The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 2, be the structural representation of an embodiment of the collapsible foot-operated device of the utility model.In the present embodiment, collapsible foot-operated device comprises the pedal support of the turntable inwall that is fixed on crawler crane and the stretcher that is flexibly connected by bearing pin and described pedal support, and described stretcher rotates preset angles with respect to described pedal support and realizes open mode (as shown in Figure 3) and folded state (as shown in Figure 4).
Pedal support comprise two with the fixing supporting blades 2 of turntable inwall, two supporting blades 2 that bearing pin 4 is arranged in pedal support are the upper axis hole 7 that arranges respectively, the two ends of bearing pin 4 are by spring cotter 6 restriction bearing pin 4 movements in the axial direction.
Between two supporting blades 2 of pedal support, can also be provided with the positioning plate 8 of the rotational angle of restrict foot pedal.This positioning plate 8 and bearing pin 4 stop that jointly stretcher turns to certain angle (for example downward-sloping angle), to avoid the staff to skid or to step on sky.As required, can form such pedal support by the mode with supporting blade and positioning plate welding, also can two supporting blades and the described positioning plate of pedal support is integrally manufactured.
Stretcher comprises U-shaped dividing plate 3, and the both sides of this U-shaped dividing plate 3 are provided with groove 9, and bearing pin 4 is arranged in the groove 9 of U-shaped dividing plate 3 both sides, and owing to bearing pin 4 can move by the length direction along groove in groove 9, so stretcher can move predeterminable range with respect to bearing pin.Because stretcher can rotate preset angles with respect to pedal support, also can mobile predeterminable range, therefore can make whole collapsible foot-operated device be retracted to the state of turntable inwall, greatly reduced its shared operational space.
The bottom of U-shaped dividing plate 3 is the weight of carrying the staff, can be designed to slab construction, also can be designed to by a plurality of long narrow lamellar body 5(as shown in Figure 2) structure that consists of, for anti-skidding, can be set as serrated-surface in the bottom of U-shaped dividing plate 3, with increasing friction force.
Turntable at crawler crane is inner, and collapsible foot-operated device can be equipped with in the position at the right front of turntable inboard, right the place ahead, left back and/or left rear collapsible foot-operated device.Shown in Fig. 5,6, collapsible foot-operated device generally can be arranged in the position of the inboard right front A of turntable, right the place ahead B, left back C, left rear D.The advantage that arranges at these several places is: 1. the right front is to arrange rotary reducer, the place of elevator and hydraulic pressure electric elements hoists, motor and the hydraulic tubing of elevator of hoisting simultaneously is in the left side, can make the operational space larger therefore collapsible foot-operated device is arranged on the right side, convenient for maintaining.2. right position is the place of arranging hydraulic oil radiator and hydraulic reservoir, and radiator lies in below the collapsible foot-operated device, and hydraulic reservoir is in collapsible foot-operated device back, and insert space is very large, is fit to arrange collapsible foot-operated device.3. the left back is the place of arranging luffing elevator and hydraulic pressure, electric elements, and motor and the hydraulic tubing of luffing elevator are on the right side simultaneously, can make the operational space larger therefore collapsible foot-operated device is arranged in the left side, convenient for maintaining.4. left position is the place of arranging driving engine and oil pump, driving engine (placing before and after the driving engine) is put in collapsible foot-operated device front, driving engine back connecting fluid pressure oil pump, the position of collapsible foot-operated device is in the hydraulic oil pump left side, insert space is relatively large, convenient maintenance and maintenance to driving engine and hydraulic reservoir.
Thus, the crawler crane that aforementioned collapsible foot-operated device has been installed also can correspondingly make the staff pass in and out easily turntable inside, and enough operational spaces are arranged, and is convenient to the staff and operates.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
