Description

A slump cylinder with a laser distance measuring device

technical field

The utility model relates to the field of concrete equipment, in particular to a slump cylinder with a laser distance measuring device.

Background technique

Concrete slump refers to the workability of concrete. Specifically, it is an index to measure concrete to ensure the normal progress of construction. Work properly. Workability refers to whether the concrete is easy to operate and evenly compacted. It is a very comprehensive performance that includes fluidity, cohesion and water retention. The workability is mainly affected by water consumption per unit volume, water-cement ratio, sand ratio, and several aspects including cement types, aggregate conditions, time and temperature, and admixtures.

In the construction site and laboratory, the slump test of concrete mortar is carried out by using the slump cylinder. The slump test is to put the mixed concrete mixture into the slump cylinder in three layers, Step on the pedal, then tamp the concrete with a tamping rod. After filling, scrape off the excess mixture with a trowel, smooth the mouth of the barrel, and then quickly lift the slump barrel, but ensure that the concrete is not affected by lateral and torsion. Finally, use tools to measure and record the height of the highest point of the concrete stable pile. In the prior art, a movable caliper with a base is often used for measurement, but it is not easy to see the highest point of the measured concrete accurately and quickly, and the scale is not easy to see clearly in a dark environment.

The authorized announcement number is a digital display slump cylinder of CN204925119U, which discloses a slump cylinder with a laser emitter, which emits a horizontal laser through a laser emitter that can move up and down to find a point, and then The reading is carried out through the reading display device, thereby improving the accuracy and reducing the time. But what described laser emitter emits is a beam of light, and concrete is not a regular shape when falling from the slump cylinder, and its highest point is often not easy to determine. If only a thin light is used to find a point, The entire slump cylinder must be moved slowly, and the height of the laser emitter must be adjusted at all times, which is not only difficult to operate, but also difficult to ensure accuracy. To ensure accuracy, the laser beam emitted by the laser emitter must be accurately hit to the highest point and made The edge of the beam just touches the highest point, once the spot appears on the concrete, it is not an accurate measurement. So although this utility model uses a digital display to replace the human eye reading, it cannot be simple, accurate and fast.

Utility model content

Aiming at the above defects of the prior art, the utility model provides a slump cylinder with a laser distance measuring device that has a simple and compact structure, and can quickly and accurately measure the highest point of concrete through reasonable structural settings.

The utility model is realized through the following technical solutions: a slump cylinder with a laser distance measuring device, comprising a conical cylinder body, a handle is provided on the upper part of the conical cylinder body, and a pedal is provided on the lower part of the conical cylinder body plate, the outer wall of the tapered cylinder body is clamped with a laser distance measuring ruler, the laser distance measuring ruler includes a rod-shaped ruler body, one end of the ruler body is provided with a laser rangefinder, and the laser emission window of the laser rangefinder is connected to the The sides of the ruler body are on the same horizontal plane, and there are horizontal air bubbles parallel to the ruler body on the laser distance measuring ruler.

The utility model has a simple structure and includes two parts: a cone-shaped cylinder body and a laser distance measuring ruler. The handle is a structure that is convenient for the user to lift the slump cylinder, and the foot pedal is a structure that is convenient for the user to stabilize the entire slump cylinder with their feet during the tamping process. However, the laser distance measuring ruler of the utility model is a new type of structure, and it is clamped and fixed with the tapered cylinder body for the convenience of carrying. One end of the body is provided with a laser rangefinder, and the laser rangefinder is an instrument for accurately measuring the distance of the target by using a certain parameter of the modulated laser. The pulsed laser rangefinder emits a beam or a sequence of short-lived pulsed laser beams to the target when it is working, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates The distance from the meter to the target.

One side of the ruler body is a flat surface, and the plane where the laser emission window of the laser rangefinder is located is on the same plane as the flat surface of the ruler body, so that the measured distance of the laser rangefinder is not the same as that of the ruler body.

At this time, the bottom surface of the ruler is a broken line or straight-line flat surface structure. By placing the bottom surface on the opening of the cone body or directly Contact with the highest point of concrete, so that the height of the highest point of the concrete pile can be measured. When using the second method for measurement, the user can bend and fold the ruler body at will, which is convenient for moving the horizontal position of the laser rangefinder flexibly, so as to move to the highest point of the concrete pile for measurement more quickly. And there is a damping device at the hinge, so that when the ruler body is folded or pulled apart, it has a certain limit effect, preventing the ruler from being too loose and affecting the measurement effect. The fixed hook is a strip-shaped locking structure, which is perpendicular to the contact surface between the laser range finder and the ruler body. The fixing hook can fix the entire ruler body by clamping a set of opposite sides of the outermost ruler piece, so as to prevent the ruler body from being automatically forced to scatter.

Further, the ruler body is a steel tape structure, and the bottom surface of the ruler tape of the ruler body is at the same level as the laser emission window of the laser rangefinder, and the horizontal air bubble is arranged on the laser rangefinder. Now the ruler body is further optimized and limited to a shrinkable and curled steel tape structure. When measuring, you only need to pull out the ruler tape to form a long strip structure to measure.
