Specific embodiments

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: As Figures 1-7 shown, the present invention provides a technical solution for a concrete pouring device for subway station construction, which is characterized in that: the concrete pouring device for subway station construction includes a base 1, an internal flow channel 2 is opened in the base 1, a feed bin 3 is installed above the internal flow channel 2, a discharge port 4 is installed on the side of the internal flow channel 2, a discharge pipe 5 is installed at the discharge port 4, a first sleeve 6 is slidably installed in the discharge pipe 5, a second sleeve 7 is slidably installed in the first sleeve 6, a tee joint 8 is installed at the end of the second sleeve 7, a pouring pipe 9 is installed on the tee joint 8, two diversion ports 10 are opened on the pouring pipe 9, the diversion ports 10 are connected to the tee joint 8, three pouring ports 11 are opened on the pouring pipe 9, and pouring joints 12 are installed on all three pouring ports 11.

[0031] When concrete pouring is required, the mixed concrete is injected into the feeding bin 3. The concrete flows from the discharge port 4 along the internal flow channel 2 through the discharge pipe 5, the first sleeve 6 and the second sleeve 7 into the tee joint 8. The concrete flows into the pouring pipe 9 from the two output ports of the tee joint 8 via the diversion port 10. Finally, the concrete flows from the pouring joint 12 of the pouring port 11 to the building surface to be poured. The three pouring joints 12 carry out pouring synchronously, which is applicable to the construction site for large-area pouring, can increase the unit pouring area, thus improving the construction efficiency. Moreover, pouring at three pouring points in the same vertical plane can effectively avoid the problems of excessive local concrete and uneven distribution.

[0032] An electric telescopic rod 13 is installed on the base 1. A connecting column 14 is installed at the end of the electric telescopic rod 13. A fixed semi-ring 15 is installed on the connecting column 14, and the fixed semi-ring 15 is connected to the pouring pipe 9.

[0033] During pouring, the electric telescopic rod 13 slowly extends. When the electric telescopic rod 13 extends, it will push the pouring pipe 9 to move forward synchronously through the connecting column 14 and the fixed semi-ring 15, increasing the area that the pouring can cover. Compared with the traditional pouring method, it does not require workers to move the pouring equipment or pipelines, which can reduce the labor intensity of workers and further improve the construction efficiency.

[0034] The discharge pipe 5 is frustum-shaped, with the end with a larger radius connected to the base 1 and the end with a smaller radius connected to the first sleeve 6.

[0035] When the concrete flows through the discharge pipe 5, the conical discharge pipe 5 will accelerate the concrete, making the concrete flow to the pouring surface faster, reducing the residence time of the concrete in the pipeline and speeding up the construction speed.

[0036] A cleaning component 16 is arranged on the base 1. The contraction of the electric telescopic rod 13 provides driving force for the cleaning component 16, and a measuring component 17 is arranged on the discharge pipe 5.

[0037] As Figures 1-8 shown, the cleaning component 16 includes a cleaning mounting base 1601, a ratchet wheel 1602, a ratchet pawl 1604, a transmission gear 1605, a steering gear 1606, a reciprocating worm 1607, a driven gear 1608, a slider 1609, a limiting column 1610, a first rope hole 1611, a second rope hole 1612, a scraper 1613, a scraper return spring 1614, a pull rope 1615, a main gear 1616, a transmission column 1617, a gear mounting plate 1618, a driving gear 1619, a screw 1620, a push plate 1621, a connecting plate 1622 and a screw return spring 1623;

[0038] A cleaning mounting base 1601 is installed on one side of the base 1 close to the discharge pipe 5. A gear mounting plate 1618 is installed on the cleaning mounting base 1601. A driving gear 1619 is rotatably installed on the gear mounting plate 1618. A screw rod 1620 is concentrically installed on the driving gear 1619. The screw rod 1620 is in threaded cooperation with the driving gear 1619. A main gear 1616 is installed on the cleaning mounting base 1601. The main gear 1616 is meshed with the driving gear 1619. A push plate 1621 is installed at one end of the screw rod 1620 away from the base 1. The push plate 1621 is at the same horizontal height as the pouring pipe 9. A ratchet wheel 1602 is rotatably installed in the cleaning mounting base 1601. The ratchet wheel 1602 is connected to the main gear 1616 through a transmission column 1617. A turntable 1603 is rotatably installed on the lower surface in the cleaning mounting base 1601. The turntable 1603 is concentrically installed with the ratchet wheel 1602. Three ratchet pawls 1604 are rotatably installed in the turntable 1603. The ratchet pawls 1604 and the ratchet wheel 1602 are at the same horizontal height. The outer side of the turntable 1603 has threads. A transmission gear 1605 is rotatably installed on the cleaning mounting base 1601. The transmission gear 1605 is in threaded engagement with the turntable 1603. A steering gear 1606 is rotatably installed on the cleaning mounting base 1601. The steering gear 1606 is meshed with the transmission gear 1605. A reciprocating worm 1607 is rotatably installed on the cleaning mounting base 1601. A driven gear 1608 is installed on the reciprocating worm 1607. The driven gear 1608 is meshed with the steering gear 1606. A slider 1609 is slidably installed on the reciprocating worm 1607. Scrapers 1613 are slidably installed at both ends in the pouring pipe 9. The scrapers 1613 are connected to the slider 1609 through a pull rope 1615.

[0039] After pouring is completed, the electric telescopic rod 13 drives the pouring pipe 9 to contract and reset. When the pouring pipe 9 moves back towards the base 1, it pushes the push plate 1621 to drive the screw 1620 to move towards the side close to the base 1. Since the screw 1620 is in threaded cooperation with the driving gear 1619, the movement of the screw 1620 drives the driving gear 1619 to rotate. The driving gear 1619 drives the main gear 1616 to rotate due to gear meshing. The main gear 1616 drives the ratchet 1602 to rotate forward through the transmission column 1617. When the ratchet 1602 rotates forward, the pawl 1604 cooperates with the ratchet 1602. The rotation of the ratchet 1602 drives the turntable 1603 to rotate synchronously. When the turntable 1603 rotates, it drives the transmission gear 1605 to rotate through gear meshing. The transmission gear 1605 drives the driven gear 1608 to rotate through the steering gear 1606. When the driven gear 1608 rotates, it drives the reciprocating worm 1607 to rotate synchronously. The rotation of the reciprocating worm 1607 drives the slider 1609 to slide towards the end close to the base 1 on the reciprocating worm 1607. When the slider 1609 slides, it pulls the scraping plate 1613 towards the center of the pouring pipe 9 through the pull rope 1615. The scraping plate 1613 cleans the residual concrete remaining on the inner wall of the pouring pipe 9, keeps the inside of the pipe clean, reduces the residue and solidification of concrete, and extends the service life.

[0040] A first rope hole 1611 is opened on the pouring pipe 9. The first rope hole 1611 is located at the middle position of the pouring pipe 9. A second rope hole 1612 is opened on the cleaning mounting seat 1601. A limiting column 1610 is installed inside the cleaning mounting seat 1601. The pull rope 1615 passes through the first rope hole 1611 and the second rope hole 1612, and bypasses the limiting column 1610 and is connected to the slider 1609.

[0041] The pull rope 1615 passes out of the pouring pipe 9 from the first rope hole 1611 and enters the cleaning mounting seat 1601 from the second rope hole 1612. Inside the cleaning mounting seat 1601, the pull rope 1615 is on the side of the limiting column 1610 away from the turntable 1603, preventing the pull rope 1615 from rubbing against the turntable 1603 and extending the service life of the pull rope 1615.

[0042] The scraping plate 1613 is connected to the end of the pouring pipe 9 through a scraping plate return spring 1614. A connecting plate 1622 is installed at one end of the screw 1620 close to the base 1. The connecting plate 1622 is connected to the gear mounting plate 1618 through a screw return spring 1623.

[0043] When the electric telescopic rod 13 contracts, the scraper return spring 1614 elongates under the pulling force of the pull rope 1615. When the electric telescopic rod 13 finishes contracting and the slider 1609 moves to the end of the reciprocating worm 1607 close to the base 1, and the scraper 1613 reaches the middle of the pouring pipe, the electric telescopic rod 13 no longer provides driving force. At this time, the scraper 1613 is pulled by the scraper 1613 return spring, and the scraper 1613 moves back to both ends of the pouring pipe 9. The scraper 1613 pulls the slider 1609 to move along the reciprocating worm 1607 to the side away from the base 1 through the pull rope 1615. Since the surface of the reciprocating worm 1607 has two reverse thread lines, when the slider 1609 moves along the reciprocating worm 1607 to the side away from the base 1, the rotation direction of the reciprocating worm 1607 driven is the same as the rotation direction when the electric telescopic rod 13 contracts. Through each transmission part, the rotation of the turntable 1603 is in the same direction as before, and the ratchet 1602 will not be driven to rotate;

[0044] When the electric telescopic rod 13 contracts, the screw return spring 1623 is stretched. When the electric telescopic rod 13 elongates, the screw return spring 1623 releases elastic force to drive the screw 1620 to reset. At this time, the screw 1620 drives the ratchet 1602 to reverse through each transmission part. The ratchet 1602 and the pawl 1604 are disengaged, and the ratchet 1602 will not drive the turntable 1603 to rotate;

[0045] Therefore, only when the electric telescopic rod 13 contracts, the ratchet 1602 and the pawl 1604 will cooperate, and the scraper 1613 can be driven to clean the pouring pipe 9. After the electric telescopic rod 13 finishes contracting, the scraper return spring 1614 drives the scraper 1613 to reset. When the electric telescopic rod 13 elongates, the screw return spring 1623 drives the screw 1620 to reset. When the scraper 1613 and the screw 1620 reset, the ratchet 1602 and the pawl 1604 are disengaged, and the reset of the scraper 1613 and the screw 1620 does not affect each other, and at the same time prepares for the next cleaning, which can ensure the normal operation of the equipment.

[0046] As Figures 1-4 、 Figure 5 and Figure 9 shown, the measuring component 17 includes a mounting ring 1701, a measuring plate 1702, an angle sensor 1703 and a data processor 1704;

[0047] One end of the first sleeve 6 close to the base 1 is provided with a mounting ring 1701. The mounting ring 1701 is rotatably provided with a measuring plate 1702. An angle sensor 1703 is installed on the rotating column of the measuring plate 1702. A data processor 1704 is installed on the base 1. The angle sensor 1703 is electrically connected to the data processor 1704, and the electric telescopic rod 13 is electrically connected to the data processor 1704.

[0048] When the concrete flows through the discharge pipe 5 towards the first sleeve 6, it will push the measuring plate 1702 to rotate. The angle sensor 1703 transmits the electrical signal generated by the rotation angle back to the data processor 1704. The data processor 1704 feeds back the unit flow rate of the concrete in the first sleeve 6 according to the received electrical signal, and controls the elongation speed of the electric telescopic rod 13 according to the flow rate, which can make the pouring of the concrete more uniform, improve the pouring quality and reduce the workload of workers at the same time.

[0049] Working principle of the present invention:

[0050] When concrete pouring is required, the mixed concrete is injected into the feeding bin 3. The concrete flows from the discharge port 4 along the internal flow channel 2 through the discharge pipe 5, the first sleeve 6 and the second sleeve 7 into the three-way joint 8. The concrete flows into the pouring pipe 9 from the two output ports of the three-way joint 8 via the diversion port 10. Finally, the concrete flows from the pouring joint 12 of the pouring port 11 to the building surface to be poured. The three pouring joints 12 carry out pouring synchronously, which is applicable to the construction site for large-area pouring, can increase the unit pouring area, thereby improving the construction efficiency, and pouring at three pouring points in the same vertical plane can effectively avoid the problems of excessive local concrete and uneven distribution.

[0051] During the pouring process, the electric telescopic rod 13 slowly extends. When the electric telescopic rod 13 extends, it will push the pouring pipe 9 to move forward synchronously through the connecting column 14 and the fixed semi-ring 15, increasing the area that can be covered by the pouring. Compared with the traditional pouring method, it does not require workers to move the pouring equipment or pipelines, which can reduce the labor intensity of workers and further improve the construction efficiency.

[0052] When the concrete flows through the discharge pipe 5, the conical discharge pipe 5 will accelerate the concrete, making the concrete flow towards the pouring surface faster, reducing the residence time of the concrete in the pipeline and accelerating the construction speed.

[0053] After pouring is completed, the electric telescopic rod 13 will drive the pouring pipe 9 to contract and reset. When the pouring pipe 9 moves and resets towards the base 1, it will push the push plate 1621 to drive the screw 1620 to move towards the side close to the base 1. Since the screw 1620 is in threaded cooperation with the driving gear 1619, the movement of the screw 1620 will drive the driving gear 1619 to rotate. The driving gear 1619 drives the main gear 1616 to rotate due to gear meshing. The main gear 1616 drives the ratchet 1602 to rotate forward through the transmission column 1617. When the ratchet 1602 rotates forward, the pawl 1604 forms a cooperation with the ratchet 1602. The rotation of the ratchet 1602 will drive the turntable 1603 to rotate synchronously. When the turntable 1603 rotates, it drives the transmission gear 1605 to rotate through gear meshing. The transmission gear 1605 drives the driven gear 1608 to rotate through the steering gear 1606. When the driven gear 1608 rotates, it will drive the reciprocating worm 1607 to rotate synchronously. The rotation of the reciprocating worm 1607 will drive the slider 1609 to slide towards the end close to the base 1 on the reciprocating worm 1607. When the slider 1609 slides, it will pull the scraping plate 1613 towards the center of the pouring pipe 9 through the pull rope 1615. The scraping plate 1613 will clean the residual concrete remaining on the inner wall of the pouring pipe 9, keep the inside of the pipe clean, reduce the residue and solidification of concrete, and extend the service life.

[0054] The pull rope 1615 passes through the pouring pipe 9 from the first rope hole 1611 and enters the cleaning mounting seat 1601 from the second rope hole 1612. Inside the cleaning mounting seat 1601, the pull rope 1615 is on the side of the limit post 1610 away from the turntable 1603, preventing the pull rope 1615 from rubbing against the turntable 1603 and extending the service life of the pull rope 1615.

[0055] When the electric telescopic rod 13 contracts, the scraping plate return spring 1614 elongates under the tension of the pull rope 1615. When the electric telescopic rod 13 finishes contracting and the slider 1609 moves to the end of the reciprocating worm 1607 close to the base 1 and the scraping plate 1613 reaches the middle of the pouring pipe, the electric telescopic rod 13 no longer provides driving force. At this time, the scraping plate 1613 is under the tension of the scraping plate 1613 return spring, and the scraping plate 1613 moves back towards both ends of the pouring pipe 9. The scraping plate 1613 pulls the slider 1609 to move along the reciprocating worm 1607 towards the side away from the base 1 through the pull rope 1615. Since the surface of the reciprocating worm 1607 has two reverse thread lines, when the slider 1609 moves along the reciprocating worm 1607 towards the side away from the base 1, the rotation direction of the reciprocating worm 1607 driven is the same as the rotation direction when the electric telescopic rod 13 contracts. Through each transmission part, the rotation of the turntable 1603 is the same as the previous rotation direction and will not drive the ratchet 1602 to rotate;

[0056] When the electric telescopic rod 13 contracts, the screw reset spring 1623 is stretched. When the electric telescopic rod 13 extends, the screw reset spring 1623 releases elastic force to drive the screw 1620 to reset. At this time, the screw 1620 drives the ratchet 1602 to reverse through each transmission part. The ratchet 1602 and the pawl 1604 are disengaged, and the ratchet 1602 will not drive the turntable 1603 to rotate;

[0057] Therefore, only when the electric telescopic rod 13 contracts, the ratchet 1602 and the pawl 1604 will cooperate to drive the scraper 1613 to clean the pouring pipe 9. After the electric telescopic rod 13 finishes contracting, the scraper reset spring 1614 drives the scraper 1613 to reset. When the electric telescopic rod 13 extends, the screw reset spring 1623 drives the screw 1620 to reset. When the scraper 1613 and the screw 1620 reset, the ratchet 1602 and the pawl 1604 are disengaged, and the reset of the scraper 1613 and the screw 1620 does not affect each other, and at the same time prepares for the next cleaning, which can ensure the normal operation of the equipment.

[0058] When the concrete flows from the discharge pipe 5 to the first sleeve 6, it will push the measuring plate 1702 to rotate. The angle sensor 1703 transmits the electrical signal generated by the rotation angle back to the data processor 1704. The data processor 1704 feeds back the unit flow rate of the concrete in the first sleeve 6 according to the received electrical signal, and controls the extension speed of the electric telescopic rod 13 according to the flow rate, which can make the pouring of the concrete more uniform, improve the pouring quality and reduce the workload of workers.

[0059] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
