[0040] Reference Figures 1-6 For the first embodiment of the present application, a spherical tank hoisting sling is proposed for hoisting a spherical tank 1, the spherical tank 1 has a material inlet 101 at the top and a material outlet 102 at the bottom, the material inlet 101 has a pipe flange 103, comprising a circular arc guard plate 2, the circular arc guard plate 2 is sleeved on the pipe flange 103, and one side abuts against the spherical tank 1; a plurality of support columns 3 are arranged on the circular arc guard plate 2; a mounting plate 4 is arranged on the other end of the plurality of support columns 3, and the mounting plate 4 abuts against and is bolted to the pipe flange 103; a plurality of hook-shaped lifting lugs 5 are arranged on the circular arc guard plate 2, and a hoisting rope is wound on the hook-shaped lifting lug 5.

[0041] In this embodiment, in order to solve the problem that the spherical tank device for use has no suitable lifting appliance for lifting when being moved, a spherical tank lifting appliance is designed. First, a circular arc guard plate 2 is made, which can be accurately sleeved on the pipe flange 103 and tightly abut against the spherical tank 1 on one side. Then, a number of (such as 4) support columns 3 are prepared, which are firmly welded on the circular arc guard plate 2 at one end to ensure the stability and strength of the connection. Then, the mounting plate 4 is arranged at the other end of the support columns 3, so that the mounting plate 4 tightly abuts against the pipe flange 103 and is connected by using a suitable size of bolt to ensure the integrity of the whole structure. Finally, the lifting rope is wound on the hook-shaped lifting lug 5, and the lifting operation of the spherical tank 1 is prepared.

[0042] The advantage is that the circular arc guard plate 2 is sleeved on the pipe flange 103 and abuts against the spherical tank 1, the support columns 3 connect the circular arc guard plate 2 and the mounting plate 4, and the hook-shaped lifting lug 5 cooperates with the lifting rope, which can effectively connect the lifting appliance with the spherical tank 1, provides a reliable force point for the lifting of the spherical tank 1, solves the problem of no suitable lifting appliance for the spherical tank 1 when being moved, and the structure is relatively simple and easy to manufacture and install.

[0043] Further, the support columns 3 are circumferentially distributed along the axis of the circular arc guard plate 2.

[0044] In this embodiment, a number of (assuming 4) support columns 3 are circumferentially distributed along the axis of the circular arc guard plate 2. The advantage is that the design of the support columns 3 circumferentially distributed along the axis of the circular arc guard plate 2 makes the lifting appliance bear the weight of the spherical tank 1 more evenly, avoids damage to the lifting appliance or instability such as inclination of the spherical tank 1 during lifting due to excessive local stress, improves the safety and reliability of lifting, and further ensures the smooth progress of the moving operation of the spherical tank 1.

[0045] Further, the mounting plate 4 coincides with the axis of the circular arc guard plate 2, and further comprises a lifting appliance mounting boom 6, one end of which is arranged on the mounting plate 4 and coincides with the axis of the mounting plate 4, and the other end is connected with the lifting rope. After the mounting plate 4 abuts against the pipe flange 103, the other end of the lifting appliance mounting boom 6 is located inside the spherical tank 1.

[0046] In this embodiment, the mounting plate 4 is made coinciding with the axis of the arc-shaped guard plate 2. A hanger mounting hoist 6 is prepared, one end of which is fixed vertically at the center of the mounting plate 4 by welding. When using external lifting equipment for hanger installation, the hook of the crane is connected with the hanger mounting hoist 6 of the hanger, the position is adjusted to align the arc-shaped guard plate 2 with the pipe flange 103 at the bottom of the spherical tank 1, the hanger mounting hoist 6 is slowly lifted to a suitable height, and the arc-shaped guard plate 2 can be smoothly sleeved into the bottom of the spherical tank 1 and closely fitted with the wall of the spherical tank 1. At this time, the mounting plate 4 is accurately butted with the pipe flange 103, ensuring that the hanger is firmly and reliably connected with the spherical tank 1.

[0047] The advantage is that the mounting plate 4 coincides with the axis of the arc-shaped guard plate 2 and the structure design of the hanger mounting hoist 6, which can accurately position the hanger during installation, and the hanger can be conveniently and quickly connected with the bottom of the spherical tank 1 with the help of external lifting equipment, improving the installation efficiency and accuracy.

[0048] Further, it also includes a sliding ring 7 which is slidingly arranged on the hanger mounting hoist 6; a plurality of first connecting rods 8, one end of each first connecting rod 8 being hingedly arranged on the mounting plate 4; a plurality of second connecting rods 9, one end of each second connecting rod 9 being hingedly arranged on the other end of each first connecting rod 8, and the other end of each second connecting rod 9 being hingedly arranged on the sliding ring 7. When the sliding ring 7 slides close to the mounting plate 4, the side walls of the plurality of first connecting rods 8 are in abutment with the edges of the material outlet 102.

[0049] In this embodiment, the sliding ring 7 is installed on the hanger mounting hoist 6, which can smoothly slide on the hanger mounting hoist 6. A plurality of (e.g. 6) first connecting rods 8 are prepared, one end of each first connecting rod 8 being arranged on the mounting plate 4 by hinged connection. One end of each second connecting rod 9 is hingedly arranged on the other end of each first connecting rod 8, and the other end of each second connecting rod 9 is hingedly arranged on the sliding ring 7. When the sliding ring 7 slides close to the mounting plate 4, the side walls of the 6 first connecting rods 8 can be in close abutment with the edges of the material outlet 102, and can accurately contact the edges of the material outlet 102 and provide stable support force.

[0050] The advantage is that the combination of the sliding ring 7, the first connecting rod 8 and the second connecting rod 9 allows the first connecting rod 8 to abut with the edges of the material outlet 102 when the sliding ring 7 slides close to the mounting plate 4, thereby playing a role of auxiliary support and positioning for the bottom of the spherical tank 1 during hoisting, effectively preventing the spherical tank 1 from shaking or deviating due to its own gravity or external factors, improving the stability of the hoisting of the spherical tank 1, and ensuring the safety and efficiency of the displacement operation of the spherical tank 1.

[0051] Furthermore, the sling mounting boom 6 has a cavity 601, the mounting plate 4 has a plurality of through holes 401, and also includes a rope connector 10, one end of the rope connector 10 is slidably set in the cavity 601, located inside the spherical tank 1, and the other end is used to connect the mounting rope; one end of the traction rope 11 is connected to the slip ring 7, and the traction rope 11 passes through the through hole 401 into the cavity 601 and is connected to the rope connector 10; the rope connector 10 slides away from the mounting plate 4, so that the slip ring 7 slides close to the mounting plate 4.

[0052] In this embodiment, one end of the rope connector 10 is able to slide in the cavity 601 of the sling mounting boom 6. The other end of the rope connector 10 is processed into a structure suitable for connecting the mounting rope. Then, a traction rope 11 is prepared, and one end of it is firmly connected to the slip ring 7. The traction rope 11 passes through the through hole 401 of the mounting plate 4 into the cavity 601 of the sling mounting boom 6, and is then connected to the rope connector 10. During operation, by pulling the rope connector 10 to slide it away from the mounting plate 4 in the cavity 601, due to the connecting action of the traction rope 11, the slip ring 7 will correspondingly slide closer to the mounting plate 4, thereby realizing the abutment action between the first connecting rod 8 and the edge of the material outlet 102.

[0053] Furthermore, it also includes an elastic member 12, which is sleeved on the sling mounting rod 6, and the two ends of the elastic member 12 act on the sling mounting rod 6 and the slip ring 7 respectively, for providing a force to keep the slip ring 7 away from the mounting plate 4.

[0054] In this embodiment, the setting of the elastic member 12 provides the slip ring 7 with an initial force away from the mounting plate 4, so that when there is no external traction, the first connecting rod 8 will not expand, avoiding unnecessary collision or friction between the first connecting rod 8 and the material outlet 102 due to misoperation or other factors. When the rope connector 10 is pulled externally, the elastic force provided by the elastic member 12 is greater than the gravity of the sling itself, so that the slip ring 7 will not slide. When the sling is installed, the rope connector 10 is continuously provided with a pulling force by installing the rope, thereby overcoming the elastic force of the elastic member 12, so that the first connecting rod 8 will contact the material outlet 102, so that the side walls of the six first connecting rods 8 can all be tightly abutted against the edge of the material outlet 102, and can accurately contact the edge of the material outlet 102 and provide stable support force. At the same time, during the hoisting process, the elastic force of the elastic member 12 can also play a certain buffering role, improving the safety and reliability of the sling, and facilitating the smooth shifting and hoisting of the spherical tank 1.

[0055] Furthermore, the first connecting rod 8 and the second connecting rod 9 are evenly distributed along the circumference of the axis of the sling mounting boom 6 .

[0056] In the embodiment, the first connecting rod 8 and the second connecting rod 9 are evenly distributed along the axis of the hoist mounting hoist 6, so that when the connecting rod mechanism is used to assist in supporting and positioning the bottom of the spherical tank 1, the support force in each direction is evenly distributed, avoiding deformation of the bottom of the spherical tank 1 or damage to the hoist due to uneven local stress, further improving the stability and safety of the hoisting of the spherical tank 1, and ensuring the smooth operation of the spherical tank 1 shifting operation.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
