Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering construction machinery, in particular to a mechanical device for ground compaction, and more particularly to an intelligent ground rammer suitable for narrow or restricted spaces, and having the functions of ground compaction, stone crushing, polishing and polishing integrated. BACKGROUND

[0002] In the current transition from "incremental expansion" to "stock upgrading" in the construction industry, ground construction in narrow areas such as building gaps and pipe gallery trenches faces significant challenges. Large road rollers have a 30-40% visual and operational blind area in such spaces, poor flexibility, and produce 100-120 decibel strong noise, poor adaptability and significant safety hazards. Common small compaction equipment has poor compaction uniformity due to weak excitation force, which can easily cause ground subsidence and pavement cracking, and its operating efficiency in narrow scenes may be only one-third of that in open spaces, with labor costs accounting for more than 40%. In addition, existing equipment is prone to "jumping" under continuous vibration load, has serious component wear, and relies heavily on high-skilled operators, which is increasingly difficult to meet the current construction requirements for quality, efficiency and safety.

[0003] In the face of the growing building maintenance market and the increasing demand for green, safe and high-quality construction in the industry, the market urgently needs a comprehensive solution that can systematically address the above challenges. In the technical field of engineering construction machinery, the market urgently needs a new multifunctional intelligent ground rammer that can balance the operating capacity of medium-sized equipment and the flexibility of small-sized equipment, has reliable damping and mechanical structure to suppress "jumping", ensure compaction uniformity and stability, integrates intelligent remote control function to reduce safety risks and labor dependence, and has good functional expansion capability to flexibly meet the construction needs of diversified narrow scenes.

[0017] The double-cylinder precision steering device is controlled by an infrared remote controller. The electric control unit drives hydraulic pump motor one and hydraulic pump motor two to control two independent oil chambers of the cross cylinder. The oil pressure sensor one and the oil pressure sensor two feed back the system pressure in real time to realize servo control. The hydraulic oil drives the piston one and the piston two to drive the cross-cylinder piston rod one and the cross-cylinder piston rod two to extend and retract. Then, through the symmetric plane linkage mechanism composed of steering connecting rods one, two, three and four, the cross-cylinder connecting rod one and the cross-cylinder connecting rod two are driven to rotate around the shaft one and the shaft two. Finally, through the shaft coupling one, the shaft coupling two, the wheel hub flange one and the wheel hub flange two, the steering angles and torques of the wheels one and two are accurately controlled. The steering shaft sleeves one, two, three and four are respectively installed at the upper and lower ends of the shaft one and the shaft two, and are connected with the cross plates one and two to form a four-point supporting structure, which effectively enhances the rigidity and stability of the steering system. When the four-bar quick-return ramming device works, the YEJ series B3 type electromagnetic brake three-phase asynchronous motor is started to drive the synchronous pulley one. The power is transmitted to the synchronous pulley two through the belt one to drive the spiral gear steering gear. The power is transmitted to the synchronous pulley four through the belt two to drive the spiral gear steering gear. The power is transmitted to the synchronous pulley three through the gearbox rod to drive the synchronous pulley four. Finally, the ratchet tooth connecting rod is driven to rotate. The ratchet tooth connecting rod is supported to rotate through the double-row angular contact ball bearings one and two with dust covers at both ends to drive the quick-return four-bar mechanism composed of the connecting rod one, the connecting rod two, the connecting rod three and the piston hook connecting rod to move, so that the rammer realizes the ramming action of lifting and accelerating falling. The fixed sleeve realizes the switching between the working state and the walking state by lifting the piston rod of the standard hydraulic cylinder. The rammer is connected with the piston hook connecting rod through the piston hook fixing piece and linearly slides in the fixed sleeve to complete the continuous and uniform compaction of the ground. When the manually adjustable motor-screw drill bit breaking device works, the operator rotates the hand wheels one and two to drive the vertical ball screw and the horizontal ball screw, respectively, to drive the cross slide to move vertically and horizontally on the vertical linear guide and the horizontal linear guide to realize the coarse positioning of the drilling power head in the XY plane. The position can be locked through the locking handles one and two. The drill arms one and two constitute a four-bar linkage mechanism through the drill arm connecting rod. The pitch angle of the drill arm two can be adjusted steplessly by moving the posture adjusting slider. The power head mounting slides one and two can be finely adjusted on the drill table guide to finally accurately position the drilling power head to the target point for drilling or breaking operation. The positioning process of the modular quick-change manual precision polishing device is similar to that of the breaking device. The motor mounting slides one and two are accurately positioned in the XY plane through two groups of orthogonal ball screw pairs, and the pitch angle of the drill arm two is adjusted steplessly through the four-bar linkage mechanism. The output shaft of the three-phase alternating current induction motor is a standard interface, which can quickly replace the hob shaft (install the pre-razor gear hob) or the grinding wheel shaft (install the double-bevel grinding wheel). The workpiece surface is polished, polished or deburred through the structure of the grinding wheel locking flange or the tooth cutting knife anti-drop plate. The large shock absorbing springs one, two and three directly bear the main load on the upper part of the equipment and provide basic damping.The medium shock-absorbing springs 1-4 are arranged on the upper part of the steering system, isolate and absorb high-frequency impact from the rammer; the medium shock-absorbing springs 5-8 are arranged on the tail part of the equipment, attenuate the tail part shaking and swinging during operation; the viscous dampers 1-4 are evenly connected between the shell and the chassis, when the equipment occurs lateral vibration, the viscous fluid in the damper generates damping force, dissipates vibration energy, effectively suppresses lateral swinging, and improves the stability of the whole machine; the Y series three-phase asynchronous motor is started when the remote control belt drive differential assembly works, belt transmission is formed through the belt pulley 1, the belt 3 and the belt pulley 2, power transmission and one-stage speed reduction are realized; the power is transmitted to the driving gear through the universal joint transmission shaft composed of the transmission shaft 1, the cross shaft 1 and the transmission shaft 2; the driving gear drives the driven gear, and two-stage speed reduction is realized; the planet gears 1 and 2 in the differential distribute the power to the side gears 1 and 2, and transmit the power to the hub flanges 1 and 2 through the half shafts 1 and 2, finally drive the wheels 3 and 4 to rotate, and realize the differential function when turning, and guarantee the driving stability; the towing device is sequentially connected through the tow hook, the first universal joint, the cross shaft 2, the second universal joint and the tow ball and the channel steel base; the universal joint and the ball hinge combined structure can absorb relative motion and impact in multiple directions, realize safe and flexible equipment traction; the multifunctional intelligent ramming machine can realize differential steering through remote control starting of the rear wheel driving assembly when moving and changing the scene, and the front wheel steering device can be accurately deflected under the electric-hydraulic servo control, so that the flexible maneuvering of the equipment in the narrow space is guaranteed; when the ramming operation is performed, the motor of the ramming mechanism drives the four-bar mechanism with quick-return characteristics through multi-stage synchronous belt transmission and gear steering, so that the rammer realizes lifting and accelerated falling, and generates continuous and uniform impact compaction effect; when the crushing or polishing operation is performed, the three-dimensional accurate positioning of the drilling power head or the quick-change polishing tool can be realized through the manual precise positioning platform, and multifunctional fine processing is realized; the damping system composed of the composite spring and the viscous damper arranged in the partition continuously works during the whole machine operation, and effectively suppresses various vibrations and impacts; in addition, the equipment can realize safe traction through the towing device combined with the universal joint and the ball hinge; in summary, the walking, steering, ground ramming, stone crushing, polishing and damping functions are integrated in the multifunctional intelligent ramming machine, and efficient, stable and multifunctional operation in a narrow and complex environment is realized.

[0018] In summary, the whole structure of the multifunctional intelligent ramming machine is reasonable, the operation is convenient, the complex working conditions can be well coped with, and the problems of low operation efficiency and inability to effectively perform work due to limited space are solved. The equipment has good maneuverability and multifunctional operation ability in a narrow space.

6. A novel multi-functional intelligent soil compactor according to claim 1, characterized in that, The central support composite shock absorber includes: large shock absorber spring 1, large shock absorber spring 2, large shock absorber spring 3, medium shock absorber spring 1, medium shock absorber spring 2, medium shock absorber spring 3, medium shock absorber spring 4, medium shock absorber spring 5, medium shock absorber spring 6, medium shock absorber spring 7, medium shock absorber spring 8, viscous damper 1, viscous damper 2, viscous damper 3, and viscous damper 4. Large shock absorber springs 1, 2, and 3 are directly mounted on the suspension plate, forming the core load-bearing and main vibration damping unit of the system. This group of springs has the highest stiffness and load-bearing capacity in the system. Its core function is to directly bear and support most of the static and dynamic loads from the upper structure of the equipment, and to provide the most basic vertical vibration damping for the entire machine. Medium shock absorber springs 1, 2, 3, and 4 are arranged between the upper part of the chassis lateral steering cylinder and the lower part of the housing, forming an elastic isolation layer. Its core function is to reduce the impact force transmitted to the steering system through the housing when the ram is working. Through its elastic support, this spring group can effectively isolate and absorb the high-frequency, high-amplitude impact load from the ram impacting the ground, thereby directly protecting the precision hydraulic components and transmission mechanism in the steering system and preventing damage due to overload impact. Medium shock absorber springs 5, 6, 7, and 8 are arranged in parallel at the rear of the chassis. This group of springs is specifically designed for the rear of the equipment, which is prone to generating shocks during operation. The design optimizes the vertical and longitudinal swaying of the engine. Through the coordinated action of four springs, it effectively attenuates the vertical and longitudinal vibrations at the rear, improving the stability and grounding of the rear section of the engine during dynamic operation. Viscous dampers one, two, three, and four are evenly distributed, with the front end connected to the outer shell and the rear end connected to the chassis gear axle and suspension plate. This hinged connection ensures that the dampers can move freely without motion interference when the chassis and suspension plate undergo relative lateral displacement. This damper group does not provide primary support stiffness; its core function is based on the viscous damping effect. When the chassis vibrates laterally relative to the suspension plate, the piston inside the damper forces viscous fluid through the throttling orifice, thereby generating a damping force proportional to the vibration velocity. This force effectively suppresses lateral vibration, rapidly reducing the amplitude and duration of vibration by dissipating vibration energy, thus significantly reducing the potential fatigue damage and instability risk to the main structure caused by excessive lateral sway.

7. A novel multi-functional intelligent soil compactor according to claim 1, characterized in that, The remote-controlled belt-driven differential assembly includes: wheel three, wheel four, bolt twenty-five, bolt twenty-six, bolt twenty-seven, bolt twenty-eight, bolt twenty-nine, bolt thirty, bolt thirty-one, bolt thirty-two, bolt thirty-three, bolt thirty-four, nut twenty-one, nut twenty-two, nut twenty-three, nut twenty-four, nut twenty-five, nut twenty-six, nut twenty-seven, nut twenty-eight, nut twenty-nine, nut thirty, hub flange one, hub flange two, half shaft one, half shaft two, side gear one, side gear two, planetary gear one, planetary gear two, driven gear (ring gear), driving gear, drive shaft one (with universal joint fork), drive shaft two (with universal joint fork), cross-shaped element one, bearing, pulley one, pulley two, belt three, and Y-series three-phase asynchronous motor. The output shaft of the Y-series three-phase asynchronous motor is fixed to pulley one via a flat key, achieving initial torque transmission. Pulley one, through belt three and pulley two, forms a belt drive system to complete power transmission and first-stage reduction. Simultaneously, the buffering characteristics of belt drive improve the smoothness of power output in remote control scenarios. Pulley two is connected to the input end of driveshaft one (with universal joint fork) via a flat key. The universal joint fork of driveshaft one and driveshaft two (with universal joint fork) form a cross-shaped universal joint via a cross-shaped connector. This structure can compensate for installation errors and dynamic deformation of the frame, achieving reliable power transmission between non-collinear shafts and adapting to the compact layout requirements of remote control equipment. The output end of driveshaft two is connected to the drive gear, inputting power into the differential assembly. The drive gear and driven gear (ring gear) form the main reducer gear pair, achieving second-stage reduction and torque amplification to meet the high torque requirements of remote control equipment. The driven gear is bolted to the differential protective housing and supported by bearings on the axle housing. Planetary gears one and two are mounted on the planetary gear shaft inside the differential housing through the central shaft hole. They can rotate around their own axis and revolve with the driven gear. The planetary gears simultaneously mesh with side gears one and two to achieve differential function (to adapt to the speed difference when the remote-controlled wheels turn). The inner holes of side gears one and two are machined with internal splines. One end of half-shafts one and two are connected to the internal splines of the side gears through external splines, which not only transmits power but also allows for slight slippage (to adapt to the slight displacement of the shaft system during differential). The other end of half-shafts one and two are connected to hub flanges one and two through splines to reliably transmit power. Wheel three is fastened to hub flange one with bolts twenty-five, twenty-six, twenty-seven, twenty-eight, and twenty-nine and nuts twenty-one, twenty-two, twenty-three, twenty-four, and twenty-five. Wheel four is fastened to hub flange two with bolts thirty, thirty-one, thirty-two, thirty-three, and thirty-four and nuts twenty-six, twenty-seven, twenty-eight, twenty-nine, and thirty, ensuring the connection strength of the wheel ends and the convenience of disassembly and assembly.

The second universal joint is hinged to the triangular support of the channel steel via the towing ball, thus forming a force transmission chain that allows for multi-directional swing. The towing force is transmitted to the channel steel base via the tow hook and universal joint mechanism. The combination design of the universal joint and ball joint effectively absorbs relative motion in all directions.
