Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an electric saw emergency stop safety structure using the winsler phenomenon includes a circular saw 1, wherein a micro-sensitive current is conducted to an outer ring of the circular saw 1 and electrically connected to a contact 11 after passing through a current amplifier.

The centre of a circle position swivelling joint of annular saw 1 has mobile jib 2, and fixed nut 3 has been cup jointed to the outer lane of mobile jib 2 is fixed, the outer lane fixedly connected with scram piece 4 of mobile jib 2, the outer lane fixedly connected with scram device 5 of scram piece 4, and scram device 5 is provided with six, and evenly distributed is in the outer lane of scram piece 4. The six emergency stop devices 5 work simultaneously, so that the emergency stop failure of the circular saw 1 caused by the failure of a single emergency stop device 5 is avoided, and the stability and the reliability of the structure are improved.

The spring 6 is fixedly connected to the bottom end of the interior of the emergency stop device 5, the liquid cavity 7 is formed in the interior of the emergency stop device 5, the electrorheological body 71 is placed in the liquid cavity 7, and the main components of the electrorheological body 71 are gypsum, lime, carbon powder and olive oil. The electrorheological fluid 71 is in liquid form under different electrical conditions and rapidly changes to a hard solid when energized.

The lower end of the liquid cavity 7 is fixedly connected with a lower sealing baffle plate 8, the upper end of the liquid cavity 7 is fixedly connected with an upper sealing baffle plate 9, and the side ends of the lower sealing baffle plate 8 and the upper sealing baffle plate 9 are tightly attached to the inner wall of the emergency stop device 5. The close fit ensures that the electrorheological fluid 71 does not leak from the interior of the liquid chamber 7.

The upper end of the sealing upper baffle 9 is fixedly connected with a lower stop block 10, the inner end of the emergency stop device 5 is fixedly connected with a contact 11, two contacts 11 of the emergency stop device 5 are arranged, and the contact parts of the contacts 11 are in contact with the current transformer 71.

The outer side of the contact 11 is fixedly connected with a strengthening block 111, the outer side of the emergency stop device 5 is fixedly connected with a fixing screw 12, the inner ring of the circular saw 1 is fixedly connected with a barrier strip 13, the inner ring surface of the barrier strip 13 is fixedly connected with an upper stop block 14, the lower stop block 10 and the upper stop block 14 are meshed with each other, the contact surface of the stop blocks is arranged in a circular arc shape, and meanwhile, the interval between every two upper stop blocks 14 is slightly larger than the width of the lower stop block 10. Circular-arc can guarantee that when scram piece 4 and blend stop 13 rotate relatively, under the cooperation of spring 6, go up dog 14 and lower dog 10 can not hinder circular saw 1's rotation. Meanwhile, the proper width between the upper stop blocks 14 can ensure that the braking distance of the circular saw 1 is not too long, and the spring 6 is effectively stretched.

The fixed surface of circular saw 1 is connected with axis of rotation 15, and axis of rotation 15, fixing nut two 16 and spoke 17 are provided with five, evenly encircle and distribute in mobile jib 2 outer lane. The outer ring of the rotating shaft 15 is fixedly connected with a second fixing nut 16, the side end of the rotating shaft 15 is fixedly connected with a spoke 17, and the side end of the spoke 17 is fixedly connected with a positioning block 18. The positioning block 18 is movably sleeved on the outer ring of the main rod 2, and meanwhile, external power is connected into the positioning block 18. Different from the power input of the conventional circular saw 1, the circular saw 1 is driven to rotate and cut by fixedly connecting the rotating shaft 15, the fixing nut II 16 and the spoke 17 outside, the circular saw 1 and the main rod 2 rotate relatively in the rotating process, and the main rod 2 clamps the circular saw 1 and keeps relatively static during braking.

The working principle is as follows: the circular saw 1 is rotated by an external power input through the rotating shaft 15. When the circular saw 1 normally rotates, the upper stop block 14 rotates relative to the scram block 4, the upper stop block 14 downwards extrudes the lower stop block 10 when the upper stop block 14 contacts the lower stop block 10, the upper stop block 9, the current transformer 71 and the lower stop block 8 are sealed, the spring 6 is compressed, and the upper stop block 14 cannot be clamped by the lower stop block 10 at the moment.

When user's health direct contact circular saw 1, the little sensitive current that circular saw 1 passes through will form the route through human body and ground, pass through current amplifier switch-on contact 11 with the signal of telecommunication simultaneously, make current variant 71 circular telegram, current variant 71 becomes the solid rapidly, simultaneously because contact 11 joint is in the inside of sap cavity 7, and strengthen the fixed of piece 111, current variant 71 keeps relatively fixed with the position of sap cavity 7, when last dog 14 is rotatory and contact dog 10 down, no longer compress spring 6 after dog 10 receives the pressure down, the while keeps the position unchangeable, reach the effect of blocking dog 14, and block rotatory circular saw 1 through blend stop 13, thereby reach emergency braking circular saw 1's effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
