Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, specifically to an automated dynamic deceleration device for concrete pouring. Background Technology

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it hardens. In civil engineering, concrete and other materials are poured into molds to form a predetermined shape. Concrete materials are generally classified into two types based on their source: self-mixed concrete and ready-mixed concrete. Self-mixed concrete is mixed on-site during pouring, while ready-mixed concrete is typically transported to the construction site from a ready-mixed concrete company using pump trucks. Self-mixed concrete is usually stored in containers and manually filled into the molds by construction workers, while ready-mixed concrete is generally transported and filled into the molds using pump trucks and steel pipes.

[0003] When pouring concrete columns, it is common to encounter situations where there is a large vertical height difference between the bottom and top surfaces of the concrete. In such cases, the free fall height of the concrete is too large. Due to the large kinetic energy of the coarse aggregate after overcoming the adhesion under the action of gravity, the falling speed is faster than that of the mortar, which will cause concrete segregation. Therefore, speed baffles are usually installed in the pipeline to reduce the flow rate of the concrete.

[0004] However, in traditional deceleration devices, the contact area between the deceleration plate and the concrete inside the pipeline is fixed and cannot be adjusted. If the concrete flow rate is low, and the contact area between the deceleration plate and the concrete is too large, the deceleration plate will reduce the concrete flow rate too much, thus affecting the concrete pouring speed. If the concrete flow rate is high, and the contact area between the deceleration plate and the concrete is too small, the deceleration plate will not reduce the concrete flow rate and will not improve the segregation phenomenon. Therefore, we propose an automated dynamic deceleration device for concrete pouring. Summary of the Invention

[0005] The purpose of this invention is to provide an automated dynamic deceleration device for concrete pouring, so as to solve the problem in the prior art that the contact area between the deceleration plate inside the pipeline and the concrete is fixed and cannot be adjusted, thus failing to improve the phenomenon of concrete segregation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated dynamic deceleration device for concrete pouring, comprising a conveying pipeline, an installation pipeline fixedly installed at one end of the conveying pipeline, and a dynamic deceleration mechanism for changing the concrete flow rate disposed outside the conveying pipeline, the dynamic deceleration mechanism comprising:

[0007] Several deceleration mechanisms are arranged inside the conveying pipe along the length of the conveying pipe to change the flow velocity of concrete in the conveying pipe.

[0008] A transmission mechanism is provided on one side of the conveying pipe and is used to control the deceleration mechanism;

[0009] A flow detection sensor is installed inside the installation pipe to realize real-time detection of the concrete flow velocity in the delivery pipe.

[0010] Preferably, the deceleration mechanism includes an outer gear disc, a plurality of deceleration plates and an adjustment assembly, wherein the deceleration plates are staggered from top to bottom, and an abutment block is fixedly installed on the inner wall surface of the outer gear disc, and the abutment block has an arc-shaped structure.

[0011] Preferably, the adjusting assembly includes a telescopic plate, with fixed plates fixedly installed on the upper and lower sides of the telescopic plate, a spring fixedly installed at one end of the fixed plate, the end of the telescopic plate near the abutment block having an arc-shaped structure, and a rotating head fixedly installed at the end of the telescopic plate away from the abutment block. A hinge seat is rotatably installed at one end of the rotating head, and a slider is fixedly installed at the top of the hinge seat. A groove for the slider to slide is opened on the bottom surface of the deceleration plate.

[0012] Preferably, the inner wall surface of the conveying pipe is provided with a plurality of telescopic grooves along the circumferential direction for the telescopic plate to move, and the outer wall surface of the conveying pipe is provided with a plurality of mounting grooves along the circumferential direction for installing the spring.

[0013] Preferably, the inner wall surface of the conveying pipe is provided with a plurality of hinge grooves, and a rotating shaft is rotatably installed inside the hinge grooves, the rotating shaft being fixedly installed at one end of the speed reduction plate.

[0014] Preferably, the transmission mechanism includes a rotating rod, and a plurality of drive gears are fixedly installed on the outside of the rotating rod along the length direction of the rotating rod. The drive gears are meshed with an external gear disk. A plug is fixedly installed at the top of the rotating rod, and a plug hole is opened at the bottom of the rotating rod.

[0015] Preferably, the dynamic deceleration mechanism further includes a motor, the power output end of which is fixedly connected to a drive rod, and the bottom end of the drive rod has a socket adapted to the insertion rod.

[0016] Preferably, an outer protective cover is fixedly installed on the outer wall of the conveying pipe at both sides of the outer gear disc, and a rotation groove for the outer gear disc to rotate is opened on the surface of the outer protective cover, and a limit ring is fixedly installed on both sides of the outer gear disc.

[0017] Preferably, a connecting pipe is fixedly installed at the top of the conveying pipe, and a plurality of bolt holes are opened on the outer wall surface of the connecting pipe along the circumferential direction. A snap-fit ​​outer ring adapted to the connecting pipe is fixedly installed at the bottom of the conveying pipe, and a plurality of fastening bolts are threaded on the outer wall surface of the snap-fit ​​outer ring along the circumferential direction.

[0018] Preferably, the flow detection sensor includes a control module, which is electrically connected to both the flow detection sensor and the motor.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention utilizes a combination of a reduction gear and a transmission mechanism. A flow sensor detects the real-time flow velocity of concrete passing through the installed pipe, and this velocity is then uploaded to a control module. The control module controls the motor based on the concrete flow velocity. The motor's operation drives a rotating rod via a drive rod, which in turn drives multiple drive gears. Because the drive gears mesh with the external gear disc, they rotate the external gear disc, causing the abutment block on the inner wall of the external gear disc to contact the end of the telescopic plate. This abutment block compresses the telescopic plate, causing the end of the telescopic plate to... The expansion joint moves into the conveying pipe, and the sliding block moves within the chute via the hinged seat. The longer the expansion joint is within the conveying pipe, the more horizontal the deceleration plate becomes, increasing the contact area between the concrete and the deceleration plate. This also makes it difficult for the concrete to slide down quickly after falling onto the deceleration plate, thus minimizing the flow velocity of the concrete. Conversely, the shorter the expansion joint is within the conveying pipe, the more vertical the deceleration plate becomes, reducing the contact area between the concrete and the deceleration plate. This minimizes the impact on the flow velocity of the concrete, thus achieving dynamic deceleration of the concrete. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figure 1-8 This invention provides a technical solution: an automated dynamic deceleration device for concrete pouring, comprising a conveying pipe 10, with an installation pipe 60 fixedly installed at one end of the conveying pipe 10. The installation pipe 60 has the same diameter as the conveying pipe 10, allowing concrete to enter the conveying pipe 10 from the installation pipe 60. A dynamic deceleration mechanism for changing the concrete flow rate is provided outside the conveying pipe 10. The dynamic deceleration mechanism includes five deceleration mechanisms 20, a transmission mechanism 30, a flow detection sensor 70, and a motor 80. The number of deceleration mechanisms 20 is not limited to five; it can be four, six, or ten, adjusted according to the length of the conveying pipe 10. The deceleration mechanisms 20 are arranged inside the conveying pipe 10 along its length to change the concrete flow rate within the conveying pipe 10.

[0033] In a preferred embodiment, the transmission mechanism 30 is disposed on one side of the conveying pipe 10 and is used to control the deceleration mechanism 20.

[0034] In a preferred embodiment, the flow detection sensor 70 is disposed inside the installation pipe 60. The flow detection sensor 70 is model FSH1-DT1-800 and is used to realize real-time detection of the concrete flow velocity in the conveying pipe 10.

[0035] In a preferred embodiment, the deceleration mechanism 20 includes an outer gear disk 21 and five deceleration plates 23, which are staggered from top to bottom. The outer gear disk 21 is rotatably mounted inside the rotating groove 221, and the deceleration plates 23 are slidably mounted inside the telescopic groove 11. An abutment block 24 is fixedly mounted on the inner wall surface of the outer gear disk 21. The abutment block 24 has an arc-shaped structure. The adjustment component 25 includes a telescopic plate 251. Fixed plates 252 are fixedly mounted on the upper and lower sides of the telescopic plate 251. A spring 253 is fixedly mounted on one end of the fixed plate 252. The end of the telescopic plate 251 near the abutment block 24 has an arc-shaped structure. A rotating head 254 is fixedly mounted on the end of the telescopic plate 251 away from the abutment block 24. A hinge seat 255 is rotatably mounted on one end of the rotating head 254. A slider 256 is fixedly mounted on the top of the hinge seat 255. A groove 231 for the slider 256 to slide is opened on the bottom surface of the deceleration plate 23.

[0036] Furthermore, the flow rate sensor 70 detects the concrete flow rate through the installation pipe 60 in real time, and then uploads the concrete flow rate to the control module. The control module then controls the motor 80 to work based on the concrete flow rate. The motor 80 drives the rotating rod 31 to rotate via the drive rod 81, which in turn drives multiple drive gears 32 to rotate simultaneously. Since the drive gears 32 are meshed with the outer gear disk 21, they can drive the outer gear disk 21 to rotate, causing the abutment block 24 on the inner wall of the outer gear disk 21 to contact the end of the telescopic plate 251. The abutment block 24 then pushes the telescopic plate... The compression of 251 causes the end of the telescopic plate 251 to move into the conveying pipe 10. At the same time, the hinge seat 255 drives the slider 256 to move in the groove 231. The longer the telescopic plate 251 is in the conveying pipe 10, the more horizontal the deceleration plate 23 is, which increases the contact area between the concrete and the deceleration plate 23 and reduces the flow rate of the concrete. Therefore, the shorter the length of the telescopic plate 251 is in the conveying pipe 10, the more vertical the deceleration plate 23 is, which reduces the contact area between the concrete and the deceleration plate 23 and does not significantly affect the flow rate of the concrete.

[0037] To elaborate further, since the abutment block 24 has an arc-shaped structure, when the edge of the abutment block 24 contacts the end of the telescopic plate 251, the telescopic plate 251 moves a small distance. When the highest point of the abutment block 24 contacts the end of the telescopic plate 251, the telescopic plate 251 moves the largest distance. Therefore, by controlling the rotation of the outer gear plate 21, the tilt angle of the deceleration plate 23 in the conveying pipe 10 will be changed, thereby enabling automated deceleration of the concrete according to the flow rate of the concrete.

[0038] In a preferred embodiment, the inner wall surface of the conveying pipe 10 is provided with a plurality of telescopic grooves 11 for the telescopic plate 251 to move along the circumferential direction, and the outer wall surface of the conveying pipe 10 is provided with a plurality of mounting grooves 12 for the spring 253 to be installed along the circumferential direction.

[0039] In a preferred embodiment, the inner wall surface of the conveying pipe 10 is provided with a plurality of hinge grooves 13, and a rotating shaft 14 is rotatably installed inside the hinge groove 13. The rotating shaft 14 is fixedly installed at one end of the speed reduction plate 23. The speed reduction plate 23 can rotate inside the conveying pipe 10 through the rotating shaft 14, thus achieving angle adjustment.

[0040] In a preferred embodiment, the transmission mechanism 30 includes a rotating rod 31, which is rotatably mounted on the outer wall of the conveying pipe 10 via a mounting plate. Five drive gears 32 are fixedly mounted on the outside of the rotating rod 31 along its length. The drive gears 32 are meshed with the external gear disc 21. A plug rod 33 is fixedly mounted on the top of the rotating rod 31, and a plug hole 34 is provided at the bottom of the rotating rod 31. The plug hole 34 is adapted to the plug rod 33.

[0041] In a preferred embodiment, the power output end of the motor 80 is fixedly connected to a drive rod 81. The bottom end of the drive rod 81 is provided with a socket that is compatible with the insertion rod 33. The insertion rod 33 at the top of the rotating rod 31 is inserted into the socket, thereby realizing the docking between the drive rod 81 and the rotating rod 31.

[0042] In a preferred embodiment, an outer protective cover 22 is fixedly installed on the outer wall of the conveying pipe 10 on both sides of the outer gear disk 21. The outer protective cover 22 can protect the outer gear disk 21. A rotating groove 221 for the outer gear disk 21 to rotate is opened on the surface of the outer protective cover 22. The outer gear disk 21 is rotatably installed inside the rotating groove 221. Limiting rings 26 are fixedly installed on both sides of the outer gear disk 21. When the outer gear disk 21 rotates, the limiting rings 26 will also rotate in the rotating groove 221, thus fixing the outer gear disk 21 and preventing the outer gear disk 21 from shifting.

[0043] In a preferred embodiment, the flow detection sensor 70 includes a control module, which specifically uses an FPGA chip. The control module is electrically connected to both the flow detection sensor 70 and the motor 80.
