Description

Technical Field

[0001] This utility model relates to a detection alarm device, specifically a chain breakage detection alarm device, belonging to the field of chain breakage detection alarm technology. Background Technology

[0002] The chain breakage detection alarm, equipped with a speed sensor, operates primarily on the principle of electromagnetic induction. The speed sensor is mounted on the driven shaft of the conveyor and rotates with it, converting the rotational speed signal into a pulse signal. When the chain is running normally, the frequency of the pulse signal emitted by the speed sensor is proportional to the rotational speed of the driven shaft. If the chain breaks, the conveyor speed will change, such as underspeed or slippage, and the frequency of the pulse signal emitted by the speed sensor will change accordingly. When the pulse signal frequency falls below a set value, the signal processor receives a switching signal and outputs a switching signal to control the drive motor to stop running, thereby protecting the equipment.

[0003] However, existing chain break protectors are manufactured with relatively long connecting wires to the signal processor for practicality. This facilitates subsequent installation of the chain break protector. During the fixing process, the excess connecting wires are mostly bundled and stored with cable ties. When the position of the chain break protector needs to be adjusted, the cable ties must be cut to adjust the length of the wires, which is cumbersome and inconvenient for quick storage of the connecting wires. Utility Model Content

[0004] The purpose of this invention is to provide a chain breakage detection alarm device to solve the above problems. The pull rod slides and compresses the telescopic spring, causing it to drive the stop rod to slide along the slide bar. This allows the connecting wire of the signal processor to be wrapped around the hanging bracket, thereby preventing the connecting wire from falling off.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a chain breakage detection and alarm device, comprising a signal processor, a speed sensor fixedly mounted on the signal processor, a chain breakage protector electrically connected to the signal processor, a fixing mechanism mounted on the signal processor, a mounting frame fixed on the fixing mechanism, a hanging mechanism fixed on the mounting frame, the hanging mechanism comprising a hanging bracket and a pad, a hanging bracket fixedly connected to the mounting frame, a pad and a fixing rod fixedly mounted on the hanging bracket, a sliding groove provided on the fixing rod, a pull rod slidably mounted on the sliding groove, a stop rod fixedly connected to the pull rod, a sliding rod fixedly connected to the fixing rod, a telescopic spring sleeved on the sliding rod, and the pull rod abutting against the telescopic spring.

[0006] Preferably, the abutment rod and the wire hanger are slidably connected, and the part of the wire hanger that contacts the pad has an arc-shaped structure.

[0007] Preferably, the abutment rod and the slide rod are slidably connected, the pull rod and the fixing rod are slidably connected, and the slide rod is configured in a T-shape.

[0008] Preferably, the mounting bracket is L-shaped, and the end of the pull rod away from the fixed rod is arc-shaped.

[0009] Preferably, the fixing mechanism includes a locking block and a stop plate. Two sets of stop plates are locked onto the signal processor. A locking block is fixedly connected between two adjacent stop plates. The locking block has a through hole. A connecting plate is fixedly installed at the end of the stop plate.

[0010] Preferably, both of the card blocks are located at the center of both ends of the signal processor, and the card blocks are in contact with the signal processor.

[0011] Preferably, the abutment is L-shaped, and the part of the signal processor that contacts the abutment is arc-shaped.

[0012] Preferably, a mounting bracket is fixedly connected to the connecting plate, and the mounting bracket is located on the side wall of the connecting plate away from the signal processor.

[0013] Preferably, the two ends of the connecting plate are fixedly connected to the abutment plate by fixing bolts, and the through hole is circular.

[0014] The beneficial effects of this utility model are as follows: When it is necessary to store the connecting wires of the signal processor, the operator can pull the lever by hand. A stop rod is fixedly connected to the lever. When the lever slides in the groove provided in the fixed rod, it can slide along the side wall of the slide rod. A telescopic spring is sleeved on the slide rod. When the lever slides, its end can squeeze the telescopic spring. When the telescopic spring is in a compressed state, the lever can drive the stop rod to slide into the inside of the hanging frame and the fixed rod. The hanging frame is fixed to the side wall of the mounting bracket. When the connecting wires of the signal processor are wound around the hanging frame, the connecting wires can be stored. The hanging frame is also attached with a gasket, which can prevent the connecting wires from being broken. After the wires are stored, the operator can release the lever. Under the reaction force of the telescopic spring, the lever drives the stop rod to return to its original position, thereby limiting the connecting wires and preventing them from falling off the hanging frame.

[0028] As a technical optimization of this utility model, the fixing mechanism 4 includes a locking block 401 and abutment plate 402. Two sets of abutment plates 402 are locked onto the signal processor 1. A locking block 401 is fixedly connected between two adjacent abutment plates 402. A through hole 404 is provided on the locking block 401. A connecting plate 403 is fixedly installed at the end of the abutment plate 402. The two sets of abutment plates 402 can be installed on the signal processor 1 through the connecting plate 403.

[0029] As a technical optimization of this utility model, both of the card blocks 401 are located at the center of both ends of the signal processor 1. The card blocks 401 are in contact with the signal processor 1. The through hole 404 allows the card blocks 401 to pass through the connecting wires.

[0030] As a technical optimization of this utility model, the abutment plate 402 is arranged in an L-shape, and the part of the signal processor 1 that contacts the abutment plate 402 is arranged in an arc-shaped structure.

[0033] In use, the operator first places the two sets of abutment plates 402 at both ends of the signal processor 1. Then, using fixing bolts, the two ends of the connecting plate 403 are fixedly installed together with the ends of the abutment plates 402, thereby fixing the abutment plates 402 onto the signal processor 1. A mounting bracket 5 is fixedly connected to the connecting plate 403, and the signal processor 1 is fixed to the equipment via the mounting bracket 5.

The pull rod 604 drives the stop rod 605 to reset under the reaction force of the telescopic spring 608, thereby limiting the connecting wire and preventing it from falling off the hanging bracket 601. The speed sensor 2 installed on the signal processor 1 can monitor the rotation speed of the driven shaft or conveyor. When the chain is intact, the driven shaft will maintain a certain speed. If the chain breaks or slips, the rotation speed of the driven shaft will drop significantly. The speed sensor 2 can detect this change. When the rotation speed is lower than the preset threshold, it can send a signal to the control system to stop the drive motor.
