Description

Technical Field

[0001] This invention belongs to the technical field of material lifting devices, and particularly relates to a follow-up lifting and guiding positioning type lifting device. Background Technology

[0002] A patent titled "A Column Load Lifting Device" (application number CN202510179251.9) is disclosed in the existing Chinese patent database. This device includes a base plate, a hydraulic component fixedly connected to the top right side of the base plate, a control rod rotatably connected to the top of the hydraulic component, a first roller rotatably connected to the bottom of the hydraulic component, and two linkage rods fixedly connected to the bottom of the hydraulic component. A component box is located at the top of each linkage rod, and a second roller rotatably connects to the right side of each linkage rod. Evenly distributed slide rails are fixedly connected to the top right side of the base plate. In this invention, by setting a hydraulic component at the bottom of the base plate, the linkage rods are moved under hydraulic control, causing the linkage rods to open the second rollers, thus raising the base plate. Simultaneously, the lifting column is adjusted according to the required load height, allowing the pod on top of the mounting plate to reach the installation position. This solves the problem of needing multiple adjustments when installing components at different heights.

[0003] When lifting and placing cylindrical goods into containers, the goods are prone to bumping and damage inside the containers, and the loading process is slow. In order to achieve rapid loading of goods into containers, this solution aims to propose a follow-up lifting and guiding positioning lifting device, which enables cylindrical goods to be loaded into containers quickly and stably, thereby improving loading efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to design a lifting device that enables columnar goods to be packed quickly and stably. In order to improve its shortcomings, the present invention provides a follow-up lifting and guiding positioning lifting device.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: A follow-up lifting and guiding positioning lifting device includes four columns. A crossbeam is provided between the upper parts of two horizontal columns, and a movable support is provided between two vertical columns. The movable support includes a main frame body slidably connected to the side of the columns. The upper surface of the main frame body is provided with an arc-shaped concave surface. A fixed support is provided on the outer side of the two vertical columns. The upper surface of the fixed support is provided with a concave surface of the same diameter as the movable support.

[0006] As a preferred embodiment, a fixed sleeve is connected to the inner side of the movable bracket, and a pin is connected inside the fixed sleeve. A synchronously rotating connecting plate is sleeved on the pin facing away from the crossbeam. A U-shaped clamping plate is provided on the inner side of the movable bracket, and the free end of the connecting plate is located inside the clamping plate. A limit pin hole is opened on the crossbeam directly opposite the pin.

[0007] As a preferred embodiment, a guide box is connected to the inner side of the movable bracket, and a connecting rod is inserted inside the guide box. Two limiting nuts are screwed onto one end of the connecting rod, and the connecting plate is sleeved on the connecting rod between the two limiting nuts. The clamping plate is provided on the inner side of the movable bracket located at the connecting plate, and the free end of the connecting plate is located inside the clamping plate. The other end of the connecting rod is connected to a pin, and the limiting pin hole is opened on the transverse side directly opposite the pin.

[0008] As a preferred embodiment, a clamping device is provided on the side of the column. The clamping device includes a sleeve fixed to the side of the column, a lifting rod vertically connected inside the sleeve, a horizontal clamping frame rotatably connected to the upper section of the lifting rod, a limit rod horizontally slidably connected inside the clamping frame, a limit head integrally provided at the free end of the limit rod, a limit seat provided on the side of the column, and a limit hole provided on the limit seat. When the clamping frame is pressed down, the limit head is inserted into the limit hole.

[0009] As a preferred embodiment, a vertical guide strip is integrally provided on the side of the movable support facing the column. The column is hollow inside and has a vertical guide tube. A compression spring is sleeved on the guide tube. A square tube support is gapped on the upper guide tube. The upper inner surface of the square tube support abuts against the upper surface of the compression spring. A vertical strip groove is opened on the surface of the square tube support facing the movable support. The guide strip is inserted into the corresponding strip groove.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Due to the sliding connection of the movable support on the column, when the goods are put into the box, the column goods can be placed on the concave surface of the movable support along the lateral direction of the two movable supports. Then the lifting equipment slowly descends and uses the weight of the column goods to press the movable support down to be flush with the fixed support. At this time, the compression spring inside the column is in a compressed state, which can also play a certain role in shock absorption during transportation. 2. The clamping device is designed so that after the cylindrical cargo is clamped, rotating the clamping frame will cause the clamping frame to come into contact with the upper surface of the cylindrical cargo, ensuring the stability of the cylindrical cargo during transportation. 3. When no goods are placed on the movable support, it is locked between the pin and the crossbeam to prevent it from shaking due to its own weight, thus improving safety during use; 4. When lifting goods from the container, the return function of the compression spring exerts an upward thrust on the movable support, which facilitates lifting and helps to align the lifting equipment, preventing the columnar goods from shifting. This device is suitable for industrial production and has strong practicality. Attached Figure Description

[0016] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-5As shown, a follow-up lifting and guiding positioning lifting device includes four columns 1. A crossbeam 2 is arranged between the upper parts of two horizontal columns 1, and a movable support 3 is arranged between two vertical columns 1. The movable support 3 includes a main frame body slidably connected to the side of the columns 1. The upper surface of the main frame body is provided with an arc-shaped concave surface 4. A fixed support 5 is arranged on the outer side of the two vertical columns 1. The upper surface of the fixed support 5 is provided with a concave surface 4 of the same diameter as the movable support 3. A fixed sleeve 6 is connected to the inner side of the movable support 3. A pin 7 is connected inside the fixed sleeve 6. A synchronously rotating connecting plate 8 is sleeved on the pin 7 on the side opposite to the crossbeam 2. A U-shaped clamping plate 9 is arranged inside the movable support 3. The free end of the connecting plate 8 is located inside the clamping plate 9. A limit pin hole 10 is opened on the crossbeam 2 directly opposite the pin 7. The inner side of the movable bracket 3 is connected to a guide box 11, and a connecting rod 12 is inserted inside the guide box 11. One end of the connecting rod 12 is screwed with two limiting nuts 13. A connecting plate 8 is sleeved on the connecting rod 12 between the two limiting nuts 13. A clamping plate 9 is provided on the inner side of the movable bracket 3 located at the connecting plate 8. The free end of the connecting plate 8 is located inside the clamping plate 9. The other end of the connecting rod 12 is connected to a pin 7. A limiting pin hole 10 is opened on the transverse side directly opposite the pin 7. A clamping device 14 is provided on the side of the column 1. The clamping device 14 includes a sleeve 15 fixed to the side of the column 1. A lifting rod 16 is vertically connected inside the sleeve 15. A horizontal clamping frame 17 is rotatably connected to the upper section of the lifting rod 16. A limit rod 18 is horizontally slidably connected inside the clamping frame 17. A limit head 19 is integrally provided at the free end of the limit rod 18. A limit seat 20 is provided on the side of the column 1. A limit hole 21 is opened on the limit seat 20. When the clamping frame 17 is pressed down, the limit head 19 is inserted into the limit hole 21. A vertical guide strip 22 is integrally provided on the side of the movable support 3 facing the column 1. The inside of the column 1 is hollow and is provided with a vertical guide tube 23. A compression spring 24 is sleeved on the guide tube 23. A square tube support 25 is sleeved on the upper guide tube 23 with a gap. The upper inner surface of the square tube support 25 abuts against the upper end surface of the compression spring 24. A vertical strip groove 26 is opened on the surface of the square tube support 25 facing the movable support 3. The guide strip 22 is inserted into the strip groove 26.

[0018] The implementation process of this invention is as follows: The device is placed inside the box. When it is necessary to pack cylindrical goods, the pin 7 that limits the movable support 3 and the crossbeam 2 is removed. The cylindrical goods are placed on the concave surface 4 of the two movable supports 3 using the lifting equipment. The lifting device is slowly lowered so that the weight of the cylindrical goods presses down on the movable supports 3, causing them to descend until the movable supports 3 and the fixed support 5 are on the same horizontal plane. The lifting device is then released, and the clamping frame 17 in the clamping device 14 is rotated to be above the cylindrical goods, pressing only on the surface of the cylindrical goods. At the same time, the limiting head 19 at the free end of the limiting rod 18 is inserted. The columnar goods are placed into the limiting hole 21 to complete the packing process. During the packing process, the movable bracket 3 plays a buffering role in assisting the hoisting of the goods and preventing damage caused by collisions between the goods and the box. During transportation, the compression spring 24 can play a certain role in shock absorption. When the goods are unpacked, the clamping frame 17 in the clamping device 14 is rotated and moved to one side. The columnar goods are slowly lifted with the help of the crane bracket. After the movable bracket 3 returns to its original position, the pin 7 is inserted into the pin hole and the movable bracket 3 is fixed to the crossbeam 2 again.
