The crane is usually used for directly hoisting the butt joint at home, the method has the problems that the butt joint of the pipe joint is not in place, the joint seam between the pipe joints is not tight, the elevation and the axis deviation of the pipe do not meet the standard requirements, and the like, the water leakage phenomenon often occurs in the use process, the service life of the pipe is affected, the pavement is collapsed when serious, and the safety of pedestrians and driving is affected.

In addition, when laying buried pipelines, especially large-diameter concrete pipelines with a diameter of more than 1.2 meters, due to the large volume and heavy weight, a plurality of workers are required to cooperatively operate so as to splice the pipelines end to end. Because the annular stepped platforms for sealing and butting are respectively arranged at the two ends of the pipeline, the butting process is very tedious and inconvenient, at least 5-6 workers are required to continuously and slowly pry the pipeline to move and axially butt, the working efficiency is very slow, and the engineering progress is influenced.

the driving part is fixedly arranged on the fixed seat; the first cross beam facing the direction of the pipeline is fixedly arranged on the fixed seat, and is arranged along the diameter direction of the pipeline and is propped against the port of the pipeline;

the pushing part is fixedly arranged on a movable seat with universal wheels; at least one pull ring is arranged on one side of the pushing part facing the direction of the pipeline;

the driving end of the driving part is connected with the hook through a rope, and the hook is hooked with the pull ring; the pushing component drives the pipeline to move towards the driving component under the driving of the driving component.

Further, the driving part is a hoist.

Further, a variable frequency rotating speed switch and a tension meter are arranged on the winch.

Further, the pushing component is a second cross beam.

Further, the length of the first cross beam and the second cross beam is larger than the outer diameter of the pipeline.

Further, two pull rings are arranged on the pushing component.

The utility model has simple and reasonable structure and low manufacturing cost. The hoist engine is installed on the fixing base, the anchor pier is not required to be built on site, the pulling force of the hoist engine when winding the rope is in the opposite direction, the butt joint in the axial direction can be realized between the pipelines, the manual prying and lifting of a plurality of people are not required, and the operation is more convenient and labor-saving.

The prefabricated integrated pipe sleeper layer can reduce the deflection of the pipeline and ensure the pipeline to move in the axial direction; when the rope is installed, the gravity center of the rope can be arranged at 1/3 of the lower part of the pipeline so as to reduce the resistance during the pulling process; the two pull rings are arranged to disperse the pulling force to two sides, so that the axial movement of the pipeline is more facilitated and the pipeline cannot deviate; the fixed seat can be additionally provided with a moving wheel for convenient transportation; the winding engine is provided with a variable frequency rotating speed switch and a tension meter, so that the tightening speed and the tension of the steel wire rope during internal pulling are controlled, and the operation is more accurate and convenient.

Detailed Description

Referring to fig. 1 to 5, the utility model relates to a pull-in installation device of a large-diameter concrete pipeline winch, which comprises a driving part and a pushing part which are respectively arranged at two axial ends of a pipeline;

the driving part is fixedly arranged on the fixed seat; the first cross beam towards the direction of the pipeline is fixedly arranged on the fixed seat, and is arranged along the diameter direction of the pipeline and is propped against the port of the pipeline;

Further, the driving part is a hoist.

Further, the pushing component is a second cross beam.

Further, two pull rings are arranged on the pushing component.

The construction method of the utility model comprises the following steps:

step a, excavating a groove for laying a pipeline and checking whether the groove is qualified;

b, paving a small amount of fine sand at the bottom of the groove for leveling, and installing a prefabricated integrated pipe pillow cushion layer;
