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.

Embodiment 1

[0044] see Figure 1-12 , this embodiment provides a special trolley suitable for large-diameter pressure pipes in diversion tunnels, including a traveling system 1, a main beam 2, a support system 3, a hydraulic system and an electrical control system. The traveling system 1 includes a traveling wheel set 101, Hydraulic motor 102 and supporting platform 103, the left side of supporting platform 103 is provided with counterweight system 4, the lower end of main beam 2 is fixed on supporting platform 103, and the supporting end of main beam 2 is positioned at the right side of supporting platform 103, supporting system 3 Including a support frame 301, a support frame traveling mechanism 302, a lateral support arm 303 and a longitudinal support arm 304, the support frame 301 is slidably arranged on the main beam 2, the main beam 2 is fixed with a support frame walking hydraulic cylinder 6, and the support frame walking hydraulic cylinder The telescoping end of 6 is fixedly conne...

Embodiment 2

[0057] The invention provides a special trolley suitable for large-diameter pressure pipes in water diversion tunnels. The special trolley for steel pipe transportation and installation can not only meet the transportation of a single steel pipe in the tunnel, but also can be used by two identical trolleys at the same time. , for transportation and installation of long-dimensioned, heavy-weight pipe fittings or paired installation units, such as Figure 13 and 14 As shown, through the cooperation of two trolleys, the transportation and installation work in the tunnel of the paired installation unit is realized.

[0058] Working principle of the present invention:

[0059] The special-purpose trolley drives the trolley to walk through the walking system 1, the support system 3 supports the pressure steel pipe 8, and adjusts the counterweight through the counterweight system 4 to meet the transportation of pipes with different weights. The hydraulic system cooperates with the e...

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...
