Embodiment Construction

[0029] In order to further understand the content, characteristics and efficacy of the invention, the following examples are given for detailed description.

[0030] See Figure 1 , the safe cantilever crane column 1 and the crane host of the invention are provided with a rotary driving device 2 between the column 1 and the crane host. Among them, the column 1 is used for support, so that the crane host is at a certain height position, and the cantilever crane is installed and fixed at a specific position. The rotary driving device 2 is used to drive the crane host to rotate and move, so as to adjust the lifting position.

[0031] Column 1 is made of thick wall metal pipe, and flange plates are set at the top and bottom. The flange plates at the bottom are installed and fixed with strong bolts, such as fixed on the platform of wind power facilities or the deck of ship facilities.

[0032] See Figure 2 、 Figure 3 and Figure 5 It can be seen that the crane host includes the host hous...

Abstract

The invention relates to a safe cantilever crane. Comprising a stand column and a crane host, and a rotation driving device is installed between the stand column and the crane host. The crane main machine comprises a main machine shell, a steel wire rope reel is installed in the main machine shell, a driving assembly for driving the steel wire rope reel is installed on the side portion of the main machine shell, an inclined cantilever is further installed on the main machine shell, an end rope wheel is installed at the outer end of the cantilever, and an end platform is installed below the end of the cantilever. A guide wheel assembly is installed in the end platform, a steel wire rope wound and unwound by the steel wire rope reel penetrates through the guide wheel assembly, a contact switch used for detecting a hanging assembly at the end of the steel wire rope is further installed on the end platform, and a tensioning detection assembly used for detecting the tensioning state of the steel wire rope is installed in the main machine shell. A stroke measuring assembly is further installed on the side portion of the main machine shell, and a corner limiting assembly is installed between the bottom of the main machine shell and the top of the stand column. The cantilever crane is compact in structure and high in safe operation control capacity.

Description

technical field [0001] The invention belongs to the technical field of lifting equipment, in particular to a safe cantilever crane. Background technology [0002] The cantilever crane is a kind of important hoisting equipment used in modern production and construction engineering. Structurally, the cantilever crane is composed of column, slewing device and steel wire rope driving device. The hook assembly is installed at the end of the steel wire rope. During operation, the slewing device controls the rotation of the whole machine to find the position of the articles to be hoisted. The steel wire rope driving device drives the steel wire rope to move up and down, and the articles suspended on the hook are lifted and lowered, which cooperate with the rotation driving function provided by the driving device to realize the hoisting and transfer of articles. [0003] The cantilever is widely used in the field of moving goods on the deck, such as the cantilever crane, which is widely ...
