The invention relates to a linear roller bearing comprising a guiding carriage (1) which can be mounted on a guiding rail (2) by means of rolls (7) and comprises at least one continuous roll channel (8) for the rolls (7). Said roll channel (8) comprises a carrier channel (9) for carrying rolls (7), a return channel (10) for returning rolls (7), and two deviation channels (11) which interconnect the carrier channel (9) and the return channel (10). The guiding carriage (1) comprises a carrier body (3) containing the return channel (10) and the carrier channel (9), and end parts (4) which contain the deviation channels (11) and are arranged on both front sides of the carrier body (3). The return channel (7) comprises a return pipe (11), the ends of said pipe being connected to the end parts (10). The roll channel comprises tracks for the rolls and lateral surfaces for laterally defining the roll channel. The return pipe (11) is provided with tongues (33) which engage in the end part (4), the facing tongue surfaces (34) forming the lateral surfaces (22) of the deviation channel (11). A separation joint (37) is arranged between each tongue (33) and the end limb (4) at least parallel to the return pipe (11).

The invention relates to a vertically lifting type antifreeze solution spraying device and a use method thereof and belongs to the technical field of mechanical design and control. The invention particularly relates to a technical scheme of an antifreeze solution spraying device which is capable of lifting vertically and can be used for efficiently and uniformly spraying the antifreeze solution onto five inner surfaces of a carriage of a coal train and a use method of the device. The antifreeze solution spraying device is characterized by comprising a support beam, a rotating beam, a verticallifting mechanism, a nozzle turning mechanism, a nozzle base assembly, an angular displacement sensing mechanism, a pipeline system and a control system. The antifreeze solution spraying device can uniformly spray the antifreeze solution onto the inner walls of the carriage in all directions, but stops spraying the antifreeze solution onto the clearances between carriages. When a high-altitude device, a head end and a maintenance car pass by, the whole antifreeze solution spraying device is lifted up vertically and stops spraying the antifreeze solution. The parameters, such as nozzle type, quantity, rotating speed, rotating direction and the like, can be automatically adjusted according to the conditions such as the indentified carriage position, moving direction, moving speed, ambient temperature and the like, thereby promoting the spraying effect, the spraying efficiency and the use ratio of the antifreeze solution.

The invention discloses a hinge. The hinge comprises a first rotary piece, a second rotary piece and a protective piece. The first rotary piece comprises a first connecting piece, a first rotary shaft and a first shaft sleeve. The second rotary piece comprises a second connecting piece, a second rotary shaft and a second shaft sleeve. The hinge is formed by splicing the first rotary piece, the second rotary piece and the protective piece. The protective piece of the proper length can be adopted for reducing the number of gaps between the first rotary piece, the second rotary piece and the protective piece, the gaps even can be prevented from being generated, and the technical effect that liquid matter in electronic equipment can be effectively prevented from leaking is achieved. Due to the fact that the hinge special for the electronic equipment can be composed of components which are lower in machining difficulty and simple in splicing manner, the technical effects that the production cost is effectively reduced and production and machining efficiency is improved are achieved.

The invention discloses an automated drilling device for pipes of multiple specifications. The automated drilling device comprises a base. The automated drilling device is characterized in that an output shaft of a longitudinal servo motor is linked with a ball screw, and the ball screw is supported by bearings and assembled onto the base; a workbench is further arranged above the base; a rolling guide rail is arranged between the workbench and the base; a mechanism for driving a conical clamp to rotate is arranged on the workbench; and the mechanism comprises support frames, a rotating servo motor, a reducer and a center height adjusting device. The device is provided with multiple adjustment mechanisms, and multiple holes can be drilled in the circumferential faces of the pipes large in length and diameter change range; the pipes move and rotate in the form of rolling friction, friction is reduced, rotation positions and movement positions are precise, and positional precision of all the holes drilled in the pipes is obviously improved; mounting of the pipes is completed one time, and the pipes do not need to be loosened in the intermediate process; and automation is achieved in the whole drilling process, and efficiency is obviously improved.

The invention discloses a method and a device for tracking control of solar electrical energy generation. The method comprises the following steps: automatically selecting a maximum power tracking mode or a timed tracking mode according to the level of the real-time output power of a solar battery; when the timed tracking mode is run, controlling tracking according to the current time and the detected current position signal of a solar panel; and when the maximum power tracking mode is run, determining the tracking direction of a mechanical structure according to the changing condition of the output power of the solar battery. The device comprises a centralized control module, a position detecting module for detecting the actual rotating position of the solar panel, and an array detecting module for detecting the real-time output power of the solar battery. The invention has the advantages of simple and convenient operation, accurate rotating position, realization of automatic control, simple structure, high detecting accuracy and low cost.

The invention relates to a spraying equipment, in particular to a high-reflectivity powder coating spraying equipment for lamp production. The technical problem of the present invention is to provide an automatic spraying lamp, a high-reflectivity powder coating spraying equipment for lamp production with good spraying effect and simple operation. The technical solution of the present invention is a high-reflectivity powder paint spraying equipment for lamp production, including: a base; a first support plate, the first support plate is provided in the upper middle of the base; a motor is provided on one side of the upper middle of the base; The transmission assembly is provided with a transmission assembly on one side of the upper middle part of the base. The beneficial effect is: under the action of the intermittent rotating component, people place the lamp on the shelf, start the motor, and after a series of transmissions, the third transmission rod will drive the first contact rod to rotate 90 degrees, and the first contact rod will rotate 90 degrees. When in contact with the touch switch, the nozzle will spray the paint onto the lamp, which effectively improves people's work efficiency.
