Description

Technical Field

[0001] This utility model relates to the field of instrument installation technology, and in particular to an auxiliary device for the installation of metallurgical instruments. Background Technology

[0002] Metallurgical instruments are specialized instruments used in the metallurgical field to accurately measure, monitor, and control key parameters such as temperature, pressure, flow rate, liquid level, material level, and composition in the metallurgical process. These instruments ensure the efficient, safe, and stable operation of metallurgical production.

[0003] Metallurgical instruments are generally installed on the outer wall of the equipment so that workers can observe the data. Metallurgical equipment is large in size, and it is difficult to use auxiliary tools to position and install instruments on it, making the installation of metallurgical instruments quite troublesome.

[0004] To address the aforementioned issues, we propose an auxiliary device for the installation of metallurgical instruments. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary device for the installation of metallurgical instruments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A metallurgical instrument installation auxiliary device includes a metallurgical instrument positioning component and a fixing component. The fixing component includes an adsorption cover, on both sides of which a sleeve and a slide cylinder are fixedly installed. The slide cylinder is connected to the inner side of the adsorption cover. A piston valve is slidably installed on the inner side of the slide cylinder. A connecting rod is fixedly installed on the side of the piston valve. A limit groove is formed on the connecting rod. A cover is screwed to the end of the slide cylinder. The connecting rod slides through to the outside of the cover. A shaft seat is fixedly installed on the cover. A rotating shaft is rotatably installed on the shaft seat. A torque return spring is fixedly installed between the rotating shaft and the shaft seat. A limit lever is fixedly installed on the rotating shaft. The lower end of the limit lever is engaged with the limit groove.

[0008] Furthermore, the cap is provided with air holes.

[0009] Furthermore, a sealing ring is fixedly installed at the port of the adsorption hood.

[0010] Furthermore, a limit strip is fixedly installed on the outer wall of the connecting rod, and a pull cap is fixedly installed on the outer end of the connecting rod.

[0011] Furthermore, the metallurgical instrument positioning assembly includes a metallurgical instrument positioning ring, on both sides of which slide rods are symmetrically fixedly installed, and the slide rods are slidably inserted into the inner side of the sleeve.

[0012] Furthermore, a limiting screw is screwed onto the side wall of the sleeve, the limiting screw being screwed through the sleeve and the inner end of the limiting screw abutting against the slide rod.

[0013] Furthermore, a rubber sleeve is fixedly installed on the inner side of the metallurgical instrument positioning ring.

[0014] Compared with related technologies, the metallurgical instrument installation auxiliary device proposed in this utility model has the following beneficial effects:

[0015] In this utility model, a metallurgical instrument installation auxiliary device is provided. The fixing component utilizes the principle of vacuum adsorption, which allows the adsorption cover to adhere to the outer wall of the metallurgical equipment through vacuum adsorption. The two adsorption covers on both sides are used for adsorption and positioning, so that the metallurgical instrument positioning ring in the middle can be relatively stably set on the outside of the installation position, which facilitates the subsequent installation of the instrument.

[0016] In addition, this utility model features a combination design of a sliding cylinder and a piston valve on the side of the adsorption hood. By pulling the connecting rod, the piston valve can be moved. When the piston valve is pulled outward, the communication space between it and the inside of the adsorption hood increases, thereby reducing the air pressure inside the adsorption hood and allowing the adsorption hood to be stably adsorbed onto the outer wall of the metallurgical equipment. Conversely, when the piston valve is pushed inward, the communication space between it and the inside of the adsorption hood decreases, thereby increasing the air pressure inside the adsorption hood and facilitating the removal of the adsorption hood from the outer wall of the equipment. This makes the positioning, installation, and disassembly of the device extremely convenient and enhances its practicality. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-5 A metallurgical instrument installation auxiliary device includes a metallurgical instrument positioning component 1 and a fixing component 2. The fixing component 2 includes an adsorption cover 21, on which a sleeve 23 and a slide cylinder 25 are fixedly installed respectively on both sides. The slide cylinder 25 is connected to the inner side of the adsorption cover 21. A piston valve 26 is slidably installed on the inner side of the slide cylinder 25. A connecting rod 27 is fixedly installed on the side of the piston valve 26. A limit groove 210 is opened on the connecting rod 27. A cover 211 is screwed to the end of the slide cylinder 25. The connecting rod 27 slides through to the outside of the cover 211. A bearing seat 213 is fixedly installed on the cover 211. A rotating shaft 214 is rotatably installed on the bearing seat 213. A torque return spring 215 is fixedly installed between the rotating shaft 214 and the bearing seat 213. A limit lever 216 is fixedly installed on the rotating shaft 214. The lower end of the limit lever 216 is engaged with the limit groove 210.

[0025] With the above-described configuration, the torque return spring 215 provides torque, causing the limit lever 216 to tend to flip downwards. This allows the limit lever 216 to engage with the inner side of the limit groove 210, thereby limiting the sliding freedom of the connecting rod 27. This fixes the position of the piston valve 26 inside the slide cylinder 25, ensuring that the volume of the communication space between the inner side of the slide cylinder 25 and the inner side of the adsorption hood 21 remains unchanged. This stabilizes the air pressure inside the adsorption hood 21, allowing the adsorption hood 21 to be stably adsorbed onto the outer wall of the metallurgical equipment.

[0026] In this method, the cap 211 has an air hole 212.

[0027] By setting it up in the above way, the opening of the air hole 212 avoids the generation of air pressure in the outer area of ​​the piston valve 26, thereby increasing the resistance to pulling the connecting rod 27.

[0028] In this method, a sealing ring 22 is fixedly installed at the port of the adsorption cover 21.

[0029] By setting it in the above manner, the sealing ring 22 ensures the airtightness of the adsorption cover 21 during adsorption, thereby ensuring its stable adsorption effect. At the same time, the sealing ring 22 is made of rubber and also has lateral anti-slip properties, preventing the adsorption cover 21 from sliding laterally during adsorption.

[0030] In this method, a limit strip 28 is fixedly installed on the outer wall of the connecting rod 27, and a pull cap 29 is fixedly installed on the outer end of the connecting rod 27.

[0031] With the above-described configuration, the pull cap 29 is designed to facilitate the movement of the connecting rod 27 by holding the pull cap 29.

[0032] In this method, the metallurgical instrument positioning component 1 includes a metallurgical instrument positioning ring 11, with slide rods 13 symmetrically fixed on both sides of the metallurgical instrument positioning ring 11. The slide rods 13 are slidably inserted into the inner side of the sleeve 23, and a rubber collar 12 is fixedly installed on the inner side of the metallurgical instrument positioning ring 11.

[0033] With the above-described configuration, the metallurgical instrument positioning ring 11 is used for positioning the instrument during installation. The rubber sleeve 12 installed on its inner side prevents the inner wall of the metallurgical instrument positioning ring 11 from scratching the instrument. In addition, the sliding relationship between the sliding rods 13 on both sides of the metallurgical instrument positioning ring 11 and the sleeve on the fixing component 2 allows the metallurgical instrument positioning ring 11 to adjust its position by sliding, which facilitates the adjustment of the positioning position of the metallurgical instrument positioning ring 11.

[0034] In this method, a limiting screw 24 is screwed onto the side wall of the sleeve 23. The limiting screw 24 is screwed through the sleeve 23 and the inner end of the limiting screw 24 abuts against the slide rod 13.

[0035] By setting it in the above manner, tightening the limiting screw 24 so that its inner end abuts against the slide rod 13, thereby restricting the sliding freedom of the slide rod 13 inside the sleeve 23, and at this time the position adjustment and fixation of the metallurgical instrument positioning ring 11 located in the middle is completed.

[0036] The working principle of the metallurgical instrument installation auxiliary device provided by this utility model is as follows:

[0037] During use, align the port of the adsorption hood 21 with the predetermined instrument installation position on the outer wall of the metallurgical equipment, ensuring a tight fit between the adsorption hood 21 and the outer wall. Ensure the sealing ring 22 at the port of the adsorption hood 21 is in full contact with the outer wall to guarantee good airtightness. Hold the pull cap 29 and pull the connecting rod 27 outwards. The connecting rod 27 drives the piston valve 26 to slide outwards within the slide cylinder 25. Since the slide cylinder 25 is connected to the inside of the adsorption hood 21, the outward sliding of the piston valve 26 increases the internal space of the adsorption hood 21, reducing the air pressure and creating a negative pressure. When the connecting rod 27 is pulled to the appropriate position, causing the adsorption hood 21 to generate sufficient adsorption force, the limit lever 216, under the action of the torque return spring 215, flips downwards and engages in the limit groove 210 on the connecting rod 27, restricting the sliding freedom of the connecting rod 27, thereby positioning the piston valve 26. The negative pressure inside the adsorption hood 21 is kept stable and firmly adsorbed onto the outer wall of the metallurgical equipment. Following the above steps, another adsorption hood 21 of the fixing component 2 is installed symmetrically on the other side of the outer wall of the metallurgical equipment, so that the two adsorption hoods 21 are set opposite each other. The position of the metallurgical instrument positioning ring 11 is precisely adjusted by sliding the position of the slide rod 13 inside the sleeve 23, so that it is accurately aligned with the instrument mounting hole on the metallurgical equipment. After the metallurgical instrument positioning ring 11 is adjusted to the appropriate position, the limiting screw 24 on the side wall of the sleeve 23 is tightened, so that the inner end of the limiting screw 24 abuts against the slide rod 13, restricting the sliding freedom of the slide rod 13 inside the sleeve 23, thereby fixing the position of the metallurgical instrument positioning ring 11. Subsequently, the instrument can be installed according to the positioning position of the metallurgical instrument positioning ring 11.
