Description

Technical Field

[0001] This invention belongs to the field of tunnel construction technology, specifically relating to a modified desulfurized gypsum stacking device for tunnels. Background Technology

[0002] When modified desulfurized gypsum is used to replace low-strength cement in tunnel construction, stacking devices are typically used for the handling and storage of the gypsum within the tunnel. Currently used stacking devices only facilitate the convenient stacking of materials. However, in actual tunnel construction, as the tunnel is excavated, its height and width change, making it difficult for the stacking devices to enter smoothly. Even when they do enter the tunnel, the numerous depressions in the ground make them difficult to secure. Furthermore, when using stacking devices, ventilation is poor in most areas of the tunnel, and water seepage and excessive humidity are common. When using modified desulfurized gypsum, the high moisture content often causes clumping, rendering it unusable and affecting the strength of the tunnel's sprayed support structure. Therefore, current stacking devices are unsuitable for storing modified desulfurized gypsum, and the existing technology needs further improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a modified desulfurized gypsum stacking device for tunnels that can be used in environments such as water seepage, dampness, and poor ventilation in tunnels.

[0004] A modified desulfurized gypsum stacking device for tunnels includes a movable stacking device and a conveying device. The movable stacking device includes a telescopic frame with adjustable height and width. The telescopic frame includes a first arc-shaped plate, a second arc-shaped plate, and a third arc-shaped plate. The two ends of the first arc-shaped plate face downwards and are connected to the second and third arc-shaped plates respectively through telescopic components. The lower ends of the second and third arc-shaped plates are connected by a horizontal plate. The two ends of the horizontal plate are rotatably connected to the lower ends of the second and third arc-shaped plates respectively. The lower surface of the horizontal plate is provided with several universal wheels. Several first hydraulic cylinders face the inner wall of the tunnel from the first, second, and third arc-shaped plates. A rotatable material discharge device is also provided inside the telescopic frame. There is a gap between the edge of the material discharge device and the telescopic frame for construction personnel to pass through. The material discharge device is provided with a detachable storage device and a blower. A waterproof device that can seal the material discharge device is provided on the material discharge device. The first, second, and third arc-shaped plates are made of elastic metal plates.

[0005] Furthermore, the conveying device includes two slide rails and a transport device. The transport device includes a fixed plate and a support plate. The lower surface of the fixed plate is provided with several grooves that cooperate with the slide rails, forming a structure in which the grooves can move along the length direction of the slide rails. The fixed plate is provided with a vertical rod, the length direction of which is perpendicular to the upper surface of the fixed plate. A sliding sleeve is fitted on the vertical rod, and a pull rope is connected to the first sleeve. A fixed pulley is provided at the upper end of the vertical rod, and the pull rope passes around the fixed pulley and connects to one end of a winch. The winch is mounted on the upper surface of the fixed plate. The support plate is connected to the first sleeve. Several second hydraulic cylinders are provided on the upper surface of the support plate. The telescopic rods of the second hydraulic cylinders are connected to a fixed seat, and the fixed seat is detachably connected to a material storage device.

[0006] Furthermore, the storage device includes a magnetic plate, with two support blocks on the lower surface of the magnetic plate. A first motor is installed inside the fixed base, and the output end of the first motor is connected to a first gear. The support blocks have a first groove with openings at both ends, and the length direction of the first groove is the same as the length direction of the support block. The first groove has a meshing tooth that cooperates with the first gear. The magnetic plate contains a first magnet, which is encased in a metal shell. The upper surface of the magnetic plate is connected to two support bases via a fourth motor. The upper part of the support base has a second groove, and a second motor is installed on the second groove. The output end of the second motor passes through the second groove, and the output end of the second motor is vertically connected to a connecting rod in the same plane. The upper end of the connecting rod is connected to the storage bin.

[0007] Furthermore, the storage bin is a cuboid box, comprising an outer shell and an inner shell. The inner shell has uniformly distributed nanopores, and the outer shell has several first ventilation holes. A third motor is located between the outer shell and the inner shell, with its output shaft rotatably connected to the outer shell. The end of the third motor extends out of the outer shell and is connected to a rotating disk. The rotating disk has second ventilation holes. When the rotating disk rotates, the first and second ventilation holes overlap, forming a structure where airflow can enter between the outer and inner shells. When the first and second ventilation holes are misaligned, the rotating disk can block the first ventilation holes. The top of the storage bin has an inlet and outlet, with a closable sealing cover on the inlet and outlet.

[0008] Furthermore, the feeding device is divided into several placement platforms by several partition plates. The bottom of the placement platform in the middle of the feeding device is provided with magnetic blocks that attract each other to the magnetic plate. Two support blocks can be placed between the two magnetic blocks. A hot air blower is placed on the placement platform at the edge of the feeding device.

[0009] Furthermore, the feeding device is a circular frame, with the upper and lower parts of the circular frame rotatably connected to the telescopic frame via vertical rods. The waterproof device includes two waterproof sheets, the edges of which are connected to the edges of the circular shaft surface of the circular frame and can cover the circular shaft surface. The middle and lower edges of the waterproof sheets are provided with pull-out zippers, forming a structure in which the waterproof sheets can be rolled up from below to be stored in the circular frame.

[0010] Furthermore, the telescopic component includes a second sleeve, which is arc-shaped and has an internal rubber pad to prevent it from falling off due to gravity. The second sleeve is fitted at the connection between the first arc plate and the second arc plate. The lower end of the first arc plate has a first through hole, the upper end of the second arc plate has a second through hole that cooperates with the first through hole, and the upper end of the third arc plate has a third through hole that cooperates with the first through hole, forming a structure in which the lower end of the first arc plate and the second arc plate or the third arc plate 103 are detachably connected by screws and nuts.

[0011] This invention includes a stacking device and a conveying device. The conveying device has a rotatable storage bin for easy feeding and unloading. During unloading, the inlet and outlet can be oriented downwards for convenient discharge. The telescopic frame of the stacking device can be adjusted in height and width to better suit the environment of tunnels. Simultaneously, the stacking device includes a rotatable unloading device with a gap between its edge and the telescopic frame for personnel passage. This allows for placement in areas requiring personnel access, ensuring personnel can pass through the gap. Alternatively, rotating the unloading device can adjust the gap width to increase personnel throughput, making the placement of the conveying device more flexible. Furthermore… This invention also includes a waterproofing device to effectively prevent water seepage in the tunnel from affecting the quality of the modified desulfurized gypsum. The rotatable discharge device can also adjust the angle of the storage bin by rotating it, allowing the storage bin to be vertical with the maximum plate facing the wind direction. When the tunnel is ventilated, this ensures that the modified desulfurized gypsum in the storage bin is in a ventilated environment, using natural wind to reduce the moisture content in the modified desulfurized gypsum and maintain its quality. In addition, the storage bin can be sealed in humid environments to reduce moisture loss. This invention can be used in environments with water seepage, humidity, and poor ventilation in tunnels, ensuring the quality of the modified desulfurized gypsum during storage.

The first arc-shaped plate 101, the second arc-shaped plate 102, the third arc-shaped plate 103, and the horizontal plate 104 are connected. The horizontal plate 104 forms a ring-shaped frame. The lower surface of the horizontal plate 104 is equipped with six casters 105, which allow the entire movable stacking device to move in the tunnel and be placed in a suitable position. Several first hydraulic cylinders 3 face the inner wall of the tunnel, with the base of the first hydraulic cylinder 3 fixed to the first arc plate 101, the second arc plate 102, or the third arc plate 103. The telescopic rod of the base of the first hydraulic cylinder 3 faces the side wall inside the tunnel. The telescopic frame 1 is also equipped with a rotatable material feeding device 4.

The lower end of the first arc-shaped plate 101 is connected to the second arc-shaped plate 102 or the third arc-shaped plate 103. The conveying device includes two slide rails 8 and a transport device. The two slide rails 8 are arranged parallel to each other in the same plane to form a transport track. The transport device includes a fixed plate 9 and a support plate 10. The surface of the fixed plate 9 is parallel to the length direction of the two slide rails 8. The lower surface of the fixed plate 9 is provided with several grooves 11 that cooperate with the slide rails 8, forming a structure in which the grooves 11 can move along the length direction of the slide rails 8. The fixed plate 9 is provided with a vertical rod 12, the length direction of which is parallel to the fixed plate 8. The upper surface of the fixed plate 9 is vertical. A first sleeve 13 is slidably fitted on the upright 12. A pull rope 14 is connected to the first sleeve 13. A fixed pulley 15 is provided at the upper end of the upright 12. The pull rope 14 passes around the fixed pulley and connects to one end of the winch 20. The winch 20 is set on the upper surface of the fixed plate 9. A support plate 10 is connected to the first sleeve 13. Several second hydraulic cylinders 16 are provided on the upper surface of the support plate 10. The base of the second hydraulic cylinder 16 is connected to the upper surface of the support plate 10. The telescopic rod of the second hydraulic cylinder 16 is connected to the fixed seat 17. The fixed seat 17 is detachably connected to the material storage device 5.The storage device 5 includes a magnetic plate 501. Two support blocks 502 are provided on the lower surface of the magnetic plate 501. The length direction of the support blocks 502 is perpendicular to the length direction of the upright in the same plane. A first motor 503 is housed in the fixing base 17. The output end of the first motor 503 is connected to a first gear 504. The fixing base has recesses for placing the first motor 503 and the first gear 504. The circular shaft surface of the first gear 504 is perpendicular to the surface of the magnetic plate 501. A first groove 505 with openings at both ends is provided on the support blocks 502. The length direction of the first groove 505 is the same as the length direction of the support block 502. Gears that cooperate with the first gear 504 are provided in the first groove 505. The magnetic plate 501 contains... The first magnet is encased in a metal shell. The upper surface of the magnetic plate 501 is connected to two support seats 506 via a fourth motor 22. The output end of the fourth motor 22 is connected to the support seat 506. A second groove 507 is provided on the upper part of the support seat 506. A second motor 508 is provided on the outer wall of the second groove 507. The output end of the second motor 508 passes through the second groove 507. The output shaft of the second motor 508 is vertically connected to a connecting rod 509 in the same plane. The connecting rod 509 is connected to the middle section of the output shaft of the second motor 508. The end of the output shaft of the second motor 508 is rotatably connected to the other side wall of the second groove 507 via a bearing. The upper end of the connecting rod 509 is connected to the storage bin 18. The storage bin 18 is a rectangular box, comprising an outer shell 181 and an inner shell 182. The inner shell 182 has uniformly distributed nanopores. The outer shell 181 has several first ventilation holes 183. A third motor 184 is located between the outer shell 181 and the inner shell 182. The output shaft of the third motor 184 is rotatably connected to the outer shell 181. The end of the third motor 184 extends out of the outer shell 181 and is connected to a rotating disk 185. The upper part is provided with a second ventilation hole 186. After the rotating disk 185 rotates, when the first ventilation hole 183 and the second ventilation hole 186 overlap, an airflow can enter between the outer shell 181 and the inner shell 182. When the first ventilation hole 183 and the second ventilation hole 186 are misaligned, the rotating disk 185 can block the first ventilation hole 183. The top of the storage bin 18 is provided with an inlet / outlet 187, and the inlet / outlet 187 is provided with a sealing cover 188 that can be opened and closed. The discharge device 4 is divided into several placement platforms 41 by several partition plates. The several placement platforms 41 are distributed in a mesh pattern in the discharge device. The bottom of the placement platform 41 in the middle of the discharge device 4 is provided with a magnetic block 42 that attracts the magnetic plate. Two support blocks 502 can be placed between the intervals of the two magnetic blocks 42. A hot air blower 6 is placed on the placement platform 41 on the edge of the discharge device 4, and the air outlet of the hot air blower 6 faces the placement platform 41 in the middle of the discharge device 4.The material feeding device 4 is a circular frame. The upper and lower parts of the circular frame are rotatably connected to the telescopic frame through the vertical rod 21. The waterproof device 7 includes two waterproof cloths 71. The edges of the two waterproof cloths 71 are respectively connected to the edge of the circular shaft surface of the circular frame and can cover the circular shaft surface. The middle and lower edges of the waterproof cloths 71 are provided with pullable zippers 72, forming a structure in which the waterproof cloth can be rolled up from below to be stored in the circular frame. The telescopic component 2 includes a second sleeve 201, which is arc-shaped and has a rubber pad inside to prevent it from falling off due to gravity. The second sleeve 201 is fitted at the connection position between the first arc plate 101 and the second arc plate 102. The lower end of the first arc plate 101 has a first through hole 106, the upper end of the second arc plate 102 has a second through hole 107 that cooperates with the first through hole 106, and the upper end of the third arc plate 103 has a third through hole 108 that cooperates with the first through hole 106, forming a structure in which the lower end of the first arc plate 101 and the second arc plate 102 or the third arc plate 103 are detachably connected by screws and nuts.

[0030] In use, move the telescopic frame 1 to the desired location within the tunnel, then push the casters 105 to move it to a suitable position. This position can be one with relatively good ventilation or one convenient for construction. Because there is a gap between the edge of the material dispensing device 4 and the telescopic frame 1 that allows construction personnel to pass through, and because the material dispensing device 4 can rotate, the placement of the entire device is relatively flexible and will not affect the passage and work of construction personnel. It is also convenient to move. After placement, open the first hydraulic cylinder 3. The telescopic rod of the first hydraulic cylinder 3 extends and inserts into the inner wall of the tunnel, fixing the telescopic frame 1 inside the tunnel. If the tunnel height is low, the first hydraulic cylinder 3 can be slid... The second sleeve 201 moves downward, the screws and nuts are removed, and the length of the lower end of the first arc plate 101 and the second arc plate 102 or the third arc plate 103 is lengthened. The telescopic frame 1 moves upward. If the sides of the tunnel are narrow, the length of the lower end of the first arc plate 101 and the second arc plate 102 or the third arc plate 103 can be shortened. At the same time, the second arc plate 102 or the third arc plate 103 can be rotated inward to shorten the interval between the second arc plate 102 or the third arc plate 103, thus adapting to narrow tunnels. When encountering poor ventilation, the material discharge device 4 can be rotated, and the rotating disk 185 can be rotated to open the first ventilation hole 183 and the second ventilation hole 183. The holes 186 overlap to form an airflow channel that allows air to enter the outer shell 181 and the inner shell 182. The second motor 508 is activated, raising the storage bin 18 to a vertical position. Then, the discharging device 4 is rotated to align the first ventilation hole 183 and the second ventilation hole 186 on the storage bin 18 with the wind direction, ensuring airflow. If the storage device is located in an environment where the tunnel is leaking water or is damp, the rotating disc 185 can be rotated to offset the first ventilation hole 183 and the second ventilation hole 186, ensuring the storage bin 18 is sealed. Then, a waterproof cloth 71 is placed over the discharging device 4. After covering, the zipper 72 is pulled to allow discharging. The device 4 is in a closed state to prevent water from entering the discharge device 4. When there is no more water seepage in the tunnel and it is relatively dry, the zipper 72 can be opened, and the waterproof cloth 71 can be rolled up to the top of the discharge device 4 and tied with a rope to prevent the waterproof cloth 71 from falling. If the environment is found to be humid, the first ventilation hole 183 and the second ventilation hole 186 can be overlapped, and the hot air blower can be turned on to blow hot air into the storage bin 18. The hot air blower 6 does not need to be turned on to a high wind speed mode. It can gradually send in hot air through a small wind to give the storage bin 18 a dry environment. This can slowly evaporate the moisture in the modified desulfurized gypsum in the storage bin 18 and prevent the modified desulfurized gypsum in the storage bin 18 from clumping.

[0031] When using a conveyor device to transport the storage bin 18, the support block 502 can be placed on the fixed seat 17 first. Construction workers push the fixed plate 9 along the track. When it reaches the telescopic frame 1 where the material needs to be placed, the winch 20 is turned on, and the support plate 10 moves upward. Before reaching the placement platform 41, the second hydraulic cylinder 16 is turned on, and the magnetic plate 501 rises. Then, the first motor 503 is turned on, and the magnetic plate 501, due to the rotation of the first gear 504, can push the support block 502 towards the placement platform 41. The second hydraulic cylinder 16 raises the magnetic plate 501 slightly above the magnetic block, and then the magnetic plate 501 moves towards the magnetic block 42, causing the magnetic plate 501 to attract the magnetic block 42. The magnetic plate 501 is placed on the magnetic block 42, the height of which is greater than that of the support block 502. After being placed on the placement platform 41, the support block 502 is positioned between the two magnetic blocks. When moving the magnetic plate 501 on the placement platform 41, the construction personnel only need to adjust its position from the side. When modified desulfurized gypsum is needed, the support plate 10 is moved upward to the placement platform 41 where the material needs to be picked up. The construction personnel place the magnetic plate 501 on the fixed seat 17 and then use a winch to move the magnetic plate 501 and the storage bin 18 downward. After moving it to the position where the material needs to be used, the sealing cover 188 on the inlet / outlet 187 is opened, and then the second motor 508 is rotated to make the inlet / outlet 187 pour out the material downward. After use, the sealing cover 188 is closed.
