Description

Technical Field

[0001] The utility model relates to the technical field of highway tamping machines, in particular to a small-sized tamping machine used for highways. Background Art

[0002] Highway refers to a road that connects cities, urban and rural areas, villages and industrial and mining bases, which is built according to national technical standards and approved by the highway authorities. Highways are usually made of a mixture of asphalt and stone. When the asphalt and stone mixture is laid on the highway subgrade, in order to better discharge the air between the asphalt and stone and increase the compactness of the highway after laying, it is usually necessary to use a small rammer to compact the highway road surface using impact and impact vibration.

[0003] The utility model with the existing authorization announcement number CN216275126U discloses a road rammer for highway construction, including a rammer body and an adjustment and limiting mechanism. A rammer column is slidably connected to the inner side of the rammer body. The adjustment and limiting mechanism includes an electric slide and a connecting side plate. A mounting frame is fixedly installed on the outer side of the electric slide, and a support column is fixedly installed on the bottom of the mounting frame.

[0004] By adopting the above technical scheme, the support column is pressed tightly against the top of the compacted ground by adjusting the electric slide to slide to the bottom, and then the user can adjust the compacting column to move to the bottom. When the pulling force detected by the dynamometer reaches the ideal value, the compacting position reaches the ideal height, so that the structure has the advantage of conveniently limiting the compaction height for compaction treatment. However, when the existing small road rammer according to the above technical scheme is used, a metal handrail is usually used to facilitate the staff to manually push the small rammer. The small rammer itself does not have the ability to move automatically, and the staff needs to use a lot of force to smoothly push the small rammer forward, which greatly increases the labor intensity of the staff and affects the overall convenience of using the small rammer.

[0005] Therefore, those skilled in the art provide a small-sized tamping machine for roads to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to provide a small tamping machine for roads to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A small tamping machine for roads comprises a base, a gasoline engine is fixedly connected to the upper surface of the base, and a walking-assisting mechanism is fixedly connected to the left side of the base;

[0009] The walking-assisting mechanism includes a fixed frame, a right side surface of the fixed frame is fixedly connected to the left side surface of the base, a generator is fixedly connected to the upper surface of the base, a first pulley is sleeved on the outer surface of the output end of the gasoline engine, the inner wall of the first pulley is in contact with the outer surface of the rotor of the generator, a battery is fixedly connected to the upper surface of the base, and the battery is electrically connected to the generator through a wire, three compression springs are fixedly connected to the bottom surface of the fixed frame, and the bottom ends of the three compression springs are commonly fixedly connected to a connecting plate, a bidirectional motor is arranged below the connecting plate, and the bidirectional motor is electrically connected to the battery through a wire, two output ends of the bidirectional motor are fixedly connected to reducers, the upper surface of each reducer is fixedly connected to the bottom surface of the connecting plate, and the output end of each reducer is fixedly connected to a rotating wheel, and two support rods are fixedly connected to the upper surface of the fixed frame, and a speed regulating handle is fixedly connected to the front side of one of the support rods, and the speed regulating handle is electrically connected to the bidirectional motor.

[0010] As a further solution of the utility model: a vibrator is fixedly connected to the upper surface of the base, an input end of the vibrator and an output end of the gasoline engine are jointly sleeved with a second pulley, and a tamping plate is fixedly connected to the bottom surface of the base.

[0011] As a further solution of the utility model: a telescopic rod is arranged inside each compression spring, the telescopic end of each telescopic rod is fixedly connected to the bottom surface of the fixing frame, and the bottom end of each telescopic rod is fixedly connected to the upper surface of the connecting plate.

[0012] As a further solution of the utility model: the upper surface of the bidirectional motor is fixedly connected with a stabilizing seat, and the upper surface of the stabilizing seat is fixedly connected to the bottom surface of the connecting plate.

[0013] As a further solution of the utility model: the outer surface of each output end of the reducer is rotatably connected to a bearing seat, and the upper surface of each bearing seat is fixedly connected to the bottom surface of the connecting plate.

[0014] As a further solution of the utility model: the right side surface of each support rod is fixedly connected with a reinforcing rib, and the bottom surface of each reinforcing rib is fixedly connected to the upper surface of the fixing frame.

[0015] As a further solution of the utility model: a stabilizing plate is fixedly connected to one side of the two support rods close to each other, a handle is fixedly connected to the back of the other support rod, and an anti-slip sleeve is fixedly connected to the outer surface of the handle.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model is provided with a first pulley to cooperate with the gasoline engine. When the gasoline engine is working, it can drive the internal rotor of the generator to rotate, and then can generate electricity by cutting the magnetic flux lines, and the electricity is stored in the battery through the wire. When the small highway rammer needs to move forward during use, it only needs to cooperate with the support rod to manually turn the speed regulating handle to transmit the electrical signal to the motor controller of the two-way motor. The motor controller of the two-way motor adjusts the output to the pulse width according to the received signal, so as to control the speed of the two-way motor and start and stop. When the two-way motor rotates with the electric energy provided by the battery, it can drive the reducer to rotate in cooperation with the connecting plate, and the speed is reduced by the reducer After being lowered, the rotating wheel is driven to rotate, thereby assisting the staff to push the small rammer forward gradually. The small highway rammer cooperates with the walking-assisting mechanism without the staff having to use both hands to forcibly push the small rammer forward. The small rammer itself has a certain automatic moving ability and does not require external power intervention, which effectively reduces the labor intensity of the staff and increases the overall convenience of using the small rammer. The elastic force provided by the compression spring is used in conjunction with the fixed frame and the connecting plate, which can not only reduce the impact of the base vibration on the two-way motor and other equipment, but also it is not easy to reduce the tamping effect of the small rammer due to the forward movement of the small rammer, thereby ensuring the normal tamping work of the small rammer.

[0024] The walking-assisting mechanism 3 includes a fixed frame 301, the right side surface of the fixed frame 301 is fixedly connected to the left side surface of the base 1, a generator 302 is fixedly connected to the upper surface of the base 1, a first pulley 303 is sleeved on the outer surface of the output end of the gasoline engine 2, the inner wall of the first pulley 303 is in contact with the outer surface of the rotor of the generator 302, a battery 304 is fixedly connected to the upper surface of the base 1, and the battery 304 is electrically connected to the generator 302 through a wire, three compression springs 305 are fixedly connected to the bottom surface of the fixed frame 301, and the bottom ends of the three compression springs 305 are commonly fixedly connected to a connecting plate 306, and a telescopic rod 7 is arranged inside each compression spring 305, and the telescopic end of each telescopic rod 7 is fixedly connected to the bottom surface of the fixed frame 301, and the bottom end of each telescopic rod 7 is fixedly connected to the upper surface of the connecting plate 306, and the telescopic rod 7 can prevent the compression spring 305 from deflecting and increase the horizontal force strength of the compression spring 305, so as to ensure that the fixed frame 301 cooperates with the connecting plate 306 to smoothly push the base 1 forward.

[0025] A bidirectional motor 307 is arranged below the connecting plate 306. The bidirectional motor 307 is electrically connected to the battery 304 through a wire. The upper surface of the bidirectional motor 307 is fixedly connected to a stabilizing seat 8. The upper surface of the stabilizing seat 8 is fixedly connected to the bottom surface of the connecting plate 306. The stabilizing seat 8 can fix the position of the bidirectional motor 307 on the connecting plate 306, thereby increasing the connection firmness between the bidirectional motor 307 and the connecting plate 306 and ensuring the normal use of the bidirectional motor 307.

[0026] The two output ends of the bidirectional motor 307 are fixedly connected to the reducers 308, the upper surface of each reducer 308 is fixedly connected to the bottom surface of the connecting plate 306, and the outer surface of each output end of the reducer 308 is rotatably connected to the bearing seat 9, and the upper surface of each bearing seat 9 is fixedly connected to the bottom surface of the connecting plate 306. The bearing seat 9 can increase the rotation stability of the output end of the reducer 308 and share the pressure of the output end of the reducer 308 to a certain extent, thereby improving the rotation reliability of the output end of the reducer 308.

[0027] The output end of each reducer 308 is fixedly connected to a rotating wheel 309, and the upper surface of the fixed frame 301 is fixedly connected to two support rods 310. The right side of each support rod 310 is fixedly connected to a reinforcing rib 10, and the bottom surface of each reinforcing rib 10 is fixedly connected to the upper surface of the fixed frame 301.

[0028] The front side of one of the support rods 310 is fixedly connected with a speed regulating knob 311. The principle of the speed regulating knob 311 is to adjust the speed of the motor by changing the pulse speed output by the motor controller. When the speed regulating knob 311 is turned, the Hall sensor inside the speed regulating knob 311 will sense the change in the handle angle and send this signal to the motor controller. The motor controller determines the output pulse width according to the received signal. The larger the pulse width, the faster the motor speed. Conversely, the motor speed decreases. The speed regulating knob 311 is electrically connected to the bidirectional motor 307. The side of the two support rods 310 that are close to each other is commonly fixedly connected with a stabilizing plate 11. The back side of the other support rod 310 is fixedly connected with a handle 12. The outer surface of the handle 12 is fixedly connected with an anti-slip sleeve 13. The stabilizing plate 11 can further improve the reliability of the use of the two support rods 310. The handle 12 cooperates with the anti-slip sleeve 13 and the support rod 310, which can facilitate the staff to control the running direction of the device, thereby increasing the manual operation stability of the device.

[0029] The working principle of the utility model is as follows: when it is necessary to perform vibration and tamping work on the paved asphalt road surface, the gasoline engine 2 can work in conjunction with the second pulley 5 to drive the vibrator 4 to rotate, and the eccentric block inside the vibrator 4 can generate vibration, so that the base 1 and the vibration and tamping plate 6 vibrate to perform vibration and tamping work on the asphalt road surface after the road is paved. When the crankshaft inside the gasoline engine 2 rotates, it can also cooperate with the first pulley 303 to drive the internal rotor of the generator 302 to rotate, and then it can generate electrical energy by cutting the magnetic flux lines, and this electrical energy is stored in the battery 304 through the wire. When the small highway tamping machine needs to move forward during use, it only needs to cooperate with the handle 12 and the support rod 310 to manually rotate the speed regulating knob 311, so that the changes in the electrical signals of the sensors inside the speed regulating knob 311 can be transmitted to the motor controller of the bidirectional motor 307. The motor controller of the bidirectional motor 307 adjusts the output to the pulse width according to the received signal, thereby controlling the rotation of the bidirectional motor 307. Speed ​​and start and stop. When the bidirectional motor 307 rotates using the electric energy provided by the battery 304, the connecting plate 306 can drive the reducer 308 to rotate. The reducer 308 is used to reduce the speed and then drive the rotating wheel 309 to rotate, thereby assisting the staff to push the small tamping machine to move forward gradually, so that the small highway tamping machine cooperates with the walking-assisting mechanism 3 without the need for the staff to use both hands to forcibly push the small tamping machine forward, so that the small tamping machine itself has a certain automatic moving ability and does not require external power intervention, which effectively reduces the labor intensity of the staff and increases the overall convenience of use of the small tamping machine. Finally, the elastic force provided by the compression spring 305 is used in conjunction with the limiting of the fixed frame 301, the connecting plate 306 and the telescopic rod 7, which can not only reduce the impact of the vibration of the base 1 on the bidirectional motor 307 and other equipment, but also it is not easy to reduce the tamping effect of the small tamping machine due to the forward movement of the small tamping machine, thereby ensuring the normal tamping work of the small tamping machine.
