Description

Technical Field

[0001] The utility model relates to the field of pipeline installation, in particular to a rounding device which is convenient for pipeline installation. Background Art

[0002] Pipeline installation refers to the process of arranging, installing and connecting piping systems in buildings, factories or other facilities in accordance with design requirements and specifications. These piping systems may be used to transport fluids or gases including water, oil, gas, and chemical products, and may also be used in HVAC systems.

[0003] In the prior art, since the pipeline may be corroded by the internal solution and impacted by the outside world at any time during use, there is a certain risk of deformation of the pipeline after long-term use.

[0004] However, in the actual pipeline connection process, if the pipeline to be connected has a certain degree of deformation, the edge of the subsequent pipeline will always be squeezed by the pipeline to be connected during the connection and installation process, thereby increasing the friction between the two, and making the pipeline connection process more laborious. As the deformation degree of the pipeline to be connected increases, the newly installed pipeline will gradually be unable to connect with it. Therefore, a rounding device that is convenient for pipeline installation is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a rounding device that is convenient for pipeline installation, aiming to improve the problem in the prior art that when pipelines are installed and connected after aging and deformation, the deformed pipelines hinder the installation and connection of new pipelines.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rounding device for facilitating the installation of a pipeline, comprising an outer ring, the inner side of the outer ring is fixedly connected with a fixing rib, the inner side of the fixing rib is provided with a bidirectional rounding device, and the lower end of the outer ring is provided with a movable damping device;

[0010] As a further description of the above technical solution:

[0011] The fixing ribs are provided in two groups, and the two groups of fixing ribs are symmetrically distributed about the center line of the outer ring. A threaded through hole is provided at the center of the inner surface of the rotating handle.

[0012] As a further description of the above technical solution:

[0013] An inclined rectangular groove is provided on the outer arc surface of the rotating handle. Two groups of threaded rods are provided, and the two groups of threaded rods are symmetrically distributed with the center line of the outer ring as the symmetry axis, and the threads of the two groups of threaded rods are opposite.

[0014] As a further description of the above technical solution:

[0015] A through hole is provided at the upper end of the inner surface of the fixing block, and one end of the threaded rod away from the rotating handle is fixedly connected to the fixing rib.

[0016] As a further description of the above technical solution:

[0017] The fixing block is elastically connected to the rotating shaft via a spiral spring, and an inclined arc surface is arranged at one end of the pressure rod away from the rotating handle.

[0022] The utility model has the following beneficial effects:

[0023] 1. The threaded rod, pressure rod, fixed block, rotating handle and rotating shaft provided in the utility model can drive the threaded rods on both sides to move toward or away from each other by rotating the handle when the pipes need to be connected, so that the outer ring gradually expands and rounds the pipes outside it. At this time, the connection of the two sets of pipes can be completed conveniently and labor-savingly by inserting the pipe to be connected, and the end arc surface scratching caused by forced insertion of the pipe can be avoided.

[0024] 2. The damping chamber, piston plate, buffer spring and piston rod provided in the utility model can enable the outer ring to always push the piston rod and the piston plate to move inside the damping chamber during the opening or contraction process, and the damping fluid provided inside the damping chamber forms the motion damping, thereby reducing the damage that may be caused to the operator when the outer ring contracts instantaneously and in large quantities, thereby improving the safety and stability of the device during use.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a rounding device for facilitating the installation of a pipeline, comprising an outer ring 1, a fixing rib 4 is fixedly connected to the inner side of the outer ring 1, a bidirectional rounding device 2 is arranged on the inner side of the fixing rib 4, and a movable damping device 3 is arranged at the lower end of the outer ring 1;

[0033] The bidirectional circle supporting device 2 includes a rotating handle 204, a threaded rod 201 is threadedly connected to the inner arc surface of the rotating handle 204, a fixed block 203 is fixedly connected to the outer arc surface of the rotating handle 204, a rotating shaft 205 is rotatably connected to the upper end of the inner surface of the fixed block 203, and a pressure rod 202 is fixedly connected to the outer arc surface of the rotating shaft 205.

[0034] Two groups of fixing ribs 4 are provided, and the two groups of fixing ribs 4 are symmetrically distributed with respect to the center line of the outer ring 1, so that the fixing ribs 4 can provide auxiliary support for the arc surface of the outer ring 1, thereby improving the stability of the device. A threaded through hole is provided at the center of the inner surface of the rotating handle 204, so that the threaded rods 201 on both sides can approach or move away from each other during the rotation process. An inclined rectangular groove is provided at the outer arc surface of the rotating handle 204, so that the end of the pressing rod 202 can be located here when it is pressed down, thereby reducing the discomfort caused by the contact between its edges and the operator's hand. Two groups of threaded rods 201 are provided, and the two groups of threaded rods 201 are symmetrically distributed with respect to the center line of the outer ring 1 as the symmetry axis. The threads of the two groups of threaded rods 201 are opposite, so that the two groups of threaded rods 201 can rotate when the rotating handle 204. During the process, they move towards or away from each other, and a through hole is provided on the upper end of the inner surface of the fixed block 203, so that the rotating shaft 205 can be accommodated to rotate inside it. The end of the threaded rod 201 away from the rotating handle 204 is fixedly connected to the fixed rib 4, and the fixed block 203 and the rotating shaft 205 are elastically connected by a spiral spring. The elastic force of the spiral spring will always drive the arc surface of the far end of the pressure rod 202 to contact the threaded rod 201, so that the pressure rod 202 can automatically limit the threaded rod 201 after people release the rotating handle 204. The pressure rod 202 is provided with an inclined arc surface at the end away from the rotating handle 204, and the inclined arc surface is set to rubber material. Therefore, when the arc surface is squeezed and contacted with the threaded rod 201 by the force of the spiral spring, the self-locking force of the threaded rod 201 can assist the position of the threaded rods 201 on both sides.

[0035] Reference Figure 1 and Figure 4 The movable damping device 3 includes a damping chamber 301, a piston on the inner surface of the damping chamber 301 is connected to a piston plate 302, a piston rod 304 is fixedly connected to the outer side of the piston plate 302, and buffer springs 303 are fixedly connected to the left and right ends of the damping chamber 301.

[0036] The interior of the damping chamber 301 is filled with liquid, which is damping liquid, so that the piston plate 302 can always be in contact with the damping liquid during movement. Through holes are provided at both ends of the damping chamber 301, so that the piston rod 304 can slide at both ends. Multiple groups of through holes are provided on the inner surface of the piston plate 302, so when it comes into contact with the damping liquid, the damping liquid will not completely block the movement of the piston plate 302, but will only hinder its movement. The piston rod 304 is piston-connected to the damping chamber 301, and the left and right ends of the damping chamber 301 are elastically connected to the outer ring 1 through the buffer spring 303. Therefore, when the outer ring 1 opens or contracts rapidly, the buffer spring 303 can buffer its movement.

[0037] Working principle: When using this device, it is necessary to first place it in the pipe waiting to be connected, and hold the rotating handle 204 and the inner end of the pressure rod 202. At this time, the pressure rod 202 will rotate around the rotating shaft 205 due to the force on one side, and drive its distal arc slope to rise, thereby releasing the angle limit of the threaded rod 201. At this time, the rotating handle 204 can be driven to rotate. When the rotating handle 204 rotates, it will gradually drive the threaded rods 201 on both sides away from each other, thereby rounding the pipe waiting to be connected.

[0038] At the same time, in the process of rounding the pipe, the pipe will continue to give the outer ring 1 a reaction force to contract inward, and this reaction force will also act on the threaded rods 201 on both sides, so that it tends to move toward the rotating handle 204. At this time, if the operator loses strength, the outer ring 1 will shrink and drive the two groups of piston rods 304 at its lower end to move into the damping bin 301. At this time, the buffer spring 303 will be impacted first to buffer the contraction force of the outer ring 1. At the same time, the piston rod 304 will also drive the piston plate 302 to squeeze the damping fluid stored in the damping bin 301 during the movement, and form the movement damping of the ends of the outer ring 1 on both sides through the damping fluid stored in the damping bin 301, thereby avoiding the outer ring 1 from shrinking a lot in an instant and causing harm to the user.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
