Description

Technical Field

[0001] This application relates to the field of steel reinforcement hoisting, and in particular to a precision hoisting device for steel reinforcement cages. Background Technology

[0002] Reinforcing steel cages are pre-assembled and are commonly found in brick-concrete construction. A reinforcing steel cage generally refers to a three-dimensional assembly of reinforcing steel bars, such as those within beams and columns. Before hoisting, it is necessary to check whether the spacing and row spacing meet the requirements.

[0003] In related technologies, the hoisting structure for steel reinforcement cages mainly includes a crane, a hoisting platform, and hooks. The hoisting platform is equipped with a lifting ring that cooperates with the hook of the crane. The hooks are located on the side of the hoisting platform away from the lifting frame. When it is necessary to move the steel reinforcement cage, the operator connects the hooks to the steel reinforcement cage, and then the operator can start the crane to move the steel reinforcement cage.

[0004] Regarding the aforementioned technologies, the inventors discovered that when the steel reinforcement cage is lifted to a high altitude, the wind force causes the steel reinforcement cage to sway, which in turn causes the suspended platform to sway, reducing the stability of the connection between the suspended platform and the crane and posing a significant safety hazard. Therefore, improvements are needed. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a precise hoisting device for steel reinforcement cages.

[0006] This application provides a precision hoisting device for steel reinforcement cages, which adopts the following technical solution:

[0007] A precision hoisting device for reinforcing steel cages, connected to a crane, includes a hoisting plate and a balance plate. The hoisting plate is connected to the crane and is spherically hinged to the balance plate. A hoisting mechanism for hoisting the reinforcing steel cage is provided on the side of the balance plate away from the hoisting plate. An angle sensor is provided on the hoisting plate. A fixing groove is formed vertically on the side of the hoisting plate near the balance plate, and a fixing column is slidably connected in the fixing groove. A connecting groove is formed vertically on the side of the balance plate near the hoisting plate, and the fixing column abuts against the inner wall of the connecting groove. A triggering component for controlling the fixing column is provided in the fixing groove.

[0008] By adopting the above technical solution, operators connect the reinforcing steel cage to the hoisting mechanism, then use a crane to perform a trial lift of the reinforcing steel cage. The positions of the hoisting mechanism and the reinforcing steel cage are then adjusted based on the detection values ​​from the tilt sensor. When the balance plate is horizontal, the trigger component controls the fixing column to insert into the connecting slot. The fixing column provides a limit to the balance plate, making it less prone to tilting during subsequent movement. This improves the stability of the reinforcing steel cage during movement, allowing operators to move the reinforcing steel cage to the designated position more accurately.

[0009] Preferably, the suspended platform is provided with a stabilizing component, which includes a stabilizing frame, a stabilizing cylinder, and a stabilizing rope. The stabilizing frame is disposed on the suspended platform, the stabilizing cylinder is rotatably connected to the stabilizing frame, the stabilizing rope is wound around the stabilizing cylinder, and the end of the stabilizing rope away from the stabilizing cylinder is connected to a balance plate. A torsion spring is provided on the rotating shaft of the stabilizing cylinder, one end of the torsion spring is connected to the stabilizing cylinder, and the other end is connected to the stabilizing frame. The suspended platform is provided with a locking component for locking the stabilizing cylinder, and the end of the locking component away from the suspended platform is connected to a fixed column.

[0010] By adopting the above technical solution, when the operator adjusts the position of the steel reinforcement cage and the hoisting mechanism, the balance plate pulls the stabilizing rope, which in turn drives the stabilizing cylinder to rotate, while the torsion spring is in a compressed state. When the balance plate is in a horizontal state, under the action of the torsion spring's rebound force, the stabilizing cylinder resets and rewinds the stabilizing rope. The trigger component then controls the fixing column to insert into the connecting slot. At the same time, the fixing column drives the locking component to activate, which locks the rotating shaft of the stabilizing cylinder, making it less likely for the stabilizing cylinder to rotate during subsequent movement. This ensures that the stabilizing rope connects the hoisting plate and the balance plate more stably, further reducing the possibility of the balance plate tilting during subsequent movement, thereby further improving the stability of the steel reinforcement cage during movement.

[0011] Preferably, the locking assembly includes a locking frame, a locking plate, and a pull rope. The locking frame is mounted on the hanging plate, and the locking plate is slidably connected to the locking frame. A locking block is provided at the end of the locking plate away from the locking frame. A locking groove that mates with the locking block is provided on the rotating shaft of the stabilizing cylinder. A mating groove communicating with the fixing groove is provided in the vertical direction on the hanging plate. One end of the pull rope is connected to the locking plate, and the other end passes through the mating groove and enters the fixing groove and is connected to the fixing post. A first roller and a second roller are provided on the locking frame, and the pull rope is wound around the first roller and the second roller in sequence.

[0012] By adopting the above technical solution, during the process of inserting the fixed column into the connecting groove, the fixed column drives the pull rope to move. The pull rope drives the second roller and the first roller to rotate in sequence. The end of the pull rope away from the first roller then drives the locking plate and the locking block to move towards the stabilizing cylinder. When the locking block abuts against the inner wall of the locking groove, it completes the limitation of the stabilizing cylinder, making it difficult for the stabilizing cylinder to rotate, so that the stabilizing rope can connect the hanging plate and the balance plate more stably.

[0013] Preferably, the triggering component includes an electromagnet and a triggering spring. The electromagnet is disposed at the bottom of the fixed groove, and one end of the triggering spring is connected to the electromagnet and the other end is connected to the fixed post.

[0014] By adopting the above technical solution, when the balance plate is not in a horizontal state, the electromagnet is in the open state and attracts the fixed column, and the trigger spring is in the compressed state. When the balance plate is in a horizontal state, under the action of the return force of the trigger spring, the fixed column is inserted into the connecting groove, thus facilitating the control of the movement of the fixed column.

[0015] Preferably, the hoisting mechanism includes a first hoisting component and a second hoisting component. Both the first hoisting component and the second hoisting component include a hoisting box and a hanger. The hoisting box reciprocates along the length of the balance plate. The hanger is located on the side of the hoisting box away from the balance box. The hanger is provided with a limiting component for fixing the reinforcing steel frame.

[0016] By adopting the above technical solution, operators use a crane to move the lifting platform and balance plate to the rebar cage, bringing the rebar cage into contact with the lifting frame. The operators then use limiting components to restrain the rebar cage, preventing it from easily separating from the lifting frame and facilitating a more stable transfer of the rebar cage. Furthermore, the reciprocating lifting box allows operators to easily change the position between the lifting frame and the rebar cage, ensuring more even stress distribution on the rebar cage and reducing the possibility of deformation.

[0017] Preferably, the limiting component includes a pulley and a limiting plate. The hanger has a buffer groove in the vertical direction, a buffer column is slidably connected in the buffer groove, and a buffer spring is provided in the buffer groove. One end of the buffer spring is connected to the buffer column, and the other end is connected to the bottom of the buffer groove. The pulley is rotatably connected to the end of the buffer column away from the hanger. The hanger has a limiting groove in the vertical direction, and the limiting groove is arranged opposite to the buffer groove. The limiting plate is slidably connected in the limiting groove. An electric push rod is provided at the bottom of the limiting groove, and the output end of the electric push rod is connected to the limiting plate. The limiting plate and the pulley respectively abut against both sides of the reinforcing steel skeleton.

[0018] By adopting the above technical solution, when the operator changes the position between the reinforcing steel cage and the hanger, the reinforcing steel cage comes into contact with the pulley. At this time, the buffer column transmits the pressure on the pulley to the buffer spring, which absorbs part of the pressure, reducing the pressure of the pulley on the reinforcing steel cage and preventing damage to the reinforcing steel cage during the movement of the hanger. After the adjustment is completed, the operator activates the electric push rod, which moves the limiting plate toward the reinforcing steel cage. After the limiting plate abuts against the reinforcing steel cage, it completes the limitation of the reinforcing steel cage, making it difficult for the reinforcing steel cage to separate from the hanger and improving the stability when the operator moves the reinforcing steel cage.

[0019] Preferably, an auxiliary box is provided on the side of the balance plate away from the hanging plate, an auxiliary groove is provided in the auxiliary box, an auxiliary plate is slidably connected in the auxiliary groove, the end of the auxiliary plate away from the balance plate abuts against the steel reinforcement frame, and the auxiliary plate is controlled by an auxiliary component.

[0020] By adopting the above technical solution, during the movement of the steel reinforcement cage, the auxiliary component is activated and controls the auxiliary plate to move toward the steel reinforcement cage. When the auxiliary plate contacts the steel reinforcement cage, it further limits the movement of the steel reinforcement cage. At the same time, under the action of the auxiliary plate, the steel reinforcement cage is subjected to force more evenly, further reducing the possibility of deformation of the steel reinforcement cage.

[0021] Preferably, the auxiliary component includes a negative pressure plate, an auxiliary spring, a first connecting pipe, and a second connecting pipe. The negative pressure plate is slidably connected in the hoisting box and connected to the hanger. The hanger is slidably connected in the hoisting box. The auxiliary spring is vertically arranged in the hoisting box, with one end connected to the negative pressure plate and the other end connected to the inner wall of the hoisting box. The first connecting pipe communicates with the hoisting box. One end of the second connecting pipe communicates with the auxiliary groove and the other end communicates with the end of the first connecting pipe away from the hoisting box. A control plate is slidably connected in the second connecting pipe. An auxiliary gear is rotatably connected in the auxiliary groove. The shaft of the auxiliary gear is arranged horizontally. The control plate is provided with a first rack that meshes with the auxiliary gear. The auxiliary plate is provided with a second rack along its length that meshes with the auxiliary gear. A first negative pressure space is formed between the negative pressure plate and the control plate.

[0022] By adopting the above technical solution, when the crane controls the movement of the reinforcing steel cage, under the weight of the reinforcing steel cage and the hanger itself, the negative pressure plate moves away from the balance plate, and the auxiliary spring is in a stretched state. At this time, under the action of the first negative pressure space, the control plate is partially retracted into the second connecting pipe. The control plate then drives the first rack to move, the first rack drives the auxiliary gear to rotate, the auxiliary gear then drives the second rack to move, and the second rack drives the auxiliary plate to move towards the reinforcing steel cage, so that the auxiliary plate can further limit the movement of the reinforcing steel cage, thereby further improving the stability of the reinforcing steel cage during movement.

[0023] Preferably, the first connecting pipe is connected to a third connecting pipe at one end near the auxiliary box. The third connecting pipe is connected to the second connecting pipe. A diverter plate is rotatably connected at the connection point between the first connecting pipe and the second and third connecting pipes. The hanger is provided with a connecting assembly for controlling the diverter plate. The auxiliary box is provided with a reinforcing groove connected to the connecting groove. The fixing column extends into the reinforcing groove. The auxiliary box is provided with a stabilizing groove connected to the reinforcing groove in the horizontal direction. The stabilizing groove is connected to the third connecting pipe. A reinforcing plate is slidably connected in the third connecting pipe. A second negative pressure space is formed between the negative pressure plate and the reinforcing plate. The reinforcing plate is slidably connected to the inner wall of the stabilizing groove. A reinforcing hole is provided on the reinforcing plate. The fixing column abuts against the inner wall of the reinforcing hole. A reinforcing assembly for limiting the fixing column is provided on the inner wall of the reinforcing hole.

[0024] By adopting the above technical solution, when the balance plate is in a horizontal state, the operator controls the crane to transfer the reinforcing steel cage, at which point the diversion plate closes the second connecting pipe. Under the weight of the reinforcing steel cage and the hanger itself, the hanger drives the negative pressure plate to move away from the balance plate. Under the action of the second negative pressure space, the reinforcing plate gradually retracts into the third connecting pipe. Simultaneously, the hanger drives the connecting assembly to start, and the connecting assembly controls the diversion plate to gradually rotate towards the third connecting pipe. When the reinforcing hole is opposite the fixed column, under the action of the trigger spring's return force, the fixed column is engaged in the reinforcing hole. At the same time, the reinforcing assembly further fixes the fixed column, thereby further improving the connection stability between the hanger and the balance plate. After the fixed column is engaged in the reinforcing hole, the diversion plate closes the third connecting pipe, making it difficult for the reinforcing plate to move further, while also facilitating the subsequent further positioning of the reinforcing steel cage by the auxiliary plate.

[0025] Preferably, the reinforcement component includes a reinforcement column and a reinforcement spring. The inner wall of the reinforcement hole is provided with a first clearance groove. The reinforcement column is slidably connected in the first clearance groove. One end of the reinforcement spring is connected to the bottom of the first clearance groove and the other end is connected to the reinforcement column. The fixed column is provided with a second clearance groove, and the reinforcement column abuts against the inner wall of the second clearance groove.

[0026] By adopting the above technical solution, during the process of inserting the fixing column into the reinforcing hole, when the fixing column and the reinforcing column come into contact, the reinforcing column retracts into the first clearance groove, and the reinforcing spring is in a compressed state. When the reinforcing column is opposite to the second clearance groove, under the action of the rebound force of the reinforcing spring, the reinforcing column is stuck into the second clearance groove and abuts against the inner wall of the second clearance groove, thereby completing the fixing of the fixing column and further reducing the possibility of the fixing column separating from the balance plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up a fixed column, an inclination sensor and a triggering component, when the inclination sensor detects that the balance plate is in a horizontal state, the triggering component controls the fixed column to lock into the balance plate. At this time, the fixed column limits the balance plate, reducing the possibility of the balance plate tilting during subsequent movement and improving the stability when transferring the steel reinforcement cage.

[0029] 2. By setting up stabilizing and locking components, the stabilizing components improve the connection stability between the hanging plate and the balance plate, and the locking components make it difficult for the stabilizing components to continue working during the movement of the steel reinforcement cage, further improving the stability when transferring the steel reinforcement cage.

[0030] 3. By setting up auxiliary plates and auxiliary components, the auxiliary components control the auxiliary plates to further limit the movement of the steel reinforcement cage, making the steel reinforcement cage less prone to deformation during movement. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0044] This application discloses a precision hoisting device for steel reinforcement cages. (Refer to...) Figure 1 and Figure 2A precision hoisting device for a steel reinforcement cage includes a hoisting plate 1 and a balancing plate 2. The hoisting plate 1 is connected to a crane (not shown in the figure), and the hoisting plate 1 is spherically hinged to the balancing plate 2. A hoisting mechanism 3 for hoisting the steel reinforcement cage 9 is provided on the side of the balancing plate 2 away from the hoisting plate 1. A fixing groove 11 is formed vertically on the side of the hoisting plate 1 near the balancing plate 2, and a fixing column 111 is slidably connected in the fixing groove 11. A connecting groove 21 is formed vertically on the side of the balancing plate 2 near the hoisting plate 1, and the fixing column 111 is inserted into the connecting groove 21. A triggering component 12 for controlling the fixing column 111 is provided in the fixing groove 11, and an angle sensor 112 is fixed on the fixing column 111. The operator connects the hoisting mechanism 3 to the steel reinforcement cage 9, and then observes the tilt angle of the balance plate 2 through the tilt sensor 112. When the balance plate 2 is in a horizontal state, the trigger component 12 starts and controls the fixing column 111 to insert into the connecting groove 21. At this time, the fixing column 111 provides a limit for the balance plate 2, making it less likely for the balance plate 2 to tilt during subsequent movement, thereby improving the stability when hoisting the steel reinforcement cage 9, so that the steel reinforcement cage 9 can be transported to the designated position more stably.

[0045] Reference Figure 1 and Figure 2 The trigger assembly 12 includes an electromagnet 121 and a trigger spring 122. The electromagnet 121 is fixed to the bottom of the fixing groove 11, and the trigger spring 122 is disposed in the fixing groove 11, with one end of the trigger spring 122 fixed to the electromagnet 121 and the other end fixed to the fixing column 111. When the operator adjusts the position of the hoisting mechanism 3 and the steel reinforcement frame 9, the electromagnet 121 is in the open state, and the trigger spring 122 is in the compressed state. When the balance plate 2 is in the horizontal position, the electromagnet 121 is in the closed state. Under the action of the rebound force of the trigger spring 122, the fixing column 111 is inserted into the connecting groove 21 and abuts against the inner wall of the connecting groove 21, so that the fixing column 111 limits the balance plate 2.

[0046] Reference Figure 1 The hoisting mechanism 3 includes a first hoisting component 31 and a second hoisting component 32. The balance plate 2 has a first moving groove 22 and a second moving groove 23 along its own length on the side away from the hoisting plate 1. The first moving groove 22 and the second moving groove 23 are arranged opposite to each other. The first hoisting component 31 moves back and forth in the first moving groove 22 in the horizontal direction, and the second hoisting component 32 moves back and forth in the second moving groove 23 in the horizontal direction.

[0047] Both the first lifting assembly 31 and the second lifting assembly 32 include a lifting box 311 and a hanger 312. The hanger 312 is located on the side of the lifting box 311 away from the balance plate 2, and the steel frame 9 abuts against the hanger 312. The lifting box 311 corresponding to the first lifting assembly 31 is slidably connected to the inner wall of the first moving groove 22, and the lifting box 311 corresponding to the second lifting assembly 32 is slidably connected to the inner wall of the second moving groove 23. A first screw 221 is rotatably connected in the first moving groove 22, and a second screw 231 is rotatably connected in the second moving groove 23. The lifting box 311 corresponding to the first lifting assembly 31 is threadedly connected to the first screw 221, and the lifting box 311 corresponding to the second lifting assembly 32 is threadedly connected to the second screw 231. Each of the first screw 221 and the second screw 231 is connected to a motor 33, and the first screw 221 and the second screw 231 have opposite threaded sections.

[0048] Reference Figure 3 and Figure 4 To improve the limiting ability of the hanger 312 on the reinforcing steel cage 9, a limiting component 34 is provided on the hanger 312. The limiting component 34 includes a pulley 341 and a limiting plate 342. The hanger 312 has a buffer groove 35 and a limiting groove 36 in the vertical direction, which are arranged opposite to each other. A buffer column 351 is slidably connected in the buffer groove 35, and a buffer spring 352 is provided in the buffer groove 35. One end of the buffer spring 352 is fixed to the bottom of the buffer groove 35, and the other end is fixed to the buffer column 351. The pulley 341 is rotatably connected to the end of the buffer column 351 away from the buffer spring 352. The limiting plate 342 is slidably connected to the limiting groove 36, and an electric push rod 361 is fixed to the bottom of the limiting groove 36. The output end of the electric push rod 361 is fixed to the limiting plate 342. The limiting plate 342 and the pulley 341 respectively abut against both sides of the reinforcing steel cage 9.

[0049] When the reinforcing steel cage 9 needs to be hoisted, the operator uses a crane to hoist the lifting plate 1 and the balance plate 2 onto the reinforcing steel cage 9, so that the reinforcing steel cage 9 abuts against the pulley 341. The operator then activates the electric push rod 361, which controls the limit plate 342 to abut against the reinforcing steel cage 9. At this time, the crane starts and performs a trial hoisting action. The operator observes the detection value of the tilt sensor 112 to determine whether the balance plate 2 is in a horizontal state, the electromagnet 121 is in the open state and the trigger spring 122 is in the compressed state. When the balance plate 2 is not in a horizontal state, the electric push rod 361 controls the limit plate 342 to separate from the reinforcing steel cage 9. At this time, the motor 33 starts, and the motor 33 drives the corresponding first screw 221 and the corresponding second screw 231 to rotate, thereby adjusting the position of the two hoisting boxes 311, and thus adjusting the position between the hanger 312 and the reinforcing steel cage 9. At this time, the pressure received by the buffer column 351 is transmitted to the buffer spring 352. The buffer spring 352 absorbs and disperses part of the pressure, thus buffering the steel reinforcement cage 9 and preventing damage to the steel reinforcement cage 9 when the hanger 312 moves. After the position of the hanger 312 is adjusted, a trial lifting operation is performed and the test value of the tilt sensor 112 is observed. When the balance plate 2 is in a horizontal state, the electromagnet 121 is turned off. Under the action of the spring 122's rebound force, the fixing column 111 is inserted into the connecting groove 21 and abuts against the inner wall of the connecting groove 21 to complete the limiting of the balance plate 2, reducing the possibility of the balance plate 2 shifting during the subsequent transfer of the steel reinforcement cage 9.

[0050] Reference Figure 1 To improve the connection stability between the suspended platform 1 and the balance plate 2, a stabilizing assembly 4 is provided on the suspended platform 1. The stabilizing assembly 4 includes a stabilizing frame 41, a stabilizing cylinder 42, and a stabilizing rope 43. The stabilizing frame 41 is fixed to the suspended platform 1, the stabilizing cylinder 42 is rotatably connected to the stabilizing frame 41, and the stabilizing rope 43 is wound around the stabilizing cylinder 42. One end of the stabilizing rope 43 away from the stabilizing cylinder 42 passes through the suspended platform 1 and is fixed to the balance plate 2. A torsion spring 44 is wound around the rotating shaft of the stabilizing cylinder 42. One end of the torsion spring 44 is fixed to the stabilizing frame 41, and the other end is fixed to the stabilizing cylinder 42.

[0051] Reference Figure 5 and Figure 6To reduce the possibility of the stabilizing cylinder 42 rotating when the reinforcing steel frame 9 moves, a locking assembly 13 for locking the stabilizing cylinder 42 is provided on the hanging plate 1. The locking assembly 13 includes a locking frame 131, a locking plate 132, and a pull rope 133. The locking frame 131 is fixed on the hanging plate 1, and the locking plate 132 is slidably connected to the locking frame 131. A locking block 134 is provided at the end of the locking plate 132 away from the locking frame 131. A locking groove 421 that mates with the locking block 134 is provided on the rotating shaft of the stabilizing cylinder 42. A mating groove 14 that communicates with the fixing groove 11 is provided on the hanging plate 1 in the vertical direction. One end of the pull rope 133 is fixed to the locking plate 132, and the other end passes through the mating groove 14 and enters the fixing groove 11 and is fixed to the fixing column 111. Furthermore, the locking frame 131 is rotatably connected to the first roller 45 and the second roller 46, and the pull rope 133 is sequentially wound around the first roller 45 and the second roller 46.

[0052] During the trial lifting of the steel reinforcement cage 9, when the balance plate 2 shifts, it pulls the rope 133, causing the stabilizing cylinder 42 to rotate, and the torsion spring 44 to be compressed. After the position adjustment between the hanger 312 and the steel reinforcement cage 9 is completed, the balance plate 2 gradually becomes horizontal. At this time, under the action of the rebound force of the torsion spring 44, the stabilizing cylinder 42 retracts the rope 133. When the tilt sensor 112 detects that the balance plate 2 is horizontal, the electromagnet 121 is turned off, and under the action of the rebound force of the trigger spring 122, the fixing column 111 is inserted into the connecting groove 21. The fixing column 111 then pulls the rope 133, which in turn drives the second roller 46 and the first roller 45 to rotate. The end of the rope 133 away from the first roller 45 then drives the locking plate 132 and the locking block 134 to move towards the stabilizing cylinder 42. When the locking block 134 is engaged in the locking groove 421, the stabilizing cylinder 42 is locked, making it less likely for the stabilizing cylinder 42 to rotate when the steel reinforcement cage 9 is moved. This allows the pull rope 133 to connect the hanging plate 1 and the balance plate 2 more stably, reducing the possibility of the hanging plate 1 and the balance plate 2 separating. This improves the stability when moving the steel reinforcement cage 9 and also improves the accuracy of the operator when transferring the steel reinforcement cage 9.

[0053] Reference Figure 1 and Figure 7 In order to reduce the possibility of bending in the middle section of the steel reinforcement cage 9, an auxiliary box 5 is provided on the side of the balance plate 2 away from the hanging plate 1. An auxiliary groove 51 is provided in the auxiliary box 5. An auxiliary plate 52 is slidably connected in the vertical direction in the auxiliary groove 51. The side of the auxiliary plate 52 away from the balance plate 2 abuts against the steel reinforcement cage 9, and the auxiliary plate 52 is controlled by the auxiliary component 6.

[0054] The auxiliary component 6 includes a negative pressure plate 61, an auxiliary spring 62, a first connecting pipe 63, and a second connecting pipe 64. The negative pressure plate 61 and the hanger 312 are slidably connected in the lifting box 311, with the negative pressure plate 61 connected to the hanger 312. The auxiliary spring 62 is vertically positioned within the lifting box 311, with one end fixed to the inner wall of the lifting box 311 and the other end fixed to the negative pressure plate 61. One end of the first connecting pipe 63 is connected to the lifting box 311, and the other end is connected to the second connecting pipe 64. The end of the second connecting pipe 64 away from the first connecting pipe 63 is connected to the auxiliary groove 51.

[0055] Reference Figure 7 and Figure 8 A control plate 641 is slidably connected to the second connecting pipe 64, and an auxiliary gear 53 is rotatably connected to the auxiliary groove 51. The shaft of the auxiliary gear 53 is set in the horizontal direction. A first rack 642 is fixed on the control plate 641, and the first rack 642 meshes with the auxiliary gear 53. A second rack 521 is fixed along the length of the auxiliary plate 52, and the second rack 521 meshes with the auxiliary gear 53. At this time, a first negative pressure space 65 is formed between the negative pressure plate 61 and the control plate 641.

[0056] Reference Figure 7 and Figure 9 In order to improve the connection stability between the fixed column 111 and the balance plate 2, the end of the first connecting pipe 63 away from the hanging box is connected to the third connecting pipe 66, and the third connecting pipe 66 is connected to the second connecting pipe 64. The end of the third connecting pipe 66 away from the first connecting pipe 63 is connected to the auxiliary box 5.

[0057] The auxiliary box 5 has a reinforcing groove 54 communicating with the connecting groove 21, and the fixing post 111 extends into the reinforcing groove 54. The auxiliary box 5 has a stabilizing groove 55 communicating with the reinforcing groove 54 in a horizontal direction, and the stabilizing groove 55 is connected to the third connecting pipe 66. A reinforcing plate 661 is slidably connected in the third connecting pipe 66, and the reinforcing plate 661 extends into the stabilizing groove 55. A reinforcing hole 662 is formed on the reinforcing plate 661, and the fixing post 111 abuts against the inner wall of the reinforcing hole 662. The inner wall of the reinforcing hole 662 is provided with a reinforcing component 67 for limiting the fixing post 111. A second negative pressure space 68 is formed between the negative pressure plate 61 and the reinforcing plate 661.

[0058] Reference Figure 9The reinforcement component 67 includes a reinforcement column 671 and a reinforcement spring 672. The inner wall of the reinforcement hole 662 is provided with a first clearance groove 663. The reinforcement column 671 is slidably connected in the first clearance groove 663. The reinforcement spring 672 is disposed in the first clearance groove 663. One end of the reinforcement spring 672 is fixed to the reinforcement column 671 and the other end is fixed to the bottom of the first clearance groove 663. The fixing column 111 is provided with a second clearance groove 113 that cooperates with the reinforcement column 671. The reinforcement column 671 extends into the second clearance groove 113 and abuts against the inner wall of the second clearance groove 113.

[0059] Reference Figure 10 and Figure 11 In order to facilitate the control of the control board 641 and the reinforcement plate 661, a diverter plate 7 is rotatably connected at the connection between the first connecting pipe 63 and the second connecting pipe 64 and the third connecting pipe 66, and a connecting component 8 for controlling the diverter plate 7 is provided on the hanger 312.

[0060] The connecting assembly 8 includes a connecting plate 81, a telescopic plate 82, and a control rod 83. The connecting plate 81 is fixed horizontally to the hanger 312, and a telescopic groove 811 is formed along its length. The telescopic plate 82 is slidably connected in the telescopic groove 811. The control rod 83 is fixed vertically to the telescopic plate 82, and a control strip 831 is spirally provided on the control rod 83. The diverter plate 7 has a control hole 71 that mates with the control rod 83, and the inner wall of the control hole 71 has a spiral groove 72 that mates with the control strip 831. The telescopic plate 82 facilitates the movement of the connecting plate 81 and the control rod 83 as the lifting box 311 moves.

[0061] When the balance plate 2 is in a horizontal position, the operator can move the reinforcing cage 9, at which point the diversion plate 7 closes the second connecting pipe 64. During the raising of the hanger 312, under the weight of the hanger 312 and the reinforcing cage 9, the hanger 312 and the negative pressure plate 61 move away from the balance plate 2, and the auxiliary spring 62 is compressed. At this time, under the action of the second negative pressure space 68, the reinforcing plate 661 gradually retracts into the third connecting pipe 66. When the reinforcing hole 662 connects with the reinforcing groove 54, under the action of the rebound force of the trigger spring 122, the fixing column 111 plate is inserted into the reinforcing hole 662. When the fixed column 111 contacts the reinforcing column 671, the reinforcing column 671 is compressed and the reinforcing spring 672 is in a compressed state. When the second clearance groove 113 is opposite to the reinforcing column 671, under the action of the rebound force of the reinforcing spring 672, the reinforcing column 671 is inserted into the second clearance groove 113 to complete the reinforcement of the fixed column 111, thereby further improving the connection stability between the hanging plate 1 and the balance plate 2.

[0062] During the movement of the hanger 312, the hanger 312 drives the connecting plate 81, the telescopic plate 82, and the control rod 83 to move. Under the cooperation of the control bar 831 and the spiral groove 72, the control rod 83 gradually drives the diverter plate 7 to rotate toward the third connecting pipe 66. When the reinforcing plate 661 reinforces the fixed column 111, the diverter plate 7 rotates to close the third connecting pipe 66, making it difficult for the reinforcing plate 661 to continue moving under the action of the second negative pressure space 68, so that the reinforcing plate 661 can more stably limit the fixed column 111. At this time, the first connecting pipe 63 and the second connecting pipe 64 are connected. Under the action of the first negative pressure space 65, the control plate 641 gradually retracts into the second connecting pipe 64. The control plate 641 drives the first rack 642 to move. The first rack 642 drives the auxiliary gear 53 to rotate. The auxiliary gear 53 then drives the second rack 521 to move. The second rack 521 then drives the auxiliary plate 52 to move towards the steel reinforcement cage 9. When the auxiliary plate 52 abuts against the steel reinforcement cage 9, the auxiliary plate 52 supports the middle section of the steel reinforcement cage 9, making it less likely for the middle section of the steel reinforcement cage 9 to be bent. This further improves the stability when moving the steel reinforcement cage 9, and at the same time, it makes it easier for the crane to move the steel reinforcement cage 9 to the designated position more accurately.

[0063] The implementation principle of the precise hoisting device for a reinforcing steel cage according to this application embodiment is as follows: When it is necessary to transfer the reinforcing steel cage 9, the operator connects the reinforcing steel cage 9 to the hoisting mechanism 3, and then uses a crane to lift the balance plate 2 and the lifting plate 1 for a trial lift. The operator then observes the tilt degree of the balance plate 2 through the tilt sensor 112. When the balance plate 2 is in a horizontal state, the trigger component 12 controls the fixing column 111 to insert into the connecting groove 21. At this time, the fixing column 111 limits the balance plate 2, and at the same time, the stabilizing component 4 further strengthens the connection stability between the lifting plate 1 and the balance plate 2, improving the stability of the reinforcing steel cage 9 during movement, so that the crane can move the reinforcing steel cage 9 to the designated position more accurately.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
