Description

Technical Field

[0001] This invention relates to the field of crushers, and more particularly to a measuring tool for the discharge port of a hydraulic gyratory crusher and its usage method. Background Technology

[0002] To ensure the required discharge opening diameter during normal production, the height of the moving cone in a hydraulic gyratory crusher needs to be adjusted before production. Currently, the discharge opening size is mostly determined through direct and indirect methods. Direct detection involves placing lead balls, lead blocks, or lead columns into the unloaded crusher and measuring the size of the crushed balls, blocks, or columns discharged from the crusher to determine the discharge opening size. This method is cumbersome. Indirect detection involves measuring the height of the moving cone to indicate the discharge opening size. However, the discharge opening size obtained through indirect detection is a theoretical size, and when the liners on the moving and fixed cones wear, the discharge opening size obtained by this method becomes inaccurate.

[0003] Chinese Patent CN102944155A discloses a measuring tool and method for using the discharge port of a hydraulic gyratory crusher. The measuring tool is characterized by including a measuring sphere, a rope lug located on the upper part of the measuring sphere, and a measuring rope connected to the rope lug. It has a simple structure, is easy to operate, and can achieve real-time measurement of the discharge port of a hydraulic gyratory crusher.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: Since the moving cone is in a gyratory motion, the distance between it and the inner wall of the bottom of the fixed cone is not always equal. It is difficult to ensure that other parts of the discharge opening are of the appropriate size by having the ball pass through exactly one position, because the ball can pass through different positions in different ways. Moreover, the method of having the ball pass through exactly one position can only draw qualitative conclusions and roughly adjust the height of the moving cone, and cannot obtain more accurate discharge opening size data. Summary of the Invention

[0024] Example 1

[0025] like Figure 1 As shown, the present invention proposes a measuring tool for the discharge port of a hydraulic gyratory crusher, including a fixed cone 1 and a moving cone 2. The outer wall of the fixed cone 1 is provided with multiple sets of reinforcing plates 3, and the top of the fixed cone 1 is provided with a crossbeam 4. It also includes a measuring component, which includes a support mechanism, a support plate 12, a rotating joint and a box a22. The support mechanism is detachably connected to the top of the fixed cone 1.

[0026] like Figure 2-3 As shown, two sets of support plates 12 are provided on the support mechanism. Support rods are rotatably provided on the two sets of support plates 12. A winding wheel 13 is provided on the support rod. Locking bolts b14 that restrict the rotation of the winding wheel 13 are provided on the support plates 12. A rocker handle 15 is provided at the end of the support rod. Multiple sets of rotating joints are provided. The multiple sets of rotating joints are connected end to end. The multiple sets of rotating joints form a strip-shaped support body in the vertical state. The strip-shaped support body has bending and torsional resistance. The topmost rotating joint passes through the support structure and is wound around the winding wheel 13.

[0027] like Figure 6 As shown, the box body a22 is located at the bottom of the rotating joint at the bottom. Distance detection sensors a23 and b24 are respectively installed on the two sides of the box body a22 facing the inner wall liner of the fixed cone 1 and facing the outer wall liner of the moving cone 2. A control system is installed on the support mechanism, and the control system is connected to the distance detection sensors a23 and b24 for data transmission.

[0028] Working principle: Connect the support mechanism to the top edge of the fixed cone 1, and then release the rotating joint by rotating the take-up wheel 13. The rotating joint forms a strip-shaped support with bending resistance in the vertical state. The strip-shaped support is in a vertical state. Then adjust the lateral position of the support mechanism so that the box a22 is located between the bottom of the moving cone 2 and the bottom of the fixed cone 1, and the distance detection sensor a23 is close to the inner wall liner of the fixed cone 1. Then rotate the take-up wheel 13 to make the box a22 move downward continuously. Observe the value of the distance detection sensor a23 through the control system. The value changes from large to small and then from small to large. Find the turning point, stop rotating the take-up wheel 13 and lock it with the locking bolt b14. At this time, the sum of the values ​​of the distance detection sensor a23 and the distance detection sensor b24 plus the distance between their measuring ends is the discharge port size. Then start the hydraulic gyratory crusher for no-load test run. The speed of the moving cone 2 does not exceed 15 r / min. Observe the discharge port size measured at different positions of the moving cone 2 through the control system.

[0029] In this embodiment, a strip-shaped support with certain bending resistance is formed by extending the rotating joint. The distance detection sensor a23 and distance detection sensor b24 are lowered to the measurement position, which can accurately measure the size of the discharge port. Combined with the low-speed no-load test run of the crusher, multiple sets of data can be obtained quickly, which can intuitively reflect the size of the discharge port when the moving cone 2 is located at different positions. It is convenient to use, and the measurement data is numerous and accurate. After use, the rotating joint can be wound up by the winding wheel 13 to reduce the size and facilitate storage.

[0030] Example 2

[0031] like Figure 2-4 As shown, the present invention proposes a measuring tool for the discharge port of a hydraulic gyratory crusher. Compared with Embodiment 1, the support mechanism includes an arc-shaped plate 5, fixing bolts 6, a flat plate 7, a sliding plate 9, and locking bolts a10. The inner peripheral wall of the arc-shaped plate 5 is fitted with the outer peripheral wall of the top of the fixed cone 1. The arc-shaped plate 5 and the reinforcing plate 3 are detachably connected. Specifically, the reinforcing plate 3 has multiple sets of threaded holes arranged side by side on its top. The arc-shaped plate 5 and the reinforcing plate 3 are connected by multiple sets of fixing bolts 6. The flat plate 7 is horizontally set on the top of the arc-shaped plate 5. The flat plate 7 has a horizontally arranged clearance groove 11 for the rotating joint to pass through. The sliding plate 9 is slidably set on the flat plate 7. Specifically, the sliding connection method is as follows: the flat plate 7 has multiple sets of slide rails 8 arranged horizontally. The bottom of the sliding plate 9 has multiple sets of slide grooves arranged horizontally. The slide rails 8 are inserted into the slide grooves. The sliding plate 9 has multiple sets of threaded holes. The locking bolts a10 are engaged with the threaded holes. The bottom of the locking bolts a10 is in contact with the top of the flat plate 7.

[0032] In this embodiment, the arc plate 5 is closely attached to the outer peripheral wall of the top of the fixed cone 1 to ensure concentricity, so that the detection directions of the distance detection sensor a23 and the distance detection sensor b24 are in the diameter direction of the crusher. After the arc plate 5 is fixed by multiple sets of fixing bolts 6, the entire support mechanism is fixed, and the operation is simple and convenient.

[0033] Example 3

[0034] like Figure 5 As shown, the present invention proposes a measuring tool for the discharge port of a hydraulic gyratory crusher. Compared with Embodiment 1, the rotating joint includes a vertical plate 16 and a raised plate 17.

The raised plate 17 is provided at the top of the vertical plate 16 and is inserted into the strip groove 18 of another set of rotating joints. A rotating shaft 19 is provided on the raised plate 17 and is rotatably connected to the wall of the strip groove 18. A magnet b21 is provided on the raised plate 17, and the magnet b21 and the magnet a20 are magnetically attracted to each other.

[0035] In this embodiment, due to the magnetic attraction between magnet b21 and magnet a20, multiple sets of rotating joints are in a vertical state and can maintain a certain rigidity. They can maintain a stable vertical state without external force, thereby ensuring the accuracy of distance detection. In addition, multiple sets of rotating joints can be rotated and wound around the winding wheel 13 for easy storage.

[0037] like Figure 3 and Figure 6 As shown, the present invention proposes a hydraulic gyratory crusher discharge port measuring tool. Compared with Embodiment 1, the control system includes a wire sleeve 25, a housing b28, a controller 30, and an operation panel 31. The housing b28 is mounted on a support mechanism, with a cover plate 32 rotatably mounted on the top of the housing b28. A partition 29 is horizontally mounted on the inner wall of the housing b28, and a power supply is mounted on the inner wall of the bottom of the housing b28, located below the partition 29. The controller 30 is mounted on the outer wall of the housing b28, and the operation panel 31 is mounted on the support mechanism. The controller 30 is electrically connected to the operation panel 31 and to the power supply. A data transmission line 26 and a power supply line 27 are installed inside the wire sleeve 25. Two sets of wire sleeves are installed. One end of the data transmission line 26 is connected to the distance detection sensor a23 or the distance detection sensor b24, and the other end is connected to the controller 30. One end of the power supply line 27 is connected to the distance detection sensor a23 or the distance detection sensor b24, and the other end is connected to the power supply.

[0038] In this embodiment, distance detection sensors a23 and b24 are powered by power cord 27 and power supply. The detected distance values ​​are transmitted to the controller via data transmission line 26 and displayed on the operation panel 31 for easy viewing. The displayed values ​​include the detection value A of distance detection sensor a23, the detection value B of distance detection sensor b24, the distance C between the two detection ends, and the size D of the discharge port, where D = A + B + C. The distance values ​​between the moving cone 2 and the fixed cone 1 can be obtained through a no-load test run.
