Description

Technical Field

[0001] This utility model relates to the field of highway engineering technology, specifically a pile driver for highway engineering. Background Art

[0002] During highway construction, due to high urban land utilization and dense population, it is often necessary to accommodate more vehicles and pedestrians within a limited space. This places higher demands on the road's load-bearing capacity. Without reinforcement, the road may collapse or be damaged. Piling machines can firmly insert reinforced concrete piles into the ground, forming a strong support system, thereby enhancing the foundation's load-bearing capacity and preventing settlement and deformation.

[0003] For example, patent CN216043557U discloses a pile driver for highway engineering. The cylinder drives the lifting column and the movable column, which makes it easy to adjust the height of the drilling device and thus control the drilling depth. This allows the foundation pile to be placed in the hole without manual support, thereby avoiding danger to the operator.

[0004] However, while the device proposed in the aforementioned patent can control the drilling depth during road piling, it generates a large amount of dust during the drilling process, which has a significant impact on the surrounding environment. Furthermore, if there is a lot of debris in the drilling area, it is necessary to clean up the debris in advance, which increases the workload of the workers. At the same time, before piling, it is necessary to mark and mark the piling positions, and strictly control the distance between multiple holes. Only after marking and marking and cleaning up the debris can drilling and piling be carried out. The pre-piling operations are extremely cumbersome and affect the efficiency of piling. Therefore, we provide a piling machine for highway engineering to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a pile driver for highway engineering. This device can not only control the drilling depth, but also simultaneously reduce the dust generated during drilling. When the entire device is moved before pile driving, it can scrape the debris in the pile driving area to the outside. It can also display the distance when moving from the first pile driving point to the second point, without the need for manual marking and positioning beforehand.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pile driver for highway engineering, comprising a main board, a pile driving mechanism disposed on the upper part of the main board, the pile driving mechanism comprising a gantry frame fixed to the upper surface of the main board, and a through hole opened on the upper surface of the main board, the pile driving mechanism further comprising a lifting component connected to the inner top wall of the gantry frame, and a drilling component connected to the lifting component, the pile driving mechanism further comprising a display component connected to the gantry frame.

[0007] Support columns are fixedly connected to the four corners of the bottom surface of the motherboard, and casters are installed at the lower end of the support columns. A cleaning mechanism and a positioning mechanism are also provided on the upper part of the motherboard. The cleaning mechanism includes a scraping component and a dust reduction component located on the bottom surface of the motherboard.

[0008] Furthermore, the lifting assembly includes a first servo motor mounted on the upper surface of the main board, and a lead screw fixedly connected to the output shaft of the first servo motor and rotating in cooperation with the top wall inside the gantry frame. The outer surface of the lead screw is threaded with a lifting plate. By setting up the lifting assembly, the linkage between the first servo motor, the lead screw and the lifting plate in the lifting assembly can enable the lifting plate to drive the drilling assembly to move up and down, thereby controlling the drilling depth.

[0009] Furthermore, the lifting assembly also includes a fixing rod fixed to the inner top wall of the gantry frame and slidingly engaged with a pre-drilled hole on the upper surface of the lifting plate, and a fixing plate fixed to the lower end of the fixing rod and fixedly connected to the inner wall of the gantry frame. By setting the lifting assembly and the fixing rod inside the lifting assembly, the stability of the lifting plate during lifting movement can be improved, and the shaking of the lifting plate during lifting can be avoided, which would affect the drilling work of the drilling assembly.

[0010] Furthermore, the drilling assembly includes a second servo motor mounted on the upper surface of the lifting plate and slidingly engaged with a pre-drilled hole on the upper surface of the gantry frame. The output shaft of the second servo motor rotates through the lifting plate and is fixedly connected to a drill bit located directly above the through hole. By setting the drilling assembly, it is convenient to drill and drive piles into the ground, and by setting the drill bit, soil can be discharged upwards during drilling.

[0011] Furthermore, the display component includes a guide groove formed on the inner side wall of the gantry frame, and a pointer that slides with the guide groove and is connected to the lifting plate. A scale plate that matches the pointer is fixedly connected to the outer surface of the gantry frame. By setting the display component, the depth of descent can be displayed at all times through the cooperation of the scale plate and the pointer when the lifting component drives the drilling component to descend, thereby facilitating the control of the piling depth.

[0012] Furthermore, the scraping assembly includes an electric push rod embedded in the upper surface of the motherboard and a V-shaped scraping plate fixed to the output end of the electric push rod. A limiting rod is fixedly connected to the upper surface of the V-shaped scraping plate, and the upper end of the limiting rod slides through the bottom surface of the motherboard and extends to the upper part of the motherboard. By setting the scraping assembly, it is convenient to scrape away the debris in the piling area when moving to the piling area, so as to avoid the debris affecting the subsequent drilling work.

[0013] Furthermore, the dust suppression component includes a water tank fixed to the upper surface of the motherboard and a water pump installed on the bottom surface of the motherboard and connected to the water tank. The dust suppression component also includes a water ring fixed to the bottom surface of the motherboard and located around the through hole, and a nozzle installed on the outer surface of the water ring. The output end of the water pump is fixedly connected to a water pipe connected to the water ring. Through the dust suppression component, water can be sprayed on the piling area before and during drilling, thereby preventing dust generated during drilling from being poured out and scattered, thus greatly improving the practicality of the overall device.

[0014] Furthermore, the positioning mechanism includes a fixed frame fixed to the outer surface of the main board and a measuring tape installed on the inner wall of the fixed frame. The outer end of the measuring tape is fixedly connected to a sliding plate, and a rod is slidably connected to a pre-drilled hole on the upper surface of the sliding plate. By setting the positioning mechanism, it is convenient to insert the rod into the ground when moving to the first piling position to record the current piling position. Thus, when moving to the second piling area, the second piling point can be driven according to the distance extended by the measuring tape, without the need to mark the piling point in advance.

[0015] Compared with existing technologies, this pile driver for highway engineering has the following advantages:

[0016] 1. By setting up a lifting component, this utility model can easily drive the drilling component to adjust the depth when driving piles on the ground, and observe the descent distance through the display component. The scraping component can scrape the debris in the pile driving area to the outside when the whole device moves to the pile driving area, so as to avoid the debris affecting the subsequent pile driving. At the same time, before and during pile driving, the dust suppression component can spray water to suppress dust in the pile driving area.

[0017] 2. By setting a fixed-point mechanism, this utility model can easily insert the rod into the ground when moving to the first piling position and record the current piling position. Thus, when moving to the second piling area, the second piling point can be driven according to the distance extended by the measuring tape, without the need to mark the piling point in advance.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] As described in the background section, existing devices can control the drilling depth when driving piles for roads, but they generate a large amount of dust during drilling, which has a significant impact on the surrounding environment. Furthermore, if there is a lot of debris in the drilling area, it is necessary to clean the debris in advance, which increases the workload of the workers. At the same time, before driving piles, it is necessary to mark the pile driving position and strictly control the distance between multiple drill holes. Drilling and pile driving can only be carried out after the marking and debris cleaning are completed. The pre-pile driving operation is extremely cumbersome and affects the efficiency of pile driving. Therefore, this embodiment provides a pile driver for highway engineering. This device can not only control the drilling depth, but also simultaneously reduce the dust generated by drilling. At the same time, when moving the entire device before pile driving, it can scrape the debris in the pile driving area to the outside. It can also display the distance when moving from the first pile driving point to the second point, without the need for manual marking and positioning beforehand.

[0025] See Figure 1 - Figure 4 This embodiment proposes a pile driver for highway engineering, including a main board 1. A pile driving mechanism 4 is provided on the upper part of the main board 1. The pile driving mechanism 4 includes a gantry frame 401 fixed on the upper surface of the main board 1 and a through hole 402 opened on the upper surface of the main board 1. The pile driving mechanism 4 also includes a lifting component connected to the inner top wall of the gantry frame 401 and a drilling component connected to the lifting component. The pile driving mechanism 4 also includes a display component connected to the gantry frame 401.

[0026] refer to Figures 1 to 4The piling mechanism 4 is designed to perform piling operations through the drilling component when piling is required in highway engineering. The lifting component can adjust the height of the drilling component to allow for piling at different depths as needed. The display component allows for real-time observation of the piling depth.

[0027] The lifting assembly includes a first servo motor 403 mounted on the upper surface of the main board 1, and a lead screw 404 fixedly connected to the output shaft of the first servo motor 403 and rotatingly engaged with the inner top wall of the gantry frame 401. The outer surface of the lead screw 404 is threaded with a lifting plate 405.

[0028] By setting up a lifting assembly, the linkage between the first servo motor 403, the lead screw 404 and the lifting plate 405 within the lifting assembly enables the lifting plate 405 to drive the drilling assembly to move up and down, thereby controlling the drilling depth.

[0029] As a supplement, when adjusting the drilling depth, the first servo motor 403 can be started. The output shaft of the first servo motor 403 can drive the lead screw 404 to rotate, so that the lead screw 404 is threadedly engaged with the lifting plate 405, thereby enabling the lifting plate 405 to drive the drilling assembly to adjust its height.

[0030] The lifting assembly also includes a fixing rod 408 fixed to the inner top wall of the gantry frame 401 and slidingly engaged with a pre-drilled hole on the upper surface of the lifting plate 405, and a fixing plate 409 fixed to the lower end of the fixing rod 408 and fixedly connected to the inner wall of the gantry frame 401.

[0031] By setting up a lifting assembly and the fixing rod 408 inside the lifting assembly, the stability of the lifting plate 405 during lifting can be improved, and the shaking of the lifting plate 405 during lifting can be avoided, which would affect the drilling work of the drilling assembly.

[0032] As a supplement, the fixed plate 409 is provided to facilitate the obstruction of the lifting plate 405 during descent, preventing the lifting plate 405 from sliding out of the fixed rod 408 due to excessive descent.

[0033] The drilling assembly includes a second servo motor 406 mounted on the upper surface of the lifting plate 405 and slidingly engaged with a pre-drilled hole on the upper surface of the gantry frame 401. The output shaft of the second servo motor 406 rotates through the lifting plate 405 and is fixedly connected to a drill bit 407 located directly above the through hole 402.

[0034] By setting up the drilling assembly, it is easy to drill and drive piles into the ground, and by setting up the drill bit 407, soil can be discharged upwards during drilling.

[0035] As a supplement, when drilling into the ground, the second servo motor 406 is started. The output shaft of the second servo motor 406 drives the drill bit 407 to rotate, so that the drill bit 407 can pass through the through hole 402 to perform drilling operations into the ground.

[0036] The display components include a guide groove 4010 formed on the inner side wall of the gantry frame 401, and a pointer 4011 that slides with the guide groove 4010 and is connected to the lifting plate 405. A scale plate 4012 that matches the pointer 4011 is fixedly connected to the outer surface of the gantry frame 401.

[0037] By setting up a display component, the depth of descent can be displayed in real time through the cooperation of the scale plate 4012 and the pointer 4011 when the lifting component drives the drilling component to descend, thereby facilitating the control of the piling depth.

[0038] As a supplement, when the lifting plate 405 drives the drilling assembly to descend, the lifting plate 405 can drive the pointer 4011 to slide under the limiting action of the guide groove 4010, so that the pointer 4011 can cooperate with the scale plate 4012. The position of the pointer 4011 on the scale plate 4012 makes it easy to observe the depth of the drilling assembly's descent.

[0039] Support columns 2 are fixedly connected to the four corners of the bottom surface of the motherboard 1, and casters 3 are installed at the lower end of the support columns 2. A cleaning mechanism 5 is also provided on the upper part of the motherboard 1, as well as a positioning mechanism 6 provided on the outer surface of the motherboard 1. The cleaning mechanism 5 includes a scraping component and a dust reduction component located on the bottom surface of the motherboard 1.

[0040] refer to Figures 1 to 4 The cleaning mechanism 5 is equipped with a scraping component, which can easily scrape the debris on the ground to the outside when it is moved to the piling area, so as to avoid the debris affecting the piling construction. In addition, the dust suppression component can easily suppress the dust generated by piling, reducing the need for subsequent cleaning.

[0041] The positioning mechanism 6, when driving a pile at the first designated position, allows the components inside the positioning mechanism 6 to be inserted into the ground, which can automatically set the distance between the pile holes. This enables the distance between the first and second pile positions to be visually displayed during the pile driving process, eliminating the need for manual stringing of lines at the designated positions beforehand.

[0042] The scraping assembly includes an electric push rod 501 embedded in the upper surface of the main board 1, and a V-shaped scraping plate 502 fixed to the output end of the electric push rod 501. A limit rod 503 is fixedly connected to the upper surface of the V-shaped scraping plate 502, and the upper end of the limit rod 503 slides through the bottom surface of the main board 1 and extends to the upper part of the main board 1.

[0043] By setting up a scraping component, it is easy to scrape away debris in the piling area when moving to the piling area, so as to avoid the debris affecting the subsequent drilling work.

[0044] As a supplement, before the entire device moves to the piling area, the electric push rod 501 can be activated. The output end of the electric push rod 501 pushes the V-shaped scraper 502 down, so that the V-shaped scraper 502 contacts the ground. This allows the debris in the piling area to be scraped to the outside when the entire device moves. The setting of the limit rod 503 can improve the stability of the V-shaped scraper 502 when it is raised and lowered.

[0045] The dust suppression assembly includes a water tank 504 fixed on the upper surface of the motherboard 1, and a water pump 505 installed on the bottom surface of the motherboard 1 and connected to the water tank 504. The dust suppression assembly also includes a water ring 507 fixed on the bottom surface of the motherboard 1 and located around the through hole 402, and a nozzle 508 installed on the outer surface of the water ring 507. The output end of the water pump 505 is fixedly connected to a water pipe 506 connected to the water ring 507.

[0046] The dust suppression system allows for water spraying of the piling area before and during drilling, preventing dust generated during drilling from being poured out and scattered, thus greatly improving the overall practicality of the device.

[0047] As a supplement, water spraying before drilling can moisten the ground and soften the soil, improving the efficiency of subsequent drilling. When water spraying is needed, the water pump 505 is started, the input end of the water pump 505 draws water from the water tank 504 and transmits it to the water ring 507 through the water pipe 506, and the nozzle 508 sprays water onto the ground.

[0048] The positioning mechanism 6 includes a fixed frame 601 fixed to the outer surface of the main board 1, and a measuring tape 602 installed on the inner wall of the fixed frame 601. The outer end of the measuring tape 602 is fixedly connected to a slide plate 603, and a pre-drilled hole on the upper surface of the slide plate 603 is slidably connected to an insert rod 604.

[0049] By setting the fixing mechanism 6, it is easy to insert the rod 604 into the ground when moving to the first piling position and record the current piling position. Thus, when moving to the second piling area, the second piling point can be driven according to the distance extended by the measuring tape 602, without the need to mark the piling point in advance.

[0050] As a supplement, the sliding plate 603 can slide at the insertion rod 604, so that when the insertion rod 604 is inserted into the ground, the sliding plate 603 can keep the measuring tape 602 parallel to the ground, thus enabling the marking and positioning of subsequent piling points.

[0051] Working principle: When piling is required during highway construction, the entire device can be moved to the designated position by the support column 2 and the caster wheel 3. Before moving, the electric push rod 501 needs to be activated. The output end of the electric push rod 501 pushes the V-shaped scraper 502 down, so that the V-shaped scraper 502 can scrape the debris in the piling area to the outside, so as to avoid the debris affecting the subsequent piling.

[0052] Before driving the piles, the insertion rod 604 needs to be inserted into the ground to record the current pile position. After the entire device is moved, the water pump 505 is started to pump water into the water tank 504 and transmit the water through the water pipe 506 to the water ring 507, where it is sprayed out by the nozzle 508. This humidifies the pile driving point and reduces dust from the ground during pile driving.

[0053] At this point, the first servo motor 403 can be activated, and its output shaft drives the lead screw 404 to rotate. This causes the lead screw 404 to lower the lifting plate 405. During the descent, the lifting plate 405 is limited by the nozzle 508, thus stably driving the second servo motor 406 and the drill bit 407 to descend. When the second servo motor 406 and the drill bit 407 descend, the second servo motor 406 is activated, and its output shaft drives the drill bit 407 to rotate. This allows the drill bit 407 to pass through the through hole 402 and drill and drive piles into the ground. Simultaneously, water can be sprayed around the area using the dust suppression component. After the first predetermined pile is driven, the distance and scale of the measuring tape 602 can be observed when driving the second pile. This allows for control of the distance between multiple pile driving positions as needed.
