The invention belongs to the technical field of breaking hammers and particularly relates to a breaking hammer with an annular cutting disc. The breaking hammer comprises guide rails, a rotary driving mechanism, cushion blocks, the annular cutting disc, sawteeth, hydraulic rods and a drill rod, wherein the drill rod is arranged inside a drill rod sleeve through sliding fit of drill rod guiding blocks and drill rod sleeve sliding holes; a drill rod spring is arranged on each guiding block; when the drill rod beats in a reciprocating way for working, a function of resetting the drill rod is realized; the rotary driving mechanism can vertically move on the guide rails on the drill rod sleeve through the cushion blocks; under the supporting of a hydraulic supporting ring, three hydraulic rods which are uniformly arranged in the circumferential direction control vertical moving amplitude of the rotary driving mechanism through the stretching of the hydraulic rods; and a thin-wall support, an annular plate support and the annular cutting disc are mutually fixed together and can vertical move along with the rotary driving mechanism. According to the breaking hammer disclosed by the invention, circular sawteeth can be driven by rotation of the rotary driving mechanism to rotate for cutting reinforcing steel bars, cutting action is simple and reliable, and a certain practical effect is realized.

The invention belongs to the technical field of injection molds for automobile lamps, and provides a double-color molding self-locking slider structure. By the aid of the double-color molding self-locking slider structure, the technical problem of difficulty in using oil cylinders for medium and small molds due to large occupied spaces of the oil cylinders when self-locking functions of sliders are implemented by means of oil cylinder driving can be solved. The double-color molding self-locking slider structure comprises a slider body, a pull block, a triangular seat, a guide device, a limit device, self-locking devices and a driving device. The slider body, the pull block and the triangular seat are matched with one another by the aid of a T-shaped block, guide actions can be completely carried out, the limit device is arranged on the pull block, and accordingly accurate movement distances of the pull block can be guaranteed; shifting blocks are arranged on the driving device and areused for driving the pull block to move when molds are closed or opened, and elastic self-locking blocks are arranged on oblique wedges of the driving device and are used for locking the pull block when the molds are closed. The double-color molding self-locking slider structure has the advantages that the oil cylinders are replaced with double-color molding structures, accordingly, the cost can be reduced, the reliability of mechanisms can be improved, the requirements of structural designs under the condition of small spaces can be met, the service range can be greatly expanded, and the service lives of the molds can be prolonged.

The invention relates to a particle annular Couette shear flow experiment device. The technical solution is: including the casing, support rods, beams, shearing chamber, frequency conversion motor and transmission mechanism, the shearing chamber includes a chassis, an inner cylinder and an outer cylinder, the inner cylinder and the outer cylinder are coaxially arranged, and the inner cylinder One end of the cylinder is fastened coaxially with the chassis, there is a gap between the chassis and the outer cylinder, the other end of the inner cylinder is tightly connected with the beam, and the support rod is tightly connected with the beam and the upper cover of the casing; the transmission mechanism includes The slewing disk, the slewing support bearing, the driving shaft and the worm gear reducer, the outer cylinder and the slewing disk are coaxially fastened, the slewing disk is coaxially fastened with the inner ring of the slewing support bearing, the outer ring of the slewing support bearing is connected with the machine The upper cover plate of the shell is tightly connected, one end of the drive shaft is coaxially connected with the turntable, the other end of the drive shaft is coaxially connected with the output shaft of the worm gear reducer, and the frequency conversion motor is coaxially connected with the input shaft of the worm gear reducer. The experimental device of the invention has rich particle flow characteristics and high experimental precision.

The invention discloses a mold locking mechanism of blow molding equipment. The starting end of the slideway is located on one side of the vertical line of the hinge axis of the swing arm, and the tail end extends from the self-locking position, which is located at the hinge of the swing arm. On the other side of the vertical line of the shaft, the rollers of the roller assembly drive the swing arm to swing when rolling along the clamping guide rail to drive the toggle shaft to move relative to the slideway. When the toggle shaft moves from the beginning to the end of the slideway, the drive is connected The block and the mold locking shaft assembly rise, and when the toggle shaft moves into the self-locking position of the slideway, the latch pin has upwardly exited the socket, and self-locking is realized. The present invention does not need to be provided with locking nostrils and clamping pins that can be inserted into the locking nostrils as in the prior art, and will not produce strong impacts and loud noises as in the prior art, and at the same time, it will not Generally prone to unstable work, unreliable, and low service life.

The invention provides a self-balancing storage robot for dangerous places, comprising a self-balancing structure, the self-balancing structure includes a bottom plate, a rotating center column, a balance adjustment group and a balance plate; the middle part of the surface of the bottom plate is connected by the rotating center column and the middle part of the balance plate , the top of the rotating center column and the middle of the balance plate are hinged; the surface of the bottom plate is connected to the balance plate through a plurality of balance adjustment groups. The balance adjustment group includes a motor seat, a motor, a ball screw pair, a connecting seat and an adjustment column, and the motor is arranged through the motor seat. On the surface of the bottom plate, the connecting seat is connected with the motor coupling through the ball screw pair, one end of the adjusting column is hinged with the connecting seat, and the other end of the adjusting column is hinged with the balance plate. When the motor coupling rotates, the adjusting column is driven to rotate. Using this scheme, by adjusting the angle of the balance plate relative to the horizontal in any direction, to ensure that the material is stationary relative to the support surface, that is, to ensure the safety of the material, especially when transporting dangerous goods in a military product manufacturing plant, which has important safety significance.
