Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to a special material transportation device for tunnel engineering, and also relates to a special material transportation method for tunnel engineering. Background Art

[0002] The construction site working conditions are complex. For example, during the construction of many tunnels and winding mountain roads, sometimes explosives are needed, or when a tunnel collapses, support materials need to be repaired, or sometimes radioactive substances are needed for flaw detection. At this time, there is a certain degree of danger, and it is not convenient to operate manually and with conventional ordinary vehicles. At the same time, it is more difficult to enter narrow tunnel passage working conditions. Special materials such as flammable and explosive substances, toxic and harmful substances, and radioactive substances are usually transported by special vehicles. Special vehicles are large in volume and vary in shape. When only a small amount of special materials are needed, or when multiple different special materials are needed, using special vehicles will cause waste of resources. And when the transportation passage is relatively tortuous and narrow, it is difficult for special vehicles to pass through. Summary of the Invention

[0017] Optionally, an explosion-proof box is installed inside the main transportation box part.

[0018] Correspondingly, the present invention also claims to protect a special material transportation method for tunnel engineering, including:

[0019] Device combination and assembly: When starting to connect the auxiliary transportation box part and the main transportation box part, control the gear on it to rotate on the rack track of the housing lifting track through the fourth stepping motor, thereby driving the lifting housing to descend. When it descends to an appropriate height, control the sixth electric push rod to push out the push plate downward. When the push plate touches the ground, the support of the entire main transportation box part is switched from the universal wheels to the push plate. Continue to extend the push plate to realize the rising of the transportation box part. After raising the main transportation box part, control the movement of the auxiliary transportation box part until the T-shaped connecting rod socket is directly below the T-shaped connecting rod. Lower the main transportation box part, insert the T-shaped connecting rod into the T-shaped connecting rod socket, and at the same time, the splicing track support rod descends and inserts into the splicing track support rod socket to complete the splicing;

[0020] Transfer orbit splicing: When splicing the transfer orbit section between the main transport box part and the auxiliary transport box part, insert the splicing orbit support rod at the lower part of the end of the splicing orbit into the splicing orbit support rod socket. When orbit splicing is required, control the lowering of the extended lifting housing through the fourth stepping motor so that the splicing orbit drops to the docking position, that is, the height of the splicing orbit fixing plate is lower than that of the L-shaped baffle. At this time, push out the L-shaped baffle through the third electric push rod so that it covers the splicing orbit fixing plate, and push the third electric push rod to make the splicing orbit fixing plate fit completely with the L-shaped baffle. Through the pressure at the upper and lower ends of the splicing orbit fixing plate, the entire main transport box part, the auxiliary transport box part and the splicing orbit on them are stably connected. At this time, the orbit on it forms a complete passage;

[0021] Transfer between transport boxes: When used for storing special materials, at this time, the mobile transfer part is located on the cross-shaped transfer double track at the outermost side of the auxiliary transport box part. Control the bottom plug board to insert into the triangular slot through the plug board stepping motor, and the materials can be stably loaded into the three rectangular openings of the alloy transfer frame. When the mobile transfer part moves above the lifting transfer unit on the transfer orbit part, the first electric push rod pushes the bottom plate of the rectangular transport slot below the bottom plug board. Open the bottom plug board through the plug board stepping motor, and the materials slide to the bottom plate of the rectangular transport slot through the front slope of the plug board. Lower the first electric push rod, and the materials are transferred to the lifting transfer unit at this time;

[0022] Transfer inside and outside the storage box: When the mobile transfer part moves above the lifting transfer unit through the transfer orbit part, lift the horizontal plate of the lifting platform to the position of the storage top plate through the lifting electric trolley, align the three storage slots of the mobile transfer part with the three rectangular transport slots, push up the bottom plate of the rectangular transport slot to below the bottom plug board through the first electric push rod, open the bottom plug board, and the materials fall on the bottom plate. Then lower the bottom plate to the bottom of the rectangular transport slot, and then lower the entire lifting transfer unit into the storage box through the lifting electric trolley, and the screw slide table part transfers the materials inside the rectangular transport slot;

[0023] Internal transfer in the main storage box: When it is necessary to transfer the materials sent down by the lifting transfer unit, when transferring the main transport box part, first use a set of screw slide table jaw groups to clamp, rotate and open the door of the explosion-proof box and move it to the rightmost end of the screw slide table part. At this time, lower the lifting transfer unit, drive the first slide table to move above the rectangular transport slot through the first stepping motor, adjust the longitudinal position of the third slide table on it through the third stepping motor so that it is directly above the rectangular transport slot. At this time, control the second stepping motor to adjust the second slide table to lower it to an appropriate height, push out the rotating motor through the fourth electric push rod, and then control the angle through the rotation of the rotating motor. Finally, clamp the materials with the electric jaw, move the screw slide table jaw group in the opposite way to leave the rectangular transport slot and transport the materials into the explosion-proof box. After all the transportation is completed, close the explosion-proof box through the moving screw slide table jaw group;

[0024] Internal transfer within the secondary storage box: When part of the secondary transport box is used for internal storage, an empty special storage box can be moved onto the cross-shaped transport track. The cross-shaped track mounting platform is raised by the fifth electric push rod so that it enters the transfer range of the lead screw slide table part. Then, the material is transferred into the special storage box by the lead screw slide table gripper group. After storage, the cross-shaped track mounting platform is lowered by the fifth electric push rod until it is flush with the first-layer storage track mounting plate. The special storage box enters the interior of the secondary storage box part through the connected cross-shaped storage track. Then, another empty special storage box is moved onto the cross-shaped transport track, and the above operations are repeated for further storage or retrieval.

[0025] Closed transportation of the device: When the box needs to be transported, the fourth stepping motor drives the gear on it to rotate on the outer shell lifting track, thereby lifting the lifting housing to the highest position. At this time, the lifting housing completely covers the open part of the upper part of the transport box. At the same time, the height of the first rectangular opening corresponds to that of the extended fixed plug board. The plug board power plate is pushed out by the seventh electric push rod. Under the action of the plug board connecting rod, the extended fixed plug board slides outwards on the plug board track and then inserts into the first rectangular opening, which can not only fix the lifting housing but also block a certain part of the splicing part above the lifting housing and the transport box to prevent the collapse and falling objects in the tunnel from affecting the interior of the box.

[0026] Furthermore, the splicing can be carried out simultaneously on four sides, and finally a cluster of the "4 + 1" secondary transport box part and the main transport box part is formed for passing through the wide part of the tunnel; when passing through the narrow part of the tunnel, it can be spliced into a straight-line "2 + 1" cluster of the secondary transport box part and the main transport box part in the same way; if the tunnel is further narrowed, it can also be spliced into a "1 + 1" cluster of the main transport box part and the secondary transport box part.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. The present invention controls the lifting and transfer unit to lift inside the storage box through the lifting electric trolley, enabling the storage box to quickly switch between the sealed and open states, ensuring the stability and controllability of the material storage environment. The first electric push rod at the bottom of the lifting platform cross plate can push the bottom plate of the rectangular transport groove up and down. When it moves below the bottom plug board, the material can be smoothly dropped onto the bottom plate by opening the bottom plug board. Then, the bottom plate is lowered to store the material in the rectangular transport groove, and then the rectangular transport groove transports the material into the storage box for transfer and storage. This method of transporting special materials is relatively stable, and the whole process is completed by electric components, reducing human interference and improving efficiency.

[0029] 2. The present invention realizes the rapid connection and disconnection between the main and auxiliary transport boxes through the combination of T-shaped connecting rods and sockets. The number of auxiliary transport boxes can also be increased according to actual needs. Only an additional T-shaped connecting rod combination needs to be added between the auxiliary transport boxes to complete the connection, forming a cluster of special material transport devices for tunnel engineering similar to a nine-square grid, greatly increasing the special material transport volume. At the same time, it adapts to the transport needs of narrow or wide roads, improving the adaptability of the device. At the same time, due to the spring support provided at the bottom of the T-shaped connecting rod and the second electric push rod provided at the bottom of the T-shaped connecting rod socket, when the second electric push rods of the four-sided auxiliary transport boxes jointly push up the T-shaped connecting rod, under the action of the spring support, the main transport box can be lifted and buffered, effectively adapting to bumpy roads and improving the stability of the device.

[0030] 3. The external transfer of the present invention is completed by a track group composed of a cross-shaped transfer double track and a splicing track. This track group can be fixed and disconnected through the cooperation of the second electric push rod, the third electric push rod, the L-shaped baffle, and the splicing track fixing plate. When in need of use, the track can be quickly connected, enabling the electric trolley to move the mobile transfer part between each transport box. When not in need of use, it can be quickly separated without interfering with the overall transport and the shock absorption of the main transport box. The transfer efficiency is high, the space occupation is small, and the adaptability is strong.

[0031] 4. The present invention realizes the three-dimensional movement of the clamping device through the designed screw slide table clamping jaw group, and at the same time, it cooperates with the lifting transfer unit to lower in time, enabling special materials to quickly move from the mobile transfer part above the special material storage box to the storage box, and then move to the explosion-proof box or special storage box through the screw slide table part. The entire movement process is completed by electric components, improving the transfer efficiency and material stability.

[0032] 5. The present invention enables the storage of special materials with small volume, large quantity, and various types through the internal storage track layer of the stackable storage box. At the same time, due to the outer cross-shaped storage track and the cross-shaped transport track that can be lifted and joined in the middle, the special storage box can quickly switch between storage and retrieval, greatly improving the work efficiency and space utilization rate.

[0033] 6. The present invention passes through a specially made alloy transfer frame, on which three rectangular openings exactly match the specially made rectangular transport groove. Under the action of the first electric push rod and the plug board stepping motor, when the bottom plug board is opened by the plug board stepping motor, the material can smoothly slide from the bottom plug board to the bottom plate of the rectangular transport groove, and the first electric push rod is responsible for transporting the material up and down. Similarly, due to the slope design and triangular slot on one side of the bottom plug board, when the bottom plug board is closed by the plug board stepping motor, the material can also be smoothly shoveled from the bottom plate to the bottom plug board for retrieval. This method is convenient and efficient, and the components cooperate with each other. Both the storage and retrieval processes can be used, with high component utilization rate and improved work efficiency.

[0034] 7. Compared with the prior art, the lifting housing installed on the main and auxiliary boxes in the present invention has different adaptations to the main and auxiliary boxes. It can move up and down on the surface of the transport box through a gear-rack mechanism. When it moves to the top, it can be fixed through the top plugging unit above it to achieve enclosed transportation of the upper open space of the transport box. When it moves to the bottom, it can be pushed out by the sixth electric push rod below to contact the ground, thereby raising the overall height of the transport box. At the same time, after the main transport box is propped up by the electric push rod, each auxiliary transport box can be automatically spliced with it through movement and form a main-auxiliary transport box cluster combination similar to "4 + 1", "2 + 1", "1 + 1", greatly improving the adaptability of the device in the tunnel. Whether it is in a wide place or a narrow place, a high place or a low place, transportation can be carried out, greatly expanding the application range of the device.

Three first electric push rods 1105 are arranged at the corresponding positions of the lower middle part of the cross plate 1103b of the lifting platform and the rectangular transport grooves 1104. The main body of the first electric push rod 1105 is fixedly installed on the lower surface of the cross plate 1103b of the lifting platform, and its output end passes through the upper surface of the cross plate 1103b of the lifting platform and is fixedly connected to the bottom plate inside the rectangular transport groove 1104. A fixed rectangular track is arranged inside the rectangular transport groove 1104, and the bottom plate can move up and down inside the rectangular transport groove 1104 along the fixed rectangular track under the push of the first electric push rod 1105. The purpose of setting this structure is that when the mobile transfer part 4000 comes above the lifting and transfer unit 1100 through the transfer track part 3000, the cross plate 1103b of the lifting platform is lifted to the position of the storage top plate 1004 by the electric lifting trolley 1102, and the three storage grooves of the mobile transfer part 4000 are aligned with the three rectangular transport grooves 1104. At this time, the top of the rectangular transport groove 1104 contacts the bottom of the alloy transfer frame 4001. After opening the bottom plug plate 4002, a closed rectangular vertical channel can be formed. The bottom plate of the rectangular transport groove 1104 is pushed up by the first electric push rod 1105 to the lower part of the bottom plug plate 4002. After opening the bottom plug plate 4002, the material falls on the bottom plate, and then the bottom plate is lowered to the bottom of the rectangular transport groove 1104. Then, the cross plate 1103b of the lifting platform is lowered to the inside of the storage box by the electric lifting trolley 1102, and the material inside the rectangular transport groove 1104 is transferred by the lead screw slide part 5000. When taking out the material, only need to form a closed rectangular channel between the rectangular transport groove 1104 and the inside of the alloy transfer frame 4001 in the same way. When the bottom plate of the rectangular transport groove 1104 is pushed up by the first electric push rod 1105 to the lower part of the bottom plug plate 4002, only need to close the bottom plug plate 4002, and the material can be automatically shoveled up by the slope structure of the bottom plug plate 4002 for transfer.Compared with the prior art, in the present invention, the lifting electric trolley 1102 controls the lifting and transfer unit 1100 to lift inside the storage box, enabling the storage box to quickly switch between the sealed and open states, ensuring the stability and controllability of the material storage environment. The first electric push rod 1105 at the bottom of the lifting platform cross plate 1103b can push the bottom plate of the rectangular transport groove 1104 up and down. When it moves below the bottom plug board 4002, since the top of the rectangular transport groove 1104 has already contacted the bottom of the alloy transfer frame 4001 at this time, that is, a closed rectangular vertical channel can be formed after opening the bottom plug board 4002. Then, by opening the bottom plug board 4002, the material can smoothly fall onto the bottom plate, and then the bottom plate is lowered to store the material in the rectangular transport groove 1104. Then, the rectangular transport groove 1104 transports the material to the inside of the storage box for transfer and storage. This method of transporting special materials is relatively stable, and the whole process is completed by electric components, reducing human factor interference and improving efficiency.

[0071] From Figure 6As shown in the figure, the general structure of the secondary transport box part 2000 is the same as that of the main transport box part 1000. The difference is that the position corresponding to the T-shaped connecting rod 1005b on the outer side of the storage shell 1003 at the bottom is set as the T-shaped connecting rod socket 2002. A splicing track support rod socket 2004 is vertically arranged on the storage shell 1003 between the two T-shaped connecting rod sockets 2002, and the splicing track support rod socket 2004 corresponds to the cross-shaped transfer double track 3001 in position; the T-shaped connecting rod socket 2002 is provided with a slot from top to bottom, and at the same time, a socket rectangular opening 2002b is provided from right to left in the upper half. An inner slot 2002a is provided between it and the storage shell 1003, and a second electric push rod 2003 is provided at its bottom; the purpose of setting this structure is that when starting to connect the secondary transport box part 2000 with the main transport box part 1000, the T-shaped connecting rod 1005b is inserted through the slot at the upper end of the T-shaped connecting rod socket 2002. When encountering a bumpy road section, the second electric push rod 2003 can push the spring support 1005c at the bottom of the T-shaped connecting rod 1005b. The eight sets of connecting rod mechanisms of the four secondary transport box parts 2000 on the four sides of the main transport box part 1000 jointly lift the main transport box part 1000 to a certain height. When the main transport box part 1000 bumps, because there are eight bottom springs as supports, the main transport box can effectively reduce vibration.Compared with the prior art, the present invention realizes the quick connection and disengagement between the main and auxiliary transport boxes through the combination of a detachable T-shaped connecting rod and a socket, etc. When connecting the main and auxiliary transport boxes, the gear on it can be controlled by the fourth stepping motor 7005 to rotate on the rack track 4002a of the outer shell lifting track 7003, thereby driving the lifting housing 7001 to descend. When it descends to an appropriate height, the sixth electric push rod 7002 can be controlled to push out the push plate downward. When the push plate touches the ground, the support of the entire transport box is switched from the universal wheel 1002 to the push plate. Continuing to extend the push plate can realize the lifting of the transport box. After lifting the main transport box part 1000, control the movement of the auxiliary transport box part 2000 until the T-shaped connecting rod socket 2002 is directly below the T-shaped connecting rod 1005b. Here, the T-shaped connecting rod 1005b can also be pushed out or retracted by the connecting rod electric push rod 1005a to accelerate the docking. Then lower the main transport box part 1000, insert the T-shaped connecting rod 1005b into the T-shaped connecting rod socket 2002, and at the same time lower the splicing track support rod 3003 and insert it into the splicing track support rod socket 2004 to complete the connection; when disengaging, only need to push up the T-shaped connecting rod 1005b by the second electric push rod 2003 at the bottom of the T-shaped connecting rod socket 2002 until it disengages from the socket to complete the disengagement. The number of auxiliary transport boxes can also be increased according to actual needs. Only need to add additional T-shaped connecting rod combinations between the auxiliary transport boxes to complete the connection, forming a tunnel engineering special material transport device cluster similar to a nine-square grid, greatly improving the special material transport volume, and at the same time adapting to the transport needs of narrow or wide roads to improve the adaptability of the device; at the same time, because a spring support 1005c is provided at the bottom of the T-shaped connecting rod 1005b and a second electric push rod 2003 is provided at the bottom of the T-shaped connecting rod socket 2002, when the second electric push rods 2003 of the auxiliary transport box parts 2000 on all four sides push up the T-shaped connecting rod 1005b together, under the action of the spring support 1005c, the main transport box part 1000 can be lifted and buffered, effectively adapting to bumpy sections and improving the stability of the device.

[0072] As Figure 13As shown in the figure, the transfer track part 3000 is mainly composed of a cross-shaped transfer double track 3001. The cross-shaped transfer double track 3001 is installed at the upper end of the storage top plate 1004 of the main transport box part 1000 and the auxiliary transport box part 2000. Splicing tracks 3002 are arranged at the ends of the four sides of the cross-shaped transfer double track 3001 on the main transport box part 1000. The splicing tracks 3002 are installed on the extended lifting housing part 7000 on the side close to the main transport box part 1000, and can be lifted and lowered together with the extended lifting housing part 7000. When it descends to the height of the cross-shaped transfer double track 3001 of the auxiliary transport box part 2000, it can be connected with it to form a complete track. Splicing track support rods 3003 are arranged at the lower part of the end of the splicing tracks 3002 close to the auxiliary transport box part 2000, and splicing track fixing plates 3002a are also arranged on both sides of its end. Two third electric push rods 3004 are arranged on both sides of the corresponding end of the cross-shaped transfer double track 3001 on the auxiliary transport box part 2000. The third electric push rods 3004 are installed at the upper end of the storage top plate 1004, and L-shaped baffles 3005 are arranged at their push rod ends; the purpose of setting this structure is that when connecting the transfer track part 3000 between the main and auxiliary transport boxes, first lower the lifting housing 7001 on the surface of the auxiliary transport box part 2000 to below its splicing track support rod socket 2004 so that it will not interfere with the insertion of the splicing track support rod 3003. Then lower the lifting housing 7001 on the surface of the main transport box part 1000, and the splicing track 3002 installed on it will also descend, and the splicing track support rod 3003 at the lower part of the end of the splicing track 3002 will be inserted into the splicing track support rod socket 2004. When track splicing is required, lower the entire main transport box part 1000 through the second electric push rod 2003 so that the splicing track 3002 descends to the docking position, that is, the height of the splicing track fixing plate 3002a is lower than that of the L-shaped baffle 3005. Push out the L-shaped baffle 3005 through the third electric push rod 3004 so that it covers the splicing track fixing plate 3002a. At this time, push the third electric push rod 3004 to make the splicing track fixing plate 3002a and the L-shaped baffle 3005 fit completely. Limit the lower splicing track fixing plate 3002a through the L-shaped baffle 3005. At the same time, push the entire main transport box part 1000 upward through the second electric push rod 2003 to make the L-shaped baffle 3005 fit tightly with the splicing track fixing plate 3002a, so that the entire main and auxiliary transport boxes and the splicing tracks on them are stably connected. At this time, the tracks on them form a complete passage;Compared with the prior art, the external transfer of the present invention is completed by an orbital group composed of a cross-shaped transfer double track 3001 and a splicing track 3002. The orbital group can be fixed and disengaged through the cooperation of a second electric push rod 2003, a third electric push rod 3004, an L-shaped baffle 3005, and a splicing track fixing plate 3002a. When in need of use, the track can be quickly connected, enabling the electric trolley to move the mobile transfer part 4000 between the transport boxes. When not in use, it can be quickly separated, without interfering with the overall transportation and the shock absorption of the main transport box, with high transfer efficiency, small space occupation, and strong adaptability.

[0073] consisting of Figure 7As shown, the lead screw slide table part 5000 is mainly supported by the lead screw slide table mounting seat 5001. The lead screw slide table mounting seat 5001 is installed on the alloy frame 1001 of this part of the storage box. A first stepping motor 5002a is provided at both ends of the lead screw slide table mounting seat 5001. The output ends of the two first stepping motors 5002a are connected to a horizontal first lead screw 5002b. A first slide table 5002c is provided on the first lead screw 5002b. A second stepping motor 5003a is provided on the first slide table 5002c. The output end of the second stepping motor 5003a is connected to a vertical second lead screw 5003b. A second slide table 5003c is provided on the second lead screw 5003b; A third stepping motor 5004a is provided on the second slide table 5003c. The output end of the third stepping motor 5004a is connected to a longitudinal third lead screw 5004b. A third slide table 5004c is provided on the third lead screw 5004b. Fourth electric push rods 5005 are provided at the upper ends on the left and right sides of the third slide table 5004c. The output ends of the fourth electric push rods 5005 are connected to a rotating motor 5006. The output end of the rotating motor 5006 is connected to an electric gripper 5007; The purpose of setting this structure is that when it is necessary to transfer the materials sent down by the lifting and transfer unit 1100, when the main transport box part 1000 is being transferred, first use a set of lead screw slide table gripper groups to grab and rotate to open the door of the explosion-proof box 1200 and move it to the rightmost end of the lead screw slide table part 5000. This set of lead screw slide table gripper groups includes a set of vertical first slide tables 5002c, and the second stepping motor 5003a, the second lead screw 5003b, the second slide table 5003c, the third stepping motor 5004a, the third lead screw 5004b, the third slide table 5004c, the fourth electric push rod 5005, the rotating motor 5006, and the electric gripper 5007 thereon. At this time, lower the lifting and transfer unit 1100. Drive the first slide table 5002c with the first stepping motor 5002a to bring the components thereon above the rectangular transport groove 1104. Adjust the longitudinal position of the third slide table 5004c thereon through the third stepping motor 5004a so that it is directly above the rectangular transport groove 1104. Control the second stepping motor 5003a to adjust the second slide table 5003c to a suitable height. At this time, push out the rotating motor 5006 through the fourth electric push rod 5005, then control the angle of rotation through the rotating motor 5006, and finally grab the materials through the electric gripper 5007. Move the lead screw slide table gripper group in the opposite way to make it leave the rectangular transport groove 1104 and transport the materials into the explosion-proof box 1200. After all the transportation is completed, close the explosion-proof box 1200 by moving the lead screw slide table gripper group.Compared with the prior art, the present invention realizes the three-dimensional movement of the clamping device through the designed screw rod slide table jaw group. At the same time, in cooperation with the timely lowering of the lifting and transfer unit 1100, special materials can be quickly moved from the mobile transfer part 4000 at the upper part of the storage box into the storage box, and then moved to the explosion-proof box 1200 or the special storage box 6004 through the screw rod slide table part 5000. The materials transported here are usually materials with specific shapes such as explosives. For example, powdery or liquid materials are usually stored in storage containers and then transported after being placed in them. For tubular explosives and cubic storage containers, the mechanism of the screw rod slide table jaw group can realize the transportation here. The whole movement process is completed by electric components, improving the transfer efficiency and material stability.

[0074] Consisting of Figure 8 , Figure 9As shown in the figure, the lifting storage part 6000 is mainly composed of three layers of storage track mounting plates 6001. The storage track mounting plates 6001 are installed at the bottom of the storage box of the auxiliary transport box part 2000. A cross-shaped storage track 6002 is provided thereon. An opening is provided at the cross-shaped intersection in the middle of the cross-shaped storage track 6002, and corresponding openings are also provided at the same position on the storage track mounting plate 6001; at the lower end of the middle part of the lowermost layer of storage track mounting plate 6001, a fifth electric push rod 6005 is provided. The output end of the fifth electric push rod 6005 is installed with a cross-shaped track mounting platform 6003a. The size of the cross-shaped track mounting platform 6003a just matches the size of the opening in the middle of the cross-shaped storage track 6002. A cross-shaped transport track 6003b is provided on the cross-shaped track mounting platform 6003a; an electric trolley is provided below the special storage box 6004, which can move on each track for storage and transportation. The track can be adjusted according to the actual size of the special storage box 6004 so that it can pass through at the corners and on the cross-shaped track.The purpose of setting this structure is that when internal storage of the auxiliary transport box part 2000 is required, an empty special storage box 6004 can be moved onto the cross-shaped transport track 6003b, and the cross-shaped track mounting platform 6003a can be lifted by the fifth electric push rod 6005 so that it enters the transfer range of the lead screw slide table part 5000. Then, in the same way as above by the lead screw slide table gripper group, that is, first, a group of lead screw slide table grippers grabs and rotates the door of the special storage box 6004 and moves it until it is fully opened. At this time, the lifting and transfer unit 1100 is lowered. The first stepping motor 5002a drives the first slide table 5002c with the components thereon to come above the rectangular transport groove 1104. The longitudinal position of the third slide table 5004c thereon is adjusted by the third stepping motor 5004a so that it is directly above the rectangular transport groove 1104. The second stepping motor 5003a is controlled to adjust the second slide table 5003c to a suitable height. At this time, the rotating motor 5006 is pushed out by the fourth electric push rod 5005, and then the rotation control angle is adjusted by the rotating motor 5006. Finally, the material is grabbed by the electric gripper 5007. The lead screw slide table gripper group is moved in the opposite way to leave the rectangular transport groove 1104 and transport the material into the special storage box 6004. After all the transportation is completed, the special storage box 6004 is closed by moving the lead screw slide table gripper group. This situation is only applicable when the transported material allows open transfer, such as explosives, detonators, and flammable solids. When the material is not suitable for open transfer, such as radioactive substances, toxic and harmful substances, etc., the step of opening the special storage box 6004 is not required here. Instead, a special storage box 6004 already loaded with materials is stored in the alloy transfer frame 4001, transported to the rectangular transport groove 1104 through the internal lifting channel, and then the entire special storage box 6004 is directly grabbed by moving the lead screw slide table gripper group and placed on the cross-shaped transport track 6003b for internal storage. After storage, the cross-shaped track mounting platform 6003a is lowered by the fifth electric push rod 6005 to be flush with the first-layer storage track mounting plate 6001. The special storage box 6004 enters the interior of the storage box through the connected cross-shaped storage track 6002. Then, another empty special storage box 6004 is moved onto the cross-shaped transport track 6003b, and the above operations are repeated for re-storage or retrieval. Compared with the prior art, the present invention enables the storage of special materials with small volume, large quantity, and various types through the stackable internal storage track layer of the storage box. At the same time, due to the provision of the outer cross-shaped storage track 6002 and the cooperated cross-shaped transport track 6003b that can be lifted and joined in the middle, the special storage box 6004 can quickly switch between storage and retrieval, greatly improving the work efficiency and space utilization rate.

[0075] From Figure 10As shown in the figure, the mobile transfer part 4000 is mainly composed of an alloy transfer frame 4001. There are three rectangular openings in the middle of the alloy transfer frame 4001, and their sizes and positions match those of the rectangular transport tank 1104. Electric trolleys are arranged below the frame between every two of the three rectangular openings and can move on the transfer track part 3000. A triangular slot 4001a is arranged on the left side inside the rectangular opening, and a plugboard rectangular opening 4001b is arranged at the corresponding position on the right side. The bottom plugboard 4002 can be inserted into the plugboard rectangular opening 4001b and slide therein. One end of the bottom plugboard 4002 is set to be a slope, and the inclination degree matches that of the triangular slot 4001a, so that the bottom plugboard 4002 can fit better when inserted into the triangular slot 4001a; a rack track 4002a is arranged at the left end of the bottom plugboard 4002, and a plugboard stepping motor 4003 is installed at the position of the alloy transfer frame 4001 close to the rack track 4002a. The output shaft of the plugboard stepping motor 4003 is connected with a gear, and the gear meshes with the rack track 4002a. The plugboard stepping motor 4003 can drive the gear to rotate on the rack track, thereby driving the opening and closing of the bottom plugboard 4002. The purpose of setting this structure is that when used to store special materials, the bottom plugboard 4002 is controlled by the plugboard stepping motor 4003 to be inserted into the triangular slot 4001a, and the materials can be stably loaded into the three rectangular openings of the alloy transfer frame 4001. When the mobile transfer part 4000 moves above the lifting transfer unit 1100 on the transfer track part 3000, when the first electric push rod 1105 pushes the bottom plate of the rectangular transport tank 1104 below the bottom plugboard 4002, the bottom plugboard 4002 is opened by the plugboard stepping motor 4003, and the materials slide onto the bottom plate through the slope at the front end of the plugboard. The first electric push rod 1105 is lowered, and the materials are transferred to the lifting transfer unit 1100 at this time. Compared with the prior art, in the present invention, through the specially made alloy transfer frame 4001, the three rectangular openings on it exactly match the specially made rectangular transport tank 1104. Under the action of the first electric push rod 1105 and the plugboard stepping motor 4003, the materials can smoothly slide from the bottom plugboard 4002 to the bottom plate of the rectangular transport tank 1104. Similarly, because of the slope design on one side of the bottom plugboard 4002 and the cooperation with the triangular slot 4001a, the materials can also be smoothly shoveled from the bottom plate into the bottom plugboard 4002 for taking out. This method is convenient and efficient, and the components cooperate with each other. The storage and retrieval processes can both be used, the utilization rate of the components is high, and the working efficiency is also improved.

[0076] The explosion-proof box 1200 is used to store inflammable and explosive substances, so it is located in the main transport box part 1000 with middle shock absorption, while the special storage box 6004 can be set as a storage box for toxic and harmful substances, a storage box for radioactive substances, etc. according to needs.

[0077] by Figure 11, Figure 12 As shown in Figure 12 , the extended lifting housing part 7000 includes a lifting housing 7001 installed on the surfaces of the main transportation box part 1000 and the secondary transportation box part 2000, and also includes a top plug-in unit 7100 installed on the top baffle 1006. The inner wall of the lifting housing 7001 can fit well with the storage housing 1003. When the lifting housing 7001 rises to the top, it can completely enclose the upper part of the transportation box to form a sealed space during transportation. The bottom of the lifting housing 7001 is provided with an outward-extending housing bottom plate 7001a, and the four corners of the housing bottom plate 7001a are provided with sixth electric push rods 7002. On the four sides of the lifting housing 7001 installed on the surface of the main transportation box part 1000, there are two vertical first rectangular slots 7001b, and their positions correspond to the connecting rod electric push rods 1005a. The bottom of the first rectangular slot 7001b is a vertical second rectangular opening 7001d. That is, the upper half here is not completely penetrated due to the slotting, so it can be used as a baffle for the closed box, while the lower part is completely penetrated due to the opening, so the connecting rod electric push rods 1005 installed on the main transportation box part 1000 can pass through. The structure of the lifting housing 7001 installed on the surface of the secondary transportation box part 2000 is similar to that on the main transportation box part 1000, except that the slotting and opening structure on the four sides is replaced on the surface of the T-shaped connecting rod socket 2002. Since the inner slot 2002a is provided on the T-shaped connecting rod socket 2002, the baffle formed by the first rectangular slot 7001b can enter the inner slot 2002a, so that the entire housing can be lowered to a lower height, and thus the height adjustment of the secondary transportation box part 2000 can be increased. At the positions near the top on the four sides of the lifting housing 7001, there are first rectangular openings 7001c, and the size of the first rectangular openings 7001c can match the extended fixed plug-in plates 7105.

[0078] On the upper surface of the lifting housing 7001 at the gaps left by two adjacent extended fixed plug-in plates 7105, there are vertical housing lifting tracks 7003. On the housing lifting tracks 7003, there are rack tracks 4002a. The fourth stepping motor mounting base 7004 is installed on the corresponding top baffle 1006, and a fourth stepping motor 7005 is provided thereon. The fourth stepping motor 7005 meshes with the rack tracks on the housing lifting tracks 7003 through the gears thereon, thereby controlling the up and down movement of the lifting housing 7001.

[0079] The top plugboard unit 7100 includes a seventh electric push rod 7101 installed in the middle of the top baffle 1006. A plugboard power plate 7102 is connected to the seventh electric push rod 7101. The plugboard power plate 7102 is hingedly connected to the extended fixed plugboards 7105 on all four sides through plugboard connecting rods 7103. The bottom of the extended fixed plugboard 7105 is installed on the plugboard track 7104 through pulleys. The purpose of setting this structure is that when it is necessary to lift the transport box, the fourth stepping motor 7005 can be used to control the gear on it to rotate on the rack track of the housing lifting track 7003, thereby driving the lifting housing 7001 to descend. When it descends to an appropriate height, the lifting housing 7001 and the transport box are fixed as a whole at this time. The sixth electric push rod 7002 can be controlled to push out the push plate downward. When the push plate touches the ground, the self-weight of the entire transport box is borne jointly by the universal wheels 1002 and the push plate at this time. Continue to extend the push plate, and at this time the self-weight of the transport box is borne entirely by the push plate, that is, it is fixed on the ground. Continue to push out the push rod. Since the sixth electric push rod 7002 is fixedly installed on the housing bottom plate 7001a and its main body is relatively fixed to the lifting housing 7001 and the transport box, when the push plate end moves downward relative to its main body, the transport box can be lifted. This can be used for automatically splicing the main and auxiliary transport boxes. For example, after raising the main transport box part 1000, control the auxiliary transport box to move until the T-shaped link socket 2002 is directly below the T-shaped link 1005b. Here, the T-shaped link 1005b can also be pushed out or retracted by the link electric push rod 1005a to accelerate the docking. Then lower the main transport box part 1000. The T-shaped link 1005b is inserted into the T-shaped link socket 2002, and the splicing can be completed. The splicing here can be carried out simultaneously on all four sides, and finally a "4 + 1" main and auxiliary transport box cluster is formed, which can pass through the wide part of the tunnel. When it is necessary to pass through the narrow part of the tunnel, it can be spliced into a straight-line "2 + 1" main and auxiliary transport box cluster in the same way. If the tunnel is further narrowed, it can also be spliced into a "1 + 1" main and auxiliary transport box group. When there is more than one auxiliary transport box spliced with the main transport box, the lifting height of the main transport box can reach the combined push-out height of the sixth electric push rod 7002 and the second electric push rod 2003. The last case is that the tunnel is so narrow that only one main transport box part 1000 can pass through. Here, the sixth electric push rod 7002 on it can still be used to push out and then lift the height of the box body, greatly improving the adaptability of the device to the tunnel;When the box needs to be transported, the lifting mechanism of the fourth-step motor 7005 can be used to lift the lifting housing 7001 to the highest position. At this time, the lifting housing 7001 completely covers the open part of the upper part of the transport box. At the same time, the height of its first rectangular opening 7001c corresponds to that of the extended fixed plug board 7105. The plug board power plate 7102 is pushed out by the seventh electric push rod 7101. Under the action of the plug board connecting rod 7103, the extended fixed plug board 7105 slides outwards on the plug board track 7104 and then inserts into the first rectangular opening 7001c, which can not only fix the lifting housing 7001, but also block to a certain extent the splicing part between the upper part of the lifting housing 7001 and the transport box, preventing the collapse and falling objects in the tunnel from affecting the inside of the box and improving the stability. Compared with the prior art, the lifting housing 7001 installed on the main and auxiliary boxes in the present invention has different adaptations to the main and auxiliary boxes. It can move up and down on the surface of the transport box through the gear-rack mechanism. When it moves to the top, it can be fixed by the top plug board unit 7100 above it to realize closed transportation of the open space in the upper part of the transport box. When it moves to the bottom, the sixth electric push rod 7002 below can be pushed out to contact the ground, thereby lifting the overall height of the transport box. At the same time, after the main transport box is supported by this electric push rod, each auxiliary transport box can be automatically spliced with it by moving, and a main and auxiliary transport box cluster combination similar to 4+1, 2+1, 1+1 is formed, greatly improving the adaptability of the device in the tunnel. Whether it is a wide place, a narrow place, a high place or a low place, transportation can be carried out, greatly expanding the application range of the device.;

[0080] A special material transportation method for tunnel engineering, see Figures 1 - 13 , including:

[0081] Combined assembly of the device: When starting to connect the secondary transport box part 2000 and the main transport box part 1000, the gear on it can be controlled by the fourth stepping motor 7005 to rotate on the rack track of the outer shell lifting track 7003, thereby driving the lifting housing 7001 to descend. When it descends to an appropriate height, the push plate can be pushed downward by controlling the sixth electric push rod 7002. When the push plate touches the ground, the support of the entire transport box is switched from the universal wheels 1002 to the push plate. Continuing to extend the push plate can achieve the rise of the transport box. After raising the main transport box part 1000, control the movement of the secondary transport box until the T-shaped link socket 2002 is directly below the T-shaped link 1005b. Here, the T-shaped link 1005b can also be pushed out or retracted by the link electric push rod 1005a to accelerate docking. Then lower the main transport box part 1000, insert the T-shaped link 1005b into the T-shaped link socket 2002, and at the same time, the splicing track support rod 3003 descends and inserts into the splicing track support rod socket 2004 to complete the splicing. Here, the splicing can be carried out simultaneously on all four sides, finally forming a 4 + 1 main and secondary transport box cluster, which can pass through the wide part of the tunnel. When passing through the narrow part of the tunnel, it can be spliced into a 2 + 1 main and secondary transport box cluster in a straight line in the same way. If the tunnel is further narrowed, it can also be spliced into a 1 + 1 main and secondary transport box group. When more than one secondary transport box is spliced with the main transport box, the rising height of the transport box of the main transport box part 1000 can reach the combined pushing height of the sixth electric push rod 7002 and the second electric push rod 2003. The last case is that the tunnel is so narrow that only one main transport box part 1000 can pass through. Here, the height of the box body can still be lifted by pushing out the sixth electric push rod 7002 on it; when encountering a bumpy road section, the second electric push rod 2003 can be used to push the spring support 1005c at the bottom of the T-shaped link 1005b. Because there are eight bottom springs as supports, the main transport box can effectively reduce vibration;

[0082] Splicing of the transfer track: When connecting the transfer track part 3000 between the main and secondary transport boxes, insert the splicing track support rod 3003 at the lower end of the end of the splicing track 3002 into the splicing track support rod socket 2004. When track splicing is required, control the lowering of the extended lifting outer shell 7001 by the fourth stepping motor 7005 so that the splicing track 3002 descends to the docking position, that is, the height of the splicing track fixing plate 3002a is lower than the L-shaped baffle 3005. At this time, push out the L-shaped baffle 3005 by the third electric push rod 3004 so that it covers the splicing track fixing plate 3002a, and push the third electric push rod 3004 to make the splicing track fixing plate 3002a and the L-shaped baffle 3005 fit completely. Through the pressure at the upper and lower ends of the splicing track fixing plate 3002a, the entire main and secondary transport boxes and the splicing track on them are stably connected, and at this time, the tracks on them form a complete passage;

[0083] Transfer between transport boxes: When used for storing special materials, the mobile transfer part 4000 is located on the cross-shaped transfer double track 3001 at the outermost side of the secondary transport box part 2000. By controlling the bottom plug board 4002 to insert into the triangular slot 4001a through the plug board stepping motor 4003, the materials can be stably loaded into the three rectangular openings of the alloy transfer frame 4001. When the mobile transfer part 4000 moves above the lifting transfer unit 1100 on the transfer track part 3000, the first electric push rod 1105 pushes the bottom plate of the rectangular transport groove 1104 below the bottom plug board 4002. By opening the bottom plug board 4002 through the plug board stepping motor 4003, the materials slide onto the bottom plate of the rectangular transport groove 1104 through the front slope of the plug board. Lower the first electric push rod 1105, and the materials are transferred to the lifting transfer unit 1100 at this time;

[0084] Transfer between the storage box and the outside: When the mobile transfer part 4000 comes above the lifting transfer unit 1100 through the transfer track part 3000, the lifting platform cross plate 1103b is lifted to the position of the storage top plate 1004 by the lifting electric trolley 1102. Align the three storage grooves of the mobile transfer part 4000 with the three rectangular transport grooves 1104. Push up the bottom plate of the rectangular transport groove 1104 below the bottom plug board 4002 through the first electric push rod 1105, open the bottom plug board 4002, the materials fall on the bottom plate, then lower the bottom plate to the bottom of the rectangular transport groove 1104, and then lower the entire lifting transfer unit 1100 to the inside of the storage box by the lifting electric trolley 1102. The materials inside the rectangular transport groove 1104 are transferred by the lead screw slide table part 5000;

[0085] Transfer inside the main storage box: When it is necessary to transfer the materials sent down by the lifting transfer unit 1100, when carrying out the transfer of the main transport box part 1000, first use a set of lead screw slide table jaw groups to clamp, rotate and open the box door of the explosion-proof box 1200 and move it to the rightmost end of the lead screw slide table part 5000. At this time, lower the lifting transfer unit 1100. Drive the first slide table 5002c with the components on it to above the rectangular transport groove 1104 through the first stepping motor 5002a. Adjust the longitudinal position of the third slide table 5004c on it through the third stepping motor 5004a so that it is directly above the rectangular transport groove 1104. At this time, control the second stepping motor 5003a to adjust the second slide table 5003c to a suitable height. Push out the rotary motor 5006 through the fourth electric push rod 5005, then control the angle through the rotary motor 5006, and finally clamp the materials with the electric jaw 5007. Move the lead screw slide table jaw group in the opposite way to make it leave the rectangular transport groove 1104 and transport the materials into the explosion-proof box 1200. After all the transportation is completed, close the explosion-proof box 1200 through the moving lead screw slide table jaw group;

[0086] Internal transfer within the secondary storage box: When storing inside the secondary transport box part 2000, an empty special storage box 6004 can be moved onto the cross-shaped transport track 6003b. The cross-shaped track mounting platform 6003a is lifted by the fifth electric push rod 6005 so that it enters the transfer range of the lead screw slide table part 5000. Then, the material is transferred into the special storage box 6004 in the same way as above by the lead screw slide table jaw group. After storage, the cross-shaped track mounting platform 6003a is lowered by the fifth electric push rod 6005 until it is flush with the first-layer storage track mounting plate 6001. The special storage box 6004 enters the interior of the storage box through the connected cross-shaped storage track 6002. Then, another empty special storage box 6004 is moved onto the cross-shaped transport track 6003b, and the above operations are repeated for further storage or retrieval.

[0087] Closed transport of the device: When transporting the box body, the fourth step motor 7005 can be controlled to drive the gear on it to rotate on the outer shell lifting track 7003, thereby lifting the lifting housing 7001 to the highest position. At this time, the upper open part of the transport box is completely blocked by the lifting housing 7001. At the same time, the height of its first rectangular opening 7001c corresponds to that of the extended fixed plug board 7105. The plug board power plate 7102 is pushed out by the seventh electric push rod 7101. Under the action of the plug board connecting rod 7103, the extended fixed plug board 7105 slides outwards on the plug board track 7104 and then inserts into the first rectangular opening 7001c, which can not only fix the lifting housing 7001 but also block a certain part of the splicing part above the lifting housing 7001 and the transport box to prevent the collapse and falling objects in the tunnel from affecting the interior of the box body.

[0088] The above is only the specific implementation manner in the present invention, but the protection scope of the present invention is not limited thereto. Any transformation or replacement that can be understood by those familiar with the technology within the technical scope disclosed by the present invention should be covered within the scope of the present invention.
