Description

Technical Field

[0001] The utility model relates to the field of lifting clamps, in particular to a floating protection clamp. Background Art

[0002] Crane clamps are primarily used to grasp heavy objects vertically within a certain range. There are many types of crane clamps, with horizontal electric clamps being the most commonly used for crane applications. They are primarily used in metallurgical industries such as slab continuous casting, hot rolling, and cold rolling.

[0003] As can be seen in patent application number CN200720100413.2, after the clamps grasp the material, the material slides downward relative to the jaws under the action of gravity until it is supported by the protrusions at the bottom of the jaws. During this sliding process, the jaws can easily scratch the surface of the material.

[0004] Therefore, how to prevent the material from being scratched when the material slides relative to the clamp claws is a technical problem that needs to be solved urgently. Utility Model Content

[0005] The purpose of the utility model is to overcome the above technical deficiencies and to provide a floating protection clamp to solve the technical problem in the prior art of how to prevent the material from being scratched when the material slides relative to the clamp claws.

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

[0007] The utility model provides a floating protection clamp, which includes:

[0008] base;

[0009] Two oppositely disposed jaws, the jaws being movably disposed on the base and capable of relative movement; and

[0010] Two groups of floating components corresponding to the two jaws are provided, and the floating components include a slide and an adjusting member. The slide is slidably arranged on the inner side of the jaws, and the slide has a first position close to the base and a second position away from the base. The adjusting member is transmission-connected to the slide, and the adjusting member has a first state for driving the slide to slide toward the first position, and a second state for allowing the slide to slide toward the second position.

[0011] In some embodiments, the adjustment member includes a counterweight, a first guide wheel, a second guide wheel and a cable. The first guide wheel and the second guide wheel are both rotatably mounted on the jaws. The cable is tensioned around the first guide wheel and the second guide wheel. The counterweight is connected to one side of the cable, and the slide is connected to the other side of the cable. When the adjustment member is in the first state, the counterweight drives the slide to slide to the first position through the cable under the action of gravity. When the adjustment member is in the second state, the material drives the slide to move so that the slide slides to the second position.

[0012] In some embodiments, the clamp claw is provided with a receiving groove, and the first guide wheel and the second guide wheel are both rotatably embedded in the receiving groove.

[0013] In some embodiments, the slide has a supporting platform, and the supporting platform prevents the slide from being completely embedded in the receiving groove.

[0014] In some embodiments, the surface of the supporting platform has anti-slip grooves.

[0015] In some embodiments, the adjusting member includes an elastic portion, two ends of the elastic portion are respectively connected to the slide and the clamp claw, and the elastic portion has an elastic force that causes the slide to slide toward the first position.

[0016] In some embodiments, the elastic portion includes a spring, and two ends of the spring are connected to the slide and the clamp claw.

[0017] In some embodiments, the base is provided with a guide groove, and the clamp claw is slidably embedded in the guide groove.

[0018] In some embodiments, the end of the clamping claw away from the base has a limiting portion, and the limiting portion is used to prevent the material from escaping from the clamping claw.

[0019] In some embodiments, the limiting portion is provided with a buffer pad.

[0020] The material is first gripped by two relatively moving jaws until the slide presses against it. As the material, under the influence of gravity, moves relative to the jaws, the slide moves synchronously with the material, moving from the first position to the second. Once the jaws release the material, the slide, under the action of an adjustment member, moves from the second position back to the first position, ready to grip another piece of material. When the floating protection clamp is gripping, the slide pressing against the material moves synchronously with the material, preventing it from slipping against the jaws and potentially scratching it.

DETAILED DESCRIPTION

[0024] 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.

[0025] In order to solve the technical problem of how to prevent the material from being scratched when the material slides relative to the clamp claw, the utility model provides a floating protection clamp, which can protect the material from being scratched when the material slides relative to the clamp claw.

[0026] It should be noted that the floating protection clamp described in the present invention is used for but not limited to lifting clamps, etc. For the convenience of explanation, in the present invention, only the floating protection clamp applied to XX equipment is used as an example for explanation. The principle of applying the floating protection clamp to other types of equipment is essentially the same as the principle applied to the lifting clamp, so they will not be described here one by one.

[0027] See also Figure 1 , Figure 1 This is a schematic structural diagram of a floating protection clamp according to an embodiment of the present invention. The floating protection clamp includes a base 100, two jaws 200, and two sets of floating assemblies 300. The two jaws 200 are arranged opposite each other, and the jaws 200 are movably arranged on the base 100, and the two jaws 200 can move relative to each other. The two sets of floating assemblies 300 correspond one-to-one with the two jaws 200. The floating assembly 300 includes a slide 310 and an adjustment member 320. The slide 310 is slidably arranged inside the jaws 200. The slide 310 has a first position close to the base 100 and a second position away from the base 100. The adjustment member 320 is transmission-connected to the slide 310 and has a first state in which the slide 310 is driven to slide toward the first position, and a second state in which the slide 310 is allowed to slide toward the second position.

[0028] First, the material is gripped by two relatively moving jaws 200 until the slide 310 presses against the material. As the material, under the action of gravity, moves relative to the jaws 200, the slide 310 moves synchronously with the material, moving from the first position to the second position. Once the jaws 200 are free from the material, the slide 310, under the action of the adjustment member 320, moves from the second position back to the first position, ready to grip another material. When the floating protection clamp is gripping material, the slide 310, pressing against the material, slides synchronously with the material, preventing it from slipping relative to the jaws 200 and potentially scratching it.

[0029] In some embodiments, the adjustment member 320 includes a counterweight 321, a first guide wheel 322, a second guide wheel 323 and a cable 324. The first guide wheel 322 and the second guide wheel 323 can be rotatably installed on the clamp jaw 200. The cable 324 is tensioned around the first guide wheel 322 and the second guide wheel 323. The counterweight 321 is connected to one side of the cable 324, and the slide 310 is connected to the other side of the cable 324. When the adjustment member 320 is in the first state, the counterweight 321 drives the slide 310 to slide to the first position through the cable 324 under the action of gravity. When the adjustment member 320 is in the second state, the material drives the slide 310 to move so that the slide 310 slides to the second position.

[0030] In this embodiment, because the counterweight 321 and the slide 310 are located on either side of the cable 324, when the slide 310 is not in contact with the material, the counterweight 321 drives the slide 310 toward the first position under the action of gravity. When the slide 310 contacts the material, the slide 310 moves with it, and is then driven by the material until the slide 310 moves to the second position.

[0031] In some embodiments, the jaw 200 defines a receiving slot 210 , and the first guide wheel 322 and the second guide wheel 323 are both rotatably embedded in the receiving slot 210 .

[0032] In this embodiment, the first guide wheel 322 and the second guide wheel 323 can be prevented from protruding from the jaw 200 .

[0033] In some embodiments, the slide 310 has a supporting platform 311 , which prevents the slide 310 from being completely embedded in the receiving slot 210 .

[0034] In this embodiment, the supporting platform 311 can prevent the slide 310 from being completely embedded in the receiving groove 210 under the limiting effect of the supporting platform 311, so that the supporting platform 311 can always protrude from the receiving groove 210, ensuring that the supporting platform 311 can contact the material.

[0035] Based on the above embodiments, in some embodiments, the surface of the supporting platform 311 has anti-slip grooves.

[0036] In this embodiment, the anti-slip grooves can increase the friction coefficient between the supporting platform 311 and the material, thereby preventing the material from sliding relative to the supporting platform 311.

[0037] In some embodiments, the adjustment member 320 includes an elastic portion 325 , with two ends of the elastic portion 325 respectively connected to the slide 310 and the claw 200 . The elastic portion 325 has an elastic force that causes the slide 310 to slide toward the first position.

[0038] In this embodiment, because the elastic portion 325 has an elastic force that causes the slide 310 to slide toward the first position, when the slide 310 is separated from the material, the elastic portion 325 pushes the slide 310 toward the first position. When the slide 310 contacts the material, the material drives the slide 310 to overcome the elastic force of the elastic portion 325 and move the slide 310 toward the second position.

[0039] Any implementation that can push the slide 310 to slide toward the first position is feasible. In some embodiments, the elastic portion 325 includes a spring 3251 , and both ends of the spring 3251 are connected to the slide 310 and the clamp claw 200 .

[0040] In some embodiments, the base 100 defines a guide groove 110 , and the jaws 200 are slidably embedded in the guide groove 110 .

[0041] In this embodiment, under the guidance of the guide groove 110 , the jaw 200 can slide relative to the base 100 along an accurate sliding trajectory.

[0042] In some embodiments, an end of the jaw 200 away from the base 100 has a limiting portion 220 , and the limiting portion 220 is used to prevent materials from escaping from the jaw 200 .

[0043] In this embodiment, the limiting portion 220 engages with the lower edge of the material, thereby preventing the material from escaping from the clamping claw 200 .

[0044] In some embodiments, a buffer pad 230 is provided on the limiting portion 220 .

[0045] In this embodiment, the buffer pad 230 can play a buffering role to prevent the limiting portion 220 from damaging the material.

[0046] In order to better understand the present invention, the following Figures 1 to 2 The technical solution of the utility model is described in detail:

[0047] First, the material is gripped by two relatively moving jaws 200 until the slide 310 presses against the material. As the material, under the action of gravity, moves relative to the jaws 200, the slide 310 moves synchronously with the material, moving from the first position to the second position. Once the jaws 200 are free from the material, the slide 310, under the action of the adjustment member 320, moves from the second position back to the first position, ready to grip another material. When the floating protection clamp is gripping material, the slide 310, pressing against the material, slides synchronously with the material, preventing it from slipping relative to the jaws 200 and potentially scratching it.

[0048] 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.
