Description
Technical Field
[0001] This utility model relates to the field of temperature measurement technology, and in particular to a multi-head temperature measuring device. Background Technology
[0002] The bearings of existing coal mills require temperature protection to prevent damage to the equipment due to excessive bearing temperature.
[0003] Coal mills have monitoring holes. It is difficult to fix multiple monitoring elements in the monitoring holes to measure the bearing temperature using existing fasteners. Therefore, when multiple monitoring signals need to be collected, the existing technology often uses a dual temperature measuring head. The dual temperature measuring head has two temperature monitoring signal terminals inside, which can generate two monitoring signals. However, the two temperature monitoring signal terminals are integrated into a single temperature element, which can only monitor the temperature signal at the same location. The monitoring range is small and the applicability is poor. Utility Model Content

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0039] like Figures 1 to 6 As shown, this utility model provides a multi-head temperature measuring device for monitoring temperature through a monitoring hole. The multi-head temperature measuring device includes a first sleeve 1, a fastening assembly 2, a temperature monitoring element 3, and a second sleeve 4. The first sleeve 1 can be fixed to the monitoring hole. The fastening assembly 2 is provided with multiple through holes and is located at the first end of the first sleeve 1. The fastening assembly 2 is deformable. The temperature monitoring element 3 is arranged in a one-to-one correspondence with the through holes. The temperature monitoring element 3 passes through the through holes, and the monitoring end of the temperature monitoring element 3 extends out of the second end of the first sleeve 1. The second sleeve 4 has a first state detached from the first end of the first sleeve 1 and a second state connected to the first end of the first sleeve 1. When the second sleeve 4 changes from the first state to the second state, the fastening assembly 2 can be squeezed and deformed by the second sleeve 4, thereby fastening the temperature monitoring element 3. When the second sleeve 4 changes from the first state to the second state, the fastening assembly 2 can be reset to release the temperature monitoring element 3.
[0040] The first sleeve 1 can be fixed to the monitoring hole. The multi-head temperature measuring device can fix multiple temperature monitoring elements 3 through multiple through holes, and the position to be monitored can be adjusted by the insertion position of the temperature monitoring element 3. Then, the second sleeve 4 is connected to the first sleeve 1, so that the fastening component 2 locks and fixes the monitoring position, thereby facilitating the fixing of multiple temperature monitoring elements 3 in the monitoring hole, increasing the temperature monitoring range and improving applicability.
[0041] It is understandable that the aforementioned multi-head temperature measuring device can be used not only in coal mills, but also in other devices.
[0042] like Figure 1 As shown, in some embodiments, two through holes are provided, and temperature monitoring elements 3 are correspondingly provided in both through holes. In the current embodiment, the temperature monitoring element 3 includes a monitoring end and a lead wire, with the lead wire passing through the through hole. To facilitate adjustment of the position of the temperature monitoring element 3, the lead wire of the temperature monitoring element 3 is also passed through a second sleeve 4.
[0043] like Figure 3 and Figure 4 As shown, in some embodiments, the fastening assembly 2 includes an elastic element 21 and a retaining ring 22. A through hole is formed in the elastic element 21, and the retaining ring 22 is sleeved on the outer periphery of the elastic element 21. The retaining ring 22 can be compressed and deformed by the second sleeve 4, thereby causing the elastic element 21 to contract, which in turn deforms the through hole, compressing the lead wire of the temperature monitoring element 3 passing through the through hole, so as to fix it by friction. Exemplarily, the elastic element 21 may be, but is not limited to, an elastic rubber plug with a through hole.
[0044] Specifically, the retaining ring 22 includes a ring portion 221 and an extension portion 222. Multiple extension portions 222 are evenly distributed around the ring portion 221. One end of the extension portion 222 is connected to the ring portion 221, and the other end extends away from the ring portion 221. The elastic member 21 is inserted into the ring portion 221 and surrounded by multiple extension portions 222. The outer side of the extension portion 222 away from the ring portion 221 is provided with abutting protrusion 223. When the abutting protrusion 223 extends into the second sleeve 4, the second sleeve 4 can abut against the abutting protrusion 223, thereby squeezing the elastic member 21 located on the inner side and causing the elastic member 21 to deform.
[0045] like Figure 6 As shown, in order to facilitate the abutment, an inclined wall 41 is provided inside the second sleeve 4. The inclined wall 41 gradually approaches the axis of the second sleeve 4 from one end close to the first sleeve 1 to the other end. As the second sleeve 4 gets closer to the first sleeve 1, the deformation of the inclined wall 41 against the elastic member 21 is greater, and the tightness of the temperature monitoring member 3 is higher.
[0046] In the current embodiment, the inclined wall 41 is an annular wall, and the inclined wall 41 forms a trumpet shape, so that the force on the elastic member 21 is more uniform.
[0047] like Figure 2 and Figure 6As shown, in some embodiments, to facilitate the fixing between the first sleeve 1 and the second sleeve 4, the first sleeve 1 is provided with a first external thread 12, and the second sleeve 4 is provided with a first internal thread 42 that mates with the first external thread 12. The inclined wall 41 is located on the side of the first internal thread 42 away from the port of the second sleeve 4. During connection, the ring clamp 221 is first inserted into the first sleeve 1, so that the extension 222 protrudes outside the first sleeve 1. Then, the second sleeve 4 is screwed onto the first sleeve 1 through the first external thread 12 and the first internal thread 42. During tightening, the inclined wall 41 abuts against the extension 222, causing the extension wall to compress the elastic element 21. When the position of the temperature monitoring element 3 needs to be adjusted midway, simply loosen the second sleeve 4 and then forcefully push and pull the lead wire of the temperature monitoring element 3.
[0048] like Figure 5 As shown, in some embodiments, to reduce the movement of the ring clamp 221 when it is inserted into the first sleeve 1 and to reduce the possibility of the extension 222 entering the first sleeve 1 excessively, a first step 11 is provided inside the first sleeve 1, and the ring clamp 221 abuts against the first step 11. It is understood that the ring clamp 221 can be interference-fitted with the first sleeve 1 to further improve stability.
[0049] In some alternative embodiments, the clamp may be replaced by a spring clip.
[0050] like Figure 1 As shown, in some embodiments, to prevent the monitoring end of the temperature monitoring element 3 from entering the first sleeve 1 during adjustment, and to avoid interference from the first sleeve 1, the temperature monitoring element 3 is provided with a second step 31 in the current embodiment. The multi-head temperature measuring device also includes a limiting piece 5, which has a second through hole through which the lead wire of the temperature monitoring element 3 passes. The second step 31 can abut against the side of the limiting piece 5 away from the first sleeve 1, and the limiting piece 5 can abut against the first end port of the first sleeve 1, thereby restricting the monitoring end of the temperature monitoring element 3 from entering the first sleeve 1. Exemplarily, the size of the limiting piece 5 can be larger than the size of the first end port of the first sleeve 1.
[0051] like Figure 1As shown, in some embodiments, the multi-head temperature measuring device further includes a spring 6, which is configured one-to-one with the temperature monitoring element 3. The spring 6 is sleeved on the lead wire of the temperature monitoring element 3 and clamped between the limiting plate 5 and the second step 31. Thus, when the monitoring end of the temperature monitoring element 3 excessively presses against the limiting plate 5, the spring 6 can accumulate a large potential energy. The potential energy of the spring 6 can cause the monitoring end of the temperature monitoring element 3 to move slightly away from the limiting plate 5, thereby reducing the continuous pressing of the monitoring end of the temperature monitoring element 3 against the limiting plate 5 and extending its service life. Furthermore, the spring 6 allows the temperature monitoring element 3 to quickly reset after the second sleeve 4 is loosened. Thus, when not in use, the monitoring end of the temperature monitoring element 3 can be disengaged from the limiting plate 5 without adjustment, thereby extending its service life.
[0052] like Figure 1 As shown, in some embodiments, the first sleeve 1 is provided with a second external thread 13, so that a second internal thread that cooperates with the second external thread 13 can be provided in the monitoring hole, so as to facilitate the screwing of the first sleeve 1 into the monitoring hole and reduce the connection difficulty. Of course, in other alternative embodiments, the first sleeve 1 can also be welded to seal the monitoring hole.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
