Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to a repair and leveling device for road maintenance. Background Technology

[0002] Road maintenance aims to maintain roads in good condition and ensure safe and smooth traffic. It encompasses daily inspections to remove debris and repair small potholes; preventative maintenance such as sealing to prevent damage; periodic major and minor repairs, such as repaving and bridge / culvert repair; and emergency repairs in response to disasters. Road rammers are commonly used equipment in road maintenance and other construction work. They compact soil, gravel, asphalt, etc., through impact and vibration. In road maintenance operations, road rammers are frequently used to compact and level gravel, asphalt, etc., thereby improving the quality of maintenance work.

[0003] Existing road maintenance rammers mostly have non-movable connection structures between their compaction section and main body. The compaction section cannot be vibrated independently. When the rammer is working, the entire equipment will vibrate, resulting in a certain waste of kinetic energy. Furthermore, the severe vibration will cause other parts of the rammer to be subjected to strong impact forces, reducing the service life of the rammer. At the same time, due to the violent shaking of the rammer, it will also cause a strong tremor in the operator's hands, increasing the difficulty of operating the rammer.

[0004] Therefore, there is an urgent need to provide a road maintenance repair and leveling device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a road maintenance repair and leveling device.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a road maintenance repair and leveling device is provided, including a tamping plate mechanism and a driving mechanism. The top of the tamping plate mechanism is slidably provided with a frame mechanism for installing various components, and the top of the frame mechanism is fixed with a driving mechanism for outputting power.

[0007] The output end of the drive mechanism is connected to an excitation mechanism;

[0008] The frame structure is also fixed with a tensioning mechanism for maintaining belt tension.

[0009] The present invention is further configured such that: the tamping plate mechanism includes a plate body, a plurality of sliding ears are fixed on the plate body, a damper is also fixed on the plate body, and a plurality of shock-absorbing springs are also fixed at the top of the plate body.

[0010] Through the above technical solutions, the damping spring can effectively absorb the kinetic energy of vibration, the damper can effectively absorb the vibration generated when the damping spring rebounds, and the damper and the damping spring working together can effectively prevent the kinetic energy of the plate from being transmitted to the frame mechanism.

[0011] The present invention is further configured such that: the frame mechanism includes a base plate fixed to the top of the shock-absorbing spring, a plurality of sliders are fixed on the base plate, and a protective frame and a handrail are also fixed to the top of the base plate.

[0012] Through the above technical solution, the base plate is fixed to the top of the damper, and the slider is slidably connected to the sliding ear, thereby realizing the movable connection between the impact component and the main body, thus reducing kinetic energy waste, reducing the vibration of the device to the operator's hands when operating the device, reducing the difficulty of operation, the protective frame can protect the drive mechanism, and the handrail can be used by the operator to control the device.

[0013] The present invention is further configured such that: the driving mechanism includes an engine fixed to the base plate, and the output end of the engine is connected to an output shaft.

[0014] With the above technical solution, the engine is a gasoline engine or a diesel engine, and the output shaft will rotate when the engine is started.

[0015] The present invention is further configured such that: an oil tank is fixed on the engine, and an oil filter and an oil box are also fixed on the engine.

[0016] Through the above technical solutions, the fuel tank can be used to store fuel, the filter can filter out impurities in the air and reduce the wear of parts such as valves, cylinders, and pistons, and the oil box can store engine oil to lubricate various parts of the engine.

[0017] The present invention is further configured such that: the excitation mechanism includes a pulley one fixed on the output shaft, a transmission belt is sleeved on the outside of the pulley one, and a pulley two is sleeved on the other end of the transmission belt; the excitation mechanism also includes an eccentric exciter fixed on the plate.

[0018] Through the above technical solution, the shaft of pulley two is fixed to the eccentric wheel in the eccentric vibrator. When the output shaft rotates, pulley one will also rotate, thereby driving pulley two to rotate through the transmission belt. Pulley two can drive the eccentric wheel in the eccentric vibrator to rotate, thereby driving the plate to generate impact force on the ground that needs to be leveled.

[0019] The present invention is further configured such that: the tensioning mechanism includes a mounting bracket fixed to the base plate, the mounting bracket has a sliding groove, a tensioning spring is fixed on the mounting bracket, the other end of the tensioning spring is connected to a sliding frame, and a tensioning wheel is rotatably connected to the inner side of the sliding frame.

[0020] With the above technical solution, the sliding frame is slidably connected to the slide groove, the tensioning wheel is in contact with the lower part of the transmission belt, and the tensioning spring can pull the sliding frame and the tensioning wheel upward, so that the transmission belt always remains taut and avoids transmission failure caused by changes in the distance between pulley two and pulley one when the device is working.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model achieves a movable connection between the main body and the compaction part through the arrangement of the tamping plate mechanism, the frame mechanism and the excitation mechanism.

[0023] 2.

[0032] Please see Figures 1-6 A road maintenance repair and leveling device includes a tamping plate mechanism 1 and a driving mechanism 3. The tamping plate mechanism 1 includes a plate body 101, a plurality of sliding ears 102 are fixed on the plate body 101, a damper 103 is also fixed on the plate body 101, and a plurality of shock-absorbing springs 104 are also fixed at the top of the plate body 101. The shock-absorbing springs 104 can effectively absorb the vibration kinetic energy, and the damper 103 can effectively absorb the vibration generated when the shock-absorbing springs 104 rebound. The damper 103 and the shock-absorbing springs 104 work together to effectively prevent the kinetic energy of the plate body 101 from being transmitted to the frame mechanism 2.

[0033] like Figure 1 and Figure 3 As shown, the top of the ramming plate mechanism 1 is slidably equipped with a frame mechanism 2 for installing various components. The frame mechanism 2 includes a base plate 201 fixed to the top of the shock-absorbing spring 104. Multiple sliders 202 are fixed on the base plate 201. A protective frame 203 and a handrail 204 are also fixed to the top of the base plate 201. The base plate 201 is fixed to the top of the damper 103. The sliders 202 are slidably connected to the sliding ears 102, thereby realizing the movable connection between the impact component and the main body, thereby reducing kinetic energy waste, and also reducing the vibration of the device to the operator's hands when operating the device, reducing the difficulty of operation. The protective frame 203 can protect the drive mechanism 3, and the handrail 204 can be used by personnel to control the device.

[0034] like Figure 1 and Figure 4 As shown, a drive mechanism 3 for outputting power is fixed at the top of the frame mechanism 2. The drive mechanism 3 includes an engine 301 fixed on the base plate 201. The output end of the engine 301 is connected to an output shaft 302. An oil tank 303 is fixed on the engine 301. An air filter 304 and an oil box 305 are also fixed on the engine 301. The engine 301 is a gasoline engine 301 or a diesel engine 301. When the engine 301 starts, the output shaft 302 will rotate. The oil tank 303 can be used to store fuel. The air filter 304 can filter out impurities in the air and reduce the wear of parts such as valves, cylinders, and pistons. The oil box 305 can store oil and lubricate the various parts of the engine 301.

The excitation mechanism 4 includes a pulley 401 fixed on the output shaft 302. A transmission belt 402 is sleeved on the outside of the pulley 401. A pulley 403 is sleeved on the other end of the transmission belt 402. The excitation mechanism 4 also includes an eccentric vibrator 404 fixed on the plate 101. The axis of the pulley 403 is fixed to the eccentric wheel in the eccentric vibrator 404. When the output shaft 302 rotates, the pulley 401 will also rotate, thereby driving the pulley 403 to rotate through the transmission belt 402. The pulley 403 can drive the eccentric wheel in the eccentric vibrator 404 to rotate, thereby driving the plate 101 to generate an impact force on the ground that needs to be leveled.

[0036] like Figure 1 and Figure 6 As shown, a tensioning mechanism 5 for maintaining belt tension is also fixed on the frame mechanism 2. The tensioning mechanism 5 includes a mounting bracket 501 fixed on the base plate 201. A sliding groove 502 is provided on the mounting bracket 501. A tensioning spring 503 is also fixed on the mounting bracket 501. The other end of the tensioning spring 503 is connected to a sliding frame 504. A tensioning wheel 505 is rotatably connected to the inner side of the sliding frame 504. The sliding frame 504 is slidably connected to the sliding groove 502. The tensioning wheel 505 is in contact with the lower part of the transmission belt 402. The tensioning spring 503 can pull the sliding frame 504 and the tensioning wheel 505 upward, so that the transmission belt 402 is always kept taut, avoiding transmission failure due to changes in the distance between the second pulley 403 and the first pulley 401 when the device is working.

[0037] When using this utility model, the staff first moves the device to the position that needs to be leveled, and then starts the drive mechanism 3. At this time, the drive mechanism 3 drives the vibration mechanism 4 to operate, and the vibration mechanism 4 drives the tamping plate mechanism 1 to continuously impact the ground, thereby leveling the asphalt on the ground. The tensioning mechanism 5 effectively reduces the loss of kinetic energy.
