The invention discloses a pinion and rack controlled material conveying and lifting device for building construction. The pinion and rack controlled material conveying and lifting device comprises a pedestal; the left and right sides of the middle part of the upper portion of the pedestal are each fixedly connected with a fixing block; the middle part of the upper portion of each fixing block is connected with a sliding rod; the middle part of each sliding rod is externally connected with a slider in a contact manner; the middle part of the lower portion of each slider is connected with a spring in a contact manner; the upper end of each sliding rod is fixedly connected with a limiting block; the middle parts of the inner sides of the two sliders are each connected with a fixing connectingrod; a material box is connected between the fixing connecting rods; the middle parts of the outer sides of the two sliders are each connected with a second fixing rod; the middle part of the lower portion of each second fixing rod is connected with a connecting rod; the middle part of each connecting rod penetrates through a first fixing slider and is connected with the corresponding first fixing slider in a contact manner; the left side of the lower portion of each connecting rod is fixedly connected with a first fixing rod; the left end of each first fixing rod is connected with a rack; and pinion and rack controlled material conveying and lifting device is in axially-symmetrical connection. The pinion and rack controlled material conveying and lifting device disclosed by the inventionis quite stable and quite high in safety when being used for conveying goods and guarantees the safety of an operator in an operation process.
Description
technical field [0001] The invention relates to the field of construction machinery and equipment, in particular to a rack and pinion control material delivery and lifting device for construction. Background technique [0002] Construction machinery is the general term for machinery and equipment used in engineering construction and urban and rural construction. It is also called "construction machinery" and "construction machinery" in China. According to Chinese standards, construction machinery is divided into the following types: excavation machinery, shovel Transportation machinery, compaction machinery, engineering hoisting machinery, road machinery, concrete machinery, decoration machinery, high-altitude operation machinery, concrete product machinery, piling machinery, etc. Material transport lifting devices are an important part of construction machinery. It is very commonly used in building construction, and it is usually used to hoist building materials or construc...
