Description

Technical Field

[0001] The invention relates to the technical field of inverted arch slag cleaning, and in particular discloses a tunnel inverted arch slag cleaning device and method. Background Art

[0002] As the speed of high-speed rail increases, the quality requirements for tunnel construction are also increasing. In the construction of the inverted arch of the tunnel, the workers first need to dig a foundation pit in the inverted arch soil layer, and then build the initial support in the foundation pit. Before the inverted arch support, the loose slag in the foundation pit needs to be cleaned to ensure that the combination of concrete and tunnel can meet the quality requirements, and then the inverted arch can be poured. The traditional cleaning method uses manual cleaning, which has a high workload for the workers. In addition, due to the uneven surface of the foundation pit, it is difficult for the workers to clean, and it is easy to cause the cleaning to be not clean.

[0003] For example, the invention with patent number 2023208705698 discloses a mechanized cleaning device for tunnel invert slag, comprising: a main body; a cleaning head, the cleaning head is arranged at one end of the main body, and detachable bristles are provided on the cleaning head; a connecting piece, the connecting piece is arranged at the end of the main body away from the cleaning head, and two pins are provided on the connecting piece, and the two pins correspond to the quick connector for connecting the excavator. The existing cleaning device fixes the bristles on the excavator, which requires a high level of proficiency of the workers driving the excavator during cleaning, and the foundation pit is recessed relative to the invert soil layer and the invert body. Therefore, for the workers driving the excavator, the corner close to the excavator is in a visual blind spot, which is not easy to clean. At the same time, the cleaned slag is inconvenient to collect. Although it can improve the efficiency of cleaning slag, it is relatively inconvenient to clean the slag. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a tunnel invert slag cleaning device and method to solve the technical problem that the existing slag cleaning device needs to be operated by staff when cleaning the foundation pit, and there will be visual blind spots, which makes it inconvenient when cleaning is needed.

[0009] Furthermore, the fixed ends of the two sets of third hydraulic cylinders are respectively fixedly connected to the two ends of the second connecting frame, and the telescopic ends of the two sets of third hydraulic cylinders are both provided with matching blocks.

[0012] Furthermore, a hydraulic station is provided on the base, to which the two sets of first hydraulic cylinders, the second hydraulic cylinders, the two sets of third hydraulic cylinders, the first hydraulic rotary cylinder, and the second hydraulic rotary cylinder are all connected. The hydraulic station is used to provide hydraulic oil to enable the two sets of first hydraulic cylinders, the second hydraulic cylinders, the two sets of third hydraulic cylinders, the first hydraulic rotary cylinder, and the second hydraulic rotary cylinder to operate normally.

[0013] A method for using a tunnel invert slag cleaning device comprises the following steps: S1: The tunnel inverted arch slag cleaning device is first moved to a designated position in the tunnel by the first four-wheel drive device. Then, the staff determines whether horizontal adjustment is required. If adjustment is required, the first hydraulic cylinder is activated to drive the second four-wheel drive device to move downward until the second four-wheel drive device contacts the bottom surface and the first four-wheel drive device is separated from the bottom surface. The tunnel inverted arch slag cleaning device is then adjusted by the second four-wheel drive device. After the adjustment is completed, the first hydraulic cylinder is retracted to the initial position, so that the first four-wheel drive device contacts the bottom surface and the second four-wheel drive device is separated from the bottom surface. S2: Start the second hydraulic rotary cylinder, which drives the first connecting frame to rotate 180 degrees around the fixed base through the connecting shaft and then stops. Then, the second hydraulic cylinder drives the second connecting frame and the two sets of fixed frames to descend, so that the second connecting frame and the two sets of fixed frames are located in the foundation pit. At this time, the inductive contact wire brush contacts the surface of the foundation pit, and the dust suction port is close to the surface of the foundation pit; S3: Start the inductive contact wire brush and the vacuum suction device, the inductive contact wire brush cleans the surface of the foundation pit, and the vacuum suction device sucks the slag into the collection box through the dust suction port; at the same time, start the first hydraulic rotary cylinder, the first hydraulic rotary cylinder drives the telescopic rod to rotate through the second movable seat, the telescopic rod drives the inductive contact wire brush and the dust suction port to move on the surface of the foundation pit, and at the same time, the dust suction port and the inductive contact wire drive the movable column to move on the two sets of fixed frames, and at the same time, the telescopic rod is extended and retracted as the dust suction port and the inductive contact wire move; S4: When the inductive contact wire brush and the dust suction port reach the other end, the first hydraulic rotary cylinder stops rotating, and then one of the third hydraulic cylinders drives the first movable seat to move on the second connecting frame, thereby driving the telescopic rod to move the inductive contact wire brush and the dust suction port horizontally, but the distance moved by the inductive contact wire brush and the dust suction port is slightly less than the length of the inductive contact wire brush, and then the third hydraulic cylinder is stopped, and the first hydraulic rotary cylinder is started in reverse, and the entire surface of the foundation pit is cleaned by this reciprocating motion.

[0014] S5: When the slag in the collection box accumulates to a certain extent, the drive motor is started. The drive motor drives the threaded rod to rotate in the fixed sleeve through the output shaft, and the slag is moved from the collection box through the fixed sleeve and the second connecting pipe to the slag stacking area through the rotation of the threaded rod.

[0015] The staff only needs to remotely control the tunnel invert slag cleaning device to automatically clean the surface of the pit foundation. At the same time, the cleaning can avoid the uneven surface of the pit foundation causing incomplete cleaning. At the same time, the cleaning speed is always kept constant, making cleaning more convenient.

[0016] The working principle and beneficial effects of this solution are: When cleaning the pit foundation, the tunnel invert slag cleaning device is first moved to the designated position through the driving mechanism, and then the surface of the pit foundation is automatically cleaned by the automatic cleaning mechanism. When cleaning the surface of the pit foundation, the cleaning component can move along the arc of the pit foundation. At the same time, the inductive contact wire brush can automatically adjust along with the uneven surface of the pit foundation to ensure that incomplete cleaning will not occur. The surface of the pit foundation can be cleaned without excessive human intervention, making the cleaning of the foundation pit more convenient.

[0017] When the automatic cleaning mechanism is not being cleaned, it is located above the base. When cleaning is required, the second hydraulic rotary cylinder is used to drive the automatic cleaning mechanism to flip over so that it is located above the pit foundation. The second hydraulic cylinder is then used to cooperate with the automatic cleaning mechanism to drive it down, so that the inductive contact wire brush contacts the surface of the foundation pit. At the same time, the suction port can also suck the cleared slag into the collection box, thereby improving the adaptability of the tunnel invert slag cleaning device and being able to quickly move the inductive contact wire brush to the designated position, making cleaning more convenient.

[0026] A method for using a tunnel invert slag cleaning device comprises the following steps: S1: The tunnel inverted arch slag cleaning device is moved longitudinally to a designated position in the tunnel via the first four-wheel drive device 202. The staff then observes the position of the tunnel inverted arch slag cleaning device to determine whether lateral adjustment is required. If lateral adjustment is required, the first hydraulic cylinder 205 is activated, and the telescopic end of the first hydraulic cylinder 205 extends, driving the first connecting frame 204 and the second four-wheel drive device 203 to move downward until the second four-wheel drive device 203 contacts the bottom surface. The first hydraulic cylinder 205 continues to extend, while the second four-wheel drive device 203 remains stationary. The first four-wheel drive device 202 and the base 201 are separated from the bottom surface, and then the first hydraulic cylinder 205 is stopped and the second four-wheel drive device 203 is started. The second four-wheel drive device 203 drives the tunnel inverted arch slag cleaning device to move horizontally until it moves to the specified position, and then the first hydraulic cylinder 205 is retracted until the first hydraulic cylinder 205 is retracted to the initial position. At this time, the first four-wheel drive device 202 is in contact with the bottom surface, and the second four-wheel drive device 203 is separated from the bottom surface. At this time, the state of the tunnel inverted arch slag cleaning device is as follows: Figure 3 shown.

[0027] S2: Start the second hydraulic rotating cylinder 322, the second hydraulic rotating cylinder 322 drives the connecting shaft 323 to rotate, and the connecting shaft 323 drives the first connecting frame 204 to rotate around the fixed seat 301 until the first connecting frame 204 rotates 180 degrees, and then stop the second hydraulic rotating cylinder 322. At this time, one side of the first connecting frame 204 is in contact with one side of the fixed seat 301; then start the second hydraulic cylinder 303, the second hydraulic cylinder 303 drives the second connecting frame 304 and the two sets of fixed frames 305 to descend, until they descend to the appropriate position, and then stop the second hydraulic cylinder 303. At this time, the inductive contact wire brush 402 is in contact with the surface of the foundation pit 103, and the dust suction port 401 is close to the surface of the foundation pit 103. At this time, the state of the tunnel invert arch slag cleaning device is as follows: Figure 1 shown.

[0028] S3: Start the inductive contact wire brush 402 and the vacuum suction device 404. The inductive contact wire brush 402 can automatically clean the surface of the foundation pit 103 according to the line shape of the interface surface. It can ignore the unevenness of the surface of the foundation pit 103 and clean the surface of the foundation pit 103. The vacuum suction device 404 sucks the slag swept out by the inductive contact wire brush 402 through the suction port 401, and moves the slag sucked by the suction port 401 to the collection box 405 through the first connecting pipe 403.

[0029] S4: Start the first hydraulic rotating cylinder 310, the first hydraulic rotating cylinder 310 drives the second movable seat 309 to rotate, the second movable seat 309 drives the telescopic rod 307 to rotate around the second movable seat 309, and the telescopic end of the telescopic rod 307 drives the inductive contact wire brush 402 and the dust suction port 401 to clean the surface of the foundation pit 103. When the dust suction port 401 and the inductive contact wire brush 402 move, they drive the movable column 324 to move on the two sets of fixed frames 305, so the moving trajectory of the inductive contact wire brush 402 and the dust suction port 401 is the same as the shape of the fixed frame 305. Since the fixed frame 305 is not an arc intercepted in a circle, the telescopic rod 307 will also extend and retract when the inductive contact wire brush 402 and the dust suction port 401 move.

[0030] S5: When the inductive contact wire brush 402 and the dust suction port 401 move from one end of the foundation pit 103 to the other end, the first hydraulic rotating cylinder 310 is stopped, and then the third hydraulic cylinder 306 connected to the first movable seat 308 is started. The third hydraulic cylinder 306 drives the first movable seat 308 to move on the second connecting frame 304, and the second connecting frame 304 drives the inductive contact wire brush 402 and the dust suction port 401 to slide a short distance on the movable column 324 through the telescopic rod 307. At this time, a small section of the inductive contact wire brush 402 is located on the surface of the foundation pit 103 after cleaning. Then the third hydraulic cylinder 306 is stopped, and the first hydraulic rotating cylinder 310 is started again. At this time, the rotation direction of the first hydraulic rotating cylinder 310 is opposite to the previous rotation direction. In this reciprocating manner, the two groups of third hydraulic cylinders 310 cooperate with the first movable seat 308 to clean the entire surface of the foundation pit 103.

[0031] S6: When the slag in the collecting box 405 accumulates to a certain height, the driving motor 407 is started. The driving motor 407 drives the threaded rod 408 to rotate in the fixed sleeve 409 through the output shaft. The slag moves from the collecting box 405 to the fixed sleeve 409 through the dust collection hole 410. The slag in the fixed sleeve 409 moves through the threaded rod 408 and moves from the fixed sleeve 409 through the second connecting pipe 411 to the slag stacking area.

[0032] S7: When the surface of the foundation pit 103 is cleaned, the second hydraulic cylinder 303 is started, and the telescopic end drives the second connecting frame 304 and the matching frame 320 to rise until the second hydraulic cylinder 303 shrinks to the initial position, and then the second hydraulic rotating cylinder 322 is started to drive the first connecting frame 204 to rotate on the fixed seat 301, so that the automatic cleaning mechanism moves from above the foundation pit 103 to above the base 201.

[0033] When the first movable seat 308 is separated from one of the third hydraulic cylinders 306 and fixed to the other third hydraulic cylinder 306, the first movable seat 308 first drives the two groups of connecting blocks 312 to move to the matching frame 320. The second matching grooves 315 in the two groups of connecting blocks 312 are respectively slidably inserted into the two groups of matching frames 320. The two groups of second matching grooves 315 slide on the matching frames 320. The connecting block 312 follows the shape of the matching frame 320. While the connecting block 312 slides along the matching frame 320, the matching frame 320 slides horizontally in the second matching grooves 315. The second matching grooves 315 cooperate with the matching frame 320 to make the connecting block 312 rotate around the hinge seat. 312 always remains vertical.
