Description

Technical Field

[0001] This utility model relates to the field of steel truss installation technology, specifically to an installation device for steel trusses. Background Technology

[0002] Steel trusses refer to trusses made of steel. They are used in industrial and civil buildings for roof structures, crane beams, bridges, and hydraulic gates. Steel trusses are commonly used as the main load-bearing components. Various types of towers, such as mast towers, television towers, and transmission line towers, are often spatial steel trusses composed of three-sided, four-sided, or multi-sided planar trusses.

[0003] Currently, large steel trusses are usually installed using mechanical equipment such as cranes, while small steel trusses, due to their relatively small size and weight, are mostly installed manually. However, manual installation not only consumes a lot of physical strength, but also makes it difficult to accurately control the height. When operating manually, the stability of the support structure depends entirely on the experience of the construction personnel. Under large loads, it is prone to swaying or tilting, which seriously affects the installation accuracy and construction safety of the steel truss. Therefore, an installation device for steel trusses is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figure 1-3 As shown, this utility model provides an installation device for steel trusses, including a base 1, a hydraulic lifting rod 2, and a support frame 3. The bottom of the hydraulic lifting rod 2 is installed at the center of the upper surface of the base 1. An installation plate 9 is installed on the outer side of the upper end of the hydraulic lifting rod 2. A rotating device is installed on the upper end of the installation plate 9. The bottom of the support frame 3 is installed on the upper surface of the rotating device. A clamping assembly is installed on the inner side of the support frame 3. Multiple sets of support assemblies are installed on the upper surface of the base 1.

[0021] Specifically, the hydraulic lifting rod 2 and rotating device allow for quick and precise adjustment of height and angle without requiring manual labor, meeting the installation needs of small steel trusses of different heights, reducing the labor intensity of construction workers, and significantly improving construction efficiency. The supporting components increase the stability of the small steel truss load, preventing swaying or tilting during installation, thus ensuring construction safety and the installation accuracy of the steel truss. The clamping device firmly fixes the steel truss, ensuring stability during installation and facilitating the clamping of steel trusses of different sizes.

[0022] The rotating device includes a driven wheel 10, rotating blocks 11 and 12, a transmission wheel 13, a reducer 14, and a rotary motor 15. The rotating block 11 is rotatably mounted on the top of the hydraulic lifting rod 2. The driven wheel 10 is mounted on the outside of the rotating block 11. The rotary motor 15 is mounted on the lower surface of the mounting plate 9, and its output end passes through the mounting plate 9 and is connected to the reducer 14. The reducer 14 is mounted on the upper surface of the mounting plate 9, and its output end is connected to the transmission wheel 13. The transmission wheel 13 meshes with the driven wheel 10. By starting the rotary motor 15, the reducer 14 is driven to rotate. The reducer 14 reduces the speed and increases the torque, thereby driving the transmission wheel 13 to rotate. The rotation of the transmission wheel 13 drives the meshing driven wheel 10 to rotate, thereby driving the rotating block 11 to rotate at the top of the hydraulic lifting rod 2. The rotation of the hydraulic lifting rod 2 drives the support frame 3 to rotate, thus facilitating the adjustment of the installation direction of the steel truss.

[0023] The clamping assembly includes a second turntable 16, a second threaded rod 17, and a clamping plate 18. The clamping plate 18 is disposed inside the support frame 3. The second threaded rod 17 is threadedly connected to the inside of one side of the support frame 3. One end of the second threaded rod 17 is rotatably mounted on the side surface of the clamping plate 18, and the other end is mounted on the surface of the second turntable 16. The second turntable 16 is disposed on one side of the support frame 3. By rotating the second turntable 16, the second threaded rod 17 is driven to rotate inside one side of the support frame 3. The rotation of the second threaded rod 17 drives the clamping plate 18 connected to one end to move, thereby clamping and fixing the steel truss inside the support frame 3, ensuring stability during installation, and facilitating the clamping of steel trusses of different sizes.

[0024] Among them: the surface of the support frame 3 is provided with a sliding groove 19, and two sets of sliding grooves 19 are provided. The bottom of the clamping plate 18 is equipped with a slider 20, and two sets of sliders 20 are provided. The slider 20 is slidably disposed inside the sliding groove 19. Through the provided sliding groove 19 and slider 20, the stability of the clamping plate 18 when moving can be increased and deviation can be avoided.

[0025] The support assembly includes a telescopic plate 4, a first threaded rod 5, a first turntable 6, and a support plate 8. The telescopic plate 4 is installed on the upper surface of the base 1. The first threaded rod 5 is threadedly connected to the inside of the extension end of the telescopic plate 4. The first turntable 6 is installed on the upper surface of the first threaded rod 5. The support plate 8 is rotatably installed on the lower surface of the first threaded rod 5. By pulling the extension end of the telescopic plate 4 outward, and then rotating the first turntable 6, the first threaded rod 5 moves inside the rotating end of the telescopic plate 4. The rotation of the first threaded rod 5 causes the support plate 8 to move downward and make it fit tightly against the ground, which can increase the stability during the installation process.

[0026] Among them, the lower surface of the base 1 is equipped with casters 7. There are multiple sets of casters 7, and they are equipped with a braking function. The casters 7 make it easy to move the device to different positions for installation.

[0027] Working Principle: This utility model is an installation device for steel trusses. First, the steel truss is placed inside the support frame 3. Then, the second turntable 16 is rotated, causing the second threaded rod 17 to rotate inside one side of the support frame 3. The rotation of the second threaded rod 17 causes the clamping plate 18 connected to one end to move, and causes the slider 20 to slide inside the slide groove 19, thereby fixing and clamping the steel truss. Then, the device is pushed to the installation location of the steel truss. At this time, the extension end of the telescopic plate 4 is pulled outward. Then, the first turntable 6 is rotated, causing the first threaded rod 5 to move inside the rotating end of the telescopic plate 4. The rotation of the first threaded rod 5 causes the support plate 8 to move downwards and press against the ground. Then, the hydraulic lifting rod 2 is activated to lift the support frame 3, thereby moving the steel truss upwards to the installation position. The rotary motor 15 is activated to drive the reducer 14 to rotate. The reducer 14 reduces the speed and increases the torque, thereby driving the transmission wheel 13 to rotate. The rotation of the transmission wheel 13 drives the meshing driven wheel 10 to rotate, thereby driving the rotating block 11 to rotate at the top of the hydraulic lifting rod 2. The rotation of the rotating block 11 drives the support frame 3 to rotate, thus facilitating the adjustment of the installation direction of the steel truss.
