Abstract
A kind of disconnected control lifting limiter of cucurbit, it is characterized by comprising limiter shell, limiter pedestal, microswitch and push-pull rods, limiter pedestal is provided in the limiter shell, there are three microswitches, the push-pull rod, and the right side of limiter pedestal is arranged in for setting on the limiter pedestal；The microswitch includes switch A, switch B and switch C, and the microswitch controls total contactor KM1, contactless for hoisting KM2 and decline contactor KM3 respectively.The utility model electric block compared with prior art, has the advantages that 1, this limiter can be used for the cucurbit of different size, improve interchangeability；2, since small dimension line footpath can be used using disconnected control control；3, limiter back panel wiring is simple, can be connected using plugging type plug, improve wiring efficiency；4, after changing control loop, cucurbit is preferably reduced due to the accident for generation of rushing to summit.
Description
Technical field
The utility model relates to arrive electric block field, a kind of disconnected control lifting limiter of cucurbit is especially related to.
Background technique
CD/MD electric block is widely used in the fields such as factory, mine, harbour, warehouse, goods yard at home.As one kind
Common lifting equipment, the LX type circuit fire stop matched are primarily present following shortcoming: 1, internal structure is complicated, rapid wear
Part is more；2, in major loop, the operating current of contact is bigger for movement contact disjunction, and frequent main disjunction contact is easy to damage
It is bad；3, due to being connect in major loop, required line footpath is thicker, but the back panel wiring space of existing cutoff retainer is smaller, wiring ratio
It is more difficult.Due to the vulnerability of the part of circuit fire stop, because limiter damage loses the thing that defencive function causes cucurbit to damage
Part happens occasionally.
Utility model content
The purpose of this utility model will solve above-mentioned technical problem, provide a kind of cucurbit disconnected control lifting limiter.
Purpose of the utility model is realized as follows: a kind of disconnected control lifting limiter of cucurbit, it is characterised in that: including
Limiter shell, limiter pedestal, microswitch and push-pull rod are provided with limiter pedestal in the limiter shell,
There are three microswitches, the push-pull rod, and the right side of limiter pedestal is arranged in for setting on the limiter pedestal；It is described
Microswitch include switch A, switch B and switch C, the microswitch control respectively total contactor KM1, rising contact
Device KM2 and decline contactor KM3.
As a preferred technical scheme: the limiter pedestal is fixed on limiter by symmetrically arranged bolt arrangement
On shell.
As a preferred technical scheme: total contactor and contactless for hoisting cooperation are protected for limes superiors.
As a preferred technical scheme: the decline contactor is protected for limit inferior.
As a preferred technical scheme: the microswitch and total contactor KM1, contactless for hoisting KM2 and decline
It is connected between contactor KM3 by plugging type plug.
The utility model electric block compared with prior art, has the advantages that 1, is equal for the cucurbit of different size
This limiter can be used, improve interchangeability；2, since small dimension line footpath can be used using disconnected control control；3, in limiter
Portion's wiring is simple, can be connected using plugging type plug, improve wiring efficiency；4, it after changing control loop, preferably reduces
Accident of the cucurbit due to generation of rushing to summit.
Detailed description of the invention
Fig. 1 is the utility model structure diagram
Fig. 2 is the utility model wiring diagram
In figure: 1, limiter shell；2, limiter pedestal；3, microswitch；3-1, switch A；3-2, switch B；3-3, it opens
Close C；4, push-pull rod.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, but not as limitations of the present invention: a kind of
The disconnected control lifting limiter of cucurbit, it is characterised in that: including limiter shell 1, limiter pedestal 2, microswitch 3 and push-and-pull
Bar 4 is provided with limiter pedestal 2 in the limiter shell 1, and setting is opened there are three fine motion on the limiter pedestal 2
3 are closed, the right side of limiter pedestal 2 is arranged in the push-pull rod 4；The microswitch 3 includes switch A3-1, switch B3-2
And switch C3-3, the microswitch 3 control total contactor KM1, contactless for hoisting KM2 and decline contactor respectively
KM3。
The limiter pedestal 2 is fixed on limiter shell 1 by symmetrically arranged bolt arrangement.Described always connects
Tentaculum KM1 and contactless for hoisting KM2 cooperation is protected for limes superiors.The decline contactor KM3 is protected for limit inferior.Institute
Connected between the microswitch 3 and total contactor KM1, contactless for hoisting KM2 and decline contactor KM3 stated by plugging type plug
It connects.
When specific implementation: limiter shell uses the shell of routine 20A cutoff retainer.Three microswitches have been serially connected in respectively
It rises in contactor and decline contactor circuit, wherein two microswitches (switch A and switch B) are protected for limes superiors, remaining
One (switch C) is protected for limit inferior.The action form of limiter be still it is plug-type, there is 3 tunnel control loop of disjunction and double
To the function of limit.
While breaking control formula limiter as defencive function using LXS type, original control loop is improved, in disconnected control limit
On the basis of position device limits defencive function up and down, the function of preventing contactless for hoisting contact adhesion from rushing to summit accident is increased.
Specific control program can be with reference to Fig. 2 when suspension hook is run to upper limit position, two microswitches on limiter
(switch A and switch B) simultaneously operation, is each turned off the control loop of contactless for hoisting KM2 and total contactor KM1, at this time suspension hook
It can not run up.Operator is needed to press starting control button, after the suction of total contactor, suspension hook can be run down.
When suspension hook is run to lower limit position, decline microswitch (switch C) movement, cutting decline contactor KM3 times
Road, suspension hook can not be run down, but can be run up.
In addition if contactless for hoisting KM2 sticks together when operation to upper limit position, total contactor KM1 be will be switched off, and hang
Hook stops rising, and presses rising button again at this time, and suspension hook will not continue to rise, to prevent cucurbit from rushing to summit accident.
The above embodiments of the present invention is only the citing for clearly demonstrating the utility model and being done, but is not used to
The protection scope of the utility model is limited, all equivalent technical solutions also belong to the scope of the utility model, the utility model
Scope of patent protection should be limited by every claim.
