Abstract
The invention discloses a mechanical electromagnetic safety lock used for an underground lifter. The safety lock is characterized in that the safety lock is provided with a lock belt (1) and a lock body (3), wherein the lock belt (1) is provided with a lock hole (7); the upper end of the lock body (3) is connected with an electromagnet (2); the middle part of the lock body (3) is connected with a bolt (5) through a bolt rotating shaft (4); and the lower end of the lock body (3) is connected with a spring (6). The safety lock has the advantages of simple structure, full automation, safety, reliability and long service life.
Description
Technical field:
The present invention relates to a kind of safety lock, relate in particular to the mechanical abampere full lock of a kind of underground lifting machine special use.
Background technology:
Up to the present, it is mounted that for motor vehicle various lifting machines of domestic maintenance are ground, wherein the safety lock of most of configuration is mechanical automanual system, the action of promptly " locking " is to be driven by extension spring to finish automatically, and " release " needs operating personal to pull the joystick of unblanking with hand, and in the descending process of lifting machine, want a straight pull, relatively effort.There is fraction to dispose mechanical electromagnetism automatic lock, but the operating spring of its automatic " locking " is a torsion spring, and rigidity is less, the power of corresponding electromagnet is also less, " locking " reaches the poor reliability of " release " action, that is the durability of safety control and the use of whole safety lock has been subjected to restriction to a certain degree.And but the stroke range of its self-locking only accounts for the sub-fraction of lifting machine total kilometrage.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art and a kind of compact conformation is provided, can realizes full-automation, safe and reliable, the underground lifting machine of long service life is with mechanical abampere full lock.
Purpose of the present invention can reach by following measure: a kind of underground lifting machine is with mechanical abampere full lock, it is characterized in that it has lock band, lock body, lock is with and is provided with lockhole, the upper end of lock body connects electromagnet, the middle part of lock body connects dead bolt by the dead bolt rotating shaft, and the lower end of lock body connects spring.
In order further to realize purpose of the present invention, described lockhole is rectangular distribution on lock is with.
In order further to realize purpose of the present invention, described lock band is made by the high-strength alloy steel plate.
In order further to realize purpose of the present invention, described spring is a cylindroid helical-coil compression spring.
The present invention can produce following good effect compared with the prior art: the present invention is a full rotation type, it has the cylindroid helical-coil compression spring and the more high-performance electromagnet of enough rigidity and enough installation precompressed amount, and lock is with and is laid with a plurality of lockholes, guarantee that the lifting machine is parked in any position and all can pins, the whole process, the full-automation that have realized lifting process " are locked " and are reached " release ", have that safe reliability is higher, the characteristics of longer service life.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated:
Embodiment: a kind of underground lifting machine is with mechanical abampere full lock (referring to Fig. 1), and it has, and lock is with 1, lock body 3, and lock is with 1 to be made by the high-strength alloy steel plate, evenly is provided with lockhole 7 on it.During use, its upper/lower terminal is individually fixed in the upper and lower of underground lifting machine organism frame.The upper end of lock body 3 connects electromagnet 2, and the middle part of lock body 3 connects dead bolt 5 by dead bolt rotating shaft 4, and the lower end of lock body 3 connects spring 6.Electromagnet 2 provides " release " power, and it has enough power to realize " release " with the elastic force that overcomes spring 6.During use, the lifting post rigid attachment of lock body 3 and lifting machine is so as long as lock body 3 is lived by " lock ", then promptly quilt " lock " is firmly motionless for the lifting post, reaches and guarantees purpose of safety.Dead bolt 5 is done conter clockwise or cw swing around dead bolt rotating shaft 4 under the effect of the moving iron core of electromagnet 2 or spring 6, finish " release " or " locking " action.Spring 6 is a cylindroid helical-coil compression spring, and it has enough installation precompressed amounts guaranteeing when the stand of lifting post (be electromagnet 2 must not), drives dead bolt 5 and enters lock with the lockhole 7 on 1, guarantees the reliability of " locking ".
Rise or descend at the lifting post in the process of (be overhauled vehicle by lifting, landing), electromagnet 2 always electric, the downward ejection dead bolt 5 of its moving iron core is thrown off fully (referring to dotted line position among the figure itself and lockhole 7, this moment, spring 6 was compressed), do not influence the ascending, descending action; When stopped in any position in the ascending, descending process, electromagnet 2 is dead electricity simultaneously, and spring 6 is bounce-back automatically, promoted dead bolt 5 and clockwise rotated, and entered lockhole 7.If when the improper whereabouts of lifting post, when the lower plane of dead bolt 5 contacted with the lower plane of lockhole 7, lock promptly stoped to live the continuation of lifting post descending with 1.Even the lifting post has been parked in the position that dead bolt 5 does not face lockhole 7, after its descending very short distance, dead bolt 5 can enter next lockhole 7, thereby reached safing effect.
