Description

Technical Field

[0001] This utility model relates to the field of box material transfer technology, and in particular to a positioning device for a transfer truck used in intelligent overhead crane transportation. Background Technology

[0002] The starter culture plays a crucial role in the brewing of baijiu (Chinese liquor). It is a saccharifying and fermenting agent used in the brewing process, typically cultivated from grains or beans through specific techniques. It is rich in microorganisms, such as molds and yeasts, which break down the starch and protein in the grains to produce sugars and amino acids, ultimately leading to fermentation and the production of alcohol and other flavor compounds.

[0003] After the koji (fermentation starter) is prepared in the koji-making workshop, it needs to be temporarily stored in koji powder boxes. These boxes are neatly arranged in an array on the workshop floor and are then transferred when brewing is required. Because the koji powder boxes are numerous and heavy, the current method of transferring them is mainly done manually using overhead cranes. Manual crane operation relies on the operator's vision to position and move the transport trucks. It is evident that manual crane operation is inefficient and prone to errors. Therefore, manual cranes are gradually being replaced by intelligent cranes.

[0004] The application of powder box transfer in intelligent cranes presents the following problems: First, because the crane can only move horizontally in the longitudinal and lateral directions and vertically in a lifting motion, but cannot rotate, there are strict requirements for the parking posture of the transfer truck, requiring the transfer truck to be parallel to the powder boxes; since the lengths of the two powder boxes are matched with the width of the transfer truck, refer to... Figure 1 When the transfer truck (3) is parked at an angle, the width of the transfer truck (3) is not enough to accommodate the two boxes (4), which causes the powder box to tip over, making the transfer more difficult; secondly, the intelligent vehicle cannot locate the position of the car, so it cannot accurately transfer the powder box into the car. Utility Model Content

[0005] To address the technical problems of the inability to locate the trolley position during intelligent overhead crane transport of powder boxes and the difficulty in parking the transfer truck, this utility model provides a transfer truck positioning device for intelligent overhead crane transport.

[0006] The technical solution adopted in this utility model is: a positioning device for a transfer freight car used in intelligent overhead crane transportation includes:

[0007] The material area contains several boxes.

[0008] The parking area is located next to the material area and is used to park transport trucks carrying containers.

[0009] The first positioning component is arranged at the rear of the transfer truck to ensure that the transfer truck and the container are parallel to each other and to detect the longitudinal position of the transfer truck in the parking area. The first positioning component includes two first detection plates arranged at a certain distance from the rear of the transfer truck and a first positioning bracket arranged at a certain distance from the first detection plates. Two first sensors that match the first detection plates are provided on the first positioning bracket.

[0010] The second positioning component is placed on any side of the transfer truck to detect the lateral position of the transfer truck within the parking area.

[0011] Furthermore, a first elongated hole is vertically provided on the first positioning bracket, and the first sensor is fixed to the first elongated hole by bolts.

[0012] Furthermore, the first sensor is a point laser rangefinder.

[0013] Furthermore, the first testing plate is made of stainless steel.

[0014] Furthermore, the second positioning component includes two second detection plates arranged at a certain distance on the side of the transfer truck and a second positioning bracket arranged at a certain distance from the second detection plates. The second positioning bracket is equipped with two second sensors that match the second detection plates.

[0015] Furthermore, a second elongated hole is vertically provided on the second positioning bracket, and the second sensor is fixed to the second elongated hole by bolts.

[0016] Furthermore, the second sensor is a point laser rangefinder.

[0017] Furthermore, the second testing plate is made of stainless steel.

[0018] Furthermore, the parking area is equipped with reverse barriers to prevent transport trucks from rolling backward.

[0019] Furthermore, indicator lights are installed at both ends of the rear of the parking area to guide drivers to park their transport trucks correctly in the parking area.

[0020] The beneficial effects of this utility model are:

[0021] 1. The positioning device for the transfer truck of this utility model can detect the parking posture of the transfer truck in real time, so that the transfer truck and the container are kept parallel, thereby facilitating the intelligent crane to accurately and neatly lift the container into the transfer truck and avoid misalignment or tipping of the container; in addition, the positioning device for the transfer truck can also accurately locate the position of the transfer truck, thereby cooperating with the intelligent crane to achieve accurate transfer of the container.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The following is in conjunction with the appendix Figures 2-4 The present invention will be further described below.

[0037] Example 1

[0038] In view of the technical problems existing in the background art, the present invention provides a positioning device for a transfer truck used in intelligent overhead crane transportation.

[0039] In the specific technical solution, refer to Figure 2 The positioning device for the transfer truck used in intelligent overhead crane transportation includes a material area 1 and a parking area 2 arranged next to the material area 1. The material area 1 is stacked with several boxes 4, and the parking area 2 is used to park the transfer truck 3 carrying the boxes 4. In this embodiment, the boxes are koji powder boxes, and the length of two side-by-side koji powder boxes matches the width of the cargo box of the transfer truck 3. The crane in this embodiment is an intelligent crane, that is, it does not require human operation.

[0040] The above technical solution is the on-site layout structure of the koji powder transportation workshop. Since the overhead crane can only move horizontally in the longitudinal and lateral directions and vertically in a lifting and lowering manner, but cannot rotate, there are strict requirements for the parking posture of the transfer truck 3, requiring it to be parallel to the koji powder box; furthermore, it is necessary to achieve precise positioning of the transfer truck. Therefore, to address the above technical problems, this utility model makes the following further improvements:

[0041] Specifically, refer to Figure 3 The present invention also includes a first positioning component 5 and a second positioning component 6; the first positioning component 5 is arranged at the rear of the transfer truck 3 to ensure that the transfer truck 3 and the box 4 are parallel to each other and to detect the longitudinal position of the transfer truck 3 in the parking area 2; the second positioning component 6 is arranged on any side of the transfer truck 3 to detect the lateral position of the transfer truck 3 in the parking area 2.

[0042] The specific design of the first positioning component 5 refers to... Figure 3 and Figure 4 The first positioning component 5 includes two first detection plates 301 arranged at a certain distance from the rear of the transfer truck 3, and a first positioning bracket 501 arranged at a certain distance from the first detection plates 301. Two first sensors 502 matching the first detection plates 301 are mounted on the first positioning bracket 501. The second positioning component 6 includes two second detection plates 302 arranged at a certain distance from the side of the transfer truck 3, and a second positioning bracket 601 arranged at a certain distance from the second detection plates 302. Two second sensors matching the second detection plates are mounted on the second positioning bracket 601. The structure of the second positioning bracket 601 is the same as that of the first positioning bracket 501.

[0043] Working principle: The first positioning bracket 501 is fixed to the workshop floor and perpendicular to the box body 4. Two first sensors 502 on the first positioning bracket 501 detect the distance between the bracket and the transfer truck 3, thus determining the degree of tilt of the transfer truck 3. The greater the difference in distance values ​​detected by the two first sensors 502, the more tilted the transfer truck 3 is; the smaller the difference in distance values ​​detected by the two first sensors 502, the more upright the attitude of the transfer truck 3 is, meaning the transfer truck 3 is closer to being parallel to the box body 4. Technicians can set a threshold in the central control system according to different vehicle models. When the difference in distance values ​​detected by the two first sensors 502 is less than the threshold, it indicates that the parking posture of the transfer truck 3 is correct; when the difference in distance values ​​detected by the two first sensors 502 is greater than the threshold, it indicates that the parking posture of the transfer truck 3 is tilted and further adjustment is needed. The first sensor 502 can detect the longitudinal position of the transfer truck 3 in the parking area 2, and the second sensor can detect the lateral position of the transfer truck 3 in the parking area 2. The first and second sensors work together to realize the positioning of the transfer truck 3 in the X and Y directions, and feed this positioning information back to the central control. The central control then sends the positioning information to the intelligent driving system, so that the intelligent driving system can read the accurate position of the transfer truck 3.

[0044] As can be seen from the above structure and working principle, the transfer truck positioning device of this utility model can detect the parking posture of the transfer truck in real time, so that the transfer truck and the container are kept parallel, thereby facilitating the intelligent crane to accurately and neatly lift the container into the transfer truck, avoiding the misalignment or tipping of the container; in addition, the transfer truck positioning device can also accurately locate the positional relationship of the transfer truck, thereby cooperating with the intelligent crane to achieve precise transfer of the container.

[0045] To improve the versatility of the positioning device for transport trucks, refer to Figure 4 In this embodiment, a first elongated hole 503 is vertically provided on the first positioning bracket 501, and the first sensor 502 is fixed to the first elongated hole 503 by bolts; a second elongated hole is vertically provided on the second positioning bracket 601, and the second sensor is fixed to the second elongated hole by bolts. Because different transport trucks have different models and therefore different heights, the first sensor 502 is slid within the elongated hole 503 to a suitable height, and then fixed with bolts, so that the first sensor 502 is at the same horizontal position as the detection plate on the transport truck 3. In this embodiment, the first sensor 502 and the second sensor are preferably point laser ranging sensors. The first detection plate 301 and the second detection plate 302 are preferably made of 304 stainless steel.

[0046] To prevent the transfer truck from rolling backward due to driver error, refer to Figure 4 Therefore, in this embodiment, a reversing barrier 7 is also provided in the parking area 2 to prevent the transport truck 3 from rolling backward.

[0047] Example 2

[0048] To make it easier for the driver to adjust the posture of the transfer truck 3, refer to Figure 4 Based on Embodiment 1, this embodiment also provides indicator lights 8 at both ends of the rear of the parking area 2. The indicator lights 8 are used to guide the driver to park the transfer truck 3 correctly in the parking area 2.

[0049] Operating Principle: The indicator lights have two display colors: red and green. They are connected to the central control system, and the driver can observe them through the rearview mirror on the transfer truck 3. When the transfer truck 3 tilts to the right, the first sensor sends feedback to the central control system, which then controls the left indicator light to turn red. Once the driver observes the left indicator light turn red, they should adjust the angle of the transfer truck to the left until both indicator lights are green, indicating a correct parking posture, and the engine can be turned off to await the transfer of the container. When there are no vehicles in parking area 2, both indicator lights will be red.

[0050] As can be seen from the above structure and working principle, the transfer truck positioning device of this utility model can guide the driver to adjust the angle of the transfer truck through indicator lights, which greatly shortens the parking time, reduces the parking difficulty, and improves parking efficiency.

[0051] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
