Description

Technical Field

[0001] The invention relates to the technical field of construction material transportation, and in particular to an integrated platform for transporting support and lining materials for underground cavern construction in a hydropower station. Background Art

[0002] The underground cavern of a hydropower station is an engineering building buried in the ground, and is a form of human use of underground space. When excavating the underground cavern of a hydropower station, special support structures and lining materials are needed to protect the inner wall of the underground cavern and reduce the risk of rocks falling and injuring construction workers. When laying the support structure and lining materials of the underground cavern of a hydropower station, it is necessary to transport the materials that make up the support structure and lining materials (including but not limited to: steel mesh and other construction materials). At this time, a special transportation platform structure is needed to save manpower and improve the degree of intelligence and mechanization when transporting construction materials.

[0003] The existing Chinese patent application with publication number CN118493531A discloses a board cutting robot arm for wood processing that can collect wood chips, including a robot arm body, a power component installed on the robot arm body, a linkage structure installed on the power component, a collection structure arranged on the linkage structure, and the linkage structure and the collection structure cooperate with each other to collect wood chips, a feeding structure installed on the collection structure, a connecting structure for limiting the feeding structure installed on the linkage structure, and an elastic structure arranged inside the connecting structure; this invention can transport the grasped and fixed board by means of grasping by the robot arm.

[0004] The existing Chinese patent with authorization announcement number CN114718617B discloses a tunnel support anchor conveying robot, including a support platform, a moving mechanism is installed on the support platform, a working box is fixedly connected to the top of the support platform, two anchor storage ports are opened on the top of the working box, and an anchor storage and conveying mechanism, an anchor transfer mechanism and an anchor output mechanism are arranged in the working box from left to right. The anchor storage and conveying mechanism is arranged corresponding to the anchor transfer mechanism, and the anchor transfer mechanism is connected to the anchor output mechanism in a transmission manner. The two anchor storage ports are located above the anchor storage and conveying mechanism and are arranged corresponding to the anchor storage and conveying mechanism. A conveying port is opened on the outer wall of the working box, a manipulator is installed on the working box, and the anchor output mechanism and the manipulator are both arranged corresponding to the conveying port. The invention realizes the storage, conveying and installation of anchors for tunnel construction, greatly reduces the workload of construction personnel, and improves construction efficiency.

[0005] However, the conveying platform has the following defects when used:

[0006] 1. When the existing conveying platform is used to transport construction materials (support materials and lining materials) in underground caverns, in order to improve the efficiency of transportation, it generally adopts the method of mechanical arm grabbing and device movement to realize the automatic transportation operation of construction materials. However, in the operation of the traditional scheme, the transported construction materials are generally transported in a horizontal manner. When the transported construction materials are then installed, the staff needs to spend a lot of physical strength and time to flip and adjust the installation position of the construction materials, resulting in low efficiency in the construction of the underground cavern support structure;

[0007] 2. When the existing conveying platform is conveying the plates for underground cavern support, in order to adjust the position of the construction materials, it is necessary to drive the construction materials to rotate. At this time, the rotational force that drives the construction materials to rotate and adjust the materials is likely to cause the grasped construction materials to shake or even fall, thereby affecting the safety of conveying the construction materials.

[0044] The present invention also provides a method for using the integrated platform for supporting and conveying lining materials for underground cavern construction of a hydropower station, comprising the following steps:

[0045] S1. The integrated transport platform is suitable for underground cavern excavation support and concrete lining construction stages, which can greatly reduce the input of construction personnel. When transporting the lining support components of support materials, steel bars, and formwork, the lining support components are first grasped and fixed by the lifting and grabbing components. At this time, the design of the internal parts of the lifting and grabbing components makes the lining support components more firm and stable when grasping and fixing, effectively reducing the risk of lining support components falling off or even falling during transportation;

[0046] S2. During the actual transportation of the lining support components, the oil cylinder flip assembly, steering assembly and vertical rotation assembly drive the grabbed lining support components to rotate and move at multiple angles to meet the different installation and laying requirements of the grabbed and fixed lining support components;

[0047] S3. During the construction of lining concrete reinforcement, the lifting and grabbing components absorb and fix the lining support components, effectively reducing the amount of scaffolding erection and safety risks.

[0048] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0049] 1. In the integrated platform for supporting construction and conveying lining materials for underground caverns of hydropower stations, when transporting and constructing construction materials for underground caverns, the hydraulic cylinder can be used to drive the movable oil rod at the output end to telescopically move, and the steering motor can be used to drive the steering mechanical arm at the output end to rotate, so as to change the direction of the fixed lining support components (towards the side, bottom and top of the underground cavern), thereby ensuring that the subsequent construction of the lining support components is more convenient and can effectively improve the efficiency of the construction of the lining support components. At the same time, when the lining support components are constructed on the side of the underground cavern, the operating hydraulic cylinder and steering motor can cooperate with the lifting cylinder to drive the lining support components to lift and move, automatically realizing the construction of lining support components at various heights of the underground cavern, effectively reducing the physical strength and time consumption of the staff;

[0050] 2. In the integrated platform for supporting construction and conveying lining materials in the underground cavern of a hydropower station, during the construction of the lining support components, it is necessary to adjust the installation angle of the lining support components. At this time, the DC motor can be started to operate, and the vertical rotating rod can be driven to rotate through the gear meshing connection to change the construction angle of the lining support components. At the same time, when the lining support components are rotated, the guide arm and the sliding seat connected to the top of the bottom connecting plate can move on the inner side of the arc frame, thereby ensuring the stability of the lining support components during angle adjustment, and preventing the vertical rotating rod from bending or even breaking due to the centrifugal force and gravity generated during rotation;

[0051] 3. In the integrated platform for supporting and conveying lining materials for underground cavern construction of hydropower stations, when conveying the supporting structure (lining support member) for excavating underground caverns, the edge of the lining support member can be clamped and adsorbed by a clamping block and a vacuum suction cup on the middle part of the lining support member, so as to complete the stable and firm grasping and fixing of the lining support member, and ensure that the lining support member will not shake or even fall off due to the rotational force generated by the rotation or flipping when rotating and flipping for subsequent multi-angle construction, thereby ensuring the safety of the lining support member during transportation and construction;

[0052] 4. In the integrated platform for supporting construction and conveying lining materials for underground caverns of hydropower stations, the transportation and construction directions of lining support components are adjusted. The movable side mounting arm and steering mechanical arm can be operated independently to achieve multi-angle adjustment operations. At the same time, when the two are moving separately, the steering mechanical arm can rotate close to the inner wall of the side mounting arm. On the one hand, it ensures that the rotation of the two will not be damaged or conflicted. On the other hand, it can increase the contact area of ​​the steering mechanical arm rotating on the inner wall of the side mounting arm, which is not easy to cause damage or even breakage of the output end of the steering motor;

[0053] 5. In the integrated platform for supporting and conveying lining materials for construction of underground caverns of hydropower stations, when the clamped and fixed lining support components are conveyed and installed, if the lining support components have a tendency to slide or even fall off, the force of the sliding of the lining support components will drive the threaded rods and the pressing blocks of the threaded connections to operate, so that the pressing blocks have a tendency to move downward, further reinforcing the lining support components that are about to slide (pressing them down and fixing them), thereby reducing the risk of the lining support components falling off during installation and transportation.

[0085] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0086] See also Figure 1-Figure 15 The integrated platform for supporting and conveying lining materials for construction of underground caverns of hydropower stations comprises a conveying base 10, an integrated grabbing and conveying mechanism 20, a lining support member 30 and a turnover assembly 40. A plurality of sets of universal wheels 100 are installed at the angle at the bottom of the conveying base 10. The turnover assembly 40 is installed on the top of the conveying base 10. The integrated grabbing and conveying mechanism 20 is installed on the top of the turnover assembly 40. The lining support member 30 is grabbed and adsorbed on the inner side of the integrated grabbing and conveying mechanism 20, and the lining support member 30 is conveyed to the inside of the underground cavern. Among them, the integrated grabbing and conveying mechanism 20 includes a cylinder flip assembly 50, which is installed on the top of the conveying base 10, and a steering assembly 60 is installed on the inside, and the steering assembly 60 and the cylinder flip assembly 50 are movably connected; and a vertical rotation assembly 70, which is installed inside the steering assembly 60 and extends to the bottom of the steering assembly 60, and lifting grabbing assemblies 80 are installed on both sides of the bottom of the vertical rotation assembly 70, and the inner side of the lifting grabbing assembly 80 grabs and fixes the lining support member 30.

[0087] The above working principle: when the lining support member 30 for underground cavern construction is transported, the lifting and grabbing assembly 80 can be lifted and moved, and the lining support member 30 can be grabbed and fixed. After that, the lining support member 30 that is grabbed and adsorbed can be automatically moved to the corresponding position in the underground cavern by moving the universal wheel 100, and the automatic transportation operation of the lining support member 30 is completed. When transporting and building the lining support member 30, the oil cylinder flip assembly 50 and the steering assembly 60 can be started respectively to operate, adjust the position of the lining support member 30 for construction, and improve the construction efficiency and effect of the underground cavern support structure formed by the lining support member 30. At the same time, when the lining support member 30 is actually built, the vertical rotation assembly 70 can drive the lining support member 30 that is grabbed and adsorbed to rotate, so as to adjust the angle of the lining support member 30 for construction, and reduce the physical strength and time consumption of the staff when building the lining support member 30.

[0100] Specific reference Fig.11 and Fig.12A guide arm 7051 is installed on the top of the bottom connecting plate 705, and the guide arm 7051 is located on the side of the vertical rotating rod 704, and the structural shape is "L" shape, wherein a sliding seat 7052 is installed at the bottom of the guide arm 7051, and the upper and lower sides of the sliding seat 7052 protrude outward and form a protruding block 7053, and the sliding seat 7052 is slidably connected to the inner side of the arc frame 7054, and wherein an arc groove 7055 is opened inside the arc frame 7054, and the arc groove 7055 and the protruding block 7053 are slidably connected, and the arc frame 7054 is installed on the outer side of the steering mechanical arm 602.

[0101] In the integrated platform for supporting and conveying lining materials for underground cavern construction of a hydropower station of the present invention, when the bottom connecting plate 705 rotates, the guide arm 7051 installed on the top thereof can drive the sliding seat 7052 installed on the side thereof to rotate (inside the arc frame 7054). At this time, the design of the movable connection between the sliding seat 7052 and the arc frame 7054 can ensure the stability of the bottom connecting plate 705 during rotation. At the same time, the protruding block 7053 can be synchronously moved inside the arc groove 7055, which can further improve the safety of the bottom connecting plate 705 during turning.

[0102] Specific reference Fig.11 and Fig.13 The lifting and grabbing assembly 80 includes a slide bar 801, which is mounted on both sides of the bottom of the longitudinal beam plate 7061 and is threadedly connected with a mounting portion 802 on the outer side, and the mounting portion 802 is mounted on both sides of the top of the longitudinal beam plate 7061, wherein a limit block 8011 is mounted at the bottom of the slide bar 801; a sliding support 803, which is slidably connected to multiple groups of slide bars 801 and is located below the longitudinal beam plate 7061, and the top center of the sliding support 803 is connected to the output end of the lifting cylinder 804, wherein the lifting cylinder 804 is mounted at the center of the bottom of the connecting plate 706. A hole through which the slide bar can pass is provided on the longitudinal beam plate, and the slide bar has external threads on the upper and lower parts of the longitudinal beam plate, and the upper external threads are screwed with a mounting portion, and the lower external threads are screwed with a clamping nut, and the slide bar is positioned on the longitudinal beam plate through the mounting portion and the clamping nut, and has a detachable function.

[0103] In this embodiment, a plurality of groups of oblique mounting arms 8031 ​​are installed at the bottom of the sliding support 803 by screws, and a vacuum suction cup 8032 is installed at the bottom of the oblique mounting arm 8031. The bottom of the vacuum suction cup 8032 can adsorb and fix the lining support member 30. Preferably, a metal ring 8033 is provided on the side of the oblique mounting arm 8031 ​​close to the vacuum suction cup 8032, and a clamping block 8034 is installed on the side of the metal ring 8033. The inner side of the clamping block 8034 is used to clamp and fix the lining support member 30.

[0104] In the above embodiment, when the lining support member 30 is grasped and adsorbed, the vacuum suction cup 8032 can adsorb and fix the middle part of the lining support member 30, and the clamping block 8034 can clamp and fix the edge part of the lining support member 30, which can effectively improve the safety of the lining support member 30 during transportation, and will not cause shaking or even falling off due to angle rotation and debugging operations. When installing the lining support member, the lining support member 30 can be inserted into the middle of the clamping groove of the clamping block. After the lining support member is placed, the vacuum suction cup 8031 ​​is started to suck and fix the lining support member 30. Of course, the clamping block is only used as a preferred embodiment. The present invention can also be installed without the clamping block, and only the suction cup can be used for adsorption and fixation. When there is only a suction cup, the lining support member 30 is directly sucked by the vacuum suction cup and then transported.

[0105] In the integrated platform for supporting and conveying lining materials for construction of underground caverns of hydropower stations of the present invention, when it is necessary to adjust the height of the position for conveying and erecting the lining support member 30, the lifting cylinder 804 can be started to operate, driving the sliding support 803 connected to the output end of the lifting cylinder 804 to move up and down. At this time, the multiple groups of sliding rods 801 slidably connected inside the sliding support 803 can guide the lifting and lowering of the sliding support 803 and the lining support member 30 at the bottom thereof, thereby ensuring the position accuracy when erecting the lining support member 30.

[0106] The lining support member 30 in the present invention is a material member such as a steel mesh, a steel arch frame (internal parts) or a steel grille arch frame (internal parts) for supporting and protecting the underground cavern, and may also be other support members that can achieve the same effect.

[0107] Specific reference Fig.14 and Fig.15As another embodiment of the present invention, in order to prevent the lining support member 30 from falling off during transportation and installation, a plurality of clamping blocks 8034 of the present invention are provided with inner recesses 80341, and a longitudinal conveyor belt 80342 is movably connected to a portion of the bottom of the inner recess 80341, and a rolling shaft 80343 is connected to the inner side of the longitudinal conveyor belt 80342 through a transmission wheel key, and the rolling shaft 80343 is rotatably connected to the inside of a plurality of rolling supports 80345, and the rolling supports 80345 The rolling gear 80346 is installed inside the inner concave part 80341, wherein the outer side of the rolling shaft rod 80343 is installed with a rolling gear 80346, and two groups of rolling gears 80346 are provided, and the two rolling gears 80346 are meshed and connected, and the top of the other group of rolling gears 80346 is connected with a threaded rod 80347, and the outer side of the threaded rod 80347 is threadedly connected with a pressing block 80344, and the pressing block 80344 is slidably connected with the inner concave part 80341, and the bottom of the pressing block 80344 is pressed down and fixed with a lining support member 30. The threaded rod 80347 is rotatably connected in the inner concave part 80341.

[0108] In the integrated platform for supporting and conveying lining materials for construction of underground caverns of hydropower stations of the present invention, when the clamped lining support member 30 has a tendency to fall off or even drop, it will move, thereby driving the longitudinal conveyor belt 80342 that contacts the bottom of the lining support member 30 to move. At this time, when the longitudinal conveyor belt 80342 moves, it will drive the rolling shaft rod 80343 connected to its inner side through the transmission wheel to rotate, and make a rolling gear 80346 connected to the outer side of the rolling shaft rod 80343 rotate. When a rolling gear 80346 rotates, another rolling gear 80346 meshed with its side will rotate, so that the threaded rod 80347 connected to the top of the rolling gear 80346 rotates. When the threaded rod 80347 rotates, the lower pressing block 80344 threadedly connected to its outer side will move downward, and further reinforce the lining support member 30 that has a tendency to slide and fall off.

[0109] In addition, when the above solution is adopted, two baffles 80349 connected by electric push rods 80348 are installed on the back of the sliding support 803, and the side supports of the two baffles 80349 are against the lining support member 30, wherein the side without the clamping block 8034 and the baffle can realize the grabbing, carrying and installation and laying of the lining support member 30. The two electric push rods can be fixed on the side of the metal ring, and the free ends of the two electric push rods are connected to a vertical baffle 80349. The electric push rod 80348 can control the baffle 80349 to approach or move away from the lining support member 30, such as Fig.16 shown.

[0110] When disassembling and installing the lining support member 30, the two baffles on the back of the sliding support 803 are moved by the operation of the electric push rod, so that the lining support member 30 can be disassembled from one side of the back of the sliding support 803. When this embodiment is used, since there are clamping blocks on the left and right sides of the vacuum suction cup 8032 and baffles on the back side, the lining support member 30 enters between the lower pressing block and the conveyor belt from the front of the vacuum suction cup 8032. At this time, the conveyor belt is controlled and not allowed to run until the lining support member 30 contacts the side wall of the baffle at the back side. When the installation is complete, the suction cup can be started to adsorb the lining support member. Of course, according to the working conditions, the vacuum suction cup can also be not started, and only the clamping force between the conveyor belt and the lower pressing block is used. Since the lining support member 30 is installed between the conveyor belt and the lower pressure block, and the left, right and rear sides of the lining support member are blocked, when the lining support member 30 tends to fall forward, the lining support member 30 tends to move forward with the conveyor belt 80342. The conveyor belt transmits power to the threaded rod 80347 through the engagement of two rolling gears 80346. The threaded rod 80347 rotates to drive the lower pressure block 80344 to move toward the conveyor belt 80342, so that the lining support member 30 clamped between the lower pressure block and the conveyor belt is clamped more tightly and is not easy to fall, thereby ensuring the safety of the lining support member during transportation. When the lining support member 30 needs to be removed, since the lining support member 30 moves toward the front exit, the lower pressure block 80344 will be clamped tighter. Therefore, the lining support member can only be removed from the rear at this time. A baffle controlled by an electric push rod is provided on the rear side of the vacuum suction cup 8032 (the electric push rod has two movement modes for controlling the baffle, the first is to control the baffle to move up and down, and the second is to control the baffle to move forward and backward). At this time, the electric push rod is used to move the baffle upward. After the baffle moves upward, it makes way for the lining support member and the exit. At this time, the lining support member 30 is pushed toward the rear, and the conveyor belt rotates accordingly. Since the rotation direction of the conveyor belt is opposite to that when the lower pressure block is clamped, the conveyor belt moves toward the rear at this time, causing the lower pressure block to move away from the conveyor belt, further facilitating the removal of the lining support member 30.

[0111] In this example, since the baffle located at the rear side of the vacuum suction cup is controlled by an electric push rod, the baffle controlled by the electric push rod has three implementation modes. The first is that the electric push rod moves the baffle up and down, and the second is that the electric push rod moves the baffle forward and backward.

[0112] When in use, the baffle can be removed first to make the front and back transparent, so that the operator can choose to move the lining support component from the front or behind the vacuum suction cup. In the first baffle embodiment, when moving in from the front, it is necessary to control the conveyor belt to prevent it from rotating until the lining support component hits the baffle at the rear. When it needs to be removed, just move the baffle upward to make way. In the second embodiment of the baffle, when the lining support member is moved in from the front, it is also necessary to control the conveyor belt to prevent it from rotating. After moving into place, the baffle can be moved forward to contact the lining support member. When the baffle continues to move forward, the lining support member can move forward with the conveyor belt. At this time, the lower pressure block moves downward to clamp the lining support member 30 with force, so that the lining support member is clamped more tightly. When the lining support member needs to be removed, it is only necessary to move the baffle toward the rear, and then push the lining support member to move toward the rear with the conveyor belt, so that the lower pressure block moves upward, loosens the clamping of the lining support member, and then the lining support member can be smoothly taken out.

[0113] As an embodiment of the present invention, when the lining support member 30 is adsorbed and carried, the clamping block 8034 is not installed on the outside of the oblique installation arm 8031, and only the vacuum suction cup 8032 is used to adsorb and fix the lining support member 30. At this time, when installing the above-mentioned lining support member 30, the corresponding lining support member 30 is installed to fit closely with the previous group of lining support members 30 that have been assembled and fixed (side part), which makes it more convenient for subsequent workers to weld and install the two groups of lining support members 30 that have been attached, and there is no need for the workers to support and position the lining support members 30 in other ways.

[0114] Specific reference Figure 1-Figure 15 The present invention also provides a method for using the integrated platform for supporting and conveying lining materials for construction of an underground cavern of a hydropower station, comprising the following steps:

[0115] S1. The integrated transport platform is suitable for underground cavern excavation support and concrete lining construction stages, which can greatly reduce the input of construction personnel. When transporting the lining support components 30 of support materials, steel bars, and templates, firstly, the lifting and grabbing assembly 80 is used to complete the grabbing and fixing of the lining support components 30. At this time, the design of the internal parts of the lifting and grabbing assembly 80 makes the lining support components 30 more firm and stable when being grabbed and fixed, effectively reducing the risk of the lining support components 30 falling off or even falling during the transportation process;

[0116] S2. During the actual transportation of the lining support member 30, the oil cylinder flip assembly 50, the steering assembly 60 and the vertical rotation assembly 70 drive the grasped lining support member 30 to rotate and move at multiple angles, so as to meet the different installation and laying requirements of the grasped fixed lining support member 30;

[0117] S3. During the construction of lining concrete reinforcement, the lifting and grabbing assembly 80 absorbs and fixes the lining support member 30, which effectively reduces the amount of scaffolding erection and safety risks.

[0118] Without limitation, any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent substitutions or changes according to the technical solution and inventive concept of the present invention, should be covered by the protection scope of the present invention.
