It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0032] like Figures 1 to 3 As shown, a disclosed lifting pad block in an embodiment of the present application includes: a pad block 10 and a limiting portion 20, the pad block 10 includes a first contact surface 11, a second contact surface 12 and a third contact surface 13, the angle between the first contact surface 11 and the second contact surface 12 is consistent with the angle of the workpiece to be lifted, the third contact surface 13 is connected to the first contact surface 11, the third contact surface 13 is connected to the second contact surface 12, the third contact surface 13 is an arc-shaped surface, the limiting portion 20 is connected to both ends of the pad block 10, and in the length direction, the projection area of ​​the limiting portion 20 is larger than the projection area of ​​the pad block 10.

[0033] The technical solution of the first embodiment is applied, and a cushion block 10 is arranged at the corner of the workpiece to be hoisted, so that the first contact surface 11 and the second contact surface 12 are both in contact with the surface of the workpiece, and the sling is arranged in close contact with the third contact surface 13. The setting of the limiter 20 ensures that the sling is always in contact with the arc surface and is not easy to be separated. Since the third contact surface 13 is an arc surface, the sling is not easy to be worn and broken. The technical solution of the first embodiment effectively solves the problem of the sling being worn and broken by the corners of the workpiece during the hoisting of large-sized workpieces in the prior art, resulting in the fall of the workpiece.

[0034] like Figure 3 As shown, in the technical solution of the first embodiment, the cushion block 10 further includes a groove 14, the first edge of the groove 14 is connected to the first contact surface 11, and the second edge of the groove 14 is connected to the second contact surface 12. The arrangement of the groove 14 makes it possible for the edges of the cushion block to not contact the cushion block 10 when the cushion block 10 is fixed to the workpiece to be hoisted, thereby avoiding the collision between the hoisted workpiece and the cushion block 10 due to vibration, resulting in deformation and fracture of the workpiece edges and corners, and affecting the quality of the workpiece. The groove 14 can be in various shapes such as round and square, as long as it avoids the edges and corners of the workpiece.

[0035] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the cushion block 10 includes a first adsorption section 15, a second adsorption section 16 and a connecting section 17, the first contact surface 11 is arranged on the first adsorption section 15, the second contact surface 12 is arranged on the second adsorption section 16, the first adsorption section 15, the second adsorption section 16 and the connecting section 17 are connected in sequence, and the first adsorption section 15, the second adsorption section 16 and the connecting section 17 together form an arc surface and a groove 14. The first adsorption section 15 is adsorbed on the first side of the workpiece to be hoisted, at which time the first contact surface 11 is arranged in contact with the first side, and the second adsorption section 16 is adsorbed on the second side of the workpiece to be hoisted, at which time the second contact surface 12 is arranged in contact with the second side, and the arrangement of the first adsorption section 15 and the second adsorption section 16 avoids relative movement between the cushion block 10 and the workpiece to be hoisted, which causes the workpiece to fall off.

[0036] like Figures 1 to 3As shown, in the technical solution of the first embodiment, the first adsorption section 15 includes a first accommodating portion 151, the second adsorption section 16 includes a second accommodating portion 161, the connecting section 17 includes a third accommodating portion 171, the first accommodating portion 151, the second accommodating portion 161 and the third accommodating portion 171 together constitute an accommodating cavity, the cushion block 10 also includes a first magnet 18, a second magnet and a rotary switch 19, the first magnet 18 is arranged in the accommodating cavity, the second magnet is connected to the rotary switch 19, and the rotary switch 19 is rotatably arranged in the accommodating cavity. The N pole and the S pole of the first magnet 18 respectively abut against the inner wall of the first adsorption section 15 and the inner wall of the second adsorption section 16, and the rotary switch 19 is rotated, and the second magnet rotates inside the accommodating cavity with the rotary switch 19. When the N pole of the second magnet abuts against the first adsorption section 15 and the S pole of the second magnet abuts against the second adsorption section 16, the magnetic field formed by the first magnet 18 and the second magnet is partially distributed outside the cushion block 10, and the workpiece to be hoisted with magnetic conductivity is fitted with the cushion block 10 under the action of magnetic force; when the N pole of the second magnet abuts against the second adsorption section 16 and the S pole of the second magnet abuts against the first adsorption section 15, the magnetic field formed by the first magnet 18 and the second magnet is closed inside the cushion block 10, there is no magnetic field outside the cushion block 10, and the workpiece will not be affected by the magnetic field force. By turning the rotary switch 19 to change the magnetic field distribution, the magnitude of the magnetic field force can be controlled, which is convenient for installing and removing the cushion block 10.

[0037] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the limit part 20 includes a through hole, which is arranged corresponding to the accommodating cavity, and the rotary switch 19 is partially penetrated in the through hole. The rotary switch 19 is partially arranged outside the through hole and located on the side of the limit part 20 away from the cushion block 10. The rotary switch 19 is provided with a protrusion, and the setting of the protrusion facilitates the staff to operate the rotary switch 19.

[0038] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the first adsorption section 15 and the second adsorption section 16 are made of magnetic conductive material, and the connecting section 17 is made of non-magnetic conductive material. The first adsorption section 15 and the second adsorption section 16 are made of magnetic conductive material to achieve magnetic field distribution, forming a closed circuit between the two, and the workpiece is not affected by magnetic force.

[0039] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the first adsorption section 15 and the second adsorption section 16 are made of 65# manganese steel. 65# manganese steel not only meets the magnetic condition, but also has a certain compressive strength, is not easy to deform and damage when carrying heavy workpieces, and has a long service life.

[0040] like Figure 4As shown, the difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the first adsorption section 15 includes a plurality of first adsorption holes 152, the second adsorption section 16 includes a plurality of second adsorption holes 162, the connecting section 17 includes an air circuit, and the plurality of first adsorption holes 152 and the plurality of second adsorption holes 162 are all connected to the air circuit. The air circuit is connected by a vacuum pump to provide a negative pressure environment in the air circuit, the first adsorption holes 152 and the second adsorption holes 162, and the workpiece and the cushion block 10 are fixed together by vacuum adsorption. The technical solution of the second embodiment does not require the workpiece itself to be magnetic, so the lifting cushion block provided in the second embodiment meets more usage requirements and has stronger versatility.

[0041] like Figure 4 As shown, in the technical solution of the second embodiment, the first adsorption section 15, the second adsorption section 16 and the connecting section 17 are an integrally formed structure. The hoisting pad block made of the integrally formed structure has high strength, is not easy to deform, and has a longer service life.

[0042] According to another aspect of the present application, a lifting device is provided, the lifting device adopts the above-mentioned lifting pad, and the lifting device includes a lifting belt, the lifting belt is partially arranged in contact with the third contact surface 13, and is located between the two limiting portions 20. Since the third contact surface is an arc surface, it is not easy for the lifting belt to break due to large local pressure, and the setting of the two limiting portions 20 avoids the problem that the lifting belt moves along the axial direction of the third contact surface 13, causing the lifting belt to separate from the third contact surface 13 and the workpiece to fall.

[0043] Based on the above, it can be known that the main body of the No. 65 manganese steel pad (lifting pad) is placed at the lifting acute angle position, and then the switch of the V-shaped magnetic base is turned on to make the main body firmly adsorbed, and the lifting belt or wire rope is placed in the groove of the No. 65 manganese steel pad main body (between the two limit parts 20). The tool (lifting pad) uses the angle wrapping method to change the original acute angle into an obtuse angle, which greatly protects the lifting belt and wire rope. The tool is equipped with a V-shaped switch-type magnetic base that can be well adsorbed on the hoisting object. When the tool is hoisting materials that cannot be magnetized, the V-shaped switch-type magnetic base can be replaced with a hand pump suction cup. The tool is simple to operate, safe and fast.

[0044] So far, the embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution of the present application.

[0045] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
