Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to a weighing and anti-collision lifting tool. Background Art

[0002] Aluminum-plated film is formed by heating and melting aluminum metal to evaporation in a vacuum state, and aluminum atoms condense on the surface of polymer materials to form a thin film with an extremely thin aluminum layer. Commonly used aluminum-plated substrates include films such as polyester (PET), polypropylene (PP), polyamide (PA), polyethylene (PE), and polyvinyl chloride (PVC).

[0003] The existing production process is that the produced centralized collection film is wound on the air shaft of the casting machine. A crane is used to lift the produced substrate film roll (together with the air shaft) from the casting machine and transfer it to the coating machine, and then it is unwound for coating and rewound after coating.

[0004] When using a crane to lift the film roll (air shaft) in the prior art, mainly two types of lifting tools are used. One is a "冂"-shaped frame, with the top hung on the hook and the two bottom ends respectively sleeved on the two ends of the air shaft. This kind of lifting tool has good stability and is not easy to shake during the lifting process. However, when approaching the coating machine and placing the film roll at the corresponding position of the coating machine, the frame is easy to collide with the coating machine, affecting the operation of the equipment. The other is a crossbeam and two lifting straps. The two lifting straps are respectively lifted from the two ends of the air shaft and hung on the crossbeam. When using this kind of lifting tool, due to the long length of the lifting straps, the height of the crossbeam during lifting is much higher than the height of the staff, and it is not easy for the staff to hang the lifting straps on the crossbeam, so the usability is not good. In view of the above situation, we propose a lifting tool with anti-collision function. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the lifting tool used for lifting the film roll in the production of aluminum-plated film in the prior art is easy to have a rigid collision with the coating machine, affecting the operation of the equipment, and to propose a weighing and anti-collision lifting tool.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A weighing and anti-collision lifting tool includes a "冂"-shaped lifting frame. A crane scale is arranged at the top of the lifting frame. The lifting frame includes a crossbeam connected to the bottom of the crane scale. Two suspension rods are fixedly connected to both ends of the crossbeam, and an axle hanging buckle is arranged at the bottom of the suspension rod.

[0008] The suspension rod includes a straight pipe and a first buffer layer. The top of the straight pipe is fixedly connected to the crossbeam, and the surface of the straight pipe is wrapped with the first buffer layer.

[0009] Furthermore, the surface of the first buffer layer is wrapped with a second buffer layer, and the surface of the second buffer layer is wrapped with a third buffer layer.

[0010] Furthermore, the first buffer layer and the third buffer layer are hard sponges, and the second buffer layer is a plastic tube.

[0011] Furthermore, a plurality of separation grooves are provided on the side wall of the second buffer layer in the axial direction, the plurality of separation grooves are distributed in a cross shape, and the separation grooves penetrate the second buffer layer.

[0012] Furthermore, the shaft hanger includes a cross bar fixedly mounted on both ends of the straight tube side wall, both ends of the cross bar are provided with anti-slip columns, a lifting belt is hung on the cross bar, and the lifting belt is located on the inner side of the anti-slip column.

[0013] Furthermore, a pressing block is provided at the bottom of the straight tube, and a shaft groove corresponding to the gas expansion shaft is provided at the bottom of the pressing block;

[0014] A telescopic block is arranged on the top of the clamping block, the top of the telescopic block is connected to the working end of the hydraulic cylinder, guide blocks are arranged on both sides of the telescopic block, a guide groove is axially opened on the side wall of the straight tube, and the guide block is slidably connected to the guide groove.

[0016] Compared with the prior art, the utility model provides a weighing anti-collision sling, which has the following beneficial effects:

[0017] The utility model discloses a weighing anti-collision sling. When in use, the lifting equipment lifts the sling through the overhead crane scale, lifts the sling to the top of the film roll, and lifts the two ends of the air expansion shaft through the shaft hanging buckles. During the lifting process, when the suspension rod collides with the coating machine, the first buffer layer buffers the impact force of the collision, so that the rigid collision becomes an elastic collision, avoiding damage to the equipment, and having good stability. At the same time, the height of the shaft hanging buckle is flush with the air expansion shaft, which is convenient for staff to operate and has good usability.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figure 1-5 , a weighing and anti - collision sling of the present utility model includes a "冂"-shaped lifting frame. The top of the lifting frame is connected with an overhead crane scale 4 (commercially available) through a hook. A lifting ring is installed on the top of the overhead crane scale. During use, the hook of the crane hooks the lifting ring of the overhead crane scale.

[0028] The lifting frame includes a cross beam 1 connected to the bottom of the overhead crane scale 4. The two ends of the cross beam 1 are welded with suspension rods 2. The bottom of the suspension rod 2 is fixedly connected with a shaft sling buckle 3. During use, the lifting positions at both ends of the air shaft are lifted through the shaft sling buckle 3.

[0029] The suspension rod 2 includes a straight pipe 5 and a first buffer layer 6. The top of the straight pipe 5 is welded to the cross beam 1, and the straight pipe 5 and the cross beam 1 form a "冂" shape.

[0030] The surface of the straight pipe 5 is wrapped with a first buffer layer 6, and the surface of the cross beam 1 can also be wrapped with a first buffer layer 6. During lifting, the moving speed of the film roll is relatively slow. The impact of the suspension rod 2 on the coating machine during lifting is mainly the vibration effect caused by rigid collision. The first buffer layer 6 is used to absorb the vibration effect and convert the rigid collision into an elastic collision, thereby avoiding the failure of the coating machine due to the vibration effect.

[0031] The surface of the first buffer layer 6 is wrapped with the second buffer layer 7, and the surface of the second buffer layer 7 is wrapped with the third buffer layer 8. By increasing the number of buffer layers, the buffer effect is improved and the replacement cost is reduced.

[0032] Generally speaking, if this type of buffer material is damaged, it is mostly damaged from the outside to the inside. If a very thick buffer layer is selected to wrap the surface of the straight tube 5, when it is damaged, it needs to be replaced as a whole. The buffer layer in the application is divided into multiple layers. When wear occurs from the outside to the inside, the damaged buffer layers can be replaced according to the damage situation, and the intact buffer layer inside can continue to be used, thereby reducing the replacement cost.

[0033] The first buffer layer 6 and the third buffer layer 8 are hard sponges, and the second buffer layer 7 is a plastic tube.

[0034] The thickness of the first buffer layer 6 and the second buffer layer 8 is between 10mm and 15mm. The plastic tube can be a PC tube or a PVC tube. The thickness of the second buffer layer 7 is between 3-6mm, so that the plastic tube has higher mechanical strength than hard sponge and also has good elastic deformation ability.

[0035] Compared with using only the first buffer layer 6, the strength of the plastic tube is higher than that of the hard sponge, which can reduce the thickness requirement for the first buffer layer 6 and avoid the situation where only the first buffer layer 6 is installed and the first buffer layer 6 needs to be made particularly thick.

[0036] At the same time, since ordinary plastic pipes themselves are incompressible structures, the first buffer layer 6 here is used to buffer the impact force between the plastic pipe straight pipes 5 to avoid rigid collision between the plastic pipes and the straight pipes 5, while the third buffer layer 8 is used to buffer the rigid collision between the coating machine and the plastic pipe.

[0037] A plurality of separation grooves 71 are formed on the side wall of the second buffer layer 7 along the axial direction. The plurality of separation grooves 71 are distributed in a cross shape and penetrate the second buffer layer 7 .

[0038] The separation groove 71 penetrates the second buffer layer 7 axially and radially, so that the second buffer layer 7 is composed of multiple long strip structures with fan-shaped cross-sections. Compared with the ring structure, the long strip structure has better elastic deformation performance and is easier to restore to its original state after a collision, thereby extending the service life.

[0039] The shaft hanging buckle 3 includes a cross bar 9 fixedly mounted on both ends of the side wall of the straight tube 5 , both ends of the cross bar 9 are provided with anti-slip columns 10 , a lifting belt 11 is hung on the cross bar 9 , and the lifting belt 11 is located on the inner side of the anti-slip column 10 .

[0040] The anti-slip column 10 is welded to the positions of the two ends of the top of the cross bar 9 in the vertical direction, and the two ends of the lifting belt 11 are hung on the cross bar 9 between the suspension rod 2 and the anti-slip column 10.

[0041] When in use, first hang one end of the lifting belt 11 on one end of the cross bar 9. When the cross bar 9 moves to the top of the end of the air-inflating shaft, the other end of the lifting belt 11 is passed upward from the bottom of the end of the air-inflating shaft and hung on the other end of the cross bar 9 to lift the air-inflating shaft and the film roll.

[0042] A pressing block 12 is installed at the bottom of the straight tube 5 , and a shaft groove 13 corresponding to the gas expansion shaft is opened at the bottom of the pressing block 12 .

[0043] The shaft groove 13 is a U-shaped groove opening downward, and the axial direction of the shaft groove 13 is the same as the axial direction of the air expansion shaft and the crossbeam 1. When the lifting belt 11 lifts the film roll, the shaft groove 13 just covers the outside of the air expansion shaft to reduce the twisting of the film roll during the lifting process.

[0044] A telescopic block 15 is fixedly connected to the top of the clamping block 12, and the top of the telescopic block 15 is connected to the working end of the hydraulic cylinder 14. Guide blocks 16 are integrally formed on both sides of the telescopic block 15. A guide groove 17 is axially opened on the side wall of the straight tube 5, and the guide block 16 and the guide groove 17 are slidably connected.

[0045] After the lifting belt 11 is passed around the gas expansion shaft, the hydraulic cylinder 14 is controlled to extend downward, driving the telescopic block 15 to extend downward, driving the clamping block 12 to extend downward, so that the shaft groove 13 is against the gas expansion shaft, and the gas expansion shaft is pressed between the shaft groove 13 and the lifting belt 11, reducing the activity space of the gas expansion shaft, further improving the stability during the lifting process, and reducing twisting.

[0046] Based on this situation, the specification of the lifting belt 11 is selected to be a larger weight specification. For example, a lifting belt with a rated load of 3 tons is normally used, but a lifting belt with a rated load of 5 tons can be used in this application.

[0047] The crossbeam 1 includes a vertical plate and a horizontally arranged circular tube. The top of the vertical plate is connected to the overhead crane scale 4. The circular tube is wrapped around the outside of the bottom of the vertical plate. The top of the straight tube 5 is fixedly connected to the circular tube.

[0048] After the bottom end of the vertical plate passes through the round tube, it is welded to the bottom of the inner wall of the round tube. Inclined ribs are set at both ends of the top of the vertical plate, so that the middle of the top of the vertical plate is a horizontal edge, the two sides of the top of the vertical plate are inclined ribs, and the two ends of the vertical plate are vertical ribs. The round tube makes the vertical plate have good resistance to torsional deformation in the horizontal direction.

[0049] Working principle: When in use, the hook of the lifting equipment lifts the device through the lifting ring on the top of the overhead crane scale 4, lifts the device to the top of the substrate film roll, removes one end of the lifting belt 11, passes it around from the bottom of the gas expansion shaft, and re-hangs it on the cross bar 9, then starts the working end of the hydraulic cylinder 14 to extend downward, driving the telescopic block 15 and the clamping block 12 to extend downward, so that the shaft groove 13 is pressed on the top of the gas expansion shaft, and then the lifting equipment lifts the substrate film roll upward.

[0050] When the base film roll is hoisted onto the coating machine, if the hoist rod 2 collides with the coating machine, the first buffer layer 6, the second buffer layer 7, and the third buffer layer 8 can effectively convert the rigid collision into an elastic collision, reduce the vibration of the coating machine, and achieve an anti-collision effect.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
