Abstract
The utility model relates to a scraper chain monitoring-protecting device comprising a travel switch, a spring and a supporting plate, wherein the travel switch is arranged on a scraper deslagging machine and connected into an electric-motor circuit of a scraper deslagging system; one end of the supporting plate is arranged below a scraper chain, while the other end supports an ejector rod of the travel switch; and one end of the spring is fixed on the scraper deslagging machine, while the other end is connected with the supporting plate. The scraper chain monitoring-protecting device is simple in structure and convenient to use and can monitor the operation of the scraper chain in time, reduce the production accidents to the greatest extent, and ensure the normal operation of the equipment.
Description
Technical field
The utility model relates to a kind of supervising device, particularly relates to a kind of flight chain monitoring and protecting device.
Background technology
The slag system that removes in present civilian heating boiler room often adopts the flight chain slagging-off, and chain, slide block etc. are consumable accessory, and operation a period of time will break down, and need tighten, overhauls or change chain again.In the past, can only lean on the people near slag remover, to make an inspection tour, whether monitoring is normal except that the slag system operation, and whether it is long whether flight chain stretches, need to tighten etc., that finds sometimes is untimely, will impact production, remove slag system and stop transport, will blowing out, heating system is out of service, thereby has influenced hot user's normal heating.
Summary of the invention
The utility model has overcome deficiency of the prior art, and flight chain monitoring and protecting device a kind of simple in structure, easy to use is provided.
In order to address the above problem, the utility model by the following technical solutions:
The flight chain monitoring and protecting device comprises travel switch, spring and supporting plate, and travel switch is installed on the scraper plate slag remover and inserts in the scraper plate slagging-off system motor circuit; Supporting plate one end is positioned at the flight chain below, and an end withstands on the push rod of travel switch, and spring one end is fixed on the scraper plate slag remover, and an end is connected with supporting plate.
Compared with prior art, the beneficial effects of the utility model are:
The utility model device is by the break-make of supporting plate control travel switch inner contact, regulate the supporting plate height by spring, thereby the stretching of stable control flight chain, operation conditions that can the effective monitoring flight chain, on-call maintenance or replacing, the influence that has reduced the production accident rate to greatest extent and hot user is heated has good economic benefits and social benefit.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 vertical view.
The specific embodiment
The flight chain monitoring and protecting device as shown in Figure 1 and Figure 2, comprises travel switch 5, spring 2 and supporting plate 3, and travel switch 5 is installed on the scraper plate slag remover and inserts in the scraper plate slagging-off system motor circuit; Supporting plate 3 one ends are positioned at flight chain 4 belows, and an end withstands on the push rod of travel switch 5, and spring 2 one ends are fixed on the scraper plate slag remover, and an end is connected with supporting plate 3.
6 runnings of scraper plate slagging-off system motor drive scraper plate driving shaft 1 and rotate, and scraper plate driving shaft 1 drives flight chain 4 operate as normal.After running a period of time, flight chain 4 phenomenon long or that damage that may occur stretching, flight chain 4 stretches long or when damaging, the top chain sinks and presses supporting plate 3, supporting plate 3 sinks, and then supporting plate 3 unclamps the push rod of travel switch 5, makes travel switch 5 inner contact disconnect, scraper plate slagging-off system motor 6 is out of service and pass to the stokehold by recoil simulator and report to the police, and the expression scraper plate breaks down.The maintenance personal can in time overhaul processing to flight chain 4, and flight chain 4 is returned within the length range of work permission.After maintenance finishes, drive supporting plate 3 by spring 2 and rise, then the push rod of supporting plate 3 jack-up travel switches 5 makes travel switch 5 contacts reset, and scraper plate removes slag system and returns to normal operating conditions.
