Generally, unique designs are carried out according to the place of use and product characteristics. For example, the patent announcement number is CN105751149B. A pin removal device of the present invention is provided with a fixing seat and a support rod, and one end of the fixing seat and the support rod is provided with a connecting rod correspondingly, the front end of one connecting rod is provided with a forward thread, and the front end of the other connecting rod is provided with a reverse The two connecting rods are connected by a fastener, the fastener is provided with a bow bracket, nuts are provided at both ends of the bow bracket, a positioning sleeve and a fixing nut are provided on the support rod, and a positioning screw is provided on one side of the fixing sleeve The positioning rod is provided with positioning grooves at intervals, the positioning rod passes through the lower end of the fixing sleeve and is provided with a positioning plate, the positioning rod is positioned through the positioning bolt and the positioning screw hole, the lower end of the disassembly screw is provided with a thimble clamp, and the fixing seat below the thimble A disassembly hole is provided, and a thimble is provided in the fixture. Another example is that the patent publication number is CN108000106A, a pin removal device or the like. However, these disclosed utensils and devices cannot satisfactorily satisfy the effective disassembly of the pins between the thrust head of the generator and the mirror plate. There is an insulating pad between the thrust head and the mirror plate. Every time the unit handles the axis, the insulating pad needs to be taken out. Before taking the insulating pad, the pin connecting the thrust head and the mirror plate needs to be pulled out. This type of pin is provided with a screw hole along the center hole, and the common method is to use the middle hole of the pin, put a crowbar into the hole, tap the crowbar lightly, loosen the pin, and then screw the screw into the pin hole, and pull out the screw way to remove the pin. There are obviously many shortcomings in this treatment method. For example, the person who pulls the pin stands on the thrust bearing seat, and this place is where the thrust oil tank is placed. If the pin is too tight and the pin cannot be pulled out with a crowbar and screw rod, it is necessary to use a bridge machine to pull the lifting ring. In this case, it is difficult to ensure the pulling out of the pin with a bridge machine. The concentricity between the pulling direction and the pin will easily cause serious damage to the screw hole of the thrust head pin, and the operation is cumbersome, requiring the cooperation of many personnel, which is laborious and laborious; in addition, during the process of beating the crowbar, it is also easy to damage the center screw hole of the pin, thus Cause deformation and damage of the pin.

In the aforementioned generator set thrust head and mirror plate pin removal tool, as a preference, an anti-skid pad is provided on the bottom surface of the support tube tripod.

This scheme is aimed at the characteristics of the pin between the thrust head and the mirror plate, that is, the pin is not only provided with a screw hole along the end of the center line in advance, but also has an insulating sleeve outside. If the pulling force is applied directly along the axial direction, due to the insulating sleeve The long-term interference fit between the pin and the connected body will cause the pin and the connected body to "melt" into one body. In actual operation, this direct pulling method should be avoided. In this plan, a double-headed screw is provided, one end of which is matched with the axial screw hole of the pin as the connection between the screw and the pin, and the other end controls the rotation of the screw through the booster nut rod, and is set between the pin and the booster nut rod. One piece of movable support tube tripod, the reinforced nut rod passes through the central guide hole of the support tube tripod, and the accommodation space with the opening of the support tube tripod facing downward can completely accommodate the pin from the outer diameter to the height; due to the reinforcement nut rod Setting, the booster rod can be lengthened according to the actual tightness, and the force-saving effect can be obtained by using the principle of leverage; A small amount of sliding occurs between the walls of the holes in the connecting body, thereby loosening the pin; then, maintaining this slight sliding of rotation and outward movement, all parts will not be damaged while the pin is completely taken out.

Further, the nut section of the double-ended screw rod that cooperates with the booster nut rod is a T-shaped screw rod to obtain a larger bearing capacity and an instantaneous pull-out stroke. Not only that, but in this technical solution, a pressure-bearing flat rotating shaft is provided at the bottom of the T-shaped nut at the middle position of the booster rod, which not only has the upper and lower pressure bearing capacity, but also provides the horizontal (actually perpendicular to the double-ended screw) rotation mode of the booster nut rod. The wheel is used to avoid surface-to-surface wear between the booster nut rod and the supporting surface of the support tube during rotation.

Moreover, this plan analyzes the actual operation situation on site. First, one end of the double-ended screw must be screwed into the screw hole of the pin to carry out the pin removal operation. However, the diameter of the support tube tripod is larger than that of the pin installation hole, which affects the operators on site. The line of sight, so there is a flat body on the top of the double-ended screw, which is helpful for the installation of the double-ended screw, and then the set of the support tube tripod.

Of course, the length of the T-shaped screw must be greater than the height of the accommodation space of the support tube tripod, and the height of the accommodation space of the support tube tripod must also be greater than the length of the pin, so as to meet the needs of the normal stroke during the pin extraction process.

Compared with the prior art, the beneficial effect of the utility model is: using the principle of lever and pitch micro-variable movement, a vertical force is designed to pull out the pin, so that the center of gravity of the operator is always on the same line as the axis of the pin, Prevent the operator from falling due to unstable center of gravity and ensure production safety; the structure is simple and the operation is convenient, only one person is required to operate, and it saves time and effort and is highly efficient; the entire operation process will not deform the pin and its surrounding objects And damage, to ensure the quality of maintenance.
