Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Be illustrated in figure 1 a specific embodiment of the present utility model, this is applicable to the modulated brake power formula gradual anti-falling safety device that the main limb of support body makes guide rail, comprise pedestal 1, described pedestal 1 be provided with voussoir 2, adjustment part 3 of rushing to summit, slide block 4, disc spring 9, reset tension spring 11 and brake cable 13.
Described pedestal 1 to be wrapped tightly on the main limb of support body 15 by the guide wheel assembly 12 of its corner and can move up and down along the main limb 15 of support body;
The lateral surface of described voussoir 2 is inclined-plane, medial surface is set to the vertical cambered surface that limb 15 cylindrical main with support body matches, described voussoir 2 is two pieces, is arranged at the both sides of the main limb 15 of support body respectively, described voussoir 2 top connects brake cable 13, bottom connects reset tension spring 11, the other end of described reset tension spring 11 is fixed on bottom pedestal 1, and the other end of described brake cable 13 is connected with the lever system linked with velocity limiter;
Next-door neighbour's voussoir 2 lateral surface is provided with slide block 4, described slide block 4 has the medial surface with described voussoir 2 inclined-plane same slope, lateral surface is a vertical plane surface, can laterally slide in the upper and lower horizontal slot that described slide block 4 is arranged at pedestal 1, described pedestal 1 is fixedly installed bent plate 10, in normal state, bottom described voussoir 2 with bent plate 10 conduct oneself with dignity and reset tension spring 11 effect under contact, with the main limb of support body 15 to keep suitable braking gap;
The lateral surface of described voussoir 2 is close to the medial surface of slide block 4 and has guide plate 5 to be connected therebetween, and described guide plate 5 is a bent plate, and a side is fixed on slide block 4, in the chute of another side inserted wedge 2, make voussoir 2 be close to the inclined-plane up-and-down movement of slide block 4;
Disc spring 9 and disc spring tab 8 is connected with by disc spring bolt 6 between the lateral surface of described slide block 4 and pedestal 1, adjust the initial pressure of disc spring 9 and the level attitude of slide block 4 by the sheet number and thickness that adjust disc spring bolt 6 and increase and decrease disc spring tab 8, lock with lock-bit pad 7;
The top of described voussoir 2 is provided with adjustment part 3 of rushing to summit, the braking force of the main limb 15 of adjustment voussoir 2 pairs of support bodys.
As preferred mode, specifically, be connected with the screw on slide block 4 through pedestal 1, disc spring tab 8, disc spring 9 after the sheathed lock-bit pad 7 of described disc spring bolt 6 root.
As preferred mode, specifically, described in adjustment part 3 of rushing to summit be set to bolt, be threaded connection with voussoir 2, and on bolt, arrange female 14 location of the back of the body, described brake cable 13 is connected with voussoir 2 by adjustment part 3 of rushing to summit.Adjustment part 3 of rushing to summit is adjustment voussoir 2 miles of relative movement, when bolt of rushing to summit lean out voussoir more than 2 time, voussoir 2 miles of relative movement is just short, voussoir 2 closes up just few, and voussoir 2 horizontal displacement that voussoir 2 produces after being close to the main limb 15 of support body is just few, just few to disc spring 9 amount of compression, therefore the antagonistic force of disc spring 9 pairs of voussoirs 2 is just little, so voussoir 2 pairs of support body main limb 15 braking forces are just little, and friction is just little, and the stopping distance of cage is just long.Otherwise, when bolt of rushing to summit lean out voussoir 2 few time, voussoir 2 miles of relative movement is just long, voussoir 2 closes up just many, and voussoir 2 horizontal displacement that voussoir 2 produces after being close to the main limb 15 of support body is just large, just large to disc spring 9 amount of compression, therefore the antagonistic force of disc spring 9 pairs of voussoirs 2 is just large, so voussoir 2 pairs of support body main limb 15 braking forces are just large, and friction is just large, and the stopping distance of cage is just short.
As preferred mode, the medial surface of described voussoir 2 adopts asbestos alloy material, increases friction force and durability, simultaneously very little to the injury of support body main limb.
Guide wheel assembly 12 contacts with main the wrapping tightly of limb 15 of support body, the line of centers of the main limb 15 of support body is overlapped as far as possible with the line of centers between two voussoirs 2, make the distance between the intrados of two voussoirs 2 and the extrados of the main limb of support body 15 consistent as far as possible, and make the positive pressure of two voussoirs, 2 pairs of main limbs of support body 15, friction, braking force consistent as far as possible when braking.
The utility model in use, during normal working, under the pulling force of reset tension spring 11, pull voussoir 2 to abut against on bent plate 10, make voussoir 2 and the main limb 15 of support body keep the gap of 2 ~ 3mm, during cage limb 15 up-and-down movement main along support body, not main with the support body limb 15 of voussoir 2 contacts.
When cage hypervelocity is fallen, trigger velocity limiter action, stop passes fast steel rope, and drive brake cable 13 by lever system, voussoir 2 is pulled to do closing in campaign along guide plate 5, when the main limb 15 of voussoir 2 and support body contacts, the main limb 15 of support body also gives voussoir 2 antagonistic force simultaneously, voussoir 2 is made to extrude slide block 4, slide block 4 is extruding disk spring 9 just, makes the main limb 15 of two voussoirs, 2 pairs of support bodys produce positive pressure, friction, braking force under the antagonistic force of disk spring 9, and cage just slows down, last stop on the main limb 15 of support body, thus prevents falling of cage.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
