Imaging apparatus

In the imaging apparatus of the invention, a camera assembly 200 including a camera 202 is mounted on and supported by a base 110 in a pivotally rotatable manner both in a vertical direction and in a horizontal direction to allow tilting motions and panning motions of the camera 202. The camera assembly 200 is supported on an assembly fixation structure 114 of the base 110 to allow the tilting motions of the camera assembly 200. The assembly fixation structure 114 is panned relative to a base foot 112 of the base 110. A panning rotation gear 175 for the panning motions of the camera 202 is fixed on a ground plate 121, which has a positional change relative to a pedestal plate unit 130 in the assembly fixation structure 114. A tilting motor 160, a panning motor 162, and relevant vertical and horizontal rotation transmission mechanisms required for the tilting motions and the panning motions of the camera 202 are collectively arranged on the pedestal plate unit 130 of the assembly fixation structure 114. The tilting motor 160 and the panning motor 162 are arranged in an attitude having respective output shafts in the horizontal direction and are disposed to face each other across a pivot shaft fitting element 135 on the pedestal plate unit 130. This arrangement of the invention enables further downsizing of the whole imaging apparatus applied to, for example, a security camera.

Grinding head for a mobile grinding machine and mobile grinding machine comprising such a grinding head

The invention concerns a grinding head for a mobile grinding machine which is suitable for grinding floor surfaces, and a mobile grinding machine comprising such a grinding head. The grinding machine is driven by a motor and has a rotatable planet disc and grinding heads (5-7) rotatable relative to this. The grinding heads (5-7) comprise a carrier (8) which is designed to be rotated by means of the motor, and a grinding disc (9) designed to be driven by the carrier (8) by means of a coupling element (10). The coupling element (10) comprises a multiplicity of plates (11-13) which are stacked on each other, each with a central opening (14) and drain holes (15) distributed around this, and a compression spring (16) which extends through the central opening (14) of the plates (11-13) and by means of screw elements (17) is clamped between the carrier (8) and the grinding disc (9). The screw elements (17) extend through the drain holes (15) of the plates (11-13) and are arranged to connect, alternately in a circular direction around the central opening (14) of the plates (11-13), the carrier (8) with the plate (13) nearest the grinding disc (9) and the grinding disc (9) with the plate (11) nearest the carrier (8). A coupling element is also shown for a mobile grinding machine for grinding a stone floor.

Portable dry-wet dual-purpose smoothbore pipe and line bore pipe inner surface wiping and cleaning device

The invention discloses a portable dry-wet dual-purpose smoothbore pipe and line bore pipe inner surface wiping and cleaning device. Device wiping liquid is supplied through a quantitative spraying method, and supplying is even and controllable. Long-time and durable work of a standby power source is achieved through a small-power wiping and large-diameter pipeline mechanism. The device is compact and ingenious in structure and light in weight, and carrying and field work are facilitated. A ball head washing handle brush has the automatic advancing and retreating function, the axial force and deformation stressed by a flexible shaft are eliminated, abrasion of the flexible shaft is relieved, and rotation can be achieved in a labor saving mode. A reliable sealing structure is adopted, and a solution and gas do not leak. The device solves the problems that a current wiping machine depends on a power source and cannot wipe a large hole, carrying is not convenient, liquid supplying cannot be quantitative, spraying cannot be achieved, and equipment is corroded through leaking liquid. The wiping method is divided into a dry wiping mode and a wet wiping mode, spraying is not carried out during dry wiping, the ball head brush is directly used for rotary wiping, and during wet wiping, spraying and liquid supplying are carried out at the ball head brush while the ball head brush carries out rotary wiping.

Stepless speed change device

The invention relates to a stepless speed change device which comprises an input shaft, an input spiral gear, an output shaft and an output spiral gear. The input spiral gear comprises an input cone and input teeth, and the input cone and the input teeth are rotationally connected. The input teeth are spirally arranged by multiple circles on the outer circumferential surface of the input cone along the axis of the input cone. The thread pitches of the input teeth are the same, and the tooth numbers of multiple circles of the input teeth are integrally multiplied according to equal proportion. The output spiral gear comprises an output cone and output teeth. The output cone can slide along the output shaft and transmits torque to the output shaft. The output teeth are spirally arranged by at least one circle on the outer circumferential surface of the output cone along the axis of the output cone. The spiral direction of the output teeth is opposite to that of the input teeth. The thread pitch of each circle of the output teeth is the same as that of each circle of the input teeth. The input spiral gear is meshed with the output spiral gear. Output torque of the stepless speed change device is considerably larger than that of a steel-belt stepless speed change device, so that the stepless speed change device can be applied to large-displacement off-road vehicles and heavy trucks.
