Semi-self-walking penstock mounting system and method

Abstract

The invention discloses a semi-self-walking penstock mounting system and method, and relates to the technical field of penstock mounting of water diversion engineering. The system comprises a lifting station, a traction machine, a penstock conveying system and a penstock erecting system. The penstock conveying system comprises a conveying rail and a penstock conveying vehicle arranged on the conveying rail; one end of the penstock conveying vehicle is connected with the traction machine; the penstock erecting system comprises a penstock erecting rail, a penstock erecting machine arranged on the penstock erecting rail and a rail traction mechanism; the end, close to the slope top end, of the penstock erecting machine is connected with the end, close to the slope top end, of the penstock erecting rail through an iron chain; the rail traction mechanism is a penstock conveying vehicle or a chain block; and self-walking of the penstock erecting machine or the whole of the penstock erecting machine and the penstock erecting rail is realized through the rail traction mechanism. The penstock erecting machine and the penstock conveying vehicle are designed in a separated mode, so that penstock conveying and penstock erecting operation can be conducted at the same time, and the working efficiency is improved; the penstock erecting machine can realize a self-walking function on a slope section within a certain range; and multiple parallel pipelines can be mounted at the same time.

Description

technical field [0001] The invention relates to the technical field of penstock installation in water diversion projects, in particular to a semi-self-propelled penstock installation system and method. Background technique [0002] Water diversion projects generally have complex terrain and large gradient changes. The existing penstock installation methods all adopt the method of setting anchor points in front and pulling the portal frame through the traction mechanism; the existing methods have the following problems: 1. figure 1 As shown, the gantry under the existing installation method is all integrated design. The installation of the gantry generally lifts the steel pipe at the lifting station, and the steel pipe is carried by the tractor to the design position for installation. This transportation and installation use the same set of equipment , low efficiency; 2, such as figure 2 As shown, the existing penstock installation method can only install steel pipes on a s...

Problems solved by technology

[0002] Water diversion projects generally have complex terrain and large gradient changes. The existing penstock installation methods all adopt the method of setting anchor points in front and pulling the portal frame through the traction mechanism; the existing methods have the following problems: 1. figure 1 As shown, the gantry under the existing installation method is all integrated design. The installation of the gantry generally lifts the steel pipe at the lifting station, and then walks the steel pipe to the design position through the tractor for installation. This transportation and installation use the same set of equipment , low efficiency; 2, such as figure 2 As shown, the existing penstock installation method can only install steel pipes on a single pipe; the installation of penstocks with multiple rows of penstocks side by side requires multiple tracks and multiple portal frames to meet the construction requirements; 3. The existing penstock installation equipment None of them have automatic running function, and must rely on the front traction device for walking
