Description

Locating pin extraction tool for large equipment

technical field

The utility model belongs to the field of petroleum machinery, in particular to a tool for pulling out positioning pins of large-scale equipment.

Background technique

Large-scale mechanical equipment is usually fixed on the ground or the platform by positioning pins. For large-scale mechanical equipment fixed outdoors, the positioning pins are difficult to pull out due to corrosion, shaft and damage during maintenance, and the working time for pulling out the pins is long. , Low efficiency and easy to damage the positioning pin thread. And there is no tool specially designed for dismounting the positioning pin at present.

Contents of the invention

The purpose of the utility model is to solve the current problem of lack of positioning pins specially used for dismantling large-scale mechanical equipment, and provide a tool for pulling out large-scale equipment positioning pins.

The tool for pulling out positioning pins of large-scale equipment includes a frame body bracket, a first through hole is opened on the bottom of the frame body bracket, a screw hole is opened on the top of the frame body bracket, a screw rod is fitted in the screw hole, and a nut is fixed on the upper end of the screw rod; It includes a pin body bracket, the pin body bracket is located inside the frame body bracket, the lower end of the screw rod is connected with the top of the pin body bracket through a tapered thrust bearing, and the bottom of the pin body bracket corresponds to the position of the first through hole. Two through holes.

The utility model has the following beneficial effects:

When the positioning pin extraction tool for large-scale equipment is in use, first use a wrench to turn the screw rod to drop the pin body support to the bottom of the frame body support, then place it on the platen, and let the positioning pin pass through the first through hole and the through hole at the same time. The second through hole, and then fix the nut on the top of the positioning pin, and finally turn the screw to lift the pin body bracket, and the pin body bracket can pull the positioning pin out of the pin hole on the platen. The whole process only takes 20 minutes. Compared with the 40 minutes required by the traditional method, the work efficiency is greatly improved, and at the same time, there is no damage to the positioning pin and the body. The utility model has the advantages of simple structure, easy operation, high efficiency and reusable positioning pins pulled out.

detailed description

Below in conjunction with Fig. 1, the utility model is further described:

The positioning pin extraction tool for large equipment includes a frame support 1, the bottom of the frame support 1 is provided with a first through hole 2, and the top of the frame support 1 is provided with a screw hole, and the vertical position of the screw hole is consistent with that of the first through hole. The positions of 2 correspond to each other, and the screw hole is equipped with a screw 3, that is, the screw 3 passes through the screw hole, and the upper end of the screw 3 is fixed with a nut 4. With the above structure, the construction personnel can clamp the nut 4 with a wrench to realize the rotation of the screw 3 . Also comprises pin body support 5, and pin body support 5 is positioned at the inner side of frame body support 1, and the lower end of described screw rod 3 is connected with the top of pin body support 5 through conical thrust bearing 6, namely the outer cover of conical thrust bearing 6 It is fixed with the pin body bracket 5, and the inner sleeve of the tapered thrust bearing 6 is fixed with the lower end of the screw rod 3. With the above structure, the tapered thrust bearing 6 can reduce the distance between the screw rod 3 and the pin body bracket 5 during the rotation of the screw rod 3. friction between them while improving durability. The bottom of the pin bracket 5 is provided with a second through hole 7 at a position corresponding to the first through hole 2 .

When the tool for pulling out positioning pins of large equipment is in use, first turn the screw rod 3 with a wrench to drop the pin body support 5 to the bottom of the frame body support 1, then place it on the platen 8, and let the positioning pins 9 pass through at the same time The first through hole 2 and the second through hole 7, then the top of the positioning pin 9 is fixed with a nut, and finally the screw rod 3 is rotated to promote the pin body support 5, and the pin body support 5 can remove the positioning pin 9 from the position on the platen 8. The whole process of pulling out the pin hole only takes 20 minutes, which greatly improves the work efficiency compared with the 40 minutes required by the traditional method, and at the same time, there is no damage to the positioning pin and the body. The utility model has the advantages of simple structure, easy operation, high efficiency and reusable positioning pins pulled out.
