Description

Technical Field

[0001] This application relates to the field of warehouse location measurement technology, and more specifically, to a warehouse location measuring device. Background Technology

[0002] In the cement production industry, storage location measurement is often required in multiple stages. In the cement industry, "storage location" usually refers to the capacity or level of the location where raw materials or finished products are stored, such as clinker storage, fly ash storage, and cement storage, in order to achieve orderly management of cement production and materials.

[0003] Currently, radar and ultrasonic level gauges are commonly used. However, since the transmitting mechanism that generates high-frequency waves needs to be directly aimed at the material, when measuring high-temperature materials, the high-temperature environment will affect the transmitting structure, making it impossible to measure normally.

[0004] In view of this, the present application aims to provide a storage location measuring device to better solve the above-mentioned technical problems. Summary of the Invention

[0006] This application provides a storage location measuring device, including a measuring frame, a winding structure, a contact structure, an encoder, and an electrical control box. The measuring frame is installed on the top of the storage bin to be measured. The winding structure is installed on the measuring frame and connected to the contact structure via a rope, which drives the contact structure to move up and down within the storage bin to contact the material location. The encoder is coaxially installed with the winding structure to rotate synchronously, measuring the number of rotations of the contact structure driven by the winding structure. The electrical control box is installed on the measuring frame and connected to both the winding structure and the encoder.

[0007] Furthermore, the measuring frame is equipped with a fixing clamp for clamping and mounting the material to be measured at the top of the hopper.

[0008] Furthermore, the winding structure is configured as a winch.

[0009] Furthermore, the winch is equipped with a spring return structure, the pulling force of which is less than the weight of the contact structure, so as to tighten the rope.

[0010] Furthermore, the touch structure is configured as a touch ball, and the touch ball is equipped with a proximity sensor, which is connected to the electrical control box.

[0011] Furthermore, a PLC control board is installed inside the electrical control box, and a display screen is provided on the outside of the electrical control box, which is connected to the PLC control board.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0023] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application 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, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] See Figure 1As shown, the storage location measuring device described in this embodiment includes a measuring frame 1, a winding structure 2, a contact structure 3, an encoder 4, and an electrical control box 5. The measuring frame 1 is installed on the top of the storage bin to be measured. The winding structure 2 is installed on the measuring frame 1 and connected to the contact structure 3 via a rope 6, which drives the contact structure 3 to move up and down within the storage bin to contact the material position. The encoder 4 is coaxially installed with the winding structure 2 to rotate synchronously, measuring the number of rotations of the contact structure 3 driven by the winding structure 2. The electrical control box 5 is installed on the measuring frame 1 and connected to both the winding structure 2 and the encoder 4.

[0027] This embodiment has a simple structure and reasonable design. In use, the winding structure 2 is controlled by the electrical control box 5 to drive the contact structure 3 to move up and down to contact the material. The encoder 4 measures the number of rotations to calculate the length of the rope 6 as it descends, thus achieving simple and flexible storage location measurement.

[0028] In some embodiments, the measuring frame 1 is provided with a fixing clip 11 for clamping the top of the hopper to be measured.

[0029] In this embodiment, a fixing clip 11 is provided to facilitate the installation of the measuring frame 1. Specifically, it can be a U-shaped clip, which is fixed by bolts.

[0030] In some embodiments, the winding structure 2 is configured as a winch.

[0031] This embodiment specifically shows that the lifting and lowering of the contact structure 3 is driven by a winch. The winch here can be a commercially available standard model.

[0032] Specifically, see Figure 2 As shown, the winch is equipped with a spring return structure 7. The pulling force of the spring return structure 7 is less than the weight of the contact structure 3, so as to tighten the rope 6.

[0033] In this embodiment, based on the existing winch, a spring reset structure 7 is provided to tighten the rope 6 when the contact structure 3 descends to contact the material, thereby achieving accurate measurement. The spring reset structure 7 here needs to be coaxially installed with the encoder 4 and the winding structure 2. The two ends of the rotating shaft can be directly rotatably connected to the measuring frame 1, and the inlet and outlet through holes of the rope 6 are reserved at the corresponding lower end of the winding structure 2.

[0034] Based on the above embodiments, the touch structure 3 is configured as a touch ball, and the touch ball is provided with a proximity sensor 8, which is connected to the electrical control box 5.

[0035] In this embodiment, a proximity sensor 8 is provided to detect the approaching material in a timely manner and stop the rope 6 from being lowered further. The part that descends based on inertia can be tightened by a coil spring reset structure 7, thereby achieving accurate measurement.

[0036] In some embodiments, a PLC control board is installed inside the electrical control box 5, and a display screen 51 is provided on the outside of the electrical control box 5, the display screen 51 being connected to the PLC control board.

[0037] In this embodiment, a PLC control board is installed inside the electrical control box 5 to control the winding structure 2 and process the data from the encoder 4 for better measurement. The measured material level information can be displayed on the display screen 51 for intuitive viewing.

[0038] In some embodiments, the encoder 4 is configured as an absolute encoder 4.

[0039] In this embodiment, an absolute encoder 4 is specifically used because the rope 6 may become loose during the descent. During the tightening process of the coil spring reset structure 7, the winding structure 2 will reverse. The absolute encoder 4 can achieve accurate counting. It has a simple structure and high measurement accuracy.

[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
