Abstract
This utility model belongs to seamless steel tube production apparatus technical field, particularly relates to the trundle fast dismounting device of a kind of rearmounted dolly.The utility model discloses the trundle fast dismounting device of rearmounted dolly, including car body and the steel wire rope fixed disk being fixedly installed on vehicle bottom, it is characterized in that, spacing is left in the horizontal direction between trailing wheel and the rear end of steel wire rope fixed disk of car body, two inverted U wheel shaft fixed blocks are welded on car body, hind axle is connected on car body by two inverted U wheel shaft fixed blocks and wheel shaft briquetting, and trailing wheel is arranged at the two ends of hind axle.This utility model dismounting wheel shaft briquetting, changes trailing wheel and hind axle the most easily, without dismounting heavy loaded down with trivial details steel wire rope fixed disk device again, thus is greatly saved maintenance time, reduces the working strength of personnel.
Description
Technical field
This utility model belongs to seamless steel tube production apparatus technical field, particularly relates to the trundle fast dismounting device of a kind of rearmounted dolly.
Background technology
Current perforator background push rod afterbody is all connected with a dolly, and dolly is driven by steel wire rope tension, and there is trundle slideway both sides, and wheel divides forward and backward each one group.Steel wire rope fixed disk is positioned at dolly wheel shaft lower position, and structure comparison is compact.Due to steel wire rope fixed disk bottom dolly relative to place rearward, so the when of the dismounting of Plantago minuta wheel shaft, only need to be unclamped by the tensioner of steel wire rope, i.e. toward sagging, at this moment somewhat sling, can be changed by front truck wheel shaft in dolly front portion by steel wire rope.And trailing wheel is located just at rear steel wire rope fixed disk upper rear, during so changing trailing wheel axletree, it is impossible to easy manipulation as front-wheel, steel wire rope fixed disk device can only be dismantled, dolly of slinging, could take out hind axle.Install as the same.Owing to the production environment of perforating machine is severe, when particularly producing big specification, push rod increases accordingly, and the weight that wheel bears the most greatly increases, and the weight that wheel and bearing are subject to is consequently increased, so being easier to cause wheel damage, or the fracture of axletree.In the case, it is highly detrimental to vehicle wheel maintenance and replacing, the most relatively time consuming effort of each troubleshooting.
Summary of the invention
The purpose of this utility model is to solve techniques discussed above problem, one is provided trailing wheel and hind axle to be changed easily, without dismounting heavy loaded down with trivial details steel wire rope fixed disk device again, thus it is greatly saved maintenance time, reducing the trundle fast dismounting device of the rearmounted dolly of the working strength of personnel, its technical scheme is as follows:
The trundle fast dismounting device of rearmounted dolly, including car body and the steel wire rope fixed disk being fixedly installed on vehicle bottom, it is characterized in that, spacing is left in the horizontal direction between trailing wheel and the rear end of steel wire rope fixed disk of car body, two inverted U wheel shaft fixed blocks are welded on car body, hind axle is connected on car body by two inverted U wheel shaft fixed blocks and wheel shaft briquetting, and trailing wheel is arranged at the two ends of hind axle.
Optimal way is, described car body drain pipe is S-shaped car body drain pipe.
Optimal way is, the level interval between described hind axle and steel wire rope fixed disk is 160mm.
The trundle fast dismounting device of the rearmounted dolly that this utility model provides, concrete structure realization is:
1, two inverted U wheel shaft fixed blocks of processing and fabricating, are leaving the position positioning welding of steel wire rope fixed disk rear end, and its top can set reinforcement gusset and weld with car body so that it is solid and reliable.
2, the car body drain pipe of trailing wheel back upper part makes S type into so that it is do not interfere with hind axle.
3, make two wheel shaft briquettings, fastened after wheel shaft is installed so that it is more stable work.
Simply and cleverly change a social system through this, when changing dolly hind axle every time, only wire rope device need to be unclamped, allow steel wire rope the most naturally hang, is then somewhat sling in dolly rear end；Dismounting wheel shaft briquetting, changes trailing wheel and hind axle the most easily, without dismounting heavy loaded down with trivial details steel wire rope fixed disk device again, thus is greatly saved maintenance time, reduces the working strength of personnel.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the rearmounted dolly of seamless steel tube production perforating machine.
Detailed description of the invention
Below in conjunction with Fig. 1 specific illustrative embodiment:
The rearmounted dolly of seamless steel tube production perforating machine, the rearmounted dolly of described seamless steel tube production perforating machine includes car body 1, one group of front-wheel 2 and one group of trailing wheel 3 it is provided with before and after described car body 1, the bottom of car body 1 is fixedly installed steel wire rope fixed disk 4, it is provided with steel wire rope on steel wire rope fixed disk 4, car body 1 can be carried out tension by steel wire rope and drive；At trailing wheel 3, it is provided with car body drain pipe 5 on car body 1, car body 1 is provided with push rod connector 6 at front-wheel 2.
Optimal way is, spacing is left in the horizontal direction between described trailing wheel 3 and the rear end of steel wire rope fixed disk 4, two inverted U wheel shaft fixed blocks 7 are welded on car body 1, hind axle 8 is connected on car body 1 by two inverted U wheel shaft fixed blocks 7 and wheel shaft briquetting 9, and trailing wheel 3 is arranged at the two ends of hind axle 8.
Optimal way is, described car body drain pipe is S-shaped car body drain pipe.
When in use, the push rod connector of whole car body is connected in the push rod of puncher.And whole car body is to be driven by steel wire rope tension, there is the wheel slideway of car body both sides, and the front wheels and rear wheels of car body can be in the wheel enterprising line slip of slideway.
It is that rear wheel position is moved back by that our company changes trundle shaft device so that it is can avoid steel wire rope fixed disk dexterously when dismounting, thus realize the purpose of convenient replacing dolly wheel shaft.Spacing is left in the horizontal direction between namely described trailing wheel and the rear end of steel wire rope fixed disk.Concrete structure realizes:
1, two inverted U wheel shaft fixed blocks of processing and fabricating, are leaving the position positioning welding of steel wire rope fixed disk rear end, and its top can set reinforcement gusset and weld with car body so that it is solid and reliable.
2, the car body drain pipe of trailing wheel back upper part makes S type into so that it is do not interfere with hind axle.
3, make two wheel shaft briquettings, fastened after wheel shaft is installed so that it is more stable work.
Simply and cleverly change a social system through this, when changing dolly hind axle every time, only wire rope device need to be unclamped, allow steel wire rope the most naturally hang, is then somewhat sling in dolly rear end；Dismounting wheel shaft briquetting, changes trailing wheel and hind axle the most easily, without dismounting heavy loaded down with trivial details steel wire rope fixed disk device again, thus is greatly saved maintenance time, reduces the working strength of personnel.
