Technical Field
[0001] This invention relates to the field of excavator technology, and more specifically, to an easily adjustable excavator support. Background Technology
[0002] An excavator, also known as a digging machine or a soil excavator, is an earthmoving machine that uses a bucket to dig materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile.
[0003] Excavators primarily excavate soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of construction machinery has been relatively rapid, and excavators have become one of the most important pieces of machinery in engineering construction.
[0004] Excavator supports are auxiliary devices used to elevate excavators, increasing their working height or stability. These supports are typically made of strong metal and are height-adjustable as needed. They are usually mounted on the bottom or side of the excavator and their height is controlled by a hydraulic system or other mechanical means.
[0005] Traditional excavator supports have limited height adjustment and poor applicability. When the height adjustment reaches its maximum limit, the bucket still cannot reach the desired working height, highlighting the limitations of existing excavator supports. Furthermore, current excavator supports pose a risk of hindering excavator rotation when the excavator is lowered to its lowest height, creating a safety hazard. Therefore, it is necessary to propose an easily adjustable excavator support to address these issues. Summary of the Invention
[0006] To address the problems existing in the prior art, the purpose of this invention is to provide an easily adjustable excavator support. This solution overcomes the limitations of existing excavator support height adjustment, which makes it difficult to adapt to different working scenarios. Furthermore, when the excavator height is adjusted to its lowest setting, the support poses a safety hazard that can affect the excavator's rotation. The new support offers the advantages of being able to adjust its height according to the operating environment and changing the excavator support height to avoid affecting the excavator's rotation.
[0007] To solve the above problems, the present invention adopts the following technical solution:
[0008] An easily adjustable excavator support includes: tracks, bases symmetrically mounted on the top of the tracks, and a lifting mechanism for supporting the excavator abutting the top surface of the bases. The lifting mechanism includes a lifting seat, which is inserted into the top of the bases.
[0009] The height-increasing seat is provided with an adjustment mechanism, which includes an adjustment groove and a lifting toothed belt.

The lifting toothed belt is fixed on both sides inside the adjustment groove, and the lifting toothed belts on both sides are asymmetrically arranged.
[0010] The adjustment groove is equipped with a lifting mechanism for adjusting the height of the excavator. The lifting mechanism includes a rotating drum, lifting gears, and a positioning shaft. The rotating drum and the positioning shaft are slidably connected in the adjustment groove. The outer end of the rotating drum and one end of the positioning shaft are respectively fixed with the lifting gears.

The bottom of the slot that is slidably connected to it is also provided with a matching conical groove.
[0012] In a preferred embodiment of the present invention, the fixed wing plate at the bottom of the booster seat abuts against the fixed wing plate at the top of the base, the fixed wing plate at the bottom of the upper booster seat abuts against the fixed wing plate at the top of the adjacent lower booster seat, and the two abutting fixed wing plates are fixedly connected by bolts.
[0013] As a preferred embodiment of the present invention, the height-increasing mechanism further includes guide rails and guide grooves. Two guide rails are symmetrically fixed on the outer side of the height-increasing seat, and two guide grooves adapted to the guide rails are symmetrically provided on the inner side.
[0014] As a preferred embodiment of the present invention, the adjustment mechanism further includes a stabilizing bar, a positioning groove, and a pressure column. Two stabilizing bars are symmetrically fixed to the inner side of the adjustment groove between the two lifting toothed belts, and the two stabilizing bars abut against the side of the positioning shaft. The adjustment groove is provided with a positioning groove inside, and the other end of the positioning shaft is slidably connected to the inside of the positioning groove. The pressure column is fixed to the bottom of the stabilizing bar on the heightening seat.
[0015] As a preferred embodiment of the present invention, a support mechanism is installed between the height-increasing mechanisms. The support mechanism includes a support platform, an adjusting motor, and an adjusting gear. The support platform is slidably connected to the height-increasing seat. Four adjusting motors are symmetrically installed on the top surface of the support platform, and the adjusting gear is installed at the output end of each adjusting motor.
[0016] In a preferred embodiment of the present invention, the lifting mechanism further includes support columns, a transmission gear ring, a ring gear, a sun gear, and planetary gears. Four support columns are symmetrically fixed to the side of the support platform, and the rotating drum is rotatably connected to the outside of the support columns. The transmission gear ring is provided on the outer side of the inner end of the rotating drum, and the transmission gear ring meshes with the corresponding adjusting gear. The ring gear is provided on the inner side of the lifting gear fixed to the outer end of the rotating drum. The two sides of the sun gear are rotatably connected to the end of the positioning shaft and the end of the support column, respectively. The planetary gears mesh with the ring gear and the sun gear, respectively, and the ratio of the number of teeth of the sun gear to the number of teeth of the planetary gear is equal to the ratio of the number of teeth of the ring gear to the number of teeth of the planetary gear.

Each anti-detachment mechanism includes a telescopic cover, a return spring, a limiting slider, an anti-detachment plate, a torsion spring shaft, a connecting column, a toggle member, and a sliding groove. Two telescopic covers are symmetrically provided on the top surfaces of the base and the riser. The return spring is installed inside the telescopic cover.

The middle part of the anti-detachment plate is rotatably connected to the top of the stabilizing bar via the torsion spring shaft. Both ends of the anti-detachment plate abut against the limiting slider and the positioning shaft, respectively. The pressure column at the bottom of the adjacent riser abuts against the top surface of the anti-detachment plate. The connecting column is fixed to the bottom of the limiting slider. The toggle member is rotatably connected to the inside of the base and the riser via the torsion spring shaft. One end of the toggle member is provided with the sliding groove, and the connecting column is slidably connected within the sliding groove.
[0018] As a preferred embodiment of the present invention, the end of the actuating member swings within the slot with a conical groove, and the shape of one end of the actuating member swinging within the slot is adapted to the shape of the conical column.
[0019] Compared with the prior art, the advantages of this invention are:
[0020] 1. This device allows for the free addition and reduction of the number of extension mechanisms using a stacking block method, thereby achieving the required working height for the excavator. The assembly process is simple and convenient. To improve the accuracy and stability when two adjacent extension seats are aligned, matching grooves and blocks, as well as slots and posts, are provided on the top and bottom surfaces of the extension seats. This allows for quick and precise alignment between adjacent extension seats or bases and extension seats, greatly improving the stability of the extension mechanism and preventing wobbling and offset. After assembly, the adjustment mechanisms inside the extension seats remain interconnected, and the lifting mechanism can smoothly slide within the adjustment grooves. The lifting mechanism drives the support mechanism to rise and fall, thereby raising and lowering the excavator mounted on the support platform to adjust the excavator's working height. The quick-install and detachable extension mechanism allows for convenient adjustment of the excavator support height according to actual working needs, making the operation simple, fast, and highly adaptable.
[0021] 2. An anti-detachment mechanism is also provided at the top of the adjustment slot. When the riser is spliced with the base or another riser, the lower anti-detachment plate can be automatically rotated 90 degrees, thereby opening the adjustment slot and allowing the lifting mechanism to slide freely in the adjustment slot. The anti-detachment plate on the top riser is restricted by the limit slider and cannot rotate in the direction of force on the anti-detachment plate. Therefore, it can prevent the lifting mechanism from detaching from the adjustment slot and improve the safety of the device. Attached Figure Description

[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 a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0033] like Figure 1-8 As shown, an easily adjustable excavator support includes tracks 1, bases 2 symmetrically mounted on the top of the tracks 1, and a lifting mechanism 3 for supporting the excavator connected to the top surface of the bases 2. The lifting mechanism 3 includes a lifting seat 31, which is inserted into the top of the bases 2.
[0034] The height-increasing seat 31 is provided with an adjustment mechanism 4, which includes an adjustment groove 41 and a lifting toothed belt 42. The adjustment groove 41 is located inside the base 2 and the height-increasing seat 31, and the adjustment groove 41 on the base 2 and the adjustment groove 41 on the height-increasing seat 31 are connected end to end. The lifting toothed belt 42 is fixed on both sides inside the adjustment groove 41, and the lifting toothed belt 42 on both sides is asymmetrically arranged.
[0035] The adjustment groove 41 is equipped with a lifting mechanism 6 for adjusting the height of the excavator. The lifting mechanism 6 includes a rotating drum 62, lifting gears 64 and a positioning shaft 66. The rotating drum 62 and the positioning shaft 66 are slidably connected in the adjustment groove 41. The outer end of the rotating drum 62 and one end of the positioning shaft 66 are respectively fixed with lifting gears 64, and the two lifting gears 64 are respectively meshed with the lifting toothed belts 42 on both sides of the adjustment groove 41, and the two lifting gears 64 rotate in opposite directions.
[0036] In a further embodiment, when it is necessary to raise the height of the excavator, simply stack an appropriate number of extension struts 31 as needed. The adjustment mechanisms 4 inside the added extension struts 31 are interconnected, and the lifting mechanism 6 can smoothly rise and fall within the adjustment groove 41, thereby driving the excavator to rise and fall via the support platform 51, achieving the purpose of adjusting the excavator's working height. Utilizing the quick-installing and removable extension mechanism 3, the height of the excavator support can be conveniently adjusted according to actual working needs, the operation process is simple and quick, and its applicability is enhanced.
[0037] Specifically, the height-increasing mechanism 3 also includes a fixed wing plate 32, a docking groove 35, a slot 36, a docking block 37, a pin 38, and a conical column 39. The fixed wing plate 32 is fixed to the top of both sides of the base 2 and the upper and lower ends of both sides of the height-increasing seat 31. The top surface of the base 2 and the height-increasing seat 31 is provided with a docking groove 35. The four corners of the docking groove 35 are provided with four slots 36. The bottom surface of the height-increasing seat 31 is provided with a docking block 37 that matches the docking groove 35. The upper docking block 37 is slidably connected to the adjacent lower docking groove 35. The four corners of the docking block 37 are fixed with four pins 38. Each upper pin 38 is slidably connected to the adjacent lower slot 36. The bottom of the two pins 38 near the inner side of the base 2 and the height-increasing seat 31 is fixed with a conical column 39. The bottom of the slot 36 that is slidably connected to it is also provided with a matching conical groove.
[0038] In a further embodiment, one of the most important features of this device is that the number of raising mechanisms 3 can be freely increased or decreased in a stacking manner to achieve the working height required by the excavator, and the assembly process is simple and convenient. In order to improve the accuracy and stability when two adjacent raising seats 31 are connected, matching docking grooves 35 and docking blocks 36, as well as slots 36 and inserts 38 are respectively provided on the top and bottom surfaces of the raising seats 31. The matching of docking blocks 36 and docking grooves 35 can quickly and accurately align the two raising seats 31, improving their verticality. Combined with the cooperation of slots 36 and inserts 38, the stability of the raising mechanism 3 is further improved, avoiding shaking and displacement.
[0039] Specifically, the fixed wing plate 32 at the bottom of the riser 31 abuts against the fixed wing plate 32 at the top of the base 2, and the fixed wing plate 32 at the bottom of the upper riser 31 abuts against the fixed wing plate 32 at the top of the adjacent lower riser 31, and the two abutting fixed wing plates 32 are fixedly connected by bolts.
[0040] In a further embodiment, the fixed wing plate 32 increases the contact area between the base 2 and the riser 31 or two adjacent risers 31, and then the fixed wing plate 32 is connected by bolts to fix the two adjacent risers 31 or the riser 31 to the base 2, thereby improving the overall integrity and stability and preventing the riser mechanism 3 from shaking or tipping over.
[0041] Specifically, the height-increasing mechanism 3 also includes guide rails 33 and guide grooves 34. Two guide rails 33 are symmetrically fixed on the outer side of the height-increasing seat 31, and two guide grooves 34 adapted to the guide rails 33 are symmetrically provided on the inner side.
[0042] In a further embodiment, when adding or removing the height-increasing seat 31, the guide rail 33 on the added or removed height-increasing seat 31 can be slid within the guide groove 34 on the assembled height-increasing mechanism 3, thereby facilitating transportation and handling.
[0043] Specifically, the adjustment mechanism 4 also includes a stabilizing bar 43, a positioning groove 44, and a pressure column 45. Two stabilizing bars 43 are symmetrically fixed on the inner side of the adjustment groove 41 between the two lifting toothed belts 42, and the two stabilizing bars 43 abut against the side of the positioning shaft 66. The adjustment groove 41 is provided with a positioning groove 44, and the other end of the positioning shaft 66 is slidably connected to the inside of the positioning groove 44. The bottom of the stabilizing bar 43 on the heightening seat 31 is fixed with a pressure column 45.
[0044] In a further embodiment, two symmetrically arranged stabilizing bars 43 in the adjusting groove 41 clamp the positioning shaft 66 of the lifting mechanism 6, preventing the entire lifting mechanism 6 from shaking during sliding within the adjusting groove 41. This improves the stability of the support mechanism 5 connected to the lifting mechanism 6, thereby ensuring the safety and stability of the excavator during operation. The positioning groove 44 provides support and restriction for the positioning shaft 66, regulating its sliding trajectory and preventing shaking, thus allowing the lifting gear 64 fixed on the positioning shaft 66 to stably mesh with the lifting belt 42. When the upper layer of the riser seat 31 is spliced with the base 2 or when the upper layer of the riser seat 31 is spliced with the lower layer of the adjacent riser seat 31, the pressure column 45 at the bottom of the upper layer of the riser seat 31 can push the anti-detachment plate 74 on the top surface of the base 2 or the top surface of the lower layer of the adjacent riser seat 31, thereby releasing the anti-detachment plate 74 from blocking the adjusting groove 41 and allowing the lifting mechanism 6 to smoothly rise and fall within the adjusting groove 41.
[0045] Specifically, a support mechanism 5 is installed between the height-increasing mechanisms 3. The support mechanism 5 includes a support platform 51, an adjusting motor 52, and an adjusting gear 53. The support platform 51 is slidably connected to the height-increasing seat 31. Four adjusting motors 52 are symmetrically installed on the top surface of the support platform 51, and an adjusting gear 53 is installed at the output end of each adjusting motor 52.
[0046] In a further embodiment, the support platform 51 is used to mount the excavator. The adjustment motor 52 on the support platform 51 drives the adjustment gear 53 to rotate. The adjustment gear 53 cooperates with the transmission gear 63 on the rotating drum 62 to drive the lifting mechanism 6 to rise and fall within the adjustment mechanism 4, thereby realizing the lifting and lowering of the support platform 51 and driving the excavator to change its height.
[0047] Specifically, the lifting mechanism 6 also includes a support column 61, a transmission gear ring 63, a ring gear 65, a sun gear 67, and a planetary gear 68. Four support columns 61 are symmetrically fixed on the side of the support platform 51, and the rotating drum 62 is rotatably connected to the outside of the support column 61. The inner end of the rotating drum 62 is provided with a transmission gear ring 63, and the transmission gear ring 63 is meshed with the corresponding adjusting gear 53. The inner side of the lifting gear 64 fixed to the outer end of the rotating drum 62 is provided with a ring gear 65. The two sides of the sun gear 67 are rotatably connected to the end of the positioning shaft 66 and the end of the support column 61, respectively. The planetary gear 68 is meshed with the ring gear 65 and the sun gear 67, respectively, and the ratio of the number of teeth of the sun gear 67 to the number of teeth of the planetary gear 68 is equal to the ratio of the number of teeth of the ring gear 65 to the number of teeth of the planetary gear 68.
[0048] In a further embodiment, the adjusting motor 52 drives the rotating drum 62 to rotate, which in turn drives the lifting gear 64 at its end to rotate. The lifting gear 64 meshes with the corresponding lifting toothed belt 42 on the adjusting groove 41, enabling the lifting mechanism 6 to move up and down within the adjusting groove 41. Simultaneously, the rotation of the lifting gear 64 drives the planetary gear 68 to rotate via the ring gear 65 on its inner ring. The planetary gear 68, through the sun gear 67, drives the positioning shaft 66 to rotate in the opposite direction (the rotation direction of the positioning shaft 66 is always opposite to the rotation direction of the rotating drum 62). Therefore, the rotation directions of the lifting gear 64 on the positioning shaft 66 and the lifting gear 64 at the end of the rotating drum 62 are also opposite. Since the lifting toothed belts 42 meshing with the two lifting gears 64 are located on opposite sides of the two lifting gears 64, they achieve the same effect (synchronous rising or falling), but the resulting support force and balance are more stable, effectively improving the stability of the lifting mechanism 6 sliding within the adjusting groove 41. The ratio of the number of teeth of the sun gear 67 to the number of teeth of the planetary gear 68 is equal to the ratio of the number of teeth of the ring gear 65 to the number of teeth of the planetary gear 68, which can keep the rotation speed of the two lifting gears 64 consistent, thereby achieving the purpose of synchronous lifting of the rotating drum 62 and the positioning shaft 66.
[0049] Specifically, the top surfaces of both the base 2 and the riser 31 are symmetrically equipped with two sets of anti-detachment mechanisms 7. Each anti-detachment mechanism 7 includes a telescopic cover 71, a return spring 72, a limiting slider 73, an anti-detachment plate 74, a torsion spring shaft 75, a connecting column 76, a toggle element 77, and a sliding groove 78. The top surfaces of the base 2 and the riser 31 are symmetrically equipped with two telescopic covers 71. A return spring 72 is installed inside the telescopic cover 71. The limiting slider 73 is slidably connected inside the telescopic cover 71, and the limiting slider 73 abuts against the return spring 72, preventing detachment. The middle part of the anti-detachment plate 74 is rotatably connected to the top of the stabilizing bar 43 via a torsion spring shaft 75, and the two ends of the anti-detachment plate 74 abut against the limiting slider 73 and the positioning shaft 66 respectively. The pressure column 45 at the bottom of the adjacent upper layer of the heightening seat 31 abuts against the top surface of the anti-detachment plate 74. The bottom of the limiting slider 73 is fixed with a connecting column 76. The actuating member 77 is rotatably connected to the interior of the base 2 and the heightening seat 31 via a torsion spring shaft 75. One end of the actuating member 77 is provided with a sliding groove 78, and the connecting column 76 is slidably connected in the sliding groove 78.
[0050] In a further embodiment, the top of the adjustment groove 41 on the uppermost height-increasing seat 31 is provided with an anti-detachment mechanism 7. In its natural state, the limiting slider 73 at this location is pushed out by the return spring 72 inside the telescopic cover 71, and the limiting slider 73 abuts against one end of the anti-detachment plate 74. When the positioning shaft 66 inside the adjustment groove 41 rises and hits the anti-detachment plate 74 (the impact force is from bottom to top, see attached drawing), Figure 2 (The same applies below) Due to the resistance of the limit slider 73, the anti-detachment plate 74 cannot rotate, thereby blocking the positioning shaft 66 and preventing the lifting mechanism 6 from disengaging from the adjustment groove 41. During the process of the upper riser 31 being connected to the top of the base 2 or the top of the lower adjacent riser 31, the docking block 37 at the bottom of the upper riser 31 is first inserted into the docking groove 35 on the top surface of the base 2 or the lower adjacent riser 31, and the insert 38 is inserted into the slot 38. When the insert post 38 near the inner side of the riser seat 31 is inserted into the slot 38, the cone post 39 at its bottom presses the actuating member 77 in the slot 38. The actuating member 77 swings to one side and rotates around the torsion spring shaft 75 on it, compressing the torsion spring shaft 75. At the same time, the other end of the actuating member 77 pushes the limiting slider 73 into the telescopic cover 71 through the cooperation of the sliding groove 78 and the connecting post 76. The limiting slider 73 compresses the return spring 72. At the same time, the other end of the limiting slider 73 disengages from the anti-detachment plate 74 and no longer abuts against the anti-detachment plate 74. Subsequently, the pressure post 45 at the bottom of the upper stabilizing bar 43 abuts against the top surface of the anti-detachment plate 74 at the top of the lower stabilizing bar 43, causing the anti-detachment plate 74 to tilt upward at one end of the adjustment groove 41 until it is in a vertical state. At this time, the adjustment grooves 41 between the upper and lower adjacent riser seats 31 and base 2 or between riser seats 31 are connected and connected. The lifting mechanism 6 can slide smoothly between the two adjustment grooves 41.
[0051] Specifically, the end of the toggle 77 swings within the slot 36 with a conical groove, and the shape of one end of the toggle 77 swinging within the slot 36 is adapted to the shape of the conical column 39.
[0052] In a further embodiment, one end of the actuating member 77 is configured to be adapted to the shape of the cone 39 so that the cone 39 can be inserted into the slot 36 and the actuating member 77 can be pushed to one side smoothly, thereby avoiding the actuating member 77 from obstructing the cone 39 and the insert 38 from entering the slot 36, and at the same time achieving the purpose of the cone 39 and the insert 38 causing the actuating member 77 to swing.
[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
