Description

Technical Field

[0001] The utility model relates to the technical field of concrete fluidity detection, in particular to a high-strength concrete fluidity detection device. Background Technique

[0002] As the core raw material in the field of construction engineering, the performance of concrete is directly related to the strength, durability and safety of building structures. Among them, the fluidity of concrete, that is, its viscosity, is one of the important indicators to measure the performance of concrete. Concrete with appropriate fluidity can flow smoothly during the pouring process, fill every corner of the formwork, and form a uniform and dense concrete block. However, in the actual production process, it is a challenge to judge whether the fluidity of concrete meets the standard. On the one hand, if the viscosity of the concrete is too low, the concrete cannot solidify in time, and the quality of the formed concrete block does not meet the standard, and defects such as cracks and holes are likely to appear, seriously affecting the building quality. On the other hand, if the concrete is too viscous, it is inconvenient to pour during construction and it is difficult to flow smoothly into the formwork, which not only affects the construction efficiency but also causes waste of raw materials. In order to accurately judge whether the fluidity of concrete meets the standard, the traditional method is to adopt the slump test.

[0003] In the prior art, when detecting the fluidity of concrete, usually one staff member loads high-strength concrete into the slump cone, and at the same time another staff member needs to hold the slump cone steady beside to ensure that the slump cone remains in a stable position during the ramming process to prevent it from tipping over. However, this testing process not only requires the assistance of multiple people but also has low efficiency, greatly wasting manpower, so further improvement is needed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a high-strength concrete fluidity detection device, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A high-strength concrete fluidity detection device includes a workbench. A through placing hole is opened in the middle of the upper end of the workbench. A hollow barrel is placed in the placing hole. A control keyboard is fixedly connected to the upper front part of the workbench. Slide grooves with front ends penetrating are opened in the lower parts of the left inner wall and the right inner wall of the workbench. A bottom baffle is slidably connected in the two slide grooves together. The bottom baffle is located directly below the hollow barrel, and the bottom baffle abuts against the lower end face of the hollow barrel but is not fixed. A barrel clamping device is fixedly connected to the upper front part of the workbench. A concrete ramming structure is fixedly connected to the upper left part of the workbench.

[0007] Preferably, the barrel clamping device includes a fixed frame fixedly connected to the front part of the upper end of the workbench. A through limiting sliding opening is formed in the middle of the upper end of the fixed frame. The left end of the fixed frame is fixedly connected to a driver. The output end of the driver penetrates through the middle of the left end of the fixed frame and is fixedly connected to a positive and negative screw rod. The right end of the positive and negative screw rod is movably connected to the fixed frame through a bearing. Clamping components are threadedly movably connected to both the left part and the right part of the outer surface of the positive and negative screw rod. The two clamping components are distributed in left-right mirror symmetry.

[0008] Preferably, the clamping component includes a fixed connecting block. A left-right through threaded hole is formed in the front part of the right end of the fixed connecting block. A limiting sliding block is fixedly connected to the front part of the upper end of the fixed connecting block. A barrel clamping plate is fixedly connected to the rear end of the fixed connecting block.

[0009] Preferably, the fixed connecting block is threadedly movably connected to the positive and negative screw rod through the threaded hole, and the fixed connecting block is slidably connected to the fixed frame through the limiting sliding block and the limiting sliding opening. The two barrel clamping plates do not come into contact with the upper end surface of the workbench. The hollow barrel is located between the two barrel clamping plates.

[0010] Preferably, the concrete tamping structure includes a frame fixedly connected to the left part of the upper end of the workbench. A cylinder is fixedly connected to the upper end of the frame. The output end of the cylinder penetrates through the middle of the upper end of the frame and is fixedly connected to a connecting frame. A compaction tamping head is fixedly connected to the lower end of the connecting frame.

[0011] Preferably, the compaction tamping head is directly above the hollow barrel, and the diameter area of the compaction tamping head is equal to the inner diameter area of the hollow barrel.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, by setting the barrel clamping device, the barrel clamping device is provided with a fixed frame, a limiting sliding opening, a driver, a positive and negative screw rod and a clamping component. Then, the clamping component is provided with a fixed connecting block, a threaded hole, a limiting sliding block and a barrel clamping plate. With the cooperation of these accessories, a person can immediately place the barrel in the placement hole formed in the workbench, making the lower end of the hollow barrel tightly abut against the bottom baffle. Thus, by starting the driver through the control keyboard, the clamping and fixing of the hollow barrel can be automatically completed. Then, the stirred high-strength concrete can be poured into the barrel, so that the feeding and clamping operations can be completed by one person without the assistance of others, saving manpower and time;

[0014] 2. In the present utility model, a frame body, a cylinder, a connecting frame, and a compaction rammer are provided on the concrete compaction structure. The compaction rammer is located directly above the hollow barrel body and has the same area as the inner diameter area of the hollow barrel body. With the cooperation of these components, through the action of the compaction rammer, the voids inside the concrete material can be effectively reduced, making the concrete more compact, thereby improving its density. Therefore, while ensuring the stability of the hollow barrel body during the detection process, by removing the bottom baffle, the compacted concrete inside the hollow barrel body flows out, enabling a single worker to record the time required for the concrete to fill a receiving container of a certain volume. The shorter the time, the better the fluidity of the concrete; the longer the time, the poorer the fluidity. Thus, manpower waste is avoided and the detection efficiency of the concrete fluidity is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] A high-strength concrete fluidity detection device includes a workbench 1. A through placement hole 2 is opened in the middle of the upper end of the workbench 1. A hollow barrel 3 is placed in the placement hole 2. A control keyboard 6 is fixedly connected to the upper front part of the workbench 1. Sliding grooves 4 that penetrate the front end are opened in the lower part of the inner left wall and the lower part of the inner right wall of the workbench 1. A bottom baffle 5 is slidably connected in the two sliding grooves 4 together. The bottom baffle 5 is located directly below the hollow barrel 3, and the bottom baffle 5 abuts against the lower end surface of the hollow barrel 3 but is not fixed. A barrel clamping device 7 is fixedly connected to the upper front part of the workbench 1. A concrete tamping structure 8 is fixedly connected to the upper left part of the workbench 1.

[0025] In this embodiment, the barrel clamping device 7 includes a fixed frame 71. The fixed frame 71 is fixedly connected to the front part of the upper end of the workbench 1. A through limiting sliding opening 72 is formed in the middle of the upper end of the fixed frame 71. The left end of the fixed frame 71 is fixedly connected to a driver 73. The output end of the driver 73 penetrates through the middle of the left end of the fixed frame 71 and is fixedly connected to a forward and reverse screw rod 74. The right end of the forward and reverse screw rod 74 is movably connected to the fixed frame 71 through a bearing. Both the left part and the right part of the outer surface of the forward and reverse screw rod 74 are threadedly movably connected with clamping assemblies 75. The two clamping assemblies 75 are distributed in left-right mirror symmetry. The clamping assembly 75 includes a fixed connection block 751. A left-right through threaded hole 752 is formed in the front part of the right end of the fixed connection block 751. A limiting sliding block 753 is fixedly connected to the front part of the upper end of the fixed connection block 751. A barrel clamping plate 754 is fixedly connected to the rear end of the fixed connection block 751. The fixed connection block 751 is threadedly movably connected to the forward and reverse screw rod 74 through the threaded hole 752. The fixed connection block 751 is slidably connected to the fixed frame 71 through the limiting sliding block 753 and the limiting sliding opening 72. The two barrel clamping plates 754 do not contact the upper end surface of the workbench 1. The hollow barrel 3 is located between the two barrel clamping plates 754.

[0026] Through the above solution: Place the hollow barrel 3 in the placement hole 2 and press it tightly against the bottom baffle 5. Then, the operator starts the driver 73 to work through the control keyboard 6. The driver 73 drives the forward and reverse screw rod 74 to rotate. Since the threaded hole 752 on the fixed connection block 751 is in threaded cooperation with the forward and reverse screw rod 74, and the rotation of the fixed connection block 751 is restricted by the sliding of the limiting sliding block 753 in the limiting sliding opening 72, the two fixed connection blocks 751 move towards each other along the forward and reverse screw rod 74, driving the barrel clamping plates 754 to move towards each other, so as to quickly clamp the hollow barrel 3 and realize the fixation of the hollow barrel 3. After the barrel is fixed, the operator can pour the stirred concrete into the hollow barrel 3 alone, which is convenient for operation.

[0027] In this embodiment, the concrete tamping structure 8 includes a frame body 81. The frame body 81 is fixedly connected to the left part of the upper end of the workbench 1. A cylinder 82 is fixedly connected to the upper end of the frame body 81. The output end of the cylinder 82 penetrates through the middle of the upper end of the frame body 81 and is fixedly connected to a connecting frame 83. A compaction rammer 84 is fixedly connected to the lower end of the connecting frame 83. The compaction rammer 84 is located directly above the hollow barrel 3. The diameter area of the compaction rammer 84 is equal to the inner diameter area of the hollow barrel 3.

[0028] Through the above solution: The operator starts the operation of the cylinder 82 by controlling the keyboard 6. The output end of the cylinder 82 pushes the connecting frame 83 to move downward. The connecting frame 83 drives the compaction ram 84 to move downward. Since the compaction ram 84 is located directly above the hollow barrel 3 and its diameter area is equal to the inner diameter area of the barrel, the compaction ram 84 can extend into the barrel to compact the concrete. Therefore, one person can complete the operations of fixing the hollow barrel 3 and compacting the concrete, saving manpower and time, improving the efficiency of the concrete fluidity detection process. In addition, the mechanized fixing and compaction methods can provide relatively stable and consistent conditions, which helps to improve the accuracy and reliability of the detection results.

[0029] It should be noted that the present utility model is a device for detecting the fluidity of high-strength concrete. During use, when the staff needs to detect the fluidity of high-strength concrete, first place the hollow barrel 3 in the placement hole 2 opened on the workbench 1 and above the bottom baffle 5. Start the driver 73 by controlling the keyboard 6. The driver 73 drives the forward and reverse screw rod 74 to rotate, so that the barrel clamping plates 754 of the two clamping components 75 move towards each other, and the hollow barrel 3 can be clamped tightly. Then pour the high-strength concrete into the clamped hollow barrel 3. Then the operator starts the operation of the cylinder 82 by operating the control keyboard 6. The cylinder 82 pushes the connecting frame 83 to drive the compaction ram 84 to move downward, and the concrete in the barrel can be compacted. Finally, the operator can pull out the bottom baffle 5 to let the concrete in the hollow barrel 3 flow out naturally. The operator can observe and record the flow rate, shape, etc. of the concrete flowing out to judge its fluidity. Therefore, through the above steps, one person can efficiently and quickly complete the detection of the fluidity of high-strength concrete by using the automated and mechanized components of the detection device.
