Description

Technical Field

[0001] This invention relates to the field of crushed stone transfer device technology, and in particular to a crushed stone transfer device and method for tunnels. Background Technology

[0002] Tunnel engineering refers to structures built underground, underwater, or within mountains to lay railways or construct highways for motor vehicles. Based on their location, they can be divided into three main categories: mountain tunnel engineering, underwater tunnel engineering, and urban tunnel engineering. Mountain tunnel engineering involves tunnels that pass under mountains or hills to shorten distances and avoid steep gradients; underwater tunnel engineering involves tunnels that pass under rivers or straits to cross them; and urban tunnel engineering involves tunnels that pass underground within cities to accommodate railways passing through large cities. Among these three types, mountain tunnel engineering is the most common.

[0003] It should be noted that during tunnel construction, the excavation of tunnel boring machines generates a large amount of gravel, which needs to be continuously transported out of the tunnel using gravel transport vehicles to ensure the continuity of tunnel construction. However, the process of loading gravel onto transport vehicles generates a large amount of dust during both loading and transportation. Since the space inside the tunnel is confined, this large amount of dust not only affects the tunnel environment but also poses a health hazard to workers. Furthermore, the bumpy roads during gravel transport cause continuous dust generation, resulting in environmental pollution along the route. Unrestrained gravel also tends to fall during transport, easily puncturing the tires of the transport vehicles. Therefore, existing gravel transport vehicles suffer from these numerous problems. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for transferring crushed stone in a tunnel, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A crushed stone transfer device for tunnels includes a truck bed and a frame, wherein the truck bed is mounted on the frame and a discharge plate is rotatably mounted on the truck bed;

[0007] It also includes a non-powered dust suppression mechanism, which is installed on the truck bed and is used to spray and suppress dust from the gravel inside the truck bed. The non-powered dust suppression mechanism includes a water tank, which is installed on the bottom side of the truck bed. A water outlet pipe is installed on one side of the water tank, and a dust suppression water pipe is connected to the water outlet pipe. Multiple water spray heads for spraying water are installed on the dust suppression water pipe. A limiting pressure frame is movably installed inside the water tank, and a pressure plate is installed on the bottom side of the limiting pressure frame. A load-bearing filter plate is provided inside the truck bed, and two pressure rods are installed on the bottom side of the load-bearing filter plate. Both pressure rods are movably installed on the truck bed. An arc-shaped drive plate is slidably installed on the top side of the water tank. The arc-shaped drive plate is used to lock the limiting pressure frame. A linkage rod is rotatably installed between the arc-shaped drive plate and one of the pressure rods.

[0008] The truck bed is equipped with an automatic blocking mechanism, which is used to automatically close the truck bed to prevent the loading of gravel; the automatic blocking mechanism includes two tilting blocking plates, both of which are rotatably mounted on the truck bed, and the two tilting blocking plates tilt to automatically close the truck bed;

[0009] It also includes a synchronous recovery filtration mechanism, which is installed on the non-powered dust suppression mechanism. The synchronous recovery filtration mechanism is used to synchronously filter and recover the wastewater discharged by the non-powered dust suppression mechanism. The synchronous recovery filtration mechanism includes a water collection and recovery pipe, which is installed on the bottom side of the load-bearing filter plate. The bottom side of the water collection and recovery pipe is inserted into the water storage tank and is rotatably mounted with a filter cover for filtering water.

[0010] Furthermore, in a preferred embodiment of the present invention, the non-powered dust suppression mechanism further includes a transfer box, which is installed between the water outlet pipe and the dust suppression water pipe;

[0011] The transfer box is equipped with a connecting frame. A sealing water-blocking plate for sealing the connecting frame is movably installed on one side of the transfer box. The sealing water-blocking plate and the arc-shaped drive plate are equipped with mutually adsorbing magnets.

[0012] Furthermore, in a preferred embodiment of the present invention, a transverse sliding groove is provided on the top side of the water storage tank, and the arc-shaped drive plate is slidably installed in the transverse sliding groove;

[0013] A downward pressure spring is installed on the top side of the water storage tank, and the top end of the downward pressure spring is installed on the limiting downward pressure frame. Two auxiliary wheels are rotatably installed on both sides of the water storage tank.

[0014] Furthermore, in a preferred embodiment of the present invention, two return springs are installed on the bottom side of the truck bed, and the two return springs are respectively installed on the two downward pressure rods.

[0015] Furthermore, in a preferred embodiment of the present invention, mounting brackets are rotatably mounted on both sides of the overturning blocking plate, and both mounting brackets are mounted on the truck bed;

[0016] Both mounting brackets are rotatably mounted with a flip shaft, which is respectively mounted on both sides of the flip blocking plate. A drive gear is mounted on each of the two flip shafts near the water storage tank. A drive rack is meshed on each of the two drive gears. A push rod for synchronous movement is installed between the two drive racks. When the arc-shaped drive plate moves, it pushes the push rod to move, thereby driving the two drive racks to move synchronously.

[0017] Furthermore, in a preferred embodiment of the present invention, two lifting slots are provided on one side of the truck bed, and a lifting rod is slidably installed in the lifting slot, the lifting rod being mounted on the drive rack frame;

[0018] A return spring is installed on the lifting rod, and the other end of the return spring is installed on the inner wall of the lifting groove.

[0019] Furthermore, in a preferred embodiment of the present invention, the synchronous recycling filtration mechanism further includes an L-shaped cleaning brush, which is installed inside the water collection and recycling pipe, and the filter cover is rotated and cleaned by the L-shaped cleaning brush;

[0020] An insertion hole is provided on the top side of the water storage tank, the water collection and recovery pipe moves within the insertion hole, and a water distribution baffle is installed inside the water storage tank.

[0021] Furthermore, in a preferred embodiment of the present invention, a rotating hole is provided on the bottom side of the filter cover, and a support rod is installed on the bottom inner wall of the water storage tank, with the top end of the support rod passing through the rotating hole;

[0022] The support rod has a threaded groove, and a driven arc-shaped block is installed on the inner wall of the rotating hole. The driven arc-shaped block is located in the threaded groove.

[0023] Furthermore, in a preferred embodiment of the present invention, a rotating groove is provided on the bottom side of the water collection and recovery pipe, and a rotating ring is rotatably installed in the rotating groove, the rotating ring being installed on the filter cover.

[0024] A method for transferring crushed rock inside a tunnel, based on the aforementioned crushed rock transfer device, includes the following steps:

[0025] S1. When the crushed stone is loaded into the truck bed, causing the load-bearing filter plate to move downward under force, it drives the two lower pressure rods to move. The movement of the lower pressure rods drives the arc-shaped drive plate to move through the linkage rod, causing the arc-shaped drive plate to disengage from the limiting lower pressure frame. Under the pull force of the lower pressure spring, the limiting lower pressure frame drives the pressure plate to move downward. The pressure plate applies pressure to the water in the water storage tank, causing the water in the water storage tank to enter the transfer box through the water outlet pipe, and then enter the dust suppression water pipe through the transfer box. Finally, it is sprayed into the truck bed through multiple water nozzles to suppress dust in the crushed stone in the truck bed.

[0026] S2. When the load-bearing filter plate is loaded to its maximum weight, the arc-shaped drive plate pushes the closed water-blocking plate to move, thereby causing the closed water-blocking plate to close the connecting frame and automatically cut off the water supply.

[0027] S3. The arc-shaped drive plate moves, squeezing and pushing the round rod to move, so that the pushing round rod synchronously drives the two drive racks to move synchronously. The movement of the two drive racks drives the two drive gears to rotate, so that the two drive gears drive the two tilting blocking plates to rotate through the two tilting shafts, thus closing the truck bed.

[0028] S4. The sprayed water is filtered by the load-bearing filter plate and enters the filter cover through the water collection and recovery pipe. After being filtered by the filter cover, it enters the water storage tank and is stored. The load-bearing filter plate moves down, causing the water collection and recovery pipe to move in the insertion hole. The water collection and recovery pipe moves on the support rod through the rotating hole. The water collection and recovery pipe moves in the threaded groove through the driven arc block, causing the filter cover to rotate, so that the filter cover is cleaned by the L-shaped cleaning brush.

[0029] The beneficial effects of the tunnel crushed stone transfer device and method proposed in this invention are:

[0030] In this invention, by setting up a non-powered dust suppression mechanism, when the crushed stone is loaded into the truck bed, the load-bearing filter plate is forced to move downward, which drives the two lower pressure rods to move. The movement of the lower pressure rods drives the arc-shaped drive plate to move through the linkage rod, causing the arc-shaped drive plate to disengage from the limiting lower pressure frame. At this time, under the pull force of the lower pressure spring, the limiting lower pressure frame drives the pressure plate to move downward. The pressure plate applies pressure to the water in the water storage tank, causing the water in the water storage tank to enter the transfer box through the water outlet pipe, and then enter the dust suppression water pipe through the transfer box. Then, it is sprayed into the truck bed through multiple spray nozzles to suppress dust in the crushed stone in the truck bed. This effectively avoids the problem of a large amount of dust polluting the environment during the loading and transportation of crushed stone. At the same time, the dust suppression water can be discharged and recycled without adding extra weight or polluting the environment, thus ensuring that the crushed stone transportation work is more environmentally friendly.

[0031] Furthermore, in this invention, by setting an automatic blocking mechanism, when the load-bearing filter plate is loaded to a specified weight, the two flipping blocking plates rotate to close the truck bed. This can prevent overloading and also prevent the crushed stone from falling during transportation, thereby effectively avoiding overloading and preventing the crushed stone from affecting the construction environment.

[0032] Furthermore, in this invention, by setting up a synchronous recycling filtration mechanism, when spraying water to suppress dust on crushed stone, the sprayed water is filtered by a load-bearing filter plate, enters the filter cover through a water collection and recycling pipe, and is then filtered by the filter cover before entering the water storage tank for recycling and storage. This not only achieves wastewater recycling but also effectively avoids the problem of large amounts of water directly leaking onto the construction site, causing mud and affecting construction, or the problem of water containing a large amount of impurities being directly discharged and polluting the environment.

[0051] Please refer to the attached instruction manual. Figures 1-2 The present invention provides a tunnel crushing stone transfer device, which includes a bucket 1 and a frame 3. The bucket 1 is mounted on the frame 3, and a discharge plate 2 is rotatably mounted on the bucket 1.

[0052] Further, please refer to the appendix to the instruction manual. Figures 3-5The present invention provides a tunnel crushed stone transfer device, which further includes a non-powered dust suppression mechanism 4. The non-powered dust suppression mechanism 4 is installed on the truck bed 1 and is used to spray dust to suppress the crushed stone in the truck bed 1. Specifically, the non-powered dust suppression mechanism 4 includes a water storage tank 401, which is installed on the bottom side of the truck bed 1. A water outlet pipe 402 is installed on one side of the water storage tank 401, and a dust suppression water pipe 404 is connected to the water outlet pipe 402. Multiple water spray heads 405 for spraying water are installed on the dust suppression water pipe 404. Furthermore, a limiting pressure frame 407 is movably installed inside the water storage tank 401, and a pressure plate 406 is installed on the bottom side of the limiting pressure frame 407. A load-bearing filter plate 410 is provided inside the truck bed 1, and two pressure rods 411 are installed on the bottom side of the load-bearing filter plate 410. Both pressure rods 411 are movably installed on the truck bed 1. An arc-shaped drive plate 409 is slidably installed on the top side of the water storage tank 401. The arc-shaped drive plate 409 is used to lock the limiting pressure frame 407. A linkage rod 413 is rotatably installed between the arc-shaped drive plate 409 and one of the pressure rods 411.

[0053] It should be noted that in this embodiment of the invention, when the crushed stone is loaded into the truck bed 1, the load-bearing filter plate 410 is forced to move downward, which drives the two pressure rods 411 to move. The movement of the pressure rods 411 drives the arc-shaped drive plate 409 to move through the linkage rod 413, causing the arc-shaped drive plate 409 to disengage from the limiting pressure frame 407. At this time, under the pull force of the pressure spring 408, the limiting pressure frame 407 drives the water pressure plate 406 to move downward. The water pressure plate 406 applies pressure to the water in the water storage tank 401, so that the water in the water storage tank 401 enters the transfer box 403 through the water outlet pipe 402, and then enters the dust suppression water pipe 404 through the transfer box 403. Then, it is sprayed into the truck bed 1 through multiple water spray nozzles 405 to suppress dust in the crushed stone in the truck bed 1, effectively avoiding the problem of a large amount of dust pollution in the environment caused by the loading and transportation of crushed stone. At the same time, the dust suppression water can be discharged and recycled without adding extra weight or polluting the environment, thus ensuring that the crushed stone transportation work is more environmentally friendly.

[0054] More specifically, in this embodiment of the invention, an automatic blocking mechanism 5 is installed on the truck bed 1. The automatic blocking mechanism 5 is used to automatically close the truck bed 1 to block the loading of gravel. The automatic blocking mechanism 5 includes two tilting blocking plates 501, both of which are rotatably mounted on the truck bed 1. The two tilting blocking plates 501 tilt to automatically close the truck bed 1. It should be noted that in this embodiment of the invention, when the load-bearing filter plate 410 is loaded to a specified weight, the two tilting blocking plates 501 rotate to close the truck bed 1. This can prevent overloading and also prevent gravel from falling during transportation, thus effectively avoiding overloading and preventing the gravel from affecting the construction environment.

[0055] More specifically, in this embodiment of the invention, a synchronous recovery filtration mechanism 6 is also included. The synchronous recovery filtration mechanism 6 is installed on the non-powered dust suppression mechanism 4 and is used to synchronously filter and recover the wastewater discharged from the non-powered dust suppression mechanism 4. The synchronous recovery filtration mechanism 6 includes a water collection and recovery pipe 601, which is installed on the bottom side of the load-bearing filter plate 410. The bottom side of the water collection and recovery pipe 601 is inserted into the water storage tank 401, and a filter cover 602 for water filtration is rotatably installed thereon. It should be noted that in this embodiment of the invention, when spraying water to suppress dust on the crushed stone, the sprayed water is filtered by the load-bearing filter plate 410, enters the filter cover 602 through the water collection and recovery pipe 601, and is then filtered again by the filter cover 602 before entering the water storage tank 401 for recovery and storage. This not only achieves wastewater recovery but also effectively avoids the problem of large amounts of water directly leaking onto the construction site, causing mud and affecting construction, or the problem of water containing a large amount of impurities being directly discharged and polluting the environment.

[0056] Please continue to refer to the instruction manual appendix. Figures 3-5 Furthermore, the tunnel crushing stone transfer device provided in this embodiment of the invention includes a transfer box 403 for the non-powered dust suppression mechanism 4, which is installed between the water outlet pipe 402 and the dust suppression water pipe 404.

[0057] In addition, a connecting frame 414 is installed inside the transfer box 403, and a sealing water-blocking plate 415 for sealing the connecting frame 414 is movably installed on one side of the transfer box 403. Furthermore, the sealing water-blocking plate 415 and the arc-shaped drive plate 409 are equipped with mutually adsorbing magnets 416. It should be noted that in this embodiment of the invention, when the load-bearing filter plate 410 is loaded to its maximum weight, the arc-shaped drive plate 409 pushes the closed water-blocking plate 415 to move, thereby causing the closed water-blocking plate 415 to close the connecting frame 414, realizing the function of automatic water cut-off, avoiding the problem of water waste caused by continuous water spraying, and causing the two adsorption magnets 416 to attract each other; similarly, after the gravel is unloaded, when the arc-shaped drive plate 409 is reset, the arc-shaped drive plate 409 pulls the closed water-blocking plate 415 to move through the two adsorption magnets 416 and disengages from the connecting frame 414. When the arc-shaped drive plate 409 continues to move, the two adsorption magnets 416 disengage without affecting the movement of the arc-shaped drive plate 409, and at the same time, the transfer box 403 can be opened automatically.

[0058] More specifically, in this embodiment of the invention, a transverse sliding groove 417 is provided on the top side of the water storage tank 401, and an arc-shaped drive plate 409 is slidably installed in the transverse sliding groove 417. Furthermore, a downward pressure spring 408 is installed on the top side of the water storage tank 401, with the top end of the downward pressure spring 408 mounted on a limiting downward pressure frame 407. Two auxiliary wheels 418 are rotatably installed on both sides of the water storage tank 401. It should be noted that in this embodiment of the invention, when the arc-shaped drive plate 409 moves, it moves horizontally within the transverse sliding groove 417 and disengages from the limiting downward pressure frame 407. At this time, under the pull-back force of the downward pressure spring 408, the limiting downward pressure frame 407 causes the pressure plate 406 to move downward, and the pressure plate 406 applies pressure to the water in the water storage tank 401, allowing the water in the water storage tank 401 to spray out.

[0059] More specifically, in this embodiment of the invention, two return springs 412 are installed on the bottom side of the truck bed 1, and the two return springs 412 are respectively installed on the two pressing rods 411. It should be noted that, in this embodiment of the invention, the return springs 412 help the pressing rods 411 to return to their original position.

[0060] Please refer to the instruction manual attached. Figures 6-7 This invention provides a tunnel crushed stone transfer device, in which mounting brackets 502 are rotatably installed on both sides of a tilting blocking plate 501, and both mounting brackets 502 are installed on the truck bed 1; in addition, a tilting shaft 503 is rotatably installed on both mounting brackets 502, and the two tilting shafts 503 are respectively installed on both sides of the tilting blocking plate 501, and a drive gear 504 is installed on the two tilting shafts 503 near the water storage tank 401, and a drive rack frame 505 is meshed on both drive gears 504. A push rod 506 for synchronous movement is installed between the two drive rack frames 505. When the arc-shaped drive plate 409 moves, it pushes the push rod 506 to move, thereby driving the two drive rack frames 505 to move synchronously. It should be noted that, in this embodiment of the invention, when the arc-shaped drive plate 409 moves, it squeezes and pushes the round rod 506 to move, so that the push rod 506 synchronously drives the two drive rack frames 505 to move synchronously. The movement of the two drive rack frames 505 drives the two drive gears 504 to rotate, so that the two drive gears 504 drive the two flipping blocking plates 501 to rotate through the two flipping shafts 503, thereby achieving the purpose of automatically closing the truck bed 1.

[0061] Please continue to refer to the instruction manual appendix. Figures 6-7More specifically, in this embodiment of the invention, two lifting slots 507 are provided on one side of the truck bed 1. A lifting rod 508 is slidably installed in the lifting slot 507, and the lifting rod 508 is mounted on the drive rack 505. In addition, a return spring 509 is installed on the lifting rod 508, and the other end of the return spring 509 is installed on the inner wall of the lifting slot 507. It should be noted that in this embodiment of the invention, the drive rack 505 moves vertically in the lifting slot 507 through the lifting rod 508, and drives the return spring 509 to be stressed. Therefore, under the rebound force of the return spring 509, the lifting rod 508 can be reset.

[0062] Further, please refer to the appendix to the instruction manual. Figures 8-11 The embodiment of the present invention provides a tunnel crushed stone transfer device, and the synchronous recycling and filtration mechanism 6 further includes an L-shaped cleaning brush 603. The L-shaped cleaning brush 603 is installed in the water collection and recycling pipe 601, and the filter cover 602 is rotated and cleaned by the L-shaped cleaning brush 603.

[0063] Furthermore, an insertion hole 608 is provided on the top side of the water storage tank 401, and the water collection and recovery pipe 601 moves within the insertion hole 608. A water distribution baffle 611 is also installed inside the water storage tank 401. It should be noted that in this embodiment of the invention, when the load-bearing filter plate 410 moves downward, it drives the water collection and recovery pipe 601 to move within the insertion hole 608, storing the filtered water on one side of the water distribution baffle 611. Simultaneously, when the filter cover 602 rotates, it is cleaned by the L-shaped cleaning brush 603, ensuring the filtration effect of the filter cover 602.

[0064] More specifically, in this embodiment of the invention, a rotating hole 605 is provided on the bottom side of the filter cover 602, and a support rod 604 is installed on the inner wall of the bottom side of the water storage tank 401, with the top end of the support rod 604 passing through the rotating hole 605; in addition, a threaded groove 606 is provided on the support rod 604, and a driven arc-shaped block 607 is installed on the inner wall of the rotating hole 605, with the driven arc-shaped block 607 located within the threaded groove 606. It should be noted that, in this embodiment of the invention, when the water collection and recovery pipe 601 moves, it moves on the support rod 604 through the rotating hole 605, and at the same time, the water collection and recovery pipe 601 moves within the threaded groove 606 through the driven arc-shaped block 607, thereby achieving the purpose of automatic rotation of the filter cover 602 during movement. This ensures that water is thrown out of the filter cover 602 by inertia, and also allows the filter cover 602 to be cleaned, ensuring the filtration effect of the filter cover 602.

[0065] Please continue to refer to the instruction manual appendix. Figures 8-11More specifically, in this embodiment of the invention, a rotating groove 609 is provided on the bottom side of the water collection and recovery pipe 601, and a rotating ring 610 is rotatably installed in the rotating groove 609. The rotating ring 610 is mounted on the filter cover 602. It should be noted that in this embodiment of the invention, the filter cover 602 rotates within the rotating groove 609 via the rotating ring 610, thereby achieving the rotation of the filter cover 602.

[0066] In summary, the working principle of the crushed stone transfer device in the tunnel provided by the embodiments of the present invention, that is, the method of using the crushed stone transfer device of the embodiments of the present invention for crushed stone transfer in the tunnel, is as follows:

[0067] When the crushed stone is loaded into the truck bed 1, the load-bearing filter plate 410 is forced to move downward, which in turn moves the two lower pressure rods 411. This causes the two return springs 412 to be stretched. The movement of the lower pressure rods 411 drives the arc-shaped drive plate 409 to move through the linkage rod 413, causing the arc-shaped drive plate 409 to disengage from the limiting lower pressure frame 407. At this time, under the pull force of the lower pressure spring 408, the limiting lower pressure frame 407 causes the water pressure plate 406 to move downward. The water pressure plate 406 applies pressure to the water in the water storage tank 401, causing the water in the water storage tank 401 to enter the transfer box 403 through the water outlet pipe 402, and then enter the dust suppression water pipe 404 through the transfer box 403. Finally, the water is sprayed into the truck bed 1 through multiple water nozzles 405 to suppress dust in the crushed stone in the truck bed 1.

[0068] Furthermore, when the load-bearing filter plate 410 is loaded to its maximum weight, the arc-shaped drive plate 409 pushes the closed water-blocking plate 415 to move, thereby causing the closed water-blocking plate 415 to close the connecting frame 414, realizing the function of automatic water cut-off, avoiding the problem of water waste caused by continuous water spraying, and causing the two adsorption magnets 416 to attract each other; similarly, after the crushed stone is unloaded, when the arc-shaped drive plate 409 is reset, the arc-shaped drive plate 409 pulls the closed water-blocking plate 415 to move through the two adsorption magnets 416 and disengages from the connecting frame 414, and when the arc-shaped drive plate 409 continues to move, the two adsorption magnets 416 disengage without affecting the movement of the arc-shaped drive plate 409, and at the same time, the transfer box 403 can be opened automatically;

[0069] In addition, when the arc-shaped drive plate 409 moves, it squeezes and pushes the round rod 506 to move, so that the push rod 506 synchronously drives the two drive rack frames 505 to move synchronously. The movement of the two drive rack frames 505 drives the two drive gears 504 to rotate, so that the two drive gears 504 drive the two tilting blocking plates 501 to rotate through the two tilting shafts 503, thereby closing the truck bed 1. This can prevent overload problems and also prevent the gravel from falling during transportation.

[0070] Furthermore, when spraying water to suppress dust on the crushed stone, the sprayed water is filtered by the load-bearing filter plate 410 and enters the filter cover 602 through the water collection and recovery pipe 601. After being filtered by the filter cover 602, it enters the water storage tank 401 and is stored. In addition, when the load-bearing filter plate 410 moves down, it drives the water collection and recovery pipe 601 to move in the insertion hole 608, so that the water collection and recovery pipe 601 moves on the support rod 604 through the rotation hole 605. At the same time, when the water collection and recovery pipe 601 moves, it moves in the threaded groove 606 through the driven arc block 607, thereby driving the filter cover 602 to rotate. This allows the filter cover 602 to be cleaned by the L-shaped cleaning brush 603, ensuring the filtration effect of the filter cover 602.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
