U-shaped beam hoisting clamp

Abstract

The utility model discloses a U-shaped beam hoisting clamp, which can stably clamp a U-shaped beam through a hinged combination of a hoisting hook and a pressing plate. First and second handles are respectively installed on the hoisting hook and the pressing plate, which not only facilitates workers to move and use the device, but also makes it very easy for a single person to use the device. When the worker clamps the U-shaped beam, the hoisting chain at the upper end of the device drives the hoisting hook and the pressing plate to move upward through the connecting plate. Under the action of gravity, the hoisting hook and the pressing plate always have a mutual clamping tendency. When the U-shaped beam is installed, it is not only fast and convenient, but also can be firmly clamped during hoisting by relying on the action of gravity. The utility model can reduce the labor resources and production cost, and can ensure the stability during transportation. When the U-shaped beam is unloaded, the worker only needs to pull the first handle to rotate the hoisting hook away from the pressing plate, so that the U-shaped beam can be separated from the hoisting clamp. The utility model can be quickly disassembled and can be operated by a single person, which greatly improves the production efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of U-beam transfer equipment, specifically a U-beam hoisting clamp. Background Technology

[0002] U-beams are used in the manufacturing process of many industries. When moving and transporting U-beams, special lifting equipment is required to place them in the designated location. Currently, before and after transportation, workers need to install the lifting equipment onto the U-beam. During the installation process, workers need to use locking bolts and other tools to fix the U-beam to the lifting fixture before it can be transported. When it is transported to the designated location, workers need to remove the bolts and other tools to detach the lifting fixture from the U-beam. This leads to reduced production efficiency, cumbersome loading and unloading steps, and great safety hazards during handling. Summary of the Invention

[0003] The purpose of this utility model is to provide a U-shaped beam lifting clamp, which consists of a lifting hook, a clamping plate, a connecting plate, and a lifting chain. This U-shaped beam lifting clamp can be installed and unloaded without manual fastening or complicated steps, thus solving the problems in the prior art.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A U-shaped beam lifting clamp includes two sets of hanging mechanisms. Each hanging mechanism has a lifting hook and a clamping plate that are hinged to each other. The lifting hook and the clamping plate are connected by a first hinge shaft. The lifting hook has a first elongated groove, and the clamping plate has a second elongated groove. A connecting plate is hinged at the intersection of the first elongated groove and the second elongated groove. A first handle is installed on the side of the lifting hook away from the clamping plate, and a second handle is installed on the side of the clamping plate away from the lifting hook. The lifting hook and the clamping plate are hinged at one end of the connecting plate, and a lifting chain is installed at the other end of the connecting plate. The lifting chain can drive the connecting plate to move together. The upward movement of the connecting plate can cause the lifting hook and the clamping plate to clamp each other. The connecting plate includes two symmetrically arranged fixing plates. Each fixing plate has through holes at both ends along its length. A second hinge shaft is installed on the corresponding through holes of the two fixing plates. A first through hole is provided on the first hinge shaft, and a second through hole is provided on the second hinge shaft at the end away from the lifting chain. A connecting rope is installed in both the first and second through holes. A movable grip is installed on the second handle. A spring is installed between the second handle and the grip, and the spring tends to move the grip closer to the pressure plate. T-shaped blocks are provided at both ends along the length of the grip. A T-shaped groove is provided on the second handle to cooperate with the T-shaped blocks. One end of the connecting rope passes through the second through hole and is installed with a limit block. The other end of the connecting rope passes through the first through hole and is connected to the grip. When the grip moves against the spring force, it can make the first hinge shaft tend to move closer to the second hinge shaft. The lifting hook has a U-shaped groove, on which a U-shaped plate is installed. The U-shaped plate includes a vertically arranged web and flanges at both ends along the height of the web. Screw holes are formed on the flanges, and a first wear-resistant pad is installed on the inner side of each flange. The first wear-resistant pad has a countersunk hole, and a fixing bolt that mates with the screw hole is installed in the countersunk hole. A square groove is formed on the clamping plate, on which a fixing seat is installed. A second wear-resistant pad is installed on the fixing seat, and a countersunk hole is formed on the second wear-resistant pad. A screw hole that mates with the countersunk hole is installed on the fixing seat, and a fixing bolt that mates with the screw hole is installed in the countersunk hole. The lifting chains of the two sets of hanging mechanisms are installed at both ends along the length of the rectangular tube. A wire rope is installed on the side of the rectangular tube away from the lifting chain, and the wire rope mates with the lifting hook.

[0005] The positive effects of this utility model are as follows: The U-shaped beam lifting clamp described in this utility model can stably clamp the U-shaped beam through the hinged combination of the lifting hook and the clamping plate. A first handle and a second handle are respectively installed on the lifting hook and the clamping plate, which not only facilitates the movement and use of the device by workers, but also makes it very easy for a single person to use. When the worker clamps the U-shaped beam, the lifting chain at the upper end of the device drives the lifting hook and the clamping plate to move upward through the connecting plate. Under the action of gravity, the lifting hook and the clamping plate always tend to clamp each other. The installation is not only quick and convenient, but also can be firmly clamped by gravity during the lifting process. While reducing manpower and production costs, it can also ensure stability during transportation. When unloading the U-shaped beam, simply pull the first handle to rotate the lifting hook away from the clamping plate, and the U-shaped beam can be released from the lifting clamp. It can not only be disassembled quickly, but also can be operated by a single person, greatly improving production efficiency. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these examples. Any improvements made without departing from the spirit of the present invention shall fall within the protection scope of the present invention.

[0018] like Figure 1 As shown, the U-shaped beam hoisting fixture of this utility model includes two sets of hanging mechanisms. Each hanging mechanism has a hoisting hook 1 and a clamping plate 2 that are hinged to each other. The U-shaped beam is hung by the hoisting hook 1 and the clamping plate 2 thereby limiting the movement of the U-shaped beam. This reduces the number of hanging steps and improves production efficiency. The hoisting hook 1 and the clamping plate 2 are connected by a first hinge shaft 3.

[0019] The lifting hook 1 has a first elongated groove 4, and the clamping plate 2 has a second elongated groove 5. A connecting plate 6 is hinged at the junction of the first elongated groove 4 and the second elongated groove 5. A first handle 7 is installed on the side of the lifting hook 1 away from the clamping plate 2, and a second handle 8 is installed on the side of the clamping plate 2 away from the lifting hook 1. The opening and closing of the lifting hook 1 and the clamping plate 2 can be manually controlled by the first handle 7 and the second handle 8.

[0020] One end of the connecting plate 6 is hinged to the lifting hook 1 and the clamping plate 2, and the other end of the connecting plate 6 is equipped with a lifting chain 9. The lifting hook 1, the clamping plate 2, and the lifting chain 9 are all connected to the connecting plate 6 through the second hinge shaft 12. The lifting chain 9 can drive the connecting plate 6 to move together. The upward movement of the connecting plate 6 can cause the lifting hook 1 and the clamping plate 2 to clamp each other. Traditional lifting mechanisms require bolts or other auxiliary locking to fix the U-shaped beam. This device only requires pulling the first handle 7 to hang the lifting hook 1 on the wing plate of the U-shaped beam. The lifting chain 9 drives the device to move upward, and the U-shaped beam can be firmly fixed in the lifting fixture by gravity. When disassembling, only the first handle 7 needs to be pulled to separate the lifting hook 1 from the wing plate of the U-shaped beam. The steps are simple and the installation is more convenient.

[0021] Furthermore, in actual operation, if the worker stands near the first handle 7, they can pull the first handle 7 to separate the lifting hook 1 from the U-shaped beam flange, thus completing the disassembly. However, if the worker is near the clamping plate 2 while disassembling the U-shaped beam, they need to step over the U-shaped beam or go around to the opposite side to continue pulling the first handle 7 to rotate the lifting hook 1 and remove the U-shaped beam. This reduces the worker's disassembly efficiency and poses a significant safety hazard when stepping over the U-shaped beam. To solve these problems, this new structure is added to the device to make it easier and faster for workers to disassemble and assemble the U-shaped beam. The connecting plate 6 may include fixed plates 10 symmetrically arranged on both sides, each fixed plate 10 having a length... Both ends of the first hinge 3 have through holes 11. The two fixed plates 10 are equipped with second hinge shafts 12 on the corresponding through holes 11. The fixed plates 10 are fixedly installed on both sides of the second hinge shafts 12. The first hinge shaft 3 has a first through hole 13. The second hinge shaft 12, which is away from the end of the lifting chain 9, has a second through hole 14. Both the first through hole 13 and the second through hole 14 are equipped with connecting ropes 15. The second handle 8 is equipped with a movable grip 16. A spring 17 is installed between the second handle 8 and the grip 16. The spring 17 tends to bring the grip 16 closer to the pressure plate 2. The grip 16 has T-shaped blocks 18 at both ends in the length direction. The second handle 8 has T-shaped grooves 19 that cooperate with the T-shaped blocks 18.

[0022] Guided by the T-shaped block 18 and the T-shaped groove 19, the grip 16 can only move along the height direction of the second handle 8. One end of the connecting rope 15 passes through the second through hole 14 and is fitted with a limiting block 20. The limiting block 20 limits the movement of the connecting rope 15, ensuring that the connecting rope 15 is always connected to the second hinge shaft 12 during traction. The other end of the connecting rope 15 passes through the first through hole 13 and is connected to the grip 16. When the grip 16 moves against the elastic force of the spring 17, it can cause the first hinge shaft 3 to tend to move closer to the second hinge shaft 12. While pulling the second handle 8, gripping the grip 16 overcomes the elastic force of the spring 17 and drives the connecting rope 15 to move. Through the limiting effect of the limiting block 20 on the connecting rope 15, the first hinge shaft 3 is pulled closer to the second hinge shaft 12 by the connecting rope 15. This causes the first handle 7 to rotate together when the second handle 8 is pulled, and the lifting hook 1 and the clamping plate 2 rotate and separate, allowing the U-shaped beam to be hung or unloaded.

[0023] Furthermore, the lifting hook 1 is provided with a U-shaped groove 21, and a U-shaped plate 22 is installed on the U-shaped groove 21. The U-shaped plate 22 is fixedly installed with the U-shaped groove 21. The U-shaped plate 22 includes a vertically arranged web plate 23 and wing plates 24 at both ends of the web plate 23 in the height direction. The wing plates 24 are provided with screw holes. A first wear-resistant pad 25 is installed on the inner side of the wing plate 24. During the process of supporting the U-shaped beam, the first wear-resistant pad 25 increases the friction to ensure stable support, while also protecting the U-shaped plate 22 from scratching the U-shaped beam and protecting the surface integrity of the U-shaped beam. The first wear-resistant pad 25 is provided with a countersunk hole, and a fixing bolt that matches the screw hole is installed in the countersunk hole. When the fixing bolt is installed in the countersunk hole, the first wear-resistant pad 25 can be fixed to the wing plate 24, and the fixing bolt hidden in the countersunk hole will not damage the U-shaped beam.

[0024] Furthermore, a square groove 27 is provided on the clamping plate 2, and a fixing seat 28 is installed on the square groove 27. The fixing seat 28 is also fixedly installed on the square groove 27. A second wear-resistant pad 26 is installed on the fixing seat 28. The second wear-resistant pad 26 has a countersunk hole. A screw hole that matches the countersunk hole is provided on the fixing seat 28. A fixing bolt that matches the screw hole is installed in the countersunk hole.

[0025] Furthermore, the lifting chains 9 of the two sets of hanging mechanisms are installed at both ends of the length of the square tube 29. A wire rope is installed on the side of the square tube away from the lifting chain 9. The wire rope cooperates with the hook. The square tube 29 connected by the wire rope ensures that the whole is in a horizontal state during the lifting, and together drive the two sets of hanging mechanisms to move, ensuring stability and safety during transportation.

[0026] When moving this device to the U-shaped beam hoisting location using large lifting equipment, before transportation, the operator needs to pull the first handle 7 to rotate the lifting hook 1 away from the clamping plate 2 and move it closer to the U-shaped beam. The lifting hook 1 is then hooked onto the flange of the U-shaped beam. Subsequently, the first handle 7 is released so that the clamping plate 2 fits against the web of the U-shaped beam, clamping the U-shaped beam. The lifting equipment is then started, and the steel wire rope drives the rectangular tube 29 to ensure that it remains horizontal during hoisting. The lifting chain 9 connected to the rectangular tube 29 drives the device upward. At the same time, under the action of gravity, the lifting hook 1 and the clamping plate 2 can press against each other, so that the U-shaped beam can be stably fixed between the lifting hook 1 and the clamping plate 2. When unloading at the designated location, if the worker pulls the first handle 7, the lifting hook 1 will rotate away from the clamping plate 2, and the U-shaped beam can then detach from the hanging mechanism to complete the unloading. If, after transportation, the worker disassembles the clamping plate 2 on one side, pulling the second handle 8 will simultaneously move the lever 16 against the spring force of the spring 17 towards the second handle 8. As the lever 16 moves, it will pull the connecting rope 15, causing the first hinge shaft 3 to move closer to the second hinge shaft 12. At this time, the lifting hook 1 and the clamping plate 2 will move away from each other. Figure 10As shown, the lifting hook 1 and the clamping plate 2 form an open space, allowing the U-shaped beam to be removed from the restricted area of ​​the lifting hook and the clamping plate. Then, the entire equipment is moved away from the U-shaped beam to complete the unloading.
