Description

Technical Field

[0001] The invention relates to the technical field of cranes, and in particular to a steel bar transport hoist with a protective function. Background Art

[0002] In modern construction projects, steel bars are an important part of building structures. The safety and efficiency of their transportation and hoisting are crucial to the progress of the project. With the development of the construction industry, the demand for the handling of heavy materials such as steel bars continues to increase, and cranes have become an indispensable equipment on construction sites. The traditional way of hoisting steel bars is usually for workers to manually bundle and stack the steel bars, then use two ropes to fix them on both sides of the steel bar pile, and finally connect the ropes to the crane hook for hoisting.

[0003] During this process, workers rely on their eyes and intuition to fix the ropes on the left and right sides of the steel pile. However, this method makes it difficult to ensure that the distance between the two ropes and the middle of the steel pile is exactly the same, which may cause the steel bars to tilt or be unbalanced during hoisting. When the steel bars tilt in the air, some of them may slide down due to gravity, increasing construction risks and endangering the safety of on-site personnel. In addition, since the force distribution of the two ropes is uneven, that is, one rope bears more tension, this will increase the risk of the rope breaking. Once it breaks, all the steel bars will lose support and are likely to fall, causing serious safety accidents. In this case, not only the lives of on-site workers are threatened, but the accident may also cause project delays and increase project costs. Summary of the invention

[0004] In view of this, the present invention provides a steel bar transport hoist with a protective function, which can overcome the disadvantage that when the existing crane is lifting the steel bars, the steel bars are easily tilted in the air, which may cause the steel bars to slip or fall, which not only poses a threat to the life safety of on-site workers, but also may cause project delays due to accidents and increase project costs.

[0005] The technical implementation scheme of the present invention is: a steel bar transport hoist with protective function, comprising: a guide rail; a sliding seat, slidably connected to the guide rail; a controller, installed on the side of the sliding seat; a fixed block, symmetrically connected to both sides of the sliding seat; a mounting block, connected to the top of the fixed block; a hinge block, rotatably connected to the mounting block; a contact switch, installed on the side of the hinge block, and the contact switch contacts and cooperates with the side of the fixed block; a fixed seat, connected to the top of the sliding seat; a rotating seat, rotatably connected to the fixed seat; a fixing rod, connected to the rotating seat; a moving component, arranged on the sliding seat, used to drive the sliding seat to move on the guide rail; a fixing component, arranged on the guide rail, used to fix the steel bar bundle.

[0006] More preferably, the moving assembly includes: a fixed rack symmetrically connected to both sides of the guide rail; a driving motor symmetrically installed on the fixed block; a rotating gear connected to the output shaft of the driving motor, and the rotating gear is meshed with the fixed rack.

[0007] More preferably, the fixing assembly includes: a mounting frame, symmetrically connected to the bottom of the guide rail; a first winch, mounted inside the mounting frame, and a steel wire rope of the first winch slides through the bottom of the mounting frame; a safety buckle, mounted on the end of the steel wire rope of the first winch; a connecting ring, connected to the side of the mounting frame, and the safety buckle can be buckled on the connecting ring.

[0008] More preferably, it further comprises: a connecting rod connected to the steel wire rope of the first winch.

[0009] More preferably, it further comprises: a limiting plate connected to the bottom of the installation frame.

[0010] More preferably, it further comprises: a driven gear ring connected to the rotating seat; a servo motor installed on the side of the sliding seat; a driving gear connected to the output shaft of the servo motor, and the driving gear is meshed with the driven gear ring.

[0011] More preferably, it also includes: a connecting block, symmetrically connected to both sides of the installation frame; a second winch, installed on the side of the connecting block on one side, and the wire rope end of the second winch is connected to the side of the connecting block on the other side; a sleeve frame, arranged at the end of the steel bar bundle; an arc tube, connected to the side of the sleeve frame, and the wire rope of the second winch slides through the inside of the arc tube.

[0012] More preferably, it also includes: a connecting seat connected to the bottom of the guide rail; a supporting rod symmetrically rotatably connected to both sides of the connecting seat; a latch symmetrically slidably connected to both sides of the connecting seat, and the latch is used to limit the supporting rod.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The present invention can detect and automatically adjust the balance of the steel bar bundle during the lifting process in real time by arranging components such as a sliding seat, a contact switch and a driving motor on the guide rail. When the steel bar bundle is tilted, the sliding seat will automatically move according to the signal of the contact switch to ensure that the steel bar bundle always remains in a horizontal state. This design can effectively avoid the phenomenon of some steel bars sliding off due to the tilt of the steel bar bundle, improve the safety of lifting, reduce the risks of the construction site, and protect the lives of on-site personnel.

[0014] 2. The present invention ensures that the steel bar bundle will not loosen or slip during the lifting process by designing multiple fixing methods, including the steel wire rope, limit plate, sleeve frame and supporting rod of the first winch. In particular, the design of the second winch and the sleeve frame can further limit the movement of the two ends of the steel bar bundle to prevent the internal steel bars from loosening during the lifting process. In addition, the supporting rod forms a U-shaped frame after the steel bar bundle is lifted to support the middle part of the steel bar bundle to prevent it from bending and deformation. These multiple fixing measures can enhance the stability of the lifting and ensure the safety of the steel bar bundle during the entire transportation process.

[0015] 3. The present invention designs components such as a servo motor, a driven gear ring and a driving gear, and can automatically adjust the orientation of the steel bar bundle through a controller after the steel bar bundle is hoisted to a specified position. The automatic adjustment function of the present invention can not only save time and labor, but also completely eliminate the safety hazards caused by manual operation of workers, thereby improving work efficiency and safety.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Embodiment: A steel bar transport hoist with protective function, such as Figure 1-Figure 5As shown, it includes a guide rail 1, a sliding seat 2, a controller 3, a fixed block 4, a mounting block 5, a hinge block 6, a contact switch 7, a fixed seat 8, a rotating seat 9, a fixed rod 10, a moving component and a fixed component. The guide rail 1 is slidably connected to the sliding seat 2, and the controller 3 is installed on the upper left front side of the sliding seat 2. The left and right sides of the sliding seat 2 are connected to the fixed blocks 4, and the tops of the two fixed blocks 4 are connected to the sides away from each other. The mounting blocks 5 are in an inverted L shape, and the lower parts of the two mounting blocks 5 are rotatably connected to the hinge blocks 6. The two hinge blocks 6 are respectively located at the two fixed blocks 4 away from the sliding On one side of the moving seat 2, since the hinge block 6 can rotate freely on the mounting block 5, the hinge block 6 can always maintain a vertical state under the action of gravity. A contact switch 7 is installed on the side where the two hinge blocks 6 are close to each other, and the contact switch 7 is in contact with the side of the corresponding fixed block 4. A fixed seat 8 is connected to the top of the sliding seat 2, and a rotating seat 9 is rotatably connected to the fixed seat 8. A fixed rod 10 is connected to the upper part of the rotating seat 9, and the fixed rod 10 is used to be hung on the hook of the crane. The moving assembly is used to drive the sliding seat 2 to move on the guide rail 1; the fixed assembly is used to fix the steel bar bundle 001.

[0031] like Figure 4 As shown, the moving assembly includes a fixed rack 11, a driving motor 12 and a rotating gear 13. The front and rear sides of the guide rail 1 are connected to the fixed rack 11, and the front and rear sides of the two fixed blocks 4 are connected to the driving motors 12. The number of the driving motors 12 is four, and the output shafts of the four driving motors 12 are connected to the rotating gears 13. The rotating gears 13 on the front and rear sides are respectively engaged with the fixed racks 11 on the front and rear sides, so that the driving motor 12 drives the rotating gear 13 to rotate, and the rotating gear 13 can move left and right along the fixed rack 11, thereby driving the sliding seat 2 to move left and right on the guide rail 1.

[0032] like Figure 4 and Figure 5 As shown, the fixing assembly includes a mounting frame 14, a first hoist 15, a safety buckle 16, a connecting ring 17, a connecting rod 18 and a limit plate 19. The left and right sides of the bottom of the guide rail 1 are connected to the mounting frame 14. The first hoists 15 are installed inside the two mounting frames 14, and the steel wire rope of the first hoist 15 slides through the bottom of the mounting frame 14. The safety buckle 16 is also installed at the end of the steel wire rope of the first hoist 15. The lower rear parts of the two mounting frames 14 are connected to the connecting ring 17, and the safety buckle 16 can be buckled on the connecting ring 17. The steel wire ropes of the two first hoists 15 are connected with a connecting rod 18. The bottom of the two mounting frames 14 are connected to the limit plate 19, and the shape of the limit plate 19 is an inverted U shape, so that the limit plate 19 can limit the front and rear sides of the steel bar bundle 001 to prevent the steel bar bundle 001 from swinging in the air.

[0033] Initially, the sliding seat 2 is located in the middle position of the guide rail 1, and the two contact switches 7 are in contact with the sides of the two fixed blocks 4 respectively; first, the guide rail 1 is placed in the middle position of the top of the steel bar bundle 001, ensuring that the limit plate 19 can surround the front and rear sides of the steel bar bundle 001, and then the connecting rod 18 passes through the bottom of the steel bar bundle 001 from the front side and is pushed to the back side, so that the steel wire rope of the first winch 15 completely surrounds the steel bar bundle 001, and then the safety buckle 16 is buckled on the connecting ring 17 to ensure that the steel wire rope firmly fixes the steel bar bundle 001, and then the controller 3 is used to control the first winch 15 to reel in the steel wire rope thereon, so that the steel bar bundle 001 can be tightly fixed to the bottom of the installation frame 14; then the crane hook can be hooked to the fixing rod 10, and then control the crane hook to lift the fixed rod 10 upward for a distance, so that the rotating seat 9, the fixed seat 8, the guide rail 1 and the installation frame 14 can move upward for a distance, and the installation frame 14 can lift the steel bar bundle 001 and separate it from the ground through the steel wire rope of the first hoist 15; if the distances between the two installation frames 14 and the middle position of the steel bar bundle 001 are inconsistent at this time, the steel bar bundle 001 will tilt (for example: if the distance between the installation frame 14 on the left and the middle position of the steel bar bundle 001 is shorter, the sliding seat 2 is located on the right side of the center of gravity of the steel bar bundle 001. At this time, the steel wire rope of the first hoist 15 on the left side is subject to a greater gravity of the steel bar bundle 001, and the guide rail 1 will be inclined with the left lower and the right higher, resulting in the steel bar bundle 001 tilting. The bundle 001 will also be in an inclined state with the left side lower and the right side higher). At this time, the fixed block 4 will tilt synchronously with the guide rail 1, and the contact switch 7 on the left will disengage from the side of the fixed block 4 on the left. The contact switch 7 on the left will send a signal. After receiving the signal, the controller 3 will control the drive motor 12 to drive the rotating gear 13 to rotate forward, so that the rotating gear 13 rolls to the left on the fixed rack 11, thereby driving the sliding seat 2 to move to the left on the guide rail 1. At this time, the guide rail 1 will gradually rotate to a horizontal state, driving the steel bundle 001 to gradually rotate to a horizontal state. When the guide rail 1 returns to a horizontal state, that is, the sliding seat 2 is located directly above the center of gravity of the steel bundle 001, the contact switch 7 on the left will contact the side of the fixed block 4 on the left again. At this time, the contact switch 7 on the left will send a signal. After receiving the signal, the controller 3 will control the drive motor 12 to stop working, and then the steel bundle 001 can be hoisted and transported by the crane. Similarly, if the steel bundle 001 is in a tilted state with the left side higher than the right side, the controller 3 will control the drive motor 12 to drive the rotating gear 13 to reverse, thereby controlling the sliding seat 2 to move to the right on the guide rail 1 until the steel bundle 001 maintains a horizontal state; during the hoisting of the steel bundle 001, the limit plate 19 can limit the steel bundle 001 forward and backward, thereby limiting the wire rope of the first winch 15, preventing the wire rope of the first winch 15 from swinging forward and backward, and ensuring the stability of the steel bundle 001 during the hoisting process.

[0034] like Figure 6As shown, it also includes a driven ring gear 20, a servo motor 21 and a driving gear 22. The driven ring gear 20 is connected to the lower outer side of the rotating seat 9, and the servo motor 21 is installed on the rear side of the sliding seat 2. The output shaft of the servo motor 21 is connected to the driving gear 22, and the driving gear 22 is meshed with the driven ring gear 20; when the steel bar bundle 001 is hoisted to the specified position, if the orientation of the steel bar bundle 001 is incorrect, the servo motor 21 can be controlled by the controller 3 to drive the driving gear 22 to rotate slowly, so that the driving gear 22 can roll around the outer side of the driven ring gear 20, thereby driving the sliding seat 2 to rotate horizontally under the hook of the crane, and then driving the steel bar bundle 001 to rotate horizontally to adjust the orientation, until the steel bar bundle 001 is adjusted to the specified orientation, the servo motor 21 can be controlled by the controller 3 to stop working, so that there is no need for workers to use ropes to pull the steel bar bundle 001 to rotate and adjust the orientation, which not only saves time and effort, but also prevents workers from being accidentally injured, thereby improving safety.

[0035] like Figure 7 and Figure 8 As shown, it also includes a connecting block 23, a second hoist 24, a sleeve frame 25 and an arc tube 26. The front and rear sides of the two installation frames 14 are connected to the connecting blocks 23, the front sides of the two connecting blocks 23 on the front side are both installed with the second hoist 24, and the wire rope end of the second hoist 24 is fixedly connected to the right side of the connecting block 23 on the rear side. The left and right ends of the steel bar bundle 001 are provided with sleeve frames 25, and the middle parts of the two sleeve frames 25 away from each other are connected with the arc tube 26, and the wire rope of the second hoist 24 slides through the inside of the arc tube 26; when the guide rail 1 is placed in the middle of the top of the steel bar bundle 001, the second hoist can be controlled by the controller 3. The winch 24 loosens the steel wire rope on it. At this time, the worker can pull the two sleeves 25 to the side away from each other and place them on the left and right ends of the steel bar bundle 001 respectively. Then, the controller 3 controls the second winch 24 to reel in the steel wire rope on it. The steel wire rope of the second winch 24 can pull the arc tube 26 and the sleeve 25 on the left and right sides to move towards each other, so that the sleeves 25 on the left and right sides are respectively sleeved on the left and right ends of the steel bar bundle 001, thereby further limiting and fixing the steel bar bundle 001 to prevent some steel bars inside the steel bar bundle 001 from loosening and sliding during the lifting process, thereby ensuring the safety of on-site workers.

[0036] like Fig. 9As shown, it also includes a connecting seat 27, a supporting rod 28 and a latch 29. The connecting seat 27 is connected to the middle of the bottom of the guide rail 1. The front and rear sides of the connecting seat 27 are rotatably connected to the supporting rods 28. The supporting rods 28 are in an L-shape. The front and rear sides of the connecting seat 27 are also slidably connected to the latch 29. The latch 29 is located on the outside of the supporting rod 28 and is used to limit the supporting rod 28. Initially, the two supporting rods 28 are in an open state. When the guide rail 1 is placed in the middle of the top of the steel bar bundle 001, the two supporting rods 28 are respectively located on the front and rear sides of the steel bar bundle 001. When the steel bar bundle 001 is lifted for a while When the distance between the two support rods 28 and the ground is separated, the worker can rotate the two supporting rods 28 to the side closer to each other so that the lower ends of the two supporting rods 28 touch each other, and then insert the two pins 29 into the front and rear sides of the connecting seat 27 respectively to limit the supporting rods 28. At this time, the two supporting rods 28 can form a U-shaped frame, so as to support the part of the steel bar bundle 001 located between the two installation frames 14 to prevent the steel bar bundle 001 from bending and deformation, and also make the guide rail 1 more evenly stressed, so that the steel bar bundle 001 can remain in a horizontal state during the lifting process to prevent the steel bar bundle 001 from slipping.

[0037] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
