Technical Field

[0001] This utility model relates to the technical field of adjustable gantry crane positioning frames, and in particular to an adjustable gantry crane positioning frame. Background Technology

[0002] In the existing technology, gantry cranes are equipped with fixed positioning frames on both sides to limit the position of containers so that they can be placed at intervals. However, in order to reduce costs and improve efficiency, it is necessary to design an adjustable gantry crane positioning frame that is suitable for various container placement methods. Utility Model Content

[0003] Therefore, it is necessary to provide an adjustable gantry crane positioning frame to address the aforementioned technical problems of limited applicability and low efficiency.

[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] Please see Figures 1 to 3 This application provides an adjustable gantry crane positioning frame, including a crane 1. The top of the crane 1 is connected to the gantry crane, thereby enabling the crane 1 to move, rotate, and clamp. A mounting frame 1 2 and a mounting frame 2 3 are fixedly installed on both sides of the crane 1. A positioning frame 1 4 is fixedly installed on the mounting frame 1 2. A positioning frame 2 6 is rotatably installed on the mounting frame 2 3 via a pin 5. An upper positioning groove 7 and a lower positioning groove 8 are provided on the mounting frame 2 3. A mating groove 9 is provided on the positioning frame 2 6. A fixing pin 10 is inserted into the upper positioning groove 7 or the lower positioning groove 8.

[0021] In this embodiment, when the containers are arranged in a typical spaced-out configuration, the positioning frame 2 6 can be rotated downwards around the pin 5. After rotation, the mating groove 9 on the positioning frame 2 6 coincides with the lower positioning groove 8 on the mounting frame 2 3. Thus, the fixing pin 10 can be inserted into the mating groove 9 and the lower positioning groove 8, which achieves the fixing effect of the positioning frame 2 6. As a result, the positioning frame 1 4 at the mounting frame 1 2 cooperates with the positioning frame 2 6 to arrange the containers at intervals. The interval between the containers is the width of the positioning frame 1 4 and the positioning frame 2 6. When the cargo inside the container is small or light, in order to reduce costs, it is necessary to place them densely or multiple containers in a row. In this case, the positioning frame 2 6 is rotated upward so that the mating groove 9 coincides with the upper positioning groove 7, and then the fixing pin 10 is inserted into it, so that the positioning frame 2 6 can be stored. The positioning frame 1 4 can be positioned outside the container stack by rotating the crane 1, so that when placing containers, the positioning frame 1 4 will not collide with the already placed containers and thus create gaps. Since the crane 1 requires the crane operator and the ground command to work together, the adjustment of the positioning frame 2 6 can be completed by the ground command.

[0022] In some embodiments, to facilitate the fixing of the fixing pin 10, a pin 11 is movably inserted into the fixing pin 10. A limiting wire 12 is hinged to one end of the pin 11, and the side of the limiting wire 12 away from the hinged end is engaged with the other end of the pin 11. A groove is provided on the pin 11. After the fixing pin 10 is inserted and fixed, the pin 11 can be inserted into the fixing pin 10 again to limit it and prevent the fixing pin 10 from falling off. After limiting it, the limiting wire 12 is hinged and deflected so that the other end of the limiting wire 12 can be engaged in the groove on the pin 11, thereby preventing the pin 11 from falling off.

[0023] In some embodiments, to further improve production efficiency, a visual signal sensor 13 is fixedly mounted on the mounting bracket 2. The visual signal sensor 13 can be used in conjunction with the crane operator for observation.

[0024] In some embodiments, to facilitate the installation of the positioning frame 4, the positioning frame 4 is fixedly installed on the mounting frame 2 by two pins 14.

[0025] In some embodiments, to further improve the cost reduction and efficiency, a rotating rod 15 is rotatably mounted on the mounting bracket 2 3 via a fixed shaft. A pull rope displacement sensor 16 is fixedly mounted on the mounting bracket 2 3. A limit groove 17 is formed on the rotating rod 15. The pull rope at the output end of the pull rope displacement sensor 16 passes through the limit groove 17 and is fixedly mounted on the rotating rod 15. The limit groove 17 is located between the pull rope mounting end and the fixed shaft. Both the visual signal sensor 13 and the pull rope displacement sensor 16 are connected to an external signal processor. After the positioning frame 2 6 is lowered, the fixing pin 10 is not inserted to fix it. When clamping the container, the visual signal sensor 13 at the positioning frame 1 4 can observe the situation at the positioning frame 1 4. After the positioning frame 2 6 is lowered, if it is offset to a certain extent, the chamfer at the top will collide with the container and deflect to a certain extent. When it deflects, it will squeeze the rotating rod 15 and make it rotate around the fixed axis. The pull rope at the output end of the pull rope displacement sensor 16 is installed on the rotating rod 15 after passing through the positioning groove 17. Therefore, the pull rope can be stretched by the deflected rotating rod 15, so the displacement signal sensor 16 can issue a warning signal. Thus, the visual signal sensor 13 and the pull rope displacement sensor 16 work together to improve the clamping speed and achieve the effect of reducing costs and increasing efficiency.

[0026] In some embodiments, to facilitate the protection of the pull rope of the displacement signal sensor 16, two protective shafts 18 are rotatably installed in the limiting groove 17, and the pull rope passes between the two protective shafts 18.

[0027] In some embodiments, to facilitate the reset of the rotating rod 15 after deflection, a spring 19 is fixedly installed on the mounting bracket 2 3, and the output end of the spring 19 is fixedly connected to the rotating rod 15.

[0028] In some embodiments, to facilitate the operator's control of the deflection of the rotating rod 15 so that the positioning frame 2 6 can rotate up and down, a handle 20 is fixedly installed on the outer end of the rotating rod 15.

[0029] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
