Description

Technical Field

[0001] The utility model relates to the technical field related to pipe wall thickness measurement, in particular to a novel large-diameter pipe wall thickness laser measuring device. Background Art

[0002] Large-diameter, thick-walled pipes are often used in industrial pipelines and oil and gas transportation. Large-diameter, thick-walled pipes are widely used. They can not only withstand high pressure and high temperature environments, but also ensure the stability and reliability of fluid transportation. Large-diameter, thick-walled pipes have high pressure resistance and wear resistance. Their wall thickness is large and can withstand greater pressure and friction, thereby ensuring the service life and stability of the pipe.

[0003] Large-diameter and thick-walled pipes need to have their wall thickness measured before leaving the factory. The commonly used measuring device for pipe wall thickness is a micrometer. Micrometer measurement is more suitable for small-diameter pipes, but for large-diameter pipe wall thickness, this measurement method has limited measurement data and is prone to errors during measurement, making it impossible to verify the actual wall thickness of the pipe.

[0004] The utility model aims to provide a novel large-diameter pipe wall thickness laser measuring device to solve the problems raised in the above background technology.

[0024] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0026] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0027] See also Figure 1 to Figure 3 In the embodiment of the utility model, a novel large-diameter pipe wall thickness laser measuring device includes a laser measuring instrument 1, a fixing device 2, a connecting rod 4, a data recording and analyzing instrument 5 and a driving part.

[0028] The details are as follows;

[0029] See also Figure 1 , Figure 2 , the fixing device 2 can be detachably connected to the inner wall of the pipe;

[0030] The driving member is installed on one side of the fixing device 2, and the connecting rod 4 is installed on the output end of the driving member;

[0031] The laser measuring instrument 1 is installed at one end of the connecting rod 4 away from the driving member and is formed with a U-shaped portion, and the side wall of the pipe is inserted into the U-shaped portion;

[0032] The data recorder and analyzer 5 establishes communication with the laser measuring instrument 1 .

[0033] In detail, in this embodiment, the new large-diameter pipe wall thickness laser measuring device described in the utility model is adopted. When in use, the fixing device 2 is installed in the pipe to be measured, and the distance of the connecting rod 4 is adjusted so that the pipe wall thickness is located in the U-shaped portion of the laser measuring instrument 1. When the control driving member is working, the laser measuring instrument 1 starts measuring and drives the laser measuring instrument 1 to rotate one circle relative to the pipe wall thickness. During the process, the measured wall thickness data is transmitted to the data recording and analyzing instrument 5 in real time. At this time, the data recording and analyzing instrument 5 automatically performs statistical analysis on the collected pipe wall thickness data to complete the measurement of the pipe wall thickness and reduce the measurement error.

[0034] Preferably, the fixing device 2 includes a connecting seat and a plurality of telescopic parts formed on the side end of the connecting seat, wherein the length of the telescopic parts changes along the radial direction of the pipe, so that the fixing device 2 can be detachably connected to pipes of different diameters to meet the support requirements of the fixing device 2 in the pipe.

[0035] Preferably, the multiple telescopic parts are distributed in a circle, and the distance between two adjacent telescopic parts is the same. In order to ensure the stable support of the fixing device 2 as a whole in the pipe, the two adjacent telescopic parts are in a vertical or parallel state, so that the supporting forces of the multiple telescopic parts on the inside of the pipe are relative, thereby improving stability.

[0036] The telescopic member comprises a threaded sleeve rotatably mounted on the connecting seat and a threaded rod threadedly connected to the threaded sleeve, and an abutment position is formed at one end of the threaded rod away from the threaded sleeve.

[0037] It should be noted that before measurement, the above-mentioned fixing device 2 is placed on the inner side of the pipe, and multiple threaded rods are rotated at the same time, so that the threaded rods make linear motion along the axial direction of the threaded sleeve until the abutment position on the threaded rod abuts against the inner wall of the pipe, wherein the abutment position is arranged in an arc-shaped structure, so that the contact area between the abutment position and the inner wall of the pipe is increased to increase the supporting force on the threaded rod. At this time, the threaded rod is rotated, and the threaded rod drives the threaded sleeve to make linear motion along the axial direction of the threaded rod when the threaded rod rotates, and the supporting force between the abutment position and the inner wall of the pipe is further increased to achieve a stable connection of the fixing device 2 in the pipe.

[0038] Preferably, a rubber pad is fixed to one end of the threaded rod away from the threaded sleeve, and the rubber pad forms the abutment position. The rubber pad has a certain friction force, which can increase the friction force between the threaded rod and the inside of the pipe and provide stable support.

[0039] Preferably, a receiving frame is formed on the fixing device 2, and the receiving frame is arranged parallel to the axial direction of the pipe, and the driving member is installed at one end of the receiving frame.

[0040] Preferably, the driving member includes a motor 3 , and the motor 3 is fixedly mounted on the supporting frame, and the output shaft of the motor 3 is vertically fixed to the connecting rod 4 .

[0041] To elaborate, the motor 3 adopts an adjustable frequency motor. By setting the speed parameters of the motor 3, the speed at which the laser measuring instrument 1 measures the wall thickness of the pipe can be adjusted. The motor 3 is started to work, and the motor 3 drives the output shaft to rotate, so that the connecting rod 4 rotates synchronously, so that the motor 3 automatically stops after one circle of rotation. The laser measuring instrument 1 also completes the thickness measurement of the pipe wall thickness for one circle. At this time, the measured data is sent to the data recording and analyzing instrument 5 in real time through the Bluetooth device on the laser measuring instrument 1. The data recording and analyzing instrument 5 records, analyzes and processes the transmitted data, and finally obtains data information such as the maximum wall thickness value, the minimum wall thickness value, and the average wall thickness value.

[0042] The connecting rod 4 includes a connecting shaft and a connecting sleeve slidably connected to the connecting shaft, the laser measuring instrument 1 is fixed to one end of the connecting shaft away from the connecting sleeve, and the connecting sleeve is fixed to the output shaft of the motor 3;

[0043] It also includes a locking piece, which connects the connecting shaft and the connecting sleeve.

[0044] See also Figure 3 The locking member 6 includes a locking protrusion 6, a sliding groove is formed on the connecting shaft, and the locking protrusion 6 is slidably arranged in the sliding groove. An arc-shaped abutting surface is formed on the end of the locking protrusion 6 away from the connecting shaft, and a spring is also arranged in the sliding groove. A plurality of locking grooves 7 are formed on the connecting sleeve that engage with the locking protrusion 6. When the locking protrusion 6 is inserted into the locking groove 7, the connecting shaft is locked and cannot move relative to the connecting sleeve. By pressing the locking protrusion 6, the spring is squeezed and the locking protrusion 6 gives way. At this time, the connecting shaft is rotated, the arc-shaped abutting surface and the connecting sleeve are squeezed against each other, and the locking protrusion 6 is completely inserted into the connecting shaft, so that the connecting shaft can slide freely relative to the connecting sleeve without affecting the locking of the connecting sleeve on the connecting shaft.
