Upwardly-walking concrete conveying device

Abstract

The invention discloses an upwardly-walking concrete conveying device. The upwardly-walking concrete conveying device helps the defect that a large gap is kept between a guide wheel and a guide rail.Axes of four groups of guide wheels are horizontally arranged on a track. Through arrangement of a guide suspension bracket, the guide wheels rotate at 360 degrees. During turning, the guide wheels are always attached to the track so that an overall device can be fully positioned to the track. The overall device is prevented from deviating in order to reduce walking resistance. After turning, theguide wheels are restored and move straightly through a straightening mechanism. Therefore, hunting motion is prevented. The device adopts the structural form of elastic suspension. Elastic damping parts are arranged between the overall device and all walking mechanisms such that the overall device can be elastically hung on the track. During the travelling process of the overall device, the device is prevented from jolting caused by the uneven track. The device travels smoothly and steadily, thereby reducing impact on the track. The walking speed increases.

Description

technical field [0001] The invention relates to the field of concrete conveying devices, in particular to an upward traveling concrete conveying 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] The existing conveying materials are divided into two types: up-running and down-running. [0004] For example, a transport hopper driven by a tractor trolley disclosed in Chinese utility model patent ZL201520465252.1, and a precast concrete transport vehicle disclosed in Chinese invention patent ZL201010161137.7, both of which have a downward traveling structure. The remarkable feature of the down-travel structure is that a tractor is needed to pull the hopper forward, and a connecting rod (or coupling) is required to be hinged between the t...

AI Technical Summary

Problems solved by technology

The disadvantage is that in the upward traveling structure, the axis of the guide wheels is set vertically, which is constrained by four sets of guide wheels installed on the running track. Since it needs to pass through the curve, there must be enough clearance between the guide wheels and the track, otherwise it will be blocked. Stuck, due to the existence of this large gap, the body is deflected relative to the track during the running process, the running resistance is large, the noise is large, and due to the deflection of the body, an angle appears in the direction of movement of the trolley line, which reduces the life of the trolley line and reliability

[0006] Whether it is the upper running or lower running structure, there is a defect that the wheel and the body are connected by a rigid bearing seat, which has a large impact on the track and is not conducive to increasing the running speed.
