Description

Technical Field

[0001] This utility model relates to the field of hoisting mechanism technology, and in particular to a hoisting device for helium gas tube bundles. Background Technology

[0002] Helium has unique chemical and physical properties and is widely used in industry, medicine, scientific research and other fields. When transporting helium, cylinders containing helium are usually placed in containers, and the containers are lifted by a hoisting mechanism to realize the transfer, filling and releasing of helium.

[0003] There are various container lifting devices in the existing technology. For example, Chinese patent CN212450281U discloses a container assembly lifting and fixing device, including a first mounting plate and a second mounting plate. A hanging ring is fixedly installed at the center of the upper end of the first mounting plate, and a top plate is slidably installed inside the hanging ring. A tightening screw is rotatably connected to the lower end of the top plate. A double-acting screw is rotatably installed on the right end face of the second mounting plate. Nut blocks are threadedly installed at intervals on the body of the double-acting screw. Hollow clamp rods are fixedly installed at the lower end of each nut block. Support screw rods are rotatably installed inside each hollow clamp rod. A base plate is fixedly installed at the lower end of each support screw rod. This device can realize container lifting operations. However, the adjustment of the hollow rod position and the locking of the double-acting screw in the above device need to be done manually. During the lifting operation, the position of the lifting seat is generally high, and users are prone to danger when working at height, making it inconvenient to use.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0023] See Figures 1-5This utility model provides a hoisting device for helium gas container bundles, comprising:

[0024] The hoisting base 1 has several movable pulleys 11 rotatably mounted on its top end. Each movable pulley 11 is rotatably connected to a movable pulley seat. Each movable pulley 11 is connected to at least two hoisting cables 12. The hoisting cables 12 are connected to the overhead crane base. The overhead crane base provides tension to the hoisting base 1 through the several hoisting cables 12, thereby driving the hoisting base 1 to rise and fall. At the same time, the overhead crane base can also drive the hoisting base 1 to move horizontally. The structure and principle of the overhead crane base are common knowledge to those skilled in the art, so they will not be described in detail in this utility model.

[0025] Four cable shafts 2 are located below the lifting base 1. Each cable shaft 2 is fixedly connected to a positioning seat, and each positioning seat is fixedly connected to the bottom surface of the lifting base 1. Each cable shaft 2 is fixedly connected to a hook cable 21. Each hook cable 21 is fixedly connected to a hook 22 at the end away from the cable shaft 2. The hook 22 is connected to the lifting ring on the container mechanism, which enables the lifting base 1 to drive the container mechanism to lift and move.

[0026] Furthermore, users can place the lifting rings on the container mechanism at the four corners of the bottom of the container mechanism, thereby avoiding workers working at heights and improving the safety of the device.

[0027] Two movable seats 3 are slidably connected to the lifting seat 1. The two movable seats 3 are symmetrically arranged with respect to the center of the lifting seat 1. Each end of the movable seat 3 is provided with a fixed pulley 33. The fixed pulley 33 is rotatably connected to the fixed pulley seat 32. The fixed pulley seat 32 is fixedly connected to the bottom surface of the movable seat 3. The fixed pulley 33 corresponds one-to-one with the hook cable 21. The hook cable 21 passes through the fixed pulley 33. The fixed pulley 33 can change the direction of the hook cable 21, thereby changing the position of the hook 22.

[0028] A threaded shaft 5 is located below the lifting base 1, parallel to the movement direction of the moving base 3. Both ends of the threaded shaft 5 are rotatably connected to end plates, which are fixedly connected to the bottom surface of the lifting base 1. A driving component (not shown in the figure) is fixedly connected to one of the end plates. The output shaft of the driving component is connected to the threaded shaft 5 via a coupling, and the driving component can drive the threaded shaft 5 to reciprocate. The threaded shaft 5 has two threaded seats 51, which are symmetrically arranged with respect to the center of the threaded shaft 5. The surface of the threaded shaft 5 has two threads in opposite directions, and the two threads correspond one-to-one with the two threaded seats 51. When the threaded shaft 5 rotates, it can drive the two threaded seats 51 to move closer or further away synchronously. A fixed plate 31 is fixedly connected to the bottom surface of the movable seat 3. The threaded shaft 5 passes through the fixed plate 31. Several limiting rods 53 are fixedly connected to the side wall of the threaded seat 51 near the fixed plate 31. The limiting rods 53 all pass through the fixed plate 31 close to them. A limiting plate is fixedly connected to the end of the limiting rod 53 away from the threaded seat 51. A spring is sleeved on the outside of the limiting rod 53. The two ends of the spring are fixedly connected to the threaded seat 51 and the fixed plate 31 respectively. More specifically, the spring is a compression spring. Several vertical through slots are opened on the movable seat 3. A mounting seat 4 is fixedly connected to the bottom surface of the movable seat 3 at the through slot. A movable magnet 41 is fixedly connected to the mounting seat 4. The movable magnet 41 is located in the through slot. Several sets of fixed magnets 13 are fixedly connected to the bottom surface of the hoisting seat 1. The fixed magnets 13 and the movable magnets 41 can attract each other. When the fixed magnets 13 and the movable magnets 41 abut and attract each other, the movable seat 3 can be limited.

[0029] Two positioning plates 6 correspond one-to-one with the movable seat 3. The positioning plates 6 are both located below the movable seat 3 and are slidably connected to the movable seat 3. Several positioning pins 61 are fixedly connected to the top surface of the positioning plates 6. The movable seat 3 has pin holes corresponding to the positioning pins 61. The positioning pins 61 are always located in the pin holes. Several positioning holes 14 corresponding to the positioning pins 61 are opened on the bottom surface of the hoisting seat 1. A connecting rod 52 is rotatably connected between adjacent positioning plates 6 and threaded seat 51. That is, one end of the connecting rod 52 is rotatably connected to the positioning plate 6, and the other end of the connecting rod 52 is rotatably connected to the threaded seat 51.

[0030] See Figures 1-5 Preferably, a bending plate 7 is fixedly connected to both ends of the top surface of the movable seat 3. The top of the bending plate 7 bends towards the hoisting seat 1. A guide wheel 71 is rotatably connected to the top of the bending plate 7. A guide rail 15 corresponding to the guide wheel 71 is fixedly connected to the top surface of the hoisting seat 1.

[0031] See Figures 1-5 Preferably, both the fixed magnet 13 and the movable magnet 41 are permanent magnets.

[0032] See Figures 1-5Preferably, the cable shaft 2 can also be rotatably connected to the fixed seat through a structure such as a bushing or bushing. Each fixed seat is equipped with an adjustment motor, and the output shaft of the adjustment motor is connected to the cable shaft 2 through a coupling. The adjustment motor can drive the cable shaft 2 to rotate and self-lock when it stops running. By adjusting the motor, the extension length of the cable shaft 2 can be adjusted to avoid tilting during the hoisting operation.

[0033] See Figures 1-5 Preferably, the driving component is a rotary motor, which can provide sufficient power.

[0034] See Figures 1-5 Preferably, the movable pulley 11 and the movable pulley seat, the fixed pulley 33 and the fixed pulley seat 32, the threaded shaft 5 and the end plate, and the bent part 7 and the guide wheel 71 can all be connected by bearings, bushings and other structures. The connecting rod 52 and the positioning plate 6, and the connecting rod 52 and the threaded seat 51 can all be connected by pins, hinges and other structures.

[0035] See Figures 1-5 As another embodiment of the present invention, at least six hook cables 21 are fixedly connected to the bottom surface of the lifting base 1, and hooks 22 are fixedly connected to the bottom end of each hook cable 21. With the six hooks 22, when the device is only used for lifting container mechanisms of two length specifications, the lifting operation requirements of the above-mentioned container mechanism can be met by the six hooks 22.

[0036] In the implementation of this utility model: When this device needs to lift a long container, the drive unit is activated, which drives the threaded shaft 5 to rotate clockwise, causing the two threaded seats 51 to move away from each other. In the initial state, the threaded seats 51 are located on the side of the positioning plate 6 away from the fixed plate 31, the spring is in its natural state, and the positioning pin 61 does not engage with the positioning hole 14. At this time, the threaded seats 51 move away from the center of the threaded shaft 5. Since the moving magnet 41 abuts against and attracts one of the fixed magnets 13, the moving seat 3 does not move initially. The spring is gradually compressed, and the positioning plate 6 rises. When the positioning plate 6 and the threaded seats 51 are on the same vertical plane, i.e., the connecting rod 52... When in the vertical position, the positioning pin 61 is located in the positioning hole 14. The threaded seat 51 continues to move away from the center of the threaded shaft 5 until the threaded seat 51 abuts against the fixed plate 31 (or the spring is compressed to its limit). At this time, the threaded seat 51 can push the moving seat 3 to move. The moving magnet 41 disengages from the fixed magnet 13, and the moving seat 3 moves away from the lifting seat 1 until the moving magnet 41 abuts against another set of fixed magnets 13 and attracts each other. At this time, the threaded shaft 5 reverses, causing the threaded seat 51 to move closer to the center of the threaded shaft 5 until the connecting rod 52 rotates back to the vertical position. The positioning pin 61 engages with the positioning hole 14 to achieve the positioning of the moving seat 3.

[0037] When this device needs to lift a shorter container, the drive unit drives the threaded shaft 5 to reverse, causing the two threaded seats 51 to move closer to each other. When the spring is in its natural state, the limit block abuts against the side wall of the fixed plate 31, and the threaded seat 51 can drive the movable seat 3 to move towards the center of the lifting seat 1.

[0038] This utility model provides a hoisting device for helium gas cartridge bundles, which has the following advantages:

[0039] 1. By setting up structures such as a movable seat, threaded shaft, and threaded seat, the position of the hook can be adjusted to make the device suitable for lifting operations of container mechanisms of different lengths, thus expanding the applicability of the device. It can also automatically position the movable seat to avoid danger caused by accidental movement of the movable seat during lifting operations.

[0040] 2. In this utility model, the position adjustment of the hook and the locking of the movable seat can be automatically completed by the reciprocating motion of the threaded seat, which reduces the number of drive mechanisms used. Long-term use can reduce the cost of use to a certain extent and meet the needs of enterprises to reduce costs and increase efficiency.

[0041] In summary, the beneficial effects of this utility model are: it can automatically adjust the position of the hook to meet the hoisting operations of container mechanisms of different lengths and specifications, and it can also self-lock the position of the hook to prevent it from moving during use, thereby improving the safety of the device.

[0042] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
