Description

Technical Field

[0001] This utility model relates to the field of concrete pouring equipment technology, and in particular to a concrete placing device for pouring building concrete. Background Technology

[0002] Concrete pouring placing devices are key equipment for the precise delivery and distribution of concrete in building construction. Their core function is to solve the problem of efficient transfer and uniform distribution of concrete from transportation equipment to the pouring work surface. Common types include concrete placing booms and placing arms, which typically include a slewing mechanism, telescopic boom, and placing hose, allowing for flexible adjustment of the placing radius and angle. For example, the existing Chinese utility model patent CN207017271U, entitled "Concrete Placing System for Basement Construction," describes a concrete placing boom that includes a vertically installed steel support in the foundation pit and a horizontally rotatable steel crossbeam mounted on top of the steel support. One end of the crossbeam serves as the outlet for the placing pipe, and the front end of the placing pipe is connected to a downward-extending pumping rubber discharge mechanism. The placing pipe is arranged downwards along the steel support at its rear end and connected to the concrete conveying pipe. During operation, the placing machine needs to be supported on the reference surface by the bottom support frame and outriggers. However, since the steel cross frame has a certain length, it is easy to cause instability in the support when rotating. Therefore, in most cases, existing concrete pouring placing devices use multiple anchor cables to fix the steel support on the reference surface or use ground anchors to fix it. Therefore, it is necessary to open holes in the reference surface, making the fixing and transfer operation of the entire placing device inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a concrete placing device for building concrete pouring that does not require drilling holes in the reference surface and can be quickly fixed to the steel mesh by adjustable fastening hooks, thereby improving the convenience of installation and transfer and effectively solving the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A concrete placing device for pouring concrete in construction includes a column, a base fixedly connected to the bottom of the column, a support platform, multiple support beams fixedly connected to the outer circumference of the support platform, multiple side plates movably connected to both sides of the support beams, multiple positioning blocks fixedly connected to one side of each side plate, and fastening hooks movably connected between adjacent positioning blocks, multiple sliders fixedly connected to the side of the side plate opposite to the positioning blocks, connecting blocks fixedly connected between the sliders, adjusting bolts movably connected within the connecting blocks, a feed pipe fixedly connected to the outer side of the column, a rotating frame rotatably connected to the top of the column, a cantilever fixedly connected to the outer side of the rotating frame, a conveying pipe fixedly connected to the top of the rotating frame and the top of the cantilever, and a placing pipe rotatably connected to the end of the conveying pipe away from the rotating frame via a rotary joint.

[0005] As a further preferred embodiment of this utility model, one end of the feed pipe extends through the column to the top of the column and communicates with the inner cavity of the rotating frame, thereby enabling externally pumped concrete to enter the conveying pipe through the feed pipe, the column and the rotating frame.

[0006] As a further preferred embodiment of this utility model, a counterweight is fixedly connected to the top of the cantilever, a cable guide frame is fixedly connected to the top of the cantilever near the counterweight, and a first fixed frame and a second fixed frame are also fixedly connected to the top of the cantilever near the conveying pipe. A steel cable is fixedly connected between the counterweight, the cable guide frame, and the first fixed frame. The counterweight is used to improve the balance of the cantilever, and the steel cable between the counterweight, the cable guide frame, and the first fixed frame improves the suspension stability of the cantilever. A steel cable is fixedly connected between the second fixed frame and the material placing pipe to ensure the stability of the material placing pipe's suspended rotation.

[0007] As a further preferred embodiment of this utility model, the longitudinal section of the support beam is I-shaped, and multiple grooves are provided on both sides of the support beam to provide conditions for the installation and vertical sliding of the slider.

[0008] As a further preferred embodiment of this utility model, a pin is inserted into the positioning block, and one end of the fastening hook is provided with an installation hole. The fastening hook is rotatably connected to the pin located between the two corresponding positioning blocks through the installation hole and is fixed with screws. The rotatable fastening hook can be adjusted to the steel mesh frame used for floor slab pouring by flipping, thereby realizing the rapid fixing of the support beam, ensuring the stability of the entire material placement device and improving its ease of use.

[0009] As a further preferred embodiment of this utility model, a countersunk hole is provided in the center of the connecting block, and a fixing block is fixedly connected to the bottom of the adjusting bolt. The bottom of the connecting block is inserted into the countersunk hole through the fixing block, and the upper part of the adjusting bolt is inserted into the support beam. The adjusting bolt located above the support beam is also threaded with an adjusting nut. After one side of the slider extends through the corresponding groove to one side of the connecting block and is fixedly connected to the connecting block, the two side plates on the same side can be adjusted synchronously by adjusting the adjusting bolt, thereby cooperating with multiple positioning blocks to realize the lifting function of the fastening hook, so that after the fastening hook is flipped, it can be clamped and fixed to the steel mesh used for floor slab pouring in cooperation with the support beam.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the I-beam support beam and slider structure can flexibly adjust the height of the fastening hook to adapt to different working conditions. Thus, by using the rotatable fastening hook in conjunction with the adjusting bolt, it can be quickly clamped and fixed to the steel mesh of the floor slab, greatly simplifying the installation and transfer process, improving construction flexibility, and effectively solving the problem of cumbersome fixing of traditional equipment.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-5As shown, the present invention provides a concrete placement device for pouring concrete in buildings, including a column 1, a base 2 fixedly connected to the bottom of the column 1, the base 2 including a support platform 3, multiple support beams 4 fixedly connected to the outer circumference of the support platform 3, multiple side plates 5 movably connected to both sides of the support beams 4, multiple positioning blocks 6 fixedly connected to one side of the side plate 5, and fastening hooks 7 movably connected between two adjacent positioning blocks 6, multiple sliders 8 fixedly connected to the side of the side plate 5 away from the positioning blocks 6, connecting blocks 9 fixedly connected between the multiple sliders 8, adjusting bolts 10 movably connected inside the connecting blocks 9, a feed pipe 11 fixedly connected to the outer side of the column 1, a rotating frame 12 rotatably connected to the top of the column 1, a cantilever 13 fixedly connected to the outer side of the rotating frame 12, a conveying pipe 14 fixedly connected to the top of the rotating frame 12 and the top of the cantilever 13, and a placing pipe 16 rotatably connected to the end of the conveying pipe 14 away from the rotating frame 12 through a rotating joint 15.

[0015] like Figure 1 As shown, one end of the feed pipe 11 passes through the column 1 and extends to the top of the column 1, communicating with the inner cavity of the rotating frame 12. This allows externally pumped concrete to enter the conveying pipe 14 through the feed pipe 11, the column 1, and the rotating frame 12. A counterweight 17 is fixedly connected to the top of the cantilever 13. A cable guide frame 18 is fixedly connected to the top of the cantilever 13 near the counterweight 17. A first fixed frame 19 and a second fixed frame 20 are also fixedly connected to the top of the cantilever 13 near the conveying pipe 14. A steel cable is fixedly connected between the counterweight 17, the cable guide frame 18, and the first fixed frame 19. The counterweight 17 is used to improve the balance of the cantilever 13, and the steel cable between the counterweight 17, the cable guide frame 18, and the first fixed frame 19 improves the suspension stability of the cantilever 13. A steel cable is fixedly connected between the second fixed frame 20 and the placing pipe 16, which can ensure the stability of the placing pipe 16 during suspension rotation.

[0016] like Figures 2-5As shown, the longitudinal section of the support beam 4 is I-shaped. Multiple grooves 21 are provided on both sides of the support beam 4 to facilitate the installation and vertical sliding of the slider 8. A pin 22 is inserted into the positioning block 6. One end of the fastening hook 7 has a mounting hole 23, and the fastening hook 7 is rotatably connected to the pin 22 located between two corresponding positioning blocks 6 through the mounting hole 23 and fixed with screws. The rotatable and retractable fastening hook 7 can be adjusted by flipping onto the steel mesh frame used for floor slab pouring, thereby achieving rapid fixing of the support beam 4, ensuring the stability of the entire concrete placing device and improving its ease of use. A countersunk hole 24 is provided in the center of the connecting block 9. The bottom of the adjusting bolt 10 is fixedly connected to a fixing block 25. The bottom of the connecting block 9 is inserted into the countersunk hole 24 through the fixing block 25. The upper part of the adjusting bolt 10 is inserted into the support beam 4. The adjusting bolt 10 located above the support beam 4 is also threadedly connected to an adjusting nut 26. One side of the slider 8 extends through the corresponding groove 21 to the side of the connecting block 9 and is fixedly connected to the connecting block 9. The two side plates 5 on the same side can be adjusted synchronously by adjusting the adjusting bolt 10, thereby cooperating with multiple positioning blocks 6 to realize the lifting function of the fastening hook 7, so that after the fastening hook 7 is flipped, it can cooperate with the support beam 4 to clamp and fix it to the steel mesh used for floor slab pouring.

[0017] It should be noted that this utility model is a concrete placement device for building concrete pouring. In use, the support platform 3 of the base 2 is placed in the construction area, and multiple fastening hooks 7 are rotated around the pin 22 at one end, so that the other end of the fastening hook 7 is rotated 90 degrees and placed below the steel mesh. Then, the adjusting nut 26 on the adjusting bolt 10 is rotated, so that the adjusting nut 26 rotates on the adjusting bolt 10 and lifts the adjusting bolt 10, which drives the connecting block 9 and the slider 8 connected to the connecting block 9 to move vertically along the slide groove 21 of the support beam 4. The slider 8 simultaneously drives the side plate 5 and the positioning block 6 on the side plate 5 to move upward until the fastening hooks 7 between the positioning blocks 6 cooperate with the support beam 4 to clamp the bottom of the steel mesh, so that the fastening hooks 7 hook the steel mesh and complete the device fixation. There is no need to open holes in the reference surface. After fixing, connect the external concrete pumping equipment to the feed pipe 11. The pumping equipment delivers concrete to the feed pipe 11, and the concrete enters the internal channel of the column 1 through the feed pipe 11, and then enters the inner cavity of the rotating frame 12 from the top of the column 1. The rotating frame 12 can rotate around the top of the column 1. When rotating, it drives the outer cantilever 13 to rotate synchronously. The conveying pipe 14 at the top of the cantilever 13 moves with the cantilever 13. Concrete flows from the inner cavity of the rotating frame 12 into the conveying pipe 14, and then along the conveying pipe 14 to the rotary joint 15, and then into the placing pipe 16. According to the pouring requirements, the operator can adjust the angle of the placing pipe 16 through the rotary joint 15, and at the same time rotate the rotating frame 12 to change the position of the cantilever 13 and the conveying pipe 14 to achieve material placement in different areas.
