Brief description
In order to be illustrated more clearly that this utility model or technical scheme of the prior art, below will be to embodiment or existing In technology description the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description be this practicality newly Some embodiments of type, for those of ordinary skill in the art, on the premise of not paying creative work, can also root Obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is supporting leg schematic diagram of the present utility model.
Specific embodiment
In order that above-mentioned purpose of the present utility model, feature and advantage can become apparent from understandable, right below in conjunction with the accompanying drawings Specific embodiment of the present utility model is described in detail.
Elaborate detail in order to fully understand this utility model in the following description.But this utility model can To be implemented different from alternate manner described here with multiple, those skilled in the art can be without prejudice to this utility model intension In the case of do similar popularization.Therefore this utility model is not limited by following public specific embodiment.
As shown in figure 1, in order to improve the reliability of force feedback detection, safety, stability after supporting leg lands.This practicality New provide a kind of supporting leg, including outrigger arm 1, support oil cylinder 2, sensor.Movable plate 3, supporting leg are provided with outrigger arm 1 Oil cylinder 2 is fixed on movable plate 3.Baffle plate 4 is provided with outrigger arm 1, movable plate 3 is located at below baffle plate 4, is used for placing restrictions on movement Plate 3 continues to move up.Connecting rod bores is offered on movable plate 3 and baffle plate 4, bolt 7 passes through the company of movable plate 3 and baffle plate 4 Extension bar hole, nut of screwing on bolt 7.In addition, bolt 7 and nut can also be replaced using other connecting rods, such as:Connecting rod Two ends are big, middle little.
In the present embodiment, sensor is travel switch 5, is provided with detection bar 6, travel switch 5 is located on movable plate 3 Above detection bar 6.
When support oil cylinder 2 is not supported on ground, support oil cylinder 2 does not land stress, and movable plate 3 and support oil cylinder 2 are in weight In the presence of power, it is in lower position (as shown in Figure 1), bolt 7 and nut start stress.The upper surface of movable plate 3 and baffle plate 4 Lower surface between formed apart from L for movable plate the amount of movement about 3, amount of movement can by tighten or unscrew nut adjust Section.Amount of movement can be touched stroke according to travel switch 5 and determine.Now, because detection bar 6 does not touch travel switch 5, stroke Switch 5 attonitys, travel switch 5 is closed.
When support oil cylinder 2 supports on the ground, support oil cylinder 2 lands stress, and movable plate 3 and support oil cylinder 2 are on ground Under counteracting force, movable plate 3 and support oil cylinder 2 move down, and movable plate 3 is resisted against limited on baffle plate 4.Now, detection bar 6 Also touching travel switch 5, travel switch 5 action are moved up therewith, travel switch 5 is in closure state.The pass of travel switch 5 Close and closure signal, can reflect supporting leg land after stressing conditions.
This utility model improves the reliability of force feedback detection, safety, stability after supporting leg lands.Effectively prevent Aerial work platform tipping condition occurs.Ensure operator's processing safety.
In order to prevent support oil cylinder 2 top beat from exceeding travel switch 5 detection range, what raising supporting leg detected further can By property, safety, stability, in further technical scheme, the cylinder barrel lower end of support oil cylinder 2 is connected with movable plate 3, stroke Switch 5 is located at the cylinder barrel lower end of support oil cylinder 2.Because the cylinder barrel lower end beat of support oil cylinder is less, without departing from travel switch 5 Detection range.Thus improve the reliability of supporting leg detection, safety, stability.
In order to adjust detection bar 6 further with travel switch 5 touching stroke so that travel switch 5 action moment is more accurate, Improve the precision of force feedback detection after supporting leg lands.Screwed hole is offered on movable plate 3, detection bar 6 one end is provided with spiral shell Stricture of vagina section, thread segment is coordinated with screwed hole.By unscrewing and tightening detection bar 6, to adjust between detection bar 6 and travel switch 5 Distance is so that travel switch 5 action moment is more accurate.
In order to adjust detection bar 6 further with travel switch 5 touching stroke so that travel switch 5 action moment is more accurate, Improve the precision of force feedback detection after supporting leg lands.Detection bar 6 other end is provided with true plate, touch panel cross-sectional area is more than inspection The cross-sectional area of measuring staff 6.After support oil cylinder 2 lands stress, there is beat, because touch panel cross-sectional area is big, without departing from row Cheng Kaiguan 5 detection range.Detection reliability, safety, stability are this improves.
This utility model additionally provides second embodiment (not shown):Sensor is pressure transducer, pressure Sensor is provided with baffle plate 4, and when support oil cylinder 2 is supported on ground, movable plate 3 is resisted against on baffle plate 4, and pressure transducer can The pressure to baffle plate 4 for the movable plate 3 is detected, to feed back stressing conditions after supporting leg lands.When pressure transducer detects pressure letter Number when, illustrate that movable plate 3 moves up spacing by baffle plate 4, movable plate 3 is in upper limit position.The program not only can detect Movable plate 3 is in position signalling, and stress size after supporting leg lands can be detected.The program is optimum embodiment scheme, Detection reliability, safety, good stability.
This utility model additionally provides the third optimum embodiment scheme (not shown):Sensor is range finding sensing Device, distance between distance measuring sensor detection baffle plate 4 and movable plate 3, when the distance between baffle plate 4 and movable plate 3 are for 0, also When being that movable plate 3 is resisted against on baffle plate 4, illustrate supporting leg land after stress.The program equally can improve detection reliability, safety Property, move qualitative.
This utility model additionally provides the 4th kind of optimum embodiment scheme (not shown):Sensor is travel switch 5, The cylinder barrel of support oil cylinder 2 is provided with contact, when movable plate 3 is moved upwards up to precalculated position, contact can be touched stroke and open Close 5 actions.The program equally can improve detection reliability, safety, move qualitative.
In addition, this utility model additionally provides a kind of aerial work platform including above-mentioned supporting leg.
Specific case used herein is set forth to principle of the present utility model and embodiment, above example Explanation be only intended to help understand core concept of the present utility model.It should be pointed out that the ordinary skill for the art For personnel, on the premise of without departing from this utility model principle, this utility model can also be carried out with some improvement and modify, These improve and modification also falls in this utility model scope of the claims.
