Assembly concrete new type pillar and beam structure and assembly connecting method

InactiveCN104727439Areduce in quantityReliable connection force transmission
The invention relates to the field of assembly concrete buildings, in particular to an assembly concrete new type pillar and beam structure and an assembly connecting method. Assembly concrete new type pillars and an assembly concrete new type beam can serve as pillars and a beam applied to the assembly concrete buildings. The assembly concrete new type pillar and beam structure comprises a prefabricated pillar and prefabricated beam structure, and each prefabricated pillar comprises a prefabricated side pillar and a prefabricated center pillar. Grouting grooves are formed in the top and the bottom of each prefabricated pillar, and the connected grouting grooves are grouted with a grouting material to achieve equal-shearing-strength connection between the prefabricated pillars; as beam steel bar penetrating holes are reserved in the prefabricated pillars, prefabricated beam steel bars can directly penetrate through the prefabricated pillars to be connected with the prefabricated pillars; as steel poles provided with threads at the ends are pre-buried in the prefabricated beam to transmit shearing force and pull force between the prefabricated beam and post-poured concrete, and the steel poles with the threads at the ends can serve as connecting pieces for fixing a prefabricated slab to the prefabricated beam. By the adoption of the method, connection between precast concrete members is more reliable and economical.

Online demonstration method for 'J'-shaped groove welding robot

ActiveCN102581444Areduce in quantitySolve the quick positioning
The invention discloses an online demonstration method for a 'J'-shaped groove welding robot, which relates to the field of robot welding, and includes the steps: judging whether circumferential deviation is within a first preset range or not by a microprocessor, acquiring axial deviation if the circumferential deviation is within the first preset range, and if the circumferential deviation is not within the first preset range, rectifying the circumferential deviation by the microprocessor, and acquiring a first practical weld shape track; and judging whether the axial deviation is within a second preset range or not by a microprocessor, if the axial deviation is not within the second preset range, rectifying the axial deviation by the microprocessor, and acquiring a second practical weld shape track or a third practical weld shape track, and if the axial deviation is within the second preset range, leading the J-shaped groove welding robot to return to a start point again, turning off a laser range finder and starting to weld so as to complete the process. The online demonstration method for the 'J'-shaped groove welding robot has the advantages that the quantity of weld characteristic data points are obviously decreased by means of B-spline interpolation, the problem of quick positioning of a robot-based coordinate system and a workpiece coordinate system is fundamentally solved by means of judgment and deviation rectifying of the microprocessor, human factor influence on demonstration is reduced, and weld quality consistency is guaranteed.

Multifunctional bed-chair integrated robot

ActiveCN105816282AHigh degree of digitizationreduce in quantity
The invention relates to the technical field of nursing machinery, and discloses a multifunctional bed-chair integrated robot which comprises a bed body part (1), a wheel chair part (2) and a moving chassis part (3), wherein the wheel chair part (2) and the bed body part (1) are in butt joint to form a widened nursing bed when being used as a nursing bed; the wheel chair part (2) and the bed body part (1) are horizontally separated when being used as a wheel chair; the wheel chair part (2) is arranged on the moving chassis part (3); the moving chassis part (3) is provided with an independent drive for driving the wheel chair to walk. The multifunctional bed-chair integrated robot consists of two parts, namely, the bed body part and the wheel chair part, and the wheel chair part can be composed of an intelligent moving chassis and an upper wheel chair part. The wheel chair part and the bed body part are automatically connected and separated in a butt joint manner through bolts and bolt pins, the whole body formed through butt joint of the wheel chair part and the bed body part still has a nursing function, and meanwhile the battery of the wheel chair part can be automatically charged after butt joint; the multifunctional bed-chair integrated robot is high in digitalization degree, the number of nursing operators is reduced, and the nursing quality to patients is improved.

Multi-channel soft abdominal wall working window

InactiveCN101617932Areduce in quantityConvenient for surgical work
The invention relates to medical apparatus and instruments, in particular to a multi-channel soft abdominal wall working window utilized in match with a laparoscope, the function thereof is equal to a laparoscope puncture cannula. The working window is a convergent of puncture cannulas, and is used for realizing single-hole laparoscope surgeries. The main body of the multi-channel soft abdominal wall working window is a column-shaped gas pocket or a dumbbell-shaped air pocket with two expanding ends; the column-shaped gas pocket is provided with at least more than two vertical work channels and gas tubes, when in use, the column-shaped gas pocket is put into an abdominal wall hole and is charged by the gas tubes; the charged column-shaped gas pocket is extruded with the abdominal wall to prevent the gas in the abdominal cavity from leaking outside; after the gas pocket is fully charged in the gas pocket, a work channel on the column-shaped gas pocket is extruded to be in a close state to prevent the gas in the abdominal cavity from leaking outside; the laparoscope and other apparatus and instruments are inserted to human bodies by the work channel to realize the function of channels; right now, under the pressure of the gas in the column-shaped gas pocket, the work channel clamps the laparoscope and other apparatus and instruments, which has the function of preventing the channel from leaking under the working state of the channel. The invention can realize one window body and a plurality of single work channels, and then further decrease the surgery incision number of a patient, therefore, the working window has the advantages of simplifying surgery operations, reducing surgery operators, realizing fixed and reliable connection, reducing the surgery incisions, providing possibility for single-hole laparoscope surgeries and the like.

High-speed railway LTE system cell reselection system and method based on geographical location information

InactiveCN104168614ASimplify the cell reselection processreduce in quantity
The invention provides a high-speed railway LTE system cell reselection system and method based on geographical location information and relates to the technical field of mobile communication. The system comprises a base station arranged along a running track of a train and a vehicle-mounted device installed on the train, wherein a base station device comprises a receiving unit, a base station storage unit and a triggering judgment unit, and the vehicle-mounted device comprises a measurement unit, a sending unit, a vehicle-mounted storage unit and a control unit. According to the cell reselection method, a speed measurement result, lower than a preset threshold value, reported by the vehicle-mounted device is received on a source base station, a cell reselection process follows an R criterion, and if the speed measurement result is higher than the preset threshold value and the longitude and latitude information is consistent with data stored by the base station storage unit, the cell geographical location reselection process is started at the moment. On a high-speed moving scene, UE can fast reselect a reasonable target cell, and meanwhile it can be prevented that because of over-high running speed of a train, users can not surf the Internet.
