Description

Technical Field

[0001] The utility model relates to the technical field of C-type slings, in particular to a novel C-type sling. Background Art

[0002] C-type sling usually refers to a specially designed sling used for lifting, handling or fixing operations in the fields of industry, construction, etc. Its name comes from the shape of the letter "C" presented by its appearance.

[0003] During use of the existing C-type sling, the lower end of the sling is inserted into the middle of the steel coil, and then the external lifting equipment drives the steel coil to move through the sling. Since one end of the sling is an open structure, there is inertia during the movement of the steel coil. When the lifting equipment suddenly stops, the steel coil is easily detached from the open end of the sling due to inertia, posing a safety hazard. Utility Model Content

[0013] The beneficial technical effects are:

[0014] By setting a limiting mechanism and a shielding mechanism, when hoisting the steel coil, the hook can enter the steel coil from one end of the steel coil.

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0021] like Figure 1-Figure 3As shown, a novel C-type sling provided in this embodiment includes a hook 1, two sets of connecting mechanisms 2 are symmetrically installed on the top of the hook 1, a supporting mechanism 3 is installed above the bottom of the hook 1, a limiting mechanism 4 is installed on one side below the top of the hook 1, and a shielding mechanism 5 is connected to the limiting mechanism 4, the limiting mechanism 4 includes a main rod 401 fixedly connected to the hook 1, the main rod 401 can support the limiting rod 404, an upper connecting seat 402 is installed at the bottom of the main rod 401, and a lower connecting seat 403 is hinged below the upper connecting seat 402 through a torsion spring, so that the lower connecting seat 403 can drive the limiting rod 404 to rotate along the upper connecting seat 402. The lower connecting seat 403 is movable, and a limiting rod 404 is fixed at the bottom end of the lower connecting seat 403, and the limiting rod 404 can block the steel coil. The blocking mechanism 5 includes a baffle 501 located on one side of the upper connecting seat 402 and the lower connecting seat 403. The baffle 501 can block the limiting rod 404 to prevent the limiting rod 404 from rotating during the lifting process. A connecting frame 502 is installed on one side of the baffle 501, and the connecting frame 502 can drive the baffle 501 to rise and fall vertically. A guide rod 503 runs through the connecting frame 502, and a reset spring 504 is fixed on the outer side of the guide rod 503. The reset spring 504 can reset the connecting frame 502, thereby resetting the baffle 501.

[0022] like Figure 1 As shown, the connecting mechanism 2 includes a mounting seat 201 fixed on the top of the hook 1, and a lifting ring 202 is fixed on the top of the mounting seat 201, so that the lifting ring 202 can be fixed on the top of the hook 1 through the mounting seat 201, and then the lifting equipment is connected to the hook 1 through the lifting ring 202.

[0023] like Figure 1 As shown, the support mechanism 3 includes a support seat 301 fixed on the hook 1. The support seat 301 is a semicircular structure, which can contact the inside of the steel coil through the support seat 301 to improve the fit.

[0024] like Figure 1 As shown, a plurality of grooves 302 for increasing friction are provided on the support seat 301 , and the friction between the support seat 301 and the steel coil can be increased through the grooves 302 .

[0025] like Figure 1-Figure 3 As shown, the length of the limiting rod 404 is less than that of the main rod 401 , and the adjacent ends of the limiting rod 404 and the main rod 401 are both arc-shaped structures, which can ensure the smoothness of the limiting rod 404 when rotating.

[0026] like Figure 1-Figure 2 As shown, the connecting frame 502 is slidably connected to the guide rod 503, and an empty slot for the movement of the connecting frame 502 is opened on the main rod 401, one end of the return spring 504 is fixedly connected to the upper connecting seat 402, and the other end of the return spring 504 is fixedly connected to the connecting frame 502, so that the connecting frame 502 can move along the guide rod in the empty slot, thereby driving the baffle 501 to rise and fall.

[0027] like Figure 1-Figure 2 As shown, the connecting frame 502 is a side U-shaped structure, and the bottom end of the connecting frame 502 is located at one side of the lower connecting seat 403, so as to facilitate the steel coil to lift the connecting frame 502.

[0028] Working principle of the device: When the device is used, the lifting ring 202 is fixed to the top of the hook 1 through the mounting seat 201, and then the lifting equipment is connected to the hook 1 through the lifting ring 202. After the connection is completed, the lifting device drives the hook 1 to move to the steel coil, and then the bottom end of the hook 1 is inserted into the center of the steel coil;

[0029] During the insertion process, the limit rod 404 contacts with the steel coil and is squeezed to drive the lower connecting seat 403 to rotate along the upper connecting seat 402, thereby rotating the limit rod 404, which facilitates the hook 1 to smoothly enter the steel coil. At this time, the limit rod 404 and the upper connecting seat 402 are reset through the lower connecting seat 403, and the external lifting equipment moves the steel coil through the hook 1. During the movement, the baffle 501 is always located on one side of the lower connecting seat 403 to shield it, so that the limit rod 404 and the main rod 401 are in a horizontal direction, and the steel coil is shielded by the limit rod 404 to prevent the steel coil from detaching from the open end of the hook 1 due to inertia, which poses a safety hazard.

[0030] After the movement is completed, the steel coil is placed on the ground by the lifting equipment, and the hook 1 is continuously lowered. During the falling process of the hook 1, the connecting frame 502 contacts the steel coil and moves along the guide rod under the extrusion force. The movement of the connecting frame 502 drives the baffle 501 to rise and move to above the lower connecting seat 403. At this time, the hook 1 can be pulled outward to separate it from the steel coil. After the separation is completed, the connecting frame 502 and the baffle 501 are reset by the reset spring 504.

[0031] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
