Abstract
The utility model relates to the technical field of crane safety assurance, in particular to a crane safety protecting door lock, which is characterized in that a crane door is provided with a door lock, the door lock consists of a lock body, a locking mechanism arranged in the lock body and a proximity switch, and the proximity switch is connected with a crane limit control loop. The utility model has the advantages of simple structure, easy manufacturing, low cost, convenient popularization, reliable protection and very low failure rate, and significantly avoids injury on personnel caused bymisoperation.
Description
Technical field
The utility model relates to crane safety control technical field, particularly a kind of crane safety guard-safeguard door lock.
Background technology
Crane is a visual plant during enterprise produces, because its aloft work is classified as enterprise's special safety emphasis equipment by country, safety is particularly important.The door of walking on stage in crane entrance door, intermediate door and both sides is provided with gate pole limit switch, but this switch is a LX10 series travel switch owing to what adopt, and its internal actions part material is plastics, in use is prone to aging, brittle failure, and fault rate is higher.Simultaneously, the precision of this switch is lower, misoperation often occurs, because vibrations will cause full car power down, causes operating personal to search the trouble point difficulty, the trouble removal difficulty in operational process.And as special equipment, its entrance door does not have door lock, and uncontrollable personnel come in and go out, and very easily cause human casualty accident.
Summary of the invention
The purpose of this utility model provides and a kind ofly collects door lock and the maximum safe limit function is the crane safety guard-safeguard door lock of one.
The purpose of this utility model realizes by following technical proposals.
A kind of crane safety guard-safeguard door lock of the present utility model is characterized in that establishing a door lock on the crane door, this door lock is by lock body, is located at the catch gear in this lock body and forms near switch, and this is connected with described crane limit control loop near switch.
Principle of work of the present utility model is as follows:
The backset top of door lock is identical with common lock, and it act as locking crane door, guarantees that the crane door can not be opened in the crane operational process.The bottom of backset is to transmit signal near switch, when door is opened, is in off-state near switch, and the overhead crane control ring current does not have electricity at this moment, can't the open operation crane; When door resets when closing, be in on-state near switch, this moment the overhead crane control ring current get electric, can the start-up operation crane.
The utility model has the advantages that: simple in structure, be easy to manufacture; Cost is low, is convenient to promote; Protection is reliable, and fault rate is extremely low; The injury accident of greatly having avoided maloperation that personnel are caused.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, a kind of crane safety guard-safeguard door lock of the present utility model, it is characterized in that establishing on the crane door door lock, this door lock is by backset 1, lock body 2, be located at the catch gear 3 in this lock body 2 and form near switch 4, this is connected with described crane limit control loop 5 near switch 4, adopts this crane safety guard-safeguard door lock, the injury accident of greatly having avoided maloperation that personnel are caused, and simple in structure, be easy to manufacture; Cost is low, is convenient to promote effectively.
