Description

Technical Field

[0001] The present invention relates to the technical field related to hoisting devices, and in particular to a fully automatic hoisting device for a ship unloader. Background Art

[0002] The ship unloader, which consists of a bridge gantry and an automatic lifting device, is the main unloading equipment at the raw material terminal of a power plant. The automatic lifting device usually consists of a lifting device and a grab bucket. When unloading materials, the ship unloader adjusts the position of the grab bucket so that the grab bucket grabs the materials, and then places the materials on the transportation equipment through the gantry, realizing the unloading and transfer functions of the materials.

[0003] In situations where columnar materials such as wood, formed telephone poles and other designated materials are unloaded and transported, grab buckets are frequently used. The side of the material has an arc, and the grab bucket needs to maintain a stable grip on the material throughout the entire transportation process. Conventional grab buckets have two clamping claws driven by a hydraulic structure or a threaded drive structure. The energy consumption of the grab bucket is large when in use. When grabbing, the clamping claws act on the side of the material and are subjected to a large lateral force. Over time, the drive structure is easily damaged, and it is inconvenient to repair and replace the clamping claws. Summary of the Invention

The first top plate 101 is interlaced with the positioning rod 103 so that the arc grooves 105 on the first top plate 101 and the second top plate 102 will not stagger with each other, and the tops of the two movable rods 202 are respectively placed in the two arc grooves 105. The arc grooves 105 limit the rotation angle of the support rod 201, so that the support rod 201 can only rotate ninety degrees clockwise or counterclockwise. The top of the movable rod 202 is connected to the limiting plate 203, and the top of the first top plate 101 is connected to the top of the first top plate 101, and the ring 104 is connected to the external hoist.

[0029] Example 2

[0030] See Figure 1 、 2, 4, 5, 6, based on the embodiment 1, the clamping plate 4 includes a rotating plate 401, a rotating sleeve 403 connected to the side of the rotating plate 401 through a connecting rod 402, and a grabbing plate 404 detachably mounted on the end of the rotating plate 401. In this embodiment, the inner side wall of the grabbing plate 404 is provided with an adaptive arc surface 407, and the adaptive arc surface 407 acts on both sides of the lower part of the material 9. The bottom rod body of the rack rod 3 is ninety degrees, the rotating sleeve 403 is rotatably connected to the bottom of the rack rod 3, and the end of the support rod 201 supports the side wall of the rotating plate 401. In this embodiment, a docking groove 405 is provided on the side of the rotating plate 401, and the end of the support rod 201 can be inserted into the docking groove 405. The docking groove 405 has a planar groove inner end and an arc-shaped groove inner side wall. The setting of the docking groove 405 makes it difficult for the end of the support rod 201 to detach from the connection with the rotating plate 401 during support. When the support rod 201 rotates, its end moves along the arc-shaped groove inner side wall of the docking groove 405 until it contacts the planar groove inner end. A semi-cylindrical groove 406 is provided on the top of the rotating plate 401 to provide a movable space for the rotating shaft 204.

[0031] See also Figure 1 、 2 3. The bottom of the support rod 201 is detachably connected to a correction plate 206. The correction plate 206 is an arc-shaped plate that fits the top of the material 9. When the crane adjusts the position of the overall lifting device, the correction plate 206 can be in contact with the top of the material 9 to achieve rapid positioning of the lifting device. When grabbing different materials 9, the correction plate 206 corresponding to the shape of the material 9 can be replaced to cooperate with the work.

[0032] See also Figure 1 、 2, 8. A rope traction machine 10 is provided on the side of the bottom end of the second top plate 102, and a terminal block 408 is connected to the side of the rotating plate 401. The rope traction machine 10 is connected to the terminal block 408 through a traction rope 11. The rope traction machine 10 cooperates with the traction rope 11 to drive the end of the rotating plate 401 to move. The grabbing plate 404 and the rotating plate 401 are detachably connected to facilitate the inspection and replacement of the grabbing plate 404. The fixing can be strengthened by connecting a reinforcing plate 12 to the side of the rotating plate 401 and the grabbing plate 404. The top of the reinforcing plate 12 is connected and fixed to the top of the rotating plate 401 by bolts 13, and the bottom of the reinforcing plate 12 is connected and fixed to the rotating plate 401 and the grabbing plate 404 by bolts 13, so as to improve the connection stability of the rotating plate 401 and the grabbing plate 404 while improving the gripping effect. The service life of the taking plate 404, when the clamping plate 4 is not clamped, the two rotating plates 401 are in a state parallel to the ground, the two first top plates 101 are in contact with the second top plate 102, and the bottom of the limit plate 203 is in contact with the top of the first top plate 101. When the support assembly 2 is working, the traction rope 11 no longer pulls the rotating plate 401, and the support rod 201 moves up to drive the clamping plate 4 to rotate. The clamping plate 4 is in a vertical state with the ground under the action of gravity. At this time, the two grabbing plates 404 are clamped on both sides of the bottom of the material 9, and the support rod 201 moves and rotates ninety degrees to support the two rotating plates 401. At this time, the movable rod 202 moves up, and the pull ring is lifted by the crane to drive the first top plate 101 to move up to the bottom of the limit plate 203 and re-fit with the top of the first top plate 101, and it can be lifted and transported.

[0033] Working principle: When the lifting device is in use, the lifting ring 104 is connected to the external crane, and the entire device is adjusted to a position above the material 9 through the crane. The position of the device is adjusted so that the correction plate 206 is in contact with the top of the material 9 to position the entire device, so that the rope traction machine 10 releases the rope, and the telescopic member 6 is started to drive the rotating shaft 204 and the support rod 201 to move upward. The clamping plate 4 rotates under the action of its own gravity and the upward squeezing action of the support rod 201 until the side of the grabbing plate 404 is in contact with the bottom side of the material 9. When the support rod 201 moves to the height position corresponding to the docking groove 405, the driving member 803 is started to drive the disc gear 804 to rotate, and then the rotating shaft 204 is driven to rotate through the column gear 205, and then the support rod 201 is driven to rotate ninety degrees. The angle between the support rod 201 and the rotating plate 401 is ninety degrees. The lifting ring 104 is lifted by the crane, thereby driving the first top plate 101 to move upward, and then the first top plate 101 drives the limit plate 203 to move, and then the support rod 201 is driven to move by the movable rod 202, and the support rod 201 drives the rotating plate 401 and the grabbing plate 404 to move, and then cooperates with the crane to realize the lifting and transportation function. The driving member 803 only needs to bear the force used to maintain the relative angle between the support rod 201 and the rotating plate 401, and does not need to bear the gravity force from the material 9, so that during the entire grabbing and transportation process, no additional energy is required to maintain the stable clamping effect of the grabbing plate 404 on the material.

[0034] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
