Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor protection technology, and in particular to a scraper conveyor tilting chain breakage protection device. Background Technology

[0002] Scraper conveyors are widely used in industries such as coal mining, metallurgy, and chemicals, undertaking the critical task of material conveying. In actual operation, scraper conveyors face complex and harsh working environments, such as the high humidity and dust levels at coal mining sites, as well as irregular impacts from materials. Once a scraper conveyor malfunctions, it not only leads to the interruption of conveying operations and affects production efficiency, but may also trigger a series of safety problems, such as debris splashing from a broken chain, and blockages caused by material accumulation leading to fires. Therefore, scraper conveyor protection is of paramount importance.

[0003] The existing scraper conveyor tilt and chain breakage protection device does not have an adjustment device during use, making it impossible to easily adjust the position of the detection part. When facing scraper conveyors of different widths, it cannot be adapted to the chain position, which will affect the detection and protection, resulting in the inability to accurately detect chain breakage or tilting. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a scraper conveyor tilting chain breakage protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A scraper conveyor tilting chain breakage protection device includes a protection component. The protection component includes a fixed bracket, with two sets of fixed brackets symmetrically arranged. An installation shaft is rotatably mounted on the fixed bracket, and an installation frame is slidably mounted on the installation shaft. Two sets of installation frames are provided. A tilting chain breakage detection sensor is mounted on one side of each installation frame. The installation shaft has several sets of fixing holes. The installation frame has openings adapted to the size and position of the fixing holes. A sleeve is mounted on one side of each installation frame, through which a fixing rod is slidably mounted. The size of the fixing rod is adapted to the openings of the installation frame. A fixing plate is slidably mounted inside the sleeve, fixed to one end of the fixing rod. A spring is mounted on one side of the fixing plate, and the other end of the spring is fixed to the sleeve. A height adjustment assembly is provided on one side of the fixed bracket, and an angle adjustment limiting assembly is provided on one side of the installation shaft.

[0007] As a further embodiment of this utility model: the mounting assembly includes a fixing plate, which is provided in two sets. The fixing plate has several sets of screw holes. A connecting frame is installed on the top of the fixing plate. An adjusting frame is slidably installed through the connecting frame. The top of the adjusting frame is fixed to the bottom of the fixing bracket. The adjusting frame has several sets of positioning holes arranged in sequence. The connecting frame also has positioning holes. A fixing pin can be detachably installed through the positioning holes.

[0008] As a further embodiment of this utility model: the limiting component includes a limiting pin, the limiting pin is U-shaped, and several sets of limiting holes are arranged in a circular pattern at both ends of the mounting shaft. A limiting hole is also provided on one side of the fixed bracket, and the limiting pin can be detachably installed in the limiting hole.

[0009] As a further improvement of this utility model: a gasket is installed at the bottom of the fixing plate, and the gasket is made of rubber.

[0010] As a further improvement of this utility model: a drive motor is installed on one side of the mounting bracket, and a transmission shaft is connected to the output end of the drive motor, with a cleaning brush installed on the transmission shaft.

[0011] As a further improvement of this utility model: a fan is installed on one side of the mounting bracket, an air intake is provided at the bottom of the fan, and an air outlet is connected to the top of the fan.

[0012] As a further improvement of this utility model: a handle is installed at the end of the fixing rod, and the handle is covered with a rubber sleeve.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The position of the mounting bracket can be adjusted arbitrarily through the protection components. The mounting bracket can be moved to a suitable position according to the position of the chain, thereby adapting to scraper conveyors of different widths. This avoids the situation where the position of the tilt chain breakage detection sensor is not compatible with the chain, which would affect the normal detection and protection. By setting a fixing rod in conjunction with a spring and fixing holes, the mounting bracket can be limited and fixed after the position is adjusted, preventing unnecessary displacement of the mounting bracket after the position is adjusted.

[0015] 2. By setting a limit component, the mounting shaft can be limited and fixed after the angle is finely adjusted according to the chain position, which can prevent the mounting shaft from rotating when not in operation, thus avoiding unnecessary angle adjustment of the mounting frame.

[0016] 3. The handle makes it easier to apply force to pull the fixing rod, making it easier to pull and preventing it from slipping out of your hand when pulling. Attached Figure Description

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example

[0024] Scraper conveyor tilt chain breakage protection device, such as Figure 1-4 As shown, the system includes a protective component, which includes a fixed bracket 1. Two sets of fixed brackets 1 are symmetrically arranged. A mounting shaft 9 is rotatably mounted on the fixed bracket 1. A mounting frame 7 is slidably mounted on the mounting shaft 9. Two sets of mounting frames 7 are arranged. A tilt chain breakage detection sensor 8 is mounted on one side of the mounting frame 7. The mounting shaft 9 has several sets of fixing holes 2. The mounting frame 7 has openings that match the size and position of the fixing holes 2. A sleeve 15 is mounted on one side of the mounting frame 7. A fixing rod 16 is slidably mounted through the sleeve 15. The size of the fixing rod 16 matches the opening of the mounting frame 7. A fixing piece 20 is slidably mounted inside the sleeve 15. The fixing piece 20 is fixed to one end of the fixing rod 16. A spring 19 is mounted on one side of the fixing piece 20. The other end of the spring 19 is fixed to the sleeve 15. A mounting component for adjusting the height is provided on one side of the fixed bracket 1. A limiting component for adjusting the angle is provided on one side of the mounting shaft 9.

[0025] In use, after installing the device on the scraper conveyor using the mounting components, the mounting bracket 7 can be controlled to slide on the mounting shaft 9. This allows the mounting bracket 7 to be adjusted to a suitable position according to the chain's position, adapting to scraper conveyors of different widths. This avoids situations where the tilting chain breakage detection sensor 8 is mismatched with the chain, affecting normal detection and protection. When adjusting the position of the mounting bracket 7, pulling the fixing rod 16 causes the fixing plate 20 to overcome the spring force of the spring 19 and move within the sleeve 15, moving one end of the fixing rod 16 out of the fixing hole 2. This movement controls the mounting bracket 7. After moving to the appropriate position, releasing the fixing rod 16 allows the spring force of the spring 19 to return the fixing rod 16 to its original position, moving it out of the mounting bracket 7. The hole is inserted into the fixing hole 2 for limiting and fixing, thereby avoiding unnecessary displacement of the mounting bracket 7 after the position is adjusted. The tilt chain breakage detection sensor 8 can detect tilt and chain breakage during the operation of the scraper conveyor. When the tilt chain breakage detection sensor 8 detects an abnormality, it sends an alarm signal and disconnects the control motor circuit to complete the alarm and stop the machine, avoiding further damage. It can facilitate timely detection and handling of faults. The model of the tilt chain breakage detection sensor 8 can be any sensor on the market. The connection between the tilt chain breakage detection sensor 8 and the control element can refer to any tilt chain breakage protection device of scraper conveyor on the market. No creative work has been put into it, so it is not described in detail.

[0026] The mounting assembly includes a fixing plate 13, which has two sets of fixing plates 13. The fixing plates 13 have several sets of screw holes. A connecting bracket 12 is installed on the top of the fixing plate 13. An adjusting bracket 11 is slidably installed through the connecting bracket 12. The top of the adjusting bracket 11 is fixed to the bottom of the fixing bracket 1. The adjusting bracket 11 has several sets of positioning holes arranged in sequence. The connecting bracket 12 also has positioning holes. A fixing pin 18 is detachably installed through the positioning holes.

[0027] When in use, the screw holes of the fixing plate 13 can be fitted into the bolts at the installation position of the scraper conveyor. After fitting, tighten the nut to complete the fixation. After the fixation is completed, the device can be installed to prevent the device from falling off during protection. The height of the mounting frame 7 can be adjusted by controlling the adjustment frame 11 to slide on the connecting frame 12. Adjusting the height makes it easy to adapt to chains of different heights and avoids the situation where the chain cannot be contacted. After adjusting to the appropriate height, the limiting holes and positioning holes of the connecting frame 12 and the adjustment frame 11 are aligned. After alignment, the fixing pin 18 can be inserted to complete the limit, thereby preventing the height from moving when not adjusted.

[0028] The limiting component includes a limiting pin 10, which is U-shaped. The two ends of the mounting shaft 9 are respectively arranged in a circular pattern and have several sets of limiting holes. The fixed bracket 1 also has a limiting hole on one side. The limiting pin 10 can be detachably installed in the limiting hole.

[0029] When in use, the size of the limit pin 10 is adapted to the limit hole. After the mounting bracket 7 is installed, its angle can be adjusted by rotating the mounting shaft 9. This facilitates fine-tuning so that the tilt chain breakage detection sensor 8 and the chain can fully contact for detection. After adjusting to a suitable angle, the two ends of the limit pin 10 are inserted into the limit holes of the fixing hole 2 and the fixing bracket 1, respectively, thereby limiting and fixing the mounting shaft 9. This can prevent the mounting shaft 9 from rotating when not in operation, which would cause unnecessary angle adjustment of the mounting bracket 7.

[0030] To reinforce the fixation, such as Figure 1 , 3 As shown, a gasket 14 is installed at the bottom of the fixing plate 13, and the gasket 14 is made of rubber.

[0031] When in use, the rubber gasket 14 can reinforce the fixing point when it is fixed by the fixing plate 13, and can fill the gaps at the fixing point to avoid loosening and shaking caused by gaps;

[0032] To clean the chain, such as Figure 1 , 2 As shown in Figure 4, a drive motor 4 is installed on one side of the mounting bracket 7, and a transmission shaft 6 is connected to the output end of the drive motor 4. A cleaning brush 5 is installed on the transmission shaft 6.

[0033] When in use, the cleaning brush 5 is positioned to match the chain after the device is installed. The drive motor 4 controls the rotation of the drive shaft 6 and the cleaning brush 5. The cleaning brush 5 cleans the chain by contacting it and removing dirt from its surface, thereby reducing the chance of chain breakage. After a certain period of use, the cleaning brush 5 can be removed and replaced mechanically.

[0034] To further remove attached dust and impurities, such as Figure 1 , 2 As shown, a fan 3 is installed on one side of the mounting bracket 7. The bottom of the fan 3 is provided with an air intake, and the top of the fan 3 is connected to an air outlet.

[0035] When in use, the fan 3 is started to draw in air through the air inlet and blow it out through the air outlet. The blowing can further clean the chain, thereby removing dust and impurities attached to the chain and preventing the continuous accumulation of dust and impurities from affecting the operation of the chain. Example

[0036] To facilitate pulling the fixing rod 16, refer to... Figure 3 The scraper conveyor tilt chain breakage protection device has the following improvements compared to embodiment 1: a handle 17 is installed at the end of the fixing rod 16, and the handle 17 is covered with a rubber sleeve.

[0037] When in use, you can hook your fingers on the handle 17 to make it easier to exert force to pull the fixed rod 16, which makes it easier to pull the fixed rod 16 and avoids the fixed rod 16 slipping out of your hand when pulling it.

[0038] The above description is only a preferred embodiment of the present utility model. For parts that do not require creative effort in circuit control, signal control and transmission, please refer to the prior art. However, the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
