Description

Technical Field

[0001] This utility model relates to the field of lifting clamp technology, specifically to a lifting clamp for film rolls. Background Technology

[0002] Lifting refers to the process of using lifting equipment, such as cranes, tower cranes, and gantry cranes, to move heavy objects from one place to another. Lifting operations are widely used in construction, equipment installation, logistics transportation, mining, and other fields. Lifting clamps are mainly used to hold and secure heavy objects and are used in conjunction with lifting equipment to improve the efficiency and safety of lifting operations.

[0003] In existing technologies, when hoisting and transporting large film rolls, two lifting rings are usually placed on opposite ends of the film roll's shaft. During transport, if the center of gravity shifts, the opposite ends of the film roll's shaft can easily slide off the two lifting rings if they are not secured, potentially causing the film roll to fall from a height and posing a certain safety risk.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] To address the technical problem in existing technologies where film rolls are prone to falling from heights during hoisting if the two ends of the film roll's pivot are not secured, this invention provides a film roll hoisting clamp that can secure the opposite ends of the film roll, ensuring its stability during hoisting.

[0027] Please see Figures 1-5 , Figures 1-5A lifting clamp for a film roll according to one embodiment of the present invention includes an adjustment mechanism 1 and two fixing mechanisms 2. The adjustment mechanism 1 includes two translation members 11, which are capable of relative movement. The two fixing mechanisms 2 are respectively installed on the two translation members 11. The fixing mechanism 2 includes a support member 21 and a clamping member 22. The support member 21 is fixedly connected to the translation member 11. The support member 21 has a positioning cavity 21a. The clamping member 22 is installed on the support member 21 and can fix one end of the rotating shaft of the film roll in the positioning cavity 21a.

[0028] In actual use, this lifting clamp needs to be used in conjunction with a gantry crane to lift and transport film roll A. By moving the two translation members 11 away from each other, the two positioning cavities 21a are aligned with the opposite ends of the rotating shaft of the film roll. Then, by moving the two translation members 11 closer together, the opposite ends of the rotating shaft of the film roll can be inserted into the two positioning cavities 21a respectively. Subsequently, the clamping members 22 fix the opposite ends of the rotating shaft in the positioning cavities 21a respectively.

[0029] It should be noted that, in one embodiment, the support member 21 includes a support rod 211 and a support base 212. One end of the support rod 211 is fixedly connected to the translation member 11, and the other end of the support rod 211 is fixedly connected to the support base 212. The support base 212 is provided with a positioning cavity 21a, and the clamping member 22 is installed on the support base 212.

[0030] It should be noted that the clamping member 22 is not limited to a specific structure. As long as it can fix one end of the rotating shaft that passes through the positioning cavity 21a, no further details will be provided here.

[0031] Specifically, the clamping member 22 includes a base 221, two first clamping plates 222, two transmission rods 223, a second clamping plate 224, and an adjusting member 225. The base 221 is installed in the positioning cavity 21a. The two first clamping plates 222 are located in the positioning cavity 21a and are both hinged to the base 221. One end of each of the two transmission rods 223 is hinged to the two first clamping plates 222, and the other end is hinged to the second clamping plate 224. The two first clamping plates 222 and the second clamping plate 224 enclose a fixed space. The adjusting member 225 is installed on the base 221 and connected to the second clamping plate 224. The adjusting member 225 is used to drive the second clamping plate 224 to move to adjust the size of the fixed space.

[0032] It is understandable that when one end of the rotating shaft passes through the positioning cavity 21a and the second clamping plate 224 supports one end of the rotating shaft, the second clamping plate 224 can be moved upward by the adjusting member 225 to fix one end of the rotating shaft.

[0033] In one embodiment, the adjusting member 225 includes a telescopic part 2251, which is mounted on the seat 221 and its output end extends into the positioning cavity 21a and is connected to the second clamping plate 224.

[0034] It should be noted that the telescopic part 2251 is an electric cylinder. Of course, in other embodiments, the telescopic part 2251 can also be a pneumatic cylinder or a hydraulic cylinder.

[0035] In another embodiment, the adjusting member 225 includes an adjusting screw 2252 and a drive wheel 2253. The adjusting screw 2252 is threadedly rotatably connected to the seat 221. One end of the adjusting screw 2252 extends into the positioning cavity 21a and is rotatably connected to the second clamping plate 224. The other end is located outside the positioning cavity 21a and is fixedly connected to the drive wheel 2253.

[0036] Understandably, two operators can simultaneously rotate the two adjusting screws 2252 to drive the second clamping plate 224 upward to fix one end of the film roll's shaft.

[0037] It should be noted that, based on the above scheme, the surfaces of the two first clamping plates 222 and the second clamping plates 224 that are in contact with the rotating shaft of the film roll are provided with gaskets, wherein the gaskets are elastic rubber gaskets.

[0038] It should be noted that the adjustment mechanism 1 is not limited to a specific structure. In one embodiment, the adjustment mechanism 1 includes an adjustment seat 12, a bidirectional lead screw 13, and a rotating handwheel 14. The bidirectional lead screw 13 is rotatably mounted on the adjustment seat 12, and the rotating handwheel 14 is fixedly connected to one end of the bidirectional lead screw 13. Both translation members 11 are slidably connected to the adjustment seat 12, and the two translation members 11 are also threadedly rotatably connected to the two threaded portions of the bidirectional lead screw 13.

[0039] Furthermore, the translation component 11 includes a sleeve 111 and a slider 112. The sleeve 111 is slidably sleeved on the adjusting seat 12 and connected to one end of the support rod 211. The slider 112 is fixed on the sleeve 111 and is threadedly connected to the bidirectional lead screw 13.

[0040] It is understood that the adjusting seat 12 has a strip-shaped hole along its length, and the slider 112 passes through the strip-shaped hole and is threadedly connected to the bidirectional lead screw 13 for rotation.

[0041] Specifically, the operator can manually rotate the bidirectional lead screw 13 to simultaneously drive the two translation components 11 to move relative to the adjusting seat 12, thereby driving the two translation components 11 to move closer or further apart.

[0042] Based on the above scheme, in order to facilitate the use of the lifting clamp and the overhead crane, specifically, the middle part of the adjusting seat 12 is provided with a lifting ring 121.

[0043] Based on the above scheme, the adjustment seat 12 is provided with a handle 122 at one end near the rotating handwheel 14; it can be understood that when the operator needs to rotate the bidirectional lead screw 13, he can hold the handle 122 with one hand and rotate the rotating handwheel 14 with the other hand.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
