For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.

[0030] like Figure 1 As shown, an embodiment of the present invention provides a device for quickly hoisting and placing a heavy-duty truss diagonal brace, comprising a display rack and a hoisting rack. The display rack is used to place the diagonal brace 15 to be installed, tilting the diagonal brace 15 at an installation angle. The hoisting rack is disposed above the display rack and is used to hoist the diagonal brace 15, tilting the diagonal brace 15 at the installation angle during the hoisting process. By providing the display rack and the hoisting rack, the diagonal brace 15 can be tilted according to the installation angle during the display and hoisting processes. During the installation process, there is no need to adjust the angle of the diagonal brace 15, thereby improving installation accuracy and efficiency.

[0031] Specifically, the display rack includes a horizontal display bar that supports a plurality of longitudinal display bars 1. The plurality of longitudinal display bars 1 are horizontally arranged and spaced parallel to each other. The plurality of longitudinal display bars 1 are supported at different heights, varying in a stepwise manner, so that the plurality of longitudinal display bars 1 form an inclined display surface. The inclined display surface has an angle that is the same as the installation angle of the diagonal brace bars 15. The diagonal brace bars 15 are placed perpendicular to the longitudinal display bars 1 on the inclined display surface, thereby tilting the diagonal brace bars 15 at the installation angle.

[0032] Specifically, a plurality of longitudinal placement bars 1 are provided with placement reinforcement bars 2. The placement reinforcement bars 2 are arranged perpendicular to the longitudinal placement bars 1 and are fixedly connected to the plurality of longitudinal placement bars 1. A plurality of placement reinforcement bars 2 are provided and arranged at equal intervals to prevent deformation of the longitudinal placement bars 1.

[0033] Specifically, the horizontal placement rod is provided with a vertical support rod 3 and a diagonal support rod 4. The vertical support rod 3 and the diagonal support rod 4 are intersecting at one end, away from the horizontal placement rod, to support the longitudinal placement rod 1. The intersecting ends of the vertical support rod 3 and the diagonal support rod 4 are fixedly connected, and the longitudinal placement rod 1 is placed within and fixedly connected to the intersecting ends. The vertical support rod 3 and the diagonal support rod 4 provide a stable support for the longitudinal placement rod 1.

[0034] Specifically, the horizontal placement rods include a transverse horizontal rod 5 and a longitudinal horizontal rod 6, which are arranged vertically. The vertical support rods 3 and the diagonal support rods 4 are fixed to the transverse horizontal rod 5 at one end close to the horizontal placement rods, and the longitudinal horizontal rods 6 are fixed to both sides of the vertical support rods 3 and the side of the diagonal support rods 4 away from the vertical support rods 3. The longitudinal horizontal rods 6 can play a certain positioning role for the vertical support rods 3 and the diagonal support rods 4, making the support effect of the vertical support rods 3 and the diagonal support rods 4 more secure.

[0035] Preferably, a placement positioning rod 7 is fixed to the lower side of the placement horizontal rod near the placement slope. The placement positioning rod 7 is fixed to the outside of the placement slope and is arranged parallel to the longitudinal placement rod 1. When the diagonal brace 15 is placed on the placement slope, the end of the diagonal brace 15 can abut against the placement positioning rod 7 to prevent the diagonal brace 15 from slipping.

[0036] Specifically, the hoisting frame includes a hoisting horizontal rod 8, which is provided with a fixed angle hoisting rod for tilting the diagonal brace 15 at an installation angle. A lifting lug 14 is fixed at the middle of the hoisting horizontal rod 8 for connecting a lifting device.

[0037] Specifically, the fixed-angle suspender includes a first suspender 9 and a second suspender 10. The first suspender 9 and the second suspender 10 are of different lengths and are arranged vertically. The tops of the first suspender 9 and the second suspender 10 are fixedly connected to the hoisting horizontal rod 8. The distance between the first suspender 9 and the second suspender 10 is the same as the horizontal distance between the two lifting ears 14 on the diagonal brace 15 when the suspender 15 is tilted. Due to the different lengths of the first suspender 9 and the second suspender 10, they are used to connect to the two lifting ears 14 on the diagonal brace 15, respectively, so that the diagonal brace 15 maintains the installation angle and is hoisted at an angle.

[0038] Preferably, in order to facilitate connection, a lifting ring is fixed to the bottom of the first hanger 9 and the second hanger 10, and a lifting rope is connected to the lifting ring, and the lifting rope can be connected to the lifting lug 14 on the diagonal member 15. If the length of the first hanger 9 and the second hanger 10 is set according to the installation angle of the diagonal member 15, the lifting ropes connected to the first hanger 9 and the second hanger 10 can be set to the same length. During the specific construction process, if the processing length of the first hanger 9 and the second hanger 10 deviates, so that the lifting angle of the diagonal member 15 deviates from the installation angle, the lifting angle can be fine-tuned by adjusting the length of the lifting ropes at the bottom of the first hanger 9 and the second hanger 10 to ensure that the lifting angle is consistent with the installation angle.

[0039] Preferably, a hoisting reinforcement rod 13 is fixed between the first hoisting rod 9 and the second hoisting rod 10. The hoisting reinforcement rod 13 is fixed crosswise and tilted.

The intersection ends of the vertical support bars 3 and the diagonal support bars 4 are fixedly connected, and the longitudinal placement bars 1 are placed within the intersection end and fixedly connected to the intersection end. The horizontal placement rods include a transverse horizontal rod 5 and a longitudinal horizontal rod 6, which are arranged vertically. The vertical support rods 3 and the diagonal support rods 4 are fixed to the transverse horizontal rod 5 at their ends closest to the placement rods. The longitudinal horizontal rods 6 are fixed to both sides of the vertical support rods 3 and to the side of the diagonal support rods 4 away from the vertical support rods 3.

The tops of the first hanging rod 9 and the second hanging rod 10 are fixedly connected to the lifting horizontal rod 8. The distance between the first hanging rod 9 and the second hanging rod 10 is the same as the horizontal distance between the two lifting lugs 14 on the diagonal brace 15 when the placement is tilted. A lifting ring is fixed at the bottom of the first and second suspenders 9 and 10, and a lifting rope is connected to the lifting ring. The lifting rope can be connected to the lifting lug 14 on the diagonal brace 15. A lifting reinforcement rod 13 is fixed between the first and second suspenders 9 and 10.
