Problems solved by technology

The traditional method of installing screen cabinets is to move the screen cabinets with crowbars or by shoulders or people. However, in actual work, most screen cabinets, such as station power distribution cabinets, are of high quality. It can reach 500-600kg. Therefore, it is very time-consuming and labor-intensive to use the above-mentioned traditional installation method. It is difficult to adjust the screen cabinet and the installation efficiency is low, resulting in increased workload and high risk.

Embodiment Construction

[0008] The universal mobile crane according to the present invention consists of three main parts: beam 1, support 2 and base 3, and the joints of the three parts can be fixed by screws. On the top of the row suspension, the crossbeam 1 is connected with the support 2 with the upper inclined support 4, and screws can be installed at the joint to fix it. At the bottom of the row crane, the base 3 is connected to the support 2 with the lower inclined support 5, and screws can be installed at the connection. Four universal wheels 6 are installed on the hanging base 3, and are fixed on the bottom of the base 3 by screw mounting screws, caster brakes 7 are installed on the universal wheels 6, and the advance and stop of the hanging are controlled with the caster brakes 7. Using the principle of triangular stability, install a pair of universal wheels with disc brakes on the diagonal of the quadrilateral formed by the base, and install ordinary universal wheels on the other diagonal...

Abstract

The invention provides a hoist capable of moving universally. The hoist is composed of a cross beam, supports and bases. The joints between the cross beam, the supports and the bases are fixed through screws. Each support is connected with the cross beam through an upper slanting support on the top of the hoist. The bases are connected with the supports through two lower slanting supports at the bottom of the hoist. Four universal wheels are installed on the bases of the hoist, and the joints between the four universal wheels and the bases are fixed through screws. Wheel brakes are installed on the universal wheels and are used for controlling forwarding and stopping of the hoist through disc brakes. A hanging ring is welded to the cross beam of the hoist. When the hoist is used, a hoist hook of a chain block is hung on the hanging ring, and then a screen cabinet can be ascended and descended. The hoist capable of moving universally is easy to operate and high in universality and the hoist can be operated by fewer workers.

Description

technical field [0001] The invention relates to a mobile crane for a mobile substation panel cabinet specially used in the electric power industry, specifically a mobile crane capable of universal movement. Background technique [0002] Screen cabinet installation is an important work in the power system. When carrying out this work, it is necessary to first place the screen cabinet at the designated position and adjust it. After marking the drilling position of the anchor screws, remove the screen cabinet for drilling and tapping. Finally, move the screen cabinet to the set position again. position, that is, reinstall the screen cabinet after tapping the wire. It can be known from the above installation process that moving the screen cabinet is an indispensable and important link in the installation of the screen cabinet. The traditional method of installing screen cabinets is to move the screen cabinets with crowbars or by shoulders or people. However, in actual work, m...
