Description

Technical Field

[0001] The present invention relates to the technical field of road construction, and in particular to a ramming device suitable for road construction in complex road conditions. Background Art

[0002] In modern transportation infrastructure construction, road construction is a key link. With the acceleration of urbanization and the increase in the development intensity of remote areas, more and more road construction projects need to be carried out in complex road conditions, such as special terrain areas like mountains, hills, wetlands, and narrow streets in old urban areas. These complex road conditions bring many challenges to road construction, and obvious limitations are exposed by traditional road construction ramming devices in these scenarios.

[0003] In mountainous and hilly areas, the terrain has large undulations and complex slope changes. Due to the limitations of its own structure and stability design, traditional ramming devices are difficult to operate effectively on inclined or uneven ground. It is difficult to adjust its center of gravity, and it is prone to rollover during movement, which not only affects the construction progress but also poses a threat to the lives and safety of construction workers. Moreover, the geological conditions in these areas are complex, and there may be different geological structures such as rocks and soft soil layers. The ramming methods of traditional ramming devices cannot meet the different requirements of different geological conditions for ramming force and depth, resulting in poor ramming effects and affecting the stability of the road foundation. In soft ground areas such as wetlands, the soil has a high water content and low bearing capacity. When ordinary ramming devices are operating, the equipment is prone to sink, and its walking system and support structure are difficult to play their normal roles. This not only increases the difficulty of equipment movement but also may cause equipment damage. At the same time, due to the inability to compact the ground stably, it is difficult to meet the specified density standard and cannot ensure the durability and safety of the road during subsequent use. In space-limited areas such as narrow streets in old urban areas, the construction site is narrow, and large traditional ramming equipment is difficult to operate. Its large volume and complex operation requirements make the turning and movement of the equipment extremely inconvenient in a limited space, and it may even be unable to enter some construction areas.

[0031] Embodiment

[0032] Referring to Figure 1-6 , an embodiment of the present invention provides a ramming device suitable for road construction in complex road conditions. This device includes

[0033] A support assembly 100, including a base 101, a support plate 102 fixedly connected to the upper end of the base 101, a bracket 103 bolted to the side wall of the support plate 102, and a liquid storage tank 104 fixedly connected to the end of the support plate 102. The end of the bracket 103 is bolted to the side wall of the liquid storage tank 104;

[0034] The tamping assembly 200 includes a diesel engine 201 fixedly connected to the middle position of the support plate 102, a support base 202 fixedly connected to the side wall of the base 101, an eccentric roller 203 rotatably installed in the middle of the support base 202, and a pulley 204 adapted to be installed on the output shaft of the diesel engine 201 and the end of the eccentric roller 203. The side walls of the two sets of pulleys 204 are connected by a belt 205.

[0035] Among them, the support assembly 100 serves as the basic structure of the entire device and plays a supporting and auxiliary role. The base 101 is used to effectively prevent soil and stone splashing during the compaction process to ensure the safety of construction personnel and surrounding equipment. The bracket 103 is connected to the side wall of the support plate 102 by bolts, and the end is also connected to the side wall of the liquid storage tank 104 by bolts, which plays the role of connecting and supporting the liquid storage tank 104. The liquid storage tank 104 is fixedly connected to the end of the support plate 102, the bottom is clamped on the upper end of the sleeve 206, and the end extends to the outside of the base 101. The liquid storage tank 104 is used to store liquids required during the construction process, such as lubricating oil, coolant, etc., to provide guarantee for the stable operation of the device. Its position design is reasonable, which is convenient for adding liquid and will not affect the normal operation of other components of the device. At the same time, it can add counterweight to the device and improve the compaction effect. The compaction assembly 200 undertakes the core compaction work, and multiple components work together to achieve efficient compaction. The diesel engine 201 is fixedly connected to the middle position of the support plate 102, and provides power for the entire compaction assembly as a power source. The diesel engine 201 has the characteristics of strong power and strong adaptability, and can meet the construction needs under complex road conditions. The support seat 202 is fixedly connected to the side wall of the base 101, providing a stable support and rotation basis for the eccentric roller 203. The eccentric roller 203 is rotatably installed in the middle of the support seat 202, and is a key component for realizing the compaction function. The eccentric roller 203 rotates at a high speed under the drive of the diesel engine, and uses the centrifugal force generated by its eccentric structure to achieve the compaction effect on the ground. Pulley 204 and belt 205 The output shaft of the diesel engine 201 and the end of the eccentric roller 203 are adapted to be installed with a pulley 204, and the side walls of the two sets of pulleys 204 are connected by a belt 205 transmission. This transmission method can stably transmit the power of the diesel engine to the eccentric roller 203, and has a certain buffering effect, which can reduce the vibration and impact of the equipment during operation.

[0036] Specifically, the tamping assembly 200 further includes a sleeve 206 fixedly connected to the side wall of the base 101 . The sleeve 206 is sleeved on the outside of the eccentric roller 203 , and a bearing used in conjunction with the eccentric roller 203 is fixedly connected inside the sleeve 206 .

[0037] Among them, a sleeve 206 is sleeved on the outside of the eccentric roller 203, and a bearing used in conjunction with the eccentric roller 203 is fixedly connected inside the sleeve 206. The setting of the bearing can reduce the friction when the eccentric roller rotates, improve the transmission efficiency, and ensure the stable rotation of the eccentric roller.

[0038] Furthermore, the ramming component 200 further includes a positioning plate 207 fixedly connected to the side wall of the support plate 102, and a guide wheel 208 rotatably mounted at the end of the positioning plate 207. The side wall of the guide wheel 208 is in rolling contact with the side wall of the belt 205.

[0039] Among them, the positioning plate 207 is fixedly connected to the side wall of the support plate 102 of the guide wheel 208. The positioning plate 207 is rotatably mounted with the guide wheel 208 at its end. The side wall of the guide wheel 208 is in rolling contact with the side wall of the belt 205. The function of the guide wheel 208 is to position and guide the belt 205, prevent the belt from shifting, slipping, etc. during the transmission process, and ensure the stability and reliability of power transmission.

[0040] Even further, the ramming component 200 further includes a cover plate 209 fixedly connected to the side wall of the support base 202, and the cover plate 209 is snap-fitted outside the pulley 204.

[0041] Among them, the cover plate 209 is fixedly connected to the side wall of the support base 202 and is snap-fitted outside the pulley 204. The cover plate can effectively prevent sundries from entering between the pulley and the belt, avoid equipment failures caused by sundries entanglement, and at the same time can play a certain protective role to ensure the safety of construction workers.

[0042] Preferably, the bottom of the liquid storage tank 104 is snap-fitted to the upper end of the sleeve 206, and the end of the liquid storage tank 104 extends to the outside of the base 101. The end of the base 101 is provided with a bent edge structure, and the bent edge at the end of the base 101 is bent in front of the support base 202.

[0043] Among them, the end of the base 101 is specially designed with a bent edge structure, and the bent edge is bent in front of the support base 202. This design not only enhances the structural strength of the base 101, but also can effectively block the splashing of soil and stone during the ramming process, ensuring the safety of construction workers and surrounding equipment.

[0044] It should be noted that the support component 100 further includes a backing plate 105 snap-fitted to the bottom of the base 101, and the upper end of the backing plate 105 is connected to the side wall of the base 101 by bolts.

[0045] Among them, the bottom of the base 101 is snap-fitted with a backing plate 105 and fixed by bolts. The backing plate 105 can increase the contact area between the base and the ground, disperse the weight of the device, prevent the base from sinking during construction on soft ground, and improve the stability of the device.

[0046] Preferably, the support component 100 further includes a handrail 106 hinged to the side wall of the support plate 102. The side wall of the handrail 106 is snap-fitted to the side wall of the bracket 103, and a switch cooperating with the diesel engine 201 is installed on the side wall of the handrail 106.

[0047] Among them, the support plate 102 is vertically and fixedly connected to the upper end of the base 101, providing a stable installation platform for other components. An armrest 106 is hinged to its side wall. The armrest 106 can be flexibly adjusted according to the operation requirements of construction workers. A switch used in conjunction with the diesel engine 201 is installed on the armrest 106, facilitating the construction workers to control the start and stop of the equipment at any time. At the same time, the side wall of the armrest 106 is clamped to the side wall of the bracket 103, further enhancing the stability of the overall structure.

[0048] Preferably, the support assembly 100 further includes a support pipe 107 hinged to the side wall of the bracket 103, a connecting rod 108 rotatably installed at the end of the support pipe 107, and an auxiliary wheel 109 rotatably installed at the end of the connecting rod 108. The auxiliary wheel 109 is used in conjunction with the backing plate 105. A pull rod 110 is clamped at the end of the support pipe 107, and the upper end of the pull rod 110 is clamped to the side wall of the bracket 103.

[0049] Among them, a support pipe 107 is hinged to the side wall of the bracket 103. A connecting rod 108 is rotatably installed at the end of the support pipe 107, and an auxiliary wheel 109 is rotatably installed at the end of the connecting rod 108. The auxiliary wheel 109 is used in conjunction with the backing plate 105. During the movement of the device, the auxiliary wheel 109 can assist the device to move on complex terrains, reduce the friction between the base and the ground, facilitate the construction workers to push the equipment, and can adaptively adjust the height according to the terrain changes to ensure that the device always remains stable. A pull rod 110 is clamped at the end of the support pipe 107, and the upper end of the pull rod 110 is clamped to the side wall of the bracket 103, which plays a role in restricting the rotation angle of the support pipe 107 and ensuring that the auxiliary wheel 109 functions in a proper position.

[0050] During use, during construction, the construction workers first adjust the position of the auxiliary wheel 109 according to the terrain conditions. By adjusting the angle of the support pipe 107, the auxiliary wheel 109 is made to be in good contact with the ground, ensuring the stability of the device under complex road conditions. Then, the construction workers hold the handrail 106 and press the switch on the handrail to start the diesel engine 201. The diesel engine 201 starts to operate, and the output shaft drives the pulley 204 on it to rotate. Through the transmission of the belt 205, the pulley 204 at the end of the eccentric roller 203 also rotates accordingly, and then drives the eccentric roller 203 to rotate at a high speed. During the rotation of the eccentric roller 203, due to its eccentric structure, a centrifugal force will be generated, and this centrifugal force causes the device to produce a tamping action of up and down vibration. When the eccentric roller 203 rotates, the guide wheel 208 positions and guides the belt 205 to ensure the stability of the belt drive; the cover plate 209 prevents sundries from entering between the pulley and the belt, ensuring the normal operation of the equipment. The liquid in the liquid storage tank 104 provides lubrication and cooling for components such as the diesel engine 201 and bearings through the corresponding pipeline system during the operation of the equipment, ensuring the stable operation of the equipment. During the tamping process, the bent edge of the base 101 blocks the splashing of soil and stones, and the cushion plate 105 increases the contact area with the ground, improving the stability of the device. The construction workers push the handrail 106 to drive the device to move in the construction area, realizing the comprehensive tamping operation of the road surface under complex road conditions.

[0051] In summary, the unique design of the support components, such as the auxiliary wheel 109, the cushion plate 105, etc., enables the device to operate stably under a variety of complex road conditions, including soft ground, rough terrain, etc., expanding the applicable range of the equipment. The efficient tamping effect of the eccentric roller 203, combined with a stable power transmission system, can tamp the road surface deeply and evenly, effectively improving the density and stability of the road surface, and ensuring the quality of road construction. The bent edge structure of the base, the reasonable connection method between components, and the synergistic effect of components such as the auxiliary wheel enhance the stability of the device during operation, reduce equipment shaking and displacement, lower the operation difficulty of construction workers, and improve construction safety. The setting of the cover plate 209 can effectively prevent sundries from entering key components, reducing equipment failures; the reasonable layout of the liquid storage tank facilitates the addition of liquid, and the connection method between components is convenient for disassembly and maintenance, reducing the maintenance cost and maintenance difficulty of the equipment. The integrated switch on the handrail 106 is convenient for construction workers to control the start and stop of the equipment; the overall structure design conforms to ergonomics, facilitating the pushing and operation of construction workers, and improving construction efficiency.
