Description

A concrete auxiliary pouring device Technical Field

[0001] The present application relates to the technical field of building pouring, and in particular to a concrete auxiliary pouring device. Background Art

[0002] In the construction of buildings that mainly use reinforced concrete structures, concrete is transported to the steel skeleton and poured into the formwork through a concrete placing boom to form a floor slab building structure.

[0003] When pouring concrete, there are certain rigid regulations on the height of the discharge pipe. If the discharge pipe is too high, a segregation layer will easily form during pouring, affecting the pouring effect. If the discharge pipe is too low, the concrete will not be poured open, and the concrete used during pouring needs to be continuously stirred.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below with reference to Figures 1-4.

[0035] The embodiment of the present application discloses a concrete auxiliary pouring device.

[0036] As shown in Figure 1, the concrete auxiliary pouring device includes a base plate 1, a mixing barrel 2, a lifting mechanism 3, a support frame 4 and a feeding and stirring mechanism 5. The mixing barrel 2 is connected to the base plate 1 through the lifting mechanism 3. The feeding and stirring mechanism 5 is arranged on the top of the mixing barrel 2. The support frame 4 is arranged on the base plate 1. A support groove for setting the mixing barrel 2 is provided on the support frame 4. The support groove can protect the mixing barrel 2 and prevent the mixing barrel 2 from tipping over.

[0037] As shown in FIG1 , a discharge pipe 201 is provided on one side of the mixing barrel 2 . The discharge pipe 201 is used to be connected to a discharge pump. The discharge pump can pump out the concrete in the mixing barrel 2 for pouring.

[0038] During pouring, the base plate 1 can be placed on the mobile end of a concrete placing boom, which can then pull the auxiliary concrete pouring device to change the position of the discharge pipe 201. When pouring in areas where the concrete placing boom cannot reach, multiple universal wheels 101 can be installed at the bottom of the base plate 1, along with a push handle 102 on one side. In this embodiment, there are four universal wheels 101, allowing workers to push the auxiliary concrete pouring device with the push handle 102 to change the position of the discharge pipe 201.

[0039] During pouring, the height of the discharge pipe 201 can be changed by the lifting mechanism 3 .

[0040] As shown in Figures 1 and 2, the lifting mechanism 3 includes a pusher 301 and an elastic member 302. The body of the pusher 301 is fixedly connected to the base plate 1. The pusher 301 is vertically arranged and its output end is drive-connected to the mixing barrel 2. One end of the elastic member 302 is fixedly connected to the base plate 1, and the other end of the elastic member 302 is fixedly connected to the outer bottom wall of the mixing barrel 2. There are multiple elastic members 302, and the multiple elastic members 302 are evenly spaced around the circumference of the pusher 301. The pusher 301 can be an electric push rod or a cylinder, and the elastic member 302 can be a spring or a spring. In this embodiment, an electric push rod is used as the pusher 301, and a spring is used as the elastic member 302, and the number of elastic members 302 is four.

[0041] During the pouring process, the pusher 301 is controlled to operate, and the reciprocating movement of the output end of the pusher 301 can drive the mixing drum 2 to reciprocate along with the output end of the pusher 301. When the output end of the pusher 301 is extended to its maximum length, the elastic member 302 is in a compressed state. At this time, the elastic member 302 can exert an upward force on the mixing drum 2, sharing a portion of the force exerted by the mixing drum 2 on the pusher 301. When the output end of the pusher 301 is retracted, the elastic member 302 is further compressed. The force used to overcome the contraction of the elastic member 302 is less than the weight of the mixing drum 2 when the mixing drum 2 is fully loaded. Therefore, during this process, the elastic member 302 can still share a portion of the force exerted by the mixing drum 2 on the pusher 301, preventing the pusher 301 from bearing excessive force for a long time, which would reduce its service life. When the output end of the push member 301 extends, the elastic member 302 will be released, and the auxiliary push member 301 will push the mixing barrel 2 away from the main body of the push member 301, reducing the force that the push member 301 needs to apply to the mixing barrel 2, and avoiding the push member 301 needing to apply too much force, resulting in a shortened service life.

[0042] During pouring, concrete can be injected into the mixing barrel 2 through the feeding and stirring mechanism 5 , and the concrete in the mixing barrel 2 is stirred at the same time to prevent the concrete in the barrel from plasticizing and solidifying.

[0043] As shown in Figures 2 and 3, the feeding stirring mechanism 5 includes a cover plate 501 and a stirring rod 502. The cover plate 501 is arranged at the barrel mouth of the stirring barrel 2, can rotate around its own axis and is rotatably connected to the conveying stirring barrel 2. The stirring rod 502 is located at the central axis position of the cover plate 501 and passes through the cover plate 501. When the cover plate 501 rotates, the stirring rod 502 can rotate together with the cover plate 501.

[0044] To feed concrete into the mixing drum 2, the mixing rod 502 is provided with a feed channel. A feed port 503 of the feed channel is located at the top of the mixing rod 502, and a discharge port 504 of the feed channel is located on the side of the mixing rod 502 within the mixing drum 2. Concrete can enter the feed channel through the feed port 503 and exit the feed channel through the discharge port 504, entering the mixing drum 2. Since the mixing rod 502 will remain in a rotating state driven by the cover plate 501 during actual use, the mixing rod 502 may also be provided with a connecting portion 5031 that is capable of rotating about its own axis and is rotatably connected to the feed port 503. In this embodiment, the connecting portion 5031 is a tubular structure that extends through the feed port 503, with a bearing disposed between the connecting portion 5031 and the feed port 503. Various other connection methods are possible for the connecting portion 5031 and the feed port 503, and this disclosure is not limited thereto. The stirring rod 502 is connected to the delivery pipe via the connection portion 5031 , which ensures that when the stirring rod 502 rotates, the delivery pipe and the connection portion 5031 are relatively fixed, thereby stabilizing the concrete transmission process.

[0045] In order to feed concrete into the mixing barrel 2 and stir the concrete in the mixing barrel 2, a first stirring paddle 513 is further provided on the stirring rod 502. The first stirring paddle 513 is located below the discharge port 504 in the vertical direction. During actual use, the cover plate 501 can drive the stirring rod 502 to rotate together, so that the first stirring paddle 513 fixedly connected to the stirring rod 502 stirs the concrete in the mixing barrel 2.

[0046] As shown in Figures 2 and 4, in order to expand the stirring range of the feeding stirring mechanism 5 and avoid the concrete far away from the first stirring paddle 513 not being fully stirred due to the stirring range being too small, resulting in a decrease in the hardness of the concrete after pouring, the feeding stirring mechanism 5 can also include a planetary gear system.

[0047] The planetary gear system includes a planetary carrier 508, a sun gear 505, a planetary gear 506 and an outer ring gear 507. The planetary carrier 508 has a planetary disk 5081 and a planetary gear shaft 5082. The central axis of the planetary disk 5081 is provided with an avoidance hole 5083 for the stirring rod 502 to pass through. The inner side wall of the mixing barrel 2 is provided with a planetary groove that matches the planetary disk 5081, so that the planetary disk 5081 can rotate around its own axis and be rotatably connected to the mixing barrel 2. The planetary gear 506 can rotate around its own axis and be rotatably connected to the planetary gear shaft 5082. The sun gear 505 is fixedly connected to the stirring rod 502 and is located above the discharge port 504 in the vertical direction. In this embodiment, the sun gear 505 is integrally formed with the stirring rod 502. The outer ring gear 507 can be fixedly connected to the mixing barrel 2, or it can be integrally formed with the mixing barrel 2 as in the present embodiment. The planetary gear 506 is meshed with the outer ring gear 507 and the sun gear 505 at the same time. Planetary gear trains can be combined in various ways, depending on the input, output, and deadlock ends. In this embodiment, since the mixing drum 2 cannot rotate, the outer ring gear 507 integrally formed with the mixing drum 2 serves as the deadlock end. Since the cover plate 501 can rotate about its own axis, simultaneously driving the stirring rod 502 to rotate, the outer ring gear 507 integrally formed with the stirring rod 502 serves as the input end. Since the input and deadlock ends are already determined, the planet carrier 508 serves as the output end. To enable the output end of the planetary gear train to stir the concrete, a second stirring paddle 514 is provided on the side of the planetary gear shaft 5082 away from the planetary disc 5081.

[0048] During actual use, the cover plate 501 can drive the stirring rod 502 to rotate together, thereby driving the planetary carrier 508 of the planetary gear system to rotate about its own axis, causing the planetary gear shaft 5082 of the planetary carrier 508 to rotate about the central axis of the sun gear 505, so that the second stirring paddle 514 fixedly connected to the planetary gear shaft 5082 can stir the concrete in the mixing drum 2. The planetary gear system can have multiple planetary gears 506, and the number of planetary gear shafts 5082 is the same as the number of planetary gears 506. In order to fully stir the concrete in the mixing drum 2 while not occupying excessive space in the mixing drum 2, in this embodiment, there are three planetary gears 506.

[0049] As shown in Figure 2, in order to avoid concrete sticking to the barrel wall and barrel bottom of the mixing barrel 2 during the mixing process, the feeding and mixing mechanism 5 also includes an inner wall scraper 509, and the inner wall scraper 509 includes a barrel wall scraper 5091 and a barrel bottom scraper 5092. The barrel bottom scraper 5092 is arranged close to the barrel bottom of the mixing barrel 2, and one end of the barrel bottom scraper 5092 is fixedly connected to the bottom end of the stirring rod 502, and the other end of the barrel bottom scraper 5092 is connected to the barrel wall scraper 5091, so that the barrel wall scraper 5091 can be close to the barrel wall of the mixing barrel 2.

[0050] During actual use, the cover plate 501 can drive the stirring rod 502 to rotate together, thereby driving the inner wall scraper 509 to rotate around the central axis of the cover plate 501. During rotation, the barrel wall scraper 5091 can scrape the barrel wall of the mixing barrel 2, and the barrel bottom scraper 5092 can scrape the barrel bottom of the mixing barrel 2, thereby cleaning the barrel wall and barrel bottom of the mixing barrel 2.

[0051] As shown in Figure 1, in order to provide power to the feeding and stirring mechanism 5, the feeding and stirring mechanism 5 also includes a motor 510. The body of the motor 510 is fixedly connected to the bottom plate 1. The output end of the motor 510 is provided with a first gear 511. The cover plate 501 is coaxially fixedly connected to the outside with a second gear 512. In this embodiment, the second gear 512 and the cover plate 501 are integrally formed, and the first gear 511 is meshed with the second gear 512.

[0052] In actual use, when the motor 510 starts operating, it drives the first gear 511 to rotate. Due to the meshing action of the first gear 511 and the second gear 512, the second gear 512 and the cover plate 501 begin to rotate simultaneously. Because the mixing drum 2 will change its vertical position due to the influence of the pusher 301 during the process of the motor 510 driving the first gear 511 to rotate, thereby causing the second gear 512 to change its vertical position, the thickness of the first gear 511 should be greater than the thickness of the second gear 512, so that the second gear 512 can always mesh with the first gear 511 during the process of vertical movement.

[0053] The implementation principle of a concrete auxiliary pouring device in an embodiment of the present application is: before pouring, the delivery pipe is connected to the connection part 5031 of the stirring rod 502, and the motor 510 is started after the delivery pipe starts to transport concrete into the mixing barrel 2. As the stirring rod 502 starts to rotate under the drive of the motor 510, the discharge port 504 on the stirring rod 502 also rotates around the axis direction of the stirring rod 502, so that the concrete can enter the mixing barrel 2 evenly, avoiding the situation where there is too much concrete on one side of the mixing barrel 2 and too little concrete on the other side.

[0054] As the stirring rod 502 starts to rotate under the drive of the motor 510, the sun gear 505 integrally formed with the stirring rod 502 also rotates therewith, so the planetary carrier 508 in the same planetary gear system also starts to rotate. At this time, the first stirring paddle 513 and the second stirring paddle 514 start to stir the concrete in the mixing barrel 2.

[0055] At this point, the worker can turn on the discharge pump connected to the discharge pipe 201 to pump out concrete for pouring. During the pouring process, the worker can use the concrete placing machine to pull the auxiliary concrete pouring device to change the horizontal position of the discharge pipe 201, or use the push handle 102 to push the auxiliary pouring device to change the horizontal position of the discharge pipe 201. At the same time, the worker can also control the electric push rod to drive the mixing drum 2 to move in the vertical direction to change the vertical position of the discharge pipe 201.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
