Description

Technical Field

[0001] The utility model relates to the field of lifting equipment, in particular to a high-temperature steel coil clamp. Background Art

[0002] Finished steel coils are often lifted using coil clamps. For existing coil clamps, see patent application number CN202023328874.X. During lifting, the coil clamp is moved to the coil location, then its two arms are inserted into the inner ring of the coil. The arms of the coil clamp clamp together, firmly gripping the coil and transferring it.

[0003] However, to ensure the safe lifting of steel coils, it is necessary to ensure that the clamp arm extends smoothly into the steel coil. To verify whether the clamp arm has extended into the steel coil, a sensor is installed at the free end of the clamp arm to determine whether the clamp arm has extended into the steel coil. However, the newly rolled steel coil has a very high temperature, which can damage the sensor and make it unable to work properly.

[0004] Therefore, how to prevent high temperature environments from damaging sensors is a technical problem that needs to be solved urgently. Utility Model Content

[0005] The purpose of the present invention is to overcome the above technical deficiencies and to provide a high-temperature steel coil clamp to solve the technical problem in the prior art of how to prevent the sensor from being damaged by a high-temperature environment.

[0006] In order to achieve the above technical purpose, the present invention adopts the following technical solutions:

[0007] The utility model provides a high-temperature steel coil clamp, which includes:

[0008] A support assembly comprising a base, two pliers legs corresponding to each other, and two pliers claws, wherein one end of the pliers leg is slidably mounted on the base, and the pliers claw is mounted on the other end of the pliers leg; and

[0009] Two groups of sensor components corresponding to the two jaws, the sensor components include a displacement sensor, a cable, an elastic member and a slide. The slide is slidably arranged on the jaw along the length direction of the jaw leg. One end of the elastic member is connected to the slide, and the other end is connected to the jaw. The elastic member has an elastic force that causes the slide to slide toward the base. The displacement sensor is installed at one end of the jaw leg close to the base. One end of the cable is connected to the slide, and the other end is connected to the displacement sensor.

[0010] In some embodiments, the clamp claw is provided with a mounting groove, and the slide is slidably disposed in the mounting groove.

[0011] In some embodiments, the elastic member includes a spring, which is built into the mounting slot, and one end of the spring is connected to the slide support, and the other end of the spring is connected to the clamp claw.

[0012] In some embodiments, there are multiple springs, and the multiple springs are arranged side by side.

[0013] In some embodiments, the clamp claw is provided with a guide hole, the slide has a guide rod, and the guide rod is movably provided in the guide hole.

[0014] In some embodiments, a mounting hole is provided inside the pliers leg, and the cable is built into the mounting hole.

[0015] In some embodiments, a buffer pad is provided on one side of the pliers leg where the pliers claw is mounted.

[0016] In some embodiments, the base is provided with a guide rail, the pliers legs are provided with a guide groove, and the guide groove is sleeved on the guide rail so that the pliers legs slide along the guide rail.

[0017] In some embodiments, the guide rail has a T-shaped cross section, and the guide groove has a T-shaped cross section.

[0018] In some embodiments, the displacement sensor is a drawstring sensor.

[0019] First, move the two legs so that the two claws extend into the inner ring of the steel coil. If the claws successfully extend into the inner ring of the steel coil, as the base is lifted, the inner ring of the steel coil contacts the slide and overcomes the elastic force of the elastic member, causing the slide to slide. This in turn pulls the displacement sensor via the cable. The feedback signal from the displacement sensor can then be used to determine whether the claws have successfully extended into the inner ring of the steel coil. The displacement sensor of the above-mentioned high-temperature steel coil clamp is installed at the end of the leg close to the base, so that the displacement sensor is far away from the high-temperature steel coil to prevent high temperature damage to the displacement sensor.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is 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 the present invention and are not intended to limit the present invention.

[0023] In order to solve the technical problem of how to prevent high temperature environment from damaging the sensor, the utility model provides a high temperature steel coil clamp, which moves the sensor away from the high temperature steel coil to prevent high temperature from damaging the sensor.

[0024] It should be noted that the high-temperature steel coil clamp of the present invention is used for but not limited to steel coil lifting, etc. For the convenience of explanation, in the present invention, only the application of the high-temperature steel coil clamp to steel coil lifting is used as an example for explanation. The principle of applying the high-temperature steel coil clamp to other types of equipment is essentially the same as the principle applied to steel coil lifting, so they will not be described here one by one.

[0025] See also Figure 1 , Figure 1 This is a structural schematic diagram of a high-temperature steel coil clamp in one embodiment of the present invention. The high-temperature steel coil clamp includes a support assembly 100 and two sets of sensor assemblies 200. The support assembly 100 includes a base 110, two clamp legs 120 corresponding to each other, and two clamp claws 130. One end of the clamp leg 120 is slidably set on the base 110, and the clamp claw 130 is installed on the other end of the clamp leg 120. The two groups of sensor components 200 correspond one-to-one to the two jaws 130. The sensor components 200 include a displacement sensor 210, a cable 220, an elastic member 230 and a slide 240. The slide 240 is slidably arranged on the jaw 130 along the length direction of the jaw leg 120. One end of the elastic member 230 is connected to the slide 240, and the other end is connected to the jaw 130. It has an elastic force that causes the slide 240 to slide toward the base 110. The displacement sensor 210 is installed at one end of the jaw leg 120 close to the base 110. One end of the cable 220 is connected to the slide 240, and the other end is connected to the displacement sensor 210.

[0026] In this embodiment, the two legs 120 are first moved so that the two claws 130 extend into the inner ring of the steel coil. If the claws 130 successfully extend into the inner ring of the steel coil, as the base 110 is lifted, the inner ring of the steel coil contacts the slide 240 and overcomes the elastic force of the elastic member 230, causing the slide 240 to slide, thereby pulling the displacement sensor 210 through the cable 220. The signal fed back by the displacement sensor 210 can then be used to determine whether the claws 130 have successfully extended into the inner ring of the steel coil. The displacement sensor 210 of the above-mentioned high-temperature steel coil clamp is installed at one end of the leg 120 close to the base 110, so that the displacement sensor 210 is away from the high-temperature steel coil to prevent damage to the displacement sensor 210 due to high temperature.

[0027] In some embodiments, the jaw 130 defines a mounting slot 131 , and the slide 240 is slidably disposed in the mounting slot 131 .

[0028] In this embodiment, the mounting groove 131 serves to limit and guide the slide support 240 , and the sliding direction of the slide support 240 is limited by the inner wall of the mounting groove 131 .

[0029] Based on the above embodiments, in some embodiments, the elastic member 230 includes a spring 231 . The spring 231 is built into the mounting slot 131 , and one end of the spring 231 is connected to the slide 240 , and the other end is connected to the claw 130 .

[0030] In this embodiment, when the steel coil presses against the slide 240, causing the slide 240 to slide away from the base 110, the slide 240 overcomes the elastic force of the spring 231, causing the spring 231 to accumulate elastic potential energy. When the steel coil separates from the slide 240, the spring 231 releases the elastic potential energy, further pushing the slide 240 toward the base 110 until the spring 231 returns to its initial state.

[0031] In some embodiments, there are multiple springs 231 , and the multiple springs 231 are arranged side by side.

[0032] In this embodiment, a plurality of springs 231 are arranged side by side, so that the slide 240 can be supported by the springs 231 in all directions.

[0033] In some embodiments, the jaw 130 defines a guide hole 132 , and the slide 240 includes a guide rod 241 movably inserted into the guide hole 132 .

[0034] In this embodiment, since the guide rod 241 is slidably inserted into the guide hole 132 , the slide 240 has a more precise sliding track under the guidance of the guide rod 241 .

[0035] In some embodiments, a mounting hole 121 is defined inside the caliper leg 120 , and the cable 220 is built into the mounting hole 121 .

[0036] In this embodiment, the cable 220 can be hidden inside the mounting hole 121 .

[0037] In some embodiments, a buffer pad is provided on the side of the pliers leg 120 where the pliers jaw 130 is mounted.

[0038] In this embodiment, the buffer pad can play a buffering role to prevent the clamp legs 120 from being damaged by the steel coil.

[0039] In some embodiments, the base 110 is provided with a guide rail 111 , and the pliers legs 120 are provided with guide grooves. The guide grooves are sleeved on the guide rail 111 so that the pliers legs 120 slide along the guide rail 111 .

[0040] In this embodiment, under the guidance of the guide rail 111 , the pliers leg 120 can slide relative to the base 110 .

[0041] In some embodiments, the guide rail 111 has a T-shaped cross section, and the guide groove has a T-shaped cross section.

[0042] In this embodiment, since the inner wall of the T-shaped guide groove fits the T-shaped guide rail 111 , the clamp leg 120 can be prevented from being separated from the guide rail 111 .

[0043] Any embodiment of the displacement sensor 210 is feasible as long as it can detect the movement of the cable 220. In some embodiments, the displacement sensor 210 is a cable sensor.

[0044] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail:

[0045] First, move the two legs 120 so that the two claws 130 extend into the inner ring of the steel coil. If the claws 130 successfully extend into the inner ring of the steel coil, as the base 110 is lifted, the inner ring of the steel coil contacts the slide 240 and overcomes the elastic force of the elastic member 230, causing the slide 240 to slide, thereby pulling the displacement sensor 210 through the cable 220. The signal fed back by the displacement sensor 210 can then be used to determine whether the claws 130 have successfully extended into the inner ring of the steel coil. The displacement sensor 210 of the above-mentioned high-temperature steel coil clamp is installed at one end of the leg 120 close to the base 110, so that the displacement sensor 210 is away from the high-temperature steel coil to prevent high-temperature damage to the displacement sensor 210.

[0046] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
