Downwardly-walking concrete conveying device

Abstract

The invention discloses a downwardly-walking concrete conveying device. The device comprises a guide rail, a walking rack, a traction trolley and a rotary hopper. The traction trolley is connected with the front end of the walking rack through a coupler and used for traction of the walking rack along the guide rail. The rotary hopper is installed on the walking rack. The device has a structural form of elastic suspension. Therefore, bumping caused by the uneven rail is avoided. The device walks smoothly. Impact on the track is reduced, which is conducive to increasing walking speed. 4 groups of hanging brackets and elastic bodies are arranged in a cooperating manner such that the overall trolley can be fully positioned on the guide rail. The overall trolley does not deviate and compensatefor track gauge errors. Increase in running resistance is avoided and running stagnation is avoided. Due to reliable stability of operation of a trolley body, a novel slide wire installing mode is used. The included angle formed between the running direction of an electric brush of a current collector and a slide wire is close to 0 degree. Therefore, reliability and service lifetime of the slide wire are improved.

Description

technical field [0001] The invention relates to the field of concrete delivery devices, in particular to a down-running concrete delivery device. Background technique [0002] At present, in the industrial production of prefabricated components in the field of construction, a transport hopper with a power source is generally used to transport concrete between the concrete mixing station and the concrete placing machine. [0003] A prefabricated concrete transport vehicle disclosed in Chinese invention patent ZL201010161137.7, the wheels and the body are connected by rigid bearing seats, which has a large impact on the track and is not conducive to increasing the running speed; and when the gauge control is not accurate enough during construction, or the hopper When entering a curve, the rigid suspension is difficult to adapt to the gauge error, resulting in increased movement resistance or even stuck, affecting the passing performance.
