[0001] The utility model relates to the technical field of curved truss lifting, in particular to a curved truss installation and lifting device. Background Art

[0002] A curved truss is a structure formed by connecting rods with hinges at both ends. The truss is a plane or spatial structure composed of straight rods and generally has triangular units. The truss rods mainly bear axial tension or pressure, thereby making full use of the strength of the material. When the span is large, it can save materials compared to solid beams, reduce dead weight and increase rigidity. During the installation of the curved truss, a lifting device is required to install it.

[0003] The curved truss lifting device of the prior art is generally used to hook the two ends of the truss through two hooks during use, and then lift and hoist it by a single lifting mechanism. During the lifting process of the truss, due to the influence of its own gravity, the middle part of the truss may be deformed, which is not strong enough and is prone to shaking during the rising process, making the lifting process unstable and reducing the practicality of the lifting device. Therefore, we propose a curved truss installation lifting device to solve the above problems. Utility Model Content

[0007] Furthermore, the lifting frame is fixedly installed on the top of the base, a support plate is fixedly installed between the left side of the lifting frame and the top of the base, two fixed plates are fixedly installed on the top of the lifting frame, a dual-axis motor is fixedly installed on the top of the lifting frame, two output shafts of the dual-axis motor are fixedly installed through a coupling with one end passing through and extending to the outside of the two fixed plates respectively, and winding rollers are fixedly installed on the outer surfaces of the two rotating shafts, and the tops of the two lifting ropes are fixedly connected to the outer surfaces of the two winding rollers respectively.

[0008] Furthermore, there are two support plates, which are respectively located on the left and right sides of the lifting frame, and the bottoms of the two support plates form an angle with the top of the base, and both angles are acute angles.

[0009] Furthermore, the outer surfaces of the two lifting steel ropes are respectively pressed against the outer surfaces of the two discs.

[0013] Furthermore, a through hole is opened inside the lifting frame, and the width of the two limiting plates is larger than the width of the through hole.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-4 A curved truss installation lifting device in this embodiment includes a base 1, a lifting frame 2 and two lifting steel ropes 8. A stabilizing mechanism is arranged on the outside of the lifting frame 2. The lifting frame 2 is fixedly installed on the top of the base 1. A supporting plate 3 is fixedly installed between the left side of the lifting frame 2 and the top of the base 1. Two fixing plates 4 are fixedly installed on the top of the lifting frame 2. A dual-axis motor 5 is fixedly installed on the top of the lifting frame 2. Two output shafts of the dual-axis motor 5 are fixedly installed through a coupling, and one end of the rotating shaft 6 passes through and extends to the outside of the two fixing plates 4 respectively. Winding rollers 7 are fixedly installed on the outer surfaces of the two rotating shafts 6. The tops of the two lifting steel ropes 8 are fixedly connected to the outer surfaces of the two winding rollers 7 respectively.

[0023] Among them, the number of support plates 3 is set to two, and the two support plates 3 are respectively located on the left and right sides of the lifting frame 2. The bottoms of the two support plates 3 form an angle with the top of the base 1, and the two angles are acute angles, which can play a role in reinforcing the lifting frame 2, thereby making the lifting frame 2 more stable during use.

[0024] It should be supplemented that when the lifting device is in use, the base 1 is fixedly connected to the ground, the purpose of which is to prevent the base 1 from being more firm during use.

[0025] By adopting the above technical solution and setting up a stabilizing mechanism, the purpose of stabilizing the lifting frame 2 is achieved, so that the curved truss is more stable during the lifting process, and deformation of the curved truss due to shaking is avoided, thereby better protecting the curved truss and preventing the curved truss from falling during the lifting process, thereby improving the practicability and stability of the curved truss installation lifting device.

[0026] Example 2: Please refer to Figure 1-3 On the basis of the first embodiment, the stabilizing mechanism includes two mounting plates 91 fixedly mounted on the right side of the lifting frame 2, pillars 92 are fixedly mounted on the opposite sides of the two mounting plates 91, and discs 93 are rotatably mounted on the outer surfaces of the two pillars 92. Limiting blocks 94 are fixedly mounted on the outer surfaces of the two lifting steel ropes 8, and connecting rods 95 with one end passing through and extending to the outside of the lifting frame 2 are fixedly mounted on the left sides of the two limiting blocks 94. Two limiting plates 96 are fixedly mounted on the outer surfaces of the two connecting rods 95, and a fixing frame 97 is fixedly mounted on the bottom of the two lifting steel ropes 8, and a hook 98 is fixedly mounted on the outer surface of the fixing frame 97.

[0027] Among them, the outer surfaces of the two lifting steel ropes 8 are respectively squeezed against the outer surfaces of the two discs 93. The purpose is to enable the two discs 93 to support the two lifting steel ropes 8, thereby avoiding the contact between the lifting steel ropes 8 and the lifting frame 2, and then better protecting the lifting steel ropes 8 and increasing the service life of the lifting steel ropes 8.

[0028] Among them, the two limit plates 96 are respectively located on the left and right sides of the lifting frame 2, and the opposite sides of the two limit plates 96 are respectively abutted against the left and right sides of the lifting frame 2. A through hole is opened inside the lifting frame 2, and the widths of the two limit plates 96 are larger than the width of the through hole, thereby achieving the purpose of limiting the two lifting steel ropes 8, so that the two lifting steel ropes 8 will not shake during use, and then the curved truss can be better lifted, thereby improving the stability of the lifting device.

[0029] The fixing frame 97 is an inverted equilateral triangle when viewed from the front, and there are three hooks 98, which are respectively located at the bottom and left and right sides of the fixing frame 97. The purpose is to provide a more stable connection between the curved truss and the fixing frame 97, so that the fixing frame 97 can better lift the curved truss, so that the curved truss will not be deformed due to gravity during the lifting process.

[0030] By adopting the above technical solution, through the coordination of two mounting plates 91, two pillars 92, two discs 93, two limit blocks 94, two connecting rods 95, two limit plates 96, a fixing frame 97 and three hooks 98, the curved truss can be stably lifted, so that the curved truss will not be deformed or fall off during the lifting process, the shaking of the curved truss during the lifting process is reduced, and the stability and safety of the curved truss installation and lifting device are further improved.

[0031] The working principle of the above embodiment is:

[0032] When the curved truss needs to be stably lifted, it is first necessary to connect the top of the curved truss with the three hooks 98, and then start the dual-axis motor 5, so that the dual-axis motor 5 drives the two rotating shafts 6 to rotate, so that the two rotating shafts 6 respectively drive the two winding rollers 7 to wind up at the same time, and then the two lifting steel ropes 8 drive the fixed frame 97 to move upward at the same time. When the lifting steel ropes 8 move upward, the two discs 93 respectively support the two lifting steel ropes 8 at the same time, so that the two limit blocks 94 can also move upward at the same time. The two limit blocks 94 respectively drive the two connecting rods 95 and the four limit plates 96 to move upward at the same time, so that the two connecting rods 95 move up and down in the two through holes respectively, and then the two lifting steel ropes 8 can be limited, thereby completing the stable lifting of the curved truss.
