The invention discloses a flexible mounting mechanism for the tail end of a mechanical arm of a craniotomy operation robot, belonging to the technical field of medical apparatus and instruments. The flexible mounting mechanism comprises a skull milling fixedly connecting assembly, a tail end fixedly connecting assembly and springs, wherein the skull milling fixedly connecting assembly is used for fixedly connecting a skull milling part; the tail end fixedly connecting assembly is used for being fixedly connected with a flange at the tail end of the mechanical arm; the skull milling fixedly connecting assembly and the tail end fixedly connecting assembly are elastically connected through the springs, when a contact force is kept between the skull milling part and the bottom of the skull, the springs are in the compressed state, and thus the connection between the skull milling part and the tail end of the robot becomes flexible connection. For the flexible mounting mechanism, the flexible connection of the skull milling part and the flange at the tail end of the mechanical arm in the skull milling axial direction can be realized, and the rapid adjustment in the circumferential direction of skull drilling also can be realized.

The invention discloses a novel desert photovoltaic power station technology. A mounting frame is comprised. Accommodation cavities are symmetrically arranged on left and right sides in the mounting frame. A switch motor is fixedly arranged in the middle of the bottom wall in the mounting frame. Push-pull threaded rods are symmetrically arranged on left and right sides of the switch motor. The push-pull threaded rods are mechanically coupled with the switch motor. A push-pull sliding plate is arranged on each push-pull threaded rod, and the push-pull sliding plate and the push-pull threaded rod are in threaded connection. The device has the advantages of simple structure, convenient use and stable operation. When the weather is bad, a solar photovoltaic panel can be stored and protected. When the weather is fine, the sunlight can be used to the maximum by adjusting the orientation and angle of the solar photovoltaic panel.

The invention discloses an antenna adjustment device and method for a vehicle active RFID (Radio Frequency Identification) and a vehicle controller. The device is installed on a PCB (Printed Circuit Board) circuit board of the vehicle controller and the device comprises an RFID reader, an antenna, an antenna rotary table, a rotary shaft and a connection wire, wherein the RFID reader and the antenna are arranged on the antenna rotary table and the antenna rotary table is connected with the rotary shaft; the antenna rotary table drives the RFID reader and the antenna to rotate through the rotary shaft to realize the direction adjustment of the antenna; the RFID reader is connected with the PCB circuit board through the connection wire, wherein the RFID reader is used for receiving signals sent by an active RFID label through the antenna. The antenna adjustment device is provided with the active RFID label, the data transmission is not limited by the installation direction of the controller and the antenna adjustment can be carried out by the antenna adjustment device according to strength information of the received signals, so that the antenna can be adjusted to be best receiving direction.

The invention relates to the technical field of building construction, and discloses a deep foundation pit safety protection device for building construction and an installation method thereof. The device includes a supporting column, and a lifting cylinder is fixed inside the supporting column. The end is fixedly provided with a lifting support frame, and the top of the lifting support frame is fixedly provided with a protective plate, and both sides of the bottom of the protective plate are provided with a foundation pit pavement, and the bottom of one end of the foundation pit pavement is fixedly provided with a foundation pit fixed vertical plate. The invention provides top protection for the construction personnel at the bottom of the foundation pit through the construction protective sloping plate, and the rotating support plate can rotate on the rotating base to realize the orientation adjustment of the construction protective sloping plate. When debris falls into the foundation pit, it will be directly hit On the surface of the construction protection sloping plate, the construction protection sloping plate is forced to rotate, the buffer sleeve is pulled by the buffer connecting rod to move on the support beam, and the force is buffered by compressing the buffer spring to improve the protection effect on the top of the construction personnel.

The invention relates to a device and method for correcting a U-shaped pipe for an air conditioner condenser and evaporator fin automatic pipe inserting machine. The device comprises a machine frame, guide rails on two sides, a guide pin, a fixed supporting plate, a guide pin movable supporting frame, a guide pin push plate II, a guide pin push plate I, a guide pin drive cylinder and a lifting and horizontally-moving cylinder. The guide pin push plate I pushes the guide pin push plate II so that the guide pin which is locked by the guide pin push plate II and penetrates through the fixed supporting plate and the guide pin movable supporting frame can be inserted into a pipe opening of the U-shaped pipe after penetrating through a fin set, the guide pin play a good correcting role in the U-shaped pipe inserting work, and meanwhile the guide pin passively returns to the original position. The passive follow-up type U-shaped pipe correcting device corrects the U-shaped pipe to be freely and smoothly inserted through the guide pin, the resistance to the pipe inserting movement is reduced, the pipe inserting reliability is effectively ensured, the failure rate and the rejection rate are decreased, and the manufacturing cost is reduced.

The invention discloses an auxiliary platform for a small-size transformer of an urban distribution network, and the platform comprises a vehicle body and a sliding rail disposed on the vehicle body. The sliding rail is provided with a first translation mechanism and a second translation mechanism, which are parallel to each other. The first and second translation mechanisms are provided with a lifting mechanism, and the top of the lifting mechanism is provided with an inspection and maintenance platform. The front end of the inspection and maintenance platform is movably provided with an L-shaped suspension bracket, and the rear end of the vehicle body is provided with an L-shaped support. When the platform is used for the inspection and maintenance of a pole-type transformer, the platform can achieve the hoisting movement of specific equipment or parts, does not need to carry out the auxiliary operation of other hoisting equipment, prevents the additional hoisting equipment from participating, enables a worker to conveniently inspect and repair the transformer, and also improves the safety during inspection and maintenance. The inspection and maintenance platforms cooperate with each other for butt joint, so the platform can achieve the hoisting and installation of a transformer under the condition that a wire above the transformer is not disassembled, and is more flexible and convenient to use.
