Description

Technical Field

[0001] The present invention relates to the technical field of OHT overhead cranes, in particular to a trolley for cleaning tracks of OHT overhead cranes. Background Art

[0002] In semiconductor factories, the tracks of OHT overhead cranes are easily covered with dust. Frequent acceleration and deceleration of the trolleys causes wheel wear and generates dust, which affects the normal operation of the overhead cranes, affects the positioning accuracy of the trolleys, and pollutes the environment. Therefore, the dust on the OHT overhead crane tracks needs to be cleaned at regular intervals.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Example:

[0031] As attached Figure 1 To the attached Figure 9 As shown:

[0032] A trolley for cleaning an OHT overhead crane track comprises a shell 1 and an overhead crane track 2. The overhead crane track 2 is located directly above the shell 1. A mounting plate 3 is fixedly connected to the upper surface of the shell 1. A driving mechanism 4 is fixedly installed on the upper surface of the mounting plate 3. The output end of the driving mechanism 4 is slidably connected to the overhead crane track 2. A cleaning mechanism 5 is fixedly installed on the upper surface of the mounting plate 3. The cleaning mechanism 5 comprises a dust removal nozzle 501 and a first cleaning mechanism 502. The dust removal nozzle 501 is located directly above the overhead crane track 2. The first cleaning mechanism 502 is in contact with the upper surface of the overhead crane track 2. A dust suction and collection device 7 is fixedly installed inside the shell 1. The input end of the dust suction and collection device 7 is fixedly connected to a dust extraction pipeline 8. The other end of the dust extraction pipeline 8 is fixedly connected to the output end of the dust removal nozzle 501. A through hole 6 is provided on the outer wall of the shell 1.

[0033] It is worth mentioning that the dust suction and dust collection device 7 includes a shell, a negative pressure fan, and a dust bag. The dust bag and the negative pressure fan are both installed inside the shell. The dust bag is located at the input end of the negative pressure fan. When the negative pressure fan is started, the negative pressure fan generates negative pressure, and the dust is sucked into the dust bag through the dust removal nozzle 501 and the dust extraction pipe 8 for collection.

[0034] The driving mechanism 4 is a conventional driving mechanism on an existing OHT overhead crane. When dust on the overhead crane track 2 needs to be cleaned, the driving mechanism 4 drives the cleaning mechanism 5, the mounting plate 3 and the housing 1 to move in the direction of the overhead crane track 2.

[0035] There are two first cleaning mechanisms 502 , and the two first cleaning mechanisms 502 are respectively located on both sides of the dust removal nozzle 501 .

[0036] The first cleaning mechanism 502 includes a connecting plate 5021, which is fixedly connected to the outer wall of the dust removal nozzle 501. The bottom of the connecting plate 5021 is fixedly connected to a mounting shell 5022. A fixed cavity 5023 is provided on the lower surface of the mounting shell 5022. The mounting shell 5022 is fixedly connected to the fixed cavity 5023 with a brush 5024. The brush 5024 is in contact with the upper surface of the overhead crane track 2.

[0037] It is worth mentioning that the brush 5024 can also be replaced with a cleaning cloth.

[0038] The overhead crane track 2 includes an outer track 201, and the inner side of the outer track 201 is fixedly connected to the inner track 202. The dust removal nozzle 501 includes an outer nozzle 5011, and the outer nozzle 5011 is located directly above the outer track 201. An inner nozzle 5012 is provided directly above the inner track 202. A pipeline interface 5013 is fixedly connected above the inner nozzle 5012. The inner nozzle 5012, the outer nozzle 5011, and the pipeline interface 5013 are interconnected. The other end of the pipeline interface 5013 is fixedly connected to the input end of the dust extraction pipeline 8.

[0039] In the above technical solution, when the driving mechanism 4 drives the cleaning mechanism 5 to move on the overhead crane track 2, the dust suction and dust collection device 7 is started at the same time, and the dust suction and dust collection device 7 generates negative pressure. The dust is sucked into the dust suction and dust collection device 7 through the dust removal nozzle 501 and collected. The outer suction nozzle 5011 absorbs the dust on the upper surface of the outer track 201, and the inner suction nozzle 5012 absorbs the dust on the upper surface of the inner track 202.

[0040] The cleaning mechanism 5 also includes a movable adjustment mechanism 503 and a second cleaning mechanism 504. The second cleaning mechanism 504 is fixedly installed at the output end of the movable adjustment mechanism 503. The second cleaning mechanism 504 contacts the upper surface of the inner track 202. The second cleaning mechanism 504 has the same structure as the first cleaning mechanism 502.

[0041] The movable adjustment mechanism 503 includes a guide shaft 5031, which is fixedly mounted on the upper surface of the mounting plate 3. The outer wall of the guide shaft 5031 is slidably sleeved with a positioning plate 5032. The outer wall of the positioning plate 5032 is rotatably connected to a rotating screw 5036. The bottom end of the rotating screw 5036 is fixedly connected to a rotating shaft 5038. The rotating shaft 5038 is slidably connected to the mounting plate 3. The bottom end of the rotating shaft 5038 is fixedly connected to a mounting seat 50310. The second cleaning mechanism 504 is fixedly mounted on the outer wall of the mounting seat 50310. The outer wall of the rotating shaft 5038 is sleeved with a compression spring 50311. The compression spring 50311 is located below the mounting plate 3. The outer wall of the rotating shaft 5038 is slidably sleeved with a linear bearing 5039. The linear bearing 5039 is fixedly sleeved with the mounting plate 3. The compression spring 50311 is located below the linear bearing 5039.

[0042] In the above technical solution, the driving mechanism 4 drives the mounting plate 3, the movable adjustment mechanism 503, and the second cleaning mechanism 504 to move in the direction of the overhead travelling vehicle track 2. The second cleaning mechanism 504 can clean the dust on the upper surface of the inner track 202. The compression spring 50311 enables the second cleaning mechanism 504 to be elastically pressed on the upper surface of the inner track 202, with radial pre-pressure to ensure the cleaning effect.

[0043] The top of the guide shaft 5031 is threadedly connected to a limit screw 50312 .

[0044] In the above technical solution, when the positioning plate 5032 moves vertically, the limiting screw 50312 provides a limit for the positioning plate 5032.

[0045] An installation cavity 5033 is provided on the lower surface of the positioning plate 5032, and a return spring 5034 is placed inside the installation cavity 5033. The positioning plate 5032 is located in the installation cavity 5033 and is fixedly connected to a fixed block 5035. There are two return springs 5034, and the two return springs 5034 are respectively located on both sides of the fixed block 5035. The outer wall of the rotating screw 5036 is fixedly connected to a return base 5037. The upper surface of the return base 5037 extends to the interior of the installation cavity 5033. One end of the two return springs 5034 is respectively fixedly connected to the two sides of the return base 5037, and the other end of the two return springs 5034 is respectively fixedly connected to the two sides of the fixed block 5035.

[0046] In the above technical solution, when the second cleaning mechanism 504 encounters an obstacle when cleaning the upper surface of the inner track 202, the obstacle squeezes the second cleaning mechanism 504, and the second cleaning mechanism 504 drives the rotating shaft 5038 to rotate through the mounting seat 50310, and the rotating shaft 5038 drives the reset base 5037 to rotate by rotating the screw 5036, so that the second cleaning mechanism 504 avoids the obstacle. After avoiding the obstacle, the reset base 5037 is pushed to move by the reset spring 5034, and the reset base 5037 drives the second cleaning mechanism 504 to rotate and reset by rotating the screw 5036, the rotating shaft 5038, and the mounting seat 50310.

[0047] The specific usage and function of this embodiment are as follows:

[0048] When the present invention is used, when it is necessary to clean the dust on the overhead crane track 2, the driving mechanism 4 drives the cleaning mechanism 5, the mounting plate 3 and the housing 1 to move in the direction of the overhead crane track 2;

[0049] A dust removal nozzle 501 and a first cleaning mechanism 502 are mounted on the mounting plate 3. When the driving mechanism 4 drives the cleaning mechanism 5 to move on the overhead crane track 2, the first cleaning mechanism 502 can clean the dust on the upper surface of the overhead crane track 2. At the same time, the dust collection device 7 is activated, and the dust collection device 7 generates negative pressure, and the dust is sucked into the dust collection device 7 through the dust removal nozzle 501 and collected.

[0050] Please refer to the above structure and process Figure 1-5 .

[0051] At the same time, the driving mechanism 4 drives the mounting plate 3, the movable adjustment mechanism 503, and the second cleaning mechanism 504 to move in the direction of the overhead travelling vehicle track 2. The second cleaning mechanism 504 can clean the dust on the upper surface of the inner track 202. The compression spring 50311 enables the second cleaning mechanism 504 to elastically press on the upper surface of the inner track 202, with radial pre-pressure to ensure the cleaning effect.

[0052] Please refer to the above structure and process Figure 6-9 .

[0053] At the same time, when the second cleaning mechanism 504 encounters an obstacle when cleaning the upper surface of the inner track 202, the obstacle squeezes the second cleaning mechanism 504, and the second cleaning mechanism 504 drives the rotating shaft 5038 to rotate through the mounting seat 50310, and the rotating shaft 5038 drives the reset base 5037 to rotate by rotating the screw 5036, so that the second cleaning mechanism 504 avoids the obstacle. After avoiding the obstacle, the reset base 5037 is pushed to move by the reset spring 5034, and the reset base 5037 drives the second cleaning mechanism 504 to rotate and reset by rotating the screw 5036, the rotating shaft 5038, and the mounting seat 50310.
