Abstract
The utility model relates to a tooth harrow type trash-removal machine which is a trash removing device for channels and power stations without affecting the normal generating state (dynamic state). The trash-removal machine comprises a traveling track, a traveling mechanism, a winding device, a hoisting steel wire rope, an opening-closing steel wire rope and a tooth harrow type grab bucket, wherein the traveling track is installed on a moving rack, the traveling mechanism is installed on the traveling track, and the winding device is installed on the traveling mechanism and connected with the tooth harrow type grab bucket through the hoisting steel wire rope and the opening-closing steel wire rope. The trash-removal machine is installed on the moving rack and capable of moving a tooth harrow in three directions for grabbing trash, trash at a plurality of water inlets can be grabbed when the moving rack is moved, and because upper teeth and lower teeth can slide during normal trash removal, the upper teeth grab the trash under the action of lifting power. The trash-removal machine has the advantages that the structure is simple, the machine can be controlled manually or remotely, full-automatic control can be achieved through programmable logic controller (PLC), an opening-closing steel wire rope system is adopted to achieve opening and closing of the tooth harrow grab bucket and a scraper pan, and the defect that opening and closing of the existing trash-removal machine rely on self weight is overcome.
Description
Technical field
The utility model patent relates to a kind of tooth harrow formula trash rake; Belong to water conservancy machinery, be used for river course, power station, pumping plant, water inlet and remove contamination, promptly clear up life, natural slag things such as tree root, branch, tatter.
Background technology:
At present general trash rake mainly is to be used to clear up river course, power station, pumping plant upper reaches water float, to suspend and attached to the foreign material on the trashrack, because of receiving the influence of waters floating thing pollution, floating thing circles round, gathers with water; Form large stretch of thick accumulation horizon; Stopped up trashrack, the effective head of generating is reduced, head loss is very big; Cause the unit can not oepration at full load, thereby influence the normal power generation of unit.When water inlet is big more, pressure is just big more, and it is tight more that the slag thing is adsorbed on trashrack, piles manyly more more around water inlet slag thing, causes current not smooth, stops up water inlet.
The key of trash rake is to grab dirty ability, grabs the making capacity that dirty key depends on grab bucket, during traditional trash rake work, leans on slusher from the bucket of reclosing fully, and the slusher closing force is just very little during straight grid; The component that trash rake produces through the slusher deadweight when oblique grid is big, and the slusher closing force is just big, in lifting process owing to vibration when crossing the grid face, cross reason such as grid top bank and cause dirt to come off easily.The fluid pressure type trash rake is owing to adopt hydraulic system operation grab bucket to open and close; Closing force is by HYDRAULIC CONTROL SYSTEM; Irrelevant with lifting force, so just can improve closing force greatly, but owing to hydraulic system will be through cable power supply under water and carry out control operation; Cable when oblique grid since deadweight and generating produce the impact of moving water cause easily break or with breastwork, trashrack surface wear, head is more dangerous more greatly.The tradition trash rake only leans on the gravity of trash rake to sink to clearing up scum silica frost along drain grating; Lean on gravity that the lower tooth of tooth harrow is inserted in the slag thing that has been sucked; Hold together to pick up the slag thing with tooth harrow meshing up and down then, this moment, the absorption of slag thing was very tight, though lower tooth can inject a bit; But it is more thereby stress surface is bigger because of the number of teeth; So meshing on adding the same folder of two crown length is less than the slag thing when holding together, and this kind tooth harrow formula trash rake can only work under the situation that stops current (not generating electricity) at present, causes the economic loss in power station bigger.
Summary of the invention:
The purpose of the utility model patent is to overcome above-mentioned defective, provides a kind of both simple in structure, again can be at the tooth harrow formula trash rake under hydraulic turbine operate as normal (be under the generating state, the be commonly called as moving water state) situation.
The technical scheme of the utility model; A kind of tooth harrow formula trash rake; It is characterized in that described tooth harrow formula trash rake comprises walking track, walking mechanism, winding plant, hoist rope, switching wire rope and the grab bucket of tooth harrow formula; This walking track is installed in and moves on the stand; Walking mechanism is installed on the walking track, and winding plant is installed on the walking mechanism, is connected with the switching wire rope through hoist rope between the grab bucket of winding plant and tooth harrow formula;
Described tooth harrow formula grab bucket comprises the tooth harrow installing rack, goes up tooth, lower tooth, fixed bar, directive wheel, top sheave and lower sheave, sets gradually top sheave and lower sheave on the tooth harrow installing rack;
Described upward tooth is an arc grid grab type structure, and lower tooth is a barrier formula structure; It is logical to go up tooth
Cross two motion bars and be connected with the tooth harrow installing rack, lower tooth is connected with the tooth harrow installing rack through two fixed bars, and two fixed bars are provided with directive wheel.
The automatically controlled part of the utility model is used for realizing that overload protection, control open and close height, and operation can manual, remote control, can pass through the PLC full automatic working.
The utility model carries traveling mechanism, promptly on chassis or portable stand, a walking track is installed, and can adopt the special-purpose steel rope system that opens and closes to realize that tooth harrow formula grab bucket slusher opens and closes at upstream and downstream direction or left and right banks direction operation.When putting down the switching wire rope, tooth is opened in the grab bucket of tooth harrow formula, when putting down boom hoist cable; The grab bucket of tooth harrow formula is sunk, and lower tooth touches at the end (top that the slag thing is heaped), makes tooth touch at the end (top that the slag thing is heaped) operation of traveling mechanism upstream direction; Open and close when volume poplar device promotes that wire rope is pulled on, lower sheave and drive tooth; Lower tooth along directive wheel from down and on, close up simultaneously, fish for and grasp the slag thing., as long as winding plant lifting force greater than the absorption affinity of slag thing, just can grasp slag thing go round and begin again slag thing cleaned out through calculating this moment.
This trash rake is novel in design, simple in structure, improve the operating efficiency of generating set greatly,
Adopt the special-purpose steel rope system that opens and closes to realize that tooth harrow formula grab bucket slusher opens and closes; Overcome the shortcoming that traditional trash rake leans on gravity closing, also overcome the fluid pressure type slusher cause break or with breastwork, the friction of trashrack face, this trash rake can be worked in the porous water inlet.
