This invention relates to a tuned damper and a monorail for controlling vortex-induced vibration of a monorail main beam. The damper includes a damping box, a mass block assembly, a spring, a guide shaft, a guide assembly, and damping fluid. One end of the spring is connected to the bottom of the damping box cavity, and the other end is connected to the bottom of the mass block assembly. One end of the guide shaft is connected to the bottom of the damping box cavity, and the other end is connected to the top of the damping box cavity, passing through the mass block assembly. The guide assembly is fixedly connected to the mass block assembly and symmetrically arranged on both sides of the guide shaft. The damping fluid is disposed within the damping box cavity. The advantages of this invention are: 1. By limiting lateral displacement through the guide assembly, stability is increased; 2. Adjusting the base allows for adjustment of the gap between the roller and the guide shaft without affecting the vertical vibration of the mass block assembly, thus promoting stable and long-term operation of the device; 3. The mass block assembly optimizes the adjustment efficiency.

This invention discloses a crusher crushing plate stroke adjustment transmission device, including a frame, a rotor assembly, a crushing plate, and a stroke transmission assembly. The crushing plate includes an upper crushing section and a lower crushing section distributed along the material flow direction, which are connected by a hinge structure. The stroke transmission assembly includes a drive motor, a worm gear reducer, and an adjusting screw. The adjusting screw passes through the frame and is connected to the crushing plate through a ball-end self-aligning connection structure. A guide floating sleeve is provided between the adjusting screw and the frame. When the crushing plate undergoes an angle change during operation, the ball end can generate relative rotation within the self-aligning seat, thereby adapting to and compensating for the angle change. Through the synergistic effect of the above structures, the off-center load on the adjusting screw can be reduced during crushing plate adjustment, improving the operational stability of the adjustment mechanism under impact conditions.

The utility model discloses a grid slag presser and a pore plate cleaning mechanism thereof, and belongs to the technical field of grid slag pressing equipment. The pore plate cleaning mechanism comprises a brush base, a driving mechanism drives the brush base to move linearly through a transmission screw, the brush base comprises a brush fixed supporting seat and a brush movable supporting seat, and the whole brush movable supporting seat is of an arc-shaped structure matched with the outer wall of a squeezing pipe to be cleaned. And the brush is mounted on the brush fixing and supporting seat in a sliding manner along the radial direction. According to the scheme, the pore plate cleaning mechanism is additionally arranged at the bottom of the squeezing pipe to clean the bottom of the squeezing pipe and is matched with the flushing mechanism at the top, so that the cleaning range of the squeezing pipe in the circumferential direction can be enlarged, and blockage of water outlet holes in the squeezing pipe can be reduced.

The utility model discloses an optical cable reinforcing steel wire spraying and oiling mechanism, which belongs to the technical field of steel wire oiling and comprises a machine tool, a first connecting column is fixedly connected onto the machine tool, a first conveying roller is mounted at the top end of the first connecting column, and a second conveying roller is arranged on one side of the first conveying roller. The bottom side of the second conveying roller is connected with a sliding block through a bearing. According to the optical cable reinforcing steel wire spraying and oiling mechanism, before spraying and oiling are conducted on a steel wire, an operator starts a second motor to change rotation of a gear, the gear drives a rack and a first motor to move, the first motor drives a second conveying roller to move, and the second conveying roller drives a sliding block to slide in a sliding groove; according to the spraying and oiling mechanism, the steel wire can just pass through the gap between the first conveying roller and the second conveying roller, an operator can conveniently adjust the gap between the first conveying roller and the second conveying roller, then the steel wires with different thicknesses can be conveyed, and the functionality and the universality of the spraying and oiling mechanism are improved.

The utility model discloses a kind of group crown blade vibration test experimental devices with adjustable gap, it is related to group crown blade vibration test technical field, including base, vice body and clamping plate.The utility model discloses group crown blade vibration test experimental devices with adjustable gap, by setting force sensor and exciting force of exciting rod main part is acted on crown blade main body, and then make crown blade be excited, the influence law of the vibration response and the vibration reduction characteristic of crown blade system under different gaps are discussed, and the optimal parameter is obtained according to its vibration law;The gap size between adjacent leaf crown is determined by the locking adjustment of clamping plate, gap piece and vice body, and then the gap size is measured by calipers, and gap piece of different thickness is matched, so that the gap between adjacent leaf crown can be adjusted, to ensure that staff can study the influence of the gap between adjacent leaf crown on system vibration characteristic.
