The invention discloses an inspection and maintenance device for an industrial robot, which comprises an inspection table, a support frame is welded at the bottom of the inspection table, a mounting plate is fixedly connected to the inner side of the support frame, and a scissor lift is fixedly installed on the top of the mounting plate. platform, the scissor lift platform runs through the maintenance platform, and both sides of the maintenance platform are fixedly connected with a first hinged seat, and a hydraulic cylinder is hinged on one side of the first hinged seat, and the hydraulic cylinder is far away from the first hinged One end of the seat is fixedly connected with a second hinged seat, an expansion board is hinged at the back of the inspection platform, and the expansion board is fixedly connected with the second hinged seat, and a drive slot is provided on the front of the inspection platform. The invention solves the problem that because the robot is difficult to move, maintenance personnel need to walk back and forth during maintenance, and the area of ​​the maintenance platform cannot be changed. When the robot for maintenance is large, the robot cannot be placed on the platform, which affects the maintenance problems with work.

The invention provides a boiler overhaul device suitable for a workshop of a thermal power station, and relates to the technical field of boiler overhaul. The boiler overhaul device suitable for a thermal power station workshop includes a furnace body. Guide rails are fixedly installed on the outer periphery of the upper and lower sides of the furnace body. The outer periphery of the guide rail is provided with a chute, and the inner side of the chute in the guide rail is rollingly connected There are balls, and an upper mounting plate and a lower mounting plate are slidably connected to the outer periphery of the guide rail respectively, and the inner sides of the upper mounting plate and the lower mounting plate are fixedly installed with a limiting plate. The boiler overhaul device suitable for the workshop of thermal power station enables the staff to climb upwards on the periphery of the boiler, which is more labor-saving and safe, and can directly face the surface of the boiler, which is convenient for overhauling the surface of the boiler and can be close to all parts of the boiler. The outer surface avoids the construction of scaffolding, which saves time and effort. After use, the pedal will fold and shrink to the left again, reducing the occupied area.

The invention relates to the technical field of generator set testing, in particular to a device for checking the fuel injection status of a fuel injector in a generator set target test, including a high-pressure ball head oil pipe and an oil pump, and one end of the high-pressure ball head oil pipe is connected to the fuel injector through a hollow oil pipe bolt The position of the oil plug; the oil outlet end of the oil pump is connected to the other end of the high-pressure ball head oil pipe, and the pipeline at the oil inlet end of the oil pump leads into the machine oil. A method for inspecting the fuel injection status of a fuel injector in the target shooting test of a generator set, using the aforementioned device for checking the fuel injection status of the fuel injector in the target shooting test of a generator set. This patent can conveniently check the fuel injection status of the fuel injector when the machine is not turned on, which can greatly avoid the problem of the fuel injector causing the unit to pull cylinders, and greatly promote the comprehensiveness of maintenance and the reliability of the equipment.

An embodiment of the present invention provides a method for opening a shield machine under normal pressure. The method for opening a shield machine under normal pressure includes the following steps: setting a plurality of hollow piles arranged at intervals along a preset direction at a preset opening position, Among them, the preset direction has an included angle with the tunneling direction of the shield machine; the shield machine tunnels to the preset opening position, and the cutter head of the shield machine extends into multiple hollow piles; the multiple hollow piles are located on the outermost side The two hollow piles are respectively the first hollow pile and the second hollow pile, and the orthographic projection of the front end face of the cutter head along the direction parallel to the axis of the hollow pile has a first part located in the first hollow pile and a first part located in the second hollow pile. In the second part, the length of the first part is different from the length of the second part; open the warehouse at normal pressure. The opening of the shield machine under normal pressure has high safety, and there is enough room for movement to carry out the inspection and maintenance of the shield machine.

The invention discloses a dual-motor power synthesis device for driving an electric vehicle, specifically relates to the technical field of electric vehicle transmission, and comprises a front rod and a front wheel. Two sets of front wheels are fixedly connected to both sides of the front rod. The present invention is provided with crawler belt, first bearing, first gear, variable speed motor and third gear, and when the device is started, it uses variable speed motor, first gear and third gear to drive the rolling of the front wheel and rear wheel, and needs to change speed At the same time, only need to control the two groups of variable speed motors to synchronously shift to a certain value, and the speed change of the vehicle can be realized. The variable-speed motor on one side can be turned off, and only the variable-speed motor on the other side can be turned on. The whole process can be completed by controlling the motor. It is simple and easy to operate, and solves the inconvenience of variable speed and steering in the existing dual-motor synthesis device. question.
