Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a C-type hoist. Background Art

[0002] Most of the C-type slings currently in use are single-arm integral type. For example, the prior art publication number: CN220245296U discloses a C-type sling, which includes a sling body, wherein an opening is provided on one side of the sling body, and a placement portion is provided on the sling body, and the placement portion is used to place the coiled steel; it also includes a connecting piece and a protective piece, wherein the placement portion of the sling body is located on one side of the opening and has a first slot, and the placement portion of the sling body is also provided with a second slot connected to the first slot; the connecting piece is hinged in the first slot, and one end of the connecting piece passes through and extends from the second slot to the inner area of ​​the opening; the protective piece is fixedly installed at one end of the connecting piece away from the second slot, and the protective piece is arranged toward the opening side and extends outward from the first slot; when the coiled steel is placed on the placement portion, the surface of the coiled steel abuts against the connecting piece and causes the connecting piece to rotate relative to the sling body, driving the protective piece to rotate and abut against the side wall of the steel coil.

[0003] Although the single-arm integral sling has strong load-bearing capacity, its lifting stability is not good. If it is directly applied to the logistics lifting process, the objects with larger lifting volume are prone to shaking. Utility Model Content

[0004] The technical problem to be solved by the utility model is that although the existing single-arm integral sling has strong load-bearing capacity, the stability of the lifting is not good. If it is directly applied to the logistics lifting process, the object is easy to shake when the lifting volume is large, and there is a problem of easy falling off.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A C-type sling comprises an L-shaped lifting arm, a lifting lug, a side arm and a load-bearing arm. The side arm is triangular, a stepped hole a is provided on the back of the side arm near the top corner, and a plurality of stepped holes b are provided on the side near the bottom edge at intervals.

[0007] The boom is embedded in the stepped hole a, and the load-bearing arm is embedded in the stepped hole b. The boom and the load-bearing arm are threadedly connected with locking bolts at one end close to the boom.

[0008] Furthermore, a trapezoidal hole is provided in the middle of the side arm, and the cross section of the side arm is an "I" shape.

[0009] Furthermore, the load-bearing arm is tubular and has a clamping hole at one end away from the side arm. A zigzag elastic clamping strip is embedded in the inner surface of the load-bearing arm at the position of the clamping hole. The top of the elastic clamping strip is raised away from the end, and the bottom of the elastic clamping strip is fixedly connected to a right-angled triangular limit block near the end. A limit groove matching the triangular limit block is provided on the inner surface of the load-bearing arm at the position of the triangular limit block.

[0010] Working principle and beneficial effects: By increasing the number of load-bearing arms to increase the contact area between the sling and the hoisted object, the stability of the hoisting is improved, and the boom, side arm and load-bearing arm in the sling are all designed separately, which can be easily replaced and maintained to reduce the subsequent maintenance cost or adjust the number of load-bearing arms appropriately according to the hoisting requirements to reduce the working power consumption.

[0019] like Figure 1-3 As shown,

[0020] Example 1

[0021] A C-type sling comprises an L-shaped jib 1, a lifting lug 2, a side arm 3 and a load-bearing arm 4. The side arm 3 is triangular, and a stepped hole a is provided on the back of the side arm 3 near the top corner, and a plurality of stepped holes b are provided on the side near the bottom edge at intervals.

[0022] The boom 1 is embedded in the stepped hole a, and the load-bearing arm 4 is embedded in the stepped hole b. The boom 1 and the load-bearing arm 4 are threadedly connected with locking bolts at one end close to the boom 1.

[0023] By increasing the number of load-bearing arms 4 to increase the contact area between the sling and the suspended object, the stability of the lifting is improved, and the lifting arm 1, side arm 3 and load-bearing arm 4 in the sling are all designed separately, which can be convenient for replacement and maintenance to reduce the later maintenance cost or the number of load-bearing arms 4 can be appropriately adjusted according to the lifting needs to reduce the weight of the sling and reduce the working power consumption. A trapezoidal hole is opened in the middle of the side arm 3, and the cross-section of the side arm 3 is "I"-shaped to increase the load-bearing capacity of the side arm 3.

[0024] like Figure 4 In embodiment 2, the load-bearing arm 4 is tubular and has a clamping hole 5 at one end away from the side arm 3. A zigzag elastic clamping strip 6 is embedded in the inner surface of the load-bearing arm 4 at the position of the clamping hole 5. The top of the elastic clamping strip 6 is raised away from the end, and the bottom of the elastic clamping strip 6 is fixedly connected with a right-angled triangular limit block 7 near the end. A limit groove matching the triangular limit block 7 is provided on the inner surface of the load-bearing arm 4.

[0025] The specially designed elastic clip strip 6 can prevent the hoisted object from slipping and improve the safety of hoisting.
