Description

Technical Field

[0001] This application relates to the technical field of foundation compaction devices, and in particular to a foundation compaction device for building engineering. Background Technology

[0002] With technological advancements, some simple mechanical compaction equipment began to emerge, such as early rudimentary compactors. These machines used simple mechanical structures to move the compaction seat up and down, but they were mostly fixed in frequency and force, unable to adapt to complex and varied foundation conditions. Furthermore, these machines were mostly stationary, making them difficult to move easily between different construction sites and exhibiting extremely poor adaptability to different terrains. In terms of mobility, older equipment lacked specially designed mobile vehicles; changing construction sites often required significant manpower and resources for transporting and reassembling, greatly impacting construction progress.

[0003] Regarding the aforementioned technologies, it has been found that existing foundation compaction equipment cannot adjust the lifting stroke of the movable frame according to actual construction needs, limiting the equipment's flexibility in different scenarios. Furthermore, during the compaction process, traditional equipment lacks effective limiting and buffering structures, causing the enormous impact force generated by the compaction seat to act directly on the equipment itself. This not only easily damages the equipment and shortens its lifespan but also affects the compaction strength of the compaction seat due to the dispersed impact force, making it difficult to guarantee the compaction quality of the foundation. Utility Model Content

A movable frame is provided at the front end of the equipment support, and the movable frame is slidably connected to the equipment support. A rotary arm is also provided on the upper end face of the equipment support to drive the movable frame to reciprocate and lift. The rotary arm is rotatably connected to the equipment support, and a motor that drives the rotary arm to rotate is fixedly installed on the equipment support. A compaction box assembly is fixedly installed on the movable frame. A compaction seat is slidably installed on the lower end face of the compaction box assembly, and the compaction seat is slidably connected to the compaction box assembly. A pressure cover assembly that limits the compaction seat is also fixedly installed on the upper end face of the compaction box assembly.

[0006] By adopting the above technical solution, the mobile vehicle body provides mobility for the entire compaction device, facilitating its transfer between different construction sites and improving the device's flexibility and applicability. A chassis with good off-road performance, such as certain Caterpillar chassis models, can be selected as the mobile vehicle body. These chassis have strong load-bearing capacity and can adapt to different terrain conditions. The base plate of the equipment support provides a stable support foundation for the entire device. The movable frame drives the compaction box assembly and compaction seat to perform compaction operations through lifting and lowering. The motor and swing arm are used to drive the movable frame to reciprocate up and down. The compaction box assembly provides a stable frame structure for the sliding of the compaction seat, ensuring the stability and accuracy of the compaction seat during lifting and lowering. The pressure-holding cover assembly limits the movement of the compaction seat on the compaction box assembly, ensuring that the compaction seat can stably perform the compaction operation.

[0007] Optionally, the equipment support includes a base plate, a bracket, and a guide rod for mounting the movable frame. The bracket is fixedly installed in the middle of the upper surface of the base plate, and the guide rod is vertically installed on the upper surface of the base plate and fixedly connected to the base plate.

[0009] Optionally, the movable frame includes a frame and a horizontal guide rail seat, the horizontal guide rail seat being installed on one side of the frame and fixedly connected to the frame.

[0010] By adopting the above technical solution, the frame of the movable frame is used to install the compaction box assembly. The horizontal guide rail seat cooperates with the rotating arm of the slewing arm, enabling the movable frame to achieve stable reciprocating lifting and lowering motion under the drive of the slewing arm, thereby driving the compaction seat to compact the foundation.

[0011] Optionally, the boom arm includes a main boom housing, an extension boom, and a rotating arm. One end of the main boom housing is connected to the output end of the motor. The extension boom is slidably mounted on the other end of the main boom housing. The rotating arm is mounted on the outer end of the extension boom and is rotatably connected to the extension boom.

[0012] By adopting the above technical solution, the main boom housing, extension boom, and rotating arm of the slewing boom work together. The main boom housing is driven to rotate by a motor, the extension boom can be adjusted in length as needed, and the rotating arm slides into the horizontal guide rail seat of the mobile frame to achieve the lifting and lowering of the mobile frame. This structural design allows the lifting stroke and speed of the mobile frame to be adjusted according to actual needs, improving the flexibility and efficiency of compaction operations.

[0013] Optionally, the main boom housing includes a connecting sleeve and a sleeve for sliding installation of the extension boom. The sleeve is installed on one side of the connecting sleeve and is integrally formed with the connecting sleeve. The sleeve has a connecting hole, and the extension boom has several mating holes corresponding to the connecting hole. The extension boom is fixed to the sleeve by bolts.

[0014] By adopting the above technical solution, the main boom shell is designed with a structure in which a connecting sleeve and a sleeve cooperate. When needed, it can be connected to the motor output shaft through the connecting sleeve, so that the motor can drive the main boom shell to rotate stably during use. The sleeve allows the boom to slide and adjust its length as needed. Then, it can be locked by installing bolts in the connecting hole and the mating hole.

[0015] Optionally, the rotating arm includes a rotating shaft and a movable slider that slides with a horizontal guide rail seat. One end of the rotating shaft is rotatably mounted on the extension arm, and the movable slider is fixedly mounted on the other end of the rotating shaft.

[0016] By adopting the above technical solution, the rotating arm is designed with a structure in which the rotating shaft and the movable slider cooperate. When needed, it can be slidably installed in the horizontal guide rail seat through the movable slider. In this way, when the rotating arm rotates, the horizontal guide rail seat can be driven to move up and down reciprocally through the rotating arm.

[0017] Optionally, the compaction seat includes a seat block, a slide rod seat, and a base plate. The slide rod seat is slidably mounted on the compaction box assembly, the seat block is fixedly mounted on the lower end of the slide rod seat, and the base plate is fixedly mounted on the lower end face of the slide rod seat.

[0018] By adopting the above technical solution, the seat block, sliding rod seat and base plate of the compaction seat cooperate with each other, the sliding rod seat slides on the compaction box assembly, and the seat block and base plate directly contact the foundation, transferring the compaction energy to the foundation.

A support spring is placed in the tube shell.

[0020] By adopting the above technical solution, the top cover and pressure rod of the pressure-holding assembly cooperate with the shell and support spring of the compaction seat to limit and buffer the compaction seat. During the upward movement of the compaction seat, the support spring is compressed and stores energy. During the downward movement of the compaction seat, the support spring releases energy, increasing the compaction force of the compaction seat while reducing the impact force on the device during the compaction process.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This application achieves automated compaction operations by using a motor-driven rotary arm to move the movable frame and compaction seat in a reciprocating lifting motion, greatly improving compaction efficiency and reducing manual labor intensity. Simultaneously, the motor's speed regulation function and the adjustable length of the rotary arm allow for easy adjustment of the compaction frequency and force according to different foundation soil types and compaction requirements, improving the flexibility of compaction. The mobile vehicle allows the device to be easily moved between different construction sites, suitable for various terrain conditions. The adjustable length of the rotary arm extension allows for adjustment of the lifting stroke of the movable frame according to actual construction needs, improving the device's operational flexibility. The limiting and buffering function of the pressure-holding cover group reduces the impact force on the device during compaction, while increasing the compaction force of the compaction seat, ensuring the quality of foundation compaction.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a foundation compaction device for building engineering. (Refer to...) Figure 1 , Figure 2 and Figure 3 As shown, a foundation compaction device for building construction includes a mobile vehicle body 1. An equipment support 2 is fixedly installed on the mobile vehicle body 1. A movable frame 3 is provided at the front end of the equipment support 2, and the movable frame 3 is slidably connected to the equipment support 2. A rotary arm 4, which drives the movable frame 3 to reciprocate, is also provided on the upper surface of the equipment support 2. The rotary arm 4 is rotatably connected to the equipment support 2, and a motor 5, which drives the rotary arm 4 to rotate, is also fixedly installed on the equipment support 2. A compaction box assembly 8 is fixedly installed on the movable frame 3. A compaction seat 6 is slidably installed on the lower surface of the compaction box assembly 8, and the compaction seat 6 is slidably connected to the compaction box assembly 8. A pressure cover assembly 7, which limits the compaction seat 6, is also fixedly installed on the upper surface of the compaction box assembly 8. The mobile vehicle body 1 provides mobility for the entire compaction device, facilitating its transfer between different construction sites and improving the device's flexibility and applicability. A chassis with good off-road performance can be selected as the mobile body 1, such as certain Caterpillar chassis models. These chassis have strong load-bearing capacity and can adapt to different terrain conditions. The base plate 21 of the equipment support 2 provides a stable support foundation for the entire device. The movable frame 3 drives the compaction box assembly 8 and the compaction seat 6 to perform compaction operations through lifting and lowering. The purpose of driving the movable frame 3 to reciprocate up and down is achieved through the setting of the motor 5 and the rotating arm 4. The motor 5, as the power source for driving the rotation of the rotating arm 4, can be a three-phase asynchronous motor with speed regulation function, such as the YVF2 series variable frequency speed control motor 5. This series of motors 5 has a wide speed regulation range and can precisely adjust the rotation speed of the rotating arm 4 according to different compaction requirements, thereby controlling the lifting frequency of the movable frame 3 and the compaction force of the compaction seat 6. The compaction box assembly 8 provides a stable frame structure for the sliding of the compaction seat 6, ensuring the stability and accuracy of the compaction seat 6 during the lifting and lowering process. The compaction box assembly 8 can be made of cast steel, such as ZG270-500 cast steel, which has high strength and toughness and can withstand the impact force during the compaction process. The compaction seat 6 on the compaction box assembly 8 is limited by the pressure-holding cover assembly 7 to ensure that the compaction seat 6 can carry out the compaction operation stably.

[0031] Reference Figure 1As shown, the equipment support 2 includes a base plate 21, a bracket 22, and a guide rod 23 for mounting the movable frame 3. The bracket 22 is fixedly installed in the middle of the upper surface of the base plate 21, and the guide rod 23 is vertically installed on the upper surface of the base plate 21 and fixedly connected to the base plate 21. By designing the equipment support 2 as a structure in which the base plate 21, bracket 22, and guide rod 23 cooperate, the bracket 22 is used to install and fix other components during use, and the guide rod 23 provides precise guidance for the lifting and lowering of the movable frame 3, ensuring the stability and accuracy of the movement of the movable frame 3. The base plate 21 can be made of high-strength steel plate, such as Q345 steel plate, which has good strength and toughness; the guide rod 23 can be made of 45 steel, which has been quenched and tempered to improve its hardness and wear resistance.

[0032] Reference Figure 2 As shown, the movable frame 3 includes a frame 31 and a horizontal guide rail seat 32. The horizontal guide rail seat 32 is installed on one side of the frame 31 and is fixedly connected to the frame 31. The frame 31 of the movable frame 3 is used to install the compaction box assembly 8. The horizontal guide rail seat 32 cooperates with the rotating arm 43 of the slewing arm 4, enabling the movable frame 3 to achieve stable reciprocating lifting and lowering motion under the drive of the slewing arm 4, thereby driving the compaction seat 6 to perform compaction work on the foundation.

[0033] Reference Figure 5 and Figure 6As shown, the slewing boom 4 includes a main boom housing 41, an extension boom 42, and a rotating arm 43. One end of the main boom housing 41 is connected to the output end of the motor 5. The extension boom 42 is slidably mounted on the other end of the main boom housing 41. The rotating arm 43 is mounted on the outer end of the extension boom 42 and is rotatably connected to the extension boom 42. The main boom housing 41, extension boom 42, and rotating arm 43 of the slewing boom 4 cooperate with each other. The motor 5 drives the main boom housing 41 to rotate. The length of the extension boom 42 can be adjusted as needed. The rotating arm 43 is slidably engaged with the horizontal guide rail seat 32 of the movable frame 3, realizing the lifting and lowering of the movable frame 3. This structural design allows the lifting stroke and speed of the movable frame 3 to be adjusted according to actual needs, improving the flexibility and efficiency of compaction operations. The main boom housing 41 includes a connecting sleeve 411 and a sleeve 412 for sliding installation of the extension boom 42. The sleeve 412 is installed on one side of the connecting sleeve 411 and is integrally formed with the connecting sleeve 411. The sleeve 412 has a connecting hole 413, and the extension boom 42 has several mating holes 421 corresponding to the connecting hole 413. The extension boom 42 is fixed to the sleeve 412 by bolts. By designing the main boom housing 41 with a structure in which the connecting sleeve 411 and the sleeve 412 mate, it is convenient to connect to the output shaft of the motor 5 through the connecting sleeve 411 when needed, so that the motor 5 can drive the main boom housing 41 to rotate stably during use. The sleeve 412 allows the boom 43 to slide flexibly to adjust its length as needed, and then it can be locked by installing bolts in the connecting hole 413 and the mating hole 421. The rotating arm 43 includes a rotating shaft 431 and a movable slider 432 that slides with the horizontal guide rail 32. One end of the rotating shaft 431 is rotatably mounted on the extension arm 42, and the movable slider 432 is fixedly mounted on the other end of the rotating shaft 431. By designing the rotating arm 43 with the rotating shaft 431 and the movable slider 432 in a cooperating structure, it is convenient to slide the movable slider 432 into the horizontal guide rail 32 when needed. Thus, when the rotating arm 4 rotates, the rotating arm 43 can drive the horizontal guide rail 32 to reciprocate up and down.

[0034] Reference Figure 2 and Figure 3 As shown, the compaction seat 6 includes a seat block 61, a sliding rod seat 62, and a base plate 63.

The seat block 61, sliding rod seat 62, and base plate 63 of the compaction seat 6 cooperate with each other. The sliding rod seat 62 slides on the compaction box assembly 8, while the seat block 61 and base plate 63 are in direct contact with the foundation, transferring compaction energy to the foundation. The seat block 61 and base plate 63 can be made of high-strength wear-resistant alloy steel, such as ZGMn13 high manganese steel, which has good wear resistance and impact resistance, and can maintain good working condition during long-term compaction operations.

[0035] Reference Figure 1 and Figure 4 As shown, the pressure-holding cover assembly 7 includes a top cover 71 and a pressure-holding rod 72.

The upper end face of the sliding rod seat 62 is provided with a tube shell 621 that cooperates with the pressure-holding rod 72, and a support spring 622 is placed in the tube shell 621. The top cover 71 and the pressure-holding rod 72 of the pressure-holding cover assembly 7 cooperate with the tube shell 621 and the support spring 622 of the compaction seat 6, which play a role in limiting and buffering the compaction seat 6. During the rising process of the compaction seat 6, the support spring 622 is compressed and stores energy. During the falling process of the compaction seat 6, the support spring 622 releases energy, increasing the compaction force of the compaction seat 6, while reducing the impact force on the device during the compaction process. The top cover 71 can be made of steel plate, the pressure-holding rod 72 can be made of 45# steel, and the support spring 622 can be made of 60Si2Mn spring steel, which has good elasticity and fatigue life.
