Description

Technical Field

[0001] The utility model relates to the technical field of detection of concrete mixtures, in particular to a detection device for the passing performance of gaps in recycled concrete. Background Technique

[0002] The utility model patent with the publication number of CN209727694U discloses a detection device for the passing performance of gaps in concrete mixtures, which includes a concrete slump cone, a smooth square bottom plate and a J-ring flow meter. The J-ring flow meter is placed at the center of the bottom plate, and the concrete slump cone and the J-ring flow meter are concentrically placed at the center of the bottom plate. Concentric scale lines are provided on the bottom plate along the center of the bottom plate outwards. An automatic lifting device capable of driving the concrete slump cone and the J-ring flow meter to move is arranged on the horizontal planes on both sides of the bottom plate.

[0003] The following deficiencies exist in the above patent:

[0004] Both the J-ring flow meter and the concrete slump cone are installed on the slider through hanging rods. Therefore, the relative positions of the J-ring flow meter and the concrete slump cone are fixed. When concrete is poured into the concrete slump cone and then the concrete slump cone is immediately lifted upwards by 30 mm, the J-ring flow meter and the concrete slump cone rise synchronously. Therefore, when pouring concrete into the concrete slump cone and only lifting the concrete slump cone upwards by 30 mm while the J-ring flow meter remains in contact with the bottom plate and does not move, at this time, the concrete slump cone needs to be disassembled. That is, when performing a test with a J-ring flow meter, the J-ring flow meter needs to be disassembled and reinstalled. Therefore, the detection test is not convenient enough.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the drawings.

[0023] The present utility model provides a device for detecting the passing performance of recycled concrete gaps. Please refer to Figures 1-4 , which includes a bottom plate 18. The bottom plate 18 is provided with annular scale lines. An elevating mechanism is installed on the bottom plate 18, and a concrete slump cone 8 is installed on the elevating mechanism. It also includes a J-ring flowmeter sleeved on the concrete slump cone 8. The J-ring flowmeter is composed of a first semi-ring body 10 and a second semi-ring body 9. The first semi-ring body 10 and the second semi-ring body 9 are respectively connected with a first propulsion component and a second propulsion component;

[0024] Through the first propulsion component and the second propulsion component, the J-ring flowmeter can be driven away from the concrete slump cone 8.

[0025] The lifting mechanism includes an L-shaped support column 1 fixedly installed on the bottom plate 18. A servo motor 2 is installed at the top end of the L-shaped support column 1. The output shaft of the servo motor 2 is connected to a lead screw 3 through a coupling. A bearing seat 6 is fixedly installed on the bottom plate 18. The bearing seat 6 is rotationally connected to the bottom end of the lead screw 3 through a bearing. A lifting block 4 is threadedly connected to the lead screw 3. Specifically, an internally threaded tube 5 is fixedly installed on the lifting block 4. The inner wall of the internally threaded tube 5 is threadedly connected to the lead screw 3. A support rod 7 is welded to the end of the lifting block 4. The concrete slump cone 8 is installed at the end of the support rod 7. The lifting block 4 is slidably connected to the L-shaped support column 1. Specifically, a through hole 19 is formed in the L-shaped support column 1, and the inner wall of the through hole 19 is slidably connected to the lifting block 4.

[0026] A first support connection seat is welded to the outer wall of the concrete slump cone 8. The end of the support rod 7 is inserted into the first support connection seat, and the support rod 7 and the first support connection seat are fixed by bolts.

[0027] The first propulsion assembly includes a first fixed block 101 welded to the outer wall of the first semi-ring body 10. The first fixed block 101 is detachably connected to a first push rod 11. Specifically, a second support connection seat 13 is fixedly installed on the first fixed block 101. The first push rod 11 is inserted into the inner wall of the second support connection seat 13, and the first push rod 11 and the second support connection seat 13 are fixed by bolts. The other end of the first push rod 11 is detachably connected to the L-shaped support column 1. Specifically, a third support connection seat 12 is welded to the L-shaped support column 1. The first push rod 11 is inserted into the inner wall of the third support connection seat 12, and the first push rod 11 and the third support connection seat 12 are fixed by bolts; as Figure 1 shown, the second semi-ring body 9 and the first semi-ring body 10 are butted to form a J-ring flowmeter. Rod bodies are installed at the bottoms of the second semi-ring body 9 and the first semi-ring body 10, and the rod bodies are slidably connected to the bottom plate 18. At this time, when the lifting mechanism drives the concrete slump cone 8 to contact the bottom plate 18, concrete is injected into the concrete slump cone 8, and then the lifting mechanism drives the concrete slump cone 8 to rise; when it is necessary to perform a test without a J-ring flowmeter, both the first push rod 11 and the second push rod 15 contract to drive the first semi-ring body 10 and the second semi-ring body 9 away from the concrete slump cone 8, so that a test without a J-ring flowmeter can be performed.

[0028] The second propulsion assembly includes a second fixing block 91 welded to the outer wall of the second semi-ring body 9. The second fixing block 91 is detachably connected to a second push rod 15. Specifically, a fourth support connection seat 14 is fixedly installed on the second fixing block 91. The second push rod 15 is inserted into the inner wall of the fourth support connection seat 14, and the second push rod 15 and the fourth support connection seat 14 are fixed by bolts. The other end of the first push rod 11 is detachably connected to a vertical plate 17. Specifically, a fifth support connection seat 16 is fixedly installed on the vertical plate 17. The second push rod 15 is inserted into the inner wall of the fifth support connection seat 16, and the second push rod 15 and the vertical plate 17 are fixed by bolts. The vertical plate 17 is welded to the bottom plate 18.

[0029] During specific use, as Figure 1 shown, the servo motor 2 is started to drive the lead screw 3 to rotate, thereby driving the lifting block 4 to descend. The concrete slump cone 8 descends synchronously with the lifting block 4 until the concrete slump cone 8 contacts the bottom plate 18. Concrete is poured into the concrete slump cone 8, and then the servo motor 2 runs in the reverse direction to drive the concrete slump cone 8 to rise, thereby obtaining the J-ring spread with the J-ring flowmeter;

[0030] The first push rod 11 and the second push rod 15 both contract to drive the first semi-ring body 10 and the second semi-ring body 9 away from the concrete slump cone 8. Then, concrete is poured into the concrete slump cone 8, and then the concrete slump cone 8 is driven to rise through the lifting mechanism, and the slump spread is obtained again. Thus, the gap passability is calculated based on the slump spread and the J-ring spread.

[0031] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources.
