Description

Technical Field

[0001] The invention relates to the technical field of cutterhead cleaning, and in particular to a device for removing mud cake adhered to the cutterhead surface of a shield machine. Background Art

[0002] During the tunneling process of a shield machine in clay strata, the clay on the excavation surface is compacted by the cutterhead, and it is easy for a mud cake to gradually form on the cutterhead surface and the inner wall of the soil bin from the center of the cutterhead to the surrounding areas, thereby reducing the cutting efficiency of the cutterhead, prolonging the excavation time, increasing the torque of the cutterhead and the thrust of the shield, and also increasing the frequency of equipment failures. The existing shield machine cutterhead has a spiral blade shape, and the normal mud cleaning mechanism inserted into it can easily cause damage to the cutterhead, and it cannot fit into the spiral blade shape for processing, resulting in reduced mud cleaning efficiency.

[0003] In view of the above, we provide a shield machine cutter head surface attached mud cake removal device to solve the above problems. Summary of the Invention

[0004] In response to the above situation, the present invention provides a device for removing mud cake attached to the cutter head surface of a shield machine. The moving block and water outlet block designed in the device can be opened when inserted into the cutter head and closed when reaching a certain position, so that the moving block and water outlet block can be clamped on the cutter head and correspond to the shape of the cutter head.

[0005] A device for removing mud cake adhered to the cutter head surface of a shield machine comprises a fuselage, a drill bit mechanism is provided on one side of the fuselage, the drill bit mechanism comprises a drill bit and a cutter head, the cutter head is rotatably provided on one side of the drill head, an adjusting frame is rotatably provided on the surface of the drill head, a control frame is integrally provided on the lower surface of the adjusting frame, a lifting frame is slidably provided on the lower surface of the adjusting frame, a cleaning mechanism is provided on the lower surface of the lifting frame, the cleaning mechanism comprises a slider, a moving block and a water outlet block, the slider is slidably provided on the upper surface of the lifting frame, a moving block is rotatably provided on one side of the slider, and a water outlet block is rotatably provided on the other side of the slider, a cutter head is provided between the water outlet block and the moving block, a lifting groove is provided on the inner side wall of the fuselage, and the lifting frame is overlapped on the surface of the lifting groove.

[0006] The beneficial effects of the above technical solution are:

[0007] The moving block and water outlet block designed in this scheme can be opened when the cutter disc is inserted, and closed when reaching a certain position, so that the moving block and the water outlet block can be clamped on the cutter disc and correspond to the shape of the cutter disc. Since the cutter disc rotates, the cutter disc can drive the moving block and the water outlet block to move laterally and fit on the spiral structure to achieve the effect of clearing mud. When the moving block reaches a certain position, it can also make the lifting block move upward, and open the air outlet channel to blow the swept mud. The water outlet block can also be adapted to the width and rotated on the cutter disc to supply water, which facilitates the shedding of mud and reduces its friction. It can also reduce heat when the cutter disc rotates to achieve a cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The above and other technical contents, features and effects of the present invention are described below with reference to the attached Figures 1 to 10 It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0020] This embodiment provides a device for removing mud cake attached to the cutter head of a shield machine. Figure 1-10 As shown in the instruction manual, Figure 1 This is the three-dimensional structure diagram of this scheme, and the instruction manual is attached. Figure 2 Attached to the instruction manual Figure 1 Another perspective, the instruction manual is attached Figure 3 One side of the fuselage 1 was cut, and the instruction manual was attached. Figure 4 The fuselage 1 and the drill bit 2 are hidden and are attached to the instruction manual. Figure 5 The body 1 and the drill bit 2 are not shown at the beginning. Figure 6 The middle part of the slider 7 is cut, and the instructions are attached. Figure 7 Only the water outlet block 9 is partially cut, the instructions are attached. Figure 8 Show the location of the water delivery column 33, the instructions are attached Figure 9The shape of the lifting groove 25 is shown. The fuselage 1 of this scheme simply shows a ring. In fact, the fuselage 1 is very large and long, and one side of the fuselage 1 is a rotating drill bit 2. This scheme does not limit how one side of the fuselage 1 makes the drill bit 2 rotate stably. This technology already belongs to the existing technology. This scheme only provides one set of sliders 7, but in fact there are multiple sets, corresponding to the positions of the cutter disc 3. This scheme does not specifically set the corresponding shape, so it does not elaborate on how the fuselage 1 drives the drill bit 2 to rotate (which can be achieved through the motor gear structure). In fact, the drill bit 2 rotates on one side of the fuselage 1. This scheme provides an adjustment frame 4 based on this existing technology. The adjustment frame 4 can be rotatably set on one side of the drill bit 2, and a driving gear 35 (on the drill bit 2) is provided on one side of the adjustment frame 4. The inner ring of the drive gear 35 is provided with a tooth groove that meshes with the driving gear 35), and the driving gear 35 rotates to change the position of the adjusting frame 4, so that the adjusting frame 4 can adjust the position on the drill bit 2. Because the drill bit 2 has multiple cutter discs 3, it is necessary to adjust the position to clean the cutter discs 3 one by one. A servo motor is reserved on one side of the driving gear 35. The servo motor controls the driving gear 35 to rotate and can be self-locking. Therefore, the adjusting frame 4 can rotate to adjust the position (which does not conflict with this solution. This solution only requires the servo motor to be self-lockingly fixed to the drill bit 2). Therefore, when the drill bit 2 rotates on the fuselage 1, the adjusting frame 4 will rotate together. A corresponding lifting frame 6 that can move up and down is provided on the adjusting frame 4, and the lifting and lowering of the lifting frame 6 is driven by the lifting slot 10, as shown in the attached manual. Figure 1-3 The lifting groove 10 has two upper and lower rings, which are connected by an oblique groove, and the angles of the upper and lower rings are large. Therefore, when the drill bit 2 rotates (the adjusting frame 4 rotates together), the lifting frame 6 will move up and down on the adjusting frame 4, and will stay up and down for a long time, thus ensuring the normal operation of the slider 7. When the lifting frame 6 is in the lower position, it will reach the position of the cutter disc 3 and clean the spiral of the cutter disc 3. In order to increase the maneuverability of this solution, a moving block 8 and a water block 9 are set. The moving block 8 and the water block 9 are set left and right below the slider 7, and it is noted that the shapes of the moving block 8 and the water block 9 are roughly the same, and there is a gap between the two, which can just clamp the screw of the cutter disc 3. On the rotating blade, because the blade targeted by this solution is this kind of spiral blade (the cutter disc 3 can also be rotated, and the cutter disc 3 is in a spiral form, so the cutter disc 3 can also be rotated), it is very difficult to handle the mud attached to it, so a moving block 8 and a water outlet block 9 are designed. The next paragraph will introduce how to clamp on the spiral blade of the cutter disc 3. Since the cutter disc 3 itself will rotate, the clamped moving block 8 and the water outlet block 9 will be rotated. Because the slider 7 can slide at the bottom of the moving frame, and what rotates left and right on the slider 7 are the moving block 8 and the water outlet block 9, one side of the moving block 8 and the water outlet block 9 has a No. 3 spring 27, and the No. 3 spring 27 is a torsion spring that can be torsionally reset, and the instruction manual is attached. Figure 5 The three springs 27 are all in a torsion state, and the elastic force of the three springs 27 is large and not easy to twist. Therefore, when the cutter disc 3 rotates, the slider 7 will be driven to move as a whole through the moving block 8 (the default rotation direction of the cutter disc 3 makes the moving block 8 move). This is equivalent to the structure below the slider 7 moving laterally on the cutter disc 3 to achieve the effect of scraping off the soil, so as not to damage the cutter disc 3. When the cutter disc 3 drives the slider 7 to move as a whole in the direction of the main spring 13, the lifting block 11 will be moved upward and the rotating block 12 will be released at the same time. Let's first introduce how the lifting block 11 is lifted. The lifting block 11 is slidably set below the moving block 8 and cannot be rotated below the moving block 8. There is an inclined surface on the groove of the rotating cutter disc 3 of the drill bit 2 as shown in the attached manual. Figure 3 On the side of the label 11, when it reaches a certain position, the lifting block 11 will move upward. The upward movement of the lifting block 11 can make the gap on the release column 30 connected to the air outlet channel 29. It must be said here that an air supply pipe 31 is provided on one side of the moving block 8 (rotation center), and the air supply pipe 31 is connected to equipment such as an air compressor or an air blower and keeps delivering gas during the process, so it is displayed in the air. Since the moving block 8 can rotate, it is set at the rotation center so that it can deliver air to the rotating moving block 8, and after delivery, it reaches the inside of the moving block 8. The bottom of the moving block 8 is a release column 30, and the bottom of the release column 30 is plugged into the air inlet end of the air outlet channel 29 (the two are sealed and sliding). Only when the release column 30 moves downward (that is, the lifting block 11 moves upward, the channel will be opened) so that the notch of the release column 30 corresponds to the air inlet hole of the air inlet channel, so that it will be connected to achieve the effect of releasing gas, that is, the lifting block 11 acts as a lifting mechanism, which can make the cutter disc 3 spiral to the bottom without the need for the cutter disc 3 to rotate, and can act as a valve, automatically opening the channel to one side to discharge air, and the air pipe 31 keeps supplying gas to it (because it is in a sealed state when not released, the gas will be compressed when it enters), so once the channel is connected, the gas will be released quickly to achieve the effect of increasing the air impact force, and the No. 4 spring 28 can reset the lifting block 11. The introduction of the lifting block 11 needs to refer to the attached manual. Figure 6 For understanding, the above also introduces that the rotating block 12 will be released, because the rotating block 12 is rotatably arranged on the water outlet block 9, and both sides of the rotating block 12 have torsion springs for reset, as shown in the attached manual. Figure 6As shown, at this time, the rotating block 12 is hidden on one side of the water outlet block 9. At this time, the torsion spring has been twisted ninety degrees, that is, once released, it will rotate ninety degrees and be parallel to the cutter disc 3 (the release of the rotating block 12 depends on the disengagement bar 15, which is slidably arranged on one side of the water outlet block 9, and the bottom is inserted into the positioning block 14. The positioning block 14 has a hole for inserting the disengagement bar 15. There is a spring reset under the disengagement bar 15 to ensure that the disengagement bar 15 can be inserted into the positioning block 14. The positioning block 14 is arranged on one side of the rotating block 12 and is also an integrated design. In this way, it is only necessary to control the disengagement bar 15 to move upward, and the disengagement bar 15 moves upward relying on the lifting bar 24. The lifting bar 24 is vertically slidably arranged on the slider 7. Since the slider 7 needs to move in the direction of the main spring 13, it will drive the lifting bar 24 to move together, and one side of the lifting bar 24 is overlapped on the lifting groove 25. Therefore, during the lateral movement of the lifting bar 24, it will move upward to achieve the effect of controlling the upward movement of the disengagement bar 15, thereby achieving the effect of releasing the rotating block 12. Because the positioning block 14 is flat in design, it can be rotated again to make the disengagement bar 15 engage). The surface of the rotating block 12 is rotatably provided with a No. 1 column 16, and the other side of the No. 1 column 16 is slidably provided with a No. 2 column 17. The No. 1 column 16 and the No. 2 column 17 form a retractable rod, and the two are connected by an internal spring 18, as shown in the attached manual. Figure 10 As shown in the instruction manual, Figure 10 It is the instruction manual Figure 6 The perspective is just an additional picture for viewing the structure. At this time, the inner spring 18 is in its original length between the first column 16 and the second column 17. One end of the inner spring 18 is connected to the first column 16, and the other end is connected to the second column 17. The first column 16 and the second column 17 can slide between them. Both the first column 16 and the second column 17 are provided with a plurality of small holes for water outlet. At the position where the first column 16 and the rotating block 12 are connected, the first column 16 is provided with a corresponding water inlet notch, and the interior of the rotating block 12 is as shown in the attached manual. Figure 7 and 10 As shown, the conveyor belt can be connected to carry out rotary water delivery (the rotary air delivery and water delivery of this solution need to pay attention to sealing), the bottom of the water delivery belt 32 is inserted into the rotation center of the rotating block 12 for delivery, and the rotation center of any rotating block 12 then injects water between the No. 1 block and the No. 2 block through the gap of the No. 1 column 16. When one side of the water outlet block 9 is hidden, the telescopic rod composed of the No. 1 block and the No. 2 block maintains a certain length (because of the internal spring 18). What this solution needs to do is that when the rotating block 12 is released, the telescopic rod composed of the No. 1 column 16 and the No. 2 column 17 will first shorten, so that it can enter the spiral leaf of the cutter head 3. The shortening relies on the one-way bar 19 of this solution, refer to the attached manual. Figure 6The one-way strip 19 is rotatably mounted on the outlet block 9, and the center of rotation is at the top. Note that the rotation angle of the one-way strip 19 of this solution is limited, that is, the one-way strip 19 is anti-clockwise (the introduction of the one-way strip 19 requires viewing the instructions attached). Figure 6 , the one-way bar 19 angle rotation setting requires setting a corresponding rotation buckle on the axis to ensure the rotation angle. As for how to limit the rotation angle of the one-way bar 19, this solution does not introduce them one by one, because setting the corresponding rotation buckle is already very common in reality) for rotation, the rotation of the one-way bar 19 is less than 40 degrees (40 degrees is not the only determined value, but a specific value is given for easy understanding). Here we need to introduce the wide bandwidth of the one-way bar 19. The one-way bar 19 is on one side of the No. 1 column 16 and the No. 2 column 17 respectively. Note that it is one side, that is, the width of the No. 1 column 16 and the No. 2 column 17 is staggered with the one-way bar 19, as shown in the attached instruction manual Figure 6 As shown, at this time, the one-way bar 19 will not block the rotation of the first column 16 and the second column 17. If there is no structure above the second column 17, the structure composed of the first column 16 and the second column 17, the first column 16 can rotate freely on one side of the one-way bar 19. It happens that this solution has a wider piece above the second column 17, and the width of this piece cannot pass through the one-way bar 19. Therefore, when the rotating block 12 is released, the first column 16 and the second column 17 can only slide along the inner side of the one-way bar 19. Due to the setting of the one-way rotation angle of the one-way bar 19, the one-way bar 19 is a maximum of an oblique bar. At this time, the rotating block 12 continues to rotate (the rotation depends on the torsion spring at the rotation center of the rotating block 12. The torsion spring elastic force of the rotating block 12 is very large. Since the rotating block 12 blocks the torsion spring, it does not mean that the torsion spring of this solution is not The existence of) will continue to compress the wide band between the No. 1 column 16 and the No. 2 column 17, shortening the very short column. When the rotating block 12 rotates to about ninety degrees, it will be out of the squeezing of the one-way strip 19, releasing the No. 1 column 16 and the No. 2 column 17, which will extend under the action of the internal spring 18. The effect of this is to shrink the spiral blade entering the cutter disc 3 and automatically change the width on the cutter disc 3. Since the rotating block 12 can discharge liquid, the No. 1 column 16 and the No. 2 column 17 can also discharge water during the rotation process. The discharged water moistens the cutter disc 3, making it difficult for the soil and the cutter disc 3 to adhere. This is the release of the rotating block 12. How to release and retract the rotating block 12 will be introduced in the next paragraph. Here we also need to introduce how the water belt 32 carries out water. The top of the water belt 32 is connected to the water column 33. The slider 7 introduced above will move horizontally, as shown in the attached manual. Figure 6As shown, at this time, the water delivery column 33 is filled with water. Since the upper part of the slider 7 extends into the interior of the water delivery column 33 and is shaped like a piston, the liquid inside the water delivery column 33 will not be squeezed when it moves toward the left. Because a gap is set near the label 33, the gap piston cannot be sealed. Only by continuing to move toward the left can it be sealed. Because this gap is also the key to filling the water delivery column 33 with liquid again, refer to the attached manual. Figure 8 The water inlet of the water conveying belt 32 (the water conveying belt 32 is a soft belt) is on the left side of the conveying column. When it moves to the left, the liquid on the left side will be squeezed into the inside of the rotating block 12. The slider 7 will return to its initial position after reset and continue to squeeze out water. In order to ensure that there is water in the water conveying column 33 continuously, the water tank 34 needs to be very long and wide. Regardless of the position of the adjustment frame 4, water can be kept in the water conveying column 33. Corresponding nozzles need to be set on the surface of the No. 1 block and the No. 2 block to prevent the liquid from flowing out automatically and only squeeze out water;

[0021] This paragraph mainly introduces the control frame 5. Since the control frame 5 is extended and fixed below the adjustment frame 4, the control frame 5 is equivalent to being stationary, and the structure on the lifting frame 6 moves up and down. This scheme controls the recovery of the rotating block 12 in accordance with the up and down movement. First, the bifurcation strip 21 is introduced. The bifurcation strip 21 is integrally arranged below the control frame 5. A torsion block is slidingly provided on the bifurcation strip 21. A second spring 26 is provided on one side of the torsion block for reset. One side of the torsion block is spherical, and an inclined surface is extended on one side of the moving block 8 and the water outlet block 9, as shown in the attached manual. Figure 5 On one side of the numbers 8 and 9, when the lifting frame 6 moves upward, the torsion block will enter and squeeze to the bottom of the inclined surface, and when the lifting frame 6 returns downward, under the action of the torsion block, the moving block 8 and the water outlet block 9 will be opened, that is, the bottom will be opened. When they reach the vicinity of the cutter disc 3, they will be released due to the limited length of the inclined surface of the rotation center of the moving block 8 and the water outlet block 9 (the No. 3 spring 27 will rotate and reset during the release process. The No. 3 spring 27 is a torsion spring and is generally not easy to twist), thereby achieving the effect of clamping the spiral blades of the cutter disc 3. A round rod 22 is extended from the middle of the bifurcated strip 21. The position of the round rod 22 corresponds to one side of the positioning block 14, so the water outlet block 9 moves upward. During the movement, the positioning block 14 will be rotated 90 degrees and reset under the push of the round rod 22 (the positioning block 14 is relatively easy to squeeze). Before the positioning block 14 rotates, the maintaining bar 23 on one side of the round rod 22 will first rotate the one-way bar 19 (one side of the one-way bar 19 has a No. 1 spring 20 that can be rotated and reset, and the No. 1 spring 20 is a torsion spring), and then the one-way bar 19 will maintain a one-way rotation of 40 degrees. At this time, when the No. 1 column 16 and the No. 2 column 17 return to the inside, they will move along the outside of the one-way bar 19, and then cross the top of the one-way bar 19 (the internal spring 18 will be stretched at the top) to reach the initial position, as shown in the attached instruction manual. Figure 6 As shown, the function of the one-way bar 19 is to make the No. 1 column 16 slide and squeeze along the inside of the one-way bar 19 when it rotates out, and slide and stretch along the outside of the one-way bar 19 when the No. 1 column 16 rotates and resets. The width of the No. 1 column 16 will not contact the one-way bar 19, and only the top of the No. 2 bar contacts the one-way bar 19.
