Description

Technical Field

[0001] The invention relates to the technical field of slag conveying, and in particular to slag conveying equipment for the tail of a TBM tunneling machine. Background Art

[0002] In coal mine tunnel excavation operations, tunnel boring machines form tunnels by cutting and digging underground rocks. This process produces a large amount of rock slag that needs to be recycled. In the prior art, the rock slag produced by the excavation process is guided to a conveyor belt, and the conveyor belt is used to transport the rock slag from the excavation site to the far end. After transportation, the rock slag is screened by an additional screening device, and the rock slag is recovered and backfilled.

[0003] During use, the transported rock slag has a certain temperature due to the friction and crushing of the rock by the cutter during excavation. At the same time, the accumulated rock slag is mixed with a large amount of rock slag of different sizes, and it is necessary to add auxiliary cooling and screening equipment, which occupies a large space and has poor use effect.

[0004] In view of the above, we provide a rock slag conveying equipment for the tail of a TBM tunneling machine to solve the above problems. Summary of the invention

[0005] In view of the above situation, the present invention provides a rock slag conveying equipment for the tail of a TBM tunneling machine. The equipment can shake the rock slag multiple times by rotating and conveying the rock slag. During the shaking process, the rock slag can continuously change its position, so that the rotating column below can spray liquid onto the rock blocks to cool down the rock blocks. The screening width can also be continuously changed during the shaking process.

[0006] A rock slag conveying device for the tail of a TBM tunneling machine comprises a shell, a rotating conveying mechanism is arranged inside the shell, the rotating conveying mechanism comprises a conveying disc, a conveying block and a conveying frame, the conveying disc is rotatably arranged inside the shell, the conveying block is rotatably arranged on the edge of the conveying disc, the conveying frame is slidably arranged on the surface of the conveying block, a return spring is arranged between the conveying block and the conveying frame, a rotating column is arranged in the middle of the conveying frame, a screening rod is slidably arranged on the upper surface of the conveying frame, a positioning mechanism is arranged inside the shell, the positioning mechanism comprises an upper frame and a lower frame, a force storage block is integrally arranged on the lower surface of the lower frame, a rotating disc is rotatably arranged on the lower surface of the conveying frame, and the screening rod is overlapped on the surface of the rotating disc.

[0007] The above technical solution has the following beneficial effects:

[0008] This solution can shake the rock slag multiple times by rotating the rock slag for conveying it. During the shaking process, the rock slag can continuously change its position, so that the rotating column below can spray liquid onto the rock block to cool it down. During the shaking process, the screening width can also be continuously changed. During the continuous shaking process, different screening rods can be switched in order to discharge air, thereby achieving the effect of multi-directional air discharge. The rock slag can be screened by blowing air in different directions, and the surface of the rock slag can be cooled during the blowing process. In conjunction with the rotating column to discharge water, a double cooling effect can be achieved. The conveying block can automatically flip and automatically restore when it reaches a specific position, and the conveying block can also be fixed in position by being put on and taken off the conveying disc to facilitate its stable rotation.

DETAILED DESCRIPTION

[0020] The above and other technical contents, features and effects of the present invention are described in detail 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.

[0021] This embodiment provides a rock slag conveying device for the tail of a TBM tunneling machine, as shown in the attached Figure 1-10 As shown in the instruction manual, Figure 1 The overall schematic diagram shows that the housing 1 is taken from the tail of the tunnel boring machine. Figure 1 The transmission mechanism is shown in Figure 1 The three conveyor belts are named upper, middle and lower according to their upper and lower positions. The upper conveyor belt is used for moving the slag to the right, falling onto the conveyor frame 4, and then being transported to the middle conveyor belt through the rotating conveyor disc 2. The lower conveyor belt is responsible for catching the slag removed during the rotating process of the conveyor disc 2 to achieve the screening effect. Figure 2 The shell 1 is removed, showing that the structure of this solution is suspended, but in fact it is not. For example, the upper frame 7 and the lower frame 8 are fixedly arranged on the shell 1, and corresponding limit buckles are arranged on the upper frame 7 and the lower frame 8 to realize the stable rotation of the conveyor plate 2. These limit buckles are not shown, so it can be seen from the attached manual that the upper frame 7 and the lower frame 8 are fixedly arranged on the shell 1. Figure 2 At first glance, this solution seems to be suspended in the air. Figure 1 These structures are gradually displayed under the premise of Figure 3 See the bottom structure of the conveyor tray 2, the instructions are attached Figure 4 It is a separate display of the conveying block 3 and the conveying frame 4, and the instruction manual is attached. Figure 5 And the instruction manual Figure 4 It's just a difference in perspective. Figure 6 Cut along the middle of the conveying block 3, the instructions are attached Figure 8 And the instruction manual Figure 6The cutting directions of the two drawings are different, and the cutting directions of the two drawings are vertical, so that the front and rear left and right angles of the conveyor frame 4 are displayed. Fig. 9 The conveyor frame 4 is hidden, and the instruction manual is attached. Fig.10 The middle part of the rotating disk 16 is cut, as shown in the attached manual. Figure 2 The conveyor disc 2 of the scheme shown in the figure rotates counterclockwise, and the conveyor frame 4 on the upper left rotates to the lower right to complete unloading. The unloading of this scheme is through the flip block 37 on one side of No. 2 plus. The flip block 37 makes the bottom of the conveyor frame 4 enter the edge to form extrusion, and the conveyor frame 4 is rotated during the extrusion process. Since there is rock slag above the conveyor frame 4, a seesaw-like structure is formed between the conveyor frame 4 and the conveyor block 3, which enables this structure to rotate on the conveyor disc 2. When the scheme is unloaded, the center of gravity of the structure formed by the conveyor frame 4 and the conveyor block 3 (first viewed as a whole) is at the bottom, that is, the conveyor frame 4 is in a vertical state under normal conditions, ensuring stable transportation of the conveyor disc 2 during cyclic operation, and the limit between the upper frame 7 and the lower frame 8 makes the conveyor frame 4 stable in a vertical state when passing through the force storage block 9, and when it reaches the lower right, it can be rotated and unloaded at the top block of the flip block 37 (see the attached manual). Figure 2 The rotation space of the conveying block 3 is small. In fact, the rotation space of the conveying block 3 is huge, so it is only necessary to widen the opening width of one side of the conveying block 3 to meet the requirements of the conveying frame 4 rotating 360 degrees for unloading). Figure 2 A notch is reserved between the upper frame 7 and the lower frame 8 at the lower right position to allow the conveying block 3 to rotate. The flip block 37 has two fixing methods. First, it can be fixed on one side of the lower frame 8, as shown in the attached manual. Figure 2 As shown, the second is to extend downward and be fixed to the shell body 1, so that the flip block 37 is stable, the conveying block 3 is rotatably set on the conveying disc 2, and the conveying frame 4 can slide on the conveying block 3, and a return spring 38 is arranged between the conveying block 3 and the conveying frame 4. The return spring 38 is difficult to squeeze, so the conveying frame 4 can only be driven to move downward by the force storage block 9. The main structure of this scheme to realize the function is the force storage block 9, which is below the lower frame 8 and has multiple force storage blocks 9. The force storage block 9 has an inclined surface, and there are two cylinders at the bottom of the conveying frame 4. The first cylinder is a connecting pipe 35, and the connecting pipe 35 is responsible for connecting to the inside, and there is also a cylinder above the connecting pipe 35, as shown in the attached manual Figure 3As shown, the top of the connecting pipe 35 can just reach the inclined surface on one side of the force storage block 9, so the force storage block 9 can make the conveying frame 4 move downward on the conveying block 3, so that the reset spring 38 is squeezed to store force, and the force storage block 9 of the present scheme and the cylinder on the side of the conveying frame 4 will eventually break away from contact, and it is a cliff-like break away from contact. In this way, since the reset spring 38 is squeezed and the contact is broken away from the cliff, the reset spring 38 stores force and then releases it to achieve the effect of rapid upward bounce of the conveying frame 4. The present scheme realizes other functions based on this effect, that is, the force storage block 9 is an indispensable part of the present scheme, especially the shape of the force storage block 9, here First, the effect of the power storage spring setting of this scheme is introduced. Since the basis of the design of this scheme is screening and cooling, the upward spring can make the rock slag bounce upward, so that the small rock slag can be conveniently blown out to the outside by the screening rod 6 after it bounces, and the screening is completed. Secondly, the original blocking is changed when it bounces upward (breaking the original state of the rock slag and making it fall to the bottom again), so that the screening rod 6 can also blow air during the falling of large rock slag to achieve the effect of cooling. The blowing of the screening rod 6 has two effects: the first is to blow away small rock slag, and the second is to blow it to the surface of large rock debris for cooling. This is the reason why the power storage block 9 is designed in this scheme;

[0022] The previous paragraph introduced that the force storage block 9 enables the conveying frame 4 to slide on the conveying block 3, and the conveying block 3 is clamped by the upper frame 7 and the lower frame 8 so that it cannot rotate, so that the conveying frame 4 can stably slide on the conveying block 3. This paragraph introduces the effect brought by the force storage block 9. First, in the process of the conveying frame 4 moving downward (pulled downward by the force storage block 9), the force storage ring 22 can be rotated. The force storage ring 22 is rotatably arranged inside the conveying frame 4, and an internal spring 23 is arranged between the conveying frame 4 and the conveying frame 4. The internal spring 23 is a torsion spring that can be torsionally reset. Since the conveying frame 4 moves downward and the chamfering block 25 does not move, the force storage ring 22 has to rotate, and the force storage ring 22 is provided with a spiral groove 24 that cooperates with the chamfering block 25, so that the force storage ring 22 rotates continuously when the conveying frame 4 moves downward until the chamfering block 25 reaches the outlet of the spiral groove 24, as shown in the attached manual Fig. 9 As shown, there is an outlet at the top of the spiral groove 24, and the surface of the outlet is provided with a downward chamfer, and the chamfer block 25 can only rotate upward (as shown in the attached manual Figure 6As shown, a bar extending from the conveying block 3 is provided below the chamfering block 25 so that the chamfering block 25 cannot rotate downward, so that when the chamfering block 25 reaches the top of the spiral groove 24, the force storage column will be released, so that the force storage column will rotate rapidly under the need of the internal spring 23, and the chamfering block 25 can rotate through the lower inclined surface during the downward reset process, and can smoothly reach the initial position. Although the chamfering block 25 is rotatably arranged on one side of the conveying block 3, a torsion spring needs to be provided on one side so that the chamfering block 25 can maintain a horizontal state and can also be rotated and reset). In this way, the chamfering block 25 25 can come and go freely, and can make the power storage ring 22 rotate and store power, reach the top to release, and can drive the rotating column 5 to rotate during the release process. The rotating column 5 is rotatably arranged inside the conveying frame 4, and a bearing needs to be arranged between the two to ensure that the rotating column 5 rotates stably, and the limited rotating column 5 rotates. The power storage ring 22 rotates to make the rotating column 5 rotate, because an insertion block 26 is slidably arranged on the lower surface of the power storage ring 22, and the lower part of the insertion block 26 is inserted into the surface of the rotating column 5, so that the insertion block 26 and the rotating column 5 form a one-way rotation mechanism, as shown in the attached manual Figure 5 There is a plug 26 above the rotating column 5, which is compatible with the insert block 26. Fig. 9As shown, the rotating column 5 also shows this groove, so that when the conveying frame 4 moves downward to the maximum distance, it can release the storage ring 22 to rotate, and the rotation of the storage ring 22 drives the rotating column 5 to rotate, and the rotating column 5 can drive the rotation and give it a certain potential energy, and the insertion block 26 does not affect the rotation of the rotating column 5. The rotation of the rotating column 5 can make the upper nozzle discharge liquid. There is a nozzle above the rotating column 5. The rotation of the rotating column 5 can make the nozzle rotate to achieve a large range of injection, and the rotation time of the rotating column 5 corresponds to the reset time of the conveying frame 4, so that the rock slag that bounces upward can spray liquid to achieve a cooling effect, and the rock slag that is broken up in the previous paragraph is combined with the liquid sprayed from the rotating column 5 and more rock slag. In order to enable the smaller rock slag to be blown out by this scheme and to switch the angle in an orderly manner, a screening rod 6 is designed in this scheme. The screening rod 6 is slidably arranged on the top of the conveying disc 2. The position of the screening rod 6 is controlled by the rotating disc 16 at the bottom. A notch is provided on the upper surface of the rotating disc 16 to just plug in the screening rod 6. However, when the rotating disc 16 rotates, the screening rod 6 can move outward, and the screening rod 6 can place the rock on the top. The conveying frame 4 of this scheme does not necessarily have four screening rods 6. The number of screening rods 6 can be designed according to the actual size of the rock blocks required. The distance between every two adjacent screening rods 6 is the size of the screened rock blocks. The rotating disc 16 is rotated by relying on the rotating groove 17. The middle part of the rotating disc 16 A rotating groove 17 is provided in the device, and the rotating groove 17 is an oblique groove, and a corresponding block 18 corresponding to the entry position of the rotating groove 17 is provided above the conveying block 3, so that the corresponding block 18 can enter the rotating groove 17, driving the rotating disk 16 to rotate, and the rotation of the rotating disk 16 can make multiple screening rods 6 spread outward, so as to achieve the effect of expanding the screening hole, and can be linked with the upward reset of the conveying frame 4 to achieve the effect of changing the size of the screening hole and breaking up the rock, and a hole facing the middle part of the conveying frame 4 is provided inside the screening rod 6, so that the screening rod 6 can spray gas to screen smaller rocks (blown onto the conveyor belt below), and in order to enable this scheme to switch the direction of the gas spray, a control circle 12 is designed, and the rotation of the control circle 12 is arranged It is placed at the bottom of the conveying frame 4. The rotation of the control circle 12 relies on the driving circle 21. The driving circle 21 is rotatably arranged on the conveying frame 4. Here is an introduction to the moving trajectory of the rotating disk 16. After the rotating disk 16 is away from the corresponding block 18, it will be reset under the action of the No. 1 spring 19. The No. 1 spring 19 is an arc spring, which can make the rotating disk 16 rotate and reset. In this way, the periodic law of the rotating disk 16 is to rotate first and then rotate and reset, which is equivalent to a swinging mechanism. In order to make this swinging mechanism convey to the control circle 12 so that the control circle 12 rotates all the time, a driving circle 21 is designed. A driving block 20 is arranged on one side of the rotating disk 16. A spring is used on one side of the driving block 20 to make the driving block 20 contact the driving circle 21.The driving ring 21 has a one-way structure similar to the insertion block 26, so that the driving ring 21 becomes a continuous rotation, that is, the rotating disk 16 drives the driving ring 21 to rotate back and forth, and the driving ring 21 can rotate by meshing the control ring 12, and the control ring 12 is provided with a support block 13, which is an arc-shaped block with a range of 90 degrees and chamfers on both sides. The support block 13 can only lift up one blocking rod 14, and the lifted blocking rod 14 represents that only one through pipe 11 is connected to the conveying pipe 10 (as shown in the attached manual, Figure 7 As shown), in this way, only one set of through-tubes 11 delivers gas to the screening rod 6, and as the control circle 12 rotates, multiple sets of screening rods 6 switch the jet in order to achieve the effect of jetting gas at different angles, blowing off small rocks at different angles, completing the screening action, and adapting to cooling at multiple angles. A second spring 15 is provided below the blocking rod 14, which can automatically reset the blocking rod 14 upward (as shown in the attached manual). Figure 7 As shown), the delivery pipe 10 penetrates into the interior of the delivery rack 4 and continues to supply gas to two, the first is the delivery pipe 10 introduced above (a section of the penetration pipe 11 is a soft pipe, which is convenient for the selection rod 6 to move), and the second is the corresponding channel 31 inserted into the delivery pipe 10. The corresponding channel 31 can blow air to the edge of the lifting plate 27. The lifting plate 27 is slidably arranged above the rotating column 5 and is sealed and slid with the corresponding channel 31. The bottom of the lifting plate 27 is overlapped with the lifting groove 28, and the lifting groove 28 is opened in the interior of the delivery rack 4. The lifting groove 28 is an annular groove with the highest and lowest points, and the rotating column 5 drives the lifting plate 27 to rotate so that the lifting plate 27 moves up and down. This scheme uses the lifting plate 27 to move up and down to control the switching of the channel, such as channel 29. Channel 29 is two upper and lower notches, which are connected close to the center (attached to the joint instruction manual Figure 7 and 8 understanding), the shape is similar to the sideways U-shape, except that the connected Figure 7 Blocked, Figure 8 As shown in FIG. 1 , channel No. 2 30 is an L-shaped channel. Figure 731 and 30. The lifting plate 27 moves upward to solve the problem of misalignment of the second channel 30 and change it to correspond to the first channel 29, so that the middle air outlet is switched to the side air blowing, so as to achieve the effect of air outlet at different angles. The fan can be set at the tail of the conveying pipe 10 to achieve the air outlet. This scheme also requires water, which is transported through the water pipe 33, corresponding to the water outlet of the rotating column 5. The bottom of the rotating column 5 is plugged with a connecting pipe 35, and the two are rotatably plugged, which does not affect the rotation of the rotating column 5. In the middle of the conveying plate 2, an arc frame 32 is provided and a spring is provided on the surface. The arc frame 32 is not suspended, but is also extended and fixed on the shell 1. A contact block 34 is rotatably provided on the arc frame 32, and a water pipe 33 is slidably provided on the contact block 34 (as shown in the attached manual Figure 3As shown, the water pipe 33 can wait for the connecting pipe 35 to come over. The connecting pipe 35 and the water pipe 33 need to be provided with corresponding magnets (preferably strong magnets) at the contact position to attract each other to form a channel connection. The water pipe 33 is a hose except for the position where it is connected to the connecting pipe 35, and a sliding distance is set between the water pipe 33 and the contact block 34 (the purpose of this design is because the conveying frame 4 will change its position vertically, and the purpose of setting such a distance is to adapt to the change of position of the conveying frame 4 so that the two pipes can be connected at this time). As the conveying disc 2 rotates until it leaves the range of the arc frame 32 and returns to the initial position to wait for the next connecting pipe 35, the tail end of the water pipe 33 needs to be connected to the inside of the water tank and installed with equipment such as a water pump (this operation is in the prior art and is not carefully examined).
