Description

Background Art

[0002] The plug-in high-temperature explosion-proof combustible gas detector is widely used in high-temperature environments in industries such as steel, chemical engineering, and power generation to monitor the concentration of combustible gases and ensure production safety. The instrument inserts the probe part into the measured high-temperature environment, and the transition joint plays a buffering role, while the main body of the instrument undertakes the detection and display functions. The entire instrument needs to be firmly installed at the detection point through a fixed bracket.

[0003] When installing this type of detector, the probe needs to be accurately inserted into the installation hole pre-opened by the client, and at the same time, it is necessary to ensure that the main body of the instrument faces the staff directly for easy observation of the display data. This requires the positions of the installation hole and the detector to be accurately aligned and fixed. However, in the prior art, there is a lack of a convenient tooling device that can meet the above two requirements simultaneously.

[0004] The traditional installation method requires manual alignment and positioning, which is cumbersome and inefficient. If the position deviation is too large, it will not only affect the reading accuracy but also may cause the probe to not be fully inserted or the viewing angle of the instrument to be poor. In addition, the installation operation in a high-temperature environment also poses certain safety hazards to the operators.

[0005] Therefore, providing a tooling device that can conveniently and quickly achieve the installation and positioning of the plug-in high-temperature explosion-proof combustible gas detector and center the meter head correctly has important theoretical significance and application value.

[0029] The technical solutions (including the preferred technical solutions) of the present utility model will be further described in detail below by way of the drawings and by listing some optional embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0030] Embodiment 1

[0031] As Figures 1-4 shown, the tooling for installing an inserted high-temperature explosion-proof combustible gas detector disclosed by the present utility model mainly consists of a first connecting member 1, a second connecting member 2, a nut 4, a flat washer 5, and a combustible gas detector 3.

[0032] The first connecting member 1 is a round rod, with a limiting boss 11 extending radially in the middle and an external thread on the outer peripheral surface for threaded connection with the nut 4. A flat washer 5 is also provided between the nut 4 and the limiting boss 11 to increase the friction force.

[0033] The second connecting member 2 is a disc-shaped member with a round hole in the middle. The diameter of the round hole is smaller than the outer diameter of the limiting boss 11. Therefore, the second connecting member 2 can be axially limited along the first connecting member 1, but can rotate or be locked circumferentially around the axis.

[0034] Multiple groups of connecting holes 21 are provided on the outer peripheral surface of the second connecting member 2. The positions and sizes of each group of connecting holes 21 match a group of mounting holes on the fitting to be installed. According to actual requirements, multiple second connecting members 2 can also be used, with a group of corresponding connecting holes 21 provided on each of them.

[0035] The probe part of the combustible gas detector 3 is fixedly connected to one end of the first connecting member 1, and the meter head 31 and the display unit 32 are also fixed at this end. External threads can also be provided at the other end of the first connecting member 1 for connection with the detector 3.

[0036] The present utility model can adopt the following two installation methods according to the specific on-site situation:

[0037] 1. First, for its mounting hole group, and then calibrate the combustible gas detector 3: First, loosen the nut to ensure that the second connecting member 2 can rotate relative to the first connecting member 1. Rotate the second connecting member 2 to align the connecting holes 21 thereon with the mounting hole group on the fitting to be installed, and then fix the two by bolts. Then, manually rotate the first connecting member 1 to ensure that the probe of the detector is centered. Finally, tighten the nut 4 to lock and fix all components to form an integral structure.

[0038] 2. First, calibrate the combustible gas detector 3, and then for its mounting hole group, and align the on-site mounting hole group through the second connecting member 2: First, ensure that the probe of the detector is centered. Then, when aligning the client mounting hole group based on on-site installation requirements, use an adjustable wrench to loosen the nut and thus loosen the second connecting member 2. Adjust the second connecting member 2 to align the mounting holes on the second connecting member 2 with the client mounting hole group. After alignment, use screws to fix the second connecting member 2, and finally use an adjustable wrench to tighten the nut to clamp the second connecting member 2. The position of the meter head is not affected during the entire adjustment process.

[0039] The tooling of the utility model is designed compactly and practically, which can complete the installation, alignment and fixation of the detector quickly and efficiently, improve the work efficiency and detection accuracy, avoid many defects of traditional manual operation, and has good practical value.

[0040] Embodiment 2

[0041] This embodiment is a further improvement based on Embodiment 1, and a second connecting member 2 with a multi-stage connection hole group can be adopted.

[0042] The second connecting member 2 is a relatively large disc, the outer periphery of which is divided into multiple regions, and a set of connection holes 21 are provided on each region. The sizes, spacings and arrangements of the connection holes 21 in different regions are all different. Such a design enables a single second connecting member 2a to adapt to various installation hole groups with different forms and sizes.

[0043] During use, only need to rotate the second connecting member 2 and align a suitable set of connection holes 21 with the installation hole group of the fitting to be installed, thus having better versatility and adaptability. Other components and operation steps are the same as those in Embodiment 1.

[0044] Those skilled in the art of the relevant technical field can easily understand that the above are only the preferred embodiments of the utility model, and do not limit the utility model. Any modifications, combinations, substitutions, improvements, etc. made under the spirit and principle of the utility model are all included in the protection scope of the utility model.
