Abstract

The utility model relates to a novel anti-slide pulling apparatus, comprising a screw rod, a support arm, a draw hook, etc. The appearance of the pulling apparatus is basically uniform with the common non-anti-slide pulling apparatus. A draw rod is fixed on the support arm through screw bolts, the center of the support arm is matched with the screw rod, and then the utility model is used. As the size of the anti-slide angle of the draw rod is specified as 1 DEG to 10 DEG, the utility model has the anti-slide function, when the anti-slide device and the accessory are not provided. The utility model achieves the anti-slide purpose when the anti-slide device and the accessory are not provided.

Description

Anti-slide pulling apparatus

The utility model relates to a kind of extracting tool of plant equipment, and particularly a kind of being applicable to drawn the pulling off device that unloads the various parts that are loaded on the axle head position.

Existing common puller has three-jaw, two pawls, oil pressure three kinds, and these pullers are generally not anti-skidding, so result of use is poor; And the complex structure of the puller of band shoe, remove the parts that generally all have, outside drag hook, support arm, screw rod, thread bush, also is furnished with antiskid plate, antiskid plate be must adjust during operation and drag hook and the part fastening that needs dismounting made, can operate by the method for common use puller, so the operation sequence more complicated is inconvenient again.

Task of the present utility model will provide a kind of shoe that do not have, but puller that can be anti-skidding.

Task of the present utility model is finished like this: because the power of the zoom-out function of puller, mainly be the size of angle that depends on the towing pad center of circle vertical line of the bill of drag hook and drag hook pommel, this angle can be described as the angle of traction, promptly anti-skidding angle.Suitably the anti-skidding angle of size can determine the tightening force of only drag hook to part.This phenomenon past often is not much accounted of when the anti-skidding puller of design.The utility model then utilizes this phenomenon, design appearance substantially to the common not anti-skidding similar new-type antiskid puller of puller, this puller also is made of screw rod, support arm, drag hook and bolt.But, the center of circle vertical line of the towing pad on the pommel of its drag hook (being bolt hole) and must be in 1 °-10 ° scope from the angle of the connecting line of this center of circle and drag hook bill, this angle can be described as anti-skidding angle (or being called the angle of traction), proof after putting into practice, best anti-skidding angle is 5 °.

The anti-skidding puller of designing thus can be under the condition of omitting shoe and annex, constitutes so far with the parts similar to common not anti-skidding puller and can think the simplest anti-skidding puller, can reach reliable skidproof effect fully.In use, by general commonsense method operation, the drag hook of new-type antiskid puller gets final product automatic fastening part to be removed, particularly when dismounting trough belt wheel, can directly hang in the belt grooves and pull out.Owing to needn't adjust shoe, then its operation just seems very convenient, and is simple.

The puller of the utility model indication can manufacture three-jaw, two pawls, oil pressure type.Its drag hook also can be crooked shape, general angle of bend from 97 °-127 ° all right, can dismantle the bigger part of diameter like this.

To make detailed elaboration to this real new-type antiskid puller with reference to the accompanying drawings below.

Fig. 1 is the structural representation of this new-type antiskid puller;

Fig. 2 is the drag hook design diagram of this new-type antiskid puller;

Fig. 3 is the puller schematic diagram with shoe on the market.

With reference to the accompanying drawings, a kind of new-type antiskid puller is made of screw rod (1), support arm (2), drag hook (4), bolt (3), the towing pad (6) of its drag hook (4) is the angle between the vertical line in the center of circle of the connecting line (8) of the center of circle of bolt hole and drag hook bill (9) and towing pad (6), is called the anti-skidding angle or the angle of traction.The angle at this anti-skidding angle should be set in 1 °-10 ° the scope, and best anti-skidding angle should be 5 °.Plant drag hook and support arm, screw rod thus, and pull bar is fixed on the support arm, just constituted the new-type antiskid puller with bolt.In use, the using method that needs only with common puller can reach anti-skidding effect of pulling out part.

Claims

1, a kind of new-type antiskid puller, constitute by support arm, screw rod, drag hook, the connecting line that it is characterized in that the center of circle of the bill of its drag hook and drag hook pommel, and by the angle (anti-skidding angle) between the vertical line in this center of circle, should be set within 1 ° of-10 ° of scope.

2,, it is characterized in that anti-skidding angle the best of its pull bar is 5 ° according to the anti-skidding puller of claim 1.
