Description

Technical Field

[0001] This utility model relates to the technical field of lifting equipment for large-span arch structures, specifically a lifting equipment for large-span arch structures that prevents detachment and swaying. Background Technology

[0002] Large-span buildings typically refer to buildings with a span of 30m or more. When hoisting large-span arch structures, single-machine hoisting or double-machine lifting operations are usually used. Hoisting devices are the most commonly used lifting equipment on construction sites, used to lift construction materials such as steel bars, timber, concrete, and steel pipes. During the construction of buildings, many components need to be lifted using hoisting devices.

[0003] When existing lifting equipment is used to lift large-span arch structures, the arch structure may sway if strong winds occur or if the workers' instructions are not properly followed. Failure to control this swaying in time can lead to structural damage to the arch structure and affect the normal service life of the lifting ropes.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a large-span arch structure lifting device that is resistant to slippage and swaying. Utility Model Content

[0005] The purpose of this invention is to provide a lifting device for large-span arch structures that is resistant to slippage and swaying, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large-span arch structure lifting device with anti-detachment and anti-sway features, including a balance beam. A servo controller is provided on the front surface of the balance beam, and a placement plate is provided on both sides of the upper surface in the middle of the balance beam. A limit rod is slidably mounted through the surface of the servo controller, and a damping shock absorber is installed on the outer surface of the end of the limit rod. The damping shock absorber consists of a damping spring, a damping rod, and a damping bushing. A threaded groove is opened on the outer surface of the damping rod of the damping shock absorber, and a pressure ring is spirally installed on the outer surface of the threaded groove.

[0007] Preferably, a lifting ring is provided at one end of the limiting slide bar near the middle of the balance beam, and a sliding seat is provided on the lower surface of the lifting ring, and the sliding seat is slidably connected to the outer surface of the balance beam.

[0008] Preferably, a second placement plate is provided on both sides of the upper surface of the balance beam, and a rotating rod is rotatably installed on the surface of the second placement plate.

[0009] Preferably, the outer surface of the rotating rod is provided with a second threaded groove, and a drive motor is installed at the end of the rotating rod.

[0010] Preferably, a driving block is spirally mounted on the outer surface of the second threaded groove, and a sliding seat is provided on the lower surface of the driving block.

[0011] Preferably, the sliding seat two is slidably connected to the outer surface of the balance beam, and a rotating disk is rotatably mounted on the lower surface of the sliding seat two.

[0012] Preferably, a lifting rope is installed on the lower surface of the rotating disk, and a hook is provided on the lower surface of the lifting rope.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of a balance lifting beam, servo controller, sliding seat one, lifting ring, placement plate one, limit slide rod, damping shock absorber, pressure ring, and threaded groove, utilizes the damping shock absorber. By sliding the sliding seat one along the balance lifting beam during the lifting of large-span arch structures, the damping shock absorber generates damping, reducing the risk of swaying and collision of the arch structure during lifting, improving lifting safety, better meeting the requirements for anti-detachment and anti-swaying, and reducing wear and fatigue damage caused by vibration. The pressure ring allows for adjustment of the damping shock absorber's pressure adjustment effect, enabling it to be adjusted according to the load borne by the balance lifting beam, thus better matching the damping shock absorber with the entire lifting system and improving the system's stability and reliability.

[0015] 2. This utility model, through the arrangement of a sliding seat, a placement plate, a rotating rod, a drive motor, a threaded groove, a drive block, a rotating disk, a lifting rope, and a hook, utilizes the drive block with the threaded groove to adjust the tension of the lifting rope by sliding along the balance beam when using a balance beam to pull the lifting rope for lifting large-span arch structures, ensuring the balance of the lifting rope during lifting. The rotating disk increases the rotational freedom of the lifting rope during lifting, reduces the torsional force during lifting, reduces wear on the lifting rope, and extends its service life.

[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] like Figures 1-3 As shown, a lifting device for a large-span arch structure with anti-detachment and anti-sway features includes a balance beam 1. A servo controller 101 is mounted on the front surface of the balance beam 1. Placement plates 202 are mounted on both sides of the upper surface of the middle section of the balance beam 1. A limit rod 203 is slidably mounted through the surface of the servo controller 101, and a damping shock absorber 204 is mounted on the outer surface of the end of the limit rod 203. The damping shock absorber 204 consists of a damping spring, a damping rod, and a damping bushing. The advantage of this configuration is that the damping shock absorber 204... The setting of 04, through the setting of the damping shock absorber 204, can generate damping by sliding the sliding seat 12 along the balance lifting beam 1 when lifting a large-span arch structure, thereby reducing the risk of swaying and collision of the arch structure during the lifting process, improving the safety of the lifting, better meeting the requirements of anti-detachment and anti-swaying, and reducing wear and fatigue damage caused by vibration; through the setting of the servo controller 101, the start and stop of the drive motor 303 can be controlled.

[0023] Furthermore, the outer surface of the damping slide rod of the damping damper 204 is provided with a threaded groove 206, and a pressure ring 205 is spirally installed on the outer surface of the threaded groove 206. The advantage of this setting is that the pressure adjustment effect of the damping damper 204 can be adjusted by setting the pressure ring 205, so that it can be adjusted according to the load borne by the balance beam 1, so that the damping damper 204 is better matched with the entire lifting system, thereby improving the stability and reliability of the system.

[0024] Furthermore, a lifting ring 201 is provided at one end of the limiting slide bar 203 near the middle of the balance beam 1, and a sliding seat 2 is provided on the lower surface of the lifting ring 201. The sliding seat 2 is slidably connected to the outer surface of the balance beam 1. The advantage of this setting is that the lifting ring 201 can be limited by the setting of the sliding seat 2, so that it can be stably translated and slid.

[0025] like Figure 4 As shown, both sides of the upper surface of the balance beam 1 are provided with placement plates 301, and a rotating rod 302 is rotatably mounted on the surface of the placement plate 301. The outer surface of the rotating rod 302 is provided with a threaded groove 304, and a drive motor 303 is installed at the end of the rotating rod 302. A drive block 305 is spirally mounted on the outer surface of the threaded groove 304, and a sliding seat 3 is provided on the lower surface of the drive block 305. The advantage of this arrangement is that, through the drive block 305 with the threaded groove 304, when the balance beam 1 pulls the lifting rope 307 to lift the large-span arch structure, the sliding seat 3 can be driven to slide along the balance beam 1 to adjust the tension of the lifting rope 307, ensuring the balance of the lifting rope 307 during lifting.

[0026] Furthermore, the sliding seat 2 3 and the outer surface of the balance beam 1 are configured to slide together, and a rotating disk 306 is rotatably mounted on the lower surface of the sliding seat 2 3. A lifting rope 307 is mounted on the lower surface of the rotating disk 306, and a hook 308 is provided on the lower surface of the lifting rope 307. The advantage of this configuration is that by setting the rotating disk 306, the rotational freedom of the lifting rope 307 during lifting can be increased, the torsional force during lifting can be reduced, the wear of the lifting rope 307 can be reduced, and the service life of the lifting rope 307 can be increased.

[0027] Working principle: When using this anti-detachment and anti-sway large-span arch structure lifting equipment, firstly, the servo controller 101 controls the start drive motor 303 to drive the rotating rod 302 to rotate, which in turn drives the drive block 305 to rotate along the threaded groove 304, causing the sliding seat 3 to slide and adjust the position of the lifting rope 307. After the adjustment is completed, the lifting rope 307 with the hook 308 is connected to the large-span arch structure, and then the crane is started to pull the lifting ring 201 to lift the balance beam 1. If the lifting rope 307 becomes unbalanced during lifting, the servo controller 101 can control the start of the drive motor 303 to adjust the sliding seat 2 3 to slide and tighten the lifting rope 307, ensuring the balance between the lifting ropes 307. If swaying occurs during lifting, the sliding seat 2 can press the damping shock absorber 204 installed at the end of the limit slide rod 203 along the balance lifting beam 1 to dampen and reduce the risk of swaying and collision of the arch structure during lifting, improve the safety of lifting, better meet the requirements of anti-detachment and anti-swaying, and reduce wear and fatigue damage caused by vibration. This is the working principle of the anti-detachment and anti-swaying large-span arch structure lifting equipment.
