Description

Technical Field

[0001] This utility model relates to the field of vibrator testing technology, and more specifically, to a mining vibrator testing platform. Background Technology

[0002] Mining vibrators are vibration devices specifically designed for use in mining and mineral processing. They are widely used in processes such as vibrating screening, vibrating feeding, and vibrating conveying to improve production efficiency and product quality. Simulation testing of vibrators helps researchers and engineers verify their design, performance, and reliability. However, the market currently offers a wide variety of vibrating screen models and sizes, and many existing testing platforms typically only test basic performance parameters such as vibration frequency and load capacity. These platforms often fail to simulate the specific effects of vibrators installed in different locations, necessitating frequent platform changes. This not only reduces testing efficiency but also increases testing errors after relocation. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a test platform for a mining exciter, so as to solve the problem that in the process of testing exciters, frequent changes of different test platforms are required, which leads to reduced testing efficiency and increased errors.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mining vibrator test platform, comprising...

[0005] The base plate has spring frames fixedly installed on the upper surface of each of the four corners. A screening mechanism is fixedly installed on the top of each of the four spring frames. A collection bin is fixedly installed on the lower surface of the middle part of the screening mechanism. A displacement component is provided at the bottom of the collection bin.

[0006] The displacement assembly includes a frame, a first moving mechanism, and a second moving mechanism. Two frames are arranged parallel to each other at the bottom edge of the collection chamber. The tops of both frames are fixedly installed to the bottom of the collection chamber. The outer surfaces of both ends of the first moving mechanism are slidably installed with the inner surfaces of the frame. A movable block is movably installed in the middle of the first moving mechanism. Two eccentric plates are fixedly sleeved at the bottom ends of the movable block by a shaft, and the shaft is rotatably installed with the inner surface of the bottom of the movable block. The second moving mechanism is located on the side of one of the frames.

[0007] It also includes a lifting assembly and a drive motor. The outer surface of the top of the lifting assembly is fixedly installed with the outer surface of the drive motor, and the output end of the drive motor is detachably installed with the shaft sleeved inside the eccentric plate.

[0008] The moving mechanism includes an I-shaped horizontal plate and a reciprocating lead screw. The inner surfaces at both ends of the I-shaped horizontal plate are rotatably sleeved with the outer surfaces at both ends of the reciprocating lead screw. A motor is fixedly installed on the side of the I-shaped horizontal plate. The output end of the motor is fixedly sleeved with the inner surface of the end of the reciprocating lead screw. The outer surface of the reciprocating lead screw is threadedly connected to the inner surface of the middle part of the movable block. The inner surface of the middle part of the I-shaped horizontal plate is slidably installed with the outer surface of the top of the movable block.

[0009] The second moving mechanism includes a U-shaped frame, a serrated plate, and a U-shaped plate. The sides of both ends of the U-shaped frame are fixedly installed with the side of a frame. The serrated plate is fixedly installed on the side of the U-shaped frame near the first moving mechanism. The end of the U-shaped plate is fixedly installed with the surface of the end of the serrated plate away from the first motor. The second motor is fixedly installed on the top of the U-shaped plate. A gear is fixedly sleeved on the output end of the second motor, and the gear meshes with the serrated plate.

[0010] The lifting assembly includes a support column, a movable column, and an electric push rod. The inner surface of the middle part of the support column is movably connected to the outer surface of the bottom end of the movable column. Two symmetrically arranged fixing plates are fixedly installed in the middle of the two sides of the bottom end of the support column, and two symmetrically arranged fixing plates are also fixedly installed in the middle of the two sides of the top end of the movable column. The upper and lower ends of the electric push rod are respectively fixedly installed on the surfaces of the two vertically parallel fixing plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In the above scheme, by setting up a displacement component, the operator controls the start of motor one, and the reciprocating screw connected to the output end of motor one rotates along the inner walls of both ends of the I-shaped horizontal plate. The movable block connected to it slides against the inner wall of the middle of the I-shaped horizontal plate, driving the eccentric plate at the bottom of the movable block and the shaft to adjust the position of the collection bin along its length. At the same time, motor two can be started, so that the gear fixedly connected to the output end of motor two rotates in the middle of the I-shaped horizontal plate away from motor one, moves along the surface of the meshing sawtooth plate, and pulls the U-shaped plate to slide along the outer edge of the U-shaped frame. This drives the connected moving mechanism one and its movable block, eccentric plate and other structures to adjust the position of the collection bin along its width. Then, the shaft connected to the eccentric plate is connected to the output end of the drive motor, so that the vibrator composed of the drive motor, movable block, eccentric plate and other structures can be tested. The displacement component can be used to adjust its position at the bottom of the collection bin, and different screening effects can be achieved through the screening mechanism to achieve different test results, improve test efficiency, and avoid test errors after movement.

[0013] In the above scheme, by setting up a lifting assembly, when using different models of eccentric plates, the height of the fixed shaft inside the eccentric plate is different. The operator can control the extension or retraction of the electric push rod to drive the movable column connected through the fixed plate to slide up and down along the inside of the support column, thereby adjusting the height of the drive motor installed at the top. This allows the height of the lifting assembly to be adjusted according to the height of the eccentric plate, so that the output shaft of the drive motor can be connected to the shaft connected to the eccentric plate. Thus, during the test, by connecting a constant input source with a changing eccentric plate, the effect of controlling variables is achieved, thereby improving the test results.

[0021] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a test platform for a mining vibrator, including...

[0022] The base plate 1 has spring frames 2 fixedly installed on the upper surface of the four corners of the base plate 1.

[0023] The displacement assembly 9 includes a frame 90, a first moving mechanism 91, and a second moving mechanism 92. Two frames 90 are arranged parallel to each other at the bottom edge of the collection chamber 4. The tops of the two frames 90 are fixedly installed to the bottom of the collection chamber 4. The outer surfaces of both ends of the first moving mechanism 91 are slidably installed with the inner surfaces of the frames 90. A movable block 7 is movably installed in the middle of the first moving mechanism 91. Two eccentric plates 8 are fixedly sleeved at the bottom ends of the movable block 7 by a shaft, and the shaft is rotatably installed with the inner surface of the bottom of the movable block 7. The second moving mechanism 92 is located on the side of one of the frames 90.

[0024] It also includes a lifting assembly 5 and a drive motor 6. The outer surface of the top of the lifting assembly 5 is fixedly installed on the outer surface of the drive motor 6, and the output end of the drive motor 6 is detachably installed on the shaft sleeved inside the eccentric plate 8.

[0025] The moving mechanism 91 includes an I-shaped horizontal plate 910 and a reciprocating screw 912. The inner surfaces at both ends of the I-shaped horizontal plate 910 are rotatably sleeved with the outer surfaces at both ends of the reciprocating screw 912. A motor 911 is fixedly installed on the side of the I-shaped horizontal plate 910. The output end of the motor 911 is fixedly sleeved with the inner surface at the end of the reciprocating screw 912. The outer surface of the reciprocating screw 912 is threadedly connected to the inner surface of the middle part of the movable block 7. The inner surface of the middle part of the I-shaped horizontal plate 910 is slidably installed with the outer surface of the top of the movable block 7.

[0026] By setting up the I-shaped horizontal plate 910, after adjusting the positions of structures such as the movable block 7 and the eccentric plate 8 using the displacement component 9, the two ends of the I-shaped horizontal plate 910 are further fixed to the surfaces of the frame 90 installed on both sides of the bottom of the collection chamber 4, as well as the top of the movable block 7 and the bottom of the collection chamber 4, with bolts, thereby improving the connection strength and stability.

[0027] The second moving mechanism 92 includes a U-shaped frame 920, a serrated plate 921, and a U-shaped plate 922. The sides of both ends of the U-shaped frame 920 are fixedly installed with the sides of a frame 90. The serrated plate 921 is fixedly installed on the side of the U-shaped frame 920 near the first moving mechanism 91. The end of the U-shaped plate 922 is fixedly installed with the surface of the end of the serrated plate 921 away from the first motor 911. The top of the U-shaped plate 922 is fixedly installed with a second motor 923.

The upper and lower ends of the electric push rod 53 are fixedly installed on the surfaces of the two vertically parallel fixing plates 52 respectively.

[0029] By setting up the lifting assembly 5, when using different models of eccentric plates 8, the height of the fixed shaft inside the eccentric plate 8 is different. The operator can control the extension or retraction of the electric push rod 53 to drive the movable column 51 connected through the fixed plate 52 to slide up and down along the inside of the support column 50, thereby adjusting the height of the drive motor 6 installed at the top. This allows the height of the lifting assembly 5 to be adjusted according to the height of the eccentric plate 8, so that the output shaft of the drive motor 6 can be connected to the shaft connected to the eccentric plate 8. Thus, during the test, by connecting a constant input source with a changing eccentric plate 8, the effect of controlling variables is achieved, thereby improving the test results.

[0030] The working process of this utility model is as follows:

[0031] The operator starts motor 911, causing the reciprocating screw 912, which is connected to the output end of motor 911, to rotate along the inner walls of both ends of the I-shaped horizontal plate 910. The movable block 7, threaded onto the screw, slides against the inner wall of the middle of the I-shaped horizontal plate 910, causing the eccentric plate 8 at the bottom of the movable block 7 and the shaft to adjust their position along the length of the collection chamber 4. Simultaneously, the operator can start motor 923, causing the gear 924, which is fixedly connected to the output end of motor 923, to rotate in the middle of the I-shaped horizontal plate 910 away from the end of motor 911. This gear moves along the surface of the meshing sawtooth plate 921, pulling the U-shaped plate 9... 22 slides along the outer edge of the U-shaped frame 920, driving the connected moving mechanism 91 and its movable block 7, eccentric plate 8 and other structures to adjust their positions in the width direction of the collection chamber 4. Then, the output end of the drive motor 6 is connected to the shaft connected to the eccentric plate 8, so that the vibrator composed of the drive motor 6, movable block 7, eccentric plate 8 and other structures can be tested. The displacement component 9 can be used to adjust its position at the bottom of the collection chamber 4. Different sieving effects are achieved through the sieving mechanism 3, thus improving testing efficiency and avoiding test errors after movement.
