Description

Rotary pin pulling tool

Technical Field

The utility model belongs to the pin pulling instrument field that generating set used especially relates to a formula of revolving pin pulling instrument that generating set used.

Background

In a generator set of a power plant, a large number of pins for positioning each component are provided, one end of each pin is provided with an internal thread, and the pin needs to be pulled out when the generator set is overhauled. Because the pin is generally tightly matched and connected with the parts, the pin is difficult to pull out, especially when the generator set is in a humid environment, the pin is easy to rust, and the rusted pin is difficult to pull out. The current tool for pulling out the pin is a screw and an iron hammer, a worker screws the screw into the pin, and the iron hammer is used for knocking the screw to pull out the pin. Firstly, the pin is pulled out by the existing tool, a worker needs to repeatedly swing a heavy hammer to knock the pin continuously, the working strength of the worker is obviously higher, the pulling-out efficiency is lower, the pin can be hammered on the hand of the worker, the worker is injured, and the safety is lower; secondly, the impact force generated by the hammer strike can cause the parts connected by the pin to be easily damaged. Therefore, the existing tool for pulling out the pin has the defects of high labor intensity of workers, low pulling-out efficiency, low safety and easy damage to parts of the generator set.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rotary pin pulling tool. With the utility model discloses extract the pin and have that workman intensity of labour is lower, extract efficiency higher, the security is higher and generating set spare part is difficult to impaired advantage.

The technical scheme of the utility model: the utility model provides a rotary pin pulling tool, includes the horizontally bearing plate, and the bottom of bearing plate both sides all is equipped with the backup pad, is equipped with the through-hole on the bearing plate, is equipped with the bolt in the through-hole, and the bolt is located between two backup pads.

In the above-mentioned rotary pin removing tool, the bolt is sleeved with a gasket.

In the above-mentioned rotary pin removing tool, the bolt is sleeved with a flat bearing.

In the aforementioned rotating pin pulling tool, the top of the bolt is provided with a rotating shaft, a horizontal cross rod is arranged on the rotating shaft, the cross rod penetrates through the rotating shaft, and the two ends of the cross rod are provided with anti-falling blocks.

In the above-mentioned rotary pin removing tool, at least one of the anti-dropping blocks is in threaded connection with the cross bar.

In the aforementioned rotary pin pulling tool, a sliding groove is formed in the bottom of the bearing plate, a sliding block connected with the supporting plate is arranged in the sliding groove, a reinforcing rib plate is arranged on the inner side of the supporting plate, and the top surface of the reinforcing rib plate is attached to the bottom surface of the bearing plate.

Compared with the prior art, the utility model has the advantages that the bolt drives the pin to move upwards and pull out, and the force required for rotating the bolt is smaller, so that the working strength of workers is lower; the pin can be pulled out only by continuously rotating the bolt without repeatedly swinging an iron hammer for knocking, so that the pulling-out efficiency is improved, the hammer is prevented from being damaged, and the safety is high; and the bolt can not be generated by impact force when being rotated, so that the part connected with the pin is not easy to be injured. Therefore, with the utility model discloses extract the pin have that workman intensity of labour is lower, extract efficiency higher, the security is higher and generating set spare part is difficult to impaired advantage.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example 1. The utility model provides a revolve formula instrument of pulling pin, as shown in fig. 1, includes horizontally bearing plate 1, and the bottom of bearing plate 1 both sides all is equipped with backup pad 2, is equipped with the through-hole on the bearing plate 1, is equipped with the bolt 3 of hexagon head in the through-hole, and bolt 3 is located between two backup pads 2.

And a gasket 4 is sleeved on the bolt 3.

The using method comprises the following steps: two backup pads 2 are located the both sides of pin respectively, push up on spare part, in the internal thread with the one end screw in pin of bolt 3, until changeing motionlessly, the rail of bolt 3 contacts with gasket 4 this moment, rotates bolt 3 with the spanner, and bolt 3 drives and drives the pin and rise, and the pin is deviate from completely.

The gasket 4 is used for preventing the bearing plate 1 from being worn and has the function of reducing the rotation resistance of the bolt 3 to a certain extent.

Example 2.
