Description

Technical Field

[0001] The utility model belongs to the technical field related to foundation construction, and particularly relates to a tamping and reinforcing device for foundation construction. Background Art

[0002] Ground compaction is a ground treatment method that applies external force to rearrange soil particles, reduce soil porosity, and increase soil density and bearing capacity. This method is usually used to improve foundation stability and reduce settlement. Ground compaction methods mainly include manual compaction and mechanical compaction. Common tools for manual compaction include wooden rammers and stone rammers, while mechanical compaction uses various types of rammers, internal combustion rammers, frog-type rammers and other equipment. The heavy hammer compaction method uses the impact force of the free fall of the heavy hammer to compact the soil. It is suitable for small-area backfill or environments with limited working surfaces. The surface compaction method uses tamping, vibration or rolling to make the soil layer at a certain depth on the surface reach a dense state. In the process of foundation compaction, it is necessary to use a compaction reinforcement device to carry out compaction construction, but it still has the following disadvantages in actual use:

[0003] When the foundation is being compacted, it is necessary to manually push the compaction reinforcement device to move and compact it. However, during the compaction process, the compacted structure is in direct contact with the ground, and the edges are exposed. During the pushing or pulling process, if the operator is not careful, the edges are likely to press on the feet of the on-site personnel, causing safety hazards;

[0004] When the foundation is being compacted, it is pushed directly by people. During operation, vibration is mainly generated by vibration equipment, which is transmitted to the foundation to compact the foundation. During the foundation compaction process, the vibration will be transmitted to the operator's hands by the compaction reinforcement device. When used for a long time, it will cause hand injuries to the operator and cause work injuries. Utility Model Content

[0009] Furthermore, a push handle is fixed to the rear portion of the top surface of the support platform, and a protective sleeve is fixed to the horizontal portion of the push handle. The support platform further performs hand shock absorption through the protective sleeve on the push handle.

[0010] Furthermore, two connecting plates are fixed on the inner wall of the vibration sleeve, a double-headed motor is fixed between the two connecting plates, and the vibration sleeve is connected to the double-headed motor via the connecting plates.

[0011] Furthermore, both output ends of the double-headed motor are fixed with a driving shaft, and the driving shaft is inserted into the connecting plate and extends out of the connecting plate. A counterweight is fixed to the lower part of the peripheral side of the position where the driving shaft extends out of the connecting plate.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0026] See also Figure 1-5 The utility model is a tamping and reinforcing device for foundation construction, comprising a support platform 1, a vibration sleeve 2, a connecting block 3 and a vibration plate 4. A through hole 103 is provided in the center of the support platform 1. The support platform 1 is movably provided with a fixing column 402 through the through hole 103, and the support platform 1 supports the connecting block 3 thereon through a compression spring 302, so that the vibration sleeve 2 is supported on the support platform 1. A vibration sleeve 2 is provided above the support platform 1, and a structure for generating impact tamping of the foundation is fixedly accommodated therein through the vibration sleeve 2. Two fixing columns 402 are fixed to the lower part of the peripheral side of the vibration sleeve 2, and the vibration sleeve 2 and the vibration plate 4 are connected by the fixing columns 402. The vibration sleeve 2 is connected, and when the vibration sleeve 2 is working, the vibration is transmitted to the vibration plate 4. The fixed column 402 is arranged in the through-hole 103. The bottom ends of the two fixed columns 402 are jointly fixed with the vibration plate 4. When the vibration sleeve 2 is working, the vibration is impacted by the vibration plate 4 to impact the foundation that needs to be reinforced and compact the foundation. Both ends of the vibration sleeve 2 are fixed with connecting blocks 3. The bottoms of the two connecting blocks 3 are fixed with compression springs 302. The connecting block 3 connects the compression spring 302 to its bottom and is supported on the support platform 1 through the compression spring 302, thereby reducing the vibration transmitted to the support platform 1 by the vibration sleeve 2. The bottom end of the compression spring 302 is fixed to the top of the support platform 1.

[0027] Specifically, support blocks 101 are fixed at the four corners of the bottom of the support platform 1, and each connecting block 3 is rotatably connected to a roller 102 on one side close to the center of the bottom of the support platform 1. When the support platform 1 is working, the roller 102 is connected to it through the support block 101, and supported by the roller 102 to roll on the working foundation to cooperate with the work of the support platform 1.

[0028] Furthermore, a push handle 104 is fixed to the rear of the top surface of the support platform 1, and a sheath 105 is fixed to the horizontal portion of the push handle 104. The support platform 1 is connected to the sheath 105 via the push handle 104, and the sheath 105 is further used for shock absorption to reduce the vibration transmitted to the operator's hand.

[0029] The operation process of this embodiment is: when the vibration sleeve 2 vibrates during operation, the connecting block 3 is driven to vibrate. When the connecting block 3 vibrates, the vibration is transmitted to the compression spring 302. The compression spring 302 reduces the vibration transmitted to the support platform 1, thereby reducing the vibration of the support platform 1 during operation. At the same time, when the operator holds the protective sleeve 105 and pushes the support platform 1, the impact of the vibration is further reduced through the protective sleeve 105, thereby increasing the safety of the operator's operation. Specific embodiment 2

[0030] See also Figure 1-5 On the basis of the specific embodiment 1, two connecting plates 201 are fixed on the inner wall of the vibration sleeve 2, and a double-headed motor 202 is fixed between the two connecting plates 201. The vibration sleeve 2 supports the double-headed motor 202 in the vibration sleeve 2 through the connecting plates 201.

[0031] Specifically, the two output ends of the double-headed motor 202 are fixed with a driving shaft 203, and the driving shaft 203 is inserted into the connecting plate 201 and extends out of the connecting plate 201. A counterweight 204 is fixed to the lower part of the peripheral side of the position where the driving shaft 203 extends out of the connecting plate 201. When the double-headed motor 202 is working, the driving shaft 203 is driven to rotate and drive the counterweight 204 to rotate. When the counterweight 204 rotates, vibration is generated. After the vibration is transmitted to the vibration sleeve 2, it is transmitted to the vibration plate 4 through the fixed column 402.

[0032] Furthermore, a telescopic rod 301 is fixed at the center of the bottom of the connection block 3 , and the bottom end of the telescopic rod 301 is fixed to the top of the support platform 1 . The connection block 3 limits the position of the connection block 3 through the telescopic rod 301 .

[0033] Furthermore, arc plates 401 are fixed at the lower edges of both sides of the vibration plate 4. The two arc plates 401 are symmetrical to each other. When the arc plates 401 move, they guide the uneven soil and stones on the foundation to the bottom of the vibration plate 4.

[0034] The operation process of this embodiment is: when working, when working, hold the protective cover 105, push the support platform 1, and then start the double-headed motor 202 in the vibration sleeve 2. When the double-headed motor 202 works, it drives the driving shaft 203 to rotate and drives the counterweight block 204 to rotate. When the counterweight block 204 rotates, vibration is generated. After the vibration is transmitted to the vibration sleeve 2, it is transmitted to the vibration plate 4 through the fixed column 402. The impact is transmitted to the foundation on the vibration plate 4 to compact the foundation. At the same time, by pushing the support platform 1, the vibration plate 4 is driven to move. When the arc plate 401 moves, the uneven soil layer and stones on the foundation are guided to the bottom of the vibration plate 4. When working, the vibration plate 4 is set at the bottom of the support platform 1, and the edge is at a certain distance from each edge of the bottom of the support platform 1, which increases the safety during construction, prevents the feet of people from being crushed during work, and increases work safety.
