Description

Technical Field

[0001] The utility model relates to the technical field of aggregate measurement, in particular to a portable device for measuring three-dimensional data of aggregate. Background Art

[0002] Aggregates play the role of skeleton (coarse aggregate) and filler (fine aggregate) in cement concrete and asphalt mixtures, so different particle sizes play different roles in engineering. The morphological characteristics, distribution, and gradation of aggregates play a decisive role in the durability, compression resistance, stability, and rutting resistance of the pavement. At present, the quantitative evaluation indexes for aggregate morphological characteristics include the axial coefficient A=L / W, where L is the length of the major axis of the particle equivalent ellipse, and W is the width of the minor axis of the particle equivalent ellipse. The larger the axial coefficient, the greater the needle-like nature of the particle. Generally, a ruler is used to measure the length of each axis. This method can evaluate the advantages and disadvantages of aggregates for construction in two dimensions. Although it is simple, it does not reflect the situation comprehensively.

[0003] In order to obtain more comprehensive data, the three-dimensional size of the aggregate can be measured. Currently, there is a three-dimensional data acquisition technology that uses infrared lasers combined with area array cameras to achieve rapid acquisition of detection particle data information. However, this method is too expensive and has strict requirements on the measurement technology and environment. In addition, the device is large and inconvenient to carry, making it unsuitable for convenient collection of construction site data. Utility Model Content

[0022] Example

[0023] like Figures 1 to 3 As shown, an embodiment of the utility model provides a portable device for measuring three-dimensional data of aggregates, including three mounting plates 1, two groups of sliding components and two pressing plates 5; the three mounting plates 1 are vertically connected to each other in pairs, and a group of scale lines are provided at the intersecting edges of each two mounting plates 1, and the three groups of scale lines are respectively arranged along the X, Y and Z axis directions; the two groups of sliding components have the same structure and are respectively arranged on two of the mounting plates 1, the sliding components include slide rails and sliders 4, the slide rails are fixed on the plate surface of the mounting plate 1, the sliders 4 are slidably connected to the slide rails, the slide rails in the two groups of sliding components are perpendicular to each other and are located on the same horizontal plane; the two pressing plates 5 are respectively fixed to the two sliders 4, and the pressing plates 5 are vertically arranged to the slide rails, the two pressing plates 5 are staggered with each other, and the sliders 4 are used to drive the pressing plates 5 to move along the slide rails to adjust the position of the pressing plates 5, so that the pressing plates 5 contact the aggregate to be measured for measurement.

[0024] In this embodiment, the aggregate to be measured is placed on one of the mounting plates 1, and two sliders 4 are slid so that the two pressing plates 5 are close to each other and contact the aggregate to be measured, and the two pressing plates 5 are used to position the length and width of the aggregate to be measured. Figure 2 The three groups of scale lines 2 actually correspond to the dimensional data of the length, width and height directions of the aggregate to be measured. The accuracy of the scale value on each scale line 2 is 1mm. The length and width data of the aggregate to be measured are measured by observing and reading the distance readings corresponding to the two pressing plates 5 moving to the scale lines 2 set in the length direction and the width direction. Finally, the height data of the aggregate to be measured is measured by observing the scale values ​​corresponding to the scale lines 2 in the height direction and the top level of the aggregate, thereby realizing the overall measurement process of the three-dimensional data of the aggregate. The whole measurement process is very simple and convenient, and when not in use, the slider 4 can be removed from the guide rail to reduce the size of the device. It has the advantages of easy carrying and low cost, and is worthy of promotion.

[0025] Among them, in order to facilitate disassembly and carrying, threaded mounting holes are provided on two adjacent sides of one of the mounting plates 1, and fixing screws are threadedly connected on the side walls of the other two mounting plates 1 that are perpendicular to the threaded mounting holes. The three mounting plates 1 are detachably connected by fixing screws. When not being inspected, the three mounting plates 1 can be disassembled from each other for easy carrying.

[0026] In order to facilitate observation of the scale line 2, the three mounting plates 1 are made of transparent plastic. In order to reduce the overall weight of the device, the guide rails and the slider 4 are made of lightweight plastic.

[0027] Specifically, Figure 2 and Figure 3 As shown, the guide rail includes a mounting groove 31 fixed on the mounting plate 1, a slide rail seat 32 is fixed in the middle of the mounting groove 31, and a slide groove 41 matching the slide rail seat 32 is opened on the side wall of the slider 4 facing the guide rail 4. The slider 4 is slidably connected to the slide rail seat 32 through the slide groove 41. The set slide groove 41 and the slide rail seat 32 can guide the slider 4 and facilitate the installation and removal of the slider 4.

[0028] Furthermore, considering that the slider 4 may detach from the mounting groove 31 during the movement along the slide rail seat 32, the slide groove 41 is configured to be dovetail-shaped, and the shape of the slide rail seat 32 is matched with the slide groove 41. With this configuration, the dovetail-shaped slide groove 41 can be used to cooperate with the slide rail seat 32 to achieve the slider 4 being clamped on the slide rail seat 32 to avoid detachment during movement, so that the slider 4 can be inserted or withdrawn from the tail of the slide rail seat 32.

[0029] Further, such as Figure 4 As shown, in order to be able to position the pressure plate 5 to the position in contact with the aggregate for convenient measurement, a locking assembly for locking its moving position is provided on the slider 4, and the locking assembly includes a knob 6 and a positioning screw, the positioning screw is coaxially fixed with the knob 6, the positioning screw is threadedly connected to the slider 4, and the end of the positioning screw away from the knob 6 extends into the slide groove 41 and abuts against the slide rail seat 32; before measurement, the positioning screw is loosened by the knob 6 so that the end of the positioning screw no longer contacts the slide rail seat 32, and then the pressure plate 5 is driven to move to the position in contact with the aggregate to be measured by sliding the slider 4, and the positioning screw is tightened by the knob 6 at this time, so that the end of the positioning screw contacts the slide rail seat 32, and since the slide groove 41 and the slide rail seat 32 are both dovetail-shaped, the positioning screw can lock the moving position of the slider 4 by friction, thereby facilitating subsequent measurement.

[0030] Furthermore, considering that when the slider 4 and the pressure plate 5 are used to clamp and measure the aggregate to be measured, the volume of the aggregate to be measured is large, so that the pressure plate 5 is located exactly at the edge of the mounting plate 1. At this time, the positioning screw on the slider 4 is difficult to position the slider 4. Therefore, the mounting groove 31 and the slide rail seat 32 are extended to the outside of the edge of the mounting plate 1. Such a setting can facilitate the locking of the position of the slider 4 when detecting large-volume aggregates.

[0031] Furthermore, in order to increase the contact surface between the pressing plate 5 and the aggregate to be tested so that the pressing plate 5 can contact the surface of the aggregate to be tested more evenly, the two pressing plates 5 are both configured as comb plates, and the teeth of the two comb plates are staggered.

[0032] In summary, the utility model has a simple structure and a reasonable design. The measuring device as a whole is similar to a small plastic box, and has the advantages of small size, light weight, easy to carry, simple operation and low cost. In addition, when measuring the three-dimensional data of aggregates, aggregates of different specifications can be measured with a measuring box of suitable size, thereby ensuring the universality of the device and the accuracy of the measurement results.

[0033] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
