The invention provides a medical goose saw with a universal structure, which comprises a machine body; a motor is arranged in the machine body, and the front part of the machine body is provided witha goose saw installing head; a driving shaft is arranged between the motor and the goose saw installing head, and a universal rotating sleeve is arranged between the goose saw installing head and themachine body; a fixing buckle block is arranged on the universal rotating sleeve, and a buckle slot is arranged on the driving shaft; through cooperation of the fixing buckle block and the buckle slot, the direction of the goose saw installing head is adjusted; the lower end of the machine body is provided with a handhold handle, a storage battery is arranged in the handhold handle, and the motoris supplied with power through the storage battery. A saw piece is mounted through the goose saw installing head, and the fixing buckle block on the universal rotating sleeve is matched up with the buckle slot on the driving shaft, thus the direction of the goose saw installing head is adjusted as required, and the goose saw direction is further adjusted; the medical goose saw is convenient to carry out the processing work in other directions; through a rotate speed detector, the rotate speed of the goose saw in working is detected, and the working precision is improved.

The invention discloses a pipe sweeping device. The pipe sweeping device comprises a propeller and a sweeping head, wherein a backswept-shape conical ring sleeve is arranged on the side wall of the outer ring of the propeller, and the outer edge of the conical ring sleeve can be attached to the inner wall of a pipe fitting; the sweeping head can rotate in the axial direction of the sweeping head so as to sweep the inner wall of the pipe fitting; a flow passing channel is arranged on the propeller, a rotating mechanism is rotatably arranged in the flow passing channel, and the output end of therotating mechanism is movably penetrate through the flow passing channel, is located at one end of the sweeping direction, and is connected with the sweeping head through a universal structure; and when fluid in the pipe fitting passes through the flow passing channel, the fluid can drive the rotating mechanism to rotate, and the rotating mechanism drives the sweeping head to sweep the inner wallof the pipe fitting. According to the pipe sweeping device and the sweeping system, the sweeping head can be forced to automatically rotate and sweep the inner wall of the pipe fitting while the fluid is utilized to drive the whole device to move in the pipe fitting, the structure is simple, and the sweeping effect is good.

Disclosed is a primary line elasticity estimation method for ultimate bearing capacity analysis for a space circular tube structure. The primary line elasticity estimation method comprises the following steps of (1) establishing a space circular tube structure analysis model; (2) determining a failure unit; and (3) calculating the ultimate bearing capacity of the space circular tube structure through the primary line elasticity estimation method. By adoption of the primary line elasticity estimation method, the ultimate bearing capacity of the space circular tube structure can be accurately and rapidly solved; the shortcomings that a complex loading process and multiple times of increment iteration analysis are needed in solving the ultimate bearing capacity of the space circular tube structure by an elastic plastic increment analysis method in ultimate bearing capacity analysis for universal structures are overcome; and therefore, an efficient method is provided for evaluation of the overall security of the space circular tube structure.

The invention relates to a Tibetan character sequencing device and a method, and the device consists of a pretreatment sub-device, a syllable expansion sub-device, a sequencing element calling sub-device and a sequencing element string compression sub-device, wherein the pretreatment sub-device is used for carrying out appropriate decomposition on Tibetan syllable and Sanskrit transliterated Tibetan combined characters which do not conform to universal syllable structure, obtaining a syllable sequence and leading each syllable in the sequence to comfort to the universal structure; the syllable expansion sub-device is used for expanding the syllables which comfort to the universal syllable structure according to a particular order and obtaining a letter string which is equivalent to the original syllable orderliness; the sequencing element calling sub-device is used for calling a syllable element of each letter in an expansion equation and obtaining a sequencing element string; and the sequencing element string compression sub-device is used for carrying out reasonable compression on the sequencing element string. The device and the method can lead the sequencing result of all the Tibetan syllable and Sanskrit transliterated Tibetan combined characters to conform to the sequencing rules of a traditional Tibetan dictionary.

The invention discloses a coaxial linkage flexible mechanical arm based on a universal structure, which includes several cross shafts connected in series, a universal structure connecting adjacent cross shafts, and a power assembly. The pulley, the steel wire passing through the pulley, and the fixed part arranged on the cross shaft, the fixed part includes a first fixed part arranged on one side of the rotating shaft 1/rotating shaft 2, and a second fixing part arranged on the other side of the rotating shaft 1/rotating shaft 2 In the fixing part, the two ends of the steel wire are respectively connected with the first fixing part and the second fixing part. The coaxial linkage flexible manipulator based on the universal structure sets an easy-to-rotate universal structure between the cross shafts in series, and combines the power components composed of pulleys and steel wires interspersed between the cross shafts to make the manipulator The full-angle rotation can be realized conveniently, the principle is simple, the structure is light and handy, and the cost is low, and it can be applied to various fields such as industrial machinery automatic assembly, pipeline fault detection and repair.
