[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] like Figures 1 to 7 As shown, as one embodiment of the steel structure hoisting device 100, the steel structure hoisting device 100 is used to clamp a steel structure (e.g., a steel pipe 200), including a truss 10 and two sets of clamping assemblies 20, wherein the two sets of clamping assemblies 20 are symmetrically arranged at opposite ends of the truss 10 for clamping the steel structure; as Figures 3 to 5As shown, the clamping assembly 20 includes a motor 21, a first gear shaft 22, a transmission bevel gear 23, a second gear shaft 24, a third gear shaft 25, and a clamping arm 26. The motor 21 has a rotating shaft. The first gear shaft 22 includes a first bushing 221 and a first bevel gear 222 disposed at one end of the first bushing 221. The first bushing 221 is fixedly connected to the rotating shaft of the motor 21. The transmission bevel gear 23 is mounted on the truss 10 and meshes with the first bevel gear 222. The second gear shaft 24 is on the same axis as the first gear shaft 22. The second gear shaft 24 includes a second bushing 241 and a second bevel gear 242 and a first drive gear 243 respectively disposed at both ends of the second bushing 241. The second bushing 241 is sleeved on the first bushing 221. The second bevel gear 242 meshes with the transmission bevel gear 25. Gear 23 meshes; the third gear shaft 25 includes a transmission shaft body 251 and a second drive gear 252 disposed at one end of the transmission shaft body 251, the transmission shaft body 251 is inserted and fixed inside the first bushing 221; the clamping arm 26 includes a clamping sleeve 261 and a first annular clamping part 262 and a second annular clamping part 263 disposed side by side inside the clamping sleeve 261, the clamping sleeve 261 is installed at the end of the truss 10, the first annular clamping part 262 meshes with the first drive gear 243, the second annular clamping part 263 meshes with the second drive gear 252, the rotation directions of the first drive gear 243 and the second drive gear 252 are opposite, so that the first annular clamping part 262 and the second annular clamping part 263 can move away from or close to each other, so as to achieve clamping or releasing of the steel structure.
[0024] In this embodiment, the steel structure hoisting device 100 is suitable for installation on a crane, capable of clamping the steel structure and lifting it to a certain height via the crane. When the motor 21 is working, its shaft drives the first gear shaft 22 to rotate coaxially; the first bevel gear 222 in the first gear shaft 22 drives the transmission bevel gear 23 to rotate, and the rotation directions of the first bevel gear 222 and the transmission bevel gear 23 are opposite. For example, if the first bevel gear 222 rotates counterclockwise, then the transmission bevel gear 23 rotates clockwise; the transmission bevel gear 23 also meshes with the second bevel gear 242, driving the second gear shaft 24 to rotate clockwise around the first bushing 221, that is, the first drive gear 243 rotates clockwise; while the third gear shaft 25 is fixedly connected to the first bushing 221 and rotates coaxially with the first gear shaft 22, that is, the second drive gear 252 in the third gear shaft 25 rotates counterclockwise.
[0025] Therefore, in this embodiment, the rotation direction of the first drive gear 243 is opposite to that of the second drive gear 252. Thus, the first drive gear 243 can drive the first annular clamping part 262 to rotate counterclockwise, and the second drive gear 252 can drive the second annular clamping part 263 to rotate clockwise, thereby clamping the steel structure (e.g., the steel pipe 200); or the first drive gear 243 can drive the first annular clamping part 262 to rotate clockwise, and the second drive gear 252 can drive the second annular clamping part 263 to rotate counterclockwise, thereby releasing the steel structure (e.g., the steel pipe 200). In this embodiment, the clamping assembly 20 has two sets, which can clamp the two ends of the steel structure in the length direction respectively, preventing the steel structure from falling and ensuring good stability of the hoisting.
[0026] Furthermore, such as Figure 7 As shown, in order to facilitate the connection between the steel structure hoisting device 100 and the crane, the truss 10 includes a transverse support 11 and a connecting support 12 located in the middle of the transverse support 11. The connecting support 12 is connected and fixed to the crane, thereby facilitating the lifting and lowering of the steel structure hoisting device 100. Two sets of clamping components 20 are symmetrically installed on the transverse support 11.
[0027] Furthermore, in combination Figure 1 and Figure 4 To facilitate the installation of the clamping assembly 20, the steel structure hoisting device 100 also includes two mounting bases 30, which are symmetrically arranged at the two ends of the truss 10 that are far apart from each other. The motor 21 is fixed to the mounting base 30. Specifically, the mounting base 30 includes a transverse support plate 31 and a lateral support plate 32 perpendicular to the transverse support plate 31, and the motor 21 is fixed to the transverse support plate 31.
[0028] Furthermore, such as Figure 4 As shown, in order to install and position the transmission bevel gear 23, the clamping assembly 20 also includes a vertical column 27 perpendicular to the mounting base 30 (specifically the horizontal support plate 31). The center of the transmission bevel gear 23 is movably connected to the top of the vertical column 27, so that the transmission bevel gear 23 can rotate.
[0029] Furthermore, such as Figure 4 As shown, the clamping assembly 20 also includes a bearing seat 28 mounted on the mounting base 30 (specifically, the transverse support plate 31), and a second bushing 241 passes through the bearing seat 28 and is rotatably connected to the bearing seat 28, so that the second bushing 241 can rotate around the first bushing 221, and the rotation direction of the second bushing 241 is opposite to that of the first bushing 221.
[0030] Furthermore, such as Figure 5As shown, the transmission shaft body 251 of the third gear shaft 25 is fixedly connected to the first bushing 221 by a pin. Pin holes are provided on both the transmission shaft body 251 and the first bushing 221 to ensure that the third gear shaft 25 and the first gear shaft 22 rotate coaxially. Simultaneously, the first bushing 221 is also fixedly connected to the rotating shaft of the motor 21 by a pin.
[0031] Furthermore, such as Figure 3 As shown, the clamping sleeve 261 includes a first clamping plate 2611, a second clamping plate 2612, a plurality of inner ring stop posts 2613, and a plurality of outer ring stop posts 2614. The first clamping plate 2611 and the second clamping plate 2612 are arranged opposite to each other and are both semi-circular. The plurality of inner ring stop posts 2613 are arranged circumferentially between the first clamping plate 2611 and the second clamping plate 2612. The inner ring stop posts 2613 and the first clamping plate 2611 are located at... The center of the circumference has a first radius; a plurality of outer ring stop posts 2614 are arranged circumferentially between the first clamping plate 2611 and the second clamping plate 2612, and the center of the circumference where the outer ring stop posts 2614 and the first clamping plate 2611 are located has a second radius. The first radius is smaller than the second radius, so that the first annular clamping part 262 and the second annular clamping part 263 can be accommodated between the outer ring stop posts 2614 and the inner ring stop posts 2613.
[0032] Preferably, in this embodiment, both the inner ring stop post 2613 and the outer ring stop post 2614 are movably connected between the first clamping plate 2611 and the second clamping plate 2612, so that the friction between the first annular clamping part 262 and the second annular clamping part 263 and the inner ring stop post 2613 and the outer ring stop post 2614 is reduced during rotation.
[0033] like Figure 6 As shown, the first clamping plate 2611 is also provided with a notch 26111 for the first drive gear 243 and the second drive gear 252 to pass through, so that the first drive gear 243 passes through the notch 26111 and meshes with the first annular clamping part 262, and the second drive gear 252 can pass through the notch 26111 and mesh with the second annular clamping part 263.
[0034] Furthermore, such as Figure 3 As shown, both the first annular clamping part 262 and the second annular clamping part 263 have a slender annular structure, preferably a semi-circular annular structure; the outer contour of the first annular clamping part 262 has a first adjusting tooth 2621 that meshes with the first drive gear 243, and the outer contour of the second annular clamping part 263 has a second adjusting tooth 2631 that meshes with the second drive gear 252.
[0035] This embodiment also provides a hoisting device, which includes a crane and the aforementioned steel structure hoisting device 100 installed on the crane.
[0036] Preferably, the steel structure hoisting device 100 also includes a first controller, which can control the starting and turning of the motor 21. The hoist has a second controller electrically connected to the first controller. Through mutual communication between the second controller and the first controller, the operation of the steel structure hoisting device 100 is controlled.
[0037] Finally, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this application, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0038] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
