Abstract
Description
Technical Field
[0001] This utility model relates to the field of installation technology of temperature measuring resistance thermometers on grate plates, and in particular to an installation device for temperature measuring resistance thermometers on grate plates. Background Technology
[0002] In the cement industry, the temperature of some grate plates in the fourth-generation grate cooler needs to be monitored online in real time, but there is no matching installation device between the temperature measuring resistance and the grate plate.
[0003] A search revealed a grate with publication number CN203115485U, comprising an upper grate, a lower grate, a support rod, and a venting groove. The upper and lower grates are connected by a connecting rod, with the support rod positioned between them. The venting groove is located in the middle of the support rod. This design is unique and simple to use. The support rod between the upper and lower grates enhances the grate's robustness and increases its service life. However, currently, the installation of temperature measuring resistors on such grates mainly involves on-site welding of the resistor brackets. Due to limitations in on-site construction conditions, it is difficult to install the temperature measuring resistors properly, leading to inaccurate data collection, resistor detachment, and even potential damage to the resistors during welding or removal when replacing the grate. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a grate plate temperature measuring resistor installation device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A temperature measuring resistor mounting device for a grate includes an upper grate, a lower grate, a mounting base, and a temperature measuring resistor body. The lower grate includes two grate blades with a gap between them. The mounting base is located in the gap between the two grate blades and includes a steel pipe. A U-shaped bracket and a nut are fixedly connected to the top and bottom of the steel pipe, respectively. The U-shaped bracket engages with the two grate blades. A first through hole is formed at the center of the upper surface of the U-shaped bracket. A gasket is provided at the bottom of the lower grate, and a second through hole is formed on the upper surface of the gasket. The temperature measuring resistor body includes a metal resistor. The outer side of the metal resistor is integrally formed with threads, and the metal resistor is connected to the nut through the threads. A hexagonal block is integrally formed at the bottom of the metal resistor, and a lead wire is provided at the bottom of the hexagonal block.
[0007] As a further embodiment of this utility model, the center of the first through hole is concentric with the center of the steel pipe and the center of the nut.
[0008] As a further embodiment of this invention, the diameters of the first through hole and the second through hole are greater than the outer diameter of the metal resistor and less than the outer diameter of the hexagonal block.
[0009] As a further embodiment of this utility model, the bending angles of the two sides of the U-shaped card holder are the same as the bending angles of the grate blades, so that the two side bends of the U-shaped card holder fit into the grate blades.
[0010] As a further improvement of this utility model, a gap of 2 to 5 mm is left between the mounting base and the gasket.
[0011] As a further embodiment of this utility model, it also includes two inserts, both of which are fixedly connected to the upper surface of the gasket. The bottom of the lower grate has two insertion holes aligned with the inserts. Two rubber balls are symmetrically fixedly connected to the outer sides of the two inserts. Two symmetrically distributed arc-shaped slots are provided in the insertion holes.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. By setting up the mounting base, first install the mounting base in the gap between the two grate blades of the lower grate using a U-shaped clip. Then, pass the temperature measuring resistor body through the second through hole on the gasket and through the nut, steel pipe, and first through hole. Finally, lock the temperature measuring resistor body with the nut using threads, so that the temperature measuring resistor body contacts the upper grate for temperature measurement. This completes the installation of the temperature measuring resistor, making it easy for workers to disassemble and install the temperature measuring resistor, saving time and improving efficiency.
[0014] 2. By using the rubber ball and the arc-shaped groove together, the gasket is attached to the lower grate plate, and the insert on the gasket is inserted into the insertion hole. The rubber ball is then inserted into the arc-shaped groove to help fix the gasket, thereby positioning the gasket and ensuring that the center of the second through hole is concentric with the center of the first through hole. At the same time, the temperature measuring resistor can be installed without the operator holding the gasket, which improves the convenience of temperature measuring resistor installation.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Reference Figures 1-3A temperature measuring resistor mounting device for a grate includes an upper grate 1, a lower grate 2, a mounting base 6, and a temperature measuring resistor body 7. The upper grate 1 and the lower grate 2 have the same shape and specifications, and are connected at their rear sides by a steel plate. The lower grate 2 includes two grate blades with a gap between them. The mounting base 6 is located in the gap between the two grate blades and includes a steel pipe 11. A U-shaped bracket 10 and a screw are welded to the top and bottom ends of the steel pipe 11, respectively. The nut 9 and U-shaped bracket 10 are engaged with the two grate blades. A first through hole 12 is located at the center of the upper surface of the U-shaped bracket 10. A gasket 8 is placed at the bottom of the lower grate 2, and a second through hole 13 is located on the upper surface of the gasket 8. The temperature measuring resistor body 7 passes through the second through hole 13, nut 9, steel pipe 11, and U-shaped bracket 10 to contact the upper grate 1. The temperature measuring resistor body 7 includes a metal resistor 14, with an integrally formed thread 15 on the outer side of the metal resistor 14. The metal resistor 14 is connected to the nut 9 via a thread 15. A hexagonal block 16 is integrally formed at the bottom of the metal resistor 14, and a lead wire 17 is provided at the bottom of the hexagonal block 16. The temperature measuring resistor body 7 is model WZP-291. First, the mounting base 6 is installed in the gap between the two grate blades of the lower grate 2 via a U-shaped clip 10. Then, the temperature measuring resistor body 7 is passed through the second through hole 13 of the gasket 8 and through the nut 9, steel pipe 11, and first through hole. 12. Then, the staff presses the gasket 8 with their hand to make the gasket 8 fit against the lower grate plate 2. Then, the temperature measuring resistor body 7 is tightened by the engagement of the thread 15 and the nut 9, so that the mounting base 6 and the gasket 8 are tightened together, thus firmly fixing the temperature measuring resistor body 7 on the grate plate. At the same time, the metal resistor body 14 of the temperature measuring resistor body 7 will contact the upper grate plate 1 to realize the temperature measurement of the grate plate. This makes it easy for the staff to disassemble and install the temperature measuring resistor, saving time and improving efficiency.
[0023] In this utility model, the center of the first through hole 12 is concentric with the center of the steel pipe 11 and the center of the nut 9, ensuring that the temperature measuring resistor body 7 can smoothly pass through the nut 9, the steel pipe 11 and the first through hole 12. The diameter of the first through hole 12 and the second through hole 13 is larger than the outer diameter of the metal resistor body 14 and smaller than the outer diameter of the hexagonal block 16. The bending angle of the two sides of the U-shaped bracket 10 is the same as the bending angle of the grate blade, so that the two sides of the U-shaped bracket 10 are in contact with the grate blade, thereby enabling the U-shaped bracket 10 to engage with the grate blade, thereby realizing the installation of the mounting base 6. A 4mm gap is left between the mounting base 6 and the gasket 8.
[0024] The working principle of this embodiment is as follows: When installation is required, the U-shaped bracket 10 on the mounting base 6 is aligned with the gap between the two grate blades of the lower grate plate 2. The mounting base 6 is then inserted into the gap between the two grate blades. The mounting base 6 is then rotated so that the U-shaped bracket 10 rotates within the gap between the upper grate plate 1 and the lower grate plate 2, until it is staggered with the lower grate plate 2. The mounting base 6 is then moved downwards so that the lower grate plate 2 is engaged with the U-shaped bracket 10, thus securing the mounting base 6. Finally, the temperature measuring resistor body 7 is passed through the gasket 8. The second through hole 13 allows the temperature measuring resistor body 7 to pass through the nut 9, steel pipe 11, and first through hole 12. Then, the worker presses the gasket 8 with their hand to make the gasket 8 fit against the lower grate plate 2. Then, the temperature measuring resistor body 7 is tightened by the engagement of the thread 15 and the nut 9, so that the mounting base 6 and the gasket 8 are tightened together, thus firmly fixing the temperature measuring resistor body 7 on the grate plate. At the same time, the metal resistor body 14 of the temperature measuring resistor body 7 will contact the upper grate plate 1 to realize the temperature measurement of the grate plate. This makes it easy for the worker to disassemble and install the temperature measuring resistor, saving time and improving efficiency.
[0025] Example 2
[0026] Reference Figure 4 A temperature measuring resistor mounting device for a grate plate includes two inserts 19, both of which are welded to the upper surface of a gasket 8. Two insertion holes 20 are provided at the bottom of the lower grate plate 2, which are aligned with the inserts 19 and can be inserted into the insertion holes 20. Two rubber balls 18 are symmetrically bonded to the outer sides of the two inserts 19. Two symmetrically distributed arc-shaped slots 21 are provided in the insertion holes 20, and the rubber balls 18 can be engaged with the arc-shaped slots 21.
[0027] The working principle of this embodiment is as follows: When installing the temperature measuring resistor body 7, the gasket 8 can be moved upward first, so that the gasket 8 is in contact with the bottom of the lower grate plate 2. During the upward movement of the gasket 8, the insert 19 on the gasket 8 will be inserted into the insertion hole 20, and at the same time, the rubber ball 18 will be squeezed and deformed. When the gasket 8 is in contact with the lower grate plate 2, the rubber ball 18 will recover and be inserted into the arc-shaped groove 21, thereby assisting in fixing the gasket 8 and positioning the gasket 8 to ensure that the center of the second through hole 13 is concentric with the center of the first through hole 12. Then, the temperature measuring resistor body 7 can be installed by passing through the second through hole 13. The temperature measuring resistor can be installed without the operator holding the gasket 8, which improves the convenience of temperature measuring resistor installation.
[0028] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
