Description

Technical Field

[0001] This utility model belongs to the field of pipe bending technology, specifically relating to a fire protection construction pipe bending device. Background Technology

[0002] Fire protection pipelines are an important component of fire protection systems. Their function is to transport water or other fire extinguishing media from fire water sources (such as fire pools, water tanks, municipal water supply networks, etc.) through a series of pipeline networks to various fire protection equipment and fire extinguishing facilities, such as fire hydrants, automatic sprinkler system nozzles, water curtain nozzles, fire monitors, etc.

[0003] In practical use, due to different installation environments, it is sometimes necessary to use pipe bending equipment to bend fire protection pipes to facilitate their installation and use. According to their working principle, pipe bending equipment mainly includes hydraulic pipe bending machines, CNC pipe bending machines, and spiral pipe bending machines. Usually, the pipe is fixed from both ends first, and then the pipe is bent from the middle.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN219483852U discloses "a fire protection construction pipeline bending device", which includes a bending table, two drive motors fixedly connected to the rear of the top of the bending table, and a bending column fixedly connected to the rear of the bottom of the bending table. Guide grooves are provided on the side of the top and the side of the bottom of the bending table, and a gear plate is fixedly connected to the output end of the drive motor.

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

With the above scheme, in use, the pipe to be bent is passed through the inner space between the bending wheel 3 and the support wheel 6. The support wheel 6 supports and limits the pipe. Then, the drive mechanism 4 is activated to drive the main wheel frame 2 to move downwards, causing the bending wheel 3 to move downwards. The bending wheel 3 presses down on the pipe, and in conjunction with the support wheel 6, it presses down on the pipe. The support wheel 3 provides support for pipe bending. Since both the bending wheel 3 and the support wheel 6 are detachable, it is convenient to replace them with different sizes for pipes of different diameters. When necessary, the adjustment mechanism 7 can be activated to drive the auxiliary wheel frame 5 to move, thus moving the support wheel 6 and adjusting the initial distance between the two support wheels 6. The detachable bending wheel 3 and support wheel 6 of this invention facilitate the replacement of different sizes for pipes of different diameters, and different bending radii can be achieved by replacing the bending wheel 3 with different sizes. The initial distance between the two support wheels 6 is adjustable, suitable for different bending requirements and pipes of different lengths, with a wide range of applications, including most common fire-fighting pipes.

[0056] Optionally, by Figure 1 and Figure 2As shown in this embodiment, the main wheel frame 2 includes: an inverted L-shaped bracket 21, a baffle 22, and a second wing nut 9.

At the same time, it is also convenient to replace bending wheels 3 of different sizes according to actual processing needs.

[0057] It is worth noting that, as shown in the attached figure, there is an arc-shaped groove on the circumferential surface of the bending wheel 3, which can be adapted to the circumferential surface of the pipe to ensure the stability of the pipe during processing and prevent the pipe from slipping. In addition, to reduce the sliding friction between the bending wheel 3 and the pipe, a rubber sleeve can be fixed on the circumferential surface of the bending wheel 3.

The threaded screw 44 is rotatably installed between the two first fixed plates 43, and the threaded screw 44 passes through the first moving plate 42 and is connected to the first moving plate 42 by threaded engagement. The driving motor 45 is fixed on the first fixed plate 43 and is used to drive the threaded screw 44 to rotate. With the above scheme, when in use, the driving motor 45 is started to drive the threaded screw 44 to rotate.

The two second guide rods 74 are symmetrically fixed to the outer wall of the second moving plate 71, and the second guide rods 74 penetrate the second fixed plate 72. With the above scheme, in use, the two second guide rods 74 are used to guide the second moving plate 71, which further improves the stability of the second moving plate 71, thereby improving the stability of the support wheel 6.

[0064] Preferably, by Figure 1 and Figure 5 As shown, this embodiment also includes two sets of symmetrically distributed auxiliary guiding mechanisms 8, and the auxiliary guiding mechanism 8 includes: a guide sleeve 81 and an I-shaped slider 82.

With the above scheme, when in use, the end of the pipe passes through the guide sleeve 81 to guide and stabilize the pipe. After the pipe is bent, the end of the pipe will rise, which will drive the guide sleeve 81 to rotate and drive the I-shaped slider 82 to slide upward in the second guide sliding hole 102.

[0065] Optionally, by Figure 1 and Figure 5 As shown in this embodiment, the auxiliary guiding mechanism 8 further includes: a second threaded rod 83 and a first wing nut 84.
