Detailed description of the invention
As shown in Figures 1 to 8, a kind of construction hoist falling-proof insurance system of the present invention, including guide rail bracket 1 and cage 6, Guide rail bracket 1 is positioned on underframe guardrail 9, described guide rail bracket 1 just to two sides outside be respectively equipped with tooth bar 7, described cage 6 is provided with one Group pulley, pulley moves along guide rail bracket 1, and described cage 6 is provided with motor 8, and motor 8 is connected with gear shaft 10, gear shaft 10 Engaging with tooth bar 7, the upper and lower surface at cage 6 is respectively equipped with at least Liang Zu safety plug mechanism 2, Liang Zu safety plug mechanism 2 can be arranged side by side, it is also possible to be arranged under the overlay, and only provide one group in Fig. 1 and Fig. 2, and additionally one group is not drawn into, described guarantor Danger pin mechanism 2 comprises base 26, electric magnet 21 and safety plug mechanism pin core 24, and described safety plug mechanism pin core 24 is positioned at housing In, housing is arranged on cage 6 by base 26, and safety plug mechanism pin core 24 is cylindrical shape, and safety plug mechanism pin core 24 exists The one end being positioned at housing is provided with circular groove, is provided with block 23 on housing, and block 23 one end is positioned at groove, logical Crossing block 23 and limit the stroke of safety plug mechanism pin core 24, be provided with spring 27 in housing 24, spring 27 is at safety plug block 23 not Having pretightning force when stretching out, its two ends are followed closely respectively and are sold on core rear end 251 at safety plug mechanism shell bonnet 241 and safety plug mechanism, Spring 27 one end is sold core 24 with safety plug mechanism and is connected, and electric magnet 21 is positioned on housing, and electric magnet 21 has been inserted into electric magnet and has moved Iron core 22, described electric magnet 21 is connected with controller 4, and controller 4 is connected with the 3-axis acceleration sensor 5 being positioned on cage 6, When electric magnet 21 is not powered on, electric magnet moves iron core 22 for the state of stretching out, and is inserted in groove, and electric magnet moves iron core 22 and blocks guarantor Danger pin mechanism pin core 24 makes spring 27 be compressed to beeline, and controller 4 controls electric magnet 21 when being energized, and electric magnet moves iron core 22 pumpbacks, safety plug mechanism pin core 24 ejects under spring 27 acts on, and by block 23, safety plug mechanism pin core 24 is stopped Motion, safety plug mechanism pin core 24 is inserted in guide rail bracket 1, cage 6 stop motion.
In the present invention, described guide rail bracket 1 comprises four vertical guide rails, and adjacent guide rail is uniformly distributed by several Connecting tube 11 connect.The lower surface of described cage 6 and upper surface are respectively equipped with Liang Zu safety plug mechanism 2, and respectively first protects Danger pin mechanism, the second safety plug mechanism, the 3rd safety plug mechanism and the 4th safety plug mechanism, the first safety plug mechanism, the second guarantor Danger pin mechanism, the 3rd safety plug mechanism and the 4th safety plug mechanism are respectively equipped with the first safety plug mechanism pin core, the second safety plug Mechanism's pin core, the 3rd safety plug mechanism pin core and the 4th safety plug mechanism pin core, the first safety plug mechanism pin core, the second safety plug Mechanism's pin core, the 3rd safety plug mechanism pin core and the shear strength of the 4th safety plug mechanism pin core.Described first safety plug mechanism The shear strength of pin core and the second safety plug mechanism pin core less than the shear strength of connecting tube, the 3rd safety plug mechanism pin core and the The shear strength of four safety plug mechanism pin cores is not less than the shear strength of connecting tube.Described first safety plug mechanism pin core, second Safety plug mechanism pin core, the 3rd safety plug mechanism pin core and the 4th safety plug mechanism pin four materials of core be respectively aluminum, duralumin, Ordinary steel, high strength steel, connecting tube 11 is steel pipe.
In the present invention, electric magnet moves iron core 22 when being not powered on for the state of stretching out, and it is outside to block safety plug block 23 Stretch out.Spring 27 has pretightning force when safety plug block 23 does not extends out, and its two ends are followed closely respectively at safety plug mechanism shell bonnet 241 Sell on core rear end 251 with safety plug mechanism.When electric magnet 21 is energized, electric magnet moves iron core 22 pumpback, safety plug mechanism pin core 25 outwards eject under the effect of spring 27 pretightning force, simultaneously because the effect of safety plug block 23, block safety plug mechanism pin Core 25, prevents safety plug mechanism pin core 25 from coming off.
Seeing Fig. 7 and Fig. 8, microcontroller 4, alarm lamp 3,3-axis acceleration sensor 5 and safety plug mechanism 2 form intelligence Energy control system, the control flow of intelligence control system is as follows: user turns on the power switch, intelligence control system entrance work shape State, microcontroller 4 obtains the real time acceleration signal of cage 6 at 3-axis acceleration sensor 5, and filtered and integration is asked Obtain the instantaneous velocity of cage 6, afterwards the instantaneous velocity of cage 6 is compared with cage 6 maximal rate preset, it is judged that cage The speed of 6 is the most normal, if normal, control system continues to gather 3-axis acceleration sensor 5 signal, if abnormal, micro- Type controller 4 controls alarm lamp 3 and reports to the police, and makes the electric magnet 21 of safety plug mechanism 2 be energized.
Seeing Fig. 2, when the speed that microcontroller 4 judges cage 6 is normal, electric magnet 21 is not powered on, safety plug mechanism Pin core 25 is entirely located in safety plug mechanism shell 24, and cage 6 is under the effect of motor 9, by gear 10 and the engagement of tooth bar 7 Power, cage 6 moves up and down in vertical direction along guide rail bracket 1.
Seeing Fig. 1, when microcontroller 4 judges the velocity anomaly of cage 6, controller controls the first electricity below cage Magnet is energized, and the first electric magnet moves iron core pumpback, first safety plug mechanism pin core outside bullet under the effect of spring 27 pretightning force Going out, the first safety plug mechanism pin core will collide with a nearest connecting tube, due to cutting of the first safety plug mechanism pin core Shearing stress is cut off less than the shear strength of connecting tube, the first safety plug mechanism pin core, and the speed of cage reduces, then controller Controlling the second safety plug mechanism pin core to stretch out, cut off equally, speed reduces further, and controller then controls the 3rd safety plug Mechanism's pin core and the 4th safety plug mechanism pin core stretch out, and owing to speed reduces, and shear strength is strong more than the shearing of connecting tube Degree, thus safety plug mechanism 2 stops moving downward, and then make the cage 6 affixed with safety plug mechanism 2 stop falling, anti-falling stop The accident that falls occurs.
The above is only the preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should It is considered as protection scope of the present invention.
