A vibration absorber of dynamically intermittent-operated type is prepared as engaging the first stage of reduction driving large gear with input shaft of reduction gear and free-jacketing it to the second stage of reduction driving gear shaft through rolling bearing, setting clutch / brake enabling to control separation and combination of the two between said large gear and said gear shaft, driving second stage of driving large gear and output shaft to be operated when clutch frictional disc is contacted and cutting off driving chain of the second stage gear when clutch frictional disc is released.

The invention relates to a manual assembly machine of a plastic pipeline assembly. The manual assembly machine of the plastic pipeline assembly comprises an assembly machine body. A plurality of groups of clamp bodies and a plurality of regulating components are arranged on the assembly machine body, wherein the clamp bodies are used for clamping objects to be assembled and the regulating components are matched with the clamp bodies. The regulating components are used for regulating the clamp force and assembling travel distance of the clamp bodies. A pipe groove and a positioning and flaring component are further arranged on the assembly machine body, wherein the pipe groove is used for containing a flexible pipe and the positioning and flaring component is used for fixing a protruding length of the flexible pipe and achieving flaring. The positioning and flaring component is arranged on the lateral sides of the clamp bodies. When the manual assembly machine of the plastic pipeline assembly is used, a clamping block of a connector and a clamping block of the flexible pipe are fixed through a three-coordinate detector after a relative angle between the clamping block of the connector and the clamping block of the flexible pipe is well adjusted, and assembling is accurately achieved by enabling the clamping blocks to be clamped on the clamp bodies on the assembly machine when the assembling is carried out. In addition, the manual assembly machine of the plastic pipeline assembly has the advantages of being small in size, capable of being pushed away freely due to the fact that trundles are arranged on the bottom of the assembly machine, and free of noise in an operation process due to the fact that the whole assembly machine is designed to be free of rigid impact.

The invention discloses a rotating wheel type block prevention device for a sewage or surface water source heat pump system, and belongs to the technical field of energy sources. The rotating wheel type block prevention device solves the problems that heat-exchange equipment and a pipeline of the sewage or surface water source heat pump system are blocked, backflushing return water is mixed with inflow water, suspended matters are wound at a filter opening, and the sealing difficulty and the working accuracy difficulty are high in the existing block prevention device. The rotating wheel type block prevention device comprises a housing, a speed reduction driving mechanism, a rotating shaft, a rotating wheel filter disc and division plates, wherein the interior of the housing is divided into two chambers by the rotating wheel filter disk; the two chambers are communicated through a plurality of filter through holes; each chamber is divided into two non-communicated sewage or surface water chamber units in a direction parallel to an axis by each division plate; and four water openings are communicated with the four chamber units respectively. The rotating wheel type block prevention device is used for block prevention of sewage or surface water, and is simple and reliable in structure.

The invention discloses an overall hoisting scaffold force feedback type anti-dropping locking mechanism. A main shaft is sleeved outside a central rod; a spring is arranged between the central rod and the main shaft; a locking rotating wheel is sleeved on outer shaft sleeves of left and right swinging arms; outer teeth are arranged on the outer circumference of the main shaft; the outer teeth are meshed with inner teeth arranged on the inner cavity wall of the locking rotating wheel; the left and right swinging arms are connected with the main shaft; the left and right swinging arms can be driven to rotate when the main shaft rotates; transverse locking press blocks are arranged at the upper ends of the swinging arms; the locking press blocks are capable of pressing left and right guide channel steel; the locking rotating wheel is matched and connected with the main frame so as to limit the ascending and descending of the vertical main frame; the meshing state between the main shaft and the locking rotating wheel is cancelled through an unlocking device. The locking mechanism can automatically locks up when accidents happen no matter in static operation or hoisting operation, and the locking mechanism can immediately locks up within a very short time, so that a whole scaffold body can be immediately prevented from falling and can be stopped after sliding downwards for a very short distance, the security property is improved, and security accidents are prevented.
