Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary device for hoisting steel pipe trusses, belonging to the technical field of steel pipe truss hoisting devices. Background Technology
[0002] A tubular truss is a lattice structure composed of round rods connected at their ends. The trusses make the truss structure economical in terms of material usage and lightweight, and easy to form various shapes to suit different uses. For example, it can be made into a simple truss, arch, frame, and tower. When installing a steel tubular truss, hoisting auxiliary equipment is required to lift it and assist in the installation.
[0003] According to announcement number CN218619838U, a steel pipe truss hoisting auxiliary device is provided. This utility model can easily separate from the steel pipe truss after hoisting, thereby improving the work efficiency of the entire installation process of the steel pipe truss. However, the above-mentioned device requires workers to perform multiple operations when hoisting the steel pipe truss, making the device inconvenient to use. At the same time, because the support rod moves upward due to the worker's operation, it cannot effectively ensure that the support rod and the clamping seat clamp the steel pipe truss, thus failing to guarantee the stability of the device when hoisting the steel pipe truss. Consequently, if the steel pipe truss is hit by external objects during hoisting, it is easy for it to shift on the hoisting device, causing the center of gravity of the steel pipe truss to shift, which can easily cause the hoisting device to tilt. Therefore, the safety of the device when hoisting the steel pipe truss is not high, thus reducing the practicality of the device. Utility Model Content

[0021] 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.
[0022] Please refer to Example 1 Figures 1-4 This utility model provides a technical solution:
[0023] A steel pipe truss hoisting auxiliary device includes a crossbar 1, a lifting rod 2 fixedly mounted at the top of the crossbar 1, a lifting ring 3 fixedly mounted at the top of the lifting rod 2, a second crossbar 4 symmetrically slidably mounted at the bottom of the crossbar 1, a fixed seat 5 symmetrically slidably mounted at the bottom of each of the second crossbars 4, a fixed rod 6 fixedly mounted at the bottom of each of the fixed seats 5, a support rod 7 rotatably mounted at the bottom of each of the fixed rods 6, a support plate 8 fixedly mounted at the bottom of each of the support rods 7, a hydraulic cylinder 9 fixedly mounted at the bottom of the crossbar 1, a pressure plate 10 fixedly connected to the output end of the hydraulic cylinder 9, and through slots symmetrically opened on both sides of the pressure plate 10 for the movement of the fixed rods 6.
[0024] Specifically, such as Figures 1-4As shown, a groove 11 is provided inside the crossbar 1. A double-headed motor 12 is fixedly installed on the inner wall of the middle part of the groove 11. The output ends of the double-headed motor 12 are fixedly connected to screws 13. Slider 14 is threaded onto each screw 13. The bottom end of each slider 14 is fixedly connected to the top end of the adjacent crossbar 4. The two screws 13 have threads in opposite directions. L-shaped brackets 15 are symmetrically fixed to the top end of each crossbar 4. The L-shaped brackets 15 are fixedly connected to the adjacent sliders 14. The double-headed motor 17 drives the screws 13 to rotate, thereby causing the screws 13 to drive the sliders 14 to move within the groove 11. The sliders 14 can drive the crossbar 4 to move towards each other or away from each other. At the same time, the L-shaped brackets 15 can support the crossbar 4, thereby improving the stability of the crossbar 4.
[0025] Specifically, such as Figures 1-4 As shown, each of the two crossbars 4 has a groove 16 at its bottom. A double-headed motor 17 is fixedly installed on the inner wall of the middle part of each groove 16. The output end of each double-headed motor 17 is fixedly connected to a screw 18. Each screw 18 has a slider 19 threaded on it. The bottom end of each slider 19 is fixedly connected to the top end of the adjacent fixed seat 5. Each of the two adjacent screws 18 has threads in opposite directions. The double-headed motor 17 drives the screw 18 to rotate, and the screw 18 drives the slider 19 to move within the groove 16. The slider 19 can drive the corresponding fixed seat 5 to move towards each other or away from each other.
[0026] Specifically, such as Figures 1-4 As shown, each of the fixed rods 6 is provided with a rotating block 20, the bottom end of which is fixedly connected to the top end of the adjacent support rod 7. Each of the lower sides of the fixed rod 6 is provided with a threaded locking screw 21. By rotating the support rod 7, the support rod 7 drives the support plate 8 to rotate to a suitable angle. At this time, the support rod 7 drives the rotating block 20 to rotate inside the fixed rod 6. Then, the locking screw 21 is tightened to fix the rotating block 20, thereby fixing the support rod 7 and the support plate 8.
[0027] Specifically, such as Figures 1-4 As shown, slide rods 22 are fixedly provided on both top ends of the pressure plate 10. The top ends of the slide rods 22 extend through the crossbar 1 to the top of the crossbar 1. When the pressure plate 10 moves, the pressure plate 10 will drive the slide rods 22 to move on the crossbar 1. The slide rods 22 can support the pressure plate 10.
[0028] Please refer to Example 2 Figures 1-4The difference between this embodiment and embodiment 1 is that anti-slip pads are fixedly provided at the top of the support plate 8 and the bottom of the pressure plate 10. By setting anti-slip pads, the stability of the device during the hoisting of the steel pipe truss can be improved.
[0029] The working principle of this utility model is as follows: During use, the angle of the support plate 8 is adjusted according to the structure of the steel pipe truss. By rotating the support rod 7, the support rod 7 drives the support plate 8 to rotate to a suitable angle. At this time, the support rod 7 drives the rotating block 20 to rotate within the fixed rod 6. Then, the locking screw 21 is tightened to fix the rotating block 20, thereby fixing the support rod 7 and the support plate 8. The double-headed motor 17 drives the screw 13 to rotate, causing the screw 13 to drive the slider 14 to move within the slide groove 11. The slider 14 can drive the crossbar 4 to move in opposite directions or backwards. Simultaneously, the L-shaped frame 15 provides support for the crossbar 4, thereby improving its stability and allowing adjustment of the crossbar 4 to... At a suitable position, the double-headed motor 17 drives the screw 18 to rotate, which in turn drives the slider 19 to move within the groove 16. The slider 19 then moves the corresponding fixed seat 5 in opposite directions, thereby adjusting the support plate 8 to the appropriate position. The support plate 8 is then inserted into the steel pipe truss. The double-headed motor 17 then reverses its operation, lifting the device upwards. The support plate 8 then supports the steel pipe truss. The hydraulic cylinder 9 pushes the pressure plate 10 downwards, pressing the steel pipe truss tightly. As the pressure plate 10 moves, it drives the slide rod 22 to move on the crossbar 1. The slide rod 22 supports the pressure plate 10, thus improving the stability of the steel pipe truss during hoisting.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
