Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
Referring to fig. 1, an embodiment of the present invention includes:
the over-speed protection device for the stacker carrier is installed on a stacker carrier 14, the stacker carrier 14 can move up and down along a guide rail preset on a stacker upright post 15 under the traction of a traction rope 4, a safety gear 1 of the stacker carrier protection device and a safety gear triggering mechanism form the safety gear triggering mechanism, the safety gear triggering mechanism comprises a pulley traction part and a lever triggering part, and the pulley traction part is movably connected with the lever triggering part; the pulley traction part comprises a traction pulley 13, a pulley mounting plate 2, a pulley fixing plate 12, a bolt 3 and a push rod 11, wherein the pulley mounting plate 2 is fixed on an objective table 14 through the bolt 3, the pulley fixing plate 2 is mounted on the traction pulley 13, a traction rope 4 of the objective table 14 penetrates through the traction pulley 13, the pulley fixing plate 12 is connected with the push rod 11 through a plurality of bolts 3 with the same specification, the pulley mounting plate 2 is provided with corresponding smooth through holes for a screw rod of the bolt 3 to pass through, and a high-strength spring structure is arranged on the screw rod between the push rod 11 and the pulley mounting plate 2; the lever trigger part comprises a trigger lever and a safety rope 5, the safety rope 5 is connected with an objective table speed governor, the trigger lever comprises a lever middle shaft 7, a lever long arm 8 and a lever short arm 9, the lever middle shaft 7 is movably connected with a push rod 11 through the lever long arm 8, the lever short arm 9 is connected with the safety rope 5 and the lever middle shaft 7, and the lever middle shaft 7 is fixed on an objective table 14; the pair of safety tongs 1 is fixed on two sides of an object stage 14 and can act simultaneously after being triggered to prevent the object stage 14 from being stressed unevenly and damage the structure, the clamping part of the safety tongs 1 is attached to a preset guide rail on an upright post 15, the switching position of the safety tongs 1 is arranged on a path of a long lever arm 8 rotating around a lever middle shaft 7, and when a push rod 11 pushes forwards or a safety rope 5 pulls the short lever arm 9, a rod body of the long lever arm 8 can trigger the switching of the safety tongs 4.
The pulley mounting plate 2 is provided with a U-shaped groove, the wheel shaft of the pulley extends into the U-shaped groove, the U-shaped groove can standardize the moving track of the traction pulley 13, and the traction pulley 13 is prevented from shaking left and right.
When the pulley shaft reaches the bottom of the U-shaped groove, a gap is reserved between the bottom of the pulley fixing plate 12 and the bottom of the pulley mounting plate 2, and the pulley fixing plate 12 is prevented from being reset on the bolt 3 by a compression spring structure when the traction rope 4 is broken to cause direct impact between the quick falling process and the pulley mounting plate 2.
The diameter of the smooth through hole is 1.1 ~ 1.3.3 times of the diameter of the screw, the reason that the diameter of the smooth through hole is larger than the diameter of the screw is that the push rod 11 at the top of the bolt 3 does arc motion in the process of pushing the long arm of the lever, if the through hole is matched with the screw too tightly, the push rod 11 is easy to be blocked, and the purpose of triggering the safety gear 1 cannot be achieved.
Still install 2 between push rod 11 and the pulley mounting panel 2 and pull reset spring 10, pull reset spring 10 symmetry and install in the outside of bolt 3, the total intensity that pulls reset spring 10 does not exceed 1/5 of the spring total intensity of spring compression structure on the screw rod. The function of the traction return spring 10 is to bring the push rod 11 back to the initial state after the problem of excessive speed of the carrier 14 is solved, so that the total strength of the traction spring cannot be too high or too low.
The safety rope tensioning sleeve 6 is arranged at the position where the short lever arm 9 is connected with the safety rope 5, and the tension of the safety rope 5 can be adjusted to a design state by rotating the safety rope tensioning sleeve 6 in the installation process of equipment.
The length ratio of the short lever arm 9 to the long lever arm 8 is 1:4 ~ 10, so that the pulling stroke of the safety rope 5 can be effectively amplified, and the reaction sensitivity of the protection device is improved.
The operation principle of the invention is as follows:
in the process that the traction rope 4 pulls the bolt 3 through the traction pulley 13 to drive the stacker objective table 14 to move, traction force acts on the pulley mounting plate 2 fixed on the objective table 14 through the bolt 3, a spring on the bolt 3 is stressed and compressed, meanwhile, a fixed push rod 11 at the top end of the bolt 3 is connected with the lever long arm 8, and the lever short arm 9 is connected with the speed-limiting safety rope 5 tensioned in advance. When the objective table 14 normally operates, the elastic force of the spring is balanced with the traction force of the traction rope 4 and the tension force of the safety rope 5, when the traction rope 74 is accidentally broken, the traction force on the traction rope 4 disappears, the spring on the bolt 3 resets to drive the bolt to integrally push the push rod 11 downwards, the push rod 11 pushes the lever long arm 8 to trigger the safety gear 1, when only overspeed occurs, the speed limiter clamps the safety rope 5, the tension force of the safety rope 5 is increased, the lever short arm 9 is pulled to drive the lever long arm 8 to rotate, and the switch of the safety gear 1 is triggered.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
