Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chain plate conveyors, in particular to an automatic stop limit device for a chain plate conveyor. Background Art
[0002] A chain conveyor is a chain conveyor, which is mainly composed of a conveying chain, a driving device, a tensioning device, a guiding device, etc. The conveying chain is composed of a chain and a chain. The chain carries the operation of the chain, and the chain carries the transportation of materials. The driving device is usually composed of an electric motor, a reducer and a sprocket, etc. The driving device can provide power for the conveyor. During the operation of the chain conveyor, the automatic stop limit device is the main device to ensure the safe operation of the chain conveyor.
[0003] The current automatic stop limit device relies on a mechanical mechanism to perform an emergency stop on the chain conveyor. When the chain breaks or slips, the speed of the driven shaft on the chain conveyor will drop significantly or even be zero. At this time, the automatic stop limit device can drive the mechanical mechanism to perform an emergency stop on the chain conveyor. However, this means that the automatic stop limit device needs to monitor the speed of each driven shaft on the chain conveyor at all times. When the speed of the driven shaft is lower than the set value, the automatic stop limit device will be automatically activated. Utility Model Content

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] Embodiment 1
[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the automatic stop limit device of the chain plate 3 machine includes a bracket 1, the upper end of the bracket 1 is fixedly connected with oppositely arranged side plates 2, a chain plate 3 driven by a driving device is arranged between the side plates 2 on both sides, side special-shaped plates 6 cooperating with the chain plate 3 are arranged on the side plates 2 on both sides, and mounting grooves 7 cooperating with the side plates 2 are arranged in the side special-shaped plates 6 on both sides, the mounting grooves 7 are fixedly connected to the side plates 2, and at least one mounting hole is arranged in the mounting grooves 7.
[0023] Through the above structure, the driving device can drive the chain plate 3 to move. How to improve safety redundancy during operation? The specific structure is as follows:
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the side special-shaped plates 6 on both sides are provided with moving surfaces 10 cooperating with the chain plates 3, and the side special-shaped plates on both sides are provided with at least one and evenly arranged infrared sensors 9 on one side of the moving surface 10, and the infrared sensors 9 are arranged equidistantly, and the chain plates 3 are provided with infrared sensing modules cooperating with the infrared sensors 9, and the side special-shaped plates are provided with timing modules electrically connected to the infrared sensors 9 and control modules electrically connected to the timing modules, and the control module is electrically connected to the automatic shutdown limit mechanism, and one side of the infrared sensor 9 is provided with a partition plate 8 cooperating with the chain plate 3, which can avoid collision between the infrared sensor 9 and the chain plate 3.
[0025] Through the above structure, safety redundancy can be improved.
[0026] Embodiment 2
[0027] like Figure 1 and Figure 2 As shown, at least one evenly arranged fixing member 4 is provided on one side of the side panel 2, and an infrared detection transmitter 5 cooperating with the infrared sensing module is fixedly connected to the fixing member 4, and the infrared detection transmitter 5 is electrically connected to the timing module.
[0028] Through the above structure, the infrared detection transmitter 5 cooperates with the timing module and the infrared sensing module to improve the accuracy of monitoring.
[0029] During the specific implementation of the utility model, when the chain plate is used to convey materials, the driving device drives the chain plate to move between the side plates on both sides, and the chain plate located on the upper end surface moves on the moving surfaces on the two side special-shaped plates. During the movement, the partition plate can prevent the chain plate from colliding with the infrared sensor, and when the infrared sensing module in each chain plate monomer passes through the infrared sensor arranged at a certain distance, the infrared sensor will generate infrared induction with the infrared sensing module. According to the time interval of the same infrared sensing module sensed by multiple infrared sensors evenly arranged at a certain distance, it can be determined whether the time taken by the chain plate monomer to move a certain distance meets the design value. If it is greater than the design value, the transmission between the driving device and the chain plate is abnormal, resulting in the chain plate failing to transmit in time. In this way, the control module can control the automatic shutdown limit mechanism to perform an emergency shutdown on the chain plate, and the infrared detection transmitter can also perform induction monitoring on the infrared sensing module, which can improve the accuracy of monitoring.
[0030] The driving device drives the chain plates to move on the moving surfaces on both sides. Each chain plate unit is equipped with an infrared sensing module. Together with at least one evenly arranged infrared sensor on one side of the moving surface and the timing module in the side special-shaped plate, the time taken by each chain plate unit to move a certain distance can be monitored. In this way, by comparing the movement rate of the chain plates, it can be determined whether the transmission between the driving device and the chain plates is normal, thereby improving safety redundancy.
