Abstract
The utility model discloses a kind of overhead manned equipment drive wheel or tail wheel off-axis fender guard; suspension bracket is equipped with drive wheel or tail-pulley device; the drive wheel or tail wheel of drive wheel or tail-pulley device are equipped with bearing support; at bearing support, outer backing ring is housed; at suspension bracket, suspension hook adapter plate is housed; at suspension hook adapter plate, suspension hook is housed, the below of the coupler body of suspension hook backing ring outside.The utility model has following technique effect, one is that this apparatus design is reasonable, by the socket of hook with bearing support, when there is fracture in axle drive shaft or tail-gear spindle, hook can effectively carry axle drive shaft or tail-gear spindle, prevent drive wheel or tail wheel from falling, suspension hook being equipped with limiting stopper can prevent drive wheel or tail wheel from too swinging and causing the generation of steel rope lifting rope situation by actv., ensures the personal security taking overhead manned equipment; Two is that this apparatus structure is simple, cost is low, and Assembly &Disassembly is convenient.
Description
Technical field
The utility model relates to a kind of overhead manned equipment drive wheel or tail wheel fender guard.
Background technology
Overhead manned equipment is that a kind of conventional mining conveying takes advantage of people's equipment, its frame head and tail is generally installed on excavation support, formation overhead type is installed, the drive wheel of overhead manned equipment is driven by axle drive shaft, tail wheel relies on tail-gear spindle to drive, draw steel rope operation, axle drive shaft longitudinal load-bearing the weight of drive wheel simultaneously, tail-gear spindle longitudinal load-bearing the weight of tail wheel, lateral bearing the convolution pulling force of steel rope operation and the pulling force of heavy-hammer-tightening simultaneously, when axle drive shaft or tail-gear spindle aging or stressed too quickly time can rupture, drive wheel or tail wheel is caused to fall, cause safety misadventure.
Current axle drive shaft or tail-gear spindle mainly adopt the method for hollow shaft inner sleeve solid axle to realize off-axis protection, first have hollow shaft work, again by solid axle Inhaul operation after hollow shaft ruptures.There is following defect in the method: one, and because the overall diameter of axle is limited, hollow shaft axial wall is thinner, and the solid axle diameter of axle is less, and bearing capacity reduces, and causes axle axle drive shaft more easily to rupture; Its two, after hollow shaft fracture, solid axle substitutes and works on, and equipment can not be out of service, and be not easy to find the fracture of hollow shaft, when solid axle ruptures again, then equipment is not protected; Its three, require higher to the processing of axle and setting accuracy, be not easy Assembly &Disassembly, be not easy after axle fracture to change.
Utility model content
The purpose of this utility model is to provide a kind of overhead manned equipment drive wheel or tail wheel off-axis fender guard.
The technical solution of the utility model is; a kind of overhead manned equipment drive wheel or tail wheel off-axis fender guard; suspension bracket is equipped with drive wheel or tail-pulley device; the drive wheel or tail wheel of drive wheel or tail-pulley device are equipped with bearing support; at bearing support, outer backing ring is housed; at suspension bracket, suspension hook adapter plate is housed, at suspension hook adapter plate, suspension hook is housed, the below of the coupler body of suspension hook backing ring outside.
On bearing support, interior backing ring is equipped with in the inner side of outer backing ring, and outer backing ring and interior backing ring 11 have gap, and suspension hook is outside in backing ring and Neto ring gap, the below of coupler body backing ring and interior backing ring outside.
On suspension hook, limiting stopper is equipped with in the top of outer backing ring and interior backing ring.
The utility model has following technique effect, one is that this apparatus design is reasonable, by the socket of hook with bearing support, when there is fracture in axle drive shaft or tail-gear spindle, hook can effectively carry axle drive shaft or tail-gear spindle, prevent drive wheel or tail wheel from falling, suspension hook being equipped with limiting stopper can prevent drive wheel or tail wheel from too swinging and causing the generation of steel rope lifting rope situation by actv., ensures the personal security taking overhead manned equipment; Two is that this apparatus structure is simple, cost is low, and Assembly &Disassembly is convenient.
Accompanying drawing explanation
Front view when Fig. 1 is the utility model normal condition.
Fig. 2 is A-A face birds-eye view in Fig. 1.
Fig. 3 is the front view that the utility model works as when fracture occurs for axle drive shaft or tail-gear spindle.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of overhead manned equipment drive wheel or tail wheel off-axis fender guard, suspension bracket 1 is equipped with drive wheel or tail-pulley device, the drive wheel or tail wheel 2 of drive wheel or tail-pulley device are equipped with bearing support 5, at bearing support 5, outer backing ring 6 is housed, at suspension bracket 1, suspension hook adapter plate 7 is housed, at suspension hook adapter plate 7, suspension hook 8 is housed, the quantity of suspension hook 8 is not limit, the below of the coupler body 10 of suspension hook 8 backing ring 6 outside; On bearing support 5, interior backing ring 11 is equipped with in the inner side of outer backing ring 6, and outer backing ring 6 and interior backing ring 11 have gap, suspension hook 8 outside backing ring 6 with interior backing ring 11 gap, the below of coupler body 10 backing ring 6 and interior backing ring 11 outside; On suspension hook 8, limiting stopper 9 is equipped with in the top of outer backing ring 6 and interior backing ring 11.When fracture occurs for axle drive shaft or tail-gear spindle 3, the coupler body 10 of suspension hook 8 hooks outer backing ring 6 and interior backing ring 11, and limiting stopper 9 can prevent drive wheel or tail wheel from too swinging and causing the generation of steel rope lifting rope situation by actv..
