Description

Technical Field

[0001] This invention relates to the field of crane technology, and in particular to a dust removal device for overhead crane tracks. Background Technology

[0002] A bridge crane is a type of overhead crane that runs on elevated tracks. The bridge of the bridge crane runs longitudinally along tracks laid on both sides of the elevated structure, while the trolley runs laterally along tracks laid on the bridge, forming a rectangular working area. This allows for full utilization of the space beneath the bridge for lifting and transporting materials without obstruction from ground equipment.

[0003] Whether the surface of the overhead crane track is clean and free of foreign objects is the key to whether the overhead crane can start and run steadily. Currently, the track is generally cleaned by blowing off dust, but this method cannot remove large particles of obstruction. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal device for crane tracks to solve the problems existing in the prior art and to remove large particulate obstacles in the crane tracks.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] This invention provides a dust removal device for crane tracks, comprising:

[0007] The mobile vehicle body is movable within the overhead crane track and can move back and forth within the overhead crane track;

[0008] The dust blowing mechanism is located at both ends of the mobile vehicle body and is used to blow dust from the bottom of the overhead crane track. It can also push the dust from the bottom of the overhead crane track to both ends of the overhead crane track during the reciprocating movement of the mobile vehicle body.

[0009] The dust collection unit is fixedly installed on the outer wall at both ends of the overhead crane track, and the dust collection unit is equipped with an adjustable lifting seat.

[0010] The dust removal component is rotatably mounted on one side of the bottom of the lifting seat via a connector. The dust removal component has an arc structure, and its outer bottom can abut against the inner bottom of the crane track.

[0011] The first driving unit is used to drive the dust removal component to swing, thereby shoveling the dust accumulated at both ends of the crane track between the inner arc surface of the dust removal component and the inner wall of the crane track.

[0012] The agitating mechanism is movably disposed on the inner side of the dust removal component, and can agitate the dust between the inner arc surface of the dust removal component and the inner wall of the crane track into the dust collection part.

[0013] The second driving unit is used to drive the actuating mechanism to move along the inner arc surface of the dust removal component.

[0014] As the mobile vehicle moves back and forth within the overhead crane track, the dust-blowing mechanism pushes large dust particles from the bottom of the track to both ends, preventing obstacles within the track from affecting the movement of the mobile vehicle. During the downward flipping of the dust-cleaning component, large dust particles accumulated at both ends of the track are shoveled between the inner arc surface of the dust-cleaning component and the inner wall of the track. Then, the lifting seat is moved upward, causing the bottom of the dust-cleaning component to move to the top of the track. At this point, the second drive unit drives the agitator to swing inside the dust-cleaning component, moving the large dust particles located on the inner arc surface of the component into the dust collection unit. This facilitates the removal and collection of dust within the track. Furthermore, this invention can be installed on existing overhead crane tracks without requiring modifications, reducing operating costs.

[0015] Optionally, the soot blowing mechanism includes soot blowing housings slidably mounted on both ends of the mobile vehicle body. A soot blowing nozzle is provided on the side of the soot blowing housing away from the mobile vehicle body, and an air pump is connected to the soot blowing nozzle through an extended air pipe.

[0016] Optionally, the side wall of the mobile vehicle body is provided with a horizontally arranged guide groove, and the outer wall of the soot blowing shell is equipped with a connecting side wing. A guide component is fixedly provided on the side of the connecting side wing near the mobile vehicle body. The guide component is inserted into the guide groove, and the outer diameter of the guide component is adapted to the inner diameter of the guide groove. The guide component can move left and right in the guide groove.

[0017] Optionally, a fixed seat is installed on the outer wall of the mobile vehicle body, and a movable side wing is installed on one side of the fixed seat via a spring. The bottom of the movable side wing is fixedly connected to the outer wall of the top of the soot blowing shell. A jacking cam is movably installed on the outer wall of the mobile vehicle body. The jacking cam is located on the side of the movable side wing away from the spring, and one end of the jacking cam can abut against the side of the movable side wing. The camshaft of the jacking cam is driven by a cam motor.

[0018] Optionally, the dust collection unit includes a dust collection housing with a top opening, and the dust collection housing is connected to the outer walls at both ends of the overhead crane track via a connecting seat; the lifting seat is installed on the top of the side wall of the dust collection housing.

[0019] Optionally, the bottom of the lifting seat is connected to the dust collection unit via a telescopic component. The connecting component includes a first mounting seat and a first mounting rod. The first mounting seats are installed on both sides of the bottom of the lifting seat, and the first mounting rods are movably installed on opposite sides of the two first mounting seats. One end of the two first mounting rods is fixedly connected to the dust removal component. The first driving unit can drive the first mounting rods to swing.

[0020] Optionally, the actuating mechanism includes a second mounting seat installed on the sides of the two first mounting rods. A rotating rod is movably mounted on one side of the two second mounting seats opposite to each other. A second mounting rod is mounted on one side of the rotating rod. A movable component is mounted on the end of the second mounting rod away from the rotating rod. The movable component is located on the side of the dust removal component near the rotating rod, and the outer arc surface of the movable component abuts against the inner arc surface of the dust removal component. The second driving part can drive the rotating rod to rotate.

[0021] Optionally, a pushing component is installed at one end of the movable component near the dust collection housing, and the pushing component is arranged perpendicular to the inner arc surface of the movable component.

[0022] Optionally, the pushing component has a hollow structure, and an air outlet is provided on the side of the pushing component near the dust collection housing. An air pump is connected to the inside of the pushing component through an extension tube.

[0023] Optionally, the width of the dust removal component is adapted to the inner diameter of the crane track, and the width of the movable component is the same as the width of the dust removal component.

[0024] The present invention achieves the following technical effects compared to the prior art:

[0025] This invention allows the mobile vehicle to reciprocate within a crane track. The dust-blowing shell pushes dust in the direction of the mobile vehicle's movement, moving larger dust particles from the bottom of the crane track to both ends, thus preventing obstacles within the track from affecting the vehicle's movement. The lifting seat can be raised and lowered via a telescopic component, and the first mounting rod can be rotated via a first drive unit. When the dust-cleaning component flips downwards, its outer arc surface becomes tangent to the inner wall of the bottom of the crane track. The first drive unit then rotates the first mounting rod until the end of the dust-cleaning component furthest from the first mounting rod abuts against the inner wall of one end of the crane track. During the downward flipping process, large dust particles accumulated at both ends of the overhead crane track can be shoveled between the inner arc surface of the dust removal component and the inner wall of the overhead crane track. Then, the lifting seat is driven upward by the telescopic component, so that the bottom of the dust removal component moves to the top of the overhead crane track. At this time, the rotating rod is driven to rotate by the second drive unit, causing the moving component to swing inside the dust removal component, which moves the large dust particles located on the inner arc surface of the dust removal component into the dust collection housing, making it easier to remove and collect dust in the overhead crane track. Moreover, this dust removal device can be installed on the existing overhead crane track without modifying the overhead crane track, reducing the cost of use. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The purpose of this invention is to provide a dust removal device for crane tracks to solve the problems existing in the prior art and to remove large particulate obstacles in the crane tracks.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] This invention provides a dust removal device for crane tracks, in one specific embodiment, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a movable car body 2 movably installed inside the overhead crane track 1. Both ends of the movable car body 2 are equipped with dust-blowing mechanisms 3 for blowing dust from the bottom of the overhead crane track 1. Each dust-blowing mechanism 3 includes a dust-blowing housing 32 slidably mounted at both ends of the movable car body 2, used to push large dust particles from the bottom of the overhead crane track 1 to both ends of the track during the reciprocating movement of the movable car body 2. Dust collection housings 11 are installed on the outer walls of both ends of the overhead crane track 1 via connecting seats 12. A telescopic component 10 is installed on the top of the dust collection housing 11. A lifting seat 8 is installed at one end of the piston rod of the telescopic component 10. First mounting seats 9 are installed on both sides of the bottom of the lifting seats 8. First mounting rods 5 are movably installed on opposite sides of the two first mounting seats 9. The same dust-cleaning component is installed at one end of each of the two first mounting rods 5. 4. The dust removal component 4 has an arc-shaped structure; the first mounting rod 5 is driven by the first driving part 6 to swing; the dust removal component 4 is provided with a tossing mechanism 7, which is used to toss the dust into the dust collection housing 11 when the dust at both ends of the crane track 1 is lifted to the top of the crane track 1; the tossing mechanism 7 includes a second mounting seat 71 installed on the sides of the two first mounting rods 5, the same rotating rod 75 is movably installed on the opposite side of the two second mounting seats 71, a second mounting rod 73 is installed on one side of the rotating rod 75, and a movable part 72 is installed on the end of the second mounting rod 73 away from the rotating rod 75; it also includes a second driving part 74 for driving the rotating rod 75 to rotate; the movable part 72 is located on the side of the dust removal component 4 near the rotating rod 75, and the outer arc surface of the movable part 72 abuts against the inner arc surface of the dust removal component 4.

[0036] When the mobile vehicle 2 reciprocates within the overhead crane track 1, the dust blowing shell 32 pushes the dust in the direction of travel of the mobile vehicle 2, pushing large dust particles at the bottom of the overhead crane track 1 to both ends of the track 1. This prevents obstacles within the track 1 from affecting the movement of the mobile vehicle 2. The lifting seat 8 can be raised and lowered by the telescopic component 10, and the first mounting rod 5 can be rotated by the first drive unit 6. This causes the outer arc surface of the dust cleaning component 4 to be tangent to the bottom inner wall of the overhead crane track 1 when it flips downwards. The first drive unit 6 then drives the first mounting rod 5 to rotate until the end of the dust cleaning component 4 away from the first mounting rod 5 abuts against the inner wall of one end of the overhead crane track 1. During the downward flipping process, large dust particles accumulated at both ends of the overhead crane track 1 can be shoveled between the inner arc surface of the dust removal component 4 and the inner wall of the overhead crane track 1. Then, the lifting seat 8 is driven upward by the telescopic component 10, so that the bottom of the dust removal component 4 moves to the top of the overhead crane track 1. At this time, the rotating rod 75 is driven to rotate by the second drive unit 74, which causes the movable component 72 to swing inside the dust removal component 4, and the large dust particles located on the inner arc surface of the dust removal component 4 are moved into the dust collection housing 11, which facilitates the removal and collection of dust in the overhead crane track 1. Moreover, this dust removal device can be installed on the existing overhead crane track 1 without modifying the overhead crane track 1, which reduces the cost of use.

[0037] In a preferred embodiment of the present invention, a pushing component 77 is installed at one end of the movable component 72 near the dust collection housing 11, and the pushing component 77 and the inner arc surface of the movable component 72 are arranged perpendicular to each other.

[0038] In a preferred embodiment of the present invention, the pushing component 77 has a hollow structure, and an air outlet 76 is provided on the side of the pushing component 77 near the dust collection housing 11. The air outlet of the air pump 31 is connected to the interior of the pushing component 77 through an extension tube. When the dust on the inner arc surface of the dust removal component 4 is moved by the movable component 72 and the pushing component 77, the air pump 31 blows air into the pushing component 77, and the airflow is ejected from the air outlet 76 to blow away the dust, thereby preventing the dust from adhering to the side of the pushing component 77 and ensuring effective dust collection.

[0039] In a preferred embodiment of the present invention, a blowing nozzle 33 is provided on the side of the blowing housing 32 away from the moving vehicle body 2. The interior of the blowing housing 32 is connected to the air outlet of the air pump 31 through an extended air pipe 34. During the horizontal movement of the moving vehicle body 2, the air pump 31 injects air into the blowing housing 32, and the airflow is sprayed out from the blowing nozzle 33 to blow away small dust particles on the inner wall of the bottom of the crane track 1.

[0040] In a preferred embodiment of the present invention, the side wall of the mobile vehicle body 2 is provided with a guide groove 13, and the outer wall of the soot blowing shell 32 is equipped with a connecting side wing 17. A guide component 14 is provided on the side of the connecting side wing 17 near the mobile vehicle body 2, and the outer diameter of the guide component 14 is adapted to the inner diameter of the guide groove 13. A fixed seat 18 is installed on the outer wall of the mobile vehicle body 2, and a movable side wing 16 is installed on one side of the fixed seat 18 by a spring. The bottom of the movable side wing 16 is connected to the outer wall of the soot blowing shell 32. A top-moving cam 15 is movably installed on the outer wall of the mobile vehicle body 2, and the position of the top-moving cam 15 corresponds to the position of the side of the movable side wing 16. The camshaft of the top-moving cam 15 is driven by a cam motor. During the movement of the mobile vehicle body 2, the cam motor can drive the top-moving cam 15 to rotate, thereby reciprocatingly striking the side of the movable side wing 16, so that the movable side wing 16 is on the top-moving cam 15. The soot blowing housing 32 moves back and forth under the action of the impact and the elasticity of the spring, so that during the horizontal movement of the moving car body 2, it can move back and forth perpendicular to the moving car body 2, thereby changing the relative position of the soot blowing nozzle 33 and the bottom inner wall of the overhead crane track 1. This ensures that the gas sprayed from the soot blowing nozzle 33 can blow soot more thoroughly onto the bottom inner wall of the overhead crane track 1. In addition, the guide groove 13 and the guide component 14 guide and limit the reciprocating movement of the soot blowing housing 32, preventing the two ends of the soot blowing housing 32 from colliding with the inner wall of the overhead crane track 1.

[0041] In a preferred embodiment of the present invention, the width of the dust removal component 4 is adapted to the inner diameter of the crane track 1, and the width of the movable component 72 is consistent with the width of the dust removal component 4.

[0042] When the mobile vehicle 2 reciprocates within the overhead crane track 1, the dust blowing shell 32 pushes the dust in the direction of the mobile vehicle 2's movement, pushing large dust particles at the bottom of the overhead crane track 1 to both ends of the track 1. This prevents obstacles within the track 1 from affecting the movement of the mobile vehicle 2. The lifting seat 8 can be raised and lowered via the telescopic component 10, and the first mounting rod 5 can be rotated via the first drive unit 6. This causes the outer arc surface of the dust cleaning component 4 to be tangent to the bottom inner wall of the overhead crane track 1 when it flips downwards. The first drive unit 6 then drives the first mounting rod 5 to rotate until the end of the dust cleaning component 4 away from the first mounting rod 5 is tangent to the inner wall of one end of the overhead crane track 1. In the process of the dust removal component 4 flipping downwards, large dust particles accumulated at both ends of the overhead crane track 1 are shoveled between the inner arc surface of the dust removal component 4 and the inner wall of the overhead crane track 1. Then, the lifting seat 8 is driven upwards by the telescopic component 10, so that the bottom of the dust removal component 4 moves to the top of the overhead crane track 1. At this time, the rotating rod 75 is driven to rotate by the second drive unit 74, which causes the movable component 72 to swing inside the dust removal component 4, pushing the large dust particles located on the inner arc surface of the dust removal component 4 into the dust collection housing 11. This facilitates the removal and collection of dust inside the overhead crane track 1, and the dust removal device can be installed on the existing overhead crane track 1. No modification to the overhead crane track 1 is required, reducing operating costs. When the moving part 72 and the pushing part 77 are used to move the dust on the inner arc surface of the dust removal part 4, the air pump 31 blows air into the pushing part 77, and the airflow is ejected from the air outlet 76 to blow away the dust, preventing dust from adhering to the side of the pushing part 77 and ensuring effective dust collection. During the horizontal movement of the moving car body 2, the air pump 31 injects air into the dust blowing housing 32, and the airflow is ejected from the dust blowing nozzle 33 to blow away small particles of dust on the bottom inner wall of the overhead crane track 1. During the movement of the moving car body 2, the cam motor can drive the top convex... The wheel 15 rotates, which in turn strikes the side of the movable side wing 16 repeatedly. Under the striking action of the jacking cam 15 and the elastic action of the spring, the movable side wing 16 moves back and forth. As the soot blowing shell 32 moves horizontally with the moving car body 2, it can move back and forth relative to the moving car body 2. This changes the relative position of the soot blowing nozzle 33 and the bottom inner wall of the overhead crane track 1, ensuring that the gas sprayed by the soot blowing nozzle 33 can blow soot more comprehensively onto the bottom inner wall of the overhead crane track 1. The guide groove 13 and the guide component 14 guide and limit the reciprocating movement of the soot blowing shell 32, preventing the two ends of the soot blowing shell 32 from colliding with the inner wall of the overhead crane track 1.
