Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, and in particular to a concrete diversion device and pouring equipment. Background Technology

[0002] The interior of the steel-concrete composite section is divided into a large number of independent sealed chambers by multiple transverse diaphragms. During the construction phase, concrete needs to be delivered to each sealed chamber simultaneously. At the same time, the steel arch rib has a large-angle inclined pouring surface. In order to ensure the compactness of the pouring and the integrity of the structure, it is necessary to use a diversion device to achieve multi-point and regional controllable material delivery. The diversion device used in traditional concrete construction generally adopts the arrangement of a material collection hopper with multiple discharge ports and guide pipes. It relies on a single-stage diversion structure to complete the multi-point delivery of concrete. It is a commonly used material delivery equipment in the current steel-concrete structure pouring operation.

[0003] Existing single-stage concrete diversion devices have several shortcomings in on-site construction of steel-concrete composite sections: First, to ensure the structural stability of the hopper and guide pipe under suspended conditions, a large number of independent support structures need to be erected externally. This results in a large number of components, a significant overall weight, and cumbersome on-site hoisting, disassembly, and transportation operations, making it unsuitable for the suspended pouring environment of steel arch ribs. Second, the device only relies on the hopper outlet for primary diversion, and pipeline control can only adjust the main pipeline's on / off state, lacking a secondary independent material control structure, thus failing to match the steel-concrete composite structure. The construction requirements for simultaneous and independent pouring of more than ten sealed chambers in the combined section are as follows: Thirdly, the single main pipeline on / off control mode cannot individually open and close each pouring point. For the large-angle inclined pouring surface of the steel arch rib, it is not possible to control the material feeding of each chamber in a layered and regional construction sequence. When pouring the inclined surface, quality defects such as concrete slippage, over-pouring of the lower layer, and insufficient pouring of the upper layer are prone to occur. The controllability of pouring accuracy is poor, which greatly increases the difficulty of on-site construction operations and makes it difficult to meet the engineering requirements for fine pouring of multiple sealed chambers and large-angle inclined surfaces in the steel-concrete combined section. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: existing diversion devices can only supply concrete to a portion of the concrete, and are not suitable for concrete pouring in multiple enclosed chambers; the overall weight of the diversion device is relatively heavy, and the support system needs to be set in a stable location, making it unsuitable for concrete pouring in a suspended state; the diversion device can only control the opening and closing of the main diversion pipe, and cannot be used for concrete pouring on inclined surfaces. Therefore, this invention proposes a concrete diversion device and pouring equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concrete diversion device, comprising:

[0007] The hopper has multiple discharge ports at its bottom;

[0008] A primary diversion component is installed at the bottom of the hopper. The primary diversion component includes multiple primary circular chutes and multiple primary control switches. The multiple primary circular chutes are circumferentially and equidistantly installed at the bottom of the hopper, with one end connected to the discharge port. The multiple primary control switches are respectively installed at the bottom of the multiple primary circular chutes. The multiple primary circular chutes are fixed to the arch rib partition by clamps.

[0009] Multiple sets of secondary diversion components are installed at the bottom ends of multiple primary circular chutes. Each secondary diversion component includes a secondary material distribution trough, multiple secondary circular chutes, and multiple secondary control switches. The secondary material distribution trough is connected to the bottom end of the primary circular chutes, and the tops of the multiple secondary circular chutes are fixedly connected to the secondary material distribution trough. The multiple secondary control switches are installed at the tops of the multiple secondary circular chutes.

[0010] All of the primary control switches and the multiple secondary control switches are plate-shaped gates.

[0011] As a preferred embodiment, the hopper sidewall is symmetrically provided with rotating holes, each of which is equipped with a sealed bearing. A rotating shaft is rotatably mounted on each of the two sealed bearings. The rotating shaft passes horizontally through the hopper. The hopper is provided with a power drive assembly for driving the rotating shaft to rotate. Both ends of the rotating shaft are provided with impact vibration assemblies for driving the hopper to vibrate.

[0012] As a preferred embodiment, the power drive assembly includes a fixed base and multiple arc-shaped blades. The fixed base is fixedly sleeved in the middle of the rotating shaft and is coaxially arranged with the rotating shaft. The multiple arc-shaped blades are circumferentially equidistantly installed on the side of the fixed base.

[0013] As a preferred embodiment, the impact vibration assembly includes a rotating base, two support rods, two metal impact balls, and a metal resonant column. The rotating base is fixedly sleeved on one end of the rotating shaft. One end of each of the two support rods is mounted on the rotating base via an elastic sliding component. The two metal impact balls are fixedly mounted on one end of the support rods. The metal resonant column is fixedly mounted on the side of the hopper. The two metal impact balls intermittently contact the metal resonant column. An elastic connection portion is provided in the middle of each of the two support rods.

[0014] As a preferred embodiment, the rotating base is symmetrically provided with sliding grooves, the elastic sliding component includes a telescopic spring and a sliding base, the sliding base is horizontally slidably installed in the sliding groove, the telescopic spring is horizontally fixedly installed in the sliding groove and one end is fixedly connected to the sliding base, and the support rod is vertically fixedly installed on the sliding base.

[0015] As a preferred embodiment, both support rods are vertically provided with centrifugal sliding holes, and two first positioning blocks and two second positioning blocks are fixedly installed on the rotating seat. Each of the two first positioning blocks is provided with a first positioning groove, and each of the two second positioning blocks is provided with a second positioning groove. The depth of the second positioning groove is greater than that of the first positioning groove, and both support rods are provided with locking components for locking themselves.

[0016] As a preferred embodiment, the locking assembly includes a centrifugal block slidably installed in a centrifugal sliding hole, a return spring fixedly installed in the centrifugal sliding hole, and two L-shaped positioning rods symmetrically fixedly installed on the centrifugal block. One end of the return spring is fixedly connected to the centrifugal block. One end of the two L-shaped positioning rods on one of the support rods is inserted into two first positioning slots, and one end of the two L-shaped positioning rods on the other support rod is inserted into two second positioning slots.

[0017] As a preferred embodiment, the metal resonant column has a cylindrical cavity inside, and a connecting pipe connected to the cylindrical cavity is installed on the upper surface of the metal resonant column. A sound amplification cover is fixedly installed at the upper end of the connecting pipe. Multiple thin steel wires are provided inside the cylindrical cavity. One end of the multiple thin steel wires is fixed to the inner wall of the cylindrical cavity, and the other end is suspended. A metal plate is fixedly installed on the inner wall of the cylindrical cavity, and the suspended end of the multiple thin steel wires is in contact with the surface of the metal plate.

[0018] As a preferred embodiment, warning seats are fixedly installed at both ends of the rotating shaft. The warning seats have cavities inside, and support rods are horizontally fixedly installed in the cavities. Rotating seats are rotatably sleeved on the support rods, and mounting plates are symmetrically fixedly installed on the rotating seats. LED light panels are fixedly installed on both mounting plates. A connecting plate is fixedly installed on the lower surface of the rotating seats, and a counterweight column is fixedly installed on the lower side of the connecting plate. The two mounting plates are symmetrically arranged on both sides of the connecting plate, and multiple square holes are equidistantly opened on the surface of the warning seats.

[0019] A concrete pouring device includes: multiple connecting flanges, multiple pouring pipes, and the aforementioned concrete diversion device. The multiple connecting flanges are respectively fixedly installed at one end of the multiple pouring pipes, and the multiple connecting flanges are respectively connected to the bottom of the multiple secondary circular chutes.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The system adopts a dual diversion structure with a primary circular chute and a secondary distribution trough. Compared with traditional single-stage diversion equipment, it has more diversion points and can simultaneously deliver concrete to multiple sealed chambers in the steel-concrete composite section. It is suitable for the construction needs of layered pouring on the steep slope of the steel arch. The primary and secondary circular chutes are equipped with independent plate gate primary and secondary control switches, respectively. Workers can open and close any pouring point independently. The pouring of each chamber can be completed in sequence according to the construction order, which can alleviate the problems of concrete slippage on the inclined surface, over-pouring of the lower layer, and insufficient pouring of the upper layer, and improve the compactness of the concrete.

[0022] 2. The entire device relies on the arch rib partition to fix the primary circular chute through clamps. The three primary circular chutes form a triangular support system to directly support the hopper, eliminating the need for a large number of independent support structures. This simplifies the on-site setup process, reduces the overall weight of the device, and facilitates hoisting and transportation. It is suitable for steel arch rib suspended casting conditions. The secondary circular chute is relatively light and can be stably installed by connecting only the upper end to the distribution trough, further reducing the amount of on-site fixing work.

[0023] 3. The hopper is equipped with a rotating shaft with multiple sets of arc-shaped blades. When the pump continuously delivers concrete into the hopper, the falling concrete material will continuously impact the arc-shaped blades. The rotating shaft is driven by the impact force of the material itself to maintain a uniform rotation speed. During the rotation, the metal impact ball will periodically and intermittently strike the metal resonant column, causing the entire hopper to generate small-amplitude low-frequency vibrations. This can reduce the accumulation of concrete aggregate and the blockage of pipelines, and ensure that the concrete is smoothly delivered downwards.

[0024] 4. When the pump feeding rate increases and the material flow rate in the hopper increases, the impact force of the material increases, and the rotation speed of the rotating shaft increases accordingly. The centrifugal block inside the rotating seat slides outward under the action of centrifugal force, causing the L-shaped positioning rod to disengage from the first positioning groove. The sliding seat, which was originally limited by the positioning groove, loses its constraint. The elastic force of the telescopic spring will push the sliding seat to move outward of the rotating seat. The metal impact ball on the corresponding side will shift accordingly and no longer continuously impact the metal resonance column. The overall impact frequency and vibration amplitude of the hopper decrease synchronously, avoiding the separation of aggregate and slurry inside the concrete due to continuous strong vibration at high speed. This reduces defects such as honeycomb and segregation in the components after pouring, and ensures the workability and molding quality of the concrete.

[0025] 5. If the operator fails to reduce the pumping speed in time and the material feeding continues to exceed the standard, the sliding seats on both sides will shift one after another. The metal impact balls on the two support rods will be completely misaligned with the metal resonance column. The metal resonance column will no longer be subjected to impact excitation. The fine steel wire in the inner cavity of the metal resonance column will lose its vibration excitation and stop scraping the internal metal plate. The warning sound that was originally amplified by the sound amplifier will disappear. On-site construction personnel can intuitively judge whether the current feeding speed exceeds the reasonable range through the change in sound and reduce the pump's delivery flow in time to avoid concrete segregation caused by excessive feeding and uncontrolled vibration from the source.

[0026] 6. Warning seats are synchronously installed at both ends of the rotating shaft. The internal LED light panel is kept relatively stationary by the counterweight column. The rotating shaft drives the outer shell of the warning seat to rotate continuously. The light will intermittently shine through the square holes on the surface of the warning seat, forming a flashing light that can be identified from a distance. This allows personnel at different work points on the ground and on the arch to observe the operation of the hopper in real time. If the feeding of the overhead pump is not adjusted in time, the height of the concrete pile inside the hopper will continue to rise until it submerges the arc-shaped blades inside the hopper. The material can no longer drive the blades to rotate, the rotating shaft will stop rotating, and the flashing light will disappear. This will visually remind the on-site personnel to stop feeding immediately to prevent the hopper from overflowing and the chutes at all levels from becoming completely blocked, thus reducing the extra time spent cleaning up blockages and dealing with overflows.

[0043] Example 1

[0044] Reference Figures 1-3 A concrete diversion device includes: a hopper 1, a primary diversion component, and multiple sets of secondary diversion components. The bottom of the hopper 1 is provided with multiple discharge ports. The primary diversion component is installed at the bottom of the hopper 1. The primary diversion component includes multiple primary circular chutes 2 and multiple primary control switches 3. The multiple primary circular chutes 2 are circumferentially and equidistantly installed at the bottom of the hopper 1, and one end is connected to the discharge port. The multiple primary control switches 3 are respectively installed at the bottom of the multiple primary circular chutes 2. The multiple primary circular chutes 2 are fixed to the arch rib partition by clamps. The multiple sets of secondary diversion components are respectively installed at the bottom ends of the multiple primary circular chutes 2. The secondary diversion component includes a secondary distribution trough 4, multiple secondary circular chutes 5, and multiple secondary control switches 6. The secondary distribution trough 4 is connected to the bottom end of the primary circular chutes 2. The tops of the multiple secondary circular chutes 5 are all fixedly connected to the secondary distribution trough 4. The multiple secondary control switches 6 are respectively installed at the top of the multiple secondary circular chutes 5. The multiple primary control switches 3 and the multiple secondary control switches 6 are all plate-shaped gates.

[0045] The hopper 1 is welded to the primary circular chute 2. The three primary circular chute 2 are fixed to the arch rib diaphragm by clamps during the overall hoisting. The primary circular chute 2 serves as the support system for the hopper 1. The hopper 1 does not require any stabilization measures. The hopper 1 is made of 8mm thick steel plate welded into a bucket-shaped structure. The primary circular chute 2 is made of ф273*10mm steel pipe. The discharge port on the hopper 1 is connected to the primary circular chute 2. The secondary distribution trough 4 further distributes the concrete, increasing the amount of concrete distributed while accurately positioning the pouring position. The secondary circular chute 5 is made of ф273*10mm steel pipe and is relatively lightweight. It does not need to be fixed when connected to the upper stabilizing structure.

[0046] A primary control switch 3 and a secondary control switch 6 are respectively installed on the primary circular chute 2 and the secondary circular chute 5. The control switches are plate-shaped gates, which can be inserted into the corresponding openings to achieve the concrete sealing state. The primary control switch 3 is located at the bottom of the primary circular chute 2, and the secondary control switch 6 is located at the top of the secondary circular chute 5. The control switches are concentrated in places that can be reached by people to reduce personnel movement. When the pouring surface is inclined, the bottom cavity is poured first. The pouring can be stopped by closing the corresponding secondary control switch 6. The concrete pouring of each flow direction is completed in sequence.

[0047] The dual diversion device can accurately and controllably deliver concrete to the corresponding position, making the pouring process quick and convenient. The device can adapt well to pouring structures with multiple diversion directions. Only one fixed point is set for the entire structure, reducing the cumbersome support system and lightening the overall weight.

[0048] Example 2

[0049] Reference Figure 5 The hopper 1 has symmetrical rotating holes on its side wall. Each rotating hole is equipped with a sealed bearing 7, and a rotating shaft 8 is rotatably mounted on each of the two sealed bearings 7. The rotating shaft 8 passes horizontally through the hopper 1. The hopper 1 is equipped with a power drive assembly for driving the rotating shaft 8 to rotate. Both ends of the rotating shaft 8 are equipped with impact vibration assemblies for driving the hopper 1 to vibrate. The sealed bearings 7 provide lateral support for the rotating shaft 8 and prevent concrete slurry from seeping out of the rotating holes. During construction, the overhead pump continuously delivers concrete into the hopper 1. The falling material impacts the power drive assembly, causing the rotating shaft 8 to rotate at a uniform speed. The impact vibration assemblies at both ends synchronously and intermittently impact the outer wall of the hopper 1, causing the hopper 1 to produce small-amplitude, low-frequency vibrations. The vibration can prevent aggregate accumulation from clogging the outlet of the primary circular chute 2 and ensure that the concrete is continuously and smoothly diverted and transported downwards.

[0050] Reference Figure 5 The power drive assembly includes a fixed base 9 and multiple arc-shaped blades 10. The fixed base 9 is fixedly sleeved in the middle of the rotating shaft 8 and is coaxial with the rotating shaft 8. The multiple arc-shaped blades 10 are circumferentially equidistantly installed on the side of the fixed base 9. The arc-shaped blades 10 rotate synchronously with the rotating shaft 8. No external motor or hydraulic power is required. The entire rotating shaft 8 can be continuously operated by relying solely on the impact kinetic energy of the falling concrete material. This eliminates the need for additional power equipment, simplifies on-site pipeline layout, reduces electrical safety hazards, and is suitable for outdoor bridge construction environments.

[0051] Reference Figure 6 and Figure 7The impact vibration assembly includes a rotating seat 11, two support rods 12, two metal impact balls 13, and a metal resonance column 14. The rotating seat 11 is fixedly sleeved on one end of the rotating shaft 8. One end of each of the two support rods 12 is mounted on the rotating seat 11 through an elastic sliding component. The two metal impact balls 13 are fixedly mounted on one end of each support rod 12. The metal resonance column 14 is fixedly mounted on the side of the hopper 1. The two metal impact balls 13 intermittently contact the metal resonance column 14. The middle part of each of the two support rods 12 is provided with an elastic connection part 15. The rotating shaft 8 drives the rotating seat 11 to rotate continuously, and the support rods 12 follow in a circular motion. The metal impact balls 13 periodically strike the metal resonance column 14, transmitting vibration to the entire hopper 1. The elastic connection part 15 buffers the impact force, reducing the probability of fatigue damage caused by long-term reciprocating deformation of the support rods 12. Continuous vibration can break up agglomerated sand and gravel aggregates, reducing the risk of pipeline blockage.

[0052] Reference Figure 8 The rotating seat 11 is symmetrically provided with sliding grooves 16. The elastic sliding component includes a telescopic spring 17 and a sliding seat 18. The sliding seat 18 is horizontally slidably installed in the sliding groove 16. The telescopic spring 17 is horizontally fixedly installed in the sliding groove 16, and one end is fixedly connected to the sliding seat 18. The support rod 12 is vertically fixedly installed on the sliding seat 18. Under normal feeding flow, the telescopic spring 17 remains in a compressed state, and the metal impact ball 13 continuously impacts the metal resonance column 14. When the feeding speed of the pump increases, the rotation speed of the rotating shaft 8 increases. Under the elastic force of the telescopic spring 17, one of the sliding seats 18 will move outward. The support rod 12 and the metal impact ball 13 move outward synchronously. The metal impact ball 13 and the metal resonance column 14 are misaligned, the impact frequency decreases, and the vibration amplitude of the hopper 1 decreases synchronously, avoiding the separation of concrete paste and aggregate caused by high-speed vibration.

[0053] Reference Figure 8 and Figure 9 Both support rods 12 are vertically provided with centrifugal sliding holes 19. Two first positioning blocks 20 and two second positioning blocks 21 are fixedly installed on the rotating seat 11. Each of the two first positioning blocks 20 is provided with a first positioning groove, and each of the two second positioning blocks 21 is provided with a second positioning groove. The depth of the second positioning groove is greater than that of the first positioning groove. Both support rods 12 are provided with locking components for locking themselves. Under low speed conditions, the locking components are respectively engaged in the first positioning groove and the second positioning groove to maintain the working position of the impact ball on the outside. After the speed continues to increase, one set of locking components slides upward and disengages from the first positioning groove under centrifugal force. When the speed continues to increase, the other set of locking components slides off the second positioning groove under centrifugal force, so as to realize the adaptive adjustment of vibration intensity with feeding flow rate.

[0054] The locking assembly includes a centrifugal block 22 slidably installed in the centrifugal sliding hole 19, a return spring 23 fixedly installed in the centrifugal sliding hole 19, and two L-shaped positioning rods 39 symmetrically fixedly installed on the centrifugal block 22. One end of the return spring 23 is fixedly connected to the centrifugal block 22. One end of the two L-shaped positioning rods 39 on one support rod 12 is inserted into two first positioning slots, and one end of the two L-shaped positioning rods 39 on the other support rod 12 is inserted into two second positioning slots. When the rotation speed increases and centrifugal force is generated, the centrifugal block 22 slides outward to compress the return spring 23, and the L-shaped positioning rods 39 disengage from their original positioning slots. Under the elastic force of the telescopic spring 17, the sliding seat 18 moves towards one end of the rotating shaft 8. The L-shaped positioning rods 39 on the two support rods 12 are respectively inserted into the first positioning slot and the second positioning slot, so that the two sliding seats 18 can slide at different rotation speeds.

[0055] Reference Figure 10 The metal resonant column 14 has a cylindrical cavity 24 inside. A connecting pipe 25 connected to the cylindrical cavity 24 is installed on the upper surface of the metal resonant column 14. A sound amplification cover 26 is fixedly installed at the upper end of the connecting pipe 25. Multiple thin steel wires 27 are installed inside the cylindrical cavity 24. One end of the multiple thin steel wires 27 is fixed to the inner wall of the cylindrical cavity 24, and the other end is suspended. A metal plate 28 is fixedly installed on the inner wall of the cylindrical cavity 24. The suspended end of the multiple thin steel wires 27 is in contact with the surface of the metal plate 28. When the metal impact ball 13 strikes the metal resonant column 14, the thin steel wires 27 inside the cylindrical cavity 24 repeatedly strike the metal plate 28, producing a warning sound. After being amplified by the sound amplification cover 26, the construction personnel on site can hear it clearly. When the material feeding exceeds the standard and the metal impact ball 13 moves outward and stops striking the metal resonant column 14, the warning sound disappears. The operator can intuitively judge that the pumping flow rate is too high and adjust the conveying speed of the overhead pump in time to avoid concrete segregation.

[0056] Reference Figure 11 Warning seats 29 are fixedly installed at both ends of the rotating shaft 8. A cavity 30 is opened inside the warning seat 29. A support rod 31 is horizontally fixedly installed inside the cavity 30. A rotating seat 32 is rotatably sleeved on the support rod 31. Mounting plates 33 are symmetrically fixedly installed on the rotating seat 32. LED light panels 34 are fixedly installed on both mounting plates 33. A connecting plate 40 is fixedly installed on the lower surface of the rotating seat 32. A counterweight column 35 is fixedly installed on the lower side of the connecting plate 40. The two mounting plates 33 are symmetrically arranged on the connecting plate 40. On the side, the warning seat 29 has multiple square holes 36 equidistantly spaced around its surface. The rotating shaft 8 drives the outer shell of the warning seat 29 to rotate continuously. The counterweight column 35 keeps the rotating seat 32 stationary by its own weight. The LED light panel 34 is fixed in position, and the light shines intermittently through the square holes 36 to form a long-distance flashing light. If the concrete in the hopper 1 is full and submerges the arc-shaped blade 10, the material cannot drive the blade to rotate, the rotating shaft 8 stops rotating, and the flashing light disappears. On-site personnel can promptly detect the risk of overflow and shut down the overhead pump to prevent large-scale blockage of the pipeline.

[0057] Example 3

[0058] Reference Figure 12 A concrete pouring device includes: multiple connecting flanges 37, multiple pouring pipes 38, and the aforementioned concrete diversion device. The multiple connecting flanges 37 are respectively fixedly installed at one end of the multiple pouring pipes 38. The multiple connecting flanges 37 are respectively connected to the bottom of multiple secondary circular chutes 5. During construction, pouring pipes 38 of corresponding lengths are selected according to the height and inclination angle of each sealed chamber in the steel-concrete composite section. The pipeline is sealed and connected through the connecting flanges 37. The concrete flows into the pouring pipes 38 through the secondary circular chutes 5 and reaches the bottom of the chamber directly, avoiding aggregate separation caused by the free fall of concrete from a height and improving the compactness of the pouring at the bottom of the chamber. The flange connection is convenient to install and disassemble, and the appropriate pouring pipes 38 can be quickly replaced according to different chamber specifications.

[0059] In this invention, during construction, the construction personnel carry the complete set of diversion device, clamps, and pouring pipes 38 to the construction position of the steel-concrete arch rib. First, the three primary circular chutes 2 are symmetrically locked to the steel arch diaphragm through clamps, forming a triangular support frame. The hopper 1 is welded and fixed to the top of the primary circular chutes 2, completing the main body load-bearing fixation of the device. No additional independent support structure is required. The secondary material distribution trough 4 and the secondary circular chutes 5 are assembled in sequence. The appropriate length of the pouring pipe 38 is selected according to the depth of each sealed chamber. The pouring pipe 38 is sealed and connected to the bottom end of the secondary circular chutes 5 using the connecting flange 37. All primary control switches 3 and secondary control switches 6 are inserted and closed to shut off all feeding channels.

[0060] Check that the rotating shaft 8 and the arc-shaped blade 10 inside the hopper 1 are free of debris and blockage. Confirm that there is no slurry leakage in the sealed bearing 7. Check that the gap between the metal impact ball 13 and the metal resonance column 14 is normal. Check that the power supply line of the LED light board 34 is intact. Check that the square hole 36 is not blocked by cement slurry. Insert and unplug each of the plate-shaped gate type primary control switch 3 and secondary control switch 6 one by one. Confirm that the gate can be inserted and removed smoothly without jamming. Check that the sealing gaskets at the pipeline flange connection positions are intact and there is no risk of slurry leakage. After confirming that everything is correct, prepare to start the boom pump to transport concrete.

[0061] The concrete pump is started to continuously deliver the mixed concrete into the hopper 1. The falling concrete continuously impacts the arc-shaped blade 10, and the rotating shaft 8 rotates at a constant speed due to the impact force of the material. No external power equipment is required. The rotating seats 11 at both ends of the rotating shaft 8 rotate synchronously. The support rod 12 drives the metal impact ball 13 to periodically strike the metal resonance column 14. The fine steel wire 27 inside the metal resonance column 14 repeatedly hits the metal plate 28 to produce a prompt sound. The sound is amplified by the sound amplifier 26, and the on-site construction personnel can intuitively identify that the device is in normal feeding condition. At the same time, the continuous low-frequency vibration disperses the aggregate and reduces the probability of pipeline blockage.

[0062] On that day, the pump delivery speed increased, the concrete flow rate in hopper 1 increased, and the rotation speed of the rotating shaft 8 increased synchronously. The centrifugal force drove the centrifugal block 22 to slide outward along the centrifugal sliding hole 19. One end of the L-shaped positioning rod 39 disengaged from the first positioning groove, releasing the lock on the sliding seat 18. The sliding seat 18 was pushed outward by the telescopic spring 17, and the metal impact ball 13 and the metal resonance column 14 were misaligned. Since half of the metal impact ball 13 and the metal resonance column 14 were misaligned, the impact frequency decreased, and the vibration amplitude of hopper 1 decreased synchronously. This avoided the separation of aggregate and slurry in the concrete due to continuous strong vibration at high speed, reduced defects such as honeycomb and segregation in the components after pouring, and ensured the workability and molding quality of the concrete.

[0063] As the pump's delivery speed continues to increase, one end of the L-shaped positioning rod 39 on another support rod 12 comes out of the second positioning groove, and another sliding seat 18 slides, causing the metal impact ball 13 to be misaligned with the metal resonance column 14. The metal resonance column 14 is no longer subjected to impact excitation, and the thin steel wire 27 in the inner cavity of the metal resonance column 14 loses vibration excitation and stops reciprocating to scrape the internal metal plate 28. The warning sound that was originally amplified by the sound amplifier cover 26 disappears. On-site construction personnel can intuitively judge that the current feeding speed exceeds the reasonable range through the change in sound, and promptly reduce the pump's delivery flow rate to avoid concrete segregation problems caused by excessive feeding speed and uncontrolled vibration from the source.

[0064] If the conveying flow rate is not reduced in time, the concrete in hopper 1 will gradually accumulate. The continuous accumulation of concrete will submerge the arc-shaped blade 10, and the material will not be able to drive the rotating shaft 8 to rotate. The light on the LED light panel 34 will stop flashing completely, indicating that hopper 1 is about to overflow. At this time, the feed pump should be stopped immediately to visually remind the on-site personnel to stop feeding immediately, prevent the hopper from overflowing and the chutes at all levels from becoming completely blocked, and reduce the extra time spent cleaning the blockages and dealing with the overflow.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
