Technical Field

[0001] This invention relates to the field of lifting clamp equipment technology, specifically a large forging vertical lifting clamp equipment. Background Technology

[0002] Lifting refers to the general term for the installation and positioning of equipment using cranes or hoisting mechanisms. Lifting generally requires the use of lifting equipment, which is manufactured by professional manufacturers. Websites that introduce lifting techniques, especially those using crane lifting technology, such as Crane Lifting Technology Home, are popular resources for this purpose.

[0003] The patent publication number CN216687084U discloses a hoisting device for large forgings, including a tubular connector, a connecting ring, and a hook position adjustment mechanism. At least four pull rings are evenly welded around the top of the connecting ring. The tubular connector includes a connector body and pull holes equidistantly opened on the inner surface of the connector body. The number of pull holes is at least four. Pull rings are fixedly connected to the pull holes by steel cables. A lifting ring is welded to the top of the connector body.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 This large forging stand-up clamp equipment offers two technical solutions:

[0029] The first embodiment includes a support plate 1, and a hook plate 2 is fixedly connected to the inner side of the support plate 1 by multiple L-shaped connecting rods. An adjustable hoisting mechanism is provided on the support plate 1. The hoisting mechanism includes an adjustment component 3, multiple clamping arm components 5 and multiple hook components 6.

[0030] The adjustment assembly 3 includes multiple sliding grooves 31 equidistantly formed in the support plate 1 along the circumference. Slider 32 is slidably connected to the inner surface of each sliding groove 31. An installation assembly 4 is provided inside the slider 32, and the installation assembly 4 is used to install the clamping arm assembly 5 or the hook assembly 6. A guide rod 33 is fixedly connected to the top of the slider 32. An adjustment plate 34 is rotatably connected to the top of the support plate 1. Multiple guide grooves 35 are equidistantly formed in the circumference of the interior of the adjustment plate 34, and the multiple guide rods 33 are respectively located inside the corresponding guide grooves 35. The adjustment assembly 3 also includes a drive motor 37. A drive gear 38 is fixedly connected to the output end of the drive motor 37. Multiple gear teeth 36 are fixedly connected at equal intervals on the inner surface of the adjustment plate 34, and the multiple gear teeth 36 mesh with the drive gear 38 for transmission.

[0031] When hoisting large forgings using the six hooks, the position of the movable hook 63 can be adjusted by adjusting component 3, thus enabling the hoisting of forgings of different sizes. In addition, when using the clamping arm assembly 5 to clamp the forging, the position of the clamping arm 51 can be adjusted by adjusting component 3 to complete the clamping.

[0032] Mounting assembly 4 includes an inner groove 41 and a base plate 47 formed inside the slider 32. The inner wall of the inner groove 41 has two sets of sliding grooves 42, one at the top and one at the bottom. Each set of sliding grooves 42 consists of four upper and lower sliding grooves 42. A set of semicircular plates 44 is slidably connected between each set of sliding grooves 42. Each set of semicircular plates 44 consists of two symmetrical semicircular plates 44. A rotating rod 45 is rotatably connected to the back of the inner wall of the slider 32. The rotating rod 45 passes through the slider 32 and extends to the outside of the slider 32. The surface of the rotating rod 45 is decorated with… There are two bidirectional threads 46 at the front and back. Each set of two semicircular plates 44 are threaded to both sides of the surface of one bidirectional thread 46. The top of the base plate 47 is fixedly connected to two circular blocks 48 at the front and back, and the two circular blocks 48 correspond to the positions of two through holes 43 respectively. The top of each of the two circular blocks 48 is fixedly connected to a limiting block 49. The middle position of the two limiting blocks 49 is provided with a middle groove 410 corresponding to the position of the bidirectional thread 46. The limiting block 49 is composed of an upper truncated cone part and a lower cylindrical part.

[0033] When using the equipment, the hook assembly 6 and the clamping arm assembly 5 can be replaced by installing component 3, so that the appropriate parts can be selected for hoisting according to the needs, which improves the convenience and functionality of the device.

[0034] The clamping arm assembly 5 includes a clamping arm 51, which is fixedly connected to the bottom of the base plate 47. Two baffles 52 are fixedly connected to the bottom of the clamping arm 51. A fixing rod 53 is fixedly connected between the opposite sides of the two baffles 52. A pressure block 54 is rotatably connected to the surface of the fixing rod 53. A torsion spring 55 is sleeved on the surface of the fixing rod 53 inside the pressure block 54. One end of the torsion spring 55 is fixedly connected to the surface of the fixing rod 53, and the other end of the torsion spring 55 is fixedly connected to the pressure block 54. A groove 56 is provided on one side of the pressure block 54. A hydraulic rod 57 is fixedly connected to the bottom of the clamping arm 51. A push rod 58 is fixedly connected to the telescopic end of the hydraulic rod 57, and the position of the push rod 58 corresponds to that of the groove 56.

[0035] The hook assembly 6 includes a fixed hook 61, which is fixedly connected to the bottom of the base plate 47. A steel cable 62 is attached to the fixed hook 61, and a movable hook 63 is attached to the other end of the steel cable 62.

[0036] When in use, the clamping arm assembly 5 first clamps the forging by adjusting the assembly 3, and then further presses and secures the forging by cooperating with the clamping block through the built-in hydraulic cylinder 57 to avoid slippage.

[0037] In use, select either the clamping arm assembly 5 or the hook assembly 6 as needed. After selection, install the clamping arm assembly 5 or the hook assembly 6 onto the slider 32. During installation, align the limiting block 49 on the base plate 47 with the two through holes 43 and insert it. After insertion, rotate the rotating rod 45. The rotation of the rotating rod 45, through the engagement of the bidirectional thread 46, causes the two opposing semicircular plates 44 to move closer together and clamp onto the outside of the cylindrical part of the limiting block 49. When using the hook assembly 6 for hoisting, start the drive motor 37 to rotate the drive gear 38. The drive gear 38 rotates and transmits power to the gear teeth 36, causing the adjusting disc 3 to... 4. Rotation: The adjustment disc 34 rotates and, through the cooperation of the guide groove 35 and the guide rod 33, causes the slider 32 to move, thereby driving the movable hook 63 to move, thus matching the size of the forging. In addition, when using the clamping arm assembly 5 for hoisting, the drive motor 37 is also started to make multiple clamping arm assemblies 5 move closer to the center at the same time, thereby clamping and fixing the forging. After clamping and fixing, the hydraulic rod 57 is started. The hydraulic rod 57 works to make the push rod 58 move. The push rod 58 moves into the groove 56, thereby abutting against the inner wall of the groove 56, thereby pushing the pressure block 54 to rotate, thereby pressing the pressure block 54 against the surface of the forging.
