Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] At present, when the wind ring is hoisted, it is generally installed with lifting ears, that is, the lifting ears are first welded to the wind ring, and then hoisted, and then the lifting ears are ground off after the hoisting is completed. This installation method is easy to cause welding burns to the wind ring, and the hoisting efficiency is also extremely low, which seriously affects the construction progress.

[0045] In view of this, the utility model provides a storage tank windproof ring lifting device, including a grab clamp fixed block 1, a grab clamp movable block 2, a limit pin 3 and a locking assembly 4; the grab clamp fixed block 1 is penetrated by the grab clamp movable block 2, and has a front end 11 and a rear end 12 in opposite directions; the grab clamp movable block 2 can slide between the front end 11 and the rear end 12 on the grab clamp fixed block 1, and can extend into the inner groove of the windproof ring 5 in the process of sliding toward the front end 11, and form a clamping space for clamping the windproof ring 5 with the front end 11; the limit pin 3 is used to be inserted into the grab clamp fixed block 1 to limit the sliding of the grab clamp movable block 2 after the clamping space is formed; the locking assembly 4 is arranged on the grab clamp fixed block 1 to lock or unlock the insertion and removal of the limit pin 3.

[0046] In the tank windproof ring hanger, the grab clamp movable block 2 slides a certain distance toward the front end portion 11 on the grab clamp fixed block 1, that is, it forms a clamping space with the front end portion 11; the limit pin 3 is penetrated through the grab clamp fixed block 1, that is, the grab clamp movable block 2 is limited to prevent the grab clamp movable block 2 from moving to ensure the existence of the clamping space; the locking component 4 locks the limit pin 3, that is, it realizes the positioning of the limit pin 3 to prevent the limit pin 3 from being separated from the grab clamp fixed block 1. After the lock is released, the limit pin 3 can be separated from the grab clamp fixed block 1, and at this time, the grab clamp movable block 2 can move to the rear end portion 12 to eliminate the clamping space.

[0047] When in use, the movable block 2 of the gripper slides toward the front end 11, and during the sliding process, extends into the inner groove of the wind-resistant ring 5 to support the wind-resistant ring 5, and cooperates with the front end 11 to clamp the wind-resistant ring 5; then the limit pin 3 is inserted into the gripper fixed block 1, and the limit pin 3 is locked by the locking assembly 4 to limit the position of the movable block 2 of the gripper. After the sling is assembled, the lifting equipment is connected to the gripper fixed block 1 through the connecting piece to realize the lifting of the wind-resistant ring 5; after the lifting is completed, the limit pin 3 is unlocked and the limit pin 3 is pulled out from the gripper fixed block 1, so that the separation of the sling and the wind-resistant ring 5 is completed.

[0048] It can be seen that compared with the existing technology, the tank wind-resistant ring lifting device clamps the wind-resistant ring 5 through the clamp fixed block 1 and the clamp movable block 2, limits the clamp movable block 2 through the limit pin 3, and positions the limit pin 3 through the locking assembly 4, thereby achieving effective clamping and fixing of the wind-resistant ring 5, eliminating the welding and grinding processes of the lifting ears, and is easy to disassemble and assemble, greatly improving work efficiency.

[0049] The following combination Figures 1 to 3 The structure and shape of the wind-resistant ring hanger for the storage tank provided in this embodiment are described in detail:

[0050] refer to Figure 1 and Figure 3 The gripper fixed block 1 includes a columnar connecting section 13, and the front end 11 and the rear end 12 are respectively fixed to the two ends of the connecting section 13; the front end 11 is L-shaped, and the inner wall of the vertical section is inlaid with a first anti-sliding block 6; the rear end 12 is provided with a connecting hole 121. The gripper movable block 2 is also L-shaped, and a square hole is provided on the vertical section, through which it is sleeved on the gripper fixed block 1, and a second anti-sliding block 7 is inlaid on the inner wall of the horizontal section.

[0051] Combination Figure 1As shown, when clamping the anti-wind ring 5, as the grabbing clamp movable block 2 slides, the second anti-sliding block 7 will synchronously move to the inner side of the anti-wind ring 5, and the first anti-sliding block 6 will contact the outer side of the anti-wind ring 5. In this way, after the grabbing clamp fixed block 1 and the grabbing clamp movable block 2 cooperate to clamp the anti-wind ring 5, the first anti-sliding block 6 and the second anti-sliding block 7 can prevent the anti-wind ring 5 from sliding, thereby ensuring the stability of the clamping of the anti-wind ring 5.

[0052] Regarding the locking component 4, specifically:

[0053] refer to Figures 1 to 3 The locking assembly 4 includes a pull rod 41 and a magnetic member 42; the pull rod 41 is inserted into the gripper fixing block 1 and can slide in the gripper fixing block 1 along its own axial direction; the magnetic member 42 is fixed to the pull rod 41, and is used to be magnetically connected to the limit pin 3, and can be separated from the limit pin 3 when the pull rod 41 is pulled.

[0054] Specific, combined Figure 3 As shown, the grasping forceps fixing block 1 is provided with a hole penetrating through itself and a countersunk hole connected to the hole, wherein the former is used to pass the pull rod 41, and the latter is used to accommodate the magnetic member 42; optionally, the magnetic member 42 adopts a magnetic nut, and a limiting groove is provided on its upper end surface along the radial direction of the magnetic nut; the upper end of the pull rod 41 is threadedly connected to the magnetic nut, and the lower end passes through the hole, and a cross bar is fixed on it to prevent the pull rod 41 from being separated from the grasping forceps fixing block 1 when it moves upward.

[0055] As mentioned above, the limit pin 3 includes an L-shaped plug-in portion and a U-shaped connecting portion; one section of the plug-in portion is used to be inserted into the grasping clamp fixing block 1, and the free end of the other section is vertically connected to one end of the connecting portion; the connecting portion is used to be inverted on the grasping clamp fixing block 1, so that the bottom section of the U-shaped structure, that is, the horizontal section, is in the limit groove, thereby realizing a magnetic connection with the magnetic nut.

[0056] When applied, combine Figure 1 As shown, first slide the grabbing clamp movable block 2 on the grabbing clamp fixed block 1, and after sliding until the horizontal section of the grabbing clamp movable block 2 extends into the inner groove of the wind-resistant ring 5 and the outer side of the wind-resistant ring 5 contacts the front end 11, insert the limit pin 3 into the grabbing clamp fixed block 1; then, use the section of the plug-in portion inserted into the grabbing clamp fixed block 1 as the rotation axis, rotate the limit pin 3, so that the connecting portion is inverted on the grabbing clamp fixed block 1, and at the same time, the connecting portion contacts the limit groove surface of the magnetic nut.

[0057] Continuing from the above, after assembling the lifting device, connect the lifting equipment to the connection hole 121 on the right side of the grab clamp fixed block 1 through the connecting piece to lift the anti-wind ring 5. When lifting the anti-wind ring 5, the magnetic nut attracts the limit pin 3 to prevent the limit pin 3 from falling off the grab clamp fixed block 1 due to flipping, thereby ensuring the effectiveness of the limit pin 3 in limiting the grab clamp movable block 2, thereby preventing the grab clamp movable block 2 from moving during the lifting process. After the lifting is completed, pull the pull rod 41 downward to separate the magnetic nut from the limit pin 3. At this time, rotate the limit pin 3 to pull the limit pin 3 out of the grab clamp fixed block 1, and then slide the grab clamp movable block 2 toward the rear end 12 to release the clamp of the lifting device from clamping the anti-wind ring 5.

[0058] It can be seen from the above that the storage tank windproof ring hoist clamps and fixes the storage tank windproof ring 5 through the clamp fixed block 1 and the clamp movable block 2, limits the clamp movable block 2 through the limit pin 3, positions the limit pin 3 through the magnetic nut, and controls the movement of the magnetic nut through the pull rod 41. The storage tank windproof ring hoist can be hoisted at any position on the upper side of the storage tank windproof ring 5, and the hoisting is safe, stable and efficient.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
