Description

Technical Field

[0001] This application relates to the field of slipform construction technology, and in particular to a slipform structure for slope-fitted concrete. Background Technology

[0002] Slope concrete slipform structure utilizes a formwork that moves along the slope (i.e., "slipform"). After the concrete is laid, the formwork is pulled up by traction equipment. During the movement, the concrete is continuously squeezed, vibrated and shaped, thus forming a complete, flat and dense concrete slope. Slipform construction technology is widely used in concrete slope construction because it can operate continuously and form in one go.

[0003] The existing Chinese utility model patent with publication number CN215593593U discloses an automatic vibration and smoothing concrete ramp slipform device; however, it still has the following shortcomings in practical use: This patented method involves adding a vibration device fixed to the top of the formwork, indirectly transferring vibration energy to the concrete by vibrating the formwork. However, this indirect vibration method suffers from high energy loss, has limited effectiveness in vibrating deeper layers of concrete, and its fixed vibration range can easily create blind spots between the vibrators, leading to uneven concrete density and affecting overall strength. Utility Model Content

[0004] To improve the problem of poor concrete vibration effect, this application provides a slope-fitting concrete slipform structure.

[0005] This application provides a slope-supported concrete slipform structure using the following technical solution: A slipform structure for slope-fitting concrete includes a supporting shell and two sets of wheels rotatably mounted on the supporting shell. A screed is fixedly mounted on the supporting shell. A vibrator is installed inside the supporting shell to directly apply vibration energy to the interior of the concrete. A moving plate is fixedly mounted on the vibrator to move the vibrator and expand the vibration range. A moving component is installed on the wheels to control the expanding and merging movement of the moving plate.

[0006] By adopting the above technical solution, the supporting shell serves as the basic load-bearing component of the entire structure. The wheels at its bottom allow the device to roll along the slope. The fixed trowel is responsible for finally smoothing the concrete surface. The vibrator is connected to the moving assembly via a moving plate. The moving assembly starts working under the drive of the wheels, controlling the moving plate fixed to the vibrator to perform periodic merging and expanding movements. Furthermore, the vibrator's vibrating rod is inserted into the concrete, thereby directly applying the vibration energy to the interior of the concrete and expanding the vibration range, thus improving the concrete vibration effect.

[0007] Preferably, the moving component includes two axles that are fixed coaxially with the wheels, and two rotating shafts are rotatably arranged through the support housing. Synchronous pulleys are fixed coaxially at the ends of the axles and rotating shafts away from the wheels. Synchronous belts are driven on the two synchronous pulleys. The moving plate is moved by the rotating shafts through a limiting structure.

[0008] By adopting the above technical solution, the moving component transmits power to the rotating shaft via the wheel-driven axle, synchronous pulley, and synchronous belt, and then converts the rotational motion into the mechanical motion of the moving plate through the limiting structure on the rotating shaft.

[0009] Preferably, the limiting structure includes a circular plate fixedly disposed with the rotating shaft, a sliding column fixedly disposed on the circular plate, a first limiting groove symmetrically opened on the supporting shell, a first limiting post slidably disposed in the first limiting groove, and a circular ring plate slidably disposed on the first limiting post and slidably disposed with the sliding post. The circular ring plate realizes the expansion and merging movement of the vibrator through a control structure.

[0010] By adopting the above technical solution, the limiting structure uses a circular plate that rotates synchronously with the rotating shaft to drive the sliding column on it. The sliding column slides in the circular ring plate, forcing the circular ring plate to make stable left and right linear movements in the first limiting groove through the first limiting columns on both sides, thereby transmitting the rotational power to the control structure to drive the vibrator.

[0011] Preferably, the control structure includes a slide plate fixedly disposed with the annular plate, five second limiting grooves are provided on the slide plate, a second limiting post fixedly connected to the moving plate is slidably disposed in the second limiting groove, two support posts are fixedly disposed on the support housing and slidably disposed through the moving plate, an extension plate fixedly disposed on the moving plate and fixed to the vibrating end of the vibrator, and protective shells are symmetrically fixedly disposed on the support housing.

[0012] By adopting the above technical solution, the control structure transmits the linear motion of the circular plate to the slide plate. The special second limiting groove on the slide plate cooperates with the second limiting post fixed on the moving plate. Under the guidance of the support post, the left and right movement of the slide plate is transformed into the merging and expansion movement of five moving plates. Finally, the extension plate drives the vibrator to complete the compound vibration action. The entire transmission mechanism is protected by a protective shell.

[0013] Preferably, the extension direction of the first limiting groove is parallel to the length direction of the slide plate, and the extension direction of the annular plate is perpendicular to the length direction of the first limiting groove.

[0014] By adopting the above technical solution, the extension direction of the first limiting groove is parallel to the length direction of the slide plate and perpendicular to the extension direction of the circular plate. This layout ensures that the force direction of the circular plate is consistent with the guiding direction of the first limiting groove, thereby efficiently and accurately converting the circular motion of the slide column into the horizontal linear reciprocating motion of the slide plate.

[0015] Preferably, the five second limiting grooves are arranged radially.

[0016] By adopting the above technical solution, the five second limiting grooves are arranged in a radial pattern. This radial pattern is the core of motion conversion. It can accurately decompose the single horizontal straight line input of the skateboard into a compound motion of five moving boards switching between merging and expanding states.

[0017] Preferably, the sliding column is located at the eccentric position of the circular plate.

[0018] By adopting the above technical solution, the sliding column is set at the eccentric position of the circular plate to drive the circular ring plate to move when the circular plate rotates.

[0019] Preferably, the timing pulley, timing belt, annular plate, and first limiting post are all disposed inside the protective shell.

[0020] By adopting the above technical solution, the synchronous pulley, synchronous belt, circular plate, and first limiting post are all set inside the protective shell. This can effectively reduce the intrusion of concrete slurry into these precision transmission components, ensure the reliability of power transmission, and extend the service life of the entire device.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By creating a second limiting groove on the slide plate where five extended lines converge at a single point, with the five second limiting grooves being vertical in the middle and inclined on both sides, the slide plate moves synchronously, causing the vibrator to expand from the middle to both sides. The vibrating end of the vibrator continuously merges and expands inside the concrete, dynamically covering a larger area and eliminating the blind spots between fixed vibrators. This expansion and merging motion generates strong shear force and disturbance effect inside the concrete, promoting slurry flow and allowing internal air bubbles to be quickly discharged along a better path. Moreover, the vibration energy acts directly on the inside of the concrete, rather than being indirectly transmitted through the vibrating template, resulting in minimal energy loss and extremely high vibration efficiency. This is crucial for ensuring the density of the sloping concrete and preventing surface air bubble defects later on.

[0022] 2. The trowel is positioned behind the slide plate. When the slide plate moves, it contacts the concrete being laid before the trowel. The reciprocating motion of the slide plate can pre-push and rough-level the concrete, breaking the initial internal friction of the concrete accumulation. This allows the trowel behind it to only perform fine leveling, resulting in less working resistance and making it easier to achieve a higher surface flatness, while also reducing the wear on the trowel.

[0025] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0026] This application discloses a slope-supported concrete slipform structure.

[0027] Reference Figure 1 , Figure 2 A sliding formwork structure for slope-fitting concrete includes a supporting shell 1 and two sets of wheels 3 rotatably mounted on the supporting shell 1. The inner walls of the supporting shell 1 are fixed to the two sides of the troweling plate 2. Five vibrators 5 are installed inside the supporting shell 1. The vibrators 5 are used to directly apply vibration energy to the interior of the concrete. The mounting ends of the five vibrators 5 are respectively fixed to the upper surfaces of five movable plates 6. The movable plates 6 are used to drive the vibrators 5 to move and expand the vibration range. The wheels 3 are equipped with moving components 4, which are used to control the moving plates 6 to expand and merge.

[0028] In use, the entire slipform structure is pulled by a traction device via a traction cable and moves up the concrete slope. At this time, the support shell 1, as an integral frame, has two wheels 3 at its bottom that begin to roll along the slope, converting the linear traction force into rotational power. The trowel 2, fixed to the rear of the support shell 1, follows closely behind, performing final smoothing and finishing on the pre-treated concrete slope. At the same time, the moving component 4, driven by the wheels 3, begins to work, controlling the moving plate 6, which is fixed to the vibrator 5, to perform periodic merging and expanding movements. This allows the vibrator 5's vibrating rod to not only penetrate deep into the concrete but also expand the vibration range during movement, achieving efficient internal compaction.

[0029] Reference Figure 3 , Figure 4 The moving component 4 includes two axles 41 that are coaxially fixed to the wheels 3. The axles 41 pass through the interior of the support housing 1 and are rotatably connected to the support housing 1. Both sides of the support housing 1 are rotatably connected to a rotating shaft 42. The outer walls of the axles 41 and the rotating shafts 42 are coaxially fixed to the synchronous wheels 43. The synchronous wheels 43 are located at the ends of the axles 41 and the rotating shafts 42 away from the wheels 3. The outer walls of the two synchronous wheels 43 mesh with the two ends of the synchronous belt 44. The rotating shafts 42 realize the movement of the moving plate 6 through a limiting structure.

[0030] When wheel 3 rolls, it drives the coaxially fixed wheel axle 41 to rotate synchronously. The synchronous wheel 43 at the end of wheel axle 41 transmits power to another synchronous wheel 43 at the end of shaft 42 through synchronous belt 44, thereby driving shaft 42 to rotate within the support housing 1. This synchronous transmission system ensures that for every distance the sliding mold moves upward, shaft 42 rotates by a corresponding angle according to a fixed transmission ratio, providing a stable and continuous power input for subsequent mechanisms. The rotational motion of shaft 42 is then received by the limiting structure connected to it and begins to drive the moving plate 6 to move.

[0031] Reference Figure 4 , Figure 5 The limiting structure includes a circular plate 45 fixedly disposed with the rotating shaft 42. The circular plate 45 is coaxially fixed with the rotating shaft 42. The circular plate 45 is disposed at the end of the rotating shaft 42 away from the wheel 3. The end of the circular plate 45 away from the rotating shaft 42 is fixedly disposed with a sliding column 47. The support housing 1 is symmetrically provided with a first limiting groove 48. The inner wall of the first limiting groove 48 slides with the outer wall of the first limiting column 49. The inner side of the first limiting column 49 is fixed with the surface of the annular plate 46. The inner side of the annular plate 46 slides with the outer wall of the sliding column 47. The annular plate 46 realizes the expansion and merging movement of the vibrator 5 through the control structure. The sliding column 47 is disposed at the eccentric position of the circular plate 45 and is used to drive the movement of the annular plate 46.

[0032] The rotation of the shaft 42 drives the circular plate 45 fixed on it to rotate together. Since the sliding column 47 is fixed at the eccentric part of the circular plate 45, it will make a circular motion when rotating. The sliding column 47 is also slidably set inside the annular plate 46, thereby generating a periodic lateral thrust on the annular plate 46. The two sides of the annular plate 46 are slidably connected to the first limiting groove 48 on the support housing 1 through the first limiting column 49. The first limiting groove 48 restricts the movement trajectory of the first limiting column 49 and the annular plate 46, making them unable to rotate and only able to make strict left and right reciprocating linear motion. In this way, the continuous rotation of the shaft 42 is converted into the stable left and right linear motion of the annular plate 46. The annular plate 46 then transmits this motion to the control structure set with it, and finally drives the vibrator 5 to realize the expansion and merging vibration action.

[0033] Reference Figure 3 , Figure 4 The control structure includes a sliding plate 410 fixedly mounted to the annular plate 46. The sliding plate 410 has five second limiting grooves 412 arranged radially. The second limiting groove 412 in the middle position is vertical, while the four second limiting grooves on either side of the middle are symmetrically inclined. The central extension lines of the five second limiting grooves 412 converge at a single point. The inner wall of each second limiting groove 412 slides against the outer wall of a second limiting post 413. The top of the second limiting post 413 is fixed to the bottom of the moving plate 6. The inner side of the support housing 1 is fixed to both ends of the two support posts 411. Both support columns 411 penetrate the interior of the movable plate 6 and are slidably disposed with the movable plate 6. The outer wall of each movable plate 6 is fixed to the surface of an extension plate 415. The inner wall of the extension plate 415 is fixedly installed with the vibrating end of the vibrator 5. Both sides of the inner wall of the support housing 1 are fixed to the surface of a protective shell 414. The extension direction of the first limiting groove 48 is parallel to the length direction of the slide plate 410. The extension direction of the ring plate 46 is perpendicular to the length direction of the first limiting groove 48. The synchronous pulley 43, the synchronous belt 44, the ring plate 46 and the first limiting column 49 are all disposed inside the protective shell 414.

[0034] The left and right linear motion of the ring plate 46 is directly transmitted to the slide plate 410 fixedly connected to it. When the slide plate 410 moves left and right, the groove wall of the second limiting groove 412 will force the second limiting post 413 in it to move along a specific path. The moving plate 6 located in the middle vertical groove basically makes a linear motion. Each left and right reciprocating motion of the slide plate 410 drives the five moving plates 6 to complete a cycle from merging to expansion and back to merging. The moving plates 6 drive the vibrating end of the vibrator 5 through the extension plate 415, so that it performs a compound motion with the same trajectory inside the concrete, which optimizes the vibration effect. In addition, all precision transmission components such as the synchronous pulley 43, synchronous belt 44, and ring plate 46 are sealed inside the protective shell 414 to ensure the reliability of the long-term operation of the equipment. The bottom of the second limiting groove 412 does not penetrate the slide plate 410, which is used to prevent concrete from entering the interior of the second limiting groove 412 when the slide plate 410 is pre-flattened. The area of ​​the moving plate 6 can completely cover the second limiting groove 412 to avoid the movement of the moving plate 6 getting stuck.

[0035] Among them, the vibrator 5 is existing technology, and its structural principle will not be described in detail. The vibrator 5 is preferably a high-frequency insertion electric vibrator 5 (also known as a vibrating rod), which is connected to the on-board generator through a cable.

[0036] The implementation principle of the slipform structure for sloping concrete in this application embodiment is as follows: During use, the entire slipform structure is pulled up the concrete slope by a traction device via wire. At this time, the support shell 1, as the overall frame, has two wheels 3 at its bottom and the rear wheel rolling along the slope, converting the linear traction force into rotational power. The trowel 2, fixed to the rear of the support shell 1, follows closely behind, performing final smoothing and finishing on the pre-treated concrete slope. At the same time, the moving component 4 starts working under the drive of the wheels 3. The vibrator 5 is connected to the moving component 4 through the moving plate 6, thereby directly applying the vibration energy to the inside of the concrete and expanding the vibration range, thus improving the concrete vibration effect.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
