Description

Technical Field

[0001] The present invention relates to the field of rammers, and particularly to a multi-directional rammer and its usage method. Background Art

[0002] A rammer (also known as a percussion rammer) is a special compaction device used to compact fillers or soft foundations. It is usually installed on a loader and powered by the hydraulic system of the loader, having good mobility, high efficiency, and controllability. It mainly includes devices such as a rammer frame, a hydraulic cylinder, a rammer hammer, and a compaction plate.

[0003] The invention patent with the authorization announcement number CN 103741669 B discloses a self-propelled intelligent continuous dynamic compaction machine, which realizes the lifting and front-back swinging of the front compaction mechanism through a linkage mechanism. However, when compacting a roadside slope, since the compaction mechanism can only swing back and forth, it is impossible to compact the roadside slope. The rammer can only face the roadside and realize the compaction of the slope through the front-back swinging of the compaction mechanism. However, this machine position makes the movement of the rammer very complicated (the rammer cannot move horizontally), resulting in extremely low compaction efficiency. Therefore, a rammer is needed that can move the compaction mechanism to the side and can swing left and right to realize the compaction of the roadside slope. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a multi-directional rammer and its usage method.

[0005] The present invention is realized through the following technical solutions. A multi-directional rammer is provided, which includes a compaction mechanism, a walking vehicle, and a lifting frame located in front of the walking vehicle. The lifting frame is connected to the walking vehicle through a linkage mechanism, and further includes a lifting oil cylinder for driving the lifting of the lifting frame. One side of the compaction mechanism is hinged to the lifting frame, and a swinging oil cylinder for driving the compaction mechanism to swing to the side of the walking vehicle is installed on the lifting frame. The compaction mechanism includes a compaction frame hinged to the lifting frame, two adjusting frames arranged front and back and vertically slidably connected in the compaction frame, and a lower rammer located between the two adjusting frames. Vertical racks are provided on the sides of the two adjusting frames close to each other, and arc teeth adapted to the racks are provided at the front and rear ends of the lower rammer. The compaction mechanism further includes a sliding frame vertically slidably connected to the compaction frame and a driving oil cylinder for driving the sliding frame to lift. Two movable pulleys are installed on the driving sliding frame, and the two adjusting frames are respectively connected to the compaction frame through steel wires bypassing the movable pulleys, and at least one steel wire is connected to the compaction frame through an adjusting oil cylinder.

[0006] In this solution, the lifting oil cylinder drives the compaction mechanism to lift. When the compaction mechanism descends, compaction is achieved; when the compaction mechanism ascends, transfer and traveling are realized. In the compaction mechanism, the driving oil cylinder drives two movable pulleys to lift, thereby realizing the synchronous lifting of two adjustment frames, and then driving the lower rammer to lift for compaction work. By extending and retracting the adjustment oil cylinder, the lifting of a single adjustment frame is realized, thereby adjusting the relative height of the two adjustment frames. Through the meshing of the rack and the arc teeth, the lower rammer swings, making the compaction surface of the lower rammer tilt back and forth, realizing the compaction of the front and back inclined surfaces. At this time, it is in the front compaction state. The compaction mechanism is driven by the swing oil cylinder to swing. After the compaction mechanism swings 90 degrees, it swings to the side of the walking vehicle. At this time, the compaction surface of the lower rammer swings left and right, thereby realizing the compaction of the left and right inclined surfaces. At this time, it is in the side compaction state.

[0007] As an optimization, the link mechanism includes an upper link and a lower link. The front ends of the upper link and the lower link are both hinged to the lifting frame, and the rear ends of the upper link and the lower link are both hinged to the walking vehicle. The upper link and the lower link in this solution realize the connection between the lifting frame and the walking vehicle.

[0008] As an optimization, the hinge points at both ends of the upper link and the hinge points at both ends of the lower link form a parallelogram. In this solution, the hinge points at both ends of the upper link and the hinge points at both ends of the lower link form a parallelogram, so that the lifting frame can lift in a constant posture.

[0009] As an optimization, one steel wire rope is connected to the lower end of the compaction frame, and the other steel wire rope is connected to the telescopic shaft of the adjustment oil cylinder. The adjustment oil cylinder is installed at the lower end of the compaction frame. In this solution, one steel wire rope is connected to the telescopic shaft of the adjustment oil cylinder. By extending and retracting the adjustment oil cylinder, the adjustment frame connected to this steel wire rope can be driven to lift alone.

[0010] As an optimization, the right end of the compaction mechanism is hinged to the right end of the lifting frame, the swing oil cylinder is hinged to the upper end of the lifting frame, and the telescopic shaft of the swing oil cylinder is hinged to the compaction mechanism.

[0011] As an optimization, the arc teeth are arranged at the upper end of the lower rammer. A plurality of rammer blocks are stacked on the lower rammer, and a limiting side plate for restricting the front and back movement of the rammer blocks is fixedly connected to the adjustment frame. The rammer blocks in this solution improve the ramming force. When the lower rammer tilts, the rammer blocks tilt, and the limiting side plate keeps the rammer blocks directly above the lower rammer.

[0012] As an optimization, the limiting side plate is a U-shaped plate, and the end of the rammer block is inserted into the U-shaped plate. In this solution, the end of the rammer block is inserted into the U-shaped plate, realizing the limitation of the length and width directions of the rammer block.

[0013] As an optimization, the total height of multiple rammer blocks is greater than the height of the lower rammer, and lubricating oil is applied between adjacent rammer blocks. In this solution, lubricating oil is applied between adjacent rammer blocks to facilitate the offset between adjacent rammer blocks and reduce friction.

[0014] A method for using a multi-directional rammer includes the following steps:

[0015] a. Drive the ramming mechanism to rise and fall through a lifting oil cylinder. The ramming mechanism descends to achieve ramming, and the ramming mechanism rises to achieve traveling.

[0016] b. The drive oil cylinder in the ramming mechanism drives two movable pulleys to rise and fall, thereby realizing the synchronous rise and fall of two adjustment frames, and then driving the lower rammer to rise and fall for ramming work.

[0017] c. The telescopic movement of the adjustment oil cylinder realizes the rise and fall of a single adjustment frame, thereby adjusting the relative height of the two adjustment frames. The engagement of the rack and the arc-shaped teeth realizes the swing of the lower rammer, making the ramming surface of the lower rammer tilt forward and backward, and realizing the ramming of the front and rear inclined surfaces. At this time, it is in the front ramming state.

[0018] d. When the lower rammer tilts, the rammer blocks tilt, and the rammer blocks are located directly above the lower rammer through the limit side plates.

[0019] e. Drive the ramming mechanism to swing through a swing oil cylinder, so that the ramming mechanism swings 90 degrees and then swings to the side of the walking vehicle. At this time, the ramming surface of the lower rammer swings left and right, thereby realizing the ramming of the left and right inclined surfaces. At this time, it is in the side ramming state.

[0020] The beneficial effects of the present invention are as follows: A multi-directional rammer and its using method of the present invention can realize the front and rear inclination of the ramming surface through the front and rear swing of the rammer of the ramming mechanism itself, so as to ram the ground with front and rear inclination in front of the walking vehicle. The ramming mechanism swings 90 degrees through the swing oil cylinder and then swings to the side of the walking vehicle. At this time, the ramming surface of the lower rammer swings left and right, thereby realizing the ramming of the left and right inclined surfaces. At this time, it is in the side ramming state, thus improving the ramming direction of the rammer and adapting to more road conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] To clearly illustrate the technical features of this solution, the following describes this solution through specific embodiments.

[0031] As Figures 1 - 7 shown, a multi-directional ramming machine of the present invention includes a ramming mechanism 1, a traveling vehicle 2, and a lifting frame 6 located in front of the traveling vehicle 2. The traveling vehicle generally uses a loader and realizes traveling through a crawler mechanism to improve cross-country performance.

[0032] The lifting frame 6 is connected to the traveling vehicle 2 through a linkage mechanism. The linkage mechanism includes an upper connecting rod 3 and a lower connecting rod 4. Both the upper connecting rod 3 and the lower connecting rod 4 extend forward and backward. There are two upper connecting rods 3 arranged side by side left and right, and there are two lower connecting rods 4 arranged side by side left and right.

[0033] The front ends of the upper connecting rod 3 and the lower connecting rod 4 are both hinged to the lifting frame 6, and the hinge shafts both extend horizontally left and right. The rear ends of the upper connecting rod 3 and the lower connecting rod 4 are both hinged to the traveling vehicle 2, and the hinge shafts also both extend horizontally left and right.

[0034] The hinge points at both ends of the upper connecting rod 3 and the hinge points at both ends of the lower connecting rod 4 form a parallelogram, so that the lifting frame 6 can be lifted while maintaining a constant posture, preventing the lifting frame 6 from tilting forward, backward, left, or right.

[0035] It also includes a lifting oil cylinder 5 for driving the lifting of the lifting frame 6. The front end of the lifting oil cylinder 5 is hinged to the lower connecting rod 4, and the rear end is hinged to the traveling vehicle 2. By the lifting of the lifting oil cylinder 5, the lower connecting rod 4 swings up and down, thereby realizing the lifting of the lifting frame 6.

[0036] When the ramming machine is in the traveling state, the lifting frame 6 rises to prevent contact with the ground. When ramming work is carried out, the lifting frame 6 descends for ramming.

[0037] The ramming mechanism 1 is located in front of the lifting frame 6. One side of the ramming mechanism 1 is hinged to the lifting frame 6 and the hinge axis is vertically arranged. A swing oil cylinder 7 for driving the ramming mechanism 1 to swing to the side of the walking vehicle 2 is installed on the lifting frame 6. In this embodiment, the right end of the ramming mechanism 1 is hinged to the right end of the lifting frame 6, and the right end of the lifting frame 6 extends rightward to a position flush with the side of the walking vehicle 2, so that after the ramming mechanism 1 swings 90 degrees, it swings to the right side of the walking vehicle 2, facilitating ramming of the right-side road surface, as Figure 3 shown.

[0038] The swing oil cylinder 7 is hinged to the upper end of the lifting frame 6, and the telescopic shaft of the swing oil cylinder 7 is hinged to the ramming mechanism 1, so as to realize the swing of the ramming mechanism 1 through the telescopic movement of the swing oil cylinder 7.

[0039] When the ramming mechanism 1 is located in front of the lifting frame 6, it is in the front ramming state. After the ramming mechanism 1 swings 90 degrees to the right, it swings to the right side of the walking vehicle 2 and is in the side ramming state.

[0040] As Figures 4 - 7 shown, the ramming mechanism 1 includes a ramming frame 11 hinged to the lifting frame 6, two adjusting frames 12 arranged front and rear and vertically slidably connected within the ramming frame 11, and a lower rammer 13 located between the two adjusting frames 12.

[0041] The ramming frame 11 is a vertically long rectangular frame structure. The adjusting frames 12 are vertically long strips and are vertically slidably connected to the ramming frame 11 through slide rails and sliders. The adjusting frames 12 are located inside the ramming frame 11. When the ramming mechanism 1 is in the front ramming state, the two adjusting frames 12 are arranged front and rear along the traveling direction of the walking vehicle 2. When the ramming mechanism 1 is in the side ramming state, the two adjusting frames 12 are arranged left and right along the traveling direction of the walking vehicle 2.

[0042] As Figure 7 shown, vertical racks 5 are provided on the mutually approaching sides of the two adjusting frames 12. Arc-shaped teeth 14 adapted to the racks 5 are provided at the front and rear ends of the lower rammer 13. The arc-shaped teeth 14 at the front and rear ends of the lower rammer 13 are concentrically arranged, so that when the heights of the two adjusting frames 12 change relatively, the arc-shaped teeth 14 are always meshed with the racks 5. The length of the arc-shaped teeth 14 covers the entire length of the lower rammer 13, thereby increasing the meshing length and preventing tooth breakage.

[0043] The ramming mechanism 1 further includes a sliding frame 18 vertically slidably connected to the ramming frame 11 and a driving oil cylinder 21 for driving the sliding frame 18 to lift. The sliding frame 18 is vertically slidably connected to the right side outside the ramming frame 11. Two movable pulleys 19 are installed on the driving sliding frame 18. The two adjusting frames 12 are respectively connected to the ramming frame 11 through steel wires 20 bypassing the movable pulleys 19, so as to drive the two adjusting frames 12 to lift synchronously through the lifting of the sliding frame 18, and the lifting distance of the adjusting frames 12 is twice the lifting distance of the sliding frame 18.

[0044] At least one steel wire rope 20 is connected to the ramming frame 11 by an adjusting oil cylinder 22. In this embodiment, one of the steel wire ropes 20 is connected to the lower end of the ramming frame 11, and the other steel wire rope 20 is connected to the telescopic shaft of the adjusting oil cylinder 22. The adjusting oil cylinder 22 is installed at the lower end of the ramming frame 11, so as to drive the single adjusting frame 12 to lift and lower through the telescopic movement of the adjusting oil cylinder 22.

[0045] The arc-shaped teeth 14 are arranged at the upper end of the lower rammer 13. A plurality of rammer blocks 16 are stacked on the lower rammer 13. The area of the rammer blocks 16 is close to the top surface area of the lower rammer 13. The total height of the plurality of rammer blocks 16 is greater than the height of the lower rammer 13. Lubricating oil is applied between adjacent rammer blocks 16. The purpose of arranging the rammer blocks 16 is to increase the ramming force. At the same time, when the lower rammer 13 swings, the rammer blocks 16 will not swing left and right, so as not to interfere with other structures, reducing the volume of the ramming mechanism 1 while ensuring the weight of the rammer.

[0046] A limiting side plate 17 for restricting the front and rear movement of the rammer block 16 is fixedly connected to the adjusting frame 12. The limiting side plate 17 is a U-shaped plate. The end of the rammer block 16 is inserted into the U-shaped plate. One end of the rammer block 16 close to the limiting side plate 17 is arc-shaped, so that when the rammer block 16 is tilted, the distance from the limiting side plate 17 changes very little, and the limiting side plate 17 can play a good limiting role.

[0047] A using method of a multi-directional ramming machine includes the following steps:

[0048] a. Drive the ramming mechanism 1 to lift and lower through the lifting oil cylinder 5. The ramming mechanism 1 descends to achieve ramming, and the ramming mechanism 1 ascends to achieve transfer and travel;

[0049] b. The driving oil cylinder 21 in the ramming mechanism 1 drives the two moving pulleys 19 to lift and lower, so as to realize the synchronous lifting and lowering of the two adjusting frames 12, and then drive the lower rammer 13 to lift and lower for ramming work;

[0050] c. Realize the lifting and lowering of a single adjusting frame 12 through the telescopic movement of the adjusting oil cylinder 22, so as to adjust the relative height of the two adjusting frames 12. Through the meshing of the rack 5 and the arc-shaped teeth 14, the lower rammer 13 swings, making the ramming surface of the lower rammer tilt back and forth to achieve ramming of the front and rear inclined surfaces. At this time, it is in the front ramming state;

[0051] d. When the lower rammer is tilted, the rammer block 16 is tilted, and the rammer block 16 is located directly above the lower rammer 13 through the limiting side plate 17;

[0052] e. Drive the ramming mechanism 1 to swing through the swing oil cylinder 7, so that the ramming mechanism 1 swings 90 degrees and then swings to the side of the walking vehicle 2. At this time, the ramming surface of the lower rammer 13 swings left and right, so as to realize ramming of the left and right inclined surfaces. At this time, it is in the side ramming state.
