The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Referring to Fig. 1 to Fig. 4, the utility model provides a kind of rotatable material elevator, is mainly used in the turnover delivery of multiple benches interstation material in the guideway vehicle fitter's shop.Mainly by bottom support 10, rotating table 9, lifting mechanism, loading stage 4, load wagon 2, material carrying case 1 form.This material elevator can be used for being equipped with the multiple benches platform of standard-gauge rail track, material elevator platform interdigit material transportation, and rail-guided load wagon 2 loaded material carrying cases 1 carry out individual layer platform interdigit material transportation.
Bottom support 10 has system control platform (not marking in the drawings), places undergroundly, mainly comprises hydraulic power control system and motor-driven control system.Motor transmission mechanism comprises motor 13, retarder 14, one-level gear 12 and the secondary gear 11 that connects successively, one-level gear 12 and secondary gear 11 are intermeshing, one-level gear 12 and secondary gear 11 are positioned at the top of bottom support 10,9 coaxial connections of rotating table of secondary gear 11 and disc type, one-level gear 12 is connected with the output shaft of retarder 14, and retarder 14 is connected with the output shaft of motor 13.By retarder 14 with the power transmission of motor 13 to one-level gear 12, one-level gear 12 and secondary gear 11 engagements, again slow down, with power transmission to rotating table 9, rotating table 9 is steadily rotated, and 10 of rotating table 9 bottoms and bottom supports are by the spherical roller support and connection, and spherical roller can reduce friction and rotational resistance, guarantee the rotating table smooth running, and carry out rotating table 9 and support.
Motor 13 is stepping motor, and the motor stepping is sent step instruction take rotating table 9 90-degree rotation angles as unit, i.e. 90-degree rotation is finished the rotary work of rotating table 9, guarantees can finish smoothly lifting after rotating table 9 rotations.
Lifting mechanism is crossing type lifting apparatus, cuts yoke 5 and two lifting drive hydraulic actuating cylinders 15 form by two X-types, realizes that twin-tub drives.Each X-type is cut yoke 5 by cutting fork member 18 in multistage and the multistage outer fork member 19 of cutting is cross-linked and consists of, in cut fork member 18 and cut outward between the fork member 19 and connect by hinge bolt 6 and the nut 7 of being connected.In the present embodiment, X-type is cut fork device and is interconnected and form by cutting fork member 18 in the two-stage and cutting fork member 19 outward, can according to the requirement for height of required rising, cut fork member 18 in the increase and decrease and cut the quantity of pitching member 19 outward.
The yokes 5 of cutting at different levels are cut member 18 and are cut member 19 outward and be interconnected to form by interior, the X-type of level of the end cut yoke 5 in cut fork member 18 bottoms and carry out hinged fixing with rotating table 9, the outer attached rotation roller 16 in fork member 19 bottoms of cutting of level of the end, in the roller guide groove 8 that rotation roller 16 inserts on rotating table 9 end faces, and can be in the 8 interior rollings of roller guide groove, the realization X-type is cut the plane rolling constraint of yoke 5 and rotating table 9, regulates the adjustable height of whole material bay-lift.
Two lifting drive hydraulic actuating cylinders 15 are arranged on X-type and cut outside the first order of yoke 5 bottommosts and the second stage and cut between the fork member 19, and lifting drive hydraulic actuating cylinder 15 is realized lifting action by the hydraulic power control system input power that is positioned at below the bottom support 10.
The X-type at lifting mechanism top is cut yoke 5 and is captiveed joint with the bottom of loading stage 4, can place the load wagon 2 with wheel 20 on loading stage 4 end faces, offer loading stage track 17 on loading stage 4 end faces, this loading stage track 17 is the same with track on the bench board to be the rail track of standard, when loading stage 4 reaches the height of bench board position, propelling loading car 2 moves on the bench board along loading stage track 17 always, and then finishes the transportation of material.Four wheel locating chucking tools 3 are installed on the loading stage track 17, are used for the fixedly wheel 20 of load wagon 2, prevent from rotatablely moving or during dipping and heaving load wagon 2 be moved, guarantee safe lifting or rotation.After lifting is finished, open wheel locating chucking tools 3, load wagon 2 is pushed into corresponding station carries out the material unloading.In the present embodiment; load wagon 2 is provided with 4 wheels 20; wheel locating chucking tools 3 also is made as 4; in the actual conditions; can be according to real needs; the quantity of wheel locating chucking tools 3 can be identical with wheel 20 numbers or its two times, namely is equipped with wheel locating chucking tools 3 at the two ends of wheel 20, strengthens protection strength.
The material carrying case 1 that is complementary can be placed in load wagon 2 tops, and load wagon 2 end faces are provided with a pair of set pin at least, and with pin-and-hole, set pin inserts in the pin-and-hole on the relevant position, material carrying case 1 bottom, is used for carrying out the accurate location of load wagon 2 and material carrying case 1.
Each grade working table position (not marking in the drawings) all is equipped with height limitator, the one-sided limit induction device that is equipped with at loading stage 4, after loading stage 4 rises to required arrival platform position, height limitator sends spacing instruction, the limit induction device receives instruction, stop lifting, finish the positioned-lifting process.By the height limitator braking, the adjustable height of control elevator is behind the platform position of selecting to confirm to reach, than its low height limitator autoshutdown.
Realized the lifting process of whole elevator by the X-type crossing type lifting apparatus of double shear twin-tub, load wagon 2 bottoms are provided with wheel 20, the convenient promotion, integral structure is simple, easy to operate, and be connected with the rotating table 9 that stepping motor 13 is controlled in the bottom of X-type crossing type lifting apparatus, and be rotated with 90 angles of spending, can adapt to each angle work-table material supply needs; And by height limitator realization lifting braking, wheel locating chucking tools 3 fixes load wagon 2 in lifting or rotary course, by locating dowel pin the material load wagon is carried out accurate positioning action safety, improves equipment dependability.
Below only be specific embodiments more of the present utility model; above-mentioned concrete structure can not be interpreted as restriction of the present utility model; in fact; specific embodiment of the utility model has a variety of, and every insubstantial modifications of in the utility model design it being made is all implemented in protection domain of the present utility model.
