Description

[0001] The invention relates to the technical field of maintenance tools for hydropower stations, and in particular to a mobile operating vehicle for use at a maintenance site of a hydropower station. The mobile operating vehicle at the maintenance site is used for carrying a variety of tools during maintenance. Background Art

[0002] When performing maintenance work at a hydropower station, maintenance personnel often need to carry a large number of large and diverse tools, especially when performing large-scale maintenance work, which requires the use of various types of instruments and meters for a long time. In previous work, on-site maintenance personnel often use a combination of multiple tools to achieve this. These tools often have relatively single functions, and there are obvious differences in the choice of tools for electrical work and water machine work. All of these have led to maintenance personnel needing to do a lot of preparation work before maintenance work. Therefore, it is necessary to invent a mobile work vehicle for maintenance sites.

[0003] In the prior art, China's authorized patent announcement number: CN 118046354 A discloses that the present invention relates to the field of nuclear power maintenance tools, and in particular to a mobile work platform for maintenance sites. The mobile work platform includes: a main desktop structure, a folding rod, stool legs, a cart bottom structure, a push rod, and a stool surface; a folding rod is provided between the main desktop structure and the cart bottom structure, and the side of the cart bottom structure is connected to a push rod, and the bottom is connected to a universal wheel; when stored, the stool legs and the stool surface are respectively fixed in the cart bottom structure; when working, the stool legs and the stool surface are assembled into a complete stool. The mobile work platform for maintenance sites of the present invention can be used as a tool cart in a folded state, and can be used as a temporary workbench after unfolding, which optimizes the on-site working environment and working process. It can effectively solve the problems of lack of working platforms and limited space on site. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 5 As shown, it shows a schematic diagram of the structure of the present invention, including: a box body 1, wheels 2 and a handle 3;

[0037] The wheels 2 are located at the bottom of the box 1. There are four wheels 2, which are respectively placed at the four corners of the bottom of the box 1.

[0038] The handle 3 is arranged at the upper end of the box body 1;

[0039] Drawer modules of different specifications are provided inside the box 1 , and the drawer modules are pushed, pulled, fixed and locked in position by a connecting rod lock 14 .

[0040] The wheel 2 is provided with a foot brake pedal 8, and the foot brake pedal 8 locks and brakes the wheel 2 by stepping down the pedal, and starts the wheel 2 by pulling up the pedal; the wheel is a universal wheel.

[0041] The rear side panels of the box body 1 are unfolded to form an unfolding platform;

[0042] The rear side plate of the box body 1 is fixed to the unfolding platform by the support rod 5 during use, thereby forming a temporary operating platform;

[0043] After the unfolding platform 4 is unfolded, the folding stool 6 is hung and placed by the hook 7 .

[0044] The drawer module comprises a parts drawer 10, a power tool drawer 11, an insulating tool drawer 12 and an instrument box drawer 13;

[0045] Drawers of different specifications and models of the drawer module are provided with drawer handles 9.

[0046] The drawer handle 9 is embedded.

[0047] The connecting rod lock 14 is arranged between the drawers of different specifications and models, and the connecting rod lock is used to fix the position of the drawer side frame.

[0048] The connecting rod lock 14 includes an upper rod 141, a lower rod 142 and a locking piece 143. The upper rod 142 is connected to the lower rod 143 through the locking piece 143 in the middle. The left end of the locking piece 143 is fixedly connected to the upper rod 141 by screws, the right end of the locking piece 143 is fixedly connected by screws, and the middle of the locking piece 143 is connected to the drawer by screws.

[0049] The linkage lock 14 pivots between a secured and a released position.

[0050] The present invention is specifically implemented as follows: first, before entering the maintenance site, the staff puts the required tools into the drawer module according to the tool type. At this time, the drawer is in an open state, and the connecting rod lock is in a stretched state. After the tools are put in, the drawer is put into the box. At this time, the connecting rod lock is in a tightened state, and the drawer module is fixed by the connecting rod lock; the mobile work cart is pushed to the maintenance location through the handle on the side. After reaching the maintenance location, the staff stops the mobile cart in place by stepping on the foot brake pedal of the wheel, and then maintenance work can be carried out. The side panels of the mobile cart can be unfolded, and the side panels are fixed and supported by the support rods, thereby forming a temporary unfolding platform. If the space at the maintenance site is limited, the staff can operate on the unfolding platform.
