Auxiliary vacuumizing and automatic mud jacking integrated machine for railways

Abstract

The invention discloses an auxiliary vacuumizing and automatic mud jacking integrated machine for railways. The auxiliary vacuumizing and automatic mud jacking integrated machine for railways comprises a rack, an automatic mud jacking system and a vacuumizing system, wherein the automatic mud jacking system and the vacuumizing system are arranged on the rack. The automatic mud jacking system comprises a feeding system, a high-speed and low-speed stirring system, a static weighing system, a mud jacking and pressure stabilizing system, an environmental protection dust removal system, an automatic control system, a data storage and transmission system, an equipment self-inspection system, a cleaning system and an alarm system. By means of the novel vacuumizing and automatic mud jacking integrated machine, the purpose of conducting vacuumizing and mud jacking work at the same end of a pipeline is achieved, one-key operation of the work is achieved by adopting the uniform central control system, operation control is simplified, the automatic operation and control degree of the vacuumizing and mud jacking work are improved, accurate feeding and weighing, stable and continuous mud jacking and controllable flow are achieved, plumpness of mud in the pipeline can be guaranteed, and the whole construction process is environmentally friendly and free of pollution.

Description

technical field

[0001] The invention belongs to the field of railway machinery, and in particular relates to a railway auxiliary vacuum automatic grouting integrated machine. Background technique

[0002] Railway grouting machines are mainly used for grouting prestressed pipelines in bridges. Pipeline grouting is one of the most important construction links in post-tensioned beams. At present, vacuum-assisted grouting technology is basically used. The currently commonly used grouting trolley lacks an automatic feeding weighing system or has defects such as inaccurate feeding and weighing, arbitrary slurry configuration, and long powder transmission stroke; the integration of equipment at both ends of the pipeline is not high, and manual intervention affects The degree of automation of the grouting operation is limited, resulting in complex grouting operations, unstable grouting process, easy residual air at the grouting end, resulting in unsatisfactory construction, and seri...

Embodiment 1

[0044] Such as Figure 6 As shown, the grouting end of the pipeline of the prestressed concrete beam is also provided with an air release pipe 33 . The slurry outlet end of the pipeline of the prestressed concrete beam is provided with a slurry outlet pipe 34 . The vacuum pipe 28, the air release pipe 33, and the grout outlet 29 are all sealed and connected to the pipes of the prestressed concrete beam, and the pipes are respectively provided with corresponding valves. The vacuuming and grouting process of embodiment one are as follows: check the valve situation of the pipeline of the prestressed concrete beam, ensure that the grouting outlet 29, the vacuum pipe 28, the air release pipe 33, and the grouting pipe 34 are all tightly connected with the pipeline, Form a sealed state, and the initial state of each valve is closed; open the valve of the vacuum tube 28 and start the vacuum pump 27 through the PLC assembly electric control box 30, and vacuumize the pipeline. When the...
