Description

Technical Field

[0001] This utility model relates to the field of underfloor heating construction technology, specifically to a rotary pipe feeding device for underfloor heating coil construction. Background Technology

[0002] When laying underfloor heating pipes, since most underfloor heating pipes are coiled, it is usually time-consuming and labor-intensive for one worker to lay the pipes and another worker to lay them. In existing technologies, a simple pipe laying device is also used to assist in pipe delivery. The underfloor heating coils are placed on the turntable of the pipe laying device. When the worker pulls out the underfloor heating pipes, it drives the turntable of the pipe laying device to rotate, thus delivering the pipes.

[0003] However, most existing pipe-laying devices are simple rotating structures, which are prone to loosening and rewinding during actual construction. Specifically, after the pipe stops being pulled out, the turntable may rotate due to uneven friction, causing the pipe to rewind. At the same time, since the pipe tension is provided by the worker during the pipe delivery process, the pipe tension is unstable. When the coil is subjected to too little or too much force, the tension between the coil layers is uneven, which may also cause local loosening or rewinding. Loosening and rewinding can cause the coil to misalign or twist, which increases the amount of manual work required and may also damage the pipe surface, reducing construction efficiency and quality. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a rotary pipe feeding device for underfloor heating coil construction, thereby resolving the issues of the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A rotary pipe feeding device for underfloor heating coil construction is used to rotary feed out coiled underfloor heating pipes.

The pressure plates 42 are arc-shaped plates, and the outer side of the pressure plates 42 can abut against the inner side of the underfloor heating coil 6 to support the underfloor heating coil 6 internally. The connecting plate 43 is arranged between the corresponding pressure plate 42 and the locking post 41. The connecting plate 43 and the corresponding pressure plate 42 are connected by several support springs 45. The support springs 45 are arranged at intervals from top to bottom. The pressure plate 42 provides micro-tension to the underfloor heating coil 6 through the support springs 45.

[0032] The connecting plate 43 has push rods 44 at both its upper and lower ends on the side near the locking post 41. The push rods 44 are installed on the locking post 41 through threaded grooves 411. The distance between the upper and lower push rods 44 is the same as the distance between two adjacent threaded turns. Guide plates 23 are respectively provided on both sides of the outside of the locking post above the rotating seat 2. The push rods 44 pass through the guide plates 23 and are inserted into the threaded grooves 411 of the locking post 41. The guide plates 23 correspond one-to-one with the connecting plate 43. Two guide holes are opened on the guide plates 23 from top to bottom. The push rods 44 pass through the corresponding guide holes. The end of the push rod 44 near the locking post 41 is provided with a protrusion that matches the shape of the limiting groove. Both the limiting groove and the protrusion can be The shape can be spherical, or square, etc., to restrict the push rod 44 from disengaging from the threaded groove 411; the lower outer surface of the locking post 41 has an installation groove 413, which connects two adjacent threaded grooves 411. The width of the installation groove 413 is slightly larger than the width of the threaded groove 411, so that the protrusion of the push rod 44 can be inserted into the limiting groove 411 through the installation groove 413. Preferably, the installation groove 413 connects the two adjacent threaded grooves 411 at the bottom of the locking post 41; by holding the locking handle 412 and rotating it, the locking post 41 moves up and down spirally around the central post 22, the length of the push rod 44 extending into the threaded groove 411 can be varied, and the connecting plate 43 can move radially.

[0033] Furthermore, the guide rod assembly 5 includes a follower rod 51, a support rod 52, a first guide rod 53, and a second guide rod 54. The first guide rod 53 and the second guide rod 54 are fixedly disposed at the edge of the rotating seat 2. The support rod 52 and the follower rod 51 are located between the first guide rod 53 and the second guide rod 54. The first guide rod 53 is positioned close to the central column 22, and the second guide rod 54 is positioned away from the central column 22. The support rod 52 is fixedly disposed on the rotating seat 2. The follower rod 51 is connected to the support rod 52 via a follower spring 55. The moving spring 55 is arranged from top to bottom between the follower rod 51 and the support rod 52. The rotating seat 2 has a limiting groove 24 at the corresponding position of the lower end of the follower rod 51. The lower end of the follower rod 51 extends into the limiting groove 24 and can slide along the limiting groove 24. The pipe head of the underfloor heating coil 6 passes through the guide rod 1 53, the follower rod 51 and the guide rod 2 54 in succession before being sent out. When the tension of the pipe changes due to the worker pulling it, the following spring 55 can drive the follower rod 51 to move slightly to adjust it, thereby maintaining the stability of the pipe tension.

[0034] In this embodiment, when in use, operating the locking handle 412 moves the locking post 41 downwards, and the connecting plate 43 moves radially towards the locking post 41, placing the underfloor heating coil 6 on the rotating seat 2. Reversing the operation of the locking handle 412 moves the connecting plate 43 until the pressure plate 42 abuts against the inner side of the rolled underfloor heating coil 6, thereby providing slight tension to the inside of the underfloor heating coil 6 and preventing it from loosening during rotation. The pressure block assembly 3 is then fitted onto the central post 22, and the pressure block handle 311 is operated to press the pressure block... Component 3 is installed on the central column 22. The pressure component 3 can prevent the underfloor heating coil 6 from jumping up and loosening in the vertical direction when the pipe is delivered. Move the lever 14 until the pawl 12 engages with the ratchet 211 to make the rotating seat 2 rotate in one direction, so as to prevent the rotating seat 2 from rotating back when the pipe is delivered. After the pipe end of the underfloor heating coil 6 passes through the guide rod 1 53, the follower rod 51, and the guide rod 2 54 in sequence, it is delivered to the worker's hand. The follower rod 51 can maintain the stability of the pipe tension when the worker pulls the pipe, so as to avoid the phenomenon of local loosening or rewinding.

[0035] After the underfloor heating installation is completed, move the lever 14 to separate the pawl 12 from the ratchet 211, allowing the rotating seat 2 to rotate freely, making it easier for workers to collect and organize the remaining pipes; reverse the operation of the pressure handle 311, remove the pressure assembly 3, and take out the remaining underfloor heating coil 6.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
