Moreover, the coal mine belt conveyor can not only be used in the process of coal production and processing, but also be applicable to the production and processing processes of other minerals. And most of them are equipped with belt flaw detection devices during use.

[0003] However, the installation of the existing flaw detection devices is relatively troublesome.

The utility model has the advantages of being easy to use. During the actual use process, it plays a role in facilitating the installation and detection of the detection equipment, avoiding the situations of high maintenance cost, complex maintenance, and single detection form, saving the maintenance cost and being simple to maintain. And it also avoids the situation that multiple workers are required to cooperate in the installation, which is both time-saving and labor-saving, and reduces the working burden of the user."

[0004] Although the installation direction of the existing coal conveying belt flaw detection device in the prior art achieves the effect of being easy to install, it can only be installed on a vertical wall surface. Usually, the coal conveying belt flaw detection device needs to be installed inside the coal conveying belt support, that is, under the belt, emitting detection light upwards, and the coal conveying belt is in an operating state during work. Therefore, the above installation structure has poor practicability. At the same time, when the existing flaw detection device is installed under the belt, it is easily polluted by coal materials or sewage, which may cause detection errors of the flaw detection device and affect the normal operation of the flaw detection device. Summary of the Utility Model

[0005] In order to overcome the defects existing in the prior art, a coal conveying belt flaw detection device is provided now to solve the problems of poor practicability of the existing coal conveying belt flaw detection device and the lack of self-protection of the flaw detection device.

[0006] To achieve the above object, a coal conveying belt flaw detection device is provided, including: a base, a mounting component, a protection component, and a detection device. The mounting component is hinged to the lower end of the base, the detection device is mounted on the upper end of the base, and the protection component is mounted on the upper side of the detection device. The mounting component includes a motor, and the output shaft end of the motor is connected to a double-threaded screw rod. At the same time, clamping blocks are symmetrically connected to both sides of the double-threaded screw rod. The protection component includes a nylon cloth, and the two sides of the nylon cloth are respectively connected to a first cross bar and a second cross bar, and an electric push rod is connected to the lower end of the first cross bar.

[0007] Further, a first bolt is mounted on the right side wall of the base, a second bolt is mounted near the left edge of the front side of the base, and a clamping groove is opened at the bottom of the base below the second bolt.

[0008] Further, the mounting component includes a bottom plate in contact with the bottom of the base, and two parallel fixing blocks are fixed to the lower side of the bottom plate. At the same time, the double-threaded screw rod is rotatably connected between the fixing blocks, and the motor is mounted outside the fixing blocks.

[0009] Further, a screwing block is screwed on the outside of the double-threaded screw rod, and a connecting block is connected to the outer end of the screwing block. At the same time, the clamping block is connected to the outer end of the connecting block, and a guide rod slidably penetrates through the inside of the connecting block. The guide rod is connected between the two fixing blocks.

[0010] Further, one end of the bottom plate of the mounting component is hinged to a corner on one side of the lower end of the base, and a threaded hole is opened at the outer end of the bottom plate at the hinge. At the same time, the first bolt is in mating connection with the threaded hole.

[0011] Further, a support rod is connected to the lower end of the second cross bar, and the lower end of the support rod is fixed to the upper side edge of the base, and the electric push rod is fixed to the outer wall of the base.

[0012] Further, a pressure sensor is mounted on the upper side of the housing of the detection device, and the pressure sensor is electrically connected to the electric push rod through a microcontroller installed inside the base. Beneficial effects

[0013] 1. By using the motor, double-threaded screw rod, screwing block, and clamping block included in the mounting component, the mounting component can be placed inside the bracket under the coal conveying belt, and the clamping blocks are placed on both sides of the longitudinal beam of the bracket. Then, start the motor to drive the clamping blocks to move closer and clamp the longitudinal beam to complete the installation, which is relatively convenient. If it is to be installed on the wall, first remove the second bolt, then turn the bottom plate to a direction parallel to the outer edge of the base, and then fix the bottom plate with the first bolt. At this time, place the detection device under the belt, then align the clamping blocks with the positioning plate installed on the wall, and then start the motor to clamp the positioning plate with the clamping blocks to complete the fixation, thus realizing two installation methods and increasing the practicability;

[0014] 2. Utilize the support rod, cross bar and nylon cloth included in the protection assembly, so that when sewage or coal falls on the nylon cloth, the nylon cloth is pressed downward and touches the detection end of the pressure sensor. The pressure sensor sends a signal to the electric push rod, so that the electric push rod starts to push the first cross bar upward, thereby propping up one end of the nylon cloth to make it in an inclined state, so that the sewage and coal on the upper side slide down due to their own weight, avoiding the impact on the flaw detection rays generated by the detection device.

DETAILED DESCRIPTION

[0020] Reference Figures 1 to 4 As shown, the utility model provides a coal conveyor belt flaw detection device, including: a base 1, a mounting assembly 2, a protection assembly 3 and a detection device 5, the mounting assembly 2 is hinged at the lower end of the base 1, and the detection device 5 is installed at the upper end of the base 1, and the protection assembly 3 is installed on the upper side of the detection device 5, the mounting assembly 2 includes a motor 21, and the output shaft end of the motor 21 is connected with a double-screw screw 25, and the two sides of the double-screw screw 25 are symmetrically connected with clamping blocks 27, the protection assembly 3 includes a nylon cloth 32, and the two sides of the nylon cloth 32 are respectively connected with a first cross bar 31 and a second cross bar 33, and an electric push rod 35 is connected to the lower end of the first cross bar 31, and a support rod 34 is connected to the lower end of the second cross bar 33, and the lower end of the support rod 34 is fixed at the upper edge of the base 1, and the electric push rod 35 is fixed to the outer wall of the base 1, and a pressure sensor 4 is installed on the upper side of the shell of the detection device 5, and the pressure sensor 4 is electrically connected to the electric push rod 35 through a microcontroller installed inside the base 1.

[0021] In this embodiment, the base 1, the mounting assembly 2, the protection assembly 3, the detection device 5, and the pressure sensor 4 constitute the main structure of the coal conveying belt flaw detection device involved in this application. Among them, the detection device 5 is set as an X-ray flaw detector device, and the rays emitted by it are directed towards the rotating cycle of the coal conveying belt on the lower side of the bracket.

[0022] Specifically, a plastic waterproof film is integrally bonded to the lower side of the nylon cloth 32, which achieves a waterproof effect. At the same time, there is a distance of two to three centimeters between the bottom of the nylon cloth 32 and the pressure sensor 4 in the initial state, and the X-ray can penetrate the nylon cloth 32 and the plastic waterproof film.

[0023] As a preferred implementation method, after the pressure sensor 4 is electrically connected to the electric push rod 35, the impurities on the upper side of the nylon cloth 32 can be immediately overturned and cleaned, and at the same time, large coal materials are prevented from damaging the flaw detector device.

[0024] Such as Figure 1 and Figure 2 As shown in [relevant figures], a first bolt 11 is installed on the right side wall of the base 1, and a second bolt 12 is installed near the left edge of the front side of the base 1. And a clamping groove is opened at the bottom of the base 1 below the second bolt 12. One end of the bottom plate of the mounting assembly 2 is hinged to the lower side corner of one end of the base 1, and a threaded hole is opened at the outer end of the bottom plate at the hinge. And the first bolt 11 is connected to the threaded hole in a matching manner.

[0025] Specifically, a plug-in block with a threaded hole is connected to the end of the bottom plate far from the hinge point. When the plug-in block is inserted into the clamping groove, the bottom plate is flush with the bottom of the base 1 and is fixed by the second bolt 12.

[0026] As a preferred implementation method, by adjusting the rotatable angle of the bottom plate, the device can be made suitable for installation on the wall or the longitudinal beam of the belt support at the same time.

[0027] Such as Figure 3 As shown in [relevant figures], the mounting assembly 2 includes a bottom plate in contact with the bottom of the base 1. And two parallel fixing blocks 22 are fixed to the lower side of the bottom plate. And a double-threaded screw rod 25 is rotatably connected between the fixing blocks 22. At the same time, a motor 21 is installed outside the fixing blocks 22. A screw connection block 24 is screwed on the outer side of the double-threaded screw rod 25. And a connection block 26 is connected to the outer end of the screw connection block 24. At the same time, a clamping block 27 is connected to the outer end of the connection block 26. And a guide rod 23 is slidably penetrated through the connection block 26. The guide rod 23 is connected between the two fixing blocks 22.

[0028] As a preferred implementation method, by setting two groups of clamping blocks 27, the stability of the installation with the longitudinal beam of the support is strengthened. By setting the guide rod 23 to be slidably connected to the connection block 26, the clamping block 27 makes a linear motion.

[0029] During use, place the installation component on the lower side of the whole device inside the bracket on the lower side of the coal conveying belt, and place the clamping blocks on both sides of the longitudinal beam of the bracket. Then start the motor to drive the clamping blocks to move closer and clamp the longitudinal beam to complete the installation, which is relatively convenient. If it needs to be installed on the wall, first remove the second bolt, then flip the bottom plate to a direction parallel to the outer edge of the base, and then fix the bottom plate through the first bolt. At this time, place the detection device under the belt, then align the clamping blocks with the positioning plate installed on the wall, and then also start the motor to clamp the positioning plate through the clamping blocks to complete the fixation. With the support rod, cross bar and nylon cloth included in the protection component, when sewage or coal material falls on the nylon cloth, the nylon cloth is pressed downwards, and then touches the detection end of the pressure sensor. The pressure sensor sends a signal to the electric push rod, causing the electric push rod to start pushing the first cross bar upwards, thereby lifting one end of the nylon cloth upwards to make it in an inclined state, so that the sewage and coal material on the upper side slide down by their own weight.

[0030] The coal conveying belt flaw detection device of the present utility model can effectively solve the problems of poor practicability of the existing coal conveying belt flaw detection device and lack of self-protection of the flaw detection device, realizing that on the basis of the existing coal conveying belt flaw detection device technology, it has two installation methods, increasing the practicability, and at the same time having the effects of self-waterproofing, preventing damage caused by falling materials or affecting the flaw detection work.
