Abstract
The invention relates to a double-layer steel truss bolting rake tooth three-dimensional material rake of a scraper blade material taking machine, being applied to industry of material piling and taking machines. The whole device comprises a rake rack, rake teeth, round steel, a bolt pair, a first beam, a support, an oil cylinder support, a hand winding drum, and the like, wherein the material rake is designed to be in a double-layer steel truss three-dimensional structure; each beam of the material rake is made of different specifications of deformed steel; the rake teeth of the material rake are in bolt pair bolting structures; the tops of the rake teeth are connected in series by the round steel and are welded together; the bottom of the material rake acts on a support beam through a roller device and is driven by a driving hydraulic cylinder, and the upper part thereof is connected with the hand winding drum or an electric block on a tower through a pulley block and a steel wire rope; the rake rack forms an angle of 38 degrees with the horizontal plane; and the rake rack of the material rake is in the double-layer steel truss three-dimensional structure, and the longitudinal vertical cross section of the rake rack is in a triangular structure. The material rake is designed to be in the double-layer steel truss three-dimensional structure, and therefore, the material rake has the advantages of light weight, high rigidity, small deformation and stable operation, overcomes the vibration on a bridge beam and the complete machine, which is caused by the insufficient rigidity of the material rake in the movement process and improves the stress state of the oil cylinder of a hydraulic driving system in the reciprocating movement of the material rake.
Description
Technical field:
The present invention relates in pre-homogenization yard, to carry out the large scale claw on the large-scale scraper reclaimer of material extracting operation, be used for the claw device that full section is got material.
Background technology:
At present, carry out the scraper reclaimer of material extracting operation in pre-homogenization yard, the effect of claw is with the material rake pine of stockpile section, is beneficial to scraping of scraper plate and gets.At present, along with the development of industries such as building materials, coal, electric power, the stacker-reclaimer that is used in operation in the pre-homogenization yard also maximizes day by day, is used for full section thereupon on the scraper reclaimer and gets the claw device of material and also strengthen.And large-scale scraper reclaimer claw hydraulically powered big claw, the little stroke structures of adopting more.Conventional claw device is the plane triangle skeleton, is welded on the main framing by shaped steel assembly welding stirrup and rake teeth and forms; Or scrape as the accessory structure of skeleton with steel rope and to get material.This planar structure rigidity is relatively poor, and when claw strengthened, the deadweight of claw strengthened, and the deflection of claw will be very big.The distortion of claw brings bumpy motion, finally brings the vibrations of complete machine.Rake teeth is connected with main body framework by welding manner in addition, is not easy to change.For this reason, increase the rigidity of reclaimer claw device, reduce deadweight and deflection thereof, and be convenient to safeguard, will become the problem to be solved in the present invention.Therefore, develop the scraper reclaimer clad steel purlin three-dimensional claw of bolt rake teeth is new problem anxious to be solved always.
Summary of the invention:
The object of the present invention is to provide a kind of in light weightly, good rigidly, distortion be little, operate steadily, that consumable accessory is changed is convenient, be beneficial to maintenance the three-dimensional claw of scraper reclaimer clad steel purlin bolt rake teeth.
The object of the present invention is achieved like this: the three-dimensional claw of a kind of scraper reclaimer clad steel purlin bolt rake teeth, whole device is by the rake frame, rake teeth, round steel, the bolt pair, first beam, bearing, cylinder support, second beam, the 3rd beam, the 4th beam, the 5th beam, roller devices, drive hydraulic actuating cylinder, assembly pulley, steel rope, pylon, hand reel is formed, clad steel purlin spatial structure is adopted in the claw design, each beam of claw adopts the deformed steel of different size to make, the claw rake teeth adopts the secondary bolt structure of bolt, the rake teeth end with the round steel series welding together, the claw bottom acts on the support beam by roller devices, by driving Driven by Hydraulic Cylinder, assembly pulley is passed through on top, hand reel or electric block are connected on steel rope and the pylon, and the rake frame becomes 38 to spend angles with level; The rake frame of claw has adopted clad steel purlin spatial structure, its vertical vertical section is a triangular structure, first beam is provided with the bearing and the hydraulically powered cylinder support of claw of claw walking roller, second beam is provided with the assembly pulley bearing, this assembly pulley and steel rope, hand reel or electric block are formed the hoisting mechanism of regulating the claw angle, and the 3rd beam, the 4th beam are connected with the 5th beam; Rake teeth is made with round steel, each rake teeth by two groups of hook-shaped bolts and nut retainer be connected on the rake frame on, the rake teeth end on each beam with same round steel series welding together, round steel plays stabilization to rake teeth, the while round steel also play the loose material effect of scraping; The flowing end face that rake teeth bottom the walking claw of end carriage and round steel enter stockpile, claw is done the scraper motion of horizontal direction simultaneously under the actuating device effect, with material rake pine, the material at top rolls to the bottom simultaneously, make the main scraper plate function of bridge bottom obtain the material that claw scrapes smoothly, and, be discharged at last on the discharging sealing-tape machine along with the scraper of scraper plate machine is moved.
Main points of the present invention are its structure and principle of work.Its principle of work is, clad steel purlin spatial structure has been adopted in the claw design, and the claw frame adopts the deformed steel of different size to make, and the claw rake teeth adopts the bolt structure.The rake teeth end with the round steel series welding together.The claw bottom acts on the support beam by roller devices, top is connected by hand reel on assembly pulley, steel rope and the pylon or electric block, become 38 degree angles with the rake teeth of the walking claw bottom of end carriage and the flowing end face that round steel enters stockpile with level, claw is done the scraper motion of horizontal direction simultaneously under the actuating device effect, with material rake pine, the material at top rolls to the bottom simultaneously, make the main scraper plate function of bridge bottom obtain the material that claw scrapes smoothly, and, be discharged at last on the discharging sealing-tape machine along with the scraper of scraper plate machine is moved.
The three-dimensional claw of scraper reclaimer clad steel purlin bolt rake teeth compared with prior art, have the claw design and adopted clad steel purlin spatial structure, in light weight, good rigidly, the distortion little, operate steadily, overcome because the bridge that the rigidity deficiency of claw causes in motion process and the vibration of complete machine, improve the force-bearing situation of claw fluid power system oil cylinder in crank motion, the claw rake teeth adopts the bolt structure, it is convenient to change, be beneficial to the advantages such as working service of equipment, will be widely used in the stacker-reclaimer industry.
