In addition, in order to be clear and concise, the description of known functions and structures is omitted.
[0025] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.
[0026] In the prior art, the PVC foamed board needs to be hoisted and transported during production and assembly, but there is currently a lack of special lifting appliance for hoisting the PVC foamed board, so that the crane is not convenient when hoisting the PVC foamed board. Therefore, the present application provides a hoisting and clamping device, which can conveniently hoist and transport the foamed board and is not easy to fall off during hoisting.
[0027] The embodiment of the present application provides a hoisting and clamping device for a foamed piece, which can conveniently hoist and transfer the foamed plate and is not easy to fall off during hoisting. The hoisting and clamping device comprises a clamping assembly, a first connecting piece and a second connecting piece. The clamping assembly has a first clamping arm and a second clamping arm at the front end and a first operating arm and a second operating arm at the rear end; wherein the first operating arm and the second operating arm are used for controlling the first clamping arm and the second clamping arm to act; a clamping opening for placing the product is formed between the first clamping arm and the second clamping arm; a sharp cone capable of piercing the product is arranged on the first clamping arm, the sharp cone is located in the clamping opening and points to the second clamping arm; when the first operating arm and the second operating arm are close to each other, the first clamping arm and the second clamping arm are close to each other to clamp the product located between the first clamping arm and the second clamping arm and the sharp cone pierces the product; the first connecting piece is used for suspending the first operating arm to the lifting tool of the crane, and the second connecting piece is used for suspending the second operating arm to the lifting tool of the crane.
[0028] In work, the hoisting and clamping device is installed on the crane and is used for hanging the foamed plate to the lifting hook of the crane. The hoisting and clamping device comprises a clamping assembly, a first connecting piece and a second connecting piece, the clamping assembly is essentially a pincer type clamping tool, and the first clamping arm and the second clamping arm can be controlled by the first operating arm and the second operating arm to clamp the object. When the foamed plate is clamped by using the clamping assembly, the foamed plate is first placed into the clamping opening between the first clamping arm and the second clamping arm, then the first operating arm and the second operating arm are operated to be close to each other, so that the first clamping arm and the second clamping arm are close to each other to clamp the foamed plate located between the first clamping arm and the second clamping arm, and at the same time, the sharp cone on the first clamping arm pierces the product. When the clamping assembly needs to release the foamed plate, the first operating arm and the second operating arm are operated to be away from each other, so that the first clamping arm and the second clamping arm are away from each other to release the foamed plate located between the first clamping arm and the second clamping arm.
[0029] In a specific scheme, the crane can be a trolley, and the lifting tool is a lifting hook. The first connecting piece and the second connecting piece respectively suspend the first operating arm and the second operating arm to the lifting hook of the trolley, after the clamping assembly clamps the foamed plate, the trolley can hoist and transfer the foamed plate, and because the sharp cone pierces the foamed plate, the foamed plate is not easy to fall off during hoisting.
[0030] Reference Figures 1-3In an embodiment of the present application, the hoisting and clamping device comprises a clamping assembly 10, a first connecting member 20a and a second connecting member 20b. The clamping assembly 10 has a first clamping arm 11 and a second clamping arm 12 at the front end, and a first operating arm 13 and a second operating arm 14 at the rear end. The first operating arm 13 and the second operating arm 14 are used to control the actions of the first clamping arm 11 and the second clamping arm 12. The first clamping arm 11 and the second clamping arm 12 form a clamping opening for placing the foam board 40 therebetween. The first clamping arm 11 is provided with a pointed cone 18 capable of piercing the foam board 40, and the pointed cone 18 is located in the clamping opening and points to the second clamping arm 12. When the first operating arm 13 and the second operating arm 14 are close to each other, the first clamping arm 11 and the second clamping arm 12 are close to each other to clamp the foam board 40 therebetween, and the pointed cone 18 pierces the foam board 40. The first connecting member 20a is used to suspend the first operating arm 13 to the spreader of the crane, and the second connecting member 20b is used to suspend the second operating arm 14 to the spreader of the crane.
[0031] In an optional embodiment, the clamping assembly 10 adopts a vice structure. The jaws of the vice can lock and generate a large clamping force, so that the clamped parts will not be loosened. Further, the first clamping arm 11 is fixed to the first operating arm 13, and the second clamping arm 12 is hingedly connected to the first operating arm 13 and the second operating arm 14, respectively. An active arm 15 is further arranged between the first operating arm 13 and the second operating arm 14. The first end of the active arm 15 is hingedly connected to the second operating arm 14, and the second end of the active arm 15 is movably arranged in the first operating arm 13. The end of the first operating arm 13 is further provided with an adjusting bolt 16 for adjusting the position of the second end of the active arm 15. The second clamping arm 12 and the first operating arm 13 are connected by a tension spring 17. In some technical solutions, the clamping assembly 10 is further provided with an unlocking handle. It should be understood that the specific description of the vice structure can be referred to the prior art, which will not be repeated here.
[0032] In use of the clamping assembly 10 to clamp the foamed plate 40, first, the foamed plate 40 is placed into the clamping opening between the first clamping arm 11 and the second clamping arm 12, then the first operating arm 13 and the second operating arm 14 are operated to move close to each other, so that the first clamping arm 11 and the second clamping arm 12 move close to each other to clamp the foamed plate 40 therebetween, at the same time, the sharp cone 18 on the first clamping arm 11 pierces the foamed plate 40. When the clamping assembly 10 needs to release the foamed plate 40, the first operating arm 13 and the second operating arm 14 are operated to move away from each other, so that the first clamping arm 11 and the second clamping arm 12 move away from each other to release the foamed plate 40 therebetween. The first connecting member 20a and the second connecting member 20b respectively suspend the first operating arm 13 and the second operating arm 14 to the hook 30 of the crane, after the clamping assembly 10 clamps the foamed plate 40, the crane can hoist and transfer the foamed plate 40, and since the sharp cone 18 pierces the foamed plate, the foamed plate is not easy to fall off during hoisting.
[0033] Reference Figure 1 and Figure 2 In the present embodiment, the first connecting member 20a and the second connecting member 20b are both closed connecting members; the first operating arm 13 is provided with a first annular portion 131, the first connecting member 20a passes through the inner ring of the first annular portion 131 and is hung to the hook 30 of the crane; the second operating arm 14 is provided with a second annular portion 141, the second connecting member 20b passes through the inner ring of the second annular portion 141 and is hung to the hook 30 of the crane. During hoisting, the first connecting member 20a respectively passes through the inner ring of the first annular portion 131 and the hook 30, and the second connecting member 20b respectively passes through the inner ring of the second annular portion 141 and the hook 30.
[0034] In an alternative embodiment, the first connecting member 20a and the second connecting member 20b are in the form of a rope, specifically a steel wire rope.
[0035] Reference Figure 4In an alternative embodiment, the closed connecting component is composed of the main structural member 21 and the opening and closing member 22, which is rotatably connected to the main structural member 21; the opening and closing member 22 can be rotated to an open position or a closed position; when the opening and closing member 22 is in the closed position, the main structural member 21 and the opening and closing member 22 jointly form a closed connecting structure; the opening and closing member 22 is defined to be rotated to the open position inwards. Specifically, the first connecting member 20a includes the main structural member 21 and the opening and closing member 22, which jointly form a closed connecting structure when hoisting and loading, and respectively pass through the inner ring of the first annular portion 131 and the hook 30. The second connecting member 20b includes the main structural member 21 and the opening and closing member 22, which jointly form a closed connecting structure when hoisting and loading, and respectively pass through the inner ring of the second annular portion 141 and the hook 30. In addition, it should be noted that the opening and closing member 22 is defined to be rotated to the open position inwards, which is safer during hoisting.
[0036] Further, the main structural member 21 and the opening and closing member 22 are further provided with an elastic member, which is used to elastically drive the opening and closing member 22 to remain in the closed position. When hoisting and loading, the opening and closing member 22 remains in the closed position under the action of the elastic member, and the clamping assembly 10 is reliably hung on the hook. When disassembly is needed, the opening and closing member 22 can be pushed to rotate to the open position inwards against the elastic force of the spring.
[0037] Further, the second clamping arm 12 is provided with a containing groove 19, which corresponds to the position of the sharp cone 18 and can contain the sharp cone 18 when the first operating arm 13 and the second operating arm 14 are close to each other. In this structure, when the clamping assembly 10 clamps the foamed board, the first operating arm 13 and the second operating arm 14 are close to each other, and the sharp cone 18 on the first clamping arm 11 pierces the foamed board 40 and enters the containing groove 19 on the second operating arm 14.
[0038] The embodiment of the present application also provides a hoisting device, which includes a crane and the hoisting and clamping device for foamed pieces provided in the foregoing.
[0039] In operation, the lifting and clamping device is mounted on a crane and used to hang the foam board on the lifting hook of the crane. The lifting and clamping device comprises a clamping assembly, a first connecting member and a second connecting member. The clamping assembly is essentially a pincer type clamping tool. The first clamping arm and the second clamping arm can be controlled by means of the first operating arm and the second operating arm. In use, the foam board is first placed in the clamping opening between the first clamping arm and the second clamping arm. Then, the first operating arm and the second operating arm are operated to move closer to each other so that the first clamping arm and the second clamping arm move closer to each other to clamp the foam board therebetween. At the same time, the sharp point on the first clamping arm pierces the product. When the clamping assembly needs to release the foam board, the first operating arm and the second operating arm are operated to move away from each other so that the first clamping arm and the second clamping arm move away from each other to release the foam board therebetween. In a specific embodiment, the crane can be a trolley, and the lifting tool is a lifting hook. The first connecting member and the second connecting member respectively suspend the first operating arm and the second operating arm to the lifting hook of the trolley. After the clamping assembly clamps the foam board, the trolley can hoist and transfer the foam board. Since the sharp point pierces the foam board, the foam board is not easy to fall off during hoisting.
