Description

Technical Field

[0001] This utility model relates to the field of pulley inspection equipment technology, and in particular to an inspection device for track pulleys. Background Technology

[0002] See appendix Figure 1 The image shows a pulley for use with a track. The pulley has a wheel frame and a roller. The wheel frame includes a support plate and a connecting plate. The support plate is used to install the roller. The connecting plate has a U-shaped connection port and a connection hole at the joint between the support plate and the connecting plate.

[0003] After the pulley is manufactured, it needs to be installed on the track, and then a load is applied to the wheel frame to make it slide back and forth on the track to simulate the pulley in actual use and thus test the quality of the entire pulley.

[0004] Currently, when inspecting pulleys for quality, workers install the pulleys onto the track, then hang a load on the pulley frame, and then manually pull the loaded pulley back and forth on the track. However, there are the following problems with manual inspection: 1. Because a load is hung on the pulley frame, it requires a lot of physical strength to pull it manually. After a whole day of manual inspection, the workers' arms will feel sore. Therefore, this inspection method is very labor-intensive for the workers.

[0005] 2. When manually pulling the pulley, it is impossible to guarantee that the sliding stroke on the track will be consistent each time. After the staff has been inspecting for a period of time, their arms will become sore, and the sliding stroke of the pulley will be greatly shortened. This will result in a large deviation from the set inspection stroke, which will lead to a decline in inspection quality.

[0006] Therefore, there is an urgent need for an inspection device for track pulleys to replace manual inspection, so as to reduce the labor intensity of workers during inspection and ensure the quality of inspection. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides an inspection device for track pulleys, which solves the problems of high labor intensity for workers and inability to guarantee inspection quality when pulleys are inspected manually.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] An inspection device for a track pulley includes a support frame, a track beam horizontally provided at the top of the support frame for cooperating with the pulley, a drive motor provided at one end of the support frame, a synchronous belt provided at the output end of the drive motor, a connector clamped on the synchronous belt, the connector being detachably connected to the pulley frame, and a counterweight frame provided at the bottom of the connector, with multiple counterweight blocks placed inside the counterweight frame.

[0010] Furthermore, the connector has a wedge block at one end near the wheel frame. The wedge block can be accommodated in the U-shaped connection port of the connecting plate. A pin hole is opened through the wedge block, and a pin is provided in the pin hole.

[0011] Furthermore, the wedge block is provided with a threaded hole at the connection hole position of the wheel frame, and a connecting bolt is provided in the threaded hole, so that the wedge block and the wheel frame are connected by the connecting bolt.

[0012] Furthermore, the track beam is provided with slide rails at both ends, the slide rails are fixed on the support frame, the support frame is provided with a push drive cylinder, and the output end of the push drive cylinder is connected to the track beam.

[0013] Furthermore, the support frame has a base plate at its inner bottom, a lifting drive cylinder at one end of the base plate, and a tray at the output end of the lifting drive cylinder.

[0014] Furthermore, the counterweight frame is vertically provided with an elastic element, one end of which is connected to a connector, and the other end is provided with a pressure plate.

[0015] Furthermore, the support frame is equipped with a counting unit for detecting the number of times the connector reciprocates on the track beam.

[0016] Furthermore, the counting unit includes a sensor switch and a display, the sensor switch being mounted on the opposite side of the connector, and the display being fixed on the support frame.

[0017] Furthermore, a reference plate is provided on one side of the connector, and the length of the reference plate is greater than the sliding displacement of the track beam on the support frame.

[0018] Furthermore, a magnetic block is provided on one side of the reference plate.

[0019] In summary, the beneficial technical effects of this utility model are as follows:

[0020] A connector was used to connect the wheel frame to the timing belt. By adding or removing counterweights on the counterweight frame, the sliding effect of the pulley under different loads during use was simulated. The timing belt was driven by a motor to make the entire pulley slide back and forth along the track beam instead of manually. This mechanical inspection method not only reduced the labor intensity of manual labor under load, but also ensured that the sliding position of the slide rail on the track beam was the same each time. This avoided the problem of shortening the sliding stroke after the manual labor force decreased, thus ensuring the quality of inspection. Attached Figure Description

[0029] The present invention will now be described clearly and completely with reference to the embodiments.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] See appendix Figure 1 As shown, a pulley for use with a track is provided. The pulley includes a wheel frame and rollers 3. The wheel frame is made of galvanized carbon steel. The wheel frame is formed by cold bending of sheet metal to obtain a support plate 1 and a connecting plate 2. The support plate 1 is connected to two sets of rollers 3. A U-shaped connection port 4 is provided on the connecting plate 2, and a connection hole 5 is provided at the joint between the support plate 1 and the connecting plate 2.

[0033] See appendix Figure 2-7 The image shows an inspection device for a track pulley, including a support frame 6, which is welded from rectangular tubing. Slide rails 8 are fixed to both ends of the top of the support frame 6. A track beam 7 is slidably mounted on the support frame 6 via the slide rails 8. During inspection, the pulley's roller 3 is placed in the track beam 7, which provides a sliding path for the entire pulley and supports its weight. A push-drive cylinder 9 is located in the middle of the track beam 7 on the support frame 6. The output end of the push-drive cylinder 9 is connected to the track beam 7. During use, the push-drive cylinder 9 controls the track beam 7 to slide horizontally along the slide rails 8.

[0034] A drive motor 10 is provided at one end of the support frame 6 located below the track beam 7. The output end of the drive motor 10 is provided with a synchronous belt 11 through a stepping pulley. The other end of the synchronous belt 11 is also connected to the support frame 6 through a stepping pulley.

[0035] A connector 12 is held on a timing belt 11. The top of the connector 12 is provided with a wedge 13 that can be accommodated in a U-shaped connection port 4. A pin hole is provided through the wedge 13, and a pin 14 is provided in the pin hole. The length direction of the pin 14 is perpendicular to the length direction of the U-shaped connection port 4. The wedge 13 is provided with a threaded hole at the concentric position of the connection hole 5. A connecting bolt 15 is provided in the threaded hole. When connecting the connector 12 to the wheel frame, the wedge 13 is first placed in the U-shaped connection port 4, and then the pin 14 is inserted into the pin hole to achieve the initial connection between the connector 12 and the wheel frame. Then, the connecting bolt 15 is connected to the threaded hole through the connection hole 5 to achieve the secondary connection between the connector 12 and the wheel frame. The connecting bolt 15 prevents the wedge 13 from falling out of the U-shaped connection port 4.

[0036] Furthermore, a counterweight frame 16 is provided at the bottom of the connector 12, and multiple counterweight blocks 17 are placed inside the counterweight frame 16. During the inspection, the counterweight blocks 17 simulate the load on the pulley during use. At the same time, an elastic element 18 is vertically provided inside the counterweight frame 16. One end of the elastic element 18 is connected to the connector 12, and the other end is provided with a pressure plate 19. The elastic element 18 provides elastic force to the pressure plate 19, and the pressure plate 19 further uses the elastic force to fix the counterweight blocks 17, thus improving the stability of the counterweight blocks 17 inside the counterweight frame 16.

[0037] Therefore, during inspection, connector 12 is connected to the wheel frame via wedge 13 and connecting bolt 15. Drive motor 10 uses synchronous belt 11 to drive the entire pulley to reciprocate linearly along track beam 7, thus replacing manual labor for pulley inspection. During the inspection process, drive motor 10 replaces manual labor in pulling the pulley, reducing the labor intensity of the staff. At the same time, the cooperation between drive motor 10 and synchronous belt 11 ensures that the pulley is slid to the same position on track beam 7 each time, thus fully guaranteeing the pulley's stroke during inspection and ensuring inspection quality.

[0038] Furthermore, the bottom of the support frame 6 is provided with a base plate, and the end of the base plate near the drive motor 10 is provided with a lifting drive cylinder 20. The output end of the lifting drive cylinder 20 is provided with a tray 21. When the connector 12 is connected to and disconnected from the wheel frame, the friction between the pin 14 and the wedge 13 will be greatly increased due to the gravity of the counterweight 17. If an upward lifting force is not applied to the entire connector 12 to eliminate the friction between the pin 14 and the wedge 13, the pin 14 cannot be pulled out of the pin hole. Therefore, after the inspection is completed, the connector 12 is brought to the top of the lifting drive cylinder 20 by the drive motor 10, and then the lifting drive cylinder 20 pushes the tray 21 upward. The tray 21 further applies an upward lifting force to the counterweight frame 16. At this time, the friction between the pin 14 and the wedge 13 is released, and the pin 14 can be easily pulled out of the pin hole. At the same time, when the connector 12 is connected to the wheel frame, it is not necessary to remove the counterweight 17 from the counterweight frame 16.

[0039] Furthermore, in order to improve the efficiency and quality of inspection, a counting unit is provided on the support frame 6. The counting unit includes an induction switch 22 installed on the opposite side of the connector 12 and a display 23 installed on the support frame 6. When the connector 12 slides back and forth along the track beam 7, the induction switch 22 will count once each time it passes through the induction switch 22 and display it on the display 23. When the number of reciprocations reaches the set value, the drive motor 10 stops and returns to the top of the lifting drive cylinder 20.

[0040] It should be noted that the induction switch 22 and display 23 used in this utility model are specifically infrared laser photoelectric automatic induction counters.

[0041] Furthermore, when the wheel frame is connected to the connector 12, the pulley is first placed in the track beam 7, and then the push drive cylinder 9 drives the track beam 7 to move forward along the slide rail 8. At this time, in order to make the U-shaped connection port 4 accurately fit into the wedge block 13, a reference plate 24 is provided on one side of the connector 12. The length of the reference plate 24 is greater than the sliding displacement of the track beam 7 on the support frame 6. After the pulley is placed in the track beam 7, one side of the wheel frame is pressed against the side wall of the reference plate 24. At this time, the U-shaped connection port 4 is located directly in front of the wedge block 13. Then, the push drive cylinder 9 drives the wheel frame to move forward along the reference plate 24 so that the U-shaped connection port 4 accurately fits into the wedge block 13.

[0042] Furthermore, in order to ensure that the wheel frame always moves in contact with the reference plate 24, a magnetic block 25 is provided on the other side of the reference plate 24. The magnetic block 25 attracts the wheel frame to ensure its direction of movement.

[0043] During inspection, the drive motor 10 first uses the synchronous belt 11 to place the connector 12 onto the tray 21 of the lifting cylinder. Then, a counterweight 17 of the same weight as the pulley in actual use is placed in the counterweight frame 16. At the same time, the drive cylinder 9 is pushed to control the track beam 7 away from the connector 12. Then, the operator places the pulley to be inspected into the track beam 7 and makes one end of the wheel frame abut against the side wall of the reference plate 24. Then, the drive cylinder 9 is pushed to drive the track beam 7 with the pulley to slide along the reference plate 24 toward the connector 12. The process continues until the U-shaped connector 4 is precisely engaged with the wedge block 13. Then, the pin 14 is inserted into the pin hole, and the wheel frame is connected to the wedge block 13 using the connecting bolt 15. Next, the lifting drive cylinder 20 retracts the tray 21. At this time, the weight of all the counterweights 17 is transferred to the pulley through the connector 12. Then, the drive motor 10 uses the synchronous belt 11 to make the pulley and connector 12 slide back and forth along the track beam 7. During the inspection process, the number of times the pulley slides is counted by the induction switch 22 to achieve the inspection purpose.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
