Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5 and Fig. 6, this device is made up of guide rail cat ladder and the self-locking device laying respectively at the guide rail cat ladder left and right sides, the self-locking device be positioned on the left of guide rail cat ladder comprises brake body 1, handrail 2 and auxiliary braking block 3, brake body 1 has groove 8 left from right side wall, the left-right parts of groove 8 is narrower and be square, mid portion is wider and be trapezoidal, brake body 1 has backward the through hole 10 running through rear wall from front side wall, and through hole 10 is through the left half of groove 8, axle II 6 is interspersed with in through hole 10, the left end of brake body 1 has fixing hole 7, the lower end of handrail 2 is fixed on the top of brake body 1, the top of auxiliary braking block 3 from front side wall backward sidewall be interspersed with axle I 4, the rear and front end of axle I 4 is fixed with roller 5 respectively, the bottom of auxiliary braking block 3 and stage clip 9 are located in the left half of groove 8, the middle part of axle II 6 is successively through the bottom of auxiliary braking block 3 and the main body of stage clip 9, the top, upper end of stage clip 9 is pressed on the left side wall of auxiliary braking block 3, the top, lower end of stage clip 9 is pressed on brake body 1, be positioned at the self-locking device on the right side of guide rail cat ladder identical and symmetrical with the self-locking device structure in left side, guide rail cat ladder comprises left rail 11, right guide rail 12 and multiple cross bar 13, each cross bar 13 is evenly distributed from top to bottom, their two ends, left and right are separately fixed on left rail 11 and right guide rail 12, the cross section of left rail 11 and right guide rail 12 is T-shape, the left side wall of left rail 11 and the right side wall of right guide rail 12 all front and back are outstanding, and be each passed through groove 8 mid portion of each self-corresponding self-locking device, each self-locking device can be moved up and down along left rail 11 and right guide rail 12 respectively.
On operating personnel during shaft tower, fixing hole 7 on brake body 1 is connected with safety door hook, safety door hook is connected with one end of safety rope, the other end of safety rope is connected with human body safety belt, both hands hold the handrail 2 of self-locking device, also hold left rail 11 and right guide rail 12 in the lump simultaneously, the handrail of hand to self-locking device applies a pressure, now handrail 2 and each guide rail parallel, roller 5 is subject to the active force of guide rail, drives auxiliary braking block, makes stage clip 9 pressurized, self-locking device along with operating personnel right-hand man alternately mobile, roller 5 rolls along with the movement of self-locking device on guide rail.In moving process, the palm of self-locking device handrail not separating operation personnel all the time, operating personnel operating personnel is once fall, auxiliary braking block 3 rebounds rapidly under the elastic force effect of stage clip 9, handrail getaway face, and the groove 8 on brake body 1 is no longer parallel with guide pass, such self-locking device locking rapidly under the acting in conjunction of spring force and human bady gravitational, brake body 1 is stuck on left rail 11 and right guide rail 12, stops human body fall, ensures personal safety.
