Scroll cable detecting robot

InactiveCN101214412ASmooth climbClimbing safetyClimbingRope railwaysDrive wheelCable stayed
The invention discloses a spiral line cable detecting robot which consists of a cart, an upper and a lower supporting hugging devices symmetrically distributed along the cable which are connected together. The robot is characterized in that the active cart is provided with a climbing device and a magnetic absorbing device; two supporting horizontal levers are provided with hugging devices; the climbing device includes a lithium battery fixed in the cart and a DC motor fixed on one side of the driving wheel in the cart; power of the DC motor is supplied by the lithium battery, and the DC motor drives the driving wheel of the cart to rotate by a drive axle, so as to drive the whole robot to spirally climb along a water transmission line of the cable; the hugging devices and the magnetic absorbing device work together to tightly press the driving wheel onto the surface of the cable. The climbing device can rotate for any degree relative to the cart, so as to adapt to the water transmission line with different thread pitch; power supply by the lithium battery is more suitable for the environment of high-altitude operation; the robot is also provided with a descending device, which is safer and more reliable in use. The invention has simple and reasonable structure, is convenient in maintenance, can have high climbing speed, is applicable in detection of the spiral line cable of large cable-stayed bridges as well as lamps and other rod types.

Method for preparing continuous fiber multiaxial fabric reinforced thermoplastic composite material

The invention discloses a method for preparing a continuous fiber multiaxial fabric reinforced thermoplastic composite material. The prepared continuous fiber multiaxial reinforced thermoplastic preconsolidating material is taken as a base material of the composite board, and combined with other functional materials for forming a novel material system which can be used for producing multiaxial fabric reinforced thermoplastic composite materials for different industries and solving the technical bottleneck that different materials have different composite bonding difficulties. According to the invention, the prepared composite material is constructed by continuous fiber multiaxial direaction; materials have the characteristics of resilience and uniform stressing on different directions. In addition, light sandwich panel formed by a honeycomb core material provides higher impact strength of materials, which is suitable for preparing structural parts and interior decorative parts in the field of railway car containers of navigation and aviation. The product of light-weight flame retardant can be recovered and used, and is more suitable for industrialization scale production of the warp knitting industry organization.

Methods and apparatus for the repair of hernias

The present invention relates to devices and methods for the repair of hernia. One method for repairing a hernia the steps of making an incision through a skin layer of a patient near the hernia, creating an entrance into the preperitoneal space above the peritoneum at a location above the hernia, identifying and freeing a hernia sac, creating a pocket in the preperitoneal space, directing a surgical patch down through the incision and into the preperitoneal space, and expanding the surgical patch in the preperitoneal space. The method further includes the steps of inserting a distal end of a surgical fastening device through the incision and into the surgical patch, actuating the surgical fastening device to drive a fastener through the surgical patch and into the tissue of the patient, moving the distal end of the surgical fastening device to another location, actuating the surgical fastening device to drive a second fastener through the surgical patch and into the tissue of the patient, and closing the incision with stitches. One surgical apparatus for repairing a hernia includes a surgical stapling instrument for applying at least one surgical staple to fasten a surgical hernia patch to internal body tissue. The surgical instrument includes a handle assembly have a longitudinal axis. A staple cartridge housing is mounted to the handle assembly and is adapted to receive the at least one staple. The staple cartridge housing is dimensioned for insertion through an incision and has a staple actuator mechanism for applying the at least one staple into tissue. An actuation mechanism is operatively coupled to the staple actuator mechanism to operate the staple actuation mechanism.

Rock mass structural surface shear test method and device

The invention discloses a rock mass structural surface shear test method, which comprises the following steps of firstly, cutting a rock mass test piece into a cuboid and marking a vertical axis line and a horizontal axis line; then adjusting an adjusting rod, fixing the rock mass test piece by a movable steel baffle, enabling the vertical axis line of the rock mass test piece to coincide with the vertical axis line of a normal loading mechanism, enabling the horizontal axis line of the rock mass test piece to coincide with the horizontal axis line of a shear loading mechanism, and enabling the structural surface of the rock mass test piece to be located above the movable steel baffle; carrying out grading force application on the rock mass test piece by the normal loading mechanism from the vertical direction, and carrying out grading force application on the rock mass test piece by the shear loading mechanism from the horizontal direction; receiving the force application data of the normal loading mechanism and the shear loading mechanism and the displacement values of a normal displacement sensor and a horizontal displacement sensor by a computer, and analyzing and calculating the data. The invention also provides a rock mass structural surface shear test device. According to the invention, the stress bearing condition of a rock mass in the reality can be simulated, and test data are accurate and reliable.

Method for planting organic passion fruit trees

The invention discloses a method for planting organic passion fruit trees. The method includes the steps of variety selection, site selection, soil preparation, soil pH adjustment, establishment of a passion fruit tree foundation, field planting, reshaping and pruning, field management, blossoming, fruit yielding and the like. According to the method, organic fertilizer and a low-toxicity prevention method are adopted in fertilization and pest control, so that the pulp of produced passion fruits is full of yellow fruit juice, the content of sugar is high, the color is bright, the yield reaches up to 2 tons per mu each year, pollution is avoided, and five seasons of fruits can be harvested each year. The successful planting of the organic passion fruit trees provides a theoretical and practical basis for creating incomes of local farmers. According to the method, a leeward apricus flat ground is selected, and the place where a good source of water is obtained, the soil layer is thick, fertility of the soil is above the average and transportation is convenient is used as a planting foundation, so that it is guaranteed that the passion fruit trees can grow in a good environment, the roots of nursery-grown plants are planted in furrows and exposed to the sun, hence, the roots can better absorb sunshine, and fertilization and weeding are further facilitated.
