Description

Technical Field

[0001] The present application relates to the technical field of inter-layer lifting, and in particular to an inter-layer lifting device for steel beam lifting and a lifting method thereof. Background Art

[0002] Steel beams are beams made of steel. Crane beams and working platform beams in factories, floor beams in multi-story buildings, purlins in roof structures, etc. can all be made of steel beams. With the development of society, steel beams have always been of great importance in construction due to their excellent bending and torsional stiffness.

[0003] At present, when constructing steel beams in multi-story buildings, the steel beams need to be transported first. Usually, two cranes are required to cooperate with each other to lift the steel beams placed on the ground and move them to the corresponding floors. Then the staff will remove the steel beams from the crane hooks and then transport them. Generally, this method is suitable for lifting and transporting one steel beam. When multiple steel beams need to be transported, the steel beams often need to be bundled and packed, and then lifted by the crane. However, this transportation method is more troublesome. During the lifting process, if the crane moves too fast, the hook and the steel beam are prone to shaking under the action of inertia, making the steel beam easy to hit the building or the staff. The moving speed needs to be reduced, thereby reducing the transportation efficiency of the steel beams. When multiple steel beams need to be transported, the steel beams need to be packed, which further reduces the transportation efficiency of the steel beams. Summary of the Invention

[0004] In order to improve the handling efficiency of steel beams, the present application provides an interlayer lifting device for steel beam hoisting and a hoisting method thereof.

[0005] On the one hand, the present application provides an interlayer lifting device for steel beam hoisting, which adopts the following technical solution:

[0006] The lifting mechanism is a kind of interlayer lifting device for lifting steel beams, comprising a fixed frame, the side wall of the fixed frame is slidably connected to the lifting frame, the top of the fixed frame is provided with a winding assembly for lifting the lifting frame, the top of the lifting frame is connected to the winding assembly, the inner wall of the lifting frame is slidably connected to the moving seat, the side wall of the lifting frame is provided with an opening for the moving seat to pass through, the side wall of the fixed frame is fixed with a push-pull driving member for driving the moving seat to move, the output end of the push-pull driving member is provided with a contact plate, and the side wall of the contact plate is provided with a grabbing assembly for engaging with the moving seat.

[0007] By adopting the above technical solution, when the steel beam needs to be transported to other floors, the winding component can be used to lower the lifting frame close to the bottom of the fixed frame or move it to the floor where the steel beam is placed, and the push-pull driving member can be used to drive the contact plate to move, so that the contact plate is close to the moving seat, and the grabbing component is engaged with the moving seat, and the push-pull driving member is driven to move the moving seat out of the opening of the lifting frame. At this time, the steel beam can be placed on the top side of the moving seat. After the placement is completed, the push-pull driving member is driven to move the moving seat with the steel beam installed into the lifting frame, so that the grabbing component and the moving seat are released. The locking drive drives the push-pull drive member to move the contact plate and the grabbing assembly away from the moving seat, and the winding assembly moves the lifting frame to the floor where the steel beam is needed. The push-pull drive member is driven to bring the contact plate close to the moving seat, and the grabbing assembly is locked with the moving seat. The moving seat is moved out of the opening of the lifting frame to remove the steel beam, thereby completing the transportation of the steel beam without using a crane. Moreover, the lifting frame is not easy to collide with the building and the human body when it is lifted and lowered in the fixed frame. Therefore, the winding assembly can be used to speed up the movement speed of the lifting frame and improve the transportation efficiency of the steel beam.

[0008] Optionally, the grabbing assembly includes a grabbing drive, a sliding block and a clamping block arranged on the side wall of the contact plate, the sliding block is slidingly connected to the side wall of the contact plate, the output end of the grabbing drive is connected to the sliding block, the clamping block is fixed to the side wall of the sliding block, the side wall of the movable seat is provided with a plug-in slot for inserting the sliding block and the clamping block, and the side wall of the plug-in slot is provided with a clamping slot for clamping the clamping block.

[0009] By adopting the above technical solution, when the movable seat needs to be moved, the push-pull driving member can be driven to make the contact plate close to the vertical seat, and the sliding block and the card block are inserted into the plug-in slot. After the plug-in block and the card block are inserted, the grabbing driving member can be driven to make the plug-in block and the card block slide, so that the card block is stuck in the card slot, thereby fixing the contact plate and the movable seat, and the push-pull driving member can be driven to move the movable seat.

[0010] Optionally, an electromagnet is provided on a side of the contact plate close to the movable seat, the electromagnet is connected to an external power supply, and an iron block is provided on the inner wall of the movable seat.

[0011] By adopting the above technical solution, when the push-pull driving member is driven close to the movable seat, the electromagnet can be energized to attract the iron block, so that the movable seat and the contact plate are brought close to each other, thereby reducing the situation where the contact plate knocks the movable seat away.

[0012] Optionally, the bottom of the movable seat is rotatably connected to a first pulley and a second pulley, the inner wall of the lifting frame is provided with a sliding rail, the second pulley is slidingly matched with the sliding rail, and the bottom side wheel surface of the first pulley is in contact with the inner bottom wall of the lifting frame.

[0013] By adopting the above technical solution, the winding drive component is driven to move the lifting frame to the floor where the steel beam is needed, and the push-pull drive component pushes the moving seat out of the opening of the lifting frame. The first pulley can contact the surface of the floor where the steel beam is needed and slide, and the sliding rail can limit and guide the second pulley.

[0014] Optionally, one end of the sliding rail close to the opening of the lifting frame is rotatably connected to a rotating rail, the bottom side of the rotating rail is flush with the inner bottom wall of the lifting frame, the side wall of the lifting frame is provided with a rotating driving member for driving the rotating rail to rotate, the side wall of the rotating rail is provided with an extended edge, the output end of the rotating driving member is connected to the extended edge, and the rotating rail is located between the opening of the lifting frame and the first pulley.

[0015] By adopting the above technical solution, after the lifting frame moves to the floor where the steel beam is required, the rotating driving member can be driven to pull the extending edge and the rotating rail to rotate the rotating rail, so that the end of the rotating rail abuts the end of the sliding rail, and the extending direction of the rotating rail is consistent with the extending direction of the sliding rail. In this state, the end of the rotating rail away from the sliding rail is located outside the opening of the lifting frame, so that the bottom surface of the rotating rail abuts against the level of the floor, and the push-pull driving member pushes the moving seat out of the opening of the lifting frame, so that the first pulley contacts the level of the floor, so that when the moving seat moves out of the lifting frame opening, the first pulley at the bottom of the moving seat abuts against the level of the floor and the inner bottom wall of the lifting frame respectively, thereby reducing the situation where the first pulley moved out of the lifting frame opening is suspended in the air, and making it difficult for the inner bottom wall of the lifting frame to be deformed due to excessive pressure.

[0016] Optionally, a baffle is inserted into the side wall of the lifting frame, and the baffle is slidingly connected to the lifting frame. The side wall of the lifting frame is provided with a sliding drive component, the output end of the sliding drive component is connected to the baffle, and the bottom side of the baffle is flush with the bottom side of the rotating rail.

[0017] By adopting the above technical solution, after the lifting frame moves to the floor where the steel beam is required, the sliding drive component can be driven to make the baffle slide out of the side wall of the lifting frame, and the winding drive component can be driven to adjust the height position of the lifting frame so that the bottom side of the baffle abuts against the surface of the floor. At this time, the rotating drive component can be driven to make the bottom surface of the rotating rail abut against the surface of the floor, thereby reducing the collision between the rotating rail and the floor.

[0018] Optionally, a placement seat is provided on the movable seat, a mounting block is fixed to the bottom of the placement seat, the mounting block is plugged into the top side of the movable seat, a plug-in rod is plugged into the side wall of the movable seat, and the plug-in rod passes through the side wall of the mounting block.

[0019] By adopting the above technical solution, the placement seat can be plugged into the top side of the horizontal seat through the mounting block, and the connecting rod can be inserted into the side wall of the movable seat so that the connecting rod passes through the side wall of the mounting block, so that the placement seat and the movable seat can be fixed. When the steel beam needs to be placed, the steel beam can be placed on the top side of the placement seat. After moving the movable seat to the floor where the steel beam is needed, the connecting rod can be pulled out to move the placement seat out of the mounting seat, so that the steel beam can be moved out at one time.

[0020] Optionally, the side wall of the fixed frame is rotatably connected to a connecting seat, and the connecting seat is rotatably connected to a rotating wheel at one end away from the fixed frame. The side wall of the fixed frame is provided with a flipping drive component, and the output end of the flipping drive component is connected to the connecting seat. The bottom of the fixed frame is provided with a lifting drive component, and the lifting drive component is provided with a support seat at one end away from the fixed frame. The side wall of the support seat is provided with a avoidance groove for the rotating wheel to pass through, and the support seat is slidably matched with the fixed frame.

[0021] By adopting the above technical solution, when the fixed frame needs to be moved, the fixed frame can be slid by the rotating wheel. When the fixed frame is moved to a position where the steel beam can be transported, the jacking drive member is driven to lower the support seat, so that the rotating wheel passes through the avoidance groove, the support seat is in contact with the ground, the fixed frame is jacked up, and the rotating wheel is away from the ground, thereby fixing the fixed frame.

[0022] Optionally, the side wall of the fixed frame is slidably connected to a limit plate, and the side wall of the fixed frame is provided with a limit driving component for driving the limit plate to move into or away from the moving path of the lifting frame, and the output end of the limit driving component is connected to the limit block.

[0023] By adopting the above technical solution, before the lifting frame rises, the limit driving component can be driven to drive the limit plate to move, so that the limit plate is away from the moving path of the lifting frame. After the lifting frame is lifted, the limit plate is moved into the moving path of the lifting frame, so that the limit plate is moved to directly below the lifting frame, thereby reducing the situation where the lifting frame suddenly falls and causes serious damage.

[0024] On the other hand, the present application provides a hoisting method, which adopts the following technical solution:

[0025] A hoisting method comprises the following steps:

[0026] s1: The lifting frame is raised or lowered to the floor where the steel beam is placed through the reeling component;

[0027] s2: The grabbing assembly engages with the movable seat, driving the push-pull driving member to move the movable seat out of the opening of the lifting frame;

[0028] s3: Place the steel beam on the moving seat;

[0029] s4: driving the push-pull driving member to move the movable base into the lifting frame, and driving the push-pull driving member to separate the grabbing assembly from the movable base;

[0030] s5: Move the lifting frame to the floor where the steel beam is required through the reeling assembly;

[0031] s6: drive the push-pull driving member to engage the grabbing assembly with the moving seat, drive the push-pull driving member to move the moving seat out of the opening of the lifting frame, and remove the steel beam placed on the moving seat.

[0032] By adopting the above technical solution, the steel beams are lifted and transported by using a winding assembly, a lifting frame, a movable seat push-pull drive, and a grabbing assembly instead of a crane. The lifting frame is not likely to collide with buildings and people when it is lifted and lowered in a fixed frame. Therefore, the winding assembly can be used to speed up the movement speed of the lifting frame and improve the transportation efficiency of the steel beams.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. When the steel beam needs to be transported to another floor, the winding assembly can be used to lower the lifting frame close to the bottom of the fixed frame or move it to the floor where the steel beam is placed. The push-pull drive member can drive the contact plate to move so that the contact plate is close to the moving seat, and the grabbing assembly can be engaged with the moving seat. The push-pull drive member can be driven to move the moving seat out of the opening of the lifting frame. At this time, the steel beam can be placed on the top side of the moving seat. After the placement is completed, the push-pull drive member can be driven to move the moving seat with the steel beam into the lifting frame, so that the grabbing assembly and the moving seat are released. The push-pull drive member is driven to move the contact plate and the grabbing assembly away from the moving seat, and the reeling assembly moves the lifting frame to the floor where the steel beam is needed. The push-pull drive member is driven to move the contact plate and the moving seat closer, and the grabbing assembly is engaged with the moving seat. The moving seat is moved out of the opening of the lifting frame to remove the steel beam, thereby completing the transportation of the steel beam without using a crane. Moreover, the lifting frame is less likely to collide with buildings and people when it is raised and lowered in the fixed frame. Therefore, the reeling assembly can be used to speed up the movement of the lifting frame and improve the efficiency of steel beam transportation.

[0035] 2. When the movable seat needs to be moved, the push-pull driving member can be driven to move the contact plate close to the vertical seat, and the sliding block and the clamping block can be inserted into the plug-in slot. After the plug-in block and the clamping block are inserted, the grab driving member can be driven to slide the plug-in block and the clamping block, so that the clamping block is clamped into the clamping slot, thereby fixing the contact plate and the movable seat. The push-pull driving member can be driven to move the movable seat;

[0036] 3. After the lifting frame moves to the floor where the steel beam is required, the rotating driving member can be driven to pull the extending edge and the rotating rail to rotate the rotating rail, so that the end of the rotating rail abuts the end of the sliding rail, and the extending direction of the rotating rail is consistent with the extending direction of the sliding rail. In this state, the end of the rotating rail away from the sliding rail is located outside the opening of the lifting frame, so that the bottom surface of the rotating rail can abut against the level of the floor, and the push-pull driving member pushes the moving seat out of the opening of the lifting frame to make the first pulley contact with the level of the floor, so that in the process of the moving seat moving out of the lifting frame opening, the first pulley at the bottom of the moving seat abuts against the level of the floor and the inner bottom wall of the lifting frame respectively, thereby reducing the situation where the first pulley moved out of the lifting frame opening is suspended in the air, and making it difficult for the inner bottom wall of the lifting frame to be deformed due to excessive pressure.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-4 This application is described in further detail.

[0044] An embodiment of the present application discloses an inter-layer lifting device for lifting steel beams.

[0045] Reference Figure 1 and Figure 2 An interlayer lifting device for steel beam hoisting includes a fixed frame 1, the inner side wall of the fixed frame 1 is slidably connected to a lifting frame 2, the lifting frame 2 slides in the vertical direction, the top of the fixed frame 1 is connected to a winding assembly, the top of the lifting frame 2 is connected to the winding assembly, and the winding assembly can make the lifting frame 2 move up and down, the inner bottom wall of the lifting frame 2 is slidably connected to a moving seat 3, the moving seat 3 slides in the horizontal direction, the side wall of the lifting frame 2 is provided with an opening, the opening of the lifting frame 2 is for the moving seat 3 to pass through, and the moving seat 3 can pass through the opening Slide out or slide in the lifting frame 2, a push-pull drive member 4 is fixed on the side of the fixed frame 1 away from the opening of the lifting frame 2, the push-pull drive member 4 is a cylinder, the push-pull drive member 4 is placed horizontally, and the number of push-pull drive members 4 is consistent with the number of floors that require steel beams in the building. In this embodiment, the number of push-pull drive members 4 is two, and the push-pull drive members 4 are arranged in the vertical direction. A contact plate 41 is fixed to the output end of the push-pull drive member 4, and a grabbing assembly is provided on the side wall of the contact plate 41, which can be snapped into contact with the moving seat 3.

[0046] When the steel beam needs to be transported to other floors, the fixed frame 1 is moved to the side of the building where the wall has not been built. The winding assembly can be used to lower the lifting frame 2 close to the bottom of the fixed frame 1 or move it to the floor where the steel beam is placed, so that the push-pull driving member 4 drives the contact plate 41 to move, so that the side of the contact plate 41 facing away from the push-pull driving member 4 is close to the moving seat 3, and the grabbing assembly is engaged with the moving seat 3. After the engagement is completed, the push-pull driving member 4 is driven to move the moving seat 3 toward the opening side of the lifting frame 2 and move the moving seat 3 out of the opening of the lifting frame 2. At this time, the steel beam can be placed on the top side of the moving seat 3. After the placement is completed, the push-pull driving member 4 is driven to move the moving seat 3 equipped with the steel beam into the lifting frame 2, so that the grabbing assembly is released from the moving seat 3, and the push-pull driving member 4 is driven to move the contact plate 41 and the grabbing assembly away from the moving seat 3. The winding assembly makes the lifting frame 2 rise or fall, and moves the lifting frame 2 to the floor where the steel beam is needed. The push-pull drive member 4 is driven to make the contact plate 41 close to the moving seat 3, and the grabbing assembly is engaged with the moving seat 3. The moving seat 3 is moved out of the opening of the lifting frame 2 to remove the steel beam, thereby completing the transportation of the steel beam without using a crane. Moreover, the lifting frame 2 is not easy to collide with the building and the human body when it is lifted and lowered in the fixed frame 1. Therefore, the moving speed of the lifting frame 2 can be accelerated by the winding assembly, and the transportation efficiency of the steel beam is improved. When multiple steel beams need to be transported, multiple steel beams can be placed on the moving seat 3. It is simple and convenient, and the packaging step is eliminated, further improving the transportation efficiency. Moreover, the push-pull drive member 4 does not need to follow the lifting frame 2 to rise and fall, so the collision of the push-pull drive member 4 with other equipment can be avoided as much as possible.

[0047] Reference Figure 1The winding assembly includes a winding drive 11, a winding wheel 12, a pulley wheel 13 and a winding rope 14. The winding drive 11 is a servo motor. The winding drive 11 is fixed to the top side of the fixed frame 1. The winding wheel 12 is rotatably connected to the top side of the fixed frame 1. The pulley wheel 13 is rotatably connected to the top side of the fixed frame 1. One end of the winding rope 14 is fixed to the side wall of the winding wheel 12, and the other end is fixed to the top side of the lifting frame 2. The winding rope 14 is draped on the side wall of the pulley wheel 13. The winding rope 14 is a steel rope. The output end of the winding drive 11 is connected to the winding wheel 12.

[0048] When the lifting frame 2 needs to be raised or lowered, the winding drive member 11 can be driven to rotate the winding wheel 12, and the winding rope 14 can be wound into or moved out of the winding wheel 12, thereby raising or lowering the lifting frame 2, and the height position of the lifting frame 2 can be adjusted.

[0049] Reference Figure 2 and Figure 3 The grabbing assembly includes a grabbing drive member 42, a sliding block 43 and a clamping block 44 arranged on the side wall of the contact plate 41. The grabbing drive member 42 is a bidirectional cylinder. The grabbing drive member 42 is fixed to the side of the contact plate 41 close to the push-pull drive member 4. The sliding block 43 is slidingly connected to the contact plate 41. The sliding direction of the sliding block 43 is consistent with the driving direction of the grabbing drive member 42. The output end of the grabbing drive member 42 is connected to the sliding block 43. The sliding block 43 passes through the side of the contact plate 41 away from the push-pull drive member 4. The clamping block 44 The connecting block 44 is fixed to the side wall of the sliding block 43. The sliding block 43 and the clamping block 44 form an "L" shape. The contact plate 41 is located between the clamping block 44 and the push-pull driving member 4. The movable seat 3 includes a horizontal seat 301 and a vertical seat 302. The horizontal seat 301 is slidingly connected to the inner bottom wall of the lifting frame 2. The side wall of the vertical seat 302 is provided with a plug-in groove 303. The sliding block 43 and the clamping block 44 can be inserted into the plug-in groove 303. The side wall of the plug-in groove 303 is provided with a clamping groove 304. The clamping block 44 can be inserted into the clamping groove 304.

[0050] When it is necessary to move the movable seat 3, the push-pull drive member 4 can be driven to make the contact plate 41 close to the vertical seat 302, and the sliding block 43 and the clamping block 44 can be inserted into the plug-in slot 303. After the plug-in block and the clamping block 44 are inserted, the grabbing drive member 42 can be driven to make the plug-in block and the clamping block 44 slide, so that the clamping block 44 is clamped into the clamping slot 304, thereby fixing the contact plate 41 and the movable seat 3. At this time, the push-pull drive member 4 can be driven to move the movable seat 3. When it is necessary to disengage the contact plate 41 from the movable seat 3, the grabbing drive member 42 is driven to make the plug-in block and the clamping block 44 slide, so that the clamping block 44 is disengaged from the clamping slot 304. By driving the push-pull drive member 4, the contact plate 41 can be disengaged from the movable seat 3, and the plug-in block and the clamping block 44 can be disengaged from the plug-in slot 303.

[0051] Reference Figure 1 and Figure 3 An electromagnet 45 is provided on the side of the contact plate 41 close to the movable seat 3, and the electromagnet 45 is connected to an external power supply. An iron block is provided inside the vertical seat 302. When the push-pull driving member 4 is driven close to the movable seat 3, the electromagnet 45 can be energized to attract the iron block, so that the movable seat 3 is close to the contact plate 41, which can reduce the situation where the push-pull driving member 4 drives the contact plate 41 close to the movable seat 3 and knocks the movable seat 3 away.

[0052] Reference Figure 2 and Figure 4 The bottom of the movable base 3 is rotatably connected to the first pulley 31 and the second pulley 32. The inner bottom wall of the lifting frame 2 is provided with a sliding rail 33. The extension direction of the sliding rail 33 is consistent with the sliding direction of the movable base 3. The second pulley 32 and the sliding rail 33 are in sliding cooperation. The bottom side plane of the sliding rail 33 is tangent to the bottom side curved surface of the first pulley 31. The bottom side wheel surface of the first pulley 31 is in contact with the inner bottom wall of the lifting frame 2. There are four first pulleys 31 and they are distributed at the four corners of a rectangle.

[0053] The winding drive member 11 is driven to move the lifting frame 2 to the floor where the steel beam is needed. The push-pull drive member 4 pushes the movable base 3 out of the opening of the lifting frame 2. The first pulley 31 can contact the surface of the floor where the steel beam is needed and slide. The sliding rail 33 can limit and guide the second pulley 32, so that the movable base 3 is not easily shifted sideways.

[0054] One end of the sliding rail 33 close to the opening of the lifting frame 2 is rotatably connected to the rotating rail 34. The rotation axis between the sliding rail 33 and the rotating rail 34 extends in the vertical direction. The rotation axis between the sliding rail 33 and the rotating rail 34 is close to the first pulley 31. The second pulley 32 can slide in the rotating rail 34. The bottom side of the rotating rail 34 is flush with the inner bottom wall of the lifting frame 2. The side wall of the lifting frame 2 is rotatably connected to a rotating drive member 35. The rotating drive member 35 is a cylinder. The side wall of the rotating rail is provided with an extended edge 341. The output end of the rotating drive member 35 is rotatably connected to the extended edge 341. The rotating drive member 35 can drive the rotating rail 34 to rotate. The rotating rail 34 is located between the opening of the lifting frame 2 and the first pulley 31.

[0055] After the lifting frame 2 moves to the floor where the steel beam is needed, the rotating drive member 35 can be driven to pull the extension edge 341 and the rotating rail 34 to rotate the rotating rail 34 so that the end of the rotating rail 34 abuts against the end of the sliding rail 33, and the extension direction of the rotating rail 34 is consistent with the extension direction of the sliding rail 33. In this state, the end of the rotating rail 34 away from the sliding rail 33 is located outside the opening of the lifting frame 2, so that the bottom surface of the rotating rail 34 can abut against the layer of the floor, and the push-pull drive member 4 pushes the moving seat 3 out The opening of the lifting frame 2 causes the first pulley 31 to contact the surface of the floor. When the movable base 3 moves out of the opening of the lifting frame 2, the first pulley 31 at the bottom of the movable base 3 abuts against the surface of the floor and the inner bottom wall of the lifting frame 2, respectively. This reduces the possibility of the first pulley 31 being suspended in the air when moving out of the opening of the lifting frame 2, and prevents the inner bottom wall of the lifting frame 2 from being deformed due to excessive pressure. When the second pulley 32 slides on the rotating rail 34, the rotating rail 34 can apply pressure to the surface of the floor, thereby reducing the force on the lifting frame 2.

[0056] When the lifting frame 2 needs to be raised or lowered, the rotating driving member 35 can be driven to stagger the rotating rail 34 and the sliding rail 33, thereby avoiding the rotating rail 34 from colliding with the building as much as possible, and the rotating rail 34 can be blocked between the opening of the lifting frame 2 and the first pulley 31, and close to the wheel surface of the first pulley 31. Due to the high weight of the steel beam itself, the lifting frame 2 may shake during the lifting process, thereby causing the moving seat 3 to slide through the first pulley 31, causing the moving seat 3 and the steel beam to slide out of the opening of the lifting frame 2, causing the moving seat 3 or the steel beam to collide with the building floor and be damaged, or even fall, which can easily lead to an accident. The rotating rail 34 can limit the first pulley 31, making it difficult for the moving seat 3 to slide during the lifting process, so that the moving seat 3 and the steel beam stay inside the lifting frame 2, thereby improving safety and lifting stability.

[0057] The side wall of the lifting frame 2 is provided with a baffle 21, which is plugged into the open side of the lifting frame 2. The baffle 21 is in the shape of a straight rod and is slidingly connected to the lifting frame 2. A sliding drive member 22 is embedded in the side wall of the opening side of the lifting frame 2. The sliding drive member 22 is a cylinder. The output end of the sliding drive member 22 is connected to the baffle 21, and the bottom side of the baffle 21 is flush with the bottom side of the rotating rail 34.

[0058] After the lifting frame 2 moves to the floor where the steel beam is required, the sliding drive member 22 can be driven to make the blocking bar 21 slide out of the side wall of the lifting frame 2, and the winding drive member 11 can be driven to adjust the height position of the lifting frame 2 so that the bottom side of the blocking bar 21 abuts against the surface of the floor. At this time, the rotating drive member 35 can be driven to make the bottom surface of the rotating rail 34 abut against the surface of the floor, thereby reducing the collision between the rotating rail 34 and the floor, reducing vibration, and protecting the rotating rail 34.

[0059] A placement seat 36 is provided on the top of the movable seat 3, and a mounting block 361 is fixed to the bottom of the placement seat 36. The mounting block 361 is plugged into the top side of the movable seat 3, and the mounting block 361 can be plugged into the top side of the horizontal seat 301. The side wall of the movable seat 3 is plugged into a plug-in rod 37, and the plug-in rod 37 passes through the side wall of the mounting block 361.

[0060] Due to the heavy weight of the steel beam, when the steel beam is moved to the required floor through the lifting frame 2 and the moving seat 3, the steel beams need to be unloaded one by one. The weight of the steel beam itself is large, and the process of unloading the steel beam is time-consuming and labor-intensive. Therefore, when the steel beam needs to be transported to the floor where the steel beam is needed, the placement seat 36 can be plugged into the top side of the horizontal seat 301 through the mounting block 361, and the plug-in rod 37 can be inserted into the side wall of the moving seat 3 so that the plug-in rod 37 is inserted into and passes through the side wall of the mounting block 361, so that the placement seat 36 and the moving seat 3 can be fixed. The mounting block 361 makes it difficult for the placement seat 36 to move in the horizontal direction, and the plug-in rod 37 makes it difficult for the placement seat 36 to move in the vertical direction. After the placement seat 36 is fixed to the moving seat 3 by the mounting block 361 and the connecting rod 37, it is not easy to move, so the steel beam is not easy to fall, thereby improving safety.

[0061] A groove 362 is provided on the side wall of the placement seat 36, and the groove 362 is located at the bottom of the placement seat 36. When moving the mounting seat, the fork of a forklift can be inserted into the groove 362 to move the placement seat 36 together with the steel beam, thereby improving the handling efficiency. The top side of the placement seat 36 is recessed. When the steel beam needs to be placed on the top side of the placement seat 36, the steel beam can be placed in the recessed portion of the top side of the placement seat 36, thereby reducing the displacement of the steel beam and improving the stability and safety of the handling process.

[0062] Reference Figure 1The side wall of the fixed frame 1 is rotatably connected to a connecting seat 151. The connecting seat 151 is set in an L-shaped rod shape. The connecting seat 151 includes a straight rod portion and a folding rod portion. The side of the straight rod portion abuts against the side wall of the fixed frame 1, and the top of the folding rod portion abuts against the bottom side of the fixed frame 1. The connecting seat 151 is close to the bottom of the fixed frame 1. The side wall of the fixed frame 1 is fixed with a flip driving member 15. The flip driving member 15 is a servo motor. The output end of the flip driving member 15 is connected to the connecting seat 151 Then, the connecting seat 151 is rotatably connected to the end away from the fixed frame 1 with a rotating wheel 152, and a jacking drive member 16 is provided at the bottom of the fixed frame 1. The jacking drive member 16 is a jack, and a support seat 17 is provided at the end of the jacking drive member 16 away from the fixed frame 1. A sliding plate 171 is fixed to the side wall of the support seat 17. The sliding plate 171 slides with the fixed frame 1, and the support seat 17 slides in the vertical direction. The side wall of the support seat 17 is provided with an avoidance groove for the rotating wheel 152 to pass through.

[0063] When the fixed frame 1 needs to be moved, the fixed frame 1 can be slid through the rotating wheel 152. When the fixed frame 1 is moved to a position where the steel beam can be transported, the jacking drive member 16 is driven to lower the support seat 17, so that the rotating wheel 152 passes through the avoidance groove, so that the support seat 17 contacts the ground, and the fixed frame 1 is jacked up, so that the rotating wheel 152 is away from the ground, thereby fixing the fixed frame 1.

[0064] When the relative height between the lifting frame 2 and the floor needs to be adjusted, the lifting drive member 16 can be driven to lift the fixed frame 1 as a whole, thereby adjusting the height of the lifting frame 2. The flip drive member 15 can drive the connecting seat 151 to rotate upward, so that the connecting seat 151 and the rotating wheel 152 are away from the ground, thereby expanding the height adjustment range of the fixed frame 1 and the lifting frame 2.

[0065] The side wall of the fixed frame 1 is slidably connected to the limit plate 18, and the limit plate 18 slides in the horizontal direction. The side wall of the fixed frame 1 is provided with a limit driving component 19, and the limit driving component 19 is a cylinder. The limit driving component 19 can drive the limit plate 18 to move into or away from the moving path of the lifting frame 2, and the output end of the limit driving component 19 is connected to the limit block.

[0066] Before the lifting frame 2 rises, the limit driving member 19 can be driven to drive the limit plate 18 to move so that the limit plate 18 is away from the moving path of the lifting frame 2. After the lifting frame 2 is lifted, the limit plate 18 is moved into the moving path of the lifting frame 2 and is moved to directly below the lifting frame 2, thereby reducing the situation where the lifting frame 2 suddenly falls and causes serious damage.

[0067] The present application also discloses a hoisting method, which uses the above-mentioned interlayer lifting device for steel beam hoisting, and includes the following steps:

[0068] s1: The lifting frame 2 is raised or lowered to the floor where the steel beam is placed through the winding component;

[0069] s2: The grabbing assembly engages with the movable base 3, driving the push-pull driving member 4 to move the movable base 3 out of the opening of the lifting frame 2;

[0070] s3: Place the steel beam on the moving seat 3;

[0071] s4: driving the push-pull driving member 4 to move the movable seat 3 into the lifting frame 2, and driving the push-pull driving member 4 to separate the grabbing assembly from the movable seat 3;

[0072] s5: Move the lifting frame 2 to the floor where the steel beam is required through the winding assembly;

[0073] s6: Drive the push-pull driving member 4 to engage the grabbing assembly with the moving seat 3, drive the push-pull driving member 4 to move the moving seat 3 out of the opening of the lifting frame 2, and remove the steel beam placed on the moving seat 3.

[0074] The embodiment of the present application is an inter-layer lifting device for steel beam hoisting and the implementation principle of the lifting method thereof is as follows: when it is necessary to transport the steel beam, the fixed frame 1 is moved to the side of the building body where the wall has not been built, the winding drive member 11 can be made to drive the lifting frame 2 to descend close to the bottom of the fixed frame 1 or move to the floor where the steel beam is placed, and the push-pull drive member 4 drives the contact plate 41 to move, so that the side of the contact plate 41 facing away from the push-pull drive member 4 is close to the moving seat 3, and the grabbing drive member 42 is driven to make the clamping fastener clamped with the moving seat 3. After the clamping is completed, the push-pull drive member 4 is driven to move the moving seat 3 toward the opening side of the lifting frame 2 and move the moving seat 3 out of the opening of the lifting frame 2. At this time, the steel beam can be placed on the top side of the placement seat 36. After the placement is completed, the push-pull drive member 4 is driven to move the moving seat equipped with the steel beam. The movable seat 3 moves into the lifting frame 2, and the grabbing driving member 42 is driven to release the engagement of the clamping block 44 with the moving seat 3. The push-pull driving member 4 is driven to move the contact plate 41 away from the moving seat 3, and the winding driving member 11 drives the lifting frame 2 to rise or fall, so that the lifting frame 2 moves to the floor where the steel beam is needed. The push-pull driving member 4 is driven to move the contact plate 41 close to the moving seat 3, and the clamping block 44 is clamped with the moving seat 3. The moving seat 3 is moved out of the opening of the lifting frame 2, and the plug-in rod 37 is pulled out. The placement seat 36 can be removed together with the steel beam, thereby completing the transportation of the steel beam without using a crane. In addition, the lifting frame 2 is not likely to collide with the building or the human body when it is lifted and lowered in the fixed frame 1. Therefore, the moving speed of the lifting frame 2 can be accelerated by the winding assembly, thereby improving the transportation efficiency of the steel beam.

[0075] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and do not limit the scope of protection of the present application in turn. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
