[0002] Some equipment and pipeline thermal insulation construction needs to detect the thickness of the thermal insulation layer after the construction, the traditional detection method is to drill holes in the protection layer to be detected and then use measuring tools to measure, and then fill the holes, this method will cause damage to the protection layer to some extent, and it is not convenient, so it needs to be further improved. CONTENT OF THE UTILITY MODEL

[0003] In order to solve the above-mentioned problems, the present application provides a thermal insulation layer thickness measuring device.

[0004] The present application provides a thermal insulation layer thickness measuring device, which adopts the following technical scheme:

[0005] A thermal insulation layer thickness measuring device, comprising a measuring part for piercing into the thermal insulation layer and a hand-held part provided on the measuring part for holding, the end of the measuring part away from the hand-held part is provided with a sharp end, and the diameter of the measuring part is not greater than 2mm.

[0006] By adopting the above technical scheme, the staff holds the hand-held part, and the sharp end of the measuring part is perpendicular to the axis direction of the thermal insulation layer to pierce into the thermal insulation layer, when it abuts against the surface of the equipment or the outer wall of the pipeline, the outer surface of the measuring part is marked, and then the measuring tape is used for measurement to obtain the thickness of the thermal insulation layer. Since the diameter of the measuring part is less than 2mm, the aperture generated after piercing into the thermal insulation layer is small, and after the measuring part is separated, the aperture generated by piercing is filled by the elasticity of the thermal insulation layer itself at this time, the damage to the thermal insulation layer is relatively small, and the measurement method of the measuring device is relatively simple.

[0007] Preferably, the outer peripheral wall of the measuring part is provided with a scale line.

[0008] By adopting the above technical scheme, the scale line is provided to measure the thickness of the thermal insulation layer in real time, reduce the process and time spent by the measuring tape, and speed up the measurement rate.

[0009] Preferably, the hand-held part is made of a steel strip bent by carbon steel or stainless steel, and the measuring part is integrally formed with the hand-held part.

[0010] By adopting the technical scheme, the steel strip made of carbon steel or stainless steel is bent at one end to form a hand holding part, and the other end is ground to form a measuring part. The manufacturing method is simple and convenient, and the measuring device can be made on site at any time. The cost of manufacturing the device is also relatively low. Since the hardness of carbon steel or stainless steel is relatively high, it is not easy to deform during insertion into the insulation layer, thereby maintaining the accuracy of the measurement.

[0011] Preferably, the outer peripheral wall of the hand holding part is coaxially sleeved with an anti-skid sleeve.

[0012] By adopting the technical scheme, the anti-skid sleeve is provided to reduce the possibility of relative sliding when holding the hand holding part.

[0013] Preferably, the measuring part is detachably connected to the hand holding part.

[0014] By adopting the technical scheme, the measuring part will be worn out after use, which will cause errors in the measurement of the thickness of the insulation layer. Therefore, the measuring part is detachably connected to the hand holding part, so that the new measuring part can be replaced to continue the measurement, thereby reducing the measurement error and the cost of replacing the entire measuring device.

[0015] Preferably, the measuring part includes a tip segment and a straight segment arranged between the tip segment and the hand holding part, and the tip segment is detachably connected to the straight segment.

[0016] By adopting the technical scheme, the tip segment is detachably connected to the straight segment, so that the new measuring part can be replaced to continue the measurement, thereby reducing the measurement error and the cost of replacing the entire measuring part.

[0017] Preferably, it further comprises a limiting part for limiting the insertion direction of the measuring part.

[0018] By adopting the technical scheme, since the tip is not easy to insert along the direction perpendicular to the axis of the pipeline during insertion into the insulation layer, the measurement result may have errors. Therefore, the limiting part is provided to enable the tip of the measuring part to insert as vertically as possible to the axis of the pipeline, thereby improving the measurement accuracy.

[0019] Preferably, the limiting part includes a limiting plate abutting against the outer surface of the insulation layer, and the limiting plate is provided with a through hole for the sliding of the measuring part along the thickness direction of the limiting plate.

[0020] By adopting the technical scheme, after the limiting plate abuts against the outer wall of the pipeline, then the measuring part is arranged in the through hole, and then the measuring part is arranged in the through hole, so that the direction of the subsequent measuring part is limited, thereby improving the measurement accuracy.

[0021] Preferably, the limiting part further comprises two flexible bands respectively arranged on the opposite two side walls of the limiting plate.

[0022] By adopting the technical scheme, although the limiting plate directly abuts against the thermal insulation layer of the equipment outer surface, relative movement may occur, at this time, by arranging the flexible bands, due to the flexibility of the flexible bands, the equipment or pipeline is arranged around, so as to adapt to the thermal insulation layer in different states, then the end portions of the two flexible bands are knotted and fixed, due to the increase of the contact area between the flexible bands and the outer surface of the thermal insulation layer, a certain friction force can be increased, so as to limit the movement of the limiting plate, so as to reduce the possibility of deviation of the measuring part when inserted into the thermal insulation layer. After measurement, the flexible bands are also convenient to wind or arrange around the limiting plate for storage, which is convenient to carry and can reduce the space occupation.

[0023] In summary, the utility model has the following beneficial effects:

[0024] 1、the measuring device, relative to the prior art needs to drill a hole and then measure with a measuring tool, the damage to the thermal insulation layer is relatively small, and the measurement method of the measuring device is also relatively simple

[0025] 2、the measuring part is detachably connected to the handheld part, or the tip segment is detachably connected to the straight segment, so that the tip segment can be replaced after wear, thereby reducing the cost of replacing the entire measuring device.

[0026] 3、by arranging the limiting part, the tip can be as perpendicular as possible to the axis direction of the pipeline, so as to improve the measurement accuracy. BRIEF DESCRIPTION OF DRAWINGS

[0035] The present application discloses a thermal insulation layer thickness measuring device.

[0036] Embodiment 1

[0037] A thermal insulation layer thickness measuring device, referring to Figure 1 , comprises a measuring part 2 for piercing into a thermal insulation layer 1 and a handheld part 3 arranged on the measuring part 2 for holding, in the present embodiment, the measuring part 2 and the handheld part 3 are integrally formed, and are both made of a carbon steel or a stainless steel bar, the selected steel bar has a circular cross section, and the diameter of the selected steel bar should not be greater than 2 mm, so as to maintain a certain hardness and also to reduce the size of the aperture generated when piercing into the thermal insulation layer 1, thereby reducing the damage to the thermal insulation layer 1.

[0038] For the support of the measuring part 2 and the handheld part 3, a steel bar or a steel wire with a certain length is first cut, one end of which is bent according to a pliers or other hand tools, and can be circular, square or other shapes according to the requirement, so as to form the handheld part 3. The measuring part 2 is kept straight, and the end of the measuring part 2 away from the handheld part 3 is ground to be pointed, so that the measuring part 2 comprises a pointed end section 21 and a straight section 22, and the ground pointed end section 21 is used to pierce into the thermal insulation layer 1.

[0039] It should be noted that the circular diameter of the handheld part 3 is set according to the habit of the user, in order to improve the stability when pinching to pierce into the thermal insulation layer 1, the diameter of the handheld part 3 can be increased, so that the whole hand can pass through to hold the handheld part 3. For the pointed end section 21, in order to reduce the size of the aperture generated, the length of the pointed end section 21 can be increased, so as to reduce the possibility of the subsequent straight section 22 piercing into the thermal insulation layer 1.

[0040] Referring to Figure 2Further, the outer peripheral wall of the measuring part 2 is provided with a scale line 4, and a tooth-shaped mark can be sawed at a certain length interval on the scale line 4, which can be a centimeter scale; or a scale is adhered to the outer surface of the measuring part 2, which can be a millimeter scale, so as to view the thickness of the thermal insulation layer 1. The scale line 4 is set, and the tip section 21 is vertically penetrated into the thermal insulation layer 1 along the axial direction of the thermal insulation layer 1, and when the tip section 21 abuts against the surface of the equipment or the outer wall of the pipeline, a mark is made on the outer surface of the measuring part 2, and then the thickness of the thermal insulation layer 1 is measured by using a tape measure, so that the thickness of the thermal insulation layer 1 can be measured in real time, the process and time required for measuring by using a tape measure are reduced, and the measuring speed is accelerated.

[0041] Embodiment 2

[0042] With reference to Figure 3 The difference between the embodiment 1 and the embodiment 2 is that, since the tip section 21 abuts against the equipment or the pipeline, and is used for a long time, wear may occur, and the measurement of the measuring part 2 provided with the scale line 4 may be inaccurate. In this embodiment, the measuring part 2 is detachably connected to the hand-held part 3, and the detachable connection can be achieved by thread cooperation. Specifically, a screw 5 can be protruded from the outer peripheral wall of the hand-held part 3, and the measuring part 2 is provided with a thread 6 for thread cooperation of the screw 5. Figure 4 Alternatively, as shown in FIG. 2, the tip section 21 is detachably connected to the straight section 22, and the screw 5 is arranged on the tip section 21 or the straight section 22, and the other one is provided with a corresponding thread 6 for thread cooperation.

[0043] With reference to Figure 5 Further, in order to reduce the possibility of hand slipping during use, a non-slip sleeve 7 can be coaxially sleeved on the hand-held part 3, the non-slip sleeve 7 is made of silica gel, and the outer peripheral wall of the non-slip sleeve 7 is provided with non-slip lines.

[0044] Embodiment 3

[0045] With reference to Figure 6 The difference between the embodiment 1 and the embodiment 3 is that the embodiment 3 further comprises a limiting part 8 for limiting the penetration direction of the measuring part 2. Specifically, the limiting part 8 comprises a limiting plate 81 abutting against the outer surface of the thermal insulation layer 1 and two flexible bands 82 fixedly connected to the opposite two side walls of the limiting plate 81. In this embodiment, the limiting plate 81 can be provided in a rectangular shape along the thickness direction thereof, and the limiting plate 81 or the corresponding pipeline can be provided in an arc shape, which can be set according to requirements. The limiting plate 81 is provided with a through hole penetrating through the thickness direction of the limiting plate 81 and suitable for the diameter of the measuring part 2, so as to limit the penetration direction of the measuring part 2.

[0046] The flexible band 82 can be made of nylon or other flexible materials to adapt to different shaped devices or pipes of different sizes. When not in use, the flexible band 82 can be wound on the limiting plate 81 for storage. When wound on the limiting plate 81, the flexible band 82 can be arranged on the hand-held part 3 or abut against the measuring part 2 to be temporarily fixed on the limiting plate 81 for storage, reducing the difficulty of storage. To improve the contact between the flexible band 82 and the thermal insulation layer 1 and reduce the movement of the limiting plate 81, the surface of the flexible band 82 close to the thermal insulation layer 1 can be polished to form a rough surface.

[0047] It should be noted that the free ends of the two flexible bands 82 can be fixed by a live knot or a buckle such as a carabiner. The specific arrangement depends on the requirements.

[0048] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
