Burner hearth bottom certain position is stopped, and as the extreme lower position of inspection platform, inspection platform is raised to one positioning of roof of the furnace then
Put and stop, as the extreme higher position of inspection platform, then just allow inspection platform to move between these two positions.But this
It is to design in theory.More problems in actual mechanical process, main cause are that inspection platform deadweight loading is loaded with 6-7 tons, are undertaken
Constantly extend after the steel wire rope stress of inspection platform weight, cause the spacing high constantly change for arranging, need constantly to adjust, no
But increase trouble, and easily cause security incident.
Utility model content
The purpose of this utility model is：For the problem that above-mentioned prior art is present, there is provided a kind of inspection platform height
Stopping means, by the stationary positioned mechanism inside the burner hearth, determine extreme lower position and the extreme higher position of inspection platform, change biography
System by rope capacity position, this new limit method, one-time positioning, put things right once and for all, very accurately, it is ensured that maintenance
The safe operation of platform.
Technical solutions of the utility model are as follows：A kind of inspection platform height limiting device, including the limit being used in conjunction with each other
Position mechanism and detent mechanism；The position-limit mechanism includes the installing plate on inspection platform auxiliary girder, sets on the installing plate
Two limit switches for having upper and lower position to arrange；The detent mechanism includes two sets in boiler furnace on water-cooling wall
Locating support, the locating support have two, are provided with retention bar between two support arms of each locating support, described spacing
Switch is touched with retention bar when running up and down.
Further, the limit switch has two, the first limit switch including upper-lower position arrangement and standby the
Two limit switches.
Further, the installing plate is U-shaped installing plate, and the U-shaped installing plate is plugged on inspection platform auxiliary girder, and is led to
Cross fixed knob to be fixedly connected.
Further, the locating support is T row supports, and the locating support is by one of T-shaped support equipped with rubidium ferrum
Boron magnets can be positioned at support in burner hearth on water-cooling wall fin, between adjacent water cooling tube.
Further, the locating support is fixed on water-cooling wall by countersunk head screw.
Further, the locating support can rotate the positioning for adapting to vertical water wall and helical water-cooled wall by screw
On water-cooling wall in burner hearth.
Further, the locating support can also be rotated by screw and adapt to distance between inspection platform and water-cooling wall
Adjustment.
This utility model has the beneficial effect that：This utility model inspection platform height limiting device, by inside burner hearth
Stationary positioned mechanism, determines extreme lower position and the extreme higher position of inspection platform, change it is traditional positioned by rope capacity,
This new limit method, very accurately, it is ensured that the safe operation of inspection platform.This utility model is provided with two and spacing opens
Close, once first limit switch is damaged, second limit switch is acted on immediately, it is ensured that travel limit.Limit switch is touched
After detent mechanism, motor stalling, inspection platform are stopped, and position determines.
