Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to a hydraulic oil cylinder limit switch device of an incinerator. Background Art

[0002] In the incinerator system, the stability and accuracy of the hydraulic cylinder stroke signal is an issue that requires long-term consideration. The stable and reliable stroke feedback device of the hydraulic cylinder and the cylinder directly affects the safety and stability of the incinerator combustion system.

[0003] The domestic waste incinerator provided by China Patent No. 02111455.2 includes a hopper door, a reverse grate, a forward grate, a material layer adjustment, and a slag discharger. Each part has a different number of hydraulic cylinders. In actual combustion control, due to the harsh environment and the limited performance of existing switches in the market, the stroke signal of the hydraulic cylinder often has a bad point or does not move.

[0004] In the two-stage domestic waste incinerator with adjustable material layer provided by Chinese Patent No. 200610052844.6, the stroke signals of each hydraulic cylinder are often unreliable.

[0005] The existing travel sensors on the market are expensive and difficult to replace, and have low practicality in actual incinerator applications. For example, the service life of inductive proximity switches generally does not exceed three months in harsh industrial environments. Another example is the mechanical travel switch, which does not have a matching mounting bracket, so the work of accurately changing the position in a harsh environment is extremely complicated. The rope travel encoder is not recognized by the owner in actual applications due to its expensive price and the disadvantage that the wire hole is easy to get dust. In general, the travel switch is used in the actual control of the oil cylinder, so the accuracy of the switch signal directly affects the smooth performance and safety and reliability of the entire system.

[0006] This design uses a universal limit switch and customizes a bracket for it, which can facilitate the replacement of the limit switch position and ensure the accuracy and reliability of the signal at a very low price. Utility Model Content

All equipment is a mechanical structure, so that the hydraulic cylinder of the incinerator can stably output a stroke signal when moving in a harsh environment.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

Both ends of the slide rail are fixed to the cylinder body through fixing parts. An opening slot is arranged on the slide rail. The limit switch is installed in the opening slot through bottom screws and can move freely along the length of the opening slot. One end of the hook frame is installed on the cylinder moving part of the cylinder, and the other end thereof extends to the limit switch to indirectly trigger the induction signal of the limit switch through the displacement of the cylinder.

[0010] Preferably, the limit switch comprises at least two groups, the two groups of limit switches are arranged at both ends of the cylinder body, the two groups of limit switches are respectively used to respond to the advance and retreat of the cylinder, and an induction collision rod is arranged on the top of the limit switch.

[0011] Preferably, the hook frame is an L-shaped rod, the long rod end of which is fixed to the moving part of the cylinder through the hook frame base, and the short rod of which extends between the induction striker rods of the two groups of limit switches.
