Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation equipment technology, and in particular to a tail guard protection device for a coal mine belt conveyor. Background Technology

[0002] In coal mine production, belt conveyors are important coal transportation equipment. As one of the key parts of the belt conveyor, the safety protection of the tail section is of paramount importance. This requires a protective cover, which is installed at the tail section for protection.

[0003] Currently, the protective cover is prone to deformation or even damage when subjected to external forces such as coal impact and equipment vibration, and cannot provide long-term stable protection for the tail section. Specifically, when the tail cover deforms, loosens and falls off, there is a lack of a mechanism for linkage protection with the belt conveyor. The belt conveyor will not stop, and there is a risk of operational damage to the tail section. Therefore, this utility model proposes a tail cover protection device for coal mine belt conveyors to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a tail cover protection device for a coal mine belt conveyor. This device uses a fixing pin that passes through a pad and a transport support to secure the cover to the support. A connecting wire is connected below the fixing pin. When the cover loosens or falls off, the fixing pin loosens, pulling the connecting wire and causing the drum to rotate. An encoder measures the drum's rotation stroke. When a set stroke threshold is triggered, a microcontroller is activated. The microcontroller connects to a controller to shut down the conveyor and stop the equipment, thus improving the efficiency of tail cover protection.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a tail guard protection device for a coal mine belt conveyor, including a transport support and a cover body. The cover body is located at one end above the transport support, and pads are provided on both sides below both ends of the transport support. Fixing pins are inserted into the pads, and the lower ends of the fixing pins pass through the transport support and are fixed.

[0006] Encoders are installed on both sides inside the transport bracket. A rotating drum is installed on the encoder for resetting rotation. A winding group is wound on the rotating drum, and there are at least two winding groups. The connecting wires of the two winding groups are respectively connected to the fixing pins at both ends. The signal output terminal of the encoder is connected to a microcontroller, and the control terminal of the microcontroller is connected to the controller of the transport body.

[0007] A further improvement is that the fixing pin includes a top and a pin body, the pin body is located at the lower end of the top and passes through the pad, and the transport bracket is provided with a fixing hole through which the pin body passes.

[0008] A further improvement is that: side grooves are provided on both sides of the pin body, and a limiting piece is provided inside the side groove for rotation. The limiting piece is used to lock into both sides below the fixing hole, and a spring is connected between the limiting piece and one side inside the side groove.

[0009] A further improvement is that the upper end of the limiting piece is provided with a locking head, which is used to lock into the upper end of the side groove, and the locking head limits the rotation angle of the limiting piece.

[0010] A further improvement is that: the lower end of the pin body is provided with a connecting hole, and a connecting hook is provided on the connecting line, the connecting hook being adapted to the connecting hole.

[0011] Further improvements are made in that: the connecting line is used to pull the rotating drum to rotate, the encoder is used to measure the rotational stroke of the rotating drum and trigger the microcontroller, and the microcontroller is used to connect to the controller to control the opening and closing of the transport body.

[0012] A further improvement is that the cover is positioned above the tail of the transport support machine, and the side wall of the cover is provided with reinforcing ribs. The cover and the pad are integrally formed.

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

[0014] 1. This utility model uses a fixing pin that passes through the pad and the transport bracket to fix the cover to the transport bracket. A connecting line is connected below the fixing pin. When the cover becomes loose or falls off, the fixing pin loosens and pulls the connecting line, causing the drum to rotate. The encoder measures the rotation stroke of the drum. When the set stroke threshold is triggered, the microcontroller is started. The microcontroller is used to connect to the controller to control the transport body to close and stop the equipment operation, thus improving the efficient protection of the tail.

[0015] 2. When installing the cover, this utility model only requires passing the pin of the fixing pin through the fixing hole of the pad and the transport bracket. Under the elastic action of the spring, the limiting plate pops out and locks into both sides below the fixing hole, thereby fixing the cover. When disassembling, simply press the limiting plate to make it rotate and retract into the side groove, and the fixing pin can be pulled out from the fixing hole. No complicated tools are required for installation and disassembly. A single person can complete the operation in a short time, which is convenient for the inspection and replacement of the protective facility components. Attached Figure Description
