Embodiment 1

[0039] Such as Figure 1-Figure 8 As shown, the present invention solves the method for unloading of construction machinery connection parts, comprising the following steps:

[0040] Step A Installation: Put the pin shaft 5 through the gear 6 from the axis of the gear 6, fix the gear 6 on the pin shaft 5, and connect one end of the anti-loosening plate 4 to the side wall of the pin shaft 5, and then install the pin shaft 5 It is hinged with the end surface of the screw rod of the bolt 1 away from the head of the bolt, so that the pin shaft 5 can rotate around its own axis;

[0041] Step B Fixing for the first time: first put the parts to be connected and fixed, and align the threaded holes on them, then insert the anti-loosening plate 4 and the end of the bolt 1 close to the anti-loosening plate 4 into the threaded holes in turn, and then Rotate the bolt 1 to thread the bolt 1 to the threaded hole, and fix the parts to be connected and fixed to each other;

[0042] Step C Se...

Embodiment 2

[0045] The present invention is based on embodiment 1, and the present invention is further described.

[0046] Such as Figure 1-Figure 8 As shown, the present invention solves the method for loosening and unloading the connection parts of construction machinery. The push rod assembly includes the stopper 2, the installation shaft 8, the spring 9 and the connection shaft 10 connected in sequence, and the installation shaft 8, the spring 9 and the connection shaft 10 are coaxial with each other, and the end surface of the connecting shaft 10 away from the spring 9 is hinged with the anti-loosening plate 4;

[0047] A relief groove 11 is provided at the head of the bolt 1, and the projected dimension of the relief groove 11 along the axis of the bolt 1 is consistent with the projected dimension of the stopper 2 along the axis of the installation shaft 8;

[0048] One end of the relief groove 11 close to the screw rod is provided with a mounting hole 12 communicating with the b...

Embodiment 3

[0050] The present invention is based on embodiment 2, and the present invention is further described.

[0051] Such as Figure 1-Figure 8 As shown, the method of the present invention to solve the loosening of the connection parts of construction machinery also includes step D and step E which are sequentially arranged after step C;

[0052] Step D pushing: when the surface of the anti-loosening plate 4 away from the axis of the bolt 1 is in contact with the parts to be connected, continue to push the push rod assembly along the axis of the bolt 1, and the spring 9 is compressed until the stopper 2 moves to the installation hole 12 in;

[0053] Step E rotation: when the block 2 moves into the mounting hole 12, turn the block 2 so that the projection of the block 2 along the axis of the bolt 1 does not completely fall on the relief groove 11, that is, the block 2 is installed in the hole 12 Block the end face away from the end of the screw.

[0054] When the push rod assemb...

Abstract

The invention discloses a method for solving looseness of connecting parts of engineering machines. The method comprises the following steps that 1, a hinge pin is made to penetrate through a gear, the gear is made to be fixed to the hinge pin, one end of an anti-loosening plate is connected with the side wall of the hinge pin, and then the hinge pin is hinged to the end face, far away from the head of a bolt, of a screw of the bolt; 2, parts to be fixedly connected are well placed, threaded holes in the parts are aligned with each other, the anti-loosening plate and the end, close to the anti-loosening plate, of the bolt sequentially penetrate through the threaded holes, the bolt is rotated, and the parts to be fixedly connected are mutually fixed; and 3, one end of a pushing rod assembly is inserted into a through hole, a rack is meshed with the gear, the gear moves along the axis of the bolt along with the rack, and the anti-loosening plate rotates around the axis of the hinge pin. The anti-loosening plate limits movement of the bolt along the axis when bolt looseness occurs, the situation that the bolt is loosened due to vibration of the engineering machines is avoided, maintenance frequency of the engineering machines is reduced, and related engineering accidents are avoided.

Description

technical field [0001] The invention relates to a method for placing and loosening a connection part, in particular to a method for solving the problem of loosening and unloading a connection part of construction machinery. Background technique [0002] A fastening device is mainly used for connecting two or more parts. Common devices include bolts, screws, rivets, etc. In petroleum engineering machinery, bolts, screws, etc. are used to fix the connection parts through threads. As the construction machinery performs related operations, the threaded connection part receives vibration and transmits the vibration to the bolts. The threaded connection between the two parts will cause the bolts to loosen and unload continuously during vibration, resulting in instability of the connection part of the construction machinery. This not only increases the maintenance frequency of construction machinery, but the bolts are completely loosened, and related parts fall off, which will ca...
