Embodiment Construction

[0021] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] see figure 1 As shown, the present invention relates to a crane hoisting system for storing large stamping dies of automobiles, which includes a power supply 2, a motor 3, an inverter 4, an upper wire rope 5, a telescopic arm assembly 6, a lower wire rope 7, a support Disc 8 , rolling bearing 9 , connecting plate 10 , electric box 11 , rack 12 and balancer 13 .

[0023] Wherein each telescopic arm assembly 6 all comprises two telescopic arms, wherein one telescopic arm is accommodated in the other telescopic arm, and can carry out telescopic back-and-forth movement relative thereto to adjust the length of the entire telescopic arm assembly 6 . In this embodiment, there are 4 telescopic arm assemblies 6 arranged symmetrically in a cross. A power supply 2 , a motor 3 , an inverter 4 and an electric box 11 electrically connected are arra...

Abstract

The invention relates to a hoisting system of an overhead crane. The hoisting system comprises two or more support arms which are mutually connected and symmetrically arranged; the end part of each support arm is provided with a connecting plate; the upper parts of the connecting plates are connected with an upper wire rope and the lower parts are connected with a lower wire rope. The connecting mode between the connecting plates and the upper and the lower wire ropes allows the connecting plates and the upper and the lower wire ropes to be in the straight line when the lower wire rope is strained, so that the gravity of a load supported by the lower wire rope is directly acted on the lower wire rope, the connecting plates and the upper wire rope rather than the support arms. The hoisting system can reinforce the load bearing ability and be applied to a wider hosting range.

Description

technical field [0001] The invention relates to a crane hoisting system, in particular to a crane hoisting system used for hoisting large stamping dies of automobiles. Background technique [0002] Along with economic development, automobile has increasingly become a means of transportation for people to travel. In the domestic automobile market, with the rise of China's automobile industry and the development trend of more models and less batches, major domestic and international automobile companies are seizing the automobile market by increasing the launch of new models. [0003] In this general environment, while automobile companies increase the launch of new models every year, it will inevitably bring about a sharp expansion of the number of automobile molds, especially large stamping molds. At present, the large-scale stamping dies of domestic automobile companies are generally stored in two layers. Taking 60 sets of large-scale molds (side panels, four doors, two c...
