They are commonly used in thermal power engineering, petrochemical and other fields.

[0003] To ensure the safe operation of pipelines, measuring devices are usually installed on the pipelines during installation to monitor them. However, existing pipeline measuring devices can usually only measure pipelines of a specified specification. When measuring pipelines of different specifications, deviations are likely to occur, limiting their applicability.

[0036] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0037] Please see Figure 1-4 This utility model discloses a pipe measuring device, including a support platform 1 and a support frame 11 on the top for supporting the pipe;

[0038] The clamping component 2 includes two clamping rings 21 that are slidably disposed on the support platform 1. Each clamping ring 21 is arc-shaped and symmetrically distributed on both sides of the support frame 11 for clamping the pipe.

[0039] The adjusting component 3 includes a first adjusting assembly 31, which is disposed in the support platform 1 and connected to each clamping ring 21, for supporting each clamping ring 21 and driving them to move closer or further apart from each other;

[0040] The second adjustment component 32 is disposed in the support platform 1 and connected to the first adjustment component 31, and is used to drive each clamping ring 21 to move vertically up and down.

[0041] Measuring component 4 is mounted on the support platform 1 and connected to each clamping ring 21, and is used to measure the pipe diameter and pipe wall temperature.

[0042] In practice, when installing the pipeline, the workers first use the first adjusting component 31 to move each clamping ring 21 away from the support frame 11 to a suitable position. Then, the pipeline is placed on the support frame 11, and the second adjusting component 32 moves each clamping ring 21 vertically up and down until the clamping surface of each clamping ring 21 corresponds to the predetermined position of the pipeline wall. Then, the first adjusting component 31 moves each clamping ring 21 closer to each other until the clamping surface of each clamping ring 21 is in contact with the pipeline wall. At the same time, the measuring component 4 moves with the clamping ring 21 and contacts the pipeline wall to measure the diameter of the pipeline. After the pipeline is put into use, the measuring component 4 can monitor the temperature of the pipeline wall.

[0043] In this invention, by adjusting the operation of component 3, after the pipe is placed on the support frame 11, the second adjusting component 32 drives each clamping ring 21 to move to a predetermined position according to the actual pipe diameter, reducing measurement deviation. Then, the first adjusting component 31 drives the two clamping rings 21 to move closer to each other until they clamp the pipe, thereby further fixing the pipe. At the same time, the detection component moves together with the clamping rings 21 and contacts the outer wall of the pipe to monitor the pipe and improve applicability.

[0044] In one embodiment, the top surface of the support frame 11 is provided with two symmetrically distributed sliding grooves 12 located on both sides of the support frame 11;

[0045] The first adjustment component 31 includes a bidirectional lead screw 311 that is rotatably inserted into the support frame 11 and passes through each slide groove 12, and its surface is provided with two threaded sections 3111 with opposite directions of rotation.

[0046] Each groove 12 is also provided with a sliding block 312 that is threadedly connected to the corresponding threaded section 3111. When the bidirectional screw 311 rotates, it is used to drive the two sliding blocks 312 to move closer or further apart.

[0047] Each sliding block 312 is also vertically provided with a support rod 313 that is connected to the bottom of the corresponding clamping ring 21.

[0048] With this design, when it is necessary to clamp the pipe, the operator rotates the bidirectional screw 311 to drive the two sliding blocks 312 to move closer to each other, thereby causing each support rod 313 to drive the corresponding clamping ring 21 to move towards the center of the support frame 11 until each clamping ring 21 contacts the pipe wall and clamps it.

[0049] In one embodiment, the support rod 313 is a telescopic rod; the support platform 1 has a chamber 13 and an adjustment groove 14 that connects each slide groove 12 to the chamber 13;

[0050] The second adjustment assembly 32 includes a bidirectional adjustment group 321 disposed in the support platform 1. The bidirectional adjustment group 321 is composed of two adjustment rods 3211 that are slidably sleeved on each other and located in the chamber 13. Each adjustment rod 3211 is "L" shaped, and the vertical end of each adjustment rod 3211 passes through the corresponding adjustment groove 14 and passes through the fixed end of the corresponding sliding block 312 and the support rod 313 in sequence, and is connected to its telescopic end. Each adjustment rod 3211 is used to drive the corresponding support rod 313 to extend or retract.

[0051] Adjustment component 322 is disposed in chamber 13 and connected to each adjustment rod 3211, and is used to drive each adjustment rod 3211 to move vertically up and down.

[0052] With this design, when the two sliding blocks 312 move closer or further apart, each sliding block 312 drives the corresponding adjusting rod 3211 to move together in the corresponding adjusting groove 14. At this time, the sleeve ends of the two adjusting rods 3211 retract or extend towards each other, so as not to affect the movement of each sliding block 312. When it is necessary to adjust the height of the clamping ring 21, the adjusting component 322 drives each adjusting rod 3211 to move vertically up and down, so that each adjusting rod 3211 drives the telescopic end of the corresponding support rod 313 to extend and retract, thereby driving the clamping ring 21 to rise and fall.

[0053] In one embodiment, the adjusting member 322 includes a threaded rod 3221 that is vertically rotatably disposed in the chamber 13. An adjusting block 3222 is threadedly connected to the threaded rod 3221. The sleeve ends of the two adjusting rods 3211 are slidably disposed in the adjusting block 3222. When the threaded rod 3221 rotates, it is used to drive the adjusting block 3222 to move vertically up and down.

[0054] The chamber 13 is also vertically provided with a limiting rod 3223, which is located on one side of the adjusting block 3222 and is vertically slidably connected to it, in order to prevent the adjusting block 3222 from rotating together with the threaded rod 3221.

[0055] A first bevel gear 3224 is also provided at the bottom end of the threaded rod 3221;

[0056] A transmission rod 3225 is rotatably inserted on the support platform 1. One end of the transmission rod extends into the chamber 13 and is equipped with a second bevel gear 3226 that meshes with the first bevel gear 3224. When the transmission rod 3225 rotates, it drives the threaded rod 3221 to rotate through the meshing of the first bevel gear 3224 and the second bevel gear 3226.

[0057] With this design, when the clamping ring 21 needs to be adjusted, the operator rotates the transmission rod 3225. At this time, the first bevel gear 3224 and the second bevel gear 3226 mesh to drive the threaded rod 3221 to rotate. The threaded rod 3221 drives each adjusting rod 3211 to move vertically up and down through the adjusting block 3222. At the same time, the limiting rod 3223 prevents the adjusting block 3222 from rotating with the threaded rod 3221, so as to drive the telescopic ends of each support rod 313 to extend and retract until each clamping ring 21 moves to the predetermined position.

[0058] In one embodiment, the support platform 1 is provided with an indicator groove 15;

[0059] The measuring component 4 includes a set of bidirectional measuring rods 41, which consists of two measuring rods 41 that are arranged opposite to each other and slidably inserted into the corresponding clamping rings 21. Each measuring rod 41 is used to measure the pipe diameter.

[0060] Each measuring rod 41 has an indicator rod 42 vertically installed at one end near the center of the bearing platform 1. Its bottom is slidably connected to the indicator groove 15. The indicator groove 15 is also provided with a scale 43, which has bidirectional scales and is located below the indicator rod 42.

[0061] Each measuring rod 41 is also provided with an elastic unit 44 between it and the corresponding clamping ring 21, which applies a thrust to the corresponding measuring rod 41 in the direction of approaching the center of the support platform 1.

[0062] With this design, when the clamping center height of each clamping ring 21 corresponds to the center height of the pipe wall, each clamping ring 21 moves towards the pipe. Each indicator rod 42 first contacts the pipe wall. As each clamping ring 21 continues to move, each measuring rod 41 is squeezed and moves away from the center of the support frame 11 until each clamping ring 21 clamps the pipe wall. At this time, each indicator rod 42 is in close contact with the predetermined position of the pipe wall and indicates the scale 43, which makes it easy for the staff to quickly measure the pipe diameter.

[0063] Preferably, the elastic unit 44 can be a spring from the prior art.

[0064] In one embodiment, the measuring component 4 further includes a sensing unit 45 disposed in the measuring rod 41. The sensing unit 45 is signal connected to an external receiving unit (not shown in the figure), and the detection end face of the sensing unit 45 is flush with the contact surface of the corresponding indicator rod 42. When the indicator rod 42 is in contact with the pipe wall, the detection end face of the sensing unit 45 also contacts the pipe wall and performs temperature detection on it.

[0065] With this design, when the clamping ring 21 clamps the pipe wall, the detection end face of the sensing unit 45 and the indicator rod 42 are in contact with the pipe wall. As the pipe is put into operation and generates heat, the sensing unit 45 monitors the pipe wall temperature in real time and sends a signal to the receiving unit. The staff can remotely monitor the pipe wall through the receiving unit.

[0066] Preferably, the sensing unit 45 can be a temperature sensor from the prior art.

[0067] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0068] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0069] Additionally, "multiple" refers to two or more.
