Abstract
The utility model provides a shaft puller. By means of the shaft puller, pin shafts are detached rapidly, time and labor are saved, and maintenance efficiency is greatly improved. The shaft puller comprises a limiting casing pipe and a lead screw. The lead screw is inserted in the limiting casing pipe. A locking nut is installed on the lead screw in a matched mode. A rotating block is fixedly arranged at the top end of the lead screw. A stop spacer used for stopping the locking nut to be located on the outer side of the top end of the limiting casing pipe is fixedly arranged at the top end of the limiting casing pipe. By the adoption of the shaft puller, the pin shafts or other shaft parts with threaded holes can be detached rapidly, the time and the labor are saved, and the maintenance efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of hinge pin disassembling instrument, specifically a kind of Shaft drawer.
Background technology
What ship unloaders hoisted, open and close the employing of cable drum place is SBB365 type slow-speed shaft disk brake (hereinafter to be referred as brake), and this brake uses frequent, very easily causes the brake rim wearing and tearing, when wear extent reaches a half, must change.The brake arm of this model brake adopts axial pin type to connect, brake rim adopts and to be bolted on brake arm, however when changing brake rim due to reasons such as insufficient spaces, the brake rim set bolt can't be dismantled, brake arm integral body can only be pulled down, wait after changing brake rim and recover again.Because pivot pin and the axle sleeve of brake arm is interference fits, add narrow space and the diameter of axle is thicker, so be difficult to dismounting.
In prior art, generally adopt the mode such as hammering copper rod to dismantle, waste time and energy, change a slice brake rim and need 2-3 hour, had a strong impact on maintenance efficiency.
Therefore, urgently design a kind of axle instrument that pulls out of quick release pivot pin.
The utility model content
The utility model provides a kind of Shaft drawer, can the quick-detachment pivot pin, and time saving and energy saving, greatly improve maintenance efficiency.
For reaching above-mentioned technical purpose, the utility model is achieved by the following technical solutions: a kind of Shaft drawer, comprise limit casing and leading screw, described leading screw is plugged in described limit casing, coordinate locking nut is installed on described leading screw, and the leading screw top is installed with rotating block, the top of described limit casing is installed with the stop washer in the outside, described limit casing top by described locking nut backstop.
In the technical solution of the utility model, also comprise following additional technical feature: described rotating block is the hold-down nut that is welded on described leading screw top.
Described rotating block for welding or bolted at the bar shaped handle on described leading screw top.
The internal diameter of described limit casing is 50-80mm, and length is 300-500mm, and described leading screw diameter is 14-20mm, and length is 400-600mm.
Compared with prior art, employing the utility model Shaft drawer can dismantle rapidly pivot pin or other are threaded the axial workpiece in hole, time saving and energy saving, has greatly improved maintenance efficiency.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model most preferred embodiment Shaft drawer.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1, the present embodiment Shaft drawer, comprise limit casing 1 and leading screw 2, leading screw 2 is plugged in limit casing 1, and locking nut 3 is installed on leading screw 2, and locking nut 3 coordinates with threads of lead screw, can turn on leading screw 2, the top of leading screw 2 is installed with rotating block 4 simultaneously, and the top of limit casing 1 is installed with stop washer 5, and the effect of stop washer 5 is the outside, top in limit casing 1 by locking nut 3 backstops.
Concrete, the present embodiment Shaft drawer in use, it is erected to brake pivot pin position, the bottom of limit casing 1 is against on brake, pivot pin inserts the internal cavities of limit casing 1, the screwed hole that leading screw 2 is aimed on pivot pin, in the screwed hole that can drive on leading screw 2 precession pivot pins with spanner or direct hand Screw rotating block 4, precession is to correct position, use handle or directly manual turn locking nut 3, screwing force by locking nut 3 makes leading screw 2 move upward together with pivot pin, and pivot pin is extracted.
Based on technique scheme, optionally, rotating block 4 can be for being welded on the hold-down nut on leading screw 2 tops, as shown in fig. 1, perhaps for the mode by welding or bolted, be fixed on bar shaped handle or other shape handles on leading screw 2 tops, to facilitate turn leading screw 2.When rotating block 4 is hold-down nut, if the screwing force needed is larger, can use as mentioned above wrench operated, if handle-shaped, directly manual operation gets final product.
Wherein, in the present embodiment, to adopt internal diameter be that the seamless steel pipe that 60mm, length are 350mm is made for limit casing 1, and the hollow irony disk that its stop washer 5 is thickness 10mm, external diameter 80mm is welded on the top of limit casing 1; It is 430mm that the model of leading screw 2 is selected M16, length.Certainly, for applicable different pivot pin or other axial workpieces, the internal diameter of limit casing 1 can need to be selected according to actual job in 50-80mm, length in the 300-500mm scope, the diameter of leading screw 2 can be selected in the 400-600mm scope in 14-20mm, length, and the present embodiment is not done concrete restriction to this.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
