[0037] For the convenience of understanding the technical solution of the present invention, the following is a detailed description in combination with the attached drawings and specific embodiments.

[0038] Embodiment 1

[0039] As Figures 1-12 shown, a double-arm lifting device for spraying a storage dome includes a tower body slewing lifting platform 1, a crane 2, a nested tower body 3, a tower body jacking system 4, a foundation chassis 5, and a single-jib gin pole 6;

[0040] The foundation chassis 5 is arranged on the ground and is the load-bearing component of the entire lifting device;

[0041] The nested tower body 3 is arranged on the foundation chassis 5 and is formed by nesting several tower body standard sections, that is, the sizes of several tower body standard sections increase in sequence, and the tower body standard section with a large size is sleeved outside the tower body standard section with a small size;

[0042] The tower body jacking system 4 is connected between the foundation chassis 5 and the nested tower body 3 and is used to jack up the tower body standard section of the nested tower body 3;

[0043] The tower body slewing and lifting platform 1 is rotationally fitted on the nested tower body 3, and includes a slewing and lifting assembly 11 and slewing platforms 12 located on both sides of the slewing and lifting assembly 11. Among them, the slewing and lifting assembly 11 has a slewing function and a lifting function. When slewing, it can drive the slewing platform 12 to rotate and spray the wall surface of the storage dome. When lifting, it can drive the slewing platform 12 to make fine adjustments in height to adapt to the arc change of the wall surface of the storage dome;

[0044] The crane 2 is arranged on the slewing platform 12;

[0045] Specifically, two cranes 2 are arranged on the surface of the tower body slewing and lifting platform 1. The crane 2 can move on the slewing platform 12 and can lift heavy objects on the ground to the adjustable platform 14 at the same time;

[0046] The single-boom gin pole 6 is arranged on the tower body slewing and lifting platform 1 and can lift goods.

[0047] Specifically, the present invention provides a double-arm lifting device for spraying the storage dome. A rotatable tower body slewing and lifting platform 1 is arranged on the liftable nested tower body 3, and slewing platforms 12 are arranged on both sides of the tower body slewing and lifting platform 1 to realize multi-directional spraying operations, greatly improving the construction efficiency.

[0048] Specifically, the nested tower body 3 includes 5 tower body standard sections, namely the first tower body standard section 31, the second tower body standard section 32, the third tower body standard section 33, the fourth tower body standard section 34, and the fifth tower body standard section 35, and their sizes decrease in sequence; the bottom of the fifth tower body standard section 35 is connected to the foundation chassis 5, that is, the second tower body standard section 32 is sleeved outside the first tower body standard section 31, the third tower body standard section 33 is sleeved outside the second tower body standard section 32, the fourth tower body standard section 34 is sleeved outside the third tower body standard section 33, and the fifth tower body standard section 35 is sleeved outside the fourth tower body standard section 34.

[0049] As Figure 11 shown, the tower body jacking system 4 includes a first multi-stage oil cylinder 41 and a second multi-stage oil cylinder 42. The two ends of the first multi-stage oil cylinder 41 are respectively connected to the foundation chassis 5 and the first tower body standard section 31, and the two ends of the second multi-stage oil cylinder 42 are respectively connected to the fifth tower body standard section 35 and the third tower body standard section 33. The movement of the first multi-stage oil cylinder 41 and the second multi-stage oil cylinder 42 causes the five tower body standard sections to be jacked up.

[0050] The first multi-stage oil cylinder 41 and the second multi-stage oil cylinder 42 are arranged in a staggered manner inside the tower body standard section to prevent interference.

[0051] The first tower body standard section 31 and the third tower body standard section 33 are both provided with connecting ear plates, and the driving ends of the first multi-stage oil cylinder 41 and the second multi-stage oil cylinder 42 are respectively connected to the connecting ear plates.

[0052] like Figures 6-7 , Figure 12 As shown, in this embodiment, the lifting process includes the following steps:

[0053] S100: The first multi-stage oil cylinder 41 is used to lift the first tower body standard section 31 located at the outermost layer. When the first tower body standard section 31 is fully extended, the lower end of the first tower body standard section 31 is connected and fixed to the adjacent second tower body standard section 32 through a connecting pin, so that the first tower body standard section 31 and the second tower body standard section 32 form a whole.

[0054] S200: Continue to extend the first multi-stage oil cylinder 41 to lift the first tower body standard section 31 and the second tower body standard section 32 together. When the second tower body standard section 32 is fully extended, the lower end of the second tower body standard section 32 is connected and fixed to the adjacent third tower body standard section 33 through a connecting pin, so that the first tower body standard section 31, the second tower body standard section 32 and the third tower body standard section 33 form a whole.

[0055] S300: retract the first multi-stage oil cylinder 41, and lift the third tower body standard section 33 by the second multi-stage oil cylinder 42. When the third tower body standard section 33 is fully extended, the lower end of the third tower body standard section 33 is connected and fixed to the adjacent fourth tower body standard section 34 by a connecting pin, so that the first tower body standard section 31, the second tower body standard section 32, the third tower body standard section 33 and the fourth tower body standard section 34 form a whole.

[0056] S400: Continue to extend the second multi-stage oil cylinder 42 to lift the fourth tower body standard section 34. When the fourth tower body standard section 34 is fully extended, the lower end of the fourth tower body standard section 34 is connected and fixed to the adjacent fifth tower body standard section 35 through a connecting pin. At this point, all tower body standard sections complete the lifting process, and finally retract the second multi-stage oil cylinder 42.

[0057] The retracting of the first multi-stage oil cylinder 41 in S300 may be accomplished by manually releasing the pin connection at the connection between the first multi-stage oil cylinder 41 and the first tower body standard section 31, or by using an existing pushing mechanism to push the pin out; in general, for those skilled in the art, releasing the connection between the first multi-stage oil cylinder 41 and the first tower body standard section 31 is an existing technology and will not be described in detail.

[0058] like Figures 1-3As shown in the figure, in this embodiment, the main body of the tower body slewing and lifting platform 1 further includes an electric hoist 13 and an adjustable platform 14. The electric hoist 13 is movably fitted on the slewing platform 12, and the adjustable platform 14 is slidably fitted at the end of the slewing platform 12. The adjustable platform 14 is connected to the slewing platform 12 by a lead screw and can move about 1 m under the action of the lead screw, realizing stepless adjustment of spraying within a radial range of 1 m on the inner wall of the storage dome.

[0059] The electric hoist 13 is installed on the lower track of the slewing platform 12 and moves back and forth on the track, enabling the lifting of heavy objects.

[0060] As Figure 5 shown in the figure, specifically, the slewing and lifting assembly 11 is composed of an upper support 111, a slewing bearing 112, an oil cylinder 113, and a lower support 114. The lower end of the oil cylinder 113 is connected to the lower support 114, and the upper end of the oil cylinder 113 is connected to the end of the nested tower body 3. The upper end of the lower support 114 is rotatably fitted with a slewing bearing 112, and an upper support 111 is provided on the slewing bearing 112. The slewing platform 12 is connected to the upper support 111.

[0061] When the oil cylinder 113 extends downward, it can drive the lower support 114 to move downward for fine adjustment of the height of the slewing platform 12, realizing stepless adjustment within the vertical range and covering the working surface of the storage side wall in a small vertical range. By the rotation of the slewing bearing 112, the upper support 111 is driven to rotate, and then the slewing platform 12 is driven to rotate. Specifically, the slewing bearing 112 can be used for manual slewing or motor slewing, and two-way rotation limit switches are set. When the switch acts, the rotation angle of the boom does not exceed ±120°, covering the working surface of the storage side wall in the horizontal direction.

[0062] The slewing platform 12 is designed to be detachable, and the slewing platform 12 can be disassembled or replaced, facilitating the control of the length of the slewing platform 12. Railings are provided on both sides of the slewing platform 12 to meet the walking requirements and safety protection requirements of the operators.

[0063] As Figure 4 shown in the figure, the slewing platform 12 is at least a double-layer platform structure. The adjacent platform structures are connected and fixed by diagonal bars 124. Each layer of the platform structure includes two parallel cross bars 121 and a number of longitudinal bars 122 located between the two parallel cross bars 121. The adjacent longitudinal bars 122 are connected by L-shaped bars 123. The two end points of the L-shaped bar 123 are connected to one longitudinal bar 122, and the inflection point of the L-shaped bar 123 is connected to another longitudinal bar 122.

[0064] As Figure 10As shown, the single-jib gin pole 6 includes a hook 61, a jib 62, a gin pole oil cylinder 63, a tower top 64, an upper support 65, a lower support 66, and a standard section 67; the standard section 67 is arranged on the side of the upper support 111, the lower support 66 is arranged on the standard section 67, the upper support 65 is rotationally matched with the lower support 66, the tower top 64 is located on the upper support 65, the jib 62 is hinged to the tower top 64, the gin pole oil cylinder 63 is connected between the jib 62 and the tower top 64, and the hook 61 is located on the jib 62.

[0065] The cross-section of the jib 62 is designed as a rectangle. The gin pole can control the luffing of the single-side jib 62 through the telescoping of the gin pole oil cylinder 63, and then lift the object to be lifted within the lifting range. Its hoisting, luffing, and slewing adopt frequency conversion control, and have protection functions such as overvoltage protection, undervoltage protection, open-phase protection, short-circuit overload protection, etc.

[0066] As Figure 9 As shown, the foundation chassis 5 includes a concrete foundation 51 and a chassis 52, and the chassis 52 is fixed to the concrete foundation 51 through embedded bolts 53.

[0067] The above is only the preferred implementation manner of the present invention. The protection scope of the present invention is subject to the scope defined by the claims.
