Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a ground compacting device for building construction. Background Art

[0002] The ground compaction device for construction is a mechanical device specially designed to enhance the stability and density of the foundation. It compacts the ground layer such as soil, gravel, sand and gravel mixture or backfill material through different working principles and technical means to ensure the stability and durability of the subsequent building structure. This type of device plays a key role in the construction of various buildings, roads, bridges, dams and other infrastructure.

[0003] The frog-leaping rammer, usually referred to as a frog-leaping rammer, is a type of engineering machinery designed for layered compaction of soil or other filling materials. It is named because its dynamic shape when working resembles a frog jumping. This type of rammer is mainly used in foundation treatment, ground leveling and backfill compaction of small projects in construction. It is particularly suitable for operations in narrow or limited spaces. The frog-leaping rammer is widely used in small construction sites, garden landscape construction, pipeline trench backfilling and other fields due to its easy operation, flexibility, high compaction efficiency and low cost.

[0004] Although the frog-leaping rammer in the prior art meets the use requirements to a certain extent, the center of gravity of the eccentric block of the frog-leaping rammer is usually not adjustable. The non-adjustable eccentric block means that the vibration frequency and vibration force it generates are fixed, which limits the adaptability of the rammer to different soil types or different construction requirements. For some operations that require higher or lower vibration forces, the fixed eccentric block may not be able to achieve the ideal compaction effect, and its versatility is low. Utility Model Content

[0005] The purpose of the utility model is to provide a ground compacting device for construction, which has the advantage of an adjustable center of gravity of an eccentric block, and solves the problem that the center of gravity of the eccentric block of a leapfrog rammer cannot be adjusted, and the vibration frequency and vibration force generated are fixed, which limits the adaptability of the rammer under different soil types or different construction requirements and the problem of low versatility.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ground compacting device for construction, comprising a main body mechanism, a compacting mechanism is fixedly installed on one side of the main body mechanism, the compacting mechanism comprises a first mounting frame, a rotating shaft is rotatably installed on the top of the first mounting frame, a second mounting frame is rotatably installed on the outer wall of the rotating shaft, a third pulley is fixedly installed on the outer wall of the rotating shaft, a second transmission belt is sleeved on the outer wall of the third pulley, a fourth pulley is rotatably installed inside the second mounting frame, the second transmission belt is sleeved on the outer wall of the fourth pulley, eccentric blocks are fixedly installed on the left and right sides of the fourth pulley, a tamping plate is movably installed on the bottom of the second mounting frame, a screw is fixedly installed inside the eccentric block, an adjusting block is threadedly connected to the outer wall of the screw, and the adjusting block is slidably installed inside the eccentric block.

[0007] As a preferred embodiment of the ground compacting device for construction of the utility model, an adjusting knob is rotatably mounted on one side of the eccentric block, and the adjusting knob is fixedly connected to one side of the screw rod.

[0008] As a preferred embodiment of the ground compacting device for construction of the utility model, the compacting mechanism further comprises a plurality of springs, and the springs are arranged between the tamping plate and the second mounting frame.

[0009] As a preferred ground compacting device for construction of the utility model, a plurality of slide grooves are provided on the top of the tamping plate, a plurality of limit bolts are fixedly mounted on one side of the second mounting frame, and the limit bolts are slidably mounted inside the slide grooves.

[0010] As a preferred embodiment of the ground compacting device for construction of the utility model, a plurality of protruding columns are fixedly mounted on the bottom of the tamping plate.

[0011] As a preferred ground compacting device for construction of the utility model, the main body mechanism includes a tray, a control frame is rotatably mounted on the top of the tray, non-slip handles are fixedly mounted on the left and right sides of the control frame, and a control box is fixedly mounted on the top of the control frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model makes the fourth pulley rotate along with the rotating shaft through the cooperation among the third pulley, the second transmission belt and the fourth pulley, so that the rotating shaft drives the eccentric block to rotate. When the eccentric block rotates, periodic centrifugal force is generated. This force makes the tamping plate device vibrate up and down to compact the ground. At the same time, the center of gravity of the eccentric block is changed by rotating the screw to change the position of the adjusting block inside the eccentric block. The utility model has the advantage that the center of gravity of the eccentric block can be adjusted, which solves the problem that the center of gravity of the eccentric block of the frog leaping rammer cannot be adjusted, and the vibration frequency and vibration force generated are fixed, which limits the adaptability of the rammer under different soil types or different construction requirements and the problem of low versatility.

DETAILED DESCRIPTION

[0020] See also Figure 1-4A ground compacting device for construction, comprising a main body mechanism 1, a compacting mechanism 2 is fixedly installed on one side of the main body mechanism 1, the compacting mechanism 2 comprises a first mounting frame 201, a rotating shaft 202 is rotatably installed on the top of the first mounting frame 201, a second mounting frame 203 is rotatably installed on the outer wall of the rotating shaft 202, a third pulley 204 is fixedly installed on the outer wall of the rotating shaft 202, a second transmission belt 205 is sleeved and installed on the outer wall of the third pulley 204, a fourth pulley 206 is rotatably installed inside the second mounting frame 203, the second transmission belt 205 is sleeved and installed on the outer wall of the fourth pulley 206, eccentric blocks 207 are fixedly installed on the left and right sides of the fourth pulley 206, a tamping plate 211 is movably installed on the bottom of the second mounting frame 203, a screw rod 208 is fixedly installed inside the eccentric block 207, an adjusting block 209 is threadedly connected to the outer wall of the screw rod 208, and the adjusting block 209 is slidably installed inside the eccentric block 207;

[0021] During use, the third pulley 204, the second transmission belt 205 and the fourth pulley 206 cooperate to make the fourth pulley 206 rotate with the rotating shaft 202, and then the rotating shaft 202 drives the eccentric block 207 to rotate. When the eccentric block 207 rotates, a periodic centrifugal force is generated. This force causes the ramming plate 211 device to vibrate up and down to compact the ground. At the same time, the position of the adjusting block 209 inside the eccentric block 207 is changed by rotating the screw 208, so as to change the center of gravity of the eccentric block 207. The advantage of having an adjustable center of gravity of the eccentric block 207 is that the center of gravity of the leapfrog rammer 207 cannot be adjusted, and the vibration frequency and vibration force generated are fixed, which limits the adaptability of the rammer to different soil types or different construction requirements, and the problem of low versatility.

[0022] Furthermore, an adjusting knob 210 is rotatably mounted on one side of the eccentric block 207, and the adjusting knob 210 is fixedly connected to one side of the screw rod 208;

[0023] During use, the user can rotate the screw rod 208 by adjusting the knob 210 .

[0024] Furthermore, the tamping mechanism 2 further includes a plurality of springs 212, and the springs 212 are arranged between the tamping plate 211 and the second mounting frame 203;

[0025] During use, the elastic deformation of the spring 212 can allow the ramming head to have a certain "give-way" space when encountering hard objects or uneven ground, avoiding the ramming head from jumping or the machine from losing control due to hard impact, making the ramming process smoother and the operation easier to control.

[0026] Furthermore, a plurality of slide grooves 213 are provided on the top of the tamping plate 211, and a plurality of stop bolts 214 are fixedly installed on one side of the second mounting frame 203, and the stop bolts 214 are slidably installed inside the slide grooves 213;

[0027] During use, the displacement distance of the ramming plate 211 at the bottom of the second mounting bracket 203 is limited by the cooperation between the sliding groove 213 and the limiting bolt 214, thereby preventing the spring 212 from being damaged due to excessive deformation.

[0028] Furthermore, a plurality of bosses 215 are fixedly mounted on the bottom of the tamping plate 211;

[0029] During use, a number of protruding columns 215 can generate local high pressure when tamping the ground. This concentrated pressure helps to penetrate deep into the soil, break up large soil particles, make the soil more compact, and thus improve the overall compactness and uniformity.

[0030] Furthermore, the main body mechanism 1 includes a tray 101, a control frame 102 is rotatably mounted on the top of the tray 101, non-slip grips 103 are fixedly mounted on both the left and right sides of the control frame 102, and a control box 104 is fixedly mounted on the top of the control frame 102;

[0031] During use, the tray 101 provides a support point for the operator to facilitate controlling and moving the machine, and the direction and travel speed of the machine are controlled through the coordinated operation between the control frame 102 and the anti-slip handle 103, and the start, stop and direction adjustment of the rammer are controlled through the control box 104.

[0032] Further, a motor 105 is fixedly installed on the top of the tray 101, and a first pulley 106 is fixedly connected to one side of the motor 105 through a coupling, and a first transmission belt 107 is sleeved and installed on the outer wall of the first pulley 106, and a second pulley 108 is fixedly installed on one side of the rotating shaft 202, and the first transmission belt 107 is sleeved and installed on the outer wall of the second pulley 108, and a counterweight 109 is fixedly installed on the top of the tray 101;

[0033] During use, the motor 105, the first pulley 106, the first transmission belt 107, and the second pulley 108 cooperate to provide power for the rotation of the rotating shaft 202, and the counterweight block 109 increases the deadweight of the main mechanism 1 to increase the stability of the equipment during operation.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
