In order to achieve the purpose, the utility model adopts the following technical scheme: an arm-clasping type safety device comprises a main beam, electromagnets, a protection arm, an oil pump piston, a transmission rod, guide rails, a movable slider and a rotating shaft, wherein a plurality of electromagnets used for sucking and hanging a sucked piece are hung at the bottom of the main beam, the guide rails are installed on a vertical arm of the main beam, the movable slider is arranged on the inner side of each guide rail in a sliding manner, the oil pump is installed on a cross arm of the main beam, the oil pump piston at the bottom of the oil pump is connected with the movable slider, the movable slider is rotatably connected with one end of the transmission rod, the other end of the transmission rod is rotatably connected with one end of the protection arm, and the protection arm is installed on the main beam through the rotating shaft.

Preferably, the number of the protection arms at the bottom of the main beam is not less than two.

Preferably, each set of arms consists of two.

Preferably, the two protection arms can rotate around the rotating shaft to be closed below the sucked piece.

The utility model has the advantages that:

the utility model discloses an add the protection arm, after oil pump work, the oil pump piston drives the transfer line and drives two protection walls again and open and shut by moving the slider in step, direct pocket protects in the bottom of work piece when making the lifting electromagnet move the work piece, need not to protect by the magnetic device that protects that has a power failure, thereby saved the driving load that this set of device of magnetic is protected because of overweight production in power failure, saved the potential safety hazard that produces because of the internal fault because of this set of device of magnetic is protected in power failure, provide another with pure mechanical system safety insurance.

Wherein: the device comprises a main beam-1, an electromagnet-2, a protection arm-3, an oil pump-4, an oil pump piston-5, a transmission rod-6, a guide rail-7, a movable sliding block-8, a rotating shaft-9 and an absorbed piece-10.

Detailed Description

In order to further explain the technical solution of the present invention, the following detailed description is given by way of specific examples.

As shown in fig. 1-4, the utility model provides an arm-type safety device, which comprises a main beam 1, an electromagnet 2, a protection arm 3, an oil pump 4, an oil pump piston 5, a transmission rod 6, a guide rail 7, a movable slider 8 and a rotating shaft 9;

wherein, girder 1 is the holistic bearing structure of this device, the utility model discloses hang on 1 bottom of well girder and put four and be used for inhaling to hang and hang electro-magnet 2 that is inhaled a 10, install on the perpendicular arm of girder 1 and be used for removing gliding guide rail 7 about slider 8, should remove slider 8 and slide and set up in guide rail 7 inboardly, install oil pump 4 on girder 1's xarm, and oil pump 4 bottom is connected with oil pump piston 5, and be connected on with removal slider 8 through oil pump piston 5, remove slider 8's both ends and rotate through the axostylus axostyle with a transfer line 6 respectively and be connected, two transfer line 6 outside ends rotate through the axostylus axostyle with two protection arms 3 respectively and are connected, two protection arms 3 all install on girder 1 through rotation axis 9.

As shown in fig. 1-3, in this embodiment, two sets of protection arms 3 are provided at the bottom of the main beam 1, and the two sets of protection arms 3 can symmetrically protect two sides of the absorbed element 10, thereby improving the safety.

As shown in fig. 4, each set of protection arms 3 is composed of two pieces, two pieces of protection arms 3 can rotate around the rotation shaft 9 to the lower part of the sucked piece 10 to be closed, and after the two pieces of protection arms 3 are closed, the sucked piece 10 can be stably supported and protected.

The oil pump piston 5 is arranged between the guide rails 7, and the motion range of the oil pump piston 5 is limited by the guide rails 7, so that the oil pump piston 5 drives the movable slide block 8 to move linearly up and down in the guide rails 7.
