Special trolley suitable for diversion tunnel large-diameter pressure pipeline

Abstract

The invention provides a special trolley suitable for a diversion tunnel large-diameter pressure pipeline, and belongs to the technical field of transportation equipment. The trolley is used for solving the problems of difficult transportation and installation of large-diameter pressure pipelines in a tunnel. The trolley comprises a traveling system, a main beam, a support system, a hydraulic system, and an electrical control system, the traveling system comprises a traveling wheel set, a hydraulic motor and a support platform, the left side of the support platform is provided with a counterweight system, the support system comprises a support frame, a support frame traveling mechanism, horizontal support arms and longitudinal support arm, the main beam is fixedly provided with a support frame travelling hydraulic cylinder, the telescopic end of the support frame travelling hydraulic cylinder is fixedly connected with the support frame travelling mechanism, the horizontal support armsare symmetrically distributed on the left and right sides of the support frame, and the longitudinal support arm is vertically arranged above the support arms. The trolley can realize transportation,adjustment, and installation in place of a pressure steel pipe in the tunnel, is suitable for the loading requirements of pipelines of different sizes, is strong in adjustability, and greatly improvesthe construction efficiency and quality.

Description

technical field [0001] The invention belongs to the technical field of transportation equipment, and relates to pipeline transportation equipment, in particular to a special trolley suitable for large-diameter pressure pipelines in water diversion tunnels. Background technique [0002] The diversion tunnel is a hydraulic tunnel that diverts water from the water source, and is divided into a pressure diversion tunnel and a non-pressure diversion tunnel. The pressure diversion tunnel is an underground water delivery structure connecting the shore-type pressurized water inlet of the hydropower station and the surge chamber (or the pressure pipe of the hydropower station without a surge chamber). The pressure diversion tunnel generally adopts a circular cross section. In order to prevent rock collapse and water seepage, reinforced concrete is often used as a permanent lining for the tunnel body, and pressure pipes are arranged inside the tunnel segment lining. The pressure pipes...

AI Technical Summary

Problems solved by technology

[0003] During the construction of the water diversion tunnel, due to the lining of the tunnel segment, the distance between the outer wall of the penstock and the inner diameter of the concrete segment is very small, that is, the transportation and operation space of the penstock in the tunnel is narrow, and the transportation and installation are difficult. The conventional flat trolley Transportation or gantry electric hoist transportation cannot be realized. Therefore, a special trolley suitable for transportation and installation in large-diameter pressure pipes in diversion tunnels must be designed.
