Technical Field

[0001] The utility model relates to the technical field of truck bucket volume measurement, in particular to a truck volume scanning device. Background Art

[0002] Before loading aggregates (stones), the truck bed is measured for volume, which is conducive to loading the amount of aggregates suitable for the truck when loading the aggregates. In the prior art, a laser scanner can be used to measure the cargo volume of a truck, which is more objective and efficient than manual measurement. For example, the invention patent with publication number CN105466370B is a fixed gantry vehicle-mounted material volume measurement method, the invention patent with publication number CN110836636B is a laser scanning train loading detection device, and the utility model patent with publication number CN215114432U is a shield slag metering system based on the earthwork volume measurement of slag trucks; all use laser scanners to achieve volume measurement, but during the measurement process, the vehicle body is in a driving state, and the length of the vehicle body is determined by the vehicle speed. However, the vehicle speed is not constant during driving, so the relative speed between the vehicle body and the laser scanner is also not constant, resulting in a certain error in the measured volume data.

For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] The present invention is further described in detail below in conjunction with the embodiments.

[0025] The specific embodiment of the truck volume scanning device provided by the utility model is as follows:

[0026] See also Figure 1-6 The truck volume scanning device includes a linear rail 1 and a slide 2 sliding along the linear rail 1, wherein two linear rails 1 are arranged in parallel, and both ends of the slide 2 slide along the two linear rails 1 respectively; the slide 2 is perpendicular to the two linear rails 1; both ends of the linear rail 1 are connected with a gantry 8, and the upper end of the gantry 8 is connected to the linear rail 1, and the truck can travel to the bottom of the slide 2 between the gantry 8 at both ends.

[0027] A laser scanner 3 is installed on the lower side of the slide 2, and the laser scanner 3 scans the truck bed at a constant speed along with the slide 2. The laser scanner 3 is connected to a host computer, which obtains scanning information of the laser scanner 3 and outputs volume measurement data.

[0028] In this embodiment, a horizontally rotating annular body 4 and a motor 5 for driving the annular body 4 to rotate are provided; the motor 5 can output a stable rotation speed, which is beneficial to the accuracy of volume measurement. Specifically, a top frame 10 is provided on the upper side of the gantry 8, and the two ends of the top frame 10 are respectively connected to the middle of the upper sides of the two gantry frames 8; two horizontal wheels 9 are rotatably installed on the top frame 10, and the two horizontal wheels 9 are respectively located at the inner sides of the two ends of the annular body 4 and support the annular body 4 to rotate.

[0029] The motor 5 is mounted on the top frame 10, and the output shaft of the motor 5 is connected to a horizontal wheel 9 to drive the horizontal wheel 9 to rotate, thereby causing the annular body 4 to rotate and causing another horizontal wheel 9 to rotate. In this embodiment, the annular body 4 is an annular belt, and the horizontal wheel 9 is a pulley. In other embodiments, the annular body 4 can be a chain, and the horizontal wheel 9 can be a sprocket.

[0030] Two parallel troughs 11 are arranged on both sides of the middle of the top frame 10. The troughs 11 are parallel to the linear track 1. The cross-section of the troughs 11 is U-shaped, and the U-shaped openings are located on the side of the troughs 11 facing away from the top frame 10. A plurality of support plates 12 are connected between the troughs 11 facing the top frame 10 and the top frame 10, and the support plates 12 provide stable support for the troughs 11. The annular body 4 has two straight sections, which are parallel to the linear track 1. The two straight sections of the annular body 4 pass through the two troughs 11 respectively.

[0031] The function of the trough 11 is to ensure the level of the straight section of the annular body 4 and prevent the straight section from hanging and sagging. The two horizontal wheels 9 hold the annular body 4 tightly and ensure the horizontal rotation of the annular body 4, thereby ensuring the uniform rotation of the annular body 4.

[0032] A frame 6 is connected to the upper side of the slide 2, and the length direction of the frame 6 is parallel to the direction of the slide 2 and perpendicular to the linear track 1. A driving column 7 extending into the frame 6 is connected to the outer side of the annular body 4, and the inner width of the frame 6 is slightly larger than the outer diameter of the driving column 7. When the annular body 4 rotates at a constant speed, the driving column 7 is driven to move at a constant speed. When the driving column 7 is located in the straight section of the annular body 4, the slide 2 is driven to move at a constant speed through the frame 6. When the driving column 7 is located in the straight section of the annular body 4 and moves from one end to the other end with the annular body 4, the slide 2 and the laser scanner 3 move from one end to the other end, and the laser scanner 3 completes the scanning of the truck. The driving column 7 moves and turns direction with the annular body 4 outside the horizontal wheel 9, so that the slide 2 turns direction and moves so as to scan the next truck next time.

[0033] In some other embodiments, a roller is sleeved on the outer side of the driving column 7 , and the roller is rotatably connected to the driving column 7 , so that the friction on the frame 6 can be reduced by rolling.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model.
