Tower crane trolley limiting device

Abstract

The invention discloses a tower crane trolley limiting device. The tower crane trolley limiting device comprises a bracket, a sliding rail, a slider, a fixed base, a lifting hook, a protective device,a solar device, a storage battery and a warning device; the sliding rail is fixedly installed inside the bracket; the slider is slidably connected to the inside of the sliding rail; the fixed base isfixedly installed at the lower end of the slider; the lifting hook is fixedly installed at the lower end of the fixed base; and the protective device is fixedly installed at the two sides of the fixed base and the inner wall of the bracket. According to the tower crane trolley limiting device provided by the invention, by arranging the solar device, the angle of the solar panel can be adjusted atwill according to the angle of sunlight, so as to achieve the maximum power generation, so that the limiting device has the function of solar power generation, and the power generation is sufficient;and by arranging the protective device, the protection of the bracket is achieved, and the influence on the service life and stability of the limiting device caused by rigid impact on the bracket inthe movement process of the lifting hook is avoided.

Description

technical field [0001] The invention relates to a tower crane device, in particular to a tower crane trolley limiting device. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and transports heavy objects horizontally within a certain range. With limit device. [0003] The existing limit device does not have a device for solar power generation, so the electricity required for the use of the alarm is connected from the crane, resulting in a waste of resources and needs to be improved; [0004] Moreover, the hook in the limit device is prone to rigid impact with the support during the movement process, which affects the service life and stability. Contents of the invention [0005] The object of the present invention is to provide a trolley limiting device for a tower crane to solve the problems raised in the above-mentioned background technology. [0006] To achieve the above object, the present invention provides the f...
