Description

A thrust pad disassembly tool

technical field

The utility model belongs to the field of power generation equipment, in particular to a thrust tile disassembly tool for disassembling thrust tiles in a generator set

Background technique

In the generator set, the thrust tile supports the rotating part of the unit. Since the overall weight of the thrust tile is large and there is little space for disassembly or installation of the thrust tile in the unit, it is very difficult to install it by manpower. In order to solve the above-mentioned difficulties, most of the existing thrust tiles enter the inside of the unit for disassembly or installation through special tools from the side opening of the unit (the lower end of the side opening has a distance from the ground). The special tools include a rectangular platform on which the thrust tile is placed. Balls are densely covered on the platform. There are two short adjustment feet at the front end and two long adjustment feet at the rear end under the platform; Push it into the interior of the unit from the side opening of the unit, put the short adjustment foot on the internal structure of the unit, and the long adjustment foot on the ground outside the unit, then hoist the thrust tile on the platform and push it into the unit through the ball When disassembling, since the surface formed by the top of all the balls on the platform must be at the same height as the thrust tile bottom plane and be in a horizontal state, special tools need to go in and out of the unit several times to adjust the short adjustment feet and long adjustment feet. Adjusting the height of the feet, and because the four feet are independent of each other, it is very difficult to adjust the platform to a horizontal state; all of the above have caused the thrust tile disassembly operation to be cumbersome and inefficient.

Therefore, using the existing special tools to disassemble the thrust pad has the disadvantages of cumbersome operation and low efficiency.

Utility model content

The purpose of the utility model is to provide a thrust pad disassembly tool. The disassembly and assembly of the thrust tile by the utility model has the advantages of convenient operation and high efficiency.

The technical scheme of the utility model: a tool for disassembling and assembling thrust tiles, including a platform, on which balls are arranged, and two sets of parallel adjustment mechanisms are arranged below the platform, and the adjustment mechanisms include two sets of front and rear four-bar linkages, four linkages The mechanism includes four connecting rods hinged into a rhombus through the first, second, third and fourth hinged shafts sequentially, wherein the first hinged shaft is connected with the bottom surface of the platform; wherein the third and fourth hinged shafts are respectively provided with screw threads The nuts facing the opposite direction; the four nuts on the front and rear two groups of four-bar linkages are connected through a screw rod with a turning handle at the end; the bottom of the four-bar linkage close to the turning handle is provided with a third hinge. Shaft-attached height adjustment feet.

In the aforementioned thrust shoe dismounting tool, the adjustment mechanism is far away from the four-bar linkage mechanism of the turning handle, and the third hinge shaft included in it is provided with a roller.

In the aforementioned thrust shoe disassembly tool, the height adjustment foot includes an outer tube connected to the corresponding third hinge shaft, and a coaxial bolt screwed to the bottom of the outer tube is provided.

In the aforementioned tool for removing and assembling the thrust pad, the outer tube is covered with a bushing, and the bushing is connected to the bottom surface of the platform through a support rod inclined to the inner side of the platform.

In the aforementioned thrust pad dismounting tool, a nylon spacer is provided below the bolt.

Compared with the prior art, when the utility model is turning the handle, the front and rear two groups of four-bar linkages of the adjustment mechanism can move at the same time and produce the same height change. Therefore, when the utility model is pushed away from the end of the handle The unit can be adjusted directly after entering the unit, and it does not need to enter and exit the unit multiple times to adjust, which saves time; the utility model only needs to adjust two height adjustment feet when adjusting the level, which is simpler and easier than the four-leg adjustment of special tools Many; the utility model is operated like this: (1) roughly adjust the height of the height adjustment foot so that the bottom surface of the platform is slightly higher than the lower end surface of the side opening of the unit; Push it into the unit; (3) adjust the two height adjustment feet to make the platform in a horizontal state; (4) rotate the two turning handles at the same time to make the top of the ball on the platform consistent with the height of the bottom of the thrust tile.

Therefore, the disassembly and assembly of the thrust pad by the utility model has the advantages of convenient operation and high efficiency.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for limiting the utility model.

Example. A thrust tile disassembly tool, as shown in Figure 1, Figure 2 and Figure 3, includes a platform 1 formed by welding square tubes, on which a ball 2 is arranged, and the ball 2 is connected to the platform 1 through a ball cage 20, and the platform 1, there are two sets of parallel adjustment mechanisms 3, the adjustment mechanism 3 includes two sets of four-bar linkages 4, the four-bar linkage 4 includes the first hinge shaft 5, the second hinge shaft 6, and the third hinge shaft 7 and the fourth hinge shaft 8 are hinged into four rhombus-shaped connecting rods, wherein the first hinge shaft 5 is connected to the bottom surface of the platform 1 through a bracket 19; wherein the second hinge shaft 6 and the fourth hinge shaft 8 are respectively provided with screw threads Opposite nut 9; Four nuts 9 on the front and back two groups of four-bar linkages 4 are provided with the screw rod 11 of turning handle 10 to run through and connect by an end; The height adjustment foot 12 that is connected with the third articulation axis 7 that it comprises.

In order to push the utility model into the interior of the unit conveniently, the adjustment mechanism 3 is far away from the four-bar linkage mechanism 4 of the rotating handle 10, and the third hinged shaft 7 contained therein is provided with a roller 13.

The height-adjusting foot 12 includes an outer tube 14 connected to the corresponding third hinge shaft, and a coaxial bolt 15 screwed thereto is arranged under the outer tube 14 .
