Description

Technical Field

[0001] The invention relates to the technical field of grouting and glue injection tools, and in particular to a replaceable glue injection device. Background Art

[0002] In the field of modern pipeline engineering, whether it is the construction of new pipelines or the maintenance and repair of pipelines already in use, it is crucial to ensure the integrity and functionality of the pipelines. There may be gaps at the joints of the pipelines, or due to various reasons such as material aging, corrosion, mechanical damage, construction quality, etc., the pipelines may have gaps, cracks, holes and other defects.

[0003] These defects not only affect the normal transportation function of the pipeline, leading to fluid leakage, causing resource waste and environmental pollution, but may also cause serious safety hazards. In order to solve these problems, during the construction and maintenance of the pipeline, it is often necessary to effectively deal with these gaps and other defective parts.

[0004] Among them, pouring specific glue is a common and effective method. By accurately pouring the appropriate glue into the joints or defective parts of the pipeline, gaps can be filled, structural strength can be enhanced, leakage can be prevented, and the overall performance and service life of the pipeline can be improved. Currently, there are two common methods: 1. Manual glue gun: Manual glue gun requires the constructor to have certain operating experience and skills. Due to manual operation, the glue output speed will be uneven, which will affect the construction quality and appearance, and the construction efficiency cannot be guaranteed; 2. Electric glue injection gun: Electric glue injection guns are relatively expensive, and the speed cannot be adjusted arbitrarily during use. At the same time, too fast speed during the gluing process will cause high pressure and severe force on the booster piston, which makes the glue bottle unable to withstand it, and may eventually cause glue leakage.

The present invention can be used in conjunction with most electric drills 8, and the electric drill 8 is used as a power source to drive the transmission assembly to drive the push rod 5, thereby performing glue injection. With the advantage that the electric drill 8 can perform multi-stage speed regulation, the advancement speed of the push rod 5 can be conveniently controlled, thereby controlling the glue injection speed. Compared with the traditional electric glue injection gun, the present invention has a simple overall structure and low cost, and only needs to be used as a "special drill bit" of the electric drill 8.

[0025] The transmission assembly includes a worm wheel 9, a worm 10, a gear 11 and a rotating rod 12. The rotating rod 12 is horizontally arranged in the transmission part 4 along the left-right direction. The worm wheel 9 and the gear 11 are both sleeved on the rotating rod 12.

The gear 11 rotates forward and can drive the push rod 5 to move forward through the tooth opening 13 on the push rod 5, thereby pushing the rubber hose for injection. The gear 11 rotates backward and can drive the push rod 5 to move backward, thereby resetting the push rod 5, which is convenient for replacing the rubber hose. A push block is provided at the front end of the push rod 5, which can push the rubber hose more smoothly. In order to facilitate the movement of the push rod 5, aligned sliding holes 6 are provided on the front and rear sides of the transmission part 4, the middle part of the push rod 5 is placed in the transmission part 4, the front end of the push rod 5 is provided with a push block in the injection groove 2, and the rear end of the push rod 5 is provided with a limited block on the rear side of the transmission part 4. A relatively simple mechanical structure is adopted to realize the transmission steering function of the electric drill 8, so that the electric drill 8 is used as the power source to complete the rubber extrusion action. The device is small in size, and the occupied space and carrying method can be flexibly arranged. According to this movement logic, it can be applied to various application scenarios that require glue injection. It only needs to replace different types of barrel shapes to complete the injection of various shapes and multiple types of rubber.
