Abstract
The utility model relates to an airplane assembly working ladder telescopic footboard. The airplane assembly working ladder telescopic footboard is composed of a T-shaped adapting piece, a flexible footboard and a slide rail, wherein the T-shaped adapting piece is mainly composed of a T-shaped plate, a rotating shaft and a wheel, the flexible footboard and the T-shaped adapting piece are tightly fixed through connecting bolts and round pins, the rotating shaft and the wheel are disposed on an erecting plate of the T-shaped plate, two ends of the rotating shaft are fixed on the erecting plate of the T-shaped plate through nuts and a gasket, and the slide rail is mounted below the footboard of a fixed working ladder. The airplane assembly working ladder telescopic footboard has the advantages of being flexible in sliding, saving both in time and effort, safe and reliable, and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of aircraft rigger and makes terraced telescopic pedal.
Background technology
Operating personnel must carry out work by special-purpose working stand in aircraft assembling, the riveted joint process, the working stand design whether rationally, handled easily personnel operation on the aircraft assembling jig is directly connected to operating personnel's life security and has influence on the efficiency of assembling of aircraft.Especially in some big-and-middle-sized complicated general assembly aircraft assembling jigs; Because the needs of riveted joint aircraft product; The formula working stand of being completely fixed can not satisfy action need, and the design of working stand also must be considered to increase movable part and assign to satisfy the production needs, but because the restriction in riveted joint space; Can not hinder the path of riveted joint product; Therefore must consider that also the part pedal can be movable during the design work ladder, promptly " move " as required at any time to the place that needs operation, after the operation also in time " disappearance " in order to avoid influence the riveting work at all the other positions of aircraft.
The working stand movable part of widespread wherein has a kind of design form to be in the industry at present: be designed to working stand movable part pedal telescopic; Two square steel promptly are installed as the slides in telescopic groove below fixing working stand pedal; With Active foot plate be connected the telescopic moving that is implemented in left and right directions in the slides in telescopic groove than the slightly little square steel in type hole in the employed square steel of telescopic chute, utilize stopping means to realize the fixing and spacing of Active foot plate.When operating personnel are riveted to the aircraft components corresponding site, successively Active foot plate is released from fixing working stand pedal bottom, carry out after putting in place spacing, treat that this section operation is accomplished after, Active foot plate is pushed the working stand bottom.
Above design form has the some shortcomings part in making and using: though telescopic structure can be hidden in working body pedal bottom; But be that moving between square steel and the square steel realizes stretching in use owing to what use; Frictional resistance is very big; Therefore need to use bigger power that it is released, also need personnel's cooperation, waste time and energy when adjusting the position and inserting spacer pin; Owing to will consider the stability of Active foot plate, all will connect the connecting rod lengthening of Active foot plate during design usually, under non-working condition, it is outside that connecting rod has partly stretched out working stand, formed potential safety hazard like this.
The utility model content
The utility model technical problem to be solved is: provide a kind of in aircraft assembling the telescopic pedal of working stand esy to use, safe and reliable.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme: a kind of aircraft rigger is made terraced telescopic pedal, and said telescopic pedal is made up of T-connecting piece, Active foot plate, slideway; Wherein T-connecting piece mainly is made up of T shape plate, turning cylinder, wheel; Active foot plate and T-connecting piece are closely fixing through connecting bolt, straight pin; T shape plate riser is installed turning cylinder and wheel, and T shape plate riser is fixed in through nut, packing ring in the turning cylinder two ends; Slideway is installed on steady job ladder pedal below.
The beneficial effect of the utility model is: slide flexibly, time saving and energy saving, safe and reliable and cheap, an operator just can easily realize flexible slippage, easily skids off during use, easily pushes after the use and realizes under the fixed working stand hiding, and is very convenient and practical.
Description of drawings
Fig. 1 is the elevation of a kind of specific embodiment of the utility model;
Fig. 2 is the sectional view of a kind of specific embodiment of the utility model shown in Figure 1 along center line;
Fig. 3 is the structural representation of T-connecting piece in the utility model;
Wherein, 1-T shape connector, 2-Active foot plate, 3-slideway, 4-steady job ladder framework, 5-steady job ladder pedal, 6-T shape plate, 7-turning cylinder, 8-wheel, 9-nut, 10-connecting bolt, 11-straight pin.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed description.
See also Fig. 1, Fig. 2, Fig. 3, the utility model aircraft rigger is made terraced telescopic pedal, and said telescopic pedal is made up of four T-connecting pieces 1, Active foot plate 2, slideway 3; Wherein T-connecting piece 1 mainly is made up of T shape plate 6, turning cylinder 7, wheel 8; Active foot plate 2 is closely fixing through connecting bolt 10, straight pin 11 with T-connecting piece 1; T shape plate riser is installed turning cylinder 7 and wheel 8, and T shape plate riser is fixed in through nut 9, packing ring in the turning cylinder two ends; Slideway 3 is installed on steady job ladder pedal 5 belows.
T shape panel material is generally iron and steel etc., and the Active foot plate material is generally plank.Be tightening security property, the steel plate that is connected with Active foot plate on the T shape plate can suitably be thickeied lengthening, and the longitudinal separation of T shape plate can suitably increase, and plays the effect of strengthening support.
When assembling the utility model, should be as shown in Figure 3, assemble T-connecting piece earlier.Then that Active foot plate 2 and T-connecting piece 1 is closely fixing through connecting bolt 10, straight pin 11.As shown in Figure 1, on fixed working stand framework 4, slideway 3 is set, slideway 3 can use channel-section steel etc.T-connecting piece 1 and Active foot plate 2 are placed on the slideway.As shown in Figure 2, utilize the flexible rotation of roller to drive Active foot plate and be implemented in the flexible sliding motion in the slideway, and at the desired location place limited block is set and inserts latch and carry out spacing and fixing.
