Abstract
The invention discloses a self-locked hook which comprises a hook rack, wherein a hook body is hinged on the hook rack; a baffle part is arranged at the opening of the hook body; the middle part of the baffle part is hinged with the hook rack; one end part of the baffle part is a free end; a driving cylinder is arranged between the other end right aligned to the opening of the hook body and the hook rack; a torsion spring is arranged between the hook body and the hook rack; the torsion spring is connected with a sensor for detecting the elastic force of the torsion spring; the sensor is connected with a controller of the driving cylinder; the tensile force of the torsion spring is detected through the sensor and furthermore whether the hook is loaded with a heavy article or not can be detected; if the detection result shows that the hook is loaded with the heavy article, the baffle part can be controlled by the driving cylinder to rotate so as to baffle the opening of the hook body.
Description
Technical field
The present invention relates to a kind of self-locking suspension hook.
Background technology
Lifeboat suspension hook of the prior art, generally include suspension hook frame, middle part is rotated the hook body being connected by the first rotating shaft with described suspension hook frame, rotated the drive block being connected by the second rotating shaft with described suspension hook frame, one end rotates the actuator being arranged on described suspension hook frame, it is fixedly installed on the block piece on described suspension hook frame, the upper end of described hook body has hook portion, opening is formed between described hook portion and described hook body, described block piece is positioned at described opening part, described hook body and described drive block are connected setting, described drive block has the first driving plane, the other end of described actuator has the second driving plane, first drives plane to drive plane to match with second, due to actuator and drive block coordinating by plane and plane between the two, thus both requirement on machining accuracy are higher.
Current hook carries out setting hook and manually carries out with unloading hook and all requiring over, inconvenient operation.
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that a kind of self-locking suspension hook, easy to use.
For achieving the above object, the technical scheme is that and provide a kind of self-locking suspension hook, including suspension hook frame, described suspension hook frame is hinged with hook body, the opening part of described hook body is provided with block piece, the middle part of described block piece and described suspension hook frame are hinged, the one end of described block piece is free end, and just opening to described hook body, it is provided with driving cylinder between its other end and described suspension hook frame, it is provided with torsion spring between described hook body and described suspension hook frame, described torsion spring is connected to the sensor detecting its elastic force, described sensor is connected with the controller of described driving cylinder.
Advantages of the present invention and having the beneficial effects that: detect torsion spring pulling force by sensor, whether detection hook is loaded with weight then, rotates and is stopped by the opening part of hook body by driving cylinder to control block piece after loading.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure: 1, suspension hook frame；2, hook is originally；3, block piece；4, torsion spring；5, sensor；6, cylinder is driven.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of self-locking suspension hook, including suspension hook frame 1, described suspension hook frame 1 is hinged with hook body 2, the opening part of described hook body 2 is provided with block piece 3, the middle part of described block piece 3 and described suspension hook frame 1 are hinged, the one end of described block piece 3 is free end, and just opening to described hook body 2, driving cylinder 6 it is provided with between its other end and described suspension hook frame 1, it is provided with torsion spring 4 between described hook body 2 and described suspension hook frame 1, described torsion spring 4 is connected to the sensor 5 detecting its elastic force, described sensor 5 is connected with the controller of described driving cylinder 6.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
