Self-running apparatus of pier-crossing suspension bracket

Abstract

The invention relates to a self-running apparatus of a pier-crossing suspension bracket. The self-running apparatus comprises self-running dollies and a suspension bracket that is suspended by the self-running dollies by steel wire ropes. The self-running dollies are provided with self-driven systems; the self-driven systems include rollers arranged at the bottoms of the self-running dollies and drive motors arranged inside the self-running dollies; and the drive motors are connected with the rollers by transmission mechanisms. The suspension bracket is suspended by at least two self-running dollies by using the steel wire ropes. The self-running dollies are provided with frame bodies and a plurality of stretchable telescopic arms arranged at the tops of the frame bodies; the front ends of the telescopic arms extend out of one sides of the frame bodies; fault detection sensors and automatic telescopic control apparatuses are arranged at the telescopic arms; and hooking parts are arranged at the front ends of the telescopic arms and the suspension bracket is suspended at the hooking parts by steel wire ropes. Besides, winding engines are arranged inside the frame bodies and control the suspension bracket to move up and down by the steel wire ropes. The self-running apparatus has the following beneficial effects: the structure is simple; the manufacturing cost is low; consumed time for pier crossing or pole crossing is short; the construction efficiency is improved; and the applicability and flexibility are high.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to a self-propelled device for a pier-span hanger. Background technique [0002] The hanger equipment is a suspension machine that can be lifted vertically. Through the hanger equipment, the staff can reach all facades for construction. It is mainly used for cleaning and maintenance of the outer windows and outer walls of ships, buildings or structures. The suspension control space of hanger equipment including hanger and suspension hanger mainly depends on the suspension control equipment. However, because the suspension equipment needs to rely on the track to move, and the existing suspension control equipment has a complex structure and high cost, the application of the hanger has great limitations.

Problems solved by technology

[0002] The hanger equipment is a suspension machine that can be lifted vertically. Through the hanger equipment, the staff can reach all facades for construction. It is mainly used for cleaning and maintenance of the outer windows and outer walls of ships, buildings or structures. The suspension control space of hanger equipment including hanger and suspension hanger mainly depends on the suspension control equipment. However, because the suspension equipment needs to rely on the track to move, and the existing suspension control equipment has a complex structure and high cost, the application of the hanger has great limitations

In recent years, hangers are widely used in the construction or cleaning of large-scale cross-river and sea-crossing bridges. The hangers are suspended by cranes or other suspension control machinery to allow construction personnel to reach the various facades of the bridge and carry out construction work on the bridge. When the hanger is constructed on the bottom of the bridge, since the bottom of the bridge is provided with supporting piers, the piers divide the bridge into several spans. When one span is completed and moved to the next span, the existing hanger generally has to move The frame is lifted to the bridge deck to be separated and dismantled from the crane or suspension machinery, transferred to the next span and then assembled and suspended to the bottom of the bridge. This process is complicated, time-consuming, and extremely dangerous. hinder the progress of the project

[0003] In addition, when constructing the side of the bridge, when the crane or the suspension machine moves laterally on the bridge surface, the lamp posts or utility poles set on the bridge surface will hinder the steel wire ropes used for suspension, so that the hanger cannot be moved quickly. To move horizontally, the hanger needs to be hoisted, and the crane or suspension machinery is used to move on the bridge surface to realize the crossing of the utility poles, etc. The crane or suspension equipment is bulky and occupies a large area of ​​the bridge surface, causing great damage. Inconvenient and time-consuming to move, which greatly reduces the efficiency of construction
