Description

Technical Field

[0001] The utility model belongs to the technical field of municipal equipment, and particularly relates to a road compacting device for urban roads and traffic engineering. Background Art

[0002] A compactor is a kind of engineering machinery compaction equipment, which squeezes the foundation through the gravity and variable force of the equipment to achieve the purpose of effectively compacting the foundation. Existing compactors are not convenient to turn. Most compactors need to move the entire equipment to turn, and the friction between the lower end contact surface and the ground increases the labor force.

[0003] After searching, the prior art publication number CN112376542A is a foundation compacting device for construction, in which a movable column is movably installed at the bottom end of the fixed column, a limit plate is fixed at the bottom end of the movable column, and a rotating shaft is movably installed at both ends of the limit plate, and a pressure block is movably connected with the rotating shaft, and the pressure block can rotate relative to the rotating shaft. When performing the compacting operation, the rotation of the eccentric wheel can be driven by the motor, and the fixed column can rotate slightly under the drive of the eccentric wheel, and provide pressure to drive the pressure block to move between the pressure block and the ground. When the pressure block is in contact with the movable column, the spring sheet is pressed to drive the pressure block to rotate relative to the rotating shaft, and the bottom of the pressure block is in the shape of an arc, so it can roll slightly relative to the ground to compact the ground. The disadvantage of this design is that the pressure block is connected to the movable column by a spring. When the pressure block hits the ground, the spring sheets on both sides absorb energy, and then the pressure block is inertially impacted to the ground, which greatly reduces the work done by the motor. At the same time, when the movable column moves upward, the pressure block moves upward through inertia and the active connection of the spring sheet, which makes the vibration amplitude of the equipment too large when it is used.

[0004] After searching, it was found that the prior art announcement number is CN211285159U, which is a rammer for traffic engineering construction. The top of the other outer side of the rammer is fixedly connected to a pushing frame. Since the pushing frame is fixedly installed on the rammer, although a moving wheel is set at the lower end, it is not labor-saving to turn the device through the moving wheel in a place with soft ground. Sometimes the moving wheel will be inserted into the soil, which increases the difficulty of turning the rammer and is not conducive to use.

[0005] In combination with the above technical scheme, most of the existing compactors are large and bulky, and it is inconvenient to turn. At the same time, when the compactor motor drives the compacting block, a part of the force generated by the motor is absorbed by the spring. When it is lifted upward, the compacting part will have inertia. Due to the spring connection, the compacting part will continue to move upward, and will be pulled to the maximum distance of the spring sheet through the spring sheet, and then release kinetic energy laterally, making the equipment unstable. The utility model provides a road compacting device for urban roads and traffic engineering, which solves the above problems. Utility Model Content

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1) The utility model reduces the back-and-forth shaking of the equipment during operation by providing a gear assembly, and maintains the stability of the equipment by providing a fan-shaped counterweight block on one side of the crank. Meanwhile, traditional equipment that is not provided with a crank counterweight block will shake back and forth, wasting part of the force generated by the drive motor.

[0019] 2) Since the gear assembly drives the compaction plate to perform compaction operations, the equipment will vibrate back and forth. Therefore, a shock-absorbing assembly is provided at the lower end of the shell. The shock-absorbing assembly cooperates with the handle turning ring at the lower end to reduce unstable conditions such as equipment jumping. An annular plate is provided on the lower end face of the handle turning ring. The annular plate contacts the ground as the compaction plate moves upward, and the ground is compacted to a certain extent to increase work efficiency. At the same time, the annular plate sequentially transmits the impact force received to the upper spring I through the handle turning ring. The spring I absorbs energy, reducing the impact force on the equipment inside the shell and affecting the life of the equipment. At the same time, the damper reduces the frequency of spring I jumping back and forth, increasing the stability of the equipment.

[0020] 3) By setting up a shock-absorbing component, the shock of the device is reduced. At the same time, the hardness of the shock-absorbing component is also crucial for different road surfaces. If the shock absorption is too hard on a hard road, the equipment will bounce too high, which will affect the safety of the workers. If the ground is too soft, the shock absorption of the equipment will be too soft, and the compaction effect of the equipment will be greatly reduced. Therefore, a shock-absorbing adjustment component is set to control the hardness of the shock-absorbing component. The gear ring I and the gear ring II rotate to drive the gear II and gear III on the shock-absorbing component to rotate. Gear II rotates to adjust the spring height to control the preload force. Gear III rotates to control the ejector pin to achieve the damping rebound speed. The hardness of the shock-absorbing component can be adjusted to correspond to different working environments to prevent the compactor from being unusable and requiring a better compactor, which affects the work progress.

[0021] 4) By providing a handle steering ring, the handle assembly makes circular motion on the handle steering ring to cooperate with the staff working in different directions and improve the convenience of work. The helical gear column II provided on the handle assembly drives the gear at the lower end of the helical gear column I to control the locking columns on both sides, which are plugged into the openings of the handle steering ring to lock the handle assembly and increase the controllability of the equipment.

A sliding column is provided on the locking block 42, and the sliding column slides with the arc groove on the guide plate 43. A spring is connected to the end of the sliding column, and the other end of the spring is installed on the rotating shaft. The spring is used to always push the sliding column outward. The guide plate 43 is fixedly installed on the above-mentioned rotating shaft, and a telescopic handle 46 is fixedly connected to the middle of the rotating shaft. The locking block 42, the guide plate 43, the guide cylinder 44 and the cylinder 45 are symmetrical with respect to the telescopic handle 46.

[0050] The upper end of the protective cover 109 is evenly provided with an axial connection seat, which is used to connect the moving wheel 2, and the moving wheel 2 drives the device to move. The moving wheel 2 includes an L-shaped rotating seat 23, and the L-shaped rotating seat 23 is axially connected to the axial connection seat. A sliding groove is provided on the L-shaped rotating seat 23, and the sliding groove is slidably connected with the sliding column provided on the upper end of the universal wheel 21. A threaded hole is provided on one side of the L-shaped rotating seat 23, and a locking bolt 22 is threadedly connected in the threaded hole. The locking bolt 22 is used to limit the movement of the above-mentioned sliding column. The upper end surface and side surface of the protective cover 109 are provided with a limit assembly 24 corresponding to the moving wheel 2. The limit assembly 24 consists of two limit plates and an L-shaped rotating hinge. The two limit plates are arranged on both sides of the L-shaped rotating seat 23. The rotating shaft of the limit plate on one side is connected to the L-shaped rotating hinge, and the L-shaped rotating hinge is provided with a slot, and the limit plate on the other side is provided with a frame plate matching the above-mentioned slot, and the frame plate is provided with an opening, and a locking pin is installed on the opening to limit the movement of the L-shaped rotating hinge;

[0051] Working principle: When in use, start the driving motor 7, which drives the crank 81 and the gear I82 to rotate the gear I82 and make a circular motion around the inner gear ring 83, and the gear I82 drives the connecting arm 84, which drives the connecting seat 85, and drives the tamping plate 6 to tamp the ground through the connecting seat 85. At the same time, when the tamping plate 6 moves upward, the annular plate at the lower end of the handle turning ring 5 contacts the ground, and the secondary impact increases the tamping efficiency.

[0052] When working, the steering of the traditional rammer needs to drive the whole equipment to move. Since the rammer is too heavy, the rammer plate 6 at the lower end rubs against the ground when it is purely manpower-dependent, and steering increases labor. Therefore, a handle assembly 3 is provided. By providing the handle assembly 3, the sliding steering is achieved through the handle assembly 3 on the handle steering ring 5, which increases convenience. By rotating the bevel gear column II 36, the bevel gear meshes, driving the bevel gear column I 35 to rotate. The bevel gear column I 35 drives the gear to rotate through the universal joint 32. The gear drives the locking columns 33 on both sides to move relative to each other. When the locking columns 33 approach each other, the ends of the locking columns 33 are not inserted into the openings at the upper and lower ends of the handle steering ring 5. The handle assembly 3 is steered to a suitable angle, the handle on the bevel gear column II 36 is released, and the spring on the guide column I 34 rebounds, pushing the locking columns 33 outward, so that the locking columns 33 on both sides move to both sides, and the ends of the locking columns 33 are clamped in the openings on the handle steering ring 5 to lock the steering.

[0053] Since the heights of workers are different, it is necessary to adjust the angle and height of the handle assembly 3. By rotating the rotating handle 41, the guide plate 43 is driven to rotate. The guide plate 43 drives the locking block 42 to move outward through the arc groove above, so that the end of the locking block 42 is inserted into the groove on the cylinder 45, and the rotation of the telescopic handle 46 is restricted. The guide plate 43 is rotated in the opposite direction to make the locking blocks 42 approach each other. The locking blocks 42 do not contact the cylinder 45, and the angle is adjusted. At the same time, the spring on the locking block 42 always gives the locking block 42 a force to move outward. When the rotating handle 41 is released, the locking block 42 automatically inserts into the groove on the inner side of the cylinder 45 and is automatically locked. The telescopic handle 46 is composed of a telescopic column with handles at both ends of the telescopic column for easy holding.

[0054] Embodiment 2:

[0055] On the basis of the first embodiment, a shock absorbing adjustment component is provided at the upper end of the shock absorbing component;

[0056] The shock absorbing adjustment assembly 10 includes a gear ring I 101, a gear ring II 102, a fixing frame 103, a servo motor I 104, a servo motor II 105, a spring II 106, a gear IV 107, a fixing cylinder 108 and a protective cover 109. A gear II 911 is provided on the upper end of the mounting plate on the housing 1. The gear ring II 102 is slidably connected to the mounting plate of the housing 1. The inner ring of the gear ring II 102 is meshed with all the gears II 911. The outer ring of the gear ring II 102 is meshed with a rotating gear at the lower end of the servo motor I 104. A fixing frame 103 is provided on the servo motor I 104. The fixing frame 103 is installed on the protective cover 109. A sliding groove is provided on the fixing frame 103. A servo motor II 105 is connected, and a rotating gear is provided at the lower end of the servo motor II 105. The rotating gear is meshed with the ring gear I 101, and the inner ring of the ring gear I 101 is meshed with all gears III 916. A gear IV 107 is also provided on the ring gear I 101, and the gear IV 107 is correspondingly arranged on the inner and outer sides of the ring gear I 101. A limit plate is provided at the lower end of the ring gear I 101, and the limit plate is used to support the ring gear I 101. A sliding column is provided at the lower end of the limit plate, and the sliding column is slidably inserted in the fixed cylinder 108. A spring is also provided inside the fixed cylinder 108 for lifting the ring gear I 101 to ensure that the ring gear I 101 is always in contact with the lower end of the servo motor II 105 and better meshed with the gear at the lower end of the servo motor II 105.

[0057] When the annular plate contacts the ground, the equipment inside the shell 1 moves downward, which will generate an impact force on the internal equipment, seriously damaging the equipment. Therefore, a shock absorbing component 9 is provided at the lower end of the shell 1. The shock absorbing component 9 absorbs the impact force through the spring Ⅰ915, and prevents the spring Ⅰ915 from rebounding too quickly after being impacted. A damper 914 is also provided to reduce the rebound frequency of the spring Ⅰ915.
