Description

Technical Field

[0001] The present invention relates to the field of steel component production and processing, and in particular to a lifting auxiliary device for steel component galvanizing operations. Background Art

[0002] It is well known that in modern steel structure construction and maintenance, galvanizing is an important process to improve the corrosion resistance of steel components and extend their service life. With the rapid development of the construction industry and infrastructure construction, the types and shapes of steel components are becoming increasingly diverse. In particular, the demand for special-shaped steel components in practical applications is constantly increasing. Although these special-shaped steel components have certain advantages in structural design, for existing lifting tools, they are prone to the following problems during the lifting process:

[0003] Currently, most common lifting auxiliary devices on the market are standardized products, which are mainly designed for steel components of conventional shapes. Therefore, the existing auxiliary devices are not adjustable enough, which makes them unable to adapt to the sizes and shapes of different steel components. In particular, for some special special-shaped steel components, additional tools or equipment are often required to assist in the lifting process, which increases the complexity and time cost of the operation. In addition, the existing lifting auxiliary devices cannot effectively match the geometric characteristics of special-shaped steel components, resulting in the components being difficult to maintain stability during the lifting process. They are prone to tilting or rotation due to the shift of the center of gravity, thereby affecting the safety of construction. Therefore, there are certain safety hazards. Summary of the Invention

DETAILED DESCRIPTION

[0037] The following description is merely illustrative in nature and is not intended to limit the present disclosure, its applications, or uses. It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure. Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0038] like Figures 1-9As shown: This embodiment provides a technical solution: a lifting auxiliary device for galvanizing steel components, comprising a hanging plate frame 1, a suspension frame 4 and a binding frame 5, wherein the hanging plate frame 1 adopts a circular ring structure, and a boom group 3 is installed below the hanging plate frame 1, and the boom group 3 includes a first arm 30 and a second arm 31, and the first arm 30 and the second arm 31 are rotatably connected at the center, so that the first arm 30 and the second arm 31 can adjust the included angle by rotation, and the first arm 30 and the second arm 31 both include a horizontal section 33 and a lower inclined section 34, one end of the suspension 4 is rotatably connected to the bottom of the lower inclined section 34 through a first rotating member 36, and the other end is movably connected to the bottom of the lower inclined section 34 through a hydraulic rod 6, so that the hydraulic rod 6 can push the suspension 4 to rotate and adjust the angle during operation, and the binding frame 5 is installed at the bottom of the suspension 4 for fixing the steel component, and the binding frame 5 can move along the length direction of the suspension 4;

[0039] Working principle: The hoisting plate frame 1 in the device is installed under the hoisting crane and is used to cooperate with the crane to hoist the steel structure into the galvanizing equipment. When the device is in use, first, according to the actual shape of the steel structure and the hoisting position of the steel structure as a reference, the first arm 30 and the second arm 31 are controlled to rotate and adjust the angle, so that the binding frame 5 under the first arm 30 and the second arm 31 are moved to the hoisting position of the steel structure, and then the multiple fixed points on the steel structure are fixed by the binding frame 5 to achieve auxiliary hoisting.

[0040] In summary, the device installs the tie frame 5 for fixing the steel structure below the first arm 30 and the second arm 31, and the first arm 30 and the second arm 31 are connected by central rotation. Therefore, the first arm 30 and the second arm 31 can adjust the angle by rotation, and then move the tie frame 5 to change the position of the tie frame 5 on the suspension 4 to correspond to the fixed position of the steel structure. Therefore, the adjustability of the device can be higher, thereby improving the applicability of the device. In addition, the tie frame 5 is located at the two symmetrical end points of the first arm 30 and the second arm 31, making it relatively more stable during the hoisting process, thereby improving the safety of the hoisting. At the same time, since the tie frame 5 is installed below the suspension 4, and the suspension 4 can control the adjustment angle through the hydraulic rod 6, the tie frame 5 can be kept parallel to the upper surface of the fixed position of the steel structure, thereby improving the fit between the tie frame 5 and the steel structure and ensuring the safety of the hoisting process.

[0041] Specifically, such as Figure 6-Figure 8 As shown, in order to achieve the movable control of the binding frame 5, in this embodiment, a guide groove 402 is formed at the bottom of the suspension frame 4 along the length direction. A screw rod 403 is rotatably installed inside the guide groove 402 along the length direction. A second motor 400 is fixedly installed at one end of the suspension frame 4, and the output shaft of the second motor 400 is connected to one end of the screw rod 403.

[0042] A movable frame 401 is movably assembled inside the guide groove 402, and the binding frame 5 is fixed to the bottom of the movable frame 401. A screw nut 404 is nested and installed inside the movable frame 401. The screw nut 404 is adapted to the screw rod 403, and the screw rod 403 is sleeved inside the screw nut 404. Based on this, when the second motor 400 is running, it can drive the screw rod 403 to rotate. Through the cooperation of the screw nut 404 and the screw rod 403, the movable frame 401 can slide along the length direction in the guide groove 402, thereby realizing the adjustment and control of the position of the binding frame 5.

[0043] Specifically, such as Figure 8-Figure 9 As shown, in order to achieve the fixation of the binding frame 5 to the steel member, in this embodiment, the binding frame 5 includes a hanger 50 and a strap 52, wherein the hanger 50 is fixed below the movable frame 401, and the strap 52 is arranged below the hanger 50 for binding and fixing the steel member. One end of the strap 52 is a movable end, and the other end is a retracted end. The movable end of the strap 52 is detachably engaged with one side of the hanger 50, and the retracted end of the strap 52 is fixed to the tightening mechanism, so that when the steel member needs to be fixed, the movable end of the strap 52 is first opened, and the strap 52 is locked after passing around the fixed point of the steel member, and then the strap 52 is gradually tightened by the tightening mechanism until the strap 52 covers and tightens the steel member, that is, the fixation of the steel member by the binding frame 5 is completed, and the operation is convenient and quick.

[0044] Specifically, such as Figure 8-Figure 9 As shown, in order to tighten the strap 52, in this embodiment, the tightening mechanism includes a strap chamber 51 installed at one end of the hanger 50, and a winding shaft 511 is rotatably installed inside the strap chamber 51. A third motor 510 is installed at one end of the strap chamber 51, and the output shaft of the third motor 510 is connected to one end of the winding shaft 511. The winding end of the strap 52 is fixed on the winding shaft 511, so that the third motor 510 can drive the winding shaft 511 to rotate when it is running, and the winding shaft 511 can drive the strap 52 to be wound around the winding shaft 511 when it rotates, thereby tightening the strap 52.

[0045] Specifically, such as Figure 8-Figure 9 As shown, in order to realize the detachable installation of the movable end of the strap 52, in this embodiment, a strap threading groove 504 is provided at the bottom of the hanger 50 below the strap receiving chamber 51, an open groove 500 is provided at the end of the hanger 50 away from the strap receiving chamber 51, and rod clamping grooves 501 are provided on both sides of the open groove 500 above the hanger 50. An end rod 53 is fixed to the movable end of the strap 52, and the winding end of the strap 52 passes through the strap threading groove 504 and enters the strap receiving chamber 51 and is fixedly connected to the winding shaft 511. The end rod 53 on the movable end of the strap 52 can be inserted into the rod clamping groove 501 through the open groove 500, so that the movable end of the strap 52 can be detachably installed.

[0046] Specifically, such as Figure 8-Figure 9As shown, in order to prevent the end rod 53 from accidentally falling out of the rod clamping slot 501 during the hoisting process, in this embodiment, a protective mechanism 54 is further installed inside the hanger 50, and the protective mechanism 54 includes a cavity 502 opened in the hanger 50 and a baffle 541 installed in the cavity 502, wherein the baffle 541 is connected to the inner wall of the cavity 502 by a spring 542, one end of the baffle 541 extends into the rod clamping slot 501 and is stuck above the end rod 53, and a movable groove 503 communicating with the cavity 502 is opened on the top of the hanger 50, and a push-pull plate 540 is installed above the baffle 541, and the push-pull plate 540 passes through the movable groove 503 and extends to the The outside, and the push-pull plate 540 can move along the length direction of the movable groove 503. Based on this, when the strap 52 fixes the steel structure, the end rod 53 is engaged in the rod slot 501, and the baffle 541 extends its front end into the rod slot 501 under the elastic force of the spring 542, and is stuck above the end rod 53, locking the end rod 53 in the rod slot 501 to prevent it from accidentally falling out. When the strap 52 needs to be removed, the baffle 541 is pushed by the push-pull plate 540 to move, so that the front end of the baffle 541 moves into the cavity 502, and the top of the rod slot 501 is opened. At this time, the end rod 53 can be directly taken out from the rod slot 501, and the strap 52 can be removed, which is convenient and quick to operate.

[0047] Specifically, such as Figure 5-Figure 6 As shown, in order to achieve angle adjustment control of the suspension 4 so that the top of the tie frame 5 can be parallel to the upper surface of the fixed position of the steel member, in this embodiment, end slots 35 are formed at both ends of the first arm 30 and the second arm 31. The first rotating member 36 is rotatably mounted in the end slots 35 via a rotating shaft. One end of the suspension 4 is fixedly connected to the first rotating member 36 via an end connecting member 37, so that the suspension 4 can rotate about the central axis of the first rotating member 36;

[0048] Both ends of the hydraulic rod 6 are rotatably connected to the lower inclined section 34 and the suspension 4 through a movable connecting member 60. The movable connecting member 60 includes two parallel vertical plates 601 and a second rotating member 600 rotatably installed between the two vertical plates 601. The two ends of the hydraulic rod 6 are respectively installed on the two second rotating members 600, so that when the hydraulic rod 6 is running, it can push the suspension 4 to rotate with the central axis of the first rotating member 36 as the rotation axis, thereby realizing the angle adjustment control of the suspension 4.

[0049] Specifically, such as Figure 1-Figure 5As shown, in order to enable the first arm 30 and the second arm 31 to adjust the angle by rotation, in this embodiment, a through slot 300 is provided in the middle of the horizontal section 33 of the first arm 30, and a clamping portion 310 is provided in the middle of the horizontal section 33 of the second arm 31. The clamping portion 310 passes through the through slot 300, and the centers of the first arm 30 and the second arm 31 are rotatably connected by a rotating shaft. Based on this, the first arm 30 and the second arm 31 can be relatively rotated within a certain range to adjust the size of the angle, thereby achieving the effect of adjusting the position of each binding frame 5.

[0050] Specifically, such as Figure 1-Figure 5 As shown, in order to realize the rotation angle control of the first arm 30 and the second arm 31, in this embodiment, four arm movable grooves 10 for the first arm 30 or the second arm 31 to pass through are opened on the side of the hanging plate frame 1, and a fixed plate 11 is installed on the upper inner side of the hanging plate frame 1 at the middle position of the arm movable groove 10, and a first motor 13 is fixedly installed above the fixed plate 11.

The top of the first arm 30 and the second arm 31 are both installed with a gear ring 32, and the gear ring 32 adopts a circular arc structure, and the gear ring 32 is meshed with the gear 12. Based on this, when the first motor 13 is running, it drives the gear 12 to rotate. Under the linkage action of the gear ring 32, the first arm 30 or the second arm 31 can be rotated to adjust the angle.

[0051] Specifically, such as Figure 1-Figure 5 As shown, in order to ensure the stability of the first arm 30 and the second arm 31 during rotation and to realize the installation of the hanging plate frame 1, in this embodiment, a mounting column 2 is provided above the central axis of the hanging plate frame 1, and the mounting column 2 is used to connect with the mechanical arm of the crane. The outer edge of the mounting column 2 is fixedly connected to the hanging plate frame 1 through a plurality of support rods 20 in a circular array, and a vertical pole 21 is provided below the middle of the mounting column 2. The rotating shaft connected between the first arm 30 or the second arm 31 is rotatably installed at the bottom of the vertical pole 21.
