Description

Technical Field

[0001] This application relates to the field of construction, and more particularly to a molding device for testing the slump of concrete during on-site pouring. Background Technology

[0002] Slump refers to the workability of concrete, specifically ensuring smooth construction. It includes the concrete's water retention, fluidity, and cohesiveness. Workability refers to the ease of construction and uniform compaction of concrete; it's a comprehensive property encompassing fluidity, cohesiveness, and water retention. The slump of concrete should be determined based on factors such as the building's structural cross-section, reinforcement content, transport distance, pouring method, transportation mode, vibration capacity, and climate. These factors should be considered comprehensively when selecting the mix proportion, and a lower slump is preferable. After concrete preparation, a slump test cylinder is typically used to test the slump performance of the concrete to determine if it meets standards.

[0003] Existing concrete slump testing devices typically work by activating two electric actuators, which in turn move two fixed plates and a slump cylinder vertically downwards, ensuring the bottom of the slump cylinder is in close contact with the top of the platform. Concrete is then poured from the hopper into the storage box, and a slide block is slid along a sliding rod to the appropriate position. Holding the vertical rod, a pressure plate is inserted into the slump cylinder, and the concrete is manually compacted. This process is repeated until the slump cylinder is completely filled. The two electric actuators are then activated to reset the device, and the two telescopic rods move the two fixed plates and the slump cylinder vertically upwards, raising the slump cylinder to the appropriate height and exposing all the compacted concrete. The height of the concrete after slump is measured, and the difference between the height of the slump cylinder and the height of the concrete after slump is the slump, thus completing the concrete slump testing.

[0004] However, the above solution has the following problems in use: When in use, the slump cone is set up as an integral unit, and vibration is required to separate the concrete and the component during operation. At the same time, the slump cone is exposed to the external environment when observing slump, which can affect the measurement efficiency. Furthermore, it is not convenient to quickly and evenly distribute the concrete inside the slump cone during use. Utility Model Content

[0005] One of the purposes of this application is to provide a slump testing device for concrete pouring sites, which aims to solve the problem of low separation efficiency of existing concrete slump testing devices.

[0006] The technical solution of this application is: A concrete pouring site slump testing and forming device includes a support frame, multiple first actuators, a second actuator, a top cover, two side covers that can be opened and closed, and a compaction mechanism. The top cover is movably disposed within the inner cavity of the support frame and has an opening at its top. One end of each of the multiple first actuators is connected at intervals to the inner side of the top plate of the support frame, and the other end is driven at intervals to the top cover, for driving the top cover to rise and fall. The two side covers are hinged to the outer periphery of the lower part of the top cover and are used to form a truncated cone-shaped slump cylinder together with the top cover and the bottom plate of the support frame to collect the concrete injected through the opening. The compaction mechanism is movably disposed within the inner cavity of the slump cylinder and is used to compact and flatten the concrete. One end of each second actuator is connected to the inner side of the top plate of the support frame, and the other end passes through the opening and is driven to the compaction mechanism, for driving the compaction mechanism to rise and fall.

[0007] As one technical solution of this application, the first driver includes a telescopic rod.

[0008] As one technical solution of this application, the second driver includes a telescopic rod.

[0009] As one technical solution of this application, a rotatable annular worm gear is provided in the inner cavity of the top cover. A shaft is fixedly installed on the outer side of the top cover, and the shaft is located inside the worm wheel. A side cover plate is rotatably connected to the end of the shaft. A pull rope is connected to the inner side of the top plate of the support frame. The bottom end of the pull rope passes through the inner cavity of the top cover and is wound around the upper part of the annular worm gear to drive the annular worm gear to rotate. Worm wheels are fixedly connected to the top of the two side cover plates, and shafts are rotatably connected inside the worm wheels. These shafts extend into the inner cavity of the top cover and mesh with the opposite outer sides of the annular worm gear, so that when the annular worm gear rotates, it drives the two worm wheels to rotate and drives the two side cover plates to open or close the slump cylinder. A torsion spring is connected between the annular worm gear and the top cover.

[0010] As a technical solution of this application, each of the side cover plates has a groove and two spaced-apart viewing windows on its outer wall. The groove is located between the two viewing windows. The shaft of the worm gear is driven to a screw through a bevel gear connector. The screw is rotatably disposed in the groove, and a cleaning plate is driven to the screw. The cleaning plate is movably disposed on the outer surface of the two viewing windows for cleaning the viewing windows.

[0011] As one technical solution of this application, a slider is threaded onto the screw; the cleaning plate is fixed on the slider, and the range of movement of the cleaning plate is greater than the area of ​​the two viewing windows.

[0012] As one technical solution of this application, the compaction mechanism includes a pressure plate, and the other end of the second driver is connected to the top of the pressure plate.

[0013] The beneficial effects of this application are: By setting a split top cover and two side covers that can be opened and closed, it allows for rapid lateral separation of concrete from the slump cone after concrete is filled into it during use. This effectively improves the separation efficiency between the slump cone and the concrete, and also allows for isolated slump observation inside the slump cone. This effectively reduces the influence of the external environment, speeds up the measurement process, and enables rapid and uniform distribution of concrete inside the slump cone.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Example: Please refer to Figure 1 (Refer to) Figures 2 to 6 To address the problem that existing concrete pouring site slump testing molding modules are inconvenient for separating the concrete holding components during operation, this application provides a concrete pouring site slump testing molding device, which mainly includes a support frame 2, multiple first actuators 3, second actuators 14, a top cover 4, two side covers 5 that can be opened and closed, and a compaction mechanism; wherein, the top cover 4 is vertically and vertically disposed in the inner cavity of the support frame 2, and has an opening 1 at the top; at the same time, one end of each of the multiple first actuators 3 is respectively and spaced apart to be connected to the inner side of the top plate of the support frame 2, and the other end is connected to the other end of the first actuator 14. The two end caps are respectively and intermittently connected to the top cover 4 to drive the top cover 4 to rise and fall; and the two side cover plates 5 are respectively hinged to the bottom of the top cover 4 and are used to form a truncated cone-shaped slump cylinder together with the top cover 4 and the bottom plate of the support frame 2 to hold the concrete injected through the opening 1; in addition, the compaction mechanism is vertically and vertically arranged in the inner cavity of the truncated cone-shaped slump cylinder to compact and flatten the concrete; one end of the second driver 14 is connected to the inner side of the top plate of the support frame 2, and the other end passes through the opening 1 and is connected to the compaction mechanism to drive the compaction mechanism to rise and fall.

[0025] After the two side covers 5 are closed, they together with the top cover 4 and the bottom of the support frame 2 form a closed truncated cone-shaped slump cylinder. Therefore, when the device is in use, by designing a split top cover 4 and side covers 5, the first driver 3 drives the top cover 4 to move down. When the top cover 4 moves down, its outer side covers 5 will close together and then abut against the bottom plate of the support frame 2, thus forming a concrete storage space. The viewing window 7 on the side covers 5 allows the staff to observe the process from the outside. After the concrete is filled into the slump cylinder, it can quickly separate the concrete from the slump cylinder of the receiving component, thereby improving the separation efficiency between the slump cylinder and the concrete. At the same time, it can also perform isolated slump observation inside the slump cylinder, reduce the influence of the external environment, speed up its measurement efficiency, and can perform rapid and uniform distribution of the concrete inside the slump cylinder.

[0026] It should be noted that in this embodiment, both the first driver 3 and the second driver 14 can be telescopic rods in the prior art, and their specific structures and working principles will not be described in detail here; specifically, two first drivers 3 can be used, one second driver 14 can be used, and the second driver 14 is located between the two first drivers 3.

[0027] Furthermore, a shaft is fixedly installed on the outer side of the top cover 4, and the shaft is located inside the worm gear 10. The end of the shaft is rotatably connected to a side cover plate 5. A pull rope 6 is connected to the inner side of the top plate of the support frame 2. The bottom end of the pull rope 6 passes into the inner cavity of the top cover 4 and is wound around the upper part of the annular worm gear 8 to drive the annular worm gear 8 to rotate. The tops of the two side cover plates 5 are fixedly connected to the worm gear 10, and the worm gear 10 is rotatably connected to the inside of the worm gear 10, and extends into the inner cavity of the top cover 4 and is connected to the annular worm gear 8. The two outer sides of the annular worm 8 mesh with each other so that when the annular worm 8 rotates, it drives the two worm wheels 10 to rotate and drives the two side cover plates 5 to open or close the truncated cone-shaped collapse cylinder; a torsion spring 9 is connected between the annular worm 8 and the top cover 4. One end of the torsion spring 9 is connected to the annular worm 8 and the other end is connected to the top cover 4. When the annular worm 8 rotates, the torsion spring 9 deforms accordingly, so that it can apply a reset elastic force to the annular worm 8, which can ensure that the annular worm 8 rotates and resets. Since the upper end of the pull rope 6 is fixed to the top of the support frame 2, when the first driver 3 moves the top cover 4 downward, the distance between the annular worm gear 8 and the top of the support frame 2 increases. At this time, the pull rope 6 will unwind on the outside of the annular worm gear 8, thereby pulling the annular worm gear 8 to rotate. This allows the annular worm gear 8 to drive the two worm wheels 10 on its opposite sides to rotate. Since the two worm wheels 10 are fixedly connected to the corresponding side cover plates 5, and the side cover plates 5 are hinged to the outside of the cover plate, they can drive the two side cover plates 5 to rotate relative to the top cover 4. Thus, the annular worm gear 8 forms a reciprocating rotation structure through the pull rope 6 and the torsion spring 9.

[0028] The system features a separate top cover 4 and side cover plates 5. When the first actuator 3 moves the top cover 4 downwards, the pull rope 6 unwinds on the outside of the annular worm gear 8, causing the annular worm gear 8 to rotate. The rotation of the annular worm gear 8 drives the two meshing worm wheels 10 to rotate synchronously. The rotation of the worm wheels 10 causes their shafts to rotate. Since the shafts are rotatably connected to the side cover plates 5, the rotation of the shafts causes the side cover plates 5 to open or close, thus closing both side cover plates 5 to form a truncated cone-shaped slump cylinder. Concrete is then poured into the side cover plates 5 through the opening 1 on the top cover 4 for on-site slump testing. When not in use, the first actuator 3 can move the top cover 4 upwards, opening the side cover plates 5 for future use. Simultaneously, the opening and closing rotation of the side cover plates 5 facilitates slump testing and allows for quick separation from the concrete.

[0029] Meanwhile, to prevent dust accumulation on the viewing window 7 of the concrete pouring site slump test molding module from affecting the viewing clarity, a groove 12 and two spaced-apart viewing windows 7 are provided on the outer wall of each side cover plate 5. The groove 12 is located between the two viewing windows 7. The shaft of the worm gear 10 is connected to a screw 11 via a bevel gear connector. The screw 11 is rotatably mounted in the groove 12, and a slider is threaded onto the screw 11. At the same time, a cleaning plate 13 is fixed to the slider. The cleaning plate 13 is movably mounted on the outer surface of the two viewing windows 7 for cleaning the viewing windows 7. The range of movement of the screw 11 and the cleaning plate 13 is greater than the area of ​​the two viewing windows 7. Therefore, the rotation of the annular worm 8 will drive the worm wheel 10 to rotate synchronously under the meshing transmission. The worm wheel 10 is nested on the shaft, and the shaft is fixedly connected to the top cover 4. The worm wheel 10 is also fixedly connected to the side cover plate 5. Therefore, when the worm wheel 10 rotates on the shaft, it will synchronously drive the side cover plate 5 to unfold along the direction of rotation. Thus, the screw 11 installed in the side cover plate 5 will revolve along the axis of the worm wheel 10 and the shaft. Since the bevel teeth installed on the surface of the shaft are in a fixed state, When the worm gear 10 drives the screw 11 to revolve together, the bevel teeth installed at the top of the screw 11 will mesh with the bevel teeth on the shaft during the revolution, and drive the screw 11, which is rotatably installed in the side cover plate 5, to rotate synchronously. This, in turn, drives the cleaning plate 13 to move back and forth. Therefore, the rotation of the annular worm gear 8 will not only drive the side cover plate 5 to deflect, but also drive the cleaning plate 13 installed in the side cover plate 5 to move synchronously. Thus, the cleaning plate 13 can clean the two viewing windows 7, thereby avoiding dust accumulation and affecting observation.

[0030] In addition, to address the issue of rapid and uniform distribution of concrete inside the slump test molding module during existing concrete pouring site testing, this embodiment also incorporates a compaction mechanism. This mechanism primarily includes a pressure plate 15. The other end of a second driver 14 passes through the opening 1 and the annular worm gear 8 and is connected to the top of the pressure plate 15. When the second driver 14 is activated, its driving end can drive the pressure plate 15 to move up and down within the slump test cylinder, thereby compacting and flattening the concrete inside the slump test cylinder.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. 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.
