Description

Technical Field

[0001] This invention relates to the field of pipeline embedded parts construction technology, and in particular to a pipeline embedded parts fixing device. Background Technology

[0002] Embedded parts (precast embedded parts) are components pre-installed (embedded) within concealed works. They are components placed during structural pouring and used for overlapping during the construction of the superstructure to facilitate the installation and fixing of external engineering equipment foundations. Pipe embedded parts refer to channels left in concrete structures for pipes (commonly steel pipes, cast iron pipes, or PVC pipes) to pass through or to leave openings for equipment, such as for various pipelines (e.g., power, water supply, gas, etc.) to be run later. They are often used for pipe pre-reserved holes in concrete walls and beams.

[0003] Pipeline embedded parts need to be fixed according to the construction location during construction. Traditionally, pipeline embedded parts are fixed to the bottom formwork of the top slab by nailing four iron nails around the perimeter of the pipeline. After the formwork is removed, the iron nails are broken off manually. However, the iron nails are still partially embedded in the concrete structure, and the concrete slab is also easily damaged, which may cause water seepage problems later. Chinese patent with publication number CN218094619U discloses a portable water and electricity pipeline embedded fixing device. The bottom fixing part is fixed to the bottom of the inner cavity of the water and electricity pipeline body and permanently fixed to the formwork by steel nails on both sides. This solves the problems of iron nails being partially embedded in the concrete structure, easy concrete damage, and water seepage problems. However, the steel nails fixed to the formwork cause damage to the formwork and affect subsequent use. Moreover, the bottom fixing part cannot be removed from the water and electricity pipeline body, which also affects the use of the pipeline later.

[0004] Based on this, this application designs a technical solution that does not require the use of steel nails to stably fix the pipe pre-embedded parts and can be easily removed. Summary of the Invention

[0005] The present invention provides a pipe pre-embedded part fixing device, which can solve the problems mentioned above, such as the need to fix steel nails on the template, which causes damage to the template and affects subsequent use, and the bottom fixing part cannot be removed from the pipe.

Side telescopic rods are provided between the support bases, and side telescopic springs are sleeved on the outer sides of the side telescopic rods. The two ends of the side telescopic springs are respectively connected to the opposite sides of the two side support bases. The side support bases have a hollow cavity structure. Vertical slides are provided on the front and rear inner walls of the cavity structure at the ends away from the side telescopic springs, and horizontal slides are provided on the front and rear inner walls of the cavity structure at the ends close to the side telescopic springs. The trapezoidal block cooperates with the horizontal slides, and the moving block cooperates with the vertical slides, with the end of the moving block away from the trapezoidal block extending out of the side of the side support base. The upper end of the trapezoidal block is connected to a hinge seat.

[0009] Preferably, the bottom support assembly includes a bottom telescopic rod one, a bottom telescopic rod two, and a bottom telescopic spring; the bottom telescopic rod one is slidably connected to the side support base via a slider, and the bottom telescopic rod one and the bottom telescopic rod two are slidably connected via the bottom telescopic spring.

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0021] See Figure 1 A pipe pre-embedded component fixing device includes a base 1, a motor 2 fixedly installed on the base 1, a support rod 3 installed on the motor 2 via a circular plate, a telescopic rod 4 horizontally installed on the upper end of the support rod 3, a telescopic cylinder for controlling the extension and retraction of the telescopic rod 4 installed on the telescopic rod 4, a lifting cylinder 5 installed on the lower right side of the telescopic section of the telescopic rod 4, and an inner support mechanism 6 for supporting the pipe pre-embedded component symmetrically connected to the bottom end of the lifting cylinder 5 via an mounting plate.

[0022] See Figure 1 In actual operation, the base 1 is fixed to the wall where no concrete needs to be poured by bolts. The motor 2 and telescopic cylinder are started to control the inner support mechanism 6 to move directly above the pipe pre-embedded part. The lifting cylinder 5 is started to control the inner support mechanism 6 to descend and provide internal support for the pipe pre-embedded part.

[0023] See Figure 1 The inner support mechanism 6 includes a side support component 61 and a bottom support component 62. During operation, the lifting cylinder 5 drives the inner support mechanism 6 to descend. The bottom support component 62 first contacts the bottom template of the top plate. As the lifting cylinder 5 extends, the side support component 61 gradually contacts the inner wall of the pipe embedded part and provides internal support.

[0024] See Figure 1 and Figure 2 The side support assembly 61 includes a side support base 611, a side telescopic rod 612, a side telescopic spring 613, a hinge rod 614, a hinge seat 615, a return spring 616, a trapezoidal block 617, and a moving block 618. The lower end face of the telescopic section of the lifting cylinder 5 is symmetrically hinged to the hinge rod 614 via a square plate. The end of the hinge rod 614 away from the lifting cylinder 5 is rotatably connected to the hinge seat 615, which is slidably mounted on the side support base 611. A slide rail is provided in the middle of the upper end face of the side support base 611, and the slide rail is slidably engaged with the hinge seat 615. An ear plate is provided on the outer side of the upper end face of the side support base 611, and the ear plate is connected to the hinge seat 615 via a return spring 616. There are two side support bases 611. The two side support bases 611 are symmetrically arranged, with a side telescopic rod 612 between them. A side telescopic spring 613 is sleeved on the outside of the side telescopic rod 612, and the two ends of the side telescopic spring 613 are respectively connected to the opposite sides of the two side support bases 611. The side support base 611 has a hollow cavity structure. Vertical slides are opened at the ends of the front and rear inner walls of the cavity structure away from the side telescopic spring 613, and horizontal slides are opened at the ends of the front and rear inner walls of the cavity structure near the side telescopic spring 613. The trapezoidal block 617 cooperates with the horizontal slide, and the moving block 618 cooperates with the vertical slide, with the end of the moving block 618 away from the trapezoidal block 617 extending out of the side of the side support base 611. The upper end of the trapezoidal block 617 is connected to the hinge seat 615.

[0025] Please continue reading. Figure 1 and Figure 3 The bottom support assembly 62 includes a bottom telescopic rod 621, a bottom telescopic rod 622, and a bottom telescopic spring 623; the bottom telescopic rod 621 is slidably connected to the side support base 611 via a slider, and the bottom telescopic rod 621 and the bottom telescopic rod 622 are slidably connected via the bottom telescopic spring 623.

[0026] The elasticity of the bottom telescopic spring 623 is less than that of the side telescopic spring 613, and the elasticity of the side telescopic spring 613 is less than that of the return spring 616. In operation, the lifting cylinder 5 drives the inner support mechanism 6 to descend, and the bottom support assembly 62 contacts the bottom template of the top plate. Because the elasticity of the bottom telescopic spring 623 is less than that of the side telescopic spring 613, the bottom telescopic spring 623 is compressed. When the bottom telescopic spring 623 is compressed to its maximum extent, as the lifting cylinder 5 continues to extend, the elasticity of the side telescopic spring 613 is less than that of the return spring 616. The side extension spring 613 is stretched first, and the two side support bases 611 move in opposite directions against the elastic force of the side extension spring 613 until the side of the moving block 618 contacts the inner wall of the pipe. At this time, the lifting cylinder 5 continues to extend, the return spring 616 is compressed, and the hinge seat 615 drives the trapezoidal block 617 to slide outward. The trapezoidal block 617 cooperates with the moving block 618 to drive the moving block 618 to move vertically downward, thereby applying downward pressure to the inner wall of the pipe embedded part, ensuring the stability of the pipe embedded part and improving the concrete pouring effect.

[0027] See Figure 1 An inclined support 7 is hinged between the support rod 3 and the telescopic rod 4 to support the telescopic rod 4. The inclined support 7 includes an inclined support rod one and an inclined support rod two, which are connected by a spring. When the telescopic rod 4 extends or retracts, the inclined support 7 adjusts accordingly.

[0028] See Figure 1 The base 1 is evenly provided with motor support rods in the circumferential direction, and the bottom surface of the circular plate is provided with a circular groove. The upper end of the motor support rod is slidably engaged with the circular groove to support the circular plate.

[0029] See Figure 2 The movable block 618 extends outward from the side of the side support base 611 and is equipped with a rubber block to prevent the movable block 618 from contacting the inner wall of the pipe and causing damage.

[0030] The working process of this invention is as follows: the base 1 is fixed to the wall that does not require concrete pouring by bolts, the motor 2 and the telescopic cylinder are started to control the inner support mechanism 6 to move directly above the pipe pre-embedded part, the lifting cylinder 5 is started to control the inner support mechanism 6 to descend, the bottom telescopic rod 622 and the moving block 618 contact the bottom template of the top plate and the inner wall of the pipe in turn, thereby fixing the pipe pre-embedded part. When the inner support mechanism 6 is removed from the pipe pre-embedded part, the lifting cylinder 5 is used to lift the inner support mechanism 6, and the side support assembly 61 and the bottom support assembly 62 are reset.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
