Description

Technical Field

[0001] This utility model relates to the field of hydraulic vibratory compactor technology, specifically a mobile hydraulic plate vibratory compactor. Background Technology

[0002] A vibratory plate compactor is a compactor that uses the vibration of a vibrating plate to compact the road surface. It primarily utilizes internal mechanical power to cause permanent deformation and densification of the compacted layer. Suitable for various compaction operations, the compactor works by having a hydraulic cylinder lift the hammer to a set height and then rapidly apply reverse force. Under the combined action of gravity and the hydraulic cylinder's thrust, the hammer accelerates downwards. Upon impact, the hammer strikes the assembly between the hammer and the compactor plate, driving the plate to compact the ground.

[0003] The hydraulic vibratory compactor for building construction disclosed in Chinese utility model patent application CN212223836U, although it can improve work efficiency and avoid impacting other machinery and causing damage, only adjusts the stroke of the hydraulic cylinder during use, which has little impact on improving efficiency, and thus has a relatively small improvement in compaction efficiency.

[0004] Based on this, this solution proposes a mobile hydraulic plate vibratory compactor. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile hydraulic plate vibratory compactor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile hydraulic plate vibratory compactor, including a mounting box,

[0007] The bottom of the mounting box is open and fixed blocks are fixedly installed on both sides of the mounting box. Two universal wheels are rotatably installed on the bottom of each of the two fixed blocks. Two telescopic rods and an electric telescopic rod are fixedly installed on the top inner wall of the mounting box. The same movable box is fixedly installed at the bottom of the two telescopic rods. The output shaft of the electric telescopic rod is fixedly connected to the movable box.

[0008] The bottom of the mobile box has two through holes, and two round rods are rotatably installed inside the mobile box. Vertical rods are movably installed in both through holes. The bottom ends of the two vertical rods are fixedly installed with the same compaction plate. A first bevel tooth and a connecting rod are fixedly sleeved on both round rods. A swing rod is rotatably installed on both vertical rods. A sliding hole is opened on both swing rods, and a rotating rod is fixedly sleeved on both swing rods. Both rotating rods are rotatably installed on one side inner wall of the mobile box. A sliding block is slidably installed in both sliding holes. A rotating shaft is rotatably installed between the two sliding blocks and the corresponding connecting rods.

[0009] A dual-axis motor is fixedly installed inside the mobile box. Each of the two output shafts of the dual-axis motor is fitted with a second bevel gear, and the two second bevel gears mesh with the corresponding first bevel gears.

[0010] Preferably, each of the two telescopic rods is fitted with a buffer spring, with one end of the two buffer springs fixed to the corresponding telescopic rod and the other end fixed to the movable box.

[0011] By adopting the above technical solution, the reaction force of the electric telescopic pole is reduced by using two buffer springs.

[0012] Preferably, push rods are fixedly installed on both sides of the mounting box.

[0013] By adopting the above technical solution, the entire device can be easily moved using a push rod.

[0014] Preferably, the top of each of the two fixing blocks is threaded with a locking bolt, the bottom of each of the two locking bolts is fixedly sleeved with a brake plate, and the top of each of the two locking bolts is fixedly sleeved with a crank handle.

[0015] By using the above technical solution, rotating the two cranks downwards will cause the two locking bolts to be screwed downwards, which will push the two brake plates downwards, so that the two brake plates come into contact with the ground, thus braking and fixing the entire device.

[0016] Preferably, a return spring is fitted onto each of the two vertical rods, with one end of the two return springs fixed to the corresponding vertical rod and the other end fixed to the inner wall of the corresponding through hole.

[0017] By adopting the above technical solution, the return spring facilitates the reset of the vertical rod.

[0018] Preferably, the front end of the mounting box is provided with a transparent observation window.

[0019] The above technical solution allows for easy observation of the internal condition of the installation box through a transparent viewing window.

[0020] Preferably, the two swing arms are arranged symmetrically at an angle.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By first moving the device to a suitable position, and then turning the two cranks downwards, the two locking bolts will be screwed downwards, which will push the two brake plates downwards, so that the two brake plates come into contact with the ground, thus braking and fixing the entire device, which facilitates the movement of the entire device.

[0023] 2. By starting the dual-axis motor, the two second bevel teeth rotate, which in turn rotate the two first bevel teeth, thus driving the rotation of the two connecting rods. The two connecting rods then cause the two sliding blocks to slide back and forth in their corresponding sliding holes, which in turn causes the two swing rods to swing back and forth around their corresponding rotating rods as fulcrums. This causes the two vertical rods to move up and down reciprocally, which in turn causes the compaction plate to move up and down reciprocally. This allows for repeated impact compaction of the surface, resulting in high compaction efficiency. The compaction depth can be adjusted by starting the electric telescopic rod and adjusting the descent distance of the compaction plate. Two buffer springs reduce the reaction force of the electric telescopic rod. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-3This utility model provides a technical solution: a mobile hydraulic plate vibratory rammer, including a mounting box 1. A transparent observation window 2 is provided at the front end of the mounting box 1. The bottom of the mounting box 1 is open, and fixing blocks 4 are fixedly installed on both sides of the mounting box 1. Two universal wheels 3 are rotatably installed on the bottom of each of the two fixing blocks 4. Two telescopic rods 10 and an electric telescopic rod 9 are fixedly installed on the inner wall of the top of the mounting box 1. The bottom of the two telescopic rods 10 is fixedly installed with the same movable box 15. The output shaft of the electric telescopic rod 9 is fixedly connected to the movable box 15. Two through holes are opened at the bottom of the movable box 15, and two round rods 18 are rotatably installed inside the movable box 15. Vertical rods 13 are movably installed in each of the two through holes. The bottom of the two vertical rods 13 is fixedly installed with the same compaction plate 14. Return springs 12 are sleeved on each of the two vertical rods 13. One end of each return spring 12 is fixed to the corresponding vertical rod 13, and the other end is fixed to the inner wall of the corresponding through hole. First conical teeth 19 are fixedly sleeved on each of the two round rods 18. A swing rod 23 is rotatably mounted on each of the two vertical rods 13, connected to the connecting rod 17. The two swing rods 23 are symmetrically arranged at an angle. Each swing rod 23 has a sliding hole 22, and a rotating rod 21 is fixedly sleeved on each swing rod 23. The two rotating rods 21 are rotatably mounted on the inner wall of one side of the moving box 15. A sliding block 24 is slidably mounted in each of the two sliding holes 22. A rotating shaft 25 is rotatably mounted between each sliding block 24 and its corresponding connecting rod 17. A double shaft is fixedly mounted inside the moving box 15. The motor 16, a dual-axis motor, has two output shafts each fixedly fitted with a second bevel gear 20. The two second bevel gears 20 mesh with the corresponding first bevel gears 19. With the above structure, by starting the dual-axis motor 16, the two vertical rods 13 are driven to move up and down reciprocally, which in turn drives the compaction plate 14 to move up and down reciprocally, thus performing back-and-forth tamping on the surface. The tamping efficiency is high. By starting the electric telescopic rod 9, the descent distance of the compaction plate 14 can be adjusted, thereby adjusting the tamping depth.

[0030] Combination Figure 1-2 As shown, each of the two telescopic rods 10 is fitted with a buffer spring 11. One end of the two buffer springs 11 is fixed to the corresponding telescopic rod 10, and the other end is fixed to the movable box 15. Through the above structural arrangement, the reaction force of the electric telescopic rod 9 is reduced by the two buffer springs 11, thereby increasing the stability of the device.

[0031] Combination Figure 1-2As shown, push rods 8 are fixedly installed on both sides of the mounting box 1, and locking bolts 6 are threadedly installed on the top of the two fixing blocks 4. Brake plates 5 are fixedly sleeved at the bottom of the two locking bolts 6, and crank handles 7 are fixedly sleeved at the top of the two locking bolts 6. With the above structure, the entire device can be easily pushed by the push rods 8 and the universal wheels 3. By first moving the device to a suitable position, and then turning the two crank handles 7 downward, the two locking bolts 6 can be driven to rotate downward, which can push the two brake plates 5 downward, so that the two brake plates 5 come into contact with the ground, thus braking and fixing the entire device.

[0032] The working principle of this utility model is as follows: First, move the device to a suitable position. Then, by rotating the two cranks 7 downwards, the two locking bolts 6 are screwed downwards, which pushes the two brake plates 5 downwards, causing them to contact the ground and thus braking and fixing the entire device. Next, by activating the electric telescopic rod 9, the moving box 15 is moved downwards, which in turn moves the compaction plate 14 downwards. Then, by activating the dual-axis motor 16, the two second bevel teeth 20 are rotated, which in turn drive the two first bevel teeth 19 to rotate. This drives the rotation of the two connecting rods 17, which in turn causes the two sliding blocks 24 to slide back and forth within their corresponding sliding holes 22. This, in turn, causes the two swinging rods 23 to swing back and forth around their corresponding rotating rods 21, thus driving the two vertical rods 13 to move up and down reciprocally. This, in turn, causes the compaction plate 14 to move up and down reciprocally, allowing for repeated impact compaction of the surface. The compaction efficiency is high. The compaction depth can be adjusted by activating the electric telescopic rod 9 to change the descent distance of the compaction plate 14. Two buffer springs 11 reduce the reaction force of the electric telescopic rod 9. This invention features a simple structure and is easy to use. The mobile hydraulic plate vibratory rammer described above utilizes a reciprocating vibration structure to increase compaction efficiency and facilitate improved construction efficiency.
