Description

Technical Field

[0001] The present application relates to the technical field of lifting equipment, and in particular to a gantry crane track cleaning device. Background Art

[0002] Gantry cranes are bridge-type cranes whose bridge is supported on ground tracks by legs on both sides. They are characterized by high efficiency and strong cargo adaptability, and are widely used in port unloading operations. Currently, the tracks on gantry cranes are mostly directly exposed to the air, making it easy for foreign matter to stick to the top surface of the tracks. This is especially true in the operating environment of port gantry cranes, which are subject to heavy dust pollution. When too much foreign matter accumulates, it will hinder the sliding of the moving structure on the gantry crane and increase the load on the driving structure of the gantry crane. Therefore, the gantry crane tracks need to be cleaned regularly to ensure that there are no foreign matter stains on them, thereby ensuring the normal operation of the gantry crane. When cleaning, the existing gantry crane track cleaning device simply uses a brush to sweep away the dust on the track, and the cleaning effect is not good enough. Utility Model Content

[0003] The utility model aims to solve the problem that the existing door crane track cleaning device has poor cleaning effect, thereby providing a door crane track cleaning device with good cleaning effect.

[0004] The utility model solves the above problems by adopting the following technical solutions:

[0005] A gantry track cleaning device includes a traveling trolley, which is rolled on the gantry track. A support frame is fixed to one end of the traveling trolley, and an upper scraper and two side scrapers are elastically connected to the support frame. The elastic displacement directions of the upper scraper and the two side scrapers are parallel and perpendicular to the length direction of the gantry track. The bottom end of the upper scraper is used to abut the top of the gantry track, and the inner ends of the two side scrapers are used to abut the two sides of the gantry track.

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following beneficial effects:

[0007] The utility model replaces the brush cleaning in the prior art with scraper cleaning, wherein the foreign matter on the top of the door machine track is scraped off by the upper scraper, and the foreign matter on both sides of the door machine track is scraped off by the two side scrapers, and the upper scraper and the side scrapers are elastically connected to the walking trolley so that the bottom of the upper scraper abuts against the top of the door machine track, thereby achieving a better cleaning effect. Moreover, if there are hard stones or foreign matter on the ground on both sides of the door machine track, the side scrapers can automatically avoid them to avoid damage.

[0008] As a preferred embodiment, a further technical solution of the present invention is:

[0009] The upper scraper and the two side scrapers are movably sleeved with limit frames, the outer ends of which are fixed to the traveling trolley. The inner side walls of the limit frames are provided with guide grooves, the length direction of which is the same as the elastic displacement direction of the upper scraper. Limit blocks are fixed to the side walls of the upper scraper. When the upper scraper undergoes elastic displacement, the limit blocks move in the guide grooves. The guide grooves define the elastic displacement direction of the upper scraper, thereby ensuring the stability of the upper scraper during elastic displacement.

[0010] The support frame includes an upper support plate and two lower support plates. A first spring is fixedly connected between the upper support plate and the upper scraper. When the first spring is in a compressed state, the bottom end of the upper scraper abuts the top of the door crane track. Second springs are respectively connected between the two lower support plates and the two side scrapers. When the second springs are in a relaxed state, the bottom surfaces of the two side scrapers are flush with the bottom surface of the door crane track. The first and second springs drive the upper and side scrapers to undergo elastic displacement.

[0011] A screw is inserted into the first spring. The lower end of the screw is fixed to the top of the upper scraper, and the upper part of the screw is movably mounted on the upper support plate. A nut is threadedly connected to the screw above the upper support plate. The length of the screw located in the middle of the first spring is adjusted by the nut to compensate for the loss at the bottom end of the upper scraper.

[0012] Guide rods are provided on both sides of the second spring, the top of the guide rods being fixed to the lower support plate, the bottom of the guide rods being movably inserted into the top of the side scraper, and the bottom of the guide rods being fixed with anti-slip blocks. The guide rods increase the stability of the side scraper when the second spring is deformed.

[0013] The front and rear sides of the bottom of the side scraper are arranged in an arc shape. With the above structure, when the bottom end of the side scraper contacts a hard stone or foreign object, the arc-shaped contact surface can provide a certain buffer, reducing the risk of the side scraper being bent.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0021] Reference Figure 1-5 The embodiment of the present application discloses a gantry crane track cleaning device, which is applied to the bottom track of a gantry crane, including a walking trolley 1, which is rollingly set on the gantry crane track 2, and the walking trolley 1 includes walking wheels and a walking frame, and the walking wheels are rotatably set at the bottom of the walking frame, and the walking wheels drive the walking frame to walk on the gantry crane track 2; a support frame is fixed to the front end of the walking frame, and an upper scraper 9 and two side scrapers 8 are elastically connected to the support frame, and the elastic displacement directions of the upper scraper 9 and the two side scrapers 8 are parallel, and the elastic displacement directions of the upper scraper 9 and the two side scrapers 8 are perpendicular to the length direction of the gantry crane track 2, and the bottom end of the upper scraper 9 is used to abut the top of the gantry crane track 2, and the inner ends of the two side scrapers 8 are used to abut the two sides of the gantry crane track 2.

[0022] In this embodiment, the support frame includes an upper support plate 3 and two lower support plates 5. The top of the upper scraper 9 is fixedly sleeved with a first sleeve 91, and the tops of the two side scrapers 8 are fixedly sleeved with a second sleeve 63. Two first springs 4 are fixedly connected between the top surface of the first sleeve 91 and the upper support plate 3. When the first spring 4 is in a compressed state, the bottom end of the upper scraper 9 abuts against the top of the door machine track 2; second springs 6 are respectively connected between the top surfaces of the two second sleeves 63 and the two lower support plates 5. When the second spring 6 is in a natural state, the inner ends of the two side scrapers 8 are in contact with the door machine track 2, and the bottom surfaces of the two side scrapers 8 are flush with the bottom surface of the door machine track 2.

[0023] In this embodiment, a limit frame 7 is movably sleeved on the upper scraper 9 and the two side scrapers 8. The rear side wall of the limit frame 7 is fixed to the front end of the traveling trolley 1. Guide grooves 71 are provided on the front inner wall and the rear inner wall of the limit frame 7. The length direction of each guide groove 71 is the same as the elastic displacement direction of the upper scraper 9. Limit blocks 92 are fixed on the front side wall and the rear side wall of the upper scraper 9. When the upper scraper 9 undergoes elastic displacement, the limit blocks 92 move in the guide grooves 71. The elastic displacement direction of the upper scraper 9 is limited by the guide grooves 71, thereby ensuring the stability of the upper scraper 9 during elastic displacement.

[0024] Preferably, two first limiting sleeves 31 are fixed to the bottom surface of the upper support plate 3 and the top surface of the first sleeve 91, respectively. The top and bottom ends of the first spring 4 are respectively inserted into the first limiting sleeves 31 on the upper and lower sides, and are respectively fixed to the bottom surface of the upper support plate 3 and the top surface of the first sleeve 91 in the middle of the first limiting sleeve 31. A screw 41 is inserted in the middle of the first spring 4, and the lower end of the screw 41 is fixed to the top surface of the first sleeve 91. A through hole is opened on the upper support plate 3, and the aperture of the through hole is larger than the diameter of the screw 41, so that the upper part of the screw 41 is movably inserted in the through hole. A nut is threadedly connected to the screw 41 above the upper support plate 3, and the length of the screw 41 located in the middle of the first spring 4 is adjusted by the nut, thereby compensating for the loss of the bottom end of the upper scraper 9; the bottom surface of the lower support plate 5 and the second sleeve 63 The top surfaces are respectively fixed with second limit sleeves 62, and the top and bottom ends of the second spring 6 are respectively inserted in the second limit sleeves 62 on the upper and lower sides, and are respectively fixed to the bottom surface of the lower support plate 5 and the top surface of the second sleeve 63 in the middle of the second limit sleeve 62; a guide rod 61 is provided on both sides of each second spring 6, the top end of the guide rod 61 is fixed to the lower support plate 5, and the lower part of the guide rod 61 is movably inserted in the top of the second sleeve 63, and the bottom end of the guide rod 61 is fixed with an anti-slip block 64 to prevent the second sleeve 63 from escaping from the guidance of the guide rod 61 when it is displaced by the second spring 6; the displacement direction of the first spring 4 is guided by the first limit sleeve 31, and the displacement direction of the second spring 6 is guided by the second limit sleeve 62 and the guide rod 61, so that the upper scraper 9 and the side scraper 8 are more stable when displaced.

[0025] Preferably, the front and rear sides of the bottom of the side scraper 8 are configured to be arc-shaped. With this structure, when the bottom end of the side scraper 8 comes into contact with a hard stone or foreign object, the stone or foreign object exerts an oblique squeezing force on the arc-shaped contact surface, causing the side scraper 8 to move upward, thereby squeezing the second spring 6, driving the side scraper 8 to avoid the stone or foreign object, thereby reducing the risk of the side scraper 8 being damaged.

[0026] The utility model changes the brush cleaning in the prior art into scraper cleaning, and the upper scraper 9 and the side scraper 8 are set to be elastically connected to the walking trolley 1 through a spring. During installation, the first spring 4 is compressed and fixed on the upper support plate 3, and the nut is slightly loosened to make the bottom end of the upper scraper 9 abut against the top surface of the door machine track 2. When the walking trolley 1 moves, the upper scraper 9 is driven to scrape off foreign matter on the top surface of the door machine track 2, and the two side scrapers 8 are driven to scrape off foreign matter on both sides of the door machine track 2. During the cleaning process, the first spring 4 is always in a compressed state. When the bottom of the upper scraper 9 is worn, the upper scraper 9 The bottom end does not abut against the top surface of the door machine track 1. At this time, the nut is rotated upward, and the preload of the first spring 4 gradually decreases, causing the first spring 4 to gradually stretch, thereby driving the upper scraper 9 to move downward until the bottom end of the upper scraper 9 abuts against the top surface of the door machine track 1 again. Stop rotating the nut to compensate for the bottom wear of the upper scraper 9; since the door machine track 2 is fixed to the ground, and if there are hard stones or foreign objects on the ground on both sides of the door machine track 2, the side scraper 8 can automatically squeeze the second spring 6 to drive the side scraper 8 to move upward to avoid damage to the side scraper 8.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. Any equivalent changes made using the contents of the present invention specification and its drawings are included in the scope of the present invention.
