easy for the support rod to drive the adjusting wheel to extend out of the milling machine.

[0010] Furthermore, the movable component includes a connecting block one fixed on the milling machine, a connecting block two fixed on the support rod, and a movable hydraulic rod disposed between the connecting block one and the connecting block two.

[0011] By adopting the above technical solution, the moving hydraulic rod between connecting block one and connecting block two pushes the support rod, thereby enabling the support rod to rotate under the support of the rotating rod.

[0012] Furthermore, a rotating block is rotatably connected to the first connecting block, and the rotating block is fixedly connected to the movable hydraulic rod. A rotating block is rotatably connected to the second connecting block, and the rotating block is fixedly connected to the telescopic end of the hydraulic telescopic rod.

[0013] By adopting the above technical solution, when the moving hydraulic rod pushes the support rod, rotating block one and rotating block two rotate on the corresponding connecting block one and connecting block two, thereby reducing the possibility of jamming when the moving hydraulic rod pushes the support rod.

[0014] Furthermore, the cleaning assembly includes two support plates symmetrically fixed on a support frame, with a cleaning blade fixed between the two support plates, the cleaning blade abutting against an adjusting wheel.

[0015] By adopting the above technical solution, the mud on the surface of the adjusting wheel is scraped off by the cleaning blades on the two support plates, thereby reducing the amount of mud adhering to the adjusting wheel and affecting its normal rotation.

[0016] Furthermore, the cleaning blade has two symmetrical bevels facing away from the milling machine.

[0017] By adopting the above technical solution, the mud shoveled off by the cleaning blade is moved towards both ends of the cleaning blade by the action of the two inclined planes, thus making it easier for the mud to detach from the cleaning blade.

[0018] Furthermore, the pendulum deflection meter is equipped with a protective cover, which is threadedly connected to the milling machine.

[0019] By adopting the above technical solution, the pendulum deflection meter is embedded and fixed in the milling machine, and then a protective cover is threaded onto the embedded groove of the milling machine. This allows for timely detection of the milling machine's deviation and enables the pendulum deflection meter to operate normally within the milling groove.

[0020] Furthermore, two symmetrical reinforcing rods are fixed on the support frame, and the end of the reinforcing rod away from the support frame is rotatably connected to the rotating block.

[0021] By adopting the above technical solution, two reinforcing rods are fixed on the support frame, and the reinforcing rods are used to provide further auxiliary support to the support frame, thereby further improving the stability of the adjusting wheel and increasing the stability of the support rods and the support frame.

[0022] In summary, this application includes at least one of the following beneficial effects; 1. This application, after a portion of the milling machine enters the ground, has two lower adjusting wheels on the upper part of the milling machine go underground. The moving component drives the support rod, which, supported by the rotating component, opens. The support frame on the support rod drives the adjusting wheel to contact the inner wall of the milled groove, allowing the adjusting roller to roll along the inner wall and follow the milling machine. After the milling machine is fully in the ground, all four adjusting wheels open, contacting the inner wall of the groove and descending. A pendulum angle meter on the milling machine monitors the angle of the milling machine in real time. When the milling machine deviates, the moving component on the four adjusting wheels drives the support rod, which in turn drives the adjusting wheel on the support frame. Based on the deviation angle, the adjusting wheel contacts the inner wall of the groove, and with the support of the adjusting wheel, the milling machine returns to its original position. This achieves the goal of enabling the milling machine to correct deviations promptly, reducing the possibility of slow correction response, and minimizing the possibility of the correction plate contacting the inner wall of the groove during correction, which could affect the normal movement of the milling machine.

[0023] 2. In this application, when the adjusting wheel rotates on the inner wall of the milling groove, mud will adhere to the adjusting wheel. When the adjusting wheel rotates, it passes through the cleaning scraper between the two support plates. The cleaning scraper removes the mud from the surface of the adjusting wheel. Under the action of the two inclined planes, the mud removed by the cleaning scraper moves to both ends of the cleaning scraper and then detaches from the cleaning scraper. This achieves the purpose of easily removing mud from the adjusting wheel and reducing the mud adhering to the adjusting wheel, thus affecting the rotation of the adjusting wheel.

[0026] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0027] This application discloses a deviation monitoring and correction device for trenching construction in hard rock strata.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A deviation monitoring and correction device for trenching construction in hard rock formations includes a trenching machine 1. Two symmetrical trenching cutter heads 2 are rotatably connected to one end of the trenching machine 1. A suction pipe 3 is fixed on the trenching machine 1. Two symmetrical drag buckles 4 are fixed to the end of the trenching machine 1 away from the trenching cutter heads 2. Two pendulum deflection meters 5 are fixed on the trenching machine 1 and embedded in the trenching machine 1. A deviation correction and adjustment mechanism 6 is provided on the trenching machine 1. The deviation correction and adjustment mechanism 6 includes four support rods 61 that are symmetrically embedded in pairs on the trenching machine 1. A support frame 62 is fixed to one end of the support rod 61. An adjustment wheel 63 is rotatably connected to the support frame 62. A rotating component 64 is provided between the support rod 61 and the trenching machine 1. A moving component 65 is provided between the support rod 61 and the trenching machine 1. A cleaning component 66 is provided between the support frame 62 and the adjustment wheel 63.

[0029] During the trenching construction of the high-strength quartz strata, the trenching machine 1 is vertically lowered into the ground for trenching work. After part of the trenching machine 1 has entered the ground, the two lower adjusting wheels 63 of the trenching machine 1 enter the ground. The moving component 65 drives the support rod 61, which, supported by the rotating component 64, opens. The support frame 62 on the support rod 61 drives the adjusting wheels 63 to contact the inner wall of the trench, allowing the adjusting rollers to roll along the inner wall and follow the trenching machine 1. After the trenching machine 1 has completely entered the ground, all four adjusting wheels 63 are fully opened, allowing the adjusting wheels 63 to contact the inner wall of the trench and descend. The pendulum angle meter 5 on the trenching machine 1 is used to monitor the angle of the trenching machine 1 in real time. When the trenching machine 1 deviates, the angle is monitored. When the milling machine 1 is aligned, the moving components 65 on the four adjusting wheels 63 drive the support rod 61, which in turn drives the adjusting wheels 63 on the support frame 62. The adjusting wheels 63 then contact the inner wall of the trench according to the offset angle. With the support of the adjusting wheels 63, the milling machine 1 returns to its original position. By setting four adjusting wheels 63 inside the milling machine 1, the adjusting wheels 63 remain in contact with the inner wall of the trench after the milling machine 1 enters the underground. During the correction process, the four adjusting wheels 63 work together to push the inner wall of the trench, allowing the milling machine 1 to complete the correction. This enables the milling machine 1 to correct its deviation in a timely manner and reduces the possibility that the correction plate would contact the inner wall of the trench during the correction process, thus affecting the normal movement of the milling machine 1.

[0030] Reference Figure 1 , Figure 2 and Figure 3The rotating assembly 64 includes a rotating rod 642 fixed on a support rod 61. Both ends of the rotating rod 642 are rotatably connected to a rotating seat 641, and the rotating seat 641 is fixedly connected to the milling machine 1.

[0031] In addition, the movable component 65 includes a first connecting block 652 fixed on the milling machine 1, a second connecting block 653 fixed on the support rod 61, and a movable hydraulic rod 651 provided between the first connecting block 652 and the second connecting block 653.

[0032] Furthermore, a rotating block 654 is rotatably connected to the connecting block 652, and the rotating block 654 is fixedly connected to the movable hydraulic rod 651. A rotating block 655 is rotatably connected to the connecting block 653, and the rotating block 655 is fixedly connected to the telescopic end of the hydraulic telescopic rod.

[0033] After the milling machine 1 enters the ground, the telescopic end of the movable hydraulic rod 651 on the connecting block 1 652 extends, allowing the movable hydraulic rod 651 to push the rotating block 2 655. The rotating block 2 655 pushes the connecting block 2 653, which in turn pushes the support rod 61. The support rod 61 drives the rotating rod 642 to rotate on the two rotating seats 641, causing the support rod 61 to drive the support frame 62. The support frame 62 then drives the adjusting wheel 63 to abut against the inner wall of the milling groove, allowing the adjusting wheel 63 to roll on the inner wall of the milling groove. When the milling machine 1 deviates, the four hydraulic telescopic rods work together to extend the adjusting wheel 63 out of or retract it into the milling machine 1. With the support of the adjusting wheel 63, the milling machine 1 is corrected. By having the adjusting wheel 63 on the milling machine 1 constantly contact the inner wall of the groove and roll on the inner wall, the possibility of the original correction plate contacting the inner wall of the groove and affecting the normal movement of the milling machine 1 can be reduced. At the same time, the correction can be responded to in a timely manner, reducing the possibility of slow correction response.

[0034] Reference Figure 2 and Figure 3 The cleaning component 66 includes two support plates 661 symmetrically fixed on the support frame 62, and a cleaning blade 662 is fixed between the two support plates 661. The cleaning blade 662 abuts against the adjusting wheel 63.

[0035] In addition, the cleaning blade 662 has two symmetrical bevels, which face away from the milling machine 1.

[0036] When the adjusting wheel 63 rotates on the inner wall of the milling groove, mud will stick to it. As the adjusting wheel 63 rotates, it passes through the cleaning scraper 662 between the two support plates 661. The cleaning scraper 662 scrapes off the mud from the surface of the adjusting wheel 63. Under the action of the two inclined planes, the mud scraped off by the cleaning scraper 662 moves to both ends of the cleaning scraper 662 and then detaches from the cleaning scraper 662. By setting the cleaning scraper 662 on the support frame 62, the adjusting wheel 63 passes through the cleaning scraper 662 when it rotates, which makes it easy to scrape off the mud on the adjusting wheel 63, reducing the mud adhering to the adjusting wheel 63 and affecting its rotation.

[0037] Reference Figure 1 and Figure 2 The pendulum deflection meter 5 is equipped with a protective cover 7, which is threadedly connected to the milling machine 1. The pendulum deflection meter 5 is embedded and fixed in the milling machine 1, and then a protective cover 7 is threadedly connected to the embedded groove of the milling machine 1. The protective cover 7 protects the pendulum deflection meter 5 on the milling machine 1. By installing the pendulum deflection meter 5 on the milling machine 1 and protecting it with the protective cover 7, the deviation of the milling machine 1 can be detected in time, and the pendulum deflection meter 5 can operate normally in the milling groove.

[0038] Reference Figure 2 and Figure 3 Two symmetrical reinforcing rods 8 are fixed on the support frame 62. The end of the reinforcing rod 8 away from the support frame 62 is rotatably connected to the rotating block. By fixing the two reinforcing rods 8 on the support frame 62, when the support rod 61 supports the support frame 62, the reinforcing rods 8 provide further auxiliary support to the support frame 62. By allowing the reinforcing rods 8 to rotate on the rotating block, the reinforcing rods 8 move with the support frame 62, allowing the reinforcing rods 8 to support the support frame 62, thereby further improving the stability of the adjusting wheel 63 and increasing the stability of the support rod 61 and the support frame 62.

[0039] Working Principle: During the trenching construction of high-strength quartz strata, the trenching machine 1 is vertically lowered into the ground for trenching work. After part of the trenching machine 1 has entered the ground, the two adjusting wheels 63 on the upper part of the trenching machine 1 enter the ground. The telescopic end of the movable hydraulic rod 651 on the connecting block 1 652 extends, causing the movable hydraulic rod 651 to push the rotating block 2 655. The rotating block 2 655 pushes the connecting block 2 653, which in turn pushes the support rod 61. The support rod 61 drives the rotating rod 642 to rotate on the two rotating seats 641, causing the support rod 61 to drive the support frame 62. The support frame 62 then drives the adjusting wheels 63 to contact the inner wall of the trench, allowing the adjusting wheels 63 to roll within the trench. When the trenching machine 1 has completely entered the ground, the upper adjusting wheels 63... Wheel 63 also abuts against the inner wall of the milling groove. Mud will stick to the adjusting wheel 63. When the adjusting wheel 63 rotates, it passes through the cleaning blade 662 between the two support plates 661. The cleaning blade 662 scrapes off the mud on the surface of the adjusting wheel 63. The mud scraped off by the cleaning blade 662 moves to both ends of the cleaning blade 662 under the action of the two inclined planes. Then the mud leaves the cleaning blade 662. When the milling machine 1 is completely underground, the pendulum deflection meter 5 monitors the angle of the milling machine 1 in real time. When the pendulum deflection meter 5 detects the deviation, the adjusting wheel 63 moves with the milling machine 1. The four hydraulic telescopic rods cooperate to make the adjusting wheel 63 extend out of the milling machine 1 or retract into the milling machine 1. The milling machine 1 is corrected under the real-time support of the adjusting wheel 63.
