Description
Technical Field
[0001] This utility model relates to the field of crane accessories, specifically a counterweight device for preventing crane swaying. Background Technology
[0002] In modern industrial production and infrastructure construction, cranes, as crucial material handling equipment, are widely used in various fields such as construction, ports, and heavy machinery manufacturing. With their powerful lifting capacity, they can efficiently complete the hoisting, transportation, and loading / unloading of heavy goods, greatly improving production efficiency and reducing labor costs. As industrial production scales and engineering construction complexities continue to expand, the requirements for cranes' lifting capacity, operational stability, and operational precision are becoming increasingly stringent. Cranes can efficiently complete the lifting, transportation, and loading / unloading of heavy goods, greatly improving production efficiency and reducing labor costs. With the continuous expansion of industrial production scale and the increase in engineering construction complexity, the requirements for the lifting capacity, working stability, and operation accuracy of cranes are becoming increasingly stringent. In the actual operation of cranes, due to the lifting, lowering, and lateral movement of goods, as well as the influence of external environmental factors, swaying is very likely to occur. Crane swaying not only leads to a decrease in the accuracy of loading and unloading goods and affects work efficiency, but may also cause serious safety accidents such as goods falling and crane overturning, resulting in significant economic losses and casualties. Therefore, a counterweight device for preventing crane swaying is needed.
[0003] An existing counterweight device for cranes cannot be fixed in place during operation, which easily leads to swaying. Furthermore, it cannot be adjusted by adding or removing counterweight modules according to different environmental requirements, making it inconvenient for splicing and operation. Therefore, there is an urgent need for a counterweight device for cranes to prevent swaying. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a counterweight device for preventing crane swaying, comprising a placement platform, a vertical rod installed at the upper end of the placement platform, a connecting rod installed at the upper end of the vertical rod, a counterweight module installed at the upper end of the placement platform, limit grooves formed at the upper and lower ends of the counterweight module, fixing holes formed at both the left and right ends of the counterweight module, threaded holes formed at both the left and right ends of the placement platform, a lifting plate installed at the upper end of the threaded holes, a fixing rod installed at one end of the lifting plate, a positioning rod installed at the front end of the lifting plate, a limit rod installed at one end of the counterweight module, and limit holes formed at both the left and right ends of the limit rod.
[0006] Preferably, the vertical rod is threadedly connected to the connecting rod, and the vertical rod is symmetrically arranged with respect to the central axis of the placement platform.
[0007] Preferably, the counterweight module is engaged with the placement platform via a vertical rod, and the counterweight module is in close contact with the placement platform.
[0008] Preferably, the lifting plate is threadedly connected to the placement platform through a threaded hole, and the lifting plate is symmetrically arranged with respect to the central axis of the placement platform.

This utility model, through the setting of a placement platform, vertical rod, connecting rod, counterweight module, lifting plate, fixing rod and positioning rod, can restrict and fix the position of the counterweight module from top to bottom through the vertical rod and connecting rod installed in the device. At the same time, the counterweight module can be fixed at both ends by limiting rod through the limiting grooves opened at the upper and lower ends, which can better fix the counterweight module from multiple aspects and prevent shaking.
[0012] 2. This utility model, through the setting of a placement platform, vertical rod, connecting rod, and counterweight module, allows the connecting rod installed in the device to be connected to the vertical rod by twisting. After connection, it can be spliced according to actual needs, and more counterweight modules can be installed, spliced, and assembled, making it convenient to add or remove counterweight modules and easy to use.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0019] The embodiments of this utility model will be described below based on its overall structure.
[0020] Please see Figures 1-4 A counterweight device for preventing crane swaying includes a platform 1, a vertical rod 2 mounted on the upper end of the platform 1, a connecting rod 3 mounted on the upper end of the vertical rod 2, and a counterweight module 4 mounted on the upper end of the platform 1. The vertical rod 2 and the connecting rod 3 are threadedly connected, and the vertical rod 2 is symmetrically arranged about the central axis of the platform 1. The connecting rod 3 is connected to the vertical rod 2 by a threaded connection, allowing for the addition and removal of the counterweight module 4 at different heights. Limiting grooves 5 are provided at the upper and lower ends of the counterweight module 4, and fixing holes 6 are provided at both the left and right ends of the counterweight module 4.
