Description

Technical Field

[0001] This application relates to the field of transfer arms, and in particular to a lifting structure for a transfer robotic arm. Background Technology

[0002] A transfer arm, also known as a transfer rail, is typically used in conjunction with a shelf or platform for moving items. The shelf or platform moves with the support of the transfer arm, and it is a device that assists in moving items. It is usually used to move some heavy items and can greatly reduce the workload of moving items.

[0003] When a transfer arm is used in a factory, it will generally carry heavy objects. To facilitate the installation and use of the transfer arm, I-beams are fixed to the top of the factory to support the transfer arm and make it easier for the transfer arm to carry heavy objects and move them within the factory.

[0004] The existing method of fixing the load-bearing arm generally involves using clips to connect the extended side of the I-beam and then fixing the clips to the load-bearing arm. Under high-load conditions, simply using clips to fix the I-beam to the load-bearing arm is a weak fixing method, which is prone to shaking and difficult to maintain stability. Summary of the Invention

[0005] The purpose of this application is to address the problem that existing fixed load-bearing arms, as mentioned in the background art, generally use clips to connect the extended side of the I-beam and then fix the clips to the load-bearing arm. Under high-load conditions, simply using clips to fix the I-beam and the transfer arm together is a weak fixing method that is prone to swaying and difficult to maintain stability. This application provides a hoisting structure for a transfer robotic arm.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A hoisting structure for a transfer robotic arm includes an I-beam, on which a transfer arm is mounted. A connecting channel steel is provided between the I-beam and the transfer arm. A connecting channel steel is fixed to the first connecting channel steel, and a connecting channel steel is fixed to the second connecting channel steel. The groove of the third connecting channel steel corresponds to the transfer arm. The third connecting channel steel and the grooves on both sides of the transfer arm are fixedly connected by bolts. Two symmetrical fixing plates are provided on the first connecting channel steel. Fixing bolts are provided between the fixing plates and the first connecting channel steel. The fixing plates and the first connecting channel steel are fixedly connected by fixing bolts. A pad rod is fixed to one side of the fixing plate. A fixing mechanism is provided on one side of the first connecting channel steel, and a reinforcing mechanism is provided on the fixing mechanism.

[0007] By adopting the above technical solution, when installing the transfer arm on the I-beam, the widened fixing plate is used to fix the I-beam and the connecting channel steel one together, and the connecting channel steel three is used to fix the two sides of the transfer arm. At the same time, the fixing mechanism is squeezed by the I-beam, which further clamps and limits the I-beam. Then, the reinforcement mechanism also further fixes the transfer arm, so that the transfer arm can be stably installed on the I-beam, improving the stability of the transfer arm. With the assistance of the fixing mechanism and the reinforcement mechanism, the connection between the connecting channel steel one and the I-beam and the connection between the transfer arm and the connecting channel steel three can be further improved, further improving the stability of the transfer arm.

[0008] Furthermore, the fixing mechanism includes a connecting plate fixed on a connecting channel steel, two symmetrical support plates fixed on the connecting plate, a bearing plate disposed between the two support plates, a clamping plate disposed on each of the two support plates, a clamping assembly disposed between the clamping plate and the bearing plate, and a limit assembly disposed on the bearing plate.

[0009] By adopting the above technical solution, during the approach process, the I-beam is positioned between the two support plates of the connecting plate, allowing the I-beam to press against the bearing plate. The bearing plate then drives the clamping assembly, which in turn drives the corresponding clamping plate to clamp and fix the I-beam. When the two clamping plates completely clamp the I-beam, the limiting assembly restricts the bearing plate, thereby further improving the connection strength between the I-beam and the connecting channel steel and enhancing the stability of the transfer arm.

[0010] Furthermore, the clamping assembly includes sliding blocks disposed on both sides of the support plate, the sliding blocks being fixedly connected to the support plate, a sliding groove being formed on the support plate, the sliding blocks corresponding to the sliding groove, the sliding blocks being slidably connected to the support plate, a connecting rod being rotatably connected to the sliding blocks, a pressing block being rotatably connected to the end of the connecting rod away from the sliding blocks, the pressing block penetrating the support plate and being slidably connected to the support plate, and the end of the pressing block away from the connecting rod being fixedly connected to the clamping plate.

[0011] By adopting the above technical solution, the bearing plate drives the sliding block to slide on the support plate, and then the sliding block drives the connecting rod, the connecting rod drives the pressing block, and the pressing block drives the clamping plate to move closer to the I-beam under the restriction of the support plate. This allows the two clamping plates to restrict the I-beam and make the I-beam as close as possible to the middle of the connecting channel steel, which facilitates the insertion of fixing bolts.

[0012] Furthermore, the limiting component includes a limiting rod slidably connected to the support plate. The limiting rod passes through the support plate and is slidably connected to the support plate. One end of the limiting rod facing the bearing plate has an upward inclined surface. A limiting spring is provided between the limiting rod and the support plate. Both ends of the limiting spring are fixedly connected to the limiting rod and the support plate.

[0013] By adopting the above technical solution, when the bearing plate moves to the position of the limiting rod, the bearing plate presses against the inclined surface of the limiting rod, allowing the limiting rod to slide on the support plate. When the bearing plate moves below the limiting rod, the limiting rod resets under the action of the limiting spring. This makes the clamping plate more stable when clamping the I-beam and reduces the possibility of the clamping plate loosening its grip on the I-beam.

[0014] Furthermore, an arc-shaped plate is fixed on the clamping plate, with the convex surface of the arc-shaped plate facing the I-beam.

[0015] By adopting the above technical solution, when the I-beam is about to enter between the two clamping plates, the side of the I-beam abuts against the curved surface of the curved plate, thus making it easier for the I-beam to enter between the two clamping plates.

[0016] Furthermore, a support spring is provided between the bearing plate and the connecting plate, and both ends of the support spring are fixedly connected to the support plate and the connecting plate.

[0017] By adopting the above technical solution, the bearing plate is in a lifted state under the support of the supporting spring, and the bearing plate drives the clamping plate to remain open, so that the I-beam can be more easily inserted between the two clamping plates.

[0018] Furthermore, the reinforcement mechanism includes a downward pressure rod disposed on the connecting plate, the downward pressure rod passing through the connecting plate and slidably connected to the connecting plate, one end of the downward pressure rod being fixedly connected to the bearing plate, and two symmetrical reinforcement rods disposed at the end of the downward pressure rod away from the bearing plate, with reinforcement blocks fixed on the reinforcement rods, the reinforcement blocks corresponding to the grooves on the transfer arm, and a driving assembly disposed between the downward pressure rod and the reinforcement rods.

[0019] By adopting the above technical solution, the bearing plate presses down the pressure rod, and the pressure rod presses down the drive component. Under the action of the drive component, the two reinforcing rods move closer to each other, and the reinforcing blocks on the reinforcing rods enter the grooves on the transfer arm, thereby further fixing the transfer arm and improving the stability of the connection between the transfer arm and the connecting channel steel.

[0020] Furthermore, the driving assembly includes a driving block one fixed to the end of the lower pressure rod away from the bearing plate. The driving block one is in the shape of an isosceles triangle. Driving blocks two are slidably connected to the inclined surfaces on both sides of the driving block one. The driving blocks two are in the shape of a right triangle. The isosceles inclined surface of the driving block one abuts against the inclined surface of the inclined side of the driving block two. A connecting block is fixed on the driving block two. A slide rail is fixed on the connecting channel steel two. The connecting block and the slide rail are slidably connected.

[0021] By adopting the above technical solution, the first drive block moves downward, allowing the two second drive blocks to approach each other under the constraints of the slide rail and the first drive block. This allows the two fixed blocks to simultaneously restrict the transfer arm, thereby further reducing the offset of the transfer arm and improving the stability between the transfer arm and the connecting channel steel.

[0022] In summary, this application includes at least one of the following beneficial effects; 1. In this application, when the transfer arm is installed on the I-beam, a widened fixing plate is used to fix the I-beam and the connecting channel steel one together. The connecting channel steel three wraps and fixes both sides of the transfer arm. At the same time, the I-beam squeezes the bearing plate, and the bearing plate drives the sliding block to slide on the support plate, allowing the connecting rod to drive the squeezing block. Under the restriction of the support plate, the squeezing block drives the clamping plate to move closer to the I-beam, and the clamping plate clamps and limits the I-beam. At the same time, the bearing plate squeezes the pressure rod, and the pressure rod squeezes the driving component. Under the action of the driving component, the two reinforcing rods move closer to each other, allowing the reinforcing blocks on the reinforcing rods to enter the grooves on the transfer arm, further restricting the transfer arm. This achieves the goal of enabling the transfer arm to be stably installed on the I-beam, improving the stability of the transfer arm. At the same time, the action of the fixing block and the clamping plate further improves the connection between the connecting channel steel one and the I-beam and further improves the connection between the transfer arm and the connecting channel steel three, further improving the stability of the transfer arm.

[0023] 2. In this application, when the bearing plate presses down the pressure rod, the pressure rod presses down the drive block one, and the drive block moves down, so that the two drive blocks two are brought closer to each other under the restriction of the slide rail and the drive block one. This allows the fixing block on the fixing rod to enter the groove on the transfer arm, so that the two fixing blocks can clamp the bearing arm at the same time, thereby further reducing the offset of the transfer arm and improving the stability between the transfer arm and the connecting channel steel three.

[0024] 3. In this application, when the I-beam is not in contact with the bearing plate, the bearing plate is in a lifted state under the support of the supporting spring, and the bearing plate drives the clamping plate to remain open. This makes it easier for the I-beam to enter between the two clamping plates and reduces the possibility of the clamping plate obstructing the I-beam. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0028] This application discloses a hoisting structure for a transfer robotic arm.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A hoisting structure for a transfer arm 2 includes an I-beam 1, on which a transfer arm 2 is mounted. A connecting channel steel 3 is provided between the I-beam 1 and the transfer arm 2. A connecting channel steel 4 is fixed to the connecting channel steel 3, and a connecting channel steel 5 is fixed to the connecting channel steel 4. The groove of the connecting channel steel 5 corresponds to the transfer arm 2. The connecting channel steel 3 and the grooves on both sides of the transfer arm 2 are fixedly connected by bolts. Two symmetrical fixing plates 8 are provided on the connecting channel steel 3. Fixing bolts 9 are provided between the fixing plates 8 and the connecting channel steel 3. The fixing plates 8 and the connecting channel steel 3 are fixedly connected by fixing bolts 9. A pad rod 10 is fixed to one side of the fixing plate 8. A fixing mechanism 6 is provided on one side of the connecting channel steel 3. A reinforcing mechanism 7 is provided on the fixing mechanism 6.

[0030] When the hoisting structure is needed, firstly, use bolts to fix the connecting channel steel 3 5 and the transfer arm 2 together, so that the connecting channel steel 3 5 restricts the two sides of the transfer arm 2. Then, move the transfer arm 2 to the position of the I-beam 1, so that the connecting channel steel 3 abuts against the bottom of the I-beam 1. Then, use the widened fixing plate 8 to abut against the protruding side of the I-beam 1. Then, use fixing bolts 9 to pass through the fixing plate 8 and the connecting channel steel 3, and use the fixing bolts 9 to clamp and fix the fixing plate 8 and the connecting channel steel 3 against the side of the I-beam 1. When fixing the fixing plate 8, the pad rod 10 supports the fixing plate 8 to keep the fixing plate 8 horizontal. When the connecting channel steel 3 is brought close to the bottom of the I-beam 1, the I-beam 1 squeezes the fixing mechanism 6. Under the compression of the I-beam 1, the fixing mechanism 6 clamps the two sides of the I-beam 1 and limits the I-beam 1, so that the I-beam 1 is located in the middle of the connecting channel steel 3. When the I-beam 1 presses against the fixing mechanism 6, the fixing mechanism 6 drives the reinforcing mechanism 7, which further clamps the transfer arm 2. By using the widened fixing plate 8 to fix the I-beam 1 and the connecting channel steel 3 together when the transfer arm 2 is installed on the I-beam 1, and using the connecting channel steel 3 5 to fix the two sides of the transfer arm 2, the fixing mechanism 6 is further clamped and limited by the pressure of the I-beam 1. Then, the reinforcing mechanism 7 also further fixes the transfer arm 2, so that the transfer arm 2 can be stably installed on the I-beam 1, improving the stability of the transfer arm 2. At the same time, with the assistance of the fixing mechanism 6 and the reinforcing mechanism 7, the connection between the connecting channel steel 3 and the I-beam 1 and the connection between the transfer arm 2 and the connecting channel steel 3 5 can be further improved, further improving the stability of the transfer arm 2.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The fixing mechanism 6 includes a connecting plate 66 fixed on the connecting channel steel 3. Two symmetrical support plates 61 are fixed on the connecting plate 66. A bearing plate 62 is provided between the two support plates 61. A clamping plate 63 is provided on each of the two support plates 61. A clamping assembly 64 is provided between the clamping plate 63 and the bearing plate 62. A limit assembly 65 is provided on the bearing plate 62.

[0032] After the connecting channel steel 3 5 is fixed together with the transfer arm 2, the transfer arm 2 moves the connecting channel steel 1 3, connecting channel steel 2 4, and connecting channel steel 3 5 closer to the I-beam 1. During the approach, the I-beam 1 is positioned between the two support plates 61 of the connecting plate 66, causing the I-beam 1 to press against the bearing plate 62. The bearing plate 62 then moves the clamping assembly 64, which in turn moves the corresponding clamping plate 63 to clamp and fix the I-beam 1. When the two clamping plates 63 completely clamp the I-beam 1, the limiting assembly 65 restricts the bearing plate 62, preventing it from resetting. By moving the connecting channel steel 1 3 closer to the I-beam 1 and fixing it with the fixing plate 8, the I-beam 1 presses against the bearing plate 62, causing the bearing plate 62 to move the two symmetrical clamping plates 63 to clamp and limit the I-beam 1. This further improves the connection strength between the I-beam 1 and the connecting channel steel 1 3, and enhances the stability of the transfer arm 2.

[0033] Reference Figure 2 and Figure 4 The clamping assembly 64 includes sliding blocks 641 disposed on both sides of the support plate 62. The sliding blocks 641 are fixedly connected to the support plate 62. A sliding groove 642 is provided on the support plate 61. The sliding blocks 641 correspond to the sliding groove 642. The sliding blocks 641 are slidably connected to the support plate 61. A connecting rod 643 is rotatably connected to the sliding block 641. A pressing block 644 is rotatably connected to the end of the connecting rod 643 away from the sliding block 641. The pressing block 644 passes through the support plate 61 and is slidably connected to the support plate 61. The end of the pressing block 644 away from the connecting rod 643 is fixedly connected to the clamping plate 63.

[0034] When the connecting channel steel 3 is brought closer to the I-beam 1, the I-beam 1 presses against the bearing plate 62 between the two support plates 61. The bearing plate 62 drives the sliding block 641 to slide on the support plate 61. Then the sliding block 641 drives the connecting rod 643, and the connecting rod 643 drives the pressing block 644. Under the restriction of the support plate 61, the pressing block 644 drives the clamping plate 63 to move closer to the I-beam 1, and uses the clamping plate 63 to clamp and limit the I-beam 1. By making the I-beam 1 press against the bearing plate 62 and simultaneously drive the two sliding blocks 641, the two clamping plates 63 can restrict the I-beam 1, so that the I-beam 1 is located as close as possible to the middle of the connecting channel steel 3, which facilitates the insertion of the fixing bolt 9.

[0035] Reference Figure 2 and Figure 4The limiting component 65 includes a limiting rod 651 slidably connected to the support plate 61. The limiting rod 651 passes through the support plate 61 and is slidably connected to the support plate 61. The end of the limiting rod 651 facing the bearing plate 62 has an upward inclined surface. A limiting spring 652 is provided between the limiting rod 651 and the support plate 61. Both ends of the limiting spring 652 are fixedly connected to the limiting rod 651 and the support plate 61. When the I-beam 1 presses against the bearing plate 62, the bearing plate 62 moves under the pressure of the support plate 61. When the bearing plate 62 moves to the position of the limiting rod 651, the bearing plate 62 presses against the inclined surface of the limiting rod 651, allowing the limiting rod 651 to slide on the support plate 61. When the bearing plate 62 moves below the limiting rod 651, the limiting rod 651 resets under the action of the limiting spring 652, causing the limiting rod 651 to abut against the bearing plate 62. By using the limiting rod 651 to restrict the bearing plate 62, the clamping plate 63 can be made more stable when clamping the I-beam 1, reducing the possibility of the clamping plate 63 loosening its grip on the I-beam 1.

[0036] Reference Figure 2 and Figure 3 An arc-shaped plate 11 is fixed on the clamping plate 63, with the protruding surface of the arc-shaped plate 11 facing the I-beam 1.

[0037] As the I-beam 1 is about to enter between the two clamping plates 63, the side of the I-beam 1 abuts against the arc surface of the arc plate 11. Under the constraint of the arc plate 11, the relative positions of the I-beam 1 and the clamping plates 63 are roughly corresponding. By utilizing the constraint of the arc plate 11, the I-beam 1 can enter between the two clamping plates 63 more easily.

[0038] Reference Figure 1 and Figure 3 A support spring 12 is provided between the support plate 62 and the connecting plate 66. Both ends of the support spring 12 are fixedly connected to the support plate 61 and the connecting plate 66.

[0039] When the I-beam 1 is not in contact with the bearing plate 62, the bearing plate 62 is in a lifted state under the support of the support spring 12, and the bearing plate 62 drives the clamping plate 63 to remain open. By using the support spring 12 to support the bearing plate 62, the two clamping plates 63 are kept open, so that the I-beam 1 can enter between the two clamping plates 63 more easily.

[0040] Reference Figure 1 , Figure 3 and Figure 5The reinforcement mechanism 7 includes a downward pressure rod 73 disposed on the connecting plate 66. The downward pressure rod 73 passes through the connecting plate 66 and is slidably connected to the connecting plate 66. One end of the downward pressure rod 73 is fixedly connected to the bearing plate 62. Two symmetrical reinforcement rods 71 ​​are disposed at the end of the downward pressure rod 73 away from the bearing plate 62. Reinforcing blocks 72 are fixed on the reinforcement rods 71. The reinforcement blocks 72 correspond to the grooves on the transfer arm 2. A driving assembly 74 is disposed between the downward pressure rod 73 and the reinforcement rods 71.

[0041] When the I-beam 1 presses against the bearing plate 62, the bearing plate 62 presses against the lower pressure rod 73, and the lower pressure rod 73 presses against the driving component 74. Under the action of the driving component 74, the two reinforcing rods 71 ​​move closer to each other, allowing the reinforcing blocks 72 on the reinforcing rods 71 ​​to enter the grooves on the transfer arm 2, further restricting the transfer arm 2. By pressing against the bearing plate 62 while the I-beam 1 presses against the bearing plate, allowing the reinforcing blocks 72 on the reinforcing rods 71 ​​to enter the grooves on the transfer arm 2, the transfer arm 2 can be further fixed, improving the stability of the connection between the transfer arm 2 and the connecting channel steel 3 5.

[0042] Reference Figure 1 and Figure 5 The drive assembly 74 includes a drive block 741 fixed to the end of the lower pressure rod 73 away from the bearing plate 62. The drive block 741 is in the shape of an isosceles triangle. Drive blocks 742 are slidably connected to the inclined surfaces on both sides of the drive block 741. Drive blocks 742 are in the shape of a right triangle. The isosceles inclined surface of the drive block 741 abuts against the inclined surface of the inclined side of the drive block 742. A connecting block 744 is fixed on the drive block 742. A slide rail 743 is fixed on the connecting channel steel 2 4. The connecting block 744 and the slide rail 743 are slidably connected.

[0043] When the bearing plate 62 presses down the pressure rod 73, the pressure rod 73 presses down the drive block 741, causing the drive block 741 to move downward. This allows the two drive blocks 742 to approach each other under the constraint of the slide rail 743 and the drive block 741, allowing the fixing block on the fixing rod to enter the groove on the transfer arm 2. By having the drive block 741 simultaneously drive the two drive blocks 742, the two fixing blocks simultaneously restrict the transfer arm 2, thereby further reducing the offset of the transfer arm 2 and improving the stability between the transfer arm 2 and the connecting channel steel 3 5.

[0044] Working principle: When this hoisting structure is needed, firstly, the connecting channel steel 35 and the transfer arm 2 are fixed together with bolts, so that the connecting channel steel 35 restricts both sides of the transfer arm 2. Then, the transfer arm 2 is moved to the position of the I-beam 1. During the approach, the I-beam 1 is positioned between the two support plates 61 of the connecting plate 66, so that the I-beam 1 presses against the bearing plate 62. The bearing plate 62 drives the sliding block 641 to slide on the support plate 61. Then, the sliding block 641 drives the connecting rod 643, and the connecting rod 643 drives the pressing block 644, pressing... Block 644, under the constraint of support plate 61, moves clamping plate 63 closer to I-beam 1 and clamps and limits I-beam 1. When bearing plate 62 moves to the position of limiting rod 651, bearing plate 62 presses the inclined surface of limiting rod 651, allowing limiting rod 651 to slide on support plate 61. When bearing plate 62 moves below limiting rod 651, limiting rod 651 resets under the action of limiting spring 652, limiting bearing plate 62 and making the two clamping plates 63 tightly abut against I-beam 1.

[0045] While the I-beam 1 is pressing against the bearing plate 62, the bearing plate 62 is pressing against the lower pressure rod 73. The lower pressure rod 73 is pressing against the first driving block 741, causing the first driving block 741 to move downward. This allows the two second driving blocks 742 to approach each other under the constraint of the slide rail 743 and the first driving block 741, allowing the fixing block on the fixing rod to enter the groove on the transfer arm 2. This further restricts the transfer arm 2, completing the connection between the transfer arm 2 and the I-beam 1. Then, the widened fixing plate 8 is used to abut against the protruding side of the I-beam 1. Then, the fixing bolt 9 passes through the fixing plate 8 and the connecting channel steel 3, using the fixing bolt 9 to clamp and fix the side of the I-beam 1 with the fixing plate 8 and the connecting channel steel 3. When fixing the fixing plate 8, the pad rod 10 supports the fixing plate 8, keeping the fixing plate 8 horizontal, thus completing the connection between the bearing arm and the I-beam 1.
