Description

Technical Field

[0001] This utility model relates to the field of coking production technology, and more specifically, to a positioning system for the four main vehicles in coking oven production. Background Technology

[0002] In the coking industry, the environment of coke oven production workshops is harsh, with safety hazards such as high temperatures, toxic and harmful gases, and dust. These hazards pose significant risks to the physical and mental health of employees, resulting in difficulties in recruiting coke oven top operators. The four main vehicles (pushing car, coke quenching car, coal charging car, and coke quenching car) are the four most commonly used pieces of equipment in coke oven production workshops, and their positioning is a prerequisite for automated coke oven production. Traditionally, workers need to manually position these vehicles to meet production demands, requiring multiple starts and resulting in high labor costs and low positioning quality. To further free up workers' hands and ensure their safety, existing solutions aim to achieve unmanned operation of the four main vehicles by developing positioning technology, such as using GPS. However, this method has low accuracy, high cost, and is highly susceptible to external influences.

[0003] Based on the aforementioned technical issues, there is an urgent need for a low-cost, high-precision positioning system for four vehicles that requires no manual operation. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a positioning system for the four main vehicles in coke oven production, so as to solve the problems of high cost, low accuracy and great susceptibility to external influences in the existing solution of using GPS positioning technology to locate the four main vehicles.

[0005] The coke oven production positioning system provided by this utility model includes a laser rangefinder and a reflector; wherein, the laser rangefinder is connected to the end of the coke oven via a movable bracket, and the reflector is connected to the main beam of the vehicle to be positioned; and...

[0006] The laser emitted by the laser rangefinder is aligned with the reflector.

[0007] Alternatively, in an optional configuration, two laser rangefinders are provided; and,

[0008] The two laser rangefinders are respectively mounted on the ends of the coke oven on both sides.

[0009] Alternatively, the movable support may include an upper support plate and a lower support plate, the upper support plate and the lower support plate being hinged together by a pivot, and the laser rangefinder being fixed to the upper support plate.

[0010] Alternatively, the upper support plate may have a positive V-shape and the lower support plate may have an inverted V-shape; and the side of the upper support plate away from the laser ranging sensor may be hinged to the middle of the lower support plate.

[0011] Alternatively, an optional structure may be provided with a positioning waist hole on the upper support plate and a positioning hole on the lower support plate, wherein the upper support plate is fixed to the lower support plate by positioning bolts in conjunction with the positioning waist hole and the positioning hole.

[0012] Alternatively, the movable bracket may include a fixed plate fixed to the end, a turntable provided on the fixed plate, and the lower support plate being rotatably connected to the fixed plate via the turntable.

[0013] Alternatively, the reflector can be connected to the vehicle to be positioned via a movable connecting assembly; and the movable connecting assembly includes a vertical slide rail on which a first slider is slidably connected, and the reflector is connected to the first slider.

[0014] Alternatively, the movable connection assembly may include a transverse slide rail fixed to the vehicle to be positioned, and a second slider fixed to the end of the vertical slide rail, the second slider being slidably connected to the transverse slide rail.

[0015] Furthermore, an optional configuration is that at least two reflectors are provided; and,

[0027] In the following description, numerous specific details are set forth for illustrative purposes and to provide a thorough understanding of one or more embodiments. However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

Figure 2 The side view structure of the positioning system for the four main vehicles in coke oven production according to an embodiment of the present invention is shown. Figure 3 The diagram shows a top view of the positioning system for the four main production vehicles in a coke oven according to an embodiment of the present invention. Figure 4 A partially enlarged structure of the movable support provided according to an embodiment of the present invention is shown. Figure 5 A top view of the fixing plate provided according to an embodiment of the present invention is shown.

[0030] Combination Figures 1 to 5 As can be seen, the coke oven production four-car positioning system provided by this utility model includes a laser rangefinder 4 and a reflector for positioning the vehicle to be positioned. The laser rangefinder 4 and the reflector are adapted to each other. The laser rangefinder 4 is connected to the end of the coke oven through a movable bracket 6. The laser rangefinder 4 is angled through the movable bracket 6. The reflector is connected to the main beam of the car on the vehicle to be positioned through a movable connecting assembly. The reflector is finely adjusted in position through the movable connecting assembly.

[0031] It should be noted that for the four-wheeled vehicles (i.e., the vehicles to be located), the main beam of the four-wheeled vehicles vibrates less during the vehicle's movement. Therefore, placing the reflector on the main beam of the four-wheeled vehicles will not cause the reflector's movement amplitude and frequency to be too large during the measurement process, thus preventing measurement failure.

[0032] In the actual measurement process, the laser rangefinder 4 emits a laser towards the reflector. After the laser is reflected by the reflector, it is sent back to the laser rangefinder 4. The laser rangefinder 4 recovers the reflected laser and calculates the distance and angle between itself and the reflector based on the recovered reflected laser. The position of the vehicle to be located can be determined by the distance and angle between the laser rangefinder 4 and the reflector.

[0033] It should be noted that although the elevation angle of the laser rangefinder is adjustable, the preferred elevation angle is zero degrees, meaning that the laser emitted by the laser rangefinder is horizontal. This design allows the position of the positioning vehicle to be determined without using the elevation angle of the laser rangefinder, thereby further improving the practicality of the entire device.

[0034] In a preferred embodiment of this invention, two laser rangefinders 4 can be provided; and the two laser rangefinders 4 are respectively installed on the ends of both sides of the coke oven. It should be noted that the coke oven production four-car positioning system provided by this invention only requires one laser rangefinder 4 to complete the positioning of the vehicle to be positioned. Installing laser rangefinders 4 on both sides of the coke oven can further improve the reliability of this positioning method. Specifically, when the four-car (i.e., a certain vehicle to be positioned) is far from the laser rangefinder 4, the accuracy of a single laser rangefinder 4 decreases during the ranging process. If rangefinders are installed at both ends of the coke oven, when the four-car is far from one laser rangefinder 4, it will be relatively close to the other laser rangefinder 4. Positioning the four-car by the laser rangefinder 4 closer to it can ensure the measurement accuracy of the coke oven production four-car positioning system provided by this invention. Furthermore, the two laser rangefinders 4 can also mutually correct their positions, avoiding serious production accidents caused by incorrect positioning of the four-car when one laser rangefinder 4 malfunctions (such as reduced accuracy due to damage).

[0035] In a specific embodiment of this utility model, in order to achieve angle adjustment of the laser rangefinder 4 by the movable bracket 6, the movable bracket 6 may include an upper support plate 61 and a lower support plate 62. The upper support plate 61 and the lower support plate 62 are hinged by a pivot 64, and the laser rangefinder 4 is fixed on the upper support plate 61. Furthermore, the upper support plate 61 has a positive V-shaped structure, and the lower support plate 62 has an inverted V-shaped structure. The side of the upper support plate 61 away from the laser rangefinder 4 is hinged to the middle of the lower support plate 62.

[0036] In actual operation, since the upper support plate 61 and the lower support plate 62 are hinged, the tilt angle (i.e., elevation angle) of the laser rangefinder 4 in the vertical direction can be adjusted by rotating the upper support plate 61. Specifically, to position the upper support plate 61, a positioning waist hole 63 (arc-shaped hole) can be opened on the upper support plate 61, and a positioning hole can be opened on the lower support plate 62. In actual operation, when the upper support plate 61 is adjusted to the preset position, a positioning bolt (not shown in the figure) can be used to lock the position of the upper support plate 61 and the lower support plate 62 by passing through the positioning waist hole 63 and the positioning hole in sequence, thereby locking the elevation angle of the laser rangefinder 4.

[0037] Furthermore, to enable horizontal angle adjustment of the laser rangefinder sensor 4, the movable bracket 6 may also include a fixed plate 65 fixed to the end, on which a turntable 66 is mounted. The lower support plate 62 is rotatably connected to the fixed plate 65 via the turntable 66. In actual operation, the turntable 66 can be rotated to adjust the horizontal angle of the laser rangefinder sensor 4. When the horizontal angle of the laser rangefinder sensor 4 reaches a preset angle, the turntable 66 is locked in position by a latch or other components (not shown in the figure).

[0038] It should be noted that when the turntable 66 rotates to the preset position, there are many existing solutions on how to lock the position of the turntable 66 by means of buckles and other components. This utility model only uses the locking function of buckles and other components, so its specific working principle will not be described in detail.

[0039] In another specific embodiment of this utility model, in order to achieve fine adjustment of the position of the reflector by the movable connecting component, the movable connecting component may include a vertical slide rail 8, on which a first slider is slidably connected, and the reflector is connected to the first slider; and the movable connecting component also includes a transverse slide rail 9 fixed on the vehicle to be positioned, with a second slider fixed at the end of the vertical slide rail 8, and the second slider is slidably connected to the transverse slide rail 9.

[0040] In actual operation, when the reflector needs to be adjusted vertically, the reflector can be moved vertically along with the first slider on the vertical slide rail 8, thereby achieving the vertical position adjustment of the reflector; when the reflector needs to be adjusted horizontally, the reflector can be moved horizontally along with the second slider 7 on the horizontal slide rail 9, thereby achieving the horizontal position adjustment of the reflector.

[0041] It should be noted that in the coke oven production workshop, the vehicles to be positioned are divided into four types: the push car, the coke quenching car, the coal charging car, and the coke quenching car. Each vehicle needs to be positioned. To achieve positioning of each vehicle, multiple reflectors are usually required (at least two). Furthermore, the movable connecting components of each reflector are connected to the corresponding vehicle to be positioned. For example, four reflectors can be set up: the first reflector 5 can be set on the first operating car 10 (such as the push car), the second reflector 12 can be set on the second operating car 11 (such as the coke quenching car), the third reflector (not shown in the figure) can be set on the third operating car (such as the coal charging car, not shown in the figure), and the fourth reflector (not shown in the figure) can be set on the fourth operating car (such as the coke quenching car, not shown in the figure). Finally, positioning is performed on the corresponding operating car by using the corresponding reflector in conjunction with the nearest laser rangefinder.

[0042] In another specific embodiment of this utility model, in order to enable the operation and maintenance of the laser rangefinder sensor 4, an operating platform (not shown in the figure) can be set below the laser rangefinder sensor 4, and a protective railing 3 can be set around the operating platform to ensure the safety of the staff on the operating platform; in addition, a ladder 2 can be set below the operating platform, the ladder 2 is connected to the ground, and the staff can climb from the ground 1 to the operating platform through the ladder 2 to operate and maintain the laser rangefinder sensor 4.

[0043] As can be seen from the above specific embodiments, the positioning system for the four main production vehicles in a coke oven provided by this utility model has at least the following advantages:

[0044] 1. The laser rangefinder is placed on the coke oven and the reflector is placed on the vehicle to be positioned. The laser emitted by the laser rangefinder hits the reflector, and the reflected laser received by the laser rangefinder completes the positioning of the vehicle.

[0045] 2. By setting the movable connection component, the horizontal and vertical positions of the reflector can be finely adjusted, thereby ensuring that the reflector is directly facing the laser emitted by the laser rangefinder.

[0046] 3. By setting up a movable bracket, the horizontal and vertical angles of the laser rangefinder can be adjusted, thereby ensuring that the laser emitted by the laser rangefinder is directly facing the reflector.

[0047] As per the above reference Figures 1 to 5 The positioning system for the four main coke oven production vehicles according to this utility model is described by way of example. However, those skilled in the art should understand that various modifications can be made to the positioning system for the four main coke oven production vehicles proposed in this utility model without departing from the scope of this utility model. Therefore, the scope of protection of this utility model should be determined by the contents of the appended claims.
