Description

Technical Field

[0001] This utility model belongs to the field of escalator technology, and in particular relates to an escalator chain temperature detection device. Background Technology

[0002] With the vigorous development of China's rail transit construction industry, the number of escalators in use is increasing daily, and their safety is receiving more and more attention. Escalators generally operate around the clock, with the chains running under high intensity continuously. If the operating environment is harsh or lubrication and sealing are inadequate, hinge wear can occur. Once the chain hinges wear down, it can easily cause teeth to skip or the chain to detach during operation, reducing the chain's lifespan, accelerating chain failure, and in severe cases, causing safety problems such as chain breakage.

[0003] Currently, escalator chain lubrication is typically achieved manually by applying lubricant at regular intervals and in measured amounts, or by using devices such as thermal imaging probes to collect temperature values ​​generated by chain friction. The lubrication status of the chain is then determined based on the collected temperature values, and lubrication is applied accordingly. However, thermal imaging probes are generally fixedly installed on the escalator and located on one side of the chain. The fixed angle of the thermal imaging probe sometimes makes it difficult to accurately align it with the chain being tested. Utility Model Content

[0004] The purpose of this invention is to provide an escalator chain temperature detection device that can adjust the illumination angle of the thermal imaging probe so that the thermal imaging probe can be better aligned with the chain being detected.

[0013] Furthermore, it also includes a third bolt and a fourth bolt. The bracket includes a second horizontal plate and a second vertical plate. The second vertical plate is vertically mounted on one end of the second horizontal plate. The second horizontal plate has a second through hole and a second arc-shaped hole. The second through hole is located at the center of the arc of the second arc-shaped hole. The first horizontal plate has a third through hole and a fourth through hole.

The third bolt passes through the third through hole and the second through hole in sequence and is threaded with a third nut. The fourth bolt passes through the fourth through hole and the second arc-shaped hole and is threaded with a fourth nut.

[0026] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the escalator chain temperature detection device of this utility model. Figure 2 This diagram illustrates the installation of the escalator chain temperature detection device of this utility model on an escalator. Figure 3 for Figure 2 Enlarged schematic diagram of part A. An escalator chain temperature detection device includes a first vertical plate 1, a locking mechanism, a first horizontal plate 2, a bracket, and a thermal imaging probe 3. The first vertical plate 1 is vertically rotatably mounted on the escalator. The locking mechanism is mounted on the escalator for locking or releasing the first vertical plate 1. The first horizontal plate 2 is vertically mounted on the top of the first vertical plate 1. The bracket is mounted on the first horizontal plate 2 in an adjustable manner. The thermal imaging probe 3 is mounted on the second bracket.

[0027] In use, the escalator chain temperature detection device of this utility model involves installing a first vertical plate 1 on the escalator, thereby mounting the thermal imaging probe 3 on one side of the chain 17 to be detected. The horizontal angle at which the thermal imaging probe 3 illuminates the chain 17 can be adjusted by adjusting the mounting position of the bracket on the first horizontal plate 2. The first vertical plate 1 can be released via a locking mechanism, and then its vertical angle can be adjusted by vertically rotating it. After adjustment, the position of the first vertical plate 1 is fixed by the locking mechanism, thus adjusting the illumination angle of the thermal imaging probe 3 to better align it with the chain 17. The temperature of the chain 17 can then be measured using the thermal imaging probe 3.

[0028] In one embodiment, the escalator chain temperature detection device of this utility model further includes a first bolt 4 and a second bolt 5. A first through hole and a first arc-shaped hole 6 are provided on the first vertical plate 1. The first through hole is located at the center of the arc of the first arc-shaped hole 6. One end of the first bolt 4 and the second bolt 5 are fixedly mounted on the escalator, and the other end of the first bolt 4 and the second bolt 5 pass through the first through hole and the first arc-shaped hole 6, respectively. The locking mechanism includes a first nut 7 and a second nut 8, which are threadedly connected to the first bolt 4 and the second bolt 5, respectively. When it is necessary to adjust the vertical angle of the first vertical plate 1, the first nut 7 and the second nut 8 are first turned so that the first nut 7 and the second nut 8 are disengaged from the first vertical plate 1. At this time, the first vertical plate 1 can be vertically rotated with the first bolt 4 passing through the first through hole as the center, thereby adjusting the angle of the thermal imaging probe 3 illuminating the detected chain 17 in the vertical direction. When the first vertical plate 1 is rotated, the second bolt 5 moves along the first arc-shaped hole 6 within the first arc-shaped hole 6. The cooperation between the second bolt 5 and the first arc-shaped hole 6 restricts the vertical rotation angle of the first vertical plate 1. After the angle of the first vertical plate 1 is adjusted, the first nut 7 and the second nut 8 are tightened, causing both nuts 7 and 8 to abut against the first vertical plate 1, pressing the first vertical plate 1 firmly onto the escalator and fixing its position. Furthermore, the contact between the first nut 7 and the second nut 8 and the first vertical plate 1 ensures a more stable fixation to the escalator, preventing slippage.

[0029] In one embodiment, the escalator chain temperature detection device of this utility model further includes a third bolt 9 and a fourth bolt 10. The bracket includes a second horizontal plate 11 and a second vertical plate 12. The second vertical plate 12 is vertically disposed on one end of the second horizontal plate 11. The second horizontal plate 11 has a second through hole and a second arc-shaped hole 13. The second through hole is located at the center of the arc of the second arc-shaped hole 13. The first horizontal plate 2 has a third through hole and a fourth through hole. The distance between the third through hole and the fourth through hole is equal to the distance between the second through hole and the second arc-shaped hole 13. The third bolt 9 passes through the third through hole and the second through hole in sequence and is threadedly connected to a third nut 14. The fourth bolt 10 passes through the fourth through hole and the second arc-shaped hole 13 and is threadedly connected to a fourth nut 15. The thermal imaging probe 3 is disposed on the side of the second vertical plate 12 away from the second horizontal plate 11. When adjusting the installation position of the second horizontal plate 11 on the first horizontal plate 2, first loosen the third nut 14 and the fourth nut 15. At this point, the second horizontal plate 11 can rotate horizontally around the third bolt 9 passing through the second through hole, thereby adjusting the angle at which the thermal imaging probe 3 illuminates the inspected chain 17. While rotating the second horizontal plate 11, the fourth bolt 10 moves along the second arc-shaped hole 13. The engagement of the fourth bolt 10 and the second arc-shaped hole 13 restricts the horizontal rotation angle of the second horizontal plate 11. After the angle of the second horizontal plate 11 is adjusted, loosen the third nut 14 and the fourth nut 15 so that they both abut against the second horizontal plate 11, pressing the second horizontal plate 11 firmly onto the first horizontal plate 2 and fixing its installation position. Furthermore, the third nut 14 and the fourth nut 15 are used to abut against the fourth horizontal plate, making the connection between the second horizontal plate 11 and the first horizontal plate 2 more stable and preventing the second horizontal plate 11 from moving.

[0030] In one embodiment, the bracket further includes a third horizontal plate 16, which is vertically disposed at the top of the second vertical plate 12, and forms a Z-shape between the third horizontal plate 16, the second vertical plate 12, and the second horizontal plate 11. The third horizontal plate 16 is located above the thermal imaging probe 3, serving to protect the thermal imaging probe 3.

[0031] In one embodiment, the thermal imaging probe 3 and the second vertical plate 12 are connected by bolts. This arrangement facilitates the disassembly and assembly of the thermal imaging probe 3, allows for better handling of the thermal imaging probe 3 or its support, prevents debris from impacting the thermal imaging probe 3, and avoids dust accumulation on top of the thermal imaging probe 3, which could damage it.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
