A ramming device

Abstract

This utility model discloses a tamping device, including a platform, a gantry frame fixed to one side of the upper surface of the platform, and a horizontal plate fixed in the middle of the gantry frame. A square hole is formed in the middle of the horizontal plate, and a square rod is slidably connected inside the square hole. A square tube is slidably connected to the bottom surface of the square rod, and a side hole is formed on the top side wall of the square tube. A locking component for fixing the square tube is provided inside the side hole, and a tamping plate is fixed to the bottom end of the square tube. In this utility model, the device includes a platform, gantry frame, horizontal plate, square rod, square tube, tamping plate, locking component, drive component, and counterweight component. When the tamping stroke needs to be adjusted, the square tube can be slid up and down along the square rod to adjust the initial height of the tamping plate, and then the square tube can be fixed by the locking component. The adjustment structure is simpler and more convenient, and does not require an oil pump. Furthermore, the counterweight component increases the stability of the platform, preventing the device from jumping upwards during tamping.

Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a tamping device. Background Technology

[0002] A rammer is a machine used for compaction, primarily for compacting and leveling poured materials on the ground. Especially in building construction, after the foundation is poured, a rammer is needed to compact the ground and improve its stability. Most rammers currently available are diesel-powered, which are noisy and cumbersome to operate.

[0003] A search revealed that patent CN218711979U discloses a tamping device for building construction. It uses a motor to drive a shaft and a circular plate to rotate. The rotation of the circular plate causes a connecting rod, a rectangular rod, and a tamping block to move up and down reciprocally, thus achieving the tamping operation. If the downward stroke of the tamping block needs adjustment, the operator activates a hydraulic cylinder to lower the moving plate and tamping components, thereby increasing the downward distance of the tamping block. However, in actual use, this device requires an additional oil pump to match the hydraulic cylinder, making the structure more complex. Secondly, insufficient weight can cause the device to bounce upwards when the tamping block contacts the ground. Furthermore, the device relies entirely on manual pushing, which is very strenuous on muddy ground, thus requiring further improvement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tamping device.

[0009] Furthermore, a battery is installed on the upper surface of the vehicle panel, and both the first motor and the dual-axis motor are electrically connected to the battery. The top of the push handle is equipped with control buttons for controlling the first motor and the dual-axis motor.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a tamping device is disclosed, comprising a platform 1, a gantry frame 2 fixed to one side of the upper surface of the platform 1, and a horizontal plate 3 fixed in the middle of the gantry frame 2. A square hole 31 is provided in the middle of the horizontal plate 3, and a square rod 4 is slidably connected inside the square hole 31. A square tube 5 is slidably connected to the bottom surface of the square rod 4. A side hole 51 is provided on the side wall of the top of the square tube 5, and a locking component 7 for fixing the square tube 5 is provided inside the side hole 51. A tamping plate 6 is fixed to the bottom of the square tube 5. A driving component 8 for driving the square rod 4 to move up and down is fixed to the top of the gantry frame 2. A counterweight component 9 is provided on the side of the upper surface of the platform 1. Support plates 10 are fixed on both sides of the lower surface of the platform 1. Drive wheels 11 are rotatably connected to the surfaces of the two support plates 10. A dual-axis motor 12 for driving the two drive wheels 11 to rotate is installed on the lower surface of the platform 1. Two traveling wheels 13 are installed on the side of the lower surface of the platform 1 away from the drive wheels 11. A push handle 15 is installed on the upper surface of the platform 1. An opening 101 is provided on the platform 1 directly below the tamping plate 6.

[0024] The locking assembly 7 includes a plug rod 71 that is slidably connected inside the side hole 51. One end of the plug rod 71 located outside the square tube 5 is fixedly connected to an end cap 72. The end cap 72 and the outer wall of the square tube 5 are fixedly connected to a tension spring 73. The square rod 4 has several positioning holes 41 for inserting the plug rod 71.

[0025] If it is necessary to adjust the initial height of the tamping plate 6 to change the tamping stroke, first pull the insert rod 71 out of the positioning hole 41 currently engaged with the square rod 4 by pulling the end cap 72. Then slide the square tube 5 up and down along the square rod 4 so that the insert rod 71 is aligned with another positioning hole 41. Then loosen the end cap 72 and the tension spring 73 pulls the end cap 72 to reset, so that the insert rod 71 is engaged in the other positioning hole 41, thereby changing the overall length of the square rod 4 and the square tube 5, thus realizing the adjustment of the initial height of the tamping plate 6.

[0026] The two ends of the ramming plate 6 are designed to be bent upwards.

[0027] The drive assembly 8 includes a vertical plate 81 fixed to the top of the gantry 2. A first motor 82 is fixed to the surface of the vertical plate 81. A circular plate 83 is fixedly connected to the output shaft of the first motor 82. A connecting rod 84 is rotatably connected to the surface of the circular plate 83 via a pin. The other end of the connecting rod 84 is hinged to the top of the square rod 4.

[0028] When the first motor 82 drives the circular plate 83 to rotate, the connecting rod 84 will drive the square rod 4 to move up and down along the square hole 31, thereby driving the square tube 5 and the ramming plate 6 to rise and fall.

[0029] A battery 14 is installed on the upper surface of the vehicle plate 1. The first motor 82 and the dual-axis motor 12 are electrically connected to the battery 14. The top of the push handle 15 is equipped with control buttons for controlling the first motor 82 and the dual-axis motor 12.

[0030] The battery 14 can power the first motor 82 and the dual-axis motor 12. The dual-axis motor 12 is a geared motor.

[0031] The output shafts on both sides of the dual-axis motor 12 are fixedly connected to the centers of the two drive wheels 11, respectively.

[0032] The two drive wheels 11 can be driven to rotate by the dual-axis motor 12, thereby enabling the device to move with assistance.

[0033] The counterweight assembly 9 includes a vertical rod 91 fixed to the upper surface of the vehicle plate 1, and a plurality of annular counterweight blocks 92 are sleeved on the surface of the vertical rod 91.

[0034] The counterweight 92 can increase the stability of the vehicle plate 1 and prevent the device from jumping up when the ramming plate 6 contacts the ground.

[0035] Working principle: First, adjust the initial height of the tamping plate 6 according to the soil compaction. After adjustment, push the device to move by pushing the handle 15. During the movement, start the first motor 82 and the dual-axis motor 12. The first motor 82 drives the circular plate 83 to rotate, thereby driving one end of the connecting rod 84 to make a circular motion. The other end of the connecting rod 84 will drive the square rod 4 to move up and down, thereby driving the square tube 5 and the tamping plate 6 to vibrate up and down. The tamping plate 6 moves up and down through the opening 101, and the tamping plate 6 is used to compact the soil. The dual-axis motor 12 drives the drive wheel 11 to rotate, thereby assisting the movement of the device.
