Description

Technical Field

[0001] This utility model relates to the field of steel strip coil protection technology, and in particular to a steel strip anti-loosening device. Background Technology

[0002] With the development of iron and steel metallurgical technology, the application of ultra-high strength steel with high yield strength is becoming increasingly widespread. Due to the extreme elasticity of ultra-high strength steel, the steel coil is prone to loosening or even bursting during the coiling process, especially small steel coils. Without effective anti-loosening measures, there are certain safety hazards. Therefore, a steel strip anti-loosening device is needed to improve the safety factor.

[0003] Existing anti-loosening devices for steel strips mostly use clamping mechanisms for fixing, which are complicated to operate, inconvenient to assemble, and costly.

[0004] A device for preventing loosening of ultra-high strength steel coiling is disclosed in Chinese patent document CN217726694U. This device includes a frame, an upper swing arm pressure roller assembly mounted on the frame, a lower swing arm pressure roller assembly, an upper pressure plate assembly mounted on the upper swing arm pressure roller assembly, and a lower pressure plate assembly mounted on the lower swing arm pressure roller assembly. The upper pressure plate assembly is rotatably mounted on the end of the upper swing arm pressure roller assembly and is used to clamp the steel coil. The lower pressure plate assembly is rotatably mounted on the end of the lower swing arm pressure roller assembly and is also used to clamp the steel coil. In this device, the pressure plate is mounted on the swing arm of the pressure roller and, together with the pressure roller, presses down to prevent the ultra-high strength steel from loosening. The pressure plate surface has a wear-resistant liner, and there is sliding friction between the pressure plate and the steel coil. Under the same pressing force, the friction is greater, preventing the steel coil from loosening. The device is compact, simple in structure, and easy to install and maintain. However, this device uses a robotic arm for anti-loosening reinforcement, which results in higher costs.

[0005] To address the shortcomings of the existing technology, providing a steel strip anti-loosening device is a problem worthy of research. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing steel strip anti-loosening devices, which mostly use clamping mechanisms for fixing, are complicated to operate and inconvenient to assemble, and have high costs. This utility model provides a steel strip anti-loosening device that achieves the technical effects of simple installation and high safety.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A steel strip anti-loosening device includes a steel strip roll, sleeves fitted on both sides of the steel strip roll, a sealing plate fixedly connected to the end of the sleeve, a connecting plate fixedly connected to the outside of the sleeve and the sealing plate, a reinforcing mechanism disposed between the two sleeves, and a support mechanism disposed on the outside of the sleeve.

[0009] The sleeve is U-shaped, and the inner shape of the sleeve is adapted to the outer shape of one side of the steel strip roll. The shape of the closing plate is adapted to the shape of the end opening of the sleeve. The outer side of the opening of the sleeve and the outer side of the closing plate are provided with first threaded holes. The closing plate is fixedly connected to the sleeve through the first threaded holes and bolts. By setting the sleeve and closing plate on both sides of the steel strip roll, the steel strip roll is tightened, reducing the probability of the steel strip roll loosening.

[0010] The reinforcement mechanism includes several connecting steel pipes fixedly connected between two sleeves, and a reinforcement steel pipe passing through the connecting steel pipes;

[0011] The connecting steel pipes are distributed in groups between the sleeves, and each group of connecting steel pipes is arranged in a ring. The reinforcing steel pipe passes through the intersection of the connecting steel pipes and passes through the connecting steel pipe and the connecting plate to fix the sleeve and the sealing plate.

[0012] The connecting plate is X-shaped, and a circular hole is opened at the center of each connecting plate. The diameter of the circular hole is adapted to the diameter of the reinforcing steel pipe. One end of the reinforcing steel pipe is fixedly connected to a limiting disc, and the other end of the reinforcing steel pipe is provided with an external thread. The corresponding circular hole on one side is provided with an internal thread. The external thread on the reinforcing steel pipe is threadedly connected to the internal thread on the circular hole. By setting the connecting plate between the sleeve and the sealing plate, the sleeves on both sides are fixedly connected, thereby improving the overall strength of the anti-loosening coil.

[0013] The outer side of each sleeve is fixedly connected with reinforcing ribs. The shape and position of the reinforcing ribs correspond to the shape and position of the end of the connecting plate. The reinforcing ribs increase the strength of the sleeve and, together with the connecting plate, improve the overall compressive load resistance of the device and enhance its stability.

[0014] The support mechanism includes a support rod assembled and connected to the outside of the coil sleeve, and a base plate fixedly connected to the bottom of the support rod. The support rod provides support and limits the two sides of the steel strip coil to prevent the steel strip coil from rolling and causing damage to surrounding equipment.

[0015] The bottom height of the base plate is equal to the bottom height of the steel strip coil. One end of the base plate extends outward from the steel strip coil. The T-shaped support structure can provide greater resistance to keep the steel strip coil stable, while preventing the steel strip coil from unraveling during rotation and causing safety accidents.

[0016] The shape of the top of the support rod is adapted to the shape of the outer side of the sleeve. Several second threaded holes are opened on the top of the support rod and the outer side of the sleeve. The support rod and the sleeve are fixedly connected by bolts through the second threaded holes. The assembled support rod and the sleeve are further fixedly connected by bolts so that the support structure can remain stable when subjected to external forces. The assembled support mechanism is simple in structure, easy to install, and low in cost, making it suitable for mass application.

[0017] A pad is fixedly connected to the top of the inner side of the base plate. The top of the pad is curved, and the shape of the curved top of the pad matches the shape of the outer side of the bottom of the steel strip coil. The pad is made of high-density polyurethane foam. By setting the pads on both sides of the bottom of the steel strip coil, a stable support structure is formed to match the curved surface of the bottom of the steel strip coil, preventing the steel strip coil from rolling. In addition, the pad made of high-density polyurethane foam has the ability to buffer vibration, which can reduce the impact of vibration on the steel strip coil during transportation and prevent the steel strip coil from unraveling due to vibration.

[0018] Positive and beneficial effects:

[0019] 1. This steel strip anti-loosening device, equipped with a sleeve and a closing plate, tightens the steel strip roll, reducing the probability of the steel strip roll loosening. The connecting plate fixes the sleeves on both sides, improving the overall strength of the anti-loosening device. A reinforcing steel pipe with external threads passes between the two connecting plates, connecting the two connecting plates and the connecting steel pipe together, further fixing the sleeve and closing plate, and further reinforcing the sleeve to improve overall stability.

[0020] 2. The steel strip anti-loosening device has support rods with base plates on both sides to support and limit the steel strip roll on both sides, preventing the steel strip roll from rolling and causing damage to surrounding equipment.

[0021] 3. The steel strip anti-loosening device has pads on both sides of the bottom of the steel strip roll, which form a stable support structure with the arc surface of the bottom of the steel strip roll to prevent the steel strip roll from rolling. The pads made of high-density polyurethane foam have the ability to buffer vibration, which can reduce the impact of vibration on the steel strip roll during transportation and prevent the steel strip roll from unraveling due to vibration.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] Example 1

[0032] like Figures 1 to 7 As shown, a steel strip anti-loosening device includes a steel strip roll 1, a roll sleeve 2 sleeved on both sides of the steel strip roll 1, a sealing plate 3 fixedly connected to the end of the roll sleeve 2, a connecting plate 4 fixedly connected to the outside of the roll sleeve 2 and the sealing plate 3, a reinforcing mechanism disposed between the two roll sleeves 2, and a support mechanism disposed on the outside of the roll sleeve 2.

[0033] like Figure 7 As shown, the sleeve 2 is U-shaped. The inner shape of the sleeve 2 is adapted to the outer shape of one side of the steel strip roll 1. The shape of the sealing plate 3 is adapted to the shape of the end opening of the sleeve 2. The outer side of the opening of the sleeve 2 and the outer side of the sealing plate 3 are provided with first threaded holes 5. The sealing plate 3 is fixedly connected to the sleeve 2 through the first threaded holes 5 and bolts. By setting the sleeve 2 and sealing plate 3 on both sides of the steel strip roll 1, the steel strip roll 1 is tightened, reducing the probability of the steel strip roll 1 loosening.

[0034] like Figures 5 to 7 As shown, the reinforcement mechanism includes several connecting steel pipes 6 fixedly connected between the two sleeves 2, and a reinforcement steel pipe 7 passing through the connecting steel pipes 6;

[0035] The connecting steel pipes 6 are distributed in groups between the sleeves 2, and each group of connecting steel pipes 6 is arranged in a ring. The reinforcing steel pipes 7 pass through the intersection of the connecting steel pipes 6. By setting the connecting steel pipes 6 between the sleeves 2, the sleeves 2 on both sides are further connected and fixed, which improves the overall stability and load-bearing capacity of the anti-loosening device. The reinforcing steel pipes 7 pass through the connecting steel pipes 6 and the connecting plate 4 to fix the sleeves 2 and the closing plate 3.

[0036] like Figures 1 to 4 As shown, the connecting plate 4 is X-shaped, and a circular hole is opened at the center of each connecting plate 4. The diameter of the circular hole is adapted to the diameter of the reinforcing steel pipe 7. One end of the reinforcing steel pipe 7 is fixedly connected to the limiting disc 8, and the other end of the reinforcing steel pipe 7 is provided with an external thread. An internal thread is provided on the circular hole on the corresponding side. The external thread on the reinforcing steel pipe 7 is threadedly connected to the internal thread on the circular hole. By setting the connecting plate 4 between the sleeve 2 and the sealing plate 3, the sleeves 2 on both sides are fixedly connected, thereby improving the overall strength of the anti-loosening coil. The reinforcing steel pipe 7 with external thread passes through between the two connecting plates 4, connecting the two connecting plates 4 and the connecting steel pipe 6 together, and further fixing the sleeve 2 and the sealing plate 3, thereby further reinforcing the sleeve 2 and improving the overall stability.

[0037] Example 2

[0038] like Figures 1 to 2 As shown, reinforcing ribs 9 are fixedly connected to the outer side of the sleeve 2. The shape and position of the reinforcing ribs 9 correspond to the shape and position of the end of the connecting plate 4. By setting reinforcing ribs 9 on the outer side of the sleeve 2, the strength of the sleeve 2 is increased, and in conjunction with the connecting plate 4, the overall compressive load resistance of the device is improved, thus enhancing its stability.

[0039] Example 3

[0040] like Figures 4 to 7 As shown, the support mechanism includes a support rod 10 assembled and connected to the outside of the sleeve 2, and a base plate 11 fixedly connected to the bottom of the support rod 10. By setting support rods 10 with base plates 11 on both sides of the anti-loosening device, the two sides of the steel strip roll 1 are supported and limited, so as to avoid the steel strip roll rolling and causing damage to the surrounding equipment.

[0041] like Figures 1 to 7 As shown, the bottom height of the base plate 11 is equal to the bottom height of the steel strip coil 1. One end of the base plate 11 extends outward from the steel strip coil 1. By extending one end of the base plate 11 outward, the base plate 11 and the support rod 10 cooperate to form a T-shaped structure. When the steel strip coil 1 is subjected to external force and is about to rotate, the T-shaped support structure can provide greater resistance to keep the steel strip coil stable, while avoiding the situation where the steel strip coil will unravel during rotation and cause a safety accident.

[0042] like Figures 1 to 2As shown, the shape of the top of the support rod 10 matches the shape of the outer side of the sleeve 2. Several second threaded holes 12 are provided on the top of the support rod 10 and the outer side of the sleeve 2. The support rod 10 and the sleeve 2 are fixedly connected by bolts through the second threaded holes 12. The assembled support rod 10 and the sleeve 2 are further fixedly connected by bolts so that the support structure can remain stable when subjected to external forces. The assembled support mechanism has a simple structure, is easy to install, and has low cost, making it suitable for mass application.

[0043] like Figures 4 to 7 As shown, a pad 13 is fixedly connected to the top of the inner side of the base plate 11. The top of the pad 13 is an arc surface, and the shape of the arc surface of the top of the pad 13 matches the shape of the outer side of the bottom of the steel strip roll 1. The pad 13 is made of high-density polyurethane foam. By setting the pads 13 on both sides of the bottom of the steel strip roll 1, a stable support structure is formed to match the arc surface of the bottom of the steel strip roll 1, preventing the steel strip roll 1 from rolling. The pad 13 made of high-density polyurethane foam has the ability to buffer vibration, which can reduce the impact of vibration on the steel strip roll 1 during transportation and prevent the steel strip roll 1 from unraveling due to vibration.

[0044] The working principle of this utility model is as follows:

[0045] S1. Place the sleeve 2 on the steel strip roll 1 and mate the other side with the sleeve 2. Connect the bolt with the first threaded hole 5 to fix the two together. The sleeve 2 and the closing plate 3 are installed on both sides of the steel strip roll 1 to tighten the steel strip roll 1 and reduce the probability of the steel strip roll 1 loosening.

[0046] S2. Pass the reinforcing steel pipe 7 through the connecting plate 4 and the connecting steel pipe 6, and thread the reinforcing steel pipe 7 to the connecting plate 4 on the other side. Fix the sleeve 2 and the sealing plate 3 to the sleeve 2 to further reinforce it and improve the overall stability.

[0047] S3. Assemble the support rod 10 with the outer side of the sleeve 2 and nail the bolt into the second threaded hole 12 to complete the fixed connection. The base plate 11 and the support rod 10 cooperate to form a T-shaped structure. When the steel strip roll 1 is subjected to external force and is about to rotate, the T-shaped support structure can provide greater resistance to keep the steel strip roll stable, while avoiding the situation where the steel strip roll will spread out during rotation and cause a safety accident.

[0048] S4 and pad 13 cooperate with the arc surface at the bottom of the steel strip roll 1 to form a stable support structure, preventing the steel strip roll 1 from rolling. The pad 13, made of high-density polyurethane foam, has the ability to buffer vibration, which can reduce the impact of vibration on the steel strip roll 1 during transportation and prevent the steel strip roll 1 from unraveling due to vibration.
