Trolley capable of conveniently quickly adjusting installing position of pressure steel pipe and achieving transportation of pressure steel pipe

Abstract

A trolley capable of conveniently quickly adjusting the installing position of a pressure steel pipe and achieving the transportation of the pressure steel pipe comprises a pressure steel pipe adjusting and installing device, device pressure steel pipe positioning and clamping devices, a trolley body, driving wheel running devices, driven wheel running devices, a hydraulic station device and a hydraulic motor device. The device pressure steel pipe positioning and clamping devices is arranged on the upper portion of the trolley body, the steel pipe is placed on the positioning and clamping device, and the pressure steel pipe adjusting and installing devices are used for alignment adjusting and installation of the steel pipe. The driving wheel running devices and the driven wheel running devices are arranged on the lower portion of the trolley body; the number of the driving wheel running devices is two in total, and the driving wheel running devices are arranged in an opposite angle mode; the number of the driven wheel running devices is two in total, and the driven wheel running devices are arranged in an opposite angle mode. The trolley can be installed and dismantled manually, follow-up positioning, installing and welding of the steel pipe are facilitated, and automatic centering adjusting and installation of the steel pipe can be achieved by controlling the adjusting and installing device after the steel pipe reaches the installation position.

Description

technical field [0001] The invention relates to a device for automatically adjusting the installation position and transportation of steel pipes, in particular to a trolley device for large-tonnage pressure steel pipes that needs to be adjusted and installed at the same time. Background technique [0002] Penstock is a widely used pressure relief device in engineering practice. With the continuous evolution of its performance, its use is becoming more and more extensive. Because of its high compression resistance, high corrosion resistance, quick and convenient installation, etc., it plays a key role in compression resistance and drainage to reduce potential energy loss in hydropower engineering projects. However, the transportation and adjustment and installation of penstocks in actual hydropower projects are easily restricted and constrained by factors such as construction environment, construction conditions, and construction costs. Coupled with the influence of the steel...

AI Technical Summary

Problems solved by technology

However, the transportation and adjustment and installation of penstocks in actual hydropower projects are easily restricted and constrained by factors such as construction environment, construction conditions, and construction costs. Coupled with the influence of the steel pipe's own weight, there are great difficulties in its transportation and installation. , so it is necessary to develop and design new devices for automatic adjustment, installation and transportation of penstocks

[0003] At present, although there are many transportation equipment for penstocks, most of them are used in the conditions of light weight, no need for adjustment and installation, and relatively sufficient transportation space. The construction conditions described above are not applicable. There is no device for automatic adjustment and transportation of penstocks at the same time
