Description

Technical Field

[0001] This application relates to the technical field of excavator manufacturing, and particularly to an excavator track assembly device. Background Art

[0002] With the development of construction machinery, excavators have become one of the most important construction machinery in engineering construction. An excavator is a machine that uses a bucket to excavate materials such as soil, coal, and sediment, and load them into transport vehicles. During the assembly of an excavator, track assembly is one of the important assembly links, and it is necessary to install track shoes on the track chain.

[0003] In related technologies, when assembling track shoes, after workers insert hexagon head screws into the screw holes on the track chain, they usually use related assembly devices (such as manual hexagon socket wrenches, electric hexagon socket wrenches) to tighten each hexagon head screw one by one to complete the assembly of the track shoes. Since there are many track shoes to be assembled, and each track shoe needs to be fixed with four hexagon head screws, this not only increases the labor intensity of workers, but also reduces the assembly efficiency of the excavator. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems in related technologies to some extent.

[0005] To this end, an object of this application is to provide an excavator track assembly device. By tightening multiple hexagon head screws simultaneously, it can not only reduce the labor intensity of workers, but also effectively improve the assembly efficiency of the excavator.

Detailed implementation manners

[0026] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0027] The excavator track assembly device of the embodiments of the present application will be described below with reference to the drawings.

[0028] As Figures 1 - 5 shown, the excavator track assembly device of the embodiments of the present application may include a support frame 10, a support assembly 20, a telescopic mechanism 30, a first assembly component 40, a second assembly component 50, a first driving component 60, and a second driving component 70.

[0029] Among them, the support assembly 20 is disposed on the support frame 10 in a liftable manner. One end of the telescopic mechanism 30 is connected to the support frame 10, and the other end of the telescopic mechanism 30 is connected to the support assembly 20. Among them, the telescopic mechanism 30 is used to drive the support assembly 20 to perform lifting movement.

[0030] It should be noted that the telescopic mechanism 30 described in this embodiment may be a cylinder. The cylinder block of the cylinder can be connected to the support frame 10 through threaded fasteners (screws, bolts or bolts), and the output end of the cylinder is connected to the support assembly 20.

[0031] The first assembly component 40 is detachably arranged on the support assembly 20, the second assembly component 50 is movably arranged on the support assembly 20, and the second assembly component 50 is arranged opposite to the first assembly component 40.

[0032] The first driving component 60 is arranged on the support assembly 20, and the first driving component 60 is connected to the second assembly component 50. Among them, as Figures 1 - 3 shown, the first driving component 60 is used to drive the second assembly component 50 to move longitudinally, so as to adjust the longitudinal distance between the first assembly component 40 and the second assembly component 50 to adapt to the distance between two large-spacing threaded holes that are close to each other on the crawler chain.

[0033] It should be noted that one track shoe is installed on one link of the crawler chain, and two pairs of threaded holes for installing the track shoe are provided on one link. The two pairs of threaded holes include a pair of large-spacing threaded holes and a pair of small-spacing threaded holes (that is, the large-spacing threaded holes refer to the large distance between the pair of threaded holes, and the small-spacing threaded holes refer to the small distance between the pair of threaded holes). Therefore, the large-spacing threaded holes on one link are parallel to the large-spacing threaded holes on another link, and the small-spacing threaded holes on one link are also parallel to the small-spacing threaded holes on another link.

[0034] Among them, the first assembly component 40 and the second assembly component 50 may respectively include a support plate 41, a sliding plate 42, a first assembly mechanism 43, a second assembly mechanism 44, a driving mechanism 45 and a first belt transmission mechanism 46.

[0035] Among them, the support plate 41 is arranged on the support assembly 20, the sliding plate 42 is slidably arranged on the support plate 41, the first assembly mechanism 43 is rotatably arranged on the support plate 41, the second assembly mechanism 44 is rotatably arranged on the sliding plate 42, and the second assembly mechanism 44 is arranged opposite to the first assembly mechanism 43.

[0036] It should be noted that the support plate in the first assembly component 40 described in this embodiment is fixedly arranged on the support assembly 20, while the support plate in the second assembly component 50 is movably arranged on the support assembly 20.

[0037] One end of the driving mechanism 45 is connected to the support plate 41, and the other end of the driving mechanism 45 is respectively connected to the first assembly mechanism 43 and the second assembly mechanism 44 through the first belt transmission mechanism 46. Among them, the driving mechanism 45 is used to drive the first belt transmission mechanism 46 to drive the first assembly mechanism 43 and the second assembly mechanism 44 to rotate for assembling the track to be assembled.

[0038] It should be noted that the driving mechanism described in this embodiment can be a motor. The body of the motor can be connected to the support plate 41 through threaded fasteners, and the output end of the motor is respectively connected to the first assembly mechanism 43 and the second assembly mechanism 44 through the first belt transmission mechanism 46.

[0039] The second driving component 70 is arranged on the support component 20, and the second driving component 70 is connected to the sliding plate 42. Among them, as Figures 1 - 3 described, the second driving component 70 is used to drive the sliding plate 42 to drive the second assembly mechanism 44 to move horizontally to adjust the horizontal distance between the first assembly mechanism 43 and the second assembly mechanism 44 to adapt to the distance between each pair of threaded holes on each link.

[0040] Specifically, when assembling the track to be assembled, relevant workers first need to place the track chain flat on the workbench, fix it in a straight line, place each track plate on the corresponding link, and make the through holes on the track plate correspond to the threaded holes on the link. Then, insert each hexagon head screw into the corresponding through hole and threaded hole in sequence.

[0041] Then, the worker sets the excavator track assembly device at the position of the track to be assembled (this position can be the workbench in the factory building for assembling the track). Then, the worker uses the first driving component 60 to drive the second assembly component 50 to move longitudinally to adjust the longitudinal distance between the first assembly component 40 and the second assembly component 50, and further adjust the longitudinal distance between the first assembly mechanism 43 and the second assembly mechanism 44 in the first assembly component 40 and the first assembly mechanism 43 and the second assembly mechanism 44 in the second assembly component 50 to adapt to the distance between two relatively close large-spacing threaded holes on the track chain.

[0042] Then, the worker controls the second driving component 70 to drive the sliding plate 42 to drive the second assembly mechanism 44 to move horizontally to adjust the horizontal distance between the first assembly mechanism 43 and the second assembly mechanism 44 to adapt to the distance between each pair of threaded holes on each link. Thus, it can be applicable to the assembly of track plates of different sizes and has the advantage of a wide application range.

[0043] After the two first assembly mechanisms 43 and the two second assembly mechanisms 44 respectively correspond to the large-spacing threaded holes on two adjacent links, the staff controls the first drive assembly 60 and the second drive assembly 70 to stop working, and controls the output end of the cylinder (retractable mechanism 30) to extend. The cylinder drives the first assembly mechanism 43 and the second assembly mechanism 44 to descend synchronously through the support assembly 20 and sleeved on the hex heads of the corresponding hexagon head screws.

[0044] Then, the staff controls the motor (drive mechanism 45) to start. The started motor drives the first assembly mechanism 43 and the second assembly mechanism 44 to rotate through the first belt drive mechanism 46. The rotating first assembly mechanism 43 and second assembly mechanism 44 respectively drive the corresponding hexagon head screws to rotate. At the same time, the cylinder drives the first assembly mechanism 43 and the second assembly mechanism 44 to continue to descend through the support assembly 20 until the hexagon head screws are tightened on the crawler chain and the crawler plate is fixed. Then the motor stops working, and at the same time, the output end of the cylinder retracts, and drives the first assembly mechanism 43 and the second assembly mechanism 44 to disengage from the tightened hexagon head screws through the support assembly 20. Repeat this process to tighten the hexagon head screws arranged in the large-spacing threaded holes on the crawler chain in turn.

[0045] Finally, the staff adjusts the horizontal and vertical distances between the first assembly mechanism 43 and the second assembly mechanism 44 to be opposite to the small-spacing threaded holes, and then controls the first assembly mechanism 43 and the second assembly mechanism 44 to tighten the hexagon head screws located in the small-spacing threaded holes, thereby fixing the crawler plate on the crawler chain. Furthermore, by using multiple first assembly mechanisms 43 and second assembly mechanisms 44 to tighten multiple hexagon head screws simultaneously, it can not only reduce the labor intensity of workers, but also effectively improve the assembly efficiency of the crawler plates of the excavator.

[0046] In an embodiment of the present application, as Figure 2 shown, the support assembly 20 may include a support table 21 and a plurality of support columns 22.

[0047] Among them, the support table 21 is arranged below the support frame 10, and the support table 21 is connected to the other end of the retractable mechanism 30, that is, the top wall of the support table 21 is connected to the output end of the cylinder (retractable mechanism 30).

[0048] A plurality of support columns 22 are vertically distributed on the support table 21, and the tops of the plurality of support columns 22 respectively penetrate through the support frame 10 and extend above the support frame 10.

[0049] It can be understood that by arranging a plurality of support columns 22 on the support table 21, a limiting effect is achieved to prevent the support table 21 from shaking when moving up and down.

[0050] In an embodiment of the present application, asFigures 1 - 3 As shown, the first driving assembly 60 may include a first lead screw 61, a first slider 62, and a first driving member 63.

[0051] Wherein, a first slideway 201 is provided on the support platform 21, and the first lead screw 61 is rotatably arranged in the first slideway 201.

[0052] The first slider 62 is slidably arranged in the first slideway 201, and the first slider 62 is sleeved on the first lead screw 61 and is threadedly connected to the first lead screw 61. The first slider 62 is connected to the support plate 41 in the second assembly component 50.

[0053] One end of the first driving member 63 is connected to the support platform 21, and the other end of the first driving member 63 is connected to one end of the first lead screw 61.

[0054] It should be noted that the first driving member 63 described in this embodiment may be a first bidirectional stepper motor, and the output shaft of the first bidirectional stepper motor is connected to one end of the first lead screw 61.

[0055] Specifically, when it is necessary to adjust the distance between the second equipment assembly 50 and the first assembly component 40, the relevant staff can drive the first lead screw 61 to rotate by controlling the first bidirectional stepper motor (the first driving member 63). The rotating first lead screw 61 drives the second assembly component 50 to move towards or away from the first assembly component 40 through the first slider 62, thereby realizing the adjustment of the longitudinal distance between the second equipment assembly 50 and the first assembly component 40.

[0056] In an embodiment of the present application, as Figure 3 and Figure 4 shown, the first assembly mechanism 43 and the second assembly mechanism 44 may respectively include a support shaft 410 and an assembly component 420.

[0057] Wherein, the support shaft 410 is rotatably arranged on the support plate 41 or the slide plate 42, that is, the support shaft in the first assembly mechanism 43 is rotatably arranged on the support plate 41, and the support shaft in the second assembly mechanism 44 is rotatably arranged on the slide plate 42. The support shaft 410 is connected to the first belt transmission mechanism 46, and the assembly component 420 is detachably arranged on the support shaft 410. It can be understood that the assembly component 420 described in this embodiment is detachably arranged on the support shaft 410, which is convenient for the installation and replacement of the assembly component 420. For example, the assembly component 420 can be connected to the support shaft by means of snap connection, riveting, or connection with threaded fasteners, etc.

[0058] For the sake of clearly explaining the previous embodiment, in an embodiment of the present application, as Figures 3 - 5As shown, the first belt drive mechanism 46 may include two first driving pulleys 461, two first driven pulleys 462, two first tensioning pulleys 463 and two first belts 464.

[0059] Among them, the two first driving pulleys 461 are symmetrically and rotatably arranged on the support plate 41, and one of the first driving pulleys 461 is connected to the other end of the driving mechanism 45, that is, one of the first driving pulleys 461 is arranged on the output shaft of the motor (driving mechanism 45).

[0060] The two first driven pulleys 462 are respectively sleeved on the corresponding support shafts 410, and the two first driven pulleys 462 are arranged in parallel.

[0061] The two first tensioning pulleys 463 are symmetrically and rotatably arranged on the sliding plate 42, and the two first tensioning pulleys 463 are arranged close to the first driven pulley 462 arranged on the sliding plate 42.

[0062] The two first belts 464 are respectively sleeved on the corresponding first driving pulleys 461, first driven pulleys 462 or first tensioning pulleys 463. That is, one of the first belts is sleeved on the two first driving pulleys 461, one of the driven pulleys and the two first tensioning pulleys, while the other first belt is sleeved on one of the first driving pulleys and one of the driven pulleys.

[0063] Specifically, when it is necessary to control the rotation of the assembly parts 420 in the first assembly mechanism 43 and the second assembly mechanism 44, the staff can drive one of the first driving pulleys 461 to rotate by controlling the motor (driving mechanism 45). The rotating first driving pulley 461 drives the two first driven pulleys 461 to rotate respectively through the two first belts 464. The two rotating first driven pulleys drive the corresponding assembly parts 420 to rotate through the support shafts 410, so as to realize tightening the hexagon head screws on the crawler chain.

[0064] In an embodiment of the present application, as Figures 1 - 5 shown, the second driving assembly 70 may include a vertical plate 71, a second slider 72, two second lead screws 73, a second driving component 74 and a second belt drive mechanism 75.

[0065] Among them, the vertical plate 71 is detachably arranged on the support table 21, and a second slideway 701 is provided on the vertical plate 71. It can be understood that the vertical plate 71 described in this embodiment is detachably arranged on the support table 21, which is convenient for the installation and replacement of the vertical plate 71. For example, the vertical plate 71 can be arranged on the support table 21 through threaded fasteners.

[0066] The second slider 72 is slidably arranged in the second slideway 701. Two second lead screws 73 are respectively rotatably arranged on the corresponding vertical plates 71 and the second slider 72, and the two second lead screws 73 are arranged in parallel. The top ends of the second lead screws 73 penetrate through the support plate 41 and are threadedly connected to the slide plate 42, that is, the slide plate 42 is sleeved on the second lead screws 73.

[0067] One end of the second driving component 74 is connected to the vertical plate 71, and the other end of the second driving component 74 is respectively connected to the two second lead screws 73 through the second belt transmission mechanism 75.

[0068] It should be noted that, in this embodiment, the second driving component 74 described may be a second bidirectional stepper motor. The body of the second bidirectional stepper motor can be connected to the vertical plate 71 through threaded fasteners, and the output end of the second bidirectional motor is connected to the second belt transmission mechanism 75.

[0069] For the sake of clearly explaining the previous embodiment, in an embodiment of the present application, as Figure 4 shown, the second belt transmission mechanism 75 may include a second driving pulley 751, two second driven pulleys 752, two second tension pulleys 753 and a second belt 754.

[0070] Among them, the second driving pulley 751 is rotatably arranged on the vertical plate 71. The two second driven pulleys 752 are respectively sleeved on the corresponding second lead screws 73, and one of the second driven pulleys 752 is connected to the other end of the second driving component 74, that is, one of the second driven pulleys 752 is arranged on the output shaft of the second bidirectional stepper motor (the second driving component 74).

[0071] The two second tension pulleys 753 are symmetrically and rotatably arranged on the second slider 72. The second belt 754 is sequentially sleeved on the second driving pulley 751, the two second driven pulleys 752 and the two second tension pulleys 753.

[0072] Specifically, as Figures 1 - 3 shown, when it is necessary to adjust the lateral distance between the assembly components 420 in the first assembly mechanism 43 and the second assembly mechanism 44, the staff can control the second bidirectional stepper motor to drive one of the second driven pulleys 752 to rotate. The rotating second driven pulley 752 drives the other second driven pulley 752 to rotate through the second belt 754. The two rotating second driven pulleys drive the corresponding second lead screws 73 to rotate. The rotating second lead screws 73 drive the corresponding slide plate 42 to drive the corresponding second assembly mechanism 44 to move laterally towards or away from the first equipment mechanism 43, so as to realize the adjustment of the lateral distance between the assembly components 420 in the first assembly mechanism 43 and the second assembly mechanism 44. Furthermore, it can be applicable to the assembly of track shoes of different sizes and has the advantage of a wide application range.

[0073] In one embodiment of the present application, as Figure 6 shown, the assembly component 420 may include a sleeve 421, a plurality of clamping columns 422, a magnet column 423, and a plurality of springs 424.

[0074] Among them, the sleeve 421 is detachably arranged on the support shaft 410, and a plurality of sliding grooves 4211 are formed at the bottom of the inner cavity of the sleeve 421. For example, the plurality of sliding grooves 4211 may be 20, 21, 22, 23, 24 sliding grooves 4211, etc. The specific number of openings can be set according to the actual situation and is not limited herein, and the plurality of sliding grooves 4211 are arranged in layers and surround each other.

[0075] It should be noted that the cross-section of the inner cavity of the sleeve 421 described in this embodiment may be circular, hexagonal, octagonal, etc. The specific shape is not limited, and the inner diameter of the sleeve 421 is much larger than the size of the hexagonal head of the hexagonal head screw, so as to adapt to hexagonal head screws of different sizes.

[0076] The plurality of clamping columns 422 and the magnet column 423 are respectively slidably arranged in the corresponding sliding grooves 4211, and the plurality of clamping columns 422 are arranged around the magnet column 423.

[0077] One end of each of the plurality of springs 424 is fixedly connected to the bottom wall of the corresponding sliding groove 4211, and the other end of each of the plurality of springs 424 is fixedly connected to the ends of the corresponding clamping column 422 and the magnet column 423.

[0078] Specifically, when it is necessary to screw the hexagonal head screw into the threaded hole on the crawler chain, the worker controls the output end of the cylinder (the telescopic mechanism 30) to extend and drives the assembly component 420 to move downward through the support table 21. As the assembly component 421 gradually moves downward, some of the clamping columns 422 and the magnet column 423 located in the sleeve 421 are pushed into the sliding grooves 4211 in the sleeve 421 by the hexagonal head screw, and the remaining clamping columns 422 surround and limit the hexagonal head of the hexagonal head screw. At the same time, the magnet column 423 adsorbs and fixes the hexagonal head.

[0079] Then the worker can control the motor (the driving mechanism 45) to start. The started motor drives the sleeve 421 in the assembly component 420 to rotate through the first belt transmission mechanism 46. The rotating sleeve 421 drives the hexagonal head screw to rotate through the plurality of clamping columns 422 and the magnet column 423, and then drives the hexagonal head screw to rotate to assemble the crawler plate onto the crawler chain.

[0080] After the hexagonal head screw is screwed into the threaded hole on the crawler chain, the worker can control the output end of the cylinder to retract, and then drive the assembly component 420 to rise through the support table 21, so that the plurality of clamping columns 422 and the magnet column 423 in the sleeve 421 are separated from the hexagonal head screw.

[0081] In one embodiment of the present application, as Figure 4 and Figure 5 shown, the above-mentioned excavator track assembly device may further include two sets of rollers 80, and the two sets of rollers 80 are symmetrically and rotatably arranged on the bottom wall of the support frame 10. It should be noted that the two sets of rollers described in this embodiment may be universal wheels with a self-locking function.

[0082] It can be understood that by arranging the rollers 80 on the bottom wall of the support frame 10, it is convenient for the staff to drive the excavator track assembly device to move, so as to assemble the remaining track plates to be assembled.

[0083] In summary, the excavator track assembly device of the embodiment of the present application can not only reduce the labor intensity of workers by tightening multiple hexagon head screws at the same time, but also effectively improve the assembly efficiency of the excavator. In addition, it can also be applicable to the assembly of track plates of different sizes and has the advantage of a wide application range.
