Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipe caulking, in particular to a drainage pipe caulking rotating mechanism. 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, facing great danger; 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. 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 rotary mechanism for grouting in a drainage pipe comprises a connecting bracket, wherein the connecting bracket comprises a connecting cross plate, and a first electric push rod is embedded in the left and right sides of the connecting cross plate, and a rubber storage tube is sleeved on the outer end of the first telescopic rod 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, a connecting plate is provided between the upper end of the sliding block and the two rubber storage tubes, and the connecting plate, the sliding block and the rubber storage tube are all hinged.

[0008] A telescopic mechanism is installed inside the sliding track; the telescopic mechanism includes a second electric push rod, which includes a shell and a telescopic rod. The outer end of the shell 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] The transverse plate is fixedly connected to a rotating gear, the rotating gear is meshed with a driving gear, the driving gear is transmission-connected to the power output end of the second driving motor, and the rotating gear is connected to the rotating shaft.

[0010] As a preferred solution, each of the first electric push rods is connected to a driving motor.

[0011] Compared with the prior art, the utility model has the following beneficial effects: 1. By setting the second driving motor to rotate, the driving gear drives the rotating gear to rotate, and then the horizontal plate drives the two first electric push rods, the two rubber storage tubes and the rotating disk to rotate, and then the extension of the two first electric push rods makes the grouting glue inside the two rubber storage tubes spray out from the rubber outlet tube 7 and smear on the inner wall of the drain pipe, so that the grouting can be automatically performed without manual work;

[0012] 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 first electric push rods on both sides. At this time, the joint glue can be conveniently added to the inside of the glue storage tube. When the extended length of the first electric push rod cannot squeeze out the joint glue inside the glue storage tube, the second electric push rod can be extended so that the joint glue inside the glue storage tube can be completely squeezed out.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0018] A rotary mechanism for grouting in a drainage pipe comprises a connecting bracket 1, wherein the connecting bracket 1 comprises a connecting transverse plate 2, wherein first electric push rods 3 are respectively embedded on the left and right sides of the connecting transverse plate 2, wherein a rubber storage tube 5 is sleeved on the outer end of a first telescopic rod 4 of each of the first electric push rods 3, wherein the end of the rubber storage tube 5 is fixedly connected to a rotating disk 6, wherein an outer wall of the rotating disk 6 is connected to a rubber outlet tube 7 corresponding to the rubber storage tube 5, wherein a rubber outlet port 71 of one of the rubber outlet tubes 7 is arranged upward, and a rubber outlet port 71 of the other of the rubber outlet tubes 7 is arranged downward.

[0019] Furthermore, each of the first electric push rods 3 is connected to a driving motor 17 .

[0020] The glue outlet pipe 7 sprays out the caulking glue and the inner wall of the drain pipe can be caulked by the rotation of the rotating disk 6.

[0021] A sliding track 8 is provided between the two first electric push rods 3, one end of the sliding track 8 is fixedly connected to the rotating disk 6, a sliding block 9 is installed inside the sliding track 8, and a connecting plate 10 is provided between the upper end of the sliding block 9 and the two rubber storage tubes 5, and the connecting plate 10 is hinged to the sliding block 9 and the rubber storage tube 5.

[0022] A telescopic mechanism 11 is installed inside the sliding track 8 .

[0023] The telescopic mechanism 11 includes a second electric push rod 12, which includes a shell 121 and a telescopic rod 122. The outer end of the shell 121 is fixedly connected to the inner wall of the sliding track 8 close to the rotating disk 6, and the telescopic end of the telescopic rod 122 is connected to the sliding block.

[0024] The transverse plate 2 is fixedly connected to a rotating gear 13 , and the rotating gear 13 is meshed with a driving gear 14 . The driving gear 14 is transmission-connected to a power output end of a second driving motor 15 , and the rotating gear 13 is connected to a rotating shaft 16 .

[0025] The second driving motor 15 rotates so that the driving gear 14 drives the rotating gear 13 to rotate, and then the horizontal plate 2 drives the two first electric push rods 3, the two rubber storage pipes 5 and the rotating disk 6 to rotate, and then the extension of the two first electric push rods 3 makes the joint glue inside the two rubber storage pipes 5 spray out from the rubber outlet pipes 7 and smear on the inner wall of the drain pipe. The glue outlet 71 of one of the rubber outlet pipes 7 is set upward, and the glue outlet 71 of the other rubber outlet pipe 7 is set downward; in this way, when the rotating disk 6 rotates half a circle, the two rubber outlet pipes 7 can evenly smear the joint glue on the inner wall of the drain pipe.

[0026] By setting the connecting plates 10 on both sides, the installation of the rotating disk 6 and the glue storage tube 7 can be made more stable, and the rotating disk 6 can be moved forward by extending the second electric push rod 12 to drive the two glue storage tubes 5 to detach from the telescopic ends of the two first electric push rods 3. At this time, the joint glue can be conveniently added to the inside of the glue storage tube 7. When there is an obstacle inside the drainage pipe that prevents the robot from moving, the rotating disk 6 can push the obstacle away by extending the second electric push rod 12. When the first electric push rod 3 is extended to a length that cannot squeeze out the joint glue inside the glue storage tube 5, the second electric push rod 12 can be extended so that the joint glue inside the glue storage tube 5 can be completely squeezed out.
