Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment technology, and in particular to a protective device for preventing the chain plate of a mining feeder from warping. Background Technology

[0002] In the current industrial technology field, the GBZ150-9 heavy-duty plate feeder for mining is a key material conveying equipment. Its working principle is as follows: the variable frequency speed-regulating motor is used as the core power source to drive the orthogonal planetary reducer to run. Then, through the precise meshing of the sprocket and chain on the drive shaft, the single arc plate chain plate is driven to achieve uniform linear motion, and finally the material carried by the chain plate is smoothly conveyed to the next production process.

[0003] However, in actual operation, this equipment faces a pressing technical challenge. When the tail-end chain plate experiences a sudden and abnormal force change, it is highly susceptible to abnormal warping. This warping not only causes severe scraping between the chain plate and the upper hopper liner, but also, when the warping height exceeds the safe clearance between the hopper liner and the chain plate, it can lead to a series of serious consequences. Specifically, it may cause the feeder motor to burn out and stop due to overload, or the chain plate bolts to break due to excessive shear force, thereby affecting the safe and stable operation of the entire production line.

[0004] To address the aforementioned issues, from the perspective of ensuring equipment safety and improving production efficiency, it is particularly necessary to design and install a highly efficient and reliable safety protection device to prevent chain plate warping. This device should possess functions such as real-time monitoring, rapid response, and precise control to ensure timely intervention when the chain plate experiences sudden changes in stress, effectively preventing chain plate warping and thus avoiding equipment damage and production accidents. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a protective device for preventing the chain plate of a mining feeder from warping.

[0006] An embodiment of this utility model provides a protective device for preventing the chain plate of a mining feeder from warping, comprising:

[0007] A support frame on which a chain conveyor is mounted;

[0008] Anti-tilting assembly; the anti-tilting assembly includes two protective plates fixed on a bracket, the protective plates being fitted over the outside of the chain conveyor;

[0009] Protection components; there are two protection components fixed on the bracket, and the protection components are capable of monitoring the tilted chain plate.

[0010] Furthermore, the chain conveyor includes sprockets rotatably mounted on a support, with chains wound around two sprockets along the length of the support, and the chain plates mounted on the chains.

[0011] Furthermore, the protective plate has the same shape as the distribution of the multiple chain plates and is located outside the chain plates.

[0012] Furthermore, the protection component includes an L-shaped plate fixed on a bracket, a sleeve fixed to the bottom of the L-shaped plate, a sliding block slidably connected inside the sleeve, a pressure sensor fixed to the bottom of the L-shaped plate, a spring fixed to the pressure sensor and the sliding block, a wheel frame fixed to the bottom of the sliding block, and a rotating wheel rotatably mounted on the wheel frame that abuts against the chain plate.

[0013] Furthermore, both the sleeve and the sliding block are rectangular in shape.

[0014] Furthermore, the pressure sensor is a resistive strain gauge sensor, a piezoresistive sensor, or a capacitive pressure sensor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention uses a protective plate to limit the end of the chain plate, preventing it from continuing to tilt upwards and thus avoiding scraping between the chain plate and the liner of the hopper. This prevents the chain plate from tilting and protects the device. When the pressure sensor is squeezed, it sends a signal, which, through the controller, stops the chain conveyor, thereby reducing scraping between the chain plate and the protective plate.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a protective device for preventing the chain plate of a mining feeder from warping, comprising:

[0024] A support frame 1 is provided, on which a chain conveyor 5 is mounted. The chain conveyor 5 includes sprockets 2 rotatably mounted on the support frame 1, and chains are wound around two sprockets 2 along the length of the support frame 1. Chain plates are mounted on the chains.

[0025] Anti-tilting component; The anti-tilting component includes two protective plates 3 fixed on the bracket 1. The protective plates 3 are sleeved on the outside of the chain conveyor 5. The shape of the protective plates 3 is the same as the shape of the multiple chain plates and is located outside the chain plates. When the chain plates are hit by external force and abnormal tilting occurs, the protective plates 3 can limit the end of the chain plates, preventing them from tilting upwards. This prevents the chain plates from rubbing against the liner of the hopper, thus preventing the chain plates from tilting and protecting the device.

[0026] Protection components; There are two protection components and they are fixed on the bracket 1. The protection components can monitor the tilted chain plate. The protection components include an L-shaped plate 4 fixed on the bracket 1. A sleeve 6 is fixed to the bottom of the L-shaped plate 4. A sliding block 7 is slidably connected inside the sleeve 6. Both the sleeve 6 and the sliding block 7 are rectangular in shape, so that they will not rotate.

[0027] A pressure sensor 10 is fixed to the bottom of the L-shaped plate 4. The pressure sensor 10 is a resistive strain gauge sensor, a piezoresistive sensor, or a capacitive pressure sensor. A spring 11 is fixed to the pressure sensor 10 and the sliding block 7. A wheel frame 8 is fixed to the bottom of the sliding block 7. A rotating wheel 9 that abuts against the chain plate is rotatably mounted on the wheel frame 8. When the chain plate is raised and abuts against the protective plate 3, part of the chain plate will move upward. When this part moves below the rotating wheel 9, it will drive the rotating wheel 9, the wheel frame 8, and the sliding block 7 to move upward. The upward movement of the sliding block 7 compresses the spring 11, and the spring 11 will compress the pressure sensor 10. The pressure sensor 10 is compressed and sends a signal, which controls the controller to stop the chain plate conveyor 5 from working, thus reducing the friction between the chain plate and the protective plate 3.

[0028] The pressure sensor 10 sends a signal when squeezed, which controls the drive chain conveyor 5 to stop working through the controller. This part is the same as the alarm principle when the motor is overloaded.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
