Description

Technical Field

[0001] The invention relates to a building construction tamping device, belonging to the technical field of building construction. Background Art

[0002] Tamping is a method of using heavy objects to repeatedly impact the ground to increase soil density. Common tamping methods include manual tamping and mechanical tamping. Manual tamping may use wood tamping or stone tamping, while mechanical tamping may use frog tamping machines or impact tamping machines. The main function of tamping is to increase the bearing capacity of the foundation, prevent settlement, and reduce water seepage.

[0003] There are many types of tamping equipment, mainly including two types. One is a purely mechanical tamping equipment suitable for large sites, such as a tamping machine using an excavator and a large roller. The other is a tamping equipment suitable for small sites that requires manual operation. The tamping equipment suitable for small sites mainly includes frog-type tamping machines and small vertical impact tamping machines. The compaction required for foundations in different scenarios is different, especially for foundations in small sites, which often do not require too high a degree of compaction. The use of large tamping equipment is too expensive and inconvenient to use. It is more appropriate to use a small tamping equipment with manual operation. However, no matter which type or which small tamping equipment is currently available, the tamping force cannot be adjusted, and it is impossible to make targeted adjustments to the compaction requirements of different foundations. Different tamping equipment can only be replaced, which often affects the progress of the project and is more expensive. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problems of low tamping operation efficiency and high cost in the prior art, and to provide a tamping device for building construction.

[0005] The present invention is achieved through the following technical solutions: That is, a tamping device for construction, comprising a frame, a tamping component for tamping the foundation is installed at the bottom of the frame, the frame comprises two end plates, the tops of the two end plates are connected by a top plate, a handle is provided on one end plate, and a walking wheel is installed at the bottom of the end plate; Two through holes are provided on the top plate, and two threaded sleeves are fixedly provided on the top plate, and the threaded sleeves are concentrically connected with the through holes, and a vertical down-punch adjustable mechanism is installed in the threaded sleeves, and the vertical down-punch adjustable mechanism includes a threaded spring, and an upper connecting plate is installed at the bottom of the vertical down-punch adjustable mechanism, and a counterweight is fixedly provided at the bottom of the upper connecting plate, and the vertical down-punch adjustable mechanism is connected to the threaded sleeves and the upper connecting plate through threads, and the upper and lower positions of the threaded springs can be adjusted by rotating the vertical down-punch adjustable mechanism; A motor is installed in the end plate, and a rotating lifting mechanism is installed on the main shaft of the motor. The upper connecting plate is lifted cyclically by the rotation of the rotating lifting mechanism.

[0006] The rotation of the motor drives the rotating lifting mechanism, which rotates continuously and repeatedly to push the upper connecting plate upward, squeezes the threaded spring upward, and stores energy in the threaded spring. Whenever the rotating lifting mechanism rotates away from the upper connecting plate, the upper connecting plate is released, and the threaded spring releases energy, driving the counterweight block downward to impact the foundation again and again. According to the requirements of the compaction degree of the foundation of different sites, the upper and lower positions of the threaded spring are adjusted by rotating the vertical downward punch adjustable mechanism. The lower the position of the threaded spring, the greater the amplitude of the upper connecting plate pushed by the rotating lifting mechanism, the greater the energy stored in the threaded spring, and the greater the impact and compaction degree of the foundation. The higher the position of the threaded spring, the opposite is true. Using the tamping machine of the present invention for tamping operations can meet the compaction requirements of more different site foundations and greatly reduce construction costs.

[0007] Further preferably, a top screw is installed on the outer circumference of the threaded sleeve, and the inner end of the top screw is in contact with the vertical downward punch adjustable mechanism. Continuous impact and tamping have a greater impact on the vertical downward punch adjustable mechanism, and the top screw has a better fixing effect on the vertical downward punch adjustable mechanism, and can also reduce the damage to the thread caused by impact vibration.

[0008] Further preferably, a pressure plate is detachably mounted on the bottom of the counterweight block, and the edge of the pressure plate is bent upward, so that different pressure plates can be replaced for different usage environments.

[0009] Further preferably, the rotating lifting mechanism includes a straight rod mounted on the main shaft of the motor, with levers hinged at both ends of the straight rod, and a gas spring hingedly mounted between the lever and the straight rod, and the two gas springs are located on different upper and lower sides of the straight rod. If a completely rigid straight rod is used to directly push the upper connecting plate upward, the noise will be very loud and the motor will be easily damaged. The use of a flexible pushing structure can reduce the noise and also protect the motor.

[0010] Further preferably, an upper disc is fixed at the upper end of the threaded spring, an upper nut is fixed at the upper end of the upper disc, a lower nut is fixed at the bottom end of the threaded spring, the threaded portion of the upper nut is located in the threaded sleeve, two threaded holes are provided on the upper connecting plate, and the lower nut is installed in the threaded holes.

[0011] Preferably, the threaded portion of the upper nut is longer than the threaded sleeve, and a horizontal through hole is provided on the upper nut. A tool is passed through the through hole to rotate the vertical punch adjustable mechanism to adjust the impact force, and the threaded portion of the upper nut is longer to ensure room for adjustment.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The rotation of the motor drives the rotating lifting mechanism, which rotates continuously and repeatedly to push the upper connecting plate upward, squeezes the threaded spring upward, and stores energy in the threaded spring. Whenever the rotating lifting mechanism rotates away from the upper connecting plate, the upper connecting plate is released, and the threaded spring releases energy, driving the counterweight block downward to impact the foundation again and again. According to the requirements of the compaction degree of the foundation of different sites, the upper and lower positions of the threaded spring are adjusted by rotating the vertical downward punch adjustable mechanism. The lower the position of the threaded spring, the greater the amplitude of the upper connecting plate pushed by the rotating lifting mechanism, the greater the energy stored in the threaded spring, and the greater the impact and compaction degree of the foundation. The higher the position of the threaded spring, the opposite is true. Using the tamping machine of the present invention for tamping operations can meet the compaction requirements of more different site foundations and greatly reduce construction costs.

[0020] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 A construction tamping device shown in the figure comprises a frame, a tamping component for tamping the foundation is installed at the bottom of the frame, the frame comprises two end plates 1, the tops of the two end plates 1 are connected by a top plate 3, a handle 2 is provided on one end plate 1, and a walking wheel 7 is installed at the bottom of the end plate 1; Two through holes are provided on the top plate 3, and two threaded sleeves 4 are fixedly provided on the top plate 3. The threaded sleeves 4 are concentrically connected with the through holes, and a vertical down-punch adjustable mechanism 6 is installed in the threaded sleeve 4. The vertical down-punch adjustable mechanism 6 includes a threaded spring 17. An upper connecting plate 11 is installed at the bottom of the vertical down-punch adjustable mechanism 6, and a counterweight block 12 is fixedly provided at the bottom of the upper connecting plate 11. The vertical down-punch adjustable mechanism 6 is connected to the threaded sleeve 4 and the upper connecting plate 11 through threads, and the upper and lower positions of the threaded spring 17 can be adjusted by rotating the vertical down-punch adjustable mechanism 6; A motor 8 is installed in the end plate 1 , and a rotating lifting mechanism 9 is installed on the main shaft of the motor 8 . The upper connecting plate 11 is lifted cyclically by the rotation of the rotating lifting mechanism 9 .

[0022] The rotation of the motor 8 drives the rotating lifting mechanism 9, which rotates continuously and repeatedly to push the upper connecting plate 11 upward, and squeezes the threaded spring 17 upward. The threaded spring 17 stores energy. Whenever the rotating lifting mechanism 9 rotates away from the upper connecting plate 11, the upper connecting plate 11 is released, and the threaded spring 17 releases energy, driving the counterweight 12 downward to continuously impact the foundation again and again. According to the requirements of the compaction degree of the foundation of different sites, the upper and lower positions of the threaded spring 17 are adjusted by rotating the vertical downward punch adjustable mechanism 6. The lower the position of the threaded spring 17, the greater the amplitude of the rotating lifting mechanism 9 to push the upper connecting plate 11, the greater the energy storage of the threaded spring 17, and the greater the impact and compaction degree of the foundation. The higher the position of the threaded spring 17, the opposite is true. Using the tamping machine of the present invention for tamping operations can meet more different site foundation compaction requirements and greatly reduce construction costs.

[0023] Among them, a top screw 5 is installed on the outer circumferential surface of the threaded sleeve 4, and the inner end of the top screw 5 is in contact with the vertical downward punch adjustable mechanism 6. Continuous impact and tamping have a greater impact on the vertical downward punch adjustable mechanism 6, and the top screw 5 has a good fixing effect on the vertical downward punch adjustable mechanism 6, and can also reduce the damage to the thread caused by impact vibration.

[0024] A pressing plate 13 is detachably mounted on the bottom of the counterweight block 12 , and the edge of the pressing plate 13 is bent upward, so that different pressing plates 13 can be replaced for different use environments.

[0025] like Figure 5As shown, the rotating lifting mechanism 9 includes a straight rod 23 mounted on the main shaft of the motor 8, with levers 24 hinged at both ends of the straight rod 23, a gas spring 26 hingedly mounted between the lever 24 and the straight rod 23, a hinged rod 25 fixedly arranged on the straight rod 23, one end of the gas spring 26 is hingedly connected to the hinged rod 25, and the two gas springs 26 are located on different sides of the straight rod 23. If the completely rigid straight rod 23 is used to directly push the upper connecting plate 11 upward, the noise will be very loud and the motor 8 will be easily damaged. The flexible pushing structure can reduce the noise and also protect the motor 8.

[0026] Among them, an upper disc 16 is fixedly provided at the upper end of the threaded spring 17, an upper nut 14 is fixedly provided at the upper end of the upper disc 16, a lower nut 18 is fixedly provided at the bottom end of the threaded spring 17, the threaded portion of the upper nut 14 is located in the threaded sleeve 4, two threaded holes 19 are provided on the upper connecting plate 11, and the lower nut 18 is installed in the threaded hole 19.

[0027] The threaded portion of the upper nut 14 is longer than the threaded sleeve 4, and a horizontal through hole is provided on the upper nut 14. A tool is used to pass through the through hole to rotate the vertical punch adjustable mechanism 6 to adjust the impact force. The threaded portion of the upper nut 14 is longer, which can ensure room for adjustment.

[0028] Among them, two rubber horizontal buffer mechanisms 10 are arranged between the top plate 3 and the upper connecting plate 11. The horizontal buffer mechanism 10 includes a lower rubber column 21 and an upper rubber column 22 which are sleeved together. Two blind holes 20 are arranged on the upper end surface of the connecting plate 11. The lower part of the lower rubber column 21 is located in the blind hole 20, and the top of the rubber column 22 is fixedly connected to the lower end surface of the top plate 3. The horizontal buffer mechanism 10 has a good buffering and shock absorbing effect on the threaded spring 17 and each thread in the horizontal surface, thereby extending the service life.

[0029] Working principle: The rotation of the motor 8 drives the rotating lifting mechanism 9, which rotates continuously and repeatedly to push the upper connecting plate 11 upward, and squeezes the threaded spring 17 upward. The threaded spring 17 stores energy. Whenever the rotating lifting mechanism 9 rotates away from the upper connecting plate 11, the upper connecting plate 11 is released, and the threaded spring 17 releases energy, driving the counterweight 12 downward to continuously impact the foundation. According to the requirements of the compaction degree of the foundation of different sites, the upper and lower positions of the threaded spring 17 are adjusted by rotating the vertical downward punch adjustable mechanism 6. The lower the position of the threaded spring 17, the greater the amplitude of the upper connecting plate 11 pushed by the rotating lifting mechanism 9, the greater the energy stored by the threaded spring 17, and the greater the impact and compaction degree of the foundation. The higher the position of the threaded spring 17, the opposite is true.
