Abstract
The utility model discloses a locking mechanism of an operation device, which comprises an operation rod, a limit plate mechanism and a limit plate locking mechanism. The limit plate mechanism comprises a limit plate and a base; the base is fixed onto a floor of a cab on the outer side of the operation rod; the limit plate is a fork-shaped structure; one end of the limit plate is hinged to the upper end of the base through a hinge mechanism; when the operation rod is locked, the operation rod is positioned in a fork opening at the other end of the limit plate; the limit plate locking mechanism comprises an inner locking plate and an outer locking plate which are respectively fixedly arranged on the inner side and the outer side of the base; at least one magnet is embedded inside the locking plate; and the limit plate is positioned on the upper side of the magnet. The locking mechanism has simple structure, is convenient in use and installation, and is adaptable to locking engineer mechanical operation rods. Whether the limit plate is in locking state of overturning 180 degrees or in unlocking state of returning to an initial position, the limit plate is reliably actuated and fixed to the upper end of the base in order to ensure normal work of the operation rod.
Description
Technical field
The utility model relates to a kind of safety feature of engineering machinery operating rod, especially a kind of when being used to stop lever locked make its safety feature that can not at will pull, belong to technical field of engineering machinery.
Background technology
The catanator of engineering machinery adopts the electromagnetic clutch device lever locked to carry out security control more, but electromagnetic clutch device is only applicable to the catanator of hydraulic control lever, the mechanical linkage catanator adopts the pattern of multiple lever locked such as locking of hydraulic stopper oil cylinder or mechanical linkage stop locking, to satisfy the requirement of clauses such as security legislation.Owing to be subjected to the restriction of many conditions such as the pilothouse arrangement space of engineering machinery is narrow and small, opereating specification compactness, the locking mechanism of existing most of engineering machinery operating rods adopts the mechanical linkage locking, and this locking mechanism exists the defective that parts are many, mechanism is complicated, failure rate is high.
The utility model content
The purpose of this utility model is the defective that overcomes the locking mechanism of existing engineering machinery operating rod, and a kind of locking mechanism of simple in structure, engineering machinery operating rod that reliability is high is provided.
The utility model is achieved by the following technical programs:
A kind of locking mechanism of operating control, comprise operating rod, cab floor is passed in the lower end of described operating rod, and is hinged by lateral pin and leverage, also comprises limiting plate mechanism, described limiting plate mechanism comprises limiting plate, base, described base is fixed on the cab floor in the operating rod outside, and described limiting plate is a fork configuration, and an end of described limiting plate is hinged by linkage and base upper end, when operating rod was locked, this operating rod was positioned at the prong of the limiting plate other end.
The purpose of this utility model can also further realize by following technical measures.
The locking mechanism of aforesaid a kind of operating control, also comprise the limiting plate locking mechanism, described limiting plate locking mechanism comprises inside and outside lockplate, described inside and outside lockplate is fixedly installed on the interior outside of base respectively, described lockplate is embedded with at least one block of magnet, and described limiting plate is positioned at the magnet upside.
The utility model is simple in structure, use, easy for installation, is applicable to the locking of engineering machinery operating rod.During lever locked, with 180 ° of limiting plate upsets, make operating rod be positioned at the intersection end of fork-shaped plate, at this moment, operating rod can not be pulled front and back, has realized the rigid locking of operating rod, to reach the purpose that prevents maloperation.When operating rod unlocks, only need the limiting plate reverse flip is got back to the original position for 180 °.Because the interior outside of base upper end all is provided with the lockplate that has embedded magnet, no matter limiting plate is the lock-out state that is in 180 ° of upsets, still is in the state that unlocks of getting back to reference position, and all is fixed on the base upper end by adhesive reliably.Although it is violent to jolt during engineering machinery work, lockplate still can be in the lock state, and guarantees that operating rod can operate as normal.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the stereographic map of the utility model lock-out state;
Fig. 2 is the unlock stereographic map of state of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 2, present embodiment is used for the locking control of excavator pilothouse operating rod, and cab floor 2 is passed in the lower end of the operating rod 1 that is provided with in pairs, and is hinged by lateral pin and leverage 3.The limiting plate mechanism 4 of present embodiment comprises limiting plate 41, base 42, and described base 42 is a trench structure, and its bottom is fixed on the cab floor 2 in operating rod 1 outside by securing member.Limiting plate 41 is a fork configuration, and an end of limiting plate 41 is hinged by linkage 43 and base 42 upper ends.When needing lever locked 1, with 180 ° of limiting plate 41 upsets, it is limited in the prong 411 of limiting plate 41, at this moment, operating rod 1 can not be pulled front and back, can be used for preventing maloperation, has guaranteed that excavator is in the safety locking state when stopping.
In order to make limiting plate 41 can both be in locking, the utility model also is provided with limiting plate locking mechanism 5, and this limiting plate locking mechanism 5 comprises interior lockplate 51, outer lockplate 52.Interior lockplate 51, the outer lockplate 52 of present embodiment are L shaped, the vertical edges of interior lockplate 51, outer lockplate 52 is fixedly installed on the interior outside of base 42 stiles respectively, be embedded with 2 blocks of magnet 53 respectively in the interior lockplate 51 of present embodiment and the horizontal sides of outer lockplate 52, the horizontal sides of interior lockplate 51, outer lockplate 52 is all played a supporting role to limiting plate 41.When 180 ° of lever locked 1 of limiting plate 41 upsets, prong 411 ends of limiting plate 41 are resisted against interior lockplate 51 upsides, and limiting plate 41 is remained on the state of lever locked 1 by 2 magnet 53 adhesives of interior lockplate 51 upsides; When limiting plate 41 when 180 ° of reverse flip are got back to the original position once more, prong 411 ends of limiting plate 41 are resisted against outer lockplate 52 upsides, and limiting plate 41 is by 2 magnet 53 adhesives of outer lockplate 52 upsides, the maintenance released state.Like this, no matter how engineering machinery jolted when working, limiting plate 41 remains at by magnet 53 attracting states.During shutdown, upset limiting plate 41 makes it by magnet 53 adhesives, thus lever locked 1.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
