Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a stabilizing mechanism for vertical lifting equipment. Background Technology

[0002] In the field of logistics and handling, vertical lifting slings are the core equipment for vertical transfer of heavy objects. Their operational stability directly determines the transfer efficiency, operational safety, and equipment lifespan. The power transmission and lifting guidance of vertical lifting slings rely on the lifting wire rope. However, in practical applications, the lifting wire rope is prone to lateral swaying due to three key factors: First, uneven load on the heavy object (such as center of gravity shift or sudden load changes) leads to an imbalance in the force on the wire rope; second, the impact of starting and stopping the lifting sling (such as the instantaneous tension during startup and the inertial force during shutdown) causes sudden shaking of the wire rope; and third, environmental interference (such as wind speed in outdoor operations and airflow disturbances in indoor operations) exacerbates the swaying amplitude of the wire rope. This swaying increases the risk of collisions between materials and surrounding equipment and structures, and may even cause safety accidents such as heavy objects falling.

[0003] To solve the problem of wire swaying, a technical solution of fixed guide wheels is usually adopted. Specifically, fixed guide wheels are set on the top of the lifting device to limit the wire swaying. However, they can only play a basic guiding role and cannot buffer the impact of swaying. The swaying energy is difficult to attenuate, and small swaying will continue to exist.

[0004] Therefore, it is necessary to provide a new stabilizing mechanism for vertical lifting devices to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a stabilizing mechanism for vertical lifting devices.

[0006] The stabilizing mechanism for vertical lifting devices provided by this utility model includes a U-shaped plate. Side plates are fixedly installed on both sides of the U-shaped plate, and each side plate is equipped with a sway-reducing component for lowering the swing of the lifting device's steel wire.

[0007] The swing lowering component includes a guide wheel, and coaxial mounting shafts are fixedly installed on both sides of the guide wheel. Each mounting shaft is fitted with a rotating arm and a pushing arm that are rotatably connected. The other end of the two rotating arms is mounted with a rotatably connected mounting bracket, and the mounting bracket is fixedly installed on the side plate. The other end of the two pushing arms is mounted with a buffer assembly.

[0008] Preferably, the buffer assembly includes a fixed frame, which is fixedly installed on the side plate, and a vertically arranged hydraulic damping rod is fixedly installed on the fixed frame. A connector is fixedly installed at the output end of the hydraulic damping rod, and a rotating rod is fixedly connected to the connector. Two push arms are respectively sleeved on the two ends of the rotating rod and rotatably connected to the rotating rod.

[0009] A spring is installed on the hydraulic damping rod.

[0010] Preferably, the spring is sleeved on the piston rod of the hydraulic damping rod.

[0011] Preferably, one end of the spring is fixedly connected to the upper end face of the hydraulic damping rod cylinder, and the other end of the spring is fixedly connected to the inner end face of the connector.

[0012] Preferably, the rotating arm and the pushing arm have a V-shaped structure, and the arm length of the pushing arm is greater than the arm length of the rotating arm.

[0013] Preferably, the guide wheels in the two sets of swing-down components are arranged opposite to each other, and the gap between the two guide wheels forms a wire guide channel structure.

[0014] Preferably, the U-shaped plate has multiple mounting holes.

[0015] Compared with related technologies, the stabilizing mechanism for vertical lifting devices provided by this utility model has the following advantages:

[0016] Beneficial effects:

[0017] When the lifting cable swings to one side, the guide wheel on that side is subjected to the counterforce of the cable and rotates about the mounting shaft as the deflection axis and toward the side plate. As a result, the push arm can press against the hydraulic damping rod. Therefore, the hydraulic damping rod, together with the spring, effectively reduces the swing amplitude of the cable and improves the stability of the lifting device during lifting.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 3 The present invention provides a stabilizing mechanism for a vertical lifting device, which includes a U-shaped plate 1 and a swing component 2.

[0025] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 Side plates 11 are fixedly installed on both sides of the U-shaped plate 1, and multiple mounting holes 1a are provided on the U-shaped plate 1. Each side plate 11 is equipped with a swing-lowering component 2 for lowering the lifting wire.

[0026] The lowering pendulum component 2 includes a guide wheel 21. Both sides of the guide wheel 21 are fixedly mounted with coaxially arranged mounting shafts 211. Each mounting shaft 211 is fitted with a rotatably connected rotating arm 22 and a pushing arm 23. The other end of the two rotating arms 22 is supported by a rotatably connected mounting bracket 221, which is fixedly mounted on the side plate 11. The other end of the two pushing arms 23 is supported by a buffer assembly 24. The buffer assembly 24 includes a fixing bracket 241, which is fixedly mounted on the side plate 11. A vertically arranged hydraulic damping rod 242 is fixedly mounted on the fixing bracket 241. The output end of the hydraulic damping rod 242 is fixedly mounted with... The connector 243 is fitted with a rotating rod 2431 that is fixedly connected to it. Two push arms 23 are respectively sleeved on the two ends of the rotating rod 2431 and rotatably connected to the rotating rod 2431. A spring 244 is installed on the hydraulic damping rod 242. Specifically, the spring 244 is sleeved on the piston rod of the hydraulic damping rod 242, and one end of the spring 244 is fixedly connected to the upper end face of the cylinder of the hydraulic damping rod 242, and the other end of the spring 244 is fixedly connected to the inner end face of the connector 243. The guide wheels 21 in the two sets of swing components 2 are arranged opposite to each other, and the gap between the two guide wheels 21 forms a steel wire guide channel structure.

[0027] It should be noted that: the U-shaped plate 1 is fixed to the top support of the vertical crane, maintaining the gap between the two guide wheels 21 to form a wire guide channel structure that is consistent with the lifting direction of the lifting wire, and the lifting wire is passed through the wire guide channel structure (as shown in the attached diagram). Figure 3As shown), the wire guide channel structure formed by the gap between the two guide wheels 21 can accurately guide the wire of the lifting device, ensuring that the wire always rises and falls along the preset path. At the same time, the guide wheel 21 can rotate adaptively with the swing of the wire, converting sliding friction into rolling friction, reducing the wear of the wire and the guide wheel 21, and extending the service life of both.

[0028] When the lifting cable swings to one side, the guide wheel 21 on that side is subjected to the resistance force of the cable and rotates about the mounting shaft 211 as the deflection axis and toward the side plate 11. As a result, the push arm 23 presses against the hydraulic damping rod 242. Therefore, the hydraulic damping rod 242, together with the spring 244, effectively reduces the swing amplitude of the cable and improves the stability of the lifting device during lifting.

[0029] Among them, the swing lowering component 2 adopts a combined buffer structure of hydraulic damping rod 242 and spring 244. Spring 244 can quickly absorb the initial impact force of the steel wire swing, avoiding the impact force from being directly transmitted to the mechanism body; hydraulic damping rod 242 slowly releases the absorbed energy through damping, effectively offsetting the rebound force of spring 244, avoiding the hidden danger of secondary swing from the root, and greatly improving the stability of the lifting device operation.

[0030] Furthermore, the rotating arm 22 and the pushing arm 23 have a V-shaped structure, and the arm length of the pushing arm 23 is greater than that of the rotating arm 22. This design can "amplify and transmit" the swing impact force received by the guide wheel 21 to the buffer assembly 24. Even when facing small swings, the hydraulic damping rod 242 and the spring 244 can respond quickly. The buffer assembly 24 is sensitive to small swings, achieving the effect of quickly suppressing small swings and efficiently buffering large swings.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
