Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline seam filling, and in particular relates to a pipeline seam filling push-pull device. Background Art

[0002] In drainage engineering, whether the water-tightness test is passed is an important indicator to determine whether the drainage pipe construction is qualified. At present, the factors that lead to the failure of the pipeline water-tightness test are mostly quality problems at the interface of the drainage pipe, such as: the working surface of the pipe socket and the spigot is not flat, the rubber ring and the pipe spigot are not matched, the gap between the socket and the spigot is too large or the roundness of the socket and the spigot is inconsistent, or when the mouth is hit, the rubber ring is twisted due to uneven force, and the part is too loose or too tight, which may cause the flexible interface to be loose, thus causing the current interface to leak.

[0003] In the prior art, the commonly used treatment method is to fill the gap between the socket and the spigot inside the pipeline with waterproof caulking materials. Workers will enter a hidden space to work, which is very dangerous. At the same time, the recognized working surface inside the pipeline is very limited, and the quality of construction cannot be guaranteed at all. When encountering a pipeline with a relatively small diameter, workers will not be able to carry out internal construction work. The utility model discloses a push-pull glue discharging device when using mechanical caulking. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A push-pull device for grouting in a pipeline comprises a connecting transverse plate, wherein a first electric push rod is embedded in the left and right sides of the connecting transverse plate, a rubber storage tube is sleeved on the outside of each of the first electric push rods, and a rotating disk is fixedly connected to the end of the rubber storage tube, and a rubber outlet pipe corresponding to the rubber storage tube is connected to the outer wall of the rotating disk, wherein the rubber outlet of one of the rubber outlet pipes is arranged upward, and the rubber outlet of the other rubber outlet pipe is arranged downward.

[0007] A sliding track is provided between the two first electric push rods, one end of the sliding track is fixedly connected to the rotating disk, a sliding block is installed inside the sliding track, and a connecting plate is detachably connected between the upper end of the sliding block and the two rubber storage tubes; the connecting plate, the sliding block and the rubber storage tube are all hinged.

[0008] The sliding track is provided with a telescopic mechanism, which includes a second electric push rod, which includes a housing and a telescopic rod, wherein the outer end of the housing is fixedly connected to the inner wall of the sliding track near the rotating disk, and the telescopic end of the telescopic rod is fixedly connected to the sliding block.

[0009] As a preferred solution, each of the first electric push rods is connected to a driving motor.

[0010] Compared with the prior art, the utility model has the following beneficial effects: 1. The utility model extends the first electric push rod so that the grouting glue inside the glue storage pipes on both sides is sprayed out from the glue outlet pipes and smeared on the inner wall of the drain pipe, so that the grouting can be automatically performed without manual work;

[0011] 2. By extending the second electric push rod, the rotating disk moves forward and drives the glue storage tubes on both sides to detach from the telescopic ends of the two first electric push rods. At this time, the joint glue can be conveniently added to the inside of the glue storage tubes. When the extended length of the first electric push rod cannot squeeze out the joint glue inside the glue storage tubes, the second electric push rod can be extended so that the joint glue inside the glue storage tubes can be completely squeezed out.
