[0002] In construction, tower cranes are basically used to lift and transport materials. However, traditional tower cranes are large in size and are suitable for use in high-rise buildings, but not for low-rise buildings. On the one hand, the tower crane has insufficient operating space, and on the other hand, the cost of use is high. Therefore, conveyors are basically used to transport building materials in low-rise building construction. Conveyors can be divided into the following types according to their operation mode: integrated conveyors, belt conveyors, screw conveyors, lifting conveyors, roller conveyors, plate chain conveyors, mesh belt conveyors and chain conveyors. A lifting conveyor is generally used for conveying materials upward. The lifting conveyor mainly lifts and conveys materials through an electric hoist. Specifically, building materials are piled in a box, and the hook of the electric hoist is hung on the lifting ring of the box. The box is lifted by winding up the traction rope and lowered by lowering the traction rope. However, the coordination position of the hook and the lifting ring has freedom of movement, and the traction rope itself has freedom of movement, which causes the box to sway easily during the lifting process.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0017] Embodiment 1 like Figures 1 to 11As shown, a material conveying device for construction includes a lifting conveyor, which includes a tower body 1, a rotating conveying arm 2, a limiting plate 3 and a storage box 6. The rotating conveying arm 2 is rotatably installed on the top of the tower body 1, and the tower body 1 is perpendicular to the rotating conveying arm 2. A horizontal slide 4 is arranged on the rotating conveying arm 2, and the horizontal slide 4 has the freedom to move along the length direction of the rotating conveying arm 2. An electric hoist 5 is installed on the horizontal slide 4, and a limiting column 7 is connected to the traction rope of the electric hoist 5. The limiting plate 3 is movably mounted on the tower body 1, and the limiting plate 3 moves with the electric hoist 5. A limiting hole 8 is penetrated through the limiting plate 3, and the limiting column 7 is penetrated in the limiting hole 8. 7 is inserted into the top of the storage box 6, and a box door is hinged on one side of the storage box 6. The box door and the storage box 6 are connected by a latch. The box door is opened, and the building materials (ceramic tiles, bricks, etc.) are stacked in the storage box 6. Then the box door is locked, and the electric hoist 5 lowers the traction rope to move the limit column 7 downward. During the movement of the limit column 7 downward, the limit plate 3 moves downward synchronously with the limit column 7, so that the limit column 7 is always inserted into the limit hole 8. Then, the limit column 7 is connected to the storage box 6, abandoning the traditional connection method of the hook and the ring, so that there is no freedom of movement between the storage box 6 and the limit column 7, and the electric hoist 5 reels the traction rope to lift the storage box 6. During the lifting process In the embodiment, the limiting plate 3 moves synchronously with the limiting column 7, so that the limiting column 7 is always restricted in the limiting hole 8, thereby limiting the horizontal movement freedom of the limiting column 7, and the limiting column 7 limits its vertical movement freedom under the gravity of the storage box 6, so that the transportation of the storage box 6 is more stable, and there will be no shaking or swinging, thereby improving the transportation safety and protecting the materials from damage. After being lifted to the specified height, the storage box 6 is placed in the specified position in conjunction with the rotation movement of the rotating conveying arm 2 and the horizontal movement of the horizontal slide 4, and then in conjunction with the lowering action of the electric hoist 5. After the swing of the storage box 6 is eliminated, the storage box 6 can be lifted and placed in the specified position, and the workers can also When the workers are guiding the storage box 6 to be lowered, the storage box 6 will not swing and collide with the workers, thereby improving the safety of construction. After the storage box 6 is lowered to the designated position, the workers remove the storage box 6 and install the previous empty storage box 6 on the limiting column 7. The conveying device conveys the empty storage box 6 to the ground for loading of materials, and this process is repeated to achieve the lifting and transportation of building materials. Through the above-mentioned arrangement, the limiting plate 3 does not bear the weight of the storage box 6, and the storage box 6 is directly lifted by the electric hoist 5. The limiting plate 3 only limits the limiting column 7, so that the limiting plate 3 does not need too high an installation strength, thereby reducing the installation requirements of the limiting plate 3.

[0018] Furthermore, if Figure 1 , Fig.10 and Fig.11As shown, a rotating main shaft 43 is rotatably installed on the top of the tower body 1, and the rotating conveying arm 2 is fixedly connected to the rotating main shaft 43. A stepper motor 44 is installed on the tower body 1, and a small gear 45 is connected to the output shaft of the stepper motor 44. A large gear 46 is set on the rotating main shaft 43, and the large gear 46 meshes with the small gear 45. The stepper motor 44 drives the rotating main shaft 43 to rotate through the meshing of the small gear 45 and the large gear 46, and the rotating main shaft 43 drives the rotating conveying arm 2 to rotate, and the lowering position of the storage box 6 is adjusted in coordination with the movement of the horizontal slide 4; the rotating conveying arm 2 includes a rotating arm 47 and an I-beam 4 8. The rotating arm 47 is connected to the rotating main shaft 43. Two I-beams 48 are horizontally fixed at one end of the rotating arm 47. The two I-beams 48 are arranged at intervals in the horizontal direction. The horizontal slide 4 is located between the two I-beams 48. Both sides of the horizontal slide 4 are rotatably connected with running wheels 49. The running wheels 49 are located in the C-shaped notch of the I-beam 48. The running wheels 49 are driven by the shaft and the driving motor. This belongs to the prior art and will not be repeated. The running wheels 49 roll in the C-shaped notch of the I-beam 48, which has a limiting effect on the horizontal slide 4 to prevent the horizontal slide 4 from falling from the rotating conveying arm 2.

[0019] Embodiment 2 Based on the first embodiment, Figures 1 to 4As shown, the limiting plate 3 includes a lifting plate 9, a rotating plate 10 and a moving plate 11. A rectangular groove 12 is opened through the middle of the lifting plate 9. The tower body 1 is in the shape of a hollow cuboid. The tower body 1 is slidably adapted to the rectangular groove 12. A hollow shaft 13 is rotatably arranged on the lifting plate 9. The rotating plate 10 is fixedly sleeved on the hollow shaft 13. A rubber ring is arranged between the rotating plate 10 and the hollow shaft 13. The rubber ring is in a compressed state. The axis of the hollow shaft 13 is coaxial with the rotation axis of the rotating conveying arm 2. The moving plate 11 is slidably penetrated at one end of the rotating plate 10 away from the lifting plate 9. The limiting hole 8 is opened on the moving plate 11. The two opposite outer walls of the tower body 1 are opened There is a lifting groove 14, and a lifting mechanism is arranged in the lifting groove 14. The lifting mechanism and the electric hoist 5 operate synchronously. The lifting mechanism includes a rotatably installed driving shaft 15 and a driven shaft 16. The driving shaft 15 and the driven shaft 16 are arranged at intervals along the height direction of the tower body 1. The driving shaft 15 and the driven shaft 16 are respectively provided with a driving sprocket 17 and a driven sprocket 18. The driving sprocket 17 is connected to the driven sprocket 18 through a chain 19. The lifting plate 9 is connected to the chain 19. A motor 20 is installed on the tower body 1. The output shaft of the motor 20 is connected to the driving shaft 15. The rotating plate 10 is sequentially provided with a small diameter groove 21 and a large diameter groove 22 in the direction close to the lifting plate 9. The sliding groove 22 is provided in the large diameter groove 22. The movable plate 11 is slidably adapted to the small-diameter groove 21, and the baffle 23 cannot pass through the small-diameter groove 21 to prevent the movable plate 11 from being separated from the rotating plate 10. The motor 20 drives the driving shaft 15 to rotate, and the driving shaft 15 drives the driven shaft 16 to rotate through the chain 19, so that the chain 19 rotates in a cycle, and the lifting plate 9 is driven by the chain 19 to move up and down. The lifting plate 9 makes the entire limit plate 3 move up and down, and the motor 20 runs synchronously with the electric hoist 5, and the moving speed of the lifting plate 9 is equal to the moving speed of the limit column 7, thereby ensuring that the limit column 7 is always inserted in the limit hole 8, and the rotating plate 10 can rotate on the lifting plate 9 to be synchronized with the rotating plate 10. The rotation of the conveying arm 2, through the setting of the hollow shaft 13, can make the rotation axis of the limit plate 3 coaxial with the rotation axis of the rotating conveying arm 2 without interfering with the movement of the lifting plate 9, so that the limit column 7 is always inserted into the limit hole 8, and at the same time does not affect the adjustment of the lowering position of the storage box 6. When the rotating conveying arm 2 rotates, the limit column 7 rotates, and the limit column 7 pulls the limit plate 3 to follow the rotation. Through the setting of the rubber ring, there is a large friction between the hollow shaft 13 and the rotating plate 10, and the rotational freedom of the rotating plate 10 is locked by this friction. When the rotating conveying arm 2 does not rotate, the limit plate 3 does not rotate with it, so that the lifting of the storage box 6 is more stable.By sliding the moving plate 11 on the rotating plate 10, the moving plate 11 is made to move synchronously with the horizontal slide 4. Similarly, an elastic layer is mounted on the moving plate 11, and the elastic layer is interference-fitted with the small-diameter groove 21, so that there is a large friction force between the moving plate 11 and the rotating plate 10, so that when the horizontal slide 4 stops, this friction force can lock the position of the moving plate 11 to prevent the storage box 6 from swinging. In summary, the lifting plate also has three degrees of freedom, and these three degrees of freedom correspond to the three degrees of freedom of the limit column 7. The limit plate 3 is synchronously moved with the limit column 7 by synchronous operation or driving operation, so that the limit column 7 is always inserted in the limit hole 8, thereby limiting the storage box 6, so that the storage box 6 will not swing during the lifting process. ;

[0020] Based on the second embodiment, when the use environment of the material conveying device is a windy environment, or when the swing requirement is high, the rotating plate 10 and the moving plate both adopt a synchronous operation mode to follow the movement of the limit column 7, and a first motor is installed on the lifting plate 9, and the output shaft of the first motor is connected to the first gear. The second gear is mounted on the hollow shaft 13, and the second gear meshes with the first gear. The first motor is synchronized with the motor 20, so that the rotating conveying arm 2 and the limit plate 3 rotate synchronously. When the rotating conveying arm 2 stops rotating, the rotation of the limit plate 3 is limited by the self-locking of the first motor. Similarly, a rack is fixed on the top of the moving plate 11, and a second motor is installed on the rotating plate 10. The output shaft of the second motor is connected to the third gear. A driving window is opened on the top surface of the rotating plate 10 along the moving direction of the moving plate 11. The third gear passes through the driving window and meshes with the rack. The second motor is synchronized with the movement of the horizontal slide 4. When the horizontal slide 4 stops moving, the movement of the moving plate 11 is limited by the self-locking of the second motor, thereby strengthening the limiting strength of the limit column 7, and can adapt to harsh environments or high requirements.

[0021] Embodiment 3 In order to increase the material conveying speed, the number of storage boxes 6 is not less than three. One storage box 6 is unloaded by workers at a designated position, and the other is located on the ground and loaded by workers. The material conveying device conveys the third empty storage box 6 to the ground, and then conveys the fully loaded storage box 6 to the designated position. The storage box 6 that has been unloaded last time is again conveyed to the ground by the material conveying device for loading. In this way, the loading, unloading and material conveying actions overlap, which greatly improves the conveying efficiency. Under this conveying mode, the limit column 7 and the storage box 6 need to be frequently connected and disassembled. Therefore, the traditional method of using hooks and rings is mainly to achieve quick installation and disassembly. For this reason, in order not to affect the quick installation and disassembly of the storage box 6, on the basis of Example 2, as Figures 5 to 9As shown, the side wall of the limiting column 7 is symmetrically provided with a plurality of snap-fit ​​components, the plurality of snap-fit ​​components are evenly distributed along the height direction of the limiting column 7, and the plurality of snap-fit ​​components are staggered in the horizontal direction, the snap-fit ​​components include two first 7-shaped hooks 24, the two first 7-shaped hooks 24 are symmetrically fixed in the horizontal direction, a mounting circular hole 33 is provided on the top of the storage box 6, each first 7-shaped hook 24 is correspondingly provided with a second 7-shaped hook 25, the second 7-shaped hook 25 is slidably penetrated on the side wall of the mounting circular hole 33, the opening of the first 7-shaped hook 24 faces upward, and the opening of the second 7-shaped hook 25 faces downward, the first 7-shaped hook 24 and the second 7-shaped hook 25 are hook-shapedly buckled, the limiting column 7 is inserted into the mounting circular hole 33 on the top of the storage box 6, the outer wall of the limiting column 7 contacts the inner wall of the mounting circular hole 33, which can greatly reduce the limiting column 7 in the installation. The radial movement amount in the mounting circular hole 33, during the process of inserting the limiting post 7 into the mounting circular hole 33, the second 7-shaped hook 25 moves into the storage box body 6, so that the second 7-shaped hook 25 is separated from the mounting circular hole 33, so that the first 7-shaped hook 24 can smoothly pass through the second 7-shaped hook 25. When the limiting post 7 is inserted into the position, the hook-shaped portion of the second 7-shaped hook 25 moves into the mounting circular hole 33 and is located above the first 7-shaped hook 24. At this time, the limiting post 7 is lifted, and the limiting post 7 drives the first 7-shaped hook 24 to engage the second 7-shaped hook 25, thereby connecting the limiting post 7 to the storage box body 6. It only needs to be inserted into the specified position, and then the limiting post 7 is lifted to complete the quick connection between the limiting post 7 and the storage box body 6. The operation is simple and reliable, and at the same time, the freedom of movement of the limiting post 7 can be limited to avoid the situation of lifting and swinging. Since the materials used in construction are heavy, in order to make the connection strength between the limit column 7 and the storage box 6 meet the lifting of large-mass materials, the clamping components are divided into two groups. The two groups of clamping components are symmetrically arranged on the limit column 7 to make the force uniform. Each group of clamping components is provided with multiple, so that the connection between the limit column 7 and the storage box 6 has multiple symmetrical force positions, which greatly improves the connection strength between the limit column 7 and the storage box 6. Secondly, in order to ensure the stability of the connection between the limit column 7 and the storage box 6, each clamping component includes two A 7-shaped hook 24 makes the connection stable, stronger and more uniform. Since the first 7-shaped hook 24 needs to be matched with a second 7-shaped hook 25, in order to avoid the mutual influence of the clamping components, the first 7-shaped hooks 24 in each clamping component are staggered in the horizontal direction, so that each longitudinal position of the limit column 7 has only one group of first 7-shaped hooks 24 and second 7-shaped hooks 25, which can avoid mutual influence and make the first 7-shaped hook 24 stably buckle with the corresponding second 7-shaped hook 25. Preferably, two are set for each group of clamping components to ensure the connection strength and simplify the structure of the limit column 7.

[0022] Furthermore, if Figures 5 to 9As shown, the limiting column 7 is provided with a slot 26 at the position where the first 7-shaped hook 24 is provided, and the first 7-shaped hook 24 is fixedly installed in the slot 26. The storage box 6 is provided with a horizontal slot 27 and a vertical slot 28 at the position where the second 7-shaped hook 25 is provided, and the vertical slot 28 is located between the limiting column 7 and the horizontal slot 27. One end of the horizontal slot 27 is connected to the vertical slot 28, and the other end is connected to the installation cavity 29. The horizontal portion of the second 7-shaped hook 25 is slidably adapted to the horizontal slot 27, and the vertical slot The second 7-shaped hook 25 is provided with a wedge-shaped surface 32 on the top of the second 7-shaped hook 25. The wedge-shaped surface 32 is located on the moving path of the limiting column 7. When the spring 31 is in a normal state, the second 7-shaped hook 25 is provided with a wedge-shaped surface 32 on the top of the second 7-shaped hook 25. The second 7-shaped hook 25 is provided with a wedge-shaped surface 32 on the moving path of the limiting column 7. When the spring 31 is in a normal state, the second 7-shaped hook 25 is provided with a wedge-shaped surface 32 on the top of the second 7-shaped hook 25. The hook 25 extends into the slot 26 to cooperate with the first 7-shaped hook 24. Through the setting of the slot 26, the first 7-shaped hook 24 can be received and installed in the slot 26, so that the outer wall of the limiting column 7 can contact the inner wall of the mounting hole 33 to reduce the radial movement. In the process of inserting the limiting column 7, the limiting column 7 sequentially squeezes the wedge surfaces 32 of the plurality of second 7-shaped hooks 25. Under the guidance of the wedge surfaces 32, the second 7-shaped hook 25 squeezes the spring 31 to move into the horizontal groove 27, so that the first 7-shaped hook 24 can be received and installed in the slot 26, so that the outer wall of the limiting column 7 can contact the inner wall of the mounting hole 33 to reduce the radial movement. In the process of inserting the limiting column 7, the limiting column 7 squeezes the wedge surfaces 32 of the plurality of second 7-shaped hooks 25 in sequence. Under the guidance of the wedge surfaces 32, the second 7-shaped hook 25 squeezes the spring 31 to move into the horizontal groove 27, so that the first 7-shaped hook 24 can be inserted into the slot 26. The vertical portion of the second 7-shaped hook 25 is located in the vertical groove 28, so that the limiting column 7 can be smoothly moved to the specified position through the second 7-shaped hook 25. After the limiting column 7 is inserted into place, the notch 26 corresponds to the corresponding second 7-shaped hook 25. The second 7-shaped hook 25 is inserted into the notch 26 under the reaction force of the spring 31. Finally, the limiting column 7 is lifted up, so that the first 7-shaped hook 24 and the second 7-shaped hook 25 can be buckled, completing the quick connection between the limiting column 7 and the storage box 6.

[0023] Embodiment 4 The third embodiment realizes the quick connection between the limiting column 7 and the storage box 6, but when disassembling, the limiting column 7 cannot be directly pulled out. Therefore, in order to realize the quick disassembly of the limiting column 7 and the storage box 6, on the basis of the third embodiment, Figures 5 to 9As shown, a push plate 34 is slidably arranged in the installation circular hole 33, and the push plate 34 is located below the second 7-shaped hook 25. A strip groove 35 is provided on the side wall of the installation circular hole 33, and each installation cavity 29 is correspondingly provided with a strip groove 35, and the strip groove 35 is communicated with the corresponding installation cavity 29. A pull wire 36 is connected to the limit baffle 30, and the pull wire 36 passes through the strip groove 35 and is connected to the side wall of the push plate 34. A plurality of guide wheels 37 are rotatably arranged at the rear of the limit baffle 30, and the pull wire 36 is wound into a C shape through the plurality of guide wheels 37. A spring groove 38 is provided at the bottom of the installation circular hole 33, and a reset spring 39 is connected in the spring groove 38. The reset spring 39 is connected to the push plate 34. When the push plate 34 contacts the bottom of the installation circular hole 33, the second 7-shaped hook 25 The vertical portion of the hook 25 is located in the vertical groove 28, and a guide block 40 is fixed to the side wall of the limiting column 7. Two guide grooves 41 are symmetrically opened on the inner wall of the mounting hole 33, and the guide grooves 41 extend to the top of the storage box 6. An arc groove 42 is opened on the inner wall of the mounting hole 33, and the two ends of the arc groove 42 are respectively connected to the two guide grooves 41. When the guide block 40 is slidably adapted in one of the guide grooves 41, the second 7-shaped hook 25 is located on the moving path of the first 7-shaped hook 24. When the guide block 40 is slidably adapted in the other guide groove 41, the first 7-shaped hook 24 and the second 7-shaped hook 25 are in a staggered state. The two guide grooves 41 are distinguished by markings. One guide groove 41 is used for connecting the limiting column 7 with the storage box 6, and the other guide groove 4 1 is used for disassembling the limiting column 7 and the storage box 6. When connected, the guide block 40 slides into the corresponding guide groove 41 for connection. Through the cooperation of the guide groove 41 and the guide block 40, the limiting column 7 can be accurately inserted into the installation circular hole 33, so that the second 7-shaped hook 25 is located on the moving path of the first 7-shaped hook 24. When the limiting column 7 contacts the pushing plate 34, under the influence of the reset spring 39, the limiting column 7 will feel obvious resistance when it is inserted further. At this time, it indicates that the limiting column 7 has been inserted into place, and the limiting column 7 can be released to start the material conveying device to lift the storage box 6. During the lifting process, the limiting column 7 moves up a certain distance, so that the first 7-shaped hook 24 and the second 7-shaped hook 25 are buckled, and the connection between the limiting column 7 and the storage box 6 is completed. When it is needed When the limiting column 7 is to be removed, the limiting column 7 is continued to be moved downward, and the limiting column 7 will press the push plate 34 to move, and at the same time, the first 7-shaped hook 24 is separated from the second 7-shaped hook 25, and the push plate 34 compresses the reset spring 39 and moves downward. During the downward movement of the push plate 34, the pull wire 36 is pulled, and the direction of the force is changed through a plurality of guide wheels 37, so that during the downward movement of the push plate 34, the second 7-shaped hook 25 is driven to move into the installation cavity 29 through the pull wire 36. At this time, the second 7-shaped hook 25 squeezes the spring 31 to move the vertical portion into the vertical groove 28. At this time, the guide block 40 moves into the arc groove 42, and the push plate 34 contacts the bottom of the installation hole 33, indicating that the limiting column 7 has moved to the disassembly position, and then the limiting column 7 is rotated.When the limit column 7 cannot be rotated, the guide block 40 corresponds to another guide groove 41. At this time, the limit column 7 is lifted up to make the guide block 40 fit into another guide groove 41 to guide the removal of the limit column 7. Since the limit column 7 rotates 180°, and the two sets of snap-fit ​​components are arranged symmetrically at 180°, after the limit column 7 rotates 180°, the area of ​​the limit column 7 where the snap-fit ​​components are not set corresponds to the second 7-shaped hook 25, and the complete side wall of the limit column 7 blocks the second 7-shaped hook 25 from moving into the installation circular hole 33. At this time, the limit column 7 can be directly pulled out upward. Therefore, the removal of the limit column 7 and the storage box 6 only requires moving downward and then rotating and lifting. The removal operation is also simple and reliable.
