Description

Technical Field

[0001] This utility model belongs to the field of pipeline equipment technology and relates to a pipeline centering support. Background Technology

[0002] During the construction of urban water conservancy pipelines, a complete drainage system needs to be built. During construction, it is necessary to construct according to the actual road conditions. In actual operation, the pipeline needs to be cut and then installed in the appropriate place. If manual cutting is used, the large size of the pipeline can easily cause vibration during the cutting process.

[0003] Therefore, in order to improve cutting accuracy, existing pipe clamping self-centering devices have been developed. For example, Chinese patent application [Authorization Announcement No.: CN210588204U] discloses a pipe clamping self-centering device for clamping the pipe to be processed. It includes a machine body, a clamping position for placing the pipe to be processed, clamping blocks that are movably disposed in the machine body, and two clamping blocks. The gap between the two clamping blocks forms the clamping position. A transmission mechanism is also included. Under the drive of the transmission mechanism, the two clamping blocks move synchronously closer to or further away from each other.

[0004] Although the above structure can clamp the pipe, it only clamps and positions the pipe in the left and right directions using clamping blocks. However, in actual operation, the pipe will vibrate due to cutting. The clamping and positioning in the left and right directions is not stable, and the pipe will still vibrate and slip in the vertical direction, resulting in poor pipe positioning and affecting the stability of pipe cutting. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a pipe centering support. The technical problem to be solved by this utility model is: how to solve the problem of poor pipe positioning effect in existing technologies.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A pipe centering bracket includes a base with an upward-facing mounting groove. Support rollers are rotatably connected to both sides of the base. The bracket is characterized by a clamping seat hinged to one side of the base, which can swing around the hinge point. The other side of the clamping seat is inserted into the other side of the base. The pipe centering bracket includes a positioning element that positions the other side of the clamping seat relative to the other side of the base. The clamping seat has a vertically sliding and positioning clamping rod, the lower end of which has a clamping block. After the clamping seat and base are positioned by the positioning element, the clamping block is located above the support rollers and can clamp the pipe to be processed onto the support rollers.

[0008] Working principle: First, the clamping seat is opened along the hinge point. After opening, the pipe to be processed is placed on the support roller. With the support of the support roller, the clamping seat swings along the hinge point, so that the other side of the clamping seat is inserted into the other side of the base. The other side of the clamping seat is connected to the other side of the base by the positioning component. The vertically sliding clamping rod to the clamping block on the clamping rod presses the pipe to be processed onto the support roller. Thus, the two support rollers limit the left and right directions of the pipe to be processed. Through the cooperation of the clamping block and the support roller, the vertical and front and back directions of the pipe to be processed are achieved. This allows the pipe to be processed to be stably positioned by the cooperation of the support roller and the clamping block, which facilitates subsequent processing.

[0009] In the aforementioned pipe centering support, there are two clamping blocks, which are distributed along the front-back direction and are located on the front and back sides of the support roller, respectively.

[0010] By setting two clamping blocks distributed along the front and back, one of the clamping blocks can form a three-point positioning with the two support rollers, which improves the positioning effect of the pipe to be processed. The front and back distribution of the two clamping blocks can enhance the positioning strength of the pipe to be processed in the front and back direction, and improve the positioning stability.

[0011] In the aforementioned pipe centering support, the clamping block is V-shaped, and the lower end surface of the clamping block has multiple downward-protruding anti-slip strips, the length direction of which is distributed along the front-back direction.

[0012] The shape of the clamping block allows for positioning of pipes with different diameters, and the anti-slip strip prevents the pipe from rotating circumferentially during cutting, thus improving positioning stability.

[0013] In the aforementioned pipe centering support, an elastic buffer block is provided at the other end of the clamping seat, and the elastic buffer block is embedded in the other side of the base.

[0014] The elastic buffer block reduces the impact on the base when the other side of the clamping seat is inserted into the base, resulting in a better noise reduction effect.

[0015] In the above-mentioned pipe centering support, the positioning element is a pin, the base is provided with a positioning hole for the pin to be inserted, and the elastic buffer block is provided with a limiting hole for the pin to be inserted. The pin can be inserted into the positioning hole and the limiting hole to realize the connection and positioning of the base and the clamping seat.

[0016] This structure allows the clamping seat to be directly positioned by the pin after being inserted into the base, improving the convenience and stability of positioning and facilitating disassembly.

[0017] Positioning components can also be bolts or other similar parts.

[0018] In the aforementioned pipe centering support, the clamping rod is a lead screw, which is threadedly connected to the clamping seat, and a rotating handle is connected to the upper end of the clamping rod.

[0019] This structure makes the vertical movement of the clamping rod more convenient, and the threaded connection between the screw and the clamping seat also provides a good positioning effect, improving the ease of use of the pipe centering support.

[0020] In the aforementioned pipe centering support, the clamping blocks are all made of rubber material.

[0021] This structure enhances the friction between the pipe and the surrounding structure, reduces noise from impacts with the pipe, and prevents scratches on the pipe's outer wall.

[0022] Compared with existing technologies, this pipe centering support has the following advantages: the left and right directions of the pipe to be processed are limited by the setting of two support rollers, and the vertical and front and back directions of the pipe to be processed are achieved by the cooperation of the clamping block and the support rollers. This allows the pipe to be processed to achieve stable positioning through the cooperation of the support rollers and the clamping block, which facilitates subsequent processing.

The clamping blocks 32 are V-shaped, and the lower end surface of the clamping blocks 32 has multiple downward protruding anti-slip strips 32a. The length direction of the anti-slip strips 32a is distributed along the front-back direction.

[0032] like Figure 2 and Figure 3 As shown, the other end of the clamping seat 3 is provided with an elastic buffer block 33, which is embedded in the other side of the base 1. The positioning element 4 is a pin. The base 1 is provided with a positioning hole 12 for the pin to be inserted, and the elastic buffer block 33 is provided with a limiting hole 33a for the pin to be inserted. The pin can be inserted into the positioning hole 12 and the limiting hole 33a to realize the connection and positioning of the base 1 and the clamping seat 3.
