Description

Technical Field

[0001] This application relates to the technical field of vibration compaction equipment, and particularly to a coarse-grained soil vibration compactor. Background Art

[0002] A coarse-grained soil vibration compactor generates vibration through a vibration motor, causing the rammer plate to apply a vertical vibration load to the surface of the specimen, rearranging the soil particles and reducing voids to achieve maximum compaction.

[0003] The existing Chinese patent document with the application number 202410247402.5 discloses a surface vibration compactor for coarse-grained soil, including a frame, a lifting mechanism and a rotating mechanism installed on the frame. The test cylinder is placed at the lower end of the frame and fixed by fixing claws. Then the lifting mechanism drives the vibration mechanism to descend, so that the rammer seat of the vibration mechanism abuts against the test cylinder, and then vibration compaction is carried out.

[0004] In the vibration mechanism, the rammer seat is detachably installed by multiple bolts. The lower end of the rammer seat has a disc-shaped part, and the diameter of the disc part at the lower end of the rammer seat is close to the inner diameter of the test cylinder. During the compaction process, the lower end of the rammer seat extends into the test cylinder. Usually, two test cylinders with different diameters and two corresponding different rammer seats are provided in the vibration compactor to prepare specimens with different diameters. When using different test cylinders, it is necessary to remove multiple bolts to disassemble the rammer seat, and then install another rammer seat, which is rather troublesome in operation. Summary of the Invention

[0005] In order to reduce the working intensity of disassembly, this application provides a coarse-grained soil vibration compactor.

[0006] This application adopts the following technical solutions: A coarse-grained soil vibration compactor includes a frame, a vibration mechanism and a lifting mechanism for driving the vibration mechanism to move up and down. The vibration mechanism includes a vibration part connected to the lifting mechanism and a rammer column installed at the lower end of the vibration part. A rammer plate is coaxially fixed at the lower end of the rammer column. A fixing ring is provided on the frame, and a rammer ring is detachably installed on the inner wall of the fixing ring. The inner diameter of the rammer ring is the same as the outer diameter of the rammer plate and they are coaxially arranged. When the vibration mechanism moves up and down, the rammer plate can pass through the rammer ring. A first positioning member is provided between the rammer plate and the rammer ring, and a second positioning member is provided between the rammer ring and the fixing ring. When the first positioning member connects the rammer plate and the rammer ring together, the second positioning member releases the positioning state of the fixing ring and the rammer ring. When the first positioning member releases the positioning state of the rammer ring and the rammer plate, the second positioning member connects the rammer ring and the fixing ring together.

[0007] By adopting the above technical solution, when using a small test cylinder, the ramming ring is installed on the fixed ring through the second positioning member, so that the ramming plate can compact the small test cylinder; when using a large test cylinder, the ramming plate moves to the central position of the ramming ring, and then is connected to the ramming ring through the first positioning member, and the connection between the ramming ring and the fixed ring is released, so that the ramming ring is installed on the ramming plate, adapts to the inner diameter of the large test cylinder, and compacts it.

When the rotating plate rotates, the arc-shaped edge can abut against the penetrating rod and push the penetrating rod to slide.

[0011] By adopting the above technical solution, the rotating plate rotates, so that the arc-shaped edge abuts against the penetrating rod and pushes the penetrating rod to slide, thereby driving the sliding of the positioning rod. When the rotating plate resets, the first elastic member can drive the positioning rod to slide back into the sliding groove.

[0012] Optionally, an extension cylinder is coaxially arranged on the rotating plate, a plug rod is slidably arranged up and down on the side wall of the extension cylinder, and a jack for the plug rod to be plugged into is formed on the ramming plate; after the arc-shaped edge pushes the positioning rod to be plugged into the plugging groove, the plug rod can pass through the rotating plate downward and be plugged into the jack.

[0013] By adopting the above technical solution, the plug rod passes through the rotating plate and is plugged into the jack, so that the rotating plate is not easily rotated again, and the positioning effect on the positioning rod is improved.

[0014] Optionally, a positioning groove is provided on the inner wall of the fixing ring, and a receiving groove is provided on the ramming ring, and the second positioning member includes a connecting rod slidably set in the receiving groove and a second elastic member installed in the receiving groove, and the second elastic member provides a force for the connecting rod to be inserted into the positioning groove; the positioning rod is an internal hollow structure, and a power source is installed in the positioning rod, and the power source and the insertion rod are linked, and when the positioning rod is inserted into the insertion groove, the insertion rod is inserted into the socket and drives the power source to slide, so that the power source drives the connecting rod to slide out of the positioning groove.

[0015] By adopting the above technical solution, when the positioning rod is inserted into the insertion groove, the connecting rod is driven by the power source to slide out of the positioning groove, thereby releasing the positioning effect of the tamping ring and the fixing ring.

[0016] Optionally, a yield groove is provided between the accommodating groove and the plug-in groove, and a convex seat extending in the yield groove is provided on the side wall of the connecting rod; the power source includes a sliding plate slidably arranged in the positioning rod and a hooking edge arranged on the sliding plate, the sliding groove is provided with a through groove connected to the insertion hole, and the sliding plate is provided with an extension rod slidably passing through the positioning rod and plugged into the through groove, and a third elastic member is provided between the sliding plate and the inner end surface of the positioning rod; a long groove opposite to the yield groove is provided on the side wall of the positioning rod; the end of the hooking edge extends into the long groove, and a resistance part is provided in the positioning rod, and when the insertion rod drives the sliding plate to slide through the extension rod, the resistance part can drive one end of the hooking edge to extend into the yield groove and abut against the convex seat, so that the sliding plate drives the convex seat to move.

[0017] By adopting the above technical solution, the hook edge is deformed under the action of the abutment portion and abuts against the convex seat. When the sliding plate drives the hook edge to slide, the connecting rod is synchronously driven to slide through the convex seat.

[0018] Optionally, the resistance part includes a mounting rod fixed to the inner wall of one end of the positioning rod away from the through slot, and a resistance block arranged at the end of the mounting rod, and the hook is in contact with the resistance block along the side wall.

[0019] Optionally, a through hole is provided on the extension rod, and a resistance surface is obliquely provided at the lower end of the insertion rod, so that when the insertion hole passes downward through the through hole, the extension rod is driven to slide in a direction away from the positioning rod.

[0020] By adopting the above technical solution, the effect of the through rod pushing the extension rod to slide is achieved.

[0021] Optionally, a threaded ring is arranged on the extension cylinder in a threaded manner, a rotating ring is rotatably arranged at the lower end of the threaded ring, and the insertion rod is arranged on the rotating ring.

[0022] By adopting the above technical solution, it is convenient to operate the up and down movement of the insertion rod.
