Double-layer bushing crisscross flexuosity restriction support with transverse diaphragm

InactiveCN101105054ASolve the problem of limited lateral expansionPossibility to avoid low-order bucklingShock proofingCruciformCompressible material
A cruciform buckling restrained brace with transverse partition double-layered bushing is provided. The core steel brace has a cruciform cross section, and comprises a middle segment (buckling segment) as major body with a smaller width, two distal end segments (extension segments), a transition segment between the buckling segment and the extension segment, and a transverse partition arranged in the middle of the buckling segment. Outer restraining steel bushings are positioned respectively at two sides of the transverse partition. An inner steel bushing is arranged between the outer restraining steel bushing and the core steel brace and has a cruciform cross section. The space between the inner steel bushing and outer restraining steel bushing is packed with fillers. An anti-adhesion material is coated tightly on the surface of the buckling segment and transition segment of the core steel brace, with a gap between the anti-adhesion material and the inner steel bushing and filled with a compressible material. The invention has the advantages of simple structure, low fabrication cost, suitability for streamline production, and wide application in high-rise buildings, towering buildings, and highway and railway bridges. The invention helps to increase the structural rigidity, improve the capacity of energy dissipation of the whole structure, and prevent earthquake disaster.

Double-layer bushing straight-line flexuosity restriction support with transverse diaphragm

InactiveCN100560884CSolve the problem of limited lateral expansionEliminates the problem of limited lateral expansionShock proofingCompressible materialCruciform
A linear buckling restrained brace with transverse partition double-layered bushing is provided. The core steel brace comprises a middle segment (buckling segment) as major body with a smaller width, two distal end segments (extension segments), and a transition segment between the buckling segment and the extension segment. The cross section of the buckling segment is shaped like the Chinese character 'Yi'. The cross sections of the transition segment and extension segment are cruciform. A transverse partition is welded in the middle of the buckling segment and provided outside with outer restraining steel bushings at two sides. An inner steel bushing is arranged between the outer restraining steel bushing and the core steel and has a linear cross section with respect to the buckling segment and a cruciform cross section with respect to the transition segment. The space between the inner steel bushing and outer restraining steel bushing is packed with fillers. An anti-adhesion material is coated on the surface of the core steel brace, with a gap between the anti-adhesion material and the inner steel bushing and filled with a compressible material. The invention has the advantages of simple structure, low fabrication cost, suitability for streamline production, and wide application in high-rise buildings, towering buildings, and highway and railway bridges.

Quickly mounted efficient energy-absorbing mining anchor rod

The invention discloses a quickly mounted efficient energy-absorbing mining anchor rod which comprises an expansion shell, a rod head, a rod body, a tray, an anti-seismic buffering material, a nut and a rod tail, wherein a tooth-shaped bulge is arranged on the outer surface of the expansion shell; matched threads are respectively arranged on the inner surface of the expansion shell and the outer surface of the rod head; a tapered bulge is arranged in the expansion shell; a tapered groove is arranged at the top of the rod head; a vertex angle of the tapered bulge is more than the vertex angle of the tapered groove; the thread is arranged on the rod tail; and the tray and the anti-seismic buffering material are respectively sleeved on the rod tail and are positioned and pre-tensioned by the nut. According to the invention, quick loading is realized by the anchor rod; mounting process is simplified; mounting time is shortened; driving speed is increased; the anti-seismic buffering material has a compressing buffering function when rock is burst, so as to effectively resist the dynamic loading effect at rock bursting moment; a certain anchoring force is kept by the anchor rod; and the anchor rod is prevented from being broken and invalid. Besides, the quickly mounted efficient energy-absorbing mining anchor rod has the beneficial effects of simple structure, convenience in mounting, high operability, and the like, and is widely applied to underground supporting for deep well.

Integral type level oil extraction wellhead equipment

ActiveCN101644149ASimplify follow-up workover operationsSimplify workover operationsSealing/packingLine tubingTubing hanger
The invention relates to integral type level oil extraction wellhead equipment, applied to ocean platform oil extraction. An upper cavity, a middle cavity and a lower cavity are arranged in a wellheadbody. The lower end of the upper cavity and the lower end of the middle cavity are respectively provided with a conical surface circular bead. An oil pipe hanger is arranged in the upper cavity. Thelower end of the oil pipe hanger is connected with screw threads used for connecting the oil pipe. The oil pipe hanger has an oil outlet channel. A pneumatic-hydraulic safety valve and a throttle valve are fixed on the outer wall of the wellhead body. A reduced flange, a paraffin removal valve and a tree cap are arranged on the upper end of the wellhead body. A completion sleeve hanger and a middle sleeve hanger are arranged in the middle cavity of the wellhead body. A WD sleeve hanger is arranged in the lower cavity of the wellhead body. The invention has the effects that: an integral hangingstructure with three hangers lowers the height of the wellhead and simplifies the installation procedure. A Christmas tree and relevant associated lines do not need to be removed during the subsequent workover job, thereby simplifying workover operation, saving disassembly and assembly time and simplifying the later workover operation.

Building form board perforating device

The invention discloses a building form board perforating device. The building form board perforating device comprises a frame body. An ascending-and-descending plate is arranged in a rectangular cavity inside the frame body in a sliding manner. An ascending-and-descending driving mechanism is arranged between the ascending-and-descending plate and the frame body and used for driving the ascending-and-descending plate to slide vertically along the inner wall of the frame body. A sliding base block and a horizontal sliding mechanism are arranged on the lower end face of the ascending-and-descending plate in a sliding manner, wherein the horizontal sliding mechanism drives the sliding base block to linearly slide leftwards and rightwards. A drilling platform is arranged below the sliding base block. A drilling motor is arranged at the lower end of the drilling platform. According to the building form board perforating device, improvement is conducted to overcome defects of an existing device; horizontal locating of a drill bit in the original device is separated into horizontal linear motion of a drill bit and rotation of a to-be-machined form board; the separation mode facilitates later-stage maintenance, and the mounting procedure is simplified; in addition, formation of an inclined drill hole is underlaid; and furthermore, an adjustment mechanism used for adjusting the inclination angel of the drill bit is arranged, and thus, adjustment of the inclination angel of the drill bit is completed; and the practicability is high.
