Problems solved by technology

In conveyors driven by chains such as chain plate conveyors and chain conveyors, due to the long length of the chain and its heavy weight, the chain needs to be tensioned during installation, and after a certain period of running and traction, the chain is normal. Wear and tear will cause the chain to stretch to a certain extent, resulting in a gradual increase in the sag of the chain. In this way, the tension of the chain is not enough, the chain will jump violently, and the phenomenon of loose chain, running chain, chain jamming, and broken chain will easily occur. Will damage the equipment, but also pose a safety hazard

Embodiment Construction

[0007] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0008] See figure 1 , the present invention comprises a frame 1 and a sprocket 2, the frame 1 is provided with a slide rail 3, the axle of the sprocket 2 is mounted on a slide block 4, the slide block 4 is mounted on the slide rail 3, the slide block 4 is connected to a screw rod 6, and the screw rod 6 After the spring 7 is set, the frame 1 is passed through, and an induction nut 8 is installed at the end thereof, and a sensor 9 is installed on the frame 1 under the induction nut 8 .

[0009] Once the chain 5 of the chain conveyor is stretched, the spring 7 will simultaneously push the screw 6 and the sprocket 2 outwards to ensure the tension of the chain 5 . When the stretching of the chain 5 reaches a certain amount, when the induction nut 8 on the screw rod 6 approaches the position of the sensor 9, the sensor 9 senses the proximity of the...

Abstract

The invention provides a chain tension checking device. The chain tension checking device can be used for regulating the tension of a chain, the chain is effectively prevented from taking off, and the service life of the chain tension checking device is prolonged. The chain tension checking device comprises a rack and a chain wheel, wherein the chain wheel is in mesh transmission with the chain, and the chain is fixedly provided with a chain board. The chain tension checking device provided by the invention is characterized in that the rack is provided with a sliding rail, a wheel shaft of the chain wheel is arranged on a sliding block, the sliding block is arranged on the sliding rail, the sliding block is connected to a screw rod, the screw rod penetrates through the rack after being sleeved with a spring, the tail end of the screw rod is sleeved with an induction nut, and a sensor is arranged under the induction nut and is arranged on the rack.

Description

technical field [0001] The invention relates to the field of chain conveyor devices, in particular to a chain tension inspection device. Background technique [0002] The chain conveyor is a kind of equipment that can realize the automatic transportation of materials. It has the advantages of flex fatigue resistance, good impact resistance, large transportation capacity, stable start, safety, etc., making it widely used in industrial production and logistics transportation. and other fields. In conveyors driven by chains such as chain plate conveyors and chain conveyors, due to the long length of the chain and its heavy weight, the chain needs to be tensioned during installation, and after a certain period of running and traction, the chain is normal. Wear and tear will cause the chain to stretch to a certain extent, resulting in a gradual increase in the sag of the chain. In this way, the tension of the chain is not enough, the chain will jump violently, and the phenomenon...
