Description

Technical Field

[0001] This utility model belongs to the field of crane technology, specifically relating to a double-hook intelligent gantry crane. Background Technology

[0002] The two sets of hooks in a double-hook intelligent gantry crane are fixed in position. While the distance between the two sets of hooks can be adjusted to lift objects of varying lengths, this makes it difficult for the crane to handle objects of different lengths, significantly reducing the adjustability and applicability of the device. For example, Chinese utility model patent application CN115465790A discloses a double-hook intelligent gantry crane, but its two hooks cannot be raised and lowered independently, making it difficult to meet the requirements for independent lifting.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN118877730B discloses a double-hook intelligent gantry crane, in which although the two hooks can be lifted and lowered independently, the two lifting components cannot move independently on the crossbeam, making it difficult to meet the use requirements for independent lifting.

[0004] Therefore, it is necessary to design a double-hook intelligent gantry crane that can not only operate synchronously in parallel, but also operate independently to meet different lifting needs, in order to solve the current technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a double-hook intelligent gantry crane that can not only operate synchronously in parallel but also operate independently to meet different lifting needs.

[0006] The technical solution of this utility model is as follows: a double-hook intelligent gantry crane, including a crossbeam, on which a first trolley and a second trolley are arranged. Connecting bolts and spacing adjustment mechanisms are arranged on both sides of the first trolley. The spacing adjustment mechanism drives the connecting bolts to move along the direction of movement of the first trolley. Clamping locking mechanisms are arranged on both sides of the second trolley. The clamping locking mechanisms are used to clamp or release the connecting bolts. The clamping locking mechanism has a stop fixedly arranged on the outside of the second trolley. A support plate is fixedly arranged on the side of the stop away from the second trolley. Two clamping blocks are connected to the support plate. A clamping groove matching the connecting bolt is opened on the side of the two clamping blocks that are close to each other. A driving component is arranged on the support plate to drive the two clamping blocks to move closer or further apart.

[0007] Furthermore, two parallel connecting rods are hinged to the side of the clamping block near the support plate, and one end of the connecting rod opposite to the clamping block is hinged to the support plate; the driving assembly has a driving block, a driving rod is hinged to the driving block, and one end of the driving rod opposite to the driving block is hinged to the connecting rod; a hydraulic cylinder for driving the driving block to reciprocate is provided on the support plate.

[0008] Furthermore, the spacing adjustment mechanism has a rear support and a front support fixedly disposed on the side of the first trolley. A lead screw is rotatably disposed between the rear support and the front support. A servo motor for driving the lead screw to rotate is disposed on the rear support. A drive block is threadedly connected to the lead screw. Slide rods are fixedly disposed at both ends of the drive block. The slide rods are slidably connected to the front support. A support block is fixedly disposed at one end of the slide rod opposite to the drive block. The connecting bolt is fixedly disposed on one side of the support block.

[0009] Furthermore, a limit switch corresponding to the support block is provided on the side of the baffle near the connecting bolt.

[0010] Furthermore, a stop is fixedly provided on the end of the connecting bolt that is away from the support block.

[0011] The beneficial effects of this utility model are:

[0012] (1) In this utility model, the two sides of the second trolley are clamped or released between the clamping locking mechanism and the connecting bolts on both sides of the first trolley, which can connect the first trolley and the second trolley and run them in parallel and synchronously, or make the first trolley and the second trolley run independently to meet different lifting requirements.

[0013] (2) The clamp locking mechanism drives the two clamp blocks through the drive component. The clamp is fixed on the outside of the connecting bolt. The connecting bolt is not easy to come out between the two clamp blocks, thus ensuring the stability of the first trolley and the second trolley running side by side.

[0014] (3) The spacing adjustment mechanism can drive the connecting bolt to move relative to the first trolley, thereby adjusting the distance between the first trolley and the second trolley during parallel operation, realizing the adjustment of the lifting point spacing, and further meeting different lifting needs.

[0020] like Figures 1 to 3As shown, the double-hook intelligent gantry crane includes a crossbeam 1, on which a first trolley 2 and a second trolley 3 are mounted. Connecting bolts 5 and spacing adjustment mechanisms 4 are mounted on both sides of the first trolley 2. The spacing adjustment mechanisms 4 drive the connecting bolts 5 to move along the direction of movement of the first trolley 2. Clamping locking mechanisms 6 are mounted on both sides of the second trolley 3, used to clamp or release the connecting bolts 5. The clamping locking mechanism 6 has a stop 67 fixedly mounted on the outside of the second trolley 3. A support plate 67 is fixedly mounted on the side of the stop 67 facing away from the second trolley 3. Two clamping blocks 61 are connected to the support plate 67. Each clamping block 61 has a clamping groove 62 matching the connecting bolt 5 on its adjacent side. A drive assembly is mounted on the support plate 67 to drive the two clamping blocks 61 to move closer or further apart. In this embodiment, the two sides of the second trolley 3 are clamped or released between the clamping locking mechanism 6 and the connecting bolts 5 on both sides of the first trolley 2, which can connect the first trolley 2 and the second trolley 3 for parallel synchronous operation, or allow the first trolley 2 and the second trolley 3 to operate independently to meet different lifting requirements. The clamping locking mechanism 6 drives two clamping blocks 61 through a drive component, and the clamps are fixed to the outside of the connecting bolts 5. The connecting bolts 5 are not easy to come out between the two clamping blocks 61, ensuring the stability of the first trolley 2 and the second trolley 3 running side by side. The spacing adjustment mechanism 4 can drive the connecting bolts 5 to move relative to the first trolley 2, thereby adjusting the distance between the first trolley 2 and the second trolley 3 during parallel operation, realizing the adjustment of the lifting point spacing, and further meeting different lifting requirements.

[0021] In some embodiments, such as Figure 2 As shown, two parallel connecting rods 63 are hinged to the side of the clamping block 61 near the support plate 67. The end of the connecting rod 63 facing away from the clamping block 61 is hinged to the support plate 67. The drive assembly has a drive block 65, and a drive rod 64 is hinged to the drive block 65. The end of the drive rod 64 facing away from the drive block 65 is hinged to the connecting rod 63. A hydraulic cylinder 66 is provided on the support plate 67 to drive the drive block 65 to move back and forth. The hydraulic cylinder 66 drives the drive block 65 to move back and forth. The drive block 65 pushes and pulls the connecting rod 63 through the drive rod 64. The connecting rod 63 drives the clamping block 61 at one end to move back and forth. The two clamping blocks 61 cooperate to clamp or release the connecting bolt 5.

[0022] In some embodiments, such as Figure 3As shown, the spacing adjustment mechanism 4 has a rear support 41 and a front support 42 fixedly mounted on the side of the first trolley 2. A lead screw 43 is rotatably mounted between the rear support 41 and the front support 42. A servo motor 44 is mounted on the rear support 41 to drive the lead screw 43 to rotate. A drive block 45 is threadedly connected to the lead screw 43. Slide rods 46 are fixedly mounted at both ends of the drive block 45. The slide rods 46 are slidably connected to the front support 42. A support block 47 is fixedly mounted on the end of the slide rod 46 away from the drive block 45. A connecting bolt 5 is fixedly mounted on one side of the support block 47. The servo motor 44 drives the lead screw 43 to rotate. The threaded structure between the lead screw 43 and the drive block 45 can drive the drive block 45 to move along the axial direction of the lead screw 43. The drive block 45 drives the support block 47 to move through the slide rod 46. The support block 47 drives the connecting bolt 5 on one side of it to move synchronously, thereby realizing the movement of the connecting bolt 5 relative to the first trolley 2.

[0023] In some embodiments, a limit switch corresponding to the support block 47 is provided on the side of the stop 67 near the connecting bolt 5; when the support block 45 abuts against the stop 67, the limit switch is triggered. After the limit switch is triggered, the clamp locking mechanism 6 is controlled to clamp and fix the connecting bolt 5.

[0024] In some embodiments, a stop 51 is fixedly provided at one end of the connecting bolt 5 away from the support block 47. The stop 51 limits the clamping block 61 at the end of the connecting bolt 5, thereby improving the stability of the connection between the clamping locking mechanism 6 and the connecting bolt 5.
