Problems solved by technology
First of all, when the number of wire ropes wound on the encoder shaft is too many, it is easy to get stuck
Secondly, the wire rope wound on the encoder shaft has a large degree of bending, and it is easy to break the rope after repeated winding
Finally, this device easily damages the delicate encoder during disassembly and maintenance.

Embodiment
[0023] Embodiment: A method for measuring the stroke of the waste incinerator grate oil cylinder. The linear motion of the oil cylinder is converted into the rotation of the pulley, and the amount of rotation is detected by an encoder that rotates synchronously with the pulley.
[0024] The waste incinerator grate oil cylinder stroke measuring device includes a steel wire rope 10, one end of which is fixed on the movable end of the oil cylinder 60, the middle part of the steel wire rope 10 passes through several guide pulleys 50, and the other end of the steel wire rope 10 bypasses the conversion pulley 20 and is connected with a tensioning device 30 The 3mm steel wire rope 10 winds 2 turns on the conversion pulley 20. The tensioning device 30 is a heavy hammer weighing about 1 kg.
[0025] The conversion pulley 20 is connected with an encoder 40 through gear transmission. The side of conversion pulley 20 is provided with slide bar 21, and slide bar 21 is fixed, and slide bar...

The invention discloses a garbage incineration grate oil cylinder stroke measuring method. The method comprises the steps of converting the linear motion of an oil cylinder into the rotation of a pulley; detecting the rotation amount through an encoder (40) which synchronously rotates with the pulley; and converting the rotation amount in equal proportion to realize the measurement of the stroke of the oil cylinder. The device comprises a steel wire rope (10). One end of the steel wire rope (10) is fixed to the movable end of an oil cylinder, and the other end of the steel wire rope (10) bypasses a conversion pulley (20) and then is connected with a tensioning device (30). The conversion pulley (20) is connected with an encoder (40). The method and the device have the characteristics of stable operation, good measurement effect and small equipment damage risk. In addition, the device provided by the invention is simple in structure and good in economic benefit.
Description
technical field [0001] The invention relates to a method and a device for measuring the stroke of an oil cylinder, in particular to a method and a device for measuring the stroke of an oil cylinder for waste incineration grate. Background technique [0002] The reverse push of the grate used in waste incineration and the oil cylinder of the pusher need to monitor its stroke in real time to control the incineration efficiency. Due to the relatively harsh on-site environment, the stroke of the oil cylinder is generally converted and transmitted to the off-site for monitoring. The existing measurement method is to use a steel wire rope, distribute and fix its two ends on the oil cylinder and the encoder shaft, convert the linear motion of the oil cylinder into the rotation of the encoder shaft, and then transmit the number of rotations of the encoder to the PLC, and then further Pass it to DCS equipment for barcode display. [0003] However, there are several problems with th...
