摘要:
Silicone (93) is placed between an upper die (65) and an injection-pressing rubber-lid upper die (67), and the silicone injection passage (75) is pressurized by the injection-pressing rubber-lid upper die (67). With this, the silicone (93) is caused to flow into an injection port (77) through the silicone injection passage (75). Then, sequentially through the injection port (77) and the disc silicone-flow passage (73), the silicone is caused to flow toward an inner periphery (71a) of a silicone injection space (71). Further, the silicone flows between both circumferential sides of the silicone-flow deflection region (81). In this way, the silicone flows in a peculiar manner in conformity with a shape of the silicone-flow deflection region (81).

A suspension support device (10) is provided movably on the upper surface of a building (1) for suspending, by means of ropes (4), an outer wall working machine (40) having fitting and moving members (41) which can be fittedly engaged in a pair of guide grooves (3) formed vertically on an outer wall surface (1B) of the building, and lowering and lifting the outer wall working machine along the guide grooves. The device includes a main body (11B), an arm structure (12) connected to the main body, a holding unit (20) connected to the arm structure in a manner to be movable forwardly and rearwardly, laterally and pivotable about a vertical axis and including a pair of holding guides (22) provided at an interval equal to an interval of the pair of guide grooves and being capable of receiving the fitting and moving members, an arm structure drive unit for driving the arm structure to move the holding unit, sensors for detecting the upper edge of the building, and a drive control system for controlling driving of the arm structure drive unit in response to detection information supplied by the sensors. The drive control system controls driving of the arm structure in response to detection information supplied by the sensors to move the holding unit to a position at which the holding guides align with the guide grooves.

A device for suspending a working cage includes an arm (2), a swivel arm (3) mounted rotatably horizontally to the end portion of the arm (2), a first sheave (18, 19) mounted rotatably horizontally to the arm (2) at a location behind the end portion to which the swivel arm (3) is mounted, and a second sheave (23, 24) mounted rotatably horizontally to the swivel arm (3) in front of the center of rotation of the swivel arm (3). The first and second sheaves have the same diameter and are formed with at least two vertically arranged wire rope engaging grooves. At least two wire ropes (40a, 40b, 42a and 42b) fed from a winding device and attached to a working cage through these sheaves cross each other between the first sheave and the second sheave. The distance between the center of rotation of the swivel arm (3) and the center of rotation of the first sheave (18, 19) is determined to be equal to the distance between the center of rotation of the swivel arm (3) and the center of rotaion of the second sheave (23, 24). By this arrangement, entwining of wire ropes and inclination of the working cage due to imbalance in length of respective wire ropes can be prevented.

A wire rope supply path length adjusting device (80) for adjusting change in length of a wire rope supply path caused by pivoting of a pivotable arm (20) pivotably supported on a base member (10) for suspending an object to be supported by means of wire ropes includes a pair of fixed pulleys (81) of the same diameter provided rotatably about axes of rotation parallel to a rotation axis of the pivotable arm across the wire rope supply path at positions which are spaced from the rotation axis (second axis) of the pivotable arm on the side of said base member, and a pair of movable pulleys (82) of the same diameter provided rotatably about axes of rotation parallel to the rotation axis of the pivotable arm across the wire rope supply path at positions which are spaced from the rotation axis of said pivotable arm on the side of the pivotable arm. The wire ropes (4) are caused to engage on the pulleys on the pivoting side among the respective pairs of pulleys and the diameters of the respective pairs of pulleys and the distances of the respective pairs of pulleys from the rotation axis of said pivotable arm are selected at values at which length of the wire rope supply path between the respective pairs of pulleys is maintained substantially constant regardless of change in an angle of rotation of said pivotable arm.

A rope traction device (30) includes a sheave (32) which is rotated to cause a traction rope to be wound on the sheave. The rope traction device thereby is moved along the traction rope. The rope traction device includes a traction rope inlet (51b) for feeding in the traction rope, a traction rope outlet (38) for feeding out the traction rope, a traction rope locking device (50) provided in the vicinity of the traction rope inlet for detecting increase in relative moving speed of the traction rope and thereupon locking the traction rope, an auxiliary rope locking device (70) provided in the vicinity of the traction rope inlet for detecting relative moving speed of an auxiliary rope suspended from above the rope traction device and thereupon locking the auxiliary rope, a connecting device for connecting the traction rope locking device with the auxiliary rope locking device in such a manner that the traction rope locking device and the auxiliary rope locking device can detect increase in the relative moving speeds of the respective ropes independently from each other and both of the locking devices are brought into a locking state when either one of the locking devices has detected increase in the relative speed.

An outer wall cleaning robot includes an arm (14) pivotable about a first rotation axis (I) and a rotational body (15) supported by the arm for pivotal movement about a second rotation axis (II). The rotational body can be driven independently of a pivotal movement of the arm. To the rotational body are attached respective mounting mechanisms (17, 19) for a wiping squeegee (18) and a receiving squeegee (20).
