Description

Technical Field

[0001] The utility model relates to the technical field of beam cranes, and more specifically to a track self-cleaning beam crane. Background Art

[0002] Beam crane is a type of crane, which is composed of a bridge and a lifting trolley. The bridge moves longitudinally along the ground track and moves horizontally along the bridge. It has three working mechanisms: lifting, bridge travel, and trolley travel. It is driven by manpower or electricity. It is mostly used to transport goods in factories or workshops. It is used to lift goods in factories, warehouses, material yards and other places. It is forbidden to use it in flammable, explosive and corrosive media environments.

[0003] However, in the prior art, most of the rails of beam cranes need to be cleaned manually regularly. If the rails are not cleaned for a long time, the efficiency of the beam crane's displacement will be affected, and the debris on the rails will rub against the pulleys and cause wear, resulting in unnecessary cost waste in the later stage.

[0004] In addition, due to the large size of the beam crane, if it is cleaned regularly by manual labor, each cleaning will require a lot of manpower and take a long time, which will affect the energy of the personnel and affect work efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a self-cleaning rail beam crane, which aims to effectively solve the problem that most beam crane rails in the prior art need to be cleaned manually on a regular basis. If the rails are not cleaned for a long time, the efficiency of the beam crane along the displacement will be affected, and the debris on the rails will cause wear and tear due to friction with the pulley, resulting in unnecessary cost waste in the later stage.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions:

[0007] A rail self-cleaning beam crane, comprising a beam crane body and two rail bodies, wherein pulley seats are fixedly connected below the vertical beams on both sides of the beam crane body, and a plurality of sliding wheels are rotatably connected to the inner side of the pulley seats at equal intervals, wherein the pulley seats are all clamped on the upper side of the corresponding rail bodies, and the sliding wheels are all in contact with the surface of the rail bodies;

[0008] A spray device is provided on the outer wall of the pulley seat on the side away from each other, one end of the pulley seat is fixedly connected with an extension plate, a scraper is provided under the extension plate, connecting rods are fixedly connected on both sides above the scraper, and the connecting rods are slidably connected to the extension plate. The device has a simple and compact structure, and realizes the self-cleaning effect of flushing, shoveling and brushing the track through the self-movement of the beam crane, saving the time and energy consumed by manual cleaning and improving efficiency.

[0009] As a preferred solution of the utility model, the spray device includes a water tank fixedly connected to the pulley seat, a water injection pipe is fixedly connected to one side of the water tank, a booster pump is fixedly installed at one end of the water tank, the output end of the booster pump is fixedly connected to the spray pipe, and the other end of the spray pipe is arranged close to the surface of the track body.

[0010] As a preferred solution of the utility model, a protective box is fixedly connected to the upper middle portion of the extension plate, and a transmission mechanism is provided between the protective box and the scraper.

[0011] As a preferred solution of the utility model, the transmission mechanism includes a servo motor fixedly installed on one side of the protection box, and the output end of the servo motor extends into the interior of the protection box and is fixedly connected to the first gear.

[0012] As a preferred solution of the utility model, a threaded sleeve is rotatably connected between the protection box and the extension plate, one end of the threaded sleeve extends into the interior of the protection box and is fixedly connected with a second gear, and the second gear is meshingly connected with the first gear.

[0013] As a preferred solution of the utility model, the other end of the threaded sleeve is threadedly connected to a screw rod, and the other end of the screw rod is rotatably connected to the middle part of the scraper.

[0014] As a preferred solution of the utility model, an extension shaft is rotatably connected to the inner side of the pulley seat and one end close to the scraper, and a water absorption sleeve is fixedly provided on the outer wall of the extension shaft.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) Clean water is added to the water tank through the water injection pipe, and the clean water in the water tank is sprayed out from the spray pipe through the booster pump. Since the end of the spray pipe is close to the surface of the track body, the clean water passes through the end of the spray pipe to wash away the floating dust and debris on the surface of the track body, thereby achieving preliminary cleaning of the surface of the track body. In addition, as the main body of the beam crane moves, the track body can be gradually flushed to ensure the self-cleaning efficiency of the entire track body.

[0017] (2) In order to further improve the self-cleaning efficiency of the track body, while the spray device is spraying, the servo motor drives the first gear to rotate, and while the first gear rotates, it drives the meshing second gear to rotate, and while the second gear rotates, it drives the coaxial threaded sleeve to rotate. Since the threaded sleeve is threadedly connected to the screw, and the scraper is limited by the connecting rod and the extension plate, the threaded sleeve can rotate to continuously adjust the scraper position downward and fit the surface of the track body. As the beam crane body moves, the stubborn stains on the surface of the track body are removed, thereby further improving the self-cleaning efficiency of the track body.

[0018] (3) The absorbent sleeve can be a cylindrical sleeve made of absorbent cloth or sponge, which is sleeved on the outer wall of the extension shaft, and the absorbent sleeve fits the surface of the track body. As the beam crane body moves, it absorbs the residual cleaning water to avoid leaving water stains as much as possible. BRIEF DESCRIPTION OF THE DRAWINGS

Pulley seats 101 are fixedly connected under the vertical beams on both sides of the beam crane body 1. A plurality of sliding wheels 102 are rotatably connected to the inner side of the pulley seats 101 at equal intervals. The pulley seats 101 are all clamped on the top of the corresponding rail bodies 2, and the sliding wheels 102 are all in contact with the surface of the rail bodies 2.

[0031] In a further embodiment, the beam crane body 1 can be limited between two track bodies 2 by the pulley seat 101, and the beam crane body 1 can move forward and backward along the track body 2 by the sliding wheel 102 while lifting and moving objects.

[0032] For details, please refer to Figure 1 and Figure 2 A spray device 3 is provided on the outer wall of the pulley seat 101 on the side away from each other, and the spray device 3 includes a water tank 301 fixedly connected to the pulley seat 101, and a water injection pipe 302 is fixedly connected to one side of the water tank 301. A booster pump 303 is fixedly installed at one end of the water tank 301, and a spray pipe 304 is fixedly connected to the output end of the booster pump 303, and the other end of the spray pipe 304 is arranged close to the surface of the track body 2.

[0033] In a further embodiment, clean water is added to the interior of the water tank 301 through the water injection pipe 302, and the clean water inside the water tank 301 is sprayed out from the spray pipe 304 through the booster pump 303. Since the port of the spray pipe 304 is close to the surface of the track body 2, the clean water passes through the port of the spray pipe 304 to wash away the floating dust and debris on the surface of the track body 2, thereby achieving preliminary cleaning of the surface of the track body 2, and as the beam crane body 1 moves, the track body 2 can be gradually flushed to ensure the self-cleaning efficiency of the entire track body 2.

[0034] For details, please refer to Figure 2 , Figure 3 and Figure 4One end of the pulley seat 101 is fixedly connected to an extension plate 103, a scraper 4 is arranged below the extension plate 103, connecting rods 5 are fixedly connected to both sides above the scraper 4, the connecting rods 5 are slidably connected to the extension plate 103, a protective box 6 is fixedly connected to the middle part of the upper part of the extension plate 103, a transmission mechanism is arranged between the protective box 6 and the scraper 4, the transmission mechanism includes a servo motor 7 fixedly installed on one side of the protective box 6, the output end of the servo motor 7 extends to the interior of the protective box 6 and is fixedly connected to the first gear 8, a threaded sleeve 10 is rotatably connected between the protective box 6 and the extension plate 103, one end of the threaded sleeve 10 extends to the interior of the protective box 6 and is fixedly connected to the second gear 9, the second gear 9 is meshed with the first gear 8, the other end of the threaded sleeve 10 is threadedly connected to a screw 11, and the other end of the screw 11 is rotatably connected to the middle part of the scraper 4.

[0035] In a further embodiment, in order to further improve the self-cleaning efficiency of the track body 2, while the spray device 3 sprays, the servo motor 7 drives the first gear 8 to rotate, and while the first gear 8 rotates, it drives the meshing second gear 9 to rotate, and while the second gear 9 rotates, it drives the coaxial threaded sleeve 10 to rotate. Since the threaded sleeve 10 is threadedly connected to the screw rod 11, and the scraper 4 is limited by the connecting rod 5 and the extension plate 103, the threaded sleeve 10 rotates to continuously adjust the position of the scraper 4 downward and fit the surface of the track body 2. With the displacement of the beam crane body 1, the stubborn stains on the surface of the track body 2 are removed, thereby further improving the self-cleaning efficiency of the track body 2;

[0036] In addition, the protective box 6 can protect the first gear 8 and the second gear 9, and try to avoid the first gear 8 and the second gear 9 being directly exposed to the outside and damaged, which would cause unnecessary cost waste.

[0037] For details, please refer to Figure 3 The inner side of the pulley seat 101 and one end close to the scraper 4 are rotatably connected with an extension shaft 12, and the outer wall of the extension shaft 12 is fixedly provided with a water absorption sleeve 13.

[0038] In a further embodiment, the water-absorbing sleeve 13 can be a cylindrical sleeve made of absorbent cloth or sponge, which is sleeved on the outer wall of the extension shaft 12, and the water-absorbing sleeve 13 fits the surface of the track body 2. As the beam crane body 1 moves, the residual cleaning water is absorbed to avoid leaving water stains as much as possible.

[0039] Working principle:

[0040] When the utility model is used, the main body 1 of the beam crane can move forward and backward along the main body 2 of the track through the sliding wheel 102, and at the same time, lift and move the object. During the process, the booster pump 303 is activated, and the booster pump 303 sprays the cleaning water inside the water tank 301 from the spray pipe 304. Since the port of the spray pipe 304 is close to the surface of the main body 2 of the track, the clean water passes through the port of the spray pipe 304 to wash away the floating dust and debris on the surface of the main body 2 of the track, and the main body 2 of the track can be gradually washed with the displacement of the main body 1 of the beam crane. At the same time, the servo motor 7 is activated to drive the first gear 8 to rotate, and the first gear 8 rotates and drives the meshing second gear 9 to rotate. The second gear 9 rotates and drives the coaxial threaded sleeve 10 to rotate. Since the threaded sleeve 10 is threadedly connected to the screw 11, and the scraper 4 is limited by the connecting rod 5 and the extension plate 103, the threaded sleeve 10 rotates to make the scraper 4 position continuously lowered and fit the surface of the track body 2. With the displacement of the beam crane body 1, the stubborn stains on the surface of the track body 2 are removed, thereby further improving the self-cleaning efficiency of the track body 2. Finally, with the displacement of the beam crane body 1, the water absorption sleeve 13 absorbs the cleaning water remaining on the surface of the track body 2.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
