Description

Technical Field

[0001] The invention belongs to the technical field of construction equipment, and in particular relates to a well-shaped beam casting device. Background Art

[0002] A well-shaped beam is a beam that intersects horizontally and vertically without distinguishing between primary and secondary beams, forming a well shape. The well-shaped beam is widely used in various buildings due to its reasonable stress-bearing characteristics and unique structural layout.

[0003] At present, the production and pouring process of the cross-beam generally prioritizes weaving and erecting the steel cage, and cross-placing it according to the cross shape to be poured, then using prefabricated formwork as a fence to surround and fix the steel cage, and then pouring concrete into the fence for pouring. However, due to the limitations of the steel cage and the viscosity of the concrete, manual pouring can only pour concrete from the top of the steel cage, and cannot pour concrete from the inside of the steel cage. The concrete also needs to slowly seep from the top of the steel cage to the bottom. Sometimes the pouring speed is too fast, which will cause the concrete to overflow. Therefore, the pouring process is time-consuming and labor-intensive, and the workers have to bend over for a long time, resulting in high labor intensity. At the same time, it reduces the production and pouring efficiency of the cross-beam to a certain extent. Summary of the Invention

[0011] Preferably, a plurality of rollers are installed on the inner wall of the U-shaped block near the upper end.

[0012] Preferably, a square groove is provided on the lower surface of the U-shaped block, and a plurality of fixed shafts are fixedly connected inside the square groove. The arc surface of the fixed shaft is slidably connected to a sliding block, and the sliding block can slide left and right along the axial position of the fixed shaft in the square groove. The arc surface of the fixed shaft is covered with a spring, and the two ends of the spring are respectively fixedly connected to the sliding block and the inner wall of the square groove. The lower surface of the sliding block is fixedly connected to a motor, and the output end of the motor is fixedly connected to a driving wheel.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention adopts the setting of the pouring structure. When pouring the cross beam, it is only necessary to insert the pouring piece at one end into the gap in the steel cage. The upper part is connected to the flange by a concrete pipe to transport concrete. The concrete is sent into the horizontal axis through the conveying shaft and enters the pouring piece on the surface of the rotating ring through the discharge port. Since the discharge port is only set near the lower end, it effectively avoids the two pouring pieces rotating to the upper end from overflowing concrete and causing waste. Therefore, the concrete can be poured inside the steel cage, and the whole device can be pushed to the space surrounded by the enclosure. The pouring unit moves upward as a whole. When one of the pouring parts is blocked by the steel cage, the reaction force will drive the rotating ring to rotate, and then the blocked pouring part will be rotated backward. The rotated pouring part will be out of the discharge port position and will be blocked and no longer discharged. In this process, the pouring part in the front will move down and be inserted into the steel cage, thereby realizing a cyclic rotation. The entire device can complete the internal concrete pouring while moving. There is no need for manual pouring. At the same time, concrete enters from the inside of the steel cage, making the concrete filling faster, thereby effectively reducing the labor of workers.

[0017] 2. The present invention sets a positioning structure, and the U-shaped blocks on both sides of the lower end can be used to clamp the upper end of the enclosure formed by the prefabricated template to limit the entire device. At the same time, rollers are installed in the U-shaped blocks to reduce friction during rolling. The distance between the two U-shaped blocks can be adjusted by turning the handle to rotate the threaded rod A to drive the two movable plates to move relative to each other. In addition, the driving wheel driven by the motor at the bottom is pressed against the side wall of the enclosure during this process, and the driving wheel is driven to rotate by the motor, so that the entire device can be automatically moved on the enclosure. By setting the motor output power to achieve different operating speeds, it is adjusted according to the amount of concrete poured to ensure that the movement of the entire device is directly above the prefabricated template, making the pouring process more stable and easy to control.

[0018] 3. The present invention provides a scraping piece so that the concrete can be leveled while being poured and moved synchronously. The two anti-overflow plates can be moved relative to each other by rotating the threaded rod B. The two plates can be adjusted according to the width of the enclosure, effectively preventing concrete from overflowing from both sides of the anti-overflow plates during leveling, thereby further reducing the time workers spend on manual leveling.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, an embodiment of the present invention provides a cross-beam casting device, including a mounting plate 1, a handrail 11 is fixedly connected to the upper surface of the mounting plate 1, a casting structure 2 for mobile casting in a steel cage is installed on the surface of the mounting plate 1, and the casting structure 2 includes a fixed flange 21, the fixed flange 21 is fixedly connected to the mounting plate 1, and a circular hole is opened in the middle for concrete to pass through, the lower end of the fixed flange 21 is fixedly connected to a conveying shaft 22, and the lower end of the conveying shaft 22 is fixedly connected to a horizontal shaft 23, and two discharge ports 231 are provided at the lower end of the arc surface of the horizontal shaft 23, and the two discharge ports 231 are symmetrical along the axial position of the conveying shaft 22. The arc surface of the horizontal shaft 23 corresponding to the two discharge ports 231 are rotatably connected to a rotating ring 232, and the arc surface of the rotating ring 232 is evenly spaced and fixedly connected with three casting parts 233, and the casting parts 233 are hollow inside and connected to the rotating ring 232.

[0029] The working principle and beneficial effects of the above technical solution are as follows: through the setting of the casting structure 2, when casting the cross beam, it is only necessary to insert the casting piece 233 at one end into the gap in the steel cage, and the concrete is transported by the concrete pipe at the upper part, and is sent into the horizontal shaft 23 through the conveying shaft 22, and enters the casting piece 233 on the surface of the rotating ring 232 through the discharge port 231, so that the concrete can be poured inside the steel cage. The entire device can be pushed. When one of the casting pieces 233 is blocked, the rotating ring 232 will be driven to rotate due to the reaction force, and the blocked casting piece 233 will be rotated backward. During this process, the casting piece 233 at the upper end will move down and be inserted into the steel cage, thereby realizing smooth internal concrete pouring during movement, effectively reducing the labor of workers.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the lower end of the casting part 233 is arc-shaped.

[0031] The working principle and beneficial effects of the above technical solution are: by setting the arc-shaped lower end, it is avoided that the overly sharp lower end is stuck with the steel cage, which is not conducive to movement.

[0032] In addition, the upper end of the fixed flange 21 is rotatably connected to the connecting flange 24 , the lower surface of the connecting flange 24 is fixedly connected to an L-shaped block 241 , and the upper end of the L-shaped block 241 is fixedly connected to an arc-shaped limiting member 242 .

[0033] The working principle and beneficial effects of the above technical solution are as follows: by setting the rotatable connecting flange 24, the concrete pipe can be freely rotated during movement to avoid entanglement. At the same time, the arc-shaped limiter 242 on the L-shaped block 241 is used to limit the concrete pipe to avoid bending the concrete pipe at the connection point, thereby affecting the output of concrete.

[0034] The arc-shaped limiting member 242 is a rubber member with an arc-shaped surface.

[0035] The working principle and beneficial effects of the above technical solution are as follows: the arc-shaped limiter 242 made of rubber can provide buffering, and after the surface is arc-treated, it can effectively avoid scratching the concrete pipe when in contact with the concrete pipe.

[0036] like Figure 5 , Figure 6As shown, in this embodiment, a positioning structure 3 is provided on the surface of the mounting plate 1 between the fixed flange 21 and the armrest 11. The positioning structure 3 includes a slide groove 31 opened on the surface of the mounting plate 1. The inner wall of the slide groove 31 is slidably connected to a slider 32. The upper end of the slider 32 is fixedly connected to a movable plate 33. The upper surface of the mounting plate 1 is fixedly connected to a fixed plate 331 near the center position of the slide groove 31. The internal rotation of the fixed plate 331 is connected to a threaded rod A332. The threaded rod A332 is a bidirectional threaded rod. The two ends of the threaded rod A332 are respectively inserted into the movable plates 33 on both sides and are threadedly connected to the movable plates 33. The lower surface of the slider 32 is fixedly connected to a connecting piece 34. The lower surface of the connecting piece 34 is fixedly connected to a U-shaped block 35.

[0037] The working principle and beneficial effects of the above technical solution are as follows: through the setting of the positioning structure 3, the U-shaped blocks 35 on both sides of the lower end can be used to clamp the upper end of the enclosure formed by the prefabricated template to limit the entire device. The distance between the two U-shaped blocks 35 can be adjusted by rotating the handle 333 to rotate the threaded rod A332 to drive the two movable plates 33 to move relative to each other, thereby ensuring that the movement of the entire device is directly above the prefabricated template, making the casting process more stable and easy to control.

[0038] Among them, stabilizing rods 334 are fixedly connected to both sides of the fixed plate 331 near the threaded rod A332. Both ends of the stabilizing rod 334 pass through the movable plate 33. Both ends of the stabilizing rod 334 are fixedly connected to discs.

[0039] The working principle and beneficial effects of the above technical solution are as follows: by disposing the stabilizing rods 334 on both sides, the two movable plates 33 are stabilized and limited, making the adjustment more stable.

[0040] At the same time, a plurality of rollers 351 are installed on the inner wall of the U-shaped block 35 near the upper end.

[0041] The working principle and beneficial effects of the above technical solution are as follows: through the arrangement of a number of rollers 351, when the U-shaped block 35 clamps the upper end of the enclosure, the rollers 351 abut against the enclosure, changing the sliding friction when the U-shaped block 35 moves into rolling friction, making the entire device easier to push.

[0042] In addition, a square groove is provided on the lower surface of the U-shaped block 35, and a number of fixed shafts 352 are fixedly connected inside the square groove. The arc surface of the fixed shaft 352 is slidably connected to a sliding block 353, and the sliding block 353 can slide left and right along the axial position of the fixed shaft 352 in the square groove. The arc surface of the fixed shaft 352 is covered with a spring, and the two ends of the spring are respectively fixedly connected to the sliding block 353 and the inner wall of the square groove. The lower surface of the sliding block 353 is fixedly connected to the motor 354, and the output end of the motor 354 is fixedly connected to the driving wheel 355.

[0043] The working principle and beneficial effects of the above technical solution are as follows: through the setting of the lower end structure of the U-shaped block 35, when the U-shaped block 35 is stuck in the upper position of the enclosure, the driving wheel 355 at the lower end abuts against the side wall of the enclosure. As the U-shaped block 35 continues to move relative to each other, the driving wheel 355 is compressed, thereby causing the sliding block 353 to slide relatively on the fixed shaft 352 and compressing the spring. The spring is used to buffer the motor 354 and the driving wheel 355, and to keep the two against the side wall of the enclosure at all times, so that the driving wheel 355 can rotate under the drive of the motor 354, thereby driving the entire device to move automatically.

[0044] like Figure 7 As shown, in this embodiment, a leveling structure 4 is provided on one side of the lower surface of the mounting plate 1 near the connecting member 34. The leveling structure 4 includes a support block 41. The upper surface of the support block 41 is fixedly connected to the mounting plate 1. The lower surface of the support block 41 is fixedly connected to a scraping member 42. The scraping member 42 is triangular in shape and hollowed out at the bottom. The scraping member 42 is placed parallel to the U-shaped block 35.

[0045] The working principle and beneficial effects of the above technical solution are as follows: by setting the scraping member 42, while pouring and moving synchronously, the scraping member 42 scrapes the surface of the poured concrete flat, thereby further reducing the time for workers to manually scrape.

[0046] The internal thread of the scraping member 42 is connected to a threaded rod B43, which is a bidirectional threaded rod. Both ends of the threaded rod B43 are fixedly connected to a rotating block 44, and the arc surface of the threaded rod B43 is threadedly connected to two anti-overflow plates 45.

[0047] The working principle and beneficial effects of the above technical solution are as follows: by setting the anti-overflow plate 45 with adjustable relative position, the distance between the two anti-overflow plates 45 can be adjusted according to the casting width of the cross-beam surrounded by the enclosure, thereby blocking the concrete overflowing to both sides and avoiding the overflow of concrete.

[0048] Working principle and usage process:

[0049] When pouring the well beam, first place the entire device above the precast panel enclosure, put the steel cage inside the precast panel enclosure, and insert the casting piece 233 near the lower end into the steel cage. By turning the handle 333, the movable plate 33 is driven to move relatively, thereby moving the U-shaped block 35 at the lower end toward the relative position, and making the inner wall of the U-shaped block 35 fit into the upper position of the enclosure. At this time, the roller 351 abuts against the upper end of the enclosure, and the driving wheel 355 at the lower end abuts against the side wall of the enclosure at the same time. Then, the concrete delivery pipe is connected to the surface of the connecting flange 24, and the concrete delivery pipe is limited by a number of arc-shaped limit members 242. Then, mixing can be carried out. The concrete is output, and the motor 354 is turned on to rotate the driving wheel 355. The concrete passes through the connecting flange 24, the fixing flange 21, the conveying shaft 22, and the horizontal shaft 23 in sequence, and is discharged through the discharge port 231 opened at the lower end of the horizontal shaft 23. The concrete falling from the discharge port 231 is poured into the steel cage from the inside through the casting piece 233. At the same time, since the entire device is continuously moved forward driven by the driving wheel 355, several casting pieces 233 are changed in position due to the rotation of the rotating ring 232, thereby realizing mobile casting. At the same time, the leveling piece 42 located at the rear side continuously levels the surface concrete after pouring and prevents the concrete from overflowing.
