Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a concrete pouring device for root knot pile construction. Background Art

[0002] "Genjiepanju" means a solid foundation with a strong force. Genjiepanju piles are also called pipe-sinking cast-in-place piles. During the construction of a genjiepanju pile, a casing and pile tip that matches the designed pile diameter are usually used. The casing end is inserted into the pile tip and then sunk into the stratum. When the casing reaches the designed elevation, a steel cage is placed inside the casing, and concrete is poured into the pile body. Finally, the casing is pulled out to complete the pile. When pouring concrete into the genjiepanju pile body, a pouring bucket is often used to lift the concrete. That is, after the concrete transport truck is in place, the crane's main hook controls the pouring bucket, and the auxiliary hook controls the valve cover at the connection between the pouring bucket and the pipe. The main and auxiliary hooks work together to complete the concrete lifting.

[0003] The existing technology has the following technical problems:

[0004] The Chinese patent publication, patent number CN219508578U, discloses a boom-type valve pouring bucket for pouring concrete into a pipe-sinking cast-in-place pile. The device uses a material baffle plate equipped with a boom-type valve to seal the discharge port of the pouring bucket body. In the actual operation process, the first step is to ensure that the discharge port of the pouring bucket is blocked by the material baffle plate before the pouring bucket is filled with concrete. After the pouring bucket is filled with the first bucket of concrete, the discharge port is opened to utilize the concrete's own gravitational potential energy to impact and remove the sediment at the bottom of the pile hole. However, the current boom-type valve will enter the inside of the guide barrel after the material baffle plate is opened. This design accidentally forms an obstacle to the impact force of the concrete flowing downward, resulting in a weakened impact effect of the concrete on the sediment at the bottom of the pile hole, thereby affecting the sediment removal effect.

[0005] Existing grouting buckets usually consist of a grouting bucket and a material guide cylinder connected to its discharge port. When the grouting bucket is lowered to the pile hole area by a crane, it is often difficult for operators to quickly determine whether the grouting bucket has pressed onto the steel cage. If timely detection and measures are not taken, once the grouting bucket directly presses onto the steel cage, not only may the structure of the steel cage be damaged, but the weight of the grouting bucket itself may also cause the steel cage to sink or shift. These adverse consequences will directly lead to uneven distribution of concrete inside the pile hole and may even cause voids that affect the structural strength, thereby posing a potential threat to project quality and safety. Utility Model Content

[0006] The purpose of the utility model is to provide a concrete pouring device for root knot pile construction, which is used to solve the problems that when the existing device is used, the material baffle enters the material guide barrel after the boom valve is opened, hindering the impact force of the concrete and weakening the sediment removal effect; when the pouring bucket descends, it is difficult to judge whether it is in contact with the steel cage. If it is directly pressed, the steel cage structure will be damaged or it will sink and deviate, resulting in uneven distribution of concrete in the pile hole, possible voids, and threatening the quality and safety of the project.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a concrete pouring device for root knot pile construction, comprising a pouring bucket, a material guide cylinder connected to the pouring bucket discharge port, a support and protection mechanism arranged on the material guide cylinder, a detection and alarm mechanism arranged on the support and protection mechanism, a lifting and anti-pressure support mechanism arranged on the support and protection mechanism, a lifting valve mechanism arranged on the support and protection mechanism and used to block the pouring bucket discharge port, and a controller arranged on the lifting valve mechanism, wherein the detection and warning mechanism, the lifting and anti-pressure support mechanism, and the lifting valve mechanism are all connected to the concrete pouring device. The controller is electrically connected; the lifting valve mechanism includes an inverted U-shaped frame provided on the supporting and protecting mechanism and located on one side of the filling bucket, a hydraulic cylinder provided on the upper side of the inverted U-shaped frame, a lifting horizontal plate connected to the output end of the hydraulic cylinder and located above the filling bucket, a lifting column connected to the lower side of the lifting horizontal plate, a closed sphere connected to one end of the lifting column and acting on the discharge port of the filling bucket, a plurality of support rods provided on the inner wall of the filling bucket and arranged at intervals, and a sleeve connected to one end of the plurality of support rods, the sleeve being sleeved on the outer wall of the lifting column and slidingly matched with the lifting column, and the controller being provided on one side of the inverted U-shaped frame.

[0008] Furthermore, the supporting and protecting mechanism includes a circular shell provided on the outer wall of the material guide barrel, a circular opening provided on the lower side of the circular shell, a plurality of telescopic rods provided on the lower side of the circular shell and arranged in a circular interval, and a first supporting foot provided at one end of the telescopic rod. The circular opening is located between the plurality of telescopic rods, the lower side of the inverted U-shaped frame is connected to the upper side of the circular shell, and one end of the material guide barrel passes through the circular opening and extends to the bottom of the circular shell.

[0009] Furthermore, an observation window is provided on the upper side of the circular shell.

[0010] Furthermore, the detection and warning mechanism includes a first connecting plate and a second connecting plate arranged on the inner wall of the circular shell and arranged opposite to each other, two infrared emitters arranged on the first connecting plate and arranged at intervals, an infrared receiver arranged on the second connecting plate and arranged corresponding to the two infrared emitters respectively, and a buzzer alarm arranged on the upper side of the circular shell and located between the inverted U-shaped frame and the filling bucket. The buzzer alarm, two infrared emitters, two infrared receivers, and the hydraulic cylinder are all electrically connected to the controller, and the material guide barrel is correspondingly arranged between the two infrared emitters.

[0011] Furthermore, the lifting and anti-pressure support mechanism includes two electric push rods arranged on the upper side of the inner wall of the circular shell and arranged at intervals, and a second supporting foot connected to one end of the electric push rod. The two electric push rods are respectively located on one side of the material guide barrel, and the second supporting foot is correspondingly arranged above the circular opening. The two electric push rods are electrically connected to the controller.

[0013] Furthermore, a plurality of hanging rings arranged in an annular manner and spaced apart are provided on the top of the outer wall of the pouring hopper.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] When pouring the concrete for the root pile, first inject the first bucket of concrete into the pouring bucket. Then, the discharge port of the pouring bucket is opened by controlling the lifting valve mechanism. The lifting valve mechanism is composed of an inverted U-shaped frame, a hydraulic cylinder, a lifting horizontal plate, a lifting column, a closed sphere, a sleeve and multiple support rods. When the discharge port is in the open state, the closed sphere is lifted to the internal top of the pouring bucket. Then, while controlling the opening and closing of the discharge port of the pouring bucket, the device maintains the downward fluidity and impact force of the concrete, making it easy to remove the sediment at the bottom of the pile hole through the impact force of the concrete itself.

[0016] .Through the close cooperation of the support and protection mechanism, the detection and warning mechanism, and the lifting and anti-pressure support mechanism installed on the material guide barrel, when the steel cage reaches the position of the detection and warning mechanism, the warning mechanism will be immediately triggered, and a supporting action will be taken to prevent the grouting bucket from further descending; furthermore, when the grouting bucket of the device descends to the pile hole area, it can automatically detect and determine whether it is pressing on the steel cage. Once a potential risk is detected, it is convenient to immediately issue an alarm and automatically take measures to prevent the grouting bucket from continuing to descend, thereby ensuring the quality of the project and construction safety, and avoiding potential hidden dangers.

[0022] See also Figure 1-4A concrete pouring device for root-knot pile construction includes a pouring bucket 1, a guide cylinder 2 connected to the discharge port of the pouring bucket 1, a support and protection mechanism 3 provided on the guide cylinder 2, a detection and alarm mechanism provided on the support and protection mechanism 3, a lifting and anti-pressure support mechanism provided on the support and protection mechanism 3, a lifting valve mechanism 4 provided on the support and protection mechanism 3 and used to block the discharge port of the pouring bucket 1, and a controller 23 provided on the lifting valve mechanism 4. The detection and warning mechanism, the lifting and anti-pressure support mechanism, and the lifting valve mechanism 4 are all electrically connected to the controller 23; the lifting valve mechanism 4 includes an inverted U-shaped frame 5 provided on the support and protection mechanism 3 and located on one side of the pouring bucket 1, and a valve 23 installed on the upper side of the inverted U-shaped frame 5. The hydraulic cylinder 6, the lifting horizontal plate 7 connected to the output end of the hydraulic cylinder 6 and located above the pouring bucket 1, the lifting column 8 connected to the lower side of the lifting horizontal plate 7, the closed sphere 9 connected to one end of the lifting column 8 and acting on the discharge port of the pouring bucket 1, a plurality of support rods 10 connected to the inner wall of the pouring bucket 1 and arranged at intervals, and a sleeve 11 connected to one end of the plurality of support rods 10. The sleeve 11 is sleeved on the outer wall of the lifting column 8 and slides with the lifting column 8. The controller 23 is installed on one side of the inverted U-shaped frame 5; when the concrete pouring operation of the pile body is carried out, the crane controls the guide barrel 2 connected to the pouring bucket 1 to be inserted into the pile hole. As the pouring bucket 1 gradually approaches the steel cage, the supporting and protecting mechanism 3 supports the pouring bucket 1. Once the top of the steel cage is located at the detection and warning mechanism, the detection and warning mechanism transmits the detected information to the controller 23, and the detection and warning mechanism starts the alarm mode and controls the lifting and anti-pressure support mechanism to start, so that it descends until it contacts the ground, thereby preventing the pouring bucket 1 from further descending and avoiding it from pressing down on the steel cage; before adding the first bucket of concrete into the pouring bucket 1, the controller 23 instructs the hydraulic cylinder 6 to start, and under the drive of the hydraulic cylinder 6, the lifting cross plate 7 and the lifting column 8 connected thereto work together to drive the closing sphere 9 to descend until it is blocked at the discharge port of the pouring bucket 1. After the blocking is completed, the pouring bucket 1 is filled with concrete, and then the hydraulic cylinder 6 is started again to drive the closing sphere 9 It rises to open the discharge port of the pouring bucket 1, and the sealing sphere 9 is lifted to the internal top of the pouring bucket 1. Then, the concrete in the pouring bucket 1 uses its own impact force to impact and remove the sediment at the bottom of the pile hole. Furthermore, while controlling the opening and closing of the discharge port of the pouring bucket 1, the device maintains the downward fluidity and impact force of the concrete, making it easy to remove the sediment at the bottom of the pile hole through the impact force of the concrete itself. In addition, when the pouring bucket 1 descends to the pile hole area, it can automatically detect and determine whether it is pressing on the steel cage. Once a potential risk is detected, it is easy to immediately sound an alarm and automatically take measures to prevent the pouring bucket 1 from continuing to descend, thereby ensuring the quality of the project and construction safety and avoiding potential hidden dangers.

[0023] The supporting and protecting mechanism 3 includes a circular shell 12 connected to the outer wall of the material guide barrel 2, a circular opening 13 provided on the lower side of the circular shell 12, a plurality of telescopic rods 14 connected to the lower side of the circular shell 12 and arranged in a ring-shaped interval, and a first supporting foot 15 connected to one end of the telescopic rod 14. The circular opening 13 is located between the plurality of telescopic rods 14, the lower side of the inverted U-shaped frame 5 is connected to the upper side of the circular shell 12, and one end of the material guide barrel 2 passes through the circular opening 13 and extends to the bottom of the circular shell 12; the telescopic rod 14 adopts the existing standard structure, which consists of an outer shell, an inner rod and a spring connected therebetween, wherein the inner rod can slide inside the outer shell; as the pouring bucket 1 descends, the plurality of first supporting feet 15 contact the ground and play a supporting role. Through the setting of the telescopic rod 14, it can adapt to the unevenness of the ground. At the same time, the steel cage passes through the circular opening 13 and enters the interior of the circular shell 12, providing support for the pouring bucket 1.

[0024] An observation window 26 is provided on the upper side of the circular shell 12; through the observation window 26, the pouring of concrete in the pile hole can be easily observed.

[0025] The detection and warning mechanism includes a first connecting plate 16 and a second connecting plate 18 connected to the inner wall of the circular shell 12 and arranged opposite to each other, two infrared transmitters 17 installed on the first connecting plate 16 and arranged at intervals, an infrared receiver 19 installed on the second connecting plate 18 and arranged corresponding to the two infrared transmitters 17, and a buzzer alarm 22 installed on the upper side of the circular shell 12 and located between the inverted U-shaped frame 5 and the pouring hopper 1. The buzzer alarm 22, the two infrared transmitters 17, the two infrared receivers 19, and the hydraulic cylinder 6 are all electrically connected to the controller 23. The guide barrel 2 is provided with two corresponding between the infrared transmitters 17; when the steel cage reaches the detection area formed by the two infrared transmitters 17 and the corresponding two infrared receivers 19, the steel cage blocks the infrared signal emitted by the infrared transmitter 17. Once the infrared receiver 19 is unable to receive the infrared light emitted by the infrared transmitter 17, this change is immediately captured by the system and converted into corresponding information, which is then transmitted to the controller 23. The controller 23 instructs the buzzer alarm 22 to start and sound an alarm. This alarm is intended to promptly remind the operator to suspend the crane's lowering operation of the pouring bucket 1.

[0026] The lifting and anti-pressure support mechanism includes two electric push rods 20 installed on the upper side of the inner wall of the circular shell 12 and arranged at intervals, and a second supporting foot 21 connected to one end of the electric push rod 20. The two electric push rods 20 are respectively located on one side of the material guide barrel 2, and the second supporting foot 21 is correspondingly arranged above the circular opening 13. The two electric push rods 20 are both electrically connected to the controller 23; when the steel cage reaches the detection area, the controller 23 simultaneously instructs the two electric push rods 20 to start, driving the two second supporting feet 21 to descend to the ground to form a support structure. This action prevents the pouring bucket 1 from further descending.

[0027] The upper side of the circular shell 12 is connected to a power supply housing 24 located in the inverted U-shaped frame 5. A battery 25 is provided in the power supply housing 24. The battery 25 is electrically connected to the controller 23, the buzzer alarm 22, the hydraulic cylinder 6, the two electric push rods 20, the two infrared transmitters 17, and the two infrared receivers 19. The battery 25 can provide power to the controller 23, the buzzer alarm 22, the hydraulic cylinder 6, the two electric push rods 20, the two infrared transmitters 17, and the two infrared receivers 19.

[0028] The top of the outer wall of the pouring bucket 1 is provided with a plurality of lifting rings 27 arranged at intervals in a ring shape; through the plurality of lifting rings 27, it is convenient to connect the pouring bucket 1 with a lifting rope, and to lift and lower the pouring bucket 1 and the guide barrel 2 by a crane.

[0029] Working principle: When pouring concrete for the root pile, the crane controls the guide tube 2 connected to the pouring bucket 1 to be inserted into the pile hole. As the pouring bucket 1 gradually approaches the steel cage, multiple first support legs 15 contact the ground to play a supporting role. Once the steel cage reaches the detection area formed by the two infrared transmitters 17 and the corresponding two infrared receivers 19, the steel cage blocks the infrared signal emitted by the infrared transmitter 17. Once the infrared receiver 19 cannot receive the infrared signal emitted by the infrared transmitter 17, this change is immediately captured by the system and converted into corresponding information. The information is then transmitted to the controller 23. The controller 23 instructs the buzzer alarm 22 to start and sound an alarm. This alarm is intended to promptly remind the operator to suspend the crane's lowering operation of the pouring bucket 1. The controller 23 simultaneously instructs the two electric push rods 20 to start, driving the two second support legs 21 to descend to the ground to form a supporting structure. This action prevents the pouring bucket 1 from further descending, avoiding it from pressing down on the steel cage. When adding concrete to the pouring bucket 1, the controller 23 instructs the two electric push rods 20 to start and drive the two second support legs 21 to descend to the ground to form a supporting structure. This action prevents the pouring bucket 1 from further descending and prevents it from pressing down on the steel cage. Before the first bucket of concrete is poured, the controller 23 instructs the hydraulic cylinder 6 to start. Under the drive of the hydraulic cylinder 6, the lifting cross plate 7 and the lifting column 8 connected thereto work together to drive the sealing sphere 9 down until it is blocked at the discharge port of the pouring bucket 1. After the blocking is completed, the pouring bucket 1 is filled with concrete. Subsequently, the hydraulic cylinder 6 is started again, driving the sealing sphere 9 up, so that the discharge port of the pouring bucket 1 is opened, and the sealing sphere 9 is lifted to the internal top of the pouring bucket 1. As a result, the concrete in the pouring bucket 1 uses its own impact force to impact and remove the sediment at the bottom of the pile hole; furthermore, while controlling the opening and closing of the discharge port of the pouring bucket 1, the device maintains the fluidity and impact force of the concrete downward, facilitating the removal of the sediment at the bottom of the pile hole through the impact force of the concrete itself; in addition, when the pouring bucket 1 descends to the pile hole area, it can automatically detect and determine whether it is pressing on the steel cage. Once a potential risk is detected, an alarm is immediately issued and measures are automatically taken to prevent the pouring bucket 1 from continuing to descend, thereby ensuring the quality of the project and construction safety and avoiding potential hidden dangers.
