Description

Technical Field

[0001] This invention belongs to the technical field of chute equipment, specifically relating to a concrete transport chute device for high-face rockfill dam panels. Background Technology

[0002] In the construction of some dams, in order to make the two sides of the dam body have a stronger load-bearing capacity, the two sides of the dam body are usually constructed with reinforced concrete to form an inclined high-face rockfill dam. Due to the large height difference of the dam body and the fact that the main casting surface of the dam body is mostly inclined, the existing equipment cannot directly pour concrete into the woven steel mesh structure installed on the dam body. It is necessary to use a chute device to transport the concrete from the height down the inclined dam body, and achieve the purpose of pouring with the help of gravity.

[0003] Currently, most concrete transport chute devices use φ8 steel wire ropes connected by rings to form a whole, making it easy to splice and secure multiple chutes into a chute channel. The top of the steel wire rope is fixed to the winch foundation to prevent the chute from falling off. This connection method means that as construction progresses, the pouring location will gradually rise towards the top of the dam as the dam height increases. At this point, it is necessary to dismantle the bottom chute device. Then, as construction continues, the bottom chute will be dismantled section by section. Because the chutes are connected and fixed by steel wire ropes, coupled with the influence of the dam's inclined surface, workers not only spend a lot of time when dismantling the steel wire ropes, but also face the risk of slipping on the slope. Therefore, a concrete transport chute device for high-face rockfill dams is proposed. Summary of the Invention

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example:

[0045] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides a concrete transport chute device for a high-face rockfill dam, including a chute 1. A top opening 2 is fixedly connected to one side of the chute 1, and a bottom opening 3 is fixedly connected to the other side of the chute 1. Through the cooperation of the top opening 2 and the bottom opening 3, the concrete transported from the previous chute 1 can fall directly onto the next chute 1, avoiding leakage of concrete between two adjacent chute 1s. A building mechanism 6 is installed on both sides of the chute 1. Through the cooperation of the building mechanism 6 and the winch, the device can be quickly disassembled. A material distribution mechanism 5 is installed at the bottom of the chute 1. The material distribution mechanism 5 can prevent the concrete transported from the chute 1 from accumulating in one construction area during pouring.

[0046] The assembly mechanism 6 includes two connecting blocks 601. A clamping plate 602 is fixedly connected to the middle of each connecting block 601. An installation block 603 is slidably connected to one side of the outer perimeter of the clamping plate 602. A housing 604 is fixedly connected to the side of the installation block 603 away from the chute 1. A slider 605 is slidably connected inside the housing 604. A sliding pin 606 is fixedly connected to the middle of the slider 605. A compression spring 607 is sleeved around the outer perimeter of the sliding pin 606. A partition 608 is fixedly connected to the middle of the side of the housing 604 away from the chute 1. An unlocking frame 609 is fixedly connected to the edge of the side of the housing 604 away from the chute 1. An unlocking frame 609 has a movable groove 610 inside. A movable block 611 is slidably connected inside the movable groove 610. A trapezoidal groove 612 is opened inside the movable block 611. A trapezoidal block 613 is slidably connected inside the trapezoidal groove 612. A winch wire rope 614 is fixedly connected to the outer side of the trapezoidal block 613.

[0047] When the bottom chute 1 needs to be removed, the winch at the top of the dam works, winding up the winch wire rope 614 and pulling the trapezoidal block 613 upwards inside the slide rail 615 until the slide rail 615 passes through the interface 616 and enters the trapezoidal groove 612. At the same time, the crane at the bottom of the dam works, and the images transmitted by the remote monitoring equipment ensure that the hook and the lifting ring 4 on the crane are engaged. At this time, the winch continues to pull the winch wire rope 614 to move the trapezoidal block 613. The movement of the trapezoidal block 613 will squeeze the movable block 611, thereby pushing the movable block 611 to move outwards towards the movable groove 610. At this time, the movable block 611 will pull the sliding pin 606 to slide outwards. This causes the slider 605 on the sliding pin 606 to move and compress the compression spring 607. Simultaneously, the sliding pin 606 disengages from the inside of the clamping plate 602, unlocking the clamping plate 602 and the mounting block 603. Meanwhile, workers standing on the edge of the dam or on the completed dam section use long poles and knives to cut the ropes binding the foot ties 8 and the steel mesh structure. At this point, the bottom chute 1, no longer secured by the erection mechanism 6, slides downwards a distance, separating the clamping plate 602 from the mounting block 603, thus removing the bottom chute 1 from the overall structure. A slide rail 615 is fixedly connected to one side of the unlocking frame 609, and an interface 616 is fixedly connected to the other side of the unlocking frame 609. A handle 617 is fixedly connected to the side of the movable block 611 away from the chute 1. When assembling the chute 1, the worker only needs to pull the two pull rods 508 on the previous chute 1 to disengage the locking block 507 from the slot 505 and into the material distribution plate 503. At this time, the material distribution plate 503 is flipped downwards to align the two adjacent chute 1s, so that the top opening 2 and the bottom opening 3 are engaged, and the interface 616 and the slide rail 615 are engaged. At the same time, the trapezoidal groove 612 is inserted into the trapezoidal block 613. The worker pulls the handle 617 to bring the sliding pin 606 into the housing 604. At the same time, the trapezoidal groove 612 and the slide rail 615 are completely connected. At this time, the two chute 1s are fully aligned and in contact, and the winch releases... The retracted winch wire rope 614 causes the trapezoidal block 613 to slide down inside the slide rail 615 and pass through the trapezoidal groove 612 and the interface 616 into the slide rail 615 on the next chute 1. At this time, the worker releases the handle 617, and the compressed spring 607 resets, pushing the slider 605 and causing the sliding pin 606 to insert into the clamping plate 602, locking the clamping plate 602 inside the mounting block 603. At the same time, the sliding pin 606 will also pull the movable block 611 back to reset into the movable groove 610. Meanwhile, the trapezoidal groove 612 and the slide rail 615 are staggered and leave a gap for the winch wire rope 614 to pass through. By repeating this process, the device can be quickly assembled.

[0048] The mounting block 603 is fixedly connected to the outside of the chute 1 on the side away from the housing 604. The slide rail 615 and the chute 1 are fixedly connected by two connecting rods 7 to ensure that the assembly mechanism 6 can be stably fixed on the chute 1, thereby ensuring that the assembly mechanism 6 between each section can be stably connected together.

[0049] Both sides of the top of the chute 1 are fixedly connected with flat lifting rings 4. With the cooperation of the flat lifting rings 4 and the crane, the chute 1 located at the bottom of the device can be remotely and automatically dismantled. Both sides of the bottom of the chute 1 are fixedly connected with two binding feet 8. The bottom of the binding feet 8 is equipped with protrusions that can engage with the steel mesh structure. With the binding rope, the binding feet 8 can be firmly fixed to the steel mesh structure in the dam construction area to ensure the overall stability of the device.

[0050] One end of the sliding pin 606 passes through the housing 604 and the mounting block 603 and is located inside the clamping plate 602. The other end of the sliding pin 606 passes through the partition 608 and is fixedly connected to one side of the middle of the movable block 611. This allows the sliding pin 606 to lock the clamping plate 602 inside the trapezoidal block 613. At the same time, the movement of the movable block 611 can easily drive the sliding pin 606 to automatically disengage and unlock from the clamping plate 602. One end of the compression spring 607 is fixedly connected to the middle edge of the slider 605, and the other end of the compression spring 607 is fixedly connected to the middle edge of the partition 608. The compression spring 607 tightly holds the slider 605 in place, preventing the sliding pin 606 from disengaging from the clamping plate 602.

[0051] The end of the slide rail 615 away from the unlocking frame 609 engages with the outer side of the interface 616, ensuring that the slide rails 615 on each section of the building mechanism 6 can be aligned through the interface 616, making it easy for the trapezoidal block 613 to slide inside the slide rail 615 of each section. The top opening 2 and the bottom opening 3 engage to prevent leakage when concrete flows and is transported between two adjacent chutes 1.

[0052] One side of the trapezoidal block 613 is slidably connected inside the slide rail 615, and the other side of the trapezoidal block 613 passes through the trapezoidal groove 612. The trapezoidal groove 612, the interface 616 and the slide rail 615 are connected. As the trapezoidal block 613 continuously passes through the interior of each section of the building mechanism 6, the building mechanism 6 can be controlled to unlock and quickly unlock and dismantle the chute 1 at the bottom that has reached the construction height.

[0053] The material distribution mechanism 5 includes two supports 501 and a crossbar 510. Limiting shafts 502 are rotatably connected to the inner sides of both supports 501. A material distribution plate 503 is fixedly connected to one side of the outer periphery of the limiting shaft 502, and a torsion spring 504 is sleeved on the other side of the outer periphery of the limiting shaft 502. A slot 505 is opened at the top of the material distribution plate 503. A stop block 506 is slidably connected inside the material distribution plate 503. A locking block 507 is fixedly connected to the bottom of the stop block 506. A pull rod 508 is fixedly connected to the top of the stop block 506, and a spring 509 is sleeved on the outer periphery of the pull rod 508. The crossbar 510 is fixedly connected to one side of the top of the top opening 2. Fixing blocks 511 are fixedly connected to both sides of the crossbar 510, and a positioning rod 512 is fixedly connected between the two fixing blocks 511. When the bottom chute 1 falls off, the material distribution plate 503 on the previous chute 1 will quickly flip upwards under the action of the torsion spring 504, causing the slot 505 on the material distribution plate 503 to... The positioning rod 512 installed directly on the crossbar 510 engages with the positioning rod 512. Due to inertia and the force of the torsion spring 504, the outer periphery of the positioning rod 512 can cooperate with the arc-shaped surface of the locking block 507, pushing the locking block 507 upward. This causes the stop block 506 to compress the spring 509. At the same time, the positioning rod 512 will be locked between one side of the vertical surface of the locking block 507 and the inside of the slot 505. Then, the spring 509 pushes the locking block 507 to fall quickly, sealing the inside of the slot 505, and thus restricting and fixing the material distribution plate 503 to the top opening 2. At this time, the concrete at the top flows down the chute 1 at the top of the dam body and finally reaches the bottom chute 1. The flowing concrete will be divided into three streams by the two arc-shaped material distribution plates 503 and poured onto the steel mesh structure. This prevents the poured concrete from all accumulating in one area, reducing the time required for subsequent leveling and improving work efficiency.

[0054] One end of the torsion spring 504 is fixedly connected to the outside of the distribution plate 503, and the other end of the torsion spring 504 is fixedly connected to the inside of the bracket 501. This allows the distribution mechanism 5 on the previous chute 1 to open after the bottom chute 1 is removed, thus diverting the concrete and preventing it from being concentrated in the same area during pouring. Furthermore, the distribution mechanisms 5 on other chute 1 will not open before the bottom chute 1 is removed, to avoid affecting the flow rate of the conveyed concrete and delaying construction efficiency. One end of the spring 509 is fixedly connected to the inner top wall of the distribution plate 503, and the other end of the spring 509 is fixedly connected to the top edge of the stop block 506. The cooperation between the spring 509 and the locking block 507 can lock the positioning rod 512 and the distribution plate 503, preventing the distribution plate 503 from shaking due to the impact force generated during concrete conveying.

[0055] The outer periphery of the positioning rod 512 is set between the inner wall of the slot 505 and the outer side of the locking block 507. The cross section of the side of the locking block 507 away from the positioning rod 512 is arc-shaped, so that when the material distribution plate 503 is driven by the torsion spring 504, the locking block 507 can easily pass over the positioning rod 512 and lock the material distribution plate 503 onto the positioning rod 512.

[0056] The top of the material distribution plate 503 and the bottom of the chute 1 are in contact to prevent the material distribution mechanism 5 located on the bottom of the chute 1 from opening, ensuring that the material distribution mechanism 5 at the bottom of the entire device is in the open state. The winch wire rope 614 passes through the slide rail 615, the trapezoidal groove 612 and the interface 616. The winch wire rope 614 can pass through the slide rail 615 on each section of the erection mechanism 6 normally, so as to easily unlock and dismantle the bottom chute 1.

[0057] Working Principle: When the bottom chute needs to be removed, the winch at the top of the dam works, winding up the winch wire rope and pulling the trapezoidal block upwards inside the slide rail until the slide rail passes through the interface and enters the trapezoidal groove. Simultaneously, the crane at the bottom of the dam works, ensuring the hook and lifting ring on the crane are engaged via video transmitted from a remote monitoring device. The winch continues to pull the winch wire rope, moving the trapezoidal block. This movement compresses the movable block, pushing it outwards into the movable groove. The movable block then pulls the sliding pin outwards, causing the slider on the sliding pin to move and compress the spring. Simultaneously, the sliding pin disengages from the clamping plate, unlocking the clamping plate and the mounting block. Workers standing on the edge of the dam or on the completed dam section use long poles and cutters to cut the ropes binding the foot and the reinforcing mesh structure. At this point, the bottom chute, no longer secured by the erection mechanism, slides downwards a distance, separating the clamping plate and the mounting block, thus removing the bottom chute from the overall structure. The hooks and lifting rings on the machine work together to ensure that the dismantled chute does not slip off the dam body. The crane removes the dismantled chute from the dam body without requiring workers to enter the dam construction site for dismantling. After the bottom chute is removed, the distribution plate on the previous chute will quickly flip upward under the action of the torsion spring, so that the slot on the distribution plate will directly engage with the positioning rod installed on the crossbar. At this time, due to inertia and the force of the torsion spring, the outer periphery of the positioning rod can cooperate with the arc surface of the locking block, pushing the locking block upward, causing the stop block to compress the spring. At the same time, the positioning rod will be locked between one side of the vertical surface of the locking block and the inside of the locking slot. Then the spring pushes the locking block to fall quickly, sealing the inside of the locking slot, and thus restricting and fixing the distribution plate to the top opening. At this time, the concrete at the top flows down the chute at the top of the dam body and eventually reaches the bottom chute. The flowing concrete will be divided into three streams by the two arc-shaped distribution plates and poured into the steel mesh structure, so that the poured concrete will not all accumulate in one area.
