[0018] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0019] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0020] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0021] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0022] In response to the above problems, an embodiment of the present application provides a concrete slump measuring device. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 The concrete slump measuring device shown includes: a chassis 1, a vertical pole 2, a sleeve 3, a cross bar 4, and a telescopic ruler 5. In this device, the chassis 1 is a steel plate with a length × width × thickness of 50 × 50 × 2 mm. Then, the vertical pole 2 is connected to the chassis 1. The vertical pole 2 can be connected to the chassis 1 by fixed welding or by threaded connection. Both have their advantages: one connection is stable, and the other is convenient for assembly and disassembly. The sleeve 3 is connected to the vertical pole 2, and the cross bar 4 is connected to the sleeve 3. The vertical pole 2 is a 50 cm long Φ20 mm screw rod, and the sleeve 3 is a sleeve with internal threads, which cooperates with the screw rod thread so that the sleeve 3 can be rotated and tightened on the vertical pole 2. The telescopic ruler 5 is slidably set on the cross bar 4, and the telescopic ruler 5 is vertically facing the surface where the chassis 1 is located.

[0024] In this application, before measuring the slump, the working chassis 1 is placed on a flat surface, a slump bucket is placed, and concrete is loaded into the slump bucket; the crossbar 4 is rotated so that the crossbar 4 is located above the slump bucket, and the telescopic ruler 5 is pulled down to measure the distance between the crossbar 4 and the top of the slump bucket; the slump bucket is then raised to allow the concrete to fall naturally. After it stabilizes, the telescopic ruler 5 is pulled again to the concrete surface. The measured height at this time is subtracted from the distance between the crossbar 4 and the top of the slump bucket, and the reading is the actual measured slump of the concrete on site. This device uses the telescopic ruler 5 to measure on a working chassis 1, avoiding the problems of employees manually measuring with a ruler, which is inconvenient to operate and has inaccurate readings. It can minimize measurement time while improving detection accuracy.

[0025] In one embodiment, Figure 2 A more intelligent approach is to replace the telescopic ruler 5 with a distance sensor matrix 6. A motor 9 is connected to the upright pole 2, and the sleeve 3 is connected to the rotating shaft of the motor 9. A display screen 7 integrating display and control is provided above the distance sensor matrix 6, and the display screen 7 is connected to the distance sensor matrix 6. The distance sensor matrix 6 is composed of nine infrared distance sensors arranged in a nine-square grid, and a pressure sensor 8 is provided at the bottom of the chassis 1 and connected to the display screen 7. The motor 9 is connected to the display screen 7.

[0026] In the present application, the sleeve 3 is fixed at a fixed height position. Before the slump is measured, the working chassis 1 is placed on a flat ground, the slump bucket is placed, and the concrete is loaded into the slump bucket. At this time, the pressure sensor 8 detects that the equipment is being operated, and the controller in the display screen 7 enters the timing state, which is actually to leave time for the staff to take out the slump bucket. When the slump bucket is taken out, the timing is just right. The controller in the display screen 7 controls the motor 9 to rotate one circle, and the multiple sensors on the ranging sensor matrix 6 scan the collapse pile to measure the height of the collapse pile, and select the highest one as the final presentation data on the display screen 7. The reason why multiple ranging sensor matrices 6 are set up is to avoid the highest point being detected when the collapse pile is in different positions. Of course, at a high cost, the ranging sensor matrix 6 can be replaced with a visual sensor, and then the relevant data of the image collected by the visual sensor is measured through a designed program and converted into time measurement data. In this way, the device uses a distance measuring sensor to perform measurements on a working chassis 1, avoiding the problem of employees manually measuring with a ruler, which is inconvenient to operate and inaccurate readings. It can reduce the measurement time as much as possible while improving the detection accuracy.

[0027] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
