At this time, a small tamping machine is needed to implement the tamping operation. The small tamping machine is usually moved and balanced by a manual hand-held machine body, and then the eccentric wheel in the machine body is driven by a motor to rotate, and the rotation of the eccentric wheel drives the piston rod to move up and down, thereby driving the tamping plate connected to the piston rod to vibrate up and down quickly, and then the tamping operation of the ground is achieved through the up and down vibration of the tamping plate;

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses a tamping device for engineering construction. Figure 2 Figure 3 A construction tamping device includes a body 1, a handrail 2 is fixedly connected to the top of the body 1, a power mechanism 3 for tamping the foundation is arranged at one end of the body 1, and further includes

[0025] A size adjustment mechanism 4, which is located at one end of the power mechanism 3 and is used to adjust and increase the compaction area according to usage requirements;

[0026] A protection mechanism 7, which is located at one end of the handrail 2 and is used to provide power-off protection for the entire device;

[0027] The size adjustment mechanism 4 includes two extension plates 401 and two filling assemblies 6, the power mechanism 3 includes a tamping plate 302, the two extension plates 401 are installed at the bottom of the tamping plate 302 through two limit assemblies 5, and the two filling assemblies 6 are respectively installed at the bottom of the tamping plate 302;

[0028] The limiting assembly 5 includes two limiting slots 501 and two limiting sliders 502. The two limiting slots 501 are symmetrically arranged on the inner side of the bottom of the tamping plate 302. The two ends of the extension plate 401 are slidably connected to the side walls of the two limiting slots 501 through the two limiting sliders 502.

[0029] The filling assembly 6 includes a lifting groove 601, a threaded hole 602, a threaded rod 603 and a filling plate 604. The lifting groove 601 is provided at the bottom of the tamping plate 302, the threaded hole 602 is provided at the top center of the lifting groove 601, the threaded rod 603 is rotatably connected to the top center of the lifting groove 601 by fitting with the threaded hole 602, the side wall of the filling plate 604 is slidably connected to the side wall of the lifting groove 601, and the top center of the filling plate 604 is rotatably connected to the bottom of the threaded rod 603;

[0030] When the compaction area needs to be increased, the threaded rod 603 is rotated through the threaded hole 602 to support the rotation of the threaded rod 603 so that it drives the filling plate 604 connected thereto to slide upward in the provided lifting groove 601, thereby relaxing the pressure on the extension plate 401. At this time, the extension plate 401 set by the provided limiting slide groove 501 is supported and pulled outward so that it can slide and move in the limiting slide groove 501 through the limiting slider 502, thereby sliding out from the bottom of the tamping plate 302, and then the threaded rod 603 is reversed to drive the filling plate 604 connected thereto to slide downward in the lifting groove 601 under force, and the filling plate 604 moves downward to fill the gap left by the extension plate 401 after it is extended, and the extension plate 401 is limited and resisted, so that the extension plate 401 can be extended from the bottom of the tamping plate 302, thereby effectively increasing the tamping area, thereby achieving the effect of effectively improving the tamping efficiency by increasing the tamping area.

[0031] Furthermore, the power mechanism 3 further includes a motor 301, the motor 301 is fixedly connected to the side wall of the machine body 1, and the tamping plate 302 is installed at the bottom of the machine body 1;

[0032] After increasing the tamping area as needed on the basis of the above embodiment, the motor 301 is started to provide force to drive the eccentric wheel in the machine body 1 to rotate, and the rotation of the eccentric wheel drives the piston rod to extend and retract at the bottom of the machine body 1, and then the extension and retraction of the piston rod drives the tamping plate 302 to move up and down. In this way, the tamping plate 302 can be lifted and moved to exert impact force on the ground, and the impact vibration can be used to compact the road surface.

[0033] Furthermore, the protection mechanism 7 includes a relay 701 and an induction component 8, the relay 701 is fixedly connected to the top of the motor 301, and the induction component 8 is installed at one end of the handrail 2;

[0034] The sensing assembly 8 includes a sensing grab bar 801 and a pressure sensor 802. The sensing grab bar 801 is fixedly connected to one end of the handrail 2, and the pressure sensor 802 is fixedly connected to the inner wall of the sensing grab bar 801.

[0035] While the road surface is compacted by the tamping plate 302, the balance of the machine body 1 is controlled and the machine body 1 is moved by the sensing grab bar 801 set at one end of the handheld handrail 2, and the set pressure sensor 802 is used to monitor and sense whether the sensing grab bar 801 is under force in real time. When the worker makes an error in operation and releases the grasping sensing grab bar 801, resulting in loss of control of the machine body 1, the set pressure sensor 802 senses that the sensing grab bar 801 loses force and sends a signal to the single-chip microcomputer, and the single-chip microcomputer sends an instruction to control the set relay 701 to disconnect. At this time, the relay 701 is disconnected to cut off the power to the motor 301 and stop working. In this way, protection by power off can be achieved to avoid the machine slipping out of the hands of the worker due to mistaken operation, thereby causing damage to the worker and the machine.

[0036] The implementation principle of the tamping device for engineering construction in the embodiment of the present application is as follows: when in use, first, when it is necessary to increase the tamping area, the threaded rod 603 is supported and rotated through the threaded hole 602 to drive the filling plate 604 connected thereto to slide upward in the provided lifting groove 601, thereby relaxing the pressure on the extension plate 401. At this time, the extension plate 401 is supported and pulled outward through the provided limiting slide groove 501 to make it slide and move in the limiting slide groove 501 through the limiting slider 502, thereby sliding out from the bottom of the tamping plate 302, and then Then, the threaded rod 603 is reversed to drive the filling plate 604 connected thereto to slide downward in the lifting groove 601 under force, and the filling plate 604 moves downward to fill the vacancy left by the extension plate 401, and the extension plate 401 is limited and offset, so that the extension plate 401 can be extended from the bottom of the tamping plate 302 to effectively increase the tamping area, thereby achieving the purpose of effectively facilitating the adjustment and increase of the tamping area size according to the use needs and improving the tamping efficiency. 1 can control the balance of the machine body 1 and move the machine body 1, and monitor and sense in real time whether the sensing grab bar 801 is under force through the pressure sensor 802. When the worker makes a mistake in the operation and releases the grasping sensing grab bar 801, resulting in loss of control of the machine body 1, the pressure sensor 802 senses that the sensing grab bar 801 loses force and sends a signal to the single chip microcomputer, and the single chip microcomputer sends an instruction to control the relay 701 to disconnect. At this time, the relay 701 is disconnected to cut off the power of the motor 301 and stop working. In this way, protection can be achieved by cutting off the power, avoiding the machine from slipping out of the hands due to the worker's mistake, thereby causing damage to the worker and the machine, and effectively improving the purpose of safety in use. Finally, the motor 301 is started to provide a force to drive the eccentric wheel in the machine body 1 to rotate, and the rotation of the eccentric wheel drives the piston rod to extend and retract at the bottom of the machine body 1, and then the piston rod is extended and retracted to drive the tamping plate 302 to move up and down, so that the tamping plate 302 can be lifted and moved to exert impact force on the ground, and the impact vibration is used to compact the road surface.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
