Description

Technical Field

[0001] The utility model relates to the technical field of pipe making machines, and more specifically, to a movable linear speed detector. Background Art

[0002] A pipe making machine, also known as a welded pipe machine or a pipe making unit, is a mechanical device for producing various pipes. According to different production materials, pipe making machines are mainly divided into two categories: high-frequency pipe making machines and stainless steel pipe making machines.

[0003] The pipeline speed (or linear speed) of a pipe making machine is affected by various factors, including the model of the pipe making machine, the specifications of the pipe material (such as wall thickness and diameter), the production process, and the technical parameters of the equipment. In order to accurately obtain the pipeline speed of the pipe making machine, the prior art usually sets rollers below the pipeline. When the pipeline exits, the pipeline will drive the rollers to rotate. At this time, monitoring the rotation speed of the rollers can obtain the pipeline speed. However, the current roller speed measuring device cannot effectively contact the pipeline stably, easily causing intermittent empty friction of the pipeline on the rollers, affecting the detection accuracy. At the same time, the angle and height of the existing speed measuring device cannot be adjusted conveniently, which will also affect the detection efficiency and accuracy.

In actual installation, a plurality of bolts 13 are arranged along the height direction of the lifting frame plate 11. When it is necessary to adjust the height of the sliding plate 4, only need to loosen the bolt 13 at the position of the sliding plate 4, and then adjust the position of the sliding plate 4 in the chute opening 12. After the adjustment is completed, tighten the bolt 13 again. One end of the suspension frame plate 3 is connected to the sliding plate 4 through a locking mechanism 8. The main driving wheel 5 is rotatably installed at the other end of the suspension frame plate 3. A protruding plate with an integral structure is provided at the position below the main driving wheel 5 on the suspension frame plate 3. An elastic mechanism 7 is fixedly installed on the surface of the protruding plate. The pressure roller 6 is installed on the elastic mechanism 7. The pressure roller 6 is in rolling contact with the main driving wheel 5 through the elastic action of the elastic mechanism 7. An encoder 9 and an L-shaped support plate 31 are fixedly installed on one side of the suspension frame plate 3 away from the main driving wheel 5. The encoder 9 is fixedly installed on the outside of the L-shaped support plate 31. The output shaft of the encoder 9 is fixedly connected to the main driving wheel 5 through a coupling 91. A display screen 21 for displaying the data of the encoder 91 is fixedly installed outside the control cabinet 2.

[0021] To ensure that the pressure roller 5 can stably roll and contact pipelines of different sizes, in this embodiment, the elastic mechanism 7 includes a receiving box 71 and a spring 73. The receiving box 71 is fixedly installed on one side of the suspension frame plate 3. The receiving box 71 is located below the main driving wheel 5. A chute opening 72 is formed on the outer side of the receiving box 71. One end of the pressure roller 6 is fixedly provided with a convex shaft 61.

A bearing 74 is sleeved on the surface of the convex shaft 61. The spring 73 is fixedly installed at the inner bottom of the receiving box 71. The upper end of the spring 73 is fixedly connected to the bearing 74. The bearing 74 plays a role in limiting and facilitating the smooth rotation of the convex shaft 61.

The main driving wheel 5 and the pressure roller 6 can stably clamp the pipeline. When the pipeline moves, it can drive the main driving wheel 5 to rotate. The encoder 91 can real-time monitor the rotation speed of the main driving wheel 5. Through the calculation and processing of the microcontroller, the speed data can be displayed on the display screen 21.
