Description

Technical Field

[0001] The invention relates to the technical field of excavators, in particular to an automatically locked excavator bracket. Background Art

[0002] An excavator, also known as an excavator or a backhoe, uses a bucket to dig materials above or below the surface of the machine and load them into the transport excavator. From the development of construction machinery in recent years, the development of excavators has been relatively rapid. Excavators have become one of the most important construction machinery in engineering construction. However, in some specific scenarios, excavator supports are often used to increase the height of the excavator so that the excavator can work on different scenarios such as soil in train carriages.

[0003] For example, the utility model with application number CN201920024185.8 discloses an adjustable excavator support, which specifically relates to the field of excavator supports, including a support platform fixed to the bottom of the excavator. The utility model uses a hydraulic lifting platform in conjunction with an outer cylinder and an inner cylinder. When the excavator is not high enough or it is difficult to lift the bucket when digging, the internal controller of the excavator sends control information to the hydraulic lifting platform through the Bluetooth module to control the hydraulic lifting platform to work and lift the entire excavator, which plays an auxiliary lifting role; however, it is difficult for the excavator to automatically lock when it is on the support, resulting in the excavator position being offset when digging or loading materials.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatically locked excavator support is proposed. Summary of the invention

[0007] Furthermore, the first auxiliary frame and the second auxiliary frame have completely identical structures, and the length of the first auxiliary frame is smaller than the length of the support platform.

[0008] Furthermore, an outer surface of one side of the first auxiliary frame and the second auxiliary frame is provided with an adjustment component for auxiliary position adjustment, and two groups of the adjustment components are provided.

[0009] Furthermore, the adjustment assembly includes a fixed plate, a hydraulic cylinder and a side plate, and the outer surface of the fixed plate is provided with a hydraulic cylinder, and the output end of the hydraulic cylinder is installed with a side plate.

[0010] Furthermore, the side plate and the first auxiliary frame are in an integrated structure, and a guide component for assisting position movement is provided on the outer surface of the middle portion of the bottom of the first auxiliary frame.

[0018] 2. The automatically locked excavator support can move the first auxiliary frame through the design of the adjustment component and the guide component, and can make the connecting seat slide and move inside the slideway, so that the friction resistance can be reduced when the side plate and the first auxiliary frame connected to the side plate are driven to move by the design of the fixed plate and the hydraulic cylinder, which is more time-saving and labor-saving. By designing that the first auxiliary frame and the second auxiliary frame each correspond to a set of adjustment components and guide components, it is convenient to move the first auxiliary frame and the second auxiliary frame separately or move them to one side uniformly, and it is convenient to move the longitudinal position of the locked excavator, which is conducive to adjusting the position of the excavator on the support platform, and is convenient to increase the working range of the excavator.

[0019] 3. The automatically locked excavator support, through the design of two sets of independently controlled hydraulic lifting platforms inside the bottom frame, can make the support platform height drop and shift to one side at the same time, so that the support platform is in an inclined state, which is convenient for the excavator to drive to the protective layer on the outer surface of the receiving plate.

[0028] like Figure 1-Figure 6As shown, the present invention provides a technical solution: an automatically locked excavator support, including a support platform 1, a first auxiliary frame 2, a second auxiliary frame 3, a hydraulic lifting platform 4, a bottom frame 5, an adjustment component 6, a fixing plate 601, a hydraulic cylinder 602, a side plate 603, an auxiliary cylinder 7, a protective layer 8, a driving motor 9, a gear 10, a driving chain 11, a bottom plate 12, an auxiliary cover 13, a connecting column 14, an auxiliary component 15, a hydraulic rod 1501, an end plate 1502, a cleaning brush 1503, a built-in groove 16, a built-in column 17, a guide component 18, a connecting seat 1801, a side groove 1802, a pulley 1803, a slide 1804, a roller 19, a receiving plate 20 and an adjustment path 21, and the outer surface of the support platform 1 is provided with a first auxiliary frame 2 , and driving motors 9 are installed on both sides of the interior of the first auxiliary frame 2, a hydraulic lifting platform 4 is arranged at the bottom of the support platform 1, and a bottom frame 5 is installed at the bottom of the support platform 1, the bottom frame 5 forms a fixed structure with the hydraulic lifting platform 4 through screws, and the bottom frame 5 is a hollow rectangular structure with an open top. When the excavator is in use, the design of two sets of independently controlled hydraulic lifting platforms 4 inside the bottom frame 5 can make the support platform 1 drop in height and deviate to one side at the same time, so that the support platform 1 is in an inclined state, which is convenient for the excavator to travel to the protective layer 8 on the outer surface of the receiving plate 20. When the excavator travels to the outer surface of the protective layer 8, the receiving plate 20 is fixed to the first auxiliary frame 2 by bolts, which is conducive to the excavator to stably enter the outer surface of the protective layer 8, and the protective layer 8 is prevented from falling. The protective layer 8 is a crawler mat, which can protect the receiving plate 20 and reduce the damage of the excavator crawler to the receiving plate 20. In addition, the design of the hydraulic lifting platform 4 allows the support platform 1 to be lifted to a high height, which is convenient for the excavator to handle work at different heights. The first auxiliary frame 2 and the second auxiliary frame 3 are completely consistent in structure, and the length of the first auxiliary frame 2 is less than the length of the support platform 1. The output end of the driving motor 9 is connected to the gear 10 through the driving shaft, and the outer surface of the gear 10 is provided with a driving chain 11, and the outer surface of the driving chain 11 is installed with a connecting column 14, and the end of the connecting column 14 is installed with an auxiliary cover 13, and the outer surface of one side of the auxiliary cover 13 is provided with an auxiliary cover 13, and the outer surface of the auxiliary cover 13 is installed with an auxiliary cylinder 7. The design of the machine 9 and the output shaft can drive the gear 10 to rotate, and the rotation of the gear 10 can drive the driving chain 11 to rotate, and the rotation of the driving chain 11 can synchronously drive the auxiliary cover 13 and the connecting column 14 fixed on the outside of the driving chain 11 to move synchronously, so that the auxiliary cylinder 7 will move synchronously, and the inner ring of the auxiliary cylinder 7 is provided with a built-in groove 16, and a built-in column 17 is installed in the middle of the outer surface of one side of the auxiliary cover 13, and the outer surface of the built-in column 17 is provided with an auxiliary component 15 for auxiliary locking and cleaning, and the auxiliary component 15 includes a hydraulic rod 1501, an end plate 1502 and a cleaning brush 1503, and the output end of the hydraulic rod 1501 is installed with an end plate 1502, and the outer surface of the end plate 1502 is connected with a cleaning brush 1503,The second auxiliary frame 3 is arranged on the side of the outer surface of the support platform 1 away from the first auxiliary frame 2, a bottom plate 12 is installed in the middle of the first auxiliary frame 2, a receiving plate 20 is arranged on the outer surface of the bottom plate 12, a protective layer 8 is installed on the outer surface of the receiving plate 20, an adjusting path 21 is opened in the middle of the bottom plate 12, and a roller 19 is installed in the adjusting path 21. The auxiliary cylinder 7 can be moved to the front and rear sides of the excavator crawler, so that the position of the excavator can be automatically locked. In addition, the design of the hydraulic rod 1501 can drive the end plate 1502 to move, and the end plate 1502 can be moved to the outside of the excavator crawler. The end plate 1502 can be moved to supplement the crawler spacing between the two groups of auxiliary cylinders 7 to achieve stable limiting of the excavator crawler. The number of auxiliary cylinders 7 is convenient for users to install according to their needs, so that the excavator remains stable when it is on the excavator support, and the excavator is prevented from moving in position on the excavator platform. When the excavator moves from the first auxiliary cylinder 7 When the surface of the auxiliary frame 2 leaves, the design of the driving motor 9 and the output shaft can drive the gear 10 to rotate, and the rotation of the gear 10 can drive the driving chain 11 to rotate. The rotation of the driving chain 11 can synchronously drive the auxiliary cover 13 and the connecting column 14 fixed on the outside of the driving chain 11 to move synchronously, so that the auxiliary cylinder 7 will move synchronously, so that the cleaning brush 1503 on the outer surface of the end plate 1502 will contact the receiving plate 20 and the protective layer 8, and the outer surface of the protective layer 8 can be cleaned to prevent the debris carried by the excavator crawler from being on the outer surface of the protective layer 8, affecting the use of the protective layer 8 and the receiving plate 20 again. When the excavator is limited between the two groups of auxiliary cylinders 7, the movement of the auxiliary cylinder 7 can drive the excavator on the outer surface of the protective layer 8, so that the receiving plate 20 can move in the adjustment path 21 using the design of the roller 19, so that the entire receiving plate 20 and the excavator position move about the inside of the first auxiliary frame 2, which is convenient for expanding the working range of the excavator and reducing the limitations of use.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, an adjustment component 6 for auxiliary position adjustment is provided on the outer surface of one side of the first auxiliary frame 2 and the second auxiliary frame 3. The adjustment component 6 is provided with two groups. The adjustment component 6 includes a fixed plate 601, a hydraulic cylinder 602 and a side plate 603. The outer surface of the fixed plate 601 is provided with a hydraulic cylinder 602. The output end of the hydraulic cylinder 602 is installed with a side plate 603. The design of the fixed plate 601 and the hydraulic cylinder 602 can drive the side plate 603 and the first auxiliary frame 2 connected to the side plate 603 to move. The number of adjustment components 6 is designed to facilitate the adjustment of crawler tracks of different models of excavators. The distance between them can be adaptively adjusted. The excavator bracket is conducive to the use of excavators of different models, reducing the limitations of use. The side plate 603 and the first auxiliary frame 2 are integrated into a structure, and the outer surface of the middle bottom of the first auxiliary frame 2 is provided with a guide assembly 18 for auxiliary position movement. The guide assembly 18 includes a side groove 1802 and a pulley 1803, and the pulley 1803 is rotatably installed inside the side groove 1802. The guide assembly 18 also includes a connecting seat 1801 and a slideway 1804, and the end of the pulley 1803 is provided with a connecting seat 1801. The middle of the bracket platform 1 is opened A slide 1804 is provided, and two groups of guide assemblies 18 are provided. The two groups of guide assemblies 18 are symmetrically distributed about the transverse central axis of the slide 1804. The design of the fixed plate 601 and the hydraulic cylinder 602 can drive the side plate 603 and the first auxiliary frame 2 connected to the side plate 603 to move. When the first auxiliary frame 2 moves, the connecting seat 1801 connected to the first auxiliary frame 2 can slide and move inside the slide 1804 through the design of connecting with the pulley 1803, so that the connecting seat 1801 can slide and move inside the slide 1804 by utilizing the design of the fixed plate 601 and the hydraulic cylinder 602. The friction resistance is reduced when the side plate 603 and the first auxiliary frame 2 connected to the side plate 603 are moved, which saves time and effort. By designing that the first auxiliary frame 2 and the second auxiliary frame 3 each correspond to a set of adjustment components 6 and guide components 18, it is convenient to move the first auxiliary frame 2 and the second auxiliary frame 3 separately or to move them to one side at the same time, and to move the longitudinal position of the locked excavator, which is beneficial to adjust the position of the excavator on the support platform 1, and to increase the working range of the excavator. It is convenient for operators to use it without frequently moving the entire excavator support.

[0030] In summary, if Figure 1-Figure 6As shown, the automatically locked excavator support, when the excavator is in use, the design of two sets of independently controlled hydraulic lifting platforms 4 inside the bottom frame 5 can make the support platform 1 lower in height and shift to one side at the same time, so that the support platform 1 is in an inclined state, which is convenient for the excavator to travel to the protective layer 8 on the outer surface of the receiving plate 20. When the excavator travels to the outer surface of the protective layer 8, the receiving plate 20 is fixed to the first auxiliary frame 2 by bolts, which is conducive to the excavator to stably enter the outer surface of the protective layer 8. The protective layer 8 is a crawler floor mat, which can protect the receiving plate 20 and reduce the damage of the excavator crawler to the receiving plate 20. In addition, the design of the hydraulic lifting platform 4 makes the height of the support platform 1 high, which is convenient for the excavator to travel to the outer surface of the protective layer 8. The work at the same height is processed, and then the design of the driving motor 9 and the output shaft can drive the gear 10 to rotate, and the rotation of the gear 10 can drive the driving chain 11 to rotate, and the rotation of the driving chain 11 can synchronously drive the auxiliary cover 13 and the connecting column 14 fixed on the outside of the driving chain 11 to move synchronously, so that the auxiliary cylinder 7 will move synchronously, and then the position of the auxiliary cylinder 7 can be moved to the front and rear sides of the excavator track, so that the position of the excavator can be automatically locked, and in addition, the design of the hydraulic rod 1501 can drive the end plate 1502 to move, and the position of the end plate 1502 can be pressed against the outside of the excavator track, and the position of the end plate 1502 can be moved to the two sets of auxiliary cylinders 7 to complement the crawler track spacing, to achieve stable limiting of the excavator crawler track, the number of auxiliary cylinders 7 is convenient for users to install according to the needs of use, so that the excavator remains stable when it is on the excavator bracket, and the excavator is prevented from moving on the excavator platform. When the excavator leaves the surface of the first auxiliary frame 2, the design of the driving motor 9 and the output shaft can drive the gear 10 to rotate, and the rotation of the gear 10 can drive the driving chain 11 to rotate, and the rotation of the driving chain 11 can synchronously drive the auxiliary cover 13 and the connecting column 14 fixed on the outside of the driving chain 11 to move synchronously, so that the auxiliary cylinder 7 will move synchronously, so that the cleaning brush 1503 on the outer surface of the end plate 1502 will contact the receiving plate 20 and the protective layer 8, The outer surface of the protective layer 8 can be cleaned to prevent the debris carried by the crawler of the excavator from being on the outer surface of the protective layer 8, which will affect the use of the protective layer 8 and the receiving plate 20. When the excavator is limited between the two groups of auxiliary cylinders 7, the movement of the auxiliary cylinders 7 can drive the excavator on the outer surface of the protective layer 8, so that the receiving plate 20 can move in the adjustment path 21 by using the design of the roller 19, so that the entire receiving plate 20 and the excavator position move relative to the first auxiliary frame 2, which is convenient for expanding the working range of the excavator and reducing the limitations of use. Finally, the design of the fixed plate 601 and the hydraulic cylinder 602 can drive the side plate 603 and the first auxiliary frame 2 connected to the side plate 603 to move. When the first auxiliary frame 2 moves,The connection seat 1801 connected to the first auxiliary frame 2 is designed to be connected to the pulley 1803, so that the connection seat 1801 can slide and move inside the slideway 1804, so that the friction resistance can be reduced when the side plate 603 and the first auxiliary frame 2 connected to the side plate 603 are driven to move by the design of the fixed plate 601 and the hydraulic cylinder 602, which is more time-saving and labor-saving.
