DETAILED DESCRIPTION
[0050] In order to make the slag cleaning device suitable for slag cleaning operation of different media, the basic technical concept of the present application is to provide a slag cleaning mechanism with parallel pumping and slurry discharge and ring conveyor slag discharge. According to different accumulated slag conditions, different working modes can be matched to ensure smooth slag cleaning operation. The present application will be further described in detail in combination with the embodiments.
[0051] The specific embodiments of the mobile slag cleaning device provided by the present application are as follows:
[0052] The mobile slag cleaning device provided by the present application is as a whole as shown in Figures 1-4 , which includes a walking chassis 1 that can freely walk on the bottom of the tunnel. Specifically, the walking chassis 1 can be selected to be a chassis configured with a track walking mechanism 101, which is more suitable for uneven road surface compared with a tire walking mechanism. The walking chassis 1 is installed with a multi-mode slag cleaning mechanism, and the walking chassis 1 is equivalent to the carrying foundation of the multi-mode slag cleaning mechanism. The walking chassis 1 moves to drive the multi-mode slag cleaning mechanism to move forward and backward, thereby realizing that the multi-mode slag cleaning mechanism can freely and flexibly move to different positions when working.
[0053] The multi-mode slag cleaning mechanism most basically includes two slag cleaning modes. One is to continuously transport large slag stones by using a ring conveyor 3, and the other is to pump and send mud water (slag water) with high water content by using a slurry discharge pipe 7. Specifically, as shown in Figure 5 、 Figure 6 、 Figures 8-11As shown, the multi-mode slag removal mechanism includes a rack 2, a ring conveyor 3 and a slag box 4. The rack 2 is a groove structure with openings at both ends and the top end, which serves as the basis for installing the ring conveyor 3. Specifically, the rack 2 includes a bottom plate 201 and side plates 202 on both sides of the bottom plate 201, and the bottom plate 201 and the two side plates 202 together form a groove structure. The ring conveyor 3 is installed inside the groove structure. The opening at the front end of the groove structure is for the accumulated slag to enter, where the accumulated slag refers to the accumulated slag at the bottom of the tunnel, which may include a mixture of large slag stones, mud water, and silt during complex geological construction. The slag box 4 is used to store the accumulated slag, which has a set size of volume, and its specific shape can be square, cylindrical, etc., and the upper end can be open or closed. The opening at the rear end of the groove structure is in communication with the slag box 4. If the accumulated slag at the bottom of the tunnel is mainly large slag stones, the slag stones entering the groove structure can be sent to the inside of the slag box 4 by the ring conveyor 3. There is a set gap between the ring conveyor 3 and the bottom plate 201, which can allow the mixture of silt and mud water to flow, and under the blocking and guiding action of the two side plates 202, the mixture of silt and mud water can flow stably between the ring conveyor 3 and the bottom plate 201, that is, the ring conveyor 3, the bottom plate 201 and the two side plates 202 together form a flow channel for the flow of silt and mud water. In order to remove the silt and mud water entering the flow channel, the rack 2 is also provided with a discharge port in communication with the flow channel, and during construction, the discharge port can be connected to the slurry discharge pipe 7. After the slurry discharge pipe 7 is started, a negative pressure is formed in the flow channel, and then the silt and mud water can be removed. Preferably, the discharge port can be provided on the bottom plate 201, which is convenient for silt and mud water discharge. However, in other embodiments, the discharge port can also be provided on the side plate 202.
[0054] In order to facilitate the smooth entry of the accumulated slag during construction, in this embodiment, the rack 2, i.e. the opening at the front end of the groove structure, is also provided with a slag guide structure 11, which is used to guide the accumulated slag to enter the opening and can ensure the removal effect of the accumulated slag. Specifically, as shown in the drawings, Figure 1As shown, the slag guiding structure 11 is similar to the pusher structure, including a shovel plate 1101 and baffles 1102 located on both sides of the shovel plate 1101. To better collect and guide the accumulated slag, the opening formed by the baffles 1102 on both sides is larger than the opening at the front end of the frame 2. The shovel plate 1101 is also provided with a water passage for the slag-water mixture to flow through, which has a set size. At this point, the shovel plate 1101 also has a preliminary filtering and separation effect; larger pieces of slag cannot pass through the water passage and can be sent to the annular conveyor 3, while mud and water can pass through the water passage and enter the flow channel. Specifically, the shovel plate 1101 has a large, permeable hole in the center, and a grid 12 is installed at the hole. The grid holes of the grid 12 constitute the water passage. The grid 12 can be replaced as a whole; in the event of significant wear, the grid 12 can be directly replaced, resulting in low cost. Of course, in other embodiments, it is also possible to directly open through holes (circular, elongated, wavy) on the shovel plate 1101.
[0055] To further optimize the slag guiding effect of the slag guiding structure 11, a slag-removing wheel 13 is also installed on the shovel plate 1101. There are two slag-removing wheels 13, which rotate in opposite directions and can send the slag on the shovel plate 1101 to the ring conveyor 3.
[0056] The above describes an implementation method with better slag guiding and cleaning effects. In fact, in other implementation methods, the slag guiding structure 11 may not be provided. The accumulated slag can still enter the opening at the front end of the frame 2, and since the gap between the annular conveyor 3 and the bottom plate 201 is fixed, the slag and water will still enter the flow channel. If the accumulated slag at the bottom of the tunnel cannot be completely removed, it can be removed manually using shovels or other tools during construction.
[0057] To further expand the cleaning modes of the multi-mode cleaning mechanism, the annular conveyor 3 can be a reversible annular conveyor 3, specifically achieved by controlling the forward and reverse rotation of the drive element (motor or hydraulic motor) driving the annular conveyor 3. The rotation direction of the annular conveyor 3 conveying large pieces of slag to the slag box 4 is defined as positive. When the annular conveyor 3 rotates forward, large pieces of slag can be fed into the slag box 4 via the annular conveyor 3. When the annular conveyor 3 rotates in reverse, it also guides and pushes the slag and water into the flow channel. Based on this, the multi-mode cleaning mechanism can achieve the following four cleaning modes:
[0058] ①For example Figure 8 As shown, when the slag mainly consists of large pieces of slag, the ring conveyor 3 rotates forward, and the slag is fed into the slag box 4.
[0059] ②For example Figure 9As shown, in the case of mainly sludge water, the annular conveyor 3 reverses, and the sludge water can be sent into the flow-through passage. When the valve on the slurry discharge pipe 7 is opened, a negative pressure is formed inside the flow-through passage, and the sludge water is pumped into the sludge storage device in the tunnel, such as the sewage tank on the tunneling machine trailer.
[0060] ③As shown in the limit case, if there is too much sludge water, the slurry discharge pipe 7 cannot pump it in time, and the annular conveyor 3 can be reversed at high power to directly send the sludge water from the flow-through passage to the sludge box 4. Figure 10
[0061] ④As shown in another limit case, if the accumulated sludge is a mixture of large sludge stones and sludge water, the annular conveyor 3 is reversed, and the large sludge stones that cannot enter the flow-through passage are sent to the sludge box 4 by the annular conveyor 3, and the sludge water that enters the flow-through passage is pumped away by the slurry discharge pipe 7. Figure 11
[0062] In order to realize the above-mentioned several sludge cleaning modes, preferably, the annular conveyor 3 can adopt a belt conveyor, and the belt conveyor is preferably a belt conveyor, and a plurality of push plates 302 are arranged on the conveying belt 301 of the belt conveyor, the push plates 302 are arranged at intervals along the conveying direction of the conveying belt 301, and the interval between the adjacent two push plates 302 and the height of the push plate 302 are not limited in this embodiment, and can be flexibly set according to the specific conveying requirements. When the annular conveyor 3 is reversed, the push plate 302 also has the effect of pushing the sludge water to flow. Of course, it should be noted that in other embodiments, a scraper conveyor can also be used as the annular conveyor 3.
[0063] In order to meet the continuous conveying of the sludge stones, in this embodiment, as shown in the figure, a sludge discharge port for connecting the pumping pipe is arranged at the lower position of the sludge box 4. During the sludge cleaning operation, the sludge stones, sludge water and the like sent into the sludge box 4 can be pumped away through the pumping pipe. Among them, the caliber of the sludge discharge port and the pumping pipe should meet the sludge stone conveying. Figures 1-6
[0064] Further, the slag box 4 is provided with a spraying device 5 above the rear side of the ring conveyor 3, the spraying device 5 has water spraying openings facing the interior of the slag box 4 and a water pipe interface for connecting a water supply pipe 6. When performing the slag cleaning operation, the spraying device 5 can be opened to spray water into the interior of the slag box 4. On one hand, the slag stones discharged from the ring conveyor 3 to the slag box 4 can be quickly dropped into the slag box 4, on the other hand, since the viscosity of water is greater than that of air, the slag stones in the slag box 4 can also be quickly sucked out. Specifically, the spraying device 5 can be a spraying pipe as shown in the figure, and a spray head can be installed at the water spraying opening of the spraying pipe. Alternatively, the spraying device 5 can also be a spraying tank, a spraying box or the like, and the spraying opening can also be a long strip.
[0065] Further, the spraying device 5 is installed on the slag box 4 through a rotatable rotating structure 10, and the rotating axis extends horizontally and perpendicularly to the conveying direction of the ring conveyor 3. The rotating structure 10 can be a manually adjusted rotating frame, and when performing the slag cleaning operation, the spraying device 5 can be rotated by adjusting the rotating structure 10, so as to adjust the orientation direction of the water spraying opening. In this way, by using the fluidity of water, it can be ensured that the slag stones located at different positions in the slag box 4 can be sent to the bottom of the slag box 4 and sucked out by the slag suction pipe 8. In addition, the spraying device 5 can also flush the inner wall of the slag box 4 to avoid the adhesion of mud slag on the inner wall of the slag box 4.
[0066] Further, the slag box 4 is provided with a liquid level detection device for detecting the liquid level height of the slag box 4, specifically, the liquid level detection device can be a liquid level sensor 9 or a range finder based on sound or light ranging principle. When performing the slag cleaning operation, the spraying device 5 can be controlled to start and stop according to the ranging signal of the liquid level sensor 9. There are various ways to control the spraying device 5 to start and stop, for the spraying pipe type spraying device 5, the valve on the water supply pipe 6 can be directly controlled to close, for the water spraying box or spraying tank type spraying device 5, the water spraying opening can be controlled to close, and the specific control principle is not described in detail as prior art. By setting an automatic control system, it can be ensured that the interior of the slag box 4 maintains a certain water level, avoiding water shortage or water overflow. Of course, in other embodiments, the interior of the slag box 4 can also be manually observed, and the spraying device 5 can be manually controlled to start and stop.
[0067] In addition, when the multi-mode slag cleaning mechanism is installed, the rear end of the rack 2 is hingedly connected to the slag box 4, and the hinge axis extends horizontally and transversely (perpendicularly to the conveying direction of the ring conveyor 3), so as to realize the up-down pitching swing of the rack 2. In addition, the multi-mode slag cleaning mechanism is also provided with a telescopic drive 14 for driving the pitching swing of the rack 2. Figure 3 and Figure 7As shown, the telescopic drive 14 is hingedly connected at one end to the rack 2 and at the other end to the carrying base, i.e. the travelling chassis 1, which carries the multi-mode slag cleaning mechanism. Specifically, the telescopic drive 14 can be an electric push rod, a hydraulic cylinder, a pneumatic cylinder, etc. In this way, the height of the front end of the rack 2 can be flexibly adjusted according to different slag accumulation heights, so as to ensure the slag cleaning effect and avoid the front end of the rack 2 from scraping the ground.
[0068] It is emphasized here that the present embodiment gives a case where the multi-mode slag cleaning mechanism is installed on the travelling chassis 1. In other embodiments, the multi-mode slag cleaning device can be integrated on a heading machine, for example, on the main beam or connecting bridge or trailer of a TBM, and the corresponding carrying bases are the main beam, connecting bridge or trailer, respectively. The other end of the telescopic drive 14 can be hingedly connected to the corresponding carrying base.
[0069] It is also to be noted that the discharge pipe 7 is preferably made of steel pipe. In the case where the discharge pipe 7 is connected, a flexible expansion joint can be arranged at the part of the discharge pipe 7 located in front of the slag tank 4, so as to ensure that the rack 2 can be smoothly swung.
[0070] In order to facilitate the connection of the discharge pipe 7, as shown in Figures 8-11 The rack 2 is provided with an adapter 15 at the position of the discharge port. In fact, the discharge port is connected to the discharge pipe 7 through the adapter 15, so that the position of the connected discharge pipe 7 can be adjusted according to the actual situation. Specifically, a quick connector can be installed on the adapter 15. Of course, in other embodiments, the discharge pipe 7 can also be directly connected to the discharge port.
[0071] In addition, the slag tank 4 is internally provided with a slag pipe installation channel through which the discharge pipe 7 passes from front to back. As shown in Figure 6 From the perspective of the perspective, the discharge pipe 7 can directly pass through the slag pipe installation channel, which is convenient and efficient, and can also save the space occupied by the discharge pipe 7. The slag tank 4 also supports the discharge pipe 7. Specifically, a partition can be arranged inside the slag tank 4, and through holes are formed at the front and back ends to form the slag pipe installation channel.
[0072] When the annular conveyor 3 is arranged, an annular conveyor 3 including an inclined section and a horizontal section can be selected, and the horizontal section is located at the rear end. Compared with the annular conveyor 3 with all inclined sections, the direction of the slag stones discharged from the annular conveyor 3 is horizontal, which is more likely to fall into the slag tank 4 in a parabolic trajectory.
