Wheeled crane and moveable counterweight component thereof

Abstract

The invention discloses a moveable counterweight component of a wheeled crane. The moveable counterweight component of the wheeled crane comprises a counterweight body (26) and a positioning mechanism, wherein the counterweight body (26) is arranged on a vehicle frame (21) of the wheeled crane through the positioning mechanism. The moveable counterweight component of the wheeled crane also comprises a guide mechanism, wherein the guide mechanism (22) further comprises a first guide part and a second guide part; the second guide part is connected with the first guide part in a sliding and detachable manner; the first guide part is arranged on the vehicle frame (21) and extends outwards relative to the vehicle frame (21); the second guide part is arranged on the outer surface of the counterweight body (26); and the sliding direction of the two guide parts is as same as the assembling direction of the counterweight body (26). The moveable counterweight component has short operating time during assembling, effectively avoids potential hazards to workers when the counterweight is arranged and guarantees labor safety. The invention also discloses the wheeled crane comprising the moveable counterweight component.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a movable counterweight assembly for a wheeled crane. The present invention also relates to a wheeled crane comprising the above movable counterweight assembly. Background technique [0002] With the rapid development of my country's economic construction, the market's demand for construction machinery, especially various cranes, is increasing. The increasing operating height and lifting tonnage of cranes make the crane's tipping moment larger during operation. , which brings many potential dangers to the lifting operation; in order to ensure the safety of the crane and avoid tipping when the crane is hoisted, it is necessary to install a counterweight on the crane frame. The counterweight is generally a block structure of cast iron material. When the crane When performing hoisting operations, it is hung at the tail of the crane, and the gravity moment of the counterweight is ...

AI Technical Summary

Problems solved by technology

[0006] The installation of the above-mentioned counterweight body is mainly based on the installation experience of the operator and the cooperation of the ground personnel. Due to the limitation of the field of view, the operator cannot see the counterweight positioning hole at the bottom of the movable counterweight and the counterweight on the frame. Whether the repositioning block is consistent can only be operated vaguely by feeling, and the positioning and placement of the movable counterweight needs to be completed through multiple trial installations, which makes the installation process of the counterweight body very time-consuming; at the same time, when placing the counterweight body During the process, due to the influence of the wind force and the inertia of the counterweight itself, the counterweight body will swing back and forth, making it difficult to accurately locate. According to the traditional placement method, manual coordination of ground personnel is generally required for positioning. Therefore, the entire installation The process has brought great safety hazards to the ground staff
