Description
Technical Field
The utility model relates to an automatic flexible car toe guard that is suitable for shallow pit.
Background
A toe guard is arranged under a car sill of the elevator to prevent personal injury caused by shearing when a front door is opened before the car is leveled or the car sill is higher than a landing door sill after leveling. The pit depth can not reach the normal elevator depth for various reasons in some old buildings, and when the car descends to the bottom layer, the car toe guard can strike the pit ground, so that the service life of the toe guard is influenced, and the elevator can not be normally accepted and operated.
SUMMERY OF THE UTILITY MODEL
In view of the not enough of prior art, the utility model aims to solve the technical problem that an automatic flexible car toe guard is provided, not only simple structure, convenient high efficiency moreover.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides an automatic flexible car toe guard, includes the vertical fixed plate of installing on the car sill, the vertical expansion plate that is equipped with on the fixed plate, expansion plate through slide rail and fixed plate sliding fit, the expansion plate carries out up-and-down concertina movement through the electric motor mechanism drive.
Preferably, the slide rail sets up respectively between the left side of expansion plate and fixed plate, between the right side of expansion plate and fixed plate, and the slide rail adopts the steel ball formula slide rail that the drawer was used, and has the metal slide rail of three sections.
Preferably, the electric mechanism comprises a first connecting rod, a second connecting rod and an electric push rod, the outer end of the first connecting rod is hinged to the inner side face of the expansion plate, the inner end of the first connecting rod is hinged to the lower end of the second connecting rod, the upper end of the second connecting rod is hinged to the outer bottom face of the car, a movable arm of the electric push rod is hinged to the non-end portion of the first connecting rod downwards, and the top of the electric push rod is hinged to the outer bottom face of the car.
Preferably, the outer bottom surface of car has linked firmly the dead lever, and second connecting rod upper end, electric putter top all articulate on this dead lever.
Preferably, the swing amplitude of the electric push rod on the vertical plane along the top hinged point is +/-5 degrees, and the swing amplitude of the second connecting rod on the vertical plane along the upper hinged point is +/-5 degrees.
Compared with the prior art, the utility model discloses following beneficial effect has: this automatic flexible car toeguard's simple structure, toeguard comprise fixed plate and expansion plate, and the expansion plate is scalable, expandes when needing, contracts when the pit, has solved because of the unable technical bottleneck problem that changes toeguard and can strike pit ground of former shaft way low pit building height, not only can be applied to old building and more renew the ladder, also can be applied to old building and install the elevator additional to and newly-built house and office building etc..
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Drawings
Fig. 1 is a schematic view of a first operating state of the embodiment of the present invention.
Fig. 2 is a schematic view of a working state of the embodiment of the present invention.
Detailed Description
In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1-2, an automatic telescopic car toe guard comprises a fixed plate 2 vertically installed on a sill of a car 1, a telescopic plate 3 is vertically arranged on the fixed plate, the telescopic plate is in sliding fit with the fixed plate through a sliding rail 4, and the telescopic plate is driven by an electric mechanism to perform up-and-down telescopic motion.
In the embodiment of the utility model, the slide rails are respectively arranged between the left sides of the expansion plate and the fixed plate and between the right sides of the expansion plate and the fixed plate, the slide rails are steel ball type slide rails for drawers and are provided with three sections of metal slide rails, the expansion plate is arranged on the third section of metal slide rail, and a sliding pair vertical to the horizontal plane is arranged between the expansion plate and the fixed plate; the steel ball type sliding rail is the prior art, and the installation principle of the steel ball type sliding rail is the same as that of the steel ball type sliding rail when the steel ball type sliding rail is applied to the side face of a drawer.
The embodiment of the utility model provides an in, electric mechanism includes first connecting rod 5, second connecting rod 6, electric putter 7, and first connecting rod outer end articulates at the medial surface of expansion plate, and first connecting rod inner is articulated with second connecting rod lower extreme, and second connecting rod upper end articulates in the outer bottom surface of car, and electric putter's swing arm articulates the non-tip at first connecting rod down, and electric putter's top articulates in the outer bottom surface of car.
The embodiment of the utility model provides an in, the outer bottom surface of car has linked firmly dead lever 8, and second connecting rod upper end, electric putter top all articulate on this dead lever.
The embodiment of the utility model provides an in, electric putter is for 5 along its top pin joint swing range on vertical plane, and the second connecting rod is 5 along its upper end pin joint swing range on vertical plane, and the design can guarantee that the folding overall process electric putter swing range of shrinking is minimum about the toe guard like this, and the atress is most reasonable, and each pole moves freely, does not have the card and rolls the phenomenon.
The working principle of the automatic telescopic lift car toe guard is as follows: when the elevator leaves the bottom layer, the electric push rod extends out of the movable arm, the telescopic plate slides downwards along the sliding rail, the electric push rod, the first connecting rod and the second connecting rod swing along the hinged hinge pin respectively, after the movable arm of the electric push rod touches the limit switch, the movable arm stops moving, and the foot guard plate of the telescopic car is in an unfolded state. When the elevator is about to reach the bottom layer, the electric push rod retracts into the movable arm, the telescopic plate ascends along the sliding rail, the electric push rod, the first connecting rod and the second connecting rod swing along the hinged hinge pins respectively, after the movable arm of the electric push rod touches the limit switch, the movable arm stops moving, and the foot guard plate of the telescopic elevator car is in a folding (contracting) state. The problem of because of the unable technical bottleneck that changes baseboard and can strike pit ground of low pit building height of former shaft way is solved, both improved collapsible folding baseboard life, eliminated again because of the noise that the collision produced and take the discomfort.
The present invention is not limited to the above preferred embodiments, and any person can obtain other various forms of the automatic retractable car toe guard according to the teaching of the present invention. All the equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
