Embodiment

[0049] This embodiment discloses the pre-assembly and installation method of the built-in compensation device for the catenary pendant of a modern tram, and makes targeted improvements in view of the construction characteristics of the compensation device for the catenary of urban trams. When describing the embodiments, the specific terms for engineering equipment included in the embodiments are explained first. The manual hoist is called a chain hoist, which is a kind of manual lifting machine that is easy to use and easy to carry. When the manual hoist lifts heavy objects upwards, it pulls the manual chain and hand chain wheel clockwise, and pulls it counterclockwise when it is lowered. Manual chain, the brake seat is separated from the brake pad, the ratchet is stationary under the action of the ratchet, and the five-tooth long shaft drives the lifting sprocket to run in the opposite direction, thereby lifting and lowering the heavy object smoothly.

Abstract

The invention discloses a pre-assembly installation construction method for a balance weight built-in compensation device for an overhead line system of a modern tramcar. The pre-assembly installation construction method comprises the following steps: 1) firstly making preparations for construction; 2) installing an anchorage post at a preset position, conducting an anchor post pre-stress test; 3) installing and fixing an anchor bearing base on the anchorage post after the test; 4) pre-configuring a compensation rope; 5) installing a compensation pulley on the anchor bearing base; 6) adjusting the position of the compensation pulley, and arranging a built-in balance weight string; and 7) finally inspecting the installation quality of various parts. In the construction method, the prefabrication, the installation and the adjustment of the balance weight built-in compensation device for the overhead line system are integrated, no potential safety hazard is left, the construction efficiency is greatly improved, the progress of works is greatly accelerated, the repeated dispatching is avoided, and the construction cost is reduced. In the later operation period, the risk that a weight balance is stolen is reduced, and the maintenance cost is also lowered.

Description

technical field [0001] The invention relates to a construction method of a pre-assembled installation method for a built-in compensator for catenary drop tops of modern trams. Background technique [0002] Tram is a light rail transit vehicle driven by electricity and running on the track. Tram is a kind of public transportation, also known as streetcar, or tram for short, which belongs to a kind of train driven by electricity, also known as tram. But usually they all walk on the street, and the train has only a single section, up to five sections. In addition, some cable cars that run on urban tracks can also be counted as a type of streetcar. Since trams are driven by electricity, the vehicles do not emit exhaust gas, so they are a pollution-free and environmentally friendly means of transportation. Most of the existing trams are powered by the catenary on the top, and the catenary is in the electrified railway, and is erected in a "zigzag" shape along the sky above the...
