Toeguard should all be installed under car sill, the vertical protection height of toeguard should be not less than 0.75m.Present toeguard is mostly
The metal plate of one piece of one.Thus the problem of bringing be, in maintenance, when on the buffer that carriage is fully pressed against pit or stopping
When position is lower, toeguard may collide pit and be destroyed.On the other hand, monolithic plate body shielded area is big, is unfavorable for
Operation of the maintenance personal when overhauling cage bottom.Therefore, for existing toeguard in the presence of that can not adjust height, shielded area is big,
The problem of is required by height and is unfavorable for inspection operation for pit.
Utility model content
The purpose of the utility model is to provide the toe guard of elevator car of variable height.The utility model has adjustable
Highly, the characteristics of shielded area is small, requires operation low and convenient for safeguarding to pit.
The technical solution of the utility model includes: the toe guard of elevator car of variable height, including the upper plate body fixed with carriage, and with
The hinged lower body of upper plate body, is hinged with telescopic rod between lower body and cage bottom；The telescopic rod is arranged in pairs, and is stretched
Bar is equipped with the resilient pin of locking length of telescopic bar, and interlocking bar is connected between two resilient pins, and interlocking bar is equipped with steel
Cord；It further include the travel switch for two detection lower plate body positions being arranged on upper plate body or/and lower body.
In the toe guard of elevator car of variable height above-mentioned, the telescopic rod includes sliding sleeve and the core slided in sliding sleeve
Bar；The resilient pin includes the baffle being fixed on sliding sleeve, and the shank with spring, the core are equipped between sliding sleeve and baffle
Bar is equipped with the pin hole cooperated with shank.
In the toe guard of elevator car of variable height above-mentioned, the quantity of the travel switch is 2, one of to be arranged in upper plate
On body, and cooperate with telescopic rod；Another is arranged on lower body, and cooperates with upper plate body.
In the toe guard of elevator car of variable height above-mentioned, wire rope handling plate, the wirerope are additionally provided on the upper plate body
Across wire rope handling plate.
Compared with prior art, the utility model realizes that height adjusts by hinged plate body up and down, while by flexible
The structure of bar and resilient pin locks lower body, guarantees the stability of structural strength and locking, and the solution for passing through wirerope
Lock mode operates also very convenient.Moreover, the utility model detects the position of lower body by two travel switches,
It whether in place to monitor its expansion or collapsed state, hidden danger is reduced with this, improves safety.
Further, the telescopic rod of the utility model is the structure of the opposite sliding of sliding sleeve core bar, this structure with it is existing
Gas spring or the structure of scissor-type compare, one side structure is simple, and stability is good, is on the other hand easy to lock, and safety is good.
Further, switch setting two is formed, two states of toeguard are detected, improves safety.
Further, the hardened structure of wire rope handling can stop wirerope, provide conveniently for unlock operation.
To sum up, the utility model has adjustable height, and shielded area is small, requires low and convenient for safeguarding operation to pit
The characteristics of.Meanwhile the utility model also has the characteristics that easy to operate, safety is good.

Specific embodiment
Below with reference to embodiment, the utility model is described in further detail, but be not intended as to the utility model limit according to
According to.
Embodiment: the toe guard of elevator car of variable height, it is hinged including the upper plate body 10 fixed with carriage, and with upper plate body 10
Lower body 20, telescopic rod 30 is hinged between lower body 20 and cage bottom；The telescopic rod 30 is arranged in pairs, telescopic rod
30 are equipped with the resilient pin 40 of locking 30 length of telescopic rod, are connected with interlocking bar 51, interlocking bar between two resilient pins 40
51 are equipped with wirerope 50；It further include the stroke for two detection 20 positions of lower body being arranged on upper plate body 10 and lower body 20
Switch.
The telescopic rod 30 includes sliding sleeve 31 and the core bar 32 slided in sliding sleeve；The resilient pin 40 includes solid
The baffle 41 being scheduled on sliding sleeve 31, is equipped with the shank 43 with spring 42 between sliding sleeve 31 and baffle 41, the core bar 32 is equipped with
The pin hole 33 cooperated with shank 43.
Two travel switches, it is one of to be arranged on upper plate body 10, and cooperate with telescopic rod 30；Another sets
It sets on lower body 20, and cooperates with upper plate body 10.
Wire rope handling plate 52 is additionally provided on the upper plate body 10, the wirerope 50 passes through wire rope handling plate 52.
Working principle:
As shown in Figure 1, two travel switches of note are respectively that travel switch 61 is unfolded and packs up travel switch 62.
As shown in Figure 1, toeguard is in unfolded state.At this point, telescopic rod 30 extends completely, resilient pin 40 passes through core bar
32 upper pin holes 33 lock telescopic rod 30.Meanwhile the telescopic rod 30 extended completely can encounter the expansion positioned at upper plate body 10
Travel switch 61, elevator control panel is by the reference signal run to induction signal, the signal as elevator.Elevator control panel is existing
Some conventional ripening technologies, and it is not belonging to the feature of the utility model, it does not repeat excessively herein.
As shown in figure 3, toeguard is in collapsed state.At this point, resilient pin 40 passes through the pin hole 33 of 32 lower of core bar
Lock telescopic rod 30.It packs up travel switch 62 and lower body 20 is just set close to one end of upper plate body 10.Therefore, when lower body 20
When rotation to stowed position, packs up travel switch 62 and touch upper plate body 10, elevator control panel is by induction signal.
It is connected between the shank 43 of two resilient pins 40 by interlocking bar 51, interlocking bar 51 is thin bar, has elastic shape
Change ability is buckled with 50 sling of wirerope in interlocking bar 51.When needing to change the state of toeguard, wirerope 50, interlocking bar are pulled
51 drive two bolts to middle slip, the adjustable length of telescopic rod 30, until shank 43 is inserted into another pin hole 33.Shank 43
On spring 42 for preventing its under no external force from deviating from from pin hole 33.
