It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0027] As Figures 1-7 shown, the present utility model provides a ramming device for highway engineering construction, including: a device body 1 and a connecting head 2, and an installation mechanism 3 is arranged on the device body 1;

[0028] The installation mechanism 3 includes a fixing plate 301. Two groove blocks 302 are fixed on the front surface of the fixing plate 301. Cylindrical holes 303 are formed on both sides of the inner wall of each groove block 302. A collar block 304 is fixedly sleeved inside each cylindrical hole 303. The four collar blocks 304 are divided into two groups. A T-shaped block 305 is movably sleeved between the inner parts of each group of collar blocks 304. A perforated block 306 is movably sleeved at the opposite end of each of the two T-shaped blocks 305. A spring 308 is installed at the bottom of each perforated block 306. A plug rod 307 is movably sleeved inside each spring 308. The rear surface of the fixing plate 301 is fixed to the installation end of the device body 1. The two connection ends of the connector 2 are respectively movably sleeved inside the two groove blocks 302. The opposite ends of the two T-shaped blocks 305 are respectively movably sleeved inside the through holes at the two connection ends of the connector 2. The surfaces of the two T-shaped blocks 305 are respectively in contact with the opposite sides of the two groove blocks 302. The opposite sides of the two perforated blocks 306 are respectively in contact with the opposite sides of the two groove blocks 302. The top ends of the two plug rods 307 respectively movably penetrate through the bottoms of the two perforated blocks 306. The top ends of the two plug rods 307 respectively movably penetrate through the top inner walls of the two perforated blocks 306. The top ends of the two plug rods 307 respectively movably penetrate through the lower sides of the two T-shaped blocks 305. The upper sides of the two plug rods 307 are respectively slidably embedded in the bottoms of the two groove blocks 302. The upper sides of the two plug rods 307 are respectively installed with the bottom ends of the two springs 308. Four auxiliary blocks 4 are fixed on both sides of each groove block 302. Protective shells 5 are arranged on the opposite sides of the two groove blocks 302. Four hand-tightening bolts 6 are respectively threadedly penetrated through the surfaces of each protective shell 5. One side of each auxiliary block 4 close to the device body 1 is fixed to the front surface of the fixing plate 301. The tops of the two protective shells 5 are respectively in contact with the bottoms of the two perforated blocks 306. The two springs 308 are respectively inside the two protective shells 5. The eight hand-tightening bolts 6 are divided into two groups. The threaded ends of the two groups of hand-tightening bolts 6 are respectively threadedly connected to the opposite sides of the two groove blocks 302.

[0029] The achieved effect is that when it is necessary to disassemble the device body 1 from the connector 2, first loosen both sets of hand-tightening bolts 6 at this time, then remove both protective shells 5, and then apply a force to each of the two insertion rods 307 so that both insertion rods 307 move vertically downward. At this time, both vertically moving insertion rods 307 will, under the action of the corresponding perforated blocks 306, cause the corresponding springs 308 to undergo elastic deformation. At the same time, both vertically moving insertion rods 307 will separate from the corresponding groove blocks 302. When both insertion rods 307 can no longer move, first stop the movement of the two insertion rods 307. At this time, the tops of both insertion rods 307 will separate from the corresponding T-shaped blocks 305. Then apply a force to each of the two perforated blocks 306 so that both perforated blocks 306 move away from each other until both perforated blocks 306 separate from the corresponding T-shaped blocks 305. At this time, both moving perforated blocks 306 will, with the cooperation of the corresponding springs 308, drive the corresponding insertion rods 307 to move together. Then release the force applied to the two insertion rods 307. At this time, both insertion rods 307 will, under the action of the resilience of the corresponding springs 308, perform a reset movement until both insertion rods 307 are reset to their original positions. After that, move both perforated blocks 306 away, and then apply a force to each of the two T-shaped blocks 305 so that the two T-shaped blocks 305 move towards each other until both T-shaped blocks 305 move out from between the interiors of the corresponding set of collar blocks 304. At this time, both T-shaped blocks 305 will separate from the connection ends of the corresponding connector 2. Then move both connection ends of the connector 2 out from the interiors of the corresponding groove blocks 302, and the operation of disassembling the device body 1 from the connector 2 is completed. When it is necessary to install the device body 1 on the connector 2, just perform the above operation steps in reverse.

[0030] Working principle: When it is necessary to disassemble the device body 1 from the connector 2, first loosen both sets of hand-tightening bolts 6 at this time, then remove both protective shells 5, and then apply a force to each of the two insertion rods 307, so that both insertion rods 307 move vertically downward. At this time, both vertically downward moving insertion rods 307 will, under the action of the corresponding perforated blocks 306, cause the corresponding springs 308 to undergo elastic deformation. At the same time, both vertically downward moving insertion rods 307 will separate from the corresponding groove blocks 302. When both insertion rods 307 can no longer move, stop the movement of both insertion rods 307 at this time. At this time, the tops of both insertion rods 307 will separate from the corresponding T-shaped blocks 305. Then apply a force to each of the two perforated blocks 306, so that both perforated blocks 306 move away from each other until both perforated blocks 306 separate from the corresponding T-shaped blocks 305. At this time, both moving perforated blocks 306 will drive the corresponding insertion rods 307 to move together under the cooperation of the corresponding springs 308. Then release the force applied to the two insertion rods 307. At this time, both insertion rods 307 will move back to their original positions under the action of the resilience of the corresponding springs 308 until both insertion rods 307 return to their original positions. After that, move both perforated blocks 306 away, and then apply a force to each of the two T-shaped blocks 305, so that both T-shaped blocks 305 move towards each other until both T-shaped blocks 305 move out from between the interiors of the corresponding set of collar blocks 304. At this time, both T-shaped blocks 305 will separate from the connection ends of the corresponding connector 2. Then move both connection ends of the connector 2 out from the interiors of the corresponding groove blocks 302, and the operation of disassembling the device body 1 from the connector 2 is completed. When it is necessary to install the device body 1 on the connector 2, just perform the above operation steps in reverse.

[0031] Among them, the connector 2 is the connector of the working arm on the loader.

[0032] Among them, the device body 1 is the ramming device for highway engineering construction. It usually includes the following main components:

[0033] Power system: Usually composed of an engine or a motor, it provides the power source for the ramming device. It also includes a transmission device, such as belt drive and gear drive, etc., to transmit the power to the ramming mechanism.

[0034] Ramming mechanism: This is the core component of the ramming device. It mainly includes a rammer and a ram plate. The rammer is usually made of high-strength steel, has a large weight and impact force, and rams the ground by repeatedly rising and falling. The ram plate is used to expand the ramming area and improve the ramming efficiency. It also includes a lifting device, such as a hydraulic cylinder and a steel wire rope, etc., to lift the rammer to a certain height and then release it to freely fall to generate an impact on the ground.

[0035] Control system: used to control the operating state of the ramming device, and also includes a safety protection device to ensure the safety and reliability of the ramming device during operation.

[0036] Traveling mechanism: enables the ramming device to move within the construction site, facilitating ramming operations at different positions. It also includes a driving device, such as a hydraulic motor and an electric motor, etc., to provide power for the ramming device to travel.

[0037] Its working principle is as follows: When the power system is started, power is transmitted to the lifting device of the ramming mechanism through the transmission device. The lifting device lifts the rammer to a certain height and then releases it, allowing it to fall freely. Under the action of gravity, the rammer accelerates downward, generating a huge impact force on the ground, reducing the gaps between soil particles on the ground, and making the soil more compact. Then, the above process is repeated to continuously ram the ground until the required degree of compaction is reached. During the ramming process, the traveling mechanism can move the ramming device within the construction site to ram different positions of the ground, and the control system can adjust the operating state of the ramming device according to construction needs, such as the ramming frequency and traveling speed, etc., to improve construction efficiency and quality.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
