Example

With reference to Fig. 1-3, a maintenance maintenance box of a thermal power plant steam turbine comprises a rectangular box body 1, a cavity 2, a tray one 3, a tray two 4, a tray three 5, a tray four 6, a manual hydraulic cylinder 10 and a base 11, Among them: the upper surface of the rectangular box 1 is provided with a concave cavity 2 for placing tools and parts. Through the setting of the concave cavity 2, when the maintenance work of the steam turbine in the thermal power plant is carried out, the used tools and parts can be temporarily stored. Placed in the concave cavity 2 to prevent loss of tools and parts, and the four surfaces of the rectangular box 1 and the concave cavity 2 are vertically slid from high to low and installed with tray one 3, tray two 4, and tray three 5 And tray 4 6, because tray 1 3, tray 2 4, tray 3 5 and tray 4 6 are set from high to low, so when they are opened and closed, they do not affect each other, making it more convenient and flexible. The rectangular box body 1 is rotatably connected with the output end of the manual hydraulic cylinder 10. Through the setting of the manual hydraulic cylinder 10, it is convenient to adjust the height of the rectangular box body 1 when the maintenance work of the steam turbine in the thermal power plant is carried out. The place and different maintenance personnel are used; the tail end of the manual hydraulic cylinder 10 shell is fixedly connected with the base 11 through bolts, and the setting of the base 11 can ensure the stability of the whole when in use.

Rectangular box body 1 and recessed cavity 2 are vertical four faces and are provided with hidden cavity 18 respectively from high to low, by the setting of hidden cavity 18, when not in use, can put tray one 3, tray two 4, tray Tray 3 5 and Tray 4 6 are hidden inside the rectangular box 1, thereby reducing the footprint and preventing dust from accumulating in Tray 1 3, Tray 2 4, Tray 3 5 and Tray 4 6, and each hidden cavity Each drawer guide rail is fixedly installed in the inside of 18, and the fixed part of each drawer guide rail is fixedly connected with one side of each hidden cavity 18 inside by bolt, and the movable part of each drawer guide rail is connected with each tray one 3, tray two 4, One side of tray 3 5 and tray 4 6 is fixedly connected. Through the setting of drawer guide rails, the stability of tray 1 3, tray 2 4, tray 3 5 and tray 4 6 can be guaranteed. Two 4, tray three 5 and tray four 6 carry out spacing, prevent tray one 3, tray two 4, tray three 5 and tray four 6 from protruding from each hidden cavity 18, and each hidden cavity 18 respectively passes through drawer guide rail and corresponding The tray one 3, tray two 4, tray three 5 and tray four 6 are slidingly connected; the bottom surface of the rectangular box 1 is fixedly equipped with a rotating mechanism; the rotating mechanism includes a connecting platform 7, a sleeve 8 and a fixed platform 9, and the connecting platform 7 The top of the top is fixedly connected with the bottom surface of the rectangular box 1 by bolts, and the bottom end of the connection table 7 is fixedly connected with the top end of the sleeve 8 by bolts; The arrangement of the structure between the cylinder 8 and the fixed table 9 can make the rectangular box 1 rotate 360 degrees around the center of the manual hydraulic cylinder 10, so that when the operator needs to take the tools inside the pallet far away from him , you only need to turn the rectangular box 1, you can make the pallet far away from you close to you, reducing the movement of the operator, so that it is more convenient and efficient, and the bottom surface of the fixed table 9 is connected with the output of the bolt and the manual hydraulic cylinder 10 End fixed connection.

Tray 1 3, tray 2 4, tray 3 5 and tray 4 6 are each provided with a handle groove 16 for applying force. Push and pull with pallet four 6.

The outside of the sleeve 8 is threadedly installed with positioning bolts 17 for fixing, and the inner end of the positioning bolts 17 passes through the sleeve 8 and contacts the peripheral surface of the fixed table 9. Through the setting of the positioning bolts 17, when the rectangular box is not needed When the body 1 rotates, the fixing table 9 can be squeezed by the positioning bolt 17, thereby ensuring the stability of the whole.

One side above the base 11 is fixed with a push bar 12 by bolts, and the top of the push bar 12 is fixed with a handle 13 by bolts; each corner of the base 11 is fixed with an integral fixed ear 14, and The bottom of each fixed ear 14 is respectively fixed with the universal wheel 15 that has brake by bolt, by the setting of push bar 12, handle 13 and each universal wheel 15, it is convenient for the operator to push the whole body to the place by handle 13. desired location.

In this embodiment, when the maintenance work of the steam turbine in the thermal power plant is carried out, first the required tools are placed in tray one 3, tray two 4, tray three 5 and tray four 6, so that when in use , push the whole body to the desired position through the handle 13, and then lock the universal wheels 15 through the brakes of the universal wheels 15 to prevent them from moving by themselves. At this time, the rectangular box is adjusted by the manual hydraulic cylinder 10 according to the maintenance requirements 1 height, and then through the handle groove 16, tray one 3, tray two 4, tray three 5 and tray four 6 are all drawn out from the rectangular box body 1. At this moment, all tools will be in a panoramic view, thereby facilitating The operator takes it. When the operator needs to take the tool inside the pallet far away from him, he only needs to loosen the positioning bolt 17 to turn the rectangular box 1 so that the pallet far away from him is close to him. , that is, the positioning bolt 17 can be tightened again to fix it, so as to prevent it from rotating by itself, thereby reducing the movement of the operator and making it more convenient, flexible and efficient.

Utilize the technical solution described in the utility model, or those skilled in the art design a similar technical solution under the inspiration of the technical solution of the utility model, and achieve the above-mentioned technical effects, all fall into the protection scope of the utility model.
