The specific embodiment
Describe concrete structure of the present utility model below with reference to accompanying drawings in detail:
A kind of three grades of lifting mode straddle carriers shown in accompanying drawing 1～4, comprise the vehicle frame 1 that is positioned at the bottom, the and arranged on left and right sides of vehicle frame is respectively arranged with a column 2, the suspender 4 that is used to transport goods, is used to install the piston shoes arm 5 of suspender 4 and the hydraulic actuating cylinder 11 that hoists, the both ends of piston shoes arm 5 are installed with piston shoes 3 respectively, and piston shoes 3 can be along being arranged on the column 2 that column 2 slides up and down.Every root post 2 is telescopic three grades of pillar constructions, and two columns 2 fixedly stand in respectively on four angles of vehicle frame 1.Every root post 2 comprises that the one-level column 6 of captiveing joint with vehicle frame 1, secondary column 7, the slip that is nested in the one-level column 6 of sliding are nested in three grades of columns 8 in the secondary column 7.The section of one-level column 6 and secondary column 7 is a rectangular cross section, and the section of three grades of columns 8 is the I shape section.Wherein, a pair of one-level column 6 that is positioned at the same side is connected by one first crossbeam 13, and two secondary columns 7 are connected by one second crossbeam 14.
The hydraulic actuating cylinder 11 that hoists is used to control 2 liftings of telescopic column, and it is furnished with motor 12, and the hydraulic actuating cylinder 11 that hoists is hingedly mounted between one-level column 6 and the secondary column 7.The cylinder sleeve and first crossbeam 13 of hydraulic actuating cylinder 11 of hoisting fixes (or be fixed on the one-level column 6 or be fixedly mounted on the vehicle frame 1), and the piston rod of the hydraulic actuating cylinder 11 that hoists and second crossbeam 14 fix (or being fixed on the secondary column 7).
Below the concrete method of operation of the present utility model down of setting forth:
As shown in Figure 4, straddle carrier is when zero load, column 2 is in contraction state, when straddle carrier when needs carry out the stacking operation, at first, the piston rod that motor 12 drives the hydraulic actuating cylinder 11 that hoists upwards rises, and the piston rod of the hydraulic actuating cylinder 11 that hoists drives secondary column 7 and upwards rises with respect to one-level column 6, simultaneously, first movable pulley 15 that is installed on second crossbeam 13 drives the upwards rising of two times of speed that three grades of columns 8 move with the piston rod with respect to the hydraulic actuating cylinder 11 that hoists; Simultaneously, second movable pulley 9 that is installed in three grades of column 8 tops drives piston shoes arm 5 and upwards rises with the Quad Data Rate that the piston rod with respect to the hydraulic actuating cylinder 11 that hoists moves, when the piston rod of the hydraulic actuating cylinder 11 that hoists rises to topmost, column 2 is in the state of full extension, the suspender 4 that is installed on this moment on the piston shoes arm 5 can be by the goods of the superiors' height, as shown in Figure 5.After suspender 4 was sling goods, the hydraulic actuating cylinder 11 decline certain height that hoist made the straddle carrier can be with pulsation-free mode shipping goods.
Otherwise when straddle carrier need shrink, then can carry out on the contrary, no longer be described inferior by above-mentioned mode.
Therefore this lifting straddle carrier has following innovative point:
(a), heap case height height (heap 4 crosses 5)
Because this car adopted telescopic post, can pile 4 when making the column of straddle carrier be raised to most significant bit and cross 5 operations, double than traditional straddle carrier service efficiency.
(b), level conveyor is flexibly moving
Fall when the next when telescopic boom, the car load height descends a lot.Make that like this straddle carrier oad is smaller and more exquisite, horizontal transport operation is convenient flexibly, has improved the stability of complete machine greatly.
(c), lifting mechanism is simple
Hoist and adopt the form of rope traction suspender.By the lifting of hydraulic actuating cylinder extension and contraction control column, walk around the action that hoists that the assembly pulley that is fixed on the column is finished suspender by steel rope more earlier.One cover lifting mechanism is controlled whole action, and cost reduces greatly, and maintaining is convenient.
The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the present utility model.
