[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] like Figure 1-9 As shown:

[0022] The present invention provides an installation and adjustment device for an instrument of a rotating equipment shaft system, comprising an instrument shaft 1, a shaft sleeve 2 and an installation and adjustment device for adjusting and installing the instrument shaft 1, wherein a nut 3 is arranged on the instrument shaft 1, and external threads are arranged at the upper and lower parts of the nut 3 on the instrument shaft 1, the shaft sleeve 2 is threadedly connected to the upper part of the nut 3 on the instrument shaft 1, and a protrusion 4 is arranged on the upper part of the shaft sleeve 2, characterized in that the installation and adjustment device comprises a mother component and a child component, the mother component is firstly sleeved on the instrument shaft 1, and then the child component is inserted into the mother component and sleeved on the shaft sleeve 2, during installation, the instrument shaft 1 is firstly pre-tightened on the rotating equipment by hand, and then the shaft sleeve 2 is pre-tightened on the instrument shaft 1 by hand, and then the mother component is sleeved on the instrument shaft 1, and the nut 3 on the instrument shaft 1 is rotated by the mother component to firmly fix the instrument shaft 1 on the rotating equipment, and then the child component is inserted into the mother component and sleeved on the shaft sleeve 2, and the child component rotates the shaft sleeve 2 to firmly fix the shaft sleeve 2 on the instrument shaft 1.

[0023] The female part includes a hexagonal nut wrench 5 and a female handle 6 arranged on the hexagonal nut wrench 5. The hexagonal nut wrench 5 is sleeved on the instrument shaft 1. The hexagonal nut wrench rotates the nut 3 on the instrument shaft 1 by horizontally rotating the female handle 6.

[0024] The sub-component includes a sleeve wrench 7 and a sub-handle 8 arranged on the sleeve wrench 7. A recess 9 is arranged inside the sleeve wrench 7. The sleeve wrench 7 is sleeved on the shaft sleeve 2 and the protrusion 4 is inserted into the recess 9. The shaft sleeve 2 is rotated by the sub-component so that the shaft sleeve 2 is firmly fixed on the instrument shaft 1.
