[0002] Many mineral processing plants currently use pre-selection equipment for mineral processing, which typically employs laser sensors to detect the minerals transported by the conveying mechanism. Current pre-selection equipment generally simply and relatively exposedly mounts the laser sensor on a frame above the mineral conveying mechanism. In harsh environments, the detection end of the laser sensor is easily contaminated, affecting its performance and detection accuracy. Frequent disassembly and cleaning maintenance are necessary, which is cumbersome and time-consuming, reducing long-term production efficiency. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a laser sensor adjustment and fixing device.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A laser sensor adjustment and fixing device includes a detection space frame and a sensor mounting box;

[0006] The detection space frame is fixedly connected to the external equipment frame and is located above the mineral conveying mechanism used to transport the mineral to be detected. The upper and lower ends of the detection space frame are open, and the lower end opening of the detection space frame faces the surface of the mineral conveying mechanism.

[0007] The bottom of the sensor mounting box is installed at the upper opening of the detection space frame. The interior of the sensor mounting box is equipped with an adjustment and mounting assembly for mounting the laser sensor. A light-transmitting window is opened on the bottom surface of the sensor mounting box at a position corresponding to the laser sensor, and a transparent window plate is installed at the light-transmitting window.

[0008] The detection space frame includes a frame body, with several side panels installed on the front, back, left, and right sides of the frame body. At least one of the four sides of the frame body has an inspection port, and a door panel is installed at the inspection port of the frame body via hinges. When the frame body, all the side panels, and the door panel are installed, the whole has only two openings, one at the top and one at the bottom, when the door panel is closed. The bottom of the sensor mounting box is also installed at the top of the frame body.

[0009] Several lifting rings are provided on the top of the main frame and on the outside of the sensor mounting box.

[0010] The bottom of the frame body extends to the front and rear sides along the length of the frame body and is provided with fixed ends. The fixed ends are used for the fixed connection between the detection space frame body as a whole and the external equipment frame.

[0011] The top of the sensor mounting box has an opening, and a cover plate is installed at the top opening of the sensor mounting box.

[0012] The sensor mounting housing has an annular mounting edge extending outward from the top opening, and the annular mounting edge is fixedly connected to the cover plate by bolts.

[0013] A sealing ring is provided on the inner circumference of the annular mounting edge.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail.

[0032] A laser sensor adjustment and fixing device, such as Figure 1-6 As shown, this embodiment includes a detection space frame 1 and a sensor mounting box 2.

[0033] The detection space frame 1 is fixedly connected to the external equipment frame and is located above the mineral conveying mechanism used to transport the mineral to be detected. The detection space frame 1 has openings at both the top and bottom, with the lower opening facing the surface of the mineral conveying mechanism.

[0034] The bottom of the sensor mounting box 2 is installed at the upper opening of the detection space frame 1. The interior of the sensor mounting box 2 is equipped with an adjustment and mounting assembly for installing the laser sensor. A light-transmitting window is opened on the bottom surface of the sensor mounting box 2 at a position corresponding to the laser sensor, and a transparent window plate 3 is installed at the light-transmitting window. The laser sensor mentioned in this embodiment is a commercially available product. The laser sensor is placed inside the sensor mounting box 2, which effectively protects the laser sensor and prevents its detection end from being easily contaminated due to direct and relatively exposed exposure to the working environment. This eliminates the need for frequent removal of the laser sensor for cleaning and maintenance. The laser sensor detects minerals on the mineral conveying mechanism through the transparent window plate 3. In this embodiment, the transparent window plate 3 can be made of existing high-transmittance glass, explosion-proof glass, high-temperature resistant glass, etc., depending on the application requirements.

[0035] Specifically, such as Figure 1-3As shown, in this embodiment, the detection space frame 1 includes a frame body 101. Several side panels 102 are installed on the front, back, left, and right sides of the frame body 101. An inspection port is formed on one of the four sides of the frame body 101, and a door panel 103 is installed at the inspection port of the frame body 101 via a hinge 4. In this embodiment, the front-back direction is a horizontal direction parallel to the length direction of the detection space frame 1, and the left-right direction is a horizontal direction perpendicular to the length direction of the detection space frame 1. When the door panel 103 is closed, the overall structure formed by the frame body 101, all side panels 102, and door panel 103 has only two openings, one at the top and one at the bottom. The bottom of the sensor mounting box 2 is also installed at the top of the frame body 101. The internal space of the overall structure formed by the frame body 101, all side panels 102, and door panel 103 can form an effective laser sensor monitoring area and ensure that it is not affected by external ambient light. Each side panel 102 can be installed on the frame body 101 with bolts for easy assembly and disassembly. By using hinges 4 to install a door panel 103 on the frame body 101, it is easy to open, thereby making it simple and convenient to perform maintenance work on the interior of the frame body 101 and to clean the exterior surface of the transparent window panel 3. A handle A14 can be further provided on the door panel 103 to facilitate pulling and opening the door panel 103.

[0036] Specifically, in this embodiment, four lifting rings 104 are evenly provided at the top of the frame body 101 and on the outside of the sensor mounting box 2, which facilitates the overall hoisting and movement of the detection space frame 1. In this embodiment, fixed ends 105 are provided at the bottom of the frame body 101 extending to the front and rear sides along the length of the frame body 101, respectively. The fixed ends 105 are used to fix the detection space frame 1 to the external equipment frame by bolts or other means, which facilitates installation.

[0037] Specifically, in this embodiment, the sensor mounting housing 2 has an opening at its top, and a cover plate 5 is installed at the top opening of the sensor mounting housing 2. All components in the sensor mounting housing 2 are inserted through this top opening, and the cover plate 5 is used to close the top opening of the sensor mounting housing 2. A handle B15 can be further provided on the top surface of the cover plate 5 for easy pulling and opening. An annular mounting edge 201 extends outward from the top opening of the sensor mounting housing 2, and the annular mounting edge 201 is fixedly connected to the cover plate 5 by bolts, facilitating the installation and connection of the cover plate 5. A sealing ring is provided on the inner circumference of the annular mounting edge 201, which effectively ensures the sealing effect after the cover plate 5 is installed, effectively preventing dust and other contaminants from entering the sensor mounting housing 2 and affecting the operation of the laser sensor. The specific setting method of the sealing ring adopts existing technology. Four lifting lugs 202 are evenly provided on the outer surface of the sensor mounting housing 2, excluding the bottom surface, to facilitate the overall lifting and movement of the sensor mounting housing 2.

[0038] Specifically, in this embodiment, an electric heater 6 is installed inside the sensor mounting housing 2 to heat the housing, ensuring it operates normally within a suitable temperature range and is unaffected by low external ambient temperatures. The interior of the sensor mounting housing 2 can also be used to mount other types of sensors, and can be adjusted according to different usage requirements. In this embodiment, the electric heater 6 is a commercially available product, and its installation structure is also existing. The electric heater 6 and the laser sensor are connected to the controller, which itself also uses existing technology. The controller can also be housed within the sensor mounting housing 2, and the housing 2 can be equipped with connectors for connecting internal and external electrical components for easy connection and use.

[0039] Specifically, such as Figure 4-6 As shown, in this embodiment, the adjustment and installation components include a vertical fixing frame group, a crossbeam 7, and a mounting base plate 8. There are two vertical fixing frame groups and two crossbeams 7. Each vertical fixing frame group is used in conjunction with one crossbeam 7, and each vertical fixing frame group has two vertical fixing frames 9.

[0040] Two vertical fixing frames 9 in each group of vertical fixing frames are fixed to two opposite inner side walls of the sensor mounting box 2. Each vertical fixing frame 9 has an elongated hole A 901 parallel to the vertical direction. An adjusting bolt A 10 passes through each elongated hole A 901, and a nut A11 is connected to each adjusting bolt A10. The adjusting bolts A10 on each vertical fixing frame 9 pass through the crossbeam 7 corresponding to that vertical fixing frame 9. By tightening the nut A11 on each adjusting bolt A10, the crossbeam 7 is clamped and fixed to the vertical fixing frame 9. By adjusting the height position of the adjusting bolts A 10 in the elongated hole A 901, the height position of the crossbeam 7 after fixing can be adjusted. In this embodiment, the two crossbeams 7 are located at the same height position and are parallel to each other after fixing.

[0041] Each crossbeam 7 is fitted with two adjusting bolts B12. A mounting base 8 is placed on each of the two crossbeams 7. The mounting base 8 has elongated holes B801 corresponding to the adjusting bolts B12, allowing the bolts to pass through. The length of all elongated holes B801 is parallel to the length of the sensor mounting housing 2. Each adjusting bolt B12 is connected to a nut B13. The mounting base 8, placed on the two crossbeams 7, can be adjusted horizontally along the length of the elongated holes B801. By tightening the nuts B13 on each adjusting bolt B12, the mounting base 8 is clamped and fixed to the two crossbeams 7. The mounting base 8 is used to connect to the laser sensor via screws. The laser sensor is mounted on the underside of the mounting base 8, located between the two crossbeams 7, and corresponding to the position of the transparent window panel 3. Through the aforementioned installation process, the height and horizontal position of the laser sensor can be easily adjusted during installation according to the actual specifications of different laser sensor models, and subsequent fixing is stable and reliable, preventing displacement of the laser sensor.
