Abstract

When a wire rope (55) is broken, the wire rope (55) will sag from the state in which the wire rope is tensioned with a predetermined tension. At this time, a pin (71) is pressed toward a movable support (42) by a biasing force of a spring (73), and the tip of the pin (71) is brought into contact with the surface of the movable support (42). When the support arm (43) is ascended or descended with respect to the movable support (42) and the pin (71) is arranged at a position facing the hole (65) formed in the movable support (42), the tip of the pin (71) is entered into the hole (65), so that the pin (71) and the hole (65) are engaged with each other. Thereby, the support arm (43) is fixed with respect to the movable support (42).

Dependent claims

An X-ray imaging apparatus comprising:

a support member configured to support an X-ray tube or an X-ray detector;
a pair of wire ropes configured to support the support member in a suspended manner;
and
a pair of engagement mechanisms each including an engaging member movable between an engagement position engageable with a hole formed in a fixed side member and a separation position spaced apart from the hole and a biasing means biasing the engaging member toward the engagement position, the pair of engagement mechanisms being provided on the support member so as to correspond to the pair of wire ropes,
wherein the engaging member of the engagement mechanism is arranged at the separation position against a biasing force of the biasing means in a state in which the engaging member is in contact with the wire rope.

An X-ray imaging apparatus comprising:

a support;
a support arm arranged in an ascendable and descendable manner with respect to the support and configured to support an X-ray tube and;
a pair of pulleys provided on an upper portion of the support;
a pair of wire ropes each wound around the corresponding pulley with one end of the wire rope fixed to the support arm and the other end thereof fixed to the support;
and
a pair of engagement mechanisms each including an engaging member movable between an engagement position engageable with a hole formed in the support and a separation position spaced apart from the hole and a biasing means biasing the engaging member toward the engagement position, the pair of engagement mechanisms being provided on the support arm so as to correspond to the pair of wire ropes,
wherein the engaging member of the engagement mechanism is arranged at the separation position against a biasing force of the biasing means in a state in which the engaging member is in contact with the wire rope.
