Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor correction technology, and in particular to a passive electric upper correction device. Background Technology
[0002] Belt conveyors are essential equipment for transporting bulk materials. They consist of a conveyor belt of a certain width that forms a closed loop, multiple sets of upper and lower idlers for supporting and positioning the conveyor belt, a drive roller, a drive unit, and a support frame. Currently, during the transportation of coal, the uneven distribution of coal on the conveyor belt causes it to deviate during operation. Prolonged deviation will wear down the belt surface, eventually leading to belt breakage. The current solution is to manually adjust the relative positions of the idlers along the line. However, the long conveying distances in mines and the difficulty of maintenance not only increase the labor intensity of workers but also pose significant safety hazards. Therefore, a passive electric upper deviation correction device has been designed to solve these problems. Utility Model Content
[0003] To address the shortcomings of existing conveyor belt alignment technologies, the purpose of this invention is to provide a passive electric upper alignment device with advantages such as automatic alignment and no need for external power supply.
[0004] To achieve the above objectives, the present invention employs the following technical solution: a passive electric upper correction device, comprising a positioning base, a roller frame, a horizontal roller, an inclined roller, a storage battery, a controller, a deflection detection component, an electric lead screw, and a power generation component. The positioning base has a roller frame rotatably connected to its center. Deflection detection components are provided on both sides of the front end of the positioning base. The roller frame has a horizontal leg, an inclined leg, a hinge rod, and a rotating shaft. A rotating shaft for rotatably connecting the bottom of the horizontal leg to the positioning base is provided. Inclined legs are symmetrically arranged on both sides of the horizontal leg. A horizontal roller is rotatably connected to the top of the horizontal leg. An inclined roller is rotatably connected to the top of the inclined leg. The hinge rod is vertically arranged at the front end of the horizontal leg. One end of the electric lead screw is hinged to the hinge rod, and the other end of the electric lead screw is hinged to the positioning base. A power generation component providing power is provided at the front end of the positioning base. A storage battery storing power from the power generation component is provided on one side of the positioning base. A controller for controlling the extension and retraction of the electric lead screw is provided on the other side of the positioning base.
[0005] Preferably, the deflection detection assembly includes a contact shaft, a deflection bracket, an angle sensor, and a column. The column is disposed on both sides of the front end of the positioning base. An angle sensor is fixedly connected to the top of the column. The angle sensor receiving shaft is fixedly connected to the deflection bracket. The top of the deflection bracket is rotatably connected to the contact shaft, which is used to abut against the edge of the conveyor belt.
[0006] Preferably, when the contact shaft in the deflection detection assembly is deflected by the conveyor belt, the controller sends a signal to start the electric screw to drive the idler frame to rotate;
[0007] Preferably, the power generation component includes a generator, a friction shaft, and an extension bracket. The friction shaft is fixed to the front end of the positioning base via the extension bracket. The generator is fixed to the outside of the extension bracket.

[0008] Preferably, the end face of the positioning base also has a protective plate to protect the electric lead screw;
[0009] The beneficial effects of this utility model are: 1. The deflection detection components on both sides of the roller frame detect the conveyor belt deviation. After the deflection detection components detect the conveyor belt deviation, the controller starts the electric screw, which drives the roller frame to rotate, thereby achieving the purpose of automatic deviation correction; 2. The conveyor belt drives the power generation component to generate electricity, and the power of the power generation component is stored in the battery, thereby achieving the effect of not needing external power supply.

[0018] Please see Figures 1 to 5 The embodiments of this utility model include:
[0019] A passive electric upper correction device includes a positioning base 1, a roller frame 2, a horizontal roller 3, an inclined roller 4, a battery 5, a controller 6, a deflection detection component 7, an electric lead screw 8, and a power generation component 9. The positioning base 1 has the roller frame 2 rotatably connected to its center. Deflection detection components 7 are provided on both sides of the front end of the positioning base 1. The roller frame 2 has a horizontal leg 21, an inclined leg 22, a hinge rod 23, and a rotating shaft 24. The bottom of the horizontal leg 21 has a rotating shaft 24 for rotatably connecting with the positioning base 1. The horizontal leg 21 has symmetrically arranged... The device has an inclined limb 22, a horizontal roller 3 rotatably connected to the top of the horizontal limb 21, an inclined roller 4 rotatably connected to the top of the inclined limb 22, a hinge rod 23 vertically disposed at the front end of the horizontal limb 21, one end of the electric screw 8 is hinged to the hinge rod 23, the other end of the electric screw 8 is hinged to the positioning base 1, the front end of the positioning base 1 is provided with a power generation component 9 that provides power, one side of the positioning base 1 is provided with a battery 5 that stores the power of the power generation component 9, and the other side of the positioning base 1 is provided with a controller 6 for controlling the extension and retraction of the electric screw 8.
[0020] The deflection detection assembly 7 includes a contact shaft 71, a deflection bracket 72, an angle sensor 73, and a column 74. The column 74 is disposed on both sides of the front end of the positioning base 1. An angle sensor 73 is fixedly connected to the top of the column 74. The receiving shaft of the angle sensor 73 is fixedly connected to the deflection bracket 72. The top of the deflection bracket 72 is rotatably connected to the contact shaft 71. The contact shaft 71 is used to abut against the edge of the conveyor belt.
[0021] When the contact shaft 71 in the deflection detection assembly is deflected by the conveyor belt, the controller 6 sends a signal to start the electric screw 8 to drive the roller frame 2 to rotate.
[0022] The power generation component 9 includes a generator 91, a friction shaft 92, and an extension bracket 93. The friction shaft 92 is fixed to the front end of the positioning base 1 through the extension bracket 93. The generator 91 is fixed to the outside of the extension bracket 93. The input shaft of the generator 91 passes through the extension bracket 93 and is fixedly connected to the friction shaft 92.

[0023] The end face of the positioning base 1 also has a protective plate 11 to protect the electric lead screw 8;
[0024] With the above settings, its specific working principle in actual operation is as follows:
[0025] When the conveyor belt is running normally, the conveyor belt is in contact with the friction shaft 92, which causes the friction shaft 92 to rotate during operation. The rotating friction shaft 92 drives the generator 91 to generate electricity. The electrical energy generated by the generator 91 is stored in the battery 5. When the battery 5 is fully charged, the controller 6 disconnects the electrical connection between the generator 91 and the battery 5.
[0026] When the conveyor belt deviates to one side, the edge of the conveyor belt touches the contact shaft 71 in the deflection detection component, thereby squeezing the contact shaft 71 to deflect outward. During the deflection process, the contact shaft 71 drives the angle sensor 73 to rotate through the deflection bracket 72. After receiving the signal, the angle sensor 73 transmits it to the controller 6. After receiving the signal, the controller 6 starts the electric screw 8 to drive the roller frame 2 to rotate, so that the inclined roller 4 in the roller frame 2 that is close to the side of the squeezed contact shaft 71 moves closer to it, thereby performing automatic correction.
