Description

Technical Field

[0001] This application relates to the field of building foundation construction, and in particular to a type of machinery for foundation engineering construction. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, when necessary, admixtures and additives in a certain proportion, uniformly stirring, compacting, and curing. Concrete has the advantages of abundant raw materials, low price, and simple production process, which has led to its increasing use.

[0003] A pile foundation is a deep foundation consisting of piles and a pile cap composed of interlaced piles and pile reinforcement connecting the pile tops, or a single pile foundation consisting of columns connected to the pile foundation. When making pile foundations, it is usually necessary to dig a foundation pit on the ground, then pour concrete into the foundation pit and let it solidify to complete the construction of the pile foundation.

[0004] When pouring concrete into a foundation pit, the concrete needs to be vibrated to remove air and increase its strength. This process typically involves manually setting up a tremie pipe, through which workers pour the concrete into the pit. Once the concrete has reached a certain height, pouring is stopped, and workers then move the vibrator pipe deeper into the pit to continue vibrating. This process is repeated, which not only affects the efficiency of concrete pouring but also increases the labor intensity for workers. Summary of the Invention

[0005] In order to improve the construction efficiency of concrete pile foundations, the purpose of this application is to provide a construction machinery for foundation engineering.

[0006] The foundation engineering construction machinery provided in this application adopts the following technical solution: A foundation engineering construction machine includes a vehicle body and a material hopper for holding concrete. The material hopper is mounted on the vehicle body. The vehicle body is provided with a discharge hose for discharging concrete. A connecting pipe for adding concrete to the discharge hose is provided between the material hopper and the discharge hose. A drive mechanism for driving the discharge hose to lower or raise is installed on the vehicle body. A vibrator is installed on the vehicle body. A vibrating pipe is fixedly connected to and connected to the vibrator. The vibrating pipe is arranged along the length of the discharge hose. The end of the vibrating pipe away from the vibrator is connected to the discharge end of the discharge hose. A first transmission assembly for retrieving or lowering the vibrating pipe is installed on the vehicle body.

[0007] By adopting the above technical solution, when concrete needs to be poured in the foundation pit, the vehicle body is moved above the foundation pit, and then the drive mechanism is controlled simultaneously to move the vibrating pipe and the discharge hose into the foundation pit. When the vibrating pipe and the discharge hose reach the appropriate position in the foundation pit, concrete is added to the material hopper, allowing the concrete to enter the discharge hose through the connecting pipe and finally into the foundation pit. Then, the drive mechanism and the first transmission component are controlled simultaneously to move the vibrating pipe and the discharge hose upwards, and the vibrator is activated to vibrate the concrete through the vibrating pipe. This allows the vibrating pipe and the discharge hose to move simultaneously and vibrate the concrete during the addition process in the foundation pit, eliminating the need to repeatedly control the movement of the vibrating pipe and the discharge hose. This saves time in pouring concrete in the foundation pit and improves the construction efficiency of concrete foundation piles.

[0008] Optionally, the feeding hose includes a main feeding section and a sealing section, which are detachably connected. The driving mechanism includes a second transmission component for controlling the movement of the main feeding section and a third transmission component for controlling the movement of the sealing section. The feeding hose is positioned between the second transmission component and the third transmission component. The driving mechanism also includes a mounting plate mounted on the vehicle body. Two parallel driving screws are threadedly connected to the mounting plate. The lower end of each driving screw is rotatably connected to the end of the discharge end of the sealing section. A first servo motor for driving the screws to rotate is mounted on the mounting plate. A driven gear is rotatably connected to the mounting plate. The driving screw and the driven gear are coaxially arranged and threadedly connected. A drive gear is fixedly connected to the end of the first servo motor, and the drive gear meshes with the driven gear.

[0009] By adopting the above technical solution, the first servo motor can be started, causing it to rotate via a drive gear. This causes a drive screw threadedly connected to the drive gear to move along its own axis. Consequently, the feed hose connected to the drive screw moves up and down with it, allowing for rapid control of the feed hose's lowering and raising via the first servo motor. Simultaneously, during the raising of the feed hose, the second transmission component lifts the main feed pipe, and the third transmission component lifts the sealing section, causing them to move and separate to opposite sides. This separation of the feed section and sealing section during the raising process allows concrete to be directly added into the main feed section. This reduces the distance the concrete travels within the feed hose, decreases the workload of workers moving the hose, improves efficiency during both lowering and raising, facilitates collection of the feed hose, reduces concrete accumulation, and allows for easy cleaning of the feed hose's interior after separation.

[0010] Optionally, a first magnet block is fixedly connected to the side of the main feeding part near the sealing part, and a second magnet block is fixedly connected to the sealing part. The first magnet block and the second magnet block attract each other at one end, and the main feeding part and the sealing part are detachably connected through the first magnet block and the second magnet block.

[0011] By adopting the above technical solution, when the discharge hose is lowered, the main discharge section and the sealing section, which are separate from each other, can be automatically combined into a discharge hose by the mutual attraction of the first magnet block and the second magnet block, and the flow direction of concrete in the foundation pile can be limited. At the same time, the first magnet block and the second magnet block attract each other.

[0012] Optionally, the first transmission component includes a second servo motor, on which a winding shaft is fixedly connected, and the middle section of the vibrating pipe is wound around the winding shaft.

[0013] By adopting the above technical solution, the second servo motor can be started to drive the winding shaft to rotate, thereby allowing the vibrating tube to be wound on the winding shaft and lifted, or the vibrating tube to be detached from the winding shaft and lowered. Thus, by controlling the second servo motor, the vibrating tube can be moved synchronously with the adjusting screw.

[0014] Optionally, the second transmission assembly includes a first take-up roller, which is rotatably connected to the vehicle body. A third servo motor for driving the first take-up roller to rotate is mounted on the vehicle body. The third servo motor is fixedly connected to the first take-up roller, and the feed end of the main unloading section is fixedly connected to the arc-shaped sidewall of the first take-up roller.

[0015] By adopting the above technical solution, the first take-up roller can be rotated by the third servo motor, so that the main unloading part can be wound around or unwound from the first take-up roller, thereby flexibly lifting or lowering the main unloading part.

[0016] Optionally, the third transmission assembly includes a second take-up roller, which is rotatably connected to the vehicle body. A fourth servo motor for driving the second take-up roller to rotate is mounted on the vehicle body. The fourth servo motor is fixedly connected to the second take-up roller, and the feed end of the sealing part is fixedly connected to the arc-shaped sidewall of the second take-up roller.

[0017] By adopting the above technical solution, the second take-up roller can be rotated by the fourth servo motor, so that the sealing part can be wrapped around or detached from the first take-up roller, thereby flexibly lifting or lowering the sealing part.

[0018] Optionally, cams are fixedly connected to the lower ends of both drive screws, and the rotation axes of the cams coincide with those of the drive screws. An abutment block for abutting against the cams is fixedly connected to the arc-shaped sidewall of the end of the vibrating pipe. The abutment block is placed between the two cams. When the two cams rotate, the cams abut against the abutment blocks in sequence. A sliding groove perpendicular to the length direction of the sealing part is opened on the sidewall of the sealing part. A connecting block is fixedly connected to the sidewall of the vibrating pipe, and the connecting block is slidably connected in the sliding groove.

[0019] By adopting the above technical solution, when the drive bolt rotates, the cam can rotate together with the drive screw, and the two cams can abut against the abutment block in sequence, thereby causing the end of the vibrating pipe to slide in the groove on the sealing part along the direction perpendicular to the length of the sealing part. This can increase the vibration range of the vibrating pipe and improve the vibration effect on the concrete.

[0020] Optionally, a recovery hopper is installed on the vehicle body, and the recovery hopper is positioned below the first take-up roller.

[0021] By adopting the above technical solution, when the first take-up roller takes up the wire, the concrete remaining in the main discharge section of the discharge hose can fall into the recycling hopper for centralized recycling, thereby reducing concrete waste.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. It allows the vibrating pipe and the feeding hose to move simultaneously and vibrate the concrete during the addition process in the foundation pit. It eliminates the need to repeatedly control the movement of the vibrating pipe and the feeding pipe, thereby saving time in pouring concrete in the foundation pit and improving the construction efficiency of concrete foundation piles. 2. The vibratory tube can be wound around the winding shaft to lift the vibratory tube, or the vibratory tube can be detached from the winding shaft and lowered. This can be achieved by controlling the second servo motor, which drives the vibratory tube to move synchronously with the adjusting screw. 3. When the drive bolt rotates, the cam can rotate together with the drive screw, and the two cams can abut against the abutment block in sequence, thereby causing the end of the vibrating pipe to slide in the groove on the sealing part along the length direction perpendicular to the sealing part. This can increase the vibration range of the vibrating pipe and improve the vibration effect on the concrete. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0025] An embodiment of this application is: a foundation engineering construction machinery, referring to... Figure 1 and Figure 2 The vehicle includes a rectangular body 1, a material hopper 2 for holding concrete is mounted and fixedly connected on the top of the vehicle body 1, the upper end of the material hopper 2 is open, a connecting pipe 21 is provided below the material hopper 2, the connecting pipe 21 is fixed to the vehicle body 1, one end of the connecting pipe 21 is fixedly connected to and communicates with the lower end of the material hopper 2, and a discharge hose 3 is provided at the end of the connecting pipe 21 away from the discharge hopper. A drive mechanism 4 for controlling the lowering or raising of the discharge hose 3 is installed on the vehicle body 1.

[0026] Reference Figure 1 , Figure 2 and Figure 3The vehicle body 1 includes two first support rods 13 fixedly connected to itself. The first support rods 13 are located at the end of the vehicle body 1 away from the material hopper 2, and the end of the first support rod 13 away from the vehicle body 1 extends upward towards the upper side of the vehicle body 1. The drive mechanism 4 includes a mounting plate 44. The ends of the two first support rods 13 away from the vehicle body 1 are fixedly connected to the bottom surface of the same mounting plate 44. The mounting plate 44 is arranged parallel to the upper surface of the vehicle body 1. An identical mounting plate 44 is provided above the mounting plate 44. Four second support rods 14 for connecting the two mounting plates 44 are fixedly connected between them, and the second support rods 14 are respectively located at the four corners of the mounting plate 44.

[0027] The drive mechanism 4 also includes a drive screw 45 threadedly connected to the mounting plate 44. The drive screw 45 passes through the two mounting plates 44, and the axes of the two drive screws 45 are parallel to each other. The axis of the drive screw 45 is perpendicular to the end face of the mounting plate 44. Two mounting posts 441 are provided between the two mounting plates 44. The drive screw 45 corresponds to the mounting post 441 one by one, and the drive screw 45 passes through the mounting post 441 and is slidably connected to the mounting post 441. The drive screw 45 and the mounting post 441 are coaxially arranged. The lower end of the mounting post 441 is fixedly connected to the lowermost mounting plate 44 of the two mounting plates 44. The upper end of the mounting post 441 is rotatably connected to a driven gear 48. The driven gear 48 is coaxially arranged with the drive screw 45, and the drive screw 45 passes through the driven gear 48 and is threadedly connected to the driven gear 48. A drive gear 47 is provided on one side of the driven gear 48. Two drive gears 47 are placed between two driven gears 48. The driven gears 48 mesh with the drive gears 47. A first servo motor 46 is provided below the drive gear 47. The first servo motor 46 is fixedly connected to the mounting plate 44. The output shaft of the first servo motor 46 is coaxially set and fixedly connected to the drive gear 47.

[0028] This activates the first servo motor 46, which drives the drive gear 47 to rotate. As a result, the drive gear 47, which meshes with the drive gear 47, will rotate simultaneously, and the drive screw 45, which is threadedly connected to the drive gear 47, will move up and down along the axis of the drive screw 45.

[0029] A vibratory tube 5 is provided on the upper mounting plate 44 of the two mounting plates 44. One end of the vibratory tube 5 passes through both mounting plates 44 and is placed inside the material feeding hose 3. The other end of the vibratory tube 5 is used to connect to a vibrator, which is not shown in the figure. The drive mechanism 4 also includes a first transmission assembly 41 mounted on the mounting plate 44. The first transmission assembly 41 includes a winding shaft 412 rotatably connected to the mounting plate 44. A second servo motor 411 is mounted on the mounting plate 44. The output shaft of the second servo motor 411 is coaxially arranged with and fixedly connected to the winding shaft 412. The vibratory tube 5 is wound on the winding shaft 412.

[0030] This activates the second servo motor 411, which drives the winding shaft 412 to rotate, thereby causing the vibrating tube 5 to wrap around the winding shaft 412 or to detach the vibrating tube 5 from the winding shaft 412 and lower it along the feeding hose 3.

[0031] The feeding hose 3 includes a main feeding section 31 and a sealing section 32. The main feeding section 31 is located on the side of the feeding hose 3 closer to the vehicle body 1. The vehicle body 1 includes a support frame 12 fixedly connected to itself. The drive mechanism 4 also includes a second transmission assembly 42 and a third transmission assembly 43 mounted on the support frame 12. The second transmission assembly 42 is located on the side of the support frame 12 closer to the material hopper 2, and the third transmission assembly 43 is located on the side of the support frame 12 away from the material hopper 2.

[0032] The second transmission assembly 42 includes a third servo motor 422 mounted on a support frame 12. A first take-up roller 421 is rotatably connected to the support frame 12. The output shaft of the third servo motor 422 is coaxially arranged and fixedly connected to the first take-up roller 421. The upper end of the main unloading part 31 is fixedly connected to the arc-shaped side wall of the first take-up roller 421.

[0033] The third transmission assembly 43 includes a fourth servo motor 432 mounted on a support frame 12. A second take-up roller 431 is rotatably connected to the support frame 12. The output shaft of the fourth servo motor 432 is coaxially arranged and fixedly connected to the second take-up roller 431. The upper end of the sealing part 32 is fixedly connected to the arc-shaped side wall of the second take-up roller 431.

[0034] Reference Figure 3 and Figure 4 Multiple first magnet blocks 311 are fixedly connected to both sides of the main feeding section 31 along its length. The first magnet blocks 311 are arranged along the length of the main feeding section 31 and are equidistant from each other along its length. Multiple second magnet blocks 321 are fixedly connected to both sides of the sealing section 32 along its length. The second magnet blocks 321 are arranged along the length of the sealing section 32 and are equidistant from each other along its length. The first magnet blocks 311 and the second magnet blocks 321 correspond one-to-one, and the first magnet blocks 311 and the second magnet blocks 321 attract and abut against each other.

[0035] This controls the rotation of the third servo motor 422 and the fourth servo motor 432, which can drive the main feeding part 31 and the sealing part 32 to lift or lower. At the same time, the second magnet block 321 on the sealing part 32 and the first magnet block 311 on the main feeding part 31 are released from their abutting state, causing the main feeding part 31 and the sealing part 32 to move to the side away from each other, or causing the first magnet block 311 and the second magnet block 321 to attract each other and causing the main feeding part 31 and the sealing part 32 to move to the side closer to each other.

[0036] Reference Figure 5 and Figure 6 The lower end of the drive screw 45 is rotatably connected to the side of the sealing part 32 facing the main feeding part 31, and the lower end of the drive screw 45 is placed outside the feeding hose 3. A cam 6 is fixedly connected to the lower end of the drive screw 45. The longest diameters on the end faces of the two cams 6 are perpendicular to each other. An abutment block 7 is fixedly connected to the lower end of the vibrating pipe 5. The vibrating pipe 5 passes through the abutment block 7 and communicates with the outside of the abutment block 7. A connecting block 8 is fixedly connected to the arc-shaped side wall of the vibrating pipe 5. A groove 322 is opened on the upper part of the sealing part 32 opposite to the connecting block 8. The groove 322 is set along the width direction of the sealing part 32. The end of the connecting block 8 away from the vibrating pipe 5 is slidably connected in the groove 322.

[0037] Therefore, when the drive screw 45 rotates, the cam 6 at the end of the drive screw 45 can rotate together with the drive screw 45. As a result, the ends of the two cams 6 will abut against the abutment block 7 in turn. As a result, the abutment block 7 will reciprocate along the opening direction parallel to the slide groove 322, thereby causing the end of the vibrating pipe 5 to reciprocate, thereby expanding the vibration range of the vibrating pipe 5.

[0038] Reference Figure 1 The end of the connecting pipe 21 away from the recycling hopper 11 is positioned above the first take-up roller 421, so that the concrete entering the connecting pipe 21 through the feed hopper can fall directly into the main discharge section 31 in the discharge hose 3. The recycling hopper 11 is fixedly connected to the vehicle body 1 and is positioned below the first take-up roller 421, so that when the main discharge section 31 is wrapped around the first take-up roller 421, the concrete remaining in the main discharge section 31 can fall into the recycling hopper 11 for centralized recycling.

[0039] The implementation principle of this application embodiment is as follows: When pouring concrete in the foundation pit, the vehicle body 1 is moved above the foundation pit. Then, the first servo motor 46 can be controlled to drive the drive screw 45 to rotate, thereby causing the drive screw 45 to lower the material discharge hose 3. At the same time, the second servo motor 411 is started, causing the winding shaft 412 to rotate and synchronously lower the vibrating pipe 5. Simultaneously, the third servo motor 422 and the fourth servo motor 432 need to be started. The third servo motor 422 drives the main material discharge part 31 to lower, and the fourth servo motor 432 drives the sealing part 32 to lower. During the lowering process, the main material discharge part 31 and the sealing part 32 will combine under the mutual attraction of the first magnet block 311 and the second magnet block 321 to form a lower... The material hose 3 is then used. When the vibrating pipe 5 and the material hose 3 reach the appropriate position in the foundation pit, concrete can be added to the material hopper 2, so that the concrete enters the material hose 3 through the connecting pipe 21 and finally enters the foundation pit. Then, a vibrator is set at the upper end of the vibrating pipe 5 and connected to the vibrating pipe 5. Then, the first servo motor 46, the second servo motor 411, the third servo motor 422 and the fourth servo motor 432 are controlled at the same time to make the drive screw 45, the vibrating pipe 5 and the material hose 3 move upward at the same time, and the vibrator is started so that the vibrator vibrates the concrete through the vibrating pipe 5. At the same time, during the upward movement of the drive screw 45, the vibrating pipe 5 will be driven to reciprocate under the action of the cam 6 and the abutment block 7, thereby expanding the vibration range of the vibrating pipe 5 on the concrete, until the grouting of the entire foundation pit is completed.
