Description
Technical Field
The utility model belongs to wheel pair overhauls the field, concretely relates to bearing recognition device of wheel pair.
Background
The wheel set is the part of the rolling stock contacting with the steel rail and consists of two wheels firmly pressed on the same axle. The wheel pair is used to ensure the running and steering of the rolling stock on the rail, bear all static and dynamic loads from the rolling stock, transfer the static and dynamic loads to the rail and transfer the loads generated by the irregularity of the lines to the parts of the rolling stock. After a period of operation, the wheelsets need to be removed from the locomotive and then reinstalled on the locomotive for maintenance.
One of the most important tasks in the repair of wheelsets is the replacement of the bearings at both ends of the wheelset. However, because the damage conditions of different bearings are different, some bearings are damaged and need to be replaced immediately, while some bearings may only have slight abrasion and do not need to be replaced. Therefore, after the wheel set enters the maintenance workshop, the wheel set needing to replace the bearing and the wheel set not needing to replace the bearing need to be identified (the bearing of the wheel set needing to be replaced is already detached from the wheel set before entering the maintenance workshop), so that the wheel set under different conditions enters different moving routes.
SUMMERY OF THE UTILITY MODEL
The utility model provides a bearing recognition device of wheel pair, whether install the bearing on its aim at discernment wheel pair.
In order to achieve the above object, the utility model provides a bearing identification device of wheel pair, including identification mechanism and installation component, the installation component is built with the discernment region, the discernment region is used for supplying the shaft to get into, identification mechanism install in the discernment region is used for discerning whether the shaft installs the bearing.
When the wheel pair enters the identification area, the identification mechanism in the identification area can automatically distinguish the wheel pair. The wheel set with the bearing and the wheel set without the bearing are respectively conveyed into different conveying tracks, so that different treatments are carried out.
Further, the identification mechanism in the first aspect is specifically a code reader, and the code reader can read the information code at the axle end of the axle, so as to distinguish different wheel sets (the information codes of the wheel set with the bearing removed and the wheel set without the bearing removed are respectively stored in the system before entering the identification area).
Further, the identification mechanism in the second scheme comprises a top code reader and a side code reader, and the top code reader and the side code reader are both installed in the identification area. When the wheel pair enters the identification area, the identification mechanism starts to work. The top code reader in the identification mechanism is used for reading the side information code of the wheel shaft, and the side code reader is used for reading the shaft end information code of the wheel shaft. When the top code reader and the side code reader in the identification mechanism respectively read the side information code and the shaft end information code of the wheel pair, the bearing of the wheel pair is disassembled; when the top code reader in the identification mechanism does not read the side information code, and the side code reader reads the shaft end information code, the wheel pair is not disassembled (the side information code is blocked by the bearing, and the side information code cannot be read by the top code reader).
Furthermore, the identification mechanism in the third scheme is a journal measurer, and the bearing measuring head can identify whether the bearing is installed on the wheel shaft or not by measuring the diameter of the wheel shaft (the wheel shaft with the bearing is larger in diameter due to the installation of the bearing, and the wheel shaft without the bearing is smaller in diameter).
Further, the journal measuring device in the third aspect is specifically a photoelectric sensor, and the photoelectric sensor can determine the diameter of the wheel set at the wheel axle by determining the time for blocking the photoelectric sensor when the wheel set passes by (since the moving speeds of the wheel set are consistent, the longer the time for blocking the photoelectric sensor by the wheel axle when the wheel set passes by is, the larger the diameter at the wheel axle is).
Further, in order to detect whether the wheel set has entered the identification area of the bearing, the identification area in the present solution is provided with a position sensor. When the wheel pair enters the identification area, the wheel pair passes through the position sensor and is sensed by the position sensor, and whether the wheel pair enters the identification area is judged.
Whether the wheel set enters the identification area or not is detected in an auxiliary mode, and then the wheel set corresponds to the identification result of the identification mechanism, so that the judgment is more accurate. For example, if both the position sensor and the identification mechanism identify a wheel pair, then the identification result is reliable; if only one of the position sensor and the identification mechanism senses the wheel pair, at least one of the position sensor and the identification mechanism is in failure, and the identification result may have errors.
Further, because the wheel pair may enter the identification area from two sides of the identification area, the position sensors in the scheme are respectively arranged on two sides of the identification area, and the adaptability is stronger.
Further, the identification area in this scheme specifically is the holding tank, and the holding tank sets up with the moving direction parallel of wheel pair. When the wheel pair moves, the wheel pair enters the accommodating groove and is identified by the identification mechanism arranged on the inner side of the accommodating groove.
Further, whether the bearings are installed at the two ends of the wheel pair or not is detected simultaneously, so that at least two recognition mechanisms are arranged in the scheme, and the recognition mechanisms are symmetrically arranged on the two sides respectively.
The beneficial effects of the utility model reside in that: when the wheel pair enters the identification area, the identification mechanism in the identification area can distinguish whether the bearing is installed on the wheel pair, so that the wheel pair provided with the bearing and the bearing not provided with the wheel pair can be distinguished to different processing stations during subsequent processing, and the maintenance requirements of different wheel pairs are met.

Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments more apparent, the present invention is further described in detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Example 1
As shown substantially in figures 1 to 3, a wheel set bearing identification device comprises an identification mechanism 1 and a mounting member 2. The mounting member 2 is provided with an identification region 3, and the identification mechanism 1 is mounted in the identification region 3.
The mounting part 2 and the identification means 1 in this embodiment are both intended to be mounted on the track side of a wheel set. When the wheelset moves in the track, the wheel axle of the wheelset then passes the identification area 3. The recognition mechanism 1 in the recognition area 3 can judge whether the bearing is installed on the wheel shaft, and the wheel set with the bearing and the wheel set without the bearing can enter different tracks and then move to different stations.
The identification area 3 in this embodiment is embodied as a receiving groove, through which the wheel axle passes when the wheel pair is moved. The diameter of holding tank is great simultaneously, and then the wheel pair of not co-altitude of adaptation.
The identification means 1 in this embodiment is embodied as a code reader 11. The code reader 11 is also embodied as a recognition camera. The identification camera is arranged on the side face of the accommodating groove and is opposite to the shaft end of the wheel shaft. Thus, when the wheel set passes the identification area 3, the information code on the axle end is read by the code reader 11. And at the same time, the code reader 11 is directly connected with a remote control center. The remote control center can then recognize whether the wheelset is bearing-mounted (the bearing-mounted wheelset and the non-bearing-mounted wheelset have been code-scanned before entering the service shop and the information codes are stored in the system).
The position sensors 4 are provided on both sides of the identification area 3 in the present embodiment. The position sensor 4 may be embodied as a proximity switch, which detects the wheel set when its axle passes the proximity switch, and the identification means 1 is activated to identify the axle.
The position sensors 4 in the present embodiment are respectively arranged on both sides, so that the wheel sets can be detected by the position sensors 4 from both sides reaching the identification area 3.
The identification area 3 in this embodiment is specifically a receiving groove, and the wheel axle of the wheel pair can pass through the receiving groove and is identified by the identification mechanism 1 located inside the receiving groove.
The identification means 1 in this embodiment is provided in two, and symmetrically provided on both sides, respectively. When the wheel set passes by, both ends of the wheel set can recognize whether the bearing is detached.
Example 2:
the present embodiment is different from embodiment 1 in that it is specifically shown in fig. 4. The identification means 1 in this embodiment is a code reading means 12. The identification appliance 1 comprises in particular a top code reader 121 and a side code reader 122. The top code reader 121 is disposed at the top of the receiving groove, and the side code reader 122 is disposed at the side of the receiving groove. When the wheel pair passes through the receiving groove, the top code reader 121 can read the side information code of the side of the wheel shaft. And the side code reader 122 can read the axle end information code of the wheel pair.
Since the wheel axle side information code of the wheel pair on which the bearing is mounted is blocked by the bearing, the top code reader 121 cannot read the information code on the side of the wheel axle. Therefore, if the wheel set enters the identification area 3, the code reading mechanism 12 can read the side information code and the shaft end information code of the wheel shaft at the same time, and the wheel shaft is disassembled. If the wheel set enters the identification area 3, the code reading mechanism 12 only reads the axle end information code of the axle, and the axle is provided with the bearing.
Example 3
The present embodiment is different from embodiment 1 in that it is specifically shown in fig. 5. The identification means 1 in this embodiment is a journal measurer 13, and the journal identification means 1 can measure the diameter of the axle. When the diameter of the wheel axle is larger than the standard value, the wheel axle is provided with a bearing; if the diameter of the wheel axle is in accordance with the standard value, the wheel axle is not provided with a bearing.
The bearing measurer can be specifically a photoelectric sensor, and the photoelectric sensor detects the time of passing through the photoelectric sensor by the pair of wheels, so that the diameter of the wheel axle is measured.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
