Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete pouring construction, and in particular to a concrete pouring device. BACKGROUND

[0002] In the process of building construction, pouring operation is a key step of pouring the prepared concrete into the completed formwork. For high-rise buildings or pouring operation in deep piles, a combined funnel and pouring pipe system is usually used to adapt to the large pouring height or depth requirements. During the pouring operation, the pouring pipe needs to withstand the huge pressure from the top concrete pouring and its own weight. Some concrete pouring devices support the pouring pipe by setting a support frame to make the support pipe stable, but this design still has certain limitations and deficiencies.

[0003] On the one hand, some support frames lack lateral limiting structures, which may cause the instability of the support frame due to the vibration caused by the falling of concrete during the pouring operation, not only increasing the safety risk of the operation, but also causing accidental collision between the pouring pipe and the cavity wall of the formwork, damaging the pipeline. On the other hand, during the process of gradually moving the pouring pipe upward with the progress of the pouring operation, the flap (or gate) for controlling the flow of concrete is flipped to both sides due to the lack of a reset mechanism, which not only interrupts the pouring process, but also may cause concrete leakage, causing unnecessary trouble and cost increase for construction.

Detailed Implementation

[0026] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0027] During the pouring operation, some concrete pouring devices use support frames to stabilize the pouring pipe. However, this design still has certain limitations and shortcomings. Firstly, some support frames lack lateral restraint structures, which can cause instability in the support frame placement due to vibrations from falling concrete during pouring. This not only increases safety risks but may also lead to accidental collisions between the pouring pipe and the formwork cavity wall, damaging the pipe. Secondly, as the pouring pipe gradually moves upwards during the pouring operation, the flaps (or gates) used to control the concrete flow may flip to either side due to the lack of a reset mechanism. This can interrupt the pouring process and potentially cause concrete leakage, resulting in unnecessary trouble and increased costs for construction.

[0028] To address the problem of poor stability in concrete pouring devices, this application provides a concrete pouring device, see [link to relevant documentation]. Figs. 1-3 The device includes: a support frame assembly 1, a limit frame assembly 2, a flip plate 4, a funnel 6, and an injection pipe assembly 7.

[0029] The two ends of the support frame assembly 1 are slidably connected to the limit frame assembly 2. The support frame assembly 1 is provided with a column cavity 17. The limit frame assembly 2 includes a sliding frame and a limit stand 23. One end of the sliding frame is provided in the column cavity 17 so that the sliding frame can slide along the column cavity 17.

[0030] The spring 15 is sleeved on the outer side of the sliding frame, one end of the spring 15 is connected with the sliding frame, and the other end of the spring 15 abuts against the end face of the support frame assembly 1. In some embodiments, one end of the spring 15 can be fixed with the end of the sliding frame. By arranging the spring 15, when the spring 15 is in a compressed state, the reverse clamping force can be provided for the limiting frame assembly 2.

[0031] The end, away from the column cavity 17, of the sliding frame is connected with the limiting stand 23. The limiting stand 23 can be a rectangular frame structure and is parallel to the pouring pipe assembly 7. When pouring concrete, the pouring pipe assembly 7 is inserted into the inside of the pouring cavity, the support frame assembly 1 is placed on the pouring cavity, and the limiting stand 23 abuts against the outside of the pouring cavity through the spring 15. Thus, the support frame assembly 1 is clamped to the pouring cavity under the action of the spring 15 and the limiting stand 23, so as to reduce the probability of shaking of the pouring device and improve the stability of the device.

[0032] One end of the turnover plate 4 is hinged with the support frame assembly 1, so that the turnover plate 4 can be opened or closed. The other end of the turnover plate 4 is provided with a limiting hole 41. In some embodiments, the limiting hole 41 can be a semicircular hole. Two turnover plates 4 are symmetrically arranged on the top surface of the support frame assembly 1, so that the two limiting holes 41 can form a complete circular hole. The bottom of the funnel 6 is detachably connected with the top of the pouring pipe assembly 7. The pouring pipe assembly 7 penetrates through the limiting hole 41 and is limited by the limiting hole 41 after being inserted into the pouring cavity. The turnover plate 4 can support the funnel 6 and clamp the top of the pouring pipe assembly 7 at the same time, so that the pouring pipe assembly 7 is positioned. Thus, the probability of shaking of the pouring device is reduced and the stability of the device is improved.

[0033] The pouring device provided in the application provides elastic force for the limiting frame assembly 2 by arranging the limiting frame assembly 2 at both ends of the support frame assembly 1 and arranging the spring 15 on the limiting frame assembly 2. The limiting frame assembly 2 can be automatically retracted after being extended and tightly abut against the side wall of the pouring cavity, so as to reduce the probability of shaking of the pouring device and improve the stability of the device.

[0034] Referring again to Fig. 2 , the support frame assembly 1 comprises a connecting pipe 12 and a side column 13. The support frame assembly 1 can be a rectangular frame structure. The connecting pipe 12 is arranged between two parallel side columns 13 and is arranged at the two ends of the two side columns 13, respectively. The two connecting pipes 12 and the two side columns 13 are sequentially connected. In some embodiments, the connecting pipe 12 and the side column 13 can be rectangular pipes and are fixed by welding. The side column 13 can also be a long rectangular column. The column cavity 17 is arranged in the side column 13. The end, away from the stop block 16, of the spring 15 abuts against the end face of the side column 13, so that the spring 15 can be limited in the column cavity 17. The turnover plate 4 is hinged with the top surface of the side column 13 through the hinge 8.

[0035] The sliding frame comprises a crossbar 21 and sliding rods 22 arranged at both ends of the crossbar 21, and it can be understood that the sliding frame has a U-shaped structure. In order to facilitate the installation of the spring 15, the crossbar 21 and the sliding rod 22 can be cylindrical tubes. The end of the sliding rod 22 away from the crossbar 21 is arranged in the column cavity 17, and the sliding rod 22 is in sliding connection with the side column 13 through the column cavity 17. When the crossbar 21 is pulled outward, the spring 15 is compressed, and a reverse elastic force is generated, so that the limiting stand 23 can clamp the outer side of the perfusion cavity to stabilize the perfusion device. The column cavity 17 is also provided with a stop block 16, which can be welded to the side column 13. When the external force of the spring 15 is removed, the sliding rod 21 quickly rebounds, and the sliding rod 22 is limited by the stop block 16 through the arrangement of the stop block 16.

[0036] The limiting stand assembly 2 further comprises an inclined stand 24, the top of the inclined stand 24 is connected with the bottom of the limiting stand 23, and the inclined stand 24 can also be a rectangular frame structure. The bottom of the inclined stand 24 is inclined away from the perfusion cavity. When the perfusion device is placed downward, the bottom of the inclined stand 24 first contacts the outer side of the perfusion cavity. As the perfusion device continues to move downward, the sliding frame automatically slides outward, compresses the spring 15, and finally makes the limiting stand 23 abut against the outer side wall of the perfusion cavity to clamp the perfusion cavity.

[0037] The limiting stand assembly 2 further comprises a non-slip pad 10 arranged on the side of the limiting stand 23 close to the perfusion cavity. The non-slip pad 10 can increase the friction between the limiting stand 23 and the outer side wall of the perfusion cavity. When the perfusion tube assembly 7 rises, the probability of displacement of the limiting stand assembly 2 and the support frame assembly 1 can be further reduced, and the stability of the perfusion device can be improved.

[0038] The top surface of the turnover plate 4 is provided with an elastic sheet 5, which has an arc-shaped structure and can be made of a metal material such as 65Mn that has elasticity. The central angle of the arc-shaped structure of the elastic sheet 5 is greater than or equal to 90°. When the turnover plate 4 is accidentally turned upward, the elastic sheet 5 collides with the support frame assembly 1, so that the turnover plate 4 rebounds and automatically resets.

[0039] The perfusion tube assembly 7 comprises at least one perfusion tube 71 and a sleeve ring 72. The bottom of the funnel 6 is detachably connected with the top of the perfusion tube 71 through the sleeve ring 72. The perfusion tube 71 is limited by the sleeve ring 72 at the top, and adjacent two perfusion tubes 71 are detachably connected through the sleeve ring 72. In some embodiments, a connecting hole 9 can be arranged on the sleeve ring 72, and the funnel 6 and the perfusion tube 71 are fixed to the sleeve ring 72 by bolts respectively. The radius of the limiting hole 41 is the same as the radius of the perfusion tube 71, so that the perfusion tube 71 can be clamped. The radius of the limiting hole 41 is smaller than the radius of the sleeve ring 72, so that the perfusion tube 71 can be limited by the sleeve ring 72 at the top.

[0040] The top of the sleeve ring 72 is provided with a slope, which is circumferentially arranged on the sleeve ring 72, and the inclination angle of the slope is greater than or equal to 30°. By arranging the slope on the top of the sleeve ring 72, when the pouring pipe assembly 7 rises, the pouring pipe 71 inside the pouring cavity moves upward, and the slope of the sleeve ring 72 connected with the pouring pipe 71 first contacts the turnover plate 4, so that the pouring pipe 71 can be conveniently taken out of the pouring cavity, and the turnover plate 4 will not be turned over by a large angle.

[0041] From the above technical solutions, the embodiment of the present application provides a concrete pouring device, which comprises a support frame assembly 1, a limiting frame assembly 2, a turnover plate 4, a funnel 6 and a pouring pipe assembly 7. The two ends of the support frame assembly 1 are respectively connected with the limiting frame assembly 2 in a sliding manner, a column cavity 17 is arranged in the support frame assembly 1, the limiting frame assembly 2 comprises a sliding frame and a limiting vertical frame 23, one end of the sliding frame is arranged in the column cavity 17, and the other end is connected with the limiting vertical frame 23. A spring 15 is arranged in the column cavity 17, the spring 15 is sleeved on the outer side of the sliding frame, one end of the spring 15 is connected with the sliding frame, and the other end abuts against the end face of the support frame assembly 1. The limiting vertical frame 23 abuts against the outer side of the pouring cavity through the spring 15. One end of the turnover plate 4 is hinged to the support frame assembly 1, the other end of the turnover plate 4 is provided with a limiting hole 41, and two turnover plates 4 are symmetrically arranged on the top surface of the support frame assembly 1. The bottom of the funnel 6 is detachably connected with the top of the pouring pipe assembly 7, and the pouring pipe assembly 7 is limited by the limiting hole 41 after penetrating through the limiting hole 41. By arranging the limiting frame assembly 2 at the two ends of the support frame assembly 1 and arranging the spring 15 on the limiting frame assembly 2, the spring force is provided for the limiting frame assembly 2, so that the limiting frame assembly 2 can be automatically retracted after being extended and tightly abut against the side wall of the pouring cavity, the probability of shaking of the pouring device is reduced, and the stability of the device is improved.
